Description

Technical Field

[0001] This invention belongs to the field of in vitro diagnostic reagent technology, specifically a novel self-testing 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, appliances, 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. Blood collection testing devices are a common type of in vitro diagnostic reagent.

[0003] However, existing blood collection and testing devices are mostly used in laboratory testing. The assembly process is relatively complicated, with many accessories, making them inconvenient to use and not portable. At the same time, existing blood collection and testing devices mostly use swabs to drop samples onto test strips or swabs onto test plates. Direct testing between test plates and test strips results in extremely poor sealing. Most test samples contain a large number of infectious viruses or bacteria, causing great environmental pollution. Furthermore, during the testing process, the samples are in prolonged contact with air, which 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 type of self-testing blood collection and detection device.

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

[0006] A novel self-testing blood collection device includes a collection mechanism, a cannula, and a buffer container. The collection mechanism includes a test strip housing, a blood collection head is attached to the bottom of the test strip housing, a test strip is disposed inside the test strip housing, and the bottom end of the test strip is inserted into the upper end of the blood collection head.

[0007] Preferably, the test strip housing and the blood collection head are connected by an interference fit with a perforated column.

[0008] Preferably, the buffer solution container is pre-filled with buffer solution, and the top of the buffer solution container is sealed with aluminum foil.

[0009] Preferably, the buffer solution container has a frustum-shaped structure, and the sleeve has a cylindrical structure. Its bottom is threaded to the top of the buffer solution container and sealed by a sealing ring at the step of the buffer solution container.

[0010] Preferably, the collection mechanism is slidably connected to the upper end of the sleeve and sealed by a sealing ring fitted at the lower end of the test paper housing.

[0011] Preferably, the test paper housing has an exhaust port.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] In this invention, the product has a simple structure, is easy to assemble, carry, and use, and can achieve a relatively sealed blood collection and testing process, reducing environmental pollution caused by sample contact with the environment and errors in test results, thereby improving the accuracy of test results.

[0021] The following is in conjunction with the appendix Figure 1-6 This invention further illustrates the specific implementation of a novel self-testing blood collection and testing device. The novel self-testing blood collection and testing device of this invention is not limited to the descriptions in the following embodiments.

[0022] Example 1:

[0023] This embodiment provides a specific implementation method for a novel self-testing blood collection and detection device, such as... Figure 1-4As shown, it includes a collection mechanism 1, a cannula 2, and a buffer container 3. The collection mechanism 1 includes a test strip housing 11, a blood collection head 12 is attached to the bottom of the test strip housing 11, and a test strip 13 is provided inside the test strip housing 11. The bottom end of the test strip 13 is inserted into the upper end of the blood collection head 12. The structure is simpler, easier to assemble, easier to carry, and easier to use.

[0024] Furthermore, the test strip housing 11 and the blood collection head 12 are connected by an interference fit with a perforated column.

[0025] Furthermore, the buffer solution container 3 is pre-filled with buffer solution, and the top of the buffer solution container 3 is sealed with aluminum foil.

[0026] Furthermore, the test strip housing 11 has an exhaust hole 14, which facilitates liquid climbing.

[0027] Furthermore, the test strip 13 is a colloidal gold immunochromatographic test strip, which includes a sample pad, a gold label pad, a nitrocellulose membrane, and an absorbent pad along the chromatography direction.

[0028] Furthermore, the test strip casing 11 is made of a transparent material.

[0029] Working principle: such as Figure 1-4 As shown, firstly, the collection mechanism 1 is a pre-assembled structure. Hold the test strip housing 11 and insert the blood collection head 12 into the blood test tube. Blood enters the blood collection head 12 through the through hole below the blood collection head 12. Press the vent hole 14 at the top of the test strip housing 11 and take out the blood collection head 12. At this time, the collection mechanism 1 is in a sealed state and the blood will not flow out. The blood collection process is completed.

[0030] Example 2:

[0031] This embodiment provides a specific implementation method for a novel self-testing blood collection and detection device, such as... Figure 1-4 As shown, the other structures are similar to those in Example 1. Furthermore, the lower end of the blood collection head 12 is a needle-like structure.

[0032] Working principle: such as Figure 1-4 As shown, firstly, the collection mechanism 1 is a pre-assembled structure. Hold the test strip housing 11 and pierce the skin with the needle-like structure at the bottom of the blood collection head 12. Blood enters the blood collection head 12 through the through hole below the blood collection head 12. Press the vent hole 14 at the top of the test strip housing 11 and pick up the blood collection head 12. At this time, the collection mechanism 1 is in a sealed state and the blood will not flow out. The blood collection process is completed.

Figure 5-6As shown, other structures are similar to those in Embodiment 1 or 2. Furthermore, the buffer container 3 adopts a frustum-shaped structure, and the sleeve 2 adopts a cylindrical structure. Its bottom is threaded to the top of the buffer container 3 and sealed by a sealing ring at the step of the buffer container 3.

[0035] Furthermore, the collection mechanism 1 is slidably connected to the upper end of the sleeve 2 and sealed by the sealing ring fitted at the lower end of the test paper housing 11.

[0036] Working principle: such as Figure 5-6 As shown, first, screw the lower end of the cannula 2 onto the upper end of the buffer solution container 3, press the vent 14 at the upper end of the test strip housing 11, and pass the lower end of the blood collection head 12 through the upper end of the cannula 2 until the outer end of the test strip housing 11 slides and seals with the upper end of the cannula 2. At this time, the lower end of the blood collection head 12 punctures the aluminum foil at the top of the buffer solution container 3. Release the vent 14 at the upper end of the test strip housing 11 and fully insert the blood collection head 12 into the buffer solution container 3. After a period of time, observe the state of the test strip through the test strip housing 11, record the test results, and the test process is complete.
