Air & Oxygen Blender

An Air & Oxygen Blender is a Class II medical device that precisely mixes compressed medical air and oxygen to deliver controlled fractions of inspired oxygen (FiO2 21-100%) to patients requiring respiratory support. Essential in neonatal, pediatric, and adult critical care, these devices ensure accurate oxygen delivery via ventilators, CPAP systems, oxygen hoods, incubators, and transport systems. Operating at 40-60 psi inlet pressure, they maintain set FiO2 within ±2-5% accuracy across varying flow demands (0-120 L/min). Gas-specific DISS or NIST fittings prevent dangerous cross-connection between oxygen and air supplies. Available in wall-mounted, rail-mounted, portable, and ventilator-integrated configurations. Primary clinical applications include neonatal intensive care (oxygen hoods, incubators, nasal CPAP), pediatric and adult mechanical ventilation, non-invasive ventilation, and critical care transport. Critical safety requirements include verification of correct gas connections, regular calibration, leak testing, and immediate response to gas supply failure alarms. Indispensable for preventing both hypoxemia and oxygen toxicity (particularly retinopathy of prematurity in neonates) in patients requiring precise oxygen therapy.

Mucus Extractor

Mucus Extractors are sterile, single-use handheld suction devices designed for the rapid clearance of secretions from the oral cavity, pharynx, and trachea, with distinct configurations for neonatal and adult populations. Neonatal/infant extractors feature soft, flexible, small-diameter tips with low suction capacity (30-60 mL) to minimize trauma to delicate airways. Adult/universal extractors (Yank Auer) are rigid, large-bore, angled devices with multiple suction eyes and high-flow capacity (150-300 mL) for rapid clearance of blood, vomitus, and thick secretions. Select models incorporate sterile specimen traps for collection of respiratory secretions for microbiological analysis. Critical safety requirements include strict limitation of suction duration (≤10 seconds; ≤5 seconds in neonates), avoidance of excessive suction pressure (neonates ≤80 mmHg), use of non-traumatic multiple-eye tips for vulnerable patients, and absolute single-use protocol. An indispensable airway device in neonatal resuscitation, pediatric care, emergency medicine, and perioperative settings.

Oxygen Concentrator

An Oxygen Concentrator is a Class II medical device that delivers 90-95% pure supplemental oxygen to patients with chronic hypoxemia using pressure swing adsorption (PSA) technology to concentrate oxygen from room air. Available as stationary/home units (10-30 kg, 0.5-10 L/min continuous flow) for long-term oxygen therapy (LTOT) and portable/ambulatory units (1-10 kg, 0.5-3 L/min pulse-dose or continuous flow) for active patients requiring mobility. Features include oxygen purity monitoring with alarms, digital flow control, hour meters, washable filters, and (for portable units) rechargeable batteries, FAA approval for travel, and pulse-dose delivery to conserve oxygen. Primary clinical indications include COPD, pulmonary fibrosis, cystic fibrosis, and other chronic respiratory conditions with resting, exertional, or nocturnal hypoxemia (PaO2 ≤55 mmHg or SpO2 ≤88%). Essential for home-based oxygen therapy, enabling patients to maintain independence, reduce hospitalizations, and improve quality of life. Critical safety precautions include NO SMOKING in the oxygen environment, keeping away from heat sources and open flames, proper electrical safety, regular filter cleaning, and having backup oxygen for power outages.

Suction Catheters

Suction Catheters are sterile, single-use flexible tubes designed for aspiration of pulmonary secretions from the airways of intubated, tracheostomized, or spontaneously breathing patients unable to clear their own secretions. Available in French sizes 5 Fr-18 Fr, with whistle-tip or coude configurations, single or multiple eyelets, and thumb-controlled suction valves. Open suction catheters are single-pass devices requiring strict sterile technique and immediate disposal. Closed (in-line) suction catheters are enclosed in a sterile sheath, permitting suctioning without ventilator disconnection, maintaining PEEP, and reducing aerosolization of pathogens—essential for high-frequency ventilation, ARDS, and airborne precautions. Critical safety parameters include catheter gauge not exceeding one-half the endotracheal tube internal diameter, suction duration ≤15 seconds, and vacuum pressure ≤150 mmHg. Proper technique prevents hypoxemia, mucosal trauma, and ventilator-associated pneumonia.
