Problems solved by technology

However, it is relatively difficult to use nasopharyngeal swabs for sample collection, and the existing nasopharyngeal swab collection methods and devices bring significant discomfort to patients, and it is difficult for people without professional training to use nasopharyngeal swabs The swab head is inserted into the nasopharynx, or the nasopharyngeal swab stays in the nasopharynx for insufficient time, and the amount of secretions collected is insufficient, which eventually leads to sample collection failure and subsequent false negatives in nucleic acid tests (or a high false negative rate) Case

Embodiment 1

[0054] First a brief description of the nasal cavity structure and the sampling process of the prior art: nasal cavity structure see figure 1 The median sagittal section of the nasal cavity shows that there are inferior turbinates 3, middle turbinates 5, and superior turbinates 6 in the nasal cavity, and correspondingly formed inferior nasal passages 1, middle nasal passages 4, and superior nasal passages 7. Among them, the use of nasopharyngeal swabs for sample collection is to insert nasopharyngeal swabs from the lower nasal passage 1. The lower nasal passage 1 is a channel surrounded by the hard palate 9, soft palate 10, and inferior turbinate 3. One end of the lower nasal passage 1 opens in the nose. The vestibule 2 (the opening is called the entrance of the inferior nasal meatus 1 ), and the other end opens into the nasopharynx 8 . The procedure of nasopharyngeal 8 sampling using prior art nasopharyngeal swab is as follows: insert the head of the nasopharyngeal swab into ...

Embodiment 2

[0059] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the nasopharyngeal swab in the prior art has been improved.

[0060] The nasopharyngeal swab self-collection kit of this program includes such as: Figure 5 Shown nasopharyngeal swab, nasopharyngeal swab comprises swab head 11, connecting rod 12 and swab handle 13 three parts. The connecting rod 12 is a hollow cylindrical straight pipe with openings at both ends, and the connecting rod 12 is made of PVC material, which can support and push the swab head 11 through figure 1 The passage in the nasal cavity shown in the figure enters the nasopharynx 8, and the connecting rod 12 made of PVC has certain flexibility and can be slightly bent to adapt to the shape of the passage in the nasal cavity. The swab head 11 includes such as Figure 6 The shown cylindrical tubular central rod 14 with both ends open, the material and diameter of the central rod 14 are consistent with the c...

Embodiment 3

[0066] This embodiment is basically the same as Embodiment 2, and the difference lies in the structure of the swab head 11. In this embodiment, the swab head 11 is curved, such as Figure 8 As shown, the swab head 11 includes a swab head I part 36 and a swab head II part 37, and the angle between them is obtuse. More specifically: the central rod 14 includes an integrally formed rod I part and a rod II part (not shown in the figure), an obtuse angle is formed between the rod I part and the rod II part, and then the center rod 14 with a bend is covered Sponge layer15. When in use, insert the swab head 11 into the lower nasal passage 1 with the swab head I part 36 facing down and the swab head II part 37 perpendicular to the human face. Since the soft palate 10 has a curvature, the swab head 11 is curved so as to better fit the curvature of the soft palate 10 . Compared with the straight swab head 11, this solution can make the swab head 11 go deeper into the nasopharynx 8, an...

Abstract

The invention belongs to the technical field of biomedicine, and particularly relates to a nasopharyngeal swab self-help collection kit which comprises a nasopharyngeal swab, and further comprises a guide structure, wherein the guide structure comprises a guide substructure, and the guide substructure comprises a C-shaped tubular guide, one end of the guide part is opened at the entrance of the lower nasal passage, and the other end of the guide part is opened at the nostril on the same side of the lower nasal passage. The kit can realize self-service nasopharyngeal swab sampling for patients,assist patients to correctly insert nasopharyngeal swabs into the nasopharynx, improve the success rate of self-service sampling, and solve the high exposure risk of medical staff directly collectingsamples and the difficulty of self-service collection operations in technical issues. The scheme can be applied to medical practice operations such as sampling and testing of highly infectious respiratory infectious diseases such as new coronary pneumonia.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a set for self-service collection of nasopharyngeal swabs. Background technique [0002] In the medical practice of COVID-19 nucleic acid detection, oropharyngeal swabs and nasopharyngeal swabs are often used for sampling. Among them, the accuracy of nasopharyngeal swabs is higher than that of oropharyngeal swabs, so in the actual application process, nasopharyngeal swabs are more widely used. The existing nasopharyngeal swab includes a stem and a head (the nasopharyngeal swab is a thin and long cotton swab). Affect the sampling process; then put the head of the nasopharyngeal swab into normal saline to moisten, and then insert the nasopharyngeal swab into the nostril in a direction perpendicular to the face until the head of the nasopharyngeal swab reaches the nasopharynx, so that The swab stays in the nose for 15-30 seconds, then gently rotate the nasopharynge...
