Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multi-balloon catheter balloon inflation volume display device. Background Technology

[0002] A multi-balloon catheter balloon is a device or consumable used in medical treatment. It is widely used in interventional treatments, especially in some treatments that require dilation or repair, such as endotracheal intubation and urinary catheterization, where a balloon is often used.

[0003] When multi-cystic catheter balloons are produced and put into use, they need to be inflated beforehand to ensure their sealing effect. However, the current measurement methods are quite cumbersome and mostly use individual testing, which cannot guarantee the overall testing efficiency of multi-cystic catheter balloons.

[0022] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figure 1-3 The multi-cyst catheter balloon inflation volume display device includes a mounting plate 1, suction cups 2 are installed at the four corners of the lower wall of the mounting plate 1, and four operating boxes 3 are provided at the upper end of the mounting plate 1. An inflation volume display structure is installed in each of the four operating boxes 3.

[0024] The air volume display structure includes: mounting slot 4, fixing bracket 5, pressure display component, air inlet pipe 6, one-way valve 7, air delivery pipe 8, and pressure relief delivery component;

[0025] The mounting slot 4 is located on the outer front end of the operating box 3. The fixing bracket 5 is fixedly installed on the rear wall of the mounting slot 4. The pressure display component is movably embedded in the fixing bracket 5. One end of the air inlet pipe 6 is connected to the bottom end of the pressure display component. The one-way valve 7 is installed on the other end of the air inlet pipe 6. One end of the air delivery pipe 8 is connected to the air inlet pipe 6 through a three-way connector. The pressure relief and delivery component is connected to the other end of the air delivery pipe 8.

[0026] When testing the inflation of a multi-cystic catheter balloon, the operator first uses suction cup 2 to fix the mounting plate 1 to the top of the table. Then, the pressure display component is embedded into the mounting bracket 5 on one side of the mounting slot 4, secured, and connected to the inlet pipe 6. The inlet pipe 6 is then connected to the gas source connection pipe 18, and the inflation volume is controlled by the gas source. Next, the multi-cystic catheter balloon to be tested is connected to the pressure relief delivery component. Through the gas source connection pipe 18 and the inlet pipe 6, gas is delivered to the pressure display component and the delivery pipe 8. A one-way valve 7 prevents gas overflow. The delivery pipe 8, in conjunction with the pressure relief delivery component, allows gas to enter the balloon under test and the pressure display. Inside the component, under the action of the three-way valve 15 and the one-way valve 7, the airbag under test and the pressure display component are in a connected state. Therefore, the gas supplied through the gas source connection pipe 18 will cause the airbag under test to expand and the reading of the pressure display component to change. Once the airbag under test does not meet the sealing requirements, the internal air pressure will inevitably decrease, and the reading at the top of the pressure display component will inevitably change. By comparing the scale value at the top of the pressure display component before the measurement is completed with the scale value at the end of the measurement, it can be determined whether the airbag under test is leaking. During the test, the gas supplied by the gas source can be precisely controlled by the operation of the pressure relief delivery component to avoid damage to the multi-bladder catheter airbag and the pressure display component due to excessive air pressure.

[0027] In the specific implementation process, the pressure display component includes: test tube 9, fixed frame 10, spring tube 11 and sealing plate 12;

[0028] The test tube 9 is movably embedded in the fixed frame 5, and its bottom end is connected to the air inlet pipe 6. The fixed frame 10 is fixedly installed in the upper end of the test tube 9. The top end of the spring tube 11 is connected to the lower end of the fixed frame 10. The sealing plate 12 is movably embedded in the lower end of the test tube 9 and is connected to the lower end of the spring tube 11.

[0029] During the testing process, gas is delivered to the lower end of the test tube 9 through the air inlet pipe 6. As the air pressure increases, the sealing plate 12 is pushed upward at the lower end of the test tube 9. When the thrust of the air pressure is greater than the thrust of the spring tube 11 at the lower end of the fixed frame 10, the sealing plate 12 moves until the thrust on both sides is balanced. By observing the height of the sealing plate 12 in the test tube 9, the inflation test of the multi-cyst catheter balloon can be achieved. When the multi-cyst catheter balloon leaks air, the internal air pressure decreases. Therefore, under the thrust of the spring tube 11, the sealing plate 12 moves downward, which allows for a direct understanding of the leakage situation of the multi-cyst catheter balloon.

[0030] In the specific implementation process, the pressure relief and conveying assembly includes: vent pipe 13, vent valve 14, three-way valve 15, conveying pipe 16, and conveying valve 17;

[0031] One end of the vent pipe 13 is connected to the air supply pipe 8 via a three-way connector, and the other end passes through the rear wall of the operating box 3. The vent valve 14 is installed on the upper end of the vent pipe 13. One end of the three-way valve 15 is connected to the top of the air supply pipe 8. One end of the delivery pipe 16 is connected to one end of the three-way valve 15. The delivery valve 17 is installed on the upper end of the delivery pipe 16.

[0032] During the testing process, gas is introduced into the multi-cyst catheter bladder through the three-way valve 15 and the delivery pipe 16 via the air supply pipe 8 and the three-way connector. When the reading inside the pressure display component is too high, the excess gas inside the multi-cyst catheter bladder and pressure display component is discharged through the vent valve 14 at one end of the vent pipe 13, ensuring the stability of the multi-cyst catheter bladder and pressure display component and preventing damage. After the test is completed, the three-way valve 15 is opened to connect the air supply pipe 8 to the outside, allowing the gas inside the multi-cyst catheter bladder and pressure display component to be discharged and the multi-cyst catheter bladder to be replaced. When the number of multi-cyst catheter bladders tested is three, one of the delivery pipes 16 can be closed through the delivery valve 17 to prevent air leakage.

[0033] In the specific implementation process, an air source connection pipe 18 is embedded on one side of each of the four operating boxes 3.

[0034] In the specific implementation process, the gas source connection pipe 18 is connected to the other end of the one-way valve 7.

[0035] By connecting the gas source connecting pipe 18 to the one-way valve 7 at one end of the multiple air inlet pipes 6, the gas delivered by the gas source delivery equipment can be fully delivered to the multiple air inlet pipes 6. The one-way valve 7 can limit the flow direction of the gas, preventing the gas in the air inlet pipes 6 from entering the gas source connecting pipe 18, thus ensuring the detection effect of the multi-bladder catheter balloon.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
