Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 6 and give, axial cap body 1 about including, the 1 left and right sides of cap body sliding connection has the cardboard 2 of J-shaped respectively, two 2 bilateral symmetry of cardboard, 1 upper end of cap body is coaxial to be equipped with rotates box 3, coaxial rotation is connected with pivot 4 in rotating box 3, the 4 left and right sides of pivot are connected with its cardboard 2 that correspond the side through stay cord 5 respectively, coaxial ratchet 6 that is located to rotate box 3 is equipped with in the pivot 4, it can be with ratchet 6 complex pawl 7 to rotate 3 internal rotation of box, it is equipped with a plurality of scale marks 8 along its circumferencial direction equipartition to rotate 3 upper ends of box, be equipped with the marker post 9 that corresponds with scale mark 8 in the pivot 4.

In order to carry out spacingly to two

cardboard

2, 2 lower extremes of cardboard on left be equipped with opening fixture block 10 to the right, 2 lower extremes of cardboard on right side are equipped with the elastic block 11 that can insert in fixture block 10.

In order to facilitate the sliding of the clamping plate 2, the left side and the right side of the cap body 1 are respectively provided with a yielding groove with a downward opening, the front side wall and the rear side wall of the yielding groove are respectively provided with a sliding groove, and the front side and the rear side of the clamping plate 2 are respectively provided with a clamping column 12 inserted into the sliding groove.

In order to facilitate the rotation of the rotating shaft 4, the left side and the right side of the rotating shaft 4 are respectively and fixedly connected with an auxiliary block 13 positioned above the rotating box 3.

In order to facilitate releasing the limit of the pawl 7, an arc-shaped swing groove 14 is formed in the rotating box 3, and an auxiliary rod 15 extending out of the swing groove 14 is arranged on the pawl 7.

In order to improve the comfort of the patient, a cushion 16 is provided on the inner surface of the clamping plate 2.

When the utility model is used, the medical staff pulls the elastic block 11 out of the clamping block 10 and puts the head of the patient in the cap body 1, when the head of the patient is positioned in the cap body 1, the medical staff inserts the elastic block 11 into the clamping block 10, and the face of the patient is contacted with the soft cushion 16;

when the face of a patient is contacted with the cushion 16, a medical worker holds the auxiliary block 13 and rotates the auxiliary block 13 clockwise, the auxiliary block 13 drives the rotating shaft 4 to rotate clockwise, the rotating shaft 4 drives the clamping plate 2 to move upwards through the pull rope 5, the rotating shaft 4 synchronously drives the ratchet 6 to rotate clockwise, the ratchet 6 cannot rotate anticlockwise under the action of the pawl 7, the clamping plate 2 is gradually and completely attached to the face of the patient, the jaw bone of the patient is completely fixed at the moment, and the medical worker records the numerical value of the scale mark 8 on the identification rod 9;

after the patient recovers for a period of time, the medical staff rotates the auxiliary block 13 according to the actual situation, so that the clamping plate 2 can keep the clamping property on the jaw bone of the patient;

after the patient is completely recovered, the medical staff swings the auxiliary rod 15 rightwards to enable the pawl 7 to be separated from the ratchet wheel 6, the rotating shaft 4 rotates anticlockwise under the action of the clamping plate 2 and the pull rope 5 to relieve the limitation on the face of the patient, and the elastic block 11 is pulled out of the clamping block 10 by the medical staff, so that the device is separated from the face of the patient.

The utility model discloses simple structure, convenient operation conceives the novelty, and the practicality is strong, and medical staff only needs to rotate the pivot and just can adjust the power that resets that this device produced, and under the effect of ratchet and pawl, two cardboards can be long-time keep carrying out the clamping state to patient's face, and the adjustment of counter shaft every time can all make cardboard and patient's face laminate more to the assurance can not lead to the cardboard to relax and drop because of the affected part healing.
