Application of TPU materials in medical blood transfusion devices

Ⅰ. Material properties

1.Excellent flexibility:

。TPU material has a high elastic modulus, which enables the blood transfusion set to effectively reduce stress concentration and reduce the risk of damage to the blood transfusion set during use.

。Good flexibility also provides patients with a more comfortable infusion experience.

2.Abrasion resistance:

。The surface hardness of the TPU material blood transfusion set is high and the friction coefficient is low, which reduces the friction resistance of the liquid in the blood transfusion set and reduces the energy consumption during the blood transfusion process.

3.Good biocompatibility:

。TPU material is non-irritating to human skin and tissue, which reduces the discomfort of patients during the blood transfusion process.

。TPU has very good biocompatibility and temperature compliance. At the body temperature, the pipeline becomes soft and does not hurt blood vessels and organs. Therefore, it is widely used in high-value-added infusion pipelines implanted in the human body, such as intravenous indwelling needle cannula, mid-length catheter (Midline), central venous catheter CVC/PICC, etc.

4.High temperature resistance:

。TPU material has good high temperature resistance, which enables the blood transfusion set to maintain stable performance in high temperature environments.

5.Light-proof performance:

。Some TPU light-proof blood transfusion sets are made of special TPU materials, which can effectively block ultraviolet and visible light exposure, thereby protecting the blood from photolysis and ensuring the stability and therapeutic effect of the blood.

Ⅱ. Application advantages

1.Safety:

。TPU materials are non-toxic and odorless, and will not affect the health of patients.

。Good biocompatibility reduces the risk of allergic reactions and infections during blood transfusion.

2.Comfort:

。Excellent flexibility allows the blood transfusion set to fit the patient's body curve more closely during use, reducing discomfort.

3.Durability:

。TPU material has high wear resistance and high temperature resistance, which extends the service life of the blood transfusion set.

Ⅲ. Precautions

1.Chemical resistance:

。TPU material has relatively poor chemical resistance and may be corroded by certain chemicals. Therefore, chemicals that may damage TPU materials should be avoided during blood transfusion.

2.Cost:

。The price of TPU material is relatively high, which may increase medical costs. However, considering its excellent performance and patient comfort, this cost is worth it.

Medical blood transfusion device TPU material has a series of unique advantages and application advantages, providing patients with a safer, more comfortable and efficient blood transfusion experience. However, during use, attention should also be paid to its chemical resistance and cost issues.
