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 vaporizer system including a portable unit and a tabletop unit is provided. The system can be used in a first mode and in a second mode to vaporize a substance provided to the system by a user. In the first mode, an individual user may inhale vapors generated by the system through a mouthpiece coupled to the portable unit. In a second mode, one user or multiple simultaneous users can inhale the vapors generated by the system via outlets coupled to an aeration chamber of the tabletop unit. The tabletop unit may further include vials that house aromatic substances that can flavor the vapors generated by the system. In some embodiments, the vials may include adjustable apertures that allow the user to change the amount of aromatics provided to the aeration chamber.

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.

A central monitoring system using artificial ventilators, comprises: a plurality of artificial ventilators positioned inside a hospital room in a ward and connected to the respiratory tracts of a plurality of patients recovering inside the hospital room, so as to supply oxygen to the plurality of patients; an image-capturing unit positioned inside the hospital room so as to capture the plurality of patients in real time; a communication unit for receiving a plurality of pieces of patient condition information transmitted from the plurality of artificial ventilators and patient-capturing information transmitted from the image-capturing unit; and a communication connection unit for connecting the plurality of artificial ventilators and the communication unit, and transmitting, to the communication unit, the plurality of pieces of patient condition information transmitted from the plurality of artificial ventilators.

A social virtual dialysis clinic is provided that simulates social community aspects of a clinic group environment for patients undergoing a medical treatment away from a clinic. The described social virtual dialysis clinic system provides for integrated display devices for medical treatment information functionality, such as for dialysis treatment, with social interaction capabilities among multiple remotely-located patients while the patients are undergoing medical treatments at home or while traveling. Scheduling of the patients as participants in the social virtual dialysis clinic may be performed by a remote computer that receives transmitted information from each of the medical treatment machines performing medical treatments, respectively, on the patients.

A system and method for updating patient devices is disclosed. The patient devices may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server may maintain a database of configuration data indicating the versions of the software and firmware that is currently installed on the patient devices. The server may also transmit updated instructions from over a network, including a wireless network. Particular patient devices may be selected for updating based on the configuration data. Upon performing an update a patient device may transmit configuration data to the server.

A mask system includes a cushion for a mask that seals at its upper extent in a region of the nose that is generally above the tip of the nose or pronasale, and extends across a portion of the cartilaginous framework, alar or flares of the patient's nose, e.g., not extending over or across the nasal bone of the patient's nose.

A centrally controlled multi-patient dialysis treatment system (1) as disclosed herein comprises: a dialysate preparation unit (2) configured to prepare a dialysate based on a prescription and control dialysate delivery for dialysis treatments in progress; one or more dialysate modules (3) configured to deliver the dialysate to a dialyzer (4) and control an ultrafiltration process; and one or more patient modules (5) configured to control an extracorporeal blood flow through the dialyzer (4) for the dialysis treatment, wherein the dialysate preparation unit (2), the dialysate modules (3) and the patient modules (5) are configured to be adapted to be assembled into an integrated dialysis treatment system suitable for one or more patients (6). Also an use of the centrally controlled multi-patient dialysis treatment system (1) for one or more patients' dialysis treatments is disclosed herein. For the centrally controlled multi-patient dialysis treatment system, in contrast to the conventional in-center dialysis infrastructures, in addition to cost saving, it is highly space efficient. Moreover, the centrally controlled multi-patient dialysis treatment system is robust and easy to setup.

A mask system includes a cushion for a mask that seals at its upper extent in a region of the nose that is generally above the tip of the nose or pronasale, and extends across a portion of the cartilaginous framework, alar or flares of the patient's nose, e.g., not extending over or across the nasal bone of the patient's nose.

A mobile dialysis fluid generation system includes a cargo unit configured to be transported by a vehicle; a cleanroom located inside the cargo unit; water purification equipment; at least one dialysis fluid preparation unit located inside the cleanroom; and at least one area provided outside the cleanroom but inside the cargo unit for storing at least one of a raw material or containers filled with dialysis fluid. The at least one dialysis fluid preparation unit includes at least one concentrate, a mixing device configured to receive purified water from the water purification equipment and to mix the purified water with the at least one concentrate to form dialysis fluid, and a tubing set for transfer of the dialysis fluid from the mixing device to a container positioned and arranged to receive the dialysis fluid.
