The main bag 1 and the annular auxiliary bag 2 are both of a flat structure, and both sides of the main bag 1 and the annular auxiliary bag 2 in the axial direction can be made of a non-deformable material, preferably, plastic or the like, and the sides of the main bag 1 and the annular auxiliary bag 2 can be made of an elastic material, preferably, rubber, so that the main bag 1 and the annular auxiliary bag 2 can be deformed only in the axial direction while both axial sides remain flat when internal pressure is applied. Of course, it is also possible to make the primary bladder 1 and the annular secondary bladder 2 entirely of rubber material, which is less effective, but still allows expansion.
The flow-limiting connecting pipe 3 comprises a mounting pipe 3a, two deformation pieces 3c and two connecting pieces 3b, wherein the two deformation pieces 3c and the two connecting pieces 3b are arranged in the mounting pipe 3a and extend along the axis of the mounting pipe 3a, the two deformation pieces 3c are symmetrical relative to a first symmetrical plane, the two connecting pieces 3b are symmetrical relative to a second symmetrical plane, and the first symmetrical plane and the second symmetrical plane are perpendicular to each other and are intersected on the axis of the mounting pipe 3 a.
The deformation piece 3c is a hollow structure, and includes an arc-shaped portion 3c1 attached to the inner side wall of the mounting tube 3a, a pressed portion 3c2 parallel to the first symmetric plane, two side portions 3c3 connecting both sides of the pressed portion 3c2 to both sides of the arc-shaped portion 3c1, respectively, and two connecting portions 3c4 connecting both end portions of the pressed portion 3c2, the arc-shaped portion 3c1, and the side portion 3c3 in the axial direction of the mounting tube 3a, respectively, and the pressed portion 3c2, the arc-shaped portion 3c1, the side portion 3c3, and the connecting portion 3c4 constitute a hollow deformation piece 3 c. The deformable element 3c is made of a deformable material, preferably a rubber material.
The pressed parts 3c2 of the two deforming pieces 3c abut against each other at the position of a first symmetrical plane, the side parts 3c3 of each deforming piece 3c gradually approach to a second symmetrical plane in the process of extending towards the first symmetrical plane, and the connecting piece 3b is arranged in a space enclosed by the side parts of the two deforming pieces 3c and the side wall of the mounting tube 3a, and the shape of the space is the same as that of the connecting piece 3b when viewed along the axis of the mounting tube 3a, so that when the hydraulic pressure is small, the deforming pieces 3c and the connecting piece 3b block the mounting tube 3a, and the physiological saline cannot pass through.
Further, in order to ensure that the deformation piece 3c can bear certain hydraulic pressure, each of the deformation pieces 3c is internally provided with a contact piece 3d, the contact piece 3d is contacted with the pressed part 3c2, an elastic piece 3e is arranged between the contact piece 3d and the arc part 3c1, one end of the elastic piece 3e along the elastic direction is contacted with the contact piece 3d, the other end is contacted with the arc part 3c1, and the elastic piece 3e is always in a compressed state, so that the deformation piece 3c can automatically restore when the hydraulic pressure is smaller. Of course, in actual use, the abutting piece 3d and the elastic piece 3e may not be required, and the deforming piece 3c itself may be made of an elastic material such as rubber.
The arc-shaped part 3c1 of the deforming member 3c and the connecting member 3b are glued to the inner side wall of the mounting tube 3a, although they may be fixed in other ways known in the art.
The two connecting portions 3c4 of each deformable member 3c gradually approach each other in the process of approaching the first plane of symmetry, and the two end faces of each connecting member 3b along the axial direction of the mounting tube 3a gradually approach each other in the process of approaching the second plane of symmetry, so that the connecting portions 3c4 and the end faces of the connecting members 3b form grooves which help the saline solution push the pressed portions 3c2 of the deformable members 3c away from each other. When pushed away, the saline can flow through the gap between the two pressed portions 3c 2.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
