Description

Transfusion defecator

Technical field

This utility model relates to technical field of medical equipment, particularly relates to a kind of transfusion defecator.

Background technology

Transfusion, blood transfusion or the conveying etc. of nutrient substance are the passages setting up between vein and medicinal liquid by transfusion device, be treatment of diseases compared with frequently with a kind of method. During use, the liquid in infusion bottle, under the effect of atmospheric pressure, flows into infusion tube in bottle and flows into vein sustainedly and stably by transfusion device, supplement medicinal liquid, blood for human body or provide nutrient substance.

In infusion process, owing to partially liq is carried after powdery type medicine dissolution, there is the little microgranule of slightly solubility unavoidably, patient may be brought danger by the existence of little microgranule. It addition, before medicinal liquid is sucked transfusion device, it is necessary to scratching the vial containing medicinal liquid, in scratching process, smaller glass fragment is likely to fall in vial, and is inhaled in needle tubing by syringe needle, brings very big danger to patient.

Therefore, those skilled in the art need the transfusion defecator studying a kind of simple in construction, good filtration effect badly, in order to intercept the insoluble little microgranule in liquid.

Utility model content

Because the drawbacks described above of prior art, this practicality newly provides the transfusion device of a kind of simple in construction, good filtration effect.

For achieving the above object, this utility model provides a kind of transfusion defecator, including joint upper cover and the joint lower cover being positioned at described joint upper cover bottom, described joint covers and is provided with screw-cap, the joint of described joint upper cover and described joint lower cover is additionally provided with the first cushion rubber and the second cushion rubber, it is provided with filter membrane between described first cushion rubber and described second cushion rubber, described filter membrane offers filtering holes; Liquid flows into described joint lower cover by described filter membrane from described joint upper cover.

In some preferred implementations, the aperture of described filtering holes is 1.0-6.0 micron, percent opening more than

90%.

In some preferred implementations, the aperture of the filtering holes on described filter membrane is 5 microns.

In some preferred implementations, described filter membrane adopts nylon material.

The beneficial effects of the utility model:

Owing to being provided with filter membrane between the first cushion rubber and the second cushion rubber, insoluble little microgranule in liquid and small glass fragment can be filtered by filter membrane, ensure that the safety of infusion process, simultaneously, it is more smooth and easy that the percent opening of more than 90% ensure that liquid flows, it is ensured that the normal circulation of liquid.

Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to be fully understood from the purpose of this utility model, feature and effect.

Detailed description of the invention

As it is shown in figure 1, the present embodiment proposes a kind of transfusion defecator, including joint upper cover 1 and the joint lower cover 2 being positioned at joint upper cover 1 bottom, in order to avoid device is not contaminated, joint upper cover 1 is provided with screw-cap, when specifically applying, this screw-cap is removed from joint upper cover 1.

The joint of joint upper cover 1 and joint lower cover 2 is additionally provided with the first cushion rubber 4 and the second cushion rubber 5, is provided with filter membrane 6, filter membrane 6 offers filtering holes between the first cushion rubber 4 and the second cushion rubber 5, and liquid flows into joint lower cover 2 by filter membrane 6 from joint upper cover 1.

Owing to being provided with filter membrane between the first cushion rubber and the second cushion rubber, the insoluble little microgranule in liquid and small glass fragment can be filtered by filter membrane, it is ensured that the safety of infusion process.

The aperture of filtering holes is 1.0-6.0 micron, it is preferable that the aperture of filtering holes is 5 microns, and the percent opening of filter membrane 6 is more than 90%. It is more smooth and easy that the percent opening of more than 90% ensure that liquid flows, it is ensured that the normal circulation of liquid.

Owing to nylon has good combination property, including mar proof, chemical proofing and self lubricity, and coefficient of friction is low, it is easy to processing, and therefore, filter membrane adopts nylon material to make.

Concrete applicable cases of the present utility model is as follows:

When specifically applying, as described in Figure 4, structure 1 of the present utility model can be connected on infusion tube 2 near the side of human body, to need to flow into the medicinal liquid of human body or blood are likely to containing impurity be filtered.

As it is shown in figure 5, this structure 1 can also be connected to tee T 2, this attachment structure, be likely in medicinal liquid or blood containing impurity be filtered at the same time it can also be prevent medicinal liquid or backflow of blood, it is prevented that blood coagulation.

If shown in 6, this structure 1 can also be arranged at the front end of syringe 2, to medicinal liquid is likely to containing glass fragment or insoluble little microgranule be filtered, it is ensured that the safety of infusion process.

Certainly, structure of the present utility model can also be attached in other way, plays the effect that the particulate matter in liquid or other solid impurities are filtered.

Preferred embodiment of the present utility model described in detail above. Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work. Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
