Description

Technical Field

[0001] The present invention relates to the field of equipment assisting gastroscopy, and in particular to equipment assisting medical examination and a working method thereof. Background Art

[0002] It is well known that Helicobacter pylori is a Gram-negative Helicobacter pylori that exists in the human stomach and mouth. Infection with this bacterium is related to a variety of gastrointestinal diseases such as gastritis, gastric ulcer, and gastric cancer. Therefore, detection of Helicobacter pylori is also one of the focuses of gastroscopy in medical treatment.

[0003] There are various inspection methods at present, but without exception, they all require mixing the test sample obtained from the body of the person to be inspected and the indicator. For example, the method and kit for rapid detection of Helicobacter pylori in saliva disclosed in application No. 201410531679.7 require that the saliva (i.e., the test sample) and the test solution (i.e., the configured indicator) be fully mixed and reacted, and then the reaction solution is tested with pH test paper.

[0004] In the prior art, the mixing method generally involves pouring the test sample and the indicator into the same test tube and having the medical staff shake the test tube to mix the test sample and the indicator. When there are many people who need to undergo gastroscopy, it is troublesome to mix each test sample and the indicator manually one by one, and there is a risk of the test tube falling out of the hands and breaking, so it is relatively dangerous. Summary of the invention

[0005] In view of the deficiencies raised by the above-mentioned background technology, the present invention provides a device for assisting medical examination and a working method thereof.

[0006] The present invention adopts the following technical solution: In a first aspect, the present invention discloses a device for assisting medical examination, the device comprising: A workbench, wherein the workbench has a through hole, and a shaft sleeve is fixed on the bottom surface of the workbench at a position corresponding to the through hole; A placement assembly, the placement assembly comprising a moving rod and a clamping member, the clamping seat is fixed on both sides of the upper end of the moving rod, and the clamping seat is used to place the test tube; A transmission mechanism, the transmission mechanism comprising an outer sleeve, an inner sleeve and a lifting member, the outer sleeve and the inner sleeve are radially fixed to each other, the outer sleeve is sleeved outside the shaft sleeve and is axially fixed and rotated relative to the shaft sleeve, the inner sleeve is embedded in the shaft sleeve, the moving rod passes through the inner sleeve and is connected to the lifting member and is rotatable relative to the lifting member, and the moving rod is radially fixed and can be lifted and lowered relative to the inner sleeve; A driving mechanism, the driving mechanism comprising a driving member and a crank, the driving member having a first rotating shaft and a driving rod, the middle of the driving rod being fixed to one end of the first rotating shaft, the two ends of the crank being fixed to a second rotating shaft and a guide shaft on opposite sides, the first rotating shaft and the second rotating shaft being restricted from rotating under the workbench, and the first rotating shaft and the second rotating shaft being in transmission connection; One side of the outer ring surface of the outer sleeve is inwardly recessed to form two spiral grooves, and the two spiral grooves are arranged in a mirror-image manner. The first rotating shaft rotates to the two ends of the driving rod and respectively embeds into the two spiral grooves to drive the outer sleeve to rotate 180° forward and 180° reversely. The lifting member has an arc groove, and the guide shaft is embedded in the arc groove, so that when the second rotating shaft rotates to drive the crank to rotate, the guide shaft pushes the arc groove to drive the lifting member to rise and fall.

[0007] In a possible implementation of the first aspect, a receiving groove is provided at the bottom of the clamping seat, the receiving groove is used to embed the bottom of the test tube, and a clip is provided on the side of the clamping seat facing the receiving groove, the cross-section of the clip is C-shaped, and the clip corresponds to the top of the receiving groove, the clip has expansion elasticity, and the clip is used to clamp the test tube.

[0008] In a possible implementation of the first aspect, a side of the sleeve facing away from the driving member is provided with a accommodating groove extending through the inside and outside, and a positioning bolt is spirally connected to one side outside the inner sleeve. After the positioning bolt is inserted into the outer sleeve, it is inserted into the accommodating groove and then spirally connected to the inner sleeve for tightening, so that the outer sleeve and the inner sleeve are radially fixed to each other, and when the inner sleeve rotates relative to the sleeve, the positioning bolt moves relative to the accommodating groove.

[0009] In a possible implementation of the first aspect, the upper end of the lifting member is embedded and fixed in the second bearing, the lower end of the moving rod is inserted into the inner ring of the second bearing with an interference fit, and the moving rod is fixed relative to the inner ring of the second bearing.

[0010] In a possible implementation of the first aspect, a raised limiting rib is provided on one side outside the moving rod, and a recessed limiting groove is provided on one side inside the inner sleeve. The limiting rib is loosely fitted in the limiting groove to radially fix the moving rod relative to the inner sleeve.

[0011] In a possible implementation of the first aspect, the driving member also includes a connecting rod and an arc plate, the connecting rod and the driving rod are fixed perpendicularly to each other at one end of the first rotating shaft, and the first rotating shaft is located at the intersection of the connecting rod and the driving rod; the arc plate is fixed at both ends of the connecting rod, and both ends of the outer sleeve extend outward to form a positioning portion, and positioning grooves are provided on both sides corresponding to the positioning portion, and the positioning grooves on both sides of the same positioning portion are respectively connected to the same end of the two spiral grooves; when the driving rod rotates to leave the spiral groove, the arc plate rotates accordingly to pass through the positioning groove.

[0012] In a possible implementation manner of the first aspect, the driving mechanism further includes a driving motor, and the driving motor drives the first rotating shaft or the second rotating shaft to rotate.

[0013] In a possible implementation of the first aspect, the first rotating shaft fixes a first synchronous wheel, the second rotating shaft fixes a second synchronous wheel, and both the first synchronous wheel and the second synchronous wheel are meshed and connected with a synchronous belt.

[0014] In a second aspect, the present invention also discloses a working method of the above device, which is as follows: The driving member rotates to rotate the driving rod until the end thereof penetrates into the positive spiral groove, thereby driving the outer sleeve and the moving rod to rotate positively, thereby driving the clamping seat on which the test tube is placed to rotate 180° to the other side of the workbench. At the same time, the crank rotates to rotate one end of the guide shaft in the arc groove toward the other end. Therefore, the lifting member does not rotate at this time, and the moving rod and the clamping seat do not rise or fall relative to the workbench. After the driving member rotates until the end of one end of the driving rod leaves the positive spiral groove, the outer sleeve loses the drive and stops rotating, so that the moving member and the clamping seat also stop rotating. At the same time, the crank rotates downward to make the guide shaft continue to rotate downward from the end of the arc groove 332 to press the lifting member downward, so that the moving rod descends and drives the clamping seat to descend. Then, the crank rotates upward to make the guide shaft move from one end of the arc groove to the other end to lift the lifting member, so that the moving rod rises and drives the clamping seat to rise. The driving member rotates until the end portion of the other end of the driving rod penetrates into the reverse spiral groove, thereby driving the outer sleeve to rotate in the reverse direction. The rotation of the outer sleeve drives the inner sleeve to rotate while driving the moving rod to rotate accordingly, thereby driving the clamping seat without a test tube to rotate 180° to one side of the workbench. At the same time, the crank rotates to rotate the guide shaft from one end in the arc groove to the other end. Therefore, the lifting member will not rotate at this time, and the moving rod and the clamping seat will not rise or fall relative to the workbench. At this time, the test tube filled with the test sample and indicator can be placed in the clamping seat.

[0015] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the present invention can drive the outer sleeve to rotate relative to the workbench and drive the lifting member to lift relative to the workbench through the synchronous operation of the driving member and the crank, so as to realize driving the moving rod to rotate 180°, lift it once, and then rotate it 180° in the opposite direction, so that medical personnel can first place the test tube to be identified on the clamping seat 22 on one side of the moving member during identification, and rotate the test tube 180° from one side of the workbench to the other side, and then the test tube undergoes another lifting and lowering, so that the test sample and indicator in the test tube can form a mixed action of rotational shaking and up and down shaking, and move to the other side of the workbench after mixing, so that medical personnel can remove the test tube after the test sample and indicator are mixed, and at the same time, the test tube containing the sample to be detected and the indicator can be placed on the other side of the workbench again. It can be seen that the present invention can place test tubes containing samples to be tested and indicators on one side of the workbench while taking down test tubes in which the test samples and indicators are mixed on the other side of the workbench, so that medical personnel can continuously complete the mixing of the test samples and indicators in each test tube only by continuously taking and placing the test tubes on both sides of the workbench. In this process, there is no need to manually shake each test tube containing the test sample and indicator one by one, which is more labor-saving and is beneficial to improving the efficiency of gastroscopy. At the same time, it can also avoid the test tubes from falling out of the hands and causing them to break during the shaking process, so it is also safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0032] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0033] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0034] The present invention provides a device for assisting medical examination and a working method thereof, as shown in the attached Figures 1 to 3 As shown, the device includes a workbench 1, a placement component, a transmission mechanism and a driving mechanism. Among them, the placement component includes a moving rod 21 and a clamping seat 22. The clamping seats 22 are fixed on both sides of the upper end of the moving rod 21. The two clamping seats 22 are used to place test tubes 5, which are containers for mixing samples to be tested and indicators. The transmission mechanism and the transmission mechanism are both arranged under the workbench 1, and are used to drive the moving rod 21 to rotate and lift relative to the workbench 1, so that the test tubes 5 of the two clamping seats 22 rotate and lift relative to the workbench 1. The test samples and indicators in the test tubes 5 are fully mixed by utilizing this lifting and rotating process. At the same time, when one clamping seat 22 drives the test tube 5 to rotate and lift for mixing, the other clamping seat 22 moves to the initial position accordingly to facilitate medical personnel to place the test tube 5 containing the sample to be tested and the indicator again.

[0035] Preferably, a protective cover 12 is fixed under the workbench 1, and the protective cover 12 is used to cover the placement components, transmission mechanism and drive mechanism to form a protective effect and support the entire device.

[0036] As attached Figure 3 and 4 As shown, the workbench 1 has a through hole, and a sleeve 11 is fixed on the bottom surface of the workbench 1 at a position corresponding to the through hole. The sleeve 11 is a tubular structure that passes through from top to bottom, and a flange is provided at one end of the sleeve 11. The flange is connected to the bottom surface of the workbench 1, so that the sleeve 11 can be fixed to the bottom of the workbench 1.

[0037] Please refer to the attached Figure 3 , both sides of the upper end of the moving rod 21 are fixed with a clamping seat 22, and the clamping seat 22 is used to place the test tube 5. Figure 2 The structure of the clamping seat 22 can be L-shaped, a receiving groove 221 is provided at the bottom of the clamping seat 22, a clip 222 is provided on one side of the clamping seat 22 facing the receiving groove 221, the clip 222 corresponds to the upper part of the receiving groove 221, and the cross section of the clip 222 is C-shaped, and the clip 222 can be a metal part bent by sheet metal or a plastic part molded by injection molding, so that the clip 222 has elasticity after expansion and contraction, so that the clip 222 can be used to clamp the test tube 5. When placing the test tube 5, the test tube 5 can be inserted into the clamping seat 22 from top to bottom until the bottom of the test tube is embedded in the receiving groove 221, and the clip 222 clamps the tube wall of the test tube 5. In addition, the clamping seat 22 and the cross bar 23 can be fixed by wearing connecting bolts to facilitate the replacement of clips 222 of different sizes, so that the placement assembly can be suitable for placing test tubes 5 of different sizes.

[0038] Please refer to the attached Figure 1 , 2As shown in 8, the upper end of the movable rod 21 is fixed with the cross bar 23, and the two clamping seats 22 are respectively fixed to the two cross bars 23. The placement assembly may also include a covering plate 24, and guide rods 241 are fixed on both sides under the covering plate 24. The lower ends of the two guide rods 241 pass through the guide holes set on both sides of the cross bar 23 and are screwed to the fixed limiting parts 242, and the two guide rods 241 are respectively covered with springs 243. The upper ends of the springs 243 are respectively against the bottom of the cross bar 23 and the limiting parts 242. The elastic force of the springs 243 is used to push the limiting parts 242 downward, so that the covering plate 24 moves toward the direction of the cross bar 23, so that the covering plate 24 can seal the tube mouth of the test tube 5 to prevent the detection sample and indicator from being thrown out of the tube mouth of the test tube 5 during the mixing process in the test tube 5. Specifically, when placing the test tube 5, the cover plate 24 can be pulled up, and then the test tube 5 can be tilted so that the bottom of the test tube 5 is embedded in the receiving groove 221, and then the test tube 5 is straightened and vertically clamped in the clamp 222, and finally the cover plate 24 is released, so that the cover plate 24 can seal the mouth of the test tube 5. In addition, a guide slope can be provided on the lower edge of the cover plate 24, so that the test tube 5 can be clamped into the clamp seat 22 along the guide slope, which is more convenient. Preferably, a layer of rubber pad (not marked in the figure) can be pasted and provided at the position of the cover plate 24 corresponding to the clamp seat 22, and the rubber pad is pressed against the mouth of the test tube 5 to achieve sealing of the mouth of the test tube 5, and at the same time, the buffer formed by the softness of the rubber pad is used to prevent the cover plate 24 from crushing the test tube 5.

[0039] As attached Figure 4 and 5 As shown, the transmission mechanism includes an outer sleeve 31, an inner sleeve 32 and a lifting member 33. The outer sleeve 31 is sleeved outside the sleeve 11 and rotates fixedly relative to the axial direction of the sleeve 11. Preferably, first bearings 311 are embedded in the upper and lower ends of the outer sleeve 31, and a shoulder 111 is provided at the upper end of the sleeve 11. The sleeve 11 is adapted to pass through the inner rings of the two first bearings 311, so that the upper first bearing 311 is against the shoulder 111, and the sleeve 11 is equipped with a retaining spring on the lower surface of the lower first bearing 311 to limit the outer sleeve 31 between the shoulder 111 and the retaining spring, so that the outer sleeve 31 is fixed axially relative to the sleeve 11 and cannot slide vertically, and the friction of the outer sleeve 31 rotating relative to the sleeve 11 can be reduced through the connection of the first bearing 311, so that the equipment can run more smoothly. The inner sleeve 32 is embedded in the sleeve 11, and the inner sleeve 32 and the outer sleeve 31 are radially fixed to each other. The fixing method can be as shown in the attached Figure 4 , 9As shown in FIG. 11 , a side of the sleeve 11 facing away from the drive member 41 is provided with a clearance groove 112 that penetrates inside and outside, and a positioning bolt 321 is screwed on one side outside the inner sleeve 32. After the positioning bolt 321 is inserted into the outer sleeve 31, it passes through the clearance groove 112 and is screwed and fastened to the inner sleeve 32. The outer sleeve 31 and the inner sleeve 32 are radially fixed to each other through the connection of the positioning bolt 321, that is, the inner sleeve 32 rotates with the rotation of the outer sleeve 31. When the outer sleeve 31 drives the inner sleeve 32 to rotate relative to the sleeve 11, the positioning bolt 321 moves relative to the receiving groove 221.

[0040] As attached Figure 8 and 9 As shown, a raised limiting rib 211 is provided on one side outside the moving rod 21, and a recessed limiting groove 322 is provided on one side inside the inner sleeve 32. When the moving rod 21 passes through the inner sleeve 32, the limiting rib 211 is loosely fitted in the limiting groove 322, so that the moving rod 21 is radially fixed relative to the inner sleeve 32, that is, when the inner sleeve 32 rotates, the moving rod 21 is driven to rotate, thereby causing the clamping seats 22 connected on both sides of the upper end of the moving rod 21 to rotate accordingly.

[0041] Please refer to the attached Figure 4 The lower end of the moving rod 21 after passing through the inner sleeve 32 is connected to the lifting member 33, and the moving rod 21 is rotatable relative to the lifting member 33. The connection method can be that the upper end of the lifting member 33 is embedded with a fixed second bearing 331, and the lower end of the moving rod 21 is inserted into the inner ring of the second bearing 331 with an interference fit, and the moving rod 21 can be equipped with retaining springs on both sides of the inner ring of the second bearing 331, so that the moving rod 21 is fixed relative to the inner ring of the second bearing 331, so that the lifting member 33 will not affect the rotation of the moving rod 21. At the same time, the lifting member 33 can also drive the moving rod 21 and the clamping seat 22 connected on both sides of the upper end of the moving rod 21 to rise and fall while the workbench 1 is raised and lowered.

[0042] Preferably, the limiting rib 211 can be a slide rail fixed outside the moving rod 21, which is adapted to be a sliding connection slider, and the slider is embedded in and fixed in the limiting groove 322, so as to reduce the friction force of the axial sliding of the moving rod 21 relative to the inner sleeve 32, which is also beneficial to improving the smoothness of the operation of the equipment.

[0043] As attached Figure 5 and 6 As shown in FIG. 4 , the transmission mechanism includes a driving member 41, a crank 42 and a driving motor 43. Figure 7The driving member 41 has a first rotating shaft 411 and a driving rod 412, the center of the driving rod 412 is fixed at one end of the first rotating shaft 411, and the two ends of the crank 42 are fixed on opposite sides of the second rotating shaft 421 and the guide shaft 422. Two bearing seats are fixed under the workbench 1 through a bracket, and the first rotating shaft 411 and the second rotating shaft 421 are respectively connected to the two bearing seats, so that the first rotating shaft 411 and the second rotating shaft 421 are both restricted to rotate under the workbench 1. And the first rotating shaft 411 and the second rotating shaft 421 can also be connected by transmission, and the transmission connection mode can be that the first rotating shaft 411 fixes the first synchronous wheel 431, and the second rotating shaft 421 fixes the second synchronous wheel 431, and the first synchronous wheel 431 and the second synchronous wheel 431 are both meshed and connected with a synchronous belt 432. Further, the driving motor 43 is fixed under the workbench 1, and the driving motor 43 drives the first rotating shaft 411 or the second rotating shaft 421 to rotate, so as to realize the synchronous rotation of the driving member 41 and the crank 42.

[0044] As attached Fig.10 As shown, one side of the outer ring surface of the outer sleeve 31 is inwardly recessed to form two spiral grooves 312, and the two spiral grooves 312 are arranged in a mirror-image manner, that is, one of the two spiral grooves 312 is a forward spiral and the other is a reverse spiral, and the spiral groove 312 in this embodiment only intercepts half of the spiral line. Fig.12 and 13 When the first rotating shaft 411 rotates until the two ends of the driving rod 412 are respectively embedded in the two spiral grooves 312, the outer sleeve 31 is driven to rotate 180° forward and 180° reversely. Specifically, when the end of the driving rod 412 on the left side swings upward to be embedded in the spiral groove 312 of the forward spiral, the driving rod 412 pushes the upper end of the spiral groove 312 to rotate the outer sleeve 31 forward 180°, and moves the port under the reverse spiral groove 312 to the side corresponding to the driving member 41; then, when the driving rod 412 on the right side swings upward to be embedded in the spiral groove 312 of the reverse spiral, the driving rod 412 pushes the upper end of the spiral groove 312 to reverse the outer sleeve 31 by 180°. Preferably, a roller 415 may be provided at the end of the driving rod 412, and the roller 415 may be a bearing. By inserting the roller 415 into the spiral groove 312, the friction between the roller 415 and the side wall of the spiral groove 312 may be reduced, which is conducive to making the device of the present invention run more smoothly.

[0045] Furthermore, the driving member 41 further includes a connecting rod 413 and an arc plate 414. The connecting rod 413 and the driving rod 412 are fixed perpendicularly to one end of the first rotating shaft 411, and the first rotating shaft 411 is located at the intersection of the connecting rod 413 and the driving rod 412. The arc plate 414 is fixed at both ends of the connecting rod 413, and both ends of the outer sleeve 31 extend outward to form a positioning portion 313. Both sides corresponding to the positioning portion 313 are provided with positioning grooves 314. The positioning grooves 314 on both sides of the same positioning portion 313 are connected and connected with the same end of the two spiral grooves 312 respectively.

[0046] As attached Fig.15 As shown, when the driving member 41 rotates to the end of the driving rod 412 and rotates to leave the spiral groove 312, the outer sleeve 31 is driven to rotate to the port under the other spiral groove 312 corresponding to the side of the driving member 41, so that the arc plate 414 rotates to pass through the positioning groove 314. After the arc plate 414 leaves the positioning groove 314, the other driving rod 412 rotates to penetrate into the spiral groove 312 from the lower end of the other spiral groove 312. During this process, the arc plate 414 can play a role in positioning the outer sleeve 31, so that the outer sleeve 31 maintains a stable state without rotation, thereby making the two clamping seats 22 on both sides of the moving rod 21 remain stationary and do not rotate. During this time, the test tube 5 can be removed from the clamping seat 22 and the test tube 5 can be placed in the clamping seat 22.

[0047] As attached Figure 6 and 14 As shown, the lifting member 33 has an arc groove 332, and the guide shaft 422 is embedded in the arc groove 332, so that when the second rotating shaft 421 rotates to drive the crank 42 to rotate, when the guide shaft 422 rotates from one end to the other end in the arc groove 332, since the guide shaft 422 and the arc groove 332 have the same trajectory, the guide shaft 422 is in an idling state at this time and will not drive the moving rod 21 to rise or fall. When the guide shaft 422 moves to the end of the arc groove 332, the crank 42 continues to rotate to drive the lifting member 33 to rise or fall. Specifically, during the process of the crank 42 rotating from top to bottom, the guide shaft 422 descends at the end of the arc groove 332 and drives the lifting member 33 to move downward, at which time the moving rod 21 can be pulled downward and the clamping seats 22 on both sides of the moving rod 21 can be driven downward; and during the process of the crank 42 rotating from bottom to top, the guide shaft 422 moves from the other end of the arc groove 332 to the previous end, and the lifting member 33 can be driven upward because the rotation trajectory of the guide shaft 422 is different from that of the arc groove 332, at which time the moving rod 21 can be pulled upward and the clamping seats 22 on both sides of the moving rod 21 can be driven upward. The lifting and lowering process of the clamping seat 22 can form a process of shaking the test sample and indicator in the test tube 5 up and down, so as to promote the uniform mixing of the test sample and indicator in the test tube 5.

[0048] In summary, the working method of the device of the present invention can be as follows: Pour the test sample and indicator into a test tube 5, and then place the test tube 5 on a clamping seat 22 at one side of the workbench 1; The driving member 41 rotates to rotate the driving rod 412 until the end thereof penetrates into the positive spiral groove 312, thereby driving the outer sleeve 31 to rotate in the positive direction. The outer sleeve 31 rotates while driving the inner sleeve 32 to rotate, and driving the moving rod 21 to rotate accordingly, thereby driving the clamping seat 22 on which the test tube 5 is placed to rotate 180° to the other side of the workbench 1. At the same time, the crank 42 rotates to rotate one end of the guide shaft 422 in the arc groove 332 toward the other end. Therefore, at this time, the lifting member 33 does not rotate, and the moving rod 21 and the clamping seat 22 do not rise or fall relative to the workbench 1. After the driving member 41 rotates until the end of one end of the driving rod 412 leaves the positive spiral groove 312, the outer sleeve 31 loses the drive and stops rotating, so that the moving rod 21 and the clamping seat 22 also stop rotating. At the same time, the crank 42 rotates downward to make the guide shaft 422 continue to rotate downward from the end of the arc groove 332 to press the lifting member 33 downward, so that the moving rod 21 is lowered and the clamping seat 22 is driven to lower. Then, the crank 42 rotates upward to make the guide shaft 422 move from one end of the arc groove 332 to the other end to lift the lifting member 33, so that the moving rod 21 is raised and the clamping seat 22 is raised. In this process, the clamping seat 22 experiences a process of falling and then rising, which can form a moving mode of shaking the test sample and indicator in the test tube 5 up and down, so that the test sample and indicator in the test tube 5 are evenly mixed, and then the test tube 5 can be removed; The driving member 41 rotates until the end of the other end of the driving rod 412 penetrates into the reverse spiral groove 312, thereby driving the outer sleeve 31 to rotate in the opposite direction. The outer sleeve 31 rotates while driving the inner sleeve 32 to rotate, and at the same time drives the moving rod 21 to rotate accordingly, thereby driving the clamping seat 22 without the test tube 5 placed thereon to rotate 180° to one side of the workbench 1. At the same time, the crank 42 rotates to rotate one end of the guide shaft 422 in the arc groove 332 toward the other end. Therefore, the lifting member 33 will not rotate at this time, and the moving rod 21 and the clamping seat 22 will not rise or fall relative to the workbench 1. At this time, the test tube 5 filled with the test sample and indicator can be placed in the clamping seat 22.

[0049] It can be known from the above working method that the present invention can drive the outer sleeve 31 to rotate relative to the workbench 1 and drive the lifting member 33 to lift and lower relative to the workbench 1 through the synchronous operation of the driving member 41 and the crank 42, thereby driving the moving rod 21 to rotate 180° and then lift and lower once, and then rotate 180° in the opposite direction, so that medical personnel can first place the test tube 5 to be identified on the clamping seat 22 on one side of the moving member during identification, and rotate the test tube 5 180° from one side of the workbench 1 to the other side, and then the test tube 5 undergoes another lifting and lowering, so that the test sample and indicator in the test tube 5 can form a mixed action of rotational shaking and up and down shaking, and after mixing, move to the other side of the workbench 1, so that the medical personnel can remove the test tube 5 after the test sample and indicator are mixed, and at the same time, the test tube 5 containing the sample to be detected and the indicator can be placed on the previous side of the workbench 1 again. It can be seen that the present invention can place a test tube 5 containing a sample to be tested and an indicator on one side of the workbench 1, and remove the test tube 5 in which the sample and the indicator are mixed on the other side of the workbench 1. There is no need to shake the test tube 5, which is more labor-saving and is beneficial to improving the efficiency of gastroscopy. It can also avoid the test tube 5 from falling out of the hand during the shaking process and causing it to break, so it is safer.

[0050] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.

A method for operating the device according to any one of claims 1 to 8, characterized in that: The working method is as follows: Pour the sample to be tested and the indicator into a test tube, and then place the test tube on one of the clamping seats on one side of the workbench; The driving member rotates to rotate the driving rod until the end thereof penetrates into the positive spiral groove, thereby driving the outer sleeve and the moving rod to rotate positively, thereby driving the clamping seat on which the test tube is placed to rotate 180° to the other side of the workbench. At the same time, the crank rotates to rotate one end of the guide shaft in the arc groove toward the other end. Therefore, the lifting member does not rotate at this time, and the moving rod and the clamping seat do not rise or fall relative to the workbench. After the driving member rotates until the end of one end of the driving rod leaves the positive spiral groove, the outer sleeve loses the drive and stops rotating, so that the moving member and the clamping seat also stop rotating. At the same time, the crank rotates downward to make the guide shaft continue to rotate downward from the end of the arc groove 332 to press the lifting member downward, so that the moving rod descends and drives the clamping seat to descend. Then, the crank rotates upward to make the guide shaft move from one end of the arc groove to the other end to lift the lifting member, so that the moving rod rises and drives the clamping seat to rise. The driving member rotates until the end portion of the other end of the driving rod penetrates into the reverse spiral groove, thereby driving the outer sleeve to rotate in the reverse direction. The rotation of the outer sleeve drives the inner sleeve to rotate while driving the moving rod to rotate accordingly, thereby driving the clamping seat without a test tube to rotate 180° to one side of the workbench. At the same time, the crank rotates to rotate the guide shaft from one end in the arc groove to the other end. Therefore, the lifting member will not rotate at this time, and the moving rod and the clamping seat will not rise or fall relative to the workbench. At this time, the test tube filled with the test sample and indicator can be placed in the clamping seat.
