Description

Technical Field

[0001] This utility model relates to the field of rapid detection technology, and more specifically, to a portable rapid detection reagent card. Background Technology

[0002] In the fields of medical diagnostics, food safety, and environmental monitoring, rapid test kits are widely used due to their ease of use and immediate results. Traditional test kits typically consist of a casing, a test strip, and a sampling component, but they suffer from the following technical limitations:

[0003] Sealing issues: Existing products mostly use simple caps or thin film packaging, which are easily subjected to external pressure during transportation and storage, leading to seal failure.

[0004] 1. Contamination Risk: Sampling heads exposed to the elements are easily contaminated with environmental pollutants, especially when used outdoors, where airborne dust or microorganisms can easily contaminate the testing site. A recall of a certain brand of HIV test strips was due to increased false positive rates caused by contamination of the sampling heads during transportation.

[0005] 2. Poor ease of use: The existing sealing structure requires users to perform multiple steps such as tearing the film and rotating to unlock, which demands a high level of technical skill from the operator. In the event of a public health emergency, non-professionals are prone to operational errors when using it.

[0006] To address the aforementioned issues, the industry has attempted various solutions, such as using vacuum aluminum foil packaging (increasing costs by 30%) and adding secondary sealing rings (leading to structural complexity). However, none of these solutions have solved the fundamental problem while ensuring economic efficiency. Therefore, there is an urgent need to develop a new type of test card structure that combines reliable sealing, contamination prevention, and ease of operation. Utility Model Content

[0007] Based on the above-mentioned technical problems, this utility model proposes a portable rapid test reagent card.

[0008] A portable rapid test kit includes a card body, which consists of an outer shell, a test paper, and a sampling head. The test paper is placed inside the outer shell, and the sampling head is located at the front end of the card body. The rear end of the sampling head is connected to the test paper. The front end of the card body is provided with a sealing head, which is open at the front end and closed at the rear end, and the sealing head encloses and seals the sampling head. A groove is provided at the connection between the rear end of the sampling head and the front end of the card body. The front end of the sealing head is provided with a connector, which can be inserted into the groove to seal the sampling head.

[0009] Preferably, the slot is a trapezoidal slot with an opening width greater than the width of the slot bottom, and the connector is a trapezoidal ring rib that matches the slot.

[0010] Preferably, the front end of the connector is provided with a sealing ring, the width of which is greater than the bottom width of the slot.

[0011] Preferably, the sealing ring is made of a flexible material.

[0012] Preferably, the sampling head has a connecting part at its rear end, which extends outward from the middle of the slot. The size of the connecting part is larger than the size of the sampling head, and the connecting part fits tightly with the inner wall of the end cap.

[0013] Preferably, the bottom of the connector has a protruding side rib, and a side groove is opened on the side wall at the opening of the slot. After the connector is inserted into the slot, the side rib is inserted into the side groove.

[0014] Beneficial effects:

[0015] 1. Multiple sealing protection: The triple sealing structure of physical wrapping + mechanical clamping + elastic compensation ensures that the product remains intact and sealed even under extreme transportation conditions;

[0016] 2. Improved anti-contamination performance: The closed-type sampling head storage reduces the probability of microbial contamination;

[0017] 3. Ease of operation: The plug-in opening design allows for easy exposure of the sampling head with one hand, reducing operation time;

[0018] 4. Connection reliability: The combination design of trapezoidal slots and reinforced connection parts enables the structure's vibration resistance performance to meet the requirements of MIL-STD-810G standard. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] like Figures 1-4The portable rapid test kit shown includes a kit body 1, which consists of a shell 101, a test paper, and a sampling head 103. The test paper is placed inside the shell 101, and the sampling head 103 is located at the front end of the kit body 1. The rear end of the sampling head 103 is connected to the test paper.

[0025] The front end of the card body 1 is provided with a cap 2, which is open at the front end and closed at the rear end. The cap 2 encloses and seals the sampling head 103, effectively preventing the sampling head 103 from being contaminated by the outside world during storage and transportation. A groove 104 is provided at the connection between the rear end of the sampling head 103 and the front end of the card body 1. The front end of the cap 2 is provided with a connector 201, which can be inserted into the groove 104 to seal the sampling head 103, ensuring the stability of the reagent and the accuracy of the detection.

[0026] As a further improvement, the slot 104 is a trapezoidal slot, and the width of its opening 202 is greater than the width of the bottom of the slot. The connector 201 is provided with a trapezoidal ring rib that matches the slot 104, which facilitates the insertion and fixing of the connector 201.

[0027] The front end of the connector 201 is provided with a sealing ring. The width of the sealing ring is greater than the bottom width of the slot 104 to enhance the sealing effect. The sealing ring is made of flexible material to improve the fit with the slot 104.

[0028] The sampling head 103 has a connecting part 102 at its rear end. The connecting part 102 extends outward from the middle of the slot 104. The size of the connecting part 102 is larger than the size of the sampling head 103. The connecting part 102 fits tightly with the inner wall of the end cap 2 to further enhance sealing and protection.

[0029] The bottom of the connector 201 is provided with a protruding side rib 203, and a side groove is opened on the side wall at the opening 202 of the slot 104. After the connector 201 is inserted into the slot 104, the side rib 203 is inserted into the side groove, which enhances the fixing effect of the connector 201 in the slot 104 and prevents it from falling off.
