Abstract
The utility model provides a hepatic portal vein blocking device, belonging to the technical field of medical devices; the hepatic portal vein blocking device comprises an inflating air bag, a pressure gauge and an elastic saccule, the inflating air bag is connected with one straight tube, one side of a straight tube body is provided with the pressure gauge, one end of the straight tube is connected with a soft tube, the tail end of the soft tube is connected with the elastic saccule, an arc plate attached hoop is arranged on the soft tube, a blood vessel pressure-bearing arc plate is arranged on the arc plate attached hoop. The blood vessel pressure-bearing arc plate partially surrounds the outer side of the elastic saccule, and a one-way inlet valve and a screwed air escape valve are arranged on the inflating air bag. In the hepatic portal vein blocking device, the elastic saccule is inflated to be expanded in an air pressure way, and a portal vein is arranged between the elastic saccule and the blood vessel pressure-bearing arc plate through pressure bearing of the blood vessel pressure-bearing arc plate, air pressure blocking can be carried out to the portal vein directly, the use is convenient, the operation is simple, and the hepatic portal vein blocking device is safe and reliable.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of hepatic portal vein block device.
Background technology
Liver has abundant blood for system, comprise Hepatic artery and portal vein blood supply, for reducing safety hemorrhage and the assurance operation on liver, need block into liver blood liver and flow, mostly traditionally is that Hepatic artery and portal vein are blocked simultaneously, and operation is simple for it, but its maximum shortcoming is that the hot ischemic damage of liver is obvious, the be obstructed restriction of break time of operation, this has brought the risk of certain limit to operation.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of hepatic portal vein block device is provided.
The technical solution of the utility model realizes in the following manner, this hepatic portal vein block device, its structure comprises inflates air bag, Pressure gauge and resilient bladder, the air bag of inflating is connected with a straight tube, straight tube pipe shaft one side is provided with Pressure gauge, and straight tube one end is connected with flexible pipe, and hose end is connected with resilient bladder, flexible pipe is provided with the arc plate and adheres to hoop, and the arc plate adheres to hoop and is provided with blood vessel pressure-bearing arc plate.
Blood vessel pressure-bearing arc plate portion surrounds the outside of resilient bladder.
The air bag of inflating is provided with breather cheek valve and screws gas bleeder valve.
The beneficial effect that this utility model is compared with prior art produced is:
This hepatic portal vein block device employing air pressure mode is suppressed to resilient bladder it is expanded, and the pressure-bearing of intravascular pressure-bearing arc plate is placed portal vein between resilient bladder and blood vessel pressure-bearing arc plate then, can directly carry out the air pressure blocking-up to portal vein, easy to use, simple to operate, safe and reliable.
The portal vein that this hepatic portal vein block device is only blocked liver supplies, kept the normal blood supply of Hepatic artery of liver, can not cause liver injury, utilized Hepatic artery pressure height, oxygen content height and flow is low, portal venous pressure is low, oxygen content is low and characteristics that flow is high, make the interior oxygen supply of liver constant substantially, very light or even can not cause ischemia injury to liver, because portal vein is blocked, can significantly reduce blood loss volume during the operation simultaneously, especially can be when operation according to the optimal occluding pressure of the low adjusting of patient's hypertension.
