Blood volume controllable vessel occlusion device

Abstract

The invention discloses a blood volume controllable vessel occlusion device. The blood volume controllable vessel occlusion device comprises a fracture outer ring and an air charging device, wherein the fracture outer ring can be opened and closed, a fracture air bag is fixedly arranged on the inner side of the fracture outer ring along the peripheral direction, the fracture positions of the fracture outer ring and the fracture air bag coincide to achieve simultaneous opening and closing, and the air charging device is communicated with the air bag. An operator can pressurize a blood vessel through the air bag according to practical need, and the pressure borne by the vessel at the time when the vessel is occluded, namely, the measured pressure value, can be read on a pressure display device, so as to judge the degree, by which the blood flow is occluded. By adopting the vessel occlusion device, not only can the blood flow occlusion to any degree be achieved according to practical need in an operation so as to more accurately and more intuitively measure the blood flow occlusion conditions for the blood vessels at different thicknesses and types, but also the blood flow occlusion manner is less in injury on the blood vessel to achieve the reversible operation on increasing and reducing the blood flow amount so as to facilitate the blood flow detection relevant assay or treatment control.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood vessel blocker capable of controlling blood flow according to actual needs. Background technique [0002] In medical research, it is often necessary to observe the effects of different degrees of ischemia on the function of its blood supply tissue and organs, but for a long time there has been a lack of instruments that can flexibly control blood flow in blood vessels according to actual needs. In traditional research, medical research Patients usually block the blood flow through surgical thread ligation or injection of embolism. Both of the above two methods have serious shortcomings: surgical thread ligation can only achieve the purpose of completely blocking blood vessels, and cannot observe the impact of different degrees of ischemia on tissues and organs; and the way of injecting embolic agents is difficult to control the blockage of embolic agents on blood vessels The degree al...

[0002] In medical research, it is often necessary to observe the effects of different degrees of ischemia on the function of its blood supply tissue and organs, but for a long time there has been a lack of instruments that can flexibly control blood flow in blood vessels according to actual needs. In traditional research, medical research Patients usually block blood flow through surgical thread ligation or injection of embolism

Both of the above two methods have serious shortcomings: surgical thread ligation can only achieve the purpose of completely blocking blood vessels, and cannot observe the impact of different degrees of ischemia on tissues and organs; and the way of injecting embolic agents is difficult to control the blockage of embolic agents on blood vessels degree, which also makes the degree of ischemia difficult to control

Therefore, the current research on the effects of different degrees of ischemia on tissues and organs generally adopts the method of complete blockage, that is, the method of completely cutting off the blood flow. observation

Moreover, the blockage of blood flow by these methods is irreversible, and it is difficult to observe the functional changes of tissues and organs after blood flow reperfusion
