Abstract
The utility model relates to an air filter used for perfusion devices, which comprises an upper shell, a lower shell and a filter membrane purifying layer. The filter membrane purifying layer is clamped between the upper shell and the lower shell; a ring convex is arranged on the outer surface of the mesh-operculiform upper shell; a ring concave is arranged on the inner surface of the infundibulate low shell; the upper shell and the lower shell are connected and fixed together cooperating with each other. The utility model overcomes the shortcomings of prior upper shell and lower shell stuck and connected together by manual adhesives; the utility model has a low production cost and a good filtration and seal. With a simple structure, a reliable connection and a beautiful appearance, the utility model is an ideal air filter used for matching with perfusion devices.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of transfusion device air filter.
Background technology
We know that transfusion, blood exchange transfusion set are the medical apparatus and instruments of using always.In air, microgranule and pathogenic microorganism that all size that is scattered here and there does not wait, as tubercule bacillus, Diplococcus pneumoniae, influenza virus, poliomyelitis pathogenic bacteria etc., these pathogenic microorganisms are mostly attached to than on its various grits surface more than the big several times, can in air, survive a period of time, in the clinical vein infusion process, air in the ward enters in the infusion vessel by air inlet pipe, like this, microgranule and pathogenic microorganism with the air admission medicinal liquid are polluted medicinal liquid, it enters into human body, will produce harm to human body.At present, in clinical vein transfusion, blood transfusion,, use supporting with it air filter by the national standard requirement.Existing filter generally is made up of upper and lower casing and filter membrane purifying layer, and the filter membrane purifying layer is clipped between the upper and lower casing, and the air that enters medicinal liquid is filtered, purifies.Because upper and lower shell body structure and is connected rationally inadequately adopts gluing connecing, hand-manipulated processing more; The filter membrane purifying layer of selecting for use is more complicated also, makes existing air filter cost height, filters, clean-up effect is bad.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and production cost is low, the transfusion device air filter of filtration, good purification.
The technical scheme in the invention for solving the above technical problem is: a kind of transfusion device air filter, it comprises upper shell, lower house and filter membrane purifying layer, the filter membrane purifying layer is clipped between upper shell and the lower house, it is characterized in that: square shape upper shell outer surface is provided with annular protrusion, infundibulate lower house inner surface is provided with annular groove, and upper shell and lower house tight fit engagement connection are fixed.
This utility model since upper shell and lower house to adopt tight fit to be fastened and connected fixing, against existing technologies, it has overcome the deficiency of the bonding assembling of manual gluing in the past, production cost is low, filters and good sealing effect.This utility model is simple in structure, connects reliable, attractive in appearance.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified:
Fig. 1 is a structural representation of the present utility model.
1. upper shells among the figure, 2. lower house, 3. filter membrane purifying layer, 4. annular protrusion, 5. annular groove.
The specific embodiment
As can be seen from Figure 1, a kind of transfusion device air filter of this utility model, it comprises upper shell 1, lower house 2 and filter membrane purifying layer 3.Upper shell 1, lower house 2 adopt the non-toxic plastic processing and fabricating.This utility model upper shell 1 is a square shape, is provided with some air inlets above it, and air is from entering here.Lower house 2 is an infundibulate, and its underpart is provided with a pipe joint, is used for being connected with the transfusion device air intake duct.Filter membrane purifying layer 3 is a glass fibre membrane, and it is clipped between upper shell 1 and the lower house 2.Glass fibre membrane is done the filter membrane purifying layer, and cost is low, and is effective.Above-mentioned composition be connected with prior art basic identically, do not describing in detail.
Characteristics of the present utility model are to improve on upper shell 1 and lower house 2 axial engagement faces.Wherein, square shape upper shell 1 outer surface is provided with annular protrusion 4, and infundibulate lower house 2 inner surfacies are provided with annular groove 5, and the two cooperatively interacts, and upper shell 1 and lower house 2 tight fit engagement connections are fixed.Like this, just overcome the deficiency of past upper shell 1 and the bonding assembling processing of lower house 2 manual gluings, be convenient to carry out automated production.
This utility model is simple in structure, connects reliably, attractive in appearance, and its production cost is low, filters and good sealing effect.
