The present disclosure provides techniques for a ventilator system with a removable airway. A ventilator system may include a removable airway and a base unit. The removable airway may include an air inlet port, a patient inhalation port, an air exhaust port, and a patient exhalation port. The base unit may include two pinch valves. In some cases, the removable airway does not comprise any openings other than the air inlet port, the air exhaust port, the patient inhalation port, and the patient exhalation port. In some cases, the removable airway is configured such that air inside the removable airway does not contact any part of the base unit. In some cases, the removable airway is configured such that air that enters the patient exhalation port is contained within the removable airway along a contiguous path and at no point does the contiguous path contact the base unit.

An oxygen hose system for protecting an oxygen hose from tangling and abrasion includes an oxygen hose that is fluidly coupled to an oxygen source for supplying breathing oxygen to a patient. A sleeve is provided and the sleeve is positionable around the oxygen hose. The sleeve is comprised of a resilient material to inhibit the oxygen hose from being chewed by a domesticated animal. Additionally, the sleeve is comprised of a flexible material thereby facilitating the oxygen hose to be routed in various directions.

A fluid delivery system provides fluid, such as supplement oxygen, to a patient in response to inhalation. The fluid delivery system includes a valve assembly that is triggered by sensing onset of inspiration by measuring a change in temperature of air flow in a nasal or oral cannula, mask or helmet.

In at least one embodiment, a system includes an inhalation source; a plenum in fluid communication with the inhalation source; at least one challenge plethysmography mask in fluid communication with the plenum, for each challenge plethysmography mask including a mask having a cavity to receive at least a nose of a test animal, a delivery conduit in fluid communication with the plenum and the cavity of the mask, at least one exhaust conduit in fluid communication with the cavity of the mask and the plenum, and a pressure sensor attached to the mask to measure pressure within the cavity of the mask; at least one processor in electrical communication with the at least one pressure sensor, the processor configured to process an output signal of the pressure sensor into respiratory data for each test animal during an exposure study; and an exhaust system in fluid communication with the plenum.

A double barreled injector assembly for performing multiple sequential vaccinations includes a pair of barrels, each of which is engaged by a first terminus thereof to a bar and extends from a lower face thereof. A respective agent can be positioned in each barrel. Each barrel has an orifice positioned in a second terminus thereof. A pair of actuators is engaged to an upper face of the bar. Each actuator is operationally engaged to a respective barrel and can be actuated by action of a hand of a user to dispense an associated agent through the orifice of the respective barrel into an animal. The injector assembly allows the user to perform multiple sequential vaccinations with two different vaccines and will be useful in vaccination of herds or flocks of livestock, such as poultry, cattle, and the like.

A spray apparatus adapted to be connected to a fluid supply such as a syringe to spray a predetermined pattern of spray fluid to a target area such as the tissues of an animal or human. The sprayer delivers a predetermined dose of a medicament, vaccine or the like to the nasal or other cavity of an animal or human patient. The sprayer includes a base member and a cap member which is connected to the base member. The base member is connectible to the fluid supply. Spray is discharged from the distal or outward end of the cap member. The base member has a central, longitudinal lumen having a predetermined configuration. Fluid traverses the lumen and is discharged through a central aperture of the cap, which also has a predetermined configuration. The cap central lumen and spray discharge aperture are aligned with the base lumen.

The invention relates to veterinary science. An extrarenal blood purification procedure is performed to remove toxins from the blood. Baseline parameters of urea and creatinine in the blood serum are measured during the blood purification procedure; on the basis of the data obtained, a dialysis intensity index (DII) is determined as the ratio of the patient's total fluid volume to the volume of the fluid purified of toxins and a uremic toxin accumulation index (UTAI) is determined as the rate of accumulation of the quantity of urea or creatinine per unit of time. Moreover, it is deemed necessary to repeat the hemodialysis procedure if the UTAI value for urea is more than 0.5 and/or the UTAI value for creatinine is more than 8, and/or the DII value is less than 0.9.

A system and method are provided to monitor performance of an intraosseous device by using a supporting structure and an attachment mechanism. The attachment mechanism releasably secures the supporting structure proximate an insertion site for the intraosseous device. The supporting structure includes an opening formed therein and sized to receive at least a portion of the intraosseous device. A sensor detects parameters associated with providing fluids and/or medications through the intraosseous device to the bone marrow. The attachment mechanism and the supporting structure cooperate with each other to minimize movement of the intraosseous device relative to the insertion site when the portion of the intraosseous device is disposed in the opening of the supporting structure.

Disclosed herein are systems and methods for providing a portable magnetic field therapy system for treatment of diseases and adverse health conditions, such as cancer.

The invention relates to a radial blood pump (1) for supporting a blood flow (106) in a human or animal heart (205) comprising a first and a second inlet channel (41, 42), a first outlet channel (51, 52), a first electric motor (71) comprising a first stator (77) and a first internal rotor (75), wherein the first electric motor (71) is configured to drive an impeller (2, 2a, 2b) arranged at an intersection of the first with the second inlet channel (41, 42), wherein the impeller (2, 2a, 2b) is connected to the first internal rotor (75) and wherein the impeller (2, 2a, 2b) comprises a merging portion (22) arranged at the intersection, where a merging of a first blood flow (106) coming from the first inlet channel (41) and a second blood flow (107) coming from the second inlet channel (42) takes place, wherein the impeller (2, 2a, 2b) is configured to pump the first and second blood flow (106, 107) from the first and second inlet channel (41, 42) via the merging portion (22) to the first outlet channel (51), a plurality of blades (20) comprised by the impeller (2, 2a, 2b), wherein the blades (20) form blade channels (21) comprised by the merging portion (22), wherein each blade (20) is arranged and configured to pump the first and second blood (106, 107) flow entering through the first and the second inlet channel (41, 42) towards the outlet channel (51), wherein the blood pump (1) is arranged and configured such that the first blood flow (106) and the second blood flow (107) meet at the merging portion (22), such that a pressure difference between the first and second blood flow (106, 107) is reduced before blood from first and second blood flow (106, 107) is pumped to the first outlet channel (51).
