Description

Technical Field

[0001] The utility model relates to the technical field of near-infrared brain function imaging brackets, and specifically, to a near-infrared brain function imaging probe holder. Background Art

[0002] In the field of medical imaging, especially in brain function imaging technology, infrared imaging technology has been widely used due to its non-invasive, safe and real-time monitoring characteristics. As an important device for supporting and fixing the probe, the design of the near-infrared brain function imaging probe holder has a direct impact on the imaging quality. The probe holders in the prior art, such as the auxiliary device for near-infrared data acquisition and the near-infrared brain function imaging system with the publication number CN215651048U, usually adopt a fixed structure and are difficult to adapt to the changes in the head shapes of different patients, resulting in problems such as inaccurate positioning and poor stability during the imaging process. Most of the existing probe holders are rigid structures and cannot be adjusted according to the curvature of the patient's head, which may lead to poor contact between the probe and the patient's head and affect the imaging quality. The installation and fixation process of the probe may involve multiple steps and require professional operation, which not only increases the difficulty of use but also may prolong the waiting time of the patient. The fixation method of the existing probe holder may not be stable enough and is prone to displacement during the imaging process, affecting the accuracy and reliability of the data. Due to the lack of effective weight reduction and buffering designs, especially during long-term monitoring, the existing probe holder may cause discomfort to the patient.

Detailed implementation manners

[0023] The following will further illustrate the present invention in conjunction with the attached Figures 1 - 4 drawings and implementation manners.

[0024] The near-infrared brain function imaging probe holder includes a bracket 1. The bracket 1 is square and provided with a plurality of openings. The bracket 1 fixedly connects a connecting frame 6 through a plurality of support rods 11. Both the bracket 1 and the connecting frame 6 are elastic and can generate elastic deformation when contacting the patient's head to fit the head curvature. The four corners of the connecting frame 6 are respectively fixedly connected to extension arms 2;

[0025] The outer ends of each extension arm 2 are respectively provided with a cross-shaped keyway 21 and a group of uniformly arranged card slots 22. The card slots 22 are arranged in a cross shape and each card slot 22 is respectively arranged between the included angles of the cross-shaped keyway 21;

[0026] The clamping block 4 matches the cross-shaped keyway 21, and a near-infrared brain function probe 5 is fixedly arranged at the lower end of the clamping block 4.

[0027] In this embodiment, the middle part of the bracket 1 fixes the connecting frame 6 through the connecting rod 12. The connecting rod 12 is made of an elastic material. The clamping block 4 can pass through the cross-shaped keyway 21 to realize the installation of the near-infrared brain function probe 5. The protruding arm 2 serves as a support to support the clamping block 4.

[0028] The clamping block 4 includes several groups of protruding rods 41 arranged in a cross shape, a fixing column 42, a nut 43, and a bolt 44. The upper end of the protruding rod 41 fixes the bolt 44, and the lower end of the protruding rod 41 fixes the near-infrared brain function probe 5. There are 3 groups of protruding rods 41, which are evenly fixed on the circumferential arc surface of the protruding rod 41 from top to bottom.

[0029] In this embodiment, the protruding rod 41 of the clamping block 4 can pass through the cross-shaped keyway 21. After placing the protruding arm 2 between the protruding rod 41 and the bolt 44 and tightening the nut 43, the fixing of the clamping block 4 can be realized, and then the fixing of the near-infrared brain function probe 5 can be realized.

[0030] Both ends of the bracket 1 are respectively provided with connection ports 13 through which the elastic strap 3 passes. One end of the elastic strap 3 is connected to the self-adhesive one 32 and the self-adhesive two 33. After the self-adhesive two 33 at one end of the elastic strap 3 passes through the connection port 13, it can be adhesively connected to the self-adhesive two 33. The other ends of the two elastic straps 3 are respectively connected to the self-adhesive three 31, and the two self-adhesive three 31 are adhesively connected.

[0031] In this embodiment, the elastic strap 3 can be detached through the self-adhesive one 32 and the self-adhesive two 33. After each elastic strap 3 is installed, the two self-adhesive three 31 are adhesively connected to fix it on the patient's head.

[0032] The vertical distance between each group of protruding rods 41 is greater than the thickness of the protruding arm 2, ensuring that when the protruding arm 2 is located between each group of protruding rods 41, the clamping block 4 can rotate circumferentially. A limiting block 411 is respectively arranged at the outer end of the lower side of each protruding rod 41. The limiting block 411 matches the card slot 22. The limiting block 411 is slightly larger than the card slot 22 and can be snapped into the card slot 22. The limiting block 411 is a rubber block with elasticity and undergoes elastic deformation when snapped into the card slot 22 for fixing the clamping block 4.

[0033] In another embodiment, a limiting block 411 is provided. The limiting block 411 can be stuck in the card slot 22. By snapping the limiting block 411 into the card slot 22 on the protruding rods 41 at different heights, the height position of the near-infrared brain function probe 5 can be adjusted to adapt to the heads of different patients.

[0034] A group of notches are provided on the protruding arm 2 to reduce the self-weight of the protruding arm 2.

[0035] During use, pass the elastic strap 3 through the connection ports 13 at both ends of the bracket 1. Connect one end of the elastic strap 3 to the self-adhesive one 32 and the self-adhesive two 33, pass the self-adhesive two 33 through the connection port 13 and bond it to the other end for fixation. Connect the other end of the elastic strap 3 to the two self-adhesive three 31 and bond them together to fix the probe holder on the patient's head. According to the shape of the patient's head, appropriately adjust the bracket 1 and the connecting frame 6 to make them elastically deformed to better fit the curvature of the patient's head. According to the height of the patient's head, unscrew the nut 43, select a suitable extension rod 41, turn the extension rod 41 so that the limit block 411 aligns with the card slot 22, and snap the limit block 411 into the card slot 22 on the extension arm 2. By adjusting the extension rods 41 at different heights, the height position of the near-infrared brain function probe 5 can be adjusted. When adjusting to the outermost extension rod 41, fix the chuck 4 with bolts 44 and nuts 43 to adapt to the heads of different patients and ensure that the contact position of the near-infrared brain function probe 5 with the patient's head is correct to obtain the best imaging effect. Start the near-infrared brain function imaging device and start brain function imaging. According to the needs during the imaging process, the position of the near-infrared brain function probe 5 can be finely adjusted by adjusting the elastic strap 3 to drive the bracket 1 and the like as a whole to ensure the accuracy of imaging.
