Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an oral swab sampler. Background Art

[0002] The swab is mainly composed of two parts: the swab stick and the swab head. The traditional swab fixes the fiber at the end of the swab stick by bonding, heat sealing or electrostatic flocking, and has strict requirements on the hygiene of the production and use of the swab head. If contamination occurs, it will affect the accuracy of sampling and detection. During sampling, if the swab head is collected by the staff after the collection is completed, the swab head needs to be immersed in a sampling tube containing virus preservation fluid. Especially in the case of mixed sampling, the swab head needs to be broken off from the swab stick and put into the tube, which is inconvenient for the staff to use. Utility Model Content

[0018] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Combined with Figures 1 to 5 An oral swab sampler comprises a connecting tube 1, a push rod 2, a sleeve 3 and a fiber head 12. The connecting tube 1 is provided with a push rod 2 and a fiber head 12. The upper end of the push rod 2 passes through the upper end of the connecting tube 1. The push rod 2 is arranged above the fiber head 12. The lower end of the connecting tube 1 is provided with a sleeve 3, which is sleeved on the connecting tube 1. The lower end of the sleeve 3 is provided with a sealing flap 6.

[0020] The connecting tube 1 has slide grooves 4 distributed on its side, each slide groove 4 is axially arranged, a first clamping ring 7 is provided at the lower end of the connecting tube 1, and the side of the first clamping ring 7 is connected to the inner wall of the connecting tube 1, a second clamping ring 8 is provided above the first clamping ring 7, and the side of the second clamping ring 8 is connected to the inner wall of the connecting tube 1.

[0021] A pressure block 5 is provided at the upper end of the push rod 2, and the lower end of the push rod 2 is arranged between the first clamping ring 7 and the second clamping ring 8. A limiting ring 11 is provided on the side of the lower end of the push rod 2, and the inner wall of the limiting ring 11 is connected to the side of the push rod 2. The limiting ring 11 moves between the first clamping ring 7 and the second clamping ring 8 to prevent the push rod 2 from detaching from the connecting tube 1.

[0022] A connecting ring 9 is provided at the upper end of the sleeve 3, the lower surface of the connecting ring 9 is connected to the upper surface of the sleeve 3, the connecting ring 9 and the sleeve 3 have the same central axis, and a slider 10 is distributed on the inner wall of the connecting ring 9. The slider 10 is arranged corresponding to the slide groove 4, and the slider 10 is arranged in the corresponding slide groove 4 to facilitate the sliding of the sleeve 3 at the lower end of the connecting pipe 1.

[0023] The lower surface of the sleeve 3 is distributed with sealing petals 6, the upper surface of each sealing petal 6 is connected to the lower surface of the sleeve 3, and the sealing petals 6 are equidistantly arrayed on the lower surface of the sleeve 3. The side surfaces of two adjacent sealing petals 6 are bonded to each other, and each sealing petal 6 wraps the fiber head 12 under the connecting tube 1.

[0024] A connecting rod 13 is provided at the upper end of the fiber head 12, and the upper end of the connecting rod 13 is arranged in the connecting tube 1. The connecting rod 13 is arranged between the first clamping ring 7 and the second clamping ring 8. Blocks 14 are distributed on the sides of the connecting rod 13. The push rod 2 squeezes the connecting rod 13 so that the block 14 passes through the first clamping ring 7, thereby separating the fiber head 12 from the connecting tube 1 and falling into the virus preservation liquid in the sampling tube.

[0025] An oral swab sampler described in the embodiment is used by holding the upper end of the connecting tube 1 and dragging the sleeve 3 upwards, so that the bottom of the fiber head 12 rests on each sealing flap 6, thereby separating each sealing flap 6, and continuing to slide the sleeve 3 upwards until each sealing flap 6 is above the connecting tube 1, exposing the fiber head 12 to the outside, and then the staff holds the end of the connecting tube 1 for sampling. After the sampling is completed, the fiber head 12 is placed in the virus sampling tube, and the connecting tube 1 is held and the pressure block 5 is pressed downward, so that the lower end of the push rod 2 squeezes the upper end of the connecting rod 13, so that the clamping block 14 passes through the first clamping ring 7, so that the fiber head 12 is separated from the connecting tube 1 and falls into the virus preservation liquid in the sampling tube to complete the sampling.

[0026] The parts of the present invention that are not described in detail are prior art. Although the present invention is specifically demonstrated and introduced in conjunction with the preferred implementation scheme, there are many methods and ways to implement the technical solution. The above is only a preferred implementation scheme of the present invention. However, technical personnel in the relevant field should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined in the attached claims, which are all within the scope of protection of the present invention.
