Disclosed is an NO supply device including a main gas circuit to convey an NO/N.sub.2 mixture to a main output orifice which is designed to supply the inspiratory branch of a medical ventilator; and a backup circuit including a backup NO circuit including a backup NO line which is supplied with NO/N.sub.2 mixture, and a backup O.sub.2 circuit includes a main O.sub.2 line which is connected fluidically to the backup NO line in order to form a common line in fluid communication with a secondary output which supplies an NO/N.sub.2/O.sub.2 mixture designed to supply a manual breathing bag.

Disclosed is an NO supply device including a main gas circuit with NO/N.sub.2 flowrate controller controlled by piloting unit, and a backup circuit including a backup NO circuit and a backup O.sub.2 circuit. The piloting unit are configured in particular to control the NO/N.sub.2 flowrate controller in such a way as to regulate the flowrate of NO/N.sub.2 mixture in the main gas circuit and to direct the gaseous flow obtained in a downstream portion of the backup NO circuit connecting to the backup O.sub.2 circuit in order to form a common backup line including a backup outlet.

A reusable apparatus, such as a medical instrument or tool, is decontaminated by applying pressure waves with direct contact of the pressure wave applicator to the reusable apparatus in an open bath in a sufficient dosage to remove contamination but without adversely affecting the ability to reuse the apparatus.

A therapeutic vaporizer inhalation bag attachment system with an integrated valve is disclosed. The attachment system includes a body having a lumen extending between the two openings of the body, a bag coupling, and a valve positioned within the lumen. A method of using the inhalation bag attachment system is also disclosed.

Disclosed herein are embodiments describing nonrebreather facemasks for efficiently and comfortably delivering oxygen to patients. One embodiment describes a cup-shaped pliable facemask that is suited to cover and seal a patient’s nose, mouth, and cheeks within the cup-shaped facemask. Certain other embodiments describe an inlet tube outwardly extending from the facemask at an angle in line with the pathway of a patient’s nostrils to better provide oxygen directly into a patient’s nose. Other embodiments envision varying facemask’s stiffness for improved comfort and sealing against the patient’s face. While other embodiments envision a reduction in dead space of a facemask when worn by a patient to improve oxygen efficiency used by the patient.

Systems and methods for nitric oxide (NO) generation systems are provided. In some embodiments, an NO generation system comprises at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas. The electrodes have elongated surfaces such that a plasma produced is carried by the flow of the reactant gas and glides along the elongated surfaces from a first end towards a second end of the electrode pair. A controller is configured to regulate the amount of NO in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller. The one or more parameters include information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which the product gas flows.

A medical apparatus provides resuscitative therapy to a patient. The apparatus includes an electrocardiogram (ECG) input, a defibrillation output configured to provide an electrical defibrillation shock treatment, and an applicator body configured to provide active compression decompression therapy to the patient's chest. The applicator body includes a rescuer end configured for hands of the rescuer to press and pull on the applicator body, a coupling surface configured to adhere to the patient's chest to provide active compression decompression therapy, a capacitor, and processor(s) configured to receive and analyze the ECG signal of the patient, determine whether the patient is in need of defibrillation, and administer the defibrillation shock treatment to the patient.

Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

The resuscitator (1) includes a self-inflating squeeze bag (2) having an inlet opening accommodating an inlet valve arrangement (6) adapted to allow inflow of air into the squeeze bag and to prevent outflow of air from the squeeze bag through the inlet opening and an outlet opening accommodating a patient valve arrangement (8) adapted to allow outflow of air from the squeeze bag into the patient valve housing and adapted to prevent inflow of air into the squeeze bag through the outlet opening. The patient valve housing includes a patient connection port (9) for ventilation of a patient and a patient expiration outlet port (10) for outlet of exhaled gas from the patient valve housing to the surroundings. The resuscitator includes a filter arrangement (11) located upstream the outlet opening of the squeeze bag in order to filter air before reaching the patient valve arrangement from the squeeze bag.

A resuscitation management system may include a first accelerometer and a second accelerometer mounted on opposite sides of a resuscitation bag of a manual resuscitation device. The resuscitation management system may include a processing unit that may be configured to receive the measured acceleration vectors from the first accelerometer and the second accelerometer and then subtract the measured acceleration vectors from each other to obtain a resultant acceleration vector representing an acceleration magnitude and a spatial acceleration direction of compression/decompression of the resuscitation bag. The processing unit may then be configured to calculate the breathing parameters based at least in part on the acceleration magnitude and the spatial acceleration direction of compression/decompression of the resuscitation bag.
