Description

Technical Field

[0001] This utility model belongs to the field of catheter balloons, specifically a TPU catheter balloon. Background Technology

[0002] A endotracheal tube balloon is a medical device used for endotracheal intubation. It usually consists of an endotracheal tube and a balloon. Its main function is to ensure that the airway is open by inserting it into the body through the endotracheal tube. The balloon part can be inflated in the endotracheal tube to form a seal to prevent leakage of respiratory secretions or gas, and also helps to fix the position of the tube.

[0003] A catheter is a long, flexible tubular structure that guides a balloon to the desired treatment site within the body. The balloon is the distal end of the catheter and is usually made of expandable material. When used, the balloon inflates to apply pressure for treatment. Most existing balloons are made of polyurethane or silicone. Polyurethane balloons have lower chemical stability, while silicone balloons are less elastic and more brittle. Both have their own drawbacks, making it impossible to ensure the durability of the balloon.

[0004] In summary, this invention provides a TPU catheter balloon to solve the above problems. Utility Model Content

[0021] Example 1

[0022] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a TPU catheter balloon, including a balloon front end 1, a balloon rear cover 2 detachably connected to the back of the balloon front end 1, both the balloon front end 1 and the balloon rear cover 2 are made of TPU material, an installation tube 3 is fixedly connected to the front of the balloon front end 1, and a catheter body 4 is detachably connected to the inner cavity of the installation tube 3. An installation mechanism 5 is provided on the surface of the balloon front end 1, the installation mechanism 5 includes two fixing rings 501, the two fixing rings 501 are respectively located on the surface of the balloon front end 1 and the balloon rear cover 2, and are fixedly connected to their surfaces, a receiving groove 502 is opened on the back of the front fixing ring 501, and a first sealing sleeve 503 is fixedly connected to the front of the rear fixing ring 501, the front end of the first sealing sleeve 503 extends into the inner cavity of the receiving groove 502, and is detachably connected to the inner cavity of the receiving groove 502.

[0023] like Figure 1-4 As shown, the airbag front end 1 and airbag rear cover 2 constitute the airbag body. Both the airbag front end 1 and airbag rear cover 2 are made of TPU material. TPU is a high-performance plastic material with excellent elasticity, wear resistance and chemical resistance. It combines the elasticity of rubber and the processing performance of plastic, and has good flexibility and durability. It can combine the advantages of polyurethane and silicone and make up for the disadvantages of both, improving the durability of the balloon. At the same time, the TPU balloon is thinner and lighter, making it easier to use. The installation tube 3 is used to install the catheter body 4. The installation mechanism 5 can splice the airbag front end 1 and airbag rear cover 2 together. At the same time, the installation mechanism 5 can also be used to disassemble the airbag front end 1 and airbag rear cover 2 for comprehensive internal disinfection, so that it can be reused multiple times, thereby reducing costs and improving practicality.

[0024] Example 2

[0025] Reference Figure 2 and 4This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] In this embodiment, fixing blocks 504 are fixedly connected to both sides of the fixing ring 501, and mounting grooves 505 are opened on the front of the two fixing blocks 504 at the rear end.

[0027] The back of each of the two front fixing blocks 504 is fixedly connected to a mounting block 506. The rear end of the mounting block 506 extends into the inner cavity of the mounting groove 505 and engages with the inner cavity of the mounting groove 505.

[0028] An anti-slip sleeve 507 is fitted onto the surface of the mounting block 506, and the surface of the anti-slip sleeve 507 is in close contact with the inner wall of the mounting groove 505.

[0029] like Figure 2 and 4 As shown, the fixing ring 501 is used to support and fix the components on its surface, improving the stability of each component during use. The receiving groove 502 is used to receive the first sealing sleeve 503. After the first sealing sleeve 503 is inserted into the receiving groove 502, it can seal the gap between the airbag front end 1 and the airbag rear cover 2, preventing air leakage in the gap. After the mounting block 506 is inserted into the mounting groove 505, the anti-slip sleeve 507 will be in close contact with the inner wall of the mounting groove 505. The anti-slip sleeve 507 can increase the friction between the mounting groove 505 and the mounting block 506, playing an anti-slip role, thereby improving the stability of the connection between the airbag front end 1 and the airbag rear cover 2.

[0030] Example 3

[0031] Reference Figure 1 and 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] In this embodiment, the inner cavity of the installation tube 3 is fixedly connected with a second sealing sleeve 6, and the rear end of the surface of the conduit body 4 is in close contact with the inner wall of the second sealing sleeve 6.

[0033] The top and bottom of the rear retaining ring 501 are fixedly connected to the push frame 7, and both sides of the push frame 7 are fixedly connected to the surfaces of the two rear retaining blocks 504.

[0034] like Figure 1 and 3 As shown, the second sealing sleeve 6 can seal the positioning gap between the installation tube 3 and the catheter body 4 to prevent air leakage between the installation tube 3 and the catheter body 4. The pusher 7 plays a major role in facilitating the rear cover 2 of the airbag to be pushed backward, so that the rear cover 2 of the airbag can be removed from the back of the front end 1 of the airbag for thorough disinfection.

[0035] During use, since both the airbag front end 1 and the airbag rear cover 2 are made of TPU, a high-performance plastic material with excellent elasticity, wear resistance, and chemical resistance, it combines the elasticity of rubber with the processing properties of plastic, possessing good flexibility and durability. It combines the advantages of polyurethane and silicone while mitigating their disadvantages, improving the durability of the airbag. Simultaneously, the TPU airbag is thinner and lighter, making it more convenient to use. When installing the airbag front end 1 and airbag rear cover 2, first move the airbag rear cover 2 to the back of the airbag front end 1, then push the airbag rear cover 2 forward, causing the first sealing sleeve 503 to gradually... The mounting block 506 is gradually inserted into the inner cavity of the mounting groove 505. After the first sealing sleeve 503 is inserted into the inner cavity of the mounting groove 502, it can seal the gap between the front end 1 of the airbag and the rear cover 2 of the airbag, preventing air leakage. After the mounting block 506 is inserted into the inner cavity of the mounting groove 505, the anti-slip sleeve 507 will be in close contact with the inner wall of the mounting groove 505. The anti-slip sleeve 507 can increase the friction between the mounting groove 505 and the mounting block 506, playing an anti-slip role, thereby improving the stability of the connection between the front end 1 of the airbag and the rear cover 2 of the airbag.
