Example Embodiment

[0031] Example 1

[0032] like figure 1 A membrane type balloon catheter shown, the tube body is composed of an outer layer 1 and an inner layer 2, the front part of the tube body is provided with a balloon 4 and a catheter hole 3 communicating with the lumen, and the rear part of the tube body is provided with An inflatable port 5 communicating with the airbag 4 is provided, the end is a urination port 6, and an arched elastic diaphragm 9 is connected to the pipe body on one side of the catheter hole 3 towards the end of the pipe body; the lumen is provided with a Valve mechanism, the valve mechanism includes a valve body 7 and a valve core 10, the edge of the valve body 7 is sealingly connected to the inner wall of the tube cavity, the valve body 7 is provided with a valve core cavity 12, and is respectively connected to the valve core cavity 12 In this embodiment, the outlet is a hole coaxial with the inlet 8, the valve core 10 is arranged in the valve core cavity 12, in o...

Example Embodiment

[0034] Example 2

[0035] like image 3 and Figure 4 In the shown diaphragm-type bladder catheter, the outlet is a through groove with a width smaller than that of the valve core cavity 12, which reduces the friction between the valve core 10 and the valve core cavity 12, and is beneficial to prevent clogging.

[0036] The rest are implemented as in Example 1.

Example Embodiment

[0037] Example 3

[0038] like Figure 5 A membrane type balloon catheter is shown, there are two elastic membranes 9 and two valve cores 10 each, the valve body 7 is provided with two inlets 8, and the two elastic membranes 9 are symmetrical They are arranged on both sides of the pipe body, and each is connected to a valve core 10 , and the movement of each valve core 10 opens or closes an inlet 8 .

[0039] The rest are implemented as in Example 1.

Abstract

The invention discloses a diaphragm-type airbag urinary catheter. The front part of the tube body is provided with an airbag and a catheterization hole communicating with the lumen, the rear part of the tube body is provided with an inflation port communicating with the airbag, and the end is a urination port. An arched elastic diaphragm is connected to the catheter body on one side of the catheter hole at the end of the pipe body, a valve mechanism is arranged in the lumen, and the inner wall of the elastic diaphragm is connected to the valve core of the valve mechanism to drive its action, so that the valve mechanism on or off. When the intravesical pressure is greater than the bearing range of the arched elastic diaphragm, the elastic diaphragm dents in the direction of the tube body and drives the valve core to conduct the valve mechanism to discharge urine. No electronic devices are used at all, and the reliability is high, the cost is low, and the Simple structure and convenient operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a diaphragm-type balloon urinary catheter. Background technique [0002] The balloon catheter is a common clinical device for draining urine. The front part of the tube body is provided with a catheter hole that communicates with the lumen, and a balloon used to prevent the front end of the catheter from being separated from the bladder. The inflatable port of the airbag has a urination port at the end, and when the front part of the tube body is inserted into the bladder at a suitable position, the airbag is inflated through the inflation port to expand and fix it. [0003] On the traditional balloon catheter, the catheter hole and the urination port are always in a connected state, and a little urine in the bladder will be discharged, which leads to the long-term emptying of the bladder. The change of bladder pressure is conducive to maintaining its function, and the change of i...
