Description

Disinfection equipment for household portable medical equipment

Technical field

The present invention relates to the field of medical and health, especially family medical and health, and in particular to a disinfection device (S) for disinfecting household portable medical equipment (E).

Background technique

With the gradual improvement of living standards, people pay more attention to the health of themselves and their families. The accelerated pace of modern life and poor living habits have led to a sharp increase in the number of patients with chronic diseases. Such people often need long-term monitoring of their physical conditions. It is difficult to meet this demand completely relying on hospital resources. Most of the portable medical devices at home are convenient and practical. People can monitor their own physical conditions at any time through home devices and understand the latest developments of the disease.

There are many types of portable medical devices for home, including blood pressure monitors, blood glucose meters, electronic thermometers, hearing aids, tractors, blood oxygen saturation detectors, dialysis equipment, home ventilator systems, nasal washes, oxygen inhalers, and so on. In order to ensure the effect of using household portable medical devices, and avoid the harmful effects to the user’s health due to the contamination or growth of bacteria or other unsanitary factors during the use of household portable medical devices, portable medical devices at home, especially home For medical equipment such as ventilator systems, nasal washers, and oxygen inhalers, it is necessary to disinfect household portable medical devices after a certain period of use.

At present, the commonly used methods for disinfection of household portable medical devices include chemical disinfection, gas fumigation, and thermal disinfection.

1. Chemical disinfection method:

Chemical disinfection refers to the use of chemical disinfectants (chlorine disinfectant, 2% glutaraldehyde alkaline solution, 0.5% peroxyacetic acid solution) to act on microorganisms and pathogens to denature their proteins, lose their normal functions and die. In the chemical disinfection method, all the pipelines must be immersed in the solution, and the connecting parts must be completely disconnected. After the disinfection is completed, the disinfectant must be rinsed with sterilized distilled water.

2. Gas fumigation method:

At present, it is believed that the ethylene oxide gas killer has strong penetrating power to the articles to be disinfected, and can reach the deep part of the article to kill most pathogenic microorganisms, and has a strong antimicrobial effect. It is currently believed that ethylene oxide kills microorganisms because it can have non-specific alkylation with microorganisms' protein, DNA and RNA. Ethylene oxide sterilization can prolong the service life of instruments, but the cost will be high. Generally, medical precision instruments are sterilized with ethylene oxide.

3. Thermal disinfection method:

The mechanism of thermal disinfection is to destroy the protein, nucleic acid, cell wall and cell membrane of microorganisms, leading to their death. The basic structure of microorganisms and the enzymes closely related to the energy metabolism, nutrition, detoxification and stabilization of the internal environment of the microorganisms are all composed of protein, which destroys the protein of the microorganisms. Inhibiting the activity of one or more enzymes can lead to the death of microorganisms. Thermal disinfection is divided into dry heat and damp heat. Dry heat and damp heat have different mechanisms for the destruction of microbial proteins. Humid heat is mainly caused by the coagulation of microbial proteins, and the mechanism of dry heat inactivating microbes is oxidation. In addition, the cell walls and membranes of microorganisms are important points of heat, and heat can simultaneously inactivate the nucleic acids of microorganisms, leading to the death of microorganisms. In order to meet the disinfection standard, the ventilator pipeline and other accessories generally adopt the steam disinfection method in the wet method, and a certain high temperature and high pressure equipment is required for disinfection.

However, the above methods all have corresponding shortcomings:

Chemical disinfection: Only passive accessories can be disinfected. The ventilator cannot be completely immersed in the disinfecting liquid, so chemical disinfection cannot be used; and there are more disinfectants used each time, which is very troublesome for recycling. After cleaning, each accessory needs to be dried and dried, which takes a long time.

Gas fumigation method: The ethylene oxide sterilization process needs to include preheating, pre-humidification, vacuuming, injecting vaporized ethylene oxide to reach a predetermined concentration, maintaining the sterilization time, and removing the ethylene oxide gas in the sterilizer. Analysis to remove the residues of ethylene oxide in the sterilized items is costly and the process is very complicated, and often requires professionals to operate. Generally, it is only suitable for hospitals and not suitable for regular household use.

Thermal disinfection: special equipment for producing high-temperature and high-pressure steam is required, and the ventilator cannot withstand excessive temperature and pressure, and is not suitable for the use of household portable medical devices.

Earlier disinfection equipment was powered by dry batteries, which consumed a large amount of power and needed to be replaced frequently, which was inconvenient to use and not environmentally friendly. Later, it is switched to lithium battery power supply. This type of disinfection equipment usually includes disinfection element generator, fan, control system, lithium battery and casing. The disinfection element generator produces a certain concentration of disinfection elements, and the rotation of the fan drives the air flow to disinfect The element sterilizes household portable medical devices. However, there are also a certain concentration of household portable medical equipment inside the disinfection equipment. Long-term use will damage the components of the disinfection equipment (such as the control board), thereby shortening the service life of the disinfection equipment.
