Abstract
A kind of cardioplegic solution reverse perfusion pipe, is related to the field of medical instrument technology.The cardioplegic solution reverse perfusion pipe is made of tube body 1, sacculus 2；Tube body 1 is hollow siphunculus, is divided into three parts: extension, middle section, pipe body part；The extension and middle section are furnished with liquid drain hole；Sacculus 2 is the deformable full hollow ball for being furnished with tiny liquid drain hole, is fixed on the outside of 1 middle section of tube body in one end protrusion one end recess；The fixed point of the sacculus 2 is located at the intersection of middle section and extension and pipe body part, and pipe shaft 1,2 fixed form of sacculus are to be integrally formed or be bonded.When in use based on cardioplegic solution reverse perfusion pipe of the present invention, patient vessel is damaged without having to worry about hard head end in art, meanwhile, insertion process is more smooth.
Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of cardioplegic solution reverse perfusion pipe.
Background technique
Cardioplegic solution reverse perfusion pipe is the important accessory of cardiopulmonary bypass surgery, it acts as by cardioplegic solution from filling
Dispensing device is delivered in cardiac muscle.The cardioplegic solution reverse perfusion pipe of the prior art is by tube body and self-expanding sacculus or pressurized type ball
Capsule composition, middle tube body play the role of conveying cardioplegic solution to intramyocardial, and sacculus plays survey pressure, closing blood flow and fixed inverse
Effect to intrusion pipe.
But actual clinical in use, due to prior art reverse perfusion pipe design balloon position more rearward, intrusion pipe
Head end protrude from that sacculus is longer, frequent occurrence to the damage of perfusion local vessel wall；Shape additionally, due to sacculus is spindle
Shape is easy to and shift, and needs constantly to adjust playback, that is, extends the complexity that operating time increases operation again.
The purpose of the present invention is improving the deficiency of existing cardioplegic solution reverse perfusion pipe, prevent conduit head end in art from damaging
The problem of blood vessel and easily displacement.
Summary of the invention
In order to solve the above problem, sacculus is optimized for by the spindle of script deformable by optimization design of the present invention sacculus
Sphere is in apple shape, spherical in the raised concave end in one end.When conduit is inserted into coronary sinus vein, because balloon distal by
The resistance of part, the depressed section of sacculus are located at operator proximal end, and convex portion is located at extension, to keep conduit insertion flat
It is suitable.When external force releasing or sacculus fluid injection, sacculus convex portion is located at operator proximal end, and depressed section is located at tube body extension
End, depressed section can prevent hard head end from damaging blood vessel prior to plug end in contact blood vessel.
A kind of cardioplegic solution reverse perfusion pipe, the cardioplegic solution reverse perfusion pipe is by tube body (1), sacculus (2) group
At；
The tube body (1) is hollow siphunculus, is divided into three parts: extension (101), middle section (102), pipe shaft portion
Divide (103)；The extension (101) and middle section (102) are furnished with liquid drain hole；
The sacculus (2) is the deformable full hollow ball for being furnished with tiny liquid drain hole, is in one end protrusion one end recess
It is fixed on the outside of tube body middle section (102)；The two fixing points of the sacculus (2) are respectively middle section (102) and stretch out
The partially intersection of (101) intersection and middle section (102) and pipe body part (103).
Further, the expanded state is that sacculus (2) is spherical in the raised concave end in one end in addition to fixed point both ends,
Rest part is in heave shape.
Preferably, the tube body (1) is made of one of polyvinyl chloride, polyurethane, nylon, silica gel, latex material
Or it several is mixed.
Preferably, the sacculus (2) is made of one of polyvinyl chloride, polyurethane, nylon, silica gel, latex material
Or it several is mixed.
Preferably, the pipe shaft (1), sacculus (2) fixed form are to be integrally formed or be bonded.
Preferably, for the sacculus (2) in non-perfusing, recess is located at operator proximal end on one side；In perfusion,
Sacculus (2) recess is located at operator distal end on one side, and sacculus (2) depressed section contacts intravascular prior to tube body extension (101)
Wall.
When in use based on cardioplegic solution reverse perfusion pipe of the present invention, patient's blood is damaged without having to worry about hard head end in art
Pipe, meanwhile, insertion process is more smooth.

Specific embodiment
Following non-limiting embodiments can with a person of ordinary skill in the art will more fully understand the present invention, but not with
Any mode limits the present invention.
Test method described in following embodiments is unless otherwise specified conventional method；The reagent and material, such as
Without specified otherwise, commercially obtain.
Embodiment 1
A kind of cardioplegic solution reverse perfusion pipe, the cardioplegic solution reverse perfusion pipe are made of tube body 1, sacculus 2；
Tube body 1 is hollow siphunculus, is divided into three parts: extension 101, middle section 102, pipe body part 103；It stretches out
Part 101 and middle section 102 are furnished with liquid drain hole；Sacculus 2 is the deformable full hollow ball for being furnished with tiny liquid drain hole, is in one
Raised one end recess is held to be fixed on 1 middle section of tube body, 102 outside；The two fixing points of sacculus (2) are respectively middle section
102 with the intersection of extension 101 intersection and middle section 102 and pipe body part 103.During the fixed point of sacculus 2 is located at
Between part 102 and extension 101 and pipe body part 103 intersection, pipe shaft 1,2 fixed form of sacculus be integrally formed, be
