Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a peritoneal dialysis tubing connection operation chamber. Background Technology

[0002] Peritoneal dialysis is a treatment method that uses the peritoneum as a semi-permeable membrane. Gravity is used to infuse prepared dialysis fluid into the patient's peritoneal cavity through a catheter. The dialysis fluid is continuously replaced to remove metabolic waste products, toxins, and correct water and electrolyte imbalances. Patients undergoing peritoneal dialysis first have a dialysis catheter surgically inserted into their body. The catheter's opening is located outside the body. Dialysis is initiated by connecting the dialysis catheter to the dialysis fluid storage device. During this connection, dust and bacteria from the air can easily enter the body, causing infection and complications such as peritonitis. Therefore, peritoneal dialysis must be performed in a clean, sterilized space. Since peritoneal dialysis typically requires multiple sessions, it significantly restricts the patient's range of motion during treatment, severely impacting their normal work and life.

[0003] Chinese patent (application number: CN201210134197.9) discloses a peritoneal dialysis tubing docking operation chamber, which includes a sealed and visible operation chamber body. The operation chamber body includes a transparent and visible chamber cover and a base that cooperates with the chamber cover. The chamber cover is provided with two operation holes for inserting a hand into the chamber body and two insertion holes for inserting dialysis tubing and dialysate tubing, respectively. A sterilization lamp is provided inside the operation chamber body.

[0004] The patent and existing technologies have the following technical problems in practical use:

[0005] 1. The existing operating chamber, which achieves aseptic adjustment through manual connection in a sealed operating chamber, requires repeated application of iodine solution for disinfection during actual use. This is inconvenient and time-consuming in a sealed operating chamber.

[0006] 2. The existing operating chamber is simply disinfected by wiping with iodine solution, which is prone to missed disinfection and incomplete disinfection. The connection points are easily contaminated during use. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of inconvenient manual connection and easy infection due to incomplete disinfection. This invention provides a peritoneal dialysis tubing connection operation chamber.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0009] A peritoneal dialysis tubing connection operation chamber includes a chamber body, a threaded hole on the right side of the chamber body, an outer frame on the right side of the chamber body, a fixing sleeve inside the outer frame, the fixing sleeve being able to seal and clamp a peritoneal dialysis connector, a threaded connector being threadedly connected inside the threaded hole, the threaded connector being able to rotate automatically, the threaded connector being able to seal and clamp a peritoneal dialysis tubing, an external thread on the outer side of the fixing sleeve, an internal thread on the inner side of the threaded connector, and the external thread being able to threadly connect with the internal thread;

[0010] A medicine container is installed on the outside of the outer frame, and a screw cap is threaded onto the outside of the medicine container. The screw cap is connected to the fixed sleeve through a liquid pipe.

A drive wheel driven by a micro motor is rotatably mounted inside the chamber, and the drive wheel meshes with the gear teeth. A second connecting rod is hinged to the outer side of the connecting ring, and a first connecting rod is movably connected to the end of the second connecting rod away from the connecting ring. The end of the first connecting rod away from the second connecting rod is hinged to the outside of the threaded connector. The first connecting rod and the second connecting rod are arranged in a ring, and can form a sealed cylinder when the first connecting rod and the second connecting rod are closed. A sealed inner liner is provided on the inner side of the first connecting rod and the second connecting rod.

[0012] Furthermore, an elastic connecting piece is provided between the sealing inner liner and the threaded connector.

[0013] Furthermore, the sealed inner liner contains a sealing gas, and the sealed inner liner is connected to the medicine container via a gas pipe.

[0014] Furthermore, a telescopic sliding hole is provided at the end of the second connecting rod away from the connecting ring, and a telescopic rod that can extend and retract is provided inside the telescopic sliding hole, and the telescopic rod is hinged to the first connecting rod.

[0015] Furthermore, a slot is provided at one end of the telescopic rod near the inside of the telescopic sliding hole, and a sliding hole is provided on the inner wall of the telescopic sliding hole. A magnetic block that can be locked in the slot is slidably connected inside the sliding hole. A retaining spring is provided between the magnetic block and the inner wall of the sliding hole.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] like Figures 1-8 As shown, a peritoneal dialysis tubing docking operation chamber includes a chamber body 1. A threaded hole 2 is provided on the right side of the chamber body 1. An outer frame 3 is provided on the right side of the chamber body 1. A fixing sleeve 4 is provided inside the outer frame 3. The fixing sleeve 4 can seal and clamp the peritoneal dialysis connector. A threaded connector 12 is threaded inside the threaded hole 2. The threaded connector 12 can rotate automatically and can seal and clamp the peritoneal dialysis tubing. An external thread is provided on the outside of the fixing sleeve 4. An internal thread is provided on the inside of the threaded connector 12. The external thread can be threadedly connected to the internal thread.

[0034] A medicine container 8 is installed on the outside of the outer frame 3. A screw cap 9 is threadedly connected to the outside of the medicine container 8. The screw cap 9 is connected to the fixed sleeve 4 through the liquid pipe 10.

[0035] In use, the peritoneal dialysis connecting tube is inserted into the threaded connector 12, which seals and clamps the peritoneal dialysis connecting tube. Then, the peritoneal dialysis connecting tube is inserted into the fixing sleeve 4, which seals and clamps the peritoneal dialysis connecting tube. Then, the threaded connector 12 is rotated, and the threaded connector 12 drives the peritoneal dialysis connecting tube to be automatically inserted into the peritoneal dialysis connecting head under the action of the threaded hole 2. The insertion effect is better by rotating the insertion, thus completing the automatic connection without manual operation.

[0036] While plugging in, the threaded connector 12 is threadedly connected to the fixed sleeve 4. The threaded connector 12 and the fixed sleeve 4 form a sealed space, and the connection is located in the sealed space. Then, the iodine in the medicine tank 8 is injected into the sealed space through the liquid pipe 10, which can automatically disinfect the connection. The connection is always sealed and will not be contaminated during use, so it is highly safe to use.

[0037] The screw cap 9 makes it easy to add iodine solution to the medicine container 8, making it convenient to use.

[0038] like Figure 3 , Figure 8 As shown, in some embodiments, a connecting ring 15 is rotatably mounted on the inner wall of the chamber 1, and gear teeth are provided on the outer side of the connecting ring 15. A drive wheel 16 driven by a micro motor is rotatably mounted inside the chamber 1, and the drive wheel 16 meshes with the gear teeth. A second connecting rod 14 is hinged to the outer side of the connecting ring 15. A first connecting rod 13 is movably connected to the end of the second connecting rod 14 away from the connecting ring 15. The end of the first connecting rod 13 away from the second connecting rod 14 is hinged to the outer side of the threaded connector 12. The first connecting rod 13 and the second connecting rod 14 are arranged in a ring. When the first connecting rod 13 and the second connecting rod 14 are closed, they can form a sealed cylinder. A sealed inner liner 17 is provided on the inner side of the first connecting rod 13 and the second connecting rod 14.

[0039] The motor rotates, driving the drive wheel 16 to rotate. The drive wheel 16 drives the connecting ring 15 to rotate via its teeth. The connecting ring 15 drives the second connecting rod 14 to rotate. The second connecting rod 14 drives the first connecting rod 13 to rotate. The first connecting rod 13 drives the threaded connector 12 to rotate. The threaded connector 12 moves under the action of the threaded hole 2, driving the first connecting rod 13 to move. The first connecting rod 13 and the second connecting rod 14 swing inward, squeezing the sealing inner liner 17. The sealing inner liner 17 presses tightly against the peritoneal dialysis connecting tube, thereby making the peritoneum... The dialysis connecting tube is movable. As the threaded connector 12 continues to move, the sealing inner liner 17 becomes increasingly tight, and the friction between it and the peritoneal dialysis connecting tube increases, ensuring stable insertion. When the threaded connector 12 is fully threadedly connected to the fixed sleeve 4, the first connecting rod 13 and the second connecting rod 14 straighten, and the sealing inner liner 17 is sealed to the peritoneal dialysis connecting tube, ensuring that a sealed space can be formed between the threaded connector 12 and the fixed sleeve 4. Therefore, there is no need to separately seal and clamp the peritoneal dialysis connecting tube. Sealing and clamping are performed simultaneously with insertion, resulting in a compact structure and greater ease of use.

[0040] like Figure 5 As shown, in some embodiments, an elastic connecting piece 18 is provided between the sealing inner liner 17 and the threaded connector 12. The sealing performance between the sealing inner liner 17 and the threaded connector 12 is improved by the provision of the elastic connecting piece 18.

[0041] like Figure 2 As shown, in some embodiments, the sealed inner liner 17 contains a sealing gas, and the sealed inner liner 17 is connected to the medicine container 8 through a gas pipe 11.

[0042] During connection, clamp the liquid tube 10 by hand, then control the motor to rotate. The motor drives the drive wheel 16 to rotate, and the drive wheel 16 drives the connecting ring 15 to rotate through its teeth. The connecting ring 15 drives the second connecting rod 14 to rotate, and the second connecting rod 14 drives the first connecting rod 13 to rotate. The first connecting rod 13 drives the threaded connector 12 to rotate, and the threaded connector 12 moves under the action of the threaded hole 2. The threaded connector 12 drives the first connecting rod 13 to move, and the first connecting rod 13 and the second connecting rod 14 swing inward. 14. Squeeze the sealing inner liner 17, which presses tightly against the peritoneal dialysis connecting tube, allowing the peritoneal dialysis connecting tube to move. As the threaded connector 12 continues to move, the sealing inner liner 17 becomes increasingly tight. The sealing gas inside the sealing inner liner 17 enters the medicine container 8 through the gas tube 11. As the gas pressure in the medicine container 8 increases, when the connection is complete, the liquid tube 10 is released, and the iodine in the medicine container 8 is automatically pressed into the sealed space between the threaded connector 12 and the fixed sleeve 4, thus automatically sealing the iodine, making it more convenient to use.

[0043] like Figure 6 As shown, in some embodiments, the end of the second connecting rod 14 away from the connecting ring 15 is provided with a telescopic sliding hole, and a telescopic rod 20 that can extend and retract is provided inside the telescopic sliding hole. The telescopic rod 20 is hinged to the first connecting rod 13.

[0044] With this design, when the connection needs to be disconnected, the telescopic rod 20 extends, and the telescopic rod 20 drives the first connecting rod 13 to swing outward. When the first connecting rod 13 swings, the sealing inner liner 17 expands, and the sealing inner liner 17 expands and draws in air. The sealing inner liner 17 draws in air through the air pipe 11, and the medicine container 8 draws in the excess iodine from the connection. This prevents iodine leakage when the threaded connector 12 separates from the fixed sleeve 4, and also saves on iodine consumption.

[0045] like Figure 2 , Figure 7 As shown, in some embodiments, the telescopic rod 20 has a slot 21 at one end near the inside of the telescopic sliding hole, the inner wall of the telescopic sliding hole has a sliding hole, a magnetic block 22 that can be locked in the slot 21 is slidably connected inside the sliding hole, a retaining spring 23 is provided between the magnetic block 22 and the inner wall of the sliding hole, a storage groove is provided on the inner wall of the compartment 1, a magnetic ring 24 is inserted into the storage groove, the magnetic ring 24 can attract the magnetic block 22, a handle 25 is provided on the left side of the compartment 1, the handle 25 passes through the compartment 1 and is connected to the magnetic ring 24.

[0046] When the connection needs to be disconnected, the magnetic ring 24 is moved by pushing the handle 25. When the magnetic ring 24 moves to the position of the magnetic block 22, the magnetic ring 24 uses magnetic force to drive the magnetic block 22 away from the slot 21. At this time, the telescopic rod 20 can extend and retract, and the sealed inner liner 17 expands under its own elastic force. The expansion of the sealed inner liner 17 causes the first connecting rod 13 to swing, and the first connecting rod 13 causes the telescopic rod 20 to extend. At the same time, the expansion of the sealed inner liner 17 draws in air, and the sealed inner liner 17 draws in air through the air pipe 11, and the medicine container 8 removes excess iodine from the connection. The iodine solution is inhaled into the canister 8, and iodine recovery can be achieved without adding a drive to the telescopic rod 20. Then, by pulling the handle 25 to reset the magnetic ring 24, the drive wheel 16 is rotated, causing the threaded connector 12 to separate from the fixed sleeve 4. At the same time, when the threaded connector 12 is fully reset, it automatically presses the telescopic rod 20 into the second link 14 through the first link 13. The magnetic locking block 22 is engaged in the slot 21 under the action of the retaining spring 23, and the telescopic rod 20 is locked again. This does not affect the next sealing clamping and insertion, making it convenient to use.

[0047] like Figure 7 As shown, in some embodiments, the magnetic card block 22 is designed to be tilted on the side near the first connecting rod 13, which facilitates the magnetic card block 22 to be engaged in the card slot 21.

[0048] like Figure 2 As shown, in some embodiments, the vertical distance between the handle 25 and the compartment 1 is the same as the vertical distance between the magnetic ring 24 and the magnetic block 22, so that when the handle 25 is pushed completely to the outside of the compartment 1, the magnetic ring 24 just moves to the position of the magnetic block 22, which is convenient to control.

[0049] like Figure 1 As shown, in some embodiments, a sealing sleeve 5 is provided on the right side of the fixing sleeve 4. The sealing sleeve 5 is made of rubber, and a locking sleeve 6 is fitted on the outside of the sealing sleeve 5. A locking bolt 7 is threadedly connected to the opening of the locking sleeve 6. With this design, the sealing sleeve 5 can be sealed and clamped on the peritoneal dialysis connector by simply rotating and tightening the bolt 7, which is convenient to use.

[0050] like Figure 5 As shown, in some embodiments, a sealing ring 19 is provided on the inner side of the threaded connector 12 to improve the sealing performance of the connection between the threaded connector 12 and the fixed sleeve 4.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
