Description
Technical field
This utility model relates to a kind of defecator with slow release vaporizer, especially a kind of being installed on the respirator air vent, the defecator that the waste gas that contains antibacterial, virus that can utilize the slow release mode that the patient is breathed out carries out efficiently, kills lastingly.
Background technology
Respirator is a kind of common equipment of respiratory system disease treatment, and for example, during the SARS epidemic, the daily utilization rate per capita of respirator reaches 18%～20%, reaches as high as 25%.General respirator does not have or does not use filter, the respirator of the top grade that has to adopt filter to filter when infectiousness respiratory system disease patients such as pulmonary tuberculosis use to intercept the pulmonary tuberculosis bacterium, prevents that the diffusion of pulmonary tuberculosis bacterium from causing cross infection.But the effective measures that often all do not have kill bacteria and virus in these filters.Using or changing in the process of filter, harmful pathogenic bacteria has constituted the danger that environment is caused secondary pollution.
Though can in filter, place some sterilization medicinal liquids in advance, the pathogenic bacteria that enters is killed, along with the prolongation of service time, medicinal liquid progressively volatilizees, and its concentration reduces, and drug effect is reduced gradually.Pathogenic bacteria in the filter can not be killed fully.
The utility model content
The purpose of this utility model is that lacking comparatively effectively sterilization means at the filter interior on the present respirator provides a kind of defecator with slow release vaporizer; this device can evaporate disinfectant solution and be discharged in the filter lentamente; make filter when absorption intercepts antibacterial, virus; can efficiently and act on kill bacteria, virus enduringly, to guarantee Environmental security.
The purpose of this utility model is achieved in that
A kind of defecator with slow release vaporizer is established the cartridge filter of filter element in it comprises, also comprise the slow release vaporizer that is made of housing, reservoir and slow released parts.Surface of shell is provided with air inlet and makes the inner slow release with the cartridge filter internal communication of slow release vaporizer evaporate mouth, and this slow release evaporation mouthful clip is connected on the inlet of cartridge filter.Reservoir is communicated with slow released parts, and is fixed on described enclosure interior jointly.
In use, in reservoir, put into the sterilization medicinal liquid; Slow release evaporation mouth is snapped onto on the inlet of cartridge filter, simultaneously air inlet is connected with the air vent of respirator.Sterilization medicinal liquid in the reservoir is full of the housing of slow release vaporizer gradually and mouthful is entered in the cartridge filter by the slow release evaporation under the slow evaporation of slow released parts.When the waste gas that carries disease germs of breathing out as the patient is entered in slow release vaporizer and the cartridge filter by air inlet, the steam of sterilization medicinal liquid with in the waste gas and the pathogenic bacteria, the virus that are filtered a delay that inner filter core stops kill.
In technique scheme, slow released parts can adopt the material with adsorptive liquid characteristic to make the fibre strip body, and this fibre strip body one end stretches in the described reservoir, and coiling is fixed on the described inner walls in a spiral manner.The fibre strip body that fibrous material is made has the capillary adsorption to liquid, evaporates lentamente under the effect of its exhaled air flow and discharges disinfectant solution.
For the ease of in reservoir, add the sterilization medicinal liquid by the outside, liquid injection pipe also is installed on housing, this liquid injection pipe one end penetrates housing and is communicated with described reservoir, and the other end is fixed on outside the housing, and is provided with the fluid injection interface that docks with syringe or medical liquid container outlet.Medical personnel can utilize syringe or directly the outlet of medical liquid container be docked with the fluid injection interface, input sterilization medicinal liquid.
This utility model is simple in structure, easy for installation, easy-to-use, with low cost, and have lastingly, sterilization, disinfective action efficiently.
Description of drawings
The overall structure sketch map of the preferred embodiment that Fig. 1 provides for this utility model;
Fig. 2 is the structural representation of middle slow release vaporizer embodiment illustrated in fig. 1;
Fig. 3 is the structural representation behind the installation check valve in the slow release vaporizer shown in Figure 2;
The specific embodiment
Below, also in conjunction with the accompanying drawings this utility model is described in further detail by specific embodiment.
Figure 1 shows that the overall structure sketch map of the preferred embodiment that this utility model provides.Among the figure, establish filter element 11 (in use, filter element 11 is placed in the cartridge filter 1 along the direction of arrow among the figure, its outer surface and cartridge filter 1 inwall tightening seal card) in the cartridge filter 1.
The slow release vaporizer is made of housing 2, reservoir 3 and slow released parts 4.Housing 2 is the open taper shape in bottom, and its surface is provided with air inlet 21.The uncovered of housing 2 bottoms is that slow release evaporates mouth 22.During use, adopt the mode of interference fit to snap onto on the inlet 12 of cartridge filter 1 in this slow release evaporation mouth 22, make inner and cartridge filter 1 internal communication of slow release vaporizer.
The concrete structure of slow release vaporizer is with reference to accompanying drawing 2.Among the figure, slow released parts 4 adopts cotton fibre to make strip.Reservoir 3 adopts the software plastic tube to make, and offers two holes 31 on its surface.In the end patchhole 31 with the slow released parts 4 of strip, will around the slit tightly seal coiling and together be fixed on the inside of housing 2 in a spiral manner again with reservoir 3.
In the above-described embodiments, enter respirator for preventing that the waste gas that carries disease germs that the patient breathes out from flowing backwards by air inlet 21 and the boil-off gas of the medicinal liquid that prevents to sterilize flows backwards, an end that is positioned at housing 2 at air inlet 21 is installed the check valve that stops gas to flow backwards, and its structure as shown in Figure 3.
In Fig. 3, check valve is made of valve block 5 and support 6.Valve block 5 adopts silastic material to make the disk shape, is provided with the projection 51 that is used for fixing at valve block 5 in the heart in air inlet 21.Support 6 is cross supporting frames, and its center has clamp port 61, and this support 6 is installed in the port of air inlet 21 along the direction of arrow among the figure.During installation, projection 51 is inserted in the clamp port 61.
When the waste gas of breathing out as the patient arrived, valve block 5 pressurizeds were opened to the cartridge filter direction, and when not having air-flow to arrive, valve block 5 is covering under the elastic effect on the port that air inlet 21 is positioned at housing 2 voluntarily.
