Abstract

The utility model relates to a reagent detection device. A shell of the reagent detection device is provided with an insertion hole for inserting a reagent disc; the tray is rotatably arranged in the shell; the two synchronous belt assemblies are arranged in the shell and located on the two sides of the tray correspondingly. The elastic tensioning assemblies are arranged in the shell and arranged above the synchronous belt assembly at intervals. When the reagent disc is inserted into the insertion hole, the elastic tensioning assembly elastically abuts against the top of the reagent disc so that the two sides of the bottom of the reagent disc can be pressed on the two synchronous belt assemblies respectively, and the two synchronous belt assemblies can convey the reagent disc to the position above the tray; when the reagent discs are conveyed to the position above the tray, the pressing assembly can descend in the height direction of the shell and synchronously press the two synchronous belt assemblies downwards, the reagent discs borne on the synchronous belt assemblies descend together, and therefore the tops of the reagent discs are separated from the elastic tensioning assembly till the reagent discs are fixed to the tray through the pressing assembly. And the bottom of the reagent disc is separated from the two synchronous belt assemblies.

Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a reagent detection device. Background Art

[0002] Traditional reagent testing devices use drawer-type and flip-top types for loading reagent trays. The flip-top type reagent testing device requires space to be reserved above the instrument when flipping the cover, which is not suitable for use in vehicle-mounted scenarios such as ambulances where space is limited and there are many items stacked. Therefore, drawer-type reagent testing devices are generally used in vehicle-mounted environments.

[0003] However, in the process of loading the reagent tray into the drawer-type reagent testing device, the reagent tray has freedom, and the instrument must be placed on a stationary table, otherwise it is very easy to shift the position. In the vehicle-mounted scenario, it is difficult to avoid road bumps during driving and the vehicle itself will also vibrate. Therefore, when loading the reagent tray into the traditional drawer-type reagent testing device in this type of environment, the risk of displacement of the reagent tray during loading is extremely high.

[0004] Therefore, there is an urgent need to provide a reagent detection device that can adapt to most usage environments and achieve stable loading of the reagent disc.

[0005] BACKGROUND OF THE PRESENT INVENTION The above information disclosed is only used to understand the background of the concept of the present invention and may contain information that does not constitute prior art. Utility Model Content

[0006] Based on this, it is necessary to provide a reagent detection device to address the above problems.

[0007] A reagent detection device, comprising:

[0008] A housing, wherein the housing is provided with an insertion hole for inserting the reagent disk;

[0009] a tray, the tray being rotatably disposed in the housing;

[0010] Two synchronous belt assemblies, the two synchronous belt assemblies are arranged in the housing and are respectively located on both sides of the tray, and the length extension direction of the synchronous belt assembly is parallel to the axial direction of the insertion hole;

[0011] An elastic tensioning assembly, the elastic tensioning assembly is arranged in the housing and is spaced above the synchronous belt assembly;

[0012] A clamping assembly, which is disposed on the housing and can move up and down along the height direction of the housing to approach or move away from the tray;

[0013] Wherein, when the reagent tray is inserted into the insertion hole, the elastic tensioning assembly elastically abuts against the top of the reagent tray so that the two sides of the bottom of the reagent tray are respectively pressed against the two synchronous belt assemblies, and the two synchronous belt assemblies can transport the reagent tray to the top of the tray;

[0014] When the reagent tray is transferred to the top of the tray, the clamping assembly can descend along the height direction of the shell and synchronously press down the two synchronous belt assemblies, and make the reagent tray carried by the synchronous belt assembly descend together, so that the top of the reagent tray is separated from the elastic tensioning assembly, until the clamping assembly fixes the reagent tray on the tray and the bottom of the reagent tray is separated from the two synchronous belt assemblies.

[0015] The reagent detection device of the utility model can at least achieve the following beneficial effects: when the reagent tray is inserted into the housing from the insertion hole, the reagent tray will be clamped between the elastic tensioning assembly and the synchronous belt assembly, and then the synchronous belt assembly can transfer the reagent tray to the top of the tray, the pressing assembly descends and presses down the synchronous belt assembly, the synchronous belt assembly is pressed downward and concave, and the reagent tray on the synchronous belt assembly will also descend together, and the descending distance exceeds the movement stroke of the elastic tensioning assembly, so the top of the reagent tray will be separated from the elastic tensioning assembly. When the reagent tray descends to the tray, the synchronous belt assembly can be pressed down by the pressing assembly, and the bottom of the reagent tray is also separated from the synchronous belt assembly, and the reagent tray is also pressed and fixed on the tray by the pressing assembly, and the tray can drive the reagent tray to rotate for detection. It should be emphasized that during the loading process, the reagent tray is clamped between the elastic tensioning assembly and the synchronous belt assembly, and the movement of the reagent tray can be limited by friction, thereby preventing the reagent tray from being displaced in the shell after insertion, ensuring that the reagent tray can be accurately transferred to the top of the tray. Therefore, the reagent detection device of the present application has higher adaptability, and the reagent tray loading process is very stable, and can be applied to special environments such as vehicle environments.

[0016] In one embodiment, the number of the elastic tensioning components is set to two, and each of the elastic tensioning components is arranged above a synchronous belt component at intervals; when the reagent tray is inserted into the insertion hole, one side of the reagent tray can be elastically abutted between one synchronous belt component and one elastic tensioning component, and the other side of the reagent tray can be elastically abutted between another synchronous belt component and another elastic tensioning component. During the loading process of the reagent tray, both sides of the reagent tray are clamped between the elastic tensioning component and the synchronous belt component. Such a structural setting can further improve the stability of the reagent tray during loading, and what is clamped is the edge of the reagent tray, which will not affect the main structure in the middle of the reagent tray, such as avoiding the liquid capsule and valve on the reagent tray, thereby ensuring the integrity and effectiveness of the reagent tray.

[0017] In one embodiment, the elastic tensioning assembly includes a bracket, a rolling element and an elastic element, one end of the elastic element is connected to the housing, the other end of the elastic element is connected to the side of the bracket facing away from the synchronous belt assembly, and the rolling element is rotatably connected to the side of the bracket facing the synchronous belt assembly; when the reagent tray is inserted into the insertion hole, the rolling element abuts against the top of the reagent tray and can press the reagent tray on the top of the synchronous belt under the elastic force of the elastic element, and the rolling element can roll on the top of the reagent tray when the synchronous belt assembly drives the reagent tray to move. When the reagent tray is loaded, the reagent tray is elastically clamped between the elastic tensioning assembly and the synchronous belt assembly, even if the thickness of different reagent trays is different, the elastic element can be adaptively compressed so that the rolling element is always close to the top of the reagent tray, which can avoid the elastic tensioning assembly from exerting too much pressure on the reagent tray and damaging the structure of the reagent tray.

[0018] In one embodiment, the number of the rolling elements is set to be multiple, and the multiple rolling elements are arranged at intervals along the length extension direction of the bracket, and the length extension direction of the bracket is parallel to the synchronous belt assembly. The rolling element can be a roller or a ball. Increasing the number of rolling elements and arranging them along the transmission direction of the synchronous belt assembly can increase their contact points with the reagent disc, and they are consistent with the direction in which the reagent disc is transmitted, which is conducive to further improving the stability of the reagent disc loading process.

[0019] In one embodiment, the clamping assembly includes a pressure head capable of performing lifting and lowering motion along the height direction of the shell and a pressure plate connected to the pressure head, and the pressure plate is provided with four pressing parts, wherein two of the pressing parts are located above one of the synchronous belt assemblies and are arranged at intervals, and the other two of the pressing parts are located above another of the synchronous belt assemblies and are arranged at intervals; when the reagent disc is transferred to the top of the tray, the clamping assembly can descend along the height direction of the shell, and the two pressing parts avoid the reagent disc and abut against the two ends of one of the synchronous belt assemblies, and the other two pressing parts avoid the reagent disc and abut against the two ends of the other synchronous belt assemblies, so that the two synchronous belt assemblies are partially recessed and the reagent disc is lowered to abut against the tray until the pressure head fixes the reagent disc on the tray and the bottom of the reagent disc is separated from the two synchronous belt assemblies.

[0020] In one embodiment, the clamping assembly also includes a guide rod and a guide sleeve, the guide rod is disposed in the shell and the length extension direction of the guide rod is parallel to the height direction of the shell, the guide sleeve is slidably mounted on the guide rod, and the guide sleeve is fixed to the pressure plate.

[0021] In one embodiment, the number of the guide rods and the number of the guide sleeves are both plural, and the guide rods correspond to the guide sleeves one by one.

[0022] In one of the embodiments, a relief groove is respectively formed on two sides of the pressure plate, and the relief groove is used to avoid the elastic pressing component.

[0023] In one embodiment, the reagent detection device further comprises a driving member disposed on the shell, wherein the driving member is connected to the pressing head and is used to drive the pressing head and the pressing plate to perform lifting and lowering movements along the height direction of the shell.

[0024] In one embodiment, the reagent detection device further comprises a driving assembly disposed in the housing, the driving assembly being connected to the bottom of the tray and used to drive the tray to rotate. The driving assembly may include but is not limited to a motor.

[0039] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0040] See also Figures 1 to 8 In some embodiments, the present invention provides a reagent detection device 10, which includes a housing 100, a tray 200, two synchronous belt assemblies 300, an elastic tensioning assembly 400 and a pressing assembly 500. Figure 1 As shown, the shell 100 is provided with an insertion hole 110 for inserting the reagent disk 800; the tray 200 is rotatably arranged in the shell 100; the two synchronous belt assemblies 300 are arranged in the shell 100 and are respectively located on both sides of the tray 200, and the length extension direction of the synchronous belt assembly 300 is parallel to the axial direction of the insertion hole 110; the elastic tensioning assembly 400 is arranged in the shell 100 and is arranged above the synchronous belt assembly 300 at intervals; the clamping assembly 500 is arranged in the shell 100 and can be lifted and lowered along the height direction of the shell 100 to approach or move away from the tray 200.

[0041] like Figure 4 and Figure 5 As shown, when the reagent tray 800 is inserted into the insertion hole 110, the elastic tensioning assembly 400 elastically abuts against the top of the reagent tray 800 so that the two sides of the bottom of the reagent tray 800 are respectively pressed against the two synchronous belt assemblies 300, and the two synchronous belt assemblies 300 can transfer the reagent tray 800 to the top of the tray 200;

[0042] like Figure 6 and Figure 7 As shown, when the reagent tray 800 is transferred to the top of the tray 200, the clamping assembly 500 can descend along the height direction of the shell 100 and synchronously press down the two synchronous belt assemblies 300, and make the reagent tray 800 carried by the synchronous belt assembly 300 descend together, so that the top of the reagent tray 800 is separated from the elastic tensioning assembly 400, until the clamping assembly 500 fixes the reagent tray 800 on the tray 200, and the bottom of the reagent tray 800 is separated from the two synchronous belt assemblies 300.

[0043] The reagent detection device 10 of the utility model can at least achieve the following beneficial effects: Figure 4 and Figure 5 As shown, when the reagent disk 800 is inserted into the housing 100 from the insertion hole 110, the reagent disk 800 will be clamped between the elastic tensioning assembly 400 and the synchronous belt assembly 300, as shown in FIG. Figure 6 and Figure 7 As shown, the synchronous belt assembly 300 can then transfer the reagent disk 800 to the top of the tray 200, and the pressing assembly 500 descends and presses down the synchronous belt assembly 300, as shown in FIG. Figure 8As shown, the synchronous belt assembly 300 is pressed downward, and the reagent tray 800 on the synchronous belt assembly 300 also drops together. The drop distance exceeds the movement stroke of the elastic tensioning assembly 400, so the top of the reagent tray 800 is separated from the elastic tensioning assembly 400. Figure 7 As shown, when the reagent tray 800 is lowered onto the tray 200, the synchronous belt assembly 300 can be pressed down by the pressing assembly 500, at which time the bottom of the reagent tray 800 is also separated from the synchronous belt assembly 300, and the reagent tray 800 is also pressed and fixed on the tray 200 by the pressing assembly 500, and the tray 200 can drive the reagent tray 800 to rotate for detection. It should be emphasized that during the loading process of the reagent tray 800, it is clamped between the elastic tensioning assembly 400 and the synchronous belt assembly 300, and the movement of the reagent tray 800 can be limited by friction, thereby preventing the reagent tray 800 from being offset in the housing 100 after insertion, ensuring that the reagent tray 800 can be accurately transferred to the top of the tray 200, so the reagent detection device 10 of the present application has higher adaptability, and the reagent tray 800 loading process is very stable, and can be applied to special environments such as vehicle environments.

[0044] Specifically, Figure 3 As shown, in some embodiments, the number of the elastic tensioning components 400 is set to two, and each of the elastic tensioning components 400 is arranged above one of the synchronous belt components 300 at intervals; when the reagent tray 800 is inserted into the insertion hole 110, one side of the reagent tray 800 can be elastically abutted between one of the synchronous belt components 300 and one of the elastic tensioning components 400, and the other side of the reagent tray 800 can be elastically abutted between another synchronous belt component 300 and another elastic tensioning component 400. During the loading process of the reagent tray 800, both sides of the reagent tray 800 are clamped between the elastic tensioning component 400 and the synchronous belt component 300. Such a structural setting can further improve the stability of the reagent tray 800 during loading, and what is clamped is the edge of the reagent tray 800, which will not affect the main structure in the middle of the reagent tray 800, such as avoiding the liquid capsule and valve on the reagent tray 800, thereby ensuring the integrity and effectiveness of the reagent tray 800.

[0045] More specifically, if Figure 5As shown, in some embodiments, the elastic tensioning assembly 400 includes a bracket 410, a rolling member 420 and an elastic member 430, one end of the elastic member 430 is connected to the shell 100, the other end of the elastic member 430 is connected to the side of the bracket 410 facing away from the synchronous belt assembly 300, and the rolling member 420 is rotatably connected to the side of the bracket 410 facing the synchronous belt assembly 300; when the reagent tray 800 is inserted into the insertion hole 110, the rolling member 420 abuts against the top of the reagent tray 800 and can press the reagent tray 800 above the synchronous belt assembly 300 under the elastic force of the elastic member 430, and the rolling member 420 can roll on the top of the reagent tray 800 when the synchronous belt assembly 300 drives the reagent tray 800 to move. When the reagent tray 800 is loaded, the reagent tray 800 is elastically clamped between the elastic tensioning assembly 400 and the synchronous belt assembly 300. Even if the thickness dimensions of different reagent trays 800 are different, the elastic member 430 can be adaptively compressed so that the rolling member 420 is always tightly attached to the top of the reagent tray 800, thereby preventing the elastic tensioning assembly 400 from exerting excessive pressure on the reagent tray 800 and damaging the structure of the reagent tray 800.

[0046] More specifically, if Figure 5 As shown, in some embodiments, the number of the rolling elements 420 is set to be multiple, and the multiple rolling elements 420 are arranged at intervals along the length extension direction of the bracket 410, and the length extension direction of the bracket 410 is parallel to the synchronous belt assembly 300. Among them, the rolling element 420 can be a roller or a ball. Increasing the number of the rolling elements 420 and arranging them along the transmission direction of the synchronous belt assembly 300 can increase the contact points of the rolling elements 420 with the reagent disc 800, and the direction in which the reagent disc 800 is transmitted is consistent, which is conducive to further improving the stability of the reagent disc 800 loading process.

[0047] See also Figure 2 and Figure 5In some embodiments, the pressing assembly 500 includes a pressing head 510 that can move up and down along the height direction of the shell 100 and a pressing plate 520 connected to the pressing head 510, and the pressing plate 520 is provided with four pressing parts 530, two of which are located above one of the synchronous belt assemblies 300 and are arranged at intervals, and the other two of the pressing parts 530 are located above another of the synchronous belt assemblies 300 and are arranged at intervals; when the reagent disk 800 is transferred to the top of the tray 200, the pressing assembly 500 can move up and down along the shell 100. The height direction of the body 100 is lowered, the two pressing parts 530 avoid the reagent tray 800 and abut against the two ends of one of the synchronous belt components 300, and the other two pressing parts 530 avoid the reagent tray 800 and abut against the two ends of the other synchronous belt component 300, so that the two synchronous belt components 300 are partially depressed and the reagent tray 800 is lowered to abut against the tray 200, until the pressure head 510 fixes the reagent tray 800 on the tray 200, and the bottom of the reagent tray 800 is separated from the two synchronous belt components 300.

[0048] Furthermore, if Figure 2 As shown, in one embodiment, the clamping assembly 500 also includes a guide rod 540 and a guide sleeve 550, the guide rod 540 is disposed in the shell 100 and the length extension direction of the guide rod 540 is parallel to the height direction of the shell 100, the guide sleeve 550 is slidably mounted on the guide rod 540, and the guide sleeve 550 is fixed to the pressure plate 520.

[0049] Furthermore, if Figure 2 As shown, in one embodiment, the number of the guide rods 540 and the guide sleeves 550 are both set to be multiple, and the guide rods 540 correspond to the guide sleeves 550 one by one. Figure 2 In the illustrated embodiment, the number of the guide rod 540 and the guide sleeve 550 are both set to two, and the two guide rods 540 are respectively located on opposite sides of the synchronous belt assembly 300. Such a structural setting can limit the movement of the pressing plate 520, prevent the pressing plate 520 from being offset, and make the pressing plate 520 and the pressing part 530 thereon more stable when performing lifting and lowering movements, thereby making the deformation of the synchronous belt assembly 300 squeezed by the pressing part 530 more stable, ensuring that the reagent disk 800 on the synchronous belt assembly 300 can be stably lifted and lowered.

[0050] Furthermore, if Figure 2 As shown, in some embodiments, a avoidance groove 521 is respectively formed on both sides of the pressing plate 520 , and the avoidance groove 521 is used to avoid the elastic pressing component 500 .

[0051] Furthermore, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the reagent detection device 10 also includes a driving member 600 disposed on the shell 100, and the driving member 600 is connected to the pressure head 510 and is used to drive the pressure head 510 and the pressure plate 520 to move up and down along the height direction of the shell 100.

[0052] Furthermore, in some embodiments, the synchronous belt assembly 300 includes a synchronous belt 310 and a motor 320 for driving the synchronous belt 310 .

[0053] Furthermore, in some embodiments, the reagent detection device 10 also includes a first sensor and a second sensor disposed in the shell 100, the first sensor being used to detect whether a reagent disk 800 has been inserted into the insertion hole 110, and when the first sensor detects that the reagent disk 800 has been inserted, the synchronous belt assembly 300 is started and used to transfer the reagent disk 800 to the top of the tray 200, and the second sensor is used to detect whether the reagent disk 800 has been transferred to the top of the tray 200, and when the second sensor detects that the reagent disk 800 has been transferred to the top of the tray 200, the clamping assembly 500 is started and descends along the height direction of the shell 100.

[0054] See also Figure 5 In some embodiments, the reagent detection device 10 further includes a driving assembly 700 disposed in the housing 100 , and the driving assembly 700 is connected to the bottom of the tray 200 and is used to drive the tray 200 to rotate.

[0055] See also Figure 3 and Figure 7 In some embodiments, a limiting post 210 is disposed at the center of the tray 200 , and the limiting post 210 is used to fit the limiting hole 810 at the center of the reagent disk 800 .
