Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in Figure 1: the blood vessel blocking device that the blood flow of the present embodiment is controlled, comprises fracture outer ring 1 to be opened/closed, can be made up of stainless steel material or plastics.Cost is low, easy to manufacture.Fracture air bag 2 is circumferentially fixedly installed inside fracture outer ring, as shown in Figure 2, described air bag comprises annular utricule 21 and is separately positioned on the male joint 23 and female joint 22 that utricule two ends can realize being tightly connected, and arranges sealing ring 24, increase sealing effectiveness between described male joint 23 and female joint 22; Male joint is cone shape, and female joint is uncovered shape, easily docks, and can realize air bag annular and be communicated with; In addition, as shown in Figure 3, described air bag 2 is the annular of closed at both ends, and balloon ends face is planar structure, is conducive to the slitless connection of fracture.Fracture outer ring 1 overlaps with the fracture site of fracture air bag 2, can realize synchronous opening and closing, also comprises the aerating device 3 be communicated with air bag; Aerating device 3 is the extruding sacculus of band control valve.Also comprise the pressure transducer 5 for measuring vascular pressure, the probe 4 of described pressure transducer is arranged at the inner side of air bag 2.
Because Ink vessel transfusing blood flow is directly related with the change of blood vessels caliber, variety classes blood vessel elasticity is different, when certain pressure implemented by air bag to blood vessel, vessel diameter starts to narrow, this pressure is vasoconstrictive threshold value, when pressure is increased to certain value, when blood vessel is completely closed, now pressure no longer changes with the extruding of squeezer, and this pressure is vasoconstrictive maximum.When the pressure that blood vessel bears is between threshold value and maximum, the change of vessel diameter and force value proportional.
This blood vessel has just started the pressure be subject to when being extruded, pressure when maximum represents that blood vessel blocks completely, and the degree that so blood vessel is blocked then can be calculated by following formula:
The percentage ratio of gained is the degree that blood flow is blocked.
Using method: blood vessel will be worked as and be inserted in outer ring, closed, close gas check valve.Operator by pinching aerating device, is filled with air with hands in air bag.When being filled with a certain amount of air and making air bag and blood vessel wall just have pressure, now pressure display unit shows a force value (being threshold value), continue by pinching aerating device, when pressure shown on pressure display unit does not change with extruding aerating device, show that blood vessel is blocked (being maximum) completely.Operator gives vascular pressure by air bag more according to actual needs, can read pressure suffered when now blood vessel is blocked, be and record force value on pressure display unit.By above formulae discovery, the degree that blood flow is blocked can be judged.
