Description

Pharynx swab collection module with image acquisition function
Technical Field
The invention relates to the technical field of image processing, in particular to a throat swab acquisition module with an image acquisition function.
Background
The normal oral cavity normal flora is cultured in the angina of a normal person without the growth of pathogenic bacteria. The bacteria in the pharynx come from the outside, and normally do not cause diseases, but the body can have lowered resistance in the whole body or part and other external factors can cause infection and the like to cause diseases. Therefore, the bacterial culture of the pharyngeal swab can separate out pathogenic bacteria, and is beneficial to diagnosis of diphtheria, suppurative tonsillitis, acute pharyngolaryngitis and the like. Pathogenic bacteria were detected in sputum and throat swab secretions and were considered respiratory infections. The respiratory tract infection site can be diagnosed in combination with other examinations (X-ray fluoroscopy, B-ultrasound, etc.). Common bacteria for respiratory tract infection are: staphylococcus, Diplococcus pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus, Streptococcus pyocyaneus, Escherichia coli, etc. If tubercle bacillus is cultured, it is pulmonary tuberculosis. If yeast-like yeast is cultured, whether the antibiotic is used improperly or excessively during infection is considered, the antibiotic should be stopped immediately, and antifungal drugs, such as amphotericin B, griseofulvin, clotrimazole and the like, are used instead.
Pathogenic bacteria were detected in throat swab secretions and were considered respiratory infections. The respiratory tract infection site can be diagnosed in combination with other examinations (X-ray fluoroscopy, B-ultrasound, etc.). If yeast-like yeast is cultured, whether the antibiotic is used improperly or excessively during infection is considered, the antibiotic should be stopped immediately, and antifungal drugs, such as amphotericin B, griseofulvin, clotrimazole and the like, are used instead. When detecting respiratory tract infection parts, a small amount of secretion is dipped from the pharynx of a person to be detected by a sterilized medical long cotton swab, and then respiratory tract virus detection is carried out. The detection method comprises making an order for the patient to open mouth to send out an 'o' sound, fully exposing pharynx, wiping secretion on the pharyngeal and palatal arches and tonsils on two sides with a long cotton swab, rapidly placing the cotton swab into a test tube with a detection function after collection, sealing, and timely inspecting. Although the method can be used for taking secretions from pharynx and tonsil for bacterial culture and detecting pathogenic bacteria so as to judge whether respiratory tract infection diseases exist or not, the detection capability of the respiratory tract infection parts can be improved to a certain extent, but the method is more traditional and old, and the diseased result can be obtained by detecting the detected data information through practice, so that the method is low in efficiency.
