Description

Technical Field

[0001] This invention relates to the field of blood testing equipment technology, and in particular to a cup-removing mechanism and a thromboelastography instrument. Background Technology

[0002] Thromboelastography (TEG) is an analyzer that monitors the entire dynamic process of coagulation, including platelet aggregation, coagulation, and fibrinolysis. A TEG mainly consists of a probe and a reaction cup. During operation, the probe is fixedly connected to the cup lid. After operation, the probe needs to be separated from the cup lid. Currently, separating the lid from the probe in existing TEG systems is generally done manually. However, manual operation is not only inefficient, but also carries the risk of operators accidentally touching blood samples contaminated on the lid, which can have health risks. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a cup cap removal mechanism and a thromboelastography instrument.

[0004] This invention provides the following technical solution:

[0005] A cup-cap ejection mechanism includes a toothed ring, a first ejection ring, a second ejection ring, and a bracket. The first ejection ring is disposed inside the toothed ring and slidably connected to it. The second ejection ring is located above the toothed ring and movably disposed on the first ejection ring. A probe passes through the first ejection ring, and a cup cap is disposed within the first ejection ring. The first ejection ring has a top tooth, the second ejection ring has a moving tooth, and the toothed ring has a first working groove corresponding to the moving tooth.

[0006] The bracket can drive the first cup-removing ring to move upward. When the top tooth moves upward, it can cooperate with the moving tooth, so that the moving tooth moves to the top of the first working groove. When the bracket moves downward, the moving tooth can move downward and insert into the first working groove, and drive the top tooth to move downward, so that the first cup-removing ring abuts against the cup cover and moves downward until the cup cover is separated from the probe.

[0007] In one possible implementation, the lower end of the moving tooth is provided with an inclined surface that engages with the top tooth, and the tooth ring is also provided with a second working groove corresponding to the inclined surface, the depth of the second working groove being less than the depth of the first working groove.

[0008] In one possible implementation, the first working groove and the second working groove are distributed sequentially at intervals on the gear ring, and an inclined portion that cooperates with the inclined surface is provided between the first working groove and the second working groove.

[0009] In one possible implementation, the cup-removing mechanism further includes a connecting post, which is disposed inside the first cup-removing ring, and the second cup-removing ring is sleeved on the connecting post. The moving tooth is capable of moving along the length direction of the connecting post and rotating along the circumferential direction of the connecting post, thereby moving above the first working groove.

[0010] In one possible implementation, the cup-removing mechanism further includes a retaining spring, and the connecting post is provided with a fixing groove, through which the retaining spring is fixed to the connecting post; the second cup-removing ring is located between the top tooth and the retaining spring.

[0011] In one possible implementation, the cup-removing mechanism further includes a support plate and a protective shell, the support plate and the protective shell being fixedly connected, the support plate and the protective shell having cavities inside, the toothed ring being fixed in the cavity, and the first cup-removing ring and the second cup-removing ring being movably disposed in the cavity.

[0012] In one possible implementation, the cup-removing mechanism further includes a spring disposed within the cavity, with one end of the spring abutting against the inner side of the support plate and the other end abutting against the upper end of the second cup-removing ring.

[0013] In one possible implementation, the cup-removing mechanism further includes a fixing member, a fixing block is provided on the outer side of the toothed ring, and a fixing hole is provided on the fixing block; a first sliding groove corresponding to the fixing block is provided on the inner side of the protective shell, and a through hole is provided on the protective shell, the through hole communicating with the first sliding groove; the fixing member can pass through the through hole and the first sliding groove in sequence and is provided in the fixing hole, so that the toothed ring is fixedly connected to the protective shell.

[0014] In one possible implementation, the first cup-retracting ring is provided with a second protrusion, and the toothed ring is provided with a third sliding groove corresponding to the second protrusion, and the second protrusion can slide in the third sliding groove.

[0015] Secondly, the present invention also provides a thromboelastography instrument, including a probe, a cup cap, and the aforementioned cup cap removal mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The cup-removing mechanism provided in this embodiment of the invention features a top tooth on a first cup-removing ring and a moving tooth on a second cup-removing ring. A first working groove is formed on the toothed ring to engage with the moving tooth. A bracket can drive the first cup-removing ring upwards. When the top tooth moves upwards, it engages with the moving tooth, causing the moving tooth to move above the first working groove. When the bracket moves downwards, the moving tooth above the first working groove moves downwards and inserts into the first working groove, causing the moving tooth to drive the top tooth downwards rapidly. As the first cup-removing ring moves downwards, it drives the cup cap downwards along the length of the probe until the cup cap separates from the probe. This cup-removing mechanism of the present invention can achieve automated separation of the cup cap and probe, thereby improving the efficiency of cup cap and probe separation and preventing operators from accidentally touching blood samples contaminated on the cup cap.

[0034] Example 1

[0035] Please see Figures 1 to 7 One embodiment of the present invention provides a cup-cap removal mechanism. The cup-cap removal mechanism is used in a thromboelastography instrument to automatically separate the probe 500 from the cup cap 600.

[0036] In this embodiment, the probe 500 and the cup cover 600 are both components of the thromboelastography instrument, and the probe 500 is connected to the cup cover 600 when it is working.

[0037] Please see Figure 1 and Figure 2 The cup-removing mechanism includes a toothed ring 200, a first cup-removing ring 300, a second cup-removing ring 400, and a bracket 700. The first cup-removing ring 300 is disposed inside the toothed ring 200 and is slidably connected to the toothed ring 200. The second cup-removing ring 400 is located above the toothed ring 200 and is movably disposed on the first cup-removing ring 300.

[0038] The probe 500 is inserted into the first cup-retracting ring 300, and the cup cover 600 is disposed within the first cup-retracting ring 300 and connected to the probe 500. The first cup-retracting ring 300 is provided with a top tooth 310, and the second cup-retracting ring 400 is provided with a moving tooth 410. The toothed ring 200 is provided with a first working groove 210 corresponding to the moving tooth 410. The bracket 700 can abut against the bottom of the first cup-retracting ring 300 to drive the first cup-retracting ring 300 to move upward. When the top tooth 310 moves upward, it can cooperate with the moving tooth 410, so that the moving tooth 410 moves above the first working groove 210.

[0039] When the bracket 700 moves downward, the moving tooth 410 above the first working groove 210 can be inserted into the first working groove 210, so that the moving tooth 410 drives the top tooth 310 to move downward, thereby causing the first cup retraction ring 300 to drive the cup cover 600 to move downward along the length direction of the probe 500 until the cup cover 600 is separated from the probe 500.

[0040] The cup-removing mechanism further includes a support plate 100 and a protective shell 110, which are fixedly connected by bolts. After the support plate 100 and the protective shell 110 are fixedly connected, a cavity 120 is formed inside. The toothed ring 200, the first cup-removing ring 300, and the second cup-removing ring 400 are all accommodated in the cavity 120. The toothed ring 200 is fixed in the cavity 120, and the first cup-removing ring 300 and the second cup-removing ring 400 can move within the cavity 120.

[0041] Combination Figure 3 and Figure 4 As shown, the cup-removing mechanism also includes a fixing member 260; the toothed ring 200 is fixedly connected to the protective shell 110 through the fixing member 260.

[0042] A fixing block 240 is provided on the outer side of the toothed ring 200, and a fixing hole 241 is provided on the fixing block 240; a first sliding groove 111 corresponding to the fixing block 240 is provided on the inner side of the protective shell 110, and a through hole 112 is provided on the protective shell 110, which communicates with the first sliding groove 111; the fixing block 240 is slidably disposed in the first sliding groove 111 so as to facilitate the connection between the toothed ring 200 and the protective shell 110.

[0043] The extending direction of the fixing block 240 on the toothed ring 200 is the same as the opening direction of the first sliding groove 111 on the protective shell 110, both being vertical.

[0044] The fastener 260 can pass through the through hole 112 and the first sliding groove 111 in the fixing hole 241 in sequence, so that the outer side of the toothed ring 200 is fixedly connected to the inner side of the protective shell 110.

[0045] The outer side of the toothed ring 200 is also provided with a first protrusion 250, and the inner side of the protective shell 110 is provided with a second sliding groove 113 corresponding to the first protrusion 250. The first protrusion 250 and the second sliding groove 113 are slidably connected. The extending direction of the first protrusion 250 on the toothed ring 200 and the opening direction of the second sliding groove 113 on the protective shell 110 are the same, both being vertical.

[0046] The first protrusion 250 cooperates with the second slide groove 113 to improve the accuracy of the position of the toothed ring 200 when it is fixed inside the protective shell 110.

[0047] The fixing block 240, the first protrusion 250 and the toothed ring 200 can be fixedly connected by integral molding.

[0048] In some embodiments, the toothed ring 200 may have a fixing block 240 and two first protrusions 250. The protective shell 110 has first sliding grooves 111 corresponding to the fixing block 240 and two second sliding grooves 113 corresponding to the two first protrusions 250. The two first protrusions 250 are symmetrically arranged on the toothed ring 200, and the fixing block 240 is disposed between the two first protrusions 250.

[0049] By setting two first protrusions 250 and two second sliding grooves 113 corresponding to the two first protrusions 250, the accuracy of the position of the toothed ring 200 when it is fixed inside the protective shell 110 can be further improved.

[0050] In other embodiments, the operator can adjust the position and number of the fixing block 240 and the first protrusion 250 on the toothed ring 200 as needed, thereby ensuring the accuracy and stability of the connection between the toothed ring 200 and the protective shell 110.

[0051] Please see Figures 3 to 5 The outer side of the first cup-retracting ring 300 is integrally formed with a second protrusion 320. The inner side of the first protrusion 250 has a third sliding groove 251 corresponding to the second protrusion 320, allowing the second protrusion 320 to slide within the third sliding groove 251. The extending direction of the second protrusion 320 on the first cup-retracting ring 300 is the same as the opening direction of the third sliding groove 251 on the first protrusion 250, both being vertical.

[0052] The upper width of the second protrusion 320 is greater than the lower width, and the shape of the third groove 251 matches the second protrusion 320. When the second protrusion 320 moves downward within the third groove 251, the greater width of the upper end of the second protrusion 320 than the lower end limits the downward movement distance of the second protrusion 320 within the third groove 251, thereby preventing the second protrusion 320 from sliding out of the third groove 251 when moving downward.

[0053] The first cup-retracting ring 300 is provided with a plurality of top teeth 310. The plurality of top teeth 310 are arranged at the upper end of the first cup-retracting ring 300 along the circumference of the first cup-retracting ring 300. The top teeth 310 are in the shape of an inverted V. When the first cup-retracting ring 300 moves upward, the top teeth 310 can act on the moving teeth 410 to drive the moving teeth 410 to move.

[0054] Combination Figure 6 As shown, a connecting post 330 is fixed inside the first cup-retracting ring 300, and the second cup-retracting ring 400 is located above the toothed ring 200 and is sleeved on the connecting post 330, and can move and rotate on the connecting post 330.

[0055] In some embodiments, a fixing plate is fixed to the inner side of the first cup-retracting ring 300, and the connecting post 330 is fixed above the fixing plate, thereby fixing the connecting post 330 to the first cup-retracting ring 300.

[0056] The cup-retracting mechanism also includes a retaining spring 340. A fixing groove 331 is provided on the connecting post 330, and the retaining spring 340 can be fixed within the fixing groove 331 to secure it to the connecting post 330. The fixing groove 331 is an annular groove, and the retaining spring 340 is an annular retaining spring; the shape of the fixing groove 331 matches the shape of the retaining spring 340.

[0057] The second cup-removing ring 400 is disposed between the top tooth 310 and the retaining spring 340. The retaining spring 340 can limit the upward movement distance of the second cup-removing ring 400, thereby preventing the second cup-removing ring 400 from falling off the connecting post 330 when it moves upward.

[0058] Combination Figure 7As shown, the second cup-retracting ring 400 is provided with a plurality of moving teeth 410, which are arranged at intervals along the circumference of the second cup-retracting ring 400 on the outer side of the second cup-retracting ring 400. The toothed ring 200 is provided with a plurality of first working grooves 210, which correspond one-to-one with the plurality of moving teeth 410.

[0059] In some embodiments, the extending direction of the movable tooth 410 on the second cup retraction ring 400 is the same as the opening direction of the first working groove 210 on the toothed ring 200, and both are vertical, so that the movable tooth 410 can be inserted into the first working groove 210.

[0060] The lower end of the movable tooth 410 is provided with an inclined surface 411 that engages with the top tooth 310. When the bracket 700 drives the first cup-retracting ring 300 to move upward, the top tooth 310 can act on the inclined surface 411, so that the top tooth 310 can drive the movable tooth 410 to move upward and rotate along the circumferential direction of the connecting column 330, thereby moving the movable tooth 410 above the first working groove 210.

[0061] Please see Figure 1 and Figure 2 The probe 500 is a component of the thromboelastography instrument for measuring blood sample data, and the upper end of the probe 500 is fixedly connected to the vertical suspension wire on the thromboelastography instrument.

[0062] The lower end of the first cup-removing ring 300 has a cavity. The probe 500 passes through the support plate 100, the cavity 120 and the connecting post 330 in sequence and is located in the cavity of the first cup-removing ring 300. When it is necessary to separate the cup cover 600 from the probe 500, the cup cover 600 is located in the cavity and is sleeved on the lower end of the probe 500.

[0063] The connecting post 330 has a mating hole that communicates with the cavity. The lower end of the probe 500 passes through the mating hole and is located within the cavity. The cup lid 600 is located within the cavity and is connected to the probe 500. The diameter of the mating hole is smaller than the diameter of the cup lid 600. When the first cup retraction ring 300 moves downward, the inner wall of the cavity can abut against the cup lid 600, thereby causing the cup lid 600 to move downward until it separates from the probe 500.

[0064] The probe 500 and the cup lid 600 are fixedly connected by an interference fit. The cup lid 600 has a connection hole that mates with the probe 500. A fixing strip is provided on the inner wall of the connection hole. When the probe 500 is inserted into the connection hole, the fixing strip mates with the probe 500 to make the probe 500 and the connection hole an interference fit connection, thereby connecting the probe 500 and the cup lid 600.

[0065] The cup-removing mechanism also includes a cup body 610, and the bracket 700 is used to support the cup body 610. The cup lid 600 can be disposed on the cup body 610 so that the probe 500 can drive the cup lid 600 to rotate within the cup body 610, so that the probe 500 can measure the data of the blood sample in the cup body 610.

[0066] The bracket 700 is provided with an adapter 710, and the cup body 610 is fixed in the adapter 710 by an interference fit, so that the cup body 610 is fixedly connected to the bracket 700.

[0067] The cup-removing mechanism also includes a moving component (not shown), which drives the bracket 700 to move so that the bracket 700 moves the first cup-removing ring 300, thereby moving the moving tooth 410 above the first working groove 210.

[0068] When the moving component drives the bracket 700 to move downward, the moving tooth 410 located above the first working groove 210 can move downward and insert into the first working groove 210. When the moving tooth 410 moves downward, it can exert pressure on the top tooth 310, thereby causing the first cup retraction ring 300 to move downward. Since the cup cover 600 is located in the cavity of the first cup retraction ring 300, when the first cup retraction ring 300 moves downward, it can drive the cup cover 600 on the probe 500 to move downward along the length direction of the probe 500, so that the cup cover 600 separates from the probe 500 and falls onto the cup body 610.

[0069] Please see Figures 4 to 7 The toothed ring 200 is further provided with a second working groove 220 corresponding to the moving tooth 410, and the lower end of the moving tooth 410 can be inserted into the second working groove 220. The vertical depth of the second working groove 220 is less than the vertical depth of the first working groove 210, and the shape of the second working groove 220 matches the shape of the inclined surface 411.

[0070] Since the shape of the second working groove 220 matches the shape of the inclined surface 411, even if there is a certain positional deviation when the moving tooth 410 moves downward to insert into the second working groove 220, the lower end of the moving tooth 410 can still slide correctly into the second working groove 220.

[0071] The toothed ring 200 is provided with a plurality of first working grooves 210 and a plurality of second working grooves 220, which are distributed sequentially at intervals on the toothed ring 200.

[0072] The second working groove 220 communicates with the third sliding groove 251, so that the second protrusion 320 can enter the third sliding groove 251 through the second working groove 220. However, it is worth noting that the width of the third sliding groove 251 is smaller than the width of the moving tooth 410. When the lower end of the moving tooth 410 moves downward, the lower end of the moving tooth 410 will not enter the third sliding groove 251 through the second working groove 220.

[0073] In some embodiments, an inclined portion 230 is provided between the first working groove 210 and the second working groove 220. The inclined portion 230 has a lower height on the side closer to the first working groove 210 and a higher inclination on the side closer to the second working groove 220. The inclination direction of the inclined surface 411 matches the inclination direction of the inclined portion 230, and the height of the inclined surface 411 on the moving tooth 410 gradually increases from left to right.

[0074] The inclined portion 230 cooperates with the inclined surface 411. When the inclined surface 411 falls onto the inclined portion 230, the inclined portion 230 can act as a guide so that the moving tooth 410 slides into the first working groove 210. Thus, even if the moving tooth 410 is not directly above the first working groove 210 when it falls, the moving tooth 410 can still be correctly inserted into the corresponding first working groove 210.

[0075] In some embodiments, the cup-removing mechanism further includes a spring 800 disposed within the cavity 120, with one end of the spring 800 abutting against the inner side of the support plate 100 and the other end abutting against the upper end of the second cup-removing ring 400. When the support 700 drives the first cup-removing ring 300 upward, the top tooth 310 on the first cup-removing ring 300 drives the moving tooth 410 on the second cup-removing ring 400 upward, thereby causing the second cup-removing ring 400 to move upward and compress the spring 800; when the support 700 moves downward, the spring 800 can extend, and the elastic force of the spring 800 increases the downward movement speed of the second cup-removing ring 400, thereby increasing the speed at which the moving tooth 410 inserts into the first working groove 210, so that the first cup-removing ring 300 moves downward quickly while simultaneously causing the cup lid 600 to separate from the probe 500.

[0076] In some embodiments, before the cup lid ejection mechanism is used, the moving tooth 410 is inserted into the first working groove 210, the cup lid 600 is fixed on the probe 500, the moving component drives the bracket 700 to move upward, the bracket 700 drives the cup body 610 to move upward, so that the cup lid 600 can be inserted into the cup body 610, and the probe 500 can drive the cup lid 600 to rotate within the cup body 610.

[0077] The bracket 700 drives the first cup-retracting ring 300 to move upward continuously, so that when the top tooth 310 on the first cup-retracting ring 300 moves upward, it can act on the inclined surface 411, so that the moving tooth 410 moves upward in the first working groove 210. When the moving tooth 410 moves upward to a certain height, the moving tooth 410 can rotate around the circumference of the connecting column 330 under the action of the top tooth 310, so that the moving tooth 410 can move above the second working groove 220.

[0078] After the moving tooth 410 is positioned above the second working groove 220, the moving component can drive the bracket 700 to move downward to the first working position. At this time, under the action of gravity and the elastic force of the spring 800, the moving tooth 410 can be inserted into the second working groove 220. Since the depth of the second working groove 220 is relatively shallow, the first cup-removing ring 300 moves downward a short distance. When the moving tooth 410 falls in the second working groove 220, the first cup-removing ring 300 will not press down on the cup cover 600 on the probe 500.

[0079] When the bracket 700 is in the first working position, the moving tooth 410 is inserted into the second working groove 220, the cup lid 600 is just placed on the cup body 610, and the probe 500 can drive the cup lid 600 to rotate in the cup body 610, so that the probe 500 measures the data of the blood sample in the cup body 610.

[0080] When the probe 500 finishes measuring the blood sample data and needs to be separated from the cup lid 600, the moving component can drive the bracket 700 to move upward from the first work station, so that the moving tooth 410 moves upward in the second working groove 220. When the moving tooth 410 moves upward to a certain height, the moving tooth 410 can rotate circumferentially along the connecting column 330 under the action of the top tooth 310, so that the moving tooth 410 can move above the first working groove 210.

[0081] After the moving tooth 410 is positioned above the first working groove 210, the moving component drives the bracket 700 to move downward to the second working position. The height of the second working position is lower than the height of the first working position. Under the action of gravity and the elastic force of the spring 800, the moving tooth 410 can be inserted into the first working groove 210. Since the first working groove 210 is relatively deep and the first cup retraction ring 300 moves downward a long distance, when the moving tooth 410 drives the top tooth 310 to move downward, the first cup retraction ring 300 can drive the cup cover 600 to move downward along the length direction of the probe 500 until the cup cover 600 separates from the probe 500 and falls onto the cup body 610.

[0082] In some embodiments, when the upper end of the bracket 700 abuts against the lower end of the protective shell 110, the moving tooth 410 moves from the second working groove 220 to above the first working groove 210, or from the first working groove 210 to above the second working groove 220.

[0083] The cup-removing mechanism described in this embodiment features a top tooth 310 on the first cup-removing ring 300, a moving tooth 410 on the second cup-removing ring 400, and a first working groove 210 on the toothed ring 200 that engages with the moving tooth 410. The bracket 700 can drive the first cup-removing ring 300 to move upward. When the top tooth 310 moves upward, it engages with the moving tooth 410, causing the moving tooth 410 to move above the first working groove 210. When the bracket 700 moves downward, the moving tooth 410 above the first working groove 210 can move downward and insert into the first working groove 210, causing the moving tooth 410 to drive the top tooth 310 to move downward quickly. When the first cup-removing ring 300 moves downward, it can drive the cup lid 600 to move downward along the length of the probe 500 until the cup lid 600 separates from the probe 500. The cup lid removal mechanism of the present invention can realize the automatic separation of the cup lid 600 and the probe 500, thereby improving the efficiency of the separation of the cup lid 600 and the probe 500, and can also prevent the operator from accidentally touching the blood sample on the cup lid 600.

[0084] Example 2

[0085] The present invention also provides a thromboelastography instrument, which includes a probe 500, a cup cover 600 and the aforementioned cup cover retraction mechanism. The probe 500 is inserted into the first cup retraction ring 300, and the cup cover 600 is disposed in the first cup retraction ring 300 and connected to the probe 500.

[0086] When the thromboelastography instrument is working, the cup lid 600 can be placed on the cup body 610, and the probe 500 can drive the cup lid 600 to rotate coaxially within the cup body 610. The viscoelastic force of the blood sample in the cup body 610 during coagulation can change the rotation amplitude of the cup lid 600, thereby changing the rotation amplitude of the probe 500. By measuring the change in the rotation amplitude of the probe 500, the change in blood viscoelastic force can be accurately reflected, thereby drawing an accurate thromboelastography map.

[0087] The cup lid removal mechanism is used to automatically separate the probe 500 from the cup lid 600 after the probe 500 has measured the blood sample data.
