A splitter module is configured to connect a single medical ventilator to multiple intubated patients. The splitter module is configured to independently control at least one ventilation parameter for each of the patients, such that modifying a ventilation parameter of one of the patients does not significantly affect the ventilation parameters of the other patients.

In general, one aspect disclosed features a scalable ventilator system, comprising: a plurality of ventilator modules; a controller to control operation of the plurality of ventilator modules; and a station module comprising a plurality of receptacles, wherein each receptacle is configured to accept one of the plurality of ventilator modules; wherein each ventilator module comprises a plurality of solenoid valves and an input hose and an output hose, wherein each ventilator is controlled individually to provide individualized regimens based on needs of a patient corresponding to a respective ventilator.

A ventilator uses teeth of gear to operate up to eight or more bellows. A common drive shaft can be used to operate a stack of multiple such gears, which collectively operate up to 40 or more bellows. Valves can be used to control flow from different ones of the bellows to individual recipients.

A system and method for updating patient devices is disclosed. The patient devices (720, 730, 740) may include respiratory therapy devices (4000) that operate in accordance with instruction sets (726), such as software or firmware. A server (710) may maintain a database of configuration data (718) indicating the versions of the software and firmware that is currently installed on the patient devices (720, 730, 740). The server (710) may also transmit updated instructions (716) from over a network (4282), including a wireless network. Particular patient devices (720, 730, 740) may be selected for updating based on the configuration data (718). Upon performing an update a patient device (720, 730, 740) may transmit configuration data (728) to the server (710).

A method for stabilizing dialysate consumption flow in a central distribution loop for a plurality of dialysis machines comprises: coordinating each dialysate dispensing cycle of active ones of the dialysis machines; calculating dialysate or concentrates consumption based on amount required in each dialysate dispensing cycle of the active dialysis machines; and preparing the dialysate based on the calculated dialysate or concentrates consumption required by the active dialysis machines. Also a corresponding apparatus and a corresponding central dialysate preparation and distribution system are disclosed, wherein the apparatus at least comprises: a coordinating module configured to coordinate each dialysate dispensing cycle of active ones of the dialysis machines; a calculating module configured to calculate dialysate or concentrates consumption based on amount required in each dialysate dispensing cycle of the active dialysis machines; and a mixing control module, for preparing the dialysate based on the calculated dialysate or concentrates consumption.

A method, apparatus, computer program, programmable device and system are all disclosed for the detection of the actuation of an inhaler and breath of a user from audio data. The method comprises identifying, based on a high frequency band of the audio data, actuation of the inhaler. The method additionally comprises identifying, based on a low frequency band of the audio data and based on the identified actuation of the inhaler, an interval of the audio data comprising the breath of the user.

A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.

The invention relates to a hose system with an inspiratory hose portion which is configured for connection to a respective inspiration channel of a ventilation apparatus and which is configured to convey an inspiratory respiratory gas flow from the ventilation apparatus to a patient interface. The inspiratory hose portion has a hose adapter which is configured for connection to the inspiration channel of the ventilation apparatus. The hose adapter has a hose branch point from which at least two inspiration branches branch off, wherein each inspiration branch has at least one attachment piece for connection to a patient interface.

A system for providing mechanical ventilation to a plurality of patients using a single ventilator is provided. The system includes a first branched adapter may be coupled to a ventilator, the first branched adapter having a plurality of branches and configured to divide a ventilator gas stream into a plurality of gas streams for delivery to a respective plurality of patients. The system includes a pressure regulator in fluid communication with one branch of the first branched adapter and with one patient, the pressure regulator being configured to reduce the pressure of the gas stream reaching the patient such that it is less pressurized than the ventilator gas stream. The system includes a second branched adapter may be coupled to a ventilator, the second branched adapter having a plurality of branches and configured to unite expired gas streams from the plurality of patients into a single expiratory gas stream.
