Problems solved by technology

[0011] 1. After collecting nasopharyngeal swabs, the swabs with pharyngeal exudate need to be preserved with virus or cell preservation solution. Therefore, when collecting nasopharyngeal swabs, not only the nasopharyngeal exudate is required The sampler (nasopharyngeal swab) also needs to carry preservation containers (test tubes) and virus or cell preservation solutions, which brings trouble to the collection of nasopharyngeal swabs
[0012] 2. When collecting nasopharyngeal swabs, hold the handle in your hand. When storing, you need to break the handle and remove the part you hold to avoid contamination. This is more troublesome, especially for some swabs that are dipped in the nasopharynx at one end. Weeping collection head, it is very difficult to break off the tail, and sometimes you need to use tools

Embodiment Construction

[0023] This embodiment is a nasopharyngeal swab for collecting nasopharyngeal secretions and superficial epithelial cells, such as figure 1 , 2 , 3, including a flexible handle 2 and a collection head 1 with excellent water absorption performance arranged at the top of the handle 2; in this embodiment, the handle 2 is a plastic rod with good flexibility, and at its tip Form a spherical shape, so that when the nasopharyngeal swab is collected, the round top will not cause damage to the nostril of the collection object when the round top enters the nostril of the collection object, which is convenient for collection. In this embodiment, a nylon flocked swab with good water absorption performance is wrapped around the top of the handle 2 to form a collection head 1. As long as the collection head is in place (nasopharynx) during collection, the nasopharyngeal secretions or superficial epithelium.

[0024] In this embodiment, a storage container 5 in the shape of a test tube is ...

Abstract

The invention provides a nasopharynx swab which comprises a handle rod with flexibility and a collecting head which is arranged at the top end of the handle rod and has excellent water absorption performance so that trace detection materials such as saliva, blood, oral or nasal cavity secreta and superficial epithelial cells have excellent collecting performance; the nasopharynx swab further comprises a section of storage container in a test tube shape; an expanding part convenient to hold is arranged at the root of the handle rod, virus or cell conveying preservation liquid is sealed in the expanding part, an interface device sealed with an opening of the preservation container is arranged on the outer side of the expanding part, and when the collecting head is preserved in the preservation container, the expanding part is exposed out of the liquid level of the virus or cell preservation liquid in the preservation container. The root part of the handle rod of the swab is provided withthe expanding part which is used for storing the virus cell preserving fluid and is remained outside the preserving container during preservation so that the virus or the cell preserving fluid is notrequired to be broken off and removed while being stored, the use is more convenient, and the sampling safety is improved.

Description

technical field [0001] The invention relates to the field of nasopharyngeal swabs. Background technique [0002] Nasopharyngeal swabs are swabs used to collect nasopharyngeal samples and are used to detect bacteria and viruses after collection. The current general procedure for nasopharyngeal swab collection is as follows: [0003] 1. Please keep the patient's head still, and remove the secretions on the surface of the anterior nasal cavity. [0004] 2. Gently and slowly insert the swab through the nasal cavity to the nasopharynx. [0005] 3. When it encounters resistance, it reaches the posterior nasopharynx and stays for a few seconds to absorb secretions. After encountering resistance, adjust the angle and slowly reach the posterior nasopharynx. [0006] 4. Swirl gently to remove the swab and place it in the transfer medium. [0007] 5. For swabs used for virological testing, immerse the swab head in virus or cell preservation solution, discard the tail, and tighten ...
