[0025] The present invention provides a gastrointestinal catheter fixer, comprising a sliding seat 101, an adhesive component 102 and a fixing component 103, wherein the fixing component 103 comprises a housing 104, a rotating ring 105, a push rod 106, a driving seat 107, a clamping seat 108 and a reset member 109, wherein the clamping seat 108 comprises a bracket 110, a clamping block 111 and a roller 112, wherein the reset member 109 comprises a slider 113 and a reset spring 114, wherein the housing 104 has a guide groove 118, and the push rod 106 comprises a threaded rod 115, a threaded sleeve 116 and a friction spring 114. The wiping pad 117 pushes the push rod 106 to move, so that the push rod 106 drives the rotating ring 105 to rotate, and the rotating ring 105 drives the multiple driving seats 107 to move, and the driving seats 107 drive the corresponding clamping seats 108 to move, so that the clamping seats 108 clamp and fix the gastrointestinal catheter, thereby achieving the purpose of fixing gastrointestinal catheters of different specifications. It can be understood that the above-mentioned scheme can be used when fixing gastrointestinal catheters of different specifications, and can also be used to flexibly adjust the position of the shell 104.

[0026] According to this specific embodiment, the adhesive component 102 is disposed on the sliding seat 101 , and the adhesive component 102 can be fixed on the patient's body.

[0027] The housing 104 is fixedly connected to the sliding seat 101 and is arranged on the sliding seat 101; the rotating ring 105 is rotatably connected to the housing 104 and is located inside the housing 104; the push rod 106 is connected to the rotating ring 105 and is located on one side of the rotating ring 105; the driving seat 107 is fixedly connected to the rotating ring 105 and is located inside the rotating ring 105; the clamping seat 108 is slidably connected to the housing 104 and abuts against the driving seat 107 and is arranged on the housing 104; the reset member 109 is arranged on the housing 104; the driving seat 107, the clamping seat 108 and the reset member 109 are all provided in plurality; the driving seat 107 is provided with an inclined surface; the reset member 109 is elastic; the housing 104 The invention is ring-shaped; when in use, the sliding seat 101 and the shell 104 are fixed to the patient's limbs or trunk through the bonding component 102, and then the gastrointestinal catheter is passed through the shell 104, and the push rod 106 is pushed to move, so that the push rod 106 drives the rotating ring 105 to rotate, and the rotating ring 105 drives the multiple driving seats 107 to rotate. Since the driving seat 107 is provided with an inclined surface, the rotation of the driving seat 107 can drive the clamping seat 108 to move, and then the multiple clamping seats 108 move synchronously and abut the surface of the gastrointestinal catheter, so as to complete the fixation of the gastrointestinal catheter. The present invention drives the clamping seat 108 to move by the driving seat 107, so that the clamping seat 108 can move different distances, and then fix gastrointestinal catheters of different specifications, thereby increasing the applicability of the device.

[0028] Secondly, the bracket 110 is slidably connected to the shell 104 and is arranged on the shell 104; the clamping block 111 is fixedly connected to the bracket 110 and is located on one side of the bracket 110; two brackets 110 are provided, and are respectively located on both sides of the clamping block 111, and the inner side of the clamping block 111 is arc-shaped, and the gastrointestinal catheter is clamped and fixed by multiple clamping blocks 111.

[0029] At the same time, the roller 112 is rotatably connected to the bracket 110, abuts against the drive seat 107, and is arranged on the bracket 110; the roller 112 is located between the two brackets 110, and the rotation of the roller 112 reduces the friction between it and the drive seat 107, so that the medical staff can rotate the rotating ring 105 more smoothly.

[0030] In addition, the shell 104 has a guide groove 118, and the slider 113 is slidably installed inside the guide groove 118 and fixedly connected to the bracket 110; the two ends of the reset spring 114 are respectively connected to the slider 113 and the shell 104, and the slider 113 is arranged in the guide groove 118; when the driving seat 107 drives the roller 112 to move, the roller 112 drives the bracket 110 and the clamping block 111 to move, and the bracket 110 moves while driving the slider 113 to move, so that the slider 113 squeezes the reset spring 114, so that after the rotating ring 105 and the driving seat 107 are reset, the slider 113, the bracket 110, the clamping block 111 and the roller 112 can be reset under the action of the reset spring 114, so that it is convenient for medical staff to pass the gastrointestinal catheter through the shell 104.

[0031] Then, the threaded rod 115 is fixedly connected to the rotating ring 105 and is located on one side of the rotating ring 105; the threaded sleeve 116 is threadedly connected to the threaded rod 115 and is sleeved on the threaded rod 115; when the clamp 111 abuts the gastrointestinal catheter, the medical staff rotates the threaded sleeve 116 to move the threaded sleeve 116 on the threaded rod 115 and then abut the shell 104. At this time, the threaded rod 115 is fixed by the friction between the threaded sleeve 116 and the shell 104, and then the rotating ring 105 is locked and fixed to prevent the rotating ring 105 from rotating at will, resulting in loose clamping of the gastrointestinal catheter.

[0032] Finally, the friction pad 117 is fixedly connected to the threaded sleeve 116 and is located on the side of the threaded sleeve 116 close to the outer shell 104; the friction between the threaded sleeve 116 and the outer shell 104 is increased by the friction pad 117, thereby improving the locking effect of the threaded rod 115 and the rotating ring 105.

[0033] When the gastrointestinal catheter fixer of this embodiment is used, the sliding seat 101 and the shell 104 are fixed to the patient's limbs or trunk through the bonding component 102, and then the gastrointestinal catheter is passed through the shell 104, and the threaded sleeve 116 and the threaded rod 115 are pushed to move, and the threaded rod 115 drives the rotating rod to rotate, thereby driving the multiple driving seats 107 to rotate, so that the driving seats 107 drive the corresponding rollers 112 to move, and the rollers 112 drive the bracket 110 and the slider 113 to move, so that the multiple clamping blocks 111 are aligned with the gastrointestinal catheter. The surface of the catheter abuts, thereby completing the clamping and fixing of the gastrointestinal catheter; after the fixation is completed, the medical staff rotates the threaded rod 115 to move the threaded rod 115 on the threaded sleeve 116, thereby driving the friction pad 117 to move, so that the friction pad 117 abuts against the shell 104, thereby fixing the threaded rod 115 and the threaded sleeve 116, locking the rotating ring 105, preventing the rotating ring 105 from rotating and causing the fixation of the gastrointestinal catheter to loosen, thereby achieving the purpose of fixing gastrointestinal catheters of different specifications and improving the applicability of the device.
