Description

DESCRIPTION

Sterilization system for beds and hospital equipment.

Field of the Invention

In sterilization and decontamination systems of hospital beds and equipment.

State of the art

Currently, in hospitals, beds and other equipment are not sufficiently sterilized or decontaminated, perhaps due to economic reasons or because they lack the necessary equipment or products for this purpose. This is more pronounced because these beds are performed on the patients many operations that are polluting by means of fluids of all kinds and this is cumulative, so the integral sterilization of these contaminated elements should be done, after each of its uses. The problem increases when these beds are displaced by the different hospital enclosures, due to the need to have to carry out complementary tests and diagnoses. The present invention solves said drawbacks.

Description of the invention

Objective of the invention and advantages

Provide a practical, economical, simple and easy to apply system that allows sterilization of beds and similar equipment, providing safe use for the remaining patients.

Problem to solve

Due to the amount of germs in hospital areas, such as those that are constantly provided by the sick and their cleanliness or treatment, it is necessary to have a constant hygiene, cleaning and sterilization, which is currently difficult to meet due to economic reasons or massification.

Sterilization is the destruction or complete elimination of all forms of microbial life. It can be carried out by physical or chemical processes (steam under pressure, dry heat, irradiation, ethylene oxide, chemical liquids).

Disinfection is a process that eliminates most or all microorganisms on inanimate objects with the exception of bacterial spores. It is done by chemical agents.

A germicide is an agent that destroys microorganisms, especially pathogens, in living tissues and inanimate objects. Depending on the germ on which it acts, it will be called fungicidal, virucidal or bactericidal.

Decontamination is defined as inactivity of the pathogenic germs of objects, so that it is safe to manipulate them.

Most used sterilization methods:

1. dry heat

2. moist heat

3. Gases: Ethylene Oxide

* Others:

4. Glutaraldehyde 2%

5. Irradiation

Both moist and dry heat sterilize, but dry heat destroys more slowly and requires higher temperatures and longer exposure times.

Dry heat sterilization: stove, dry hot air is used and the operation is performed on devices that are called hot air sterilization or stoves.

Advantages of this method: ease of installation, ease of handling and ease of being able to sterilize material inside closed containers.

Disadvantages: High temperatures are necessary, whereby the instruments to be sterilized can be damaged by excessive heat.

- No homogeneous temperature distribution.

- Excessive operating expense due to electric power consumption.

Wet heat sterilization:

Boiling water 100 ° C. It is not a sterilizing method, since it allows the survival of many spores.

Autoclave: Acts heat and pressure combined. The moist heat is produced in the form of pressurized water vapor and the mechanism of destruction is carried out through the mechanism of coagulation of the bacterial protein, destroying the most resistant microorganisms such as spores.

Ethylene oxide is an alkylating agent widely used in gas sterilization. It is active against all types of bacteria, including spores, viruses and tubercle bacilli.

It is used for all thermolabile material or that does not resist sterilization conditions by wet or dry heat. Ex .: plastics, rubber, electronic equipment.

It is mutagenic, toxic, inhalation causes nausea, vomiting and neurological disorders, like any other type of gas, it is flammable and risky when its use is not carried out properly, under controlled conditions and by competent personnel.

The sterilization system of beds and hospital equipment of the invention, consists of chambers, enclosures or rooms with irradiation systems or installations or application of heat treatment or sterilization, where the beds or devices to be sterilized are introduced and applied Mainly several sterilization modes: a) Sterilization using wet heat, b) Sterilization using dry heat, c) Sterilization using ultraviolet irradiation and d) Sterilization using ionizing gases or ethylene oxide.

Dry heat destroys with a slower speed and requires higher temperatures and longer exposure times.

Dry heat sterilization: Dry hot air is used and the operation is performed on devices that are called hot air sterilization or stoves.

Ultraviolet radiation between 100 and 400 nm can be used. Also ionizing radiation that although it is more expensive acts at greater depth.

Several of these systems can be used simultaneously and always taking into account the cost and exposure time.

Once the sterilization is finished, a sprayed deodorant can be applied.

When the beds or equipment use controls or systems of electrical or electronic control, they must be removable and sterilized separately, or they must be applied with a heat insulating cover. Otherwise, low temperature sterilization is carried out by eradication, ionization or ethylene oxide.

It may be necessary to use the beds with special materials more resistant to temperatures and some of the elements used and the control equipment and devices very easy to disassemble in order to apply less aggressive treatments.

High temperature paints or epoxy will be used in beds and other equipment.

In addition to the rooms equipped for these treatments, cameras or enclosures of reduced dimensions that can be fixed or movable and even a cover of canvas or plastic open by its lower area, which covers the bed and carrier at the edge of its lower area can be used a ring that weights and fastens the cover to the ground. Producing its isolation. It is not airtight but it is valid for some types of treatments.

More detailed description of the invention

Figure 1 shows an embodiment of the invention, with the pump or compressor (1) that blows air into the air heater (2) from where in its passage to the chamber or room (5), conditioned for said use, Injects water (3) from a tank (4). The moist and pressurized air effects the total sterilization of the bed (6). Before electro electronic devices are disassembled or thermally insulated.

Figure 2 shows the pump or compressor (1) that blows air into the air heater (2) from where it passes to the chamber or room (5) equipped for such use. Dry and hot air effects total sterilization of the bed (6). Ultraviolet rays or ionizing radiation can be used through the generators (7). Before electro electronic devices are disassembled or thermally insulated. Likewise, by means of a device, ethylene oxide gas is introduced into the chamber.

Figure 3 shows the pump or compressor (1) that blows air into the air heater (2) from where it passes to (3) where water from the tank (4) is injected. Then the hot and humid air is applied to the chamber covered with a tarp or plastic (8) and which carries the ring (9) on the lower edge that weights and holds it to the ground, preventing the escape of gases or Applied products Dry and hot air effects total sterilization of the bed (6). Likewise, by means of a device, ethylene oxide gas, ultraviolet rays or ionizing radiation can be introduced.
