Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a transmission device and an in vitro diagnostic device. Background Art

[0002] At present, in vitro diagnosis is one of the most commonly used diagnostic methods in the medical field. According to the detection principle or detection method, in vitro diagnosis is mainly divided into biochemical diagnosis, immunological diagnosis, molecular diagnosis, microbiological diagnosis, urine diagnosis, coagulation diagnosis, blood and flow cytometric diagnosis, etc. In order to improve the detection efficiency, it is necessary to use fully automatic or semi-automatic in vitro diagnostic equipment for the above diagnosis.

[0003] Since the above diagnostic process involves sampling steps and / or stirring steps, in order to improve the automation level of the in vitro diagnostic equipment, a transmission device is required to drive the sampling device and / or stirring device to move to complete the corresponding sampling and / or stirring.

[0004] However, the structure of the traditional transmission device is relatively complex and the assembly efficiency is low, which is not conducive to reducing the cost of in vitro diagnostic equipment. Summary of the invention

[0005] Based on this, it is necessary to provide a transmission device and an in vitro diagnostic device. The transmission device is easy to modularize and is conducive to improving assembly efficiency; and is applied to in vitro diagnostic devices, which is conducive to reducing the cost of in vitro diagnostic devices.

[0006] The technical solution is as follows:

[0007] In the first aspect, the present application provides a transmission device, including an installation component, a transmission component, a first drive mechanism and a second drive mechanism; the installation component includes a support member and a mounting member, the support member is fixedly connected to the mounting member to support the mounting member, and the mounting member is provided with a first mounting through hole; the transmission component includes a transmission sleeve and a transmission shaft sleeved with the transmission sleeve, the transmission sleeve is inserted in the first mounting through hole and can be rotatably arranged on the mounting member, the transmission sleeve drives the transmission shaft to rotate, and the transmission shaft can slide relative to the length direction of the transmission sleeve; the first drive mechanism is arranged on the installation component, and is used to drive the transmission sleeve to rotate; the second drive mechanism is arranged on the installation component, and the second drive mechanism includes a telescopic end, the telescopic end is slidably matched with the support member, and is rotatably connected to the transmission shaft, and the telescopic end drives the transmission shaft to slide reciprocatingly along the length direction of the transmission sleeve.

When in use, the first driving mechanism drives the transmission shaft to rotate through the transmission sleeve, and the second driving mechanism drives the transmission shaft to reciprocate along the length direction of the transmission sleeve (that is, the axial direction of the transmission shaft) through the telescopic end, so that the transmission shaft can be used to realize the rotation and lifting movement required for sampling or stirring.

[0035] BRIEF DESCRIPTION OF THE DRAWINGS The drawings constituting a part of the present application are used to provide a further understanding of the present application. The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation on the present application.

[0036] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain this application and do not limit the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0039] In order to improve the diagnostic efficiency and simplify the process of manual intervention, the sampling steps and / or stirring steps of in vitro diagnostic equipment are generally implemented through related structures. Since the sampling process involves transporting the sampling needle to several locations such as the sample cup (reagent bottle), reaction cup, and cleaning sink to complete the processes of sample suction, sample discharge, and cleaning; and / or transporting the stirring paddle to several locations such as the reaction cup and the cleaning sink to complete the stirring and cleaning processes, the transmission device for sampling or stirring needs to control the output lifting power and rotational power, and the overall transmission structure is relatively complex, resulting in low assembly efficiency of the transmission device; at the same time, the overall volume of the transmission device is large, which is not conducive to reducing the cost of in vitro diagnostic equipment, nor is it conducive to miniaturization.

[0040] The present application provides a transmission device that is easy to assemble in a modular manner through structural optimization, which is beneficial to improving the assembly efficiency of the transmission device of the present application, thereby reducing the production cost of the transmission device of the present application. At the same time, the installation structure is fully utilized for guidance, making the overall structure more compact and smaller in size, which can meet the needs of miniaturization development of in vitro diagnostic equipment.

[0041] The following describes the method in conjunction with specific embodiments.

[0042] like Figures 1 to 5 FIG. 1 is a structural view of a transmission device 10 in one embodiment. Figure 1 FIG. 1 is a schematic structural diagram of a transmission device 10 shown in an embodiment. Figure 2 for Figure 1 The schematic cross-sectional view of the local structure of the transmission device 10 is shown. Figure 3 for Figure 1 A partial enlarged schematic diagram shown. Figure 4 for Figure 1 A schematic top view of the transmission device 10 is shown. Figure 5 for Figure 1 The structure diagram of the transmission device 10 shown is from another perspective.

[0043] In this embodiment, the transmission device 10 includes a mounting assembly 100, a transmission assembly 200, a first driving mechanism 300 and a second driving mechanism 400. The mounting assembly 100 includes a support member 110 and a mounting member 120. The support member 110 is fixedly connected to the mounting member 120 to support the mounting member 120. The mounting member 120 is provided with a first mounting through hole 122. The transmission assembly 200 includes a transmission sleeve 210 and a transmission shaft 220 sleeved with the transmission sleeve 210. The transmission sleeve 210 is inserted into the first mounting through hole 122 and can be rotatably arranged on the mounting member 120. The transmission sleeve 210 drives the transmission shaft 220 to rotate, and the transmission shaft 220 can slide relative to the length direction of the transmission sleeve 210. The first driving mechanism 300 is arranged on the mounting assembly 100, and is used to drive the transmission sleeve 210 to rotate. The second driving mechanism 400 is disposed on the mounting assembly 100 , and includes a telescopic end 410 , which is slidably matched with the support member 110 and is rotationally connected to the transmission shaft 220 , and the telescopic end 410 drives the transmission shaft 220 to slide back and forth along the length direction of the transmission sleeve 210 .

[0044] When the transmission device 10 is assembled, the support member 110 is fully utilized to limit the telescopic end 410 to move back and forth only in a preset direction, and will not rotate with the transmission shaft 220, thereby simplifying the limiting structure of the telescopic end 410, making the overall structure more compact and smaller in size. At the same time, the transmission shaft 220 will not drive the telescopic end 410 to rotate, thereby reliably maintaining the telescopic position of the transmission shaft 220, and the transmission shaft 220 and the transmission sleeve 210 can be assembled into a module, and then assembled on the mounting member 120 through the transmission sleeve 210, so as to realize the rotation and telescopic sliding of the transmission shaft 220. That is, the mounting assembly 100, the transmission assembly 200, the first drive mechanism 300 and the second drive mechanism 400 can be respectively assembled into a module first, and then modularly assembled into the transmission device 10, thereby improving the assembly efficiency.

[0045] When the transmission device 10 is used, the support 110 is used to fix the transmission device 10 in the in vitro diagnostic device, the first driving mechanism 300 drives the transmission shaft 220 to rotate through the transmission sleeve 210, and the second driving mechanism 400 drives the transmission shaft 220 to reciprocate along the length direction of the transmission sleeve 210 (that is, the axial direction of the transmission shaft 220) through the telescopic end 410, so that the transmission shaft 220 can be used to achieve the rotation and lifting movement required for sampling or stirring. In this way, the transmission device 10 of the present application is easy to modularize through structural optimization, which is conducive to improving the assembly efficiency of the transmission device 10 of the present application, and thus can reduce the production cost of the transmission device 10 of the present application.

[0046] It should be noted that the first driving mechanism 300 includes power equipment such as a servo motor and a rotary hydraulic cylinder that directly drives the transmission sleeve 210 to rotate, and also includes other mechanisms that indirectly drive the transmission sleeve 210 to rotate, such as a pneumatic rod + gear rack assembly, a hydraulic rod + crank rocker assembly or a crank slider assembly, a servo motor + a reduction box, and a servo motor + a flexible transmission assembly. All of the above can be implemented in traditional technologies and will not be described in detail here.

[0047] Similarly, the second driving mechanism 400 includes but is not limited to power equipment such as telescopic sticks, telescopic plates, telescopic rods, pneumatic rods, hydraulic rods, linear motors, etc. that directly drive the lifting and lowering movement of the transmission shaft 220, and also includes mechanisms that indirectly realize the lifting and lowering movement of the transmission shaft 220 using gear rack assemblies + servo motors, screw nut assemblies + servo motors, flexible transmission assemblies 200 + servo motors, etc.

[0048] like Figure 5 As shown, in an exemplary embodiment, the second driving mechanism 400 includes a flexible transmission assembly 200 and a servo motor. The flexible transmission assembly 200 includes a second flexible member 420. The telescopic end 410 is fixed to the flexible member and moves up and down with the flexible member.

[0049] The flexible member includes but is not limited to a traction rope, a belt, a chain, a track, etc.

[0050] It should be noted that there can be many ways to rotationally connect the "drive shaft 220" and the "telescopic end 410", including but not limited to the use of bearing connection, hinge, shaft matching + limit structure, etc., which can achieve rotational connection but cannot slide along the drive shaft 220.

[0051] It should be noted that the "installing part 120" can be one of the parts of the module "installing component 100", that is, it can be assembled separately from the "other components of the installing component 100" to facilitate modular assembly; it can also be manufactured relatively independently from the "other components of the installing component 100", and installed independently, that is, it can be assembled with the "other components of the installing component 100" in this device.

[0052] Equivalently, the components included in the "assembly", "mechanism" and "device" of this application can also be flexibly combined, that is, modular production can be carried out according to actual needs to facilitate modular assembly. The division of the above components in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of this application.

[0053] Based on any of the above embodiments, in some embodiments, the transmission sleeve 210 is provided with a non-circular hole 212, and the transmission shaft 220 is adapted to the non-circular hole 212. In this way, the transmission shaft 220 can rotate with the transmission sleeve 210 and can slide relative to the transmission sleeve 210 by using the non-circular hole 212 and the non-circular transmission shaft 220.

[0054] The non-circular hole 212 includes various special-shaped holes, such as a partial circular hole (semicircle, 2 / 3 circle, etc.), an elliptical hole, a polygonal hole, a cam-shaped hole, etc.

[0055] Based on any of the above embodiments, Figure 2 As shown, in some embodiments, the mounting assembly 100 includes a rotating sleeve 130, which is inserted into the first mounting through hole 122 and is rotatably connected to the mounting member 120, and the rotating sleeve 130 is fixedly connected to the transmission sleeve 210. In this way, when the mounting assembly 100 is assembled, the rotating sleeve 130 can be used to form a rotating connection portion, which is convenient for fixed connection with the transmission sleeve 210, so that the transmission sleeve 210 can be rotatably set on the mounting member 120, which is conducive to improving the installation accuracy of the transmission sleeve 210.

[0056] It should be noted that the specific implementation of the rotating sleeve 130 includes but is not limited to a rolling bearing, a sliding bearing or a connecting sleeve.

[0057] There are also many ways to fix the rotating sleeve 130 and the transmission sleeve 210, including but not limited to screw connection, clamping connection, welding, etc.

[0058] In some exemplary embodiments, key blocks or positioning pins are used for auxiliary fixation.

[0059] Based on the above embodiments, Figure 5 As shown, in some embodiments, the first driving mechanism 300 further includes a driving wheel 310, a driven wheel 320 and a first motor 330. The driving wheel 310 and the driven wheel 320 are rotatably disposed on the mounting member 120. The driving wheel 310 drives the driven wheel 320 to rotate. The driven wheel 320 is coaxially rotatably connected with the rotating sleeve 130, and the first motor 330 drives the driving wheel 310 to rotate. In this way, the first motor 330 cooperates with the driving wheel 310 and the driven wheel 320 to indirectly drive the rotating sleeve 130 to rotate; and the transmission distance between the driving wheel 310 and the driven wheel 320 can be flexibly adjusted, so that the first motor 330 can be flexibly set to facilitate avoidance.

[0060] In some exemplary embodiments, the driving wheel 310 and the driven wheel 320 are both gears, and the two can cooperate to form a gear transmission structure.

[0061] Or, in some exemplary embodiments, the driving wheel 310 and the driven wheel 320 realize transmission cooperation through the first flexible member 340, and can form a flexible transmission structure, such as a belt transmission structure, a chain transmission structure, and the like.

[0062] Based on any of the above embodiments of the driven wheel 320, Figure 2 and Figure 5 As shown, in some embodiments, the rotating sleeve 130 includes a first sleeve body 132 fixedly connected to the transmission sleeve 210 and a second sleeve body 134 fixedly connected to the driven wheel 320, the first sleeve body 132 is installed in the first mounting through hole 122 through a bearing, and the second sleeve body 134 is protruded from the first mounting through hole 122. In this way, two rotating connection parts are formed by using the rotating sleeve 130 in the mounting assembly 100, that is, the first sleeve body 132 is fixedly connected to the transmission sleeve 210, and the second sleeve body 134 is fixedly connected to the driven wheel 320, which can be assembled with the transmission assembly 200 and the first driving mechanism 300 respectively, which is conducive to further improving the assembly efficiency and assembly accuracy, and realizing that the driven wheel 320 indirectly drives the transmission sleeve 210 to rotate.

[0063] In addition, the outer surface of the first sleeve 132 is fixedly connected to the inner ring of the bearing, and can be manufactured more precisely to improve the connection accuracy and reduce the rotation error of the transmission shaft 220.

[0064] Based on any of the above embodiments, Figure 1 , Figures 3 to 5 As shown, in some embodiments, the transmission assembly 200 further includes a limiter 230 that rotates with the transmission sleeve 210, the limiter 230 is provided with a first limiter 232, the mounting member 120 is provided with a second limiter 124, and the second limiter 124 is limitedly matched with the first limiter 232 to limit the rotation range of the transmission sleeve 210. In this way, the limiter 230 is directly or indirectly fixed on the transmission sleeve 210, so that the limiter 230 rotates with the transmission sleeve 210, and the first limiter 232 cooperates with the second limiter 124, so that the transmission sleeve 210 rotates within a certain rotation range, thereby improving the transmission safety and preventing the sampling needle 32 or the stirring paddle 42 from causing equipment damage or operator damage due to a malfunction.

[0065] There can be many specific implementation methods of the first limiting portion 232 and the second limiting portion 124, such as an arc rail and an arc block, an arc groove and a limiting body arranged in the groove, or the first limiting portion 232 includes two limiting ends arranged at intervals, and the second limiting portion 124 includes a stop body that cooperates with the limiting end to stop rotation.

[0066] Based on the above embodiments, Figure 4As shown, in some embodiments, one of the first limiting portion 232 and the second limiting portion 124 is an arc groove, and the other is a convex body, and the convex body is partially disposed in the arc groove. In this way, the rotation range of the transmission sleeve 210 is limited by the cooperation between the arc groove and the convex body, and the length of the arc groove can be adjusted according to different rotation angles, which is easy to adjust and can meet the restrictions of different rotation angles.

[0067] In one exemplary embodiment, the arc-shaped groove is in the shape of a notch.

[0068] On the basis of the above embodiments, in some embodiments, the transmission sleeve 210 is in the shape of a circular cylinder, and the limiting member 230 is further provided with a second through hole 234 adapted to the transmission sleeve 210 and an arc-shaped notch 236 connected to the second through hole 234, and the arc-shaped notch is clearance-matched with the transmission shaft 220 and is locked with the transmission sleeve 210. In this way, the limiting member 230 can be installed and replaced separately. For example, during installation, the limiting member 230 passes through the arc-shaped notch 236 so that the second through hole 234 is inserted into the transmission shaft 220, and then the limiting member 230 is moved downward so that the second through hole 234 is adapted to the traditional sleeve, so that the arc-shaped notch 236 is locked with the transmission sleeve 210, so that the limiting member 230 is locked in the transmission sleeve 210, and then the limiting member 230 is fixed to the transmission sleeve 210 by a fixing member. During replacement, after the limiting member 230 moves away from the transmission sleeve 210 , the arc-shaped notch 236 and the transmission shaft 220 are in clearance fit, so that the limiting member 230 can be pulled out of the transmission shaft 220 from the side to achieve separation.

[0069] In combination with the above-mentioned embodiments, in some embodiments, the arc groove is in the shape of a notch, and the width of the notch of the arc groove is greater than the diameter of the transmission shaft 220; the arc notch 236 connects the arc groove and the second through hole 234. In this way, the stopper 230 can be installed and replaced separately. For example, during installation, the stopper 230 is inserted into the transmission shaft 220 through the arc groove and the arc notch 236, and then the stopper 230 is moved down so that the second through hole 234 is adapted to the traditional sleeve. Since the width of the arc notch 236 is smaller than the outer diameter of the transmission sleeve 210, the stopper 230 is clamped in the transmission sleeve 210, and then the stopper 230 is fixed to the transmission sleeve 210 by a fixing member. During replacement, after the stopper 230 moves away from the transmission sleeve 210, since the width of the arc notch 236 is greater than the diameter of the transmission shaft 220, the stopper 230 can be pulled out of the transmission shaft 220 from the side to achieve separation.

[0070] In an exemplary embodiment, the limiting member 230 is fixed to the end of the rotating sleeve 130 by a fixing member (such as a fixing pin, a fastening bolt, a fastening screw, a clamp, etc.).

[0071] It should be noted that the "convex body" can be "a part of the mounting member 120", that is, the "convex body" and the "other parts of the mounting member 120" are manufactured as one piece; it can also be an independent component that can be detached from the "other parts of the mounting member 120", that is, the "convex body" can be manufactured independently and then combined with the "other parts of the mounting member 120" into a whole.

[0072] In an exemplary embodiment, the protrusion is a bolt, which is fixed on the rotating sleeve 130 and partially disposed in the arc groove.

[0073] Equivalently, "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; or it can be an independent component that can be detached from the "other parts of the component", that is, "some body" or "some part" can be independently manufactured and then combined with the "other parts of the component" into a whole. The expression of the above-mentioned "some body" or "some part" in this application is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this application. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this application.

[0074] Based on any of the above embodiments, Figure 3 As shown, in some embodiments, the transmission device 10 further includes a first position detection assembly 500 mounted on the mounting member 120, and the limiter 230 is provided with a triggering portion 238 that triggers and cooperates with the first position detection assembly 500, and the triggering portion 238 is staggered with the first limiter 232. Furthermore, through the cooperation between the first position detection assembly 500 and the triggering portion 238, the rotation angle of the transmission sleeve 210 can be indirectly detected, which is convenient for calibration and / or detection of the rotation angle of the transmission shaft 220. At the same time, the limiter 230 integrates the limit function and the position recognition function, which is conducive to further simplifying the parts, making the structure of the transmission device 10 of the present application simpler, reducing the cost of parts, and further improving the assembly efficiency.

[0075] As an example, the first position detection component 500 is connected to the controller 20 for communication to achieve calibration and rotation angle control of the transmission shaft 220 .

[0076] The specific implementation of the first position detection component 500 includes but is not limited to a magnetic displacement sensor, a pressure sensor, a photoelectric sensor or a machine vision sensor.
