An automatic drainage device comprises a drainage container separated by a partition plate into a fluid storage cavity provided with a connecting pipe and a fluid discharge channel provided with a fluid discharge outlet. The partition plate is provided with a fluid drainage outlet that connects the fluid storage cavity to the fluid discharge channel. The device further comprises a movable gasket disposed below the partition plate for closing the fluid drainage outlet, and a control device comprising a remote control receiving module or a control device configured to monitor a liquid level in the fluid storage cavity, to move the movable gasket to open or close the fluid drainage outlet. The automatic drainage device remotely activates the control device by a remote control receiving module or by monitoring the status of the liquid level, to control the opening and closing of the fluid drainage outlet.

A portable pump is provided for negative pressure wound therapy for drawing a vacuum from a wound site via a tube. The pump includes an inlet configured to attach the tube from the wound site; a canister in fluid communication with the inlet for collecting fluids drained from the wound site; and a manually-actuated pump mechanism for creating the vacuum. The pump mechanism includes a vacuum chamber in fluid communication with the canister; a piston disposed in the vacuum chamber; and a pump handle coupled to the piston to move the piston in the vacuum chamber between first and second positions to create the vacuum. The pump handle moving between a retracted position and an extended position. The piston is in the first position when said pump handle is in the retracted position and is in the second position when said pump handle is in the extended position.

The present invention is related to a medical aspirator and, in particular, to a medical aspirator comprising: a floor plate; a pressure plate disposed a certain distance away from the floor plate, and defining a discharge hole opened and closed by an opening/closing means; a coil spring installed between the floor plate and the pressure plate; a sealing membrane connecting the edges of the floor plate and the pressure plate, and defining a receiving space capable of receiving bodily fluid between the floor plate and the pressure plate; and a drainage tube connected to the pressure plate, for guiding bodily fluid generated from the body to the receiving space, and including a check valve therein enabling the fluid to flow only in the direction from the body toward the receiving space, wherein the medical aspirator has the effect of preventing contamination from outside air of bodily fluid extracted from the body and stored in the receiving space.

This disclosure describes devices and methods used to inject or aspirate fluid into or from various regions of the human body, such as the anterior chamber of the eye. The disclosed devices and methods provide improvements over conventional devices and methods in that an operator can perform a procedure using the disclosed device without an assistant. The disclosed devices and methods allow one-handed injection or aspiration of fluid into or from body tissue, and provide means for controlling the volume of injected or aspirated fluid.

A system for processing fluids and filling a container with a product includes a disposable fluid circuit and reusable hardware configured to accept the disposable fluid circuit. The disposable fluid circuit includes a spinning membrane separator, first and second syringes, and a flow control cassette. The reusable hardware includes a drive coupled to the spinning membrane separator, first and second syringe pumps, the first and second syringes coupled to the first and second syringe pumps respectively, and a controller. The system also includes a syringe pump for filling low-volume containers, which syringe pump may be one of the first and second syringe pumps, or may be a third syringe pump. The syringe pump for filling low-volume containers may include a filtered vacuum/pressure source and a position detector.

An apparatus for providing negative-pressure therapy may comprise a negative-pressure chamber and a pneumatically-actuated service timer, which can be used to indicate an expiration or other service condition of the apparatus. The apparatus may further comprise an actuator operable to engage a timer fluid with a migration medium. The timer fluid and the migration medium may be selected so that migration time through the migration medium corresponds to an expiration condition of the apparatus. The timer may also provide indicia of migration progress or termination.

The present invention provides a manually operated negative pressure wound treatment (NPWT) apparatus for suction of bodily fluids using the negative pressure generated by means of manual pressing. The NPWT apparatus is made of two parts: [1] top functional part; and [2] bottom collector part. The top functional part is made of a pressing mechanism attached to a bellow enclosed within an enclosure. The bellow is connected to the wound dressing using an external medical tube through a one-way check valve, wherein the negative pressure gets created within the bellows when compressed by manually pressing the mechanism. The negative pressure of the bellows sucks the bodily fluid from the wound, which promotes a new blood supply, cleaning infection, and accelerates healing dramatically. The bottom collector part is attached with the bellow through the internal one-way valve, wherein the collector collects the fluid from the bellow when the piston is pressed in the next cycle. Pressure levels and wound conditions are measured and transmitted to the user's smart device, in order to enhance treatment monitoring and efficacy.

This invention relates to the design of tissue covering elements for use in vacuum assisted tissue apposition systems, wherein the geometry of the covering elements favours the application of contractile forces over compressive or extensive forces at the tissue interface.

A fluid drainage device which includes a fluid-receiving volume, a cover which is movable between a first limiting position at which an inlet port is in fluid communication with the volume and a second limiting position at which an outlet port is in fluid communication with the volume, a piston which is movable inside the volume between a first position and a second position, a handle which is moveable in a first direction to cause the piston to move to the first position and to store energy in a spring so that, when the cover is in the first limiting position the piston is moveable by energy released from the spring to reduce pressure in the volume, allowing fluid flow through the inlet port, and wherein movement of the handle in a second direction causes the piston to move to the second position thereby expelling fluid from the volume.
