Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a peritoneal dialysis waste bag treatment device. Background Art

[0002] Peritoneal dialysis is a treatment for chronic kidney failure. It uses the peritoneum as a semi-dialysis membrane, injecting dialysate into the peritoneal cavity to remove waste and excess water from the body, thereby maintaining electrolyte and acid-base balance.

[0003] When handling peritoneal dialysis waste fluid, medical staff need to cut open the dialysis fluid packaging bag and pour out the waste fluid for separate treatment. Because the dialysis bag contains a large amount of waste fluid, it is easy for it to splash onto the medical staff at the moment of cutting, causing contamination or even infection. After the waste fluid has drained from the sewage tank, it needs to be treated a second time. The waste fluid bag and infusion tubing are cut a few more times and then retrieved for unified recycling. This reduces the safety and convenience of handling waste fluid bags. Utility Model Content

[0004] The purpose of this invention is to provide a peritoneal dialysis waste bag treatment device that improves the safety and ease of operation during waste bag treatment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A peritoneal dialysis waste bag treatment device includes a tank, a motor mounted at the bottom of the tank, a rotating shaft rotatably mounted inside the tank, an output shaft of the motor connected to the rotating shaft, blades mounted on the outer surface of the rotating shaft, a drain pipe mounted on the outer surface of the tank, and a valve installed inside the drain pipe. Two mounting slots are vertically formed on the outer surface of the rotating shaft, and cleaning brush plates are inserted into the mounting slots, with the bristle-covered side of the cleaning brush plates contacting the inner wall of the tank. A mounting mechanism is provided inside the rotating shaft to fix the cleaning brush plates in place. A tank cover is provided on the top of the tank.

[0007] Therefore, by placing the waste fluid bag into the tank and closing the lid, then starting the motor to rotate the shaft, the blades puncture the bag and cut the IV tubing as they rotate, and the waste fluid is discharged from the drain pipe. This quickly completes the treatment of the waste fluid bag, preventing it from splashing onto medical staff and causing contamination or even infection. Multiple waste fluid bags can be processed simultaneously. When the motor is started, it also drives the cleaning brush plate to clean the inner wall of the tank, eliminating the need for manual washing and preventing bacterial growth. This improves the safety and ease of operation during waste fluid bag treatment. The installation mechanism allows for quick and easy installation of the cleaning brush plate, making it even more convenient to use.

[0008] Furthermore, the installation mechanism includes an inner groove inside the rotating shaft, with a rod inserted inside the inner groove. A conical block is installed at the bottom of the rod, and a first spring is fitted onto the outer surface of the rod. The two ends of the first spring abut against the top wall of the inner groove and the conical block, respectively. Two positioning rods are provided inside the inner groove, and positioning grooves are formed on the outer surfaces of both cleaning brush plates. The positioning rods are inserted into the positioning grooves, and wedge-shaped blocks are installed on the outer surfaces of the positioning rods.

[0009] Since the cleaning brush plate is a consumable item, it needs to be replaced after a period of use. However, the blade design makes installation difficult and can easily cause hand injuries. Therefore, this device, through its installation mechanism, allows for quick and easy installation of the cleaning brush plate, avoiding hand injuries. In operation, first lift the insert rod upwards. The insert rod drives the conical block to compress the first spring. Then, insert the cleaning brush plate into the mounting slot. At this point, the positioning groove on the cleaning brush plate aligns with the positioning rod. Release the insert rod, and under the push of the first spring, the conical block presses against the wedge block, thereby driving the positioning rod to move and insert into the wedge block, achieving quick installation of the cleaning brush plate. Throughout the installation process, the hand does not come into contact with the blade and maintains a certain distance, thus preventing hand injuries.

[0010] Furthermore, two grooves are formed in the bottom wall of the inner groove. A sliding rod is installed inside the groove, and a slider is slidably installed on the outer surface of the sliding rod. The end of the slider is connected to the positioning rod. A second spring is sleeved on the outer surface of the sliding rod, and the two ends of the second spring abut against the inner wall of the groove and the slider, respectively.

[0011] When removing the cleaning brush plate, the insert rod can be lifted upwards. At this time, the conical block releases the squeezing force on the wedge block, and the positioning rod, under the pushing force of the second spring, can move away from the positioning groove and be pulled out from inside. At this time, the cleaning brush plate is no longer fixed, and it can be pulled out directly upwards.

[0012] Furthermore, a water injection pipe is installed on the upper surface of the can lid.

[0013] By installing a water injection pipe, cleaning fluid can be injected into the tank during internal cleaning, keeping the tank lid closed and avoiding the need to repeatedly open and close the lid to inject cleaning fluid, which would affect cleaning efficiency.

[0014] Furthermore, a handle is rotatably installed on the outer surface of the tank, and support feet are installed at the four corners of the bottom of the tank.

[0015] The handle makes the device easy to carry, and the feet provide space for the motor and improve the stability of the tank when it is placed.

[0016] Furthermore, a limit tube is installed on the lower surface of the can lid, and the limit tube is coaxially arranged with the rotating shaft.

[0017] When the lid is placed on the tank, the limiting tube is sleeved on the outside of the shaft end to limit its movement, thereby improving the stability of the shaft during rotation and preventing shaking. Attached Figure Description

DETAILED DESCRIPTION

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a peritoneal dialysis waste bag treatment device includes a tank 100. A motor 101 is installed at the bottom of the tank 100. A rotating shaft 102 is rotatably installed inside the tank 100. The output shaft of the motor 101 is connected to the rotating shaft 102. A blade 103 is provided on the outer surface of the rotating shaft 102. A drain pipe 104 is installed on the outer surface of the tank 100, and a valve 105 is provided inside the drain pipe 104. Two mounting slots 106 are formed vertically on the outer surface of the rotating shaft 102. A cleaning brush plate 107 is inserted into the mounting slots 106, and the side of the cleaning brush plate 107 with bristles contacts the inner wall of the tank 100. A mounting mechanism 200 is provided inside the rotating shaft 102 to fix the cleaning brush plate 107. A tank cover 108 is provided on the top of the tank 100.

[0025] In use, open the canister lid 108, place the waste fluid bag inside the canister body 100, then close the lid 108 and start the motor 101. The motor 101 drives the rotating shaft 102 to rotate, and the rotating shaft 102 drives the blade 103 to puncture the bag and cut the infusion tube. The waste fluid inside the bag is discharged from the drain pipe 104. Subsequently, the broken bag and infusion tube are removed from the canister body 100 and recycled for unified processing. This allows for the rapid disposal of waste fluid bags and prevents waste fluid from splashing onto medical personnel and causing contamination. This system can handle multiple waste bags simultaneously, even in cases of contamination or infection. When cleaning fluid is injected into the tank 100 and the motor 101 is started, the motor 101 drives the cleaning brush plate 107 to scrape the inner wall of the tank 100, achieving automatic cleaning without manual washing and preventing the growth of bacteria. This improves the safety and ease of operation when handling waste bags. The installation mechanism 200 allows for quick and easy installation of the cleaning brush plate 107, making it even more convenient to use.

[0026] Specifically, the installation mechanism 200 includes an inner groove 201 opened inside the rotating shaft 102, a rod 202 inserted inside the inner groove 201, a conical block 203 installed at the bottom of the rod 202, and a first spring 207 sleeved on the outer surface of the rod 202. The two ends of the first spring 207 abut against the top wall of the inner groove 201 and the conical block 203, respectively. The inner groove 201 contains two positioning rods 204. The outer surfaces of both cleaning brush plates 107 have positioning grooves 205. The positioning rods 204 are inserted into the positioning grooves 205. Wedge blocks 206 are installed on the outer surfaces of the positioning rods 204. Since the cleaning brush plates 107 are consumables, they need to be replaced after a period of use. However, the blades 103 make installation of the cleaning brush plates 107 difficult and prone to causing hand injuries. Therefore, this device, through the installation mechanism 200, allows for convenient and quick installation of the cleaning brush plates 107, avoiding hand injuries. Specific operation... During operation, the insertion rod 202 can be lifted upwards first. The insertion rod 202 drives the conical block 203 to compress the first spring 207. Then, the cleaning brush plate 107 is inserted into the mounting slot 106. At this time, the positioning slot 205 on the cleaning brush plate 107 is aligned with the positioning rod 204. The insertion rod 202 can be released. Under the push of the elastic force of the first spring 207, the conical block 203 squeezes the wedge block 206, which in turn drives the positioning rod 204 to move and insert into the wedge block 206, realizing the quick installation of the cleaning brush plate 107. During the entire installation process, the hand does not come into contact with the blade 103 and a certain distance is maintained, thereby avoiding hand injury.

[0027] Specifically, two grooves 300 are formed in the bottom wall of the inner groove 201. A slide rod 301 is installed inside the groove 300. A slider 302 is slidably installed on the outer surface of the slide rod 301, and the end of the slider 302 is connected to the positioning rod 204. A second spring 303 is sleeved on the outer surface of the slide rod 301. The two ends of the second spring 303 abut against the inner wall of the groove 300 and the slider 302, respectively. When the cleaning brush plate 107 is removed, the insertion rod 202 can be lifted upward. At this time, the conical block 203 cancels the squeezing force on the wedge block 206, and the positioning rod 204 can be driven to move away from the positioning groove 205 under the pushing force of the second spring 303 and be pulled out from inside. At this time, the cleaning brush plate 107 is no longer fixed and can be pulled out directly upward.

[0028] Specifically, a water injection pipe 400 is installed on the upper surface of the can lid 108. With the water injection pipe 400 installed, cleaning fluid can be injected into the can body 100 when cleaning the inside of the can body 100, keeping the can lid 108 in a closed state and avoiding the need to open the can lid 108 repeatedly to inject cleaning fluid, which would affect the cleaning efficiency.

[0029] Specifically, a handle 500 is rotatably mounted on the outer surface of the tank 100, and support feet 501 are installed at the four corners of the bottom of the tank 100. The handle 500 facilitates carrying the device, and the support feet 501 provide installation space for the motor 101 and improve the stability of the tank 100 when placed.

[0030] Specifically, a limiting tube 600 is installed on the lower surface of the can lid 108. The limiting tube 600 is coaxially arranged with the rotating shaft 102. When the can lid 108 is placed on the can body 100, the limiting tube 600 is sleeved on the outside of the end of the rotating shaft 102 to limit its movement, thereby improving the stability of the rotating shaft 102 during rotation and preventing shaking.

[0031] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
