Description

  The present invention relates to an ophthalmic treatment safety system for monitoring a patient who has undergone eye surgery such as retinal detachment.

  Retinal detachment is a disease having a relatively high morbidity of about 1 in 10,000 people a year. If left unattended, it can lead to blindness, so surgery and postoperative management are important. In order to bring the detached retina into close contact with the eyeball wall, it is said that a treatment method in which gas is put into the eye by surgery and the prone posture is maintained for a long period of 2 weeks to 1 month after the operation is said to be most effective for retinal reposition. However, there is a problem that the patient's physical and mental burden is so large that the patient's cooperation is difficult to obtain and the treatment implementation rate does not increase.

  Japanese Patent No. 3069087 “Post-eye surgery patient leaning table” is registered in the invention to reduce the physical burden.

As mentioned above, because it is difficult to obtain cooperation from patients, in order for patients to maintain the posture necessary for treatment, medical staff such as nurses have to look around frequently and be careful. Effort. Especially during sleep, it is difficult to control the patient's consciousness and must be monitored closely.

Part.
In the prone posture holding bed according to the fifth aspect of the present invention, an opening corresponding to the patient's mouth and nose is formed in a part of the top plate, and a forehead support and a chin support are provided at the edge of the opening. The other part of the top plate is formed with a depression corresponding to the patient's stomach.

  According to the present invention, it is possible to improve the treatment implementation rate of patients who have undergone eye surgery such as retinal detachment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, the flow before and after the retinal detachment operation will be briefly described. First, before the retinal detachment operation, the patient needs to agree to the cooperation of the prone treatment with the informed consent of the attending physician. At this time, the attending physician should fully explain to patients and their families the importance of treatment to maintain the prone state with the face facing down, and agree to monitor the safety of the treatment after surgery. Get from the patient. At this time, make the patient understand that it is not desirable for treatment to change the orientation of the head (face) from the prone state, and warn when the orientation is changed excessively (for example, electronic sounds or recorded voices, etc.) ) Will occur and explain the response at that time, and to record the number of times the face direction has been changed excessively and the accumulated time that has been changed in order to use it as a guideline for treatment cooperation status. Explain enough. After the operation, the patient wears, for example, an ear hook type or ear hole type head angle sensor resembling the form of a hearing aid under the direction of the attending physician. At this time, the attending physician individually determines the allowable angle range for each patient according to the condition of the patient's retina, the state of gas in the eye, the degree of freedom of the body, the result of the operation, and the like. Further, the patient wears an angle sensor (torso angle sensor) different from the head angle sensor on the chest part, for example, the chest. The position of the patient can be determined by the torso angle sensor. That is, it is possible to distinguish between the posture in which the patient stands (standing) and the posture lying on the bed on his / her face down.

  An opening corresponding to the patient's mouth and nose is formed in the upper part of the top plate to prevent the patient from changing the direction of the face from below even when the patient is unconscious such as during sleep, and the edge of the opening Is provided with a forehead support unit and a chin support unit, and a bed is prepared in which a hollow portion for receiving the swelling of the patient's chest and stomach is formed in the substantially central portion of the top plate.

  The prone treatment is started and the patient keeps the posture as instructed by the doctor, but if for some reason the face is turned too far down, back and forth, left or right, an electronic sound or sound will be recorded. A warning sound such as a voice is sent to the nurse and the medical staff in charge of monitoring at a remote location, such as a nurse station, to alert the nurse that the patient's face has changed excessively from below. At this time, the warning information for the patient is only voice, but the voice and the patient information for identifying the patient are transmitted to the person in charge of monitoring. The means used for the alarm may be a dedicated display screen provided in a nurse station, or software on a computer connected by a network, or a PHS that is carried individually by a medical worker such as a nurse. The communication means may be used. The supervisor will look at the warning situation and, if deemed necessary, go to the patient's location to alert the offending patient. Alternatively, remote communication means such as a video phone may be used.

  The head angle data is periodically measured at a preset period of, for example, 5 seconds. All measured head angle data is recorded together with the measurement time data. Alternatively, only head angle data when the face orientation changes excessively from downward is recorded, and head angle data when the face orientation is maintained substantially downward is not recorded. Based on the head angle data accumulated during the monitoring period, a report is generated that includes the number of times the patient head angle has changed excessively from below and the accumulated time. Based on this, the doctor can confirm the treatment status of the patient and can provide patient guidance. In the unlikely event that treatment of a patient who is not cooperative with treatment fails and a medical lawsuit occurs, it is possible to prove the responsibility of the patient based on this data. The report can be created in various formats desired by the user, such as the number of times and the accumulated time, as well as the details of the angle violation, the number of violations, and a graph of the violation time for any period.

  The patient cannot turn up at the time of eye drop administration, doctor examination, or additional treatment by the doctor, but it is necessary to turn the monitoring temporarily by the doctor or nurse in charge because it is necessary to face straight ahead. is there. For this purpose, a doctor or nurse can use an authentication means such as a password to temporarily cancel the alarm and records whether or not the alarm has been released together with the head angle data. Data cannot be altered if it is used as medical record information or has a purpose for use in medical lawsuits, so data can be edited for master information that cannot be changed and for research purposes. Two types of information are recorded.

  FIG. 1 shows the configuration of the ophthalmic treatment safety system of the present embodiment. This ophthalmic treatment safety system includes a head angle sensor 11 and a torso angle sensor 12. There are no particular restrictions on the sensor type employed for these angle sensors 11 and 12, electromagnetic induction type, electrical resistance change type, strain gauge type, light / infrared type, Hall effect type (magnetoresistance type), acoustic wave type, mechanical type Any type of angle sensor that is currently in common use, such as a static displacement type, a gyroscope type, and a capacitance type, is employed.

  As shown in FIGS. 2A to 2D, the head angle sensor 11 is a single angle sensor capable of individually measuring an angle with respect to at least two orthogonal axes, or arranged in an orientation in which the measurement axes are orthogonal. It consists of two uniaxial sensors. The angle around one axis of the two measurement axes roughly corresponds to the head front-rear angle as the angle of the front of the face with respect to the front-rear movement of the neck relative to the vertical direction, and the other angle is the left-right swing of the neck relative to the vertical direction. The head angle sensor 11 is attached to the patient in a direction substantially corresponding to the left and right head angles as the face front angle relating to movement. The head angle sensor 11 alone is used together with an alarm device (patient) 21 or an angle determination unit 13, a body position determination unit 14, a control unit 15, a limit angle setting unit 16, a warning transmission unit 17, a time information stamper 18, and data. The housing 19 and the alarm device (patient) 21 are housed in an ear-hook type or ear-hole type housing similar to the form of a hearing aid. The head angle sensor 11 is separate from the main body unit including the angle determination unit 13, the body position determination unit 14, the control unit 15, the limit angle setting unit 16, the warning transmission unit 17, the time information stamper 18, the data storage unit 19, and the like. For example, it is preferable that the main unit is connected with a wireless system that employs, for example, an FM modulation method. Further, when the alarm device (patient) 21 is configured separately from the main body portion together with the head angle sensor 11, it is preferable that the main body portion is connected by a wireless system in the same manner as described above.

  The torso angle sensor 12 is an angle sensor capable of measuring an angle with respect to at least one axis, and the measurement axis is substantially orthogonal to the patient body axis so that the patient's body position (standing position (standing up), lying on the prone position) can be distinguished. For example, it is mounted on the patient's chest. The torso angle sensor 12 alone, together with the alarm device (patient) 21, or the angle determination unit 13, the body position determination unit 14, the control unit 15, the limit angle setting unit 16, the warning transmission unit 17, the time information stamper 18, The data storage unit 19 and the alarm device (patient) 21 are housed in a housing. In addition, when the trunk | body angle sensor 12 is comprised separately from the main-body part, it is preferable to connect with a main-body part by a wireless system similarly to the above.

  The angle determination unit 13 exceeds the limit angle set by the operator via the limit angle setting unit 16 at least one of the head front-rear angle and the head left-right angle measured by the head angle sensor 11. Whether or not the patient's face is tilted back and forth or left and right beyond the limit angle from below. The control unit 15 is determined by the angle determination unit 13 that at least one of the head front-rear angle and the head left-right angle measured by the head angle sensor 11 has exceeded the limit angle, and the monitor is released. When not, the alarm transmission unit 17 is controlled to generate an electronic sound, a recorded voice, or the like as an alarm from the alarm device 21 attached to the patient or installed in the vicinity thereof.

  Even when at least one of the head front-rear angle and the head left-right angle measured by the head angle sensor 11 exceeds the limit angle, monitoring is performed by the operator via the monitoring release operation unit 33. When the release state is set, the control unit 15 stops the control on the alarm transmission unit 17 for generating an alarm from the alarm device 21.

  Further, the control unit 15 determines that at least one of the head front-rear angle and the head left-right angle measured by the head angle sensor 11 has exceeded the limit angle and is not in the monitoring release state, for example, An alarm is generated from the alarm device 22 installed in a nurse as a medical staff in charge of monitoring at a remote place such as a nurse station or installed in the nurse station packed by the nurse, and the direction is excessively increased. The alarm transmitter 17 is controlled to display on the alarm device 22 information identifying the changed patient and its position. The alarm device 22 displays an electronic buzzer and a speaker that generate an electronic sound, a recorded voice, and the like, and information for identifying the head angle sensor 11, that is, information for identifying a patient wearing the head angle sensor 11, and its posture. Display or a plurality of lamps.

  Based on the angle measured by the torso angle sensor 12, the body position determination unit 14 determines whether the patient is in a standing posture or in a lying posture. This body position data is recorded in the data storage unit 19 together with the time data from the time information stamper 18, the head longitudinal angle data, and the head lateral angle data. Based on the head longitudinal angle data, the head lateral angle data, the body position data, and the time data recorded in the data storage unit 19 during the monitoring period, the report creation unit 20 performs the patient head longitudinal direction as illustrated in FIG. A report is created that includes the number of times that at least one of the corner and the head left / right corner exceeds the limit angle, its accumulated time, posture, presence of alarm, and status of monitoring cancellation. This report data is transmitted to an external computer via an arbitrary interface, and is displayed and printed as necessary.

  In order to make it easier to maintain a prone posture, especially when unconscious, such as during sleep, a “bed for holding a prone posture” shown in FIG. 3 is prepared. A substantially elliptical opening 32 corresponding to the patient's mouth and nose is formed on the top plate 30. A forehead support 31 made of a low resilience material or the like is attached to the upper edge of the opening 32 in order to relieve long-time pressure stimulation. Similarly, a chin support 33 is attached to the lower edge of the opening 32. Further, a recess 34 for receiving the swelling of the patient's chest and stomach is formed in the substantially central portion of the top plate 30.

  FIG. 4 shows a head angle monitoring operation procedure according to this embodiment. First, a limit angle and a monitoring period are set by an operator via a limit angle setting unit 16 having an input device such as a keyboard and a mouse (S10), and a monitoring operation is performed together with a monitoring trigger input via the limit angle setting unit 16. Is started (S11). Until the monitoring period elapses after the start of monitoring (S19), the angle sensors 11 and 12 repeat the head longitudinal angle, the head lateral angle, and the angle for posture determination in a predetermined period of, for example, 5 seconds. It is measured (S12). The measured head front / rear angle data, head left / right angle data, and body position data identify time data representing the measurement time from the time information stamper 18 and monitoring / monitoring cancellation (alarm generation permission / alarm generation prohibition). The data is recorded in the data storage unit 19 together with the data to be processed (S13).

  When one or both of the measured head front-rear angle and head left-right angle exceed the limit angle (S15, S16) and are not in the monitoring release state (S14), the control unit 15 sends the alarm transmission unit 17 And alarms are generated from the alarm devices 21 and 22 to the patient and the medical staff (S17, S18). A warning sound is generated from the alarm device 21 of the patient, and a warning sound is generated from the alarm device 22 of the medical staff, and information for identifying the patient whose orientation has been changed excessively and its posture are displayed.

  When the monitoring release state is set, even if one or both of the measured head front-back angle and head left-right angle exceed the limit angle, no alarm is issued to the patient and medical staff. The monitoring cancellation is typically set at the time of eye drop medication, at the time of examination by a doctor, or at the time of additional treatment by a doctor.

  Thus, according to this embodiment, when the head (face) is excessively tilted from the prone posture, an alarm is generated to the patient and the medical staff. With the alarm as a trigger, the patient can recognize that the head direction is inappropriate and correct it. In addition, the medical staff can effectively pay attention to the orientation of the head toward the patient in a timely manner, and can reduce human labor. This can be expected to improve the treatment implementation rate. In addition, record each data of head front / rear angle, head left / right angle, body position, measurement time and monitoring / monitoring cancellation when the head is tilted excessively or every time measurement is performed. This can be done effectively with reference to the explanation.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
