Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a pulse diagnosis pad that can adapt to different hand shapes. Background Technology

[0002] In traditional Chinese medicine pulse diagnosis, the pulse-taking pad serves as a core tool for supporting the patient's wrist, and its adaptability directly affects the accuracy of the pulse diagnosis and the experience of both the doctor and the patient. Traditional pulse-taking pads have the following prominent problems: Fixed height: Most pulse-taking pads are designed with a fixed height, which cannot adapt to patients of different body types (such as children and adults) or differences in doctor's sitting posture. This results in the patient's arm being suspended in the air, or the doctor bending over or extending their arm, which can easily cause muscle strain and affect the accuracy of pulse perception. Lack of width adjustment: There are significant individual differences in wrist size (e.g., the wrist circumference of children is about 12-15cm, while that of adults can reach 18-22cm). Traditional rigid wrist supports or mechanical structures with adjustable settings cannot achieve stepless width adaptation, often resulting in wrist pressure discomfort or insufficient support. Operational complexity: Some adjustable pulse-taking pads use mechanical structures such as pins and gears. The adjustment process requires manual adjustment of multiple parts, which is cumbersome and has limited accuracy, especially in high-frequency use scenarios in the clinic where efficiency is low. Summary of the Invention

[0003] The main objective of this invention is to provide a pulse diagnosis pad that can adapt to different hand shapes, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A pulse diagnosis pad adaptable to different hand shapes includes a lifting structure, a rotating structure, and a wrist support body. The lifting structure has a lifting structure shell on its surface, a main support column in the middle of the lifting structure shell, and a turbine at the bottom end of the main support column. The upper surface of the main support column has a lifting thread, on which a lifting bolt engages. A support column is located on the upper surface of the lifting bolt, and a bearing plate is located at the top of the support column. The main body of the rotating structure is a rotating lead screw, the rotating lead screw is provided with a rotating thread in the middle, the rotating lead screw is provided with a rotating disk at the top of the rotating lead screw, the bottom end of the rotating lead screw is inserted into a rotating base, and the rotating base is welded to a fixed base. The wrist support body is made of slow rebound memory foam, and the surface of the wrist support body is covered with a highly elastic and highly wear-resistant medical-grade elastic fabric. The wrist support body is fixed to the support plate. The rotating thread and the turbine engage, and the rotation of the turbine drives the main support column and the lifting thread to rotate. The height of the lifting bolt changes due to the rotation of the lifting thread.

[0005] Preferably, the lifting structure housing has an irregular shape inside, and the lifting structure housing restricts the lifting bolt and the lifting thread from rotating together.

[0006] Preferably, a limit plate is provided at the lower end of the lifting thread.

[0007] Preferably, the top of the lifting structure housing has an opening, and the support column passes through the opening at the top of the lifting structure housing.

[0008] Preferably, the bottom surface of the lifting structure housing is provided with bolt holes for fixing, and a rotating shaft is provided at the contact position between the turbine and the inside of the lifting structure housing.

[0009] Preferably, a rotating handle is provided on the surface of the rotating disk.

[0010] Preferably, the fixed chassis has threaded holes at its four corners for connection and fixation.

[0011] Compared with the prior art, the present invention has the following beneficial effects. This invention utilizes the principle of a screw jack, where a screw drives a worm gear to adjust the height of the pulse diagnosis pad. The rotational motion drives the meshing worm gear (or nut) to move linearly along the axial direction, thus raising or lowering the pulse diagnosis pad. The screw drive offers high transmission precision, ensuring precise adjustment of the pulse diagnosis pad height to accommodate different patient arm lengths and physician pulse-taking habits. The screw drive also features a self-locking function when stationary, maintaining a stable pulse diagnosis pad height without the need for additional braking devices. This prevents height deviations caused by patient movement or equipment vibration, ensuring accurate pressure sensing during pulse diagnosis.

[0012] This invention provides adaptive, stepless width adjustment with an extremely simplified structure: a one-piece wrist rest body is constructed from a composite of slow-rebound memory foam and highly elastic, wear-resistant medical-grade elastic fabric. The elastic deformation of the materials themselves replaces complex mechanical telescopic sliders, guide rails, and locking mechanisms. This design allows the wrist rest to automatically adapt to the wrist size of different patients, achieving true stepless adjustment. Attached Figure Description

[0017] Example Please see Figure 1-5 The present invention provides a technical solution: This invention discloses a pulse diagnosis pad adaptable to different hand shapes, comprising a lifting structure 1, a rotating structure 2, and a wrist support body 3. The lifting structure 1 has a lifting structure outer shell 101 on its surface, and a main support column 108 is disposed in the middle of the lifting structure outer shell 101. A turbine 104 is disposed at the bottom end of the main support column 108. The upper surface of the main support column 108 has a lifting thread 106, on which a lifting bolt 105 engages. A support column 102 is disposed on the upper surface of the lifting bolt 105, and a bearing plate 103 is disposed at the top end of the support column 102. The main body of the rotating structure 2 is a rotating screw 201. A rotating thread 202 is provided in the middle of the rotating screw 201. A rotating disk 203 is provided at the top of the rotating screw 201. The bottom end of the rotating screw 201 is inserted into the rotating base 204. The rotating base 204 is welded to the fixed base 205. The wrist support body 3 is made of slow rebound memory foam, and the surface of the wrist support body 3 is covered with a highly elastic and highly wear-resistant medical-grade elastic fabric. The wrist support body 3 is fixed to the support plate 103. The interior is made of medium-density slow-rebound memory foam, with a curved surface sculpted on top to conform to the physiological curve of the wrist, providing stable and comfortable support. Function: To maintain the basic shape and support strength of the wrist rest, preventing excessive sagging during use.

[0018] An external, highly elastic, and abrasion-resistant medical-grade elastic fabric (such as high-elastic spandex or medical-grade silicone) forms a complete sleeve, tightly wrapping around the inner core support layer. The left and right sides of this elastic sleeve are not fixedly connected, but rather form two natural, flexible wings. When a wider wrist needs to be supported, these flexible wings naturally stretch outwards under the lateral pressure of the wrist (the expansion range can be controlled within ±3cm through the material's elastic design). When the wrist is removed, the material's elastic recovery force automatically pulls them back to their initial state. The rotating thread 202 and the turbine 104 mesh, and the rotation of the turbine 104 drives the main support column 108 and the lifting thread 106 to rotate. The height of the lifting bolt 105 changes due to the rotation of the lifting thread 106.

[0019] In this embodiment, the lifting structure housing 101 has an irregular internal structure, and the lifting structure housing 101 restricts the lifting bolt 105 and the lifting thread 106 from rotating together.

[0020] In this embodiment, a limiting plate 107 is provided at the lower end of the lifting thread 106.

[0021] In this embodiment, the top of the lifting structure housing 101 has an opening, and the support column 102 passes through the opening at the top of the lifting structure housing 101.

[0022] In this embodiment, bolt holes are provided on the bottom surface of the lifting structure housing 1 for fixing, and a rotating shaft is provided at the contact position between the turbine 104 and the inside of the lifting structure housing 1.

[0023] In this embodiment, a rotating handle is provided on the surface of the rotating disk 203.

[0024] In this embodiment, the fixed base 205 is provided with threaded holes at its four corners for connection and fixation.

[0025] Specific implementation process I. Overall Operation Process The patient or doctor manually adjusts the height of the pulse diagnosis pad by rotating structure 2, driving the lifting structure 1. The wrist support body 3 automatically adapts to the wrist size through material elasticity, completing the pulse diagnosis preparation in both height and width dimensions. This is specifically divided into three stages: II. Height Adjustment Logic of Lifting Structure 1 Initial state: The lifting bolt 105 engages with the main support column 108 through the lifting thread 106. At this time, the support column 102 is in the lowest position, and the bearing plate 103 is flush with the top surface of the lifting structure shell 101.

[0026] The limiting plate 107 is located at the lower end of the lifting thread 106 to prevent the lifting bolt 105 from falling off due to excessive downward movement.

[0027] Height adjustment process: Manual drive: Rotate the handle on the rotating disk 203 to drive the rotating screw 201 to rotate. Since the rotating thread 202 meshes with the turbine 104, the rotational motion of the rotating screw 201 is converted into the rotation of the turbine 104.

[0028] Screw drive: When the worm gear 104 rotates, it drives the main support column 108 to rotate synchronously. The lifting thread 106 on the surface of the main support column 108 rotates accordingly, driving the lifting bolt 105 to move axially along the lifting thread 106.

[0029] Lifting guide: The irregularly shaped inner cavity of the lifting structure housing 101 restricts the rotational freedom of the lifting bolt 105, allowing it to move only in a linear motion along the axial direction. The support column 102 rises and falls synchronously with the lifting bolt 105, ultimately driving the bearing plate 103 and the wrist support body 3 to adjust to the target height.

[0030] Self-locking fixation: After rotation stops, the self-locking characteristic of the screw drive system keeps the lifting bolt 105 in its current position, providing stable support for the pulse pad without the need for an additional braking device.

[0031] Limit protection: When the lifting bolt 105 rises to the highest point, its top contacts the inner wall of the hole at the top of the lifting structure housing 101 to prevent excessive rise and dislodging of the structure; when it falls to the lowest point, the limit plate 107 contacts the bottom surface of the lifting structure housing 101 to prevent the lifting bolt 105 from colliding with the turbine 104.

[0032] III. Rotational Fixing Logic of Rotational Structure 2 Rotation drive: The rotating disk 203 forms a rotating pair with the rotating base 204 via the rotating screw 201. The rotating base 204 is welded to the fixed chassis 205 to ensure the stability of the overall structure.

[0033] The rotating handle on the surface of the rotating disc 203 provides a lever effect, reducing the force required for rotation, making it especially suitable for medical staff with less strength or elderly patients.

[0034] Fixing and positioning: The threaded holes at the four corners of the fixed base 205 are fixed to the examination table or the ground by bolts to ensure that the rotating structure 2 does not shift during the adjustment process.

[0035] The rotation angle of the lead screw 201 can be visually adjusted through the scale markings on the rotating disk 203 (such as each division corresponding to a 5mm height change), thus improving operational accuracy.

[0036] IV. Adaptive Width Adjustment Logic of Wrist Support Body 3 Material properties drive the process: Slow-rebound memory foam serves as the inner core of the wrist support body 3. Under the pressure of the patient's wrist, it undergoes elastic deformation, automatically conforming to the contour of the wrist and forming a concave curved surface that matches the hand shape.

[0037] Medical-grade elastic fabric wraps around the memory foam surface, providing high elasticity and abrasion resistance, ensuring that it will not break or loosen during repeated deformation, while maintaining a smooth surface and reducing frictional resistance during pulse diagnosis.

[0038] Stepless width adaptation: When wrists vary in size, the slow rebound properties of memory foam allow it to slowly return to its original shape after pressure is released, adapting to the pressure distribution of different hand shapes the next time. The stretchability of the elastic fabric allows the wrist support body 3 to expand steplessly in the horizontal direction, covering a range of wrist sizes from children to adults.

[0039] The wrist support body 3 is rigidly connected to the lifting structure 1 through the bearing plate 103, ensuring that the width adaptation function is not affected when the height is adjusted, and realizing the decoupled adjustment of "height-width".

[0040] Post-treatment repositioning stage: Rotate the rotating disk 203 in the opposite direction, and the lifting bolt 105 descends to the lowest position along the lifting thread 106. The wrist support body 3 returns to its initial shape, ready for the next patient to use.

[0041] This invention achieves stepless height adjustment through a screw-turbine transmission and achieves width self-adaptation by combining the material properties of slow-rebound memory foam and elastic fabric, forming a dual technical solution of "precision mechanical transmission + intelligent material adaptation", which significantly improves the clinical applicability and patient comfort of pulse diagnosis pads.
