What is the function of precision urine bags
source：m.dailydigestblog.com | Release time：2025-12-02
Precision urine bag is a medical urine collection device with precise measurement, special protection, and adaptability to complex clinical scenarios. Its core function is to achieve accurate monitoring of urine volume and quality based on urine collection, while ensuring patient safety and comfort. The specific functions are as follows:
1、 Accurate urine volume monitoring to assist in disease diagnosis
High precision measurement function
The precision urine bag is equipped with a high-precision measuring scale with clear markings (some models can achieve an accuracy of ± 5mL), and some products come with independent micro measuring chambers, which can accurately record hourly urine volume and 24-hour total urine volume. For critically ill patients (such as shock, acute kidney injury), postoperative patients, or pediatric patients, urine volume is a core indicator for evaluating kidney function, blood volume, and changes in the condition. Accurate measurement can help medical staff adjust treatment plans in a timely manner (such as fluid replacement and diuretic dosage), avoiding delayed diagnosis and treatment due to urine volume monitoring errors.
Real time urine volume tracking
Some intelligent precision urine bags can be connected to monitors to achieve real-time transmission of urine volume data and abnormal alarms (such as automatic reminders when urine volume is less than 0.5mL/(kg · h)), suitable for scenarios such as ICU and neonatal intensive care unit that require continuous monitoring of vital signs.
2、 Adapt to special patient groups to enhance safety during use
Pediatric specific protection
The pediatric precision urine bag adopts a small interface, soft and leak proof material, and the measuring scale is adapted to the range of children's urine volume (such as 0-500mL), which can avoid leakage and skin irritation caused by mismatched interfaces of ordinary urine bags, and accurately monitor the development of infant kidney function and the treatment effect of diseases.
Anti reflux and infection prevention and control
Built in anti reflux valves (such as single directional flow valves) can effectively prevent urine from flowing back to the bladder, reducing the risk of urinary tract infections; Some products also use sterile sealed interfaces and antibacterial coating materials, which are suitable for patients with long-term indwelling catheterization (such as spinal cord injury and uremia patients), reducing the probability of cross infection in the hospital.
Low chamber pressure design to protect bladder function
The drainage tube of precision urine bags has lower resistance and some have pressure buffering structures, which can reduce bladder pressure fluctuations during urine drainage and avoid bladder mucosal damage due to excessive bladder filling or negative pressure, especially suitable for patients with bladder dysfunction.
3、 Exclusive adaptation for special clinical scenarios
Portable protection for sports and outdoor scenarios
Some precision urine bags adopt a compact design and are equipped with concealed straps or fixing devices. Patients can carry them for mild activities (such as sitting up at the bedside or walking short distances) without affecting urine volume measurement, balancing clinical monitoring and patient activity needs.
Preliminary screening assistance for urine quality
Some products have transparent observation windows or detachable sampling ports at the front end of the collection bag. Medical staff can quickly observe the color and turbidity of urine (such as hematuria and pus urine) with the naked eye, or conveniently collect urine samples for testing without disconnecting the drainage tube, reducing the risk of infection.
4、 Improve patient comfort and nursing efficiency
Low allergenicity and leak proof design
The parts that come into contact with the skin are made of medical grade silicone or low sensitivity non-woven fabric to reduce the probability of skin allergies; The sealed interface and leak proof side wings can prevent urine leakage, reduce patient skin immersion and clothing contamination, and enhance long-term comfort.
Simplify nursing procedures
Some precision urine bags are equipped with disposable drainage valves, which can empty urine without opening the bag body. The drainage process can be measured synchronously, simplifying the operation process of nursing staff, reducing the rate of operational errors, and reducing the risk of infection caused by urine exposure.
