[0027] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0028] Example:
[0029] As attached Figure 1 To Attachment Figure 7 As shown:
[0030] The utility model provides an anti-allergic, super-slip and antibacterial medical urinary catheter, comprising a base catheter 11, one end of which is provided with a catheter head 12 for inserting into the urethra and locking the position of the urinary catheter, and the other end of the base catheter 11 is connected with a multi-tube connecting component to achieve the connection of pipelines with different functions; a urinary catheter cavity 13 and a flushing cavity 14 are arranged in the base catheter 11, the urinary catheter cavity 13 is used for urinary catheterization, and the flushing cavity 14 is used for flushing. The two cavities are connected through a flushing port 15 arranged in the base catheter 11, so that the urinary catheter cavity 13 can be easily flushed through the flushing cavity 14, so as to clean the inside of the urinary catheter; at the same time, an overflow check valve 16 is also arranged on the flushing port 15 to prevent the flushing liquid from flowing back from the flushing cavity 14 into the urinary catheter cavity 13 and affecting the urinary catheterization effect; a urinary catheter port 17 is opened on one side of the base catheter 11, so that the urinary catheter port 17 is connected with the urinary catheter cavity 13. At the same time, in order to improve the safety of the urinary catheter, a plurality of functional coatings are arranged on the base catheter 11. Specifically, the base The outer surface of the catheter 11 is provided with a super-slip coating 18, which can reduce the friction when the catheter is inserted into the urethra and reduce the patient's discomfort. At the same time, the outer surface of the base catheter 11 and the inner wall of the catheter cavity 13 are provided with an antibacterial coating 19. By providing the antibacterial coating 19 on both the inner and outer surfaces, bacteria can be prevented and treated from both the inside and the outside, effectively reducing the risk of related cystitis caused by indwelling catheters and improving the safety of the catheters. In addition, the base catheter 11 is also provided with an airbag component, which can fix the catheter in the urethra by inflation, thereby locking the catheter.
[0031] Please refer to Figure 2 and Figure 3 As shown, the super-slip coating 18 is formed by a modified chitosan super-slip coating material grafted on the outer surface of the base catheter 11 using photocatalytic grafting technology and mussel bionic technology. The surface friction of the super-slip coating 18 is 0.2N. After using this new super-slip coating 18, the catheter can be inserted into the urethra more easily. Compared with the traditional catheter that needs to be manually lubricated before each use, the super-slip coating 18 does not require additional lubricant, which can greatly reduce the friction during the insertion of the catheter, which allows patients to experience less discomfort when using the catheter. At the same time, compared with the traditional catheter that needs to be manually lubricated, the super-slip coating 18 is also more convenient and quicker. It solves the inconvenience of additional operations required before each use of the traditional catheter, and effectively improves the convenience of use of the catheter. The antibacterial coating is made of quaternary ammonium salt material.
[0032] Please refer to Figure 2 , Figure 5 and Figure 6As shown, the multi-tube connection assembly includes a multi-way connector 21. The multi-way connector 21 is installed on one side of the base catheter 11. Moreover, the multi-way connector 21 corresponds to the flushing cavity 14. A flushing tube 22 is specially provided so that the various components can be effectively connected and cooperated to ensure the normal operation of the urinary catheter. The existence of the flushing tube 22 provides a special channel for the flushing cavity 14, making the flushing process smoother and more efficient.
[0033] Please refer to Figure 5 and Figure 6 As shown, one end of the flushing tube 22 is connected to the flushing cavity 14, and the other end is provided with a one-way flushing valve 23. This design allows the flushing liquid to flow in a specific direction, improving the flushing effect and efficiency. The one-way flushing valve 23 can control the flow of the flushing liquid, prevent backflow and leakage, and ensure smooth flushing.
[0034] Please refer to Figure 6 As shown, the multi-tube connection assembly also includes a urinary catheter connection tube 24, and the end of the urinary catheter cavity 13 away from the catheter head 12 is connected to the urinary catheter connection tube 24, and a connector 25 is provided at one end of the urinary catheter connection tube 24. The urinary catheter connection tube 24 and the urinary catheter cavity 13 are closely connected to form an unobstructed urinary catheterization channel; and the connector 25 on the urinary catheter connection tube 24 provides convenience for connection with other components.
[0035] Please refer to Figure 6 and Figure 7 As shown, the multi-way connector 21 is also equipped with an inflation tube 26, one end of the inflation tube 26 is connected to the airbag assembly, and the other end is provided with an inflation connector 27. In order to ensure the sealing and stability of inflation, a sealing sleeve 28 is provided on the inflation connector 27; specifically, the multi-way connector 21 enables the inflation tube 26 to be smoothly connected to the airbag assembly, and the design of the inflation connector 27 provides a convenient inflation operation interface, and the presence of the sealing sleeve 28 further enhances the sealing performance of the inflation connector 27 to prevent gas leakage.
[0036] Please refer to Figure 6 As shown, the airbag assembly includes an airbag 31. The airbag 31 is arranged on the outer surface of the base catheter 11. An inflation cavity 32 is opened on the base catheter 11, and an inflation port 33 is opened at one end of the inflation cavity 32 to be connected with the airbag 31. During the process of inflating the airbag assembly through the inflation tube 26, the airbag 31 can be fully expanded in the body. This unique design enables the urinary catheter to be firmly locked in a suitable position. The expansion of the airbag 31 not only increases the stability, but also reduces the movement of the urinary catheter in the body, reduces the possible discomfort and irritation, and brings a more comfortable experience to the patient.
