After the adjustment of the longitudinal and transverse positions of the non-contact ophthalmoscope 7 and the contact ophthalmoscope 8 is completed, the physician pushes the hand crank 42 towards the clamping rotating shaft 41, so that the gear 43 is not engaged with the first rack 2 and the second rack 3, and because the screw rod 46 is connected in the placing groove 22 in a limiting and sliding manner, when the rotating shaft 41 slides, the screw rod 46 slides relatively in the placing groove 22, when the rotating shaft 41 slides towards the resisting plate 47, the first ring 17 drives the first supporting rod 15 to slide towards the resisting plate 47, so that the ball 16 slides towards the resisting plate 47 along the inclined sliding groove of the sliding block 14, the sliding block 14 further slides towards the screw rod 46 until the sliding block 14 is matched with the spiral groove on the screw rod 46, and then the physician shakes the hand crank 42, so that the screw rod 46 slides axially while rotating, and the contact ophthalmoscope 8 slowly slides until the contact eyeball of the patient, the contact ophthalmoscope 8 then transmits the intraocular pressure value to a computer connected to the contact ophthalmoscope 8, which the physician then analyzes to determine the cause of the patient.
Through setting up moving mechanism, reached the doctor and only need can accomplish the regulation to non-contact ophthalmology ware 7 and contact ophthalmology ware 8 position through controlling a crank 42, saved a large amount of time, avoided doctor's complex operation.
When the first rack 2 is slid laterally and synchronously to adjust the position, at the same time, the connecting block 52 fixedly connected with the first rack 2 slides reciprocally and synchronously, so that the first sealing plug 56 and the first piston rod 51 slide reciprocally and synchronously along the inner wall of the first piston cylinder 5, and the pressure in the first piston cylinder 5 changes repeatedly, as described in detail below:
in the above, when the first piston rod 51 and the first sealing plug 56 slide in the first piston cylinder 5 to the end far from the liquid inlet pipe 53, a negative pressure is generated by the cooperation of the check valve 55, so that the anesthetic of the external medicine 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 to the end near the liquid inlet pipe 53, a high pressure is generated by the cooperation of the check valve 55, so that the anesthetic in the first piston cylinder 5 is delivered into the second piston cylinder 6 through the infusion tube 54, and an effect of automatically replenishing anesthetic into the second piston cylinder 6 is achieved.
The drug supply mechanism is a conventional device, and therefore, it is not described in detail here and is not shown in the drawings.
When the screw rod 46 axially slides while rotating, meanwhile, 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 abutted 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 delivered to the second piston cylinder 6 by the infusion tube 54 is delivered to the eyeball of the patient under the cooperation of the one-way valve 55 and the liquid discharge tube 65 and the dropper 74, and the anesthetic liquid is dripped into the eyeball of the patient, so that the effect of automatically dripping the anesthetic on the eyeball of the patient before detection is achieved.
After the drainage tube 65 and the dropper 74 have dripped the anesthetic into the patient's eye, the second sealing plug 66 contacts the sliding plate 72, and drives the sliding plate 72 to slide in the direction away from the rotating shaft 41 until the opening on the sliding plate 72 coincides with the exhaust pipe 64, so that the gas is discharged through the check valve 55, a small amount of gas is blown out through the exhaust pipe 64 and the nozzle 69, so that the anesthetic dropped on the eyeball of the patient is successfully dispersed, the dispersion speed of the anesthetic is accelerated, and when the gas is blown, the patient is blown by the gas, the eyes can blink, meanwhile, the dispersion speed of the anesthetic is increased, then when the contact-type ophthalmoscope 8 continues to move, a doctor initially observes the eyeball of the patient through the non-contact-type ophthalmoscope 7 until the contact-type ophthalmoscope 8 is in contact with the eyeball of the patient, and then the doctor observes and analyzes the contact-type ophthalmoscope to determine the cause of the patient more accurately.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
