JPH02104329A - Image recording device for endoscope - Google Patents

Abstract

PURPOSE:To enable only patient data to be recorded without attaching/detaching a camera as well as to facilitate the retrieval of endoscope images by displaying only patient data on monitors which display both of the endoscope images and patient data. CONSTITUTION:In case of data display mode, the CPU 26 opens a switching circuit 21 so as to transmit no image signal to a superimpose circuit 22, but in case of inspection image display signal mode, image signals are transmitted to the circuit 22. In either case, the CPU 26 transmits the signals designating the character of a character ROM 29 which houses characters correponding to patient data. The character ROM 29 reads out the designated character so as to transmit it to a video RAM 31 for writing it during the vertical flyback time. The video RAM 31 reads out the inputted character so as to output it to the superimpose circuit 22. The superimpose circuit 22, therefore, outputs image signals superimposed by characters when the image signals are inputted, and also outputs only characters onto monitors 4 and 23 when no image signal is inputted.

It costs ¥1.

[Prior art and problems to be solved by the invention] In recent years, a charge-coupled device (COD) has been installed at the distal end of the insertion tube as an imaging means.
Various types of electronic endoscopes equipped with image carriers are used, such as electronic endoscopes equipped with solid-state image carriers such as , and endoscopes with television cameras attached to the eyepieces such as fibrescopes. ing.

Further, the endoscopic image obtained by the endoscope is recorded by an endoscopic image recording device. When recording endoscopic images, use the data imprinting device to record 1 part of the film.
Scratch data and patient name all over the piece.

Data such as age, gender, date, etc. are imprinted, and then @shading of the family celebration ms is performed from the second frame. However, when using a conventional endoscope data imprinting device to imprint scribe data over almost the entire front surface of the first frame of the film, the camera is attached to the data imprinting device, and the data can be read from the data display of the data imprinting device. The data is directly captured, and then a camera is connected to an endoscopic image recording device to capture the endoscopic image. For this reason, it was troublesome to imprint the marking data.

In particular, there are 20 sheets of film, but often more than 20 sheets are used for one patient, which requires changing the film. It was repeatedly attached to the data imprinting device.

Also, if you do not imprint the scribe data and observe the photographed film with a projector, the film will be 16 m long.
Since the size is 35+am+ or 35+am+, it is difficult to visually confirm which patient it belongs to.

Furthermore, Japanese Patent Application Laid-Open No. 12639/1983 discloses a technique in which a data display body is disposed within a light gland device and data on the data display body illuminated by light leakage from a light source is photographed using a camera attached to the light source device. However, even with this technology, cameras had to be attached to each device to copy the data and take endoscopic images.

The present invention has been made in view of the above circumstances, and it is possible to record only patient data without attaching or detaching a camera, thereby making it possible to easily search recorded endoscopic images. The purpose is to provide endoscopic images and recording devices.

[Means and effects for solving the problem] The endoscopic image recording device of the present invention displays patient data on a monitor that displays an endoscopic image obtained from an endoscope and patient data input from a data input device. It is possible to display only the

In the present invention, patient data input from a data input device is displayed on a monitor screen. When only patient data is recorded, the characters of this patient data are larger than the characters of patient data displayed together with the endoscopic image.
