LAMPIRAN E.1
PETUNJUK PENGOPERASIAN OpenMCS
OpenMCS adalah alat stimulasi elektrik arus mikro. Stimulasi elektrik arus mikro menggunakan pulsa arus listrik dalam orde mikroampere sehingga pasien tidak akan merasakan efek langsung seperti halnya denyutan, rasa kesemutan, dll. OpenMCS hanya menunjukkan parameter-parameter yang dimiliki oleh pulsa elektrik, sehingga pengguna harus menyesuaikannya sendiri dengan tujuan penggunaan, untuk penelitian atau terapi.
1. Tampilan OpenMCS
Alat stimulasi arus mikro OpenMCS memiliki tampilan sebagai berikut. •
Tampilan depan dari OpenMCS
102
Penjelasan fungsi: Tombol pemilih jenis sinyal, berfungsi untuk memilih jenis-jenis sinyal terapi arus mikro yang akan dikeluarkan oleh OpenMCS. Lampu indikator catu daya adalah lampu yang menunjukkan kondisi OpenMCS dalam keadaan on atau off. Plug elektroda adalah tempat untuk menancapkan kabel elektroda yang dipasang ke pasien atau objek uji. Layar
tampilan,
berfungsi
untuk
menampilkan
parameter-
parameter sinyal arus mikro yang sedang dijalankan dan menampilkan pesan-pesan peringatan keamanan. Tombol pengatur kekuatan sinyal, berfungsi untuk menaikkan dan menurunkan kekuatan sinyal stimulasi Tombol pengatur frekuensi, berfungsi untuk menaikkan dan menurunkan frekuensi sinyal stimulasi Tombol pengatur lebar pulsa, berfungsi untuk menaikkan dan menurunkan lebar pulsa sinyal stimulasi
Plug charger
•
Saklar On/Off
Tampilan belakang OpenMCS Plug charger, berfungsi untuk menancapkan kabel dari charger baterai pada saat mengisi baterai Saklar on/off, berfungsi untuk menghidupkan atau mematikan catu daya alat OpenMCS
103
2. Langkah-langkah pengoperasian
Untuk
mengoperasikan
OpenMCS,
berikut
ini
adalah
langkah-langkah
penggunaannya secara benar. 1. Sebelum menghidupkan alat OpenMCS, terlebih dahulu pasang kabel elektroda ke plug elektroda. 2. Lakukan pemasangan elektroda secara benar kepada pasien. Jika elektroda tidak mengandung jelly, tambahkan jelly terlebih dahulu pada bagian yang akan ditempeli elektroda. 3. Hidupkan OpenMCS dengan menekan saklah on/off pada posisi I (menghadap ke bawah), selanjutnya pada layar tampilan OpenMCS akan menunjukkan informasi “TERAPI ELEKTRIK ARUS MIKRO”. 4. Pada saat layar LCD menampilkan informasi “SILAHKAN MEMILIH SINYAL STIMULASI”, tekan tombol pemilih jenis sinyal. Selanjutnya akan muncul tampilan nama sinyal yang sedang dipilih selama 1 detik kemudian diikuti dengan tampilan parameter sinyal yang sedang dipilih. 5. Lakukan penyetelan parameter sinyal sesuai dengan kebutuhan dengan menggunakan tombol pengatur kekuatan sinyal, tombol pengatur frekuensi, dan tombol pengatur lebar pulsa.
