Implementations of the present disclosure are directed to conserving energy of an injection device that includes an energy source configured to power an electronic component, a priming component configured to generate a trigger, a reactant configured to generate an instantiation signal in response to the trigger, and a sensor configured to detect and process the instantiation signal and generate an activation signal to activate the energy source.

A method for extracorporeal treatment of a body fluid of a patient suffering from sepsis, in an extracorporeal flow line, comprising removing at least one harmful substance from the body fluid of the patient. In a first injection step, a first mixture containing functionalized magnetic particles bound to at least a first binding agent at least directed against a first type of target molecules contained in the body fluid is added to the extracorporeal flow line comprising a sample of the body fluid extracted from a patient and containing at least the first type of target molecules. The first mixture is injected in a therapeutically effective dose necessary to reduce a concentration of the target molecules of at least the first type in the body fluid sample of the patient, followed by a mixing step and a separation step for reduction of the target molecule concentration.

A heat and moisture exchanger device comprising a housing containing a microcurrent-generating filter capable of generating a low level microcurrent. A microcurrent-generating filter can reduce the number of living or active microbes.

An IV set includes an IV component and a duration monitor device coupled to the IV component. The duration monitor device may include an indicator portion configured to change color after a determined amount of time upon activation of the indicator portion, or an RFID tag configured to be detected by an RFID reader. The duration monitor is configured to provide an indication of passage of a useful-life time period for the IV set or the IV component. Methods of operating a duration monitor device are also provided.

An intracorporeal temperature changing intracorporeal fluid delivery device is described that includes an outer shell forming an internal enclosure comprises at least one heat generation layer and a heater activation system. In one embodiment, the invention is a intracorporeal fluid delivery device, such as an intravenous fluid device. As such it is generally configured for delivery of a heated fluid to a user, and is configured to be worn about an appendage of the user such as an arm, leg, or neck or otherwise operatively connected to a user.

A chemical pump assembly useful for negative pressure therapy includes a chemical pump housing having an inner chamber, a reactor located within the inner chamber, an opening provided in the chemical pump housing, a first pull tab which extends from the inner chamber to ambient through the opening, and a removable layer connected to the first pull tab. The reactor is configured to react with a selected gas found in air so as to consume the selected gas when exposed to air in the inner chamber. The removable layer shields the reactor from air in the inner chamber atmosphere until the removable layer is removed.

A wound therapy device and method includes a skin contacting element, a reactor, and a reactor housing element. The skin contacting element is configured for covering an associated tissue site, the reactor for creating a pressure condition at the associated tissue site upon actuation thereof, and the reactor housing element for accommodating the reactor. The skin contacting element has a skin contacting side and an interface side, which is opposite the skin contacting side. The reactor housing element has a lower affixing side and an upper side, which is opposite the lower affixing side.

The invention relates to a fluid pump or rotary cutter having at least one first element (9″″, 10′″) which can be brought from a transport state into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical, microinvasive area. The object of achieving a transition between the transport state and the operating state which is as comfortable as possible and in so doing leaving a freedom in the design of the corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material (24, 25, 26, 27) or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.

A negative pressure assembly includes a drape, a sealing element, a reactor, and a mechanical pump assembly. The drape covers a dressing site on a patient and seals against the skin upon application of a vacuum while maintaining a negative pressure underneath the drape. When applied to the skin, the sealing element cooperates with the drape to define an enclosed volume covered by the drape and surrounded by the sealing element. The reactor is located with respect to the drape and the sealing element to be in fluid communication with the enclosed volume when the drape is covering the dressing site and is configured to react with and consume a selected gas found in air. The mechanical pump assembly is connectable to the enclosed volume and has a pump chamber in fluid communication with the enclosed volume to draw air from the enclosed volume into the pump chamber.
