Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a repetitive non-invasive brain blood oxygen detection head with a wrapping structure. Background Art

[0002] Blood oxygen saturation, also known as blood oxygen, is one of the most important basic physiological parameters in the clinical medical field, especially the blood oxygen saturation of the brain. During clinical diagnosis and treatment, patients often need to monitor the brain's blood oxygen saturation in a timely manner to ensure their safety. The detector head is the core component of the blood oxygen detection device. Among them, the non-invasive brain blood oxygen detection head has been widely used in medical practice due to its convenience and non-invasiveness.

[0003] As for the current brain blood oxygen detection head, it is generally composed of a protective cover with an adhesive pad on the outside and a sensor sheet for detection on the inside. The adhesive pad and the protective cover are often designed as a fixed integrated structure. Since the bonding time of the adhesive pad is often short, in order to ensure the stability of the detection head during use, once the adhesive pad fails, it is often necessary to replace the entire detection head, which may greatly increase the cost of brain blood oxygen detection. The sensor sheet and the protective cover are usually directly fixed. When there is a problem with one part of the sensor sheet or the protective cover, it is often necessary to replace the entire device, which may further increase the cost of using the device.

[0004] Therefore, the utility model provides a repetitive non-invasive brain blood oxygen detection head with a wrapping structure to solve the problems raised in the above background technology. Utility Model Content

[0020] Furthermore, two limit grooves are provided on the inner surface of the protective soft cover near the front and rear ends, and the four limit blocks are respectively engaged in the four limit grooves;

[0021] Through the above technical solution, the limiting groove is mainly used for limiting to ensure the fixing effect of the fixing clip on the adhesive pad, and the upper and lower surfaces of the limiting block are curved to facilitate the telescopic movement of the limiting block.

[0022] Furthermore, the upper ends of the two adjusting springs are fixedly connected to the protective soft cover, and the opposite ends of the four telescopic springs are fixedly connected to the inside of the fixing clip;

A protective mechanism is provided in the cerebral blood oxygen detection head. During use, the protective soft cover in the protective mechanism can not only protect the internal structure, but also fit the patient's forehead well. The rotating arc plate can facilitate the loading and unloading of the sensing piece. In this way, after the sensing piece or the protective soft cover fails, the other part can be continued to be used. While protecting the sensing structure, the cost of cerebral blood oxygen detection is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
