Description

Brain damage prevention device for emergency recovery patients

The present invention relates to an apparatus for preventing brain damage in emergency recovery patients, and more specifically, by providing pneumatic pressure without a pump to facilitate extremity compression without noise and vibration, and to indirectly enhance cerebral blood flow through extremity compression to a patient undergoing emergency recovery It relates to a brain damage prevention device for emergency recovery patients that can minimize brain damage by maximizing oxygen supply to the patient.

In general, cerebral infarction is a type of stroke, and is a disease in which a part of a cerebral blood vessel is blocked, causing ischemic damage to brain tissue that is not supplied with adequate blood flow.

In the case of cerebral infarction, the primary treatment is to inject a thrombolytic agent such as ‘jugular vein thrombolysis’ or ‘carotid artery thrombolysis’ in order to proceed with treatment to open the blocked cerebral blood vessels.

In this procedure, a thrombolytic agent is injected into the body through an intravenous injection, and the thrombolytic agent spreads throughout the body and dissolves blood clots in the cerebral blood vessels so that cerebral blood vessel opening can be expected. Emergency surgery such as blood clot removal or vasodilation (stent) must be performed directly in the brain blood vessel.

In the case of injection of a thrombolytic agent, an invasive procedure such as insertion of a catheter into the femoral artery or carotid artery may cause pain to the human body. surgery has to be done

Accordingly, Patent Document 1 has been proposed, which can reduce pain caused by invasive procedures or surgeries and prevent stroke by regularly enhancing cerebral blood flow.

Such, Patent Document 1, four cuffs each capable of pressing the extremities; By having a blood pressure sensing module and a compression control module and including a control unit for controlling the cuff, the degree of compression of the compression pad can be controlled, thereby blocking blood flow to the extremities to indirectly enhance cerebral blood flow. Compared to the procedure, there are fewer side effects and complications, and the patient can be maintained autonomously in a comfortable state, thereby effectively enhancing cerebral blood flow.

However, there is inconvenient that air pressure must be provided and controlled through each pneumatic pump for each cuff worn on the extremities, and it is inconvenient due to the noise caused by performing air injection for control of the compression pad with an individual pneumatic pump Of course, there is a problem in that the target value of the pressure to be compressed to block blood flow cannot be accurately maintained due to each pulsation of the pump and blood pressure.

And, when applied to a stroke patient, there is a problem in that blood pressure in the cerebral blood vessels rises, thereby exposing to risk factors for cerebrovascular disease.

In addition, in any part of the body 100, the user recognizes an emergency and operates the exhaust valve 470 so that the patient can urgently escape from the cuff 200 to urgently release the pneumatic pressure of the cuff 200. An emergency exhaust button 130 may be further provided.

That is, when the user presses the emergency exhaust button 130 , the air pressure contained in the air bag 430 is urgently discharged through the exhaust valve 470 , and similarly, the air pressure hung on the cuff 200 through the exhaust valve 470 is also It is possible to easily escape by disassembling the cuff 200 with an emergency discharge.

In addition, in the above operation, even if the supply power is abruptly cut off due to a power outage, it is possible to urgently remove the pneumatic pressure to facilitate the emergency evacuation of the patient.

The device for preventing brain damage in emergency recovery patients of the present invention configured as described above generates pneumatic pressure through the pneumatic pump 170, rather than directly providing pneumatic pressure in the conventional pump type by the pneumatic pump, and in the air bag 430. In a state in which the pneumatic pressure is sufficiently stored, pneumatic pressure is provided at a constant pressure without pulsation to the cuff 200 worn on the patient's extremities, and the degree of compression is adjusted by providing the desired pneumatic pressure to the cuff 200 to the patient. more accurate and consistent.

That is, the air bag 430 is applied to the pneumatic control module 400 to prevent pulsation noise generated by providing pneumatic pressure to the cuff 200 directly through the pneumatic pump 170 to control the pulsation of the pneumatic pump 170 . can be filled

The pneumatic pump 170 controls the operation by generating pneumatic pressure from the moment power is supplied to the target pressure, and each air bag 430 provided in each pneumatic line 160 of the pneumatic control module 400 . The pneumatic pressure is stored in the systolic, and the first valve 410 and the second valve 440 are opened and closed by the PWM control of the controller 300 to measure the systolic blood pressure (blood flow cutoff pressure) and the pulse rate.

In other words, the pulsation noise generated from the pneumatic pump 170 and the pressure change of the cuff 200 due to the minute pulse of the human body transmitted through the cuff 200 overlapped, and the error of the systolic blood pressure (blood-blocking pressure) measurement value was overlapped. Since the pressure value transmitted through the cuff 200 is very small, the signal coming through the pressure sensor is amplified again and the algorithm of the control unit 300 removes the noise component through the filter. can be measured by

Through the first pneumatic sensor 420 and the second pneumatic sensor 460 of the pneumatic control module 400, the pneumatic pressure of the extremities is checked on the patient's extremities according to the systolic and diastolic phases, and the cuff through the control unit 300 The target value of pneumatic pressure provided in 200 may be bypassed from the extremities by adjusting the compression time according to the corresponding blood flow, thereby concentrating cerebral blood flow.

Meanwhile, a plurality of converters may be performed so that the power supply unit 310 to which the external power is connected can receive power and supply power corresponding to each component of the main body 100 to provide power of an appropriate voltage.

7 and 8, while the cuff 200 is worn on the patient's extremity, pneumatic pressure is provided to the cuff 200 by a signal from the controller 300, and then applied to the patient's systolic and diastolic phases at the set pressure The current state of the patient and the pneumatic state can be checked through the touch screen 320 by the control unit 300 according to the pneumatic pressure.

At this time, according to the condition of the patient, input the set values for the treatment time and the degree of compression, and while maintaining the pressure so that the detected target value does not exceed the set value, repeat the compression and relaxation according to the set time to increase blood flow to the extremities. By temporarily blocking it, blood flow to the brain can be increased to maximize oxygen supply.

As shown in Fig. 8, the user sets the time to maintain the compression by accurately grasping the condition of the patient undergoing the treatment according to the consultation of the doctor, the total treatment time, the rest time in the middle, etc. The range can be entered by the user according to the patient's condition.

The operating range of the device of the present invention for a patient is as follows.

The accuracy of the pulse rate (bpm) should be less than ±5% of the measured value, and in the measurement, using a standard product that meets the recommended standards of electronic medical devices, the patient was subjected to 3 compressions: 50, 80, and 110 in 1 minute. Measure the pulse rate and keep it within ±5% of the error range.

Next, in the case of the cuff 200, it is 50 mmHg or less between the minimum pressure and the maximum pressure so that the error range of the compression (mmHg) degree can be maintained within ±3 mmHg, and the pressure is applied in pressure steps, and the target value displayed in nanometers and the The range is limited by comparing the difference between the target values displayed on the electronic sphygmomanometer.

In the case of rapid exhaust, the time from the time of rapid exhaustion by operating the rapid exhaust valve 470 after expanding to a pressure of 260 mmHg for adults and holding it for 60 seconds to the point where the pressure decreases to 15 mmHg or less is 10 Design not to exceed within seconds.

That is, a stroke can be treated by applying pressure to the cuff 200 to block blood flow in the extremities to enhance blood flow to the brain.

Further, the compression setting of the cuff 200 may be set based on the measured blood flow blocking pressure of the patient.

By providing the present invention configured as described above, by providing pneumatic pressure without a direct drive pressurization pump, noise and vibration are minimized to facilitate extremity compression, and through extremity compression, cerebral blood flow is indirectly enhanced to provide oxygen supply to a patient in emergency recovery. It has the effect of minimizing brain damage by increasing it as much as possible.
