Abstract
Description
Technical Field
[0001] The present application relates to the technical field of nucleic acid detection, and in particular to a flexible throat swab sampling device. Background Art
[0002] Confirmation of respiratory infectious diseases requires nucleic acid testing, which is roughly divided into two steps: 1) Collecting patient samples; 2) Testing at the testing center. The first step of sample collection has relatively high requirements on the collection location, and it must reach the posterior pharyngeal wall or tonsils, otherwise it will affect the accuracy of the test. Doctors generally prepare a reagent stick (throat swab) similar to a long cotton swab and a reagent tube. The patient should take off the mask, then open his mouth and make an "ah" sound to expose the posterior pharyngeal wall. At this time, the doctor extends the reagent stick to the patient's posterior pharyngeal wall and smears it for sampling. Finally, put the sample into the reagent tube and seal it to complete the sampling.
[0003] During the sampling process, patients inevitably feel uncomfortable. Sometimes patients feel nauseous, choke, and cough. A lot of gas carrying viruses will come out of the patient's mouth, and even a lot of splashing liquid will come out. The virus directly hitting the face greatly increases the risk faced by medical staff, and even causes some medical staff to be cross-infected. In addition, during the manual sampling process, due to the differences in the operating skills of different medical staff and the irregularities in the collection process, the quality of the swabs varies, which is prone to false negatives and affects the judgment of the condition.
[0004] Therefore, it is desired to have a technical solution to overcome or at least alleviate at least one of the above-mentioned defects of the prior art. Summary of the invention

[0089] The origami structure 14 is configured to be twisted in the axial direction of the flexible throat swab body under the action of the gas entering the airway, and to be stretched in the third direction under the action of the gas.
[0090] The origami structure 14 uses an elastic material with a low Young's modulus (such as soft materials such as silicone) and an origami structure. Through the design of the uneven elastic body structure at the fold, the actuator has origami-like characteristics, with a large expansion ratio and torsion ratio. The extension and torsion are achieved by filling with gas. It has the performance of passive deformation, so that it can passively adapt to different complex surfaces.
[0091] When in use, the origami structure will passively bend when encountering the inner wall of the user's mouth, so that the sampling part on the origami structure can bend and twist on the inner wall of the mouth, thereby achieving better sampling.
[0092] See also Figures 6 to 8 In this embodiment, the origami structure 14 is in an uninflated state. Figure 6 As shown, under the action of the gas entering its airway, see Figure 7 Due to the structural characteristics of the origami structure, the origami structure stretches on one hand and rotates on the other hand under the action of gas (as can be seen from the position of the sampling part on the origami structure). When filled with gas, Figure 8 Same as shown.
[0093] While achieving anti-fatigue and long-life sports, it can resist chemical erosion for a long time and can interact safely with human organs. Its softness and elongation characteristics can minimize the patient's discomfort when contacting the throat, while extending down along the posterior pharyngeal wall to achieve deeper posterior pharyngeal wall sampling, and the torsion characteristics can drive the terminal sampling head to obtain more samples.
