Furthermore, the positioning air bag also comprises an auxiliary pressing bulge positioned in the middle of the annular pressing part.
Further, the inflatable balloon comprises an elastic balloon body, a deflation valve, a first one-way valve and a second one-way valve, one end of the deflation valve is connected with the air pipe, the other end of the deflation valve is connected with the front end of the elastic balloon body, the first one-way valve is connected to the end portion of the deflation valve, the first one-way valve is located in the front end of the elastic balloon body, and the second one-way valve is arranged at the rear end of the elastic balloon body.
The invention has the beneficial effects that:
1. the nuclear magnetic resonance detection eyeball fixer has the advantages that the balloon of the positioning air bag can be adjusted along the bridle, and the nuclear magnetic resonance detection eyeball fixer can adapt to patients with different interpupillary distances. The nuclear magnetic resonance detection eyeball fixator fixes the eyeball through the positioning balloon, the annular pressing part of the positioning balloon can be well attached to the periphery of the eyeball, the pressing force in all directions is uniform, and the eyeball can be well prevented from moving; and the inflation quantity of the positioning saccule can be adjusted by inquiring the feeling of the patient, so that the reliability of eyeball fixation can be ensured, and the discomfort of the patient can be avoided.
2. According to the nuclear magnetic resonance detection eyeball fixer disclosed by the invention, the auxiliary pressing bulge in the middle of the positioning air bag can further improve the reliability of fixing the eyeball.

Detailed Description
The invention is further described below with reference to the figures and examples.
The nuclear magnetic resonance detection eyeball fixator comprises a binding band 1, a positioning air bag 2 for fixing eyeballs, a clamping groove block 3 bonded on the positioning air bag and an inflatable air bag 5 connected with the positioning air bag through an air pipe 4, wherein the clamping groove block penetrates through the binding band and can move along the binding band; the positioning air bag comprises a circular pressing part 21 for pressing the eyeball.
In this embodiment, the inflatable balloon includes an elastic balloon body 51, a deflation valve 52, a first check valve 53 and a second check valve 54, one end of the deflation valve is connected to the air pipe, the other end of the deflation valve is connected to the front end of the elastic balloon body, the first check valve is connected to the end of the deflation valve, the first check valve is located in the front end of the elastic balloon body, and the second check valve is disposed at the rear end of the elastic balloon body. The first one-way valve allows gas within the elastomeric bladder to flow to the positioning bladder but prevents gas within the positioning bladder from flowing to the elastomeric bladder. The second one-way valve allows external air to flow into the elastic bag body, but prevents the air in the elastic bag body from flowing to the outside. When the elastic bag body is extruded, the gas in the elastic bag body enters the positioning air bag to realize the inflation of the positioning air bag; when the elastic bag body is loosened, the elastic bag body rebounds, negative pressure is formed in the elastic bag body, and outside air enters the elastic bag body. When the detection is finished and the gas in the positioning air bag needs to be discharged, the handle 521 on the air discharge valve is rotated, the sealing gasket 522 connected to the lower end of the handle leaves the air inlet hole 523 on the valve body, and the gas is discharged from the air discharge hole 524 on the valve body, so that the air discharge of the positioning air bag is realized.
In the embodiment of the eyeball fixer for nuclear magnetic resonance detection, when the eyeball fixer is used, the belt is firstly bound on the head of a patient in an eye closing state of the patient, and then the position of the positioning air bag is quickly adjusted by moving the clamping groove along the belt, so that the positioning air bag is positioned in the middle of the eyeball; the position of the positioning air bag can be adjusted, so that the positioning air bag can adapt to patients with different interpupillary distances. The positioning air bag is inflated through the inflating air bag, and the feeling of the patient is inquired in the inflating process, so that the discomfort of the patient caused by the overhigh pressure of the positioning air bag is avoided. The positioning saccule exerts pressure on the eyeball through the annular pressure exerting part, the annular pressure exerting part can be well attached to the periphery of the eyeball, the pressure exerting in all directions is uniform, and the eyeball can be well prevented from moving. After the detection is finished, the air in the positioning air bag is released through the air release valve on the air inflation ball bag, and the nuclear magnetic resonance detection eyeball fixer can be conveniently taken down from the head of a patient.
As a modification to the above embodiment, the positioning airbag further includes an auxiliary pressing protrusion 52 located in the middle of the annular pressing portion. The auxiliary pressing bulge is arranged, so that the fixation reliability of the eyeball can be further improved.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
