Description

Technical Field

[0001] The disclosed embodiments of this application relate to the field of sample analysis technology, and more specifically, to detection components and medical testing equipment for medical testing devices. Background Technology

[0002] During sample testing, the testing component needs to be inserted into the slot of the medical testing equipment so that the testing electrodes on the testing component make contact with the contact electrodes in the slot of the medical testing equipment. This allows the testing circuit in the medical testing equipment to receive the signal transmitted from the testing component, thereby realizing sample testing.

[0003] The detection component is generally a box-shaped hexahedron, with detection electrodes disposed on one surface of the component. Therefore, when the detection component is inserted into the slot of the medical testing device, in order to avoid the edge of the slot opening coming into contact with the detection electrodes on the surface of the component and causing damage to the electrodes, the slot opening needs to be larger than the cross-section of the detection component by a certain size. Furthermore, the detection electrodes protruding from the surface of the component also increase the thickness of the detection component. Summary of the Invention

[0005] This application provides a detection component for a medical testing device, comprising: a housing and a detection electrode. The housing has a top surface, a bottom surface, at least one side surface, an inlet, and an outlet. The at least one side surface is connected to the top surface and the bottom surface, respectively. A cavity is provided inside the housing. The inlet and outlet are respectively connected to the cavity. A groove is formed in the region of the top surface adjacent to the at least one side surface. The detection electrode is located in the groove, and the portion of the groove on the top surface has an opening on the at least one side surface.

[0006] This application provides another medical testing device, including an instrument body, the instrument body including a slot and a contact electrode, the slot being used to insert a testing component, and when the testing component is inserted into the medical testing device, the contact electrode is in contact with the testing electrode of the testing component.

[0007] The beneficial effects of this application are as follows: the detection electrode is disposed in the groove formed by the top surface and at least one side surface of the detection component housing, the plane on which the detection electrode is located is parallel to the top surface, and the detection electrode is not located on one surface of the detection component. Therefore, during the process of inserting the detection component into the slot, the edge of the slot opening will not come into contact with the detection electrode of the detection component, thereby reducing the size of the slot opening, reducing the volume of the medical detection device, and also reducing the thickness of the detection component.

[0008] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this application. Attached Figure Description

[0016] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, "many" in this application means two or more. Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0018] During sample testing, the testing component needs to be inserted into the slot of the medical testing equipment so that the testing electrodes on the testing component make contact with the contact electrodes in the slot of the medical testing equipment. This allows the testing circuit in the medical testing equipment to receive the signal transmitted from the testing component, thereby realizing sample testing.

[0019] The detection component is generally a box-shaped hexahedron, with detection electrodes disposed on one surface. To facilitate the avoidance of the detection component by the contact electrodes on the medical device during the insertion process, a drive component for the contact electrodes is required within the medical device. This drive component retracts the contact electrodes outside the slot into the medical device before insertion and drives them back into the slot until they contact the detection electrodes on the surface of the detection component after insertion. The space within the slot on the medical detection device is not effectively utilized before insertion. Furthermore, to avoid the detection electrodes on the surface of the detection component, the slot opening needs to be larger than the cross-section of the detection component, further increasing the size of the medical detection device. Additionally, the detection electrodes protruding from the surface of the detection component also increase its thickness.

[0020] To address the aforementioned problems, this application provides the following technical solutions. To enable those skilled in the art to better understand the technical solutions of this application, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the technical solutions of this application.

[0021] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a detection component for a medical testing device according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a detection component for a medical testing device according to another embodiment of this application. Figure 3 This is a schematic diagram of the structure of a detection component for a medical testing device according to another embodiment of this application. The detection component 70 includes: a housing 7006 and a detection electrode 71. The housing 7006 has a top surface 70061, a bottom surface 70062, at least one side surface 70063, a liquid inlet 7003, and a liquid outlet 7004. The at least one side surface 70063 is connected to the top surface 70061 and the bottom surface 70062 respectively. A cavity 7006a is provided inside the housing 7006. The liquid inlet 7003 and the liquid outlet 7004 are respectively connected to the cavity 7006a. A groove 77 is formed by a recess in the area of ​​the top surface 70061 adjacent to the at least one side surface 70063. The detection electrode 71 is located in the groove 77. The portion of the groove 77 located on the top surface 70061 has an opening 78 on the at least one side surface 70063.

[0022] In this embodiment, the detection component 70 is generally rectangular in shape, including a top surface 70061, a bottom surface 70062, and four side surfaces 70063. The top and bottom sides of the four side surfaces 70063 are connected to the edges of the top surface 70061 and the bottom surface 70062, forming a cavity 7006a. An inlet 7003 and an outlet 7004 are provided on the bottom surface 70062. The inlet 7003 can deliver the reagent package in the reagent kit to the cavity 7006a, and the outlet 7004 can output the waste liquid in the cavity 7006a and transfer the waste liquid to the waste liquid bag in the reagent kit through a pipeline.

[0023] Please see Figure 2 The length direction of the top surface 70061 is the x-direction, representing the length of the detection component; the width direction of the top surface 70061 is the y-direction, representing the width of the detection component; the width direction of the side surface 70063 is the z-direction, representing the height of the detection component; the length, width, and height directions of the groove 77 correspond to the length, width, and height directions of the detection component, respectively. The top surface 70061 and one side surface 70063 are recessed to form the groove 77. The depth of the groove 77 is less than the depth of the detection component, and the width and length of the groove 77 are less than the width and length of the top surface 70061. The detection electrode 71 is located in the groove 77, and the portion of the groove 77 located on the top surface 70061 has an opening 78 on at least one side surface.

[0024] Optionally, in another embodiment, the top surface 70061 and three adjacent side surfaces 70063 are recessed together to form a groove 77. The depth of the groove 77 is less than the depth of the detection component, the length of the groove 77 is equal to the length of the top surface 70061, and the width of the groove 77 is less than the length of two opposite side surfaces 70063, making the detection component 70 stepped, and the detection electrode 71 is located in the groove 77. The portion of the groove 77 located on the top surface 70061 has an opening 78 on at least one side surface 70063.

[0025] Therefore, in this embodiment, the detection electrode is disposed within a groove formed by the top surface and at least one side surface of the detection component housing. The plane of the detection electrode is parallel to the top surface, and the detection electrode is not located on any surface of the detection component. Thus, during the insertion of the detection component into the slot, the edge of the slot opening will not contact the detection electrode of the detection component, reducing the size of the slot opening, decreasing the volume of the medical testing device, and also reducing the thickness of the detection component. Furthermore, during the insertion of the detection component into the medical testing device, the side with the groove is inserted into the slot first, so that the side with the groove abuts against the bottom of the slot. At this time, the contact electrode on the medical device can be placed in the space at the bottom of the slot. Therefore, during the insertion of the detection component into the slot, the contact electrode does not need to avoid the detection component, and the contact electrode can be placed in the space at the bottom of the slot, effectively utilizing the space within the slot before the insertion process.

[0026] In other embodiments of this application, the top surface 70061 and the bottom surface 70062 are arranged in parallel, and at least one side surface 70063 has four sides, which are connected in pairs and arranged around each other. The portion where one side surface 70063 meets the top surface 70061 is recessed to form a groove 77 and an opening 78. The width of both the groove 77 and the opening 78 is smaller than the corresponding width of the top surface 70061 and the side surface 70063. The portion of the groove 77 corresponding to the top surface 70061 has a plane 77a and a sidewall 77b. The plane 77a is parallel to the top surface 70061 and the bottom surface 70062, and the sidewall 77b is perpendicular to the plane 77a and connects the top surface 70061 and the plane 77a respectively. The detection electrode 71 is disposed on the plane 77a.

[0027] Specifically, the top surface 70061 is recessed in the direction toward the bottom surface 70062 to form a groove 77, and the groove 77 penetrates only one side of at least one side surface 70063. The cavity 7006a is isolated from the groove 77. The detection electrode 71 is housed in the groove 77 and does not extend beyond the groove 77. In addition, the plane 77a is spaced apart from the bottom surface 70062.

[0028] In this embodiment, a groove 77 is formed by recesses in the top surface 70061 and one side surface 70063. The width and length of the groove 77 are smaller than the width and length of the top surface 70061, and the depth of the groove 77 is smaller than the depth of the detection component. The length and width of the opening 78 are smaller than the length and width of the side surface 70063. The groove 77 includes a plane 77a and three side surfaces 77b, forming an opening 78. The top sides of the three side surfaces 77b are connected to the edge of the recess in the top surface 70061, and the side edges of two of the three side surfaces 77b are connected to the edge of the recess in the side surface 70063 of the housing 7006. The detection electrode 71 is located in the plane 77a of the groove 77. The length and width of the opening 78 can be less than or equal to the length and height of the groove 77, respectively. Preferably, the length and width of the opening 78 are equal to the length and height of the groove 77, respectively.

[0029] Please see Figure 4 , Figure 4This is a schematic diagram of the assembly of a detection component according to an embodiment of this application. In this figure, the housing 7006 includes: a first housing 7006b and a second housing 7006c, the surface of the first housing 7006b facing away from the second housing 7006c is the top surface 70061, and the detection component 70 includes: a circuit board 72, the circuit board 72 has a first region 72a and a second region 72b, and a detection electrode 71 is provided in the second region 72b. The second housing 7006c includes: a base plate 7006ca and at least one first side plate 7006cb surrounding the base plate 7006ca. The bottom side of the first side plate 7006cb is connected to the edge of the base plate 7006ca. A first notch 73 is provided on the side of the first side plate 7006cb away from the base plate 7006ca. The base plate 7006ca and the first side plate 7006cb form a receiving cavity 7006cc. The surface of the base plate 7006ca facing away from the first housing 7006b is the bottom surface 70062. The outer surface of the at least one first side plate 7006cb is at least one side surface 70063. The first housing 7006b cooperates with at least one first side plate 7006cb to cover the receiving cavity 7006cc. The circuit board 72 is located between the base plate 7006ca and the first housing 7006b. The first region 72a is located in the receiving cavity 7006cc, and the second region 72b is located at the groove 77 outside the receiving cavity 7006cc to form the plane 77a of the groove 77.

[0030] In this embodiment, the housing 7006 includes a first housing 7006b and a second housing 7006c. The first housing 7006b is sleeved on the second housing 7006c and covers the receiving cavity 7006cc of the second housing 7006c, forming a cavity 7006a. A circuit board 72 is disposed between the first housing 7006b and the second housing 7006c, and a detection electrode 71 is disposed in the second region 72b of the circuit board 72. The first region 72a of the circuit board 72 is located inside the cavity 7006a, and the second region 72b of the circuit board 72 is located in a groove 77 and an opening 78, so that the detection electrode 71 is exposed in the groove 77 formed by the recess of the top surface 70061 of the first housing 7006b and the first notch 73 of at least one first side plate 7006cd of the second housing 7006c. The second region 72b of the circuit board 72 forms the plane 77a of the groove 77.

[0031] In some other embodiments of this application, the first housing 7006b includes a cover plate 7006ba and at least one second side plate 7006bb surrounding the cover plate 7006ba. The top side of the second side plate 7006bb is connected to the edge of the cover plate 7006ba. The surface of the cover plate 7006ba facing away from the second housing 7006c is the top surface 70061. The cover plate 7006ba has a second notch 74 near the first notch 73. The second side plate 7006bb corresponding to the position of the second notch 74 extends in the shape of the second notch 74. The first notch 73, the second notch 74, the second side plate 7006bb corresponding to the position of the second notch 74, and the second region 72b together form a groove 77. The second side plate corresponding to the position of the second notch forms the sidewall 77b of the groove 77.

[0032] In this embodiment, the first housing 7006b includes a cover plate 7006ba and at least one second side plate 7006bb. The top side of the second side plate 7006bb is connected to the edge of the cover plate 7006ba. The cover plate 7006ba has a second notch 74, and the shape of the second side plate 7006bb corresponds to the shape of the second notch 74. That is, the edge of the shape of the second region 72b is connected to the edge of the shape of the second side plate 7006bb. The second side plate 7006bb at the position of the second notch 74 forms the sidewall 77b of the groove 77. The second notch 74 is adjacent to the first notch 73 of at least one first side plate 7006cb. Therefore, the first notch 73, the second notch 74, the second side plate 7006bb corresponding to the position of the second notch 74, and the second region 72b together form the groove 77.

[0033] In other embodiments of this application, the housing 7006 includes a third housing 75, which includes a mounting plate 75a and at least one third side plate 75b surrounding the mounting plate 75a. The bottom side of the third side plate 75b is connected to the edge of the mounting plate 75a. The mounting plate 75a and the at least one third side plate 75b are both disposed within the receiving cavity 7006cc of the second housing 7006c. The top side of the at least one third side plate 75b is connected to the top side of the at least one first side plate 7006cb. The circuit board 72 is placed on the mounting plate 75a and is located between the mounting plate 75a and the first housing 7006b. The third side plate 75b corresponding to the position of the first notch 73 has a third notch 76, the shape of which is consistent with the shape of the first notch 73.

[0034] In this embodiment, the third housing 75 is disposed within the receiving cavity 7006cc of the second housing 7006c, and the top side of at least one third side plate 75b of the third housing 75 is connected to the top edge of the second side plate 7006bb of the second housing 7006c. The bottom side of the third side plate 75b is connected to the edge of the mounting plate 75a. The mounting plate 75a is parallel to the bottom plate 7006ca and the cover plate 7006ba, and a circuit board 72 is placed on the mounting plate 75a. One of the third side plates 75b has a third notch 76, the shape of which is the same as that of the first notch 73, and the height of the third side plate 75b is slightly greater than the depth of the first notch 73. When the circuit board 72 is placed on the mounting plate 75a, the horizontal plane 77a on which the upper surface of the circuit board 72 is located is equal to or slightly higher than the horizontal plane 77a of the recess of the first notch 73. The second housing 7006c and the third housing 75 can be integrally formed or detachably connected.

[0035] Please see Figure 5 , Figure 5 This is a top view of the second housing of a detection assembly according to an embodiment of this application. In this figure, the mounting plate 75a has a protruding rib 75c near the edge of the third side plate 75b. The protruding rib 75c surrounds the periphery of the circuit board 72 to limit the circuit board 72.

[0036] In this embodiment, the shape of the rib 75c is consistent with the shape of the circuit board 72 and surrounds the periphery of the circuit board 72 to limit the circuit board 72 and prevent the circuit board 72 from being displaced within the receiving cavity 7006cc. This ensures that the detection electrode 71 on the second region 72b of the circuit board 72 is always in a fixed position, and avoids misalignment between the contact electrode and the detection electrode 71 during the contact process after the detection component 70 is inserted into the slot.

[0037] Optionally, when the circuit board 72 is placed on the mounting plate 75a, the horizontal plane 77a on which the upper surface of the circuit board 72 is located is equal to or slightly higher than the height of the protruding rib 75c.

[0038] In some other embodiments of this application, the detection component 70 includes several fasteners 79. Specifically, the cover plate 7006ba of the first housing 7006b has a first through hole 7006x, the circuit board 72 has a second through hole 7006y, the mounting plate 75a has a third through hole (not shown), and the base plate 7006ca has a fourth through hole 7006q. The fasteners 79 pass through the fourth through hole 7006q, the third through hole, the second through hole 7006y, and the first through hole 7006x, thereby fixing the first housing 7006b, the circuit board 72, and the second housing 7006c.

[0039] Therefore, in this embodiment, there are two fasteners 79, and the fasteners 79 pass through through holes in the cover plate 7006ba, the mounting plate 75a and the base plate 7006ca, so that the first housing 7006b, the circuit board 72 and the second housing 7006c are fixed.

[0040] In some other embodiments of this application, the height of the second side plate 7006bb is greater than or equal to one-quarter of the height of the first side plate 7006cb and less than or equal to two-thirds of the height of the first side plate 7006cb.

[0041] In some other embodiments of this application, the height of the second side plate 7006bb is greater than or equal to one-quarter of the height of the first side plate 7006cb and less than or equal to three-quarters of the height of the first side plate 7006cb.

[0042] In some other embodiments of this application, the second region 72b is a rectangular region or a square region.

[0043] In this embodiment, there can be 22 detection electrodes 71 arranged in two columns, with each column containing 11 electrodes on a straight line parallel to each other. Therefore, the overall shape of the arrangement of the detection electrodes 71 is rectangular. The detection electrodes 71 are placed in the second region 72b, so the shape of the second region 72b can be the same as the shape of the arrangement of the detection electrodes 71, that is, the shape of the second region 72b can be rectangular; or the overall shape of the arrangement of the detection electrodes 71 is rectangular, and the shape of the second region 72b can be square; or the overall shape of the arrangement of the detection electrodes 71 is square, and the shape of the second region 72b can be rectangular; or the overall shape of the arrangement of the detection electrodes 71 is square, and the shape of the second region 72b can be square.

[0044] In some other embodiments of this application, the groove 77 is cuboid or cube-shaped.

[0045] Therefore, in this embodiment, the shape of the groove 77 can be the same as the shape of the second region 72b, that is, if the second region 72b is a rectangular region, then the groove 77 can be a cuboid with the same shape and size; or the shape of the groove 77 can be larger than the shape of the second region 72b, that is, if the second region 72b is a rectangular region, then the groove 77 can be a cuboid / cube with a longer length and width, as long as the detection electrodes 71 in the second region 72b are all located on the bottom surface 70062 of the groove 77.

[0046] In some other embodiments of this application, the first side plate 7006cb and the bottom plate 7006ca are integrally connected.

[0047] Please see Figure 6 , Figure 6This is a schematic diagram of the structure of a medical testing device according to an embodiment of this application. In this figure, the medical testing device includes an instrument body, which includes a slot 4301a and a contact electrode 9043. The slot 4301a is used to insert a testing component 70. When the testing component 70 is inserted into the medical testing device, the contact electrode 9043 contacts the testing electrode 71 of the testing component 70.

[0048] Therefore, in this embodiment, the detection electrode 71 of the detection component 70 is located within the groove 77 formed by the recess on the top surface 70061 and at least one side surface of the detection component 70. When the detection component 70 is inserted into the slot of the medical testing device, it drives the contact electrode inside the medical testing device to move toward the detection electrode 71, so that the detection electrode 71 and the contact electrode come into contact, thereby realizing sample detection. At the same time, since the detection electrode 71 is located in the groove 77, the contact electrode inside the medical testing device does not need to avoid the detection electrode 71 on the top surface 70061 of the detection component 70. The distance between the contact electrode inside the medical testing device and the detection electrode 71 on the detection component 70 can be designed to be less than the overall thickness of the detection component 70, which can greatly reduce the dependence of the overall thickness of the detection component 70 on the opening size of the slot of the medical testing device.
