Tourniquet RS5300

Description

1- Purpose:

• Creating scientific and practical information about the use of the device and the way it works and the main components of the device.

2- Scope of application: 1-2- Operators, doctors, operators and personnel affecting the quality of the product and its after-sale services 3- Responsibility and authority: – None 4- Definitions: 1- None. 5- Description of the RAEEN brand tourniquet device – The tourniquet device is used to cut off the blood flow in the limbs and due to this characteristic, it is most widely used in orthopedic operating rooms, of course, in general and reconstructive operating rooms, as well as in cardiac operating rooms. (open heart operations to graft the leg vein to the heart) is also used. This device is used for children and adults and upper and lower limbs by connecting to cuffs of different sizes. The main components of the tourniquet device include a rotary pump, electric valve, air tank, microcontroller board, pressure data receiving board (panel board). This device uses a microcontroller to control the pressure inside the cuff based on the pressure set by the operator. The rotary pump in this system has been chosen because it has the least air leakage and the least noise, and the pressure is appropriate and necessary for the volume itself. It produces cuffs. The tank of the device actually acts like an accumulator and has the task of smoothing and uniforming the pressure of the produced wind and prevents sudden pressure shocks from entering the pressure transducer. The electric valve is used to empty the cuff at the end of the work and also to control the pressure during the work, and if the pressure increases for any reason during the work, this valve opens automatically and balances the pressure. The pressure data receiver board (Panel board) is responsible for recording the pressure required by the user, and in case of any change, it transfers it to the microcontroller board, and the micro system balances the pressure by commanding the pump and electric valve. Adjusts based on the operator’s request. Also, the micro board has the ability to record and store information and can be connected to receivers, including computers, mobile phones, etc., through Wi-Fi, and after entering the device’s special password, it can provide a report on the device’s performance during the patient’s surgery. This report is sent as a PDF file and can be printed and attached to the patient’s file. The display of the device has a 12-volt power supply and a graphic screen with a very high resolution, and it displays the information of the surgery including the set pressure, set time and operation time on the screen. For this device, a lifespan equal to 5 years is considered, and the documents related to the production of each product are archived for 5 years. It should be noted that the company is obliged to guarantee the device for one year and after-sales service for 10 years. *Technical specifications: – The device can adjust the pressure from 0-700mmHg. Of course, the maximum pressure used in the operating room for the patient is 550 mmHg. The acceptable error rate for calibration is 2% of the working pressure, and the product is finalized at a pressure of 500 ± 10 mm Hg. — The device has a timer and can be set from 0-300 minutes. In this case, the device sounds an alarm in the last 10 minutes so that the operator can increase the time if necessary. This alarm sounds again in the last 5 minutes. – If the patient’s operation ends before the scheduled time, there is a possibility of emptying the cuff in two continuous and staggered ways. in continuous discharge mode; The STOP button is installed on the device, which works with a delay, that is, the operator must hold his hand on the button for 2 seconds until the electric valve opens and the cuff is emptied. In step mode, the STOP/5 button is installed on the device, and this button is also delayed. In this case, 100 mmHg of the pressure inside the cuff is reduced every 5 seconds until the pressure reaches zero and the cuff is completely emptied. – There is a possibility to raise and lower the cuff pressure during operation and the operator can increase or decrease the pressure with the Pressure button. – It is possible to increase the time during operation, but it cannot be reduced, and this parameter is intended to increase the safety of the device. Because if the operator makes a mistake in the low times and reduces it, the cuff will be emptied quickly, so the design is based on the fact that the time can not be reduced during work.
