Exit mechanism and detector

Abstract

The embodiments of this specification provide an exit mechanism and a detector. The exit mechanism includes a housing, a sliding member, and a stopper disposed within the housing. The sliding member is provided with a guide structure that can engage with the stopper in relative motion. The guide structure has a first position and a second position relative to the stopper: when the guide structure moves to the first position, the stopper and the sliding member form a limiting engagement; when the guide structure moves to the second position, the stopper and the sliding member release the limiting engagement. The exit mechanism can automatically push the insert out of the exit mechanism through the relative motion between the sliding member and the stopper, thereby reducing the difficulty of the insert detaching from the detector and making it easier for the insert to exit the detector.

Description

Technical Field

[0001] This specification relates to the field of medical equipment, and in particular to an exit mechanism and a detector. Background Art

[0002] In disease diagnosis, a medical tester can refer to an instrument used to automatically obtain test results from a test plate. During use, a test plate containing samples such as urine, saliva, and blood must be inserted into the tester for scanning and analysis. Once the test results are obtained, the test plate must be removed from the tester. However, existing test plates typically have a protective cover on the handheld portion to prevent the sample from contaminating fingers. This can easily cause the cover to separate from the test plate when the test plate is removed, leaving the test plate inside the tester. This can make it difficult to remove the test plate. Therefore, a mechanism is needed to facilitate the automatic removal of the test plate. Summary of the Invention

However, if other terms can achieve the same purpose, the terms may be replaced by other expressions.

[0033] As used in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not refer to the singular but also include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list.

Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0035] The present application provides an ejection mechanism for automatically ejecting a test plate from a tester, making it easier to remove the test plate from the tester and resolving the technical issue of the test plate being difficult to remove from the tester. In some embodiments of the present disclosure, the automatic ejection mechanism can be applied not only to medical testers but also to devices in other fields, such as computer card readers, shared power banks, and self-service cash registers.

[0036] Figure 1 It is a structural diagram of the exit mechanism shown in some embodiments of this specification. Figure 2 is an exploded view of an ejection mechanism according to some embodiments of this specification. Figure 3 1 is an exploded view of the first mounting plate 131 and the sliding member 2 according to some embodiments of this specification.

[0037] like Figure 1 and Figure 2 As shown, an embodiment of the present specification provides an ejection mechanism, which can automatically eject an insert, and the insert can be a detection board, an electronic card, etc. The ejection mechanism includes a shell 1, and a sliding member 2 and a stopper 3 arranged in the shell 1, the stopper 3 is fixed in the shell, and the sliding member 2 can be movably arranged in the shell 1 relative to the stopper 3, wherein the sliding member 2 moves in the insertion and extraction direction of the insert relative to the shell 1. A guide structure 21 is provided on the sliding member 2, and the guide structure 21 can be connected to the stopper 3 for relative movement, and the guide structure 21 can guide the sliding member 2 to move in the insertion and extraction direction of the insert relative to the stopper 3. In some embodiments, the guide structure 21 can be a slide groove 211, and the stopper 3 can be connected to the slide groove 211 for relative movement. For details about the guide structure 21, please refer to Figure 6A and Figure 6B and its related descriptions.

[0038] In some embodiments, the guide structure 21 has a first position and a second position relative to the stopper 3: when the guide structure 21 moves to the first position, the stopper 3 forms a limiting fit with the sliding member 2, and at this time the sliding member 2 is limited by the stopper 3 in the first position, that is, the guide structure 21 will not slide to the second position without the action of external force; when the guide structure 21 moves to the second position, the stopper 3 and the sliding member 2 are released from the limiting position, and at this time the sliding member 2 is not limited by the stopper 3, so that the sliding member 2 can move relative to the stopper 3. In the application example of the exit mechanism, an insert such as a detection board or an electronic card is inserted into the exit mechanism, and the exit mechanism can automatically push the insert (not shown in the figure) out of the exit mechanism through the relative movement between the sliding member 2 and the stopper 3, thereby reducing the difficulty of the insert detaching from the detector and making it easier for the insert to exit the detector. For the relative movement relationship between the stopper 3 and the sliding member 2, please refer to 7A to 7D and its related descriptions.

[0039] In some embodiments, as Figure 1 As shown, a housing 1 further includes a cavity 11, which may be a chamber for accommodating inserts such as a detection board and an electronic card. In some embodiments, one end of the cavity 11 has an opening 12 for allowing the insert to enter and exit, and the opening 12 is adapted to the cross-section of the insert.

[0040] In some embodiments, combined Figure 1 and Figure 2 , the sliding member 2 can be configured to be able to slide relative to the accommodating cavity 11. In some embodiments, the sliding member 2 can be configured to slide back and forth between the opening 12 of the accommodating cavity 11 and the end of the accommodating cavity 11 away from the opening 12, that is, the sliding direction of the sliding member 2 is the same as the insertion direction and withdrawal direction of the insert. Specifically, the insert is inserted into the accommodating cavity 11 from the opening 12, and can abut against the sliding member 2 during the process of the insert entering the accommodating cavity 11, so that the sliding member 2 can move from the opening 12 position of the accommodating cavity 11 to the end of the accommodating cavity 11 away from the opening 12 under the push of the insert; when the sliding member 2 slides from the end of the accommodating cavity 11 away from the opening 12 toward the opening 12, the sliding member 2 pushes the insert to withdraw from the opening 12 of the accommodating cavity 11.

[0041] In some embodiments, as Figure 1 and Figure 3 As shown, the sliding member 2 includes a protrusion 22, one end of which is fixed to the sliding member 2, and the other end of which extends into the interior of the accommodating cavity 11 and abuts against the bottom of the insert, wherein the bottom of the insert may refer to the end of the insert that first enters the accommodating cavity 11 when the insert enters the accommodating cavity 11 from the opening 12. When the insert is inserted into the accommodating cavity 11, it can push the protrusion 22 to slide toward the end of the accommodating cavity 11 away from the opening 12, thereby driving the sliding member 2 to slide from the opening 12 toward the end of the accommodating cavity 11 away from the opening 12; during the process of the sliding member 2 sliding from the end of the accommodating cavity 11 away from the opening 12 toward the opening 12, the protrusion 2 pushes the insert to exit from the opening 12 of the accommodating cavity 11.

[0042] In some embodiments, as Figure 1 and Figure 2 As shown, the housing 1 of the ejection mechanism includes a mounting member and an outer shell. The sliding member 2 and the stopper 3 are both arranged on the mounting member, and the mounting member is encapsulated in the outer shell.

[0043] In some embodiments, the housing includes a main body 141 and a back cover 142. The main body 141 has a chamber for accommodating the mounting parts. The back cover 142 is detachably connected to the main body 141. For example, the back cover 142 and the main body 141 can be connected by snap-on connection, threaded connection, or other connection methods. The back cover 142 is used to encapsulate the mounting parts in the chamber of the main body 141 to achieve dust-proof and waterproof effects.

[0044] In some embodiments, as Figure 3 and Figure 4 As shown, the mounting member can be designed or constructed based on the installation requirements of the slider 2 and the stopper 3. For example, the mounting member includes a first mounting plate 131 and a second mounting plate 132. The first mounting plate 131 is used to install components such as the slider 2, and the second mounting plate 132 is used to install components such as the stopper 3. In some embodiments, the first mounting plate 131 and the second mounting plate 132 are detachably connected, for example, by bolts, snaps, etc. In some embodiments, a certain gap is maintained between the side wall of the first mounting plate 131 and the inner wall of the main body 141 to form a receiving cavity 11 capable of accommodating an insert. A corresponding opening 12 is formed on the side wall of the main body 141, and the insert can enter the receiving cavity 11 through the opening 12.

[0045] like Figures 1 to 3 As shown, in some embodiments, a limiting groove 1311 is formed on the first mounting plate 131. The limiting groove 1311 extends linearly from the end of the accommodating chamber 11 away from the opening 12 to the opening 12 of the accommodating chamber 11. The sliding member 2 is embedded in the limiting groove 1311, and the sliding member 2 can slide back and forth in the limiting groove 1311. In some embodiments, an avoidance long hole 1312 is formed in the limiting groove 1311. The avoidance long hole 1312 extends linearly from the end of the accommodating chamber 11 away from the opening 12 to the opening 12 of the accommodating chamber 11. The avoidance long hole 1312 is used to avoid the protrusion 22 of the sliding member 2. The protrusion 22 of the sliding member 2 passes through the avoidance long hole 1312 and extends into the interior of the accommodating chamber 11.

[0046] Figure 4 It is an exploded view of the first mounting plate 131 and the sliding member 2 from another perspective according to some embodiments of this specification.

[0047] like Figure 4As shown, in some embodiments, the exit mechanism further includes a guide rod 4, both ends of which are fixed to the housing 1. In some embodiments, the guide rod 4 is fixed in the limiting groove 1311 of the first mounting plate 131, and the guide rod 4 is extended along the sliding direction of the slider 2. In some embodiments, the slider 2 includes two limiting holes 23, and the two limiting holes 23 are respectively located on both sides of the guide structure 21 of the slider 2. A guide rod 4 is provided corresponding to each limiting hole 23, and the guide rod 4 passes through the limiting hole 23 so that the slider 2 is sleeved on the guide rod 4 and slides back and forth along the guide rod 4. By providing the guide rod 4, the slider 2 can be prevented from disengaging from the limiting groove 1311, so that the slider 2 always remains in the limiting groove 1311.

[0048] Combine Figure 1 and Figure 4 As shown, in some embodiments, the exit mechanism further includes an elastic member 5, which is used to apply an elastic force to the sliding member 2 toward the opening 12. In some embodiments, the elastic member 5 includes a spring, which is sleeved on the guide rod 4 and disposed in the limiting groove 1311. One end of the spring abuts against the end of the limiting groove 1311 away from the opening 12, and the other end abuts against the sliding member 2. When the sliding member 2 moves from the opening 12 of the accommodating chamber 11 to the end of the accommodating chamber 11 away from the opening 12, the spring is compressed and accumulates force until the stop member 3 and the sliding member 2 form a limiting fit. When the stop member 3 and the sliding member 2 are released from the limiting fit, the sliding member 2 slides toward the opening 12 of the accommodating chamber 11 under the action of the elastic restoring force of the spring.

[0049] Figure 5 1 is a schematic structural diagram of the second mounting plate 132 and the stopper 3 according to some embodiments of this specification.

[0050] In some embodiments, as Figure 4 and Figure 5 As shown, the stopper 3 includes a hook 31, which is configured as an N-shaped structure with two bent ends. The hook 31 includes a sliding end 311 and a fixed end 312. The sliding end 311 of the hook 31 is used to connect with the guide structure 21 of the slider 2, while the fixed end 312 of the hook 31 is connected to the housing 1. For example, the fixed end 312 can be fixed to a mounting member. In some embodiments, the hook 31 and the slider 2 are respectively located on opposite sides of a second mounting plate 132. The second mounting plate 132 includes a first through-hole 1321 and a second through-hole 1322. The sliding end 311 of the hook 31 passes through the first through-hole 1321 to connect with the slider 2 on the other side of the second mounting plate 132, while the fixed end 312 of the hook 31 passes through the second through-hole 1322 to be fixedly connected to the first mounting plate 131. By providing the second mounting plate 132 to separate the hook 31 and the slider 2, the slider 2 does not affect the stability of the hook 31 during its movement.

[0051] Figure 6A It is a schematic structural diagram of the sliding member 2 shown in some embodiments of this specification. Figure 6B It is a partial schematic diagram of the sliding member 2 shown in some embodiments of this specification.

[0052] like Figure 6A As shown, in some embodiments, the guide structure 21 of the slider 2 includes a slide groove 211 and a limiting structure 212. The limiting structure 212 is disposed within the slide groove 211. The limiting structure 212 may be a structure for forming a locking engagement with the stopper 3. The limiting structure 212 can limit the movement of the slider 2 relative to the stopper 3 toward the opening 12 of the accommodating cavity 11. In some embodiments, the limiting structure 212 is configured as an elongated protrusion. When the stopper 3 moves to the first position, the limiting structure 212 is locked. That is, the stopper 3 is locked on the limiting structure 212, preventing the stopper 3 from moving along the slide groove, thereby forming a limiting engagement between the slider 2 and the stopper 3.

[0053] In some embodiments, combined Figure 5 and Figure 6A As shown, the sliding end 311 of the hook 31 is slidably connected to the slide groove 211, and the hook 31 is configured to selectively engage or disengage with the limiting structure 212. In some embodiments, when the insert pushes the slider 2 to the end of the accommodating cavity 11 away from the opening 12 via the protrusion 22, the hook 31 engages with the limiting structure 212, so that the slider 2 remains in the position at the end of the accommodating cavity 11 away from the opening 12; when the insert needs to be withdrawn, the hook 31 disengages from the limiting structure 212, thereby releasing the constraint of the hook 31 on the slider 2. The slider 2 slides toward the opening 12 of the accommodating cavity 11 under the action of the elastic member 5, thereby achieving automatic withdrawal of the insert from the accommodating cavity 11.

[0054] In some embodiments, the limiting structure 212 is configured as an elongated strip, and its extension direction is parallel to the sliding direction of the slider 2. In some embodiments, the limiting structure 212 can also be configured as a dot-shaped protrusion, a curved protrusion, etc. In some embodiments, as shown in FIG6 , a recessed notch 2121 is formed at one end of the limiting structure 212. The recessed notch 2121 is used to engage with the retractor 31, and the recessed direction of the recessed notch 2121 is toward the other end of the limiting structure 212. When the retractor 31 slides to the recessed notch 2121, the sliding end 311 of the retractor 31 will slide into the recessed notch 2121 to engage, thereby limiting the sliding of the slider 2 toward the exit of the accommodating chamber 11.

[0055] like Figure 6A and Figure 6BAs shown, in some embodiments, the slide 211 includes a first slide 2111, a second slide 2112, and a transition slide 2113 located between the first slide 2111 and the second slide 2112. In some embodiments, the first slide 2111 and the second slide 2112 are long strip slides separated by a limiting structure 212. One end of the first slide 2111 is connected to the transition slide 2113, and the other end is connected to the second slide 2112. The first slide 2111 is used to guide the stopper 3 to slide to the transition slide 2113; one end of the second slide 2112 is connected to the transition slide 2113, and the other end is connected to the first slide 2111. The first slide 2111 is used to guide the stopper 3 to slide to the transition slide 2113, and the second slide 2112 is used to guide the stopper 3 to slide from the transition slide 2113 to the first slide 2111 through the second slide 2112. In some embodiments, the transition slide 2113 may be a slide close to the recessed notch 2121 of the limiting structure 212 . The transition slide 2113 may be constructed in various shapes such as an arc shape, a V shape, or a U shape.

[0056] In some embodiments, the transition slide 2113 is used to guide the stopper 3 to slide unidirectionally from the first slide 2111 to the second slide 2112 , and the stopper 3 and the sliding member 2 form a limiting fit at the transition slide 2113 .

[0057] In some embodiments, a first step 2114 and a second step 2115 are provided in the transition slide 2113 and decrease in sequence from the first slide 2111 to the second slide 2112 .

[0058] In some embodiments, the first step 2114 is used to guide the stopper 3 to slide onto the second step 2115. In some embodiments, the first step 2114 includes a bottom surface and side surfaces. The bottom surface of the first step 2114 is lower than the bottom surface of the first slideway 2111, and the side surfaces of the first step 2114 extend from the recessed notch 2121 of the retaining structure 212 to the sidewalls of the transition slideway 2113. When the stopper 3 slides from the first slideway 2111 onto the first step 2114, the side surfaces of the first step 2114 can guide the stopper 3 to slide toward the recessed notch 2121 and onto the second step 2115.

[0059] In some embodiments, the second step 2115 is used to guide the stopper 3 into the second slideway 2112. In some embodiments, the second step 2115 includes a bottom surface and side surfaces. The bottom surface of the second step 2115 corresponds to the recessed notch 2121. The bottom surface of the second step 2115 is lower than the bottom surface of the first step 2114 and higher than the bottom surface of the second slideway 2112. The side surfaces of the second step 2115 extend from the intersection of the recessed notch 2121 and the first step 2114 to the sidewalls of the transition slideway 2113. When the stopper 3 slides from the first step 2114 onto the second step 2115, the stopper 3 and the slider 2 form a retaining engagement, i.e., the sliding end 311 of the hook 31 engages the recessed notch 2121 of the retaining structure 212. When the sliding member 2 continues to slide toward the end of the accommodating cavity 11 away from the opening 12, the side guide of the second step 2115 slides the stop member 3 into the second slide 2112. At this time, the second slide 2112 has no constraint on the stop member 3, and the sliding member 2 slides toward the opening 12 of the accommodating cavity 11 under the elastic restoring force of the elastic member 5.

[0060] In some embodiments, as Figure 6A As shown, the first slide 2111 and the second slide 2112 merge at one end away from the transition slide 2113 to extend into the third slide 2117. The second slide 2112 is configured as a ramp 2116 that gradually rises from the transition slide 2113 to the third slide 2117. The height of the ramp 2116 at one end near the third slide 2117 is at least flush with or higher than the first slide 2111. Thus, when the stopper 3 slides from the second slide 2112 toward the third slide 2117, it returns to the first slide 2111.

[0061] In some embodiments, one end of the slope 2116 close to the third slide 2117 protrudes from the third slide 2117, that is, a cross-section is formed at the intersection of the slope 2116 and the third slide 2117. In this way, when the stop member 3 slides from the third slide 2117 toward the first slide 2111 and the second slide 2112, the stop member 3 will not slide into the second slide 2112 under the stop of the cross-section of the slope 2116, but will only slide into the first slide 2111, thereby ensuring the one-way sliding of the stop member 3 in the slide groove 211.

[0062] In some embodiments, as Figures 5 to 6BAs shown, the ejection mechanism further includes a spring clip 7, one end of which is fixed to the housing 1, and the other end of which presses against the hook 31 to maintain the hook 31 in the chute 211. In some embodiments, the spring clip 7 may be a sheet-like structure having a certain degree of elasticity, one end of which is fixed to the second mounting plate 132, and the other end of which presses against the hook 31. Because the chute 211 is provided with steps and slopes 2116 of varying heights, when the hook 31 slides in the chute 211, it rises and falls with the steps and slopes 2116. The pressing action of the spring clip 7 on the hook 31 ensures that the sliding end 311 of the hook 31 always maintains contact with the bottom surface of the chute 211 of varying heights.

[0063] Figure 7A It is a structural schematic diagram of the sliding member 2 and the stop member 3 at the third slideway 2117 according to some embodiments of this specification. Figure 7B 2 is a schematic structural diagram of the sliding member 2 and the stop member 3 at the first step 2114 according to some embodiments of this specification.

Figure 7D 2 is a schematic structural diagram of the sliding member 2 and the stopper 3 at the second slideway 2112 according to some embodiments of this specification.

[0064] In some embodiments, as 7A to 7D As shown, when the ejection mechanism is used, the process of inserting the insert (such as a detection board, an electronic card) into the accommodating cavity 11 and ejecting the insert (such as a detection board, an electronic card) from the accommodating cavity 11 is as follows:

[0065] like Figure 7A The state shown is a state where the insert is not inserted or a state where the insert has just been inserted. Figure 7A In the state shown, the sliding member 2 is located at one end close to the opening 12 of the accommodating cavity 11, the sliding end 311 of the hook 31 is located in the third sliding groove 211, and the elastic member 5 is in a natural state without being subjected to external forces.

[0066] like Figure 7B The state shown is a state in which the insert is inserted into the end of the accommodating cavity 11 away from the opening 12 . Figure 7A The status shown changes to Figure 7BThe process of the state shown includes manually pushing the insert into the accommodating cavity 11 from the opening 12. After the bottom of the insert enters the accommodating cavity 11, it can abut against the protrusion 22, pushing the protrusion 22 to drive the slider 2 toward the end of the accommodating cavity 11 away from the opening 12. During the movement of the slider 2, the sliding end 311 of the hook 31 slides within the third slide groove 211 toward the first slide groove 211 and continues to slide onto the first step 2114. At this point, the insert is inserted into the end of the accommodating cavity 11 away from the opening 12, and the elastic member 5 abuts between the slider 2 and the first mounting plate 131, in a compressed and force-storing state.

[0067] like Figure 7C The state shown is a state in which the insert is held in the accommodation cavity 11 . Figure 7B The status shown changes to Figure 7C The process of the state shown includes: after the insert is inserted into the end of the accommodating cavity 11 away from the opening 12, the thrust of pushing the insert is released, and the sliding member 2 moves toward the opening 12 of the accommodating cavity 11 under the elastic force of the elastic member 5. When the sliding member 2 moves, the sliding end 311 of the hook 31 slides down into the second step 2115 under the guidance of the side of the first step 2114, and is locked by the concave notch 2121 of the limiting structure 212 corresponding to the second step 2115. At this time, the sliding member 2 is relative to the Figure 7B The state moves a small distance, and the elastic member 5 is still maintained in the compressed and stored state. The elastic member 5 applies a thrust toward the opening 12 of the accommodating chamber 11 to the sliding member 2, and the sliding end 311 of the hook 31 applies a pulling force toward the end of the accommodating chamber 11 away from the opening 12 to the sliding member 2 through the recessed notch 2121. The thrust and pulling forces are balanced with each other, so that the sliding member 2 is maintained in a position close to the end of the accommodating chamber 11 away from the opening 12.

[0068] like Figure 7D The state shown is an intermediate state where the insert is about to exit the accommodating cavity 11 . Figure 7C The status shown changes to Figure 7D The process of the state shown includes: when the insert needs to be withdrawn, the insert is manually pushed to move toward the end of the accommodating cavity 11 away from the opening 12, and the insert drives the sliding member 2 to slide toward the end of the accommodating cavity 11 away from the opening 12 through the protrusion 22. At this time, the sliding end 311 of the hook 31 slides from the second step 2115 to the second slide 2112. Since the second slide 2112 does not limit the sliding end 311 of the hook 31, the sliding member 2 can move toward the opening 12 of the accommodating cavity 11 under the action of the elastic restoring force of the elastic member 5, and the sliding end 311 of the hook 31 slides from the second slide 2112 to the third slide 2117 again. The sliding member 2 slides again to the state shown in FIG. Figure 7AThe device is stopped in the state shown. During this process, the insert is pushed out of the receiving cavity 11 by the protrusion 22 of the slider 2, thereby achieving automatic withdrawal of the insert. By using the different states between the slider 2 and the hook 31 of the withdrawal mechanism, the insert can be automatically withdrawn from the receiving cavity 11, making it easier for the insert to be completely removed from the receiving cavity 11 and improving detection efficiency.

[0069] Figure 8 It is a structural schematic diagram of the insert and the ejection mechanism according to some embodiments of this specification.

[0070] An embodiment of the present specification also provides a detector, which includes an exit mechanism as shown in any of the above embodiments.

[0071] In some embodiments, the detector also includes a body (not shown in the figure), which refers to a device that can be used to detect the signal of the insert 8. For example, for a detector in the medical field, the body can be a device that can detect and identify the reaction signal displayed on the detection board, such as a plug-in pregnancy test pen, a fluorescence meter, a handheld drug detector and other equipment.

[0072] like Figure 8 As shown, in some embodiments, the ejection mechanism is detachably mounted on the housing. The housing 1 of the ejection mechanism has an observation window 6, one side of which is connected to the receiving cavity 11 and the other side of which is aligned with the detection port of the housing. Thus, the housing reads the information of the insert 8 in the receiving cavity 11 through the observation window 6, which improves reading accuracy compared to manual reading.

[0073] The beneficial effects that may be brought about by the embodiments of the present application include but are not limited to: (1) after the detection board, electronic card and other inserts are inserted into the exit mechanism, the exit mechanism can automatically push the insert out of the exit mechanism through the relative movement between the sliding member and the stopper, thereby reducing the difficulty of the insert from being separated from the detector and making it easier for the insert to be removed from the detector; (2) the first mounting plate and the second mounting plate are encapsulated by the main body and the back cover of the shell, which can play a role in dustproof and waterproof; (3) by setting a guide rod, the sliding member can be prevented from being separated from the limit groove, so that the sliding member is always kept in the limit groove; (4) by the different states of the pull hook of the exit mechanism sliding in the slide groove, the insert is kept in the accommodating cavity, and the insert can also be automatically removed from the accommodating cavity, which is fully functional and improves the detection efficiency. It should be noted that different embodiments may have different beneficial effects. In different embodiments, the beneficial effects that may be produced may be any one or a combination of the above, or any other possible beneficial effects.
