Description

Technical Field

[0001] The invention relates to an image scanning system, and in particular to a brain near-infrared light image scanning system and a diagnostic method. Background Art

[0002] Near-infrared spectral imaging is an inspection method that uses infrared rays to image human tissues. Different tissues absorb infrared light of different wavelengths to different degrees. The remaining light waves after absorption by body tissues are received by light detectors installed outside the body, and images of human tissues are formed accordingly.

[0003] The light detector is set outside the body through a positioning device to receive the remaining light waves. There is a certain time difference between the emission and reception of the light waves. The positioning of the light detector needs to be maintained as much as possible within this time difference in order to obtain more accurate detection and imaging. Especially for brain scanning, the existing technology fixes the head with a head-mounted device. Due to the spacing of the hair and changes in facial expressions, it is easy to involve changes in the external skin, which in turn causes the position of the light detector on the head-mounted device to change, and the resulting scan image is extremely difficult to accurately judge.

[0004] To this end, technicians in this field have proposed a brain near-infrared light imaging scanning system and diagnostic method. In order to solve the problems of difficulty in locating hair intervals during head scanning and displacement of head-mounted light detectors due to skin movement, a structure that is easier to locate and less likely to move is studied, which makes it easier to obtain accurate scanning results. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a brain near-infrared light imaging scanning system and a diagnostic method. A positioning suction cup is arranged on the inner side of the existing mounting headgear through a rubber column to adsorb and position the headgear to the patient's skin. On the one hand, the positioning suction cup adsorption method has a good positioning effect and has strong stability when the patient has no facial expression changes. When the patient's skin is pulled, the shaking is limited to a smaller range through the rubber column. In addition, a rubber pad and a probe are arranged by installing a slide rail. The rubber pad is pressed against the human body to increase the contact area and increase the contact stability. The probe can be adjusted to be in close contact with the skin of different patients to ensure a good detection effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a brain near-infrared light imaging scanning system, including a headgear and a probe, the headgear is easy to wear and has elastic fabric with a stretching effect according to the head shape, and multiple probes are distributed on the headgear.

[0007] A common method in the prior art is to install a headgear to cover the patient's head, and install a probe on the inside to press against the patient's body to receive light waves. However, the existing equipment has the problem that the positioning between the patient's head and the headgear is not tight enough. The skin may be pulled due to changes in the patient's facial expression, causing the headgear with unstable positioning to slip. The unstable positioning of the probe will affect the detection and is not conducive to the doctor's diagnosis. Therefore, technical personnel in this field have made some improvements to the equipment in the prior art to try to alleviate or even overcome such problems.

[0008] A positioning suction cup is fixed on the inner side of the mounting headgear, which is adsorbed on the skin for positioning. The positioning suction cup that is directly adsorbed to the patient's exposed skin has high stability. When the patient maintains a facial expression, the entire mounting headgear will not be deformed due to body shaking, causing the probe position to move and affecting the reception of light waves.

[0009] A mounting rail is fixed on the side of the mounting headgear, and a rubber pad is arranged on the mounting headgear through the mounting rail. The probe is arranged on one side of the rubber pad. The mounting headgear is pressed against the patient's body through the rubber pad, thereby increasing the contact area between the device and the patient's skin and hair, and also increasing the friction. Under the action of the rubber pad, the probe can easily maintain the original mounting position without moving.

[0010] In addition, the rubber pad is in close contact with the patient's body, and the contact strength between the probe fixed on one side and the scalp can be adjusted to ensure that the probe is in close contact with the patient's body to receive light waves. It is suitable for adaptive use by patients of different age groups, and there will be no problem that the local probe cannot be well pressed against the patient's body.

[0011] Preferably, elastic straps are symmetrically fixed on both sides of the mounting headgear, and after the device is put on the patient's head, it is connected and fixed at the chin through the elastic straps.

[0012] The inner wall of the mounting headgear is fixedly connected with a rubber column, and the positioning suction cup is fixed to the mounting headgear through the rubber column. The rubber column has a certain deformation ability. When the patient's facial expression changes and affects the local skin, because the friction between other parts of the patient's body through the positioning suction cup and the rubber pad is relatively large, the positioning suction cup at this place will deviate along with the pulling of the skin and unload the force through the bending of the rubber column, thereby ensuring the stable installation of other positions and even the entire equipment relative to the patient's head.

[0013] Preferably, a slider is slidably connected to the inner side of the mounting rail, and the rubber pad is slidably arranged on the inner side of the mounting head cover through the slider. The rubber pad is slidably arranged on the inner side of the mounting rail through the slider. After the mounting head cover is set, the position of the slider can be appropriately moved to make the probe more convenient and evenly distributed to obtain a more comprehensive detection image.

[0014] A telescopic rod is fixedly connected to the side of the slider. A rubber pad is fixedly connected to the extended end of the telescopic rod. A probe is fixedly connected to the side of the rubber pad. The telescopic rod is used for the extended installation of the rubber pad and the probe, and ensures that the probe presses tightly against the patient's head for light wave absorption, avoiding the problem that the probe cannot press tightly against the patient's skin and natural light affects the detection.

[0015] Preferably, a rubber tube is also fixedly connected between the telescopic rod and the slider. The hollow rubber tube plays the same role as the rubber column, and the rubber tube has a better use effect than the rubber column. At the same time, other fixing structures are arranged inside the rubber tube. With the cooperation of the two, when the upper and lower structures of the telescopic rod are stressed, the telescopic rod can reduce the influence on the other end by deflection.

[0016] A first spring is arranged inside the telescopic rod. By pressing against the extended end of the telescopic rod with the first spring, it ensures the pressing contact of the probe against the patient's skin. Even when the installation structure deflects due to external force, it can still press tightly against the patient's body as much as possible through the elastic force of the first spring, ensuring the reception efficiency of the remaining infrared light waves.

[0017] Preferably, the fixed end of the telescopic rod penetrates and is provided with a tightening screw through a bearing. A carry block is sleeved inside the telescopic rod. The tightening screw penetrates the carry block and is threadedly connected to it. By adjusting the tightening screw, the installation position of the carry block inside the telescopic rod can be adjusted, further adjusting the pressing force of the rubber pad against the patient's body, and ensuring the pressing contact between the probe and the patient's body.

[0018] An intermediate block is arranged on the side of the carry block close to the extended end of the telescopic rod. Two first springs are respectively arranged between the extended end of the telescopic rod, the intermediate block and the carry block. Electric contact elastic sheets are fixed on the sides of the carry block and the intermediate block close to each other. The two electric contact elastic sheets are electrically connected to a lamp bead.

[0019] During the adjustment of the position of the carry block by the tightening screw, as the installation position of the carry block inside the telescopic rod changes, the pressure on the first spring also changes. However, the pressure exerted by the carry rod on the patient's body cannot be simply judged by asking. Therefore, the intermediate block pressed by the first spring is designed. When the first spring is compressed to a certain extent, the electric contact elastic sheets arranged on the sides of the carry block and the intermediate block close to each other come into contact, turning on the circuit of the lamp bead, and the lamp bead lights up, thereby judging the magnitude of the pressure exerted by the rubber pad on the patient's skin.

[0020] The tightening screw penetrates the intermediate block and is slidably connected to it. The slidable connection between the tightening screw and the intermediate block can realize the change in the distance between the intermediate block and the carry block when the pressure of the first spring changes, and judge the magnitude of the acting force received by the telescopic rod according to this distance change.

[0021] Preferably, a guiding block is also fixedly connected to the side surface of the carry block and the middle block. The carry block and the middle block are slidably connected to the telescopic rod through the guiding block. On the one hand, the guiding block ensures that the carry block makes a carry as the adjusting screw rod is adjusted. On the other hand, it ensures that the angle between the carry block and the middle block does not change during the adjustment process, which affects the elastic coefficient of the first spring.

[0022] Preferably, a carry rod is inserted into the side surface of the slider. One end of the carry rod passing through the side wall of the slider is fixedly connected with a rubber wedge block. The carry end of the carry rod passes through the side wall of the slider and abuts against the inner wall of the installation slide rail through the rubber wedge block for positioning.

[0023] When the position of the slider needs to be adjusted, the carry rod needs to be pressed to make it carry towards the inside of the slider. The rubber wedge block at the carry end of the carry rod disengages from the abutting contact with the installation slide rail. The rubber wedge block at the extended end of the carry rod increases the friction force, and the slider is positioned through this friction force.

[0024] Preferably, a limiting groove is provided on the inner side of the installation slide rail corresponding to the rubber wedge block. The contact area between the installation slide rail and the rubber wedge block is increased through the limiting groove to ensure the positioning effect on the slider.

[0025] A second spring is tightly sleeved on the side surface of the carry rod. Under the elastic force of the second spring, the slider is stably positioned.

[0026] Preferably, a dial block is fixedly connected to the side surface of the carry rod away from the rubber wedge block. A carry groove is provided on the side surface of the slider corresponding to the dial block. The dial block passes through the carry groove and is slidably connected to the slider. The setting of the dial block facilitates the operation of the carry rod.

[0027] A diagnostic method for a brain near-infrared light imaging scanning system includes the following steps:

[0028] S1. After putting the installation headgear on the head of the patient to be examined, pull the installation headgear to adjust the relative position of the positioning suction cup and the patient's head accordingly. The positioning suction cup is attached to the exposed skin of the patient to help the installation headgear fit and position with the patient.

[0029] S2. Slide and adjust the position of the slider within the adjustment range of the installation slide rail. By the position of the slider positioning probe relative to the patient's head, it is beneficial to obtain complete detection data. In addition, the extension of the telescopic rod is adjusted by the adjusting screw rod to ensure the abutting contact between the rubber column at the end of the extension rod and the patient's head, increasing the friction force to ensure the stable installation of the device. At the same time, it also ensures the abutting contact between the probe and the patient's skin. In addition, the possibility of the device shaking and displacing can be reduced through the friction force, and the installation of the device on the patient's head is completed.

[0030] S3. Start the infrared light emission of the device and the probe to receive light waves. During the process, the fixing effect between the positioning suction cup and the patient's skin is good. At the same time, adjust the installation position of the probe relative to the patient by installing a slide rail. In addition, increase the friction between the probe installation structure and the patient's body through a rubber pad to avoid the change of the probe installation position caused by the movement of the patient's facial expression affecting the skin.

[0031] The present invention discloses a near-infrared light imaging scanning system and a diagnosis method for the brain, and the beneficial effects thereof are as follows:

[0032] 1. For the near-infrared light imaging scanning system and the diagnosis method for the brain, a positioning suction cup connected by a rubber column is arranged on the inner side of the existing headgear. The positioning suction cup adsorbs and positions the exposed skin of the patient, and the positioning effect is good, and the overall displacement of the device is not easy to occur. In addition, the rubber column can deflect when the local skin of the patient is pulled to offset part of the displacement effect. Further, the probe is tightly installed through the installation slide rail and the rubber pad. The rubber pad increases the friction between the device and the patient's body. The telescopic rod fixed by the rubber tube can not only adjust the extension length of the rubber pad, but also realize the unloading installation at both ends of the telescopic rod, and ensure the tight installation of the probe on the side of the telescopic rod and the patient's body, so as to ensure the accurate absorption of the remaining infrared light.

[0033] 2. For the near-infrared light imaging scanning system and the diagnosis method for the brain, the installation headgear itself is made of elastic fabric, and the elastic strap is combined to facilitate the installation on the heads of patients of any age group. The positioning suction cup connected by the rubber column makes the device have strong resistance to the change of the patient's facial expression. When the local skin is pulled, the positioning suction cup at that place moves with the skin. Due to the pulling effect between other multiple positioning suction cups, the positioning suction cup at this position unloads the force by bending the rubber column, and tries to minimize the impact on the overall device, thereby increasing the installation stability of each probe.

[0034] 3. For the near-infrared light imaging scanning system and the diagnosis method for the brain, a telescopic rod is arranged through the installation slide rail on the side of the installation headgear, and then the probe and the rubber pad are installed through the telescopic rod. The rubber pad is in tight contact with the patient to increase the friction. This frictional force can unload the force by bending the rubber tube when the installation headgear is pulled by an external force, ensuring the tight contact between the probe and the patient. In addition, the telescopic rod can ensure the adaptive use of the device for patients of all age groups, and ensure the installation position and tight effect of each probe.

[0035] 4. For the near-infrared light imaging scanning system and the diagnosis method for the brain, the telescopic rod is provided with a tightening screw to adjust the extension length, which not only makes the device more adaptable in use, but also can monitor the magnitude of the tightening force between the device and the patient's body through the intermediate block, the power connection elastic sheet and the lamp bead arranged inside it, ensuring comfort and the accuracy of detection at the same time.

Specific embodiments

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0045] An embodiment of the present invention discloses a near-infrared light imaging scanning system and a diagnosis method for the brain;

[0046] According to the attached Figure 1As shown, it includes a mounting headgear 1 and a probe 2. The mounting headgear 1 is a headgear made of stretchable elastic fabric that is convenient to wear and conforms to the head shape. Multiple probes 2 are distributed on the mounting headgear 1.

[0047] The structure in which the mounting headgear 1 wraps around the patient's head and the probe 2 is installed on its inner side to press against the patient's body to receive light waves is a common method in the prior art. However, in existing devices, the positioning between the device and the patient's head is not tight enough. It may be due to the movement of the patient's facial expressions that pulls the skin, resulting in unstable positioning and the sliding of the mounting headgear 1. The unstable positioning of the probe 2 will affect the detection and is not conducive to the doctor's diagnosis. Therefore, those skilled in the art have made some improvements to the existing devices to alleviate or even overcome such problems.

[0048] A positioning suction cup 3 is fixed on the inner side of the mounting headgear 1. The positioning suction cup 3 adsorbs and positions on the skin, and the direct adsorption with the patient's bare skin has high stability. When the patient maintains a facial expression, the whole mounting headgear 1 will not be deformed due to the problem of body shaking, and the position of the probe 2 will not be affected and move.

[0049] An installation slide rail 4 is fixed on the side of the mounting headgear 1. The probe 2 is adjustably installed through the installation slide rail 4, so that the probe 2 can be conveniently adjusted to press against various positions of the patient's head for detection to obtain a complete image.

[0050] According to the attached Figure 2 and the attached Figure 3 As shown, a rubber pad 5 is provided on the mounting headgear 1 through the installation slide rail 4. The mounting headgear 1 presses against the patient's body through the rubber pad 5, increasing the contact area between the device and the patient's skin and hair, and also increasing the friction.

[0051] The probe 2 is arranged on one side of the rubber pad 5. The rubber pad 5 increases the friction with the skin and hair and adjusts the pressing contact between the probe 2 and the scalp. Under the action of the rubber pad 5, the probe 2 is relatively easy to maintain its original installation position and will not move.

[0052] Elastic straps 6 are symmetrically fixed on both sides of the mounting headgear 1. After the mounting headgear 1 is set on the patient's head, it is reinforced through the elastic straps 6.

[0053] The inner wall of the mounting headgear 1 is fixedly connected with rubber columns 7. The positioning suction cup 3 is fixed to the mounting headgear 1 through the rubber columns 7. The rubber columns 7 are relatively soft and deformable connection structures, realizing the movable installation of the positioning suction cup 3 relative to the mounting headgear 1. Since the positioning suction cup 3 adsorbs to the patient's skin, when the patient makes facial expression changes, it will involve the facial skin. The positioning suction cup 3 in the changing range will inevitably move with the skin. Through the connection relationship, the movement of the entire mounting headgear 1 can be involved. However, due to the adsorption and positioning of other positioning suction cups 3 and the connection of the rubber columns 7, when the positioning suction cup 3 pulls the mounting headgear 1 through the rubber columns 7, deformation can occur at the rubber columns 7 to buffer the pulling force, ensuring the relatively stable installation of other parts of the mounting headgear 1.

[0054] The inner side of the mounting slide rail 4 is slidably clamped with a slider 8. The rubber pad 5 is slidably arranged inside the mounting headgear 1 through the slider 8. The rubber pad 5 slidably arranged through the slider 8 can adjust the installation position within a certain range according to the usage needs, thereby achieving greater applicability and helping to perform the covering imaging of the entire brain.

[0055] The side of the slider 8 is fixedly connected with a telescopic rod 9. The rubber pad 5 is fixedly connected to the extended end of the telescopic rod 9. The probe 2 is fixedly connected to the side of the rubber pad 5. The telescopic rod 9 can be extended through telescopic movement to ensure the tight contact between the rubber pad 5 and the patient's body, thereby ensuring that the probe 2 tightly contacts the human body to receive infrared light signals.

[0056] A rubber tube 10 is also fixedly connected between the telescopic rod 9 and the slider 8. The function of the rubber tube 10 is similar to that of the above-mentioned rubber column 7, but under the action of its internal fixed structure, it can buffer the force through deflection and deformation within a certain range to maintain the stable setting of the structure.

[0057] According to the attachment Figure 4 As shown, a first spring 11 is arranged inside the telescopic rod 9. By pressing against the telescopic rod 9 through the first spring 11, it is ensured that the probe 2 at the end of the telescopic rod 9 tightly contacts the patient's body.

[0058] The fixed end of the telescopic rod 9 penetrates and is provided with a tightening screw 12 through a bearing. A carry block 13 is sleeved inside the telescopic rod 9. The tightening screw 12 penetrates the carry block 13 and is threadedly connected thereto. Rotating the tightening screw 12 can drive the carry block 13 to change its installation position along the direction of the telescopic rod 9 through the threaded connection relationship, thereby applying different magnitudes of elastic force to the first spring 11 inside it, ensuring the appropriate length extension of the telescopic rod 9 and ensuring the appropriate force of the probe 2 to tightly contact the patient's body.

[0059] On one side of the carry block 13 close to the extending end of the telescopic rod 9, an intermediate block 14 is provided. Two first springs 11 are respectively arranged between the extending end of the telescopic rod 9, the intermediate block 14 and the carry block 13. The tightening screw 12 passes through the intermediate block 14 and is slidably connected thereto. When the tightening screw 12 is rotated, the carry block 13 is driven to move through the threaded connection relationship. Because of the change in the position of the carry block 13 relative to the telescopic rod 9, the deformation amount of the first spring 11 inside it changes, thereby changing the distance between the carry block 13 and the intermediate block 14. The tightness of the equipment installation is monitored through this distance.

[0060] According to the attached Figure 5 and the attached Figure 6 As shown, on the sides of the carry block 13 and the intermediate block 14 close to each other, a power connection elastic sheet 15 is fixed. The two power connection elastic sheets 15 are electrically connected to a lamp bead 16. After the distance between the carry block 13 and the intermediate block 14 is reduced to a certain extent, the two side power connection elastic sheets 15 are pressed into tight contact, connecting the circuit of the lamp bead 16. When the lamp bead 16 lights up, it means that the probe 2 has been tightly installed, and it will not affect the detection due to the tightness of the installation of the probe 2, nor will it cause a bad user experience to the user.

[0061] On the sides of the carry block 13 and the intermediate block 14, a guiding block 17 is also fixedly connected. The carry block 13 and the intermediate block 14 are slidably connected to the telescopic rod 9 through the guiding block 17. Through the guiding block 17, it is ensured that the carry block 13 makes a carry as the tightening screw 12 rotates, rather than rotating with the tightening screw 12. The intermediate block 14 is provided with the guiding block 17 to prevent the angle change between it and the carry block 13 from affecting the elastic coefficient of the first spring 11.

[0062] On the side of the slider 8, a carry rod 18 is inserted. One end of the carry rod 18 passing through the side wall of the slider 8 is fixedly connected with a rubber wedge block 19. The carry end of the carry rod 18 passes through the side wall of the slider 8 and is pressed against the inner wall of the installation slide rail 4 through the rubber wedge block 19 for positioning.

[0063] The carry rod 18 is pressed against the inner wall of the installation slide rail 4 through the rubber wedge block 19 at its end, and the slider 8 is positioned through the friction force between the two. The positioning method is simple and the positioning effect is obvious.

[0064] On the inner side of the installation slide rail 4, a limiting groove 20 is provided corresponding to the rubber wedge block 19, and the contact area between the installation slide rail 4 and the rubber wedge block 19 is increased through the limiting groove 20, thereby ensuring the friction force between the two.

[0065] A second spring 21 is tightly sleeved on the side of the carry rod 18. The second spring 21 presses against the carry rod 18 to ensure the extended pressing state of the carry rod 18 against the installation slide rail 4.

[0066] On the side of the end of the carry rod 18 away from the rubber wedge 19, a dial block 22 is fixedly connected. A carry slot 23 is provided on the side of the slider 8 corresponding to the dial block 22. The dial block 22 passes through the carry slot 23 and is slidably connected to the slider 8.

[0067] When pressing the dial block 22 with a finger, pressure can be applied to the second spring 21 on the side of the carry rod 18. The second spring 21 deforms, and the carry rod 18 advances inward of the slider 8. The rubber wedge 19 at the end of the carry rod 18 is disengaged from the state of being tightly pressed against the inner wall of the installation slide rail 4, facilitating the movement and positioning of the slider 8.

[0068] A diagnostic method for a brain near-infrared light imaging scanning system includes the following steps:

[0069] S1. After putting the installation headgear 1 on the head of the patient to be examined, pull the installation headgear 1 to correspondingly adjust the relative position of the positioning suction cup 3 and the patient's head. The positioning suction cup 3 is attached to the exposed skin of the patient to help the installation headgear 1 fit and position with the patient.

[0070] S2. Slide and adjust the position of the slider 8 within the adjustment range of the installation slide rail 4 to position the probe 2 relative to the patient's head through the slider 8, which is beneficial for obtaining complete detection data. In addition, the extension of the telescopic rod 9 is adjusted by the tightening screw 12 to ensure the tight contact between the rubber pad 5 at the end of the telescopic rod 9 and the patient's head, increasing the friction force to ensure the stable installation of the device while also ensuring the tight contact between the probe 2 and the patient's skin. In addition, the possibility of the device shaking and displacing can be reduced through the friction force, and the installation of the device on the patient's head is completed.

[0071] S3. Start the infrared light emission of the device and the probe 2 to receive light waves. During the process, the fixing effect between the positioning suction cup 3 and the patient's skin is good. At the same time, the installation position of the probe 2 relative to the patient is adjusted through the installation slide rail 4. In addition, the friction force between the installation structure of the probe 2 and the patient's body is increased through the rubber pad 5 to avoid the change of the installation position of the probe 2 caused by the movement of the patient's facial skin due to facial expressions.

[0072] In the brain near-infrared light imaging scanning system and diagnostic method, a positioning suction cup 3 connected by a rubber column 7 is arranged inside the existing installation headgear 1. The positioning suction cup 3 adsorbs and positions with the exposed skin of the patient, and the positioning effect is good and the overall displacement of the device is not likely to occur. In addition, the rubber column 7 can deflect when the local skin of the patient is pulled to offset part of the displacement influence. Further, the probe 2 is tightly installed through the installation slide rail 4 and the rubber pad 5. The rubber pad 5 increases the friction force between the device and the patient's body. The telescopic rod 9 fixed by the rubber tube 10 can not only adjust the extension length of the rubber pad 5, but also realize the unloading installation at both ends of the telescopic rod 9, and ensure the tight installation of the probe 2 on the side of the telescopic rod 9 with the patient's body, ensuring the accurate absorption of the remaining infrared light.

[0073] Furthermore, the mounting headgear 1 itself is made of elastic fabric, which, combined with the elastic strap 6, facilitates the installation on the heads of patients of any age. The positioning suction cups 3 connected by the rubber posts 7 enable the device to have a strong resistance to changes in the facial expressions of patients. When the local skin is pulled, the positioning suction cups 3 at that position move along with the skin. Due to the pulling effect among the other multiple positioning suction cups 3, the positioning suction cups 3 at this position unload the force by bending the rubber posts 7, minimizing the impact on the overall device, thereby increasing the installation stability of each probe 2.

[0074] Still further, the telescopic rod 9 is arranged through the mounting slide rail 4 on the side of the mounting headgear 1, and the probe 2 and the rubber pad 5 are installed through the telescopic rod 9. The rubber pad 5 being in tight contact with the patient can increase the friction force. This frictional effect can unload the force by bending the rubber tube 10 when the mounting headgear 1 is pulled by an external force, ensuring the tight contact between the probe 2 and the patient. In addition, the telescopic rod 9 can ensure the adaptable use of the device for patients of all ages, ensuring the installation position and the tight contact effect of each probe 2.

[0075] Even further, the telescopic rod 9 is provided with a tightening screw 12 to adjust the extension length, which not only makes the device more adaptable in use, but also can monitor the magnitude of the tightening force between the device and the patient's body through the intermediate block 14, the power connection elastic sheet 15 and the lamp bead 16 arranged inside it, ensuring comfort while also ensuring the accuracy of the detection.
