Has the advantages that: this traditional pharynx swab sampling operation of patent mainly includes: (1) according to the respirator, the nose mask body is provided with the oxygen inhalation port and the vent connected with the filter assembly, so that sampling in a closed space is realized while normal ventilation is realized, and infection sources such as respiratory droplets are isolated; (2) in the main body of the oronasal mask, the oxygen inhalation port can be connected with an oxygen inhalation device, so that a patient can conveniently inhale oxygen in the sampling process, and the oxygen inhalation mask is suitable for patients with hypoxemia or reduced transient oxygen saturation after sampling stimulation by a throat swab; (3) in the nose and mouth mask body, an adjustable inflatable air bag is arranged at the position contacting with the face of a patient, so that the wearing comfort and the tightness are enhanced; (4) the oral-nasal mask body is provided with an annular mouth part extending outwards, and the annular mouth part can be connected with a transparent plastic sealing cover or a sterile rubber plug, and the oral-nasal mask body and the transparent plastic sealing cover or the sterile rubber plug can be disassembled and assembled, so that the oral-nasal mask and the sterile rubber plug can be alternately used, and repeated safe pharynx swab sampling can be realized until the sampling is satisfactory; (5) the detachable rubber plug is provided with auxiliary devices such as a tongue depressor and the like which can be inserted, so that better sampling is facilitated; (6) according to the handle rod at the rear end of the sterile sampling swab, the scratch which is vertically arranged in the long axis direction is arranged at the position 1/3 behind the rod body, the handle rod body can be quickly broken by reversely folding along the scratch, and the phenomenon that preservation solution is oscillated and splashed out due to repeated folding or pathogen aerosol on the sampled swab is overflowed is avoided; (7) the annular oral area of outside extension in this patent oronasal mask main part, diameter 2.5cm can be fit for connecting and do not have the wound breathing machine pipeline, if the proruption of state of an illness changes in the patient's sampling process, but the consecutive lug connection breathing machine rescue treatment.
The utility model has the advantages of safe and sampling whole journey is airtight not have the wound, is applicable to the pharynx swab sampling of the various state patients of disease (the trachea cannula has the wound treatment patient of ventilating) to medical occupation exposes when greatly reduced the sampling, has reduced respiratory infectious disease cross infection's risk.
Referring to fig. 4 and 5, in embodiment 2, on the basis of embodiment 1, a cutting mechanism is installed at the front end of the rubber stopper; the outer diameter of the front end of the rubber plug is smaller than that of the rear end of the rubber plug; the cutting mechanism comprises a fixed shearing knife 71 fixed at the front end of the rubber plug and a rotary shearing knife 72 rotatably connected with the rubber plug; during rotation of the rotary shear knife 72, the orthographic projection of the blade of the rotary shear knife 72 moves from not covering a sampling aperture to covering a sampling aperture. And then realize the cutting to the sampling swab tip, be convenient for break off with the fingers and thumb. The cutting edge of the fixed shearing knife is tangent to all the sampling holes. To facilitate abutting the sampling swab when sheared.
The rotatory sword of cuting includes round rubber buffer pivoted installation section of thick bamboo, and the front end of an installation section of thick bamboo is equipped with cuts the blade, and the rear end of an installation section of thick bamboo is equipped with the arch. The front end of the rubber plug is provided with a guide groove 33 for guiding the protrusion to slide in axially. The front end of the rubber plug is also provided with an annular groove 34 for guiding the protrusion to rotate circumferentially. The guide groove is communicated with the annular groove. The circumferential rotation of the installation cylinder is convenient to realize.
All sampling holes are arranged on the same side of the central axis of the rubber plug. Facilitating the rotary cutting. And the arrangement direction of all sampling holes can be the radial direction of the rubber plug.
The mounting cylinder may be semi-annular. After the sampling of being convenient for was ended, the rubber buffer took off the back, loaded the rotatory sword of cuting and cut.
Or the outer diameter of the mounting cylinder is smaller than the outer diameter of the rear end of the rubber plug. The rotary shearing knife can be conveniently inserted into the annular opening. The sampling hole is opened at a position accessible to the blade of the rotary shearing knife.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
