The fluid communication assembly is configured to couple the first fluid port with a fluid source, couple the first fluid port with a suction source, and couple the second fluid port with the fluid source.

NEGATIVE PRESSURE DRAINAGE AND CLEANING SYSTEM FOR SUTURELESS CLOSED SKIN INCISIONS
20220218891 · 2022-07-14 ·

A negative pressure drainage and cleaning system for sutureless closed skin incision. The system comprises: irrigation device, which comprises a delivery pump and a first catheter partially probing into inner cavity of a subcutaneous incision at a preset depth and is used for delivering irrigation solution; a negative pressure device, which comprises a negative pressure source and a second catheter partially probing into the inner cavity of a subcutaneous incision at a preset depth; a control device, electrically connected to the irrigation device and the negative pressure device. The system can assist to implement the sutureless closure of a full-thickness tissue above the deep fascia of the skin, avoids horizontal scars on the skin surface caused by suture compression/cutting, and leaves no suture knots in the superficial fascia, thereby eliminating an important factor which causes colonization of bacteria and a main cause of recurrence of wound infection.

The fluid degassing apparatus includes one of a gas filter including a permeable membrane disposed in a fluid-tight housing, a centrifugal separator, and a multi-chamber system including a vacuum chamber and a fluid reservoir fluidly coupled downstream of the vacuum chamber.

System and method for monitoring and controlling intrauterine pressure using a pressure cuff
11389198 · 2022-07-19 · ·

A method of determining a pressure of a body cavity with a controller of a fluid management system includes determining a pressure and a volume of a cuff disposed about a collapsible bag, determining a volume of the collapsible bag based on the pressure and the volume of the cuff, and determining a pressure of the collapsible bag based on the volume of the collapsible bag. The method also includes calculating a fluid flow from the collapsible bag into a body cavity from the collapsible bag and determining a pressure of the body cavity based on the fluid flow.

DEVICES, METHODS, AND SYSTEMS FOR IMPROVED ENEMA AND RECTAL IRRIGATION PROCEDURES
20220226560 · 2022-07-21 ·

Methods of administering an enema to a patient utilizing a fecal management system are disclosed. Such methods may include providing the patient utilizing the fecal management system and providing an enema solution providing apparatus. The enema solution providing apparatus may include a bag containing enema solution, tubing, a tubing connector, and an adjustable clamp. The method may include clamping a catheter of the fecal management system between an irrigation port and an collection bag, engaging the tubing connector with the irrigation port, actuating the adjustable clamp to commence a flow from the bag containing enema solution into the patient through the catheter, completing the flow from the bag containing enema solution into the patient, disengaging the tubing connector from the irrigation port; and unclamping the catheter. Kits for providing an enema through a fecal management system and enema solution providing apparatuses are also disclosed.

SYSTEMS AND METHODS FOR PERCUTANEOUS DRAINAGE

System for percutaneous drainage of a drainage site includes a catheter, a drain tube, a first pump, a flush tube, a second pump, and a controller. The catheter includes a drain lumen defined by a first portion of a catheter wall and a septum, and a flush lumen defined by a second portion of the catheter wall and the septum. The flush lumen is separated from the drain lumen by the septum. The septum has at least one septal hole disposed therein such that the drain lumen and the flush lumen are in communication via the at least one septal hole. The catheter wall has at least one wall hole disposed therein such that the drain lumen is in communication with the drainage site when the distal end portion of the catheter is placed within the drainage site.

Fluid Management Systems and Methods

Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.
