Sistem Alarm Penggantian Cairan Infus Berbasis Mikrokontroler menggunakan Wireless

Abstract

<p class="Abstrak">Terdapat kasus rumah sakit yang memiliki jumlah pasien yang lebih banyak daripada perawat jaga sehingga dapat menyebabkan kelalaian dalam pengontrolan sehingga menyebabkan adanya masalah pada sistem organ dikarenakan penggantian cairan infus dilakukan terlambat atau bahkan cairan infus tidak menetes akibat kesalahan alat, sehingga harus dibuat sistem notifikasi untuk pengontrolan cairan infus di rumah sakit menggunakan mikrokontroler dan terhubung secara <em>wireless</em> ke ruang perawat. Perancangan sistem alarm infus ini menggunakan photodioda dan inframerah sebagai pendeteksi ada tidaknya cairan infus yang menetes, serta untuk menghitung volume cairan infus. Sistem alarm ini akan terhubung ke sebuah <em>buzzer</em> yang terdapat di ruang jaga secara <em>wireless</em> dengan tipe nRF2401L dengan menggunakan sistem minimum arduino nano 328p. Sistem catu daya menggunakan baterai lithium yang dapat di charge melalui USB sehingga alat ini menjadi <em>portable</em> dengan bantuan modul TP4056. Alarm akan berbunyi pada dua kondisi yaitu ketika cairan tidak menetes dan ketika cairan <100 mL. Hasil pengujian sistem untuk perhitungan tetesan/menit memiliki korelasi 0.9866 yang berarti korelasi sangat kuat dan linier antara nilai ukur dan nilai hitung. Sementara untuk pengujian sistem alarm berfungsi dengan baik ketika cairan tidak menetes dalam waktu 7 s alarm berbunyi dan ketika cairan <100 mL alarm juga akan langsung berbunyi. Jarak efektif untuk pengiriman data melalui wireless yaitu pada jarak 4 m - 6 m.</p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Judul2"><em>Some hospitals that have a larger number of patients than nurse duty so as to cause negligence in controlling causing problems in the organs system due to fluid replacement is done late or even infusion fluid does not drip due to faulty tool, so we created notification system for control hospital infusion fluid using a microcontroller and wireless connected to the nurses room</em><em>. </em><em>The design of this infusion alarm system using photodioda and infrared as a detector of the presence of infusion fluids that drip, as well as to calculate the volume of intravenous fluids. This alarm system will connect to a buzzer contained in the duty space wirelessly with type nRF2401L using a minimum</em><em> system</em><em> arduino nano 328p. The power supply system uses lithium batteries that can be charged via USB so that the device becomes portable with the help of TP4056 module. The alarm will sound in two conditions when the liquid does not drip and when the liquid is <100 mL. System test results for the calculation of droplets / minute has a correlation of 0.9866 which means the correlation is very strong and linear between the value of measuring and calculating value. As for testing the alarm system works well when the liquid does not drip within 7 s, alarm already sounds and when the fluid <100 mL alarm will immediately sound. Effective distance for sending data via wireless which is at a distance of 4 m - 6 m.</em></p><p class="Abstrak"><em><strong><br /></strong></em></p>

Sistem Monitoring Cairan Infus Berbasis IoT Menggunakan Protokol MQTT

“…error value (%) = original weights − system weight original weights × 100% (1) with original weight signifies the weight of infusion fluid when measured with a digital balance, while the system weight signifies the weight of the infusion fluid when measured with the system that has been made…”

“…As a medical device, infusion, under certain conditions, is used to replace body fluids and balance electrolytes, besides functioning as a medium for treatment through fluids channeled directly into blood vessels. Currently, infusion devices are generally still used manually, requiring medical workers to constantly monitor the condition of these devices, which certainly consumes more energy and time [1].…”

“…Running out of intravenous fluids may threaten the patient's life since the intake of fluids to replace electrolyte fluids in the body and the intake of medicinal fluids into the blood vessels stop. Therefore, there is a need of technology to monitor infusion fluids remotely and in real time [1], [4].…”

“…Previous study created a wireless microcontroller-based infusion fluid replacement alarm system using photodiode and infrared sensors placed on infusion fluid bottles. The data were processed by the microcontroller, then medical staff would receive notifications of infusion conditions through an alarm in the nurse station [1]. In another study, a medical infusion system monitoring tool was created using ZigBee, which is one of the communication protocols on a wireless sensor network, with photodiode and infrared sensors to monitor several volumes of infusion fluids.…”

“…Several studies on infusion monitoring systems that have been conducted have advantages and disadvantages. In the study on the wireless microcontroller-based infusion fluid replacement alarm system by using a notification from a buzzer placed in the nurse station has succeeded in monitoring the presence or absence of infusion droplets and volume using photodiode and infrared sensors [1]. Unfortunately, IoT was not implemented in this system since it used the nRF2401L module so that the monitoring distance was limited to the range of 4 m -6 m. In addition, the notification of infusion conditions still used the buzzer so that the staff could not observe the remaining infusion volume.…”
