Description

Technical Field

[0001] The present application relates to the field of analytical instruments, in particular to a docking assembly for a reagent kit and a medical testing device. Background Art

[0002] Medical testing devices are generally equipped with a detachable reagent kit. While using the reagents in the reagent kit to perform sample testing, the detachable reagent kit can also conveniently achieve reagent supplementation or replacement. Currently, common medical testing devices generally connect the reagent kit and the test card through a fluid passage in the device main body, and use a valve body provided in the fluid passage of the device main body to control the on / off of the reagent kit and the test card, so as to facilitate the replacement and disassembly of the reagent kit.

[0003] However, since the fluid passage provided in the device main body needs to be used multiple times, in order to ensure the normal operation of the device main body, there are maintenance costs for the fluid passage and the valve body. And replacing the reagent kit requires disassembling and assembling the interface between the device main body and the reagent kit. After removing the reagent kit for replacement multiple times, there may be many problems such as leakage and difficult docking at this interface, which have an adverse impact on the durability and stability of the medical testing device. Summary of the Invention

[0004] The technical problem to be solved by the present application is how to provide a docking assembly for a reagent kit and a medical testing device, which can separately set the fluid passage in the reagent kit and improve the durability of the medical testing device.

[0005] The present application provides a medical testing device, including a device main body, an execution component, and a reagent kit. The execution component is installed on the device main body, and the reagent kit is replaceably docked with the device main body. The reagent kit includes a box body and a docking assembly. A first installation space is formed inside the box body, and a first opening is provided on one side of the first installation space close to the execution component. The docking assembly includes a docking main body and a movable valve body. The docking main body has a cavity and a second opening and a third opening communicating with the cavity. The second opening is used to dock with a liquid bag / external space, and the third opening is used to connect to a test card through a fluid passage in the reagent kit. The movable valve body is located in the cavity, and the movable valve body selectively opens / seals the second opening / the third opening under the action of the execution component to control the connection or closing of the liquid bag / external space and the fluid passage.

[0006] Different from the prior art, the present application discloses a docking assembly for a reagent kit and a medical testing device, which can connect the test card and the liquid bag / external space by using a fluid passage separately provided in the reagent kit, and use a movable valve body provided inside the reagent kit to control whether to introduce fluid into the test card under the drive of an external force, integrating the fluid passage structure of the medical testing device into the reagent kit, reducing the sealing requirement and maintenance cost of the device main body, and improving the stability and durability of the medical testing device.

[0018] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the sake of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0019] The terms "first", "second", etc. in the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "provided with" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0020] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] With the increasing progress of analysis technology, medical detection devices generally come with detachable integrated reagent kits, which makes it more convenient to replenish or replace reagents and gases in medical detection devices. However, due to the detachable nature of the reagent kit, the sealing performance at the docking joints between the reagent kit and the test card, medical detection device, and / or valve body, as well as the maintenance of the fluid passage in the main body of the medical detection device, become issues that need to be considered.

[0022] Since there are many sensitive detection devices in the main body of the medical detection device, it is very troublesome to disassemble, maintain, or replace them. The liquid path and valve body provided in the device main body are also not convenient to maintain and cannot be replaced as frequently as the reagent kit. Once these parts are damaged, there will not only be leakage problems, but also potential equipment damage, resulting in huge maintenance costs. For the docking interfaces of the liquid path between the reagent kit and the device main body, and between the device main body and the test card, since both the reagent kit and the test card are consumables, and the docking interface on the device main body side is difficult to replace easily, it will inevitably age gradually after multiple uses, resulting in problems such as decreased sealing performance and difficult assembly, which is not conducive to the stability and durability of the medical detection device.

[0023] How to provide a docking component and a medical detection device for a kit, reduce the probability of failures at the interface between the kit and the device main body, and improve the stability and durability of the medical detection device is a major problem that this application aims to solve.

[0024] Refer to Figure 1 , 2 , 3, 10, Figure 1 is a schematic structural view of an embodiment of the medical detection device of this application. Figure 2 is a schematic cross-sectional structural view of an embodiment of the medical detection device of this application. Figure 3 is Figure 2 an enlarged schematic structural view of area A in Figure 10 is a schematic fluid passage structure view of an embodiment of the medical detection device of this application. This application provides a docking component 16 for a kit 1, including a docking main body 162 and a movable valve body 163. The docking main body 162 has a cavity 1622, a second opening 1623 and a third opening 1624 communicating with the cavity 1622. The second opening 1623 is used to dock with a liquid bag / outer space, and the third opening 1624 is used to connect to a test card 3 through a fluid passage 11 in the kit 1. The movable valve body 163 is located in the cavity 1622. The movable valve body 163 selectively opens / seals the second opening 1623 / the third opening 1624 under the action of an external force outside the fluid passage 11 to control the communication or closing of the liquid bag / outer space and the fluid passage 11.

[0025] Among them, the kit 1 is replaceably docked with the device main body 2 of the medical detection device. A liquid bag containing a reagent can be integrated in the kit 1. A fluid passage 11 is provided inside the kit 1, and the reagent in the liquid bag or the gas in the outer space can flow into the test card 3 through the fluid passage 11. Specifically, the fluid passage 11 has a fluid outlet 111 and at least one fluid inlet 112. The fluid outlet 111 is used to connect to the test card 3, and the fluid inlet 112 is used to connect to the liquid bag and / or the outer space.

[0026] Optionally, the external force for driving the movable valve body 163 can be applied by an actuator assembly 21. The actuator assembly 21 can be installed on the device main body 2 for selectively driving the movable valve body 163 to open or close. The actuator assembly 21 provided on the device main body 2 can be reused. Even when the old kit 1 is replaced with a new kit 1, the actuator assembly 21 can still normally perform the work of driving the movable valve body 163. Optionally, the energy of the actuator assembly 21 installed on the device main body 2 can be provided by the circuit of the medical detection device.

[0027] Optionally, the actuator assembly 21 can also be provided on the replaceable kit 1. Further, the actuator assembly 21 provided on the kit 1 can be powered by an energy storage device such as a battery, or can be connected to the device main body 2 by using components such as electrical contacts and wires.

[0028] Optionally, refer to Figure 4 , 5 , 6, 7, Figure 4 are schematic structural diagrams of the docking component and the execution component in an embodiment of the medical detection device of the present application. Figure 5 is a schematic cross-sectional structural diagram of the docking component and the execution component in an embodiment of the medical detection device of the present application. Figure 6 is the first schematic cross-sectional structural diagram of the docking component of the present application. Figure 7 is the second schematic cross-sectional structural diagram of the docking component of the present application. The docking component 16 may further include a spacer 164. The spacer 164 is disposed outside the third opening 1624 of the docking body 162, wrapping the area of the outside of the docking body 162 having the third opening 1624. The area of the outside of the docking body 162 wrapped by the spacer 164 or the spacer 164 has a diversion hole 1643 connecting to the fluid passage 11. The area of the spacer 164 corresponding to the third opening 1624 is a transmission part 1641. The transmission part 1641 is used to receive the force outside the spacer 164 and deform under the force to abut against the movable valve body 163.

[0029] Specifically, there are various ways to drive the movable valve body 163 by an external force. For example, if it is controlled by an electrical signal, the transmission part 1641 can conduct the electrical signal; for another example, if it is controlled by a magnetic force, the transmission part 1641 can conduct magnetism; or if it is controlled by mechanical transmission, the transmission part 1641 can be in transmission connection with the movable valve body 163 under the action of an external force, so as to conduct the force to the movable valve body 163.

[0030] The transmission part 1641 can be a flexible component. The side of the transmission part 1641 facing away from the third opening 1624 deforms in the direction of the third opening 1624 under the force, so as to abut against and push the movable valve body 163 to move, so that the movable valve body 163 blocking the third opening 1624 leaves the third opening 1624. After the external force is released, the movable valve body 163 can move back to the position blocking the third opening 1624, and the transmission part 1641 can be restored under the push of the movable valve body 163 and be spaced from the third opening 1624.

[0031] Further, the transmission part 1641 can also be an elastic component. After the external force is released, the transmission part 1641 can be restored by its own elasticity and be spaced from the third opening 1624.

[0032] Such as Figures 5 to 7As shown, the transmission part 1641 of the isolation chamber can have various profile shapes. Specifically, when the movable valve body 163 seals the third opening 1624, the transmission part 1641 can arch towards the direction of the actuator assembly 21 under the support of the movable valve body 163. The movable valve body 163 applies a force to the movable valve body 163 by pressing against the arched transmission part 1641, thereby pushing the movable valve body 163 to move away from the position of the third opening 1624.

[0033] The actuator assembly 21 can include a driving member 211 and an operating member 212. The operating member 212 includes a push rod. When the driving member 211 operates, the push rod presses against the transmission part 1641 from the side of the isolation member 164 facing away from the third opening 1624, causing it to deform. The side of the transmission part 1641 facing the third opening 1624 presses against the movable valve body 163. Thus, when the transmission part 1641 deforms, it pushes the movable valve body 163 to move, enabling the movable valve body 163 that seals the third opening 1624 to leave the third opening 1624.

[0034] Optionally, the area of the isolation member 164 outside the area corresponding to the third opening 1624 can bulge to form a protruding end 1642, and a diversion hole 1643 is formed in the protruding end 1642. The fluid inlet 112 of the fluid passage 11 is docked with the diversion hole 1643.

[0035] Further, a first groove 1626 is formed on one side of the third opening 1624 of the docking body 162. The third opening 1624 is located at the bottom of the first groove 1626. The docking assembly 16 further includes a gland 161. The shape of the gland 161 is adapted to the first groove 1626. The gland 161 is pressed on the first groove 1626, and the edge of the isolation member 164 is pressed against the bottom of the first groove 1626.

[0036] Optionally, a second groove 1627 communicating the third opening 1624 and the diversion hole 1643 can be opened at the bottom of the first groove 1626. The isolation member 164 covers and seals the second groove 1627, thereby forming a partial fluid passage between the docking body 162 and the isolation member 164 corresponding to the second groove 1627 to divert the fluid passing through the third opening 1624 into the diversion hole 1643.

[0037] The gland 161 has a first through groove 1611 and a second through groove 1612 on the side facing the third opening 1624. The first through groove 1611 avoids the part of the isolation member 164 corresponding to the third opening 1624, and the second through groove 1612 avoids the protruding end 1642. An external force acts on the side of the gland 161 facing away from the third opening 1624 through the first through groove 1611 to operate the movable valve body 163.

[0038] Optionally, a boss 16411 may also be provided at the position of the transmission part 1641 corresponding to the third opening 1624. The boss 16411 protrudes away from the movable valve body 163 through the first through groove 1611 so as to abut against the actuator assembly 21 to achieve transmission cooperation.

[0039] Optionally, the second through groove 1612 is used to avoid the protruding end 1642 provided with the diversion hole 1643, so that the fluid inlet 112 can be docked with the diversion hole 1643 through the second through groove 1612.

[0040] Further, the protruding end 1642 may be a flexible component, so as to form an interference fit between the protruding end 1642 and the fluid inlet 112 to complete the docking of the fluid inlet 112 of the fluid passage 11 and the third opening 1624.

[0041] Refer to Figure 9 , Figure 9 FIG. is a schematic cross-sectional structure diagram of a reagent kit in an embodiment of the medical detection device of the present application. The reagent kit 1 may further include a diversion member 13. At least part of the fluid passage 11 is opened in the diversion member 13, at least one fluid inlet 112 is provided at one end of the diversion member 13, and the other end of the diversion member 13 serves as a fluid outlet 111. Or the other end of the diversion member 13 is docked with one end of the remaining part of the fluid passage 11, and the other end of the remaining part of the fluid passage 11 serves as a fluid outlet 111.

[0042] For the flexible protruding end 1642, a second installation space 1614 communicating with the second through groove 1612 may be provided on the side of the gland 161 facing the spacer 164. The radial dimension of the second installation space 1614 is slightly larger than the radial dimension of the protruding end 1642 to limit the protruding end 1642 while accommodating it, and prevent the protruding end 1642 from deforming under the extrusion of the diversion member 13, resulting in poor sealing of the fluid passage 11.

[0043] Optionally, the opening of the first through groove 1611 facing the actuator assembly 21 may be provided with a guiding inclined surface to facilitate the smooth docking of the actuator assembly 21 and the first through groove 1611. The opening of the second through groove 1612 and / or the diversion hole 1643 facing the fluid inlet 112 may also be provided with a guiding inclined surface to facilitate the smooth docking of the diversion member 13 and the diversion hole 1643.

[0044] Specifically, the diversion member 13 may further include a diversion end 131. The reagent kit 1 may be provided with a through groove 12, and the diversion end 131 is docked with the remaining part of the fluid passage 11 in the reagent kit 1 through the through groove 12 to communicate the liquid bag / outer space and the fluid passage 11.

[0045] Optionally, an installation groove 1613 may be provided on the side of the docking component 16 facing away from the third opening 1624. The flow guiding member 13 is embedded in the installation groove 1613. One end of the flow guiding member 13 provided with the fluid inlet 112 is docked with the flow guiding hole 1643 through the second through groove 1612.

[0046] Specifically, the second through groove 1612 may be opened at the bottom of the installation groove 1613. One end of the flow guiding member 13 provided with the flow guiding inlet is directly docked with the flow guiding hole 1643 from the installation groove 1613 through the second through groove 1612.

[0047] Optionally, the movable valve body 163 may include a moving rod 1631 and a sealing member 1633. Among them, the sealing member 1633 is disposed at one end of the moving rod 1631 close to the third opening 1624 and can move in the cavity 1622 along the axial direction of the moving rod 1631. The radial dimension of the surface of the sealing member 1633 facing the third opening 1624 is greater than the radial dimension of the third opening 1624, so as to close the fluid passage 11 when the sealing member 1633 moves to block the third opening 1624.

[0048] Optionally, a convex ring 1632 is provided on the circumferential side of the moving rod 1631. The sealing member 1633 may be a flexible component and is sleeved on the outer periphery of the convex ring 1632. When the movable valve body 163 moves to block the third opening 1624, the flexible sealing member 1633 deforms, thereby forming a tight block for the third opening 1624.

[0049] Optionally, a spring 165 may be sleeved on the moving rod 1631. One end of the cavity 1622 away from the third opening 1624 has a first abutting portion 16221, and one surface of the sealing member 1633 close to the spring 165 has a second abutting portion 16331. The spring 165 abuts between the first abutting portion 16221 and the second abutting portion 16331, so that the moving rod 1631 moves towards the third opening 1624 to block the third opening 1624 by the sealing member 1633 when no external force acts.

[0050] Specifically, referring to Figure 6 , the spring 165 may be sleeved on the side of the moving rod 1631 away from the third opening 1624. The first abutting portion 16221 is disposed on the side of the encapsulation cover 1628 facing the inside of the cavity 1622, and the second abutting portion 16331 is disposed on the side of the sealing member 1633 opposite to the encapsulation cover 1628. The spring 165 abuts between the encapsulation cover 1628 and the sealing member 1633, so that the acting direction of the elastic force is parallel to the axial direction of the moving rod 1631, and further the stability of the movable valve body 163 for controlling the opening or closing of the fluid passage 11 can be improved.

[0051] Referring to Figure 8 , Figure 8It is a schematic structural diagram of the docking component of the present application. The docking main body 162 may include a packaging cover 1628, and the packaging cover 1628 covers the side of the docking main body 162 where the second opening 1623 is provided. A third through groove 16282 is formed at the position of the packaging cover 1628 corresponding to the moving rod 1631. The radial dimension of the third through groove 16282 is smaller than the radial dimension of the convex ring 1632, and the fluid enters the cavity 1622 through the third through groove 16282. When the docking component 16 is produced and assembled, the movable valve body 163 can be placed into the cavity 1622 through the second opening 1623, and the packaging cover 1628 is used to limit the movable valve body 163.

[0052] Among them, the moving rod 1631 can be inserted into the third through groove 16282. The third through groove 16282 can be a square hole. The part of the moving rod 1631 inserted into the third through groove 16282 is a cylindrical rod. The side length of the square hole is the same as the radial dimension of the cylindrical rod, so that while the moving rod 1631 is limited in the third through groove 16282, the fluid can pass through smoothly.

[0053] Optionally, the packaging cover 1628 includes a third limiting portion 16281, and a fourth limiting portion 1629 is provided at the docking main body 162 near the second opening 1623. The third limiting portion 16281 and the fourth limiting portion 1629 are snap-fitted to fix the packaging cover 1628 on the docking main body 162.

[0054] Furthermore, when the sealing member 1633 blocks the third opening 1624, one end of the moving rod 1631 facing the third opening 1624 can pass through the third opening 1624, pushing the transmission portion 1641 away from the third opening 1624, and thus forming a movable space between the transmission portion 1641 and the third opening 1624. When an external force acts on the transmission portion 1641, the transmission portion 1641 moves towards the third opening 1624 to compress this movable space, driving the moving rod 1631 abutted against the transmission portion 1641 to move, and further causing the sealing member 1633 to leave the position blocking the third opening 1624, connecting the liquid bag / outer space and the fluid passage 11.

[0055] Optionally, when the sealing member 1633 blocks the third opening 1624, the moving rod 1631 can be at least partially inserted into the second opening 1623 and / or the third opening 1624. The inner diameter of the second opening 1623 and / or the third opening 1624 is slightly larger than the outer diameter of the moving rod 1631 to limit the moving rod 1631 to fix its axial direction.

[0056] Among them, a drainage groove 1625 can be formed on the inner wall of the second opening 1623 and / or the third opening 1624. The drainage groove 1625 is used to connect the fluid inlet 112 and the liquid bag / outer space when the sealing member 1633 leaves the third opening 1624.

[0057] Refer to Figure 10 , Figure 10 which is a schematic diagram of the fluid passage structure of an embodiment of the medical detection device of the present application. The present application also provides a medical detection device, including a device main body 2, an execution component 21, and a reagent kit 1.

[0058] The execution component 21 can be installed on the device main body 2 and is used to selectively drive the movable valve body 163 to open or close.

A fluid passage 11 is provided inside the reagent kit 1, and the reagent in the liquid bag or the gas in the external space can flow into the test card 3 through the fluid passage 11. Specifically, the fluid passage 11 has a fluid outlet 111 and at least one fluid inlet 112. The fluid outlet 111 is used to connect to the test card 3, and the fluid inlet 112 is used to connect to the liquid bag and / or the external space. A movable valve body 163 can be provided between the fluid inlet 112 and the fluid outlet 111 of the fluid passage 11, or at a position where the liquid bag / external space is adjacent to the fluid inlet 112, so as to control the connection or disconnection of the fluid passage 11 by using the movable valve body 163.

[0061] Optionally, the reagent kit 1 can specifically further include a box body 15 and a docking component 16. A first installation space 151 is formed inside the box body 15, and a first opening 152 is provided on one side of the first installation space 151 close to the execution component 21.

[0062] Further, one of a slide rail 1621 and a slider 153 can be provided on the edge of the first opening 152, and the other of the slide rail 1621 and the slider 153 can be provided on the docking main body 162. The slide rail 1621 and the slider 153 are in sliding fit with each other to install the docking main body 162 on the first opening 152.

[0063] Such as Figure 2 , 3As shown in FIGS. 4, the first opening 152 can be an open opening with one side open. The number of docking components 16 is at least two, and all docking bodies 162 are stacked in the first opening 152 along the direction of the slide rail 1621 through the open side of the first opening 152. Among them, the docking body 162 closest to the open side of the first opening 152 can be used to communicate with the external space.

[0064] The kit 1 may further include a fixing member 14, and the fixing member 14 seals the open side of the first opening 152 and limits all the docking bodies 162 installed in the first opening 152 within the first opening 152.

[0065] Optionally, a test card installation position 155 may be further provided at a position of the box body 15 close to the detection component 22 in the device main body 2, and the fluid outlet 111 of the fluid passage 11 may be arranged in the test card installation position 155 to realize the docking of the fluid passage 11 and the test card 3.

[0066] The docking component 16 may include a docking body 162 and a movable valve body 163. The docking body 162 has a cavity 1622, a second opening 1623 and a third opening 1624 communicating with the cavity 1622. The second opening 1623 is used for docking with the liquid bag / external space, and the third opening 1624 is used for connecting the test card 3 through the fluid passage 11 in the kit 1.
