Intended to add moisture to breathing gases for administration to pediatric through adult patients weighing ≥ 10 kg >1 month in homecare, hospital, extended care and hospice.

There are two models of the Hudson RCI Disposable Humidifier. Both models have identical intended uses and modes of operation. One model has a 4 PSI pressure relief valve (referred to as model 3230) and the other has a 6 PSI pressure relief valve (referred to as model 3260). Regardless of device model, the disposable humidifier delivers humidified gases to the patient. Both models of the non-prefilled disposable humidity in water vapor form to respiratory gases delivered to patients to make the gases more comfortable to breathe. The disposable humidifier incorporates a pressure relief valve with an audible alarm at 4 psi or 6 psi. depending on the model selected. In both models, air is channeled through the water-containing bottle where it becomes humidified before exiting the device and being administered to the patient. The patient can influence the use of these devices by occluding or loosening secure connections. In cases where the patient is also the user, over or under filling the device and selection of incorrect oxygen percent concentration and gas input pressures may influence the use of the device.

The bubble humidifier is intended to add moisture to breathing gases for administration to patients >1 month in homecare, hospital, extended care and hospice. The bubble humidifier is a non-sterile device indicated for single-patient usage. The device is indicated for patients who require humidification of high flow supplemental breathing gases.

The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410 mbars) safety valve is an empty, disposable, non-sterile, not made with natural rubber latex, device intended to humidify breathing gas prior to delivery to a patient. The Salter Labs Bubble Humidifier (6-15 LPM) with 6 PSI (410mbars) safety valve is provided with a 6 pounds per square inch (PSI) safety valve and can operate within flow rates of 6 to 15 liters per minute (LPM). The device is used with various breathing gas sources (i.e., oxygen concentrators, gas cylinders and wall outlets) and provides connection for delivery of humidified breathing gas via face masks or cannulas, and use of optional oxygen tubing and water traps (face masks, 21 CFR 868.5580: nasal cannulas, 21 CFR 868.5340; oxygen tubing, 21 CFR 868.5860 and water traps, 21 CFR 868.5995 are 510(k) exempt). This device is a passive device and is not a cascade humidifier, is not heated and is not prefilled. The device is made of a humidifier bottle which is used to hold water during use, a lid which seals the humidifier bottle, an audible pressure relief mechanism to notify the user of a downstream occlusion and a diffuser located at the end of a PVC diffuser tube inside the humidifier bottle. The diffusor is designed to uniformly disperse the gas throughout the water. Both the bottle and lid are constructed to be easy to grip and reduce the chance of cross threading. The bottle is permanently marked with "minimum/maximum" water levels. The lid is marked with minimum source pressure, flow ranges and pressure value of the safety valve.

The pNeuton mini is intended to provide ventilatory support for critically ill patients who require the following general types of ventilatory support: - Positive pressure ventilation delivered invasively (via an ET Tube) or non-invasively (via a mask or nasal prongs) - CMV and IMV mode of ventilation with or without PEEP / CPAP - Provide oxygen or a mixture of medical air and oxygen

The pNeuton mini ventilator is a small, lightweight transport ventilator designed for use on patients from neonate to pediatric in size (400 gram to 25 kg). It is a time cycled, flow limited ventilator providing Continuous Mechanical Ventilation (CMV) or Intermittent Mandatory Ventilation (IMV). In these modes of ventilation, an adjustable inspiratory time, expiratory time and pressure is delivered to the patient. The patient is allowed to breath spontaneously between the mandatory breaths with little added work of breathing. A built-in PEEP / CPAP system can be set to provide expiratory positive pressure. The delivered oxygen is adjustable from 21 to 100 percent. The pNeuton mini ventilator is a pure pneumatic ventilator. Electrical power is not used. The ventilator operates from oxygen and medical grade air input pressures from 40 to 70 psi. The various control systems that manage the time controls, PEEP / CPAP, and safety systems / pneumatic alarms is powered with pure oxygen to maintain stability and accuracy. There are no electronic controls or software in this device. The device provides ventilation and CPAP support for the care of individuals who require respiratory assistance. The device is a restricted medical device for use by qualified medical personnel under the direction of a physician. The device may be used in prehospital environments, inter and intra-hospital patient transport, air and ground transport, and all areas of the hospital including the MRI (NOT for use in the presence of flammable anesthetics). The mini ventilator has been specifically designed for ruggedness and ease of use. The pNeuton mini ventilator uses accessories during normal operation. The primary accessory is a patient tubing circuit to attach the device to the patient. The patient circuit is a single-use disposable device. The patient circuit uses the same major component (expiratory valve) included with the predicate pNeuton Ventilator K043085 with smaller diameter hoses.

The Sevoflurane Vaporizer SV 953 is designed for use with the Servo Ventilator 900 and for vaporizing the liquid anesthetic agent sevoflurane in conjunction with the controlled administration of anesthetic gas mixtures during surgery.

The Sevoflurane Vaporizer 953 is an anesthetic vaporizer used together with Siemens Servo Ventilator 900 in anesthetic applications. It is a modification of the Siemens Vaporizers 950/951/952. The modifications made are: At the knob a scale for Sevoflurane is added. The scale indicates concentration values from 0.2% to 8%. The knob scale, label and filling mechanism, are yellow color coded. To reach the concentration values 8% the inside diameter of a capillary tube is 0.36mm instead of 0.30mm as in the other vaporizers.

The DHD Stealth Metered Dose Inhaler (MDI) Spacer (Without Integral Actuator) assists with the delivery of aerosolized medications when used in conjunction with commercially available Metered Dose Inhaler (MDI) canisters with their associated actuator elbows. In addition, for convenience, the MDI canister/elbow, may be stored inside of the Stealth when not in use (the spacer acts as the MDI canister/elbow holding chamber). Pilot is a one piece, silicone rubber face mask that may be attached to the Stealth MDI holding chamber as an interface between the Stealth MDI and the patient's face/mouth region.

The Pilot device is a mask attachment for the Stealth Metered Dose Inhaler (MDI) Spacer. The Pilot mask fits directly onto the Stealth MDI Spacer. Pilot is a single piece, injection molded, silicone rubber piece. It is intended for single patient use and may be disassembled from the Stealth MDI for convenient cleaning the device, by hand, in warm soapy water. The Pilot mask will be available in several sizes. and large masks. The mask sizes are designed to fit comfortably to a users face. The masks also include a tapered fitting designed to mate with the Stealth mouthpiece. The tapered fitting includes a small ledge which serves as a stop, preventing the mask from being advanced too far onto the Stealth mouthpiece.
