A protective cover 114 is arranged at the position of the mouth exhalation hole 112 at the outer side of the headrest 1, and the protective cover 114 is consistent with the curve at the outer side of the headrest 1; when the mouth exhalation port 112 is not in use, the protective cover 114 blocks the mouth exhalation port, and when the mouth exhalation port is in use, the protective cover 114 is opened, so that the inside of the mouth exhalation port 112 is kept clean.
The upper end activity of 1 body of headrest sets up the flexible layer of guaranteeing that patient's face does not receive the extrusion.
And a sterile dressing layer which can effectively prevent cross infection among different patients is laid on the flexible layer.
A neck pillow 6 for protecting the neck of the patient is further arranged on one side, away from the second headrest 14, of the first headrest 13, and the neck pillow 6 is sleeved outside the rotatable fixing rod 2 and is not connected with the first headrest 13; this arrangement is suitable for patients with a long neck portion.
The lateral length of the shoulder pad is as wide as the width of the operating table, so that the patient can observe the angle scale 35 conveniently.
The above description of the embodiments is only intended to illustrate the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications can be made to the present invention, and these modifications will fall within the protection scope of the claims of the present invention.
