A sampling rod capable of collecting throat swabs and preparation method thereof

Abstract

The invention provides a sampling rod capable of collecting throat swabs, comprising: a support rod, which is a cylindrical structure; a sampling head, which is a circular truncated structure, and one end of a narrow surface is coaxially connected to one end of the support rod, and a wide surface is integrally connected. One end is a convex arc surface; a porous sampling layer is arranged on the outer surface of the sampling head; the average pore diameter of the porous sampling layer is 5-50 μm, and the porosity is 60-90%. The sampling stick designed and developed by the present invention for collecting throat swabs is provided with a sampling head wrapped with a porous sampling layer, which can effectively absorb the throat swab without using a cotton swab head and avoid the cotton wool sticking to the human body. The present invention also provides a method for preparing a sampling rod capable of collecting throat swabs, which optimizes the mass ratio of the template agent solution and the porous sampling layer material solution and the thickness of the porous sampling layer, effectively adjusts the porosity of the porous sampling layer, and ensures the pharyngeal swab. The adsorption rate of the swab.

Description

technical field [0001] The present invention relates to the technical field of biological materials, and more particularly, to a sampling rod capable of collecting throat swabs and a preparation method thereof. Background technique [0002] Respiratory tract infection is usually determined by collecting throat swabs to determine the type of virus infection, and throat swab collection and testing is also a common method to determine whether someone is infected with a certain respiratory disease. [0003] Chinese utility model patent 201721030333.4 discloses a disposable throat swab collector, including a bottle body, a physiological saline stick, a bottle cap and a cotton swab, and the cotton swab includes a cotton swab rod and a cotton ball. Pharyngeal swabs are collected by cotton swabs, but the cotton wool-like cotton swab head is easy to stick to the human body when sampling, so the sampling effect is not good, and because the cotton swab head is installed on the wooden s...

AI Technical Summary

Problems solved by technology

Pharyngeal swabs are collected by cotton swabs, but when the cotton swab head is used for sampling, the cotton wool on it is easy to stick to the human body, the sampling effect is not good, and because the cotton swab head is installed on a wooden stick, the patient's body is also damaged during sampling. Mucous membranes, poor overall comfort

[0004] Chinese utility model patent 201820149976.9 discloses a throat swab specimen collection device, including a specimen container and a sampling stick. The sampling stick is made of hard rubber tube material, and the sampling head of the sampling stick is an elliptical or spherical structure, and is made of silica gel. Material, but the surface of the silicone material is smoother than the surface of the cotton swab head, and the adsorption capacity of the throat swab is poor, which may affect the test results
