Safety isolation device for sampling of respiratory system

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a safety isolation device for sampling of a respiratory system. The device comprises a protective cover and a disposable clamping piece; the protective cover comprises a cover body and a cover tube; the disposable clamping piece comprises a holding rod, and a rear baffle connected with one end of the holding rod is connected with a rear elastic clamping jaw and a connecting rod; a front elastic clamping jaw is connected to a connecting plate connected to one end of the connecting rod, a trapezoidal end is arranged at the end, away from the connecting plate, of the front elastic clamping jaw, and the outer side face of the connecting plate is connected with the middle end of the inner side face of a middle elastic clamping jaw. And a middle limiting block is arranged at one end of the middle elastic clamping jaw. Safe isolation protection is carried out in the sampling process through the protective cover which can be rapidly assembled and disassembled on the disposable clamping piece, and the disposable clamping piece clamping the cotton swab does not make contact with the hand of a medical worker or generate cross contamination before and after collection is finished; the safety is high, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a safety isolation device for respiratory system sampling. Background technique [0002] The culture of the isthmus of normal people should have normal oral flora without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and do not cause disease under normal circumstances, but infections can occur when the body's systemic or local resistance decreases and other external factors cause diseases. Therefore, bacterial culture of throat swabs can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, acute pharyngitis, etc. [0003] The operation process of oropharyngeal swab collection: 1. Ask the patient to sit down first, then ask the patient to tilt his head back, open his mouth wide, and first remove the secretions on the surface of the anterior nares; 2. The sampler...

Problems solved by technology

[0004] During the sampling process, the examinee opens his mouth and speaks and faces the examiner's face, and the germs can easily infect the examiner through droplets; adding an umbrella-shaped isolation cover can effectively reduce the droplet infection of the examiner and avoid nosocomial infection, as shown in the application publication number Apply for a patent for the invention of CN111202544A; however, if you want the umbrella-shaped isolation cover to play a sufficient isolation and protection effect, the larger the area of ​​the umbrella-shaped isolation cover, the better, and at least it must be larger than the mouth of the subject after opening his mouth. Therefore, if the umbrella-shaped isolation cover is designed as a disposable appliance integrated with the swab, it will seriously reduce the amount of transportation and storage of testing materials, which is not conducive to the testing work; When the glove part is not careful during operation, it will touch the oral tissue of the examinee. When the next examinee is tested, cross-contamination is extremely easy to occur, increasing the risk of infection for healthy examinees
