The subject may be a human, but may be an animal or a plant in addition to the human. In addition, the medical device 200 may be various types of devices such as ringer regulators, respirators, nebulizers, humidifiers, life support devices, and the like.

The sensor 110 is attached to the object or embedded in the body of the object to sense the biosignal. For example, the sensor 110 may be implemented as at least one sensor that senses various states such as ECG, respiration, oxygen saturation, blood pressure, carbon dioxide, body temperature, or various states such as cough sound volume and cough frequency.

The signal processor 120 receives the biosignal from the sensor 110. The signal processor 120 analyzes the received biosignal and provides the analysis result to the controller 140.

The storage unit 130 stores characteristic information about the object. The characteristic information includes sensing information about various items such as ECG, respiration, oxygen saturation, blood pressure, carbon dioxide, and body temperature, in addition to personal information such as the name, age, height, and weight of the subject, and allowable range information recorded by a doctor for each subject. And the like. The sensing information may include a result sensed in the normal state and a result sensed in the previous state. The characteristic information may be input by a doctor or a nurse or other staff who treats a patient, and may be stored in the storage unit 130.

The signal processor 120 may analyze the biosignal using the characteristic information stored in the storage 130. Specifically, the signal processor 120 may calculate the magnitude, frequency, average value, and the like of the biosignal. The difference value may be calculated by comparing the calculated value with at least one of allowable range information in the characteristic information, a steady state sensing result, and a previous state sensing result.

The controller 140 determines the prescription content for the object using the analysis result and the characteristic information of the signal processor 120. The controller 140 controls the medical device 200 corresponding to the object according to the prescription contents.

In detail, the controller 140 may control the medical device 200 to perform various types of operations such as starting a medical procedure, stopping a medical procedure, starting a dosage, stopping a dosage, adjusting a dosage rate, changing a drug type, and the like.

Here, the medical procedure means nebulizing, humidification, oxygen supply, and the like. That is, when it is determined that the ECG, respiration, oxygen saturation, carbon dioxide, the number of coughs, the cough sound, etc. have deviated from the normal state, the controller 140 turns on a nebulizer, a humidifier, an oxygen supplier, and starts a medical procedure. On the other hand, if it is determined that the state of the subject has returned to the normal state, the medical procedure is stopped by turning off the nebulizer, the humidifier, and the oxygen supply.

In addition, the controller 140 may turn on or turn off the controller mounted on the ringer bottle or the hose connected to the object to perform the start of dosing or stop the dosing, and may control the dosing rate by adjusting the pressure. In addition, the caps of the plurality of vials connected to the Ringer bottle and the plurality of regulators mounted on the connecting hoses may be selectively turned on or off to change the type of drug supplied to the subject.

Regulators can be implemented in a variety of forms. For example, the regulator may be implemented in a form including a forceps for holding the hose and a hinge for moving the forceps. The hinge unit may include an actuator driven according to a control signal applied from the controller 140. The actuator may expand in volume in response to a control signal to relax or contract the forceps. As a result, the controller 140 may control the regulator to adjust whether the ringer liquid is added, the feeding speed, and the like.

The controller 140 may utilize the biosignal sensed by the sensor 110 in various ways.

According to the control of the various medical devices (200-1 ~ 200-m).

The type and control content of the medical device may be variously described as described above, and thus redundant description is omitted.

The communication interface unit 150 is a component for performing communication. In detail, the communication interface unit 150 may perform communication by using manager information stored in the storage unit 130. The administrator information may be a telephone number, a mail address, an IP address, or the like. The manager information may be stored by matching the characteristic information of the object with a doctor or a nurse or other staff member who has treated the object.

The controller 140 controls the communication interface 150 to transmit a notification signal to the manager information stored in the storage 130 when the biological signal sensed with respect to the object is out of the normal range. The normal range means a range of statistically measured normal values for each item. The notification signal may be a mail, a Short Message Service (SMS) message, an alarm, or the like.

According to an embodiment, the controller 140 may control the communication interface unit 150 to transmit a notification signal when the time when the time out of the normal range is maintained for a predetermined threshold time or more.

The input unit 170 is configured to receive the above-described characteristic information, various user commands, and the like.

The controller 140 may store the change in the biosignal sensed by the object in the storage 130.

When the characteristic information about the object is input through the input unit 170, the controller 140 may match the object and the characteristic information and store the matching information in the storage unit 130.

The display 160 may display various messages as a result of sensing by the sensors 1 to n (110-1 to 110-n).

When a display command is input through the input unit 170, the controller 140 may control the display unit 160 to display a change history of a biosignal stored for the object and a prescription history for the object.

The input unit 170 may be implemented as a button provided in the main body of the medical device control system, or may be implemented as a touch screen provided in the display unit 160.

3 is a view for explaining a method of managing a patient using a medical device control system according to an embodiment of the present invention.

According to FIG. 3, at least one sensor is attached to the object, that is, the body of the patient 10. Each sensor senses the state of the patient 10 and transmits the sensing result, that is, the biosignal to the medical device control system 100 according to a wireless or wired communication protocol. Communication protocols can be implemented in a variety of known standards.

Although only one patient 10 is illustrated in FIG. 3, a sensor is attached to each patient in each room to manage the medical device control system 100.

The medical device control system 100 continuously monitors and analyzes the condition of the patient 10, determines the prescription content according to the analysis content, and various medical devices 200-200 for the patient 10 according to the determined prescription content. 1 to 200-4). In FIG. 3, the first medical device 200-1 refers to an adjuster for adjusting a ringer. The remaining second to fourth medical devices 200-2, 200-3, and 200-4 may be various medical devices such as a respirator, a nebulizer, a humidifier, a life support device, and the like.

The prescription contents of the medical device control system 100 may be determined differently according to the characteristic information previously input by the doctor 20. In other words, when the age is small or when the weight and height are small, the dosage rate and the dosage amount may be set small, and in the opposite case, the relatively large size may be set, and the drug type may be set differently according to the characteristic information. Can be. In addition, depending on the specific environment of the patient 10, for example, allergic reactions, drug side effects, hospitalization period, etc., the dosage rate, dosage amount, drug type, etc. may be set differently.

Such prescription information may be input by the doctor 20 in advance, or the medical device control system 100 may learn itself through statistical training. For example, if the biosignal change of a male patient aged 8 years to 13 years is within the first range, the doctor may store the corresponding information if there is a diagnosis. If the same prescription is repeatedly stored over a preset threshold or threshold ratio, after the change of the biosignal under the same condition is measured, the medical device control system 100 may automatically determine the prescription even if the doctor does not make a separate diagnosis. have. The medical device control system 100 may be trained in the use process after the product is released, and is equipped with a database that organizes prescriptions based on clinical results before the product is released, to automatically determine prescriptions according to the database. It can also be implemented.

Meanwhile, if it is determined that the analysis result of the biosignal is abnormal, the medical device control system 100 may automatically transmit a notification signal to the doctor 20, the nurse, the staff, or other caregivers.
