Problems solved by technology

[0004] The disadvantage of this is that after the filling is completed, the connector is exposed outside the vagina or curled and inserted into the vagina. Since the vagina is a natural environment for bacteria, the balloon and catheter penetrate the entire uterine cavity and vagina and even contact the outside world. Increases the risk of infection so that the balloon is usually not left in the uterus for more than a week, thus compromising the expected anti-adhesion effect of the balloon

Embodiment 1

[0036] Such as figure 1 A balloon uterine stent shown is used to prevent intrauterine adhesions after intrauterine surgery, including a catheter 10 and a balloon 20 connected to the catheter 10 . The catheter 10 includes a first segment catheter 11 and a second segment catheter 12. In this application, the first segment catheter 11 specifically refers to the catheter portion close to the balloon 20, while the second segment catheter 12 specifically refers to the portion far away from the balloon. Catheter part. One end of the first section of catheter 11 is connected to the balloon 20 . The other end of the first section of conduit 11 is connected to the second section of conduit 12 through a check valve 30 . The inlet side of the check valve 30 is arranged at the second section of conduit 12, and the outlet side is arranged at the first section of conduit 11, so that the fluid flow direction can only flow from the second section of conduit 12 through the first section of co...

Embodiment 2

[0040] On the basis of Embodiment 1, a balloon uterine stent is provided, which includes all the components in the embodiment, and optimizes the connection between the check valve 30 and the first section of catheter 11 and the second section of catheter 12 . Although in the first embodiment, it is pointed out that the check valve 30 can be connected with the first section of conduit 11 and the second section of conduit 12 through conventional mechanical processing means in this field. However, considering the processing cost, the connection method in this embodiment is preferred. In this embodiment, the first section of conduit 11 and the second section of conduit 12 are two separate conduits. The first section of catheter 11 is connected to the balloon 20 . The balloon uterine stent also includes a first connection seat 41 and a second connection seat 42 , and the first connection seat 41 and the second connection seat 42 are in a matable connection, such as threaded connec...

Embodiment 3

[0043] On the basis of Embodiment 1 or Embodiment 2, a balloon uterine stent is provided. In this embodiment, the second section of catheter 12 is improved. Even though the length of the catheter that stays outside the body can be shortened by manipulating the second length of catheter 12 after the balloon is inserted, it may be difficult to ensure that the length of the catheter that stays outside just fits the body because the treatment is external. . In this embodiment, the second section of conduit 12 includes a destructible portion 121 , and the destructible portion 121 is also arranged in a tubular structure, and the destructible portion 121 is connected with the check valve 30 . In an embodiment with a connecting seat, the destructible portion 121 is connected to the second connecting seat 42 .

[0044]The dissolution of the instant destruct device 121 is gradual, the water injection process is very short, there will be a dissolution process, and the transportation pro...

Abstract

The invention provides a uterine balloon with a check device in a catheter. The uterine balloon comprises the catheter, a balloon body and a check valve. The catheter is composed of a first catheter section and a second catheter section. One end of the first catheter section is connected with the balloon body. The other end of the first catheter section is connected with the outlet end of the check valve. The second catheter section is connected with the inlet end of the check valve. An inner cavity of the second catheter section, the check valve and an inner cavity of the first catheter section are communicated with the balloon body. The uterine balloon has the advantages that the size is reduced after the balloon body is fulfilled, the infection risk is reduced, the indwelling time is prolonged, and the use comfort level of a patient is improved. Due to a disposable device made of a degradable material, the disposable property is ensured, and the infection risk is reduced.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a uterine balloon with a non-return device arranged in a catheter. Background technique [0002] Scabs on the wound surface after intrauterine surgery are prone to adhesions. The existing technical solution is to insert a water-filled balloon into the uterus, fill it with water to form a barrier, and take it out after the scabs on the wound surface to prevent adhesion. [0003] In the prior art, filling the balloon requires water injection, the balloon needs to be connected to a catheter, and the catheter is connected to a filling joint, which must be exposed outside the vagina to dock the syringe. [0004] The disadvantage of this is that after the filling is completed, the joint is exposed outside the vagina or curled and inserted into the vagina. Since the vagina is a natural environment for bacteria, the balloon and catheter penetrate the entire uterine cavity and vagina and even contact ...
