Universal Rotating Intensive-Care-Bed

Goals:

Simplify care work, avoid the physical efforts of the caregivers/nurses.
Reduce the number of caregivers per long-term patient.
Mechanical (automatic) change of supine position, lateral position, prone position with reduction of lung problems (ARDS) and prevention of bedsores.
Automatically remove excretions of the long-term patient (luxury version).
Stimulation of the limbs of the patient (movement, massage, vibration) in order to shorten his post-treatment /REHA phase and reduce the after-effects.
Preserving the spirits of the awake patient through e-book, smartphone, TV, computer / Internet / YouTube and through simplified secure visitor contact.

Short description*:

Rotatable hollow body (tube system), can be erected up vertically, upper part can be opened or lifted, on a stable mobile frame, in reverse position the lower part.
The patient is transported with a special crane and lowered into the tube system, into the lower part, adjusting supports and girders. Alternatively, the patient can be placed into the pipe system with 4 to 5 strong caregivers.
Supply and measurement systems are fed to the devices and machines on the side of the tube system or at the end of the patient’s head.
The patient is fixed on all sides with supports and support surfaces, which are covered with elastic skin-compatible material (cushions, pillows) and are adapted to the patient’s surface.
These supports are universal-movable and are adjusted in length.
Large windows allow in the prone position operation of smartphone, computer, laptop and reading of e-book.
Large windows allow, in vertical supposition, simplified food intake as well as eye contact with the visitor and, if allowed, lateral contact with the arm.
If the top is lifted off, the patient (strapped on) can do movement exercises with his legs in vertical supposition, possibly supported.

TOILET of the luxury version:

When the toilet is activated by the patient or by the caregiver, the patient is automatically moved into a slightly inclined supposition, with clothing and the blanket/cover being pulled upwards to the upper body.
By patient, automatically or by nursing staff, rays are triggered with warm water, with their angles being adjusted to the patient with flexible syringes.
The outflow of the water along the legs is prevented with rings/cuffs around the thighs of the patient.
Due to the inclination of the tube system, the excretions are flushed downwards and leave the tube system into a container or directly into the sewerage system.
Odor spread is prevented by simple measures.
After the rinsing process, the patient and the environment are dried with warm air.
Then the patient is automatically covered again. Its position can then be freely adjusted mechanically.

Quick cleaning and body care of the patient, change of clothing and blankets:

In supposition of the patient, its front can be very quickly treated when the upper part of the tube system is opened or raised.
Accordingly, the patient’s back can be quickly treated when the underside of the tube system is opened or raised.

Mental and physical activation of the patient:

In supposition of the patient and after lifting the upper part of the tube system, he/she can do limited leg exercises, supported by aids and assistants.
In the horizontal prone position and after lifting the lower part of the tube system, the patient can receive massages.
In the luxury tube system, vibrators are attached to various supports and support plates, which can be activated by the patient or the nursing staff to reduce muscle loss by lying for a long time.
In supposition with the vertical position of the tube system, the patient can absorb and drink food with the large window open, and with the window closed, see visitors and communicate with them. With air lift and air exhaust on the ceiling, the risk of infection is minimized.
In a horizontal prone position and after lowering the arm supports/carrier, the patient can read e-book, operate smartphone, computer, TV and lighting and observe through the large window. Adaptation for wearers of glasses.
The initial skepticism of the patient because of the closed tube system will mostly give way with the physical and mental activities. Also, the patient himself can open the system anytime.

Operation and automatic of the tube system

At the foot of the tube system, a tableau is attached for the nursing staff with status display of the patient (fever, blood pressure, heart rate, breathing, oxygen content blood, etc. with fixed supply of the data from the devices at the head end) as well as with switches / buttons for the specified functions rotation and straightening of the tube system, lifting the upper part and the lower part, setting up the inclination of the tube system and activation of the toilet system, ventilation, temperature regulation of the tube system and activation of the vibrators and the entertainment devices at the head-end.
The change from back to prone position and vice versa can be automatically or periodically adjusted computer-controlled.
Within the tube system, there are switches on both sides of the patient, with which the patient can perform the position change, the vertical position, the toilet actions and operate the consumer electronics / volume by hand or with voice command.
All data are permanently directed to the nursing staff’s lounge.
With an easily accessible and visible emergency switch or microphone, the patient can request help at any time.
Continuous emergency power supply required.

Estimated development times: 6 months for primary design with help of intensive-care specialist, 6 months for production of prototype, 3 months for testing and official safety checking.

In case of emergency these times can be reduced, by using full resources and participation of inventor, to total 4 months. The development and fabrication expenses are amortized by daily fees of bed utilization.

Stop Corona Infection by Upward Airflow/Convection

Stop Corona Infection by Upward Airflow/Convection

Most Corona infections inside buildings occur from aerosol-virus-particles floating and enriching in the air. By modest upward or crossing airflow these aerosols are diluted and removed with little effort the details of which have to be proposed by a taskforce “Prevention & Planning” consisting of virus/infection-, aerosol-, aerodynamics-, HVAC-experts and civil engineers/architects. With timely introduction of compulsory upward airflow (summer 2020) millions of infections could have been prevented!

It is well accepted that people outside of buildings, in fresh air, have low risk of Covid-19-infection due to some air breeze and due to prompt three-dimensional dilution of the aerosol concentration. Each breathing of an infected person is immediately dispersed so that the chance of reaching the critical concentration for infecting even neighbor persons is very small.

In this project the aerodynamic principle is applied to people assemblies inside buildings by application of upward airflow: Aerosol-virus particles are moved upwards, by specific ventilation, and then moved out of the room. Thus, the infection of neighbor students or people can be excluded if the other precautions like hand disinfection, distance of ~70cm and wearing masks are followed to prevent infections from droplets. There are several ways of installing upward airflow: by air inlet near the floor, at the bottom of the room and by extracting air under the ceiling with tubes and holes, by arranging a thin light-weight ceiling with holes, by a deck ventilator, or by small battery ventilators on or inside the tables. Air is extracted by a small ventilator outside the room and diluted, or it can be in-situ disinfected by HEPA filter, by UV-C radiation, or by heating. The airflow action can simply be checked by slight motion of a candle or of a small wind vane on the table. The action of upward airflow has been widely confirmed, demonstrated and published.

Corona crisis will continue for years, in analogy to influenza, even with (temporary)immunity of healed persons and with repeated vaccination required by virus mutation.

The installation costs of airflow are small compared to the enormous social, education, cultural, economic losses of the Corona crisis. Unemployment and short-time working will be reduced, insolvencies and personal catastrophes can be prevented with end of shutdown and of personal restrictions, with a return to nearly normal life!

With general compulsory upward airflow, life can be normalized and schools, restaurants, fitness centers, concert- and sports-halls opened when personalized seats are organized which allow tracking in case of an infection. Anyhow, the vaccination certificate will allow freedom and travelling. Upward airflow should also be installed in Intensive-Care-Stations and in old-people homes

A national Taskforce “Prevention & Planning”, in German: “Prävention und Planung”, politically independent, will consult the government for realization of general airflow conditions: Experts in the areas of virus-aerosol, virus-disinfection-technology, aerosol-aerodynamics, intensive-care, ventilation/HVAC, civil engineering, architecture, representatives of education, gastro/hotel, shopkeeper, artists, events, tourism, sports and fitness, business management/statistics. 17.3.2021 HJS

Fire Extinction and Prevention

Fire Extinction and Fire Prevention

The recent catastrophic fires in California, Australia and southern Europe have destroyed forests and steppes including wildlife, city areas and numerous houses and caused huge damages and tragedies. There is fear that number and dimensions of fires will increase due to climate change. This project describes novel approaches of fire extinction in buildings and to prevent the progress of fires outside the settlements. The principle is demonstrated with the fire of Notre Dame cathedral in Paris April 15, 2019.

Fires are a common threat to mankind, to nature and cultural heritage, to forests and steppes including wildlife, to buildings including habitants, and to historical buildings and churches. A prominent terrifying example was the fire of Notre Dame cathedral in Paris April 15, 2019. Despite the intensive water flushes from the top the intense fire with high flames continued for about five hours whereas with a novel approach it could have perhaps been stopped in 30 minutes.

There are three prerequisites for fire: 1) fuel which can be solid, liquid, gas or gas from decomposition of solid, 2) high temperature and 3) air (oxygen). The goals of firefighters and of applying fire extinguishers are to separate fuel from air and to cool the fire by powerful water splashing or by fire-extinguishing fluid. In case of Notre Dame the water flushing from top, as one could see for hours in TV, had practically no effect since it produced water vapor which has much lower density than air and thus escaped and did not reach the burning wooden beams and cool the fire. Finally, the fire stopped when most of the fuel, the wooden beams, had burnt, the high flames had stopped, and the water could reach the glowing fire.

In this project a novel approach to extinguish fire based on the principle of separating fuel from air was developed for efficient extinguishing fire inside buildings and localized fires outside, and from preventing the advancement of wildfire in forests and steppes. Specific measures will prevent the progress of fire to approach housings and cities. The costs of these measures are small compared to the lives and values at risk. Patent application in progress.

Barrier Dikes prevent North Sea Flooding and recover large land surfaces

Barrier Dikes prevent North Sea Flooding and recover large land surfaces

Allgemeine Beschreibung der Barrierendeiche

Die jetzigen Deiche sind das Ergebnis jahrhunderte-langer Erfahrungen. Die relativ flachen Neigungswinkel sollen die Wellenenergie reduzieren. Durch die Bauweise und die Bepflanzung soll Langzeitstabilität erreicht und Erosion reduziert werden. Allerdings benötigen die herkömmlichen Deiche durch die kleinen Neigungswinkel und grosse Breite enorme Landoberflächen, zum Teil bis zu 100m. Zusätzlich stellt die durch steigende Meereshöhe und heftiger werdende Stürme erforderliche Erhöhung der Deiche grosse Anforderungen, die sehr grosse finanzielle Mittel beanspruchen.

Die neuen Deiche folgen dem Prinzip der Reflektion an der vertikalen Wand. Senkrechte Barrieren ragen aus dem Meer, wobei die Aktion der Meereswellen auf die vergleichsweise kleine aus dem Meer herausragende Oberfläche konzentriert wird. Diese Oberfläche wird weiter reduziert, wenn durch Sturm der Meeresspiegel ansteigt.
Eine wichtige Komponente des neuen Deiches besteht aus den transportablen Parapets, die oben an die senkrechte Barriere angehängt werden und die die aus dem Meer herausragende Barrieren-Oberfläche gegen die Einwirkung der Wellen schützen und die durch ihre Form das «Overtopping» verhindern.
Diese Parapets bestehen aus Spezialbeton mit erosionsfesten Oberflächen, zum Beispiel aus V4A-Stahl, oder sie bestehen aus festen V4A-Stahlkörpern, die mit verfestigtem Sand oder anderen Materialien gefüllt sind.

Eine oben auf der Barriere verlaufende Strasse dient dem Transport der Parapets, deren Kontrolle und Überwachung und deren Austausch, wenn die äussere Stahlwand nach vielen (>100?) Jahren beschädigt ist.
Ein besonderer Vorteil der neuen vertikalen Deiche besteht in deren einfachen Erhöhungsmöglichkeit durch Fertigelemente, die auf der oberen Deichstrasse transportiert und oben aufgesetzt werden. Dabei werden wiederum nachfolgend die Parapets oben eingehängt.
Die Strasse dient neben der Transport- und Kontroll-Funktion auch dem Tourismus, wobei durch lokale Fahrbahnerhöhungen der Ausblick auf Meer und Landschaft erleichtert wird.
Durch die vertikale Anordnung der neuen Deiche werden grosse Landoberflächen frei. Die Figur zeigt die geplante Deicherhöhung Bremen und dessen Landbedarf im Vergleich zum vorgeschlagenen Barrierendeich (rechts auf der Seite des Meeres).

Die vertikale Barriere und deren neue Bautechnologien sowie die transportablen Parapets sind patentiert.

Bauphasen:

Produktion der Barrierendeich-Container und der Parapets in der Werft.
Einrichten des Sturmwellen-Schutzstahlnetzes auf dem Meer vor der Baustelle.
Herstellen der provisorischen Baustrasse auf der Meeresseite des alten Deiches.
Rammen der Stahlrohre/-Profile auf der Küstenseite des vorgesehenen Barrierendeiches in den Boden/Sand.
Baggern (Dredging) des Grabens für den Barrierendeich-Container..
Transport des Barrierendeich-Containers (flach auf dem Wasser) und Absenken in den Graben (mit Raupenkran senkrecht).
Rammen der Stahlrohre/Profile meerseitig in den Meeresboden.
Mechanische Verbindung der Stahlrohre/Profile mit dem Barrierendeich-Container (beidseitig, mit Abstandhalter).
Füllen des Deichzylinders mit Steinen und periodisch mit speziellem Flüssigbeton.
Bau der Top-Deich-Betonstrasse (mit Stahlrohr/Profil für spätere Deicherhöhung und zum Anhängen der Parapets) auf dem Barrierendeich-Container mit Schutzmauern auf beiden Seiten.
Abtragung des alten Deiches und Erstellung der landseitigen Verstärkung des Barrierendeiches.
Transport und Anhängen der Parapets.

Prinzip und Vorteile der Barrierendeiche

Die Energie der Sturmwellen wird nicht wie üblich durch die schwach ansteigende Höhe der Erd-Sand-Deiche sukzessiv abgebaut, sondern wird an einer senkrechten Barriere reflektiert. Dies bedingt

Grosse mechanische Stabilität der Barriere mit dessen Dicke, Konstruktion und Standfestigkeit im Boden, der oft aus Sand und Schlick besteht. Der Druck einer starken Tsunami-Impulswelle wurde zu 7 Tonnen pro m2 berechnet [1].
Position und Stabilität werden landseitig durch eine steile Böschung verstärkt.
Erosion und Korrosion wird durch Materialwahl und durch den transportablen Parapet weitgehend verhindert. Reparaturen der Barrierendeiche werden frühestens nach etwa 100 Jahren erwartet.
Je nach Sandtransport auf der Meeres-Seite kann der vertikale Charakter der Barrierendeiche durch gelegentliches Baggern erhalten bleiben.
Die kompakte Bauweise erlaubt kurze Bauzeit.
Die durch Klimawandel erforderliche spätere Erhöhung der Barrierendeiche ist einfach und effizient.
Die Durchlässigkeit für Meerwasser ist vernachlässigbar, so dass die Salzkontamination in den Marschen abgebaut werden kann.
Der Verbrauch an Sand und Kleie ist gering im Vergleich zu konventionellen Deichen.
Die Gestehungskosten der Barrierendeiche liegen in der Grössenordnung der Kosten für konventionelle Deiche (4 bis max. 9 Mio. Euro pro km).
Der Landgewinn ist enorm: für 1’100km Nordseeküste entspricht dies 11’000 Hektar oder 1.4 Mrd. Euro bzw. 1.3 Mio Euro pro km Barrierendeich.
Ausserdem können die Halligen gerettet und voll nutzbar erhalten werden.

Weitere Vorteile der Barrierendeiche sind

Tourismus: Fahrräder und Elektrobus auf der Top-Betonstrasse.
Nutzung der stabilen Strukturen für Windenergie-Anlagen.
Nutzung der stabilen Strukturen für Kommunikation-Sendemasten.

Waste Deposit of Megacities

Solving the Waste Problem of Megacities

The tsunami flooding barriers described in the finished project TSUNAMI form large sea reservoirs which may be used for depositing waste from mega-cities, by reducing the waste problems of coastal megacities like New York, Tokyo and Mumbay. By emptying the reservoir, covering its ground by water-impermeable clay layer and thick concrete and by building access roads for garbage trucks, the waste problem of these cities will be solved for years. After garbage and rubble filling and densification, the surface will be flattened by gravel, sand or other fine material and then covered by concrete for industry buildings and factories. Or it will be covered by soil for agriculture. The final result will be reclaiming high-value land.

LARGE-SCALE FISH FARMING

admin — Mon, 01 Mar 2021 14:18:15 +0000

Applications of Tsunami- and Flooding Barriers for Fish Farming

In addition to protecting coastlines against tsunami and storm surges by the tsunami-flooding barriers, there is the important possibility to use the large sea reservoirs between barrier and coast for large-scale fish farming.

A significant relief of the world’s nutrition problem can be achieved by using these huge reservoirs for fish farming of large fish. Overfished species like bluefin tuna could be reproduced there.The size of the reservoirs allows their division into sections for different fish sizes, to move the fractions of fish sizes from section to section, and to harvest the final size at the last section.

Gaps in the tsunami-flooding barrier, sealed by steel fences, will allow theexchange of water with each tide. Thus, always oxygen-rich sea water is available for the fish. Certaininstallation partsare produced or protected by copper alloys to prevent fouling.

All openings to the open sea can be locked by gates in case of tsunami and storm surge warning or of oil-spill warning.
