Embodiment 1

[0029] Such as figure 1 As shown, the embodiment of the present invention provides a connection valve, which includes a valve body 1 with a first middle through hole 111 and a first elastic pad 2 that covers the end of the first middle through hole 111. The end surface of the elastic pad 2 is marked with a cutout; a pressing rod 3 with a second middle through hole 31 is provided, and one end of the pressing rod 3 abuts against the cutout of the first elastic pad 2; it is used to adjust the opening or closing state of the cutout of the first elastic pad 2 The gear unit, the gear unit includes an open gear and a closed gear; a press rotation fixing mechanism for fixing the pressing rod 3 on the open gear or the closed gear; when the pressing rod 3 is fixed on the open gear, the first middle through hole 111 communicates with the second middle through hole 31, and when the pressing rod 3 is fixed at the closing gear, the first middle through hole 111 and the second middle through...

Embodiment 2

[0033]In an alternative embodiment of the present invention, see figure 1 , image 3 and Figure 4 , the connection valve can also include a sleeve 4 with two ends open, the middle part of the inner wall of the sleeve 4 protrudes to one end to form a plurality of long opening slots 41 and short opening slots 42 uniformly arranged along the circumferential direction, and the long opening slots 41 and opening short grooves 42 are alternately arranged, and one end protrudes near the sleeve 4 ends to form a closed end, and the closed end of the open long groove 41 forms a closed gear, and the closed end of the open short groove 42 forms an open gear. Wherein, the sleeve 4 can be sleeved on the outside of the valve, and the long opening slots 41 forming the closing gear and the short opening slots 42 forming the opening gear are arranged along the circumferential direction of the inner wall of the sleeve 4, so that the pressing, rotating and fixing mechanism can In the process of...

Embodiment 3

[0035] In an alternative embodiment of the present invention, see figure 1 , Figure 4 and Figure 5 The end of the pressing rod 3 away from the first elastic pad 2 can be fixedly provided with a pressing cover 5 coaxial with the pressing rod 3, and a slider 51 is arranged on the outside of the pressing cover 5, and the slider 51 is placed in the long opening slot 41 and can be Sliding along the open long slot 41, specifically, the pressing rod 3 and the pressing cover 5 can be integrally formed to ensure their strength. By setting the slider 51 on the outside of the pressing cover 5, and the number of the slider 51 can be the same as the number of the opening slot 41, and the width of the slider 51 can be adapted to the width of the opening slot 41, so that the slider The block 51 slides up and down in the open slot 41 as the pressing rod 3 moves up and down, so as to guide the movement of the pressing rod 3, so that the pressing rod 3 can move smoothly under the control of...

Abstract

The invention is applicable to the technical field of a medical appliance, and provides a connecting valve. The connecting valve comprises a valve body provided with a first middle through hole and afirst elastic pad sealing and covering the end part of the first middle through hole, wherein a cut is cut at the end surface of the first elastic pad; the connecting valve also comprises a pressing rod provided with a second middle through hole, a gear unit used for regulating the open or sealed and closed state of the cut of the first elastic pad and a pressing rotary fixing mechanism used for fixing the pressing rod at an open gear or a sealed and closed gear; one end of the pressing rod is abutted against the cut of the first elastic pad; the gear unit comprises the open gear and the sealed and closed gear; when the pressing rod is fixed at the open gear, the first middle through hole communicates with the second middle through hole; and when the pressing rod is fixed at the sealed andclosed gear, the first middle through hole is disconnected from the second middle through hole. The stability and the operation convenience of the connecting valve are improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a connection valve. Background technique [0002] Y-type connection valve is a common medical device in interventional therapy such as cardiac interventional surgery. chance of complications. [0003] At present, there are usually two types of existing Y-type connection valves. One is the screw-type Y-valve, which generally controls the tightness of the inner silicone ring and the catheter by turning the knob to realize its closed or open working state. One kind of Y valve can fix the catheter better, but it is prone to leakage during the process of fixing the blood lock, and the doctor needs to rely on experience to manually adjust the operation during operation. The other is the push-type Y-valve, which is generally operated by pressing the cap Control the diameter of its internal channel to realize its closed or open working state. This kind of Y valve can better...
