Description

A medical testing device Technical Field

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

[0002] When testing samples using medical testing equipment, it's often necessary to extend the sampling assembly of the medical testing equipment through a window inside the device to facilitate the introduction of the sample into the device. To protect the cleanliness of the sampling assembly, the medical testing equipment typically includes a door that shields this window. Before extending the sampling assembly from the device, the door on the device housing must be opened, and the sampling assembly must be separated from the docking assembly, as the sampling assembly is located within the device and docks with the docking assembly to connect to the detection system within the device.

[0003] Currently, there are two common methods. One is to perform these two steps separately, for example, manually opening the door first and then manually separating the sampling assembly from the docking assembly, which makes it difficult to achieve synchronous control of the two. The other is to use a lead screw electrode to slowly control the separation of the sampling assembly and the docking assembly while opening the door. However, this second method uses a lead screw electrode for control, and the lead screw rotates slowly, resulting in a long overall time, affecting the convenience and usability of medical testing equipment.

[0004] Summary of the Invention

[0005] The technical problem to be solved by the present application is how to provide a medical detection device that can efficiently and synchronously control the door and the docking assembly, thereby improving the usability of the medical detection device.

[0006] The present application provides a medical detection device, including a shell, a linkage assembly, a lever assembly and a driving member. The shell is provided with a window and a door capable of covering the window. The linkage assembly is used to link the door and a docking assembly of a test kit, so that when the sampling assembly and the docking assembly of the test kit are docked, the door is driven to cover the window, and when the sampling assembly and the docking assembly are separated, the door is driven to open the window. One end of the lever assembly is connected to the linkage assembly, and the other end drives the connected driving member.

[0007] Different from the existing technology, the present application discloses a medical testing device that can use a driving member to drive one end of a lever assembly, so that the linkage assembly at the other end of the lever assembly can synchronously control the door and the docking assembly. Under the action of the lever assembly, the sampling assembly and the docking assembly can be efficiently and accurately controlled to separate when the door is opened, effectively improving the efficiency and usability of the medical testing equipment during testing.

[0021] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] The terms "first," "second," and the like in this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "comprising," and "provided with," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] With the advancement of analytical technology, medical testing equipment can now utilize a sampling assembly to obtain samples and / or other reagents. The sampling assembly can then be docked with a docking assembly of the medical testing equipment, allowing the sample in the sampling assembly to be transferred to the testing assembly of the medical testing equipment through a pipeline in the docking assembly. To protect the cleanliness of the sampling assembly, medical testing equipment typically houses the sampling assembly and docking assembly inside the device. The sampling assembly is docked with the docking assembly by default, and is disconnected from the docking assembly when needed, allowing the sample to be extended through a window in the device.

[0025] The window is generally provided with a door for shielding, thereby preventing dust and dirt from falling through the window and contaminating the internal structure of the medical testing device. Before extending the sampling assembly from the interior of the medical testing device, the door provided on the device housing must be opened, and the sampling assembly must also be separated from the docking assembly.

[0026] In several common medical testing devices in the past, these two steps were either all manually controlled and performed in steps by the user, such as the user manually opening the door and then manually separating the sampling component from the docking component; or the user manually controlled one step while the other step was performed mechanically; in some cases, the two steps were slowly controlled by a lead screw electrode, but due to the structural limitations of the lead screw motor, these two steps would be performed extremely slowly, thereby slowing down the speed of the entire testing process and damaging the detection efficiency and usability of the medical testing equipment.

[0027] How to provide a medical testing device that can efficiently and synchronously control the door and docking components, thereby improving the usability of the medical testing device, is a major problem that the medical testing device provided in this application aims to solve.

[0028] As shown in Figures 1 to 3, Figure 1 is a schematic diagram of the assembly of an embodiment of the medical detection device of the present application. Figure 2 is a schematic diagram of the structure of the housing, linkage assembly, lever assembly, and driver in Figure 1. Figure 3 is a schematic diagram of the structure of the linkage assembly, lever assembly, and driver in Figure 1.

[0029] The present application provides a medical detection device 9, comprising a housing 1, a linkage assembly 2, a lever assembly 5, and a drive member 6. The housing 1 is provided with a window 11 and a door 12 capable of covering the window 11. The sampling assembly 93 of the medical detection device 9 is arranged inside the housing 1, and when it is necessary to introduce a sample or other reagent into the medical detection device 9, the sampling assembly 93 can be separated from the docking assembly 92 and extended through the window 11 for sampling. The linkage assembly 2 is used to link the door 12 and the docking assembly 92 of the reagent box 91, so that when the sampling assembly 93 of the reagent box 91 is docked with the docking assembly 92, the door 12 is driven to cover the window 11, and when the sampling assembly 93 and the docking assembly 92 are separated, the door 12 is driven to open the window 11. One end of the lever assembly 5 is connected to the linkage assembly 2, and the other end is driven to connect to the drive member 6, so that the door 12 and the docking assembly 92 are synchronously controlled under the drive of the drive member 6.

[0030] The medical detection equipment 9 provided in this embodiment can utilize the driving member 6 to drive one end of the lever assembly 5, so that the linkage assembly 2 at the other end of the lever assembly 5 can synchronously control the door 12 and the docking assembly 92, and can utilize the principle of the lever 51 to efficiently and accurately control the sampling assembly 93 and the docking assembly 92 to separate when the door 12 is opened, thereby effectively improving the efficiency and usability of the medical detection equipment 9 during detection.

[0031] Optionally, the medical testing device 9 can use a sample test card to test the sample. Therefore, the housing 1 is further provided with a test card installation port 18 and a card door 1912 capable of covering the test card installation port 18 .

[0032] Referring to Figures 3 and 4, Figure 4 is a schematic diagram of the structure of the lever assembly in Figure 1. The lever assembly 5 may include a lever 51 and a lever bracket 15. One end of the lever 51 is connected to the linkage assembly 2, and the other end is connected to the driving member 6. The lever bracket 15 includes two side plates 521, and a clearance groove 529 is formed between the two side plates 521 for accommodating the lever 51. The two side plates 521 are fixed to the housing 1. The lever 51 passes through the clearance groove 529 and is rotatably connected to the two side plates 521, so that the lever 51 can be limited to a certain position by the lever bracket 15.

[0033] Optionally, the lever 51 can extend the shaft 511 to the two side plates 521, and two mounting grooves 527 are symmetrically provided on the two same-direction side edges 526 of the two side plates 521. The two same-direction side edges 526 of the two side plates 521 each have protruding mounting ears 528 at both ends, so that the two side plates 521 can be installed on the shell 1 through the mounting ears 528, so as to relatively fix the lever assembly 5 on the shell 1, and enable the lever 51 to use the shaft 511 as a fulcrum to realize the function of the lever 51.

[0034] Optionally, the lever assembly 5 may further include a lever pressing cover 53 fixed to the lever bracket 15, and the edge of the lever pressing cover 53 extends two limiting protrusions 533 at least toward the two side plates 521. The lever pressing cover 53 is embedded between the mounting ears 528 of the two same-direction side edges 526 of the two side plates 521, and the two limiting protrusions 533 are used to limit the shaft body 511 between the two mounting grooves 527 and the two limiting protrusions 533, so that the lever 51 is pressed into the lever bracket 15 by using the lever pressing cover 53 to fix the fulcrum of the lever 51.

[0035] Optionally, the lever pressing cover 53 may further include a top plate 531 and two fixing plates 532 extending from opposite sides of the top plate 531 toward the side plates 521. Two limiting protrusions 533 extend from the two fixing plates 532, respectively. Each fixing plate 532 extends away from the lever 51, forming at least one first mounting portion 534. Each first mounting portion 534 defines a first mounting hole 535. Each side plate 521 also extends away from the lever 51, forming at least one second mounting portion 522. Each second mounting portion 522 defines a second mounting hole 523. The first mounting holes 535 correspond to the second mounting holes 523. Each side plate 521 also extends away from the lever 51, forming at least one third mounting portion 524. Each third mounting portion 524 defines a third mounting hole 525. The housing 1 may further include a frame plate 13 and a fastener 14. The frame plate 13 defines a fourth mounting hole corresponding to the third mounting hole 525. The fastener 14 is inserted into the first mounting hole 535 and the second mounting hole 523 to secure the lever cover 53 to the lever bracket 15. The fastener 14 is also inserted into the third mounting hole 525 and the fourth mounting hole to relatively secure the entire lever assembly 5 and to secure the entire lever assembly 5 to the frame plate 13.

[0036] Optionally, the linkage assembly 2 may include a first linkage member 21, which is located at one end of the lever 51. The first linkage member 21 can be transmission-connected to the docking assembly 92 when the test kit 91 is assembled with the shell 1, thereby driving the docking assembly 92 and the door 12 to move under the driving action of the driving member 6.

[0037] Further, referring to Figure 5, which is an exploded view of a portion of the linkage assembly and the lever assembly in Figure 1, the first linkage member 21 may include a first docking portion 211 and a first linkage portion 213. The first docking portion 211 is configured to engage with the docking assembly 92, and the first linkage portion 213 is configured to engage with the door 12, thereby enabling the lever assembly 5 to synchronously control the movement of the door 12 and the docking assembly 92.

[0038] Among them, the linkage component 2 also includes a first linkage component 3 installed on the shell 1, one end of the first linkage component 3 is connected to the first linkage part 213, and the other end is connected to the door 12 to drive the door 12 to move under the force transmitted from the first linkage part 213.

[0039] The first linkage assembly 3 may further include a second linkage member 31 and a transmission assembly 320 that transmits and connects the door 12 and the second linkage member 31 . The second linkage member 31 is docked with the first linkage portion 213 to move relative to the housing 1 under the action of the first linkage portion 213 .

[0040] The moving direction of the second linkage member 31 is perpendicular to the opening or closing direction of the door 12 .

[0041] Optionally, the transmission assembly 320 includes a fifth transmission member 3201 transmission-connected to the second linkage member 31, a sixth transmission member 3202 transmission-connected to the fifth transmission member 3201, a seventh transmission member 3203 transmission-connected to the sixth transmission member 3202, and an eighth transmission member 3204 rotationally connected to the seventh transmission member 3203, wherein the eighth transmission member 3204 is assembled with the door 12;

[0042] The movement of the second linkage member 31 drives the fifth transmission member 3201 to rotate, and the sixth transmission member 3202 rotates synchronously with the fifth transmission member 3201. The rotation of the sixth transmission member 3202 drives the movement of the seventh transmission member 3203, and the movement of the seventh transmission member 3203 drives the rotation of the eighth transmission member 3204. The door 12 rotates synchronously with the eighth transmission member 3204. The movement direction of the third transmission member 3203 is perpendicular to the movement direction of the second linkage member 31. As shown in Figures 5 to 7, Figure 6 is a schematic structural diagram of the first linkage assembly of the present application. Figure 7 is another schematic structural diagram of the first linkage assembly of the present application.

[0043] The second linkage member 31 may include a groove body 311, in which a slider 312 is embedded. The first linkage part 213 includes a hook 214 arranged parallel to the second linkage member 31, and the hook 214 is hung on the slider 312, so that when the lever 51 drives the first linkage part 213 to swing away from the door 12, it drives the second linkage member 31 to slide away from the door 12.

[0044] Optionally, a first elastic member 313 is provided on the side of the groove body 311 close to the lever 51, and the first elastic member 313 is pressed between the side of the groove body 311 close to the lever 51 and the slider 312, so that when the hook 214 drives the second linkage member 31 to slide away from the door 12, part of the impact force caused by the excessive movement is offset, so as to avoid damage to the hook 214 and / or the second linkage member 31, thereby improving the service life of the medical detection equipment 9.

[0045] Optionally, the linkage assembly 2 may further include a base 314 fixed to the housing 1, and the base 314 is used to mount the door 12, the second linkage member 31, and the transmission assembly 320 to the housing 1. One of the second linkage member 31 and the base 314 may further include at least one first limiting post 315, and the other may further include at least one first limiting portion 316, with the at least one first limiting post 315 being disposed in a one-to-one correspondence with the at least one first limiting portion 316.

[0046] When the second linkage member 31 moves relative to the base 314 , the first limiting column 315 can move relative to the housing 1 .

[0047] Optionally, at least one end of each limiting post is further provided with a second limiting portion 317, and a second elastic member 318 is provided between the second limiting portion 317 and the corresponding first limiting portion 316. When the second linkage member 31 moves relative to the base 314 under the action of the first linkage member 213, the second elastic member 318 presses against the first limiting portion 316 and the second limiting portion 317 to change shape and generate elastic force, thereby preventing damage to the second linkage member 31 and extending the service life of the medical detection device 9. When the action of the first linkage member 213 is cancelled, the second elastic member 318 can restore its shape, thereby causing the second linkage member 31 to return to its original position.

[0048] Optionally, the linkage assembly 2 also includes a first pressure cover 319, which is arranged on the side of the second linkage part 31 away from the seat body 314 to separate the second linkage part 31 from other structures in the medical device, thereby preventing other irrelevant structures of the medical detection equipment 9 from affecting the operation of the second linkage part 31.

[0049] Optionally, the seat body 314 may be further provided with symmetrical fixing protrusions 314 a for fixing the first pressure cover 319 .

[0050] 5 and 8 , which is a cross-sectional view of the second linkage assembly of the present invention. The linkage assembly 2 may further include a second linkage assembly 4 , one end of which is connected to the docking assembly 92 and the other end of which is connected to the first docking portion 211 .

[0051] Furthermore, the second linkage assembly 4 includes a third linkage member 41, a fourth linkage member 42, and a fifth linkage member 43. The fourth linkage member 42 is provided with a first installation space 421 arranged in a cylindrical shape. The fourth linkage member 42 is provided with a first opening 422 at one end thereof, which is connected to the first installation space 421, and a second opening 423 at the other end thereof, which is connected to the first installation space 421. One end of the third linkage member 41 is connected to the first docking portion 211, and the other end is at least partially inserted into the first installation space 421 through the first opening 422, and the third linkage member 41 and the fourth linkage member 42 are relatively fixed. One end of the fifth linkage member 43 is at least partially inserted into the first installation space 421 through the second opening 423, and the other end is connected to the docking assembly 92, and the fifth connecting member is movably connected to the fourth linkage member 42.

[0052] In this embodiment, when the third linkage member 41 moves relative to the sampling assembly 93 under the action of the first docking portion 211 , the third linkage member 41 drives the fourth linkage member 42 and the fifth linkage member 43 to move, thereby driving the docking assembly 92 to separate from the sampling assembly 93 .

[0053] Optionally, the third linkage member 41 is provided with one of the first limiting hole 411 and the first limiting rod 211 at one end close to the lever 51, and the first docking portion 211 is provided with the other of the first limiting hole 411 and the first limiting rod 211, and the first limiting rod 211 is passed through the first limiting hole 411, thereby connecting the third linkage member 41 and the first linkage member 21.

[0054] Among them, the size of the first limiting hole 411 in the horizontal direction is greater than or equal to the sum of the radial size of the first limiting rod 211 in this direction and the displacement of the first limiting rod 211 in this direction during the swinging of the lever 51, thereby reserving sufficient buffer space for the displacement of the lever 51 in the horizontal direction when it swings, so that the third linkage 41 under the control of the lever 51 can not be displaced in the horizontal direction.

[0055] Optionally, the housing 1 includes a bracket 15 , the bracket 15 includes a plurality of frame plates 13 , and the plurality of frame plates 13 cooperate to form a cavity for assembling the reagent kit 91 , and the second linkage assembly 4 is assembled on the frame plate 13 near the lever assembly 5 .

[0056] Optionally, the second linkage component 4 can also include a first limit member 44, which is fixed to the side of the frame plate 13 close to the docking component 92, and the frame plate 13 is provided with a third opening 17 corresponding to the first limit member 44, and the first limit member 44 is provided with a second installation space 441, and the first limit member 44 is provided with a fourth opening 442 connected to the second installation space 441 at a position corresponding to the third opening 17, and a fifth opening 443 connected to the second installation space 441 is provided on the side close to the docking component 92.

[0057] The third linkage member 41, the fourth linkage member 42, and the fifth linkage member 43 are disposed in the second installation space 441 through the fourth opening 442, and the fifth linkage assembly 2 is docked with the docking assembly 92 through the fifth opening 443. The fourth connecting assembly further includes a third limiting portion 424. When the third limiting portion 424 abuts against the inner wall of the second installation space 441 near the fifth opening 443, the end of the lever 51 connected to the first docking portion 211 swings to its limit toward the docking assembly 92, and the docking assembly 92 docks with the sampling assembly 93.

[0058] Optionally, the second linkage assembly 4 may further include a second limiting member 45, which is fixed relative to the first limiting member 44 and disposed on a side of the frame plate 13 proximate to the first docking portion 211. The second limiting member 45 defines a third installation space 451, and further defines a sixth opening 452 at a position corresponding to the fourth opening 442, connecting the second installation space 441 and the third installation space 451, and a seventh opening 453 on a side proximate to the first docking portion 211, connecting the third installation space 451. The third linkage member 41 further includes a fourth limiting portion 412, and the first docking portion 211 is fixed relative to the third linkage member 41 via the seventh opening 453.

[0059] When the fourth limiting portion 412 abuts against the inner wall of the third installation space 451 away from the sixth opening 452 , the end of the lever 51 connected to the first docking portion 211 swings to the limit in the direction away from the docking assembly 92 , thereby separating the docking assembly 92 from the sampling assembly 93 .

[0060] Referring to Figures 2, 3, 9, and 10, Figure 9 is a schematic diagram of the structure of the driving member in Figure 1. Figure 10 is another schematic diagram of the structure of the driving member in Figure 9. As shown in the figure, the driving member 6 includes a third linkage assembly 7 and a motor 8. The motor 8 is connected to one end of the third linkage assembly 7, and the third linkage assembly 7 is connected to the other end of the lever assembly 5.

[0061] Optionally, the third linkage assembly 7 includes a first transmission member 71 connected to the motor 8, a second transmission member 72 connected to the first transmission member 71, and a third transmission member 73 connected to the second transmission member 72. The third transmission member 73 is assembled with the lever assembly 5, thereby driving the lever assembly 5 to swing along the moving direction of the third transmission member 73.

[0062] Among them, under the action of the motor 8, the first transmission member 71 rotates, and the second transmission member 72 rotates synchronously with the first transmission member 71. The rotation of the second transmission member 72 drives the third transmission member 73 to move, thereby driving the lever assembly 5 to move. The direction of movement of the third transmission member 73 is perpendicular to the axial direction of rotation of the first transmission member 71 and the second transmission member 72.

[0063] Optionally, the second transmission member 72 includes a linkage wheel 721 , a transmission wheel 722 and a rotating shaft 725 connecting the linkage wheel 721 and the first transmission member 71 , and the transmission wheel 722 is transmission connected to the third transmission member 73 .

[0064] Optionally, the transmission wheel 722 includes a connecting portion 723 and a transmission portion 724. A rotation axis 725 is inserted into the connecting portion 723, and the transmission portion 724 extends from the connecting portion 723 in a direction away from the rotation axis 725. The third transmission member 73 defines a rotation hole 731, and the transmission wheel 722 is at least partially disposed in the rotation hole 731. The radial dimension of the rotation hole 731 in the direction of movement of the third transmission member 73 is smaller than the radial dimension in a direction perpendicular to the movement of the third transmission member 73. When the transmission wheel 722 rotates until the connecting portion 723 abuts the inner wall of the rotation hole 731 on the side closer to the lever assembly 5, the transmission portion 724 abuts the inner wall of the rotation hole 731 on the side away from the lever assembly 5.

[0065] When the transmission part 724 rotates around the rotation axis 725 toward the direction approaching the lever assembly 5 , the third transmission member 73 drives the lever assembly 5 to move toward the direction away from the motor 8 synchronously.

[0066] Alternatively, referring to Figure 12, Figure 12 is a schematic diagram of the structure of the drive member in Figure 1. The drive member 6 further includes a motor bracket 82 and a second gland 83. The motor bracket 82 is fixed to the housing 1, through which the motor 8 and the third linkage assembly 7 are assembled to the housing 1. The second gland 83 is fixed to the motor bracket 82 and covers at least the side of the motor 8 and the third transmission member 73 facing away from the motor bracket 82. The second gland 83 defines a first through-hole 84 at the driving end 81 of the motor 8. The second gland 83 defines a second through-hole 85 at the transmission wheel 722, corresponding to the transmission wheel 724. The first transmission member 71, mounted on the second gland 83, is drivingly connected to the driving end 81 extending through the first through-hole 84, thereby driving the linkage wheel 721 to rotate. The transmission wheel 722 is drivingly connected to the rotation hole 731 of the third transmission member 73 through the second through-hole 85, and the rotation shaft 725 can be assembled to the motor bracket 82 through the second through-hole 85.

[0067] Optionally, the rotating shaft 725 can pass through the side of the connecting portion 723 away from the linkage wheel 721, so as to be plugged and fixed to the fixing hole 87 provided on the motor bracket 82, thereby better limiting the conducting wheel 722 and the entire second transmission member 72.

[0068] Optionally, the motor bracket 82 may be further provided with a fixing groove for accommodating the motor 8 , thereby achieving better positioning of the electrode 8 .

[0069] Optionally, the motor bracket 82 and the second pressure cover 83 are relatively fixed by at least one fixing portion 89 .
