Abstract
The utility model relates to a negative-pressure cover of mobile bed unit, comprising a bracket, a medical transparent plastic film and a filtration sterilization box. A space sealed in four-side is surrounded with the medical transparent film, the upper edge of the medical transparent plastic film closely clings to the upper edge of the bracket, the edge of the medical transparent film contacts the external of the patient bed with a gap, or an end of the medical transparent film contacts the bedcover on the patient bed, and the filtration sterilization box is connected with the upper edge of the bracket. The filtration sterilization box comprises a box with an air outlet and an air inlet in the bottom, a high efficiency air filter and a blower, wherein, the high efficiency air filter divides the box into two spaces, a space with the air outlet and the other space with the air inlet, and the blower is arranged in the inner side of the air outlet. The negative-pressure cover can suck the viruses exhaled by the patient into the box, through the filtration of the high efficiency air filter, the sterilizing lamp kills the viruses blocked in the filter, and the clean air is discharged into the ward. The utility model can effectively prevent the infection of medical personnel, and effectively prevent the virus spreading out of the ward to pollute the surrounding environment.
Description
Technical field
This utility model relates to a kind of spacer assembly that prevents respiratory tract disease to infect
Background technology
Current, severe acute respiratory syndrome (SARS) in the world more than 30 country popular, also have more than 20 province (city) that this infectious disease is arranged in China, wherein account for more than 20% of morbidity sum according to statistics with the medical personnel of contact patients.In the face of this severe situation, protection has become the task of top priority with the medical personnel of contact patients.Show that according to epidemiologic data the route of transmission of SARS virus is that the air spittle and viral aerosol are main, and SARS patient respiration or speak, the especially spittle of tracheal intubation (incisions) patient exhalation and viral aerosol are dispersed in then in the air in the ward.Medical personnel or other people enter very easily to infect in such ward.If the spittle and viral aerosol diffusion to the pollution of ward surrounding air, also very easily infect other people to the outside, ward.
Summary of the invention
The purpose of this utility model provides the spittle that a kind of patient of making breathes out and viral aerosol and does not diffuse into portable sheet negative pressure hood in the ward air.
The purpose of this utility model realizes by following proposal: be made of support, medical overlay and filtration sterilization case, described medical overlay surrounds circumferential closed upper edge and is close on the top edge of support, its lower edge is gapped to be contacted with the periphery of patient couch top, or have an end with the bed on quilt cover contact, described filtration sterilization case is connected with the support top edge.
Described filtration sterilization case is to be made of the casing that has air outlet and air inlet in the bottom, high efficiency particle air filter and blower fan, described high efficiency particle air filter is isolated into a side to casing air outlet, the opposite side air inlet is in two spaces of bottom, and described blower fan is arranged in the air outlet inboard of casing.In the described space that air inlet arranged, germicidal lamp is set.The castor of described support is the universal wheel of band stopper.Air inlet next door at described casing is provided with illuminating lamp
This utility model is owing to adopted negative pressure cover, the air spittle that the patient breathes out and viral aerosol can not be diffused in the outer ward of cover, can directly not spray to medical personnel yet, but with it with air inspiration casing, filter out through high efficiency particle air filter, the air that cleans is discharged in the ward; Owing to be provided with germicidal lamp, the virus that is blocked on the high efficiency particle air filter is killed again.Can prevent infection effectively, and prevent that effectively virus is diffused into the pollution of facing surrounding air outside the ward medical personnel.Have simultaneously and be convenient to move, sound construction is easy to sterilization, cleans the characteristics of medical overlay convenient disassembly.
Description of drawings:
Fig. 1 is of the present utility model to analyse and observe structural scheme of mechanism
The specific embodiment
With reference to Fig. 1, a cuboidal aluminium alloy post 2, its castor are the universal wheels 1 of band stopper.At the four sides of support 2 are medical overlays 3 of sealing, and its upper edge is close to the top edge of support 2, and its lower edge is lower than bed surface, contacts the periphery of bed surface with a gap, and the medical plastic film 3 of support 2 one ends is on quilt.The filtration sterilization case is on support 2, and its bottom surface closely is connected with support 2 top edges.This just constitutes the negative pressure cover of going up face closure by the medical overlay 3 at filtration sterilization case and support 2 four sides, then constitutes semi-enclosed space between medical overlay 3 and the patient couch top, and promptly air can enter in the cover from the gap on bed surface next door.The filtration sterilization case have casing 4, one ends above air outlet 10 is arranged, air inlet is arranged below the other end, high efficiency particle air filter 9 that can blocking diameter 〉=0.3 μ m particle passes through becomes two spaces to casing 4 internal insulation in the middle of casing 4.Make air outlet 10 and air inlet 6 respectively in a space.Blower fan 11 is contained in the inboard of air outlet 10.A uviol lamp 8 is arranged above air inlet 6, a light barrier 7 is arranged, between uviol lamp 8 and air inlet 6 with anti-ultraviolet calcination patient.There is lighting lamp 5 on air inlet 6 next doors at casing 4.Start blower fan 11, the air that it is discharged in the ward is to cross filterable clean air through high efficiency particle air filter 9, promptly produces negative pressure simultaneously in cover, and room air flows in cover with regard to the edge through bed surface and circulates.
