HAMILTON-H900 Humidifier with Built-In Condensation Prevention Technology

HAMILTON H900 HAMILTON H900 Humidifier with Built In Condensation Prevention TechnologyHamilton Medical (Bonaduz, Switzerland) has unveiled a new clinical humidifier. The device was designed to reduce the number of cables used, to integrate components into a simpler system, and to help control condensation and “rain-out” within the tubing.

ires HAMILTON H900 Humidifier with Built In Condensation Prevention TechnologySince a cool tube having warm humid air moving through it will form condensation on its walls, the device integrates heating coils within the tubing so that the temperature of the air stays constant throughout its journey. The device can be controlled through a touch interface or can also be connected and operated through a compatible ventilator.

The HAMILTON‐H900 comprises only two components, which are delivered preassembled and ready to use: The wall‐heated breathing set including the new all‐in‐one connectors, integrated temperature probe, water refill tube, Y‐piece, and water chamber, and the humidifier base with the user interface and the heating plate. This saves time, increases efficiency, and facilitates the handling of the humidifier, as well as reducing the risk of contamination. With no need to worry about extra cables to connect or disconnect anymore, the caregiver only needs to slide the water chamber into the humidifier and connect the breathing circuit to the patient.

Due to the ergonomic design, the user interface can be easily seen and operated from a standing position, and provides all the information the caregiver needs at a glance. The large, high contrast LCD display provides excellent readability, even in direct sunlight. Alarms are displayed with self‐explanatory icons on the LCD display, and can be heard and seen from afar thanks to the bright alarm lamps and audible alarm.

Evoked Potential Assessment Device Prevents Arms and Legs from Falling Asleep During Surgery

Evoked Potential Assessment Device Prevents Arms and Legs from Falling Asleep During Surgery

All of us have fallen asleep on an arm or sat too long on a twisted leg only to get up and feel like the limb itself has fallen asleep. Nerves can get stretched and compressed, and blood vessels squeezed, and, if a person’s position is not corrected soon enough, it can lead to permanent tissue damage, compartment syndrome and such . This scenario can happen during surgery, but since the patient is anesthetized and can’t feel, the situation usually goes undetected and can lead to significant damage. A new product from SafeOp, a company out of Hunt Valley, Maryland has received FDA clearance for “positioning effect” monitoring without having a dedicated nneurophysiological monitoring team.

The Evoked Potential Assessment Device (EPAD) uses SSEPs (somatosensory evoked potentials) to detect abnormal nerve signaling that is indicative of poor patient positioning. The output of the device is sent wirelessly via Bluetooth to a tablet that can be hung beside the patient to allow a live view of the positioning effect so that clinicians can move the patient and prevent intra-op damage.

Puritan Bennett 980 Ventilator with Proportional Assist Ventilation Plus Tech Cleared in U.S.

Puritan Bennett 980 Ventilator with Proportional Assist Ventilation Plus Tech Cleared in U.S.

The FDA has cleared Covidien‘s Puritan Bennett 980 Ventilator  for use with neonatal patients, children, and adults. The device features Proportional Assist Ventilation Plus (PAV+) technology licensed from University of Manitoba in Canada that provides smarter pumping to optimally synchronize with every patient. This will hopefully allow many patients to get off the ventilator earlier, something studies of proportional-assist ventilation have already indicated.

“We believe mechanical ventilation should be natural enough to enable patients to breathe on their own more quickly,” said James E. Willett, vice president and general manager, Respiratory Solutions, Covidien. “The Puritan Bennett 980 ventilator provides clinicians with a simple, safe and smart way to care for patients.”

AlertWatch Anesthesia Info System for Actionable Display of Patient Data

AlertWatch Anesthesia Info System for Actionable Display of Patient Data

During surgery, anesthesiologists and nurse anesthetists have a lot of live parameters to keep an eye on, besides all the pre-op patient information that was gathered earlier. Moreover, all these data are typically presented using charts and numbers, requiring quite a bit of interpretation to make sense of it all. Dr. Kevin Tremper, Chair of the Department of Anesthesiology at University of Michigan, Ann-Arbor had the idea of bringing all this information together into one intuitive interface that would display it in a way that provides a effective understanding of patient status. This idea turned into a spinoff company called AlertWatch that has just been awarded FDA clearance for its new software.

Data is displayed alongside an abstracted animation of the patient’s cardiopulmonary system with live and pre-op readings positioned for quick understanding. This was motivated by airplane consoles that have changed significantly over the years to help pilots make smarter and faster decisions.

Hamilton Medical’s MRI Compatible Ventilator Cleared in U.S.

Hamilton Medical's MRI Compatible Ventilator Cleared in U.S.

Hamilton Medical out of Bonaduz, Switzerland has been given the green light by the FDA to bring its MR compatible ventilator to the U.S. The HAMILTON-MR1 features a gaussmeter that displays the magnetic field’s shape and strength around itself, helping clinicians to safely position the unit near the MRI scanner. If the device detects a strong magnetic field, it sounds an alarm to get it out of the magnet’s effective range.

The main unit is intended to be located at a magnetic field strength of 500 gauss or less without affecting the imaging of the scanner. Even when not ventilating, the HAMILTON-MR1 always monitors the magnetic field around itself since it can reside in the scanner room waiting for patients on standard ventilators coming from the ICU.

Automatic Device for Faster and Safer Tracheotomies

Automatic Device for Faster and Safer Tracheotomies

A tracheotomy is an emergency procedure applied to somebody with an obstructed airway, where a trained bystander makes an incision in the victim’s neck and inserts a tube to restore ventilation. While a relatively straightforward procedure for those with training and experience, it can have complications, or worse: if nobody around the suffocating victim is trained to perform it in the few seconds before loss of consciousness.

Researchers at the Universidad Politécnica de Madrid (UPM) and Universidad Autónoma de Madrid (UAM) have designed and patented a more user-friendly solution. Their device easily identifies the trachea, and makes a clean incision that allows for future surgeries when medical attention arrives.  It does so by assisting the user in locating the neck and trachea, adjusting the preload of the shot of the needle, making the incision for an alternative airway, dilating the new airway, and maintaining the airway by electrical and pneumatic means.

EarlySense 2.0 Wireless Patient Monitor Now With Advanced Motion Detection, Reporting Capabilities

EarlySense (Waltham, MA) won FDA approval for the new version of its bedside monitoring system that wirelessly detects patients’ heart rate, respiration rate, as well as motion. EarlySense 2.0 now features improved patient monitoring by giving more focus to fall prevention, essentially detecting patient motion and predicting that someone might be trying to get up and about. This is accomplished through the new “Rest Indicator” that can warn clinicians of signature movements before the patient is even able to sit upright.

Additionally, the system is able to keep track of response times by staff to the alarms that it issues, and provides reports based on those readings.
