Description
Technical field
This utility model relates to a kind of operation on heart medical treatment consumptive materials, is specifically related to a kind of cardiotomy suction pipe conduit.
Background technology
In cardiac surgical procedure, need to carry out negative pressure by a suction catheter to endocardial to suck blood, suck blood in process due to negative pressure and there is certain absorption affinity, therefore there is situation endocardium being adsorbed on mouth of sucking blood, the mouth of pipe now namely can be caused to block, need to stop hands art, carry out the adjustment of suction catheter, operating time now will be caused to increase, the harm that operation risk promotes, the endocardium of damage can have a strong impact on postoperative cardiac function, simultaneously because opening suction catheter being imported endocardial only has 3 ~ 6mm, how to realize the importing of suction catheter, endocardium can not be caused in negative pressure sucks blood process to adsorb simultaneously, it is the application's problem to be solved.
Utility model content
The purpose of this utility model is for above-mentioned Problems existing and deficiency, provides a kind of reasonable in design, can effectively prevent endocardium from being adsorbed the cardiotomy suction pipe conduit resulted in blockage.
For achieving the above object, the technical scheme taked is:
A kind of cardiotomy suction pipe conduit, comprise suction catheter body, the attraction joint being arranged on suction catheter body outer end and the hole of sucking blood be opened on suction catheter body inner end tube wall, described suction catheter body inner end is also provided with anti-adsorbing mechanism, described anti-adsorbing mechanism comprises the top cap being arranged on suction catheter body inner end termination, with top cap link together and circumferentially uniform stay, be arranged on the throw-out collar of the stay other end, and the guide wire be movably set in the tube wall of suction catheter body, described guide wire inner end is connected with throw-out collar, the outer end of guide wire is extended suction catheter tube wall and is provided with push-and-pull head.
The tube wall of described suction catheter body offers respectively and the strip groove of stay and throw-out collar Corresponding matching and annular groove, described hole of sucking blood is opened in strip groove.
On described top cap, the uniform stay quantity that is provided with is 3 or 4.
Adopt technique scheme, acquired beneficial effect is:
This utility model reasonable in design, it can design on the basis of original caliber, make after cardiac procedure sent into by suction catheter, cover can be strutted in mouth place formation of sucking blood, be placed in spacious for side opening of sucking blood in the wide space that struts in cover, prevent endocardium from being adsorbed, block mouth of sucking blood, effectively can avoid the generation of uncertain factor, reduce the persistent period of operation, improve the success rate of operation and the recovery of postoperative cardiac function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of suction catheter body inner end.
Fig. 3 is the structural representation of anti-adsorbing mechanism.
Fig. 4 is anti-adsorbing mechanism expanding structure schematic diagram.
Sequence number in figure: 1 be suction catheter body, 2 for attracting joint, 3 to be hole of sucking blood, 4 for top cap, 5 be stay, 6 be throw-out collar, 7 be guide wire, 8 be push-and-pull head, 9 be strip groove, 10 for annular groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
See Fig. 1-Fig. 4, a kind of cardiotomy suction pipe of this utility model conduit, comprise suction catheter body 1, the attraction joint 2 being arranged on suction catheter body 1 outer end and the hole 3 of sucking blood be opened on suction catheter body 1 inner end tube wall, described suction catheter body 1 inner end is also provided with anti-adsorbing mechanism, described anti-adsorbing mechanism comprises the top cap 4 being arranged on suction catheter body 1 inner end termination, with top cap 4 link together and circumferentially uniform stay 5, be arranged on the throw-out collar 6 of stay 5 other end, and the guide wire 7 be movably set in the tube wall of suction catheter body 1, described guide wire 7 inner end is connected with throw-out collar 6, the outer end of guide wire 7 is extended suction catheter tube wall and is provided with push-and-pull 8.
The tube wall of described suction catheter body 1 offers respectively and the strip groove 9 of stay 5 and throw-out collar 6 Corresponding matching and annular groove 10, described hole 3 of sucking blood is opened in strip groove 9, and on described top cap 4, uniform stay 5 quantity that is provided with is 3 or 4.
This utility model reasonable in design, it can design on the basis of original caliber, make after cardiac procedure sent into by suction catheter, cover can be strutted in mouth place formation of sucking blood, be placed in spacious for side opening of sucking blood in the wide space that struts in cover, prevent endocardium from being adsorbed, block mouth of sucking blood, effectively can avoid the generation of uncertain factor, reduce the persistent period of operation, improve the success rate of operation and the recovery of postoperative cardiac function.
