DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical information system in a hospital or the like, and more particularly, to record and refer to a patient's condition by video information to supplement document record information, thereby facilitating and ascertaining a high-quality patient condition. Regarding the enabled system.

[0002]

2. Description of the Related Art Information recorded in medical records at hospitals and the like covers all medical activities such as consultation, examination, and treatment. Since it can be said that all the information of a patient is collected in the information of the medical chart, the doctor can grasp the condition of the patient by referring to the medical chart. For example, at the time of medical treatment of a certain patient, the patient first refers to the medical chart and takes in the information of the patient into himself. That is, the physician elevates himself to a condition specific to the patient. Therefore, it is desirable that the medical record includes not only mere medical records and data but also information that reflects the patient state at the time of describing the medical record more abundantly. For example, it is extremely effective if media that plays an important role in normal human communication, such as the patient's facial expression, movement, response, tone of voice, and atmosphere, can be reflected. However, in the conventional method, information other than the information described in the medical record is not always available. Therefore, it is considered that there is a case where information is insufficient only with the medical record. In the case of self-written handwritten characters, symbols, pictures, figures, and the like, it is common that information other than the written contents is comprehensively stored with the help of human memory / recognition structure. That is, it is conceivable that the handwritten chart is supplemented with important information outside of the chart through the human pattern recognition ability, thereby facilitating the doctor's understanding of the patient's condition. However, this is an effect on the writer himself and is useless for others. Further, since most of the electronic medical record information is encoded, the above effects cannot be expected.

[0003] Furthermore, in the case of emergency medical care, it is not always easy to record the condition of a patient and the contents of medical treatment on the spot, and recording on a medical record is often performed afterwards. Therefore, there is a problem that a detailed description of a patient's condition is not easy.

[0004]

As described above, in the conventional method, there is a problem that information may be insufficient in grasping the condition of the patient and the details of the medical treatment.

Therefore, an object of the present invention is to provide a medium which is a major medium in ordinary human communication,
An object of the present invention is to provide a system that can use information that is difficult to document or express in charts as a chart entry.

[0006]

According to the present invention, there is provided a system and environment in which information relating to medical treatment for each patient is recorded as video information and can be used. That is, by arranging cameras so as to obtain information close to the situation in which a doctor examines a patient, or arranging a plurality of cameras from various directions, the movement, response, facial expression, etc. of a patient can be recorded. Control the camera. Inspection,
The camera arrangement of the entire hospital may be such that information such as treatment can be recorded. For example, a camera is arranged at a position close to the line of sight of a doctor, such as a consultation desk, and the facial expressions, actions, responses, and the like of the patient are recorded in a form similar to the situation seen by the doctor. At this time, the angle and position of the camera can be controlled in conjunction with the doctor's line of sight and body movement. Alternatively, an image from an angle different from the doctor's line of sight may be available as new useful information. A particularly important condition here is that the recorded video information be made available in conjunction with a reference to the patient's chart. In other words, in conjunction with the chart reference operation,
For example, the system displays related video information of the patient, for example, at the time of previous medical treatment.

[0007] For emergency medical care, a camera that moves with the movement of the patient is provided so that a series of video information such as patient reception, examination, consultation, and treatment can be recorded. Related video information is recorded by controlling a plurality of installed cameras in an interlocked manner.

At the time of recording the video information, search key information is attached to each recording unit in order to enable synchronous reference to other information such as a chart. That is, the information includes a patient ID (personal identification code), a doctor ID, a date, a time, a department, and other necessary information. Recording is not limited to a particular format,
The system should be suitable for common use in hospitals. For example, a standard television system, a standard video tape (VTR) or a video disk recording system can be used, and a recording medium such as a video tape or a video disk can be used. The recording device has means for adding the search information, and the reproduction display device has means for searching and displaying information for each recording unit in accordance with the search information.

The activation of the recording device is controlled in conjunction with the movement of the patient. For example, when a patient is examined, patient I
Since the patient's chart is opened by D or the like, the recording device is started using this information, and the above-mentioned search information is generated and recorded in a predetermined format, and recording of video information is started. At the same time, based on the search information, a search for related video information at the time of a previous consultation or the like is performed, and the content is displayed. The recorded information is stored and managed together with the management information. That is, registration of new information, addition of information, deletion of used or unnecessary information, management of a recording medium, and the like are performed.

[0010]

The present invention is characterized by utilizing the advanced human recognition ability by utilizing video information. That is,
By utilizing sight and hearing, a large amount of information can be captured naturally without paying special attention, and the contents can be instantaneously understood. Therefore, the effectiveness of the method of the present invention triggered by video information in grasping patient information is easily understood.

The recording of the video information is controlled by appropriately arranging a camera in a consultation desk or a medical environment such as an examination or a treatment, and correlating the camera with a medical condition of a patient. The association with the medical condition of the patient utilizes the operation information of the patient's chart, that is, the search information generating means of the video information is driven by the patient identification information for the chart operation, and the recording system and the reproduction system are controlled. That can be done. The control of the photographing means such as the position and angle of the camera and the zoom control can be changed according to medical conditions, in addition to preset conditions. For example, the operation and position of the doctor,
Alternatively, a photographing condition is controlled by providing a sensor such as a line of sight.
The number of cameras may be plural. For example, it is arranged at an appropriate position in a medical environment for medical examinations, examinations, treatments, and the like, and the images are switched and controlled and recorded for each target patient.

D) and a doctor identification code (doctor ID) input means. Here, the part composed of 3, 30, 7, 6, etc. is the conventional system, and the other parts are parts unique to the present invention.

In the medical treatment in the conventional system, the doctor opens the patient's medical record based on the patient and the doctor ID, refers to the examination data, refers to the findings and other records, grasps the condition of the patient, and then performs the medical treatment on the day. . That is, since a physician deals with many patients, it is necessary to rapidly build up his or her informational state to the patient's state. As this means, document information such as a chart is mainly used in the conventional system. On the other hand, in normal communication, high-speed and detailed recognition ability is exhibited by utilizing media other than document information such as voice and video.

Accordingly, the present invention provides a system for utilizing video information at the point of care. The video information is taken in by the camera 10. The output from the camera is recorded by a recording system 1 including a video recording device. Here, search information of recording information is recorded prior to the video information recording. The search information includes a patient ID, a doctor ID, a date, a time, a treating department such as a medical department or a laboratory, and information reflecting other search conditions. That is, it is possible to search for recorded video information on the basis of each of these and combinations thereof. The search information can be generated by information from the electronic medical record system 3 in addition to being input each time. That is, the search information is basic information necessary for searching and operating a medical chart, and is also used for search, control, management, and the like in the electronic medical chart system 3. Therefore, the recording with the relation between the patient's chart and the video is easily realized.

The search information generating means 5 inputs the converted data into a format compatible with the recording system 1 as a signal 51 to the control system 4 based on the data from the electronic medical chart system, and records the data through the signal 11 from the control system. The control system 4 is the camera 1

The storage management method of the medium is not particularly limited. In the present embodiment, the start of recording may be based on a signal from the electronic medical record system, or may be performed separately. The angle, position, focus, etc. of the camera can be set each time, even under preset conditions. For example, in the zoom adjustment, the normal mode and the enlargement mode are alternately switched, and the overall situation of the patient and the detailed expression can be recorded at the same time.

FIG. 2 shows another embodiment of the present invention using a plurality of cameras. The cameras 101, 102, and 103 are installed at different positions or places, respectively, and the output thereof is controlled by the switching signal 110 from the control system 4 to select one of them and guide it to the recording system 1. Subsequent functions,
The operation is the same as that of the embodiment of FIG. 1, but a plurality of recording media may be prepared here and the video of each camera may be recorded. Reference numerals 111, 112, and 113 in this embodiment are such a plurality of recording media.

FIG. 3 is a diagram showing another embodiment of a desk on which a doctor workstation or the like is placed as a medical environment to which the present invention is applied. Here, 90 is a desk, 70 is the doctor's workstation or a part thereof, 20 and 30 are medical chart and video information display devices in FIG. 1, respectively.
Reference numeral 10 denotes a camera, 91 denotes a support mechanism of the camera 10 attached to a desk 90, 92 denotes a doctor's chair, and 40 denotes a desk 9 of the chair 92.
This is a sensor for detecting a relative position, an angle, and the like with respect to 0. Since the camera 10 is installed at a position close to the doctor's head, the patient's attitude, facial expression, and the like can be recorded in a form close to the doctor's eyes. In addition, the angle of the camera is detected by the sensor 40 to detect the relative position of the chair with respect to the desk, and an actuator (not shown) provided in the camera support mechanism 91 is controlled so that an image close to the doctor's line of sight can be taken. Two display devices 20, 3
For example, the video and chart information at the time of the previous medical treatment are displayed in 0 in conjunction with the operation of the chart by the workstation 70, and compared to the conventional method of only the chart information such as detailed grasp of the patient state and instantaneous status grasp, It offers an advanced and easy medical care environment.

[0020]

As described above, according to the present invention, since the image and voice recognition capabilities possessed by humans can be used, the patient information can be grasped and the previous medical treatment can be performed without burdening the doctor such as special operations and processing. Can be grasped instantaneously, and an excellent effect which has not existed in the past can be obtained. In particular, it becomes easy for non-recorders to grasp detailed information as if they were present. This is particularly effective when a plurality of doctors are involved in one patient.

In the case of emergency medical care, the usefulness of video recording is evident since there are many situations where it is not possible to record the patient's condition and details of medical practice on the spot.
