How is the airbag of the biopressure feedback instrument produced by heat sealing

1. Material selection of airbag

The main material of the airbag of the biopressure feedback instrument is polyurethane elastomer. Polyurethane elastomer has excellent wear resistance, tear resistance, aging resistance and resilience, which can meet the various needs of the airbag during use. In addition, in order to ensure that the airbag has good biocompatibility, a certain amount of softener and catalyst is usually added to reduce the hardness and brittleness of the airbag.

2. Production process of airbag

1. High-frequency hot pressing: Put the TPU sheet of the airbag into the hot press for hot pressing. The specific hot pressing process includes steps such as heating, pressing and cooling. During the hot pressing process, the temperature of the hot press should be kept stable to ensure the sealing performance and strength of the airbag. In addition, attention should be paid to controlling the hot pressing time and pressure to avoid overheating or damage to the airbag.

2. Inspection and screening: The hot pressed airbag is subjected to appearance inspection and performance testing, such as dimensional accuracy, hardness, resilience, etc. For unqualified products, they should be screened and processed in time to ensure product quality.

3. Application fields of airbags

Biopressure feedback airbags are mainly used in medical fields, such as surgery, pain management, rehabilitation therapy, etc. By applying moderate pressure stimulation to the patient, the patient's pain can be effectively reduced and the treatment effect can be improved. At the same time, the biopressure feedback airbag can also be used in conjunction with sensors and other equipment to achieve real-time monitoring and feedback of the patient's pressure state.

The production process of the biopressure feedback airbag involves multiple links, and it is necessary to strictly control the quality of raw materials, production processes and product performance. Only in this way can the airbag be ensured to have good mechanical properties and biocompatibility, providing strong support for clinical treatment.
