Abstract

PURPOSE:To prevent the contagion of a pathogenic bacteria due to the search of a probe by providing an electric connecting part in the rear part of the probe, inserting the probe through an ophthalmologic device main body, freely holding the probe and connecting the electric connecting part to the connecting part of the device main body. CONSTITUTION:A probe 1 is put into a germ reducing tank and germ reduction processing is executed to the probe. After that, the probe is inserted to a probe holder 12 and click terminals 14a and 14b of a connector jack 14 are contacted to a connector pin 4. Thus, in a condition that the connector pin 4 and connector jack 14 are fit, they are mechanically held by suitable force and also electrically, they are connected with an electric circuit unit 5. Then, the measurement of an eye shaft length can be executed to a checked eye E by the transmission and an ultrasonic wave from an ultrasonic wave transmitter and receiver 2. Here, since mechanically simple structure is enough for the probe 1, waterproof structure can be easily obtained. Then, it is possible to dip the whole probe 1 in sterilizing liquid or to put the probe into a gas germ reducing tank and the effective germ reduction processing can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ophthalmological device having a probe that is brought into contact with the surface of the cornea of the eye to be examined, such as an ultrasonic axial length measuring device. .

[Prior Art] Conventionally, ophthalmological devices equipped with ultrasonic probes, such as ultrasonic axial length measurement devices, have two methods: one in which the examiner directly holds the probe with his or her child, and the other in which the examiner holds the probe directly with his or her child. -Some devices perform measurements by attaching the probe to a support member placed on a sliding table that can move forward and backward, and these devices are structured so that the probe itself cannot be easily attached or detached from the main body. There is.

However, if the probe cannot be separated from the main body of the device,
When sterilizing a probe, it is only possible to wipe the tip with absorbent cotton soaked in disinfectant, making it difficult to sterilize the probe sufficiently to prevent infection by pathogens. .

[Objective of the Invention] The object of the present invention is to improve the problems of the conventional method and provide a structure in which the probe can be easily attached and detached from the main body of the device, thereby making it possible to remove the probe as a single unit and perform sufficient sterilization. The object of the present invention is to provide an ophthalmological device that can be used.

[Summary of the invention] The gist of the present invention is to achieve the above objects.

In an ophthalmological apparatus that has a rod-shaped probe that is brought into contact with the surface of the cornea of the eye to be examined, and detects information about the eye to be examined by the probe,
The ophthalmological apparatus is characterized in that an electrical connection part is provided at the rear of the probe, and the probe is held so that it can be inserted into and removed from the main body of the apparatus, and the electrical connection part is connected to the connection part of the main body of the apparatus. .

[Embodiments of the invention] The present invention will be explained in detail based on illustrated embodiments.

FIG. 1 is an external view of an ultrasonic probe when the present invention is applied to an ultrasonic axial length measuring device. A matching circuit 3 is housed at the rear end, and a connector pin 4 is provided protruding from the rear end.

FIG. 2 is a schematic diagram showing the entire axial length measuring device incorporating the probe 1, in which a sliding table 7 is installed on a fixed table 6 that houses an electric circuit unit 5.

A probe support base 10 is placed on the top surface of the slide base 7, and is designed to slide back and forth and left and right when the operation stick 8 is operated, and is moved up and down by the rotation of a dial 9 provided at the base of the operation stick 8. has been done. A guide rod 11 is fixed to this probe support base 10, and a probe holder 12 is slidable in the front and back direction along the guide rod 11, and is further biased forward by a weak spring 13. . A probe l is inserted into the probe holder 12, and a connector having click terminals 14a and 14b that fits into the connector pin 4 of the probe 1 is provided at the back of the probe holder 12. A jack 14 is attached, and the connector jack 14 is connected to the electric circuit unit 5 by a cable 15. Further, a measurement data display 16 is provided on the rear surface of the sliding table 7, and a face support section 17 for the subject is provided on the fixed table 6.

When using the axial length measuring device configured as described above, first sterilize the probe 1 by placing it in a sterilization tank, etc., then insert it into the probe holder 12, and then insert it into the connector jack 14.
The click terminals 14a and 14b of the connector pin 4 are brought into contact with the connector pin 4.

As a result, the connector bin 4 and the connector jack 14 are mechanically held in a fitted state with appropriate force, and are also electrically connected to the electric circuit unit 5, so that the ultrasonic wave from the ultrasonic transmitter/receiver 2 By transmitting and receiving, the axial length of the eye E to be examined can be measured with the same operations as in the conventional device.

The probe l shown in Figure 1 has a mechanically simple structure, so it is easy to make it waterproof, and the entire probe l can be immersed in a disinfectant solution or placed in a gas sterilization tank. This makes it possible to carry out effective sterilization.

In addition, when measuring multiple subjects in succession, preparing multiple probes 1 and changing the probe 1 for each subject while sterilizing them in turn increases efficiency. measurements can be carried out.

[Effects of the Invention] As explained above, the ophthalmological apparatus according to the present invention enables effective and effective sterilization of the probe by making the probe that contacts the subject's eye mechanically and electrically removable. Since it is easy to perform, it is effective in preventing infection by pathogenic bacteria due to contact with the probe.
