[0022] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application.

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

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or connected through an intermediate medium. For ordinary technicians in this field, if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of this application, the directional indications are only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0025] See also Figure 1 , Figure 1 Schematic diagram of the structure of the first embodiment of the test tube adapter assembly provided by the present application. Figure 1 As shown, the embodiment of the present application first proposes a test tube adapter component, which is applied to a test tube rack 1 adapted by a sample analyzer. The test tube adapter component is used as a transfer container for a calibration sample tube 30, so that the calibration sample tube 30 can be directly placed on the test tube rack 1. Among them, the test tube rack 1 is a conventional test tube rack, that is, a conventional test tube rack can also be used to place tubes to be tested, for example, venous blood test tubes. The sample analyzer can receive the test tube rack 1 through a normal test process to obtain multiple calibration sample tubes 30 and perform multi-point calibration, thereby improving the calibration efficiency.

[0026] Specifically, the test tube adapter assembly includes an adapter seat 10 and a cover 20. The adapter seat 10 is placed on a test tube rack 1 corresponding to the sample analyzer. The adapter seat 10 forms a first accommodating cavity, and the first accommodating cavity is used to place a calibration sample tube 30. The cover 20 is detachably connected to the adapter seat 10, and the calibration sample tube 30 is placed in the first accommodating cavity. The cover 20 is assembled with the adapter seat 10 to carry the calibration sample tube 30 through the test tube adapter assembly and allow the calibration sample tube 30 to be received by the sample analyzer through the test tube rack 1. The sample analyzer receiving the calibration sample tube 30 can be understood as the calibration sample tube 30 being transported to the inside of the sample analyzer, or the calibration sample tube 30 being transported to a position corresponding to the sample analyzer by the injection assembly. At this time, the calibration sample tube 30 is located outside the sample analyzer, so that the sample analyzer obtains the sample in the calibration sample tube 30.

[0027] Among them, the calibration sample tube 30 of this embodiment is an original sample bottle loaded with calibration samples. The calibration sample tube 30 may be different from the sample tube used for conventional tests in terms of size, shape, specification, material, etc., so that the calibration sample tube 30 cannot be directly placed on the test tube rack 1 corresponding to the sample analyzer. Therefore, the calibration sample tube 30 of this embodiment is placed in the test tube adapter component, and the test tube control component is placed in the test tube rack 1, so that the calibration sample tube 30 can be adapted and placed in the test tube rack 1. After the test tube rack 1 with the calibration sample tube 30 is received by the sample analyzer, the sample analyzer can execute the normal test process and analyze and calibrate the calibration sample to automatically realize multi-point calibration, reduce manual intervention, and improve calibration efficiency; at the same time, through the test tube adapter component, the test tube rack can be shared, which improves the convenience of operation.

[0028] It is understandable that after receiving the test tube rack 1, the sample analyzer usually needs to use a mechanical clamp to grab the test tube on the test tube rack 1 and perform a scanning operation. In order to prevent the calibration sample tube 30 from relatively rotating when the mechanical clamp grabs the test tube adapter assembly, resulting in a scanning error, the test tube adapter assembly of this embodiment is provided with a detachably connected adapter seat 10 and a cover 20. The adapter seat 10 is used to receive the calibration sample tube 30. The cover 20 can move integrally with the adapter seat 10 when connected to the adapter seat 10. The mechanical clamp can directly grab the cover 20 and move and / or rotate it to achieve a scanning operation.

[0029] In the embodiment of the present application, the test tube adapter assembly places the calibration sample tube 30 on the adapter seat 10 and assembles the cover 20 to the adapter seat 10, so that the calibration sample tube 30 can be directly placed on the test tube rack 1 through the test tube adapter assembly, without the need to transfer the calibration sample, thereby reducing the waste of reagents caused by the transfer of the calibration sample; there is no need to select a specific test tube rack and a special bottle to carry the calibration sample; the test tube adapter assembly can share a conventional test tube rack with the tube to be tested; and the sample analyzer can directly receive multiple calibration sample tubes 30 placed on the test tube rack 1 and perform multi-point calibration, thereby reducing the complexity of the calibration process and the calibration cost of the sample analyzer, and improving the calibration efficiency of the sample analyzer.

Figure 2-4 As shown, the adapter seat 10 includes a base 110 and a first fastening member 120, the first fastening member 120 is arranged on the base 110, the cover member 20 includes a cover body 210 and a second fastening member 220, the second fastening member 220 is arranged on the cover body 210, and the first fastening member 120 is fastened with the second fastening member 220 to realize the assembly of the adapter seat 10 and the cover member 20.

[0031] Specifically, the adapter seat 10 and the cover member 20 are detachably connected by the fastening of the first fastening member 120 and the second fastening member 220. The base 110 of the adapter seat 10 is provided with a first accommodating cavity for receiving the calibration sample tube 30, and the first fastening member 120 is provided on the base 110. The cover body 210 of the cover member 20 is provided with a second accommodating cavity, and when the second fastening member 220 is fastened with the first fastening member 120, the calibration sample tube 30 is placed in the first accommodating cavity and is located in the second accommodating cavity, so as to realize the assembly of the adapter seat 10 and the cover member 20 and realize the placement of the calibration sample tube 30 in the test tube adapter assembly.

[0032] In one embodiment, the first fastening member 120 is disposed on the outer side wall of the base 110, and the first fastening member 120 may be a boss on the outer side wall, and the second fastening member 220 is disposed on the inner side wall of the cover body 210 and may form at least one recessed position, and the first fastening member 120 and the second fastening member 220 may be fastened together by the cooperation between the boss and the recessed position during the pushing or sliding process. In another embodiment, the second fastening member 220 may also be at least one boss disposed at intervals; when the cover member 20 is pushed or slid, the boss of the second fastening member 220 may pass over the boss of the first fastening member 120 under the action of an external force, and the boss of the second fastening member 220 may be placed on the side of the boss of the first fastening member 120, so as to be fastened together by the clamping connection between the two bosses. In other possible implementations, the first fastening member 120 and the second fastening member 220 can be connected by a push-motion buckle, a slide-motion buckle, a flip-motion buckle, a twist-motion buckle or a rotation-motion buckle, etc., which is not specifically limited here.

[0033] In the embodiment of the present application, the test tube adapter assembly is fastened with the second fastening member 220 and the first fastening member 120, so that the adapter seat 10 and the cover member 20 are detachably connected. The structure is simple and easy to implement, so that the calibration sample tube 30 can be directly placed on the test tube rack 1 through the test tube adapter assembly, thereby reducing the cost of use.

[0034] Optionally, in one embodiment, Figure 2 As shown, the cover member 20 also includes a protruding end 250, which is arranged on the end surface of the cover body 210 close to the base 110, and the second fastening member 220 is arranged on the protruding end 250. The adapter seat 10 also includes a first boss 130, which surrounds the outer wall arranged on the base 110 and forms a notch, and the first fastening member 120 is arranged on the first boss 130. The cover member 20 is aligned and positioned with at least one side end of the notch by the protruding end 250.

[0035] At this time, the second fastening member 220 is arranged at the position of the protruding end 250, and the first fastening member 120 is arranged at the first boss 130, so that the first fastening member 120 and the second fastening member 220 can be fastened directly during the alignment process. Alternatively, the second fastening member 220 is arranged on the inner wall of the cover body 210, and the first fastening member 120 is arranged on the outer wall of the base 110. The first fastening member 120 and the second fastening member 220 can be fastened through the cooperation of the boss and the recessed position or through the two bosses, so as to realize the assembly of the adapter 10 and the cover member 20.

[0036] In one embodiment, specifically, there are two protruding ends 250 , a recess is formed between the two protruding ends 250 , and the two protruding ends 250 are aligned with the two side ends of the notch respectively, that is, the recess between the two protruding ends 250 is aligned with the notch.

[0037] In one embodiment, specifically, the protruding end 250 is used for positioning and restraining, and a groove is formed on the side of the protruding end 250 for correspondingly accommodating the first boss 130. The first boss 130 has a notch formed on the outer wall of the base 110 corresponding to the accommodating protruding end 250, so that the protruding end 250 and the first boss 130 can be aligned and positioned. After the positioning is completed, the cover 20 moves downward and approaches the adapter seat 10 under the action of external force, and the cover 20 and the adapter seat 10 abut against each other under the action of external force, so that the second buckle 220 and the surface of the first buckle 120 interfere and buckle.

[0038] In the embodiment of the present application, the test tube adapter assembly is positioned by aligning the protruding end 250 with the notch, so that the first fastening member 120 and the second fastening member 220 can be fastened at the appropriate position to complete the assembly of the cover member 20 and the adapter seat 10, thereby improving the assembly efficiency of the adapter seat 10 and the cover member 20.

[0039] Alternatively, in another embodiment, Figure 3 and Figure 4 As shown, the cover member 20 includes a first toothed end 260, which is arranged on the end surface of the cover body 210 close to the base 110, and the adapter seat 10 also includes a second toothed end 150, which is arranged on the end surface of the base 110 close to the cover body 210, and the shape and size of the second toothed end 150 correspond to those of the first toothed end 260.

[0040] The first fastening member 120 is arranged around the outer wall of the base 110, and the second fastening member 220 is arranged around the inner wall of the cover body 210. The cover member 20 moves axially along the adapter seat 10 under the external force. When the tooth surface of the first toothed end 260 contacts the tooth surface of the second toothed end 150, the first toothed end 260 and the second toothed end 150 undergo relative displacement movement under the force, so that the second fastening member 220 interferes with the first fastening member 120 under the force, so that the first fastening member 120 and the second fastening member 220 are fastened.

[0041] Specifically, the tooth tips of the first toothed end 260 and the second toothed end 150 can be set to be an arc shape, so that when any tooth tip of the first toothed end 260 and the second toothed end 150 contacts the tooth tip or the toothed inclined surface of the other, the interaction force between the tooth tips or the interaction force between the tooth tips and the toothed inclined surface can guide the two to move relative to each other, and finally the first toothed end 260 and the second toothed end 150 are meshed with each other and the cover 20 is aligned with the adapter seat 10.

[0042] The first fastening member 120 is disposed around the outer wall of the base 110 to form a continuous annular boss. A second accommodating cavity is formed at the bottom of the cover body 210, and a second fastening member 220 is disposed on the inner wall of the cover body 210 near the second accommodating cavity. The second fastening member 220 is disposed around the inner wall of the cover body 210 and forms a plurality of spaced bosses or recesses, so that the second fastening member 220 and the first fastening member 120 are in contact and fastened at a plurality of non-continuous nodes. At this time, the plurality of bosses or recesses of the second fastening member 220 can be distributed at a plurality of positions of the same radial section inside the cover body 210, so as to reduce the fastening area of ​​the first fastening member 120 and the second fastening member 220, thereby reducing the damage to the second fastening member 220 caused by the fastening force of the first fastening member 120, and improving the stability and durability of the second fastening member 220.

[0043] It can be understood that the test tube adapter assembly of the present embodiment can be positioned by the offset movement of the first toothed end 260 and the second toothed end 150, so that when the user is assembling the cover 20 and the adapter seat 10, they can be docked and fastened at any angle or direction. The user only needs to push the cover 20 to move in the axial direction so that the spaced second fastening member 220 can be accurately fastened with the first fastening member 120 to achieve non-directional covering at any position, thereby improving the stability of the second fastening member 220 and the assembly efficiency.

[0044] In one embodiment, a groove 140 is provided on the side wall of the adapter seat 10, and the groove 140 is connected to the first accommodating cavity. The calibration sample tube 30 is placed in the first accommodating cavity, and an identification code is provided on the outer wall of the calibration sample tube 30. The groove 140 is used to display the identification code when the calibration sample tube 30 is placed in the first accommodating cavity, so that the sample analyzer can scan the identification code.

[0045] Specifically, a slot 140 is provided on the side wall of the base 110 of the adapter 10, and the slot 140 is connected to the first accommodating cavity and allows part of the calibration sample tube 30 to be exposed to the air. The outer wall of the calibration sample tube 30 is usually provided with an identification code, and the slot 140 of the adapter 10 is used to reveal the identification code, so that when the mechanical clamp grabs the test tube scanning component, the sample analyzer can scan the identification code of the calibration sample tube 30 through the scanning component, so as to determine the calibration sample through the information obtained by scanning, and perform the subsequent multi-point calibration process.

[0046] In one embodiment, the cover body 210 of the cover 20 is formed with a second accommodating cavity. When the calibration sample tube 30 is placed on the adapter seat 10 and the cover 20 is assembled with the adapter seat 10, the first accommodating cavity and the second accommodating cavity are connected, and a gap layer 230 is formed in the second accommodating cavity, so that the inner wall of the cover 20 and the calibration sample tube 30 are not in contact.

[0047] Specifically, the second accommodating cavity of the cover 20 is used to accommodate the top of the calibration sample tube 30, and the first accommodating cavity of the adapter 10 is used to receive the bottom of the calibration sample tube 30 and form a support. When the calibration sample tube 30 is placed on the adapter 10 and the cover 20 is assembled with the adapter 10, the first accommodating cavity is connected with the second accommodating cavity, and a gap layer 230 is formed between the second accommodating cavity of the cover 20 and the calibration sample tube 30, so that the inner wall of the cover 20 and the calibration sample tube 30 do not contact each other. When the cover 20 is assembled with the adapter 10, the cover will not be unstable due to the obstruction of the calibration sample tube 30, thereby improving the stability of the test tube adapter assembly.

[0048] In one embodiment, a through hole 240 is provided at one end of the cover 20 away from the adapter seat 10 . The through hole 240 is used for a sampling needle of a sample analyzer to pass through so that the sampling needle can absorb the calibration sample of the calibration sample tube 30 .

[0049] Specifically, the cover 20 is provided with a through hole 240 extending in the axial direction at the top away from the adapter seat 10, and the through hole 240 is used for the sampling needle of the sample analyzer to pass through. After the test tube adapter assembly receiving the calibration sample tube 30 is placed on the test tube rack 1, the sample analyzer obtains at least one calibration sample tube 30 on the test tube rack 1 through the sampling assembly 3, and controls the sampling needle of the sampling assembly to probe downward, and the sampling needle passes through the through hole 240 and absorbs the calibration sample of the calibration sample tube 30, and the detection assembly of the sample analyzer tests the calibration sample tube 30 to perform multi-point calibration.

[0050] In this embodiment, a through hole 240 for the sampling needle to pass through is provided at one end of the cover 20 away from the adapter seat 10. The sampling needle of the sample analyzer penetrates below the liquid level of the calibration sample tube 30 through the through hole 240 and absorbs the calibration sample, so that the sample analyzer can obtain the calibration sample in the calibration sample tube 30 without transferring the calibration sample, thereby reducing the complexity of the calibration process and improving the calibration efficiency of the sample analyzer.

[0051] Optionally, the cross-sectional area of ​​the through hole 240 is smaller than the cross-sectional area of ​​the bottom of the calibration sample tube 30 .

[0052] Specifically, the cross-sectional area of ​​the through hole 240 is the opening area. The end of the calibration sample tube 30 close to the bottom of the adapter seat 10 has an end face, and the cross-sectional area of ​​the end face is larger than the cross-sectional area of ​​the through hole 240, so that the calibration sample tube 30 cannot enter or exit from the through hole 240 of the cover 20, thereby improving the stability of the calibration sample tube 30 in the test tube adapter assembly, reducing the fall and leakage of the calibration sample caused by the fall of the calibration sample tube 30, incorrect assembly, etc., and improving the reliability of the calibration process.

[0053] Optionally, the calibration sample tube 30 includes a tube body 310 and a second boss 320 arranged around the tube body 310, and the adapter seat 10 includes a base 110, the base 110 forms a first accommodating cavity, the radial dimension of the first accommodating cavity is a first dimension, the radial dimension of the tube body 310 is a second dimension, the sum of the radial dimensions of the tube body 310 and the second boss 320 is a third dimension, the first dimension is greater than the second dimension and the first dimension is less than or equal to the third dimension.

[0054] Specifically, the first size, the second size, and the third size are used to indicate the size of the corresponding object or space in a certain cross section. When the first accommodating cavity, the tube body 310, and the second boss 320 are cylindrical or approximately cylindrical in shape, the first size, the second size, and the third size may be the diameter or radius of the position; when the first accommodating cavity, the tube body 310, and the second boss 320 are square or other irregular shapes, the first size, the second size, and the third size may be the maximum distance from the edge of a certain cross section to the central axis, which is not specifically limited here.

[0055] In the embodiment of the present application, the first dimension is greater than the second dimension, so that the first accommodating cavity can accommodate the calibration sample tube 30; the first dimension is less than or equal to the third dimension, that is, the second boss 320 of the calibration sample tube 30 is in contact with or interference fit with the inner wall of the first accommodating cavity, so as to fix the calibration sample tube 30 through the contact resistance between the adapter seat 10 and the calibration sample tube 30, avoid relative rotation of the calibration sample tube 30 in the adapter seat 10, ensure that the sample analyzer can accurately scan the test tube adapter assembly, and improve the reliability of the test tube adapter assembly.

[0056] In other embodiments, the roughness of at least a portion of the inner wall of the first accommodating cavity or the outer wall of the calibration sample tube 30 can be adjusted to increase the contact resistance between the calibration sample tube 30 and the adapter seat 10 and avoid relative rotation of the calibration sample tube 30 in the adapter seat 10, which is not specifically limited here.
