Description

Sample sampler is gathered to pharynx swab

Technical Field

The utility model relates to a medical treatment appurtenance field especially relates to a sample sampler is gathered to pharynx swab.

Background

The identification of respiratory infectious diseases requires nucleic acid detection, which is roughly divided into two steps: firstly, collecting a patient sample; secondly, detecting by a detection center. In the first step of sample collection, the requirement on the collected position is high, the sample must reach the pharyngeal back wall or tonsil, otherwise, the detection accuracy is affected, a doctor generally prepares a reagent stick (pharyngeal swab) similar to a long cotton stick and a sampling tube, a patient takes off a mask, then opens the mouth to send out 'o' sound, so that the pharyngeal back wall can be exposed, at this time, the doctor stretches the reagent stick to the pharyngeal back wall of the patient, applies and samples, and finally puts the sample into the sampling tube to be sealed, and sampling is completed.

However, the existing throat swab sample sampler formed by matching a throat swab and a sampling tube has the following defects in use:

firstly, sampling is inconvenient, and after a pharynx swab is used for collecting virus samples in oral epidermic cells or nasal cavities, the samples need to be stored in a collecting tube and then transferred to a laboratory for detection, a common pharynx swab handle is provided with an annular groove at present, after sampling is finished, a swab is placed in the collecting tube, the handle is broken, and a cover is covered to finish sampling, but when the handle is broken, the broken part is the annular groove and is difficult to break, so that the pharynx swab can be broken for many times, sampling is inconvenient, the cover of the collecting tube is difficult to cover easily, and liquid leakage causes pollution;

secondly, the resource waste is serious, as the collecting tube and the throat swab are generally packaged respectively, more packaging garbage is easily generated after the sampling is finished, so that the social resource waste is caused, and in addition, a large amount of gun heads are consumed in the process of sucking samples from the collecting tube by using a pipettor and the gun heads, so that more medical wastes are generated;

thirdly, the sample is easy to be polluted when being sucked during detection. The storage tube which is commonly used at present is inconvenient to sample. Because there is the sampling swab in the sampling pipe, so use pipettor and rifle head to take out the in-process of appearance in the sampling pipe and take out the condition of the sample difficulty easily to cause and take out the sample inaccurate, simultaneously, because the sampling pipe is usually darker, so the pipettor need stretch into in the sampling pipe just can take out the sample, this makes the pipettor receive the pollution easily, thereby causes subsequent cross contamination.
