Description

The present invention relates to a nurse call system used in hospitals and welfare care facilities.

As is well known, a nurse call system is mainly installed in a hospital or welfare care facility for a patient to talk to a nurse (caregiver in a welfare care facility). In this nurse call system, a nurse call cordless handset used by a patient for calling is provided in each bed, and a nurse call master phone is installed in the nurse station so that a call can be made between them. (See Patent Document 1)

In recent years, nurse call systems have been used not only for calls between nurses and patients, but also for emergency calls where patients can be contacted even when nurse calls cannot be made. For example, when a nurse call system and a ventilator are connected and the ventilator stops or the patient becomes suffocated, the nurse is notified of the abnormality. The present invention, in the case of an emergency using an emergency medical device centered on an automated external defibrillator (AED) installed in a hospital, a welfare care facility, an elderly housing complex, etc. The challenge is to call automatically and request support from medical professionals and related parties.

In order to save a patient with cardiopulmonary arrest or fatal arrhythmia, resuscitation using an automatic external defibrillator is necessary as soon as possible. It is said that about 90% of patients can return to society if defibrillation is performed within about 1 minute after the attack, and about 70% or more can return to society within about 3 minutes. In other words, the possibility of saving is said to decrease by 10% every minute, and it is said that the possibility of survival becomes very small after 10 minutes. In such a situation, it is important to have many rescuers and cooperators. As an example of reporting to a rescuer, when an implanted medical device embedded in the body of a patient with heart disease detects an abnormal value of the heart, a rescue signal is transmitted outside the body and rescue request information including position information is sent to a remote location. A proposal to report is made. (See Patent Document 2)

Patients with cardiopulmonary arrest or fatal arrhythmia attacks are often unable to nurse call. For this reason, at-risk patients are monitored by a biological information monitoring device such as an electrocardiogram, and the information reaches the nurse station. However, not all patients are monitored by the biological information monitoring device. When using emergency medical devices such as automatic external defibrillators (AEDs), there are many cases where there is no time to call for support, but there is a lot of cooperation with medical staff such as medical and nursing staff. I am saved. Also, if an emergency discoverer contacts or calls the associated health care professional, that alone will spend valuable time. This invention makes it a subject to notify automatically in order to ask | require cooperation of another medical worker when utilizing an emergency medical device.

The emergency medical device is stored in a predetermined place, a predetermined storage box, or mounted in a predetermined emergency cart so that anyone can use it immediately. A means for detecting movement or removal when the emergency medical instrument is moved from a predetermined place is provided, and means for notifying the detected information to the nurse call parent device and the portable terminal carried by the medical staff.

When an emergency medical device is moved from a predetermined place, it is equipped with means for detecting movement or removal, and the detected information is carried by a preset medical worker instead of the nurse call master unit and all medical workers. Means for informing the mobile terminal.

Means for attaching a radio transmitter or an IC tag to an emergency medical instrument or a transport vehicle (emergency cart) carrying the emergency medical instrument, and a radio transmitter or an IC tag reader provided at a predetermined place and the entrance of each hospital room Means for reading the identification number of the emergency medical device transmitted from the IC tag, means for transmitting the information of the identification number read by the wireless receiver or the IC tag reader to the corridor lamp, the nurse call parent device and the portable terminal from the corridor lamp A means for transmitting an identification number to the medical staff, and a means for notifying the medical staff of the type of the emergency medical instrument and the travel route and arrival location of the emergency medical instrument or the transport vehicle carrying the emergency medical instrument from the identification number of the emergency medical instrument .

When an emergency medical device is used, it is automatically notified to related persons such as medical workers, so the notification is fast and a collaborator can be obtained immediately.

Finders of emergencies can save time in contacting other health care professionals. Therefore, time is not wasted when competing for a moment.

There is a sense of security that the collaborators come to report to the medical staff and other related parties automatically.

It is possible to prevent the emergency medical device from being moved without permission. No one should know where to store emergency medical equipment and look for it in an emergency. Even if there is no intention to intentionally move the emergency medical device, it may be moved by cleaning or construction of equipment, and may be left moved. When the emergency medical device is moved, the person concerned is notified. Therefore, if it is determined whether the movement is not an emergency use, it can be prevented from remaining moved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration diagram of an entire nurse call system capable of reporting the removal and movement of an emergency medical device. Nurse call cordless handsets (7 and 8) were installed at the bedside, and when the patient pressed the call button, the call signal was placed near the entrance of the sickroom, the wall mounted cordless handset (6) attached to the wall of the sickroom It is transmitted to the nurse call master unit (2) via the corridor lamp (5), nurse call communication line (19), nurse call control unit (3), and the call display is displayed along with the ringing sound in the nurse call master unit (2). Is output. If a nurse or the like responds to the call, a call path is formed between the nurse call parent device (2) and the nurse call child devices (7 and 8), and a call can be made.

Calls from the nurse call slaves (7 and 8) are sent from the nurse call controller (3) via the cordless main unit (4) having the function of the private branch exchange and the radio base station unit (18) to the doctor or nurse. If it is transmitted to the portable terminal (17) carried by a medical worker such as a nurse and responds at the portable terminal (17) prior to the response at the nurse call parent unit (2), the nurse call slave unit (7 and 8) A call can be made between the portable terminals (17).

The processing of patient information including nurse call calls is performed by the processing device (1), and the processed, collected and aggregated data is stored in the server (9) via the local area network for nurse calls (20). Data is managed centrally. Although only one processing device (1) is shown in FIG. 1, processing devices in other wards are also connected to a LAN (local area network) to exchange data with the server (9). Is called.

The emergency medical instrument (15) is stored in a predetermined storage box (10) or an emergency medical instrument transport vehicle (emergency cart) (14) placed at a predetermined position. A sensor for detecting that the emergency medical instrument (15) has been removed or moved is attached to the storage box (10) or the emergency cart (14). The sensors include weight sensors and pressure sensors that detect removal and movement by the weight of the emergency medical device, optical sensors that detect movement of the position using light reflection and shielding, and mounting wires and attachments for emergency medical devices. Any sensor such as a sensor that detects that the chain has been removed, a radio wave sensor that detects movement of a position using radio waves, or a door switch that detects that the door of the storage box has been opened may be used.

The removal detection device (11) and the removal / movement detection device (12) include at least one of the above-described various sensors, and the emergency medical device (15) is removed or moved when the nurse call child device is moved. (7 and 8) or the detected signal is sent to the wall mounted slave (6). The removal / movement detecting device (12) detects not only the removal of the emergency medical instrument (15) but also the movement. For example, an emergency cart placed on a pressure-sensitive mat moves to know that it has moved because it no longer senses the pressure on the emergency cart. If there are a plurality of types of emergency medical devices (15), the removal detection device (11) and the removal / movement detection device (12) add an identification number to identify the type, and the wall mounted slave (6), etc. Send to.

The corridor lamp (5) that has received the signal that detected the removal or movement notifies the other medical personnel by turning on or blinking the warning lamp, and also via the nurse call controller (3). 2) and the mobile terminal (17). The nurse call base unit (2) and the portable terminal (17) display the place where the emergency medical device (15) was used and the type of emergency medical device (which can be determined from the identification number), and make a sound and engage in medical care. Inform the person.

If the removal or movement of the emergency medical device is not intended, the restoration button for resetting the signal is provided on the corridor lamp (5), the removal detection device (11) or the removal / movement detection device (12). Press to cancel the alarm.

Although it is possible to notify all portable terminals (17) of the removal or movement of the emergency medical device, it is also possible to notify only a specific medical worker. FIG. 2 shows an example of an emergency medical device and a contact list. It can be set in the operation unit of the nurse call master (2) or the display / operation unit of the processing device (1), and the list is stored in the storage unit of the nurse call controller (3). It is possible to change the contact information depending on the type of emergency medical equipment and the place of use. As the contact information, a mobile number is registered, and a nurse name and a doctor name are registered. When registering a nurse name or doctor name, refer to a list of medical workers and mobile numbers registered separately. When the nurse call control device (3) receives the signal that detects the removal or movement of the emergency medical device, the nurse call control device (3) refers to the contact list stored in the storage unit and sends the contact number to the cordless main device (4). Specify and call.

FIG. 3 is a diagram illustrating a moving path of the emergency medical device. Install an IC tag reader (13) or wireless receiver (not shown) at a predetermined location and close to the IC tag (16) or wireless transmitter (not shown) to which an emergency medical device is attached. When traveling, it can receive a radio signal including an identification number to know the travel path of the emergency medical device.

The identification number of the emergency medical device read by the IC tag reader (13) is sent to the corridor lamp (5), and further via the nurse call controller (3), the nurse call master (2) and the portable terminal ( 17).

In FIG. 3, when the movement from No1 to No2, No3, No4 passes nearby, the IC tag (16) to which the emergency medical device is attached is read by the IC tag reader (13) at each position. It turns out. An IC tag reader (13) is also installed at the entrance of each hospital room (corresponding to No. 4 in FIG. 3), so that the room entry location can be determined. In the nurse call parent device (2) and the portable terminal (17), the route display and the reached location are shown, and the supporter can rush to that location.

In the case of a wireless transmitter, since it is necessary to be driven by a battery, it is desirable that the power is not turned on so that the battery is not consumed during storage. . In the case of an IC tag, since an induced electromotive force of the IC tag reader (13) is used, a battery is not necessary for the IC tag.

The present invention can be used not only in hospitals and welfare care facilities but also in elderly apartment houses. In this case, the report destination is the management center.
