Provided is a ventilator that includes a breathing system, a mechanical system coupled to breathing system, and a control system coupled to breathing system and mechanical system. The control system includes pressure sensors, processing circuitry, and memory configured to store a look-up table. The processing circuitry receives a set of values for plurality of parameters, identifies a compression value from a plurality of compression values in the look-up table based on the received set of values. The processing circuitry causes the mechanical system to compress a bag valve of the breathing system in accordance with the identified compression value. The compression of the bag valve causes a gaseous inhalant to flow through the breathing system within a time-interval. The processing circuitry determines an actual volume of the gaseous inhalant and iteratively modifies the compression value of the bag valve to match a desired volume of the gaseous inhalant.

A medical system, device, and methods are provided having programming to communicate with a mobile device; the medical device further having programming to authenticate the mobile device; the medical device granting access to one or more functions if the mobile device is authenticated.

Enhanced systems and methods for performing Direct Sodium Removal (DSR) therapy are provided in which an implantable device includes a variable speed motor-driven pump that may be programmed to output different flow rates at different stages of a DSR therapy session, wherein the system monitors operational parameters of the pump and is configured to generate an alarm condition indicative of a fault that may be displayed on a patient's smartphone to permit corrective action, and in which a catheter set implanted with the implantable device enables a DSR solution may be instilled into the patient's peritoneal cavity using a peritoneal catheter that is subsequently used to remove the DSR solution and sodium-rich ultrafiltrate from the peritoneal cavity to the patient's bladder.

A respiration device (1) supports cardio-pulmonary resuscitation (CPR) and a method for operating a respiration device (1) supports cardio-pulmonary resuscitation (CPR). The respiration device (1) has a control and regulation unit (7) in order to actuate an expiratory metering unit (3), and an inspiratory metering unit (2) such that, in a first phase, a current value of pressure is increased relative to a first pre-defined value (16) and such that, in a second phase, the current value of the pressure is reduced relative to the first pre-defined value (16).

A respiratory flow therapy apparatus including a sensor module can measure a flow rate of gases or gases concentration provided to a patient. The sensor module can be located after a blower and/or mixer. The sensor module can include at least an ultrasonic transmitter, a receiver, a temperature sensor, a pressure sensor, a humidity sensor and/or a flow rate sensor. The receivers can be immersed in the gases flow path. The receivers can cancel delays in the transmitters and improve accuracy of measurements of characteristics of the gases flow. The receivers can allow for detection of a fault condition in a blower motor of the apparatus.

In some embodiments, a self-monitoring intravenous catheter system is provided. An alarm controller is provided that receives signals representing a pH value, an oxygen saturation value, and a pressure value in proximity to the distal end of the catheter. By performing a fuzzy logic analysis of the values, the alarm controller is able to detect that the catheter is about to fail or has failed, and can cause alerts to be presented. In some embodiments, an intravenous catheter is provided that has a pH sensor and an oximeter disposed at a distal end of the catheter to obtain the pH value and oxygen saturation values analyzed by the alarm controller. Embodiments of the catheter and self-monitoring intravenous catheter system may be particularly useful in treating neonates, who are sensitive to catheter failure and are not capable of detecting the signs of failure themselves.

The methods, systems and devices provided herein relate to sleep-aid. Some embodiments include a vibration source and/or a sound source. In some embodiments, the vibration source and/or sound source emit vibrations and/or sounds that stimulate a subject's vagus nerve, or another nerve, to induce sleep or relaxation in the subject.

A method includes, in a processor, receiving signals from (i) a first position sensor disposed on a shaft of a catheter, and (ii) a second position sensor disposed on a distal end of a sheath of the catheter. Based on the signals received from the first position sensor and the second position sensor, an event is detected in which an expandable distal-end assembly of the catheter is being withdrawn into the sheath while still at least partially expanded. A responsive action is initiated in response to detecting the event.

The present disclosure relates to a test device to be inserted into the syringe receptacle of a pump, for example for a blood treatment apparatus, for testing at least one function of the pump and/or of the blood treatment apparatus. The test device includes a holding device for releasably holding the test device on the housing of the blood treatment apparatus. In addition, the test device includes at least one movable actuator and at least one electric motor arranged to directly or indirectly move said movable actuator or a section thereof.

A method for managing delivery of medication to a patient including medication dosage control and medication flow rate control for the patient. The method comprises controlling flow rate of the medication to be delivered to the patient through a needle that is subcutaneously inserted into the patient including: monitoring glucose levels in the patient using a continuous glucose monitoring device; converting the glucose levels from the continuous glucose monitoring device into instructions by control algorithms within a microcontroller unit; commanding a pumping unit to deliver the medication through the needle at a flow rate based on the converted instructions; and delivering the medication through the needle into the patient at the flow rate; and adjusting the flow rate continually to reduce a difference between actual flow rate measured off of the pumping unit and a converted flow rate from the continuous glucose monitoring device.
