Intelligent femoral artery pressure hemostat

Abstract

The invention discloses an intelligent femoral artery pressure hemostat and relates to the technical field of medical instruments. The intelligent femoral artery pressure hemostat is mainly used for compression hemostasis after a femoral artery puncture and intubation operation. The technical proposal of the invention is to provide a full-automatic, intelligent, and mechanical finger pressing device, which can completely simulate the compression hemostasis movement of human fingers. The technical proposal of the invention comprises four parts: I, a mechanical structure system provides a framework and components for mechanical action ; II, a mechanical power system facilitates movements of lifting, advancing, retreating and locking; III, a monitoring system is used for monitoring a pulse signal of a femoral artery as well as feeding back the pulse signal to a control system and interacting with the control system; and IV, an intelligent control system applies the microcomputer technology, is provided with special softwares which are capable of receiving and processing the pulse signal, as well as analyzing and memorizing the strength of the pulse signal, and is linked with the mechanical power system to realize femoral artery searching and locking, and setting of the pressure size and time to the femoral artery.

Description

technical field [0001] The patent of the present invention relates to the production of a medical device, in particular to the production of a medical device for femoral artery compression and hemostasis after femoral artery puncture and catheterization in interventional radiation. Background technique [0002] Femoral artery puncture and cannulation is the basic operation of most endovascular interventional procedures. After the operation, the puncture site must be hemostasis. The traditional method is to use fingers to press the femoral artery at the puncture point for 10-15 minutes. This kind of boring work not only consumes the energy of the operator, but also takes up the precious time of the operator and the operating table. Therefore, clinically, there has long been a desire to liberate this labor. In 1993, I tried to use the airbag bandage to wrap the groin, and pressurized the airbag in order to achieve the purpose of replacing artificial finger pressure to stop bl...

AI Technical Summary

Problems solved by technology

In 1993, I tried to apply the airbag bandage to the groin, and pressurized the airbag in order to achieve the purpose of replacing artificial finger pressure hemostasis, but I gave up the actual use because it was not safe and reliable.

Later on, there are also people who have developed various mechanical compression methods with airbags or screw rods to try, (there are dozens of such utility model patents that can be searched on the Internet), but these methods are not very safe and reliable, and It also requires manual operation

Foreign research on this mostly focuses on the occlusion and closure of the femoral artery puncture point with special interventional instruments, such as Angio-Seal occluder, Proglide suturing device, Starclose occluder, etc., but these methods must be performed by experienced physicians. It is not an ideal solution to do it yourself, and it is expensive, and after all, there are suture foreign objects in the body.
