Description

Technical Field

[0001] This invention belongs to the field of in vitro diagnostic reagent technology, specifically a novel blood collection and testing device. Background Technology

[0002] In vitro diagnostic reagents refer to in vitro diagnostic reagents managed as medical devices. These include reagents, kits, calibrators, and quality control materials that can be used alone or in combination with instruments, apparatus, equipment, or systems for in vitro testing of human samples (various body fluids, cells, tissue samples, etc.) in the processes of disease prevention, diagnosis, treatment monitoring, prognosis observation, health status evaluation, and prediction of hereditary diseases. Sample collection and testing devices (such as blood and urine samples) are a common type of in vitro diagnostic reagent.

[0003] Most current sample collection and testing devices are operated manually. They typically involve dropping samples onto test strips using a collection swab or onto a test plate using a collection swab. However, direct testing between the test plate and the test strip results in extremely poor sealing. Most samples contain a large number of infectious viruses or bacteria, causing significant environmental pollution. Furthermore, the long-term contact between the sample and the air during the testing process can easily lead to errors in the test results. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new blood collection and testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel blood collection and testing device includes a detection cylinder and a stopper for detection, a collector and a blood collection head for collection. The blood collection head includes a cover section, a neck section and a tip section arranged sequentially from top to bottom. A shell is fitted over the outside of the tip section. The shell is fixed to the upper end of the tip section by a snap-fit ​​structure. The shell has an opening, and a cavity is formed between the tip section and the shell.

[0007] Preferably, the collector includes a main tube with an easy-tear aluminum foil at the upper opening and a bottom aluminum foil at the lower opening, and a pre-packaged buffer solution inside.

[0008] Preferably, the main tube is a transparent injection molded part, and the easy-tear aluminum foil and the bottom aluminum foil are respectively hot-sealed to the upper and lower ends of the main tube.

[0009] Preferably, after tearing off the easy-tear aluminum foil, the blood collection head is inserted into the upper end of the main tube, and the blood in the lower cavity of the blood collection head is mixed with the buffer solution. The neck segment is sealed to the inner wall of the upper end of the main tube.

[0010] Preferably, the bottom of the detection cylinder is provided with a piercing structure for piercing the bottom aluminum foil, and one side of the piercing structure is a jamming area.

[0011] Preferably, the plug includes a detection section and a sleeve section above it. The detection section is inserted into the plug area, and a plurality of test strips are provided on the side of the detection section away from the puncture structure. The sleeve section is fitted onto the opening of the detection cylinder.

[0012] Preferably, the test strip is a colloidal gold immunochromatographic test strip, the test tube adopts a transparent injection-molded structure, and the sleeve section is sealed and fitted onto the opening of the test tube.

[0013] Preferably, it also includes a pressing handle for pressing the collector into the detection cylinder. The piercing structure at the bottom of the detection cylinder pierces the aluminum foil at the bottom of the collector, and the solution inside the collector flows out to the bottom of the detection cylinder to contact the test strip for detection.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] In this invention, after blood is collected by the blood collection head, it is directly inserted into the sample collector for mixing. The blood collection head is directly sealed with the sample collector. Then, the sample collector is inserted into the detection device for detection. The aluminum foil at the bottom of the sample collector is punctured by the puncture structure, and the liquid inside the sample collector flows out to the bottom of the reagent kit and comes into contact with the test strip for detection. This reduces the time the sample is exposed to the air, reduces environmental pollution and the spread of viruses, and improves the accuracy of the test results. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-9 This invention further illustrates the specific implementation of a novel blood collection and testing device. The novel blood collection and testing device of this invention is not limited to the descriptions in the following embodiments.

[0027] Example 1:

[0028] This embodiment provides a specific implementation method for a novel blood collection and testing device, such as... Figure 1-9 As shown, it includes a detection cylinder 1 and a stopper 2 for detection, a collector 3 and a blood collection head 5 for collection. The blood collection head 5 includes a cover section 51, a neck section 52 and a tip section 53 arranged sequentially from top to bottom. A shell 54 is fitted on the outside of the tip section 53. The shell 54 is fixed to the upper end of the tip section 53 by a snap-fit ​​structure. The shell 54 has an opening, and a cavity is formed between the tip section 53 and the shell 54.

[0029] Furthermore, the outer side of the cover section 51 adopts an injection-molded overmolded structure, which works with the plug 2 to provide a sealing function, and the outer side of the neck section 52 works with the main tube 31 to provide a sealing function through a silicone O-ring or an injection-molded overmolded structure.

[0030] Furthermore, the collector 3 includes a main tube 31, with an easy-tear aluminum foil 32 at the upper opening and a bottom aluminum foil 33 at the lower opening, which is pre-packaged with buffer solution.

[0031] Furthermore, the main tube 31 is a transparent injection molded part, and easy-tear aluminum foil 32 and bottom aluminum foil 33 are respectively hot-sealed to the upper and lower ends of the main tube 31.

[0032] Furthermore, the bottom of the detection cylinder 1 is provided with a piercing structure 11 for piercing the bottom aluminum foil 33, and one side of the piercing structure 11 is a jamming area 12.

[0033] Furthermore, the jammer 2 includes a detection section 21 and a sleeve section 22 above it. The detection section 21 is inserted into the jammer area 12. Several test strips 23 are provided on the side of the detection section 21 away from the puncture structure 11. The sleeve section 22 is fitted onto the opening of the detection cylinder 1.

[0034] Furthermore, the test strip 23 is a colloidal gold immunochromatographic test strip, the test tube 1 adopts a transparent injection molded structure, and the sleeve section 22 is sealed and fitted onto the opening of the test tube 1.

[0035] Working principle: such as Figure 1-8 As shown, firstly, the blood is drawn into the cavity formed between the tip 53 of the blood collection head 5 and the shell 54 (capillary action). After tearing off the easy-tear aluminum foil 32 at the top of the main tube 31, the blood collection head 5 with collected blood is inserted into the main tube 31, so that the blood and buffer solution come into contact and mix. At this time, the blood in the lower cavity of the blood collection head 5 is mixed with the buffer solution, and the neck 52 is sealed to the upper inner wall of the main tube 31.

[0036] Example 2:

[0037] This embodiment provides a specific implementation method for a novel blood collection and testing device, such as... Figure 1-9 As shown, the other structures are similar to those in Example 1. Furthermore, after tearing off the easy-tear aluminum foil 32, the blood collection head 5 is inserted into the upper end of the main tube 31. The blood in the lower cavity of the blood collection head 5 is mixed with the buffer solution, and the neck segment 52 is sealed to the inner wall of the upper end of the main tube 31.

[0038] Furthermore, it also includes a pressing handle 4, which is used to press the collector 3 into the detection cylinder 1. The piercing structure 11 at the bottom of the detection cylinder 1 pierces the aluminum foil 33 at the bottom of the collector 3, and the solution inside the collector 3 flows out to the bottom of the detection cylinder 1 to contact the test paper 23 for detection.

[0039] Furthermore, the collector 3 is inserted into the sleeve section 22 and slides to the bottom of the detection cylinder 1 by pressing the handle 4, until the piercing structure 11 pierces the aluminum foil layer 35.

[0040] Furthermore, the outer side of the sleeve section 22 is made of soft rubber injection molding to seal the plug 2 and the detection cylinder 1.

[0041] Furthermore, the test strip 23 includes a colloidal gold immunochromatographic test strip disposed at the upper end of the detection section 21, and a coverslip staining device disposed at the lower end of the detection section 21. The coverslip staining device includes a glass slide, a nitrocellulose membrane, and a coverslip arranged in sequence, and a staining pad is provided at its liquid inlet end. The staining pad is made of absorbent material and is used to absorb cells in the liquid sample and stain them. The colloidal gold immunochromatographic test strip includes a sample pad, a gold label pad, a nitrocellulose membrane, and an absorbent pad along the chromatography direction.

[0042] Furthermore, the stopper 2 is sealed to the detection cylinder 1; the collector 3 is sealed to the stopper 2.

[0043] Working principle: such as Figure 9As shown, insert the blood sample collector 3, containing diluted and mixed blood, into the testing box (test tube 1 + stopper 2) – it needs to be inserted to the bottom of the testing box to ensure overall sealing. (This can be done manually by pressing the handle 4 with an external tool, or with the accompanying equipment).

[0044] The puncture structure at the bottom of the detection cartridge 1 punctures the aluminum foil at the bottom of the collector 3, allowing the blood sample to remain at the bottom of the detection box. The colloidal gold immunochromatographic strip absorbs the sample for performance testing. The carrier wave staining device absorbs the sample, stains the cells in the blood, and allows for observation using microscopic equipment.
