Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of detection device, especially, relate to portable multi-index biological sample rapid detection integrated device. BACKGROUND

[0002] Portable multi-index biological sample rapid detection device shows important application value in many fields. In medical diagnosis, such equipment can realize rapid screening of key physiological indicators such as blood sugar, uric acid, cholesterol, lactic acid and inflammatory markers, thereby assisting early diagnosis of diseases and chronic disease management. In the field of environmental monitoring, portable detection devices can be used for water quality analysis, air pollutant detection and microbial pollution assessment. In addition, in food safety supervision, the technology can quickly detect pathogenic bacteria, pesticide residues and heavy metal content in food.

[0003] Currently, the operator usually needs to manually use a pipette or other adsorption device to drop the detection reagent onto the sample surface to ensure that the reagent can completely cover the sample to be tested and react with the sample. However, this method cannot accurately control the amount of detection reagent added each time, and individual differences can easily lead to inconsistent sample addition, affecting the accuracy and repeatability of the detection results. Secondly, the speed of manual operation is limited by the operator's proficiency, and long-term repetitive manual operation can easily cause operator fatigue and increase the risk of human error. In addition, manual operation also faces the problems of cross-contamination and reagent waste, which is not conducive to the standardization and automation development of the detection process.

[0004] Therefore, we provide a portable multi-index biological sample rapid detection integrated device to solve the above problems. INVENTION CONTENTS

[0005] To solve the above technical problems, the utility model is realized through the following technical schemes: the utility model is a portable multi-index biological sample rapid detection integrated device, which comprises a reagent cylinder for storing detection reagents, and the reagent cylinder is vertically arranged.

[0006] A detection chamber for storing cotton swabs is uniformly arranged in a circumferential array on the lateral surface of the reagent cylinder.

[0007] A plurality of flow tubes are arranged in a spiral downward and at equal intervals on the outer wall of the reagent cylinder, the two ends of the flow tube extend into the inner cavity of the reagent cylinder and the adjacent detection chamber respectively, and the end of the flow tube in the inner cavity of the reagent cylinder is sealed.

[0008] A cutting plate is rotatably arranged on the inner wall of the reagent cylinder, the flow tube is arranged on the rotation path of the cutting plate, and the cutting plate sequentially cuts the flow tubes arranged from top to bottom during rotation.

[0009] The present invention is further configured such that the test reagent inside the reagent cylinder flows sequentially from top to bottom through the flow tube and enters the test chamber, and the liquid level of the test reagent in the test chamber is above the cotton on the cotton swab.

[0010] The present invention is further configured such that a slit is provided at one end of the flow tube located in the inner cavity of the reagent cylinder along its circumferential side, the slit being isolated from the interior of the flow tube, and the slit being located on the rotation path of the cutting plate and facing the rotation direction of the cutting plate.

[0011] The present invention is further configured such that a test strip that can be observed from the outside is provided on the periphery of the detection chamber, and the test strip extends into the bottom of the detection chamber and directly contacts the test reagent mixed with the cotton swab.

[0012] The present invention is further configured such that a large gear is coaxially and rotatably disposed on the surface of the reagent cylinder, the large gear is fixedly connected to the cutting plate, and a small gear is rotatably disposed on the surface of the reagent cylinder to mesh with the large gear, the ratio of the number of teeth on the large gear to the number of flow tubes being equal to the number of flow tubes.

[0013] The present invention has the following beneficial effects: 1. The present invention sets up several flow tubes that are spirally distributed downward at equal intervals on the outer wall of the reagent cylinder. The distance between two adjacent flow tubes is the same, so the content of the detection reagent at the corresponding height inside the reagent cylinder is also the same. Therefore, the content of the detection reagent flowing from the flow tube to each detection chamber is also the same. Thus, by limiting the height of the flow tube, the equal amount of detection reagent can be automatically delivered.

[0014] 2. This utility model features a cutting plate that rotates inside the reagent cylinder. As the cutting plate rotates, it contacts and cuts the flow tubes from top to bottom, thus connecting the reagent cylinder to the inside of the detection chamber. This allows the test reagent to flow automatically into the detection chamber under gravity until the test reagent level is below the corresponding flow tube, thereby achieving automatic quantitative addition of the test reagent.

[0015] 3. The two ends of the flow tube of this utility model are set at different heights. The end located in the inner cavity of the reagent tube is higher than the end located in the inner cavity of the detection chamber, so as to prevent the detection reagent inside the detection chamber from flowing back into the reagent tube and contaminating the detection reagent inside the reagent tube.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Specific implementation

[0026] Please refer to Figure 1 , Figure 4 The present application is a portable multi-index biological sample rapid detection integrated device, which comprises a reagent cylinder 1 capable of storing detection reagents, and the reagent cylinder 1 is vertically arranged; a detection bin 2 capable of storing cotton swabs, and the detection bin 2 is uniformly arranged in a circumferential array on the side surface of the reagent cylinder 1.

[0027] Specifically, the detection bin 2 is provided with multiple groups, one cotton swab is placed in each detection bin 2, and one end of the cotton swab with cotton is downwardly inserted into the inside of the detection bin 2.

[0028] Specifically, please refer to Figure 1 , Figure 2 ​Also comprising several flow tubes 3 spirally downward and equally spaced on the outer wall of the reagent cylinder 1. In the horizontal direction, the distance between two adjacent flow tubes 3 is the same, and in the vertical direction, the distance between two adjacent flow tubes 3 is also the same. Therefore, the content of the detection reagent at the corresponding height inside the reagent cylinder 1 is the same, and the content of the detection reagent flowing from the flow tube 3 into each detection chamber 2 is also the same. Therefore, the height of the flow tube 3 can be automatically limited to achieve equal delivery of the detection reagent.

[0037] Further, the detection reagent in the reagent cylinder 1 flows from top to bottom through the flow pipes 3 and enters the inside of the detection chambers 2, and the liquid level of the detection reagent in the detection chambers 2 is above the cotton on the cotton swab;

[0038] Specifically, the detection reagent covers the cotton, so that all the components on the cotton can contact with the detection reagent, and the detection accuracy is improved.

[0039] Further, please refer to Figure 4 The detection chamber 2 is provided with a detection test paper 6 which can be observed from the outside, the detection test paper 6 extends into the bottom of the detection chamber 2 and directly contacts with the detection reagent mixed with the cotton swab;
