Description

Clamping separable type detection kit for new coronavirus throat swab

Technical Field

The utility model relates to a virus sample class medical instrument field particularly, relates to a press from both sides tight detachable new crown pneumonia virus pharynx swab and detect suit.

Background

Nucleic acid detection is an important part for accurate diagnosis of the new coronary pneumonia, and in the nucleic acid detection, sampling is often carried out by a pharyngeal swab. The existing throat swab sampling method uses a tongue depressor, a sampling person needs to directly look at the oral cavity of a detected person to finish the sampling, and the method has the following defects:

1. existing pharyngeal swab heads are essentially football-like shuttles, which are capable of wiping and sucking sufficient secretions from the faucial pillars and tonsils on either side of the throat. However, the close-faced surface of the fusiform end of the throat-shaped medical instrument is too small to be attached to the posterior pharyngeal wall of the back part of the throat, and sufficient and comprehensive secretion cannot be effectively collected through the end, and because the detection result is inaccurate due to the insufficient secretion, the judgment of medical staff on the state of an illness and the situation is directly influenced.

2. Present pharynx swab adopts the break point to separate the swab sampling head for the design of breakable in connecting rod department, nevertheless often can have the break point to be in the difficult circumstances of breaking after buckling, lead to unable separation swab sampling head to preserve alone, the mode of adopting the break of buckling is usually comparatively slow simultaneously, need buckle many times, can't separate in the culture solution is put into to the first time separation swab sampling head after accomplishing the sample, virus loses partial activity in the secretion that can lead to the sample, make the detection degree of difficulty increase, detect the accuracy and reduce.

3. When the existing throat swab is used for sampling, the existing throat swab needs to extend into the position of the throat of a detected person, so that the situation that light is insufficient inevitably exists, and the situation that the throat area cannot be seen clearly due to the fact that the tongue of the detected person blocks the sight can also occur. Often, medical staff need hold lighting equipment such as a pharynx swab with one hand and a flashlight with the other hand, and two hands are respectively controlled and are increased medical staff's the sample degree of difficulty, probably lead to pharynx swab to clean the dynamics inhomogeneous for the secretion sample is not enough. Meanwhile, the swab sampling head is broken at the broken point due to the uneven force, and the swab sampling head falls into the esophagus or trachea of the detected person, so that unnecessary potential safety hazards are caused.

4. The existing throat swab is matched with the protective cover for synchronous use, but the existing protective cover is simply provided with the round hole for the arms of medical staff to penetrate through for operation, but the spray of a detected person easily penetrates through the vacancy gap between the arms of the medical staff and the round hole to reach the area where the medical staff is located during operation. If the detected person is a virus carrier or an infected person, medical staff has great hidden danger of infection.

5. Present pharynx swab is separately independent sealed package with the collection pipe, unseals earlier during unsealing and seals the pharynx swab packing, takes out again and gathers the pipe and unseal, and first repeated unsealing can waste too much time, and the second can make the pharynx swab expose time overlength in the air when unsealing alone and gathering the pipe, especially in the higher environment of virus concentration in the air, very pollutes the pharynx swab easily, leads to the testing result inaccurate. And batch pharynx swab individual packaging all is scattered and places, and the inconvenient centralized unified management that carries on, and the scattered placing of pharynx swab that is unpacked can occupy too much platform area when using.
