Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a peritoneal dialysis assembly. Background Art

[0002] Peritoneal dialysis (PD) is a method for treating renal failure, especially when the kidneys can no longer effectively filter the blood. It uses the body's own peritoneum (a membrane that covers the inner wall of the abdominal cavity and abdominal organs) as a semi-permeable membrane for the dialysis process. In peritoneal dialysis, dialysis fluid is introduced into the abdominal cavity and then allowed to stay for a period of time so that waste products and excess water in the blood can pass through the peritoneum into the dialysis fluid, and then the dialysis fluid containing waste products is drained out of the body.

[0003] The key components commonly used in the process of peritoneal dialysis mainly include the following parts:

[0004] - Intra-abdominal permanent tube: This part of the pipeline is implanted inside the patient's abdominal cavity and is usually not withdrawn. When the pipeline needs to be maintained due to wear, a small section can be cut short for continued use, ensuring long-term dialysis needs.

[0005] - External short tube: This is a component that needs to be replaced regularly, about once every six months. Its main function is to serve as a temporary connection bridge between the intra-abdominal permanent tube and the dialysis solution and excrement bag during each dialysis process.

[0006] - Catheter: It is used to connect the dialysis solution and the excrement bag to ensure the input of dialysis fluid and the discharge of waste fluid.

[0007] Currently, the connection between the external short tube and the intra-abdominal permanent tube, and between the external short tube and the catheter mainly relies on a screw fixation structure.

[0008] For patients, each dialysis takes a relatively long time to complete. During the long dialysis process, patients will perform physical actions such as sleeping and turning over. These physical actions will cause the connection between the external short tube and the intra-abdominal permanent tube, and between the external short tube and the catheter to become loose or fall off.

[0009] If an accidental detachment occurs, it may cause contamination in the abdominal cavity. If not discovered and treated in time, there is a high risk of triggering peritonitis, a life-threatening complication.

[0010] Therefore, there is an urgent need to develop a peritoneal dialysis assembly to solve the above technical problems. Summary of the Invention

[0011] The object of the present invention is to provide a peritoneal dialysis assembly to solve the technical problems in the prior art that the peritoneal dialysis time is relatively long, and the external short tube connected by a spiral fixing structure is prone to looseness or detachment from the intraperitoneal permanent tube or the external short tube is prone to looseness or detachment from the catheter.

[0040] The following will further describe the present application in detail with reference to the Figures 1 - 5 accompanying drawings. An embodiment of the present application discloses a peritoneal dialysis assembly.

[0041] Referring to Figure 1 and Figure 2 as shown, a peritoneal dialysis assembly includes a first connector 110, a second connector 120, and a connection assembly. When used for connecting a permanent tube and a semi-permanent tube, the first connector 110 is used to connect the permanent tube, and the second connector is used to connect the semi-permanent tube. When used for connecting a semi-permanent tube and a catheter, the first connector 110 is used to connect the semi-permanent tube, and the second connector 120 is used to connect the catheter. The first connector 110 and the second connector 120 are sleeved and thread-fixed, that is, the second connector 120 is sleeved outside the first connector 110. And an inner cavity for liquid to pass through is provided in both the first connector 110 and the second connector 120, and the inner cavities communicate with the connected permanent tube, semi-permanent tube, or catheter. The connection assembly is disposed between the first connector 110 and the second connector 120 to connect the first connector 110 and the second connector 120, thereby increasing the connection strength between the first connector 110 and the second connector 120.

[0042] Referring to Figure 3 and Figure 4 as shown, the connection assembly includes a convex block 350 and a sleeve 310. The convex block 350 is fixedly connected to the outer circumferential side wall of the first connector 110, and the number of convex blocks 350 can be increased according to actual situations. The sleeve 310 is used to be sleeved outside the second connector 120 and the first connector 110 in sequence from one end of the second connector 120.

[0043] During the installation process, the sleeve 310 is preferably sleeved on the semi-permanent tube or catheter connected to the second connector 120 first, and then the second connector 120 is fixedly connected to the semi-permanent tube or catheter. A slot 380 is formed through the side wall of one end of the sleeve 310 in the radial direction, and a positioning ring 320 is fixedly connected to the end of the other end of the sleeve 310.

[0044] During the connection process, the sleeve 310 is pushed to be sleeved on the second connector 120 and the first connector 110 so that the protrusion 350 is clamped in the clamping groove 380 , and at the same time, the positioning ring 320 abuts against the end of the second connector 120 away from the first connector 110 .

[0045] The sleeve 310 is used to complete the sleeve connection between the first connector 110 and the second connector 120. Therefore, the sleeve connection of the sleeve 310 can prevent the first connector 110 and the second connector 120 from reducing external contact during use, thereby preventing the first connector 110 and the second connector 120 from loosening or falling off.

[0046] The limiting and fixing of the sleeve 310 in the axial and radial directions further enhances the connection relationship between the first connector 110 and the second connector 120 , thereby ensuring the stability of the first connector 110 and the second connector 120 .

[0047] Reference Figure 3 and Figure 4 As shown, the connection assembly further includes a pressing plate 330, one end of which is fixedly connected to the outer circumferential side wall of the sleeve 310, the pressing plate 330 is tilted, and the other end of the pressing plate 330 is fixedly connected to a pressing block 340 for aligning with the slot 380. During use, the pressing plate 330 squeezes one end of the pressing block 340 connected thereto, and presses it into the slot 380 to push the protrusion 350 out of the slot 380, thereby realizing the detachment of the sleeve 310 from the first connector 110.

[0048] During the connection process between the first connector 110 and the second connector 120, the protrusion 350 has a guide surface 360 ​​inclined toward one end of the second connector 120. The guide surface 360 ​​is inclined from low to high along the insertion direction of the sleeve 310 when the sleeve 310 is sleeved. During the process of inserting the sleeve 310, the guide surface 360 ​​of the protrusion 350 contacts the inner wall of the sleeve 310, thereby facilitating the sleeve 310 to pass through the protrusion 350 and facilitating the protrusion 350 to be clamped in the slot 380.

[0049] A vertical surface 370 is provided at one end of the protrusion 350 facing away from the first connector 110 and the second connector 120. The vertical surface 370 is perpendicular to the length direction of the first connector 110, and when the protrusion 350 is clamped in the slot 380, the vertical surface 370 abuts against the side wall of the slot 380 in the axial direction of the sleeve 310 away from the positioning ring 320.

[0050] The protrusion 350 is provided with a compression cavity 390 that is disengaged from the slot 380 under external force. The compression cavity 390 is opened through the first connector 110 in the radial direction, and an opening is provided at the vertical surface 370 of the first connector 110 for squeezing air.

[0051] When the pressing block 340 presses against the top surface of the convex block 350, the two side walls of the compression cavity 390 are attached to each other, thereby facilitating the detachment of the convex block 350 from the card slot 380.

[0052] Referring Figure 1 and Figure 5 As shown, the connecting component further includes a protective box 200 for accommodating the first connector 110 and the second connector 120. The protective box 200 is formed by splicing the upper box body 220 and the lower box body 210, and fixing ears 230 facilitating their separation are fixedly connected to the side walls of the protective box 200. The protective box 200 is provided with two communication holes for the permanent tube, semi-permanent tube or catheter to pass through. The two communication holes are arranged opposite to each other. When the first connector 110 is arranged in the protective box 200, the end of the first connector 110 and the end face of the positioning ring 320 abut against the inner wall of the protective box 200. In this way, the limiting of the two connectors in the protective box 200 is realized.

[0053] Two buckles 270 are fixedly connected to the lower box body 210, and the two buckles 270 are correspondingly clamped on the first connector 110 and the sleeve 310. One buckle 270 is fixed on the upper box body 220 for fixedly connecting the sleeve 310. When the upper box body 220 and the lower box body 210 are spliced with each other, the buckles 270 respectively sleeve and fix the first connector 110 and the sleeve 310.

[0054] In this way, the fixation of the first connector 110 and the second connector 120 in the protective box 200 is realized. The buckles 270 are all provided with arc-shaped grooves 280, and the arc-shaped grooves 280 facilitate the embedding of the first connector 110 and the sleeve 310. A silicone layer 290 is arranged on the inner wall of the arc-shaped sleeve 310, and the silicone layer 290 fits against the first connector 110 and the sleeve 310 being clamped, thereby preventing the first connector 110 and the sleeve 310 from sliding when embedded in the arc-shaped groove 280.

[0055] Referring Figure 5 As shown, a humidity sensor 260 is fixedly installed on the inner wall of the upper box body 220. A controller 240 is fixedly connected to the top surface of the outer wall of the protective box 200, and the controller 240 is electrically connected to the temperature sensor. An alarm 250 is also fixedly connected to the top surface of the outer wall of the protective box 200, and the alarm 250 is electrically connected to the controller 240.

[0056] The humidity sensor 260 is used to detect whether there is liquid inside the protective box 200 and transmit the detection data to the controller 240. The controller 240 can set a preset threshold. When the data detected by the humidity sensor 260 exceeds the preset threshold, the controller 240 controls the alarm 250 to give an alarm to remind the medical staff.

[0057] Among them, the protective box 200 is made of a transparent material, so as to facilitate the observation of the internal environment of the protective box 200.

[0058] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
