To achieve these goals, the technical solution adopted by the present invention is：A kind of adaptive air-cushion type head fixing device,
Including air releasing device, aerating device, single-chip microcomputer, charge and discharge air cock, pressure sensor, relay and for placing fixed patient's head
The U-shaped pillow in portion；The air bag that can be charged and discharged gas built in the U-shaped pillow, the single-chip microcomputer connects aerating device by relay, described
Aerating device connects air bag, and the charge and discharge air cock connects single-chip microcomputer, and charge and discharge air cock opens single-chip microcomputer control relay and obtains electric,
Aerating device makes U-shaped pillow step up patient head to airbag aeration；The pressure sensor is connected with air bag, and air bag is monitored in real time
Interior pressure, pressure signal transmission to single-chip microcomputer is compared with default pressure value, and intracapsular pressure is equal to default pressure
Aerating device stops inflation during value；The air releasing device connects air bag.
Of the invention further, the air bag is rubber pneumatic bag, and air bag and outer U pillow both sides are provided with ear groove.Patient's head
Portion is lain in U-shaped pillow, while clamping head to airbag aeration, and certain compressing can be caused to ear, in order to improve comfort, is kept away
Exempt to cause ear compressing, therefore ear groove is provided with U-shaped pillow both sides, ear groove is exposed at U-shaped pillow outer, it is ensured that comfort level.
Of the invention further, the ear groove is U-shaped, and ear groove circular arc portion is the semicircle groove that radius is 5 centimetres, at this
Under preferred size, a preferably comfort level can be reached.
Of the invention further, the pump-up device is inflator pump.
Of the invention further, the air releasing device is the magnetic valve that loses heart.
Of the invention further, the scheduled pressure value is 70mmHg, and the pressure value ensure that in fixed patient head
While, it is ensured that the comfort level of patient head.
Patient head is put into the U-shaped of unaerated headrest by the present invention, presses charge and discharge air cock, and air releasing device is closed, filled
Device of air is started working, after the pressure value for reaching and being set in single-chip microcomputer is inflated, and aerating device stops inflating, and patient head is solid
It is fixed, start CT examination, after inspection is finished, press charge and discharge air cock, air releasing device is opened, air bag release pressure loosens patient's head
Portion, whole operation process is using the control automated.It ensure that patients head can not rock or mobile during CT examination, from
And ensure CT image clearlies, diagnosis is accurate, while take into account the comfort of patients head, it is convenient, stably, comfortably, accurately, it is economical.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, a kind of adaptive air-cushion type head fixing device of the present invention, including air releasing device, inflation dress
Put, single-chip microcomputer 6, charge and discharge air cock 7, pressure sensor 8, relay 9 and for place fixed patient head U-shaped rest the head on 10；Its
In middle the present embodiment, air releasing device is the magnetic valve 2 that loses heart, and aerating device is inflator pump 3.First can inflation/deflation built in U-shaped pillow 10
The air bag 11 of body, single-chip microcomputer 6 connects inflator pump 3 by air driven pump drive circuit 4, relay 9, and the connection air bag 11 of inflator pump 3 fills
Air escape cock 7 connects single-chip microcomputer 6, and charge and discharge air cock 7 opens the control relay of single-chip microcomputer 6 and obtains electric, and inflator pump 3 fills to air bag 11
Gas, makes U-shaped rest the head on 10 and steps up patient head；Pressure sensor 8 is connected with air bag 11, and intracapsular pressure, pressure sensing are monitored in real time
Device 8 connects single-chip microcomputer 6 by pressure signal amplifying circuit, and pressure signal transmission to single-chip microcomputer 6 and default pressure value are carried out
Compare, inflator pump 3 stops inflation when pressure is equal to default pressure value in air bag 11；Single-chip microcomputer 6 passes through driving circuit for electromagnetic valve 5
The discouraged magnetic valve 2 of connection, lose heart the connection air bag 11 of magnetic valve 2.
On the basis of said structure, air bag of the present invention uses rubber pneumatic bag, as shown in figure 3, air bag 11 and outer U pillow 10
Both sides are provided with ear groove 11-1.Ear groove 11-1 is U-shaped, and ear groove circular arc portion is the semicircle groove that radius is 5 centimetres.
Operation principle of the present invention is as follows：Pressure sensor 8 is set in initial state, single-chip microcomputer 6, patient head is put
Enter U-shaped headrest, press charge and discharge air cock 7, the adhesive of 6 control relay of single-chip microcomputer 9 inflates pump startup, now the gas in air bag 11
Body is on the increase, and by four-way connection, now pressure in the real-time monitoring air bag 11 of pressure sensor 8, reaches our default pressures
Stop inflating after force value, now patient head has been completely fixed, CT examination can be carried out, after inspection terminates, inflation/deflation is pressed
Switch 7 is resetted, and the control magnetic valve 2 of single-chip microcomputer 6 is opened, and air bag 11 is lost heart, and patient, which checks, to terminate, and reaches that we fix patient's head
The purpose of portion position.Wherein scheduled pressure value is 70mmHg, and the pressure value enough ensures while fixed patient head, it is ensured that
The comfort level of patient head.
Certainly, above-described embodiment is only the preferred scheme of the present invention, is specifically not limited thereto, on this basis can basis
It is actually needed and makes with targetedly adjusting, so as to obtain different embodiments.Because mode in the cards is more, this
In just no longer illustrate one by one.
