Disposable precision measuring drainage bag is a commonly used medical device, mainly used for drainage and accurate measurement of human drainage fluid. Its functional characteristics are mainly reflected in the following aspects: 1. Correct measurement function Correct scale: The drainage bag is marked with clear scales, which can generally be accurate up to 1 milliliter or even smaller. It can accurately measure the volume of drainage fluid, making it easier for medical staff to accurately grasp the patient's drainage volume and providing important basis for disease diagnosis and treatment. There are various measurement methods: in addition to traditional scale measurement, some precision measurement drainage bags also use electronic measurement devices, which can measure and display the amount of drainage fluid in real time and correctly through sensors and other technologies. Some can also transmit data to electronic medical record systems, making it convenient for medical staff to view and analyze at any time. 2. Drainage function Smooth drainage: Drainage bags are usually equipped with drainage tubes of appropriate diameter, with smooth lumen and low resistance, which can ensure that drainage fluid flows smoothly into the drainage bag under gravity or negative pressure, avoiding blockage of the pipeline by drainage fluid and ensuring smooth drainage process. Anti backflow design: In order to prevent the drainage fluid from flowing back into the human body and causing adverse consequences such as infection, the drainage bag is equipped with anti backflow devices, such as one-way valves, so that the drainage fluid can only flow in one direction from the human body to the drainage bag, effectively ensuring the safety of patients. 3. Safety and hygiene functions Material safety: Medical grade polymer materials such as polyvinyl chloride (PVC), polyurethane, etc. are used, which have good biocompatibility, are non-toxic to the human body, and will not cause adverse effects such as allergic reactions, ensuring patient safety during use. Aseptic packaging: The product undergoes strict sterilization treatment during the production process, using aseptic packaging to maintain a sterile state before use. The packaging can be opened for use, reducing the risk of infection. Leak proof sealing: The interface and bag body of the drainage bag are designed with sealing, which has good leak proof performance, prevents drainage fluid leakage, avoids contaminating patients' clothing, bed sheets, and surrounding environment, and maintains the cleanliness and hygiene of the ward. 4. Convenient functions Easy to operate: The installation and use of drainage bags are simple, and medical staff or patient families can master them through simple training, making it easy to operate quickly and correctly in clinical practice and improving work efficiency. Convenient to carry: Small in size and light in weight, it will not cause too much burden for patients who need to carry drainage bags for activities. Patients can move freely within a certain range, which is conducive to improving their quality of life and recovery effect. Clear identification: Drainage bags are usually marked with important information such as product name, specifications, scale, production date, expiration date, etc. The identification is clear and eye-catching, which facilitates quick identification and use by medical staff, and also helps trace the quality and batch information of the product. 5. Other functions Observation function: Drainage bags are generally made of transparent or semi transparent materials. Medical staff can intuitively observe the color, characteristics, transparency, etc. of the drainage fluid, such as whether there is blood, pus, flocculent substances, etc., in order to timely detect changes in the patient's condition and provide reference for diagnosis and treatment adjustment. Capacity selection: According to the drainage needs of different patients, there are multiple capacity specifications to choose from, such as 500 milliliters, 1000 milliliters, 2000 milliliters, etc. Medical staff can choose the appropriate capacity drainage bag according to the actual situation of the patient, avoiding inconvenience caused by frequent replacement of drainage bags.
