1. Pengenalan
The APEX Domus 4 Anti-Decubitus Mattress with Compressor is designed to provide effective pressure redistribution and relief for patients at high risk of developing pressure ulcers, or for the treatment of existing pressure ulcers up to Grade IV. This system aims to improve patient comfort and quality of life by preventing and managing skin breakdown associated with prolonged bed rest.
This manual provides essential information for the proper setup, operation, maintenance, and troubleshooting of your Domus 4 system. Please read it thoroughly before use to ensure safe and effective operation.
2. Maklumat Keselamatan Penting
Always follow basic safety precautions when using electrical products, especially when children are present. To reduce the risk of electrocution, burns, fire, or injury to persons:
- Read all instructions before using the mattress system.
- Do not operate the compressor if it has a damaged cord or plug, if it is not working properly, or if it has been dropped or damaged.
- Jauhkan kord dari permukaan yang dipanaskan.
- Do not block air openings or place on a soft surface where openings may be blocked.
- Jangan gunakan di luar atau beroperasi di mana produk aerosol (semburan) sedang digunakan atau di mana oksigen diberikan.
- Ensure the mattress is placed on a stable, flat bed frame.
- Regularly inspect the mattress and compressor for any signs of wear or damage.
- Consult a healthcare professional for appropriate patient positioning and care.
3. Komponen Sistem
The APEX Domus 4 system consists of the following main components:
- Alternating Pressure Mattress: Composed of individual air cells that inflate and deflate in an alternating pattern to redistribute pressure.
- Unit Pemampat: The pump that inflates and deflates the air cells, controlling the pressure and cycle time.
- Antimicrobial Cover: A protective, vapor-permeable, water-resistant, and flame-retardant cover for the mattress.
- Hos Udara: Connect the compressor to the mattress.
- CPR Valve: A quick-release valve for rapid deflation in emergency situations.
- Palam Pengangkutan: Used to maintain air in the mattress during patient transport or power outages.

4. Arahan Persediaan
Follow these steps to set up your APEX Domus 4 Anti-Decubitus Mattress system:
- Sediakan Kerangka Katil: Place the mattress on a standard bed frame. Ensure the bed frame is clean and free of sharp objects that could damage the mattress.
- Buka gulungan tilam: Carefully unroll the mattress on the bed frame with the air cell side facing up. Ensure the air hoses are positioned towards the foot end of the bed.
- Secure the Mattress: Use the adjustment straps located on the underside of the mattress to secure it to the bed frame, preventing slippage.
- Connect the Compressor: Hang the compressor unit securely at the foot end of the bed using its integrated hangers.
- Sambungkan Hos Udara: Connect the air hoses from the mattress to the air outlets on the compressor unit. Ensure a secure and tight connection.

Figure 4.1: Demonstrates connecting the air hoses from the mattress to the compressor unit.
- Plug in the Compressor: Plug the compressor's power cord into a grounded electrical outlet (AC 220-240V, 50 Hz).
- Inflasi Awal: Turn on the compressor using the On/Off button. The mattress will begin to inflate. Allow approximately 20-30 minutes for the mattress to fully inflate and stabilize before placing a patient on it.
5. Arahan Operasi
5.1. Panel Kawalan Selesaiview
The compressor unit features a control panel for adjusting settings and monitoring system status. Refer to the labels on your specific unit for exact button functions.
5.2. Pelarasan Tekanan
Adjust the pressure setting based on the patient's weight. The compressor allows for pressure range adjustment for patients weighing between 40 kg and 200 kg. Use the pressure adjustment dial or buttons on the compressor to select the appropriate setting for optimal pressure redistribution.
5.3. Therapy Modes
The Domus 4 offers three therapy modes:
- Alternating Pressure Mode: This is the primary mode, where air cells inflate and deflate in an alternating cycle (typically 10 minutes) to continuously redistribute pressure and stimulate blood flow.
- Mod Statik: In this mode, all air cells remain inflated to a constant pressure, providing a firm, stable surface. This mode is useful for patient transfers or when a stable surface is temporarily required.
- Anti-Shearing Mode: This mode helps reduce shearing forces on the patient's skin, often by slightly reducing pressure in certain areas or adjusting cell inflation patterns.
5.4. Fungsi Khas
- Max Firm: This function inflates all cells to maximum firmness, useful for patient care activities like dressing changes or transfers.
- Kunci Panel: Activates a lock function on the control panel to prevent accidental changes to settings.
- Mod Pengangkutan: When the compressor is disconnected, the mattress can maintain air for a period using the transport plug. Insert the transport plug into the air hose connection point on the mattress to seal the air within the cells.

- Fungsi CPR: In an emergency requiring CPR, pull the red CPR valve to rapidly deflate the mattress, providing a firm surface for resuscitation.

| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Mattress not inflating or losing air. | Air hoses not securely connected. Compressor not powered on. Leak in mattress or hoses. CPR valve open. | Ensure hoses are tightly connected. Check power cord and On/Off switch. Inspect mattress and hoses for punctures; repair if possible or contact support. Ensure CPR valve is closed. |
| Compressor making unusual noise. | Compressor unit not stable. Kerosakan dalaman. | Ensure compressor is hung securely and not vibrating against a surface. If noise persists, discontinue use and contact support. |
| Alarms sounding (Low Pressure, Power Failure, System Fault). | Low pressure: Leak or patient weight exceeding capacity. Power failure: Power disconnected. System fault: Internal error. | Check for leaks, adjust pressure setting. Ensure power cord is connected. For system fault, restart unit; if alarm persists, contact support. |
