The application of medical films in the medical field meets the various needs of the medical industry. Surgical films play a key isolation role during surgery, preventing blood, body fluids and other contaminants from contacting objects or people outside the surgical area, thereby reducing the risk of cross infection. Transparent or translucent surgical films allow doctors to clearly see the surgical area during surgery, ensuring the accuracy and safety of the operation. According to the specific needs of the operation and the physical condition of the patient, surgical films of different materials, such as polyester film, polypropylene film, etc., can be selected to meet different biocompatibility, tensile strength and waterproof performance requirements.
During surgery, medical films can be used to separate and protect different tissues, prevent them from adhering to each other, and reduce postoperative complications. Some medical films also have the function of promoting tissue healing and reducing scar formation, such as films containing specific bioactive substances.
Medical films play a key role in the sterile packaging of medical devices and consumables. They can provide good barrier properties, prevent the invasion of microorganisms, and ensure the sterility of medical devices and consumables during storage and transportation. In addition to sterility, medical films can also protect medical devices and consumables from physical and chemical damage, such as scratches, corrosion and oxidation. Identification information, such as product name, specifications, production date, expiration date, etc., can also be printed on medical films, which is convenient for medical staff to check and trace before use.
Medical films mainly play the role of blocking oxygen, moisture and microorganisms in the packaging of drugs and biological agents, thereby extending the shelf life and stability of drugs. Transparent medical films allow medical staff to check the appearance and state of drugs without opening the package, ensuring the quality of drugs during storage and transportation. Some drug packaging also uses medical films with child-safe properties to prevent children from accidentally ingesting them.
Medical films are used in medical facilities to cover bed sheets, mattress covers, wall coverings and floor glue, etc., providing surfaces that are easy to clean and disinfect, helping to maintain the hospital's hygiene standards. Protective equipment such as surgical gowns, protective masks, and gloves are also often made of medical film materials, providing an effective protective barrier and reducing the risk of cross-infection between medical staff and patients. In order to avoid cross-infection and reduce the cost of medical waste disposal, many protective equipment made of medical films are designed for disposable use.
Medical films play a key role in the manufacture of artificial organs and implants, such as being components of heart valves, vascular stents and other devices, providing the necessary biocompatibility and mechanical properties. Some medical films have good air permeability and moisture permeability, and can be used to make wound dressings and bandages, which help wounds heal and prevent infection. These films can also contain bioactive ingredients such as antibacterial substances and growth factors to promote faster recovery of wounds. In medical diagnosis, medical films can be used to make various sensors and test strips to detect patients' physiological indicators and disease states. In terms of treatment, medical films can also be used to make drug delivery systems, such as patches, membranes, etc., to achieve timed and quantitative release of drugs.
