An elisa kit for detecting a blood sample

Abstract

This utility model relates to the field of ELISA kit technology and discloses an ELISA kit for blood sample testing, including a box body. A sealing component is provided at the top of the box body, and a stabilizing component is fixedly connected to the inner wall of the box body. A slot is formed in the inner bottom wall of the box body, a groove is formed in the inner wall of the slot, a sliding groove is formed in the inner wall of the groove, and a slider is slidably connected to the inner wall of the sliding groove. This utility model allows test tubes to be inserted into several placement slots, ensuring even placement of the test tubes inside the box body, resulting in neater placement. The bottom of the test tube is inserted into the slot. Then, a micro-push rod is activated, which moves a magnetic block, causing the magnetic block to repel a clamping block. The clamping block moves into the slot due to the repulsion force, thus tightly clamping the outer wall of the test tube. This prevents the clamping force from decreasing over prolonged use, extending the lifespan of the device.

Description

Technical Field

[0001] This utility model relates to the field of ELISA kits, specifically an ELISA kit for blood sample testing. Background Technology

[0002] An ELISA kit is a detection tool that utilizes the specific binding of antigens and antibodies and the enzyme-catalyzed colorimetric reaction. ELISA kits for blood sample testing are in vitro detection tools designed based on the principle of enzyme-linked immunosorbent assay (ELISA). They are mainly used for the quantitative or qualitative analysis of specific biomarkers in blood (such as serum and plasma), such as antigens, antibodies, hormones, or cytokines. Existing ELISA kits for blood sample testing are not convenient for fixing the reagent tubes during use, which can easily cause shaking during the transfer of the ELISA kit, thus affecting the reagents.

[0003] To address the aforementioned issues, the ELISA kit for blood sample testing, published in Chinese Patent Publication No. CN212922470U, describes a method where reagent tubes containing reagents are inserted between clamping plates. The elasticity of the connecting post secures both sides of the reagent tubes. The lid is then closed. Rotating the threaded post causes the internal threaded cylinder to move the lifting plate downwards, further securing the reagent tubes from the top of the kit. A cooling system creates a low-temperature environment inside the kit, which helps preserve the reagents. Furthermore, the kit allows for securing the reagent tubes from different directions during rotation, improving stability and enhancing reagent preservation during transfer.

[0004] While the comparative patent solved the problem of inconvenience in fixing reagent tubes during use, which could cause shaking during ELISA kit transfer and affect the reagents, the device uses the elastic force of the elastic element to drive the clamping plate to hold the test tubes. However, the elastic element will lose elasticity due to fatigue after repeated use, which reduces the stability of the clamping of the test tubes and thus reduces the lifespan of the device.

[0005] Regarding the aforementioned related technologies, the device has the drawback of using the elastic force of the elastic element to drive the clamping plate to clamp the test tube. However, due to repeated use, the elastic element will become fatigued and lose its elasticity, thereby reducing the clamping stability of the test tube and thus reducing the service life of the device. Utility Model Content

[0006] Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an ELISA kit for blood sample testing. It features advantages such as the clamping force of the clamping block not decreasing with prolonged use, thus extending the device's lifespan. This solves the problem that the clamping plate, driven by the elastic force of the elastic element, clamps the test tube, but the elastic element weakens due to fatigue after repeated use, reducing the clamping stability and consequently shortening the device's lifespan.

[0008] (II) Technical Solution

[0009] To ensure that the clamping force of the aforementioned locking block does not decrease due to prolonged use, thereby extending the service life of the device, this utility model provides the following technical solution: an ELISA kit for blood sample testing, comprising a box body, a sealing component at the top of the box body, a stabilizing component fixedly connected to the inner wall of the box body, a locking groove on the inner bottom wall of the box body, a recess on the inner wall of the locking groove, a sliding groove on the inner wall of the recess, a slider slidably connected to the inner wall of the sliding groove, a locking block fixedly connected to one side of the slider, a spring fixedly connected to the bottom of the box body, a connecting plate fixedly connected to the bottom of the spring, and a control component at the top of the connecting plate.

[0010] As a preferred embodiment of this utility model, the sealing component includes a lid, a latch is provided on one side of the lid, and a handle is fixedly connected to the top of the lid.

[0011] As a preferred technical solution of this utility model, the stabilizing component includes a stabilizing plate, the outer wall of which is fixedly connected to the inner wall of the box, and a placement groove is provided on the top of the stabilizing plate.

[0012] As a preferred embodiment of this utility model, the card block has a spherical structure, one end of the card block extends into the interior of the card slot, the outer wall of the card block is slidably connected to the inner wall of the sliding groove, and the card block is a magnetic ball.

[0013] As a preferred technical solution of this utility model, the control component includes a miniature push rod fixedly connected to the top of the connecting plate, a magnetic block fixedly connected to the top of the miniature push rod, the magnetic block having a ring structure, a control groove being provided at the bottom of the box, and the magnetic blocks and the card blocks repelling each other.

[0014] In a preferred embodiment of this invention, the control groove is a circular ring structure, the magnetic block is in the same shape as the control groove, and the magnetic block is slidably connected to the inner wall of the control groove.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an ELISA kit for blood sample testing, which has the following beneficial effects:

[0017] 1. By inserting test tubes into several placement slots, the test tubes can be evenly inserted into the inside of the box, making the test tubes more neat. The bottom of the test tube is inserted into the slot. Then, the micro push rod is activated, which drives the magnetic block to move. This causes the magnetic block to repel the card block, and the card block will move into the slot due to the repulsion force. This allows it to tightly clamp the outer wall of the test tube, so that the clamping force will not decrease due to long-term use, thus extending the service life of the device.

[0018] 2. The sealing component includes a lid with a latch on one side and a handle fixedly connected to the top of the lid. The lid can seal the box, making it more convenient to carry. The lid can be fixedly installed on the top of the box with the latch, and the handle makes it easier to carry the box, further meeting the usage requirements of the device and thus improving its practicality.

The lid 2 can seal the box body 1, making it more convenient to carry. The lid 2 can be fixedly installed on the top of the box body 1 by the latch 3, and the handle 4 makes it more convenient to carry the box body 1.

[0028] Reference Figure 1-4 The stabilizing component includes a stabilizing plate 5, the outer wall of which is fixedly connected to the inner wall of the box 1.

[0029] Specifically, the card block 11 has a spherical structure, with one end of the card block 11 extending into the interior of the card slot 7. The outer wall of the card block 11 is slidably connected to the inner wall of the slide groove 9. The card block 11 is a magnetic ball. When one end of the card block 11 extends into the interior of the card slot 7, the bottom of the test tube is inserted into the interior of the card slot 7, and the card block 11 can clamp the test tube.

[0030] Reference Figure 1-4 The control component includes a miniature push rod 15 fixedly connected to the top of the connecting plate 14.

There are several placement slots 6, which can evenly insert the test tubes into the inside of the box 1, making the test tubes more neat. Insert the bottom of the test tube into the slot 7. Then activate the micro push rod 15. The micro push rod 15 will drive the magnetic block 16 to move, which will cause the magnetic block 16 to repel the card block 11. The card block 11 will move into the slot 7 due to the repulsion force, thus clamping the outer wall of the test tube tightly.
