Description

Technical Field

[0001] This utility model belongs to the technical field of catheterization devices, specifically relating to a pediatric urological catheterization device with anti-dislodgement function. Background Technology

[0002] Pediatric urological catheterization devices refer to devices used in pediatric urology to catheterize pediatric patients. For example, the existing patent with publication number CN220193299U discloses a "pediatric urological catheterization device for easy fixation, comprising a catheterization component and several sets of fixing components; the catheterization component includes a catheter, a drain tube, and a urine collection bag connected in sequence; one set of fixing components fixes the catheter to the outside of the patient's underwear; the remaining fixing components fix the drain tube to the patient's outer pants or bedding." It can be seen that the device described in this application is a common pediatric urological catheterization device that can be used for catheterization of pediatric urological patients.

[0003] In practical use, the existing pediatric urological catheterization device often experiences the problem of the catheter strap separating from the catheter due to the lack of a well-designed anti-dislodgement structure between the catheter and the catheter strap, and the fact that pediatric patients are relatively active. This reduces the stability of use. Therefore, this utility model proposes a pediatric urological catheterization device with an anti-dislodgement function. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1 to 4 This embodiment of the present invention provides a technical solution: a pediatric urological catheterization device with anti-dislodgement function, comprising...

[0024] The catheter bag 1, the socket 2 set at the top of the catheter bag 1, the plug 3 inserted into the top of the socket 2, the catheter tube 4 set on the top surface of the plug 3, and the silicone soft cannula 41 set at the top of the catheter tube 4, wherein the catheter tube 4 and the plug 3 are an integral structure, and the catheter bag 1 and the socket 2 are an integral structure.

[0025] The anti-dislodgement structure 5, located between the socket 2 and the plug 3, includes two side plates 51 movably mounted on both sides of the socket 2, with the top of each side plate 51 extending to one side of the plug 3. An anti-dislodgement block 52 is fixed to the inner side of the top of each side plate 51, and the anti-dislodgement block 52 is engaged with the top surface of the plug 3. This provides a good anti-dislodgement limiting effect between the socket 2 and the plug 3, ensuring the connection stability between the catheter 4 and the catheter bag 1. The anti-dislodgement structure 5 also includes an inner groove 53 formed inside the socket 2 and a device installed in the inner groove 53. The inner spring 54 and inner slide plate 55, and the side connecting rod 56 fixed to the side of the anti-detachment structure 5, the end of the side connecting rod 56 extends through to the surface of the socket 2 and is fixed with a shaft 58. The bottom end of the side plate 51 is rotatably sleeved on the surface of the shaft 58, and a circular end block 57 is fixed on the end surface of the shaft 58 relative to one side of the side plate 51. Under the pushing action of the spring 54, the anti-detachment block 52 can be stably locked at the top edge of the plug 3 during daily use, preventing the socket 2 and the plug 3 from falling off due to external force.

[0026] One end of the spring 54 rests against the side of the inner slide plate 55, and the other end of the spring 54 rests against the inner wall of the inner slide groove 53.

[0027] The socket 2 has a side hole on both sides that communicates with the inner slide groove 53, and the side hole is adapted to the side connecting rod 56 so that the side connecting rod 56 can pass through smoothly.

[0028] The bottom surface of the side plate 51 has a circular hole that matches the shaft 58, so that the bottom of the side plate 51 can be smoothly fitted onto the surface of the shaft 58.

[0029] The anti-detachment structure 5 also includes a C-shaped rubber block 59 glued to the side of the circular end block 57. A positioning component is provided between the C-shaped rubber block 59 and the side plate 51. The positioning component includes a positioning protrusion 591 and a positioning groove 511. The two ends of the C-shaped rubber block 59 extend to the top and bottom of the circular end block 57, respectively. Both ends of the C-shaped rubber block 59 are provided with an integral positioning protrusion 591. Both are made of rubber and will undergo elastic deformation when squeezed. Two positioning grooves 511 corresponding to the positioning protrusions 591 are opened on the side of the side plate 51. The ends of the positioning protrusions 591 are embedded in the positioning grooves 511, which can play an auxiliary positioning role for the side plate 51 after it is rotated.

[0030] The catheter bag 1 has a drain tube at the bottom, and the surface of the silicone soft tube 41 has two integrated silicone protrusions. The silicone soft tube 41 can be inserted into the patient's urethra for catheterization. The urine will enter the catheter bag 1 through the catheter tube 4. After the catheter bag 1 is full of urine, the drain tube at the bottom of the catheter bag 1 can be unscrewed and poured out.

[0031] In summary, when it is necessary to separate the socket 2 and plug 3 later, simply pull the side plate 51 forcefully to the side, causing the side connecting rod 56 to move the inner sliding plate 55 to the side and compress the spring 54, so that the anti-disengagement block 52 is no longer at the top of the plug 3. Then, rotate the side plate 51 around the shaft 58. During the rotation, the end of the positioning protrusion 591 will be squeezed out of the positioning groove 511 at the initial position, so that the side plate 51 can rotate smoothly. When the side plate 51 rotates 180 degrees around the shaft 58, the anti-disengagement block 52 is at the bottom of the socket 2. At this time, the end of the positioning protrusion 591 will be squeezed into another positioning groove 511, so that the side plate 51 is limited after rotation, so that the side plate 51 and the anti-disengagement block 52 no longer block the plug 3 from being pulled out. At this time, the plug 3 can be pulled out from the socket 2 normally to achieve separation.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
