Description
Technical field
This utility model relates to a kind of health-care medical equipment, is specifically related to a kind of bed that meets the two stage biological safety criterion, and the treatment that can be used as the deadly infectious disease people prevents that with bed medical personnel are infected, also can be used for carrying out the bio-safety experiment.
Background technology
The gas of some deadly infectious disease patients' Excreta, secretions, exhalation, and the needle point used to patient injection in all may contain a large amount of pathogen, many materials can form aerosol, patient's " spittle " of coughing and forming particularly, in the operating process such as medical personnel give patient's expectoration, make the bed, spreading of pathogen very easily taken place.From the end of the year 2002 begin to take place and in several megalopolis the dirty inflammation of popular in succession atypia (SARS), just caused medical personnel, infected in a large number at short notice with lesion patient, families of patients, dead behind the part medical staff infection.
Reducing the danger of infection, a kind ofly think comparatively effective and efficient manner at present, is to adopt negative pressure device in the ward, note air filtration and Temperature and Humidity Control in the ward simultaneously, to purify the air in the ward, reduce aerocolloidal gathering, reduce the probability of droplet transmission.
Yet, the cost of this mode is quite expensive, at present, development one cover comprises surplus the laminar flow negative pressure operating room cost about 100 in medical worker operating room (toilet), surge chamber (Semi-Contaminated Zone), ward (high pollution district) ten thousand yuans, and several wards of limited quantity only can be equipped in this ward expensive, high operating cost in the minority large hospital.
When we run into the situation of deadly infectious disease (as SARS) outburst, must adopt other feasible mode, reduce the propagation risk, guarantee medical personnel's safety.
Summary of the invention
It is safety bed that this utility model purpose provides a kind of two stage biological, and the control by to the local environment of bed reaches the two stage biological safety criterion.In this process, need the problem of solution, the one, this class patient can be accompanied by hyperpyrexia usually, and the wind that directly blows to patient can influence patient's health; The 2nd, avoid producing bigger noise, so that patient to be provided rest environment preferably.
For achieving the above object, the technical solution adopted in the utility model is: a kind of two stage biological is safety bed, comprise bedstead, bed board, described bedstead is an enclosed construction, the top is provided with the air inlet of band filter, bed board is positioned at the middle and lower part of bedstead, the bed board top is for using the district, the below is a scavenge duct, bed board is provided with side sheet room and is communicated with the air guide port that uses district and scavenge duct, one end of scavenge duct is communicated with air interchanger through corrugated tube, uses at least one side plate of distinguishing to be provided with the door that moves of liftable folding.
In the technique scheme, described enclosed " bedstead " can by be positioned at four jiaos supporting steel pipe, seal each face color steel, connect steel pipe and constitute, castor or damping spring can be installed in the bottom; Described " air inlet " forms for perforate on the color steel of end face, only needs to install roughing efficiency air filter in the ordinary course of things in the air inlet; During use, air interchanger is outwards bled, air is through the air inlet at bedstead top, use the district by entering after the filter filtration, and enter scavenge duct through the air guide port of a side, after corrugated tube enters air interchanger, discharge again, filter or other treatment facilities can be installed in the air interchanger, with the aerocolloidal gaseous contamination environment of avoiding discharging that carries the germs of a disease.
Further technical scheme can respectively be provided with the door that moves of a liftable folding, the described transparent door that moves that moves door for the glass formation on two long side plates of bedstead.Like this, open the door in left side or right side as required.
In the technique scheme, described transparent move the door can be electronic, also can be manual.Usually, can adopt the mode of steel wire counterweight to come balance to move the weight of door, be convenient to move door and move up and down, thereby, only need the low power motor of configuration can be so that to move door electronic, certainly, it is more convenient that electronic and manual two kinds of handle structure meeting is set simultaneously.
Owing to open the door in both sides, for reaching ventilation effect preferably, require air guide port to be positioned at a side of not opening the door, its a solution is that by three sliding slot boards supports, the width of bed board is less than the width of bedstead respectively for described bed board two ends and central authorities, can slide along sliding slot board, near a side side plate, constitute air guide port with the interpleural elongated opening of opposite side during the bed board location, the scavenge duct below is provided with roughing efficiency air filter.Thereby, bed board is moved to a side of opening the door, opposite side is an air guide port, can guarantee the proper flow of air-flow.
Another kind of solution is, the width of described bed board is less than the width of bedstead, the rectangular air guide port of bed board lateral symmetry, and air guide port is provided with turnover sideboard, and the air guide port below is provided with roughing efficiency air filter.At this moment, can be provided with the interlinked mechanism that is made of spring, hoist cable and gear at described sideboard and between with the sidesway door, when moving door when being in open position, sideboard covers air guide port.Thereby automatic conversion air guide port.
In the technique scheme, the filter in the described air inlet can be made of roughing efficiency air filter and high efficiency particulate air filter two-stage.This structure is suitable for offering critically ill patient and uses.
In the technique scheme, described air interchanger is by housing and be installed on the intravital blower fan of shell, high efficiency particulate air filter constitutes, and the air inlet of blower fan is connected with corrugated tube, and the gas outlet is communicated with escape pipe through high efficiency particulate air filter.It is outdoor that the opposite side discharge can directly be led in the gas outlet, also can upwards be connected with air flue.
For the vibration that reduces a body and the noise of generation thereof, can in the supporting steel pipe of described bedstead, place lead.
In the technique scheme, can on the inwall of the seam in air channel and bedstead, be provided with the sound-absorbing sponge.
Because the technique scheme utilization, this utility model compared with prior art has following advantage:
1. this utility model provides a zone of negaive pressure fluid space in the bedstead scope, and is provided with the multiple filtration structure, can use for treatment deadly infectious disease people, avoid medical personnel to be infected, and cost is far below setting up negative pressure laminar flow operating room;
2. this utility model adopts the top air inlet, at the bed board side air guide hole is set, thereby air-flow can directly not blow to the people on the bed board, helps patient's rehabilitation;
3. this utility model separates setting with air interchanger with bedstead, connects by corrugated tube, thereby has greatly reduced bed vibration of body and importing into of noise;
4. in the preferred version of the present utility model, the seam in the air channel is provided with the sound-absorbing sponge, can reduce noise effectively.
