Description

Bleeding volume monitoring and blood collection feedback device in interventional operation

Technical Field

The application relates to the field of medical equipment, in particular to a bleeding amount monitoring and blood collecting and feedback device in interventional operation.

Background

The blood collection and reinfusion device in the operation that is used clinically at present is mainly applicable to traditional open operation, and the bleeding often gathers in human tissue low-lying cavity way position in the art, mixes together with various tissue fluids in the body, tissue piece, fat grain etc. need to rely on negative pressure aspirator to suck, then collects in the container. If bleeding is less, the liquid is directly discarded; if bleeding is more, the mixture with blood is filtered and purified by a strict procedure by utilizing a plurality of complex filtering devices and then is returned to the patient, so that the risk of infectious diseases caused by operation blood loss and transfusion donation blood sources is reduced.

In recent years, interventional operations have been gradually carried out, and for vascular related interventional operations, various instruments are carried out through a catheter port, and when the catheter port is opened, blood flows out through the catheter port due to the pressure of a blood vessel, negative pressure suction is not needed, and the blood can flow out by itself, so that the blood is easy to collect. The outflow blood is often mixed with contrast agent, isotonic normal saline and the like, has no other impurities, has few thrombus due to heparinization anticoagulation, and can be directly returned after collection without strict filtration and purification; for example, when the pericardium is tamponade during the cardiac intervention, the blood pumped by the pericardium puncture can be directly collected and then returned into the blood vessel through veins.

In the conventional interventional operation, due to small wound and small bleeding, for blood flowing out through a catheter, an operator generally adsorbs the blood by using gauze and then discards the blood, and the bleeding amount is not accurately measured. Along with the development of interventional technology, the current condition of a patient undergoing interventional therapy is more and more serious, and the complexity of interventional operation is also more and more advanced.

For special operations with heavy illness, long operation time, large operation difficulty or thicker catheter and smaller patient weight adopted in interventional operation, the bleeding amount of the patient is inconvenient to monitor, and even if the bleeding amount is large, the bleeding amount is easily ignored, so that serious clinical consequences are caused; because of the inconvenience of collecting lost blood from the patient, when the amount of bleeding is large, the transfusion blood bank donates blood, which increases hospitalization costs and the risk of infection with blood-borne infectious diseases. In addition, currently in the interventional procedure, surgical assistants are required to clamp and fix the catheter and the guide wire by using forceps, so that not only is the number of surgical assistants required, but also the interventional radiation has adverse effects on the surgical assistants.
