5.1 Integration and Application of Advanced Materials

The white urine PVC film is not limited to a single PVC material but actively explores the integration and application of a variety of advanced materials to achieve comprehensive improvement in performance.

While considering increasing the strength and toughness of the film, high-molecular-weight polymer materials are added. Like a fine network, these polymer molecules intertwine among the PVC molecules, forming a powerful supporting structure, which allows the film to resist greater impacts from outer forces without breaking easily. Such special cases include impacts with heavy forces caused by great sport actions and accidental falls in medical operations, for example. A certain effect can be attained using a white color urine PVC film that would resist these high impacts owing to high-molecular polymers that constitute the white PVC. As a result, damage will not spread beyond a point and no urine leak would be obtained that will secondarily traumatize the patient.

Anti-odor materials are added specifically to solve the problem of urine odor highly effectively. These anti-odor materials can capture various odor molecules emitted from urine through physical adsorption or chemical reaction and neutralize them to keep the air around the urine bag fresh and pleasant. This will be of great significance to improve the patient's comfort level and the air quality of the medical environment, especially in places with concentrated people and relatively limited ventilation conditions, such as hospital wards and nursing homes. The urine bags with good anti-odor performance are in high demand.

In terms of antibacterial and anti-infection, the white urine PVC film contains antibacterial agent components. These antibacterial agents can continuously release ions or active substances with bactericidal effects, effectively inhibiting and killing common bacteria, fungi and other microorganisms in urine. In this way, the risk of patients developing urinary system infections or other related infections due to the use of urine bags can be greatly reduced, providing an additional protective barrier for the patient's health. In the nursing process for long-term bedridden patients or patients of low immunity, the use of urine bags with antibacterial properties is crucial. It could reduce the rate of nosocomial infection to some degree and alleviate suffering and medical burden on the patients.

5.2 Exquisite Structural Design

1.Independent Double-Layer Structure - Double Protection, Absolute Security

The white urine PVC film, with the independent double-layer structure it has adopted, is a perfect combination model for engineering design and medical needs. The inner layer, directly in contact with urine, is a special formula material with high resistance to corrosion and leakage. Its main responsibility is to ensure that urine is safely stored and any leakage of urine is prevented. This layer of film is like a loyal guard, standing on the front line of contact with urine, silently withstanding the erosion and pressure of urine.

The outer layer of the film plays the role of protector and supporter. It provides additional physical protection for the inner layer inside the film, preventing it from being damaged when external forces are applied in the form of squeezing, friction, or collision. Meanwhile, its outer layer has good abrasion resistance and puncture resistance, which can effectively resist all kinds of risk factors that may exist in the outside environment, such as scratches by sharp tools or abrasive surfaces. This independent double-layer structure can be said to have strongly armored the urine bag. Be it the slightest collision in everyday use or some accidental squeeze in transportation and storage, the urine bag could easily overcome it to give double security for the safe storage and transportation of urine and make medical staff and patients feel confident enough in using it.

2. Easy-open-and-close Structure for Ease in Operation and Unlimited Convenience

During use of the urine bag, there is a need for frequent emptying and replacement operations, which require a simple and convenient opening and closing mechanism. The easy-open-and-close structure designed for the white urine PVC film perfectly solves this problem.

In the discharge port of the urine bag, an up-to-date valve design is adopted. This structure of the valve cleverly uses the principles of mechanics, which can achieve quick and smooth opening and closing with just a light rotation or press. When it is necessary to empty the urine bag, the patient or medical staff can easily operate the valve to allow the urine to flow out quickly and completely, avoiding the problem of urine residue caused by valve blockage or inconvenient operation. When closing, it only needs a little, but the valve can closely close and form a reliable sealing effect and no urine leakage. This open/close structure is not only straightforward to operate but also offers super-high reliability and strength that can withstand use with high repetition. After multi-repeated use, the performances are still good enough, which provides a high guarantee for the long term in using the urine sack.

3. Anti-Splash Structure - Thoughtful Protection, Clean and Worry-Free

Urine is easily subjected to splashing during the flowing process, which pollutes not only the surrounding environment but may also bring hygienic hazards to patients and medical staff. To solve this problem, a special anti-splash structure is designed inside the urine bag made of white urine PVC film.

Such an anti-splash structure usually adopts special diversion grooves and buffer devices. The diversion grooves can divert the urine to flow along a predetermined path at a low speed while the urine flows into the urine bag, thereby avoiding the direct impact of urine on the wall and causing splashes. At the same time, the buffer device will effectively absorb the impact force of the urine and convert it into mild kinetic energy, further reducing the possibility of urine splashing. Near the outlet of the urine bag, an anti-splash baffle is also set. When the urine bag is tilted or shaken, the anti-splash baffle can block the spillage of urine and keep it safely in the bag. This thoughtful anti-splash structure design fully reflects the care and respect for patients and medical staff and makes a positive contribution to creating a clean and hygienic medical environment.

They needn't get up frequently to go to the toilet. They can use the urine bag beside the bed to solve the problem of urination. Moreover, with the good performances in leakage prevention and wear comfort, patients can use the urine bag without any worry that urine leakage will cause them a lot of inconveniences or embarrassment in some situations.

In addition, postoperative patients require close observation of the urination situation during physical recuperation and have high hygienic and safety demands on the urine bag. The white urine PVC film can be made into a urine bag to meet the needs of these aspects. The transparent body of the bag is convenient for medical staff to observe the color, amount, and other information of the urine at any time, so as to find abnormal situations in time and take corresponding treatment measures. And the antibacterial, anti-odor, and other properties can effectively avoid infections, creating a good condition for the patient's recovery.

During pregnancy, especially in the late stage of pregnancy, pregnant women often have frequent urination due to the pressure from the fetus. At this time, a convenient and comfortable urine bag is particularly important. The white color urine PVC film-made urine bag is light and portable, and can be easily put into a pregnant woman's handbag or pocket to meet their needs anytime and anywhere. Moreover, the soft material and design that fit the human body curve will not cause any discomfort to the pregnant woman's body, making them spend the pregnancy more easily and comfortably.

Moreover, this white urine PVC film is used to make a urine bag, which can also be an ideal choice for patients with urinary system diseases or those who require long-term urine monitoring. The accurate scale markings and good visibility are helpful for patients and medical staff to accurately record the amount of urine discharged, which provides an important basis for the diagnosis and treatment of diseases.

6. Technological Development Outlook: Leading the New Trend of Future Medical Supplies

6.1 In-depth Exploration and Application of Environmental Protection Materials

With the increasingly severe global environmental problems, the concept of environmental protection has been deeply rooted in people's hearts, and the medical supplies industry is no exception.
