Description

Technical Field

[0001] The utility model relates to the technical field of cerebral blood oxygen detection, in particular to a non-invasive cerebral blood oxygen detection head adapter. Background Art

[0002] A non-invasive brain blood oximeter is a device used to monitor the brain's oxygenation level, usually using optical technology. This device indirectly monitors the brain's oxygenation level by placing a sensor on the head and using infrared or near-infrared light to detect the oxygen content in the blood. The non-invasive brain blood oximeter can be monitored without the need to insert a sensor or catheter, so it is called a "non-invasive" technology. This technology has important application significance in neuroscience research, clinical diagnosis, and monitoring brain function status. The brain blood oximeter adapter is an adapter used to connect the brain blood oximeter device and the head. It is often used in neuroscience research or clinical diagnosis, and can help researchers or doctors monitor the brain's oxygenation level and understand the brain's activity. The design of the adapter ensures that the brain blood oximeter device can be accurately connected to the head to obtain accurate brain blood oximeter data.

[0003] In the prior art, when performing non-invasive cerebral blood oxygen detection, since there are a large number of detection heads, they need to be accurately attached to the designated positions. At the same time, patients have different body shapes, and medical staff often need to stick them one by one to the corresponding positions when connecting the detection heads. This process is cumbersome, time-consuming and labor-intensive, and can easily cause fatigue to medical staff. Therefore, the utility model provides a non-invasive cerebral blood oxygen detection head adapter to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a non-invasive brain blood oximetry detection head adapter is proposed. By passing the signal line through the threading tube and connecting the air pump to the inflation tube, the air pump can inject gas into the internal inflatable airbag, so that the detection head can fit closely to the patient's head, thereby significantly improving the detection efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A non-invasive cerebral blood oxygen detection head adapter, comprising an adapter mechanism, the adapter mechanism comprising a fixing cap, an air release valve, an outer connecting ring, a plurality of inflatable tubes, a plurality of inflatable airbags, a connecting trachea, a threading barrel, an inner connecting ring, a first limiting silicone sheet, a plurality of Velcro strips and a plurality of second limiting silicone sheets, the outer connecting ring, the threading barrel, the inner connecting ring and the first limiting silicone sheet constitute a threading mechanism;

[0007] A sponge pad is fixedly arranged inside the fixing cap near the lower end, connecting blocks are fixedly arranged on both sides of the lower end of the fixing cap, and a fixing strap is fixedly connected between the lower ends of the two connecting blocks;

[0008] Through the above technical solution, when the adapter is used, first place the detection head to be pasted inside the fixing cap near the threading barrel, then pass the signal line out from the inside of the threading barrel, and then connect the air pump to the inflation tube. At this time, after the air pump inputs gas into the internal inflation bag, the detection head can be firmly squeezed onto the patient's head, thereby improving the detection efficiency.

[0009] Furthermore, the plurality of inflatable airbags are evenly arranged inside the fixing cap, and the plurality of inflatable airbags are connected together through a plurality of connecting air pipes;

[0010] Through the above technical solution, when the inflation tube inflates the inflatable airbag, the gas can be evenly dispersed on multiple inflatable airbags through the connecting air tube, thereby improving the uniformity of the gas and allowing the detection head to fit the patient's head more closely.

[0011] Furthermore, the threading barrel is arranged inside the fixing cap, the outer connecting ring is fixedly arranged at one end of the threading barrel close to the outside, and the inner connecting ring is fixedly arranged at one end of the threading barrel close to the inside;

[0013] Furthermore, the threading mechanism is provided in plurality, and the plurality of threading mechanisms are evenly arranged inside the fixing cap;

[0014] Through the above technical solution, it is convenient to pass multiple signal lines through the inside of the fixing cap during non-invasive cerebral blood oxygen detection, thereby improving the detection efficiency.

[0015] Furthermore, a plurality of the first limiting silicone sheets and the second limiting silicone sheets are evenly arranged on the inner surface of the fixing cap;

[0016] Through the above technical solution, after the inflatable airbag is inflated, the first limiting silicone sheet and the second limiting silicone sheet can be compressed, and since the first silicone sheet and the second silicone sheet are harder in texture, the detection head can be tightly pressed against the patient's head.

[0017] Furthermore, a plurality of the Velcro strips are respectively fixedly arranged on the inner surfaces of a plurality of the second limiting silicone sheets;

[0018] Through the above technical solution, the detection head can be connected to the place where the threading mechanism is not provided through the Velcro, thereby improving the applicability of the adapter.

[0019] Further, the deflation valve is connected to one of the plurality of inflatable airbags, and the inflation tube is connected to one of the plurality of inflatable airbags;

[0020] Through the above technical solution, the inflatable airbag inside the adapter can be inflated through the inflation tube and deflated through the deflation valve, which facilitates the wearing and taking off effects.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a non-invasive brain blood oxygen detection head adapter. The adapter is equipped with multiple threading mechanisms inside. These mechanisms can accurately place the detection head inside the fixed cap to ensure that it is close to the threading barrel. When in use, the signal line passes through the threading barrel. After the air pump is connected to the inflation tube, the air pump injects gas into the internal inflatable airbag, so that the detection head fits closely to the patient's head, which significantly improves the detection efficiency and reduces the workload of medical staff.

[0023] 2. The utility model proposes a non-invasive brain blood oxygen detection head adapter. The adapter is internally provided with a fixing cap for fixing the detection head, and a fixing strap is provided at the lower end of the fixing cap, so that it is convenient for patients to wear it during the detection process and the wearing stability is improved. A sponge pad is also provided in the fixing cap to improve the comfort of the patient. BRIEF DESCRIPTION OF THE DRAWINGS
