Suspended retransfusion set

Abstract

The invention discloses a suspended retransfusion set, and belongs to the technical field of medical equipment and supplies. A clinical washing type autotransfusion technology has allogeneic transfusion shortcomings and plasma protein and coagulation factor loss; a simple method of manual filtering operation by multiple operators is frequently adopted for the conventional filtering type autotransfusion technology, and is exposed and high in pollution rate. The suspended retransfusion set consists of a negative-pressure suction pipeline, a blood recovery pipeline, a retransfusion pipeline and an automatic anticoagulant transfusion device, wherein the negative-pressure suction pipeline consists of a negative-pressure pipe, a negative-pressure conversion bottle, a negative-pressure indicator and a regulator, and is communicated with an upper filter screen gap through an internal opening of the negative-pressure pipe; the blood recovery pipeline comprises a suction head, a blood inlet pipe, a coarse filter screen, a fine filter screen, the upper filter screen gap, a blood storage tank, a blood storage tank air inlet pipe, a blood transfusion three-way valve and the like; the automatic anticoagulant transfusion device comprises a medicine storage tank, a medicine transfusion pipe, a medicine transfusion pipe grading valve, a blood inlet pipe-medicine transfusion pipe synchronization valve and the like. The suspended retransfusion set has the advantages of integrated design, automatic anticoagulant transfusion function, high recovered blood quality, high operability, high emergent treatment performance and the like.

Description

Technical field [0001] The invention relates to a medical device, in particular to emergency operations such as massive hemorrhage in the thoracoabdominal cavity, hemorrhagic shock, etc. , Autologous blood reinfusion device for blood reinfusion in elective clinical surgery. Background technique [0002] As my country gradually enters into an aging society, new and difficult surgical operations continue to be carried out, and the number of operations increases, the problem of clinical blood shortage becomes more prominent. In recent years, the autologous blood reinfusion technology has been highly praised by the medical circles of western countries [1] Wide application in the field of surgery [2，3] , is one of the effective measures to relieve blood tension. In foreign advanced hospitals, the autologous blood transfusion rate accounts for more than 50%, and the domestic gap is relatively large. [4] Compared with allogeneic blood transfusion, autologous blood reinfusion te...

AI Technical Summary

Problems solved by technology

[0005] Existing filtered blood transfusion devices have defects such as scattered, loose, impractical design, additional manpower or manual assistance, and no automatic anticoagulant infusion device; most hospitals still use the filtered blood transfusion technology Simple method, the steps are: recover the blood and mix it with anticoagulant, filter it with 8-10 layers of sterile gauze built into the blood transfusion funnel, and then filter it through the 40-60μm filter of the blood transfusion set before infusing it to the patient

[17，18] The recycling operation of this method is cumbersome and requires the cooperation of multiple people, and the exposure operation is easy to cause pollution
