Description

Technical Field

[0001] This invention relates to the field of medical testing technology, specifically to testing kits, and more particularly to an integrated multi-channel testing kit. Background Technology

[0002] A test kit is a tool used for the quantitative or qualitative detection of specific chemical substances, biomolecules, or pathogens in a sample. It has wide applications in fields such as medical diagnostics, food safety, environmental monitoring, and biological research. It typically contains a test strip. The sample is added to one end of the strip, and then, through capillary action, the sample moves gradually along the strip, reacting with pre-set reagents. The result is determined by the color change at the marked area on the test strip.

[0003] Conventional testing kits contain only a single test strip and are used for a single test. For patients with complications, such as diabetes who may also have hyperglycemia, diabetic nephropathy, or ketoacidosis; and patients with metabolic syndrome who are at higher risk and may also have hyperglycemia, hyperlipidemia, hypertension, or hyperuricemia, screening each condition individually is inefficient.

[0004] Utility model patent CN221976885U discloses a pen-tube type multi-channel test kit. The kit has an overall cylindrical structure with multiple sample slots arranged in a ring and each slot containing an independently configured test strip, overcoming the problem of uneven sample absorption in a row of test strips. However, because multiple sample slots evenly distribute the sample within the lower cover, different test strips exhibit varying capillary action; strips with stronger capillary action absorb more sample, failing to effectively solve this problem. Furthermore, this structure requires the slots to be compatible with the test strips, necessitating trimming or batch processing of test strips of different specifications. However, whether trimming affects test strip performance remains questionable. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. Firstly, it provides an integrated multi-channel detection kit that enables even sample distribution across different test strips. Secondly, it addresses the issue of the need for cutting and post-processing test strips in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution. An integrated multi-channel detection kit includes a cylindrical body, the top surface of which is detachably provided with a cap, and the bottom surface of which is provided with a thin wall; at least two detection chambers are evenly distributed around the outer periphery of the cylindrical body, and a sample chamber is formed within each detection chamber; a dispensing component is provided at the lower part of the cylindrical body, the dispensing component including a puncture part directly opposite the center of the thin wall, the puncture part being connected to the bottom of the sample chamber via a dispensing chamber formed radially along the cylindrical body, and a slot for connecting test strips is provided at the bottom inner side of the sample chamber.

[0007] As a preferred technical solution, a capillary plate with a horizontally opened sample groove is inserted into the slot, and the sample groove has a through-groove structure.

[0008] As a preferred technical solution, the top surface of the cover is provided with a corrugated grip, and the bottom surface of the cover extends into the inner side of the cylinder with a sampling spoon.

[0009] As a preferred technical solution, the top of the cylinder is provided with rotating plates evenly distributed radially outward, and the inner side of the top of the testing chamber is provided with a connecting groove adapted to the rotating plates.

[0010] As a preferred technical solution, an opening is left between adjacent testing chambers, which allows the swivel tab to slide along the cylinder axis within it.

[0011] As a preferred technical solution, the liquid separation component is also provided with a conical transition surface adapted to the diameter of the cylinder.

[0012] As a preferred technical solution, the liquid separation chamber is inclined downwards from the center of the bottom surface of the cylinder.

[0013] As a preferred technical solution, a flow guiding funnel is provided inside the cylinder.

[0014] As a preferred technical solution, the cover is provided with a convex ring in the circumferential direction, and the convex ring is interference-fitted with the cylinder.

[0015] As a preferred technical solution, the bottom surface of the detection chamber and the liquid separation component is provided with a bottom cover, and the slot is provided on the bottom cover.

[0016] As a preferred technical solution, the testing chamber is made of a transparent material, such as polycarbonate.

[0017] As a preferred technical solution, the cover is also provided with a stop that can abut against the connection between the swivel plate and the cylinder.

[0018] The advantages and beneficial effects of this invention are as follows: through the interaction between the dispensing component and the dispensing chamber, the sample can be evenly distributed radially from the central puncture point to each detection chamber. The puncture part directly punctures the thin wall of the sample container, avoiding the risk of contamination from manual opening, while the dispensing chamber tilts downward to guide the sample evenly into each detection chamber using gravity, reducing residue.

Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-5 This embodiment provides an integrated multi-channel detection kit, including a cylindrical body 1 and a cap 2. The top of the cylindrical body 1 is detachably sealed to the cap 2 via an interference fit. The cap 2 has a raised ring 16 around its periphery, which is interference-fitted with the cylindrical body 1 to prevent contamination from manual opening. Three detection chambers 4 are evenly distributed around the outer periphery of the cylindrical body 1, and each detection chamber 4 contains a sample chamber 5. The top surface of the cap 2 is designed with a corrugated grip 9 for easy operation; when opening the cap, only the grip 9 is in contact, reducing the risk of contamination.

[0022] The lower part of the cylinder 1 is provided with a liquid separation component, which is directly opposite the center of the thin wall 3 at the bottom of the cylinder through the puncture part 6, and the sample is diverted to the bottom of the sample chamber 5 in each detection chamber 4 through the radial liquid separation chamber 19. The liquid separation chamber 19 extends radially outward from the center of the bottom surface of the cylinder and is inclined downward. A flow guide funnel 15 is provided inside the cylinder 1 to guide the sample to flow evenly by gravity.

[0023] The sample chamber 5 has a slot 7 at its bottom inner side. A capillary plate 8 with a horizontally oriented sample groove 18 is inserted into the slot 7. The sample groove 18 has a through-groove structure with a width of more than 8 cm. Different test strips can be attached to the sample groove 18 with double-sided tape. The double-sided tape should be placed at the top of the test strip as much as possible and should be avoided on the marked reagent area of ​​the test strip.

[0024] Example 2 This embodiment provides an integrated multi-channel detection kit. The difference from Embodiment 1 is that three screw-on tabs 11 are evenly distributed radially outward on the top of the cylinder 1. A sampling spoon 10 is provided on the bottom of the cover 2 extending towards the inner side of the cylinder, and a corrugated grip 9 is provided on the top surface to facilitate operation and reduce the risk of contamination. The cover 1 is also provided with a stop block 20 that can abut against the connection between the screw-on tabs 11 and the cylinder 1.

[0025] The inner top of the detection chamber 4 is provided with a connecting groove 12 for the adapter screw plate 11. An opening 13 is left between adjacent detection chambers, allowing the screw plate 11 to slide along the axial direction of the cylinder 1, so as to achieve uniform distribution and stable connection of the detection chambers. The liquid dispensing chamber 19 is inclined downward from the center of the cylinder. Under normal conditions, the screw plate 11 is locked in the connecting groove 12. When in use, the connection between the screw plate 11 and the connecting groove 12 is unlocked, the screw plate 11 is aligned with the opening 13, and the cover 2 is pressed to drive the cylinder 1, so that the piercing part 6 of the liquid dispensing component directly pierces the thin wall 3. The sample flows evenly into each detection chamber 4 through the piercing part and the liquid dispensing chamber 19.

[0026] Example 3 This embodiment provides an integrated multi-channel detection kit. The difference from embodiment 2 is that the dispensing component is provided with a conical transition surface 14 that is adapted to the diameter of the cylinder 1. When the cylinder 1 is pressed down, it aligns with the puncture part 6 and smoothly dispenses the sample to each detection chamber 4.

[0027] The bottom surface of the detection chamber 4 and the dispensing component is provided with a bottom cover 17, and the slot 7 is directly opened on the bottom cover, which simplifies the structure and facilitates manufacturing. The bottom cover is integrally connected to the dispensing component or the detection chamber 4 by welding or gluing, which improves the sealing performance of the detection box. The cover body 2 is provided with a convex ring 16 that is interference-fitted with the cylinder body 1 around its circumference, which improves the sealing effect of sample transfer.

[0028] Example 4 This embodiment provides an integrated multi-channel detection kit with five detection chambers 4 evenly distributed around its outer perimeter. Each detection chamber contains a sample chamber 5 and a slot 7. The dispensing chamber is radially inclined outward from the center of the bottom surface of the cylinder, and combined with the guide funnel 15 and the conical transition surface 14, it ensures that the sample is evenly distributed to each detection chamber 4. A transverse through-groove capillary plate 8 is installed in the slot 7, and the sampling spoon 10 extending from the bottom surface of the cover 2 facilitates accurate sampling. The screw-on tab 11 and the connecting groove 12 achieve a stable connection between the detection chambers.

[0029] Example 5 An integrated multi-channel test kit differs from Example 4 in that the test strip replaces the capillary plate 8 and is directly placed on the slot 7.

[0030] The working principle of this invention is as follows: During the production process of this reagent kit, the test strip is inserted into the slot 7 at the bottom of the detection chamber. If a capillary plate 8 is used, the test strip needs to be attached to the surface of the transverse through-slot sample slot 18, ensuring that the sample contact end of the test strip is close to the outlet of the dispensing chamber 19 so that the sample can flow through capillary action. The reagent kit adopts a screw-on tab 11 and a connecting groove 12 structure. The detection chamber 4 is slid along the opening 13 at the top of the cylinder 1 to the designated position, and the detection chamber 4 is fixed by the engagement of the screw-on tab 11 and the connecting groove 12.

[0031] In the embodiment with the stop 20, when sampling, press the cover 2 so that the stop 20 and the swivel piece 11 of the cover 2 abut against each other. Rotate the cover 2 counterclockwise from a top view. The cover 2 will drive the cylinder 1 to rotate together, so that the swivel piece 11 will disengage from the connecting groove 12 and reach the opening 13, thus completing the unlocking.

[0032] For embodiments with a bottom cover 17, the bottom cover is aligned and sealed with the detection chamber 4 and the dispensing component. During sample collection, the cover 2 is removed, and the sampling spoon 10 at its bottom is used to accurately collect the liquid sample. After sampling, the cover is replaced and sealed again with the cylinder 1. The dispensing tab 11 is loosened, and the cylinder 1 is pressed down so that the puncture part 6 pierces the bottom thin wall 3. The sample enters the dispensing chamber 19 through the puncture point. After slowly flowing into the sample chamber 5, the sample is evenly distributed onto the test strip through the transverse groove sample slot 18 of the capillary plate 8.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
