Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

as shown in fig. 1 to 5, the present invention provides a cardiovascular dilator, comprising: gas-supply pipe 1, gasbag cover 2, first clamp ring 3, second clamp ring 4 and restriction sleeve 5, the gas outlet has been seted up on the 1 lateral wall of gas-supply pipe, 1 overcoat of gas-supply pipe has gasbag cover 2, the gas outlet is with gas- supply pipe 1 and 2 intercommunications of gasbag cover, 2 open ends of gasbag cover first clamp ring 3 and second clamp ring 4 compress tightly on the 1 outer wall of gas-supply pipe, first clamp ring 3 and second clamp ring 4 all adopt the elastic rubber material to make, there is restriction sleeve 5 in 2 overcoat of gasbag cover, the connection can be dismantled to restriction sleeve 5 relative gas-supply pipe 1, restriction sleeve 5 is used for only allowing 2 both sides of gasbag cover to swell.

In order to realize 2 drum big with gasbag cover after gasbag cover 2, gas-supply pipe 1 and restriction sleeve pipe 5 insert cardiovascular, gasbag cover 2 covers outside the gas-supply pipe 1 inserts the end, 1 other end threaded connection of gas-supply pipe has screw cap 6, screw cap 6 is fixed to connecting rod 70 one end, the other end of connecting rod 70 is fixed to a piston 71, piston 71 hugs closely with 1 inner wall of gas-supply pipe, screw cap 6 deviates from 1 one side of gas-supply pipe and is fixed with handle 8. When the air bag sleeve is inserted into the cardiovascular system, the threaded cover 6, the connecting rod 70, the piston 71 and the handle 8 are separated from the air conveying pipe 1, the pressure in the air conveying pipe 1 is low, and the air bag sleeve 2 is in a small state, so that the insertion is facilitated; after gasbag cover 2, gas-supply pipe 1 and restriction sleeve 5 inserted cardiovascular, put into piston 71 to gas-supply pipe 1 earlier, piston 71 reduces the gaseous volume in the gas-supply pipe 1 to make the pressure increase in the gas-supply pipe 1, finally swell 2 both sides of gasbag cover, the expander opens the cardiovascular, set up the gas pocket with external atmospheric pressure intercommunication on the screw cap 6, finally, screw cap 6 and gas-supply pipe 1 threaded connection, keep the state that 2 both sides of gasbag cover swell.

In order to design the restraining sleeve 5 with a simple structure, the restraining sleeve 5 includes: a conical cover 51 and two hinder piece 52, conical cover 51 lid is outside the closed end of gasbag cover 2, conical cover 51 is connected with two and hinders piece 52, two hinder piece 52 and gasbag cover 2 and hug closely, two hinder gappedly between the piece 52, two hinder and all be provided with coupling assembling 9 between piece 52 and the screw cap 6, gasbag cover 2 is two to hinder piece two clearance departments between 52 and is bloated, coupling assembling 9 is used for realizing that restriction sleeve 5 can dismantle the connection relatively gas-supply pipe 1.

In order to design the connecting assembly 9 with a simple structure, the connecting assembly 9 comprises: chucking piece 91, spring 92 and helping the briquetting 93, there is the go-between 10 at 1 external fixation of gas-supply pipe, go-between 10 supplies to hinder the piece 52 and deviates from the tip of conical cover 51 and inserts, chucking piece 91 one end stretches into to hindering in the piece 52, chucking piece 91 can hinder piece 52 relatively and radially move at gas-supply pipe 1, chucking piece 91 other end is used for the card to go into in the calorie hole that the go-between 10 inner wall was seted up, chucking piece 91 is fixed to spring 92 one end, the spring 92 other end is fixed to hindering piece 52, can keep chucking piece 91 card to go into in the calorie hole under spring 92 elasticity, chucking piece 91 is fixed to helping briquetting 93 one end, help the briquetting 93 other end to be used for hindering piece 52 from the outer play of go-between 10.

In order to facilitate the connection between the sleeve 5 and the connection ring 10 to be limited, the clamping block 91 has a triangular structure, the clamping block 91 does not prevent the blocking block 52 from being inserted into the connection ring 10, and the clamping block 91 limits the blocking block 52 from being separated from the connection ring 10. When the clamping block 91 is separated from the connecting ring 10, the pressing assisting block 93 is pressed.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
