after the examination of a patient is finished, medical staff starts the electric telescopic rod 3, the electric telescopic rod 3 is retracted to pull the supporting rod 4 to move downwards, the supporting rod 4 drives the post teeth 8 to move downwards when descending, the post teeth 8 can drive the single-stage flywheel 11 to rotate forwards when moving downwards, the single-stage flywheel 11 rotates the core in the single-stage flywheel 11, the core in the single-stage flywheel 11 drives the transmission rod 10 to rotate together, the transmission rod 10 rotates to drive the plastic film roller 14 in the left supporting column 9 to rotate, the left plastic film roller 14 rotates to wind the plastic film contacted with the patient on the mandibular belt 13, and the clean plastic film on the right plastic film roller 14 is pulled to the upper surface of the mandibular belt 13, so that the replacement of the plastic film is finished, the probability that in the prior art, the medical staff needs to repeatedly replace fixed positions for different instruments and needs to repeatedly disinfect the base for supporting the chin of the patient when examining different patients is greatly increased.
As shown in fig. 1 and 2, the lower end surface of the supporting plate 5 is slidably connected with the upper end surface of the supporting rod 4;
Further, when the patient places the head on the mandibular belt 13, the angle between the patient's eyes and the sensing device of the instrument will deviate, so that the medical staff needs to inform the patient and continuously adjust the angle between the patient's eyes and the sensing device of the instrument, the time required by the examination of the patient is greatly increased, and the design of sliding connection between the lower end surface of the supporting plate 5 and the upper end surface of the supporting rod 4 enables the medical staff to freely pull the supporting plate 5, so that the sensing device of the unilateral adjustment instrument and the patient's eyes reach a proper angle, and the efficiency of the ophthalmic examination of the patient and the accuracy of the examination result are increased.
As shown in fig. 1 and 2, alcohol cotton 22 is fixedly connected to the inner walls of the upper and lower sides of the strip hole 12;
The upper end surface of the mandibular belt 13 is fixedly connected with a cotton block 23, and a gap is reserved between the cotton block 23 and the mandibular belt 13 and is used as an access passage of a plastic film;
Further, clean plastic film is pulled out from the plastic film roller 14 on the right side, when the plastic film is pulled through the strip hole 12 on the right side, alcohol cotton 22 arranged on the inner wall of the strip hole 12 is pulled out from the upper and lower sides, the plastic film is wiped and disinfected by alcohol when passing through, so that the checking environment of a patient is further ensured, and a cotton block 23 on the mandibular belt 13 is sleeved on the mandibular belt 13 by passing through a gap between the cotton block 23 and the mandibular belt 13, the cotton block 23 can play a role in fixing the plastic film, the plastic film can be prevented from being tightly stretched by the plastic film when the plastic film roller 14 pulls the plastic film, so that the plastic film cannot be attached to the surface of the mandibular belt 13, and the problem that medical staff is required to adjust the plastic film is solved.
As shown in fig. 2, an auxiliary rod 21 is rotatably connected to the inner wall of the hollow part of the support column 9, and the auxiliary rod 21 is parallel to the strip hole 12;
Further, the auxiliary rod 21 can prevent the plastic film roller 14 on the left side from being scratched by the outer wall of the lower opening of the strip hole 12 due to the fact that the plastic film roller 14 is arranged below the strip hole 12 when the plastic film is fed into and discharged from the strip hole 12, and the plastic film is attached to the outer wall of the lower opening of the strip hole 12 due to excessive friction between the plastic film and the outer wall of the lower opening of the strip hole 12, so that the plastic film is scratched by the outer wall of the lower opening of the strip hole 12, and the rotating auxiliary rod 21 can not scratch the outer wall of the plastic film and has a supporting effect on the plastic film, so that the plastic film can not be contacted with the inner wall of the opening of the strip hole 12.
As shown in fig. 1 and 2, two ends of the clamping belt 6 are slidably connected with the upper end surface of the supporting plate 5;
Further, because the kinds of the ophthalmic examining instruments are different, the whole sizes of the ophthalmic examining instruments are different, when medical staff replace and fix the ophthalmic examining instruments with different sizes, the positions of the clamping bands 6 on the supporting plate 5 can be adjusted by sliding the positions of the clamping bands 6 to tighten the positions of the ophthalmic examining instruments, so that the ophthalmic examining instruments can be better and firmly fixed, fragile parts of the instruments are prevented from being clamped by the clamping bands 6, and the ophthalmic examining instruments are damaged or the sensing devices on the ophthalmic examining instruments are shielded.
As shown in fig. 1 and 2, the bottom of the machine body 1 is fixedly connected with a lifting base 25;
Further, because the height of the person to be checked is different, the person with high height needs to squat down or bend down to place the chin on the mandibular belt 13 when using the device, while the person with low height needs to stand on standing or needs auxiliary equipment to place the chin on the mandibular belt 13, so that the height of the whole device can be freely adjusted by the lifting base 25 fixedly connected to the bottom of the machine body 1, and the comfort level and the detection smoothness of the patient can be ensured when the patient with different heights is detected.
In the second embodiment, as shown in fig. 5, a pressure valve 26 is fixedly connected to the annular wall of the piston rod 19;
In this example, the difference between the first embodiment and the second embodiment is that the head circumference of each person is different, because the piston rod 19 is extended by internal inflation, and the gas delivered to the interior of the piston rod 19 by the piston tube 18 is substantially uniform each time, so that when the piston rod 19 clamps a patient with a large head circumference, the piston rod 19 stops extending, but the gas continues to be delivered to the interior of the piston tube 18, which causes the pressure in the interior of the piston rod 19 to increase, so that the force of clamping the piston rod 19 to the head of the patient increases, thereby causing discomfort to the patient, and the pressure valve 26 is arranged to cause the piston rod 19 to stop moving, the piston tube 18 continues to deliver the gas to the interior of the piston rod 19, and when the pressure in the interior of the piston rod 19 reaches a certain value, the gas in the interior of the piston rod 19 is discharged from the pressure valve 26, so that the pressure in the interior of the piston rod 19 does not excessively clamp the head of the patient, thereby causing discomfort to the patient.
In the third embodiment, as shown in fig. 1 and 2, the piston rod 19 is vertically and slidably connected with the outer wall of the support column 9;
The difference between this embodiment and the second embodiment is that when an ophthalmic examination is required for a patient with a head injury, a medical staff can adjust the height of the piston rod 19 by vertically sliding the piston rod 19 up and down, so as to adjust the soft ring pad 20 to avoid the wound position of the patient and to fit the head of the patient, thereby preventing the soft ring pad 20 on the piston rod 19 from being clamped to the wound of the patient and causing secondary infection of the wound of the patient when the patient is fixed.
