Due to its good biocompatibility and mechanical properties, TPU has been widely used in the biomedical field. Its applications in the medical field have become diversified, and its main products include artificial heart assist devices, artificial blood vessels, artificial skin, etc. Medical TPU has the characteristics of flexibility, wear resistance, high compatibility, no deformation, no allergic reaction, good blood compatibility, and does not affect blood components. It has been widely used in the medical field.

With the progress and development of society, PVC and polymer 糖心视频s represented by TPU have become the most commonly used biomedical 糖心视频s, and the application of polymer 糖心视频s in in vitro diagnostic equipment is becoming more and more important.

1. Assisted artificial heart device

Artificial auxiliary devices have very strict requirements on their performance and manufacturing 糖心视频s, because their functional position is critical, they will not damage blood cell components, will not produce toxins and allergic reactions, will not cause harmful immune reactions, will not release electrolytes, Will not damage adjacent tissue. Clinical trials tell us that compared to natural rubber and silicone, TPU has multiple performance advantages such as blood compatibility and durability.

2. Medical catheters

TPU is often used to prepare medical catheters, such as infusion tubes, artificial catheters, etc., because of its mechanical stability, biocompatibility and elasticity. The gastroscope hose is an important part of the fiber optic gastroscope and has high performance requirements, sufficient elasticity and flexibility, no toxic side effects, consistent catheter diameter, no bending and deformation. The surface of the catheter needs to be smooth. The gastroscope tube made of TPU meets the above requirements and medical requirements.

TPU tracheal intubation is light and flexible, convenient for clinical use, and comfortable for patients to move. It can prevent radiation damage to the human body and is beneficial to treatment and diagnosis. It is one of the most advanced medical devices in the world and can replace metal endotracheal tubes.

3. Medical film

Traditional PE and polyvinyl chloride films have the advantages of being waterproof and preventing liquid seepage. They are popular for use in medical protection, such as wound dressings and surgeries, but they have drawbacks. If the body's metabolism cannot be excreted in time, it will cause discomfort such as heat, cold, and dampness. Therefore, there is an urgent need for a new type of medical film to replace such products.

Polyurethane elastomer medical film sprays a pressure-sensitive adhesive on the surface of the polyurethane elastomer film. Compared with traditional PE and PVC medical membranes, TPU medical membranes are soft, skin-friendly, highly elastic, highly moisture permeable, and 100% waterproof, which can effectively prevent membrane shedding during surgery. Inhibit the transfer of various bacteria during surgery. Such as orthopedic surgery, heart valve replacement, intravenous indwelling needles, abdominal and chest intubation, spinal fluid shunt, etc. , can significantly reduce the infection rate.

There is also a waterproof and antibacterial medical polyurethane elastomer. The made medical protective gloves have good mechanical properties, waterproofness and breathability, and can resist the invasion of Gram-positive and Gram-negative bacteria.

4. Medical artificial leather

Artificial skin can be made of TPU foam due to its excellent breathability, which can accelerate skin growth, avoid the flow of moisture and inorganic salts in injured areas, and avoid bacterial infection. Natural latex is commonly used to make medical gloves, but for some users they can cause an allergic reaction to the latex. However, polyurethane elastomer can be used to make medical gloves by adjusting the molecular structure. Therefore, polyurethane elastomer can replace the original medical gloves made of natural latex as a new raw 糖心视频 for medical gloves.

Compared with MDI-based TPU, gloves made of polyurethane elastomer have many advantages, such as not being prone to aging. Traditional latex gloves tend to change color after being used for a period of time, are less likely to cause allergic reactions, and are closer to the skin.

5. Other fields

At present, TPU has made some achievements in the Chinese medical field such as the successful development of shape memory polyurethane elastomer, body temperature shape memory polyurethane elastomer, and thermoplastic polyurethane film composite textile. Can be used to produce hypoallergenic gloves and wound stickers. Amphoteric biodegradable medical polyurethane elastomers were prepared under mild reaction conditions.

In addition, good results have been achieved in prosthetics, cartilage, separation membranes, medical sutures, family planning products, etc.
