The present invention relates to a nasal oxygen cannula, which has a simple and economic design that reduces drug wastage and allows the effective use time to be measured in order to effectively monitor oxygen therapy treatment in patients with spontaneous breathing. Structurally, the cannula is formed by a mechanical system that is only activated when it comes into physical contact with the patient’s columella, and an electronic component that allows the real use time of the device to be measured by means of an electric actuator that triggers an electric pulse the moment the cannula is in place on the user.

Appl.No PCT/EP2020/069983 Applicant HAMILTON MEDICAL AG Inventor LAUBSCHER, Thomas
The present invention relates to a method for determining the functional residual capacity (FRC) of a patient's lung, comprising the following steps: - supplying a first inspiratory breathing gas having a first proportion of a metabolically inert gas, - supplying a second inspiratory breathing gas having a second proportion of the metabolically inert gas, - determining any arising volume difference, which represents a difference in volume between a volume of inspiratory and of expiratory metabolically inert gas for a determination period, - determining the functional residual capacity (FRC) taking into account the volume difference and a proportion difference between a first proportion quantity and a second proportion quantity, which represent the first proportion and the second proportion of the metabolically inert gas, respectively. According to the invention, the method comprises the following further steps: - determining a base difference (74), which represents a difference between a tidal volume of inspiratory metabolically inert gas and of expiratory metabolically inert gas, and wherein the functional residual capacity (FRC) is determined on the basis of a corrected volume difference and the proportion difference, the corrected volume difference being calculated by taking into account the base difference when determining the volume difference.

The present invention describes methods for obtaining functionalized polymeric surfaces (MPn-PSm) from polymers or copolymers with appropriate functionalizations (X), which can be a halogen or a leaving group, such as polyvinyl chloride (MP1) and (Chloromethyl)polystyrene-Merrifield (MP2), and curcumin photosensitizers (PS1), meso-Tetra(aryl)porphyrins, halogenated and functionalized chlorins and bacteriochlorins with nucleophilic groups (PS2). The structures of all of the photosensitizers in the present application incorporate the functional group (Y), which is an OH, SH or NH2 nucleophile. The application also describes the covalent bonding process of the photosensitizers PS1-PS3 to the functionalized polymeric materials MP1-MP2 by means of a nucleophilic substitution reaction to prepare the MPn-PSm products. The formed products prevent microbial proliferation, which can cause the serious infections that are one of the main causes of death in patients using these devices.

Appl.No PCT/US2020/042287 Applicant CONVERGENT ENGINEERING, INC. Inventor EULIANO, II, Neil Russell
A novel clinical decision support system (CDS) helps the clinician setup, maintain, and interpret aesophageal pressure measurement. The esophageal pressure CDS (Pes CDS) would remind the clinician to do an occlusion test whenever the balloon is first inserted or changes dramatically. It could monitor the occlusion test and provide feedback on the performance and success of the occlusion test. Changes in the patient or monitored data can be tracked by looking for changes in the balloon baseline pressure, changes in the amplitude of the pressure waveform, or changes in the pattern of the Pes waveform. Having information from the ventilator will further increase the ability of the system to determine when Pes is changing unexpectedly.
