A blood collection canister assembly enables a user to collect and transfer blood and includes liner and lid assemblies. The liner assembly is formed from a flexible liner material and defines an inner liner space. The lid assembly includes a primary lid portion attached to an upper mouth of the liner assembly and includes a series of ports. The series of ports may include a vacuum port, a patient port, a transfer port, and an additive port. The vacuum port is communicable with a vacuum line for directing blood transfer from a patient via the blood collection canister assembly. The patient port receives directed blood transfer from the patient, and the transfer port transfers collected blood to a separate reservoir for further processing. The blood collection canister assembly is usable in either an upright, first configuration for collecting and transferring blood or an inverted, second configuration for transferring collected blood.

The present invention relates to a blood recirculation device. More particularly, the present invention relates to a blood recirculation device capable of continuous blood suction and capable of minimizing mechanical damage to the blood during such a process. The blood recirculation device according to the present invention repeats suction with one side unit and repeats a process of transferring stored blood with the other side unit, thereby being capable of continuous blood suction and capable of efficiently supplying suctioned blood to an erythrocyte washing system of an autologous blood transfusion machine or a cardiopulmonary bypass machine.

A removable manifold for a medical/surgical waste collection system. The manifold is dimensioned to be mounted to a receiver integral with the system. The manifold includes a includes at least one fitting through which waste is drawn into the manifold. The fitting opens through an inlet port into a void space internal to the manifold. The manifold includes a drip stop.

Vacuum pump (18) for a medical aspirator (10), the pump (18) comprising a tubular member (20); a piston (22) slidably arranged within the tubular member (20); a piston rod (24) connected to the piston (22); and a coupling mechanism (36) for detachably and functionally connecting the piston rod (24) to a motor (38) for driving the pump (18), wherein the piston rod (24) is configured to reciprocate linearly during operation of the pump (18).

A flapper valve assembly with a hub to which plural flapper valves are pivotally attached. The hub includes a through hole to which a fastening component can be attached. On each of the major faces of the hub a rib extends circumferentially around the through hole. The ribs are compressible so as to provide a seal around the through hole. In many versions of the invention, the hub, the ribs, the hinges and valves are formed from a single piece of compressible, flexible material. Often in these versions of the invention, the hinges have a cross-section thickness greater than the thickness of the hub and valves.

A medical/surgical waste collection rover includes a first waste container disposed on a portable cart and receiving waste under the influence of a vacuum. A fluid measuring system includes a float element disposed within the first waste container, and a controller causing liquid in a reservoir disposed on the cart to prefill the first waste container and subject the float element to an initial lifting to a zero point level. The fluid measuring system determines a volume of contents within the first waste container based on a position of the float element relative to the zero point level. The fluid measuring system may include a sensor rod extending through the first waste container and a second waste container disposed on the cart and separated from the first waste container by a transfer valve. Methods of estimating the volume of liquid and/or medical/surgical waste within the waste container are also provided.

A system, method, and apparatus for the collection of surgical/wound fluid from a subject patient with the capability of simultaneous fluid removal from a plurality of such wounds and/or wound through the utilization of a single pump device worn by such a patient. Such a system, method, and apparatus allow for such a single pump device to collect surgical/wound fluid within a single site collection component attached to or associated with such a single pump device. Multiple fluid transfer lines may be incorporated with the single pump device leading to such plurality of wounds and/or wound sites for greater versatility and comfort for the subject patient, as well as cleaner removal capabilities than in the standard apparatus systems and method currently undertaken within the industry.

A system (1) for collecting liquid, including a main collecting chamber (10), a main duct section (11, 12, 13) connected to the main collecting chamber (10) in a fluid-communicating manner, and an auxiliary collecting chamber (20, 30, 40). The system (1) has an auxiliary duct section (21, 38, 39) connected to the auxiliary collecting chamber (20, 30, 40) in a fluid-communicating manner for connection to the main duct section (11, 12, 13). The main duct section (11, 12, 13) and the auxiliary duct section (21, 38, 39) form a duct (35, 36, 37) when the main duct section is connected to the auxiliary duct section. A water-soluble closing component (14, 15, 16) closes the duct (35, 36, 37). A hygienic collecting device for liquid, which has a short evacuation time and a flexible collection volume, is provided with the system (1).

A surgical collection assembly for filtering material from liquid obtained during surgery. A jar having an inlet and an outlet each adapted for connection to a suction line. A set of orientation features to position an upper portion of a collection basket within the jar such that an upper portion of the collection basket does not impede a flow of material entering the jar through the inlet. A bottom surface with a pattern of recessed paths in the bottom surface, the pattern of recessed paths connected to the outlet. A plunger assembly that may be reversibly attached to the jar so that a distal end of a plunger may be used to compress collected material within the collection basket to help remove fluid from the collected material. For certain uses, the surgical collection assembly may have a simple jar lid without an integrated plunger.
