By arranging the moving mechanism, the position of the non-contact ophthalmologic instrument 7 and the position of the contact ophthalmologic instrument 8 can be adjusted by a doctor only by controlling one hand crank 42, a great amount of time is saved, and the complex operation of the doctor is avoided.
When the first rack 2 synchronously and transversely slides to adjust the position, the connecting block 52 fixedly connected with the first rack 2 synchronously and reciprocally slides at the same time, so that the first sealing plug 56 and the first piston rod 51 synchronously slide and reciprocally slide along the inner wall of the first piston cylinder 5, and further the pressure in the first piston cylinder 5 repeatedly changes, which is described in detail as follows:
in the above, when the first piston rod 51 and the first sealing plug 56 slide in the first piston cylinder 5 toward the end far from the liquid inlet pipe 53, negative pressure is generated under the cooperation of the check valve 55, so that the anesthetic agent of the external drug supply mechanism is sucked into the first piston cylinder 5 through the liquid inlet pipe 53, and when the first piston rod 51 and the first sealing plug 56 slide in the first piston cylinder 5 toward the end near to the liquid inlet pipe 53, high pressure is generated under the cooperation of the check valve 55, so that the anesthetic agent in the first piston cylinder 5 is sent into the second piston cylinder 6 through the infusion pipe 54, and the effect of automatically supplementing the anesthetic agent into the second piston cylinder 6 is achieved.
The drug delivery mechanism is an existing device and is not described in detail herein nor shown in the figures.
When the screw rod 46 axially slides while rotating, at the same time, the connecting rod 31 drives the abutting plate 47 to synchronously slide in the direction away from the rotating shaft 41, so that the abutting block 62 abutting against the abutting plate 47 synchronously slides in the direction away from the rotating shaft 41, and then the second piston rod 61 drives the second sealing plug 66 and the third sealing plug 67 to synchronously slide in the direction away from the rotating shaft 41, so that the anesthetic agent sent to the second piston cylinder 6 by the infusion tube 54 is dripped into the eyeball of a patient under the cooperation of the one-way valve 55 through the cooperation of the liquid discharge tube 65 and the dripper 74, and the effect of automatically dripping the anesthetic agent to the eyeball of the patient before detection is achieved.
After the liquid discharge pipe 65 and the dripper 74 drip the anesthetic agent to the eyeball of the patient, at this time, the second sealing plug 66 is in contact with the sliding plate 72 and drives the sliding plate 72 to slide away from the rotating shaft 41 until the opening on the sliding plate 72 coincides with the exhaust pipe 64, so that a small amount of gas is blown out through the exhaust pipe 64 and the nozzle 69 under the cooperation of the one-way valve 55, the anesthetic agent dripped on the eyeball of the patient is dispersed successfully, the dispersing speed of the anesthetic agent is accelerated, and when the gas is blown, the patient is blown by the gas, the eye is blinked, and the dispersing speed of the anesthetic agent is accelerated, then when the contact ophthalmologist 8 continues to move, the doctor performs preliminary observation on the eyeball of the patient through the non-contact ophthalmologist 7 until the contact ophthalmologist 8 contacts the eyeball of the patient, and then the doctor observes and analyzes, and the cause of the patient is determined more accurately.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
