Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, specifically to a connection device suitable for POCT optical modules and external components. Background Technology

[0002] Point-of-care testing (POCT) refers to rapid medical testing technologies performed near or at the patient's bedside. These technologies do not rely on traditional laboratory equipment and can provide results within a short time (minutes to hours), aiding in rapid clinical decision-making. POCT is reshaping healthcare processes through its fast and convenient testing methods, particularly suitable for emergencies or resource-constrained environments. However, its application requires quality control, standardized procedures, and clinical judgment to ensure the reliability of the results.

[0003] To address the aforementioned issues, Chinese Patent Application No. 202411420786.2 discloses an optical module system for a POCT detection device. This disclosed optical module system includes a housing, within which are disposed a first optical path component, a second optical path component, a third optical path component, a fourth optical path component, a first dichroic mirror, and an optical fiber splitter. The first and second optical path components constitute a reflection mechanism, and the third and fourth optical path components constitute a transmission mechanism. Each optical path component includes a light source, a focusing lens, a filter, and a reflection unit arranged sequentially. The reflection units in the first and third optical path components are reflectors, and the reflection units in the third and fourth optical path components are second dichroic mirrors.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-2 As shown, a connection device for POCT optical modules and external components includes a connector 1 and a connection part 3 that cooperates with the connector 1 to fix the external component 2. The external component 2 is fixedly disposed on the connection part 3. The connection part 3 is provided with a plurality of magnetic elements 3023, and the external component 2 is provided with an adapter 2012 that can be attracted by the magnetic elements 3023. The connector 1 is provided with a fixing groove 101, the connection part 3 is inserted into the fixing groove 101, the connector 1 is provided with a locking structure 4 to prevent the connection part 3 from disengaging from the fixing groove 101, and the connection part 3 is provided with a locking part 304 that cooperates with the locking structure 4.

[0028] Furthermore, the connector 1 is fixedly mounted on the optical module, and the connector 1 is part of the optical module. The connector 3 is inserted into the fixing slot 101. The external component 2 is fixed through the connector 3 and is inserted into the fixing slot 101 synchronously with the connector 3.

Multiple adapters 2012 are provided on the external component 2, each corresponding to one of the magnetic elements 3023, and the adapters 2012 can be driven by the magnetic elements 3023. The adsorption adapter 2012 can be an electromagnet, a magnet, a neodymium magnet, or a metal that can be adsorbed by the magnetic component 3023, such as iron or steel, preferably a metal, and more preferably iron. By adsorbing the adapter 2012 set on the external component 2 by the magnetic component 3023 set on the connecting part 3, the external component 2 is fixed on the connecting part 3. At the same time, the connecting part 3 and the external component 2 are inserted into the fixing groove 101 of the connecting seat 1, thereby realizing the connection and fixation of the external component 2. Furthermore, the connecting seat 1 is set on the optical module, ensuring the connection stability between the external component 2 and the optical module, thereby ensuring that the external component 2 will not be abnormally loose or tight.

[0029] In addition, a locking structure 4 is provided on the connecting seat 1, and a locking part 304 is provided on the connecting part 3 to cooperate with the locking structure 4. Through the cooperation of the locking structure 4 and the locking part 304, the connecting part 3 is fixedly locked, thereby preventing the connecting part 3 from disengaging from the fixing groove 101. At the same time, the locking structure 4 is used to unlock the connecting part 3, making it easier to insert and remove the connecting part 3 in the fixing groove 101.

[0030] The connector 1, the connector 3, and the external component 2 are respectively provided with a first light-transmitting hole 103, a second light-transmitting hole 3021, and a third light-transmitting hole 2021; when the connector 3 fixes the external component 2 in the fixing groove 101 of the connector 1, the first light-transmitting hole 103, the second light-transmitting hole 3021, and the third light-transmitting hole 2021 are connected to form a continuous optical path channel that passes through the connector 1, the connector 3, and the external component 2.

[0031] The connecting part 3 includes an integrally formed top block 301 and a fixing block 302 disposed on the lower surface of the top block 301. The fixing block 302 is provided with a plurality of first mounting holes 3022. The magnetic element 3023 is disposed in the first mounting holes 3022. Furthermore, the size of the top block 301 is adapted to the size of the connecting seat 1. The fixing block 302 is disposed on one side of the lower surface of the top block 301, and the outer side of the fixing block 302 is flush with the side of the top block 301. The length of the fixing block 302 is the same as the depth of the fixing groove 101. The first mounting holes 3022 are arranged along the thickness direction of the fixing block 302, and the magnetic element 3023 is fixedly disposed in the corresponding first mounting holes 3022.

[0032] In addition, the second light-transmitting hole 3021 is disposed on the fixing block 302 and passes through the fixing block 302. Several first mounting holes 3022 are distributed on the upper and lower sides of the second light-transmitting hole 3021, thereby ensuring that the external component 2 is subjected to uniform force when adsorbing the external component 2, thus making the external component 2 more firmly fixed.

[0033] The external component 2 includes a main body 201 and a connecting post 202 connected to the main body 201. The main body 201 has second mounting holes 2011 corresponding to the first mounting holes 3022. The adapter 2012 is disposed in the second mounting holes 2011.

The second mounting holes 2011 are arranged along the thickness direction of the main body 201, and the positions of several second mounting holes 2011 correspond to several first mounting holes 3022. The adapter 2012 is fixedly installed in the second mounting holes 2011. The adapter 2012 is attracted by the magnetic element 3023 in the first mounting hole 3022, so that the main body 201 of the external component 2 is attached to the fixing block 302. The sum of the thickness of the main body 201 and the thickness of the fixing block 302 is equal to the width of the fixing groove 101, so that the connecting part 3 and the external component 2 are more stable when inserted into the fixing groove 101 and will not shake.

[0034] In addition, the third light-transmitting hole 2021 is disposed on the connecting post 202 along the axial direction of the connecting post 202, and the third light-transmitting hole 2021 is disposed through the connecting post 202 and the main body 201.

[0035] The lower surface of the top block 301 is also provided with a limiting block 303 for limiting the main body 201. A fixed space for connecting the main body 201 is formed between the limiting block 303 and the fixing block 302. The end of the limiting block 303 is provided with an arc-shaped part 3031 that is adapted to the outer wall of the connecting column 202. Furthermore, the limiting block 303 is located on the opposite side of the fixing block 302, and the outer side of the limiting block 303 is flush with the other side of the top block 301. The limiting block 303 is arranged parallel to the fixing block 302, and the bottom end of the limiting block 303 is located at the second light-transmitting hole 302. Above 1, thus avoiding the limiting block 303 from blocking the second light-transmitting hole 3021; ​​in addition, a fixed space is provided between the limiting block 303 and the fixing block 302. When the main body 201 is attached to the fixing block 302, the main body 201 is located in the fixed space. The width of the fixed space is the same as the thickness of the main body 201. An arc-shaped part 3031 that is adapted to the outer wall of the connecting column 202 is formed at the end of the main body 201, thereby realizing the fixed limiting of the main body 201 and the connecting column 202, and ensuring the stability of the connection of the external component 2.

[0036] A limiting groove 102 adapted to the limiting block 303 is formed on the connecting seat 1. The limiting block 303 and the connecting post 202 are both inserted into the limiting groove 102. Furthermore, the limiting groove 102 is set on the side wall of the connecting seat 1. The width of the limiting groove 102 is the same as the width of the limiting block 303, the thickness of the limiting groove 102 is the same as the thickness of the side wall of the connecting seat 1, and the depth of the limiting groove 102 is greater than the sum of the length of the limiting block 303 and the diameter of the connecting post 202.

[0037] In addition, the first light-transmitting hole 103 is provided on the side wall of the connecting seat 1 on the side opposite to the limiting groove 102, and the first light-transmitting hole 103 is connected to the fixing groove 101. When the connecting part 3 and the external component 2 are inserted into the fixing groove 101, the first light-transmitting hole 103, the second light-transmitting hole 3021 and the third light-transmitting hole 2021 are connected, thereby facilitating the passage of the optical path.

[0038] The locking part 304 is disposed on opposite sides of the fixing block 302. A gap 305 is formed between the locking part 304 and the fixing block 302. The bottom end of the locking part 304 is provided with a protrusion 3041 extending outward. Both protrusions 3041 are interference-fitted with the fixing groove 101. Furthermore, the length of the locking part 304 is less than the length of the fixing block 302. A gap 305 is provided between the locking part 304 and the fixing block 302. The protrusion 3041 is disposed on the outer side of the bottom end of the locking part 304 and extends outward along the width direction of the fixing block 302. The distance between the two protrusions 3041 is greater than the length of the fixing groove 101, thus achieving an interference fit between the protrusion 3041 and the groove wall of the fixing groove 101, so that the connecting part 3 will not loosen when inserted into the fixing groove 101.

[0039] The locking structure 4 includes a button groove 402 formed in the wall of the fixing groove 101. A button 401 is slidably disposed in the button groove 402 to push the protrusion 3041 to release the locking state. Furthermore, the button groove 402 is disposed on the groove walls on opposite sides of the fixing groove 101 and extends through the entire groove wall. The button 401 is slidably connected in the button groove 402. Pressing the button 401 causes the button to push the protrusion 3041 to move, thereby causing the locking part 304 to bend and deform, thereby releasing the locking state of the connecting part 3. In addition, the locking part 304 can be an elastic material or a non-elastic material that can be bent and deformed. The locking part 304 bends and deforms in the direction of the gap 305 under the push of the button 401. The bending deformation is not large, and it is enough for the protrusion 3041 to disengage from the locking structure 4 to release the locking state of the connecting part 3.

[0040] In addition, the width of the button groove 402 is divided into two widths along the length direction of the button groove 402. The width of the part of the button groove 402 near the fixing groove 101 is smaller than the width of the part near the outer wall of the connecting seat 1. The width of the button 401 is adapted to the width of the button groove 402. By setting the button groove 402 into two different widths, the pressing distance of the button 401 is limited, thereby avoiding excessive pressing of the button 401 on the protrusion 3041 and causing the locking part 304 to break.

[0041] The button 401 is provided with an anti-detachment groove 4011 along the length of the button 401. The connecting seat 1 is provided with an anti-detachment hole 4041 communicating with the anti-detachment groove 4011. The anti-detachment hole 4041 is provided with an anti-detachment rod 404 connected to the anti-detachment groove 4011. Furthermore, the anti-detachment groove 4011 is a waist-shaped hole structure. The anti-detachment hole 4041 is provided through the entire connecting seat 1. The anti-detachment rod 404 is provided in the anti-detachment hole 4041 and passes through the anti-detachment groove 4011. Through the cooperation between the anti-detachment rod 4041 and the anti-detachment groove 4011, the button 401 is prevented from detaching from the button groove 402.

The protrusion 3041 is located within the locking groove 405, and the locking groove 405 communicates with the button groove 402. The button 401 extends outward from the button groove 402. Furthermore, the locking groove 405 is disposed horizontally, and its length is greater than the width of the protrusion 3041, its depth is greater than the thickness of the protrusion 3041, and the locking groove 405 is disposed on the wall of the fixing groove 101. The locking groove 405 communicates with the button groove 402. The button 401 is connected, with one end in the button groove 402. Specifically, this end is located at the junction of the button groove 402 and the snap-fit ​​groove 405. The other end of the button 401 extends out of the button groove 402 along the length of the button 401, and the length of the extended part is greater than the depth of the snap-fit ​​groove 405. When the connecting part 3 is inserted into the fixing groove 101, the protrusion 3041 snaps into the snap-fit ​​groove 405, thereby locking the connecting part 3. When the locking state is to be released, the button 401 is pressed to push the protrusion 3041 out of the snap-fit ​​groove 405, thereby releasing the locking state of the connecting part 3.

[0044] Example 2:

[0045] like Figures 5-6As shown, in this embodiment, the locking structure 4 further includes a locking strip 403 disposed on the wall of the fixing groove 101 for engaging the protrusion 3041.

The button 401 is located at the same height as the protrusion 3041, and the end of the button 401 is flush with the wall of the fixing groove 101, while the other end extends outward from the button groove 402. Furthermore, the locking strip 403 is arranged horizontally. The length of the locking strip 403 can be less than the width of the protrusion 3041, greater than the width of the protrusion 3041, or equal to the width of the protrusion 3041. Preferably, the length of the locking strip 403 is equal to the width of the protrusion 3041, and the width of the locking strip 403 is equal to the thickness of the protrusion 3041. The locking bar 403 is located above the button groove 402. When the connecting part 3 is inserted into the fixing groove 101, the protrusion 3041 is located below the locking bar 403, and the upper surface of the protrusion 3041 contacts the lower surface of the locking bar 403, thereby locking the connecting part 3. At this time, the protrusion 3041 is positioned directly opposite the button groove 402, the end of the button 401 is flush with the groove wall of the fixing groove 101, and the other end of the button 401 extends outward from the button groove 402 along the length direction of the button 401, and the length of the extended part is greater than the width of the locking bar 403. When the locking state is to be released, the button 401 is pressed to push the protrusion 3041 out from under the locking bar 403, thereby releasing the locking state of the connecting part 3.
