Description

Technical Field

[0001] The invention relates to the technical field of extracorporeal pipeline positioning, in particular to a clinical peritoneal dialysis positioner for nephrology. Background Art

[0002] Peritoneal dialysis is an important treatment for end-stage renal disease. Its operational convenience and tubing fixation directly affect the patient's treatment experience and safety. Currently, in clinical practice, after the peritoneal dialysis tube is implanted into the abdominal cavity through the abdominal wall, the external segment of the tube is generally fixed by directly adhering it to the skin surface with medical tape at the point where the dialysis tube passes through the skin near the abdominal wall, forming a single-point fixation. This fixation method has significant drawbacks: The extracorporeal tubing lacks effective support: The extracorporeal tubing is typically 20-30 cm long. Except for the tape fixation point near the abdominal wall, the remaining long tubing is suspended in the air. During daily activities (such as walking, turning over, washing, etc.), the tubing can shake and be pulled by gravity or body movement, which can easily lead to the following problems: Local skin irritation: The tape fixing point is subjected to repeated pulling, which may cause skin friction damage, redness, swelling, or even ulceration; Risk of tube displacement: The shaking tube may cause the internal segment to shift, causing complications such as poor dialysis fluid drainage and abdominal pain; Subjective discomfort of patients: The pulling sensation caused by the shaking of the tubes or the foreign body sensation caused by friction with clothing seriously affects the patient's freedom of movement and quality of life. To reduce the chances of problems caused by the above defects, patients are fixed by wrapping the tube with gauze, tying it with rubber bands, or simply folding and rolling the tube around the abdomen. Such operations carry multiple risks: Mechanical damage to the pipeline: entanglement or folding may cause local compression and deformation of the pipeline, increasing the risk of lumen stenosis and blockage; Increased risk of infection: Non-sterile materials or improper operation can easily lead to bacterial growth at the skin contact site, increasing the probability of infectious complications such as peritonitis; Reduced operational convenience: The rolled-up tubing needs to be repeatedly unfolded during dialysis connection, dressing change, and other operations, which increases the difficulty of operation for medical staff and prolongs the operation time.

DETAILED DESCRIPTION

[0019] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0020] The following is a further description with reference to the accompanying drawings and specific embodiments: In order to effectively fix the extracorporeal peritoneal dialysis tube, this embodiment provides a positioning device for the extracorporeal tube. Under the action of the positioning device, its ability to resist dragging is enhanced, and the remaining extracorporeal tube can be stored on the positioning device, reducing the chance of discomfort.

[0021] like Figure 1 Specifically, the positioning device comprises a waist belt 1 and a positioning assembly 2. The positioning assembly 2 is positioned directly opposite the dialysis holes in the abdomen and adheres to the abdominal skin. The waist belt 1 is worn around the patient's waist, with one end of the belt 1 detachably connected to the positioning assembly 2. The other end of the belt 1 is not only detachably connected to the positioning assembly 2, but also retractable to adjust its tightness, thereby increasing the stability of the positioning assembly 2 relative to the abdomen.

[0022] like Figure 4As shown, in order to enhance the drag resistance of the extracorporeal tube through the positioning component 2 and to enable the storage and handling of the extracorporeal tube, the positioning component 2 includes a hydrogel layer 23, a main board 21, and a storage plate 22, which are sequentially distributed and each of which has a hole in the middle. The main board 21 and the storage plate 22 are both made of a bendable material (such as a rubber material), and the main board 21 is in contact with the hydrogel layer 23, while the storage plate 22 is detachably mounted on the main board 21. When the positioning component 2 is applied to the abdomen, the extracorporeal tube is first passed through the hole of the positioning component 2, and then the hydrogel layer 23 is in contact with the abdominal skin, and finally the remaining extracorporeal tube is embedded in the storage plate 22. The multiple bending distribution of the extracorporeal tube increases the resistance to movement relative to the storage plate 22, and while the extracorporeal tube is stably installed, its shaking and discomfort are avoided.

[0023] like Figure 7 As shown, specifically, the side of the storage plate 22 away from the main board 21 is provided with at least three slots 221 distributed up and down, and one of the slots 221 is connected to the channel of the positioning component 2. In addition, the slots 221 are provided along the length direction of the storage plate 22 and are both set to be open, and the central angle of the end face of the slot 221 is greater than 180°, and the inner diameter of the slot 221 is equal to the outer diameter of the extracorporeal tube. After the peritoneal dialysis is completed, the extracorporeal tube is buckled into the slot 221. When the extracorporeal tube needs to be buckled from one slot 221 to another slot 221, it can be embedded in the slot 221 after bending the extracorporeal tube. Repeat the above operation to embed the extracorporeal tube in multiple slots 221, so as to realize the storage and processing of the extracorporeal tube without affecting the patient's next peritoneal dialysis treatment.

[0024] like Figure 5 、 Figure 8 As shown, to removably mount the receiving plate 22 on the main board 21, a second snap groove 212 and a third snap plate 222 are respectively provided on the adjacent side walls of the main board 21 and the receiving plate 22. Both the second snap groove 212 and the third snap plate 222 are convex structures and are located at the end corners of the side surfaces. To facilitate the stable mounting of the receiving plate 22 on the main board 21, the two second snap grooves 212 located on the same straight line of the main board 21 are both open at their ends that are away from each other. The main board 21 is longer than the receiving plate 22. Therefore, when assembling the main board 21 and the receiving plate 22, the main board 21 needs to be bent to shorten the distance between the two second snap grooves 212 located on the same straight line, thereby allowing the third snap plates 222 to be mounted within their respective second snap grooves 212.

[0025] like Figure 5 、 Figure 6As shown, to further enhance the stability of the extracorporeal tube's installation relative to the positioning assembly 2, the apertures between the main plate 21 and the hydrogel layer 23 are configured as countersunk holes 213. The size of the countersunk hole 213 at one end near the receiving plate 22 is smaller than that at the other end. An annular airbag 24 is positioned within the countersunk hole 213, and an annular baffle 242 is located at the rear end of the annular airbag 24. The baffle 242 is positioned at the larger end of the countersunk hole 213. The structural characteristics of the countersunk hole 213, the annular airbag 24, and the baffle 242 ensure a stable installation of the annular airbag 24 when the hydrogel layer 23 is attached to the abdominal skin. Furthermore, a valve core 241 is located at the front end of the annular airbag 24. This valve core 241 houses a one-way valve structure. During inflation, an air needle is inserted into the valve core, opening the one-way valve and allowing gas to enter the annular airbag 24. When the air needle is removed, the one-way valve resiliently seals, preventing gas leakage. When the extracorporeal tube passes through the annular airbag 24 , there is a large friction coefficient between the extracorporeal tube and the annular airbag 24 , which increases the resistance to the movement of the extracorporeal tube.

[0026] like Figure 2 、 Figure 5 As shown, in order to stably install the belt 1 on the main board 21, a first snap plate 13 is hingedly provided at one end of the belt 1, and a second snap plate 18 is hingedly provided at the other end. First snap grooves 211 are provided in the middle of the two vertical edges of the side walls of the main board 21 adjacent to the storage plate 22. The first snap plates 13 are installed in the first snap grooves 211 to achieve a stable connection between the belt 1 and the main board 21. The retractable feature of the belt 1 is utilized to force the main board 21 and the hydrogel layer 23 to be stably fitted to the abdomen.

[0027] like Figure 2 As shown, specifically, the second snap plate 18 and the end of the belt 1 are fixedly provided with a third end tube 17 and a second end tube 16 respectively, the third end tube 17 is arranged between the two second end tubes 16, and the third end tube 17 and the second end tube 16 are sleeved on the same axis to realize the hinged connection between the second snap plate 18 and the belt 1.

[0028] like Figure 2 As shown, in order to achieve a hinged connection between the first snap plate 13 and the belt 1 and to enable the belt 1 to be retracted, two ear plates 15 are fixedly disposed above and below the ends of the first snap plate 13. A plum blossom column 14 is provided through the two ear plates 15. A first end tube 11 is fixedly disposed at the end of the belt 1, and a first plum blossom hole 12 is provided through the first end tube 11. The plum blossom column 14 is provided through the first plum blossom hole 12 and can be rotated to retract the belt 1 under the action of an external force. That is, after the belt 1 is worn around the waist, the patient can rotate the plum blossom column 14 to achieve the retraction and expansion of the belt 1.

[0029] like Figure 3As shown, in order to keep the waist belt 1 in a stable state after being retracted and extended, a top plate 141 is fixedly provided on the portion of the plum blossom column 14 protruding from the upper ear plate 15. Under the action of this top plate 141, the plum blossom column 14 is stably mounted on the ear plate 15. In addition, a rotating column 142 is sleeved on the top plate 141. The top of the plum blossom column 14 is inserted into the second plum blossom hole 144 of the rotating column 142. A plug-in column 143 is fixedly provided at the bottom of the rotating column 142. The middle part of the plug-in column 143 is provided with a rubber layer. Therefore, the plug-in column 143 can be inserted into the plug-in slot 151 of the ear plate 15 to achieve a stable connection between the rotating column 142 and the ear plate 15. This also provides support for the patient to remove the plug-in column 143 to release the restriction of the rotating column 142 and realize the retraction and extension of the waist belt 1.

[0030] The above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
