A cartridge-based biofluid monitoring system and method of using same are disclosed. The biofluid monitoring system uses a biofluid cartridge configured to be removably inserted into a biofluid cartridge housing. The biofluid cartridge housing can be rotated so that multiple types of analysis can be conducted on one biofluid collection. The biofluid monitoring system may be used at a user's home or at other locations that allow for real-time biofluid monitoring to occur. The biofluid monitoring system allows for point-of-care detection and monitoring of a multitude of clinically relevant biological markers of current or changing health and disease states, by analyzing the user's biofluid.

A medical instrument includes an instrument shaft with exit holes near a distal end of the shaft, a tool coupled to the distal end of the shaft, and a backend. The backend may include a mechanism that manipulates a drive element that extends through the shaft and couples to the tool, a fluid inlet, and a fluid channel assembly providing fluid communication between the fluid inlet and the proximal end of the shaft. Cleaning fluid is directed into the fluid inlet, through the fluid channel assembly, and into the shaft. A chassis or other structural piece of the backend may form part of the fluid channel assembly.

A fluid collection system may include a fluid collection assembly configured to receive urine from a user, a container configured to sore the urine collected from the fluid collection assembly, a collection tube disposed between the fluid collection assembly and the container, and a bi-directional pump. The fluid collection system operates in a first configuration to draw urine from the fluid collection assembly into the container and a second configuration to drain the urine and clean the fluid collection system.

A disposable cleaning unit is described herein including an inner receptacle and an outer receptacle.

An arrangement, and associated method, for cleaning and disinfecting an endoscope having an internal channel accessible via an opening. The arrangement includes: a support structure; at least one tray including at least one fixture arranged to maintain the endoscope in the desired position within the tray; a rack arranged to support the tray; a control unit arranged to control and operate the arrangement; a user interface connected to the control unit and arranged to make it possible for an operator to indicate the type of endoscope arranged in the tray; an optical device connected to the control unit and configured to confirm the type of endoscope arranged in the tray; a robotic device operated by the control unit and arranged to clean the at least one channel in the endoscope arranged in the tray; and a disinfector device arranged to enclose the tray and disinfect the endoscope.

A variable-flow-rate anti-clogging emitter includes an upper casing and a lower casing, where the upper casing and the lower casing are fixedly connected with each other; the upper casing has a flat top surface provided with a water outlet and a bottom surface provided with a truncated conical slot in communication with the water outlet; the lower casing includes a flow channel portion and a discharging portion, which are recessed in an upper surface of the lower casing; the flow channel portion has one end provided with multiple parallel feeding channels and an other end communicated with the discharging portion; one end of a lower surface of the lower casing is provided with an L-shaped platform; water inlets of the multiple feeding channels are arranged on a side wall of the L-shaped platform; and an elastomer flow channel is fixedly provided between the upper casing and the lower casing.
