An allergen exposure system includes a mixing chamber, delimited by walls and distinct from the air inlet duct and from the exposure room in which the patients are situated. A mixing between a stream of allergen particles from an allergen injection device and a flow of air devoid of allergens which has passed through a filtration device, occurs through a phenomenon of microturbulence in this mixing chamber which forms a widening with respect to the air inlet duct and makes it possible to obtain a flow of air laden with allergen particles which is injected into the exposure room through at least one diffusion outlet so that it can be inhaled by the patients. This invention is of benefit to medical and pharmaceutical research in the field of allergy study.

A system can include a plurality of infusion pumps and a connectivity adapter in a clinical environment. The connectivity adapter can receive update data, such as a drug library update or an operational software update, and can store the update data within the clinical environment. The connectivity adapter can send the update data to a predetermined number of infusion pumps that have requested the update. At least two subsets of the infusion pumps can receive different blocks of the update data at about the same time. Further, the same or different update data can be provided to the infusion pumps at about the same time.

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.

Systems and methods are presented for providing reduced pressure to and monitoring pressure at a plurality of tissue sites using a plurality of pressure management devices. The pressure management devices are associated with a plurality of sensing conduits that fluidly couple the pressure management devices and the plurality of tissue sites. Other systems, methods, and devices are disclosed.

A nebulizer capable of connecting with a mouthpiece is provided. The nebulizer includes a container, a nebulizing part, a first tube and a second tube. The container is configured to accommodate a liquid. The nebulizing part includes a chamber and a nebulizing element communicating with the container and nebulizing the liquid in the chamber. The first tube connected with the nebulizing part includes a first channel communicating with the chamber and introducing an outside airflow. The second tube is connected with the nebulizing part and the mouthpiece. A second channel of the second tube communicates with the chamber and the mouthpiece. The second tube has an expanding part at a junction of the second channel and the chamber.

A remote control device may be used to wirelessly control functions of one or more dialysis machines, e.g. in a clinic environment and without requiring direct contact with the dialysis machines. Components of the remote control device may include control interfaces, e.g. buttons, for controlling and adjusting functions of a medical device, such as a dialysis machine, including, for example, volume control, blood pump control blood flow rate control and/or adjusting the level in the venous drip chamber, among other control features. Display of the remote control device may include one or more screens that may display information of one or more dialysis machines, patients undergoing dialysis treatment, and/or alarms or alerts of one or more of the dialysis machines. In an implementation, ultrasonic communication is used to wirelessly exchange information and commands between the remote control device and the one or more dialysis machines.

Circadian stimulus illumination control systems and methods are disclosed. Embodiments include a control system providing selection of a preset circadian stimulus profile, including a desired circadian stimulus level for setpoint times, for example, including a color temperature and brightness level for each setpoint time to simulate local natural sunlight conditions or a different selected lighting and/or stimulus condition. The control system wirelessly transmits information for the setpoints of the profile to lighting devices, which incrementally transition the color temperature and dimming of the lighting device between the profile setpoints.

Disclosed are systems and methods for influencing the mood of a person using a synthetic window. The system includes storing one or more excitement scenes and one or more calming scenes, where the excitement scenes when displayed on the display produce an excitatory environment and the calming scenes when displayed on the display produce a calming environment. The system also includes receiving input as to a type of mood of the person, selecting an excitement scene or a calming scene in response to the mood type received, and displaying the selected scene on the display.

A ventilator that utilizes a cam lever to raise a piston within a cylinder is provided. The weight of the piston can push breathable air out of the cylinder to a patient. A motor assembly provides the only electronic component necessary to operate the ventilator. Adjustments to volume, speed, and pressure can be made by adjusting mechanical components of the ventilator.

A system, method, and apparatus for the collection of surgical/wound fluid from a subject patient with the capability of simultaneous fluid removal from a plurality of such wounds and/or wound through the utilization of a single pump device worn by such a patient. Such a system, method, and apparatus allow for such a single pump device to collect surgical/wound fluid within a single site collection component attached to or associated with such a single pump device. Multiple fluid transfer lines may be incorporated with the single pump device leading to such plurality of wounds and/or wound sites for greater versatility and comfort for the subject patient, as well as cleaner removal capabilities than in the standard apparatus systems and method currently undertaken within the industry.
