A method for removing excess fluid from a patient with hemodilution is provided. The method includes: deploying a urinary tract catheter into the patient such that flow of urine from the ureter and/or kidney is transported within a drainage lumen of the catheter; applying negative pressure to the ureter and/or kidney through the drainage lumen of the catheter to extract urine from the patient; periodically measuring a hematocrit value of the patient; and if the measured hematocrit value is greater than a predetermined threshold value, ceasing the application of the negative pressure to the ureter and/or kidney. A system for removing excess fluid from a patient with hemodilution including a ureteral catheter and a pump is also provided.

A pump for inducing negative pressure in the ureter and/or kidney is provided. The pump is configured to be in communication with at least one lumen of at least one ureteral catheter and to draw fluid from the ureter and/or kidney into the at least one lumen of the at least one ureteral catheter for removal of the fluid from the ureter and/or kidney. The pump is configured to induce negative pressure ranging from about 0.1 mmHg to about 50 mmHg gauge pressure proximate to the pump inlet, and the pump is configured to have an accuracy of about 10 mmHg or less proximate to the pump inlet.

Ureteral catheters and assemblies are provided including: a drainage lumen including a proximal portion configured to be positioned in at least a portion of a patient's urethra and a distal portion configured to be positioned in a patient's ureter and/or kidney, the distal portion including a coiled retention portion including at least a first coil having a first diameter and a second coil having a second diameter, the first diameter being less than the second diameter; or wherein the retention portion extends radially outwardly from a portion of the distal end of the drainage lumen portion, the retention portion including a proximal end having a first diameter, a distal end having a second diameter, and a wall and/or surface extending therebetween, the retention portion having a second diameter is greater than the first diameter when deployed; or wherein the retention portion includes a plurality of drainage tubes.

A urinary catheter assembly (10) Includes a catheter tube (14), a connector (16), and a urine collection bag. The assembly further includes a package with a body receiving the catheter tube (18) and the urine collection bag (18) is in its compact configuration. The bag (18) may be variously configured, such as having a non-woven fabric backing portion and/or an outer adhesive or containing a superabsorbent polymer additive.

Devices, systems, and methods for delivering fluid therapy to a patient are disclosed herein. An exemplary method can comprise obtaining a urine output rate from a patient; causing a diuretic to be provided to the patient at a dosage rate, wherein the dosage rate is increased over a period of time such that the urine output rate increases to be above a predetermined threshold within the period of time; and causing a hydration fluid to be provided to the patient at a hydration rate. The hydration rate can be set based on the urine output rate to drive net fluid loss from the patient.

A fluid collection system for collecting fluid, such as urine through a series of valves and bags that isolate urine from the input to reduce risk of infection includes an input tube connected removably to a fluid supply tube, first and second valves separate from one another and each having flow-on and flow-off states and each fluidically connected to the input tube, respectively, to receive the input fluid and to output the input fluid when in the flow-on state, and at least one hollow collection container defining a water-tight interior and comprising a removable connector configured to removably connect to one of the first and second valves and, responsive to connection thereto, configured to receive the input fluid. The bags also contain a hydrogel to absorb the fluid. Input fluid pressure can be controlled and calibrated to maintain backpressure on the bladder.

Systems, devices and methods for draining and analyzing bodily fluids and assessing health are described generally comprising a pumping mechanism which is fluidly connectable at a first end to a portion of a drainage line and a venting mechanism having a one-way valve and which is connectable at a first end into fluid communication with a drainage catheter and the drainage line. The pumping mechanism may be configured to create a negative pressure within the drainage line when the pumping mechanism is in communication with the drainage line, and the one-way valve may be configured to open to an environment when the venting mechanism is connected at the first end and when the drainage line is at a pressure less than an environmental pressure such that an airlock is prevented from forming within the drainage line.

A system and method for automatically removing by suction urine voided by a female. The system includes an external catheter. The external catheter includes a suction tube having a portion enclosed in a hydrophilic sponge cover. The suction tube is arranged to be coupled to suction of a desired value. The cover is arranged to be disposed externally at the female's urethra opening to receive urine voided by the female, whereupon the suction draws the urine through the cover into the suction tube. The external catheter is arranged to be connected to a receptacle for collecting the urine received by the external catheter. Various embodiments of the suction tube and the cover are disclosed.

A sterile closed intermittent urinary catheter system which is an easier to use by virtue of ergonomic shaping to facilitate advancement and retrieval of the catheter from the collection bag. The bag may have a closed internal hole adjacent an indent in one edge that creates a narrow channel through which the catheter passes. The narrow channel is located near to and in alignment with an outlet assembly so that the catheter extends from the narrow channel directly to the outlet. A user may easily grasp the catheter from outside the bag at the narrow channel and urge the catheter forward or backward to alternately extend and retract it through the outlet. A flexible pusher sleeve with gripper features may be added around the narrow channel to further facilitate catheter advancement.

A system for automatically removing by suction urine voided by a female. The system includes an external catheter, a canister and a suction regulator. The external catheter is applied at the urethra opening to receive urine voided by the female. The canister collects the urine and is coupled to a source of suction having a first value. The suction regulator is interposed between the external catheter and the canister to regulate the amount of suction to a regulated value which is applied the external catheter, whereupon urine from the external catheter is carried through the suction regulator and into the canister. The system may also include an adapter or an adapter/splitter for connection between the source of suction and the canister.
