Abstract
The utility model provides an air filtering device for a disposable blood transfusion apparatus, which comprises a step-typed air filtering device cover in the cavity and an air filtering device plug matched with the inlet of the air filtering device cover. The air filtering device has the advantages that the structure is simple, the operation is convenient, and the overflowing of medical liquid can be avoided, the filtrating area is large, and the smooth blood transfusion and liquid transfusion is ensured. The air filtering device is suitable for transfusion with large package such as rigid package, semi-rigid package or soft packaging, and also can be used in the identical transfusion.
Description
Technical field
This utility model relates to a kind of filter, particularly relates to a kind of disposable blood transfusion and infusion device air filter that is used on the medical apparatus and instruments.
Background technology
Disposable blood transfusion and infusion device uses very general, and the air filter that is mated generally is divided into two kinds.The first is made up of air filter cover; It two is made up of air filter cover and the air filtration plug that is mated.During use, all be the perforator air flue inwall that filter membrane is positioned over the blood transfusion and infusion device, air filter cover filled in perforator air flue inwall again, the air filter plug is a cylindrical shape, blocks filter membrane.The former, because no air filter plug, filter membrane exposes outside, when being used for soft disposable blood transfusion and infusion device and carrying out infusion solutions, overflows medicinal liquid at the air filter place easily, causes pollution, thereby increases the weight of the state of an illness.Though the latter is added with the air filter plug, but because filter membrane is to be positioned in the perforator air intake duct of disposable blood transfusion and infusion device, and the size of perforator air intake duct is less, adding air filter cover is interior the plug in the perforator air intake duct, therefore air duct is very narrow, and when amount of infusion was big, filter membrane easily stopped up, thereby cause that transfusion is not smooth, can not satisfy actual instructions for use.Moreover, because filter membrane is to be positioned in the perforator of disposable blood transfusion and infusion device, to assemble very difficultly, efficient is low, might occur assembling undesirable situation, thereby cause product not meet standard.
Summary of the invention
The purpose of utility model is to overcome above-mentioned shortcoming, and a kind of overflow of drug fluid of avoiding is provided, and filter area is big, can guarantee the disposable blood transfusion and infusion device air filter that the blood transfusion and infusion process is unobstructed.
The air filter plug that the disposable blood transfusion and infusion device of this utility model comprises air filter cover, cooperates with air filter cover with air filter.Wherein, air filter cover is a cylindrical shape, and inner chamber is a step, is used to place filter membrane, and its arrival end cooperates with the air filter plug.Be processing, easy to use, air filter plug and air filter cover are an overall structure.
The disposable blood transfusion and infusion device of this utility model with the operation principle of air filter is, during use, earlier filter membrane is positioned over the air filter cover cavity, again the air filter cover port of export is enclosed within on the perforator air intake duct of disposable blood transfusion and infusion device outward, and fix with it, or pass through the air filter seat and flexible pipe is connected with the perforator air intake duct of disposable blood transfusion and infusion device with welding or agglutinating mode.An end that is about to flexible pipe is connected with the perforator air intake duct, and the other end is connected with air filtration seat one end, and the air filtration seat other end cooperates with the air filter cover cavity.When being used for the transfusion of hard or semi-rigid container, open the air filter plug, air enters container after filtering through filter, gets final product blood transfusion and infusion; When being used for the flexible container infusion solutions, then close the air filter plug, make it to become the blood transfusion and infusion system of sealing, rely on atmospheric pressure and medicinal liquid deadweight transfusion.
The disposable blood transfusion and infusion device of this utility model is simple in structure, easy to use with the advantage of air filter, can avoid overflow of drug fluid, and filter area is big, can guarantee that the blood transfusion and infusion process is unobstructed, and can use in the homogeneous blood transfusion and infusion.The disposable blood transfusion and infusion device that is suitable for hard, semi-rigid and soft material uses.

The specific embodiment
The disposable blood transfusion and infusion device of this utility model comprises air filter cover 1, the air filter plug 2 that cooperates with air filter cover 1 arrival end with air filter.During use on the outer air intake duct that is enclosed within perforator 3 of air filter cover 1 (Fig. 2); Or be connected (Fig. 3) with the air intake duct of perforator 3 by air filter seat 4 and flexible pipe 5.
Claims (2)
1, a kind of disposable blood transfusion and infusion device air filter comprises air filter cover and the air filter plug that cooperates with the air filter cover arrival end, it is characterized in that the air filter cover cavity is a step.
2, want 1 described disposable blood transfusion and infusion device air filter as right, it is characterized in that air filtration plug and air filtration lid is an overall structure.
