Description

Technical Field

[0001] This application relates to the field of syringe booster device testing technology, and in particular to distance measuring and velocity testing fixtures. Background Technology

[0002] When injecting different medications into different locations on a patient's body using a syringe, the absorption rate of these medications varies at different locations. Therefore, it is necessary to control the injection speed to minimize discomfort and improve absorption. To achieve precise control of the injection speed, a syringe booster is used to propel the medication through the syringe at varying speeds.

[0003] In the field of medical aesthetics, syringe propulsion devices typically have different propulsion levels. When activated at a predetermined level for a preset time, the propulsion end of the device can move a predetermined distance in a predetermined direction within that time, thus pushing the syringe. Therefore, by switching between different levels of the syringe propulsion device, it is possible to achieve assisted injection of medication at different propulsion speeds.

[0004] To ensure that the boosting speed of the syringe booster at different speeds meets the requirements, the boosting speed of the syringe booster at different speeds needs to be tested after the syringe booster is manufactured and assembled.

[0005] In existing technologies, after the syringe propulsion device is manufactured and assembled, it needs to be started at different speeds for preset times. The movement distance of the propulsion end of the syringe propulsion device within these preset times at each speed is then manually measured to obtain the propulsion speed at each speed, thus determining whether the propulsion speed meets the expected range. However, because manual measurement of the propulsion end's movement distance is prone to error, the obtained propulsion speed test results at different speeds are easily deviated, making it impossible to accurately detect the movement speed of the propulsion end at different speeds.

[0024] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0025] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 5 A preferred embodiment of the distance measuring and speed testing fixture according to this application will be described in detail below, wherein the distance measuring and speed testing fixture includes a placement body 10, at least one fixing component 20 and a displacement detection component 30.

[0028] Specifically, the placement body 10 has a placement groove 101. A test subject 90 is placed in the placement groove 101. The moving direction of a pushing end 91 of the test subject 90 is parallel to the extending direction of the placement groove 101.

[0029] The fixing component 20 is disposed on the placement body 10 in such a way that it can fix the position of the subject 90 under test in the placement slot 101.

[0030] The displacement detection component 30 includes at least one mounting unit 31, one detection unit 32, and one display component 33. The detection unit 32 is mounted on the placement body 10 via the mounting unit 31. The detection unit 32 has a detection section 3221. The detection section 3221 is located on the movement path of the pushing end 91 of the subject under test 90, and is used to detect the movement distance of the pushing end 91. That is, when the subject under test 90 is activated for a preset time at different settings, and the pushing end 91 of the subject under test 90 moves along an extension direction parallel to the placement groove 101, the movement distance of the pushing end 91 of the subject under test 90 within the preset time of activation at different settings can be detected by the detection section 3221 of the detection unit 32. The display component 33 is mounted on the detection unit 32 and is electrically connected to the detection unit 32. The display component 33 is used to display the movement distance of the push end 91 detected by the detection unit 3221.

[0031] In one embodiment, the subject to be tested 90 is implemented as the injection handle of a hyaluronic acid injection device.

[0032] It should be noted that after the test subject 90 is started at a predetermined gear for a predetermined time, the pushing end 91 of the test subject 90 will move along the extension direction parallel to the placement groove 101 within the predetermined time at the corresponding predetermined gear. According to the speed calculation formula, since the predetermined time and predetermined gear at which the test subject 90 is started are predetermined, the speed at which the pushing end 91 moves at the predetermined gear is positively correlated with the distance the pushing end 91 moves.

[0033] In other words, after the test subject 90 is started for a preset time at a predetermined gear, by judging whether the moving distance of the push end 91 detected by the detection unit 3221 is within the expected range, it is possible to quickly determine whether the moving speed of the push end 91 of the test subject 90 at the corresponding predetermined gear meets the expectation. Compared with the method of manually measuring the moving distance of the push end 91, the distance measuring and speed testing fixture in this application can quickly and accurately obtain the moving distance of the push end 91, and thus quickly and accurately test the moving speed of the push end 91 of the test subject 90 at the corresponding predetermined gear, so as to quickly determine whether the moving speed of the push end 91 of the test subject 90 located in the placement slot 101 at the corresponding predetermined gear is qualified.

[0034] Preferably, the fixing component 20 has a pressing part 21. The pressing part 21 can approach and move away from the subject 90 to be tested in the placement groove 101, so that when the pressing part 21 approaches the subject 90 to be tested, the pressing part 21 of the fixing component 20 presses the subject 90 to be tested against the inner wall of the placement groove 101, thereby fixing the position of the subject 90 to be tested in the placement groove 101, preventing the subject 90 to be tested from shaking in the placement groove 101, and improving the stability of the subject 90 to be tested when placed in the placement groove 101.

[0035] It is understood that by pressing the subject 90 to be tested against the inner wall of the placement groove 101 by the pressing part 21 of the fixing component 20, the subject 90 to be tested can be started at a predetermined position for a predetermined time, and the pushing end 91 can be moved a distance parallel to the extension direction of the placement groove 101. This keeps the subject 90 to be tested stable relative to the placement body 10, preventing shaking, and ensuring the accuracy of the moving distance of the pushing end 91 detected by the detection unit 3221. This ensures accurate judgment of whether the moving speed of the pushing end 91 of the subject 90 to be tested is qualified at the corresponding predetermined position.

[0036] In this embodiment, the fixing component 20 is implemented to include a screw, the fixing component 20 passing through the inner wall of the placement groove 101 in a manner that maintains a threaded connection to the placement body 10, and the end of the fixing component 20 located in the placement groove 101 is defined as the top pressing part 21.

[0037] In other words, as the fixing component 20 rotates while maintaining its threaded connection to the placement body 10, and as the pressing portion 21 of the fixing component 20 continuously approaches the subject 90 to be tested, the pressing portion 21 of the fixing component 20 can press the subject 90 to be tested against the inner wall of the placement groove 101. Similarly, as the fixing component 20 rotates while maintaining its threaded connection to the placement body 10, and as the pressing portion 21 of the fixing component 20 continuously moves away from the subject 90 to be tested, the subject 90 to be tested can be easily removed from the placement groove 101.

[0038] As an example, the fixing component 20 is made of nylon. Compared to a fixing component 20 made of metal, the fixing component 20 made of nylon can reduce the scratches on the surface of the subject 90 when the pressing part 21 presses against the subject 90.

[0039] In another modified embodiment, the fixing component 20 is implemented as including a telescopic cylinder. The fixing component 20 is disposed on the placement body 10, and the telescopic end of the fixing component 20 is telescopically directed toward the test body 90 located in the placement groove 101, so that the telescopic end of the fixing component 20 is defined as the top pressure portion 21.

[0040] In other words, by extending and retracting the telescopic end of the fixing component 20, the pressing part 21 of the fixing component 20 can be brought close to and pressed against the subject 90 to be tested, and the pressing part 21 of the fixing component 20 can be moved away from the subject 90 to be tested.

[0041] The pressing part 21 of the fixing component 20 is covered with flexible materials including but not limited to rubber and silicone to prevent the pressing part 21 from scraping against the subject 90 under test.

[0042] Preferably, a pressure sensor is provided at the telescopic end of the fixing component 20. The pressure sensor is electrically connected to the fixing component 20 and is used to monitor the pressure of the pressing part 21 of the fixing component 20 pressing against the subject 90 under test, so as to control the movement of the pressing part 21 of the fixing component 20 in a timely manner and prevent the pressing part 21 from damaging the subject 90 under test.

[0043] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the fixing component 20 is implemented to include a screw, the fixing component 20 passing through the inner wall of the placement groove 101 in a manner that maintains a threaded connection to the placement body 10, and the end of the fixing component 20 located in the placement groove 101 is defined as the top pressure portion 21.

[0044] In this embodiment, the detection unit 32 includes a directional member 321 and a sliding member 322. The directional member 321 is implemented to include a fixed grid. The sliding member 322 is implemented to include a movable grid. The end of the directional member 321 is disposed on the placement body 10 via the mounting unit 31. The directional member 321 extends in an extension direction parallel to the placement groove 101. The sliding member 322 is held in contact with the directional member 321 in a manner that allows it to slide along the extension direction of the directional member 321. The portion of the sliding member 322 is located on the movement path of the pushing end 91 and is defined as the detection part 3221. The display member 33 is disposed on the sliding member 322 and is electrically connected to the sliding member 322.

[0045] It should be noted that the sliding member 322 has a reset button. After the subject 90 to be tested is placed in the placement groove 101, the sliding member 322 can be slid along the extension direction of the orientation member 321 in a way that keeps it locked to the orientation member 321, and the detection part 3221 of the sliding member 322 is kept in contact with the pushing end 91 of the subject 90 to be tested. Then, when the subject 90 to be tested is started at a predetermined position for a predetermined time, and the pushing end 91 moves along the extension direction parallel to the placement groove 101, the moving pushing end 91 pushes the detection part 3221, thereby pushing the sliding member 322 as a whole to move along the orientation member 321 in a way that keeps it locked to the orientation member 321.

[0046] Since the directional member 321 includes a fixed grid and the sliding member 322 includes a movable grid, when the reset button is pressed, the sliding member 322 moves along the directional member 321 while remaining engaged with it. The sliding member 322 can detect the distance it has moved along the extension direction of the directional member 321, thereby determining the moving distance of the pushing end 91. The moving distance of the pushing end 91 is then directly displayed by the display member 33 for easy judgment.

[0047] In another modified embodiment, the detection unit 32 is implemented to include a distance sensor, and the sensing end of the detection unit 32 is located on the movement path of the pushing end 91, which is defined as the detection unit 3221. Then, when the subject 90 is activated at a predetermined gear for a predetermined time and the pushing end 91 moves along the extension direction parallel to the placement groove 101, the movement distance of the pushing end 91 is detected by the detection unit 3221.

[0048] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the example is that the detection unit 32 includes the orientation member 321 and the sliding member 322, the orientation member 321 is implemented to include a fixed grid, and the sliding member 322 is implemented to include a moving grid.

[0049] Preferably, the placement body 10 has at least one pair of pick-and-place slots 102. The pair of pick-and-place slots 102 are kept in communication with the placement slot 101 in a relatively opposite manner. After a person reaches into the pair of pick-and-place slots 102, the subject 90 to be tested located in the placement slot 101 can be pinched and removed.

[0050] In this embodiment, the mounting unit 31 includes a mounting guide 311. The mounting guide 311 is mounted on the placement body 10. The mounting guide 311 extends in a direction offset from the moving path of the pushing end 91. The end of the directional member 321 is held in contact with the mounting guide 311 in a manner that allows it to slide along the extending direction of the mounting guide 311.

[0051] As an example, the end of the directional member 321 slides along the extension direction of the mounting guide 311 while being held in contact with the mounting guide 311. After the directional member 321 drives the detection part 3221 of the sliding member 322 away from the placement body 10, it is convenient to remove the subject 90 to be tested from the placement slot 101 and to place the subject 90 to be tested into the placement slot 101.

[0052] In another modified embodiment, the mounting unit 31 is implemented including a telescopic cylinder. The telescopic end of the mounting unit 31 extends and retracts in a direction deviating from the movement path of the pushing end 91. The end of the directional member 321 is disposed at the telescopic end of the mounting unit 31.

[0053] As an example, after the telescopic end of the mounting unit 31 extends out and the detection part 3221 of the sliding member 322 moves away from the placement body 10 through the directional member 321, it is convenient to remove the subject 90 to be tested from the placement slot 101 and to place the subject 90 to be tested into the placement slot 101.

[0054] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the example is simply that the mounting unit 31 includes the mounting guide 311, the mounting guide 311 is mounted on the placement body 10, the mounting guide 311 extends in a direction deviating from the moving path of the pushing end 91, and the end of the directional member 321 is held in contact with the mounting guide 311 in a manner that allows it to slide along the extending direction of the mounting guide 311.

[0055] In one embodiment, such as Figures 1 to 5 As shown, the mounting guide 311 extends in a horizontal direction perpendicular to the moving direction of the pushing end 91.

[0056] In another embodiment, the mounting guide 311 extends in a vertical direction perpendicular to the direction of movement of the push end 91 (not shown in the figure).

[0057] Preferably, the mounting unit 31 further includes at least one guide fastener 312. The guide fastener 312 is movably inserted through the guide member 321 in a manner that maintains a threaded connection to the guide member 321. The end of the guide fastener 312 can press against and away from the mounting guide member 311.

[0058] In other words, as the guide fixing member 312 is rotated in a manner that keeps it threadedly connected to the orienting member 321, the end of the guide fixing member 312 can be pressed against the mounting guide member 311 and away from the mounting guide member 311.

[0059] As an example, after the end of the directional member 321 slides along the extending direction of the mounting guide 311 while being held engaged with it, the position of the directional member 321 can be fixed by rotating the guide fixing member 312 and pressing its end against the mounting guide 311. Conversely, by rotating the guide fixing member 312 and moving its end away from the mounting guide 311, the end of the directional member 321 can be easily slid along the extending direction of the mounting guide 311 while being held engaged with it.

[0060] The guide fastener 312 is implemented by including screws.

[0061] Furthermore, the end of the guide fixing member 312 away from the mounting guide member 311 extends radially to form a turning portion 3121, so as to apply force through the turning portion 3121 to rotate the guide fixing member 312, thereby improving the ease of rotating the guide fixing member 312.

[0062] Preferably, the mounting guide 311 has a plurality of fixing holes 31101 along the extending direction, and the plurality of fixing holes 31101 correspond to and are adapted to the ends of the guide fixing member 312.

[0063] It is understood that the end of the directional member 321 slides along the extension direction of the mounting guide 311 in a manner that keeps it engaged with the mounting guide 311, and after the end of the guide fixing member 312 corresponds to one of the fixing holes 31101, by rotating the guide fixing member 312, the end of the guide fixing member 312 is inserted into the corresponding fixing hole 31101 and presses against the mounting guide 311, which can improve the stability of the guide fixing member 312, thereby improving the stability when fixing the position of the directional member 321.

[0064] Preferably, the ranging and speed measuring fixture further includes a control component (not shown in the figure). The control component is installed on the placement body 10 and electrically connected to the detection unit 32. The control component is used to convert the movement distance of the pushing end 91 detected by the sliding member 322 within a preset time at a predetermined gear into a movement speed at the predetermined gear and display it, so as to more intuitively determine whether the movement speed of the pushing end 91 at the predetermined gear meets expectations.

[0065] As an example, the display component 33 is implemented to include a display screen.

[0066] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
