Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a urinary catheter with a fixed structure. Background Art

[0002] A urinary catheter is a tube used to drain urine. It is inserted from the urethra into the bladder to drain urine. After the catheter is inserted into the bladder, there is a balloon near the catheter head to fix the catheter in the bladder and prevent it from coming out. The drainage tube is connected to a urine bag to collect urine. There is also a water injection tube on the catheter, from which 10-15 ml of water is injected to fill the balloon and get stuck in the bladder to prevent the tube from coming out.

[0003] At present, the interface of the urinary catheter is a plug-in type, which is easy to fall off due to loose fixation, thereby causing urine leakage. At the same time, if the urinary catheter is not fixed, the patient's activities and turning over are easy to involve the urinary catheter, which not only causes the urinary catheter to fall off, but also causes discomfort and pain to the patient. Therefore, the utility model proposes a urinary catheter with a fixed structure. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The utility model provides Figure 1-6 The catheter with a fixed structure shown in the figure comprises a catheter body, wherein the catheter body comprises a catheter body 1 and a water injection pipe 2, and one end of the catheter body 1 is connected to a drainage pipe 3 of a urine bag.

[0032] In order to improve the connection stability between the urinary catheter body 1 and the drainage tube 3, as Figure 2-3As shown, a threaded interface 4 is fixedly provided at one end of the catheter body 1, and an inner threaded cavity 5 is provided on the inner wall of one end of the drainage tube 3 close to the catheter body 1, and the threaded interface 4 is threadedly connected to the inner threaded cavity 5, and a sealing ring can be sleeved between the catheter body 1 and the drainage tube 3 to ensure the sealing between the two; the threaded connection between the catheter body 1 and the drainage tube 3 is realized by screwing the threaded interface 4 into the inner threaded cavity 5, replacing the current plug-in connection, improving the connection stability between the catheter body 1 and the drainage tube 3, and avoiding falling off due to loose fixation and causing urine leakage.

[0033] Furthermore, the catheter body 1 and the drainage tube 3 are reinforced by a reinforcement component 6; specifically, Figure 4-5 As shown, the reinforcement component 6 includes a sleeve 61 fixed to the outer wall of one end of the catheter body 1, and an opening 67 is opened on the sleeve 61. The sleeve 61 is sleeved on the outside of the drainage tube 3, and a cavity 62 is opened on the outside of the drainage tube 3 near the end of the catheter body 1, and the cavity 62 is communicated with the opening 67. A limiting block 63 is provided in the cavity 62, and the limiting block 63 passes through the opening 67 and extends out of the sleeve 61 to clamp the drainage tube 3 and the sleeve 61, and the top of the limiting block 63 is processed into an inclined surface, and the limiting block 63 is An inner rod 65 and an outer tube 66 are provided between the block 63 and the inner wall of the cavity 62. One end of the inner rod 65 away from the limiting block 63 extends into the outer tube 66, and the inner rod 65 can slide and rotate inside the outer tube 66 to facilitate the rotation of the limiting block 63. A spring 64 is provided in the cavity 62, and the spring 64 is provided on the outside of the inner rod 65 and the outer tube 66. One end of the spring 64 is fixedly connected to the inner wall of the cavity 62, and the other end of the spring 64 contacts the limiting block 63, that is, the spring 64 and the limiting block 63 are not fixed.

[0034] When the threaded interface 4 is screwed into the internal threaded cavity 5, the sleeve 61 is driven to gradually approach the limit block 63. The sleeve 61 first contacts the inclined surface of the limit block 63. The sleeve 61 continues to move and presses the limit block 63. The limit block 63 squeezes the inner rod 65 and the spring 64. The inner rod 65 slides downward along the outer tube 66. When the threaded interface 4 is screwed into place, the opening 67 is communicated with the cavity 62, so that the limit block 63 is stuck in the opening 67 under the elastic force of the spring 64. Since the limit block 63 limits the rotation of the sleeve 61, it can effectively prevent the threaded connection between the threaded interface 4 and the internal threaded cavity 5 from loosening, thereby improving the stability of the connection between the urinary catheter body 1 and the drainage tube 3, and further preventing the urinary catheter body 1 and the drainage tube 3 from falling off due to loose fixation.

[0035] When the urinary catheter body 1 and the drainage tube 3 are disassembled, the limiting block 63 is rotated 90°. Figure 6As shown, the direction of the inclined surface of the limit block 63 is opposite to the direction in which the threaded interface 4 of the catheter body 1 rotates. When the catheter body 1 is rotated, the sleeve 61 is driven to contact the inclined surface of the limit block 63 to press down the limit block 63. At this time, the limit block 63 will not prevent the sleeve 61 from rotating, and then the threaded interface 4 can be screwed out of the internal thread cavity 5.

[0036] like Figure 1-2 As shown, a clamping assembly 7 for fixing the water injection pipe 2 is provided on the outer wall of one end of the drainage tube 3 close to the catheter body 1, and the clamping assembly 7 includes a sleeve ring 71 fixedly sleeved on the outer wall of one end of the catheter body 1, and an arc-shaped fixed splint 72 and an arc-shaped movable splint 73 are provided on the outer side of the sleeve ring 71, the arc-shaped fixed splint 72 is fixed to the sleeve ring 71, and the arc-shaped movable splint 73 is rotatably connected to the arc-shaped fixed splint 72, and the water injection pipe 2 is clamped in the arc-shaped fixed splint 72 and the arc-shaped movable splint 73, and two connecting blocks 2 75 are fixedly provided on the side of the arc-shaped movable splint 73 close to the sleeve ring 71, and two connecting blocks 1 74 are fixedly provided on the side of the arc-shaped fixed splint 72 close to the sleeve ring 71, and the connecting block 2 75 is rotatably connected to the connecting block 1 74 through a rotating shaft, and a shifting block 77 is fixed on the arc-shaped movable splint 73 for facilitating the rotation of the arc-shaped movable splint 73, and a torsion spring 76 is sleeved on the rotating shaft.

[0037] Moreover, if Figure 2 As shown, a fixing block 8 is fixed to the outside of the ring 71 on one side away from the arc-shaped fixing splint 72, and an adhesive 9 for fixing to the patient's body is provided on the fixing block 8.

[0038] After the catheter body 1 is connected to the drainage tube 3, the shift block 77 is pressed to rotate the arc-shaped movable splint 73 in a direction away from the arc-shaped fixed splint 72, so that the arc-shaped fixed splint 72 and the arc-shaped movable splint 73 are opened, and the water injection pipe 2 is placed in the arc-shaped fixed splint 72 and the arc-shaped movable splint 73. Under the elastic force of the torsion spring 76, the arc-shaped fixed splint 72 and the arc-shaped movable splint 73 clamp and fix the water injection pipe 2, and then the adhesive 9 is pasted on the patient's body to fix the catheter, avoid pulling the catheter and causing the catheter to fall off, and improve the patient's comfort.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
