A negative-pressure massaging device capable of volatilizing essential oil is provided. The negative-pressure massaging device includes a negative-pressure cup and an essential oil volatilizing structure. The essential oil volatilizing structure is disposed in the negative-pressure cup and includes a heat conducting unit, a heating unit, and an essential oil unit. The heating unit is disposed on and contacts the heat conducting unit to heat the heat conducting unit. The essential oil unit is disposed on and contacts the heat conducting unit to be heated. The essential oil unit is heated by the heat conducting unit to volatilize essential oil into the negative-pressure cup. Accordingly, an aromatherapy may be provided when a negative-pressure massaging treatment is performed.

Devices and methods for providing inhalable vapor are disclosed. A device may include a body with a first distal and proximal section; a first connector that releasably couples with a cartridge that provides a volatizable material; and a sleeve integral with or releasably coupled to the body, the sleeve defining a first aperture dimensioned to accommodate at least the width of the cartridge.

A medical device (10) includes a device housing (12). An in-line thermal mass flow sensor (26) includes a heater (28) and at least one temperature sensor (30). The in-line thermal mass flow sensor is vertically mounted on or in the device housing. The in-line thermal mass flow sensor is configured to measure a flow rate of the fluid through the medical device. At least one electronic processor (18) is programmed to: read the flow rate of the fluid measured by the in-line thermal mass flow sensor, and detect at least one bubble in the fluid based on the measured flow rate.

A retaining table for use with a fluid processing system includes a plate having a generally flat top surface with opposed first and second ends and opposed first and second lateral edges for supporting a disposable container, a first retaining structure connected to the plate along the first end, and a second retaining structure connected to the plate along the second end.

A thermal disinfection system and a method to perform a thermal disinfection procedure of fluid lines of a medical apparatus are disclosed herein. In an example, the thermal disinfection procedure comprises at least the steps of receiving a temperature signal from a temperature sensor, determining a measured temperature value of a fluid within a hydraulic circuit, receiving a pressure signal from a pressure sensor, determining a measured local atmospheric pressure value, and driving a heating unit to heat the fluid based on the measured temperature value and the measured local atmospheric pressure value.

The present invention generally relates to hemodialysis and similar dialysis systems, including a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. One aspect of the invention is generally directed to new fluid circuits for fluid flow. In one set of embodiments, a hemodialysis system may include a blood flow path and a dialysate flow path, where the dialysate flow path includes one or more of a balancing circuit, a mixing circuit, and/or a directing circuit. Preparation of dialysate by the preparation circuit, in some instances, may be decoupled from patient dialysis. In some cases, the circuits are defined, at least partially, within one or more cassettes, optionally interconnected with conduits, pumps, or the like. In one embodiment, the fluid circuit and/or the various fluid flow paths may be at least partially isolated, spatially and/or thermally, from electrical components of the hemodialysis system. In some cases, a gas supply may be provided in fluid communication with the dialysate flow path and/or the dialyzer that, when activated, is able to urge dialysate to pass through the dialyzer and urge blood in the blood flow path back to the patient. Such a system may be useful, for example, in certain emergency situations (e.g., a power failure) where it is desirable to return as much blood to the patient as possible. The hemodialysis system may also include, in another aspect of the invention, one or more fluid handling devices, such as pumps, valves, mixers, or the like, which can be actuated using a control fluid, such as air. In some cases, the control fluid may be delivered to the fluid handling devices using an external pump or other device, which may be detachable in certain instances. In one embodiment, one or more of the fluid handling devices may be generally rigid (e.g., having a spheroid shape), optionally with a diaphragm contained within the device, dividing it into first and second compartments.

The present application relates to an implantable blood pump for assisting a heart function. The blood pump comprises a heat source and a wall that delimits a flow cannel. In addition, the blood pump comprises a heat distributor for distributing heat generated by the heat source to a surface of the wall. In order to transfer heat from the heat source to the blood conveyed in the flow channel, the heat distributor is thermally conductively connected to the heat source and thermally conductively connected to the opposite face of the wall from the flow channel.

A blood pump for supporting the heart may be provided that includes: a rotor with delivery elements; a rotor drive; a pressure sensor; and a regulating device that regulates a pressure or a hemodynamic parameter by means of control of the rotor drive. The pressure and/or the hemodynamic parameter may be determined by means of one or a plurality of hemodynamic sensors and/or from operating parameters of the pump. The regulating device may be suitable for regulating a hemodynamic parameter successively, such as periodically, to different target values. Using such regulation, the blood pump may be operated in an optimized manner, and operation of the blood pump may be varied in a targeted and patient-protective manner in order to attain certain goals.

This disclosure relates to a system and method to improve the uniformity of the heat transfer coefficient of containers filled with biological materials during the freezing and thawing process, in particular a system that is easily transported and incremented to other conventional freeze-thaw methods and equipment. The system includes a portable air blast system configured to receive a container filled with biological materials and to be placed in a cooling or heating chamber, for homogeneous and reproducible freezing and thawing of biological materials. This disclosure also relates to a method of freezing and thawing biological solution inside a container by using the portable air blast system according to any of the previous claims 1-12, comprising: obtaining a container filled with biological solution; placing the container into the vent enclosure and on the stand of the air blast system; placing the air blast system with the container into a heating or cooling chamber; activating the air blast system by activating the fan in the air blast system.

The present disclosure relates to a medicament delivery devicecomprising at least one microneedle for delivering a medicament to a patient, and a system configured to enhance the penetration of the medicament into skin of the patient.
