Description

Technical Field

[0001] This application relates to the field of upper limb tremor stimulator testing technology, and in particular to a tooling for testing upper limb tremor stimulators. Background Technology

[0002] The upper limb tremor stimulator is a wearable medical device that targets and stimulates the central nervous system motor circuit in the thalamus via peripheral nerves. It is used as an adjunct therapy for patients with upper limb neuromuscular injuries by stimulating nerve and muscle tissue. In clinical application, this product has shown a positive adjunctive therapeutic effect on upper limb tremors caused by essential tremor (ET) and some cases of Parkinson's disease (PD). The upper limb tremor stimulator is typically worn on the wrist. The device consists of a main unit and a strap, both equipped with electrodes that provide electrical stimulation to the peripheral nerves of the wrist.

[0003] Upper limb tremor stimulators must undergo testing before leaving the factory. This includes testing the electrical signals output by the stimulator and analyzing whether parameters such as voltage and current meet standards. Existing testing devices are relatively fragmented, with poor overall integration and inconvenient operation. The preparation process before testing is time-consuming, and poor contact between probes and electrodes is prone to occur. Utility Model Content

[0004] To address the aforementioned problems, this application provides a tooling for testing an upper limb tremor stimulator. This tooling is ingeniously designed and has a simple structure. It boasts high integration, is easy to operate, and significantly reduces preparation time while ensuring good contact between the probe and the electrode. The technical solution adopted in this application is as follows:

[0005] A fixture for testing an upper limb tremor stimulator includes a first mounting plate and a second mounting plate, which are arranged adjacent to each other. The first mounting plate has a strap clamping station, and the second mounting plate has a dial clamping station. The strap clamping station has a strap clamping assembly, which includes a first gripper and a first probe. Both the first probe and the first gripper are mounted on the first mounting plate, with the first gripper located on one side of the first probe. The first gripper can press down on the stimulator's strap to make the first probe contact an electrode on the stimulator's strap. The dial clamping station has a dial clamping assembly, which includes a second gripper and a second probe. Both the second probe and the second gripper are mounted on the second mounting plate, with the second gripper located on one side of the second probe. The second gripper can press down on the stimulator's dial to make the second probe contact an electrode on the stimulator's dial.

[0006] In some implementations, the position of the first probe on the first mounting plate is movable, and the position of the second probe on the second mounting plate is movable.

[0007] In some embodiments, the first mounting plate has a first strip-shaped hole, and a first rack portion is provided on each of the opposite sides of the first strip-shaped hole. The first probe is mounted on a first movable block, and the bottom of the first movable block is provided with a first engaging portion adapted to the first rack portion. The first rack portion is engaged with the first engaging portion, and the first strip-shaped hole is used to allow space for the movement of the first probe. The second mounting plate has a second strip-shaped hole, and a second rack portion is provided on each of the opposite sides of the second strip-shaped hole. The second probe is mounted on a second movable block, and the bottom of the second movable block is provided with a second engaging portion adapted to the second rack portion. The second rack portion is engaged with the second engaging portion, and the second strip-shaped hole is used to allow space for the movement of the second probe.

[0008] In some embodiments, the first rack portion has a first abutting surface on the side away from the first strip-shaped hole, and the two ends of the first moving block abut against the corresponding first abutting surface; the second rack portion has a second abutting surface on the side away from the second strip-shaped hole, and the two ends of the second moving block abut against the corresponding second abutting surface.

[0009] In some embodiments, the enclosure also includes a rectangular box, the top surface of which is the first mounting plate and the side surface of which is the second mounting plate.

[0010] In some embodiments, the first mounting plate is provided with a first screw hole, and a screw is screwed into the first screw hole to fix one end of the stimulator strap.

[0011] In some embodiments, the housing includes two opposing third mounting plates, which are perpendicular to the first mounting plate and the second mounting plate, respectively, and the third mounting plates are provided with handles.

[0012] In some embodiments, the pressing end of the first gripper is fitted with a pad that can cover the electrodes on the stimulator strap so that the first probe is in close contact with the electrodes on the stimulator strap.

[0013] In some embodiments, the first movable block and the first rack portion are magnetically connected, and the second movable block and the second rack portion are magnetically connected.

[0014] In some embodiments, magnetic elements are embedded in both the first movable block and the first rack portion, and magnetic elements are also embedded in both the second movable block and the second rack portion.

[0015] The tooling for testing an upper limb tremor stimulator provided in this application has at least one of the following beneficial effects:

[0016] 1. This application provides a fixture for testing an upper limb tremor stimulator. By setting a first gripper and a first probe, the pressing end of the first gripper can quickly switch between lifting and pressing actions by moving the gripper handle. When the watch strap is placed in the watch strap clamping position, operating the gripper handle causes the pressing end of the first gripper to press down, clamping the stimulator's watch strap between the first probe and the pressing end of the first gripper. The first probe contacts the electrode on the inner side of the watch strap, achieving a conductive connection between the first probe and the electrode. By setting a second gripper and a second probe, the pressing end of the second gripper can quickly switch between lifting and pressing actions by moving the gripper handle. When the dial is placed in the dial clamping position, operating the gripper handle causes the pressing end of the second gripper to press down, clamping the stimulator's dial between the second probe and the pressing end of the second gripper. The second probe contacts the electrode on the inner side of the dial, achieving a conductive connection between the second probe and the electrode. This application utilizes a first gripper and a second gripper to achieve rapid clamping or release of the stimulator, facilitating operation and significantly reducing testing time, making the testing process more convenient and efficient. Furthermore, this application has a high degree of integration, while ensuring good contact between the probes (first probe and second probe) and the electrodes, resulting in more accurate testing results.

[0017] 2. The tooling for testing an upper limb tremor stimulator provided in this application, through the movable setting of the first probe and the second probe, enables the same set of dial clamping positions and strap clamping positions to adapt to stimulators of different specifications (mainly different strap lengths), thereby improving the versatility of the same set of dial clamping positions and strap clamping positions, and eliminating the need to configure a separate set of dial clamping positions and strap clamping positions for stimulators of different specifications.

[0018] 3. The fixture for testing an upper limb tremor stimulator provided in this application, by setting a first strip-shaped hole / second strip-shaped hole, can make way for the first probe / second probe after connecting the wire, so that the first probe / second probe will not interfere with the first mounting plate / second mounting plate when it moves in position with the first moving block / second moving block. By engaging the first engaging part / second engaging part with different positions of the first rack part / second rack part, the position of the first probe / second probe can be adjusted, thereby making the same set of dial clamping positions and strap clamping positions adaptable to stimulators of different specifications (mainly different strap lengths). Furthermore, the first rack / second rack portion is connected to the first engaging portion / second engaging portion by a snap-fit ​​mechanism. This facilitates quick disconnection of the first moving block / second moving block from the first rack / second rack portion, allowing for rapid adjustment of the position of the first moving block / second moving block. On the other hand, after the first gripper / second gripper presses down on the stimulator, the connection between the first rack / second rack portion and the first moving block / second moving block remains stable, preventing the first moving block / second moving block from accidentally moving (deviating) along the length of the stimulator.

[0019] 4. The tooling for testing an upper limb tremor stimulator provided in this application can restrict the first moving block / second moving block between the two first abutting surfaces / two second abutting surfaces by setting a first abutting surface / second abutting surface, thereby preventing the first moving block / second moving block from moving in a direction perpendicular to the first strip hole / second strip hole, and ensuring good contact between the first probe / second probe of the first moving block / second moving block and the electrode.

[0020] 5. The tooling for testing an upper limb tremor stimulator provided in this application can prevent the stimulator from falling off by fixing one end of the stimulator strap with screws, and the tester does not need to hold the stimulator, making the test convenient and efficient.

[0021] 6. The tooling for testing an upper limb tremor stimulator provided in this application, by setting a third mounting plate and a handle on the third mounting plate, facilitates the lifting, raising or raising of the tooling to achieve the purpose of moving or transporting the tooling. On the other hand, since the handle is not set on the first mounting plate and the second mounting plate, it will not affect the placement or installation of instruments and equipment on the first mounting plate and the second mounting plate.

[0022] 7. The tooling for testing an upper limb tremor stimulator provided in this application, by setting a pad that can cover the electrodes on the strap, allows the strap to be evenly stressed when pressed by the first clamping hand, ensuring that the first probe and the electrodes on the stimulator strap can be tightly abutted and maintain good conductive connection.

[0023] 8. The fixture for testing an upper limb tremor stimulator provided in this application, through the magnetic connection between the first moving block / second moving block and the first rack / second rack, can improve the positional stability of the first moving block / second moving block and reduce the risk of the first moving block / second moving block accidentally falling off the first mounting plate / second mounting plate. At the same time, the magnetic connection does not affect the rapid adjustment of the position of the first moving block / second moving block. Attached Figure Description

Detailed Implementation

[0036] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0037] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0038] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0039] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] refer to Figures 1-9This application provides a tooling for testing an upper limb tremor stimulator, including a first mounting plate 1 and a second mounting plate 2, which are arranged adjacent to each other. The first mounting plate 1 has a strap clamping station, and the second mounting plate 2 has a dial clamping station. A strap clamping assembly is provided at the strap clamping station, including a first gripper 3 and a first probe 5. Both the first probe 5 and the first gripper 3 are mounted on the first mounting plate 1, with the first gripper 3 located on one side of the first probe 5. The first gripper 3 can clamp the stimulator... The strap 13-1 of 13 is pressed down so that the first probe 5 abuts against the electrode 13-3 on the strap 13-1 of the stimulator 13; a dial clamping assembly is provided at the dial clamping station, which includes a second clamp 4 and a second probe 6. The second probe 6 and the second clamp 4 are both mounted on the second mounting plate 2. The second clamp 4 is located on one side of the second probe 6. The second clamp 4 can press down the dial 13-2 of the stimulator 13 so that the second probe 6 abuts against the electrode 13-3 on the dial 13-2 of the stimulator 13.

[0042] Specifically, the first probe 5 and the second probe 6 can be one, two, or other quantities. The number of the first probe 5 and the second probe 6 corresponds to the number of electrodes 13-3 on the strap 13-1 and the number of electrodes 13-3 on the dial 13-2, respectively. The first probe 5 and the second probe 6 are connected to the instrument (not shown in the figure) of the stimulator 13 via wires to detect the electrical signal output by the upper limb tremor stimulator 13 and analyze whether its voltage, current, and other parameters meet the standards. The first mounting plate 1 and the second mounting plate 2 can be set at a preset angle, such as 45°, 60°, 90°, 135°, etc., or they can be set on the same plane. The first gripper and the second gripper are both quick clamps (or quick clamps), specifically horizontal quick clamps or vertical quick clamps.

[0043] Understandably, by setting the first gripper 3 and the first probe 5, the pressing end of the first gripper 3 can quickly switch between lifting and pressing actions by moving the handle of the first gripper 3. When the watch strap 13-1 is placed in the watch strap clamping position, operating the handle of the first gripper 3 can cause the pressing end of the first gripper 3 to complete the pressing action, clamping the watch strap 13-1 of the stimulator 13 between the first probe 5 and the pressing end of the first gripper 3. The first probe 5 contacts the electrode 13-3 on the inner side of the watch strap 13-1, realizing the conductive connection between the first probe 5 and the electrode 13-3. By setting the second gripper 4 and the second probe 6, the pressing end of the second gripper 4 can quickly switch between lifting and pressing actions by moving the handle of the second gripper 4. When the dial 13-2 is placed in the dial clamping position, operating the handle of the second clamp 4 allows the pressing end of the second clamp 4 to press down, clamping the dial 13-2 of the stimulator 13 between the second probe 6 and the pressing end of the second clamp 4. The second probe 6 contacts the electrode 13-3 on the inner side of the dial 13-2, achieving a conductive connection between the second probe 6 and the electrode 13-3. This application utilizes the first clamp 3 and the second clamp 4 to achieve rapid clamping or release of the stimulator 13, facilitating operation, greatly saving detection time, and making the detection process more convenient and efficient. In addition, this application has a high degree of integration and can ensure good contact between the probes (first probe 5 and second probe 6) and the electrode 13-3, making the detection results more accurate.

[0044] refer to Figures 1-7 In one embodiment, the first probe 5 is movable on the first mounting plate 1, and the second probe 6 is movable on the second mounting plate 2.

[0045] It is easy to understand that by making the first probe 5 and the second probe 6 movable, the same set of dial clamping stations and strap clamping stations can be adapted to stimulators 13 of different specifications (mainly different strap lengths 13-1), which improves the versatility of the same set of dial clamping stations and strap clamping stations, and eliminates the need to configure a separate set of dial clamping stations and strap clamping stations for stimulators 13 of different specifications.

[0046] refer to Figures 3-7In one embodiment, the first mounting plate 1 has a first strip-shaped hole 1-1, and a first rack portion 1-2 is provided on both sides of the first strip-shaped hole 1-1. The first probe 5 is mounted on the first moving block 7. The bottom of the first moving block 7 is provided with a first engaging portion 7-1 that is adapted to the first rack portion 1-2. The first rack portion 1-2 is engaged with the first engaging portion 7-1. The first strip-shaped hole 1-1 is used to make way for the movement of the first probe 5. The second mounting plate 2 has a second strip-shaped hole 2-1, and a second rack portion 2-2 is provided on both sides of the second strip-shaped hole 2-1. The second probe 6 is mounted on the second moving block 8. The bottom of the second moving block 8 is provided with a second engaging portion 8-1 that is adapted to the second rack portion 2-2. The second rack portion 2-2 is engaged with the second engaging portion 8-1. The second strip-shaped hole 2-1 is used to make way for the movement of the second probe 6.

[0047] It should be noted that by setting the first strip-shaped hole 1-1 / second strip-shaped hole 2-1, space can be provided for the first probe 5 / second probe 6 after connecting the wire. This ensures that the first probe 5 / second probe 6 will not interfere with the first mounting plate 1 / second mounting plate 2 when its position changes with the first moving block 7 / second moving block 8. By engaging the first engaging part 7-1 / second engaging part 8-1 at different positions with the first rack part 1-2 / second rack part 2-2, the position of the first probe 5 / second probe 6 can be adjusted, thereby allowing the same set of dial clamping positions and strap clamping positions to accommodate stimulators 13 of different specifications (mainly different strap lengths 13-1). Furthermore, the first rack portion 1-2 / second rack portion 2-2 is connected to the first engaging portion 7-1 / second engaging portion 8-1 by a snap-fit ​​mechanism. This facilitates quick disconnection of the first moving block 7 / second moving block 8 from the first rack portion 1-2 / second rack portion 2-2, allowing for rapid adjustment of the position of the first moving block 7 / second moving block 8. On the other hand, after the first clamp 3 / second clamp 4 presses down on the stimulator 13, the connection between the first rack portion 1-2 / second rack portion 2-2 and the first moving block 7 / second moving block 8 becomes stable, preventing accidental movement (accidental deviation) of the first moving block 7 / second moving block 8 along the length of the stimulator 13.

[0048] refer to Figures 4-6 In one embodiment, the first rack portion 1-2 has a first abutting surface 1-3 on the side away from the first strip-shaped hole 1-1, and the two ends of the first moving block 7 abut against the corresponding first abutting surface 1-3 respectively; the second rack portion 2-2 has a second abutting surface 2-3 on the side away from the second strip-shaped hole 2-1, and the two ends of the second moving block 8 abut against the corresponding second abutting surface 2-3 respectively.

[0049] It is understandable that by setting the first contact surface 1-3 and the second contact surface 2-3, the first moving block 7 and the second moving block 8 can be restricted between the two first contact surfaces 1-3 and the two second contact surfaces 2-3, which can prevent the first moving block 7 and the second moving block 8 from moving in a direction perpendicular to the first strip hole 1-1 and the second strip hole 2-1, and ensure that the first probe 5 and the second probe 6 of the first moving block 7 and the second moving block 8 are in good contact with the electrode 13-3.

[0050] refer to Figure 1 , Figure 2 In one embodiment, the tooling further includes a rectangular box, the top surface of which is a first mounting plate 1, and the side surface of which is a second mounting plate 2. In other embodiments, the overall shape of the tooling can be other shapes, such as a triangular prism, a pentagonal prism, a hexagonal prism, or a biomimetic shape that mimics the shape of a wrist.

[0051] refer to Figures 1-6 In one embodiment, the first mounting plate 1 is provided with a first screw hole, and a screw 9 is screwed into the first screw hole. The screw 9 is used to fix one end of the stimulator 13 strap 13-1. By fixing one end of the stimulator 13 strap 13-1 with the screw 9, the stimulator 13 can be prevented from falling off, and the testing personnel do not need to hold the stimulator 13, making the testing convenient and efficient.

[0052] refer to Figure 1 , Figure 2 In one embodiment, the housing includes two opposing third mounting plates 10, which are perpendicular to the first mounting plate 1 and the second mounting plate 2, respectively. Each third mounting plate 10 has a handle 11. By providing the third mounting plates 10 and the handles 11 on them, it is convenient to lift, raise, or haul the tooling using the handles 11, thus facilitating the movement or transport of the tooling. Furthermore, since the handles 11 are not located on the first mounting plates 1 and 2, they do not interfere with the placement or installation of instruments and equipment on the first and second mounting plates 1 and 2.

[0053] refer to Figures 1-3 In one embodiment, the pressing end of the first gripper 3 is equipped with a pad 12, which can cover the electrode 13-3 on the strap 13-1 of the stimulator 13 so that the first probe 5 is in close contact with the electrode 13-3 on the strap 13-1 of the stimulator 13.

[0054] It is understandable that by setting the pad 12 and the pad 12 being able to cover the electrode 13-3 on the strap 13-1, the strap 13-1 can be evenly stressed when it is pressed down by the first clamp 3, ensuring that the first probe 5 and the electrode 13-3 on the strap 13-1 of the stimulator 13 can be tightly abutted and maintain a good conductive connection.

[0055] In one embodiment, the first movable block 7 and the first rack portion 1-2 are magnetically connected, and the second movable block 8 and the second rack portion 2-2 are magnetically connected. The magnetic connection between the first movable block 7 / second movable block 8 and the first rack portion 1-2 / second rack portion 2-2 improves the positional stability of the first movable block 7 / second movable block 8 and reduces the risk of accidental detachment from the first mounting plate 1 / second mounting plate 2. Simultaneously, the magnetic connection does not affect the rapid adjustment of the position of the first movable block 7 / second movable block 8.

[0056] In one specific embodiment, the first moving block 7, the second moving block 8, the first rack portion 1-2, and the second rack portion 2-2 are all made of plastic. Magnetic elements are embedded in both the first moving block 7 and the first rack portion 1-2, as well as in the second moving block 8 and the second rack portion 2-2. In another specific embodiment, the first moving block 7 and the second moving block 8 are both made of a magnetic material, while the first rack portion 1-2 and the second rack portion 2-2 are both made of plastic. Magnetic elements are embedded in both the first rack portion 1-2 and the second rack portion 2-2. Both methods can reduce the manufacturing cost of the tooling.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
