Description

Technical Field

[0001] The present invention relates to the field of adapters, and particularly to a test tube adapter suitable for immunoassay. Background Art

[0002] Venous blood and peripheral blood are commonly used blood test specimens in clinical practice. With the continuous development and improvement of modernization, micro-quantification, and convenience of laboratory medicine technology, the application of peripheral blood is becoming more and more extensive. Therefore, the test tubes for holding peripheral blood are quite different from the conventional blood collection tube specifications and are much smaller than the conventional blood collection tubes in terms of conventional dimensions. Therefore, after collecting peripheral blood, it is necessary to put it into a detection instrument for testing, so a suitable peripheral blood vessel is required for holding.

[0003] However, there are certain problems with the current adapters for peripheral blood vessels. First, during testing, the adapter for holding the peripheral blood vessel needs to position the peripheral blood vessel to fix it and prevent it from moving during the testing process, which is not convenient for testing. Second, because the volume of the peripheral blood collection tube is small, the adapter should be equipped with measures to sense the peripheral blood collection tube so that the peripheral blood collection tube can be sensed in the detection instrument before testing.

[0004] In view of this, it is necessary to develop a test tube adapter suitable for immunoassay to solve the above problems. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a test tube adapter suitable for immunoassay, the structure of which is simple and effective, and can enable the peripheral blood collection tube to be located on the detection instrument for testing. The adapter is provided with positioning holes, which can be positioned and locked when the adapter is placed on the detection instrument. Moreover, an induction hole is provided at the lower end position of the adapter where the peripheral blood collection tube is located, so that the peripheral blood collection tube can be exposed for the detection instrument to sense the peripheral blood collection tube. To achieve the above object and other advantages of the present invention, a test tube adapter suitable for immunoassay is provided, including:

[0006] A support part for placing and supporting the peripheral blood vessel;

[0007] A clamping part integrally and fixedly connected to the lower part of the support part, and the clamping part is used to facilitate the clamp to clamp the peripheral blood vessel; and

[0008] A fixing part integrally and fixedly connected to the lower part of the clamping part at the end of the adapter, and the fixing part is used to fix and position the adapter,

[0009] Wherein, a positioning hole is provided on the side wall of the fixing part, and an induction hole is provided on the side wall opposite to the positioning hole.

[0010] Preferably, the adapter is an annular cylinder, and the diameter of the adapter is slightly larger than the diameter of the peripheral blood vessel.

[0011] Preferably, an arched hole is formed on the side wall below the induction hole.

[0012] Preferably, clamping positions are symmetrically arranged on both side walls of the clamping part.

[0013] Preferably, the depth of the clamping position is less than the radius of the adapter.

[0014] Preferably, the induction hole is a square hole, and the width of the induction hole is greater than the radius of the adapter.

[0015] Preferably, the distance from the upper boundary of the induction hole to the upper boundary of the support part is greater than the length of the peripheral blood vessel.

[0016] Preferably, a positioning member can be installed in the positioning hole, and the positioning member is used to lock and fix the adapter. The positioning member is preferably a top bead.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure is simple and effective, which can make the peripheral blood collection tube located on the detection instrument for detection. The adapter is provided with a positioning hole, which can be positioned and locked when the adapter is placed on the detection instrument.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. The foregoing and other objects, features, aspects, and advantages of the present invention will become more apparent, enabling those skilled in the art to implement it based on the description in the specification. In the drawings, for clarity, the shapes and dimensions may be enlarged, and the same reference numerals will be used throughout the figures to indicate the same or similar components. In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are based on the orientation or positional relationship shown in the drawings. In particular, "height" corresponds to the dimension from the top to the bottom, "width" corresponds to the dimension from the left to the right, and "depth" corresponds to the dimension from the front to the back. These relative terms are for convenience of description and generally do not intend to require a specific orientation. Terms related to attachment, connection, etc. (e.g., "connect" and "attach") refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as a movable or rigid attachment or relationship, unless otherwise explicitly stated.

[0024] Referring to Figures 1 - 5 , the test tube adapter suitable for immunoassay includes:

[0025] A support portion 31 for placing and supporting the peripheral blood vessel;

[0026] A clamping portion 32 integrally fixed below the support portion 31, and the clamping portion 32 is used to facilitate the clamping of the peripheral blood vessel by a clamp; and

[0027] A fixing portion 33 integrally fixed below the clamping portion 32 at the end of the adapter 3, and the fixing portion 33 is used to fix and position the adapter 3.

[0028] Referring to Figures 1 - 2 , a positioning hole 331 is provided on the side wall of the fixing portion 33, and an induction hole 333 is provided on the side wall opposite to the positioning hole 331. The induction hole 333 is used to sense the position of the peripheral blood vessel when the detection instrument detects the peripheral blood vessel, so as to perform the next operation on the peripheral blood vessel.

[0029] Referring to Figure 4 , the adapter 3 is a circular cylinder, and the diameter of the adapter 3 is slightly larger than the diameter of the peripheral blood vessel.

[0030] Furthermore, an arched hole 332 is provided on the side wall below the induction hole 333.

[0031] Referring to Figure 2, symmetrically arranged clamping positions 321 are provided on two side walls of the clamping part 32. When decapping the peripheral blood vessel again in the detection instrument, the clamp clamps the peripheral blood vessel in the adapter 3 through the clamping positions 321, so as to fix the peripheral blood vessel when decapping the peripheral blood vessel.

[0032] Furthermore, the depth of the clamping position 321 is less than the radius of the adapter 3.

[0033] Furthermore, the sensing hole 333 is a square hole, and the width of the sensing hole 333 is greater than the radius of the adapter 3.

[0034] Refer to Figure 3 , the distance from the upper boundary of the sensing hole 333 to the upper boundary of the support part 31 is greater than the length of the peripheral blood vessel. When the peripheral blood vessel is placed in the adapter 3, the peripheral blood vessel can be exposed in the sensing hole 333, and whether the peripheral blood vessel reaches the detection station can be sensed when on the detection table.

[0035] Furthermore, a positioning member can be installed in the positioning hole 331. The positioning member is used to lock and fix the adapter 3. The positioning member is preferably a top bead. The adapter 3 is used to place the peripheral blood vessel. Therefore, the adapter 3 needs to be fixed on the detection instrument. If it is not fixed, the adapter 3 is prone to rotate unstably during the detection process, causing certain problems and difficulties to the detection. Therefore, the adapter 3 can be automatically locked and fixed on the detection device through the positioning member in the positioning hole 331, and only the peripheral blood vessel needs to be clamped during the process of decapping the peripheral blood vessel.

[0036] During use, when detecting the peripheral blood vessel, first install and fix the adapter 3 on the detection device, and lock and fix it on the detection device through the top bead in the positioning hole 331. Then place the peripheral blood vessel in the adapter 3. At this time, the peripheral blood vessel extends to the position of the sensing hole 333, making the peripheral blood vessel exposed. At this time, the detection device can detect whether the peripheral blood vessel in the sensing hole 333 reaches the detection station through the sensor, and then perform the next operation on the peripheral blood vessel.

[0037] Although the embodiments of the present invention have been disclosed above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated and described examples here.
