Description
Technical Field
The invention relates to the field of medical epidemic prevention instruments, in particular to a medical care channel which is arranged between a polluted area and a clean area of a hospital and is atomized, sprayed and disinfected by protective gas and disinfectant.
Background
In order to treat novel coronavirus pneumonia, atypical pneumonia (SARS), people infected with a dozen kinds of virulent infectious diseases such as highly pathogenic avian influenza A and B, and prevent the viruses from spreading through air droplets (aerosol), contact, blood, secretion, excrement, polluted clothes and the like, the conventional hospital infectious disease department is constructed according to a three-area two-channel plan, namely, two and three access controls are arranged to cut off rooms and channels such as medical offices, dressing rooms, infectious wards and the like of an infectious disease area in a physical space, a clean area, a potential pollution area and a pollution area are sequentially formed, and a medical channel and a patient channel are arranged, and are isolated and passed along different paths, so that the novel coronavirus pneumonia, the atypical pneumonia (SARS) and the people infected with highly pathogenic avian influenza A and B have great effects on effectively cutting off virus propagation paths, but the conventional medical channel belongs to architectural structural attributes, is not epidemic prevention equipment and does not have an active disinfection function, so that there are the following drawbacks:
1. the passing procedure is complex and takes long time: when entering a polluted area, medical staff need to finish more than ten wearing steps in sequence in a sealed room of the clean area close to the polluted area, wherein the wearing steps comprise wearing protective clothing, wearing a round cap, wearing a medical protective mask, wearing protective clothing, wearing examination gloves, wearing goggles, wearing isolation clothes, wearing surgical gloves, wearing a round cap, wearing surgical gloves and wearing foot covers, and after wearing, the medical staff can enter the polluted area, and the process generally takes about 20 minutes; when the patient goes out of the polluted area, a plurality of medical garbage cans and a plurality of bottled hand disinfectant are usually placed in the communicated isolated room, after the patient goes out of the polluted area, the medical personnel need to carefully take off the protective caps, protective clothes, goggles and shoe covers on the patient layer by layer, and once taking off one layer, the patient needs to disinfect the hands, so that the patient cannot carelessly lose the hands, otherwise, the patient has the risk of infection, and the whole process needs to wash hands for more than ten times and takes more than 20 minutes;
2. the safety guarantee is poor: in and out of the pollution area, medical staff need to operate strictly according to the wearing specification of the protective articles, and the pollution accident of the medical staff or the cleaning area can happen if the medical staff carelessly happens, so in order to eliminate the negligence which can happen in the wearing process of the medical staff, a plurality of hospitals are additionally provided with special post auxiliary staff in the medical channels, help and supervise the medical staff to wear and remove the protective articles, and eliminate the occurrence of the accidental infection or pollution accident;
3. medical personnel who are not suitable for wearing bubble bag formula malleation medical protective clothing are current: in order to overcome the defects of the existing medical protective clothing, the patent No. 202010154267.1 patent bubble bag type positive pressure medical protective clothing disclosed by the Chinese patent office is the best scheme for solving the problems of safety, comfort and economy (repeated use) of the existing medical protective clothing, but the existing medical care channel of a hospital is not provided with a corresponding spraying disinfection facility, so that when medical care personnel wearing the bubble bag type positive pressure medical protective clothing get out of a polluted area, the medical care personnel can not disinfect the whole body.
Because the above-mentioned limitation that exists of current medical care passageway has not only caused great work burden and misery for medical personnel, has also increased great management degree of difficulty for the epidemic prevention safety control of hospital moreover, forces the hospital to use disposable medical protective clothing now, and then causes medical rubbish to increase, and environmental pressure increases, and the expense cost is high.
Disclosure of Invention
In order to overcome the defects of the existing medical care channel in the hospital, the invention provides an intelligent medical care channel which uses protective gas and disinfectant to carry out atomization, spray and disinfection, the medical care passage not only can lead the medical care personnel to conveniently enter the polluted area from the clean area, but also can lead the medical care personnel wearing the bubble bag type positive pressure medical protective clothing to go out of the polluted area, a minitype portable oxygen tank arranged in the protective clothing is used as an air suction source, a one-way exhaust pipe of the protective clothing arranged in the channel box body is used as an expired air exhaust channel, the operation procedures of oxygen discharge of the sealed channel box body by spraying the protective gas, disinfection of medical care personnel by atomizing and spraying disinfectant, and drying of the protective clothing by spraying the protective gas can ensure that the medical care personnel wearing the bubble bag type positive pressure medical protective clothing, the disinfection work from the polluted area to the clean area is finished within 5 minutes, and the protective gas and the disinfectant used in the atomization spraying disinfection process are automatically recycled and reused by the channel system.
In order to realize the functional characteristics, the technical scheme adopted by the invention is as follows: the medical channel for atomizing, spraying and sterilizing by using protective gas and disinfectant is formed from inlet and outlet gate machines, channel box body, interval sealing isolation plate and nitrogen gas (N)2) The protective gas spraying and recycling system, the 70% -75% ethanol spraying and disinfecting and recycling system, the channel monitoring room and the intelligent control circuit system.
An inlet and outlet gate machine: the inlet gate consists of a gate main body, a gate, an infrared correlation detector, a two-dimensional code scanning and face recognition device and a voice horn; the exit gate machine comprises a gate machine main body, a gate, an infrared correlation detector, a two-dimensional code scanning and face recognition device, a voice loudspeaker, an electric respirator operation detector and a shutdown signal transmitter.
A channel box body: the device is of a sealed tunnel type structure, and is internally integrated with a atomization spraying disinfection spray nozzle, a channel lighting lamp, a working indicator lamp, a voice horn, an oxygen and ethanol content detector, an alarm, a protective clothing one-way exhaust pipe automatic contraction pipe coiling device, a protective clothing one-way exhaust pipe, a protective gas exhaust hole, a disinfectant liquid accumulation tank, a disinfectant discharge hole and the like, wherein a traffic signal lamp arranged outside a channel is green, yellow and red are forbidden; white light and the work pilot lamp of box internally mounted, the colour of work pilot lamp changes because of the operation content of difference, and light green when protective gas sprays, is light pink when ethanol antiseptic solution sprays the disinfection. Of course, the colors of the lights can be selected and combined in various ways, and the corresponding semantics of each color and the combination thereof can be defined in various ways, and the above expression is only one of them. The voice horn mainly refers to voice horns which are arranged in the inlet and outlet gate main body and the channel box body and used for sending corresponding prompt instructions to medical staff in a voice mode.
