Description
Technical Field
The utility model particularly relates to a suction type nasopharynx swab.
Background
When diseases such as respiratory tract infection cause pathological changes, bacteria or viruses such as streptococcus, staphylococcus and the like can be parasitic in throat or nasal cavity. Particularly, in seasons with frequent influenza, the influenza is often spread through sneezing, coughing and the like, and samples in the throat or nasal cavity need to be collected for assay diagnosis in the process of visiting a doctor, so that secondary collection of medical staff due to insufficient sample collection needs to be avoided, and thus enough assay samples need to be collected at one time in the collection process.
A nasopharyngeal swab is a common medical tool used for taking a nasopharyngeal site specimen. When the nasopharynx portion of patient is sampled to needs, adopt the nasopharynx swab to sample for the guarantee safety and sanitation usually, the patient opens the mouth promptly and exposes the nasopharynx portion, and medical personnel stretch into the nasopharynx portion with the nasopharynx swab and clean the collection sample to make things convenient for subsequent detection and analysis. As shown in fig. 1, the existing nasopharyngeal swab mainly includes a solid swab stick, one end of the swab stick is fixed with a cotton ball, and the other end is fixed with a plug, and the nasopharyngeal swab is placed in a plastic tube for storage after sampling. The existing nasopharyngeal swab has the defects that the collected sample is insufficient in the sampling process, and the phenomenon that a patient bites off the swab stick when the throat part is collected as the sample is easy to occur, so that the phenomenon that enough sputum cannot be collected for detection and analysis is caused. Therefore, a new suction-type nasopharyngeal swab is needed to collect enough sample in the nasopharynx for detection.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: provides a suction type nasopharyngeal swab which can collect enough samples to be detected and has simple operation and simple structure.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the suction type nasopharyngeal swab comprises a fixed plug and a hollow swab body, wherein the swab body penetrates out of the fixed plug, one end of the swab body is provided with a negative pressure component communicated with the hollow part of the swab body, the fixed plug and the swab body are fixed and close to the negative pressure component, and the other end of the swab body is provided with a sampling component.
Preferably, the swab body is a hollow plastic rod, the plastic rod is made of a material with higher hardness than a cotton swab rod, and the swab body is not easy to be bitten off by a patient, so that the safety of the nasopharyngeal swab is improved.
Preferably, the material of sampling component be the foam, adopt the foam can make its fixed more firm with the swab body of plastics material, avoid appearing the situation that traditional cotton ball drops from the cotton swab stick, further improve nasopharynx swab's practicality and security.
Preferably, the negative pressure component is a compressible dropper head.
Preferably, the fixing plug is in a circular truncated cone shape. The suction type nasopharynx swab further comprises a packaging tube matched with the fixing plug, the packaging tube is a plastic tube with an opening at one end, and the opening end of the packaging tube is matched with the fixing plug; the device has the advantages that the truncated cone-shaped fixing plug can be pressed in the opening end of the packaging tube matched with the truncated cone-shaped fixing plug, so that the unused nasopharynx swab is sealed and stored, the used nasopharynx swab is reliably sealed, the pollution of external impurities is prevented, and the reliability of collecting samples by the nasopharynx swab is improved.
Compared with the prior art, the utility model has the advantages that adopt hollow structure's swab body, the one end setting of swab body is linked together with well kenozooecium simultaneously, can be with its inside air escape through extrusion negative pressure component, then stretch into in the throat or the nasal cavity with the other end of swab body, thereby inhale the well kenozooecium of swab body with the sample that awaits measuring such as sputum of the internal patient, compared in traditional swab greatly increased the sample's the volume of gathering, the other end of swab body still is provided with the sampling component simultaneously, can glue through the sampling component equally and get the internal sample of examining of treating of patient, thereby increase this suction type nasopharynx swab's practicality, avoid carrying out the secondary collection because of the volume of examining the sample is not enough, when reducing medical personnel's work load, reduce medical personnel and expose the risk in the flu environment.
Drawings
FIG. 1 is a schematic view of a nasopharyngeal swab of the prior art;
FIG. 2 is a schematic view of the suction type nasopharyngeal swab of the present invention;
fig. 3 is the sealing tube matched with the fixing plug in the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
The suction type nasopharyngeal swab comprises a fixed plug 1 and a hollow swab body 2, wherein the fixed plug 1 is in a round table shape, the swab body 2 is a plastic rod formed by plastic, the fixed plug penetrates out of the swab body 2, one end of the swab body 2 is provided with a negative pressure component 3 communicated with the hollow portion, the fixed plug 1 is fixed with the swab body 2 and is close to the negative pressure component 3, and the other end of the swab body 2 is provided with a sampling component 4 formed by the plastic rod. The nasopharyngeal swab is higher in safety because the plastic rod is higher in hardness compared with a cotton swab rod, and the swab body is not easy to be bitten off by a patient; the material of sampling component is the foam, adopts the foam can make its fixed more firm with the swab body of plastics material, avoids appearing the situation that traditional cotton ball drops from the cotton swab stick, further improves nasopharynx swab's practicality and security.
