Abstract
An endarterium injury balloon device comprises an air injection needle tube, a three-way valve, a catheter, a pressure gauge and a balloon. The air injection needle tube comprises a needle tube body, a piston and a push rod. The piston is fixedly connected with one end of the push rod and mounted in the needle tube body. An outlet of the needle tube body is fixedly connected with an inlet of the three-way valve, and a first outlet of the three-way valve is connected with a joint of the pressure gauge. A second outlet of the three-way valve is connected with one end of the catheter, and the other end of the catheter is connected with an inlet of the balloon. The three-way valve is opened, the push rod is pushed, the air injection needle tube is used to inject air into the balloon, when reading of the pressure gauge reaches a rated value, the three-way valve is closed, and then the size of the balloon is exactly required by tests. Repeatability and homogeneity of a model of the endarterium injury balloon device are high, the pressure gauge is used for measuring air pressure which is accurate, and the problem of connection of the balloon, the air injection needle tube and the pressure gauge is resolved by the aid of the three-way valve. The endarterium injury balloon device can provide a more accurate animal model for researchers and certainly develops scientific research levels.
Description
Technical field
This utility model belongs to endarterium damage device, particularly endarterium damage balloon-system.
Background technology
The Along with people's growth in the living standard, the cardiovascular and cerebrovascular disease sickness rate improves day by day, so medical workers more focus on focus on the cardiovascular and cerebrovascular disease.In recent years, the people who carries out cardiovascular and cerebrovascular vessel research was more and more, and level is also more and more darker.This type of research with the zoopery mode study more, therefore, the animal model of endarterium damage is used more and more widely.
The preclinical medicine laboratory often duplicates some animal models, so that to the research that experimentizes of some disease.In the reproduction process of cardiovascular disease animal model, the especially research of angiopathy, for example atherosclerosis usually can relate to the damage of trunk inner membrance.Tunica intima is caused artificial damage, and we generally pass through the mode of operation.Bibliographical information in the past, method is not quite similar, with sacculus repeatedly the tractive method cause the many of damage, but the method has several shortcomings, the vital homogeneity that can not guarantee model copy exactly, or perhaps the degree of injury weight differs.Relax during sacculus naturalness, behind the feeding gas, the sacculus protuberance; Diameter increases, and makes balloon wall be close to blood vessel wall, repeatedly the tractive sacculus; Sacculus must cause damage to endarterium, but how many amounts of our each injecting gas differ, thereby causes sacculus protuberance degree or balloon diameter not of uniform size; Therefore, each experiment is different to the degree of injury of endarterium.
For head it off; We carried out this studying intensively and thought deeply; And develop endarterium damage balloon-system: if can control the sacculus internal gas pressure, make the sacculus internal gas pressure certain, sacculus protuberance degree also is certain so; Diameter is also just identical, and is also just the same to the tunica intima degree of injury.Therefore, we have expected Pressure gauge, measure the pressure in the sacculus through Pressure gauge, and gas pressure has just come into plain view in the sacculus like this.
This device can cause the damage of degree homogeneous to endarterium, and should use conveniently, and operation is standardized more.
The utility model content
The purpose of this utility model provides endarterium damage balloon-system, and this device uses the gas injection needle tubing to the sacculus injecting gas, through manometric registration control air pressure, thereby obtains the identical sacculus of diameter.
The technical scheme that adopts is:
Endarterium damage balloon-system comprises gas injection needle tubing, three-way valve, conduit, Pressure gauge and sacculus.
Its technical essential is:
The gas injection needle tubing comprises needle tubing body, piston and push rod.One end of piston and push rod is fixedly connected, and piston is installed in the needle tubing body.The other end of push rod is positioned at outside the inlet of needle tubing body.
The outlet of needle tubing body and the inlet of three-way valve are fixedly connected, and first outlet of three-way valve connects with manometric joint.
Second outlet of three-way valve connects with an end of conduit, and the other end of conduit connects with the sacculus inlet.
The break-make of the valve handle control three-way valve of three-way valve.
Its method for using is:
Open three-way valve, promote push rod, use gas injection needle tubing injecting gas in sacculus, when by the time manometric registration reaches rated value, close three-way valve, this moment, the size of sacculus was the required size of test.
Its advantage is:
The raising of Along with people's scientific research level, also increasingly high for the requirement of the quality of assay device, the design has noticed the characteristics of model repeatability and homogeneity, uses this sacculus better homogeneity and the repeatability of controlling models.
This device working pressure table is measured the air pressure in the sacculus, and pressure is accurate, uses three-way valve, has solved connection sacculus, gas injection needle tubing and manometric problem.So the application market of endarterium damage sacculus is very widely.
Analyze thus, in a single day this endarterium damage balloon-system is promoted, and must receive the favor and the considerable economic benefit of vast researcher.The more important thing is and to advance the progress of scientific research level for researcher provides animal model more accurately.
