Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a meridian tester. Background Art

[0002] In traditional Chinese medicine theory, meridians and acupoints are key parts for traditional Chinese medicine diagnosis. In practice, a meridian pen is often used to detect whether the acupoints and meridians are in a normal state. For normal people, the temperature tolerance of homologous acupoints on the left and right sides of the body is about the same. However, if there is an abnormality in the human body, the heat tolerance of the acupoints on both sides of the body will change, differing by one or several times. Therefore, based on the changes in the heat tolerance of the corresponding acupoints on both sides and the imbalance between the left and right sides of the human body, the parts, deficiency, and excess of diseases can be distinguished, serving as a reference for diagnosis and acupoint selection.

[0003] Chinese Patent CN213129429U discloses a heat sensation measurement instrument, which is essentially a meridian pen. It is provided with a heating head and a key switch. When in use, medical staff hold the meridian pen and press it against the well acupoint corresponding to the patient's finger. When the patient reaches the heat tolerance limit time, they inform the medical staff, and the medical staff quickly press the key switch to record the time to obtain the heat tolerance of this acupoint. Then, the heat tolerance of the acupoints on another finger is measured in the same steps. Finally, after measuring the left and right hands, analysis and comparison are carried out. Since the heating head can only be pressed against one acupoint at a time and requires medical staff to hold the meridian pen for operation beside, the measurement efficiency is not high. Moreover, since the hand shapes and finger lengths of each person are different, the positions of the acupoints are also different, and there is currently no device on the market that can simultaneously measure the heat tolerance of multiple fingers. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a specific sensory meridian tester that can simultaneously measure multiple fingers and does not require medical staff to time.

Finger placement grooves for positioning fingers and a palm placement groove for positioning the palm are formed between the finger separation blocks;

[0008] The finger detection component includes finger sleeves corresponding to each finger. The finger sleeves are elastic and are provided with a length detection component, a heating head, and a finger sensor therein. The length detection component is used to detect the length of the finger. The heating head on each finger sleeve is arranged corresponding to the acupoints on the finger. The finger sensor is used to detect whether there is a finger in the finger sleeve and emits a second signal when triggered; a guide block is fixed on the dorsal side of the finger sleeve;

The lead screw is arranged along the extension direction of the finger placement groove, and the guide block is meshed and matched with the lead screw;

[0010] The detection component, the heating head, the finger sensor, and the rotating component are all electrically connected to the host; when the detection component moves with the finger sleeve to the fingertip, it emits a first signal. The host calculates the length of the finger according to the first signal and controls the rotating component to continue rotating to move all the finger sleeves to the calculated target position. Then, while starting to time, it controls the heating head to heat up. After receiving the second signal of a certain finger sensor, it records the time and records this time as the heat resistance of the finger corresponding to this finger sensor; a touch screen and a speaker are arranged on the host and it is equipped with supporting software. The heat resistance of each finger well point and the difference and ratio of the heat resistance of the two corresponding same-name acupoints on the left and right can be displayed on the touch screen. The speaker and the touch screen will give voice prompts for each step.

[0011] Further, the detection component includes a light source and a photosensitive sensor arranged oppositely, and the starting position of the detection component is close to the palm placement groove.

[0014] Further, the lower end of the guide groove is in sliding contact with the hand placement plate.

[0015] Further, a vertical frame is arranged on the hand placement plate. Self-winding wire reels corresponding to the positions of each finger placement groove and a pressing block for locking the self-winding wire reels are arranged on the vertical frame. A pushing component is arranged at intervals on one side of each self-winding wire reel. The pushing component pushes the pressing block to tightly press against the self-winding wire reel. A pull wire is connected to the self-winding wire reel, and the lower end of the pull wire is connected to the finger sleeve.

[0016] Furthermore, the finger sleeve includes a hard first sleeve and an elastic second sleeve, the opposite surfaces of the first sleeve and the second sleeve can be abutted together, the detection component is arranged on the first sleeve and the bottom surface of the first sleeve is provided with a front block engaged with the screw rod, the heating head and the finger sensor are arranged on the second sleeve and the guide block with a guide groove is arranged on the second sleeve, the lower end of the pull wire is connected to the second sleeve, and the end of the first sleeve facing the second sleeve is provided with at least two baffles that can be stuck on the left and right inner sides of the second sleeve to prevent the width of the internal space of the sleeve from being reduced.

[0017] Furthermore, an orientation hole is provided at one end of the second sub-sleeve facing the palm placement cavity, and an orientation strip which can be inserted into the orientation hole is provided on the finger block, and the orientation strip is gap-matched with the orientation hole.

[0018] Furthermore, the detection component also includes a top plate matched with the finger sleeve, and both ends of the top plate can be pressed against the top of the finger sleeve to open the finger sleeve to a state where a finger can be inserted.

[0019] Furthermore, a hand rest pad for supporting the hand is arranged on the hand rest plate.

[0020] The working principle of the present invention is to set the heating head on the finger sleeve, and then set the finger sensor and the length detection component on the finger sleeve, and put the finger sleeve on the finger after detecting the length of the finger, so that the heating head contacts the well point of the finger; when the patient feels that the heat tolerance has reached the limit, since the finger sleeve is fixed, the finger can be freed from the finger sleeve by moving the finger, and the finger sensor cannot detect the finger, but can send a signal. The host records the heat resistance time according to the signal as the heat resistance of the finger.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention realizes the detection of the heat resistance of the acupoints of multiple fingers by wearing special finger sleeves on the fingers, and can adapt to fingers of different lengths; the present invention is simple to operate, and can greatly improve the detection efficiency of the heat resistance of the acupoints of the meridians on the human hand. At the same time, medical staff do not need to hold the meridian pen to detect fingers one by one, and concentrate on listening to the patient's report, which reduces the work intensity and mental consumption of medical staff.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] As Figures 1 to 2 shown, a meridian tester includes a hand detection device and a main unit. The hand detection device includes a hand placement plate 1, a finger separation assembly, a finger detection assembly, and a driving mechanism arranged on the hand placement plate 1;

[0034] The finger separation assembly is used to position the spread and straightened fingers into a specified shape. The finger separation assembly includes a plurality of finger separating blocks 2 arranged at intervals on the hand placement plate 1. The finger separating blocks 2 are correspondingly arranged between the fingers and on both sides of the palm of the human hand. Finger placement grooves for positioning fingers and palm placement grooves for positioning the palm are formed between the finger separating blocks 2. The hand detection device can be divided into different sizes such as L, M, S, etc. according to the sizes of different human hands to better match hands of different sizes;

[0035] The finger detection component includes finger sleeves 3 provided corresponding to each finger. The finger sleeves 3 are elastic and are internally provided with a length detection component, a heating head 4, and a finger sensor 5. The length detection component is used to detect the length of the finger. The heating head 4 on each finger sleeve 3 is arranged corresponding to the acupoints on the finger. The heating head 4 can adopt a ceramic heating element or a metal heating head as in Chinese Patent CN213129429U. The finger sensor 5 is used to detect whether there is a finger in the finger sleeve 3 and emits a second signal when the finger sensor 5 is triggered. The finger sensor 5 can adopt a resistive touch switch, a capacitive touch switch, or a mechanical push switch, and preferably adopts a capacitive touch switch. A guide block 6 is fixed on the back side of the finger sleeve 3;

[0036] The driving mechanism includes a lead screw 7 arranged in each finger placement groove and a rotating component 8 for driving the lead screw 7 to rotate. The rotating component 8 adopts a servo motor or a stepper motor, and preferably adopts a servo motor. A vertical plate 26 is erected on the hand placement plate 1. The vertical plate 26 includes a plurality of mounting surfaces perpendicular to each finger placement cavity. The rotating component 8 is arranged on the mounting surface of the vertical plate 26 or the finger placement plate. The lead screw 7 is also perpendicular to the corresponding mounting surface. One end of the lead screw 7 close to the finger root is rotationally assembled on a rotating seat additionally arranged on the finger placement plate through a sleeve or a rotating shaft. The lead screw 7 is arranged along the extending direction of the finger placement groove. The guide block 6 is meshed and matched with the lead screw 7. The lead screw 7 is rotationally assembled in the finger placement groove. When the lead screw 7 rotates, it can drive the guide block 6 to move, that is, drive the finger sleeve 3 to move along the finger extension direction;

[0037] The detection component, the heating head 4, the finger sensor 5, and the rotating component 8 are all electrically connected to the host computer. When the detection component moves with the finger sleeve 3 to the fingertip, it emits a first signal. The host computer calculates the length of the finger according to the first signal and controls the rotating component 8 to continue rotating to move all the finger sleeves 3 to the calculated target position. Then, while starting to time, it controls the heating head 4 to heat up. After receiving the second signal of a certain finger sensor 5, it records the time and records this time as the heat resistance of the finger corresponding to the finger sensor 5. The detection component includes a light source 9 and a photosensitive sensor 10 arranged oppositely. When the detection component detects the length of the finger, the detection component moves in the direction from the finger root to the fingertip. The starting position is close to the palm placement groove. When the detection component moves just beyond the fingertip, the photosensitive receiver that was originally blocked by the finger can receive the light emitted by the light source 9 and emits a first signal. Preferably, the light source 9 adopts colors such as red light, green light, and blue light that are different from natural light and lamp light to prevent the photosensitive sensor 10 from being confused.

[0038] In this embodiment, as Figures 1 to 2As shown, the guide block 6 is provided with a through hole engaged with the screw rod 7, and the finger sleeve 3 cannot be removed from the screw rod 7. When the heat resistance of the finger reaches the limit, the finger can be lifted up or rolled up, and the finger can be detached from the finger sleeve 3 and the finger sensor 5, thereby realizing the recording of the heat resistance time.

[0039] Furthermore, since the finger sleeve 3 is elastic, the finger sleeve 3 needs to be in an open and expanded state at the beginning to reduce contact with the finger, so as to ensure smooth movement of the finger sleeve 3 when measuring the finger length. For this purpose, the detection component also includes a top plate 24 matching the finger sleeve 3, and the two ends of the top plate 24 can be against the top of the finger sleeve 3 to open the finger sleeve 3 to reach a state where the finger can be inserted, such as Figure 6 As shown, the cross-section of the top plate 24 is similar to a "human" shape, and the lower end of the "human" shape is supported on the upper part of the inner walls on both sides of the opening of the upper end of the finger sleeve 3, and a single finger can move freely in the top plate 24 and the opened finger sleeve 3; it should be noted that in this embodiment, the placement and removal of the top rod in the finger sleeve 3 are all performed manually, and the person can be a patient or a medical staff. In order to facilitate the operation of the personnel, a top strip 241 that is easy to hold by hand is provided on the top of the top plate 24, and the top strip 241 forms a convex ridge for easy manual picking.

[0040] Further, such as Figure 2 As shown, the present invention is designed to place the hand on the hand placement board 1 with the palm facing upward. In order to increase the comfort of the patient's hand placement posture, a hand support pad 25 for supporting the back of the hand is provided on the hand placement board 1.

[0041] When using this embodiment, first put the finger into the finger sleeve 3 and then push the top plate 24 against the finger sleeve 3 to open it. Figure 1 As shown, the finger sleeve 3 is placed at the position closest to the finger separation block 2 between the fingers. Since the position of the finger separation block 2 is fixed, the position of the finger detection component is actually known at this time. At this time, the position of the photosensitive sensor 10 is A. At this time, the photosensitive sensor 10 in the detection component cannot receive the light emitted by the light source 9 due to the obstruction of the finger, but the finger sensor 5 can sense the finger at this time; start the rotating component 8, the rotating component 8 drives the screw rod 7 to rotate to move the finger sleeve 3 towards the fingertip, and when it moves to the position just past the fingertip, it reaches the position as shown in the figure. Figure 2When in the position shown, the photosensitive sensor 10 can receive the light emitted by the light source 9 and send out the first signal. Denote the position of the photosensitive sensor 10 at this time as B. The host can obtain the length of the finger in the finger placement cavity by calculating the distance between A and B plus the length of the finger separating block 2 itself, so as to obtain the position of the well point on the finger. Then the host controls the rotating component 8 to rotate to move the finger sleeve 3 to the target position of the heating head. After reaching the position, a warning is issued, and the patient or the staff removes the top plate 24 so that the finger sleeve 3 wraps around the finger to ensure that the heating head 4 is in close contact with the corresponding well point. At the same time, the heating head 4 heats up and the host times. When the patient feels that the well point on the finger reaches the maximum tolerance, bends upward or raises the corresponding finger, the finger disengages from the finger sleeve 3, and the finger sensor 5 sends out a signal indicating that the hand is not sensed. The host records the time at this moment, which is the heat tolerance of the well point on the finger.

[0042] Embodiment 2

[0043] This embodiment is another implementation manner based on Embodiment 1. The description of the same technical solutions as in Embodiment 1 will be omitted, and only the technical solutions different from those in Embodiment 1 will be described.

[0044] Compared with Embodiment 1, in this embodiment, the guiding block 6 can be detached from the lead screw 7, and a pull wire 18 is connected to the finger sleeve 3. By locking the length of the pull wire 18, when the finger moves, the pull wire 18 pulls off the finger sleeve 3 from the finger to realize the timing of the heat tolerance.

[0045] As Figures 3 to 6 shown, a guiding groove 11 is provided at the lower part of the guiding block 6. A notch allowing the lead screw 7 to pass through is provided at the lower part of the guiding groove 11, and the guiding groove 11 meshes with the lead screw 7; the lower end of the guiding groove 11 is in sliding contact with the placement plate 1; As Figure 6 shown, the guiding groove 11 only meshes with the lead screw 7 at an angle of approximately 180°; and due to the self - gravity of the finger sleeve 3 during movement, the support at the bottom of the guiding groove 11 and the limitation of the finger, it is not easy to slip on the lead screw 7.

[0046] Further, as Figure 3 shown, a vertical frame is provided on the hand placement plate 1. Self - winding wire reels 15 corresponding to the positions of each finger placement groove, a pressing block 16 for locking the self - winding wire reels 15, and a pulling through hole 171 penetrating the top plate of the vertical frame are provided on the vertical frame; a coil spring is provided inside the self - winding wire reel 15 to realize automatic wire winding. Specifically, as Figure 3 and Figure 4As shown in the figure, due to the different positions of the thumb and other fingers, the upright frame is divided into a first upright frame 12 and a second upright frame 13. A self - rewinding wire reel 15 corresponding to the thumb is provided on the second upright frame 13 corresponding to the thumb, and the self - rewinding wire reels 15 corresponding to the other four fingers are provided on the top plate of the first upright frame 12; an installation shaft is provided on the upright frame. The self - rewinding wire reel 15 includes a wire reel cylinder. The coil spring is arranged inside the wire reel cylinder or on one side of the cylinder and one end of the coil spring is connected thereto, and the other end of the coil spring is connected to the installation shaft; a pushing member 17 is arranged at intervals on one side of each self - rewinding wire reel 15. The pushing member 17 pushes the pressing block 16 to abut tightly against the self - rewinding wire reel 15. The pressing blocks 16 on the same upright frame can be installed on the same connecting frame 14 and are driven by the same driving member. The pushing member 17 can adopt components such as an electric push rod or a holding electromagnet to ensure that the pressing block 16 can press tightly on the self - rewinding wire reel 15 to stop the rotation of the self - rewinding wire reel 15, thereby locking the extended length of the pulling wire 18; a pulling wire 18 is connected to the self - rewinding wire reel 15. The lower end of the pulling wire 18 passes through the pulling hole 171 and is connected to the finger sleeve 3. Since the finger sleeve 3 cannot pass through the pulling wire 18, the minimum extended length of the pulling wire 18 is limited, and at the same time, it is ensured that the coil spring is always in a tensioned state. However, the coil spring is only for taking up the wire, and the force of the coil spring itself is not enough to pull the finger sleeve 3 off the finger hard.

[0047] In this embodiment, the steps of measuring the length of each finger are similar to those in Embodiment 1, and the process of placing and removing the top mouth plate 24 is also similar, so they will not be described in detail; only the different processes will be described here: In this embodiment, the self - rewinding wire reel 15 is provided to keep the pulling wire 18 in a non - slack state all the time. After measuring the finger length and removing the top mouth plate 24, the finger sleeve 3 is put on the finger, and the finger naturally relaxes into a state of standing upright. The pulling wire 18 is tightened as the finger curls under the pulling force of the self - rewinding wire reel 15. The upright finger is basically directly below the upright frame and is roughly in the Figure 5 state shown in the figure. After the posture of the hand is adjusted, the pushing member 17 pushes the pressing block 16 to abut tightly against the self - rewinding wire reel 15 to restrict its rotation, and fixes the length of the pulling wire 18 exposed outside the upright frame. At this time, the length of the pulling wire 18 extending out of the upright frame is also basically the shortest; when the patient's finger is heated, since the length of the pulling wire 18 has been fixed, the finger can break free from the finger sleeve 3 when the finger bends towards the palm or straightens backward. The finger sensor 5 emits a second signal, enabling the host to record the heat - resistant time of the corresponding finger.

[0048] Compared with Embodiment 1, in this Embodiment 2, when performing the heat - resistance detection, the posture of the patient's hand is more comfortable, and when confirming the end time of heat - resistance, the finger movement is more flexible.

[0049] Embodiment 3

[0050] This embodiment is another implementation based on Embodiment 2. Descriptions of the same technical solutions as in Embodiment 2 will be omitted, and only the technical solutions different from those in Embodiment 2 will be described.

[0051] Compared with Embodiment 2, this embodiment adopts a combined finger sleeve 3, and the finger sleeve 3 can be expanded when measuring the finger length without the top plate 24.

[0052] As Figure 7 shown, the finger sleeve 3 includes a rigid first sub-sleeve 19 and an elastic second sub-sleeve 20. The opposite surfaces of the first sub-sleeve 19 and the second sub-sleeve 20 can be abutted together. The detection component is arranged on the first sub-sleeve 19, and a front block 21 meshingly sleeved on the lead screw 7 is arranged on the bottom surface of the first sub-sleeve 19. The heating head 4 and the finger sensor 5 are arranged on the second sub-sleeve 20, and a guide block 6 with a guide groove 11 is arranged on the second sub-sleeve 20. The lower end of the wire 18 is connected to the second sub-sleeve 20. At least two baffles 27 that can be stuck on the left and right inner sides of the second sub-sleeve 20 are arranged at one end of the first sub-sleeve 19 facing the second sub-sleeve 20, so as to prevent the width of the internal space of the sub-sleeve from becoming wider or smaller; specifically, the second sub-sleeve 20 includes a sleeve base and sleeve side plates connected to the left and right sides of the sleeve base. Elastic strips are arranged on the left and right sides of the sleeve base, so as to be able to give a tendency force for the sleeve side plates hinged or inserted on the left and right inner sides of the sleeve side plates and abutted against the elastic strips on the outside to move inward, so that the bottom side plate can be sleeved on the finger. The wire 18 is connected to the sleeve base; a side gap through which the baffle 27 passes is reserved between the front end of the bottom side plate and the two sides of the sleeve base. Thus, when the finger wearing the finger sleeve 3 bends upward, the baffle 27 can slide down from the inner wall of the bottom side plate, and the bottom side plate without the baffle 27 blocking can be clamped on the finger.

[0053] Furthermore, a positioning hole 22 is arranged at one end of the second sub-sleeve 20 facing the palm placement cavity. A positioning strip 23 that can be inserted into the positioning hole 22 is arranged on the finger separating block 2. The positioning strip 23 and the positioning hole 22 are in clearance fit. The positioning strip 23 is close to the root of the finger. Thus, before measuring the length of the finger, when the finger sleeve 3 is placed on the lead screw 7, the finger sleeve 3 can be inserted on the positioning strip 23 to prevent the finger sleeve 3 from being pulled up by the wire 18 when there is no finger in the finger placement cavity.

[0054] Compared with Embodiment 2, this embodiment does not require the use of the top plate 24. Since the first split sleeve 19 with the length detection component and the baffle 27 cannot be separated from the lead screw 7, while the second split sleeve 20 can be directly separated from the lead screw 7. Therefore, when the second split sleeve 20 is separated from the lead screw 7 by a finger, the baffle 27 can be automatically separated, and the second split sleeve 20 with the heating head 4 can be put on the finger. The upward movement of the second split sleeve 20 can be achieved by the patient or medical staff pulling up the pull wire 18 or increasing the elastic force of the coil spring of the self-winding wire reel 15, so that the coil spring can lift the second split sleeve 20 upward. In this way, when the patient's finger moves upward, the finger sleeve 3 can move upward synchronously along with the patient's finger until the baffle 27 is completely separated from the second split sleeve 20.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
