Special Helmet Innovation Helps Covid-19 Patients Breathe

RADARSOLO.ID – Even though the number of positive cases of Covid-19 is starting to decline. But the pandemic is not over yet. Not wanting to be careless in facing this pagebluk, this group of students created a special helmet to help the breathing of Corona patients.


Covid-19 patients with moderate to severe symptoms are prone to respiratory problems. Usually, patients who feel the disorder are immediately referred to the hospital. As a result, not a few hospitals are running out of non-invasive breathing apparatus. The impact of the surge in the number of patients hospitalized.

“Seeing this phenomenon, we took the initiative to create a medical respiratory aid breakthrough. Helmet shape. his name, continuous positive airway pressure (CPAP) based on IoT. This tool is expected to make it easier for medical personnel to treat Covid-19 patients. At the same time overcoming the lack of breathing apparatus for Covid-19 patients in Indonesia,” said student of the Faculty of Engineering, Universitas Sebelas Maret (UNS) Rizqi Husain Alfathan to Jawa Pos Radar Solo, yesterday.

Husain, as he is known, along with other students, Bioma Cakrawala, Muhammad Dzaky Musyaffa, Azzahra Fadhlila Aulia Nisa, and Rani Dwi Larasati in making this innovation. The CPAP helmet is a device that can be used to maintain positive pressure in the neonate’s airway during spontaneous breathing.

“This CPAP helmet has been extensively researched by various parties. But there are still many shortcomings. So, my team and I have an innovation to make a CPAP helmet that is equipped with an oxygen sensor, a MAX 30102 sensor, and is already based on the Internet of Things (IoT),” he explained.

Why should it be equipped with an oxygen sensor? Husain explained, this is useful for measuring the level of oxygen that enters the CPAP helmet interface. While the function of the MAX 30102 sensor added in this tool is to measure oxygen levels or oxygen saturation stored in the patient’s blood. This tool is made based on IoT. So using this tool is quite easy.

“It can ease the burden on the medical team so they don’t always check the oxygen levels in the patient’s body. Because the medical team can monitor the oxygen levels contained in the patient’s blood through smartphone,” he continued.

Using this tool is very easy. First, attach and attach the CPAP helmet to the patient’s body. Then, attach the output line circuit to the CPAP helmet. Next, connect the micro controller box to the oxygen sensor. Finally, connect the micro controller to the smartphone via bluetooth.

“There are several advantages of our CPAP helmet. This tool can beassembly dan maintenance easily and quickly. This tool can also be used many times by sterilizing CPAP components. Except for the CPAP tube and the patient’s neck brace. Must be replaced when reused. Most importantly, this tool is based on IoT,” he explained.

Husain and his team made this tool made of 30 cm (cm) x 85 cm polypropylene plastic for the manufacture of tubes. PLA filament for 3D printing CPAP helmet components. 2.2 cm nylon for conduit pembuatan input and output CPAP helmet. While the microcontroller circuit uses an OOM202 oxygen sensor, Arduino Nano, ADS1115, HC 05, 18650 battery, and jumper cables.

“The manufacturing process begins with making a sketch or a rough idea of ​​this tool. After getting the sketch, we started designing this tool using 3D engineering drawing software. After that, the fluid flow analysis was tested using the computational fluid dynamics (CFD) method. The design of this tool is done repeatedly to improve the flow of oxygen into the CPAP helmet,” he explained.

The design of the CPAP helmet made by Husain et al is claimed to have been simplified into three parts. Consists of tube, channel input, and channel output. Then it is equipped with an oom202 oxygen sensor and a max3010 oxygen saturation sensor. It is located on the outside of the CPAP helmet. Meanwhile, to convert analog signals to digital, a controller circuit is made. Consists of Arduino nano, HC05 module, and ADS1115.

“This application that we made uses the help of the HC-05 bluetooth module. We put it on the CPAP helmet which will be used by the patient. Then the medical team can control the patient’s oxygen saturation state and oxygen levels on the CPAP helmet interface via an application on a cellphone,” he added.

One of the team members from the Faculty of Medicine UNS Azzahra Fadhlila Aulia Nisa said that there are several application features offered by this tool. Besides being able to monitor oxygen levels at the CPAP helmet interface. This tool is also able to monitor oxygen levels in the patient’s blood.

“This application that we made also has advantages. Can be used by anyone. Don’t use the internet. Doesn’t take up much internet. And able to monitor the CPAP helmet and the patient’s blood in real time,” he continued.

Zahra claims that the manufacture of this CPAP helmet has met health standards. This tool has been simulated several times and the result is that the pressure generated by the CPAP helmet has exceeded the clinical value.

Hopefully this tool can be realized as a breathing apparatus. To help overcome the current problems of Covid-19 patients,” he said. (aya/bun/dam)
