The implementation principle is as follows: when the eyes of the patient are washed, the spherical rotating seat 22 in the eyelid opening device is firstly installed on the connecting component 13 of the left cover body 11 or the right cover body 12, and the negative pressure pipe 42 is connected to the connecting pipe 18 of the left cover body 11 or the right cover body 12 which is provided with the eyelid opening device; then the left cover body 11 or the right cover body 12 provided with the eyelid opening device is abutted against the cheek of the patient, at the moment, the opening angle of the two supporting arms 23 is adjusted by adjusting the distance between the two handles 25 in the eyelid opening device, the eyelid of the patient is opened through the eyelid opening piece 24, and the eyelid can be opened by adapting to different patients through the rotary motion of the spherical rotating seat 22 in the connecting component 13 in the process; then the eye washing liquid in the liquid medicine tank 31 enters the drainage tube 32 and the universal tube 33 at a certain pressure through the pressure adjusting mechanism 36 and is sprayed out from the washing spray head 34, so that the eyes of the patient are washed; finally, the waste washing liquid of the left cover body 11 or the right cover body 12 is recovered through a waste liquid negative pressure recovery device.

In the connecting assembly 13, the first connecting seat 131 and the second connecting seat 132 are matched to allow the spherical rotating seat 22 in the eyelid retractor to rotate; and the first connecting seat 131 is in threaded connection with the second connecting seat 132, and the second connecting seat 132 is provided with a notch 1321 for the support 21 near the spherical rotating seat 22 to pass through, so that the second connecting seat 132 is conveniently in threaded connection with the first connecting seat 131, and the eyelid opening device is conveniently assembled and disassembled on the connecting component 13.

Because the connecting ring 15 on the peripheral side of the first connecting seat 131 is made of the material of silica gel, when the connecting ring 15 is used for pressing the first connecting seat 131, the connecting ring 15 is deformed under stress, so that the relative position between the first connecting seat 131 and the left cover body 11 or between the first connecting seat 131 and the right cover body 12 is changed, the installation position of the eyelid retractor is changed, and the eyelid can be opened by more patients.

When the patient fixes the left cover body 11 or the right cover body 12 through the elastic bandage 17, medical staff does not need to fix the left cover body 11 or the right cover body 12 at the moment; however, if the face is burned with a large area, the elastic bandage 17 is pressed against the burned part to cause pain to the patient, and the elastic bandage 17 needs to be detached to fix the left cover body 11 or the right cover body 12 by the medical staff.

Because the eyes are often burnt along with the eyelids, the skin of the patient after scabbing at the eyelids is fragile, the eyelid opening part 24 comprises an iron pick 241 and a silica gel buffer pad 242, so that the silica gel buffer pad 242 directly contacts the eyelids of the patient, and the buffering effect is achieved when the eyelids are opened.

The eye rinsing liquid discharged from the liquid medicine tank 31 is pressurized by the pressurizing pump 361, and the water pressure when the eye rinsing liquid is discharged from the first valve 362 is adjusted by adjusting the flow pipe diameter of the first valve 362, and finally the pressure is detected by the pressure gauge 363, so that the eye rinsing liquid can rinse the eyes of the patient with a proper pressure.

In-process that the eye flush fluid transported from transfer line 35, the eye flush fluid in to transfer line 35 heats through heating device to make the temperature of eye flush fluid rise, make the temperature of eye flush fluid rise to the degree that matches with the temperature of eyes, thereby can improve the comfort level when eye flush fluid washes eyes.

The left cover body 11 and the right cover body 12 are symmetrically provided with two connecting pipes 18, when a patient lies on a hospital bed to wash eyes, the waste liquid negative pressure recovery device is connected with the connecting pipes 18 which are far away from the left cover body 11 or the right cover body 12, so that the washed waste liquid flows down from the side surface of a cheek and is recovered by the waste liquid negative pressure recovery device; and because the hospital often meets the condition that the bed is not enough, the patient is not easy to wash the eyes after lying down, at the moment, the waste liquid negative pressure recovery device is connected with the connecting pipe 18 at the middle part of one side of the left cover body 11 or the right cover body 12 close to the nose of the patient, and at the moment, the patient can wash the eyes in the standing or sitting condition.

Example 2: a binocular washer, as shown in fig. 5, is different from the embodiment in that: the liquid medicine tank 31 comprises a cylinder 311 for containing eye washing liquid and a piston 312 telescopically arranged in the cylinder 311, and the cylinder 311 is provided with a liquid outlet end connected with the liquid conveying pipe 35. The pressure adjusting mechanism 36 includes a base 364, a clamping assembly 365 disposed on the base 364 for fixing the barrel 311, a telescopic cylinder 366 mounted on the base 364, a pushing block 367 mounted on the telescopic cylinder 366 for pushing the piston 312, and a second valve 368 mounted between the drainage tube 32 and the infusion tube 35. The clamping assembly 365 includes an arc-shaped pad 3651 fixedly disposed on the base 364 and for the cylinder 311 to be inserted, an arc-shaped pressing block 3652 abutting against the periphery of the cylinder 311, and a locking bolt 3653 connected between the arc-shaped pressing block 3652 and the arc-shaped pad 3651.

The implementation principle is as follows: the cylinder body 311 of the liquid medicine tank 31 is fixed on the base 364 through the clamping component 365, and then the piston 312 is driven to move through the push block 367 on the cylinder, so that the eye flushing liquid is discharged at a certain pressure, and the second valve 368 is used for opening and closing the liquid conveying pipe 35; at this time, for the binocular washer of the same size, the pressure of the eye rinsing liquid sprayed from the irrigation nozzle 34 can be determined in advance by the pushing speed of the pushing block 367 on the cylinder, so that the eye rinsing liquid can rinse the eyes of the patient at a proper pressure.
