Description

Technical Field

[0001] The present invention relates to an analyzer, specifically to a handheld analyzer, belonging to the technical field of medical detection. Background Art

[0002] Traditional analyzers are relatively large in size and are usually designed for desktop applications, which are not convenient to carry and operate outdoors. While handheld analyzers have higher flexibility and are suitable for applications in more scenarios. Handheld analyzers can be used in immunoassays with multiple markers. For example, a handheld fluorescence immunoassay analyzer irradiates and scans a test strip to read the fluorescence signal emitted by the fluorescence marker enriched on the detection line of the test strip, so as to achieve quantitative analysis of the analyte.

[0003] When the existing handheld analyzer irradiates and scans a test strip, the test strip needs to be first inserted into the analyzer. After the analyzer finishes reading, the test strip is manually pulled out by the operator and collected and discarded centrally. In order to ensure the stable position of the test strip in the analyzer, there is usually a large frictional resistance between the test strip and the analyzer. Therefore, the operator needs to apply a greater force during the process of pulling out the test strip, greatly increasing the risk of the operator coming into contact with the body fluid sample or blood sample of the subject. Summary of the Invention

[0004] Based on the above background, the purpose of the present invention is to provide a handheld analyzer with convenient operation, which can enable the operator to conveniently take out the used test strip from the analyzer, thus solving the problems described in the background art.

[0005] Another purpose of the present invention is to provide a handheld analysis device having the above handheld analyzer.

[0006] Still another purpose of the present invention is to provide an analysis method using the above handheld analyzer.

[0007] In order to achieve the above invention purposes, the present invention provides the following technical solutions:

[0008] A handheld analyzer includes an analyzer body and a test strip ejection mechanism provided on the analyzer body. The analyzer body is provided with a test strip insertion port and a receiving cavity for accommodating the test strip. The test strip insertion port communicates the receiving cavity with the outside of the analyzer body. The test strip ejection mechanism includes:

[0009] A cover body, the inner wall of the cover body is configured as at least part of the cavity wall of the receiving cavity. The cover body can move relative to the analyzer body between a first position adjacent to the test strip insertion port and a second position away from the test strip insertion port. One end of the cover body away from the test strip insertion port is provided with a baffle, and the baffle is located in the receiving cavity;

[0010] At least two cooperating and oppositely arranged retaining members, at least two of the retaining members being able to switch between a separated state and an abutting state under the action of an external force, wherein at least one retaining member is provided on the cover body, and at least another retaining member is provided on the analyzer body. When the cover body is in the first position, at least two retaining members are in the separated state, and when the cover body is in the second position, at least two retaining members are in the abutting state; and,

[0011] An actuator, a part of the actuator extending outside the analyzer body, the actuator being able to move relative to the analyzer body between an initial position and an actuator position for switching at least two retaining members from the abutting state to the separated state.

[0012] The operator inserts the test strip into the analyzer body through the test strip socket for detection. During the insertion process, the thrust of the test strip is transmitted to the baffle to move the cover body from the first position to the second position. When the cover body is in the second position, it is locked to the second position under the action of the retaining member. At this time, the test strip is located at the detection position, and the analyzer body detects the test strip. After the detection is completed, the operator operates the actuator to switch the retaining member to the separated state, and the cover body moves from the second position to the first position. The baffle pushes the test strip, so that the test strip exits the analyzer body by a certain distance, and the operator only needs to apply a small external force to take out the test strip from the analyzer body.

[0013] Preferably, the test strip ejection mechanism further includes an elastic member, one end of the elastic member abutting against the surface of the baffle away from the test strip socket, the actuator abutting against the end of the elastic member away from the baffle, and the elastic member providing a restoring force for the actuator to return to the initial position.

[0014] Preferably, the cover body is provided with a first limiting member, at least a part of the first limiting member protruding at least partially from the surface of the cover body adjacent to the accommodating cavity and extending towards the accommodating cavity, and restricting the relative position between the test strip and the cover body when the test strip is located in the accommodating cavity. Through the above technical solution, when the operator holds the handheld analyzer inserted with the test strip and changes the holding direction, the test strip is not easily detached from the analyzer body.

[0015] Preferably, the first limiting member includes a spring piece and a limiting block, at least one end of the spring piece being fixedly connected to the cover body, the limiting block being connected to the spring piece, at least a part of the spring piece being able to move relative to the cover body, and the limiting block extending towards the accommodating cavity. Through the above technical solution, the limiting block can more easily disengage from the test strip under the action of an external force, facilitating the operator to take out the test strip from the test strip socket.

[0016] Preferably, the analyzer body is provided with a accommodating member, the accommodating member is provided with a groove, the top of the groove is open, one side of the groove is an open end, the side of the groove opposite to the open end is a closed end, the open end of the groove is adjacent to the test strip insertion port, the cover body and the actuator are sequentially located on the accommodating member along the direction from the test strip insertion port to the closed end of the groove, the cover body covers the top opening of the groove, and the space enclosed by the cover body and the accommodating member is configured as the accommodating cavity.

[0017] Preferably, the cover is slidably connected to the container, the cover is provided with one of a guide block and a guide groove, the container is provided with the other of the guide block and the guide groove, at least a portion of the guide block is provided in the guide groove and can slide along the guide groove; when the cover is in the first position, one end of the guide block abuts against the groove wall of the guide groove adjacent to the test strip insertion port, and when the cover is in the second position, the other end of the guide block abuts against the groove wall of the guide groove away from the test strip insertion port. Through the cooperation of the guide block and the guide groove, the relative sliding of the cover and the container is smooth, and the sliding direction and limit position of the cover relative to the container are limited.

[0018] Preferably, the accommodating member is provided with at least one second stopper protruding from its surface, which abuts against the guide block to prevent the cover from moving from the second position to the first position when the cover is in the first position, and abuts against the guide block to prevent the cover from moving from the first position to the second position when the cover is in the second position.

[0019] Preferably, the bottom of the guide groove has an inclined surface, and the inclined direction of the inclined surface forms an acute angle with the direction in which the accommodating member extends from the test strip insertion port to the baffle. Through the above technical solution, when the cover moves from the first position to the second position, the guide block moves along the inclined surface of the bottom of the guide groove, driving the cover to gradually approach the accommodating member, so that the distance between the cover and the accommodating member gradually decreases, and the inner wall of the top of the cover presses the test strip toward the bottom of the accommodating member groove, thereby further limiting the relative position between the test strip and the cover, and the test strip is less likely to fall out of the analyzer body.

[0020] Preferably, the retaining member includes a blocking portion and a transition portion connected to the blocking portion, the thickness of the end of the transition portion connected to the blocking portion is greater than the thickness of the end of the transition portion away from the blocking portion, and a continuously extending inclined surface is provided between the two ends of the transition portion; when at least two retaining members are in an abutting state, the blocking portions of at least two retaining members abut against each other; when at least two retaining members switch from the abutting state to the separated state, the blocking portion of one retaining member slides along the inclined surface of the transition portion of the other retaining member from the connecting end of the transition portion and the blocking portion to the separated end of the transition portion and the blocking portion. Through the above technical solution, the smoothness of the switching movement of the retaining member between the abutting state and the separated state is improved.

[0021] Preferably, the elastic member is a compression spring. One end of the compression spring abuts against the baffle, and the other end abuts against the actuator. Both the baffle and the actuator are provided with spring fixing pins for sleeving the end portions of the compression spring.

[0022] Preferably, the actuator abuts against the baffle. The actuator includes a button and a slider connected to the button. The button is disposed outside the analyzer body, and the button is slidably connected to the analyzer body. The button can slide relative to the analyzer body in the direction of the test strip insertion port. A part of the slider can switch at least two holding members from the abutting state to the separated state, so that the operator can conveniently operate the slider through the button.

[0023] Preferably, the slider includes a slider body and a protrusion provided on the surface of the slider body. The protrusion extends towards the holding member, and the maximum thickness of the protrusion is greater than the minimum distance between the inner portion of the holding member and its opposite cover surface or its opposite analyzer body surface.

[0024] Preferably, a limiting hole is provided on the surface of the analyzer body, and a part of the button is inserted into the limiting hole. The limiting hole is used to limit the sliding displacement of the button relative to the analyzer body.

[0025] Preferably, the analyzer body is provided with a trigger unit for generating a trigger signal. The trigger unit has a trigger switch, and the cover is provided with a trigger bump. When the cover is in the second position, the trigger bump abuts against the trigger switch. The trigger unit cooperates with other electronic control units in the analyzer body. When the trigger bump abuts against the trigger switch, the trigger unit generates a trigger signal and is read by other electronic control units, so that the handheld analyzer can immediately know that the test strip is inserted and in place at a preset position in the analyzer body.

Detailed implementation manners

[0049] The technical solutions of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the implementation of the present invention is not limited to the following embodiments, and any formal adaptation and / or change made to the present invention will fall within the protection scope of the present invention.

[0050] In the present invention, unless otherwise specified, all parts and percentages are in weight units, and the equipment and raw materials used can be obtained from the market or are commonly used in the art. The methods in the following embodiments are all conventional methods in the art unless otherwise specified. The components or equipment in the following embodiments are all general standard components or components known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods.

[0051] An embodiment of the present invention discloses a handheld analyzer, which includes an analyzer body 1 and a test strip ejection mechanism 2 provided on the analyzer body 1. The analyzer body 1 is provided with a test strip socket 101 and a receiving cavity 102 for accommodating a test strip 3. The test strip socket 101 communicates the receiving cavity 102 with the outside of the analyzer body 1. The test strip ejection mechanism 2 includes a cover body 210, at least two cooperating and oppositely arranged holding members 220, and an actuator 240. The inner wall of the cover body 210 is configured as at least a part of the cavity wall of the receiving cavity 102. The cover body 210 can move relative to the analyzer body 1 between a first position adjacent to the test strip socket 101 and a second position away from the test strip socket 101. One end of the cover body 210 facing away from the test strip socket 101 is provided with a baffle 211, and the baffle 211 is located in the receiving cavity 102. At least two holding members 220 can be switched between a separated state and an abutting state under an external force. Among them, at least one holding member 220 is provided on the cover body 210, and at least another holding member 220 is provided on the analyzer body 1. When the cover body 210 is in the first position, at least two holding members 220 are in the separated state. When the cover body 210 is in the second position, at least two holding members 220 are in the abutting state. A part of the actuator 240 extends outside the analyzer body 1. The actuator 240 can move relative to the analyzer body 1 between an initial position and an execution position that switches at least two holding members 220 from the abutting state to the separated state. Through the cooperation of the components of the test strip ejection mechanism 2, when the cover body 210 is in the first position, at least two holding members 220 are in the separated state; when the cover body 210 is in the second position, at least two holding members 220 are in the abutting state so that the cover body 210 is held in the second position; when the actuator 240 moves from the initial position to the execution position, at least two holding members 220 are switched from the abutting state to the separated state. In this way, the operator can conveniently take out the used test strip 3 from the analyzer with a relatively small external force, reducing the risk of the operator contacting the body fluid sample or blood sample of the subject. Moreover, the structure of the test strip ejection mechanism 2 is reasonable, improving the durability of each component and ensuring the normal operation of the ejection function after long-term use.

[0052] The following will make a detailed description of the embodiments of the present invention with reference to the accompanying drawings. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0053] As Figure 1 and Figure 2 shown, a handheld analyzer includes an analyzer body 1 and a test strip ejection mechanism 2 provided on the analyzer body 1.

[0054] The analyzer body 1 is provided with a test strip socket 101 and a receiving cavity 102 for receiving the test strip 3. The test strip socket 101 communicates the receiving cavity 102 with the outside of the analyzer body 1.

[0055] Specifically, the analyzer body 1 includes an upper housing 110, a lower housing 120, a detection substrate 130, a signal reading module 140, and a signal analysis module 150. The upper housing 110 and the lower housing 120 are buckled with each other, and the internal space surrounded by the upper housing 110 and the lower housing 120 forms the inner cavity of the analyzer body 1. The test strip socket 101 is located at one end of the inner cavity. The detection substrate 130 is detachably fixedly connected to the inner wall of the lower housing 120 and is located inside the inner cavity. The signal reading module 140 and the signal analysis module 150 are mounted on the detection substrate 130. The signal reading module 140 is used to irradiate and scan the test strip 3 to read signals. The reading end of the signal reading module 140 is located inside the receiving cavity 102. The signal analysis module 150 is used to analyze the signals read by the signal reading module 140. The signal analysis module 150 is electrically connected to the signal reading module 140. The signal reading module 140 and the signal analysis module 150 are both prior arts and will not be elaborated here.

[0056] The analyzer body 1 is provided with a receiving member 160. The receiving member 160 is located inside the inner cavity of the analyzer body 1. The receiving member 160 is provided with a groove. The top of the groove is open. One side of the groove is an open end, and the side of the groove opposite to the open end is a closed end. The open end of the groove is adjacent to the test strip socket 101. The space surrounded by the receiving member 160 and the following cover body 210 forms the receiving cavity 102. In this embodiment, the receiving member 160 is a separate component and is detachably fixedly connected to the detection substrate 130. Of course, the receiving member 160 can also be processed into an integral structure with the detection substrate 130 or the lower housing 120.

[0057] As Figure 3 shown, the test strip ejection mechanism 2 includes a cover body 210, a holding member 220, an elastic member 230, and an actuator 240. The cover body 210, the elastic member 230, and the actuator 240 are sequentially located on the receiving member 160 along the direction from the test strip socket 101 to the closed end of the groove. The cover body 210 is slidably connected to the receiving member 160.

[0058] The cover body 210 covers the top opening of the groove. The inner wall of the cover body 210 is configured as part of the cavity wall of the receiving cavity 102. The cover body 210 can move relative to the analyzer body 1 between a first position adjacent to the test strip socket 101 and a second position away from the test strip socket 101. One end of the cover body 210 away from the test strip socket 101 is provided with a baffle 211 for abutting against the end of the test strip 3. The baffle 211 is located inside the receiving cavity 102.

[0059] There are at least two retaining members 220, and they are arranged opposite to each other in pairs. The retaining members 220 that cooperate with each other can switch between a separated state and an abutting state under the action of an external force. Among the retaining members 220 that cooperate with each other, one retaining member 220 is arranged on the cover body 210, and the other retaining member 220 is arranged on the surface of the container 160 or the inner wall of the lower shell 120. In this embodiment, a retaining member 220 is respectively provided on the inner side walls of the two sides of the cover body 210 as a first retaining member 2201, and a retaining member 220 is respectively provided on the outer side walls of the two sides of the container 160 as a second retaining member 2202, and the first retaining member 2201 and the second retaining member 2202 are arranged opposite to each other. Of course, the setting position and setting quantity of the first retaining member 2201 and the second retaining member 2202 can be adjusted according to the actual application scenario.

[0060] Specifically, each retaining member 220 includes a blocking portion 221 and a transition portion 222 connected to the blocking portion 221, the thickness of the end of the transition portion 222 connected to the blocking portion 221 is greater than the thickness of the end of the transition portion 222 away from the blocking portion 221, and a continuously extending inclined surface is provided between the two ends of the transition portion 222 to improve the smoothness of the switching movement between the abutting state and the separation state of the first retaining member 2201 and the second retaining member 2202. When the first retaining member 2201 and the second retaining member 2202 are in the abutting state, the blocking portions 221 of the two retaining members 220 abut against each other. When the first retaining member 2201 and the second retaining member 2202 switch from the abutting state to the separation state, the blocking portion 221 of one retaining member 220 slides along the inclined surface of the transition portion 222 of the other retaining member 220 from the connecting end of the transition portion and the blocking portion 221 to the end away from the transition portion and the blocking portion 221.

[0061] One end of the elastic member 230 abuts against the surface of the baffle 211 away from the test strip insertion port 101, and the other end of the elastic member 230 abuts against the actuator 240. Specifically, the elastic member 230 is a compression spring, one end of the compression spring abuts against the baffle 211, and the other end of the compression spring abuts against the actuator 240. The baffle 211 and the actuator 240 are both provided with a spring fixing pin 250 for sleeve-engaging the end of the compression spring. In another embodiment, the test strip ejection mechanism 2 may also not include the elastic member 230, and the actuator 240 directly abuts against the baffle 211, and the actuator 240 is manually reset from the execution position to the initial position.

[0062] The actuator 240 abuts against one end of the elastic member 230 that faces away from the baffle 211. The actuator 240 is capable of moving relative to the analyzer main body 1 between an initial position and an actuating position that causes the above-mentioned holding member 220 to switch from the abutting state to the separated state. A part of the actuator 240 extends outside the analyzer main body 1. Of course, in another embodiment, the actuator 240 may not be provided on the accommodating member 160, but may be connected to the cover 210. The operator applies a force to the actuator 240 to move the cover 210, so that the first holding member 2201 located on the cover 210 and the second holding member 2202 located on the accommodating member 160 switch from the abutting state to the separated state.

[0063] In this embodiment, specifically, the actuator 240 includes a button 241 and a slider 242 connected to the button 241. The button 241 is provided outside the analyzer main body 1 and is slidably connected to the analyzer main body 1. The button 241 is capable of sliding relative to the analyzer main body 1 in the direction of the test strip insertion port 101. A part of the slider 242 can be inserted between the first holding member 2201 and the outer side wall of the accommodating member 160 under the action of an external force, so that the first holding member 2201 and the second holding member 2202 are switched from the abutting state to the separated state. Through the button 241, the operator can conveniently operate the slider 242. Of course, in another embodiment, the slider 242 may also be configured to only contact the end of the first holding member 2201, or the slider 242 may also be configured to contact other components of the first holding member 2201, as long as it can push against the first holding member 2201 under the action of an external force to separate it from the second holding member 2203.

[0064] When the cover 210 is in the first position, the first retaining member 2201 and the second retaining member 2202 are in a separated state. After the operator inserts the test strip 3 into the analyzer main body 1 through the test strip socket 101, due to the thrust transmitted by the test strip 3 to the baffle 211, the cover 210 moves from the first position to the second position. When the cover 210 is in the second position, the elastic member 230 provides a restoring force to the cover 210 through the baffle 211, so that the cover 210 has a tendency to move from the second position to the first position. The blocking portions 221 of the first retaining member 2201 and the second retaining member 2202 are in an abutting state, so that the cover 210 is held in the second position. The elastic member 230 also provides a restoring force to the actuator 240, so that the actuator 240 is held in the initial position. After the detection is completed, the operator pushes the button 241 to move the actuator 240 from the initial position to the execution position. When the actuator 240 is in the execution position, the first retaining member 2201 and the second retaining member 2202 are switched from the abutting state to the separated state, so that the cover 210 moves from the second position to the first position under the action of the restoring force provided by the elastic member 230. The baffle 211 pushes the test strip 3 out of the analyzer main body 1 by a certain distance. At this time, there is a small frictional resistance between the test strip 3 and the wall of the accommodation cavity 102, and the operator can apply a very small external force to take out the test strip 3 from the analyzer main body 1.

[0065] In this embodiment, as Figure 4 shown, the cover 210 is provided with a first limiting member 212. The first limiting member 212 protrudes from the surface of the cover 210 adjacent to the accommodation cavity 102. The first limiting member 212 extends in the direction towards the accommodation cavity 102. The first limiting member 212 can limit the relative position between the test strip 3 and the cover 210 when the test strip 3 is located in the accommodation cavity 102. When the operator holds the handheld analyzer inserted with the test strip 3 and changes the holding direction, due to the abutting action of the first limiting member 212 on the surface of the test strip 3, the test strip 3 is not easily detached from the analyzer main body 1. As Figure 5 shown, in order to cooperate with the first limiting member 212, a limiting groove 301 is provided on the surface of the test strip 3 at a position corresponding to the first limiting member 212. When the test strip 3 is inserted into the analyzer main body 1, the first limiting member 212 abuts against the wall of the limiting groove 301.

[0066] Specifically, the first limiting member 212 includes a spring piece 2121 and a limiting block 2122. One end of the spring piece 2121 is fixedly connected to the cover 210, and the limiting block 2122 is connected to the other end of the spring piece 2121. The other end of the spring piece 2121 can move relative to the cover 210, and the limiting block 2122 extends in the direction towards the accommodation cavity 102. In this way, the limiting block 2122 can more easily disengage from the test strip 3 under the action of an external force, which is convenient for the operator to take out the test strip 3 from the test strip socket 101.

[0067] In another embodiment, both ends of the elastic piece 2121 are fixedly connected to the cover body 210. The limiting block 2122 is located at the middle position of the bottom surface of the elastic piece 2121, and the middle part of the elastic piece 2121 can move relative to the cover body 210.

[0068] In yet another embodiment, the first limiting member 212 may not include the elastic piece 2121, and the relative position of the limiting block 2122 and the cover body 210 is fixed.

[0069] In this embodiment, the cover body 210 is provided with a guiding block 213, and the accommodating member 160 is provided with a guiding groove 163. A part of the guiding block 213 is disposed in the guiding groove 163 and can slide along the guiding groove 163. When the cover body 210 is in the first position, one end of the guiding block 213 abuts against the groove wall of the guiding groove 163 adjacent to the test strip socket 101. When the cover body 210 is in the second position, the other end of the guiding block 213 abuts against the groove wall of the guiding groove away from the test strip socket 101. Through the cooperation of the guiding block 213 and the guiding groove 163, the relative sliding of the cover body 210 and the accommodating member 160 is smooth, and the sliding direction and the limit position of the cover body 210 relative to the accommodating member 160 are restricted. Of course, the positions of the guiding block 213 and the guiding groove 163 on the cover body 210 and the accommodating member 160 can be interchanged.

[0070] In this embodiment, second limiting members 161 protruding from the surface are provided on two opposite side portions of the accommodating member 160. Two second limiting members 161 are provided on each side surface. One of the second limiting members 161 abuts against the guiding block 213 to prevent the cover body 210 from moving from the second position to the first position when the cover body 210 is in the first position, and the other second limiting member 161 abuts against the guiding block 213 to prevent the cover body 210 from moving from the first position to the second position when the cover body 210 is in the second position.

[0071] In another embodiment, only one second limiting member 161 may be provided on each side surface of the accommodating member 160, so as to only prevent the cover body 210 from moving from the second position to the first position, or only prevent the cover body 210 from moving from the first position to the second position. Or, the accommodating member 160 may not be provided with the second limiting member 161, and the limiting of the cover body 210 in the first position and the second position is achieved only through the cooperation of the guiding block 213 and the guiding groove 163.

[0072] In this embodiment, the bottom of the guiding groove 163 has an inclined surface, and the inclination direction of the inclined surface forms an acute angle with the direction in which the accommodating member 160 extends from the test strip socket 101 towards the baffle 211. When the cover body 210 moves from the first position to the second position, the guiding block 213 moves along the inclined surface of the bottom of the guiding groove 163, driving the cover body 210 to gradually approach the accommodating member 160, so that the distance between the cover body 210 and the accommodating member 160 gradually decreases. The inner wall of the top of the cover body 210 presses the test strip 3 towards the bottom of the groove of the accommodating member 160, thereby further restricting the relative position between the test strip 3 and the cover body 210, and it is more difficult for the test strip 3 to come out of the analyzer body.

[0073] In this embodiment, referring again to Figure 3 , the dialing block 242 includes a dialing block body 2421 and a protruding portion 2422 provided on the surface of the dialing block body 2421. The protruding portion 2422 extends towards the holding member 220, and the maximum thickness of the protruding portion 2422 is greater than the minimum distance between the inner side portion of the first holding member 2201 and the outer side wall of the accommodating member 160 opposite thereto. In this way, when the protruding portion 2422 is inserted between the first holding member 2201 and the outer side wall of the accommodating member 160, as the protruding portion 2422 moves, the first holding member 2201 is pushed and moves in a direction away from the outer side wall of the accommodating member 160, and the first holding member 2201 and the second holding member 2202 are switched from the abutting state to the separated state.

[0074] In this embodiment, as Figure 6 shown, a limiting hole 111 is provided on the surface of the upper housing 110, and a part of the button 241 is inserted into the limiting hole 111. The limiting hole 111 is used to limit the sliding displacement of the button 241 relative to the analyzer body 1.

[0075] In this embodiment, as Figure 7 shown, the analyzer body 1 is provided with a trigger unit 170 for generating a trigger signal. The trigger unit 170 has a trigger switch 171, and the cover body 210 is provided with a trigger bump 214. When the cover body 210 is in the second position, the trigger bump 214 abuts against the trigger switch 171, so that the trigger unit 170 generates a trigger signal. The trigger unit 170 is electrically connected to the signal analysis module 150. By generating a trigger signal and having the signal analysis module 150 read the trigger signal, the handheld analyzer can immediately know that the test strip 3 is inserted and in place at a preset position within the analyzer body 1, so as to perform subsequent operations.

[0076] An embodiment of the present invention also discloses a handheld analysis device, including a test strip 3 and the above-mentioned handheld analyzer. The surface of the test strip 3 is provided with a limiting groove 301 that matches the first limiting member 212.

[0077] An embodiment of the present invention also discloses an analysis method using the handheld analyzer described above. The method specifically includes the following steps:

[0078] Insert the test strip 3 into the test strip socket 101, and move the test strip 3 along the analyzer body 1 towards the end of the accommodation cavity 102 away from the test strip socket 101;

[0079] Make the test strip 3 abut against the baffle 211, the test strip 3 stops moving relative to the cover body 210, maintain the movement trend of the test strip 3 relative to the analyzer body 1, and make the cover body 210 move relative to the analyzer body 1 from the first position adjacent to the test strip socket 101 to the second position away from the test strip socket 101. At least one retaining member 220 on the cover body 201 and at least another retaining member 220 on the analyzer body 1 are switched from the separated state to the abutting state;

[0080] Continue the movement trend of the test strip 3 until the cover body 210 reaches the second position, the analyzer body 1 obtains a trigger signal, and at least one retaining member 220 on the cover body 201 and at least another retaining member 220 on the analyzer body 1 are simultaneously switched to the abutting state;

[0081] Execute the detection action on the test strip 3 through the analyzer body 1;

[0082] After the detection is completed, shift the actuator 240 from the initial position relative to the analyzer body 1 to the execution position where at least two retaining members 220 are switched from the abutting state to the separated state, so that the baffle 211 pushes against the test strip 3 and moves along the analyzer body 1 in the direction of the test strip socket 101 for a certain distance;

[0083] Withdraw the test strip 3 from the test strip socket 101.

[0084] In this embodiment, after the test strip 3 is inserted into the test strip socket 101, the analysis method further includes the following steps: make the first limiting member 212 abut against the surface of the test strip 3.

[0085] In this embodiment, the analyzer main body 1 obtains a trigger signal through the following steps: the trigger bump 214 abuts against the trigger switch 171, so that the trigger unit 170 generates a trigger signal. Specifically, during the movement of the cover body 201 from the first position to the second position, the trigger bump 214 gradually contacts and covers the trigger switch 171. When the trigger switch 171 is completely covered, the trigger unit 170 generates a trigger signal. During the process that the actuator 240 is displaced from the initial position relative to the analyzer main body 1 to the execution position where at least two holding members 220 are switched from the abutting state to the separated state, the trigger bump 214 gradually releases the coverage of the trigger switch 171. Of course, in another embodiment, the trigger bump 214 may also be configured not to cover the trigger switch 171, but only to abut against the trigger switch 171 so that the trigger unit 170 generates a trigger signal.

[0086] Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
