Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a peritoneal dialysis waste liquid metering device for kidney patients. Background Art

[0002] Peritoneal dialysis (PD) is a renal replacement therapy that utilizes the peritoneum as a semipermeable membrane for dialysis. The basic principle is to use gravity to regularly and regularly infuse a prepared dialysate into the patient's peritoneal cavity via a catheter. The concentration gradient across the peritoneum is exploited to exchange solutes and water, thereby removing metabolic products and toxic substances from the body and correcting water and electrolyte imbalances.

[0003] Peritoneal dialysis offers advantages such as ease of operation, simple equipment, low cost, and safety. It can be performed at home, with flexible treatment times and no impact on patients' daily lives and work. It is suitable for patients with acute kidney injury and chronic renal failure, particularly those with severe cardiovascular disease, cerebrovascular disease, diabetes, and the elderly.

[0004] However, peritoneal dialysis also has some complications, such as peritonitis, metabolic complications, and lung infections. These complications are related to factors such as lax aseptic techniques, dialysate contamination, and low immunity. Therefore, when performing peritoneal dialysis, it is necessary to strictly adhere to operating procedures, pay attention to aseptic techniques, regularly monitor the patient's vital signs and dialysis results, and promptly detect and treat complications.

[0005] During the rehabilitation treatment of kidney patients, peritoneal dialysis treatment is mainly home treatment. Each patient will produce 3-5 bags of waste liquid during dialysis every day. Therefore, patients cannot avoid the tedious daily work of measuring and treating the waste liquid. At present, patients generally use a scale or a 3-5kg small scale to weigh the waste liquid bag first, and then use scissors to cut the bag or automatically dispose of the waste liquid. Such operations usually have the following shortcomings: 1. It is time-consuming and labor-intensive to cut the peritoneal dialysis waste liquid bags one by one with scissors, and the effect is poor; 2. The peritoneal dialysis waste liquid is manually dumped in an open environment, which is easy to splash and pollute the surrounding environment, increasing the risk of hospital infection; 3. The peritoneal dialysis waste liquid is not dumped completely, which increases the cost of medical waste disposal; 4. It is impossible to quickly measure the volume of the waste liquid and avoid splashing of the waste liquid when cutting the waste liquid bag.

[0006] Therefore, it is necessary to provide a peritoneal dialysis waste liquid metering device for kidney patients, which can quickly and effectively puncture the waste liquid bag, and quickly measure and harmlessly dump the waste liquid to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a peritoneal dialysis waste liquid metering device for kidney patients. The metering device is designed on the structure of quickly and effectively puncturing the waste liquid bag and collecting the waste liquid for metering. The spiked filter plate and the pressing plate cooperate to puncture the waste liquid bag and press out the waste liquid. After the waste liquid flows down, the volume can be directly read through the volume scale on the window.

[0019] The utility model provides a peritoneal dialysis waste liquid metering device for kidney patients. Compared with the traditional operation in which medical staff or patients at home manually cut the waste liquid belt, pour out the dialysis waste liquid and measure it, the utility model uses a mechanical structure to squeeze out the waste liquid in the form of puncture and pressing, avoiding the risk of direct contact with the waste liquid by personnel, and directly measures the waste liquid without the need for complex calculation processes.

[0020] Specifically, a hook on the outer wall of the box is equipped with pliers for clamping the waste liquid bag, which is then placed directly into the liquid flow chamber. By operating the operating lever, the pressing plate is pressed down, and the waste liquid bag is punctured by the spikes. The waste liquid then flows through the filter holes into the liquid accumulation chamber, and the volume of the waste liquid can be directly read through the window. During the process of puncturing the waste liquid bag and measuring the waste liquid, this device prevents the outflow and splashing of the waste liquid. The operator only needs to press and extract the waste liquid bag and clamp it to remove and place it in the waste liquid bag, simplifying the previous multiple measurement and manual cutting and draining operations. This avoids environmental pollution and achieves centralized discharge of waste liquid. BRIEF DESCRIPTION OF THE DRAWINGS
