Description

Medical automatic flow control method and device using the same

The present invention relates to an automatic flow control method for medical use and an automatic flow control device using the same, which receives the color of discharged fluid from an RGB color sensor as a value and calculates the motor speed of a peristaltic pump with an infusion bag using a PWM value calculated based on this value.

Various injections such as Ringer's solution administered to patients before and after surgery or during recuperation should be continuously administered in a certain amount for a certain amount of time according to accurate diagnosis and prescription by a specialist. A drug injected into a blood vessel through an injection needle is usually stored in a Ringer's bottle and continuously supplied from a position higher than the patient by gravity or by using contraction pressure of a pressure bag.

The roller clamp, which adjusts the cross-sectional area of the tube, is the most commonly used fluid treatment device. Although the price is cheap, it is difficult to accurately adjust the flow rate because it depends on experience, and there is a high possibility of error. In the case of a flow regulator that adjusts the length of the internal passage, it is more expensive than a roller clamp, but there is a problem that the speed displayed on the device and the actual speed are displayed differently for each patient due to various variables.

An infusion pump that injects drugs by applying pressure to an infusion bag or a syringe pump that injects drugs by applying pressure to a syringe is used in emergency rooms, operating rooms, or patients with chronic diseases who require continuous drug injection. These are very expensive pieces of equipment when it comes to precise flow control. Sometimes it is necessary to adjust the infusion fluid based on the information of the discharged fluid. In the case of general infusion, an infusion pump is used when the patient is infused with more than 100 cc/hr.

Korean Patent Laid-open Publication No. 10-2005-0099952 proposes a structure in which a capillary tube is inserted into each of a plurality of branched soft tubes to adjust the flow rate by selectively blocking a plurality of soft tubes with pressure while maintaining a constant amount of drug inflow into each tube. has been However, there is a problem in that it is difficult to accurately control the flow rate rather than the structure in which the flow rate is automatically adjusted by the sensor as in the present invention.

First, the flow measurement sensor unit 10 measures the flow rate of the moving drug and the flow rate of the bodily fluid flowing out of the body organs. The flow measurement sensor unit 10 measures and provides flow rate information flowing from each of the peristaltic pump site, patient surgical site, and waste bag site.

More specifically, as shown in FIG. 5, the flow measurement sensor unit 10 is attached to the outside of the tube to measure the strain of the tube according to the change in flow rate, and senses the internal pressure using this. In addition, it is ultimately configured to measure the internal flow rate.

The correlation between the minute strain change and the internal pressure is calculated as an elastic-mechanical relational expression by the elastic modulus of the tube, which is the mechanical property of the elastic tube, the diameter (d) of the tube, and the thickness (t) of the tube.

In addition, the peristaltic pump is controlled by Arduino's PWM (pulse width modulation) method, and allows injecting a drug of 100 to 5,000 cc/hr.

Next, the speed control unit 40 determines that the system is stopped when the PWM (pulse width modulation) calculated by the formula control unit 30 exceeds a set value, and controls the speed of the peristaltic pump. The speed control of the peristaltic pump controls the speed of the peristaltic pump by executing a '0' command to the PWM of the motor.

More specifically, whether or not the set value is exceeded determines whether pulse width modulation (PWM) exceeds 255, and when the set value is exceeded, the system is judged to be stopped to control the speed of the peristaltic pump. The set value of 255 means the maximum value of PWM, and may vary depending on the performance of the peristaltic pump.

Next, the output unit 50 outputs an error message or the color, pulse width modulation (PWM), and flow rate of the fluid or blood. The output unit 50 is provided so that a computer or portable terminal that transmits and receives data with the output unit 50 can output.

Next, the transceiver 60 transmits the color, pulse width modulation (PWM), and flow rate data of the infusion or blood, and checks whether or not they are transmitted. The transceiver 60 transmits and receives the data to and from a computer or mobile terminal.

The transceiver 60 provides necessary data using a Bluetooth or Wi-Fi module and provides functions such as stopping system operation in an emergency.

Next, the data control unit 70 terminates the manual system and the entire system, or executes the peristaltic pump operation stop button or the PWM (pulse width modulation) control button.

More specifically, the stop button sets the PWM to 0 to stop the peristaltic pump, and the control button increases or decreases the speed of the peristaltic pump by increasing or decreasing the current PWM value.

The operation stop button and the control button are displayed by a computer or portable terminal, and when the operation stop button is selected, yes/no is presented to be selected, and when the control button is selected, yes/no is presented to be selected. do.

Next, the increase/decrease control unit 80 checks whether or not to increase by executing the PWM (pulse width modulation) increase/decrease button of the Arduino.

The increase/decrease button displays 'increase' and 'decrease' buttons on the portable terminal, or presents an arrow shape so that speed increase/decrease can be selected.

The power supply unit 90 is operated by a dry battery and a small battery, and is provided to be lightweight and highly portable.

Next, in the third step (S30), the RGB sensor unit 20 detects the color of the flow rate and converts it into a color value.

As described above, the RGB sensor unit 20 irradiates light through a white LED and detects a color using light reflected from an object. When clots or blood are detected in the tube, a relatively high LED value is received. This color is measured by minimizing components of the infrared region entering the RGB sensor unit 20 because an infrared cut-off filter is coated thereon.

Next, in the fourth step (S40), the formula control unit 30 substitutes the PWM (pulse width modulation) relational expression of Arduino according to the color value confirmed in the third step (S30).

Next, in the fifth step (S50), the formula control unit 30 determines whether the PWM (pulse width modulation) according to the color value exceeds an arbitrary value set by the relational expression derived in the fourth step (S40). check whether

Next, in the ninth step (S90), the formula control unit 30 checks whether or not the body excreted fluid calculated in the eighth step (S80) exceeds a predetermined maximum value of the flow rate.

Next, in step 10 (S100), when the liquid excreted from the body is equal to or less than the maximum value of the flow rate in the ninth step (S90), the output unit 50 displays the color of the liquid excreted from the body, PWM (pulse width modulation) and output the flow rate.

Next, in step 11 (S110), the transceiver 60 transmits the color, PWM (pulse width modulation), and flow rate data of the liquid output from the body output in step 10 (S100), and confirms whether or not the transmission has been performed. .

Next, in step 11-1 (S111), when the data is not transmitted in step 11 (S110), the data controller 70 stops the manual system and terminates the entire system.

Next, in the twelfth step (S120), when the data is transmitted in the eleventh step (S110), the data controller 70 executes the peristaltic pump operation stop button.

In one embodiment of the invention, the invention may be used for bladder irrigation.

The bladder washing process is important for treating and preventing inflammation by washing away blood clots and pus in the bladder with a washing solution after urological surgery and injecting drugs. During bladder irrigation, a Foley catheter is inserted into the urethra to inject or discharge drugs, urine, and washing fluid. The nurse manually proceeds from the supply of the washing solution to the comparison of the amount discharged, and it is divided into intermittent washing that supplies a large amount of washing solution in a short time or continuous washing process using an infusion set. This process is generally carried out until the discharged washing liquid becomes clear, and it takes several hours at the longest, and continuous confirmation is required.

Therefore, direct execution of all processes acts as an increase in the workload of the medical personnel in charge and a burden on the patient, and it is possible to automate these series of processes by applying the device of the present invention to bladder washing.

More specifically, FIG. 2 shows a case in which the present invention is applied to bladder washing after bladder surgery of a patient, and the configuration of the present invention when used for bladder washing can be described as follows.

First, drugs including fluid or lavage fluid are injected through a peristaltic pump. The RGB sensor unit 20 detects the color of the flow rate of bodily fluid flowing out of the bladder and converts it into a color value of 2, and the flow measurement sensor unit 10 measures the flow rate of the moving drug at 198 cc/hr. Next, when the formula control unit 30 calculates the PWM value of Arduino as 157 by substituting it into the relational expression using the color value 2, and determines that the PWM value is 255 or more, the speed control unit 40 interlocks Command the PWM of the pump to zero. Next, when the flow measurement sensor unit 10 measures the flow rate of the body fluid flowing out of the bladder as 50 cc/hr, the formula control unit 30 calculates the fluid discharged from the body as 148 cc/hr. Next, when it is determined that the body excreted fluid is equal to or less than the set maximum value of 150 cc/hr, the output unit 50 changes the color, PWM (pulse width modulation), and flow rate of the excreted fluid from the body through a computer and a portable terminal. output, and the transmission/reception unit 60 checks whether the color, pulse width modulation (PWM), and flow rate data of the liquid excreted from the body are transmitted. Thereafter, when confirming that the data has been transmitted, the data control unit 70 executes the operation stop button of the peristaltic pump and stops the system in the portable terminal when the operation stop button is executed.

Next, the present invention can be used for intravenous infusion. However, in the case of intravenous infusion, the speed of the fluid injected into the vein can be adjusted through speed control without the need to use the RGB sensor unit 20 .

Intravenous infusion is required in many situations, including nutrition, emergency, and blood transfusion. Intravenous infusion requires accurate dosing, infection, and speed control because sudden infusion of a large amount of fluid causes overload in the circulatory system.

Therefore, if the present invention is used during intravenous infusion, contamination can be reduced and speed control can be conveniently performed.

By means of solving the above problems, the present invention can provide a medical automatic flow control device capable of injecting a drug through a peristaltic pump and adjusting the amount of the drug injected through an RGB color sensor.

In addition, the present invention accepts the color of the discharged liquid as a value from the RGB color sensor and adjusts the speed of the peristaltic pump motor attached to the infusion bag with the PWM value calculated based on this value, so that the amount of drug injected can be easily adjusted.

In addition, the present invention can provide medical information to a medical staff or user by interworking with a mobile phone through a Bluetooth module.

As such, it will be understood that the technical configuration of the present invention described above can be implemented in other specific forms without changing the technical spirit or essential features of the present invention by those skilled in the art to which the present invention pertains.

Therefore, the embodiments described above should be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and the meaning and scope of the claims and their All changes or modified forms derived from equivalent concepts should be construed as being included in the scope of the present invention.
