An artificial lung in a circulation apparatus can be monitored and be maintained in a safe condition without manual assistance. As an extracorporeal circulation mode starts, it is determined first whether or not gas exchange of the artificial lung is carried out within a normal range, based on oxygen concentration which is detected by an oxygen sensor positioned at a downstream place in the artificial lung. If the gas exchange is carried out within the normal range, an estimated value for gas supply volume of a gas blender is maintained. When oxygen concentration exceeding the normal range is detected, the gas blender is controlled so as to revise the gas supply volume downward. In addition, when oxygen concentration falls below the normal range, the gas blender is controlled so as to revise the gas supply volume upward.

An apparatus for moving a fluid to or from a cavity on a body of a human or mammal patient. The apparatus comprising a fluid movement device, an energy source adapted to supply energy to said fluid movement device and at least one connecting tube having a tube end. The at least one connecting tube being connected to the fluid movement device. The apparatus further comprises, a flexible patch. The fluid movement device and the at least one connecting tube forms a fluid moving arrangement adapted to be implanted inside the body of the human or mammal patient. The fluid movement device is adapted to move fluid from a treatment area via the at least one connecting tube to a delivery area. The flexible patch comprises a net structure adapted to be overgrown by human fibrotic tissue hen implanted in the patient

A negative pressure wound therapy (NPWT) device includes a canister, a pump, a filter, and a control unit. The canister is configured to collect wound exudate from a wound site. The pump is fluidly coupled to the canister and configured to draw a vacuum within the canister by pumping air out of the canister. The filter is positioned between the canister and the pump such that the air pumped out of the canister passes through the filter in a first direction. The control unit is configured to operate the pump and to purge the filter by causing airflow through the filter in a second direction, opposite the first direction.

A failsafe system for a medical fluid procedure, comprising a medical fluid processing apparatus comprising a sealer and a programmable controller driven by software, wherein the programmable controller is programmed to recognize a failure event from input from hardware components of the medical fluid processing apparatus. The system also comprises a disposable fluid circuit configured to associate with the medical fluid processing apparatus and comprising a tubing segment configured to fit within the sealer. The programmable controller is configured to seal the tubing segment by activating the sealer surrounding the tubing segment in response to an occurrence of the failure event.

A method for clearing a wetted hydrophobic filter includes a first step in which the air permeability of the hydrophobic filter is monitored, and a second step in which the hydrophobic filter is cleared by means of a connected air pump, if it is detected that the hydrophobic filter is clogged. An apparatus for performing this method includes a pressure sensor and an air pump connected to an air separation chamber via a conduit, and a control and monitoring unit configured to actuate the air pump in order to clear the hydrophobic filter.

A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway, a filter provided in the blood flow passageway for filtering blood clots, and a cleaning device for cleaning the filter. By means of such blood clot removal device and system, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.

A medical device includes a first valve and a second valve. The first valve includes a manifold having a first opening, a second opening, and a third opening, and an element movable within the manifold and spring-biased to close the first opening. When biased to close the first opening, air flows from the second opening to the third opening. The second valve is configured to provide a flow of pressurized gas to the first valve, to move the element to close the third opening. The first valve and the second valve are configured, upon moving the element to close the third opening, to interrupt the flow of air from the second opening to the third opening and to allow the flow of the pressurized gas to exit the second opening.

A fluid extraction implantable system shaped and sized to be implanted in a patient, including: a fluid extraction chamber having a flat and thin shape connected to a draining tube and including at least one external flat surface, wherein the at least one external flat surface is configured to be attached to a tissue surface when a negative pressure is applied on the draining tube, wherein the chamber extracts fluids from the tissue by applying the negative pressure through the flat surface on the attached tissue surface.

The invention relates to providing novel functions to the coaxial breathing circuits which at present do not comprise water traps, by adding a closed system water trap designed to have an inkwell shape and a lung pressure measurement port to said circuits wherein the fluid collected in the bottle section can be discharged without having to open the bottle by means of a drainage luer port located at the base of the bottle and a needleless apparatus that has been inserted into the port, and an injector.

The present disclosure provides devices and methods for processing and harvesting adipose tissue. The present disclosure provides improved devices, systems, and methods for harvesting, processing, and filtering adipose tissue for autologous fat transfer procedures. The features of the devices and systems of the present disclosure increase efficiency and sterility of adipose tissue processing by reducing the need for users to interrupt the procedure to adjust some part of the system, such as unclogging filter pores or adjusting tubing.
