Description

Technical Field

[0001] The invention relates to the technical field of peritoneal dialysis, and in particular to a peritoneal dialysis fluid exchange device. Background Art

[0002] Peritoneal dialysis (PD) uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through a catheter. Due to the concentration gradient difference of the solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); and the water moves from the low-osmotic side to the high-osmotic side (osmotic effect). The peritoneal dialysate is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance.

[0003] Because peritoneal dialysis treatment is simple to operate, patients can undergo peritoneal dialysis treatment alone. When patients undergo peritoneal dialysis treatment alone, they often need to connect the catheter on the dialysis bag to the dialysis tube on the human body in a disinfected and sterilized room to prevent bacterial infection and peritonitis in the patient. Heating equipment is needed to heat the dialysate to the required temperature, usually body temperature or slightly higher than body temperature (for example, 37°C to 38°C). The heater will ensure that the dialysate maintains a constant temperature before being injected into the abdominal cavity to prevent chills or discomfort in the body. However, when patients need treatment outside, they may not always have the rooms or equipment required for the above treatment conditions, which causes great trouble to patients who need dialysis treatment.

[0004] Therefore, we proposed a peritoneal dialysis fluid exchange device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 5A peritoneal dialysis fluid exchange device includes an isolation box 1, and the isolation box 1 can store items required for dialysis treatment such as dialysis fluid bags, disposable medical gloves, and iodine caps. Connecting pipes 2 are provided at both ends of the isolation box 1, and the two connecting pipes 2 pass through the two ends of the isolation box 1 and are fixedly connected thereto. A symmetrically arranged clamping mechanism is provided at both ends of the two connecting pipes 2, and the clamping mechanism includes a first support plate 3, and a clamping block 4 is provided between the first support plate 3 and the connecting pipe 2. A sliding column 5 is fixedly connected to one end of the clamping block 4 close to the first support plate 3. The sliding column 5 passes through the first support plate 3 and is slidably connected thereto. A slot 6 is provided on the cylindrical surface of the sliding column 5, and a first spring 7 is sleeved on the sliding column 5. One end of the first spring 7 is fixedly connected to the clamping block 4 and the other end is fixedly connected to the first support plate 3. An extension plate 8 is fixedly connected to the cylindrical surface of the sliding column 5, and the extension plate 8 and the clamping block 4 are fixed together. A limit rod 9 is connected, which passes through the first support plate 3 and is slidably connected thereto. An end of the first support plate 3 away from the clamping block 4 is fixedly connected to a second support plate 11. An end of the second support plate 11 away from the sliding column 5 is provided with a pulling block 13. An end of the pulling block 13 close to the second support plate 11 is fixedly connected to two sliding rods 12. Both sliding rods 12 pass through the second support plate 11 and are slidably connected thereto. An insert block 14 is fixedly connected between the two sliding rods 12. An end of the insert block 14 close to the second support plate 11 is fixedly connected to a second spring 15. An end of the second spring 15 away from the insert block 14 is fixedly connected to the second support plate 11. A pull ring 10 is fixedly connected to one end of the sliding column 5 away from the clamping block 4. In the initial state, each clamping block 4 is fitted with the corresponding connecting pipe 2 due to the elastic force of the corresponding first spring 7, and the plug block 14 is pressed against the sliding column 5 and frictionally fitted therewith due to the elastic force of the second spring 15. When in use, the pull ring 10 is pulled in the direction away from the connecting pipe 2, and the sliding column 5 slides in the direction away from the connecting pipe 2 and drives the clamping block 4 to move in the direction away from the connecting pipe 2. The clamping block 4 compresses the corresponding first spring 7 in the direction of the corresponding first supporting plate 3, and the plug block 14 pressed against the sliding column 5 rubs against the sliding column 5 until the slot 6 on the sliding column 5 rises to the position of the corresponding plug block 14. The plug block 14 is inserted into the corresponding slot 6 due to the elastic force of the second spring 15. At this time, the pull ring 10 is released, thereby separating and fixing the clamping block 4 from the corresponding connecting pipe 2. When each sliding column 5 slides, the corresponding limit rod 9 slides synchronously and limits it to prevent the corresponding clamping block 4 from rotating and deviating.After each clamping block 4 is separated from the corresponding connecting pipe 2 and fixed in this way, the disposable medical gloves are taken out and respectively extended into the isolation box 1 through the two connecting pipes 2. The sleeve parts of the two disposable medical gloves are turned outward and respectively sleeved on the outer side walls of the two connecting pipes 2. Then, the pulling blocks 13 in each clamping mechanism are pulled in the direction away from the sliding column 5, so that each plug-in block 14 is pulled out of the corresponding slot 6. After there is no block 14 stuck, each clamping block 4 is clamped to the corresponding connecting pipe 2 due to the elastic force of the corresponding first spring 7. After releasing the pulling block 13, the corresponding plug-in block 14 returns to the initial state due to the elastic force of the second spring 15 and presses against the corresponding sliding column 5 and frictionally fits with it. Through the clamping blocks 4 in each clamping mechanism, the sleeve parts of the two disposable medical gloves that are turned outward and sleeved on the outer side walls of the two connecting pipes 2 are fixedly clamped on the two connecting pipes 2. After that, the operator can put both hands into the two fixed disposable medical gloves through the two connecting pipes 2 and operate in the isolation box 1.

[0026] The upper end of the isolation box 1 is rotatably connected to a cover plate 16, and a protruding block 17 is fixedly connected to the front end of the cover plate 16.

After closing the cover plate 16, turning on the ultraviolet lamp 33 can irradiate and disinfect the interior of the isolation box 1 and the items stored therein. The observation window 18 is convenient for the user to operate by viewing the interior of the isolation box 1 through the observation window 18.

[0027] The rear end of the isolation box 1 is fixedly connected to a second fixed rod 22, and the end of the second fixed rod 22 away from the isolation box 1 is rotatably connected to a damping ring 23, and the end of the damping ring 23 away from the second fixed rod 22 is fixedly connected to a rotating stopper 24. The rear end of the isolation box 1 is fixedly connected to two rectangular blocks 25 correspondingly arranged on the left and right, and a rotating rod 26 is rotatably connected between the two rectangular blocks 25. The cylindrical surface of the rotating rod 26 is fixedly connected to a movable plate 27, and the end of the movable plate 27 close to the isolation box 1 is fixedly connected to a heating box 28. In the initial state, Figure 2 As shown, the upper end of the heating box 28 is against the rear end of the isolation box 1, and the rotating block 24 is longitudinal, and the rotating block 24 will not rotate due to the damping ring 23 without external force, thereby clamping the movable plate 27.
