Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a bag for peritoneal dialysis fluid. Background Technology

[0002] Peritoneal dialysis bags are essential medical devices used in peritoneal dialysis treatment to help patients with chronic renal failure remove metabolic waste and excess water from their bodies. The peritoneum acts as a natural filter during peritoneal dialysis, injecting dialysate into the peritoneal cavity and utilizing the exchange of substances between the peritoneum and blood to remove uremic toxins and balance electrolytes and fluids. In current peritoneal dialysis bag treatment, patients need to periodically inject dialysate into the peritoneal cavity through a short tubing connected to the catheter, allowing it to remain for a period before being drained again. Therefore, the protection of this short tubing is crucial. However, current peritoneal dialysis bags do not provide sufficient protection for the short tubing. When patients shower or come into contact with humid environments, moisture can easily enter the peritoneal dialysis catheter connected to the peritoneal cavity through the short tubing, increasing the risk of infection. The short tubing is a critical component connecting the dialysis bag and the peritoneal dialysis catheter during peritoneal dialysis. Once moisture enters the short tubing, bacteria and other microorganisms may enter the peritoneal cavity, causing peritonitis. Peritonitis is one of the most common complications in peritoneal dialysis patients, not only interrupting dialysis treatment but also damaging peritoneal function. Waterproof stickers and covers commonly available on the market can temporarily protect short tubes from water and moisture, but they are prone to loosening or falling off after prolonged use and may cause skin allergies or irritation. Antibacterial ointments or gauze, on the other hand, cannot block moisture.

[0003] Therefore, there is an urgent need for a peritoneal dialysis fluid bag to solve the problems existing in the current technology. Utility Model Content

[0029] Referring to Figures 1-2 The present embodiment provides a peritoneal dialysis solution bag, which comprises a storage unit 1 comprising a dialysis bag 110;

[0030] The short tube 2 is provided with a groove 210 and a protrusion 220, and the short tube 2 is integrally provided with a protrusion 220 on the upper and lower sides, respectively, and the short tube 2 is provided with a groove 210 on the left and right sides, respectively;

[0031] The flow guide unit 3 comprises a first flow guide pipe 310 and a second flow guide pipe 320, the first flow guide pipe 310 is fixedly connected to the dialysis bag 110, and the second flow guide pipe 320 is fixedly connected to the short tube 2 at one end;

[0032] The fastening and sealing unit 4 includes a fastening part 410 and a sealing part 420. The fastening part 410 is arranged at one end of the second flow guide pipe 320, and the short pipe 2 is arranged in the fastening part 410. The sealing part 420 is rotationally connected to the fastening part 410.

[0033] Specifically, peritoneal dialysis is a method for treating chronic renal failure, which uses the peritoneum of the human body as a filter to remove metabolic waste and excess water in the body. When exchanging, the dialysis bag 110 needs to be hung at a high position, and the first flow guide pipe 310 on the dialysis bag 110 is connected to the short pipe 2 on the second flow guide pipe 320 for exchange operation. The other end of the second flow guide pipe 320 is in the abdominal cavity of the human body. After the dialysis fluid is injected into the abdominal cavity of the patient, it will stay in the abdominal cavity for a period of time. Through the material exchange between the peritoneum and the blood, the waste and excess water in the body are removed. At the same time, the temperature and color of the dialysis fluid in the abdominal cavity are monitored, and the time and amount of dialysis fluid in and out are recorded, so as to evaluate the treatment effect of the doctor. The second flow guide pipe 320 serves as a channel connecting the abdominal cavity and the outside world. The short pipe 2 arranged thereon is coated with an iodophor layer to form a sterile environment. However, when it is humid or the patient takes a bath, water can easily flow into the second flow guide pipe 320 through the gap of the short pipe 2, and then into the human body, thereby increasing the risk of infection. The fastening and sealing unit 4 wraps the short pipe 2, and through the sealing part 420 and the fastening part 410, a sealed space is formed inside the fastening part 410, thereby protecting the short pipe 2 in the sealed space from the influence of the external environment and maintaining its dry state.

[0034] It can be understood that by arranging the fastening part 410 at one end of the second flow guide pipe 320, the short pipe 2 is completely wrapped therein to form a sealed space, which isolates the moisture and humidity in the external environment. The sealing design not only prevents water from flowing into the second flow guide pipe 320 through the gap of the short pipe 2 when the patient takes a bath or contacts a humid environment, thereby entering the abdominal cavity, but also reduces the risk of infection caused by the entry of water, especially the risk of peritonitis, which is a common complication in peritoneal dialysis. Peritonitis not only interrupts treatment, but also can cause serious physiological problems, increase hospitalization rate and treatment cost. The fastening and sealing unit 4 improves the safety of treatment and ensures the sterile state of the peritoneal dialysis environment.

[0035] Secondly, when the patient needs to perform dialysate exchange, he or she only needs to open the sealing part 420 and connect the first flow guide pipe 310 to perform the operation, and close the sealing part 420 after use. The simple operation process reduces the burden of the patient and reduces the complexity of daily care. Especially for the elderly or patients with difficulty in movement, simplifying the operation steps can improve their self-care ability and reduce their dependence on nursing staff. In addition, the patient can be more at ease when taking a bath or performing other daily activities without worrying about the protection of the dialysis pipeline, further reducing psychological pressure and worry. The traditional waterproof stickers or waterproof sleeves may cause skin allergy, irritation or ulceration after long-term use, increasing the risk of infection. The fastening sealing unit 4 does not contact the human skin, reducing direct contact and friction with the patient's skin, and reducing the possibility of skin allergy and irritation. Patients often need to perform dialysate exchange several times in daily life, and traditional protection measures need to be frequently replaced and adjusted, increasing the time and energy burden of the patient. The use of the fastening sealing unit 4 allows the patient to no longer need to use waterproof stickers or waterproof sleeves before and after each dialysate exchange, saving time and resources.

[0036] In some embodiments of the present application, referring to Figure 3 As shown, the fastening part 410 includes a fastening sleeve 4101, a connecting strip 4102, a sealing groove 4103 and a limiting groove 4104, the sealing groove 4103 is opened on the inner wall of the fastening sleeve 4101 away from one end of the second flow guide pipe 320, the limiting grooves 4104 are opened on the left and right sides of the middle part of the inner wall of the fastening sleeve 4101, and the limiting grooves 4104 correspond to the positions of the grooves 210, and the connecting strip 4102 is rotationally connected to one side of the outer surface of the fastening sleeve 4101.

[0037] In some embodiments of the present application, the fastening part 410 further includes a limiting plate 4105 and a limiting spring 4106, the limiting plates 4105 corresponding to the positions of the protrusions 220 are fixedly connected to the upper and lower sides of the inner wall of the fastening sleeve 4101, and the limiting spring 4106 is fixedly connected in the limiting groove 4104.

[0038] Specifically, one end of the fastening sleeve 4101 is connected to the second flow guide pipe 320, and the short pipe 2 is placed in the space inside the fastening sleeve 4101, and the limiting groove 4104, the limiting plate 4105 and the limiting spring 4106 on the inner wall of the fastening sleeve 4101 are used to fix the short pipe 2 to prevent it from moving in the space inside the fastening sleeve 4101, especially when the patient moves, the short pipe 2 will shake in the internal space, thereby increasing the risk of falling or leaking, when the short pipe 2 is located inside the fastening sleeve 4101, the protrusions 220 on the upper and lower sides correspond to the limiting plate 4105, and the recesses 210 on the left and right sides are fastened by the limiting spring in the fastening part 410, and the connecting strip 4102 is rotationally connected to the outer surface of the fastening part 410, and the other end is connected to the sealing part 420, when it is necessary to seal the space inside the fastening sleeve 4101, cover the sealing part 420, when it is necessary to exchange dialysis liquid, the sealing part 420 can be opened by the connecting strip 4102, thereby operating the short pipe 2.

[0039] It can be understood that the fastening part 410 ensures the stable fixation of the short tube 2 inside the fastening sleeve 4101. The limiting plate 4105 fixedly connected on the inner wall of the fastening sleeve 4101 corresponds to the protrusion 220 of the short tube 2, preventing the displacement of the short tube 2 inside the space of the fastening sleeve 4101. The limiting spring 4106 in the limiting groove 4104 further fastens the left and right grooves 210 of the short tube 2 through its elastic action, ensuring that the short tube 2 is fixed firmly in all directions. Through multiple fixations, the shaking of the short tube 2 can be reduced when the patient moves or carries out daily activities, reducing the risk of the short tube 2 falling or the second drainage tube 320 leaking. The stable fixation of the fastening part 410 not only improves the safety of the dialysis process, but also reduces the risk of infection caused by loose connection or leakage, especially peritonitis. Peritonitis is a common complication in peritoneal dialysis, which not only interrupts treatment, but also can cause serious physiological problems, increasing hospitalization rate and treatment cost. The fastening and sealing unit 4 improves the safety of treatment and ensures the sterile state of the peritoneal dialysis environment, providing patients with a more reliable dialysis experience. The dialysis fluid exchange operation is more convenient with the fastening part 410. When the patient needs to perform dialysis fluid exchange, he / she only needs to open the sealing part 420, connect the first drainage tube 310, and then perform the operation. After use, the sealing part 420 is closed. This simple operation process reduces the burden on patients and reduces the complexity of daily care. Especially for the elderly or patients with limited mobility, simplifying the operation steps can improve their self-care ability. Traditional dialysis tube connection methods are prone to leakage or loosening during use, especially after multiple operations, the sealing performance of the connection part will gradually decrease. The fastening and sealing unit 4 ensures the stable and reliable connection between the short tube 2 and the second drainage tube 320 through the double protection of the fastening part 410 and the sealing part 420, reducing the risk of dialysis fluid leakage. Not only ensures the effect of dialysis treatment, but also reduces the risk of pollution and infection caused by dialysis fluid leakage, providing patients with a safer and more effective treatment environment. The design of the limiting groove 4104 and the limiting spring 4106 further enhances the fixing effect of the short tube 2, ensuring that the dialysis fluid will not leak or the connection will not loosen due to the displacement of the short tube 2 during injection and discharge. The fastening part 410 reduces the cost of care. Traditional dialysis equipment needs to frequently replace and adjust waterproof stickers or waterproof sleeves during use, increasing the cost of care and the economic burden on patients. The use of the fastening and sealing unit 4 reduces the use of additional care tools and materials, reducing the cost of care. The structural design of the fastening part 410 enables it to maintain good sealing performance and fixing effect after multiple uses, prolonging the service life of the equipment and reducing the frequency of replacement and maintenance.

[0040] In some embodiments of the present application, reference is made to Figure 4As shown, the sealing part 420 includes a sealing sheet 4201, a first sealing sleeve 4202, the sealing sheet 4201 is fixedly connected to the connecting strip 4102, the first sealing sleeve 4202 is fixedly connected to the sealing sheet 4201, and the first sealing sleeve 4202 is sealingly connected to the sealing groove 4103.

[0041] In some embodiments of the present application, the sealing part 420 further includes a second sealing sleeve 4203 and a blocking sheet 4204, the second sealing sleeve 4203 is sleeved on one end of the second flow guide pipe 320, and one end of the second sealing sleeve 4203 is located in the fastening sleeve 4101, and the blocking sheet 4204 is arranged on the sealing sheet 4201.

[0042] Specifically, the sealing sheet 4201 is provided with the blocking sheet 4204 and the first sealing sleeve 4202, the sealing sheet 4201 is rotatably connected to the fastening sleeve 4101 through the connecting strip 4102, and the opening or sealing effect is realized, when the sealing sheet 4201 is covered, the first sealing sleeve 4202 thereon forms a sealing structure with the sealing groove 4103 on the fastening sleeve 4101, at the same time, the blocking sheet 4204 fixes the sealing sheet 4201, preventing it from rotating and affecting the sealing effect, the second sealing sleeve 4203 is arranged at the connecting position of the second flow guide pipe 320 and the fastening sleeve 4101, preventing water from entering the internal space of the fastening sleeve 4101 from the gap at the connecting position of the second flow guide pipe 320 and the fastening sleeve 4101.

[0043] It can be understood that the sealing part 420 improves the sealing performance of the dialysis pipeline through the multi-layer sealing structure. The first sealing sleeve 4202 and the sealing groove 4103 on the fastening sleeve 4101 form a sealing structure, ensuring the tightness of the connection part and preventing external moisture from entering. The second sealing sleeve 4203 is sleeved on one end of the second flow guide pipe 320, further enhancing the sealing effect of the connection part and preventing moisture from entering the internal space of the fastening sleeve 4101 from the gap. Not only does it improve the reliability of dialysate exchange, but it also reduces the risk of infection caused by leakage or moisture entering. Traditional waterproof stickers or waterproof sleeves may fail in humid environments, allowing moisture to enter the dialysis pipeline and increasing the risk of infection. The sealing part 420 of the fastening sealing unit 4 is protected by the double-layer protection of the first sealing sleeve 4202 and the second sealing sleeve 4203, as well as the auxiliary fixation of the sealing groove 4103 and the stopper 4204, ensuring the sealing performance of the device in various environments. The sealing part 420 reduces the frequency of care and maintenance costs. Traditional waterproof stickers or waterproof sleeves need to be replaced frequently, especially for patients who undergo dialysate exchange multiple times a day. This frequent replacement increases the complexity and frequency of care. The sealing part 420 of the fastening sealing unit 4 reduces the frequency of replacement and maintenance. The sealing sheet 4201 and the first sealing sleeve 4202 ensure that the device can maintain good sealing effect after long-term use. This reduces the economic burden on patients and the work intensity of medical staff, improving the economy and efficiency of treatment. The stopper 4204 on the sealing sheet 4201 provides additional protection while fixing the sealing sheet 4201, preventing external forces from affecting it. This not only improves the safety and reliability of the device, but also reduces the additional protective tools that patients need to use, simplifies the operation process, and improves the patient's use experience. The sealing part 420 is easy to clean and disinfect, improving the hygiene performance of the device. Patients can easily clean and disinfect before and after each dialysate exchange, ensuring the hygiene of the dialysis pipeline. The structure design of the second sealing sleeve 4203 also makes it more convenient during cleaning and disinfection, reducing the possibility of cleaning dead angles and bacterial growth, not only reducing the risk of infection, but also improving the service life and reliability of the device.

[0044] In some embodiments of the present application, a waste bag 120 and a third flow guide pipe 330 are also included, and the third flow guide pipe 330 is fixedly connected to the waste bag 120.

[0045] In some embodiments of the present application, a Y-shaped tube 5 is also included, and the Y-shaped tube 5 is used to connect the first flow guide pipe 310, the second flow guide pipe 320, and the third flow guide pipe 330.

[0046] Specifically, when the patient needs to exchange the dialysis fluid, the waste bag 120 needs to be placed in a low position, usually a flat surface below the patient's abdomen, such as the ground or under a table. This can take advantage of gravity to help the waste liquid flow smoothly, and then connect the other end of the Y-shaped tube 5 to the second flow guide tube 320. Specifically, connect to the short tube 2 connected to the second flow guide tube 320, the patient needs to align and plug the interface of the Y-shaped tube 5, and then connect the other end of the Y-shaped tube 5 (the end not connected to the second flow guide tube 320) to the dialysis fluid bag flow guide tube, and perform the exchange operation.

[0047] It can be understood that placing the waste bag 120 in a low position, usually a flat surface below the patient's abdomen, such as the ground or under a table, takes advantage of the effect of gravity. Not only can the waste liquid flow more smoothly, but also reduces the difficulty and time of operation for the patient and medical staff.

[0048] The traditional method requires the patient to adopt a specific posture or use external equipment to help the waste liquid flow out, which not only complicates the operation, but also may cause incomplete or slow waste liquid discharge. By placing the waste bag 120 in a low position, the waste liquid can naturally flow from the patient's abdominal cavity into the waste bag 120 through the action of gravity, reducing the patient's waiting time and discomfort during the operation. The Y-shaped tube 5 is used to connect the first flow guide tube 310, the second flow guide tube 320 and the third flow guide tube 330, simplifying the connection steps. Traditional dialysis fluid exchange may require multiple disconnections and connections of different flow guide tubes, increasing the time and complexity of the operation. The Y-shaped tube 5 only needs to be connected to all flow guide tubes at one time, reducing the frequency and steps of the operation, and improving the convenience and efficiency of the operation. The patient needs to align and plug the interface of the Y-shaped tube 5, and this plug-in design makes the connection site more secure, reducing the risk of leakage due to improper connection. Especially during the waste liquid discharge process, the multi-point connection design of the Y-shaped tube 5 can better distribute the liquid pressure, ensuring that the waste liquid can flow smoothly from the abdominal cavity, reducing the problem of blockage or leakage caused by uneven pressure.

[0049] In some embodiments of the present application, the short tube 2 also includes an iodophor cap 6, and the short tube 2 is provided with a thread at one end, and the iodophor cap 6 is threadedly connected to the short tube 2.

[0050] It can be understood that the iodophor cap 6 improves the sterility and safety of the equipment. The iodophor cap 6 contains iodophor disinfectant inside, which can prevent bacteria and other microorganisms from invading the dialysis pipeline from the outside. Before the patient uses the equipment each time, only the iodophor cap 6 needs to be unscrewed, and a short disinfection operation is performed to ensure the aseptic state of the connection part of the short tube 2 and the second flow guide pipe 320. Not only simplifies the disinfection steps, but also reduces the risk of infection and improves the safety of treatment. The short tube 2 is provided with a thread at one end, and the iodophor cap 6 is connected to the short tube 2 through the thread, which ensures the sealing of the connection part and ensures that there is no gap between the short tube 2 and the iodophor cap 6. Prevent the entry of external air and contaminants. Not only improve the sterility of the equipment, but also reduce the leakage problem that may occur during operation, further improve the safety and reliability of the equipment.

[0051] In some embodiments of the present application, the dialysis bag 110 is also provided with a medicine adding port 7 on one side.

[0052] It can be understood that the traditional dialysate adding medicine needs to open the entire dialysis bag 110 flow guide pipe interface, which not only complicates the operation, but also easily causes contamination and leakage of the dialysate. The medicine adding port 7 allows the patient or medical staff to directly add the required medicine by only opening the medicine adding port 7, without the need to disassemble the entire flow guide pipe interface, which not only saves operation time, but also improves the simplicity and safety of the operation. The traditional medicine adding method needs to open the entire flow guide pipe interface, which increases the opportunity for dialysate to contact the external environment and easily causes bacterial and other microbial invasion. Through an independent medicine adding channel, the possibility of contamination is reduced, and the safety of dialysis treatment is improved. The patient or medical staff can directly add the required medicine dose through the medicine adding port 7 without the need to mix the medicine with the dialysate and then pour it into the dialysis bag 110. Ensure the accuracy and consistency of the medicine dose, and avoid the problem of insufficient or excessive medicine dose due to errors in the mixing process.

[0053] In some embodiments of the present application, the inner wall of the fastening sleeve 4101 is coated with a bactericidal layer.

[0054] It can be understood that the sterilization layer coated in the fastening sleeve 4101 ensures the persistent sterilization effect of the device during use. The sterilization layer in the fastening sleeve 4101 can prevent bacteria from breeding on the surface of the device. After long-term use of the dialysis pipeline, bacteria will accumulate at the connection site, increasing the risk of infection. The sterilization layer in the fastening sleeve 4101 inhibits the growth and reproduction of bacteria, reducing the accumulation of bacteria. Not only does it improve the sterility of the device, but it also extends the service life of the device and reduces device failures and treatment problems caused by bacterial breeding. When the patient needs to replace the fastening sleeve 4101 or the sterilization layer, they only need to open the sealing piece 4201 for replacement without disassembling other parts, reducing the complexity and time of maintenance. The patient or medical staff can clean the inside of the fastening sleeve 4101 with clean water or disinfectant after each dialysis fluid exchange by opening the sealing piece 4201, ensuring that the device is clean and sterile for the next use. Not only does it improve the hygiene performance of the device, but it also reduces the burden on the patient in daily care. When the patient opens the sealing piece 4201, the sterilization layer will contact the connection site of the flow guide tube, forming a protective film to prevent the invasion of bacteria and other microorganisms. This ensures the sterile state of the connection site before each operation, reducing the risk of infection caused by bacterial invasion. Traditional dialysis equipment may cause cross-infection due to frequent replacement and adjustment during use, but the sterilization layer in the fastening sleeve 4101 allows it to be cleaned and disinfected after each use, reducing the risk of cross-infection. The fastening sleeve 4101 is connected to the short tube 2 and the third flow guide tube 330 through threads, ensuring the sealing of the connection site. The sterilization layer forms a protective film on the inner surface of the connection site, preventing the entry of external dust, moisture, and other contaminants. Not only does it improve the sterility of the device, but it also reduces device failures and treatment problems caused by the entry of contaminants.

[0055] One of the above embodiments of the peritoneal dialysis bag protects the short tube by wrapping it with a fastening and sealing unit, creating a sealed space inside the fastening and sealing unit, and thus protecting the short tube from moisture and maintaining its dry state. When dialysis fluid needs to be exchanged through the dialysis bag, the sealing part is opened, and the short tube inside the fastening part is connected through the first flow guide tube for exchange. This not only reduces the risk of infection such as peritonitis caused by moisture entering the short tube, improves the safety of treatment, but also simplifies the daily care process for patients, eliminating the need for additional waterproof stickers or waterproof sleeves and other auxiliary tools when bathing or in a humid environment, reducing operational complexity and potential skin allergy problems. In addition, the fastening and sealing unit makes the dialysis fluid exchange process more convenient and reliable, and the patient only needs to open the sealing part to connect the short tube inside the fastening part through the first flow guide tube for dialysis fluid exchange, improving the convenience of treatment and the comfort of patients.

[0056] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
