Medical Anti-reflux Drainage Bag,Urine Collection Bags,Urinary Catheter-connected Urine Bags

Introduction

This series of products includes medical anti-reflux drainage bags, disposable urine collection bags, and drainage bags connected to urinary catheters, which are suitable for men, women, the elderly, and children. All of them are medical-grade products made of medical PVC material. The bags are thick and impermeable, equipped with anti-reflux and anti-leakage designs, and the anti-reflux devices are mostly in the form of diaphragms. They are individually packaged, which can effectively reduce the burden of nursing care and make life more convenient.

Medical Anti-reflux Drainage Bags: Primarily used for collecting and storing urine drained from the human body, such as urine drained through urinary catheters. Its core function is to prevent urine reflux, avoiding the backflow of urine into the human urinary system, thereby reducing the risk of urinary system infections. It plays a crucial role in clinical nursing and long-term urine drainage processes. This disposable urine collection bags used for temporary or short-term urine collection, facilitating patients’ use when they have limited mobility or need continuous monitoring of urination. The disposable design ensures hygiene. After use, they can be discarded directly, reducing the possibility of cross-infection. It is a convenient urine collection tool applicable to various scenarios like hospitals and home care. This urinary catheter-connected urine bags, as a supporting device for urinary catheters, it is closely connected to the urinary catheter and used for receiving and storing the urine drained by the urinary catheter. It can ensure that urine flows smoothly from the urinary catheter into the urine bag and usually also has a certain anti-reflux function, being an indispensable part of the catheterization system.

Material Composition

• Body Material: Generally, medical-grade plastic materials such as polyvinyl chloride (PVC) or polyethylene (PE) are used. These materials have good flexibility and toughness, can withstand a certain amount of urine weight and pressure, and are light enough to be convenient for patients to carry or hang. PVC material urine bags have relatively high transparency, facilitating the observation of the color, volume, etc. of urine; PE material is relatively softer and has a better tactile feel.
• Connection Part Material: The interfaces connected to the urinary catheters are usually made of medical plastics and are designed to fit closely with the urinary catheters to prevent urine leakage. Some products have anti-disengagement devices at the interfaces, such as elastic buckles or screw interfaces, ensuring that the urine bags are firmly connected to the urinary catheters during use.
• Hanging Device Material (if any): Some drainage bags are equipped with hanging devices, such as hooks or ropes, which are used to hang the urine bags beside the bed or on the patient’s body. These hanging devices are generally made of materials such as plastics or nylon and have sufficient strength to support the urine collection bags filled with urine.

Practical Capacity: There are two specifications of 1000ml and 1500ml. The large capacity of 1500ml reduces the frequency of drainage and emptying, relieving the pressure of nursing care.

Excellent Catheters: There are 1.2-meter thickened and anti-kinking drainage tubes or tubes with a diameter of 60mm and a length of 1.1m, with an overall length of 1.4m. They are transparent and anti-kinking, ensuring smooth urine drainage, and the length is convenient for hanging in different postures.

Humanized Design: The hanging design combined with hanging straps makes it easy to fix; the drainage valve can be operated with one hand, and the cross-shaped drainage valve and pagoda-shaped head design are convenient to use; the scale is clear, facilitating the observation of urine volume; the anti-reflux valve prevents liquid from flowing back.

Features

(I) Anti-reflux Function

• Medical Anti-reflux Drainage Bags: Adopt special valve or pipeline designs to achieve anti-reflux. For example, some drainage bags are equipped with one-way valves inside. Urine can only flow from the urinary catheter into the urine collection bag and cannot flow in the reverse direction. This design is based on the principle of fluid mechanics. Once urine enters the urine bag, the one-way valve will automatically close to prevent urine backflow, effectively protecting the health of the patient’s urinary system.
• Disposable Urine Collection Bags and Urinary Catheter-connected Urine Bags (some with anti-reflux function): Some products also have similar anti-reflux mechanisms. Some set anti-reflux valves at the inlets connected to the urinary catheters. The valves open when urine passes through and close when there is a tendency of reflux. Others use the special curved shapes or internal structures of the pipelines to make urine flow in only one direction, thus achieving the purpose of anti-reflux.

(II) Capacity Marking and Transparency

• Clear Capacity Marking: All three types of urine bags have obvious capacity scale markings, making it convenient for medical staff or patients to intuitively understand the amount of urine collected. The scales are usually in milliliters (ml), ranging from dozens of milliliters to several liters, which can meet the needs of different patients and different drainage scenarios.
• High Transparency: The high transparency of the bag body helps to observe the properties of urine. Medical staff can preliminarily judge the patient’s physical condition, such as whether there is hematuria, proteinuria, or urinary system infection, by observing the color of urine, whether there are precipitates or flocculent substances, etc.

(III) Disposable Use and Hygiene

• Disposable Use Design: The disposable design of urine collection bags and urinary catheter-connected urine bags is an important feature. They can be discarded directly after use, avoiding the cross-infection that may occur during the cleaning and disinfection processes. For medical anti-reflux drainage bags, although it may not be necessary to replace the entire drainage bag every time in some long-term drainage situations, they will also be replaced after a specified usage time or when a certain capacity is reached to ensure hygiene and safety.
• Sterile Packaging: The high-quality products are packaged in a sterile manner when leaving the factory to ensure that the inside of the urine bags is in a sterile state before use. This is especially important for patients with low immunity or in medical environments with high requirements for aseptic operations.
