Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise positioning a dressing interface having a pH sensor, a temperature sensor, a humidity sensor, and a pressure sensor at a tissue site, and applying reduced pressure to the dressing interface to draw fluids from the tissue interface in contact with the sensors to sense the pH, temperature, humidity, and pressure properties of the fluids flowing from the tissue site. The method may further comprise providing fluid data indicative of such properties to a processing element for processing the fluid data, and transmitting the data to another component in the system.

Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound dressing. The wound dressing can comprise an absorbent material, an electronics unit comprising a negative pressure source, the electronics unit integrated within the wound dressing and at least partially encapsulated by a flexible film. The electronics unit can include translucent or transparent components that allow light to travel through to reach adhesives or coatings on the electronic components that would otherwise be obscured.

Microbubbles detached from a blood circuit and a blood purification unit are discharged with the use of a backflow generated at the instant that a roller of a blood pump releases a squeezable tube. In a normal rotation step, a region filled with a priming solution after a priming step is closed by a closing unit, and a rotor of a blood pump is rotated normally until a roller of the blood pump releases a squeezable tube to generate a backflow. After the backflow is generated at the release of the squeezable tube by the roller of the blood pump, bubbles are moved by reversely rotating the rotor while disabling the closing by the closing unit. Thus, the bubbles are discharged through a discharge unit.

Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a distal portion of a catheter proximate to the clot material within the blood vessel. The method can further include coupling a pressure source to the catheter via a tubing subsystem including a valve or other fluid control device and, while the valve is closed, activating the pressure source to charge a vacuum. The valve can then be opened to apply the vacuum to the catheter to thereby aspirate at least a portion of the clot material from the blood vessel and into the catheter.

An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

A vacuum sponge system, comprising: a sponge having an outer surface, a proximal end and a distal end, spaced from the proximal end in an axial direction of the sponge; a drainage tube disposed partially in the sponge, and is in fluid communication with the sponge; the drainage tube is connectable with a vacuum pump such that a pressure is applicable to the outer surface of the sponge; and a delivery member having an outer surface and extending in an axial direction of the sponge and adapted to establish a fluid communication between a region from the distal end of the sponge and region from the proximal end of the sponge. The pressure provided by the pump via the drainage tube is applied to a vicinity of the outer surface of the delivery member and the outer surface of the sponge. The delivery member is disposed partially radially outside of the sponge.

An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

The present disclosure, when used by a live actor, may allow users to safely simulate hemorrhaging in some of the most challenging blood vessels in the most challenging anatomical locations such as the carotid artery, the axillary artery, and the femoral artery. The present disclosure may further provide the ability for users to safely perform hemorrhage control procedures, such as compression and ligation. The simulated wound of the present disclosure may be compressed to control hemorrhage. The simulated wound receptacle of the present disclosure may be packed with hemostatic or simple gauze to control hemorrhage. The simulated blood vessel of the device may be ligated with hemostats or other ligating instruments or material and bandaged with pressure dressings to control hemorrhage.

A rectal drainage appliance is disclosed comprising a tubular element having an inflatable balloon at a distal end for anchoring the appliance in the rectum. The appliance includes one or more of: (i) first and second auxiliary lumens communicating with the inflatable balloon to provide independent inflation and pressure monitoring paths coupled to the balloon; (ii) a pressure state indicator defined by a mechanical element configured to flip between first and second states or shapes responsive to sensed pressure; and (iii) a collapsible auxiliary lumen larger than the inflation lumen, and configured to permit admission of irrigation fluid. The pressure state indicator may also be used in intestinal drains.

A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by utilizing a stabilizing structure that preferentially contracts to provide for movement of the tissue. Some embodiments may utilize a protective layer, such as a mesh or net layer, attached to a top surface of the stabilizing structure. The protective layer prevents a drape positioned over the stabilizing structure from being drawn into cells of the stabilizing structure, and permits visualization of the collapse of the cells.
