Description

Technical Field

[0001] The present invention relates to the technical field of medical diagnosis, and in particular to a tactile perception diagnosis device. Background Art

[0002] The tactile perception diagnostic device is a special device used in the medical field to evaluate the patient's tactile function. It stimulates the skin surface through acupuncture to detect the patient's tactile perception ability. In the field of neurology, it helps doctors more accurately evaluate and diagnose patients' tactile dysfunction.

[0003] Traditional tactile examination methods usually require medical staff to hold a stick or other simple instruments to lightly touch or slide the patient's arm to observe the patient's reaction to determine the degree of tactile perception disorder. This method has many limitations. First, since tactile perception examinations usually require testing of multiple parts of the arm to ensure the accuracy of the results, and conventional equipment cannot fully examine the patient's arm, medical staff need to spend a long time on each patient, which undoubtedly increases the workload in a busy hospital environment. Second, since this examination method relies on the subjective judgment of medical staff and lacks unified standards and quantity, it is difficult to obtain accurate results. At the same time, different medical staff will have different operating strengths and skills, making it difficult for them to maintain the constancy and consistency of stimulation. Even if they perform multiple examinations on the same patient, they may easily get different results. This repeatability problem may easily cause medical staff to track the patient's tactile changes, which will affect the reliability of the examination results. In addition, the patient's age, gender, and tactile response also vary, which will lead to deviations in the diagnostic results. Excessive force may cause pain or discomfort to the patient, or too little force may fail to cause an effective tactile response, which may easily lead to misdiagnosis or missed diagnosis.

[0004] To this end, a tactile perception diagnostic device is proposed, which can provide a comprehensive diagnosis and assist medical staff in controlling the strength to avoid misdiagnosis. Summary of the invention

[0005] The purpose of the present invention is to provide a tactile perception diagnosis device to solve the problem of diagnostic errors caused by difficulty in accurately controlling the force.

[0006] The technical solution of the present invention is: a tactile perception diagnostic device, including a mounting shell, an inner cylinder arranged inside the mounting shell, a soft pad arranged inside the inner cylinder, an I-shaped diagnostic part slidably connected inside the mounting shell, a transmission part rotatably connected inside the mounting shell, a pressure member and a reinforcement limit member arranged inside the mounting shell, a support member connected inside the mounting shell, and an indicator member slidably connected to the reinforcement limit member, wherein the transmission member includes a claw wheel and a spur gear rotatably connected inside the mounting shell, a bearing is fixedly connected between the claw wheel and the spur gear, and the pressure member and the reinforcement limit member are connected to the mounting shell. Located on one side of the claw wheel, the pressure piece is parallel to the reinforcement limit piece, and the spur gear is meshed with one side of the I-shaped diagnostic piece. The reinforcement limit piece limits the rotation of the claw wheel when it is in contact with the claw wheel, and reaches the reinforcement position after the reinforcement limit piece is separated from the claw wheel. When the reinforcement limit piece is in contact with the claw wheel, one end of the indicator piece is in contact with the I-shaped diagnostic piece. When the pressure piece drives the claw wheel and the spur gear to rotate, the I-shaped diagnostic piece drives the indicator piece to move downward synchronously, and at the same time, the reinforcement limit piece is separated from the claw wheel when it gradually moves to the reinforcement position, and the reinforcement limit piece fixes the indicator piece when it is in the reinforcement position.

[0007] Furthermore, the mounting shell includes a sleeve shell, a plurality of vertical shafts disposed and located inside the sleeve shell, a first spring located outside the vertical shaft and connected between the sleeve shell and the I-shaped diagnostic member, a support block, a support frame and a support shaft disposed inside the sleeve shell, a strip groove opened on the sleeve shell, and a mark disposed on one side of the sleeve shell, a button is slidably connected to one side of the outer side of the sleeve shell, one side of the button extends to the interior of the sleeve shell and is connected to the pressure member, and the mark is located near the strip groove.

[0008] Furthermore, the pressure-applying member includes a bar shaft having one end connected to the button, a second spring located outside the bar shaft and connected between the support block and the button, a bottom block connected to the other end of the bar shaft, an inclined block arranged on the side of the bottom block away from the claw wheel, and a spring sheet rotatably connected to the bottom of the bottom block, a convex strip being arranged on the other side of the bottom block, and the spring sheet does not contact the claw wheel when the second spring is not deformed.

[0009] Furthermore, the indicator part includes a slot block slidably connected to the reinforcement limit part, a strip piece connected to one end of the slot block close to the I-shaped diagnostic part, and an indicator mark connected to the other end of the slot block. When the reinforcement limit part is in contact with the claw wheel, the strip piece is in contact with the I-shaped diagnostic part, and one end of the indicator mark passes through the strip slot.

[0010] Furthermore, the reinforcement limit member includes a blocking member located inside the mounting shell, a connecting frame fixedly connected to one side of the blocking member, a square rod fixedly connected to one side of the connecting frame, a pull ring strip fixedly connected to the top of the connecting frame, and a third spring located outside the support shaft and connected between the sleeve and the square rod.

[0011] One end of the pull ring strip is located outside the shell, two support shafts and three springs are provided, the upper and lower ends of the square rod are slidably connected to the corresponding support shafts, the notch block is slidably connected to the outside of the square rod, and the length of the inner groove of the notch block is greater than the length of the square rod.

[0012] Furthermore, the blocking member includes a connecting block fixedly connected to the connecting frame, a first magnetic block fixedly connected to one side of the connecting block, a block-shaped claw rotatably connected to the other side of the connecting block, and a torsion spring connected between the connecting block and the block-shaped claw. A convex strip is provided on the top of the connecting block close to the block-shaped claw, and the width of the block-shaped claw plus the spring sheet is smaller than the width of the claw wheel.

[0013] Furthermore, a second magnetic block is arranged inside the mounting shell, and the second magnetic block is the same size as the first magnetic block, and the second magnetic block is located on one side of the first magnetic block. When the block-shaped claw contacts the claw wheel, it limits the rotation of the claw wheel. When the first magnetic block and the second magnetic block are adsorbed, the connecting block is located in the reinforcement position, and when the support shaft is not deformed, one side of the square rod is fitted with the inner wall of one side of the slot block, and the distance from the first magnetic block to the second magnetic block is greater than the distance from the other side of the square rod to the inner wall of the other side of the indicator mark.

[0014] Furthermore, the four fixed points of the I-shaped diagnostic part are all slidably connected to the vertical axis, the middle part of the I-shaped diagnostic part is a needle, the position of the I-shaped diagnostic part located above the strip piece is a convex piece, the side of the I-shaped diagnostic part close to the spur gear is a rack, the rack is meshed with the spur gear, and when the convex piece is in contact with the strip piece, the connecting block is in a check position.

[0015] Furthermore, the support member includes a guide rod connected between one side of the support frame and the sleeve shell, and a fourth spring located outside the guide rod and connected between the strip piece and the support frame, and the strip piece is slidably connected to the outside of the guide rod.

[0016] Furthermore, two first springs are symmetrically arranged about the central axis of the inner cylinder, an I-shaped notch is opened on the inner cylinder, and the I-shaped diagnostic component is located directly above the I-shaped notch.

[0017] Beneficial effects of the present invention:

[0018] 1. By pressing the pressure piece, the transmission is transmitted to the claw wheel and the spur gear, so that the spur gear drives the I-shaped diagnostic piece to move downward step by step, so as to contact the patient for detection. Pressing can provide uniform and stable force, avoiding diagnostic errors caused by direct pressure and uneven force. At the same time, due to the consistency and controllability of the force, the pain and discomfort felt by the patient can be reduced, ensuring that the overall examination experience is more comfortable and speeding up the measurement progress. At the same time, when the I-shaped diagnostic piece descends, it cooperates with the index piece, so that the index piece moves downward synchronously, and the reinforced limit piece can fix the index piece when the claw wheel restriction is released, so that the position index of the index piece can be checked, so that medical staff can accurately judge whether the detection index meets the predetermined standard range, thereby improving the efficiency of the diagnostic process.

[0019] 2. Standardized testing can be achieved by coordinating the indicator parts with the markings. The pressure parts can be controlled by pressing the buttons and finally the position of the indicator parts can be observed, which makes the operation easy and reduces the difficulty of operation for medical staff. Regardless of the experience of the medical staff, the consistency of operation can be maintained. When targeting different populations, the position of the indicator parts can be used to ensure that accurate diagnosis results can be achieved even if the patients are different. At the same time, the diagnosis results can be recorded to help review and subsequent comparison.

[0020] 3. The two control parts, buttons and pull rings, can reduce the possibility of errors during operation and avoid diagnostic errors caused by operational errors. At the same time, after the patient responds, the pull ring can be used to quickly separate the I-shaped diagnostic piece from the patient to prevent the I-shaped diagnostic piece from causing harm to the patient, and the indicator mark can be directly fixed. One of the two control parts is used to control the descent of the I-shaped diagnostic piece for diagnosis, and the other is used to confirm the data and move the I-shaped diagnostic piece back. The usage is intuitive and easy to understand, allowing medical staff to easily understand the function of each control and making the equipment more integrated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1-9, which is the first embodiment of the present invention, provides a tactile perception diagnostic device, including a mounting shell 1, an inner cylinder 2 arranged inside the mounting shell 1, a soft pad 3 arranged inside the inner cylinder 2, an I-shaped diagnostic part 4 slidably connected to the mounting shell 1, a transmission part 5 rotatably connected to the mounting shell 1, a pressure member 6 and a reinforcement limit member 7 arranged inside the mounting shell 1, a support member 8 connected to the mounting shell 1, and an indicator member 9 slidably connected to the reinforcement limit member 7. The transmission member 5 includes a claw wheel 51 and a spur gear 52 rotatably connected to the inside of the mounting shell 1, the claw wheel 51 and the spur gear 52 are fixedly connected by a bearing, and are connected by a bearing by conventional means. The pressure member 6 and the reinforcement limit member 7 are located on one side of the claw wheel 51, the pressure member 6 is parallel to the reinforcement limit member 7, the spur gear 52 is meshed with one side of the I-shaped diagnostic part 4, and the reinforcement limit member 7 is meshed with the claw wheel 51. When in contact, the claw wheel 51 is restricted from rotating, and the reinforcement limit member 7 separates from the claw wheel 51 and reaches the reinforcement position. When the reinforcement limit member 7 is in contact with the claw wheel 51, one end of the indicator member 9 is in contact with the I-shaped diagnostic member 4. When the pressure member 6 drives the claw wheel 51 and the spur gear 52 to rotate, the I-shaped diagnostic member 4 drives the indicator member 9 to move downward synchronously. At the same time, the reinforcement limit member 7 gradually moves to the reinforcement position and separates from the claw wheel 51. When the reinforcement limit member 7 is in the reinforcement position, the indicator member 9 is fixed, so that the examination can be completed more quickly, reducing the patient's waiting time. At the same time, the I-shaped diagnostic member 4 is gradually moved downward to realize diagnosis, and the force is controllable to provide uniform and stable force, thereby avoiding diagnostic errors caused by uneven force of manual operation. At the same time, since the entire device is placed on the platform, medical staff and patients can operate in a more comfortable position during diagnosis, reducing the need for inappropriate postures.

[0034] Reference Figure 1-5 The mounting shell 1 includes a shell 101, a plurality of vertical shafts 102 disposed inside the shell 101, a first spring 103 disposed outside the vertical shaft 102 and connected between the shell 101 and the I-shaped diagnostic member 4, a support block 104, a support frame 105 and a support shaft 106 disposed inside the shell 101, a strip groove 107 provided on the shell 101, and a mark 108 provided on one side of the shell 101, a button 10 is slidably connected to one side of the outer side of the shell 101, one side of the button 10 extends to the interior of the shell 101 and is connected to the pressure member 6, a conventional sliding groove and a mounting groove are provided on the surface of the shell 101, which are conventional means to enable the button 10 to slide in the shell 101, the mark 108 is located near the strip groove 107, and the support frame 105 and the support shaft 106 are conventional supporting and mounting structures.

[0035] Reference Figure 2-5The pressure member 6 includes a bar shaft 61 connected to the button 10 at one end, a second spring 62 located outside the bar shaft 61 and connected between the support block 104 and the button 10, a bottom block 63 connected to the other end of the bar shaft 61, an inclined block 64 arranged on the side of the bottom block 63 away from the claw wheel 51, and a spring sheet 65 rotatably connected to the bottom of the bottom block 63. A convex strip is arranged on the other side of the bottom block 63, so that the spring sheet 65 can only rotate in one direction. When the second spring 62 is not deformed, the spring sheet 65 does not contact the claw wheel 51, thereby avoiding the spring sheet 65 from blocking the claw wheel 51. The button 10 can directly receive the pressing force, which is then transmitted to the claw wheel 51. Due to the pressing transmission, the force control is accurate, which can avoid causing excessive pain or discomfort to the patient.

[0036] Reference Figure 2-6 The indicator member 9 includes a slot block 91 slidably connected to the reinforcement limit member 7, a strip piece 92 connected to one end of the slot block 91 near the I-shaped diagnostic member 4, and an indicator mark 93 connected to the other end of the slot block 91. When the reinforcement limit member 7 is in contact with the claw wheel 51, the strip piece 92 is in contact with the I-shaped diagnostic member 4. When the reinforcement limit member 7 is not in contact with the claw wheel 51, the strip piece 92 will also be separated from the I-shaped diagnostic member 4, so that the I-shaped diagnostic member 4 is quickly separated from the patient to avoid compression and injury to the patient. One end of the indicator mark 93 passes through the strip slot 107, providing accurate, objective and standardized test results, which can improve the quality of diagnosis.

[0037] Specifically, when using it, it is necessary to test a plurality of different groups of people, so as to record the average value of the position of the mark 108 indicated by the indicator 93 after diagnosis for people of different ages and genders. Then, based on this average value as a reference, standardization can be achieved, so that this value can be used as a reference when diagnosing other patients.

[0038] Reference Figure 2-6 The reinforcement limit member 7 includes a blocking member 71 located inside the mounting shell 1, a connecting frame 72 fixedly connected to one side of the blocking member 71, a square rod 73 fixedly connected to one side of the connecting frame 72, a pull ring strip 74 fixedly connected to the top of the connecting frame 72, and a third spring 75 located outside the support shaft 106 and connected between the sleeve shell 101 and the square rod 73.

[0039] One end of the pull ring strip 74 is located outside the shell 101, and two support shafts 106 and third springs 75 are each provided. The upper and lower ends of the square rod 73 are slidably connected to the corresponding support shafts 106, so that the upper and lower ends of the square rod 73 are supported and restricted by the support shafts 106, while ensuring the overall stability of the reinforcement limit member 7. The notch block 91 is slidably connected to the outside of the square rod 73, and the notch block 91 and the barrier member 71 fit together and limit each other. The notch block 91 can move vertically, and the length of the inner groove of the notch block 91 is greater than the length of the square rod 73, so that the square rod 73 can move inside the notch block 91. In addition, the button 10 is used to control the pressure member 6 as a whole to realize the downward movement of the I-shaped diagnostic member 4, and pulling the pull ring strip 74 directly realizes the return of the I-shaped diagnostic member 4 and the fixation of the indicator member 9 as a whole, so that medical staff only need to remember two steps, which helps to maintain the consistency of the diagnosis results.

[0040] Reference Figure 2-6 The blocking member 71 includes a connecting block 711 fixedly connected to the connecting frame 72, a first magnetic block 712 fixedly connected to one side of the connecting block 711, a block-shaped claw 713 rotatably connected to the other side of the connecting block 711, and a torsion spring 714 connected between the connecting block 711 and the block-shaped claw 713. A convex strip is provided on the top of the connecting block 711 near the block-shaped claw 713, and the convex strip has the same function as one side of the bottom block 63, so that the block-shaped claw 713 is restricted to only rotate in one direction. The block-shaped claw 713 and the spring sheet 65 are within the thickness of the claw wheel 51. In order to prevent the two from colliding, the width of the block-shaped claw 713 plus the spring sheet 65 is made smaller than the width of the claw wheel 51, so as to achieve accurate and stable transmission and ensure that each patient can receive proper examination.

[0041] Reference Figure 2-7 A second magnetic block 11 is disposed inside the mounting shell 1. The second magnetic block 11 is the same size as the first magnetic block 712. The second magnetic block 11 is located on one side of the first magnetic block 712. When the block-shaped claw 713 contacts the claw wheel 51, the claw wheel 51 is restricted from rotating, thereby realizing the one-way rotation of the claw wheel 51, which is similar to a ratchet blocking structure. When the first magnetic block 712 and the second magnetic block 11 are adsorbed, the connecting block 711 is located in a reinforcement position. When the support shaft 106 is not deformed, one side of the square rod 73 is in contact with the inner wall of one side of the notch block 91, and the distance from the first magnetic block 712 to the second magnetic block 11 is greater than the distance from the square rod 73 to the second magnetic block 11. The distance from the other side to the inner wall of the other side of the indicator 93, if the pull ring strip 74 is pulled to make the square rod 73 slide, the support shaft 106 will be compressed, the first magnetic block 712 will be close to the second magnetic block 11, and the distance from the other side of the square rod 73 to the inner wall of the other side of the indicator 93 will also be shortened. When the first magnetic block 712 and the second magnetic block 11 are adsorbed, since the distance between the square rod 73 and the slot block 91 is already smaller than the distance between the first magnetic block 712 and the second magnetic block 11, the square rod 73 has squeezed the slot block 91, so that the slot block 91 is fixed. In addition, the difference between the two spacings is small.

[0042] Reference Figure 1-9 The four fixed points of the I-shaped diagnostic member 4 are all slidably connected to the vertical shaft 102. The middle part of the I-shaped diagnostic member 4 is the needle 41. The position of the I-shaped diagnostic member 4 above the strip piece 92 is the convex piece 42. The side of the I-shaped diagnostic member 4 close to the spur gear 52 is the rack 43. The rack 43 is meshed with the spur gear 52. When the convex piece 42 is fitted with the strip piece 92, the connecting block 711 is in the non-return position, that is, the connecting block 711 is in the non-return position, the square rod 73 will not fix the notch block 91, and the block claw 713 will restrict the claw wheel 51, making it impossible for the I-shaped diagnostic part 4 to move back. At this time, the protruding piece 42 will fit with the strip piece 92, so when the I-shaped diagnostic part 4 moves down, it will drive the indicator part 9 to move down as a whole. Among them, the transmission ratio of the rack 43, the claw wheel 51 and the spur gear 52 can be one to one. When the claw wheel 51 rotates, the spur gear 52 rotates synchronously, and the spur gear 52 will drive the rack 43. The angle of a single rotation of the claw wheel 51 represents the descending distance of the I-shaped diagnostic part 4.

[0043] Reference Figure 1-9 The support member 8 includes a guide rod 81 connected between one side of the support frame 105 and the housing 101, and a fourth spring 82 located on the outside of the guide rod 81 and connected between the strip piece 92 and the support frame 105. The strip piece 92 is slidably connected to the outside of the guide rod 81. A protrusion is provided on one side of the support frame 105 to support the guide rod 81. The guide rod 81 passes through the through hole in the middle of the strip piece 92, so that the guide rod 81 limits the strip piece 92, that is, the notch block 91 is limited by the square rod 73, the strip piece 92 is limited by the guide rod 81, and the indicator mark 93 is limited by the strip notch 107, thereby ensuring the overall stability of the indicator member 9, and the restrictions of the three will not affect the overall vertical movement of the indicator member 9.

[0044] Reference Figure 2-9 Two first springs 103 are symmetrically arranged about the central axis of the inner cylinder 2, so that the first springs 103 can support both sides of the I-shaped diagnostic piece 4 after being compressed. An I-shaped slot 21 is opened on the inner cylinder 2, and the I-shaped diagnostic piece 4 is located directly above the I-shaped slot 21. The shape of the I-shaped slot 21 is similar to that of the I-shaped diagnostic piece 4. The I-shaped diagnostic piece 4 can pass through the I-shaped slot 21 to contact the patient.

[0045] The working principle of the present invention is as follows: when the patient puts his arm into the inner tube 2, the doctor moves the button 10 downward, so that the bar shaft 61 moves downward, and the button 10 compresses the second spring 62. When the bar shaft 61 moves downward, it drives the bottom block 63, the inclined block 64 and the spring sheet 65 to move downward. When the spring sheet 65 moves downward, the claw wheel 51 is driven, so that the outer claw of the claw wheel 51 is squeezed, and the claw wheel 51 then rotates. The claw wheel 51 will drive the spur gear 52 to rotate synchronously. The spur gear 52 passes through the rack 43 on the outer side of the I-shaped diagnostic part 4, so that the I-shaped diagnostic part 4 moves downward. When the I-shaped diagnostic part 4 moves downward, it is restricted by the vertical axis 102 to move vertically downward. At the same time, when the I-shaped diagnostic part 4 moves downward, the first spring 103 is compressed. At the same time, the I-shaped diagnostic part 4 moves downward. When the strip piece 92 moves downward, the convex piece 42 on one side will squeeze the strip piece 92, so that the strip piece 92 moves downward, and when the strip piece 92 moves downward, it drives the indicator mark 93 and the notch block 91 to move downward synchronously, and the downward movement of the strip piece 92 is limited by the guide rod 81 and moves downward vertically, and when the strip piece 92 moves downward, it compresses the fourth spring 82, and the notch block 91 slides outside the square rod 73, and the indicator mark 93 is limited by the strip notch 107 to slide synchronously, and each time the claw wheel 51 rotates, it squeezes the block claw 713 once, so that the block claw 713 rotates and the torsion spring 714 is twisted, and after the block claw 713 loses the squeezing, the torsion spring 714 drives the block claw 713 to rotate, forming a non-return structure, so that the claw wheel 51 cannot rotate, and the I-shaped diagnostic part 4 cannot When the spring sheet 65 moves up to reset, and when the button 10 is repeatedly pressed, when the spring sheet 65 squeezes the outer claw of the claw wheel 51, since the spring sheet 65 contacts the claw wheel 51 and the claw wheel 51 rotates, the spring sheet 65 will be squeezed by the next outer claw of the claw wheel 51 when it moves up, and the spring sheet 65 will rotate in the direction of the inclined block 64, and the spring sheet 65 will squeeze the inclined block 64. When the spring sheet 65 is not in contact with the claw wheel 51, the inclined block 64 will rebound quickly to reset the spring sheet 65. After repeatedly pressing the button 10 through the transmission, the I-shaped diagnostic part 4 continuously drives the indicator part 9 to move downward as a whole, and the I-shaped diagnostic part 4 will pass through the I-shaped notch 21 into the interior of the inner tube 2. The position of the needle 41 of the I-shaped diagnostic part 4 will contact the patient's arm. After the patient responds, the pull ring strip is quickly pulled 74, the pull ring strip 74 drives the barrier member 71 as a whole, the connecting frame 72 and the square rod 73 to move synchronously, and the square rod 73 is restricted by the two supporting shafts 106, so that the reinforcement limit member 7 moves horizontally as a whole, and the square rod 73 compresses the third spring 75 when moving, and at the same time, the block claw 713 will be separated from the claw wheel 51 after being driven, and with rapid pulling, the first magnetic block 712 will be adsorbed and fixed by the second magnetic block 11, and the square rod 73 will squeeze and reinforce the inside of the notch block 91, so that the indicator member 9 is in a fixed state as a whole. At this time, the claw wheel 51 loses the non-return resistance, and the compressed vertical shaft 102 rebounds to make the I-shaped diagnostic member 4 move up. When the I-shaped diagnostic member 4 moves up, the rack 43 is used to make the spur gear 52 and the claw wheel 51 rotate synchronously and quickly.The claw wheel 51, the spur gear 52 and the I-shaped diagnostic part 4 are reset, and the indicator mark 93 is fixed by the square rod 73 at this time. The diagnosis can be completed by observing the mark 108 indicated by the indicator mark 93. At this time, the pull ring strip 74 is pushed, the first magnetic block 712 will separate from the second magnetic block 11, and the support shaft 106 rebounds to reset the reinforcement limiter 7 as a whole. The notch block 91 loses the restriction of the square rod 73, and the fourth spring 82 rebounds to make the strip piece 92 fit with the I-shaped diagnostic part 4 again. The notch block 91 and the strip piece 92 are also reset synchronously, and the block claw 713 will fit with the claw wheel 51 again, so that the claw wheel 51 is restricted, and the button 10 can be pressed next time.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
