Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary positioning structure for peritoneal dialysis tubing. Background Technology

[0002] Peritoneal dialysis involves using gravity to regularly and periodically infuse prepared dialysis fluid into the patient's peritoneal cavity through a catheter. Therefore, peritoneal dialysis requires the use of tubing to connect the tubing to the peritoneal dialysis equipment. The tubing is then inserted into the patient's body to enable peritoneal dialysis. When the tubing is inserted into the patient's body, a tubing positioning structure is used to fix the tubing to the body, ensuring the stability of the peritoneal dialysis process.

[0003] According to CN202323496022.5, this utility model relates to the field of tubing fixation technology, specifically disclosing a dialysis tubing fixation clip, including: a clamping plate, which is installed on the bed rail; and a fixing mechanism, which is installed on the clamping plate. The fixing mechanism fixes the tubing to the clamping plate. Through the disposable clamping plate and fixing mechanism, the bed rail and the tubing are relatively fixed. On the one hand, while ensuring the tubing is unobstructed, the tubing can be fixed, reducing the possibility of tubing loosening, slippage, and needle dislodgement. On the other hand, the clamping plate and fixing mechanism are made of disposable materials and can be discarded after use without the need for further disinfection, thus facilitating use by medical staff.

[0004] However, tubing positioning devices typically use clamps to support the tubing, and these clamps are generally fixed to the positioning device. Since the positioning device needs to be worn on the patient's body, its position may shift each time it is worn. When the tubing is installed on the clamps, this can easily lead to deviations in the tubing's fixed position, thus affecting the normal use of the tubing during peritoneal dialysis. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention employs a positioning and wearing mechanism, which allows the positioning structure to be worn on the patient's body by wrapping a positioning elastic band around the body and using the hook and loop sides of the Velcro. This facilitates the positioning structure's positioning of the tubing. When it is difficult to wrap the positioning elastic band around the patient's body, the positioning structure can be directly worn on the patient's body using a positioning adhesive, ensuring the versatility of the positioning structure's wearing method. The appropriate wearing method can be selected according to the clinical patient's condition, ensuring the smooth progress of peritoneal dialysis.

[0017] Furthermore, by employing an angle positioning mechanism, the angle panel can be rotated while simultaneously being fixed at any angle, facilitating the adjustment of the overall positioning direction of the pipeline. The pipeline fixing clamp can also be rotated independently, and this rotation causes a portion of the pipeline to rotate to adjust its positioning direction. This adjustment is made according to the angle required for peritoneal dialysis pipelines, avoiding the problem of difficulty in adjusting the pipeline positioning direction affecting pipeline transmission. This ensures that the pipeline can be used normally under any circumstances when the positioning structure is worn. Attached Figure Description

The main positioning hole 7 is located between the positioning body 1 and the angle panel 3. Multiple sets of tubing fixing clamps 15 are provided, each rotating on the front end face of the angle panel 3.

[0033] The positioning and wearing mechanism also includes: a positioning adhesive 6; there are two sets of positioning adhesive 6, which are respectively bonded to the inner end faces of two sets of positioning telescopic belts 4 and respectively bonded to the patient. The two sets of positioning adhesive 6 are rectangular structures.

During use, the adjusting sliders 14 slide, causing the adjusting friction blocks 1402 to slide. The adjusting friction blocks 1402 slide to the upper side of the pipe connection plates 13, thereby fixing the rotation direction of the pipe fixing clamp 15 by adjusting the friction between the adjusting friction blocks 1402 and the pipe connection plates 13.

[0042] The specific usage and function of this embodiment two: During use, the angle connecting cylinder 8 and the limiting protrusion 801 are inserted into the positioning body 1. The angle connecting cylinder 8 can rotate inside the positioning body 1. The spring 901 forces the limiting slider 9 to slide, which in turn causes the limiting friction block 902 to slide.

The angle connecting cylinder 8 is fixed in position, thus fixing the rotation position of the angle panel 3. The operator turns the tubing fixing clamp 15 to rotate, causing the tubing shaft 12 to rotate. The rotation of the tubing shaft 12 causes the tubing connecting plate 13 to rotate. The dialysis tubing is locked inside the tubing fixing clamp 15. The tubing fixing clamp 15 causes the dialysis tubing to rotate, adjusting the angle position of the dialysis tubing. The elastic force of the adjusting spring 1401 causes the adjusting slider 14 to slide. The adjusting slider 14 slides inside the angle panel 3. The sliding of the adjusting slider 14 causes the adjusting friction block 1402 to slide. The adjusting friction block 1402 slides to the upper side of the tubing connecting plate 13. By adjusting the friction between the adjusting friction block 1402 and the tubing connecting plate 13, the rotation direction of the tubing fixing clamp 15 is fixed, thus achieving the adjustment of the fixed angle of the dialysis tubing.
