Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sample collection equipment, in particular to a disposable specimen collection preprocessing device. Background Art
[0002] At present, all the collection containers involved in biological, medical, environmental and chemical specimen testing on the market are empty vessels, or samplers pre-loaded with a single type of sustained-release liquid. This brings a lot of inconvenience to some experiments that need to add two or three diluents. Because some tests require multiple sustained-release liquids, multiple sustained-release liquids cannot be mixed together in advance for preparation. Mixing multiple sustained-release liquids together in advance will affect the shelf life of the sustained-release liquids and the accuracy of the test results. Therefore, some specimen tests can only be done by preparing the sustained-release liquid immediately after sampling. Therefore, how to solve the above-mentioned problems has become a difficult problem that needs to be solved urgently. Utility Model Content
[0003] The purpose of the utility model is to provide a disposable specimen collection pretreatment device which has a simple structure, is easy to operate and use, and can selectively release two or more sustained-release liquids as needed while taking into account the basic functions of a traditional sampling stick, thereby avoiding affecting the shelf life of the product due to the advance preparation of some sustained-release liquids, and can effectively improve the accuracy of sample testing.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disposable specimen collection pretreatment device, which includes a liquid collecting tube, a side surface of a head at one end of the liquid collecting tube is connected to a specimen tube through a puncture connector, the inner side of the liquid collecting tube is contact-connected to a glass liner through an inner wall villi, a head at one end of the puncture connector is connected to a sampling rod through a card slot, a breathable drip nozzle is provided at the top of the specimen tube, a drip nozzle cover is connected to the outer side of the breathable drip nozzle through a drip nozzle thread, and the liquid collecting tube and the puncture connector are connected through a thread.
[0005] Preferably, the puncture connector is configured as a hollow structure, a guide groove is provided on the inner side of the puncture connector, the guide groove is connected to the card slot, a specimen tube sealing card slot is provided on the outer side of one end of the puncture connector, and the specimen tube sealing card slot is connected to the open end of the specimen tube.
[0006] Preferably, the sampling rod is configured as a hollow structure, and a sampling contact terminal is provided at one end of the sampling rod.
[0007] Preferably, the inner wall of the drip cover is provided with a drip cover thread corresponding to the drip thread, one end of the drip cover is provided with an access groove, and one end of the inner wall of the drip cover is provided with a drip plugging protrusion.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] (1) The utility model has a simple structure and is easy to operate. While taking into account the basic functions of a traditional sampling stick, it can also select to release two or more slow-release liquids according to needs, thereby avoiding the influence of timeliness on the test results and effectively improving the accuracy of sample testing. During operation, the slow-release liquid will not flow out unless the liquid collecting tube is twisted. When the slow-release liquid is needed after the sampling is completed, the liquid collecting tube can be slightly twisted. When multiple slow-release liquids are needed, the glass liner inside the liquid collecting tube can be crushed.
[0010] (2) The liquid collection tube can be used to store sustained-release liquid. The fluff on the inner wall of the liquid collection tube can prevent the glass liner from puncturing the liquid collection tube after breaking. The fluff on the inner wall also has a buffering and shock-absorbing function, which can effectively prevent the glass inner tube from breaking due to bumps when not needed. The puncture connector can connect the liquid collection tube and the sampling rod at the same time, and connect the specimen tube through the card slot. The specimen tube can protect the sampling rod during non-sampling time. When the sampling rod has finished sampling, the specimen tube can be reset to preserve the sample for several hours.
[0011] (3) The breathable drip nozzle can prevent the humidity or temperature inside the specimen tube from being too high when storing the sample. The drip nozzle cover can protect the sampling rod from contamination before the device is activated. The guide groove can guide the slow-release liquid to flow out along the inside of the sampling rod. The specimen tube sealing card can firmly fix the specimen tube to prevent dust from entering. The access groove can better fit the top curved surface of the specimen tube. The drip nozzle sealing protrusion can better fit the hole of the drip nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

The connection between the components can also be connected through an annular sealing step. The drip nozzle cover does not need to be removed in normal status. Only when the collected samples need to be preserved, the drip nozzle cover will be removed as needed. If multiple devices are packed together for storage and transportation, the drip nozzle cover needs to be improved to prevent cross-contamination of the collected samples. In order to prevent the slow-release liquid from flowing out, the outlet end of the collecting tube can be packaged with easy-to-puncture aluminum foil. When the slow-release liquid needs to be released, the aluminum foil interface is pierced with a sampling rod, or the collecting tube can be rotated so that the guide groove pierces the aluminum foil.
[0021] The puncture connector 2 is configured as a hollow structure, a guide groove 12 is provided on the inner side of the puncture connector 2, the guide groove 12 is connected to the card slot 6, a specimen tube sealing card slot 13 is provided on the outer side of one end of the puncture connector 2, the specimen tube sealing card slot 13 is connected to the open end of the specimen tube 3, and the puncture connector can also be provided with a switch to ensure that the sustained-release liquid does not flow out through the internal space of the sampling rod when the sustained-release liquid is not needed to be released.
