In this embodiment, the cleaning sleeve 41 is provided with an ultraviolet lamp control switch 412 and a water inlet switch 411, the ultraviolet lamp control switch 412 is electrically connected with the ultraviolet lamp 42, and the water inlet switch 411 is electrically connected with a water pump; when the cleaning device is used, the water pump pumps external water into the water pipe, and the external water is sprayed into the cleaning sleeve 41 through the spray head 43, so that the collection mechanism in the accommodating cavity is cleaned, and meanwhile, ultraviolet rays and the like are turned on, so that the collection mechanism in the accommodating cavity can be disinfected.
When the medical cleaning device is used, medical staff holds the handle, and the cleaning mechanism is used for cleaning and disinfecting the collection mechanism in the accommodating cavity in the state that the cleaning sleeve is buckled with the handle. After cleaning, the cleaning sleeve is pulled out of the handle, the collecting mechanism is exposed, the clamping switch on the control mechanism is pressed down, the clamping jaw of the clamping unit is opened, the tail part of the sampling rod is placed into the clamping unit, the clamping switch is pressed down again, and the clamping jaw of the clamping unit is contracted to finish the operation of clamping the cotton swabs. Medical personnel stretch into in the patient's oral cavity with collection mechanism, let the patient bite the interlock platform, but the setting of isolation part large tracts of land shelters from patient's oral cavity reduces and avoids even that patient's respiratory tract gas directly spouts medical personnel. The medical staff presses down the swing switch, the tongue depressor presses down the root of the tongue of the patient, at the moment, the camera control switch and the light source control switch are pressed down to start the light source and the camera, and the positions of the sampling rod and the tongue depressor are observed through the display screen; and then the telescopic switch is pressed down to control the length of the sampling rod extending into the oral cavity of the patient. After determining the target position of the ulcer surface or the infection site and the like in the oral cavity of the patient, the sampling rod is controlled to extract secretion of the ulcer surface, the infection site or the target site of the oral cavity of the patient. After pharyngeal secretion is collected and extracted, the sampling rod is controlled to leave the oral cavity contact surface of the patient through the telescopic switch, the tongue depressor is lifted through the control swing switch, the patient is informed to release the occlusion table, the hand-held part is held to enable the patient to withdraw from the mouth of the patient, finally, medical staff presses the clamping switch to take the sampling rod, and then the sampling rod is placed in the prepared sampling liquid to complete sampling operation.
Compared with the prior art, the invention provides the pharyngeal secretion collecting device, by designing the occlusion table, the teeth of a patient can bite on the occlusion table, so that the mouth of the patient is in a closed state, the possibility of virus transmission in the spray of the patient is reduced, and the risk of virus infection of medical staff is also reduced; according to the invention, the tongue pressing assembly is designed to press the tongue root, so that the tongue of a patient is prevented from being tilted, and then the sampling assembly is used for sampling the throat part of the patient, so that the sampling difficulty is reduced; meanwhile, the invention designs an auxiliary observation assembly, and the images of the sampling rod and the tongue depressor in the oral cavity are acquired in real time by using the camera, so that medical staff can observe the state in the oral cavity and the position of the pharyngeal portion of a patient, and further accurate sampling is realized.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
