The test tube transfer device is a crucial component of the blood collection management system, used for transporting test tubes.

[0003] In existing transmission relay components, due to the long guide rails of the relay components, the sliders on the guide rails are used as fulcrums, which easily leads to warping and deformation, causing the guide rails to form an angle with the base plate, affecting the normal transport of test tubes by the relay components. Summary of the Invention

[0004] This invention provides a transmission test tube relay component to solve the technical problem that the guide rail is prone to warping and deformation in the prior art.

[0015] According to a specific embodiment of the present invention, both the base plate and the panel are grooved plates with the groove portions facing each other to form an accommodating space for accommodating the slider and the slider.

[0016] According to a specific embodiment of the present invention, the relay component further includes:

[0017] The motor is fixedly assembled with the base plate;

[0018] The driven wheel is fixed to the base plate and located on the side away from the motor;

[0038] Please see Figures 1-2 This invention provides a test tube adapter, which mainly includes a base 10, a first test tube holder 20, a second test tube holder 30, and a fixing base 40.

[0039] The first test tube holder 20 is fixedly connected to the base 10 and is used to insert a first type of test tube 101 (such as a commonly used ordinary blood collection tube). The second test tube holder 30 is detachably connected to the base 10 and is used to insert a second type of test tube 201 / 202 / 203 (such as a terminal blood test tube with a conical bottom).

[0040] The fixed base 40 is fixedly connected to the base 10 and is arranged adjacent to the first test tube holder 20 at intervals. The second test tube holder 30 is detachably connected to the fixed base 40.

[0041] The second test tube holder 30 includes an insert post 31 and a limiting protrusion 32 located on the outer wall of the insert post 31. The upper part of the insert post 31 is a quasi-square prism, consistent with the first test tube holder 20, and the lower part is a quasi-cylindrical shape.

[0042] The fixing base 40 includes a surrounding wall 41 and an insertion cavity 42 disposed within the surrounding wall 41. The insertion cavity 42 matches the insertion post 31 on the second test tube holder 30. The length of the insertion post 31 is less than the depth of the insertion cavity 42 so that when the second test tube holder 30 is inserted into the fixing base 40, the bottom of the second test tube holder 30 is spaced apart from the bottom of the base 10, so that the second test tube holder 30 can be easily and smoothly assembled into place. If the length of the insertion post 31 is greater than or equal to the depth of the insertion cavity 42, the second test tube holder 30 is prone to tilting or tilting.

[0043] A limiting groove 411 is provided on the enclosure 41. The limiting groove 411 matches the limiting protrusion 32 on the second test tube holder 30. After the second test tube holder 30 is inserted and connected to the fixed seat 40, the cooperation of the limiting groove 411 and the limiting protrusion 32 can prevent the second test tube holder 30 from rotating relative to the fixed seat 40, thus playing a positioning role.

[0044] The opening end of the limiting groove 411 is provided with a symmetrical first guide slope 412, and the free end of the limiting protrusion 32 is provided with a symmetrical second guide slope 321. During the process of inserting the second test tube seat 30 into the connecting fixed seat 40, the first guide slope 412 and the second guide slope 321 match each other, making the insertion and connection of the second test tube seat 30 and the fixed seat 40 smoother.

[0045] The base 10 and the first test tube holder 20 can be integrally formed or assembled. The fixed seat 40 and the base 10 can be integrally formed or assembled. The second test tube holder 30 can be integrally formed or CNC machined.

[0046] The base 10 is provided with a through hole 11, which is located between the fixed base 40 and the first test tube base 20. The through hole 11 can be used to fix the test tube adapter.

[0047] When the first test tube holder 20 is fitted with a first-type test tube 101, the distance from the bottom surface of the inner cavity of the first-type test tube 101 to the bottom surface of the base 10 is Hd. The second test tube holder 30 has various sizes (different heights) to accommodate various sizes of second-type test tubes 201. When the various sizes of the second test tube holder 30 are fitted onto the fixed base 40, the distance from the bottom surface of the base 10 to the top of the second test tube holder 30 is H1. The height of the various sizes of second-type test tubes 201 / 202 / 203 is H2. The distance from the bottom surface of the inner cavity of the various sizes of second-type test tubes 201 / 202 / 203 to the bottom of the various sizes of second-type test tubes 201 / 202 / 203 is H3. Here, Hd is a constant, while H1, H2, and H3 are variable values.

[0048] When different sizes of the second test tube holder 30 and the second type of test tube 201 / 202 / 203 are replaced, Hd, H1, H2, and H3 satisfy the formula: H1-H2+H3=Hd. This ensures that when the instrument inserts the second type of test tube 201 / 202 / 203 to take samples, the bottom surface of the inner cavity of the second type of test tube 201 / 202 / 203 is flush with the bottom surface of the inner cavity of the first type of test tube 101. The reference insertion depth of the sampling needle of the instrument is consistent. When the instrument can draw samples normally without touching the bottom surface of the inner cavity of the first type of test tube 101, the same insertion depth will also not touch the bottom surface of the inner cavity of the second type of test tube 201 / 202 / 203 and will be able to draw samples normally.

[0049] An embodiment of the present invention also provides a sample analyzer, which includes the aforementioned test tube adapter.

[0050] In summary, those skilled in the art will readily understand that the test tube adapter provided by the present invention, through the detachable connection between the second test tube holder 30 and the base 10, allows for convenient replacement of the second test tube holder 30 according to the specifications and models of the test tubes, thereby adapting to a variety of test tubes of different specifications and making the application range of this test tube adapter more extensive.

[0051] Please see Figures 3-5 This invention provides a relay component that can be used to transmit reagents for medical testing or other liquid reagents. The relay component mainly includes a base plate 100, a support block 200, a slider and slide rail assembly 300, and a panel 400.

[0052] An opening 110 is provided at one end of the base plate 100, and a support block 200 is fixed to the base plate 100 at the opening 110. The slider and slide rail assembly 300 includes a slider 310 and a slide rail 320. The slider 310 is assembled and fixed on the base plate 100 by the support block 200, and the slide rail 320 is slidably engaged with the slider 310. The panel 400 is fixed on the slide rail 320.

[0053] A folding plate 120 extends integrally from the opening 110 of the base plate 100. The folding plate 120 can be an independent plate or integrally formed with the base plate 100. The folding plate 120 is provided with a first slotted hole 121, and the support block 200 is provided with a fixing hole 210 corresponding to the first slotted hole 121. The first slotted hole 121 can be used to cooperate with a fastener (such as a screw) to support the adjustment of the fixed position of the support block 200. There is no limit to the number of first slotted holes 121, which can be one or two. In this embodiment, the position of the support block 200 needs to be adjusted through the first slotted holes 121. Considering the convenience of adjustment and the firmness of fixation, the number of first slotted holes 121 is set to two.

[0054] An L-shaped plate 130 is fixedly connected to the base plate 100 at the opening 110. One bent edge of the L-shaped plate 130 has a second slotted hole 131. The second slotted hole 131 connects to the corresponding fixing hole 210 of the support block 200 via a fastener (such as a screw), thereby adjusting the fixed position of the support block 200. The number of second slotted holes 131 is not limited; it can be one or two. In this embodiment, the position of the support block 200 needs to be adjusted through the second slotted holes 131. Considering ease of adjustment and secure fixing, the number of second slotted holes 131 is set to two. The other bent edge of the L-shaped plate 130 has a second slotted hole 132, which is used for fixed connection to the base plate 110.

[0055] Specifically, screws can be used to connect the first slotted hole 121 and the fixing hole 210, and the second slotted hole 131 and the fixing hole 210. By controlling the tightness of the screws, the vertical angle of the support block 200 can be adjusted, thereby adjusting the parallelism of the slide rail 320. The support block 200 can be a relatively thick machined part. When the slide rail 320 slides on the slider 310, the connection between the slider 310 and the support block 200 allows the pressure exerted by the slide rail 320 on the slider 310 to act on both the slider 310 and the support block 200. This increases the compressive strength of the support point of the slide rail 320 on the slider 310, making the slide rail 320 less prone to warping and deformation, thus ensuring the normal transport of test tubes by the relay component.

[0056] Furthermore, an auxiliary installation adjustment block can be provided at the end of the base plate 100. When adjusting the parallelism of the slide rail 320 by adjusting the angle of the support block 200, the auxiliary installation adjustment block can act on the end of the slide rail 320 to ensure the overall parallelism of the slide rail 320. After the adjustment is completed, the auxiliary installation adjustment block can be removed.

[0057] The relay assembly also includes a sensor assembly 500, which is an optocoupler sensor used to detect the position of the panel. The sensor assembly 500 includes a first sensor 510 and a second sensor 520. The first sensor 510 is mounted on the end of the base plate 100 near the support block 200. The support block 200 has a clearance notch 220 to avoid the photoelectric switch and mounting screws of the first sensor 510. The second sensor 520 is mounted on the side of the base plate 100 away from the first sensor 510 and is used to detect the initial position of the panel 400.

[0058] The panel 400 is provided with multiple notches 410, and the optocoupler of the sensor assembly 500 cooperates with the multiple notches 410 to sense the position of the panel 400.

[0059] Both the base plate 100 and the panel 400 are grooved plates, and the grooves are opposite each other to form a receiving space for accommodating the sliders 310 and 320. Both the base plate 100 and the panel 400 can be sheet metal parts. The base plate 100 has at least one bent portion connected to the support block 200. In this embodiment, the base plate 100 has two bent portions, namely a folded plate 120 and an L-shaped folded plate 130, both of which are connected to the support block 200. The folded plate 120 and the L-shaped folded plate 130 are arranged opposite each other. This preferred arrangement of the two bent portions opposite each other has a further strengthening effect, so that the pressure on the slide rail 320 can be applied more evenly to the slider 310 and the support block 200, thereby making the slide rail 320 less prone to warping and deformation, thus ensuring the normal delivery of test tubes by the relay component.

[0060] The relay assembly also includes a motor drive assembly 600, which includes a motor 610, a driven wheel 620, a drive belt 630, and a drive component 640. The motor 610 is fixedly assembled with the base plate 100, the driven wheel 620 is fixed with the base plate 100 and located on the side away from the motor 610, the drive belt 630 is sleeved between the motor 610 and the driven wheel 620, and the drive component 640 is fixed with the drive belt 630 for driving the slide rail 320 so that the slide rail 320 slides relative to the slider 310.

[0061] The relay assembly includes a test tube adapter assembly 700, which is mounted on a panel 400. The test tube adapter 700 includes a base 10, a first test tube holder 20, a second test tube holder 30, and a fixing base 40. The first test tube holder 20 is fixedly connected to the base 10 and is used to insert a first type of test tube 101. The second test tube holder 30 is detachably connected to the base 20 and is used to insert second type test tubes 201 / 202 / 203. The fixing base 40 is fixedly connected to the base 10 and is arranged adjacent to the first test tube holder 20 at intervals. The second test tube holder 30 is detachably connected to the fixing base 40.

[0062] An embodiment of the present invention also provides a sample analyzer, which includes the aforementioned relay component.

[0063] In summary, those skilled in the art will readily understand that the relay component provided by the present invention, by setting a support block 200 at the bottom of the slider 310, and using the slider 310 and the support block 200 as fulcrums during the sliding process of the slide rail 320, enhances the compressive strength of the fulcrum, making the slide rail 320 less prone to warping and deformation, thereby ensuring the normal delivery of test tubes by the relay component.

[0064] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention.
