A support device to support a catheter assembly may include a platform, which may include an upper surface and a bottom surface. The support device may include an extension element coupled to the upper surface of the platform. The extension element may include a distal end, which may include a first connector configured to couple to the catheter assembly, and a proximal end, which may include a second connector. The extension element may include a valve that may be movable between a first position and a second position. In response to the valve being moved to the first position, a fluid pathway extending through the cannula and the extension element may be open and straight. In response to the valve being moved to the second position, the fluid pathway may be closed. The support device may include a cannula, which may be swaged within the extension element.

A dilution spacer for a metered-dose inhaler comprises an enclosure defining a dilution chamber. An ambient air inlet and an outlet are in fluid communication with the dilution chamber. The ambient air inlet is positioned opposite the outlet whereby suction through the outlet from outside the enclosure draws ambient air into the enclosure through the ambient air inlet to generate an airflow path from the ambient air inlet through the dilution chamber and out of the outlet. The dilution spacer may include an actuator inlet configured to securely releasably interengage a metered-dose inhaler actuator mouthpiece, or may include a receptacle having an actuator nozzle and configured to receive a metered-dose inhaler canister, A metered-dose inhaler plume entering the dilution chamber intersects the airflow path thereto and airflow along the airflow path entrains and redirects at least a portion of the metered-dose inhaler plume toward the outlet.

The present invention relates to an extensible drug injection device capable of injecting a drug from a location away from a patient, and an operation method therefor. Disclosed is a drug injection device comprising: a first sub-line of which one end joins with a main line, connected from a first drug storage part for storing a first drug to be injected into a patient to the body of the patient such that the first drug flows therein, and of which the other end is extended to the other side; a second drug injection part which is connected to the first sub-line and which injects a second drug that is different from the first drug; and a second drug pumping part which is connected to the first sub-line, and which pushes, to the main line, the second drug having been injected by the second drug injection part into the first sub-line.

An ambulatory infusion device including a pump drive unit, a valve drive unit and a control unit. The pump drive unit includes a pump actuator and a pump driver coupled to a piston of a metering pump unit. The valve drive unit includes a valve actuator and a valve driver coupled to a valve unit for transmitting a valve switching force or torque. The control unit controls a repeated execution of: (a) placing the valve unit in a filling state; (b) displacing the piston in a retraction direction; (c) displacing the piston in an advancing direction by a backlash compensation distance; (d) switching the valve unit from the filling state into a draining state; and (e) further displacing the piston in the advancing direction in a number of incremental steps over an extended time period.

Bubble traps for use in medical fluid lines and medical fluid bubble trap systems are disclosed herein. In some embodiments, the bubble trap is configured to trap gas (e.g., air) that flows into the bubble trap from a fluid line. In some embodiments, the bubble trap includes an inlet and an outlet and a chamber between the inlet and the outlet. For example, in some embodiments, the bubble trap is configured to inhibit gas from flowing into the outlet once gas flows into the chamber from the inlet. In some embodiments, the bubble trap is in fluid communication with a source container, a destination container, and/or a patient.

In some embodiments, an external bladder management system that is configured to reside within a urine collection receptacle (e.g., a toilet) includes a body that houses a fluid testing chamber. The fluid testing chamber is fluidically coupled to a fluid inlet and a fluid outlet. The system further includes a fluid capturing funnel fluidically coupled to and extending from the body and configured to couple the body to the urine collection receptacle. The system further includes an optical sensor disposed within the body and including (1) an emitter configured to convey light across the fluid testing chamber, and (2) an optical detector capable of measuring an intensity of the light as the light exits the fluid testing chamber. The fluid inlet, fluid testing chamber, and fluid outlet are collectively configured to encourage a laminar flow profile of the fluid as it flows through the fluid testing chamber.

A drainage liquid sampling system is disclosed and includes a connector couplable with a drainage tube of a drainage system, the connector defining an inlet port, an outlet port, and a sample port, where the inlet port, the outlet port, and the sample port are in fluid communication with each other, and a sample container couplable with the sample port. A valve within the connector selectively allows and prevents flow of drainage liquid into the sample container. A cap couplable to the sample container also includes a valve. A system for draining liquid from a patient includes the drainage liquid sampling system.
