Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
The device is shown in figures 1 to 4 and comprises a shell 1 with a backward opening, binding belts 2 are respectively arranged at the left end and the right end of the shell 1, an upper axial air outlet pipe 3 and a lower axial air outlet pipe 3 are arranged at the lower end of the shell 1, a plurality of air vents 4 which are distributed along the inner surface of the shell 1 and are in the front-back axial direction are formed in the shell 1, an incomplete gear 5 which is in the front-back axial direction and is rotatable is arranged in front of the shell 1, a rotating shaft 6 which is located above the incomplete gear 5 and is in the front-back axial direction is rotatably connected to the front end of the shell 1, an auxiliary gear 7 which can be meshed with the incomplete gear 5 is coaxially arranged on the rotating shaft 6, a rotating wheel 8 which is located behind the auxiliary gear 7 is coaxially arranged on the rotating shaft 6, and a plurality of fan wheels 9 which are distributed along the circumferential direction are arranged on the outer edge surface of the rotating wheel 8.
In order to increase the binding effect of the binding belt 2, the front surface of the left binding belt 2 is provided with a first magic tape 10, and the rear surface of the right binding belt 2 is provided with a second magic tape 11 which can be adhered to the first magic tape 10.
In order to make the incomplete gear 5 rotatable, the front end of the shell 1 is provided with a front-back axial motor 12, and the output end of the motor 12 is coaxially connected with the incomplete gear 5.
In order to avoid the clamping injury of the patient or the medical staff, the front end of the shell 1 is provided with a protective shell 13 for shielding the incomplete gear 5 and the pinion 7.
In order to control the air flow direction, an air inlet pipe 14 in the vertical axial direction is arranged at the upper end of the protective shell 13, and a check valve 15 with an opening facing the motor 12 is arranged in the air inlet pipe 14.
In order to increase the comfort and the sealing performance of the patient, the rear end of the shell 1 is provided with a rubber strip 16 which has the same shape as the rear end of the shell.
When the utility model is used, when medical personnel need to carry out ophthalmologic operation on a patient, the shell 1 covers the mouth and the nose of the patient, the rubber strip 16 is contacted with the face of the patient, the constraint belt 2 is tightly attached to the head of the patient, and the first magic tape 10 is bonded with the second magic tape 11, so that the shell 1 and the head of the patient are tightly fixed;
at the moment, the medical staff turns on the motor 12, the motor 12 drives the incomplete gear 5 to rotate anticlockwise, the incomplete gear 5 rotates anticlockwise for a certain angle and then is meshed with the pinion 7 and drives the pinion 7 to rotate clockwise, the pinion 7 drives the rotating shaft 6 to rotate clockwise, the rotating shaft 6 drives the rotating wheel 8 to rotate clockwise, the rotating wheel 8 drives the fan wheel 9 to rotate clockwise, after the incomplete gear rotates for a certain angle, wind generated by the fan wheel 9 enters the shell 1 through the air holes 4, refreshing of the mouth and nose of a patient is achieved, and the phenomenon that the mouth, the nose and the face of the patient are wet due to long-time breathing is prevented, so that the discomfort of the patient is caused, and the operation process is influenced;
