[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 6 As shown, this utility model provides a balloon catheter that does not affect blood flow, including a tube body 8. The tube body 8 is made entirely of polyurethane material, which has excellent elasticity and flexibility, allowing the balloon catheter to bend and move flexibly within the blood vessel, adapting to the complex course and physiological curvature of the blood vessel, effectively reducing mechanical stimulation and damage to the blood vessel wall. At the same time, the cap material has good biocompatibility and wear resistance, which means that it has little interaction with human tissue and blood, effectively reducing the corresponding risks. This material enables the new balloon catheter to effectively reduce the adsorption of cells and proteins when in contact with blood and vascular tissue, reducing the possibility of thrombosis and helping to maintain the stability of the intravascular environment.

[0026] The tube body 8 has a first slot 10, and the balloon 13 is secured in the first slot 10. The balloon 13 is made entirely of polyether block amide material, which not only has excellent biocompatibility and flexibility, but also excellent elastic recovery performance. This allows the balloon 13 to expand and contract more smoothly and flexibly, adapting to blood vessels of different shapes and sizes, and is suitable for work situations where users need to frequently expand and contract blood vessels.

[0027] Multiple air inlets 15 are provided around the 8th circumference of the tube body. Multiple air inlets 14 are provided on both ends of the balloon 13. One end of each air inlet 14 is inserted into one of the multiple air inlets 15. The cooperation of the multiple air inlets 15 and air inlets 14 can promote the rapid and balanced distribution of gas in the balloon 13, making the balloon 13 expand more evenly. This structure reduces fatigue damage caused by uneven force or excessive stretching during the inflation and deflation of the balloon 13, thereby effectively improving the reliability and stability of the entire device in complex surgical environments and extending the service life of the balloon 13.

[0028] The first clamping groove 10 is provided with a second clamping groove 11, and the second clamping groove 11 is clamped with a developing ring 12. The developing ring 12 is clearly visible in X-ray or other imaging examination, which can help the user to understand the position and movement of the balloon 13 in real time during use, so as to adjust the operation strategy in time, effectively avoid the treatment failure caused by position deviation, so that the user can quickly complete the operation, reduce the time wasted by repeatedly confirming the position, and effectively improve the use efficiency.

[0029] The connecting block 5 is sleeved on the pipe body 8, one end of the connecting block 5 is provided with an injection port 6, the injection port 6 provides a special and fixed injection position for the user, which facilitates the user to inject drugs or contrast medium, and ensures that the injection position is relatively fixed each time, effectively avoiding the inaccuracy of injection position and dose error caused by random searching of injection point on the pipe body 8, thereby improving the accuracy and efficiency of operation.

[0030] The first exchange hole 16 is arranged in the connecting block 5, the second exchange hole 7 is arranged at one end of the connecting block 5, one end of the second exchange hole 7 is connected with the first exchange hole 16, the gas valve 2 is clamped at one end of the connecting block 5, and one end of the pipe body 8 is clamped in the gas valve 2 through the first exchange hole 16. This design effectively increases the diversity of the exchange path, ensures that the pipe body 8 can be used alternately according to the first exchange hole 16 and the second exchange hole 7 during use, and effectively improves the use efficiency and use effect of the device. This clamping structure effectively improves the tightness and stability of the connection, prevents gas leakage, ensures that the gas can be accurately and reliably delivered into the pipe body 8 and into the balloon 13, thereby improving the safety and effectiveness of the treatment.

[0031] The pressure gauge 3 and the pressure regulator 4 are clamped on one side of the gas valve 2, the pressure pump 1 is clamped at one end of the gas valve 2, the pressure gauge 3 can display the pressure value in the gas valve 2 in real time, so that the user can clearly understand the pressure condition and find pressure abnormalities in time, and the pressure regulator 4 can accurately adjust the pressure according to actual needs, so as to ensure that the inflation or contraction degree of the balloon 13 meets the precise requirements of treatment. The pressure pump 1 can quickly provide a stable pressure source for the balloon catheter, shorten the operation preparation time, and effectively improve the treatment efficiency. The direct connection of the pressure pump 1 and the gas valve 2 effectively reduces the loss and fluctuation in the pressure transmission process, and ensures the stable supply of pressure.

[0032] One end of the pipe body 8 is clamped with the induction head 17, the pipe body 8 is provided with the dredging groove 18, one end of the dredging groove 18 is connected with the open slot 9, the induction head 17 can sense the environmental information of the front end of the pipe body 8 in real time, so that the user can better control the operation process and adjust the treatment scheme, the setting of the dredging groove 18 and the open slot 9 ensures that the balloon catheter is not hindered in the blood vessel to ensure that the pressure distribution in the blood vessel is more uniform, effectively ensuring the health and stability of the blood vessel.

[0033] The specific use mode and effect of the embodiment are as follows:

[0034] When the user uses the novel balloon catheter, the pipe body 8 can be inserted into the target blood vessel first, and then the induction head 17 at one end of the pipe body 8 and the developing ring 12 are used to determine the position to be treated. The user can understand the contact condition of the front end of the pipe body 8 and the blood vessel wall in time by the feedback of the induction head 17, so as to effectively avoid unnecessary damage to the blood vessel caused by improper insertion force or angle deviation. This accurate positioning mode provides clear operation guidance for the user, effectively reduces the difficulty and uncertainty of operation, so that the user can maintain confidence and composure during operation, which helps to improve the success rate and quality of operation.

[0035] Then the user can accurately adjust the pressure required by the pressure gauge 3 and the pressure regulator 4 on the air valve 2, so that the balloon 13 can be uniformly inflated. Accurate pressure control can effectively avoid the situation that the pressure cannot reach the expected treatment effect. The blood vessel conditions and diseases of different patients may be different, and accurate pressure adjustment can customize the treatment scheme according to individual needs, improve the pertinence and effectiveness of treatment.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments.
