A device for recording blood flow during simulated surgery

Abstract

The invention discloses a device for recording blood flow in a simulated operation. The device comprises a three-channel cock valve, a syringe, a needle type communicating vessel, a venous indwelling needle, a small injector, a measuring tube and a PE tube. The three ends of the three-channel cock valve are connected with the PE tube, the small injector and the syringe respectively, the other end of the syringe is connected with the needle type communicating vessel, and the needle type communicating vessel is externally connected with the venous indwelling needle. The measuring tube is arranged below the venous indwelling needle. The device is easy to manufacture, low in cost and high in precision, blood coagulation cannot occur in the measuring process, and the device is suitable for various medical colleges and research institutions to study medicine and other intervention means, and is easy to popularize.

Description

Technical field [0001] The invention relates to a device for recording bleeding flow, in particular to a device for recording bleeding flow during a simulated operation. Background technique [0002] Bleeding is inevitable during surgery, and a large amount of bleeding can endanger the life of the patient and affect the prognosis. In order to reduce the amount of bleeding, the application of controlled blood pressure reduction technology has been paid more attention. However, there are few methods to calculate the amount of bleeding in the study. The classic method is to use dry gauze to suck blood and then weigh for calculation. This method is a rough estimate in surgery. However, it is used to study the intervention effect of certain drugs or technologies on the amount of bleeding, and its accuracy is poor, especially when studying the amount of bleeding during the intervention of a certain drug in a certain period of time, the accuracy is relatively coarse. And there is no ot...

Problems solved by technology

In order to reduce the amount of bleeding, the application of controlled blood pressure reduction technology has been paid attention to. However, there are few methods for calculating the amount of blood loss in the research. The classic method is to use dry gauze to absorb blood and then weigh it to calculate. This method can be used for rough estimation during surgery. However, when used to study the intervention effect of certain drugs or techniques on bleeding volume, its accuracy is poor, especially when studying the bleeding volume of a certain drug during a certain period of time, the accuracy is relatively rough.
