Disposable SpO2 Sensor plays an important role in the field of medical monitoring, and the biocompatibility of its materials is a crucial issue.
In terms of composition, disposable SpO2 Sensor usually includes a part that contacts the skin and an internal electronic sensing component. The materials of the part that contacts the skin mainly include an adhesive layer and a shell material. Common adhesive layer materials include medical-grade adhesives, which are generally specially formulated. Good medical adhesives perform well in terms of biocompatibility, and most of them are hypoallergenic. This is because their ingredients are screened to avoid common allergens such as latex to reduce the risk of allergic reactions in patients' skin.
The shell material is mostly made of medical-grade plastics, such as polycarbonate or medical-grade silicone. Polycarbonate has good physical properties and can provide protection for the optical and electronic components inside the sensor. At the same time, it has good chemical stability and is not easy to react chemically with secretions on the skin surface or substances in the external environment. Medical-grade silicone is soft and elastic, and has minimal irritation to the skin. It can adapt to skin surfaces of different shapes to ensure that the sensor fits well with the skin, while not causing wear to the skin due to hard or rough surfaces.
In terms of the sensor's sensing components, the internal optical components and electronic circuits are usually sealed in the housing to avoid direct contact with human tissue. However, when designing, the safety of the material must also be considered to prevent the leakage of harmful substances during use. For example, the welding materials on the circuit board must meet strict medical safety standards to ensure that even if the sensor is accidentally damaged, it will not cause harm to the patient.
The biocompatibility of the Disposable SpO2 Sensor material is the result of a comprehensive consideration. Only by ensuring the safety and biocompatibility of the material from contact with the skin to the internal components can it safely and effectively play its blood oxygen saturation monitoring function in clinical use and avoid unnecessary health risks to patients due to material problems.
