Sampler and sampling equipment

Abstract

The sampler comprises a sampling probe, a telescopic piece and a sampling test tube, the sampling probe is connected with the telescopic piece, the sampling test tube comprises a containing cavity, the containing cavity is provided with a first opening, the telescopic piece is arranged at the first opening and seals the containing cavity, and the telescopic piece and the sampling test tube are both made of elastic materials; when the sampling test tube is in an initial state, the telescopic piece and the sampling probe are accommodated in the accommodating cavity; when the sampling test tube is pressed, the telescopic piece drives the sampling probe to extend out of the accommodating cavity for sampling. The sampling probe is connected with the telescopic piece, and the telescopic piece can drive the sampling probe to sample by pressing the sampling test tube; the sampling probe can be driven to retract into the sampling test tube through the telescopic piece by releasing the sampling test tube. The telescopic piece is of a flexible structure, the sampling head is driven by the telescopic piece to sample, stimulation of the sampling probe to the nasopharyngeal cavity in the sampling process can be reduced, the experience of a sampled person is improved, and meanwhile the sampling success rate is increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a sampler and sampling equipment. Background technique [0002] Nucleic acid testing plays an important role in the diagnosis of new coronavirus pneumonia. In order to prevent the spread of new coronary pneumonia, many cities have proposed national nucleic acid sample collection and testing projects. At present, nucleic acid samples are generally collected by nasopharyngeal sampling. Existing nasopharyngeal sampling uses hard nasopharyngeal swabs to pass through the lower nasal cavity to the sampling area of ​​the posterior wall of the nasopharyngeal cavity. It is easy to irritate the nasopharynx of the human body and cause problems such as runny nose and tears, mucous membrane congestion and edema. Contents of the invention [0003] The purpose of the present invention is to provide a sampler and sampling equipment, which can reduce the stimulation of the sampling hea...
