Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to an immune chromatography analyzer. BACKGROUND

[0002] The immune chromatography reagent card is a commonly used detection device in medical detection, and is mainly used for detecting virus antigens, antibodies, parasite antigens, antibodies, specific reaction proteins, specific lipases, progesterone and cortisol based on fluorescence, colloidal gold and other methodologies. The immune chromatography reagent card is detected by being inserted into the immune chromatography analyzer. In order to reduce the occupied space of the immune chromatography analyzer, the existing immune chromatography reagent card is inserted into the internal part of the instrument as much as possible, so that the reagent card is too short to be exposed, and the manual card pulling operation is inconvenient. SUMMARY

[0003] Therefore, the utility model provides an immune chromatography analyzer.

[0004] The immune chromatography analyzer provided by the utility model comprises:

[0005] A shell assembly;

[0006] A reagent card seat connected with the shell assembly, the reagent card seat being provided with an opening and a card slot in communication with the opening, and a reagent card to be detected being inserted into the card slot through the opening for detection;

[0007] A buckle assembly connected with the shell assembly or the reagent card seat, the buckle assembly being used for cooperating with a groove arranged on the reagent card to lock the reagent card when the reagent card is inserted into position;

[0008] An elastic assembly connected with the shell assembly or the reagent card seat, the elastic assembly being compressed when the reagent card is inserted into position, and the elastic assembly being used for pushing the reagent card towards the opening when the buckle assembly is unlocked from the groove on the reagent card.

[0009] As can be seen from the above technical solution, the immune chromatography analyzer provided by the utility model is compressed when the reagent card is inserted into position, and the reagent card is pushed towards the opening when the buckle assembly is unlocked from the groove on the reagent card. Thus, when the reagent card is detected, the reagent card can be exposed from the shell assembly by a larger section under the pushing of the elastic assembly, so as to facilitate the operation personnel to take the card. Moreover, since the reagent card is pushed out by the elastic assembly after being detected, the reagent card can be arranged to be completely inserted into the internal part of the immune chromatography analyzer when the reagent card is inserted into the immune chromatography analyzer for analysis, so as to reduce the occupied space of the immune chromatography analyzer.

[0020] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

Moreover, because the reagent card 200 is pushed out by elastic component 40 after detection, therefore when the reagent card 200 is inserted in the immune chromatography analyzer 100 and is analyzed, can be set to be inserted in the inside of immune chromatography analyzer 100 completely, thereby reducing the occupation space of immune chromatography analyzer 100.

[0023] As Figure 5 And Figure 6 As shown, in some embodiments, buckle assembly 30 includes buckle piece 31 and first elastic piece 32, buckle piece 31 is rotatably connected with reagent card seat 20, and buckle piece 31 is used for cooperating with the groove 201 on the reagent card 200 to lock the reagent card 200. First elastic piece 32 is arranged on reagent card seat 20, and first elastic piece 32 is used to provide the elastic force applied to buckle piece 31, so that buckle piece 31 and the reagent card 200 inserted into card slot 20b remain clamped. First elastic piece 32 can be but not limited to spring.

[0024] It should be noted that due to the elastic force of first elastic piece 32, when the reagent card 200 is inserted in position, the part of buckle piece 31 cooperating with card slot 20b is embedded in card slot 20b, which will make a click sound, and the operator can determine whether the reagent card 200 is inserted in position.

[0025] It should also be noted that the fastener 31 is not limited to being rotatably connected to the reagent holder 20. For example, in some other embodiments, the fastener 31 can also be slidably connected to the reagent holder 20. For example, the fastener 31 is attached to the reagent holder 20. Figure 5 The upper and lower parts are slidably connected to the reagent card holder 20. The first elastic element 32 is disposed at the bottom of the buckle 31. The first elastic element 32 is used to provide elastic force applied to the buckle 31 so that the buckle 31 is engaged with the reagent card 200 inserted into the card slot 20b.

[0026] It should also be noted that the latching assembly 30 is not limited to the latching member 31 and the first elastic member 32 described above. For example, in some other embodiments, the latching assembly 30 may be a spring plunger.

[0027] like Figure 6 and Figure 7 As shown, in some embodiments, the card slot 20b is disposed at the bottom of the reagent card 200. The reagent card holder 20 includes a base plate 21, which has a notch 211. When the reagent card 200 is inserted into place, the groove 201 on the reagent card 200 is positioned opposite to the notch 211. The fastening member 31 is disposed at the bottom of the reagent card holder 20. The fastening member 31 includes a main body 311 and a fastening part 312. The main body 311 includes a first end A1 and a second end A2. The first end A1 of the main body 311 is rotatably connected to the reagent card holder 20. The elastic force of the first elastic member 32 is applied to the main body 311. The fastening part 312 is disposed at the second end A2 of the main body 311, and part of the fastening part 312 extends into the inside of the card slot 20b through the notch 211. When the reagent card 200 is inserted into the card slot 20b, the front end of the reagent card 200 abuts against the latching part 312 and pushes the latching part 312 toward the notch 211 until the reagent card 200 is inserted into place. The groove 201 on the reagent card 200 is positioned opposite to the notch 211, and the latching part 312 is embedded into the card slot 20b of the reagent card 200 under the elastic force of the first elastic member 32 to lock the reagent card 200.

[0028] Of course, the card slot 20b is not limited to being located at the bottom of the reagent card 200, but can also be located at the top of the reagent card 200 or on both sides of the reagent card 200. Correspondingly, the notch 211 is not limited to being located at the bottom plate 21 of the reagent card holder 20, but can also be located at the top plate of the reagent card holder 20 or on both sides of the reagent card holder 20. Correspondingly, the fastener 31 is not limited to being located at the bottom of the reagent card holder 20, but can also be located at the top of the reagent card holder 20 or on both sides of the reagent card holder 20. The specific location can be determined according to the actual design requirements.

[0029] like Figure 7As shown, in some embodiments, the buckle part 312 is provided with a slope 3121, which is abutted by the reagent card 200 when the reagent card 200 is inserted into the card slot 20b, so as to drive the buckle part 31 to rotate or slide away from the reagent card 200 until the buckle part 312 is opposite to the groove 201 on the reagent card 200, and then the buckle part 312 is embedded into the card slot 20b under the action of the first elastic member 32.

[0030] As shown, Figure 8 In some embodiments, the immunochromatographic analyzer 100 further comprises an unlocking assembly 50, which is configured to apply a force to the buckle part 31 so as to drive the buckle part 31 to rotate or slide away from the reagent card 200.

[0031] As shown, Figure 8 In some embodiments, the immunochromatographic analyzer 100 further comprises an optical assembly 60, which is configured to be movable at least along the card slot 20b so as to scan the reagent card 200 inserted into the card slot 20b. The unlocking assembly 50 is mounted to the optical assembly 60, and the unlocking assembly 50 moves with the optical assembly 60, as shown in Figure 8 and Figure 9 As shown, the optical assembly 60 moves along the E direction when scanning the reagent card 200, and the unlocking assembly 50 moves along the E direction with the optical assembly 60. After the optical assembly 60 completes the scanning, the unlocking assembly 50 abuts to and presses the buckle part 31, so as to drive the buckle part 31 to rotate or slide away from the reagent card 200.

[0032] In this embodiment, by mounting the unlocking assembly 50 to the optical assembly 60, the unlocking assembly 50 and the optical assembly 60 can share a set of driving mechanisms, which reduces the number of driving mechanisms, simplifies the structure, and reduces the cost. Moreover, the unlocking of the unlocking assembly 50 to the buckle part 31 and the scanning of the optical assembly 60 are a linkage process, that is, the unlocking assembly 50 automatically unlocks the buckle part 31 after the optical assembly 60 completes the scanning, without the need for an operator to apply an unlocking instruction, which is convenient and efficient.

[0033] Of course, in other embodiments, the unlocking assembly 50 is not mounted to the optical assembly 60, and the unlocking assembly 50 can be additionally provided with a set of driving mechanisms for driving. It should be further noted that, in this embodiment, the unlocking assembly 50 is automatically driven to unlock the buckle part 31, and in other embodiments, the unlocking assembly 50 can be manually operated by an operator to unlock, which can be determined according to actual design needs.

[0034] As shown, Figure 8As shown, in some embodiments, the unlocking component 50 includes a cantilever 51 and an abutment 52. The cantilever 51 is connected to the optical component 60, and the abutment 52 is connected to the cantilever 51. When the abutment 52 abuts against the latch 31, it presses the latch 31 so that the latch 31 rotates or slides away from the reagent card 200.

[0035] like Figure 9 As shown, in some embodiments, the latching member 31 includes a mating portion 313, which at least partially protrudes from the upper surface of the reagent card holder 20. An abutting portion 52 extends obliquely downward from the cantilever 51 toward the reagent card holder 20. When the abutting portion 52 abuts against the mating portion 313, it presses the mating portion 313, causing the latching member 31 to rotate or slide away from the reagent card 200. Here, the "upper surface of the reagent card holder 20" refers to the orientation of the immunochromatographic analyzer 100 in its normal operating state.

[0036] When the abutting part 52 abuts against the mating part 313 of the latching member 31, since the abutting part 52 extends downward towards the reagent card holder 20, the abutting part 52 will form a downward component force on the latching member 31. This component force will press the mating part 313 downward, causing the latching member 31 to rotate or slide away from the reagent card 200, so as to unlock the latching member 31 and the reagent card 200.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments, the elastic component 40 includes a push rod 41, a push block 42, and a second elastic member 43. The push rod 41 is slidably connected to the reagent card holder 20. The push block 42 is connected to the end of the push rod 41 facing the card slot 20b. The second elastic member 43 is mounted on the push rod 41 and abuts against the reagent card holder 20. The second elastic member 43 provides a spring force applied to the push rod 41 so that the push rod 41 drives the push block 42 to push the reagent card 200 toward the opening 20a. The second elastic member 43 can be, but is not limited to, a spring.

[0038] In some embodiments, the torque generated by the elastic component 40 acting on the latching member 31 is less than the torque generated by the first elastic component 32 acting on the latching member 31. With this embodiment, the reagent card 200 can be securely locked, preventing the reagent card 200 from being suddenly ejected during the testing process.

[0039] like Figure 3As shown in the drawings, in some embodiments, the reagent card seat 20 comprises a card slot portion 22 and a first frame portion 23, the card slot portion 22 is provided with the card slot 20b, the card slot portion 22 comprises an open end 22a and a bottom end 22b, the open end 22a is provided with the opening 20a. The first frame portion 23 is arranged at the bottom end 22b of the card slot portion 22, the first frame portion 23 is enclosed to form a first through hole 231, the fitting portion 313 of the buckle member 31 is arranged through the first through hole 231 and partially exposed on the upper surface of the reagent card seat 20.

[0040] As shown in the drawings, Figure 3 In some embodiments, the reagent card seat 20 further comprises a second frame portion 24, the second frame portion 24 is arranged at the bottom end 22b of the card slot portion 22, the first frame portion 23 and the second frame portion 24 are arranged side by side in the width direction of the card slot portion 22, the second frame portion 24 comprises a first side wall 241 and a second side wall 242 in the extension direction of the card slot 20b, the first side wall 241 is closer to the card slot portion 22 relative to the second side wall 242, the top rod 41 is movably arranged through the first side wall 241 and the second side wall 242, the top rod 41 is provided with a stop portion 411, and the second elastic member 43 is sleeved on the top rod 41 and located between the second side wall 242 and the stop portion 411.

[0041] As shown in the drawings, Figure 3 and Figure 4 In some embodiments, the first frame portion 23 is connected with the bottom end 22b of the card slot portion 22, the second frame portion 24 is connected with the first frame portion 23 and is arranged in a spaced manner with the bottom end 22b of the card slot portion 22, and the push block 42 is arranged between the second frame portion 24 and the card slot portion 22.

[0042] As shown in the drawings, Figure 4 In some embodiments, the immunochromatographic analyzer 100 further comprises a sensor 70, when the reagent card 200 is inserted into position, the push block 42 triggers the sensor 70 to generate a signal that the reagent card 200 is inserted into position. The sensor 70 can be but is not limited to a micro switch. In this embodiment, by arranging the sensor 70 to detect whether the reagent card 200 is inserted into position, feedback can be provided to the operator, so as to avoid the situation that the reagent card 200 is not inserted into position and affect the detection result.

[0043] As shown in the drawings, Figure 4 In some embodiments, the sensor 70 is arranged on the side of the second frame portion 24 opposite to the first frame portion 23.

[0044] In some embodiments, after the elastic assembly 40 pushes the reagent card 200 into position, the second elastic member 43 is in a compressed state, at this time, the elastic force of the second elastic member 43 is configured to be consistent with the friction force between the reagent card 200 and the reagent card seat 20.

[0045] As shown in the drawings, Figure 2As shown, in order to improve the detection efficiency, the immunochromatography analyzer 100 is provided with a plurality of parallel reagent card seats 20, and a plurality of reagent cards 200 can be detected. Due to the operation of the plurality of card slots 20b, it is likely that the adjacent card slot 20b is being inserted when the card slot 20b automatically ejects the card. If the elastic component 40 pushes the reagent card 200 out during the process, the second elastic member 43 is provided with a larger elastic force, the reagent card 200 exits faster, and the operator being inserted may be injured. In the embodiment, after the elastic component 40 pushes the reagent card 200 to the position, the elastic force of the second elastic member 43 is configured to be consistent with the friction force between the reagent card 200 and the reagent card seat 20. In this way, the reagent card 200 will not be too fast during the pushing process, and the operator can be prevented from being injured.
