Description

Technical Field

[0001] The invention relates to the technical field of oropharyngeal sampling, and in particular to a throat swab sampling clamping and cutting device. Background Art

[0002] Throat swabs are medical cotton swabs. By taking a small amount of secretions from the human throat and making a throat swab specimen for testing, the virus type of respiratory diseases can be detected quickly and accurately. In the process of using throat swabs for sampling, the sampling personnel usually hold the throat swab cotton swab stick and insert the cotton ball on the top of the cotton swab stick into the mouth of the person to be sampled for collection. After the collection is completed, the throat swab is taken out and placed in a collection container. At the same time, in order to improve the detection efficiency, multiple groups of throat swab samples are often placed in the same container for mixed testing.

[0003] However, the current mixed testing method is limited by the volume of the container. The number of swabs that can be stored in each container is limited, which will reduce the detection efficiency. Therefore, the swab is generally broken and only the cotton ball part at the end of the swab is placed in the container for collection. However, since the cotton swab stick itself is made of a highly tough material and is not easy to break, in order to facilitate the sampler to break the swab, it is often necessary to set tiny protrusions in the mold to form breakpoints when the swab is formed. This will cause the molding difficulty to increase sharply during mold processing, and the small protrusions are easy to wear, which greatly reduces the life of the mold.

[0004] In addition, due to the limitation of swab length, samplers usually sit in the sampling window during large-scale sampling, and are far away from the persons to be sampled. In some special cases, such as when the samplers or the persons to be sampled are short, samplers often need to lean out of the window and stretch their arms to reach the appropriate sampling distance, which causes certain troubles to the samplers' work and reduces the efficiency of sampling. However, if swabs with longer cotton swab sticks are used, the production cost of the swabs will increase, and the sampling price will be increased.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. Example

[0029] See also Figures 1 to 3 , a throat swab sampling clamping and cutting device, comprising a telescopic mechanism 2 and a tube body 1 sleeved on the outside of the telescopic mechanism, the telescopic mechanism being movably connected to the tube body to extend out of or sink into the tube body;

[0030] The extended end of the telescopic mechanism 2 is equipped with a clamping mechanism 3 and a cutting mechanism 4. The cutting mechanism is located outside the clamping mechanism. The clamping mechanism clamps or releases the swab as the telescopic mechanism moves.

[0031] The extended end of the telescopic mechanism 2 is also provided with a swab installation groove 22, and the clamping mechanism 3 includes a plurality of clamping claws 31, each of which is evenly distributed around the swab installation groove.

[0032] A retractable telescopic push rod 5 is provided in the tube body 1, and the telescopic mechanism 2 is connected and fixed to the telescopic push rod and is extended or retracted into the tube body through the telescopic push rod; a connecting seat 21 is fixed at the bottom of the telescopic mechanism 2, and the connecting seat is connected and fixed to the telescopic push rod to drive the telescopic mechanism; at least one pair of fixed rods 23 are also fixed to the protruding end of the tube body 1, and the cutting mechanism 4 is connected and fixed to the fixed rods.

[0033] The extended end of the telescopic mechanism 2 is also provided with a circular groove 24, and the swab installation groove 22 is arranged concentrically with the circular groove; an annular clamping sleeve 25 for limiting the clamping jaw 31 is fixed on the side wall of the circular groove 24, and the clamping jaw is located on the inner side of the clamping sleeve.

[0034] The jaws 31 are arranged opposite to each other and can move relative to or in opposite directions. The side of the jaws close to the ferrule 25 is an inclined surface, and the cross-section of the jaws gradually increases from the side close to the swab installation groove 22 to the side away from the swab installation groove.

[0035] An elastic member 311 is also provided between the clamping jaws 31, and both ends of the elastic member are respectively connected and fixed to two clamping jaws arranged opposite to each other. The elastic member 311 can not only limit the position of the clamping jaws to prevent the two relative clamping jaws from fitting together in the non-clamping state to interfere with the loading of the swab, but also drive the clamping jaws to automatically reset after the sampling is completed, thereby reducing the operation steps.

[0036] A base 32 is also provided in the circular groove 24 and is located between the ferrule 25 and the swab installation groove 22 . A through hole matching the swab installation groove 22 is provided on the base, and each clamping claw 31 is slidably fixed on the base.

[0037] A connecting rod movable groove 251 is formed at the bottom of the ferrule 25, and a connecting rod 33 inserted into and movable in the connecting rod movable groove is fixed on the base 32. The connecting rod and the connecting rod movable groove are provided with mutually adapted limiting parts to prevent the connecting rod from escaping from the connecting rod movable groove.

[0038] The cutting mechanism 4 includes a fixing seat 41 located between two fixing rods 23, a connecting portion 42 is provided between the fixing seat and the fixing rod, and the fixing seat is connected and fixed to the fixing rod through the connecting portion; an avoidance hole for avoiding the swab is opened on the fixing seat, and a cutting knife 43 and a matching portion 44 adapted to the avoidance hole are also installed on the fixing seat to facilitate cutting of the swab, and the distance between the fixing seat 41 and the protruding end of the telescopic mechanism 2 is smaller than the length of the clamping jaw 31, so that the fixing seat can limit the clamping jaw, and when the clamping jaw moves outward with the telescopic mechanism, the fixing seat 41 can resist the clamping jaw, so that the clamping jaw is tightened under the action of the clamping sleeve 25 to play a clamping role.

[0039] The tube body 1 is provided with a telescopic button 11 for controlling the telescopic push rod 5 and a cut-off button 12 for controlling the cut-off mechanism 4 for easy operation.

[0040] The fixing rod 23 is a hollow structure to form a connecting channel 231, in which a power line or a control structure connected to the cut-off mechanism 4 is provided, and the cut-off button 12 controls the cut-off mechanism to cut off the swab through the power line or the control structure. Specifically, the power line or the control structure controls the cut-off knife in the cut-off mechanism to perform a cutting operation and resets the cut-off knife after the cutting is completed, which is a conventional technical means for those skilled in the art and will not be described in detail here.

[0041] The throat swab sampling clamping and cutting device of this embodiment works as follows:

[0042] When in use, the sampling personnel holds the tube body 1 and inserts the cotton swab stick of the swab into the swab installation groove 22, presses the telescopic button 11, and the telescopic mechanism 2 moves toward the outside of the tube body 2 under the action of the telescopic push rod 5, driving the clamping jaw 31 to move outward. When the outer end of the clamping jaw abuts against the fixing seat 41 in the cut-off mechanism 4, the telescopic mechanism 2 continues to move. At this time, the clamping jaw 31 moves toward the circular groove 24 in the telescopic mechanism under the limit of the fixing seat 41. At the same time, under the action of the ferrule 25, due to the influence of the outer inclined surface of the clamping jaw 31, the two relatively arranged clamping jaws gradually move closer and clamp the cotton swab stick of the swab to complete the clamping of the swab. At this time, the length of the swab has been effectively extended under the action of the telescopic mechanism 2, which is convenient for the operator to collect samples;

[0043] When the cotton head at the front end of the swab is collected after the sampling is completed, the cut-off button 12 is pressed, and the cut-off knife 43 first moves with the matching part 44 and cuts off the cotton head of the swab for easy collection.

[0044] The beneficial effects of the present invention are as follows: through the cooperation between the telescopic mechanism and the tube body, the length of the swab can be increased without increasing the production cost of the swab, which makes it more convenient for the sampler to take samples; after the swab is cut off by the cutting mechanism, the cotton head of the swab is easier to collect, which also saves the time of the sampler and improves the sampling efficiency; in addition, since the telescopic mechanism and the cutting mechanism improve the flexibility of use and the breaking efficiency of the swab, there is no need to set a breakpoint for the mold when producing the swab, so that the swab production mold has a longer service life and reduces the production cost.

[0045] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify and vary the above embodiments within the scope of the present invention.
