Description

Throat swab sampling system for medical disease diagnosis

Technical Field

The invention relates to the technical field of medical instruments, in particular to a throat swab sampling system for medical disease diagnosis.

Background

Pharyngeal and tonsillar secretions collected for bacterial culture or viral isolation are diagnostic methods often used to examine disease. The bacteria in the pharynx come from the outside, and are not ill under normal conditions, but the bacteria may cause diseases due to the decrease of systemic or local resistance of the body and other external factors, such as infection. The pharyngeal swab bacterial culture can collect pharyngeal and tonsil secretions and separate pathogenic bacteria, and is helpful for diagnosing diphtheria, suppurative tonsillitis, acute pharyngolaryngitis and other diseases.

On the other hand, throat swab nucleic acid detection is a main index for diagnosing novel coronavirus infection. The throat swab specimen is a medical cotton swab, a small amount of secretion is dipped in the throat (rear pharyngeal wall) of a human body, the taken sample is the throat swab specimen, and the virus type can be conveniently, quickly and accurately detected through the throat swab in order to detect the virus type of the respiratory disease.

However, in the process of taking a sample, because the physician has improper force or excessive collecting action, the physician is very easy to touch the palatopharyngeal arch (two sides of the back wall of the pharynx) of the patient, which causes the patient to have a strong pharyngeal reaction, and the patient feels uncomfortable and is also hindered from normal operation.

In patent document CN202022072179.5, a pharynx swab sampling device is disclosed, which comprises a pharynx swab holding device and a pharynx swab, wherein the pharynx swab holding device comprises a base, and a rotary driving mechanism and a crank slider mechanism which are arranged on the base, wherein the rotary driving mechanism is used for providing a rotary driving force; the slider-crank mechanism is connected with the rotary driving mechanism, and the throat swab is connected with the slider-crank mechanism; the crank-slider mechanism is used for driving the throat swab to swing and enabling the tail end of the throat swab to continuously move on an elliptical track. The device can reliably collect the pharyngeal and tonsil secretions of the patient, effectively reduce the stimulation to the pharyngeal of the patient and reduce the pharyngeal reaction degree of the patient.

However, the following disadvantages still exist in the practical application process:

firstly, the security is not good because the doctor is when being carried out pharyngeal sample collection to the person being gathered, the oral cavity of the person being gathered is just to doctor's face, although protective equipment such as gauze mask and goggles are worn to doctor's face, this can make doctor's gauze mask and goggles become dirty fast (because there are trace saliva and gas direct injection to doctor's facial gauze mask in the person being gathered's mouth) to the protection that pierces through the gauze mask invades doctor's oronasal.

Secondly, the collection effect is poor, because the oral cavity is a relatively narrow space, and the pharyngeal portion is deeper and narrower than the oral cavity, so that it is difficult for a doctor to see the position of the end of the pharyngeal swab in the mouth of the person to be collected, which is more obvious in the dark environment such as night, that is, the qualification rate of the pharyngeal swab sample collected by the doctor cannot be effectively guaranteed.

Thirdly, the continuous collection difficulty is high, because the doctor needs to ceaselessly repeat the action of lowering the head and bending the waist when collecting the sample, the physical consumption of the doctor is high, and the physical health of the doctor is not facilitated; in addition, when a doctor manually collects a sample, the friction between the end part of the pharyngeal swab and the pharyngeal surface wall of a person to be collected is insufficient due to fatigue, namely, the sampled sample is unqualified, or the action amplitude of the doctor is too large, so that the person to be collected has a strong physiological discomfort reaction.
