Disclosed is a massage device according to one embodiment of the present disclosure. The massage device comprises: a body structure for forming an area to accommodate at least one portion of the body of a user and defining the outer shape of the massage device; a massage module for supplying a massage function to the at least one portion of the body of the user accommodated in the area in the body structure; an input unit for receiving an input of an arbitrary form from the user of the massage device; a display for displaying massage mode screen information which can be selected by the user of the massage device; and a control unit for controlling one more operations of the massage device on the basis of at least a part of the input of an arbitrary form received by the input unit. The massage mode screen information may include: an automatic mode graphic object linked to a function of performing an automatic mode consisting of a predetermined massage pattern and massage time; a manual mode graphic object linked to a function of performing a manual mode to allow a user of the massage device to configure a massage pattern and massage time; and a massage option mode graphic object linked to a function enabling selection of a massage option mode consisting of an additional function that provides convenience to a user of the massage device in addition to a massage operation that applies pressure to at least a part of the body of the user of the massage device.

Methods and apparatus provide communications among respiratory therapy device (“TD”), server and intermediary (e.g., a control device (“CTLD”) for the therapy device) to improve security. More secure communication channel(s) may be established using shared secrets derived with different channels. The communications may include transmitting therapy data from TD to server for authentication. The CTLD may receive the data and a nonce from a server. The CTLD receives from the TD a signing key dependent on the nonce and a secret shared by TD and server. The CTLD generates an authorisation code with received therapy data and the key for authentication of the data by the server upon its receipt of the code and data. The server computes (1) a key from the nonce and the secret known to TD, and (2) another authorisation code from received therapy data and the key. Data authentication may involve comparing received and computed codes.

Disclosed herein are embodiments of methods of using stabilizers for use in delivering a replacement heart valve. The stabilizers can receive a portion of a delivery system, such as a handle, to prevent unwanted motion of the delivery system. The stabilizer can include a linear actuator for adjusting a position of the delivery system once held within the stabilizer.

Apparatuses, systems and methods for the wireless communication of medical devices in a subcutaneous fluid delivery system are disclosed. A system for subcutaneous fluid delivery includes a primary patch pump adapted to attach a first infusion cannula to a user and to perform a plurality of primary patch pump functions, and a secondary patch pump adapted to attach a second infusion cannula to a user. The secondary patch pump is further adapted to perform a plurality of secondary patch pump functions substantially similar to the plurality of primary patch pump functions if an error condition associated with the primary patch pump is determined.

Embodiments provide an oxygen supply device having multiple operational states including a first state and a second state. In the first state, the oxygen supply device is controllable to a local control instruction such that the oxygen supply device can be operated by a user physically located within a proximity of the oxygen supply device. In the second state, the oxygen supply device is only controllable to a remote-control instruction such that the oxygen supply device can be operated by a user remote to the oxygen supply device. For example, the user can be located in an office remote to a location of the oxygen supply device, which, for example, may be placed at a patient's home. In the second state, the user is enabled to control the oxygen supply device from a device associated with the user in the remote location.

A system includes a converter configured to electrically couple to a power source and to a heating element of a vaporizer atomizer. The converter can be further configured to receive a first voltage from the power source and provide a second voltage to the heating element. The converter can be a direct-current to direct-current converter. A power monitor configured to electrically couple to the heating element, measure a current through the heating element, measure a voltage over the heating element, calculate a power and/or resistance, and output a control signal to the converter. The converter can be configured to be controlled by the control signal to vary the second voltage to maintain a target power or a target temperature over the heating element. Related apparatus, systems, techniques and articles are also described.

Ambulatory infusion pumps, pump assemblies, and disposable assemblies, including cartridges, baseplates, cannulas, inserters, and related components therefor, as well as component combinations and related methods.

An example device comprises: a cradle to support a resuscitator bag; a paddle arm comprising: a paddle surface disposed opposite the cradle; and a pair of arms extending from the paddle surface; a housing comprising: top, bottom, front and rear sides, and an opening at the front side, towards the top side; the paddle surface extending through the opening; the pair of arms, of the paddle arm, rotatably attached to the housing at an end opposite the paddle surface towards the rear side; a nut assembly rotatably attached to the pair of arms therebetween; a screw threaded through the nut assembly; and a motor rotatably attached to the housing towards the bottom side of the housing; the motor configured to: drive the screw relative to the nut assembly to move the paddle arm towards and away from the cradle, to compress and release the resuscitator bag when located therebetween.

A device for communicating a driving ability level of a user, the device comprising at least a processor, a memory, and a wireless transceiver. The device is configured to: receive a communication from a medical device, wherein the communication comprises information relating to a condition of the medical device; and send a communication to a vehicle. The information relating to a condition of the medical device is processed in order to determine a driving ability level of the user by the assignment of a category selected from a group comprising a first category and a second category.

An apparatus includes a housing including a power source; a reservoir including an inlet, an outlet, and configured to contain vaporizable material and couple to the housing; and a PTCR heating element configured to electrically couple to the power source and heat the vaporizable material to form an aerosol. The PTCR heating element includes an electrical resistivity that varies based on temperature. The electrical resistivity includes an electrical resistivity transition zone including an increase in electrical resistivity over a temperature range such that, when the PTCR heating element is heated to a first temperature within the transition zone, current flow from the power source is reduced to a level that limits further temperature increases of the PTCR heating element. Related apparatus, systems, techniques, and articles are also described.
