Technical Field
[0001] This utility model relates to the field of drinking water appliance technology, and in particular to an automatic metering water dispensing cup lid and a large-capacity thermos cup. Background Technology
[0002] Kidney transplant patients often experience perioperative instability due to polyuria or oliguria caused by the transplanted kidney, requiring comprehensive and meticulous management across multiple aspects, including fluid intake and output, clinical findings, and laboratory tests. Urine output is a crucial indicator for assessing kidney function and guiding fluid replacement; therefore, continuous 24-hour monitoring of urine output is essential during the perioperative period. Nursing care should include detailed recording of hourly urine output changes postoperatively, and fluid management should be tailored to the individual patient's needs during the polyuric and oliguric phases. The polyuric phase begins after blood flow is restored to the transplanted kidney, with 24-hour urine output reaching 5000-10000 mL. Fluid replenishment is critical as patients transition from preoperative water and sodium retention to significant postoperative dehydration. Since the primary risk during the oliguric phase is fluid overload, fluid management should focus on restricting fluid intake and output, with output being measured to determine intake. Daily fluid intake should be calculated based on the patient's urine output and physiological needs.
[0003] Furthermore, with the increasing popularity of the concept of enhanced recovery after surgery (ERAS), encouraging patients to drink water and eat early after surgery and discontinue intravenous fluid replacement as soon as possible has a significant impact on patient prognosis. Kidney transplantation has minimal impact on the gastrointestinal tract; if there are no discomforts 6 hours after surgery, oral rehydration can begin. Patients should be encouraged to drink water to maintain a balance between fluid intake and output. This not only helps reduce complications and promotes patient recovery but also alleviates the economic burden and psychological stress on patients, while conserving medical resources. Good fluid control after surgery can promote the recovery of transplanted kidney function. Kidney transplant patients should drink more than 2000 mL of water per day. If oliguria occurs, the daily fluid intake should be 500-750 mL plus the total urine output of the first 24 hours.
[0004] Considering the limited mobility of many postoperative patients, and the fact that existing insulated water bottles typically have a capacity of 300-600mL, it is difficult to accurately measure the amount of water consumed each time. Multiple refills are often required to meet the daily recommended intake. Using a push-button dispenser is also quite difficult, and even a full, heavy, or straw-type insulated water bottle can be difficult for weak patients to hold securely. Furthermore, patients in the postoperative recovery period can only drink while lying down and cannot sit upright, requiring careful attention to the proper way of oral drinking. Therefore, a suitable, large-capacity, dispenser-type water bottle for patients is needed. This would not only ensure their daily hydration needs are met but also reduce the workload of medical staff, facilitate perioperative fluid management, promote rapid patient recovery, and lower medical costs.
