Description

Improved perfusion apparatus connecting pipe

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to improvement formula perfusion ware connecting pipe.

Background

The blood perfusion technology is a blood purification treatment method and means for removing toxic substances, medicines and metabolic products through nonspecific adsorption of an adsorbent in an perfusion device. The composition is often combined with a hemodialyzer in series clinically, and can remove medium-large molecular toxins in the body of a chronic renal failure maintenance dialysis patient.

At present, the perfusion device is widely used clinically, but in the process of serially operating the perfusion device and the dialyzer, dialysis is interrupted manually to carry out perfusion, the continuity of a closed system of a blood path tube cannot be ensured, the operation is complicated, and high risks of blood coagulation, air embolism, blood pollution, cross infection and the like are increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an improvement formula perfusion ware connecting pipe to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an improvement formula perfusion ware connecting pipe, includes the perfusion ware body, the bottom of perfusion ware body is linked together with the one end of connecting pipe, the other end of connecting pipe is linked together with an opening on the three way connection ware, and two other openings on the three way connection ware are linked together with the one end of outer takeover and communicating pipe respectively, the other end and the blood way pipe of communicating pipe are linked together, the one end and the top of perfusion ware body of blood way pipe are linked together.

By adopting the scheme, the improved bidirectional three-way connection mode is realized, the perfusion apparatus body is not required to be removed, and only the clamp a, the clamp b and the clamp c need to be opened and closed to change the channel, so that the operation is simple, convenient and safe.

In a preferred embodiment, a clip a is provided on the connection tube.

By adopting the scheme, the communication state of the connecting pipe can be controlled through the clamp a.

In a preferred embodiment, a clip b is provided on the communication pipe.

By adopting the scheme, the communicating state of the communicating pipe can be controlled through the clamp b.

In a preferred embodiment, the blood tube is provided with a clamp c, and the clamp c is located behind the connection position of the communication tube and the blood tube.

By adopting the scheme, the communicating state of the blood path tube can be controlled through the clamp c.

Compared with the prior art, the beneficial effects of the utility model are that:

the improved perfusion apparatus connecting pipe is provided with the connecting pipe, the clamp a, the three-way connector, the external connecting pipe, the communicating pipe, the clamp b, the blood path pipe and the clamp c, so that the clinical application is wide, the flow is simplified, the operation is convenient, and the high risks of blood coagulation, air embolism, blood pollution, cross infection and the like are avoided.
