Abstract

The utility model discloses an infusion air purifier comprising a container (4) and a decontamination chamber (2), which is characterized in that the lower part of the decontamination chamber (2) is provided with a through hole (6), the middle part of the decontamination chamber (2) is equipped with an air-guide tube (3), the lower end of the air-guide tube (3) passes through and is fixedly connected with the bottom part of the container (4), the lower part of the container (4) is filled with air-filtering liquid which inundates the through hole (6) of the decontamination chamber in the stationary state. The utility model prevents the air from directly contacting with the infusing liquid, thereby effectively preventing harmful substances in the air from entering an individual body through the tube.

Description

The transfusion air purifier

Technical field:

This utility model relates to a kind of medical apparatus and instruments, especially a kind of transfusion air purifier.

Background technology:

As everyone knows, clinical transfusion all is to go up the breather of pegging graft at infusion bottle (bag) to be communicated with ambient atmosphere at present, enter by gas that bottle (bag) is interior to make liquid enter in patient's body through tube for transfusion and syringe needle, because transfusion directly contacts with atmosphere, harmful gas in the atmosphere, dust, pathogenic microorganism more easily enter in transfusion person's body, bring very important potential hazard to the patient.

The utility model content:

The purpose of this utility model is to overcome the prior art deficiency, provide a kind of atmosphere that prevents directly to contact with transfusion, effectively harmful substance enters the intravital transfusion air purifier of transfusion person in the prevention atmosphere, this utility model is realized by following technical proposals: design a liquid container and a clean room, the bottom, clean room is provided with through hole, be provided with an airway in the clean room, liquid container bottom and affixed with the liquid container bottom is passed in the airway lower end, the liquid container bottom fills the filter gas-liquid, floods clean room's through hole in static condition filter gas-liquid.

For control filter gas-liquid amount, prevent to filter gas-liquid and enter the airway upper oral part, on the wall of liquid container, be provided with liquid overflow hole.

Articulate for ease of the transfusion air purifier, can be connected with link or hook on liquid container top.

During use, the airway bottom joint and the air inlet pipe of infusion bottle (bag) are connected and add the filter gas-liquid get final product.

The conduit of this utility model clean room is with after infusion bottle (bag) air inlet pipe is connected, before transfusion, discharge the tube for transfusion air, make top, clean room and airway be negative pressure state, cause the filter gas-liquid in the liquid container to be full of the middle and lower part, clean room by clean room's lower through-hole, because this negative pressure intensity is lower and be subjected to filtering gas-liquid scale of construction restriction, when clean room's through hole exposes the filter gas-liquid surface, through hole has just become air inlet, institute advances air and fully filters through liquid, make dust, pathogenic microorganism is stranded in the filter gas-liquid, and then by top, clean room air chamber, airway enters in the infusion bottle bag clean air, from above-mentioned situation as can be known this utility model purpose can realize, compared with prior art, have the following advantages: prevented that atmosphere from directly contacting with infusing, stoped effectively that harmful substance enters in transfusion person's body in the atmosphere.

The drawing explanation:

Fig. 1 is this utility model configuration diagram;

The specific embodiment:

As shown in Figure 1, design a liquid container 4, upper opening of container is not sealed generally speaking, and said liquid container can be tank or bag, present embodiment is selected plastic bag for use, other establishes the clean room 2 of a band airway 3, and top, clean room is obturator, and the bottom is provided with through hole 6, liquid container bottom and affixed with it is passed in the airway bottom, consider anti-fluid seepage, between liquid container and airway, can set up a rubber cushion, also can being designed to one at the bottom of airway and the liquid container certainly.Present embodiment is selected airway bottom and plastic bag bottom thermal synthesis one for use, airway upper end is being good near the top, clean room, so that in running, keep it to be in the air chamber 1, in liquid container, inject filter gas-liquid 7, said filter gas-liquid can for pure water, distilled water, tap water or remove harmful gas chemical reagent solution any, injection rate is decided as required, generally the 1/4-1/3 with air chamber height height is advisable, but must flood clean room's lower through-hole, lead to the hole site is set as required generally and is advisable with 1/6-1/5 place, bottom, clean room.Too much causing filtering gas-liquid enters conduit to consider to prevent to filter the gas-liquid addition, on the liquid container wall, can have additional liquid overflow hole 5, being generally clean room's through hole is advisable about doubly to the 1-2 of container bottom distance, for ease of articulating, at liquid container oral area heat seal one link 8, an affixed certainly hook is also passable.

Claims (3)

1, a kind of transfusion air purifier, comprise liquid container (4) and a clean room (2), it is characterized in that: bottom, clean room (2) is provided with through hole (6), be provided with an airway (3) in the clean room (2), liquid container (4) bottom and affixed with liquid container (4) bottom is passed in airway (3) lower end.

2, a kind of transfusion air purifier according to claim 1, it is characterized in that: the wall of liquid container (4) is provided with liquid overflow hole (5).
