Various arrangements of fluidics systems are disclosed. In one arrangement, an aspiration circuit for a fluidics system is disclosed that selectively controls aspiration. The aspiration circuit comprises an aspiration line operatively connected to a surgical instrument, an aspiration exhaust line operatively connected to a waste receptacle; an aspiration vent line connected at a first end to the aspiration line; and a selectively variable vent valve operatively connected to the aspiration vent line. The variable vent valve may be selectively moved to vary aspiration pressure within the aspiration line. Other fluidics systems are disclosed that include a selectively positionable irrigation valve that may also be incorporated into a fluidics system that includes a variable vent valve.

A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.

There is disclosed in one example an ear irrigation system, including: a control unit including a fluid reservoir; a disposable earpiece constructed to interface with a human subject's ear canal; an extension unit configured to receive the disposable earpiece and to impart fluid to an ingress port of the disposable earpiece; and an umbilical to fluidly couple the fluid reservoir to the extension unit; wherein the control unit is programmed to, responsive to an input from an operator, pump fluid from the fluid reservoir to the extension unit; and wherein the disposable earpiece includes a plurality of vortical fluid guides to guide fluid from an ingress port to an egress port, and to impart to the fluid at the egress port a vortical motion to delaminate a cerumen impaction from the human user's ear canal.

A therapeutic fluid dispenser holder for holding and orienting a bottle for administering fluids to an animal. The therapeutic fluid dispenser holder comprises a sleeve and a hanging line. The sleeve comprises a lower portion having a lower diameter and an upper portion having an upper diameter. The sleeve comprises a sleeve aperture with an outer wall and between an open upper end and an open lower end. The hanging line attaches to a portion of the sleeve and is configured to suspend the therapeutic fluid dispenser holder on an overhead fastener. The outer wall of the sleeve comprises a vertical slot extending from the upper diameter to the lower diameter.

Described is a phacoemulsification device for eye surgery that generally comprises an ultrasonically vibrating aspiration needle that withdraws ocular material from inside of the eye. The ocular material withdrawn from the eye is equally replaced with irrigation fluid provided through irrigation ports in an irrigation sleeve surrounding the aspiration needle. In the event the aspiration needle stops withdrawing ocular material, such as if it becomes occluded with a chunk of ocular material, irrigation fluid is directed to the outside of the eye via at least one irrigation aperture to keep the eye cool where the needle is ultrasonically vibrating.

Ternary phased medical procedural process for fracturing and cleansing a viral pathogen from a pulmonary system, (FLiM) of a patient that has tested positive for a pulmonary viral pathogen, and the viral pathogen's constitution consisting of a lipid membrane, for example, the viral pathogen Covid19, by means of a FLiM performed by a Medical Professional (MP), utilizing potential permutations, MD/S (nPk) x ELT (nPk) and of at least: a continuous aqueous suspension, herein understood as; a Microcrystalline Castile Colloid (MCC), at least one medical device, a medically equipped operating theater, at least one computer and a network, and comprised of at least the steps of: diagnosing, determining, prepping, performing, diagnosing and following-up on the patient for FLiM medical procedure process.

An infusion pressure control system for ophthalmic surgery includes intraocular pressure detection means, arterial pressure detection means and a control unit operatively connected to the intraocular pressure detection means and the arterial pressure detection means and configured for calculating the mean ocular perfusion pressure value based on intraocular pressure and arterial pressure values provided by the intraocular pressure detection means and by the arterial pressure detection means, and for comparing the calculated mean ocular perfusion pressure value and at least one predetermined threshold value.

Systems and methods for automated assessment and monitoring of bodily fluids are disclosed. In one embodiment, a system for provisioning a treatment composition to a bladder of a patient includes: an irrigation bag that carries the treatment composition; a catheter configured for connecting the irrigation bag to the bladder; a flow regulator configured for controlling a flow of the treatment composition from the irrigation bag to the bladder; and a drainage bag in fluid communication with the bladder through a drainage tubing of the catheter. The drainage tubing is configured for draining urine from the bladder. The system also includes: a first sensor for detecting a first amount of the treatment composition in the irrigation bag; a second sensor for detecting a second amount of urine in the drainage bag; a third sensor for detecting a concentration of particles in the urine carried by the drainage bag; and a controller.

A tool is attachable to a bladder irrigation catheter. A body supports multiple fluid pathways between each of the catheter, a supply of irrigation fluid and a waste fluid collector. A syringe or other pressure and vacuum applicator accesses the pathways and powers irrigation flow. A supply port and intake port are connected to a supply pathway leading to the applicator. Similarly, a drain port and discharge port are connected to a drain pathway leading to the applicator. The supply pathway and drain pathway can be selectively blocked so that action of the applicator only drives supply or drain irrigation action. Check valves are located to provide proper fluid flow direction. Bypasses between the supply port and intake port and between the drain port and discharge port can be activated to bypass the supply pathway and drain pathway and allow for gravity flow bladder irrigation through the tool.
