Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to reagent strip carriers and testing equipment. Background Technology

[0002] A test strip is a device that immobilizes a specific chemical reagent or biomolecule (such as an antibody or enzyme) on a strip-shaped carrier material (such as a nitrocellulose membrane, plastic, or paper) for the rapid detection of a target analyte in a sample. It is widely used in various medical tests.

[0003] A test strip carrier is a device used to load and hold test strips for testing on automated equipment.

[0004] Patent document CN213677705U discloses a usable reagent strip tray. This structure includes a lever fixing mechanism for locking and unlocking the lever. Specifically, locking is achieved by the locking element pressing against the top of the swing arm connected to the lever. Unlocking is achieved by pulling the locking element to the inside of the swing arm, thereby releasing the restriction on the swing arm's rotation.

[0005] However, in this structure, while one hand operates the pulling component, the other hand rotates the swing arm to move it above the restricted section to finally unlock the lever. This structure is obviously inconvenient to operate. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems in the prior art and to provide a reagent strip carrier and a testing device.

[0007] The objective of this utility model is achieved through the following technical solution: A reagent strip carrier includes a main body, on which a reagent strip clamping mechanism and a locking mechanism are provided. The reagent strip clamping mechanism includes at least one rotating arm, and the locking mechanism is used to lock the rotating arm in the clamping position. The main body is also provided with a lifting component that abuts against the bottom of the rotating arm in the clamping position. When the locking mechanism releases the locking of the rotating arm, the lifting component drives the rotating arm to rotate upward to a position where the locking mechanism can no longer lock the rotating arm.

[0008] Preferably, the outer walls of the side plates on the two long sides of the main body are respectively provided with recesses that are positioned opposite each other.

[0009] Preferably, a locking hole is provided at the rotating arm, and the locking mechanism includes a locking member that can move along the width direction of the main body. The locking member is connected to an elastic member that extends its locking portion to the outside of the main body. The locking portion extends into the locking hole of the rotating arm in the pressed position to lock the rotating arm. When the locking portion exits from the locking hole, the locking of the rotating arm is released.

[0010] Preferably, the locking part is provided with a retractable force-bearing surface. During the rotation of the rotating arm toward the pressing position, the rotating arm drives the locking member to move toward the inside of the main body through the retractable force-bearing surface until the locking part is located inside the rotating arm.

[0011] Preferably, the locking member is connected to an unlocking member that drives it to exit the locking hole. The unlocking member is located in a mounting groove at the bottom of the body and has an operating part extending beyond a first end of the body. The unlocking member is movably disposed on a guide shaft on the body along the width direction of the body. The elastic member is a spring fitted on the locking member. One end of the spring abuts against the abutment plate of the locking member, and the other end abuts against the groove wall of the groove at the bottom of the body away from the abutment plate.

[0012] Preferably, the unlocking element is movably connected to the guide shaft via a linear bearing.

[0013] Preferably, there are two rotating arms distributed on both sides of the main body, and the locking mechanism includes locking members corresponding to the two rotating arms respectively, with each locking member connected to an unlocking member.

[0014] Preferably, the two rotating arms are L-shaped, and a probe protective cover limiting rod is provided between them. The probe protective cover limiting rod is provided with a locking slot that is directly opposite to each reagent strip slot on the main body.

[0015] Preferably, the lifting assembly is a spring plunger.

[0016] The testing equipment includes a reagent strip carrier as described in any of the above descriptions.

[0017] The advantages of this utility model's technical solution are mainly reflected in: This invention provides a lifting assembly at the bottom of the swing arm. When the locking mechanism releases the lock on the swing arm, the lifting assembly can lift and rotate the rotating arm to a position where the locking mechanism cannot lock it. This eliminates the need to operate the locking mechanism manually when operating the rotating arm or the lever, greatly facilitating the operator's work.

[0018] This invention features recesses formed on both outer walls of the main body to facilitate manual handling of the reagent strip carrier tray. Additionally, the external structure can be secured to the recesses via latches, thus facilitating the fixation of the reagent strip carrier tray in conjunction with the external structure.

[0019] The locking mechanism of this invention is located entirely at the bottom and side of the main body. Compared with the prior art, the new structure makes the entire reagent strip carrier tray more concise and clear. At the same time, this structure allows for a greater distance between the locking element and the axis around which the rotating arm rotates, thereby providing a more reliable lock on the rotating arm.

[0020] This invention sets the probe protective cover limiting rod on the rotating arm. When the rotating arm is opened, the probe protective cover limiting rod can rotate and open accordingly, thereby releasing the restriction on the opened probe protective cover and making it easier to remove the reagent strip from the reagent strip carrier tray, further facilitating the operation.

Detailed Implementation

[0022] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

[0023] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Example 1 The reagent strip carrier disclosed in this utility model will be described below with reference to the accompanying drawings, as shown in the attached drawings. Figure 1As shown, it includes a main body 100, on which a reagent strip clamping mechanism 200 and a locking mechanism 300 are provided. The reagent strip clamping mechanism 200 includes at least one rotating arm 210. The locking mechanism 300 is used to lock the rotating arm 210 in the clamping position. The main body 100 is also provided with a lifting component 400 that abuts against the bottom of the rotating arm 210 in the clamping position. When the locking mechanism 300 releases the locking of the rotating arm 210, the lifting component 400 drives the rotating arm 210 to rotate upward to a position where the locking mechanism 300 can no longer lock the rotating arm 210.

[0025] As attached Figure 1 Appendix Figure 2 As shown, the main body 100 is generally a flat cuboid, but its specific shape can be designed into other shapes as needed, and is not limited here. A row of reagent strip slots 110 are formed on the main body 100, distributed along the width direction W of the main body 100. The number of reagent strip slots can be designed as needed, for example, 6, or other numbers, and is not limited here. Each reagent strip slot 110 extends along the length direction L of the main body 100 and is used to hold a reagent strip A. The specific shape of the reagent strip slot 110 is adaptively designed according to the shape of the reagent strip A to be held, and is not limited here.

[0026] As attached Figure 1 As shown, recesses 120 are respectively provided on the outer walls of the side plates on the two long sides of the main body 100. The recesses 120 are roughly square and extend downward from the top of the side plate to near the bottom of the side plate. The operator can use his thumb to hold the recess 120 on one side and use another finger to hold the recess 120 on the other side, so as to make it easier to grasp the main body 100.

[0027] As attached Figure 1As shown, the reagent strip clamping mechanism 200 includes a pressure rod 220, which extends along the width direction W of the main body 100 and has a length approximately equal to the width of the main body. At least one end of the pressure rod 220 is vertically connected to a rotating arm 210. Preferably, both ends of the pressure rod 220 are connected to a rotating arm 210, and the two rotating arms 210 are distributed on both sides of the main body. One end of each rotating arm 210 is connected to one end of the pressure rod 220, and the other end of each rotating arm 210 is pivotally connected to the side of the main body 100. The pivot axis (not shown in the figure) connecting the rotating arm 210 and the main body is located at the first end 130 of the main body 100 and extends along the width direction of the main body. Thus, the rotating arm 210 can rotate relative to the main body 100, thereby driving the pressure rod 220 to rotate around the pivot axis to open and close. Meanwhile, the main body 100 may be provided with a clearance opening for the pressure rod 220 to press on the reagent strip A. Of course, this is not necessary. For example, if the position where the reagent strip A is pressed by the pressure rod 220 is higher than the top of the main body 100, then the clearance opening is not required.

[0028] As attached Figure 2 As shown, when the pressure rod 220 presses on the reagent strip A, the pressure rod 220 and the rotating arm 210 are in the pressed position. At this time, the rotating arm 210 needs to be limited by the locking mechanism 300 so that the pressure rod 220 connected to the rotating arm 210 can remain pressed on the reagent strip A.

[0029] As attached Figure 1 - Appendix Figure 3 As shown, a locking hole 211 is provided at the rotating arm 210. The shape of the locking hole 211 can be designed as needed; in this embodiment, it is a rectangular hole. Correspondingly, the locking mechanism 300 includes a locking member 310 that can move along the width direction W of the main body 100. The locking member 310 is connected to an elastic member 320 that partially protrudes outside the side of the main body 100. The portion of the locking member 310 extending outside the main body 100 inserts into the locking hole 211 of the rotating arm 210 in the pressed position, and the bottom surface of the locking portion presses against the bottom surface of the locking hole, thereby locking the rotating arm 210. When the locking member 310 exits from the locking hole 211, the locking of the rotating arm 210 is released.

[0030] Specifically, the locking member 310 is movably disposed in the guide hole 160 on the side plate of the main body 100. The shape of the guide hole 160 can be designed as needed, for example, it can be square. Correspondingly, the locking member 310 includes a telescopic rod segment 311 that is adapted to the shape of the guide hole and passes through the guide hole, and a connecting rod segment 312 that is coaxial with the telescopic rod segment 311 and located at the inner end of the telescopic rod segment 311.

[0031] The elastic element 320 causes a portion of the outer end of the telescopic rod segment 311 to extend beyond the side of the main body 100. This extended portion is the locking portion 313, which has a retractable force-bearing surface 314. This retractable force-bearing surface 314 is, for example, an inclined or arc-shaped surface that slopes downwards and outwards from the top of the locking portion. During the rotation of the rotating arm 210 towards the pressing position, the rotating arm 210 drives the locking element 310 to move inwards towards the inside of the main body 100 via the retractable force-bearing surface 314. Specifically, the bottom of the rotating arm 210 presses against the retractable force-bearing surface 314. As the rotating arm 210 rotates downwards, the pressure it applies to the retractable force-bearing surface 314 drives the locking element 310 to move inwards towards the main body 100, and the telescopic rod segment 311 moves to the inside of the rotating arm 210. During this process, the elastic element 320 is compressed and deformed. As the rotating arm 210 continues to rotate downwards until the locking hole 211 aligns with the telescopic rod segment 311, the locking member 310, no longer restricted by the inner side of the rotating arm 210, translates towards the rotating arm 210 and partially inserts into the locking hole 211 under the reaction force of the elastic member 320, thus achieving locking. Therefore, when the rotating arm 210 rotates towards the reagent strip A, the locking mechanism 300 can automatically lock the rotating arm 210.

[0032] A spring, namely the elastic element 320, is fitted around the outer periphery of the connecting rod segment 312. One end of the spring abuts against the abutment plate 315 of the locking element 310. The abutment plate 315 connects the telescopic rod segment 311 and the connecting rod segment 312. The other end of the spring abuts against the groove wall of a groove 140 at the bottom of the main body 100, away from the abutment plate 315. The groove 140 is convex in shape. One end of the connecting rod segment 312 extending outside the small groove of the groove 140 is connected to an unlocking element 330 for driving it out of the locking hole 211 to unlock the rotating arm 210. The unlocking element 330 is screwed to the connecting rod segment 312.

[0033] The unlocking member 330 is located in the mounting groove 150 at the bottom of the main body 100 and has an operating part 331 extending beyond the first end 130 of the main body 100. The unlocking member 330 is movably disposed on a guide shaft 340 on the main body 100 along the width direction W. Preferably, there are two guide shafts 340. To facilitate the installation and positioning of the guide shaft, the main body is provided with a through hole along its width direction. Simultaneously, the main body is provided with two screw holes perpendicular to and communicating with the through hole, located near both ends of the through hole. The guide shaft is disposed in the through hole, and both ends of the guide shaft are positioned by bolts threaded to the two screw holes. Furthermore, to make the movement of the unlocking member 330 smoother for easier unlocking, the unlocking member 330 is movably connected to the guide shaft 340 via a linear bearing 350.

[0034] Furthermore, since there are two rotating arms 210 distributed on both sides of the main body 100, the locking mechanism 300 includes locking members 310 corresponding to the two rotating arms 210 respectively, and the two locking members 310 are respectively connected to an unlocking member 330. This structure can improve the stability of the locking mechanism 300 and facilitate the unlocking operation.

[0035] As attached Figure 1 As shown, the lifting assembly 400 is a spring plunger, the specific structure of which is known technology. It typically includes a housing 410, a telescopic column 420, and a spring (not shown in the figure). The housing may have external threads and be disposed in a mounting hole on the main body. The telescopic column is axially movable within the housing and will not detach from it. A spring is disposed between the telescopic column and the housing, causing a portion of the telescopic column to extend beyond the top of the housing. When the rotating arm 210 rotates to the pressing position, the downward pressure of the rotating arm 210 causes the telescopic column to retract into the housing. At this time, the spring inside the housing is compressed and applies an upward lifting force to the telescopic column. When the rotating arm 210 is unlocked, the telescopic column is lifted upward under the reaction force of the spring, thereby lifting the rotating arm 210 that it is abutting.

[0036] When unlocking is required, the two operating parts 331 are pinched with fingers, causing the two unlocking parts 330 to move towards each other. At this time, the unlocking parts 330 drive the two locking parts 310 to move towards each other, causing the locking parts 310 to disengage from the locking holes 211. Since the locking parts 310 no longer exert pressure on the rotating arm 210, the upward lifting force of the lifting assembly 400 lifts the rotating arm 210 upwards and rotates it by a certain angle, making the bottom surface of the locking hole 211 higher than the bottom surface of the telescopic rod section 311. Therefore, when the operator releases the two operating parts 331, although the locking parts 310 will reset under the force of the elastic element, they cannot be inserted into the locking holes 211. (See attached diagram) Figure 1 As shown, the lever 220 can be opened by rotating the rotating arm 210 or the lever 220 with one hand.

[0037] As attached Figure 2 As shown, the two rotating arms 210 are L-shaped, and the pivot shaft (not shown) is connected to the arc-shaped corner of the rotating arm 210. A probe protective cover limiting rod 500 is provided between the short branches 212 of the two rotating arms 210. The two ends of the probe protective cover limiting rod 500 are connected to the two short branches 212 by bolts. Furthermore, a locking slot 510 is provided on the probe protective cover limiting rod 500, which is directly opposite to each reagent strip slot 110 on the main body 100. When the pressure rod 220 is pressed against the reagent strip A, the open probe protective cover A1 on the reagent strip A can move through the locking slot 510 to below the limiting rod, so that the open probe protective cover A1 is blocked by the probe protective cover limiting rod 500 and cannot be closed. At the same time, the length of the long branch 213 of the rotating arm 210 is less than half the length of the main body. This not only simplifies the structure but also better ensures the locking of the rotating arm.
