CONSTITUTION: A system for measuring the pulse, blood pressure and oxygen saturation of a patient is added to a tilting table. The system comprises a BP module, a HR module, a tilting sensor, a serial multi-port, a micro controller, a desktop PC and an emergency switch all configured in a tilting table. The angle and time(speed) of operating the table is set according to the patient's state. Upon the generation of abnormality in the pulse and blood pressure, the table is restored to the original position.

Description

Horizontal and Angle Automatic Operation, Patient Medical Treatment Table {Auto Electric Tilting Table}

The present invention relates to a method of manufacturing a tilt table that can check the blood pressure, pulse, oxygen concentration of the patient while driving the medical tilt table, and control the angle and speed of the table according to the patient condition.

Tilttable, which is used to prevent bedsores, exercise, and blood circulation of patients who have difficulty in behavior such as stroke, inability to circulate, or to promote smooth blood circulation, is operated. Since the angle and speed of the table can not be adjusted, it cannot be driven at the proper driving angle and speed according to the patient's condition. In addition, there is no way to check the blood pressure or pulse on the table itself, so it is impossible to check the blood pressure or pulse state of the patient when driving the table.

The present invention solves the above problems and can adjust the driving angle and time of the table in accordance with the difference between the various types of patients and conditions, and continuously monitor the patient's state (pulse, blood pressure, blood oxygen concentration) during the table driving It is aimed at manufacturing the table and the way that the table can be recovered in the event of abnormal symptoms.

◎ Schematic description of the circuit diagram

Ⅰ) The table drive information (direction and speed) inputted to the first computer is transmitted to the 8-bit CPU AT89C2051 (micro controller) through the connector CONAT62 connected to the computer, and the speed of the table's D / C motor can be controlled by PWM method. The information is sent to the SN75174 and the control box of the table.

According to the transmitted information, the emergency switch device that controls the speed and direction in the control box of the table and automatically returns to the emergency when an emergency situation occurs is performed at 16VB.

Ⅱ) The angle and speed control of the table is the information inputted to the computer for the first time and continuously controlled from the operation of the table.

This control stores the information from the angler via the Tilting sensor, the SN75174, and the SN75175 circuitry, and saves the information to the LS7166 (angle angler count), which is sent to the computer via the CONAT62.

The angle information transmitted to the computer is compared with the driving information entered for the first time, and the new speed direction information is exported to the Micro Controller (AT89C2051) according to the driving information entered for the first time to adjust the table speed. This operation is repeated, and the table is activated with the time and angle entered first.

Ⅲ) Blood pressure & pulse and oxygen concentration of patient during table operation, blood pressure, pulse and oxygen concentration module are connected with com1, patient information is transmitted to computer through CONNTRBLK10 and transmitted information is monitored and stored on computer.

In addition, the upper and lower limits of the patient's blood pressure and pulse are inputted to the computer. When the patient's blood pressure and pulse rate are higher or lower than the upper and lower limits during operation, the computer sends STOP information to return to the far end.

As shown in FIG. 1, the configuration of the present invention includes a blood pressure module (BP Module), a pulse oxygen concentration module (HR Module), a tilting seonser, a serial medium, and a microcontroller in a tilting table. It consists of a Desktop PC and an Emergency Switch.

Table driving angle, time (speed) arbitrary setting method

If you input the angle and time to drive the table according to the patient's condition on the computer, the tilt time will be started by converting the driving time up to the set angle from the microcontroller. The drive angle is checked and the information is sent to the microcontroller through a serial multiport computer. The microcontroller then divides the tilt table into 250 stages and re-adjusts the speed of the tilt table.

How to check the patient's condition (pulse, blood pressure, blood oxygen saturation concentration)

When the blood pressure check module and the pulse oxygen concentration check module are attached to the patient and the table is driven, the blood pressure is checked once per minute, the pulse and oxygen concentration are checked once per second, and the patient is changed to the computer through the serial medium. Your blood pressure, pulse rate, and oxygen level are indicated.

How to return to the table when the pulse and blood pressure of the patient are abnormal during table operation

If the upper and lower limits of blood pressure and pulse rate according to the patient's condition are entered into the computer, the table will automatically return to its original state if the patient's blood pressure pulse is out of the upper and lower limits during table operation. In addition, in case of system error or emergency situation, it is possible to operate by installing emergency switch to return to remote control regardless of computer control.

The present invention has the following effects.

1) As the table is activated, the patient's blood pressure and pulse status can be continuously monitored according to the changing angle, so the patient's treatment status can be confirmed.

2) Since the patient's condition is known according to the maneuvering angle and speed of the table, the treatment angle and speed can be estimated later.

3) The angle and speed of tilting the table can be arbitrarily adjusted according to the condition or condition of the patient, so that severe patients who were previously difficult to apply can be used.In addition, when the patient has an abnormal symptom, the program is restored to its original state. As a result, stability was achieved.

A manufacturing method for arbitrarily adjusting the angle and the speed at which the tilt table is tilted.
