Implementations of the present disclosure are directed to conserving energy of an injection device by using a sensor attached to the housing, the sensor configured to detect a signal associated with an amount of medicament within the injection device and to generate a sensor signal based on the signal, a control component coupled to the sensor, the control component configured to harvest energy to process the sensor signal and to generate injection device data, and an antenna coupled to the control component and configured to transmit a radio frequency signal based on the injection device data.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.

The present invention discloses a novel Automatic CPAP humidifier water chamber refilling and sanitizing system wherein contrary to the traditional approach of standard water chambers, which dry out and run out of water relatively quickly, the claimed assembly provides a constant and on-demand supply of fresh, clean and sanitized water to the CPAP water chamber; and keeps the CPAP water chamber constantly full and prevents the user from feeling discomfort associated with a dry water chamber. The proposed assembly can hold around 3 Liters of water and can supply the CPAP water chamber for many days depending on the CPAP user humidifier settings, for an estimated 7 to 10 days.

In an example, a ventilator includes a first container and a second container in fluidic communication with each other via a liquid. The second container includes a second container space surrounded by the second container and a second liquid surface. A hydrostatic pressure in the second container space results from a pressure differential defined by a difference between the first liquid surface elevation in the first container and the second liquid surface elevation. The second container space increases in size with an increase in the breathing gas supplied from a gas supply line to the second container space. An inhalation line is configured to open to permit a flow of the breathing gas from an inhalation inlet in the second container space to an inhalation outlet outside of the liquid and outside of the second container and coupled to a patient, causing the second container space to decrease in size.

Methods and breast pump devices for simultaneous pumping and feeding breastmilk in the nursing position and quantification of breastmilk consumption are provided. A breast pump device includes a nipple shield for receiving a nipple, a housing having a throughput aperture and a fluid path, the fluid path extending from the nipple shield to the throughput aperture, and a negative pressure source. In some embodiments, the housing further includes a gate to control the quantity of breastmilk displaced to a baby. In some embodiments, the gate operates to respond to the amount of breastmilk displaced to the baby, and thereby allows for quantification. In some embodiments, the quantity of breastmilk displaced is also recorded.

A tub is configured to contain a supply of water and be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain a supply of water and a tub lid connected to the tub base. The tub lid includes an inlet configured to receive a flow of breathable gas to be humidified and an outlet for the humidified flow of breathable gas. The tub further includes a water level indicator configured to indicate a level of the supply of water in the tub base. The water level indicator includes an inclined portion configured to direct the flow of breathable gas from the inlet away from the outlet. The water level indicator may be visible through the inlet.

A respiratory pressure therapy (RPT) device for pressurising breathable air to treat a respiratory disorder in a patient includes a pressure generator configured to pressurise breathable air, an RPT device inlet configured to receive breathable air from externally of the RPT device to be pressurised by the pressure generator, an RPT device outlet configured to be connected to an air circuit to direct breathable air pressurised by the pressure generator to the patient, a dock having a dock outlet and a dock inlet, and an external housing to enclose the pressure generator. The external housing forms an opening sized to alternatively receive an end cap or a water reservoir.
