Description

Technical Field

[0001] The utility model relates to the technical field of in-vitro sample detection devices, in particular to a portable liquid sample concealed detection device. Background Art

[0002] At present, common high-precision detection methods for liquid samples include gas chromatography (GC), high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-tandem mass spectrometry (LC-MS / MS), etc. However, the above methods rely on large instruments, have a long detection time, and are complex to operate and require professional technicians, which are not suitable for large-scale and rapid on-site detection.

[0003] Immunoassay is an analytical method that uses the specific binding reaction of antigen and antibody to detect various substances, and uses the principle of immune binding reaction to detect whether the analyte exists in the sample. Among them, the rapid detection of liquid samples has been widely used in the field of in-vitro diagnosis, such as drug abuse. However, the existing rapid detection products for liquid samples are large in volume, need to place the product at a specific position or use quantitative transfer instruments such as pipettes to add samples during the operation process, and have certain requirements for the use environment, which do not meet the needs of concealed detection. With the continuous emergence of new synthetic drugs, such drugs may often be used by criminals in public entertainment places or the food industry chain, becoming substitutes for traditional drugs or illegal food additives. To detect whether prohibited drugs are added to liquid samples such as beverages and are not easily detected by criminals, higher requirements are put forward for the portability, concealment, and functionality of existing detection devices. Summary of the Invention

[0004] In order to solve the technical problems in the prior art that the liquid sample sampling and detection device is large in volume, not conducive to hiding, has numerous operation steps, and has special requirements for the use environment, the utility model provides a portable liquid sample concealed detection device. By combining the liquid sample concealed detection device with a traditional electronic watch, the technical effects of reducing the volume of the detection device, being convenient for hiding, simplifying the operation steps, and reducing the requirements for the surrounding environment are achieved.

[0005] The specific technical solution of the utility model is as follows:

[0006] A portable liquid sample concealed detection device, comprising:

[0007] A fixed housing;

[0008] A bracelet band connected to both ends of the fixed housing;

[0009] A time display component installed on the housing cover;

[0010] The detection component is installed inside the fixed housing. The detection component includes a sampling hole filler and a reagent strip fixed on one side of the fixed housing. The reagent strip is provided with a detection marking line and a quality control marking line. A time display component is installed on the lid. The reagent strip also contains a sample pad installed at the bottom of the reagent strip, and the sample pad is located below the sampling hole filler. A lid detachably connected to the fixed housing, the lid is provided with a sampling hole corresponding to the sampling hole filler, a detection display window corresponding to the detection marking line, and a quality control display window corresponding to the quality control marking line.

[0011] The detection component for detecting liquid samples is arranged inside the fixed housing. The fixed housing is connected to the detachable lid. At the same time, a time display component is also installed on the lid, so that the detection component is located inside the whole device and cannot be directly observed from the outside, achieving the purpose of hiding the device. At the same time, the detection component is composed of a sampling hole filler and a reagent strip. When the operator uses it, the collected liquid sample is added from the sampling hole and infiltrates into the sampling hole filler below, and then slowly enters the sample pad for running the plate. After completion, the operator can directly observe the detection line display window and the quality control line display window for observation and comparison to draw a conclusion. This operation process simplifies the previous operation steps and has no requirements for the surrounding operation environment, is convenient to carry, and is convenient for detecting at any time, making improvements for detecting operations required in special situations.

[0012] Preferably, the lid is connected to the fixed housing through a hinge, which is convenient for observing the progress of the plate running in a timely manner during the operation process.

[0013] Preferably, a reagent strip insertion board is installed on the fixed housing, and the reagent strip can be fixed in the fixed housing through the corresponding size reagent strip insertion board and the card slot, which is convenient for accurately observing through the quality control detection window and the detection display window on the outside of the lid.

[0014] Preferably, the reagent strip insertion board can be made of injection molded sheet material.

[0015] Preferably, the reagent strip insertion board can be a single reagent strip insertion board, a two-in-one reagent strip insertion board, a three-in-one reagent strip insertion board, a four-in-one reagent strip insertion board or a five-in-one reagent strip insertion board.

[0016] Preferably, the detection display window and the quality control display window are covered with a translucent material to facilitate hiding the internal reagent strip.

[0017] The time display component includes at least one display module and a function knob installed on the lid. Setting the time display component on the lid can disguise the detection device inside the fixed housing to achieve the technical effect of hiding.

[0018] The function knob is signal-connected to the display module, and the switch of the display module is controlled by controlling the function knob, which saves resources and is convenient for checking messages in a timely manner.

[0019] Preferably, at least one function knob corresponds to one display module, which facilitates precise control of different display modules.

[0020] A light source for illuminating the detection marking line and the quality control marking line is fixed on the bottom surface of the shell cover. The light source is powered by the time display component to facilitate judging the detection process and obtaining the detection result.

[0021] A light source switch is provided outside the cover. The light source switch is signal-connected to the display module of the time display component, so that the brightness and darkness of the light source can be controlled, achieving a concealed effect while saving resources.

[0022] The detection display window is arranged at the middle position between the quality control display window and the sample adding hole. Since the sample runs on the plate and encounters the detection line first and then the quality control line, the relative position is set.

[0023] There is at least one time display component. To conceal the detection device, common functions need to be added to the shell cover to confuse the line of sight, so at least one time display component needs to be set.

[0024] Preferably, the time display component can display the calendar function.

[0025] The number of reagent strips is 1 - 5.

[0026] Preferably, sample pads with different quantities and different test substances can be installed according to the detection requirements to detect multiple samples. Assembling different types of reagent strips can detect different types of drug abuse, increasing the detection items and improving the efficiency. Assembling the same reagent strips can reduce the result error and improve the accuracy.

[0027] The filler of the sample adding hole is non-woven fabric. As a flexible material, the non-woven fabric can adsorb the liquid sample and slowly release it onto the sample pad of the reagent strip, preventing the liquid sample from directly pouring in and submerging the reagent strip, resulting in the failure of the reagent strip. At the same time, it can reduce the overflow and loss of the liquid sample.

[0028] Compared with the prior art, the beneficial effects of the present utility model are:

[0029] 1. A detection component is arranged in a fixed shell body. A time display component is provided on the fixed shell body, and a bracelet is connected to the fixed shell body to conceal the detection device and facilitate carrying at the same time.

[0030] 2. The detection component only includes the filler of the sample adding hole and the sample pad, which simplifies the operation steps. At the same time, there is no requirement for the surrounding environment during detection, and the applicable range of the device can be increased.

[0031] 3. The design of the sample addition hole filler can adsorb the liquid sample and slowly release it onto the sample pad of the test strip, preventing the liquid sample from directly pouring into and submerging the test strip, which may cause the test strip to fail. At the same time, it can reduce the overflow and loss of the liquid sample and enhance the usability of the device. Description of the Drawings
