The invention relates to a coupling component for a fluid coupling (1) for releasably connecting fluid-conveying components, in particular fluid-conveying components in medical equipment, wherein the coupling component comprises a coupling housing (14) through which a fluid channel (17) passes in regions and which is provided with a coupling recess (7) that is sunken into a surface (15) of the coupling housing (14), wherein a channel opening (18) of the fluid channel (17) ends at an end face (19) of the coupling recess (7). According to the invention, it is provided that the channel opening (18) is covered by a membrane seal (4) which is made of a resilient material and through which a fluid gap passes (8) that is designed such that the membrane seal (4), when in a resting position, seals the channel opening (18) and, when in an operative position, opens the channel opening (18), wherein at least one yielding depression (29) is formed in the coupling recess (7) adjacently to the channel opening (18), which depression is designed for an yielding movement of a region (36, 37) of the membrane seal (4) when the membrane seal (4) transitions from the resting position into the operative position.

A breakaway medical tubing connector and method for joining two sections of medical tubing includes a pump side member and a patient side member positioned axially opposite from the pump side member. The patient side member has a first channel disposed within the pump side member and a first valve disposed within the first channel. The pump side member has a second channel disposed within the patient side member and a second valve disposed within the second channel. The first valve may be an active valve and the second valve may be a passive valve. A securing bar may be disposed on the pump side member and a securing arm may be disposed on the patient side member for providing a detachable coupling of the two members.

A fully implanted automatic disorder response system is devised to act as a backup “immune” system, automatically detecting and dispensing an enzyme, for example, deficient due to an inborn error of metabolism. In response to a disease, the agent released is one or more drugs. By directly pipeline-targeting agents through a closed system of drug reservoirs, fluid and electrical lines, and leak-free, durable, and safe tissue connectors to the site of disease, the system achieves a level of efficiency critically superior to the systemic dispersal of an agent into the circulation, fundamentally liberalizing the use of drugs. In comorbid disease, each morbidity is assigned to an arm or channel in a hierarchical control system. Beginning with symptomatic indicia sensors, data is analyzed and passed up through successively higher-level nodes that generate a cross-morbidity view passed up to an implanted microprocessor which effectuates a release of drugs calculated to optimize homeostasis.

A stopcock, comprising a housing element defining a central bore and at least first, second and third ports; and a handle element which is selectably positionable relative to the housing element; at least one of the housing element and the handle element defining: a first fluid flow passageway communicating between two of the at least first, second and third ports; a second fluid flow passageway communicating between at least two of the at least first, second and third ports, and a fluid flow guide associated with the second fluid flow passageway, the fluid flow guide extending radially towards an inner facing wall of the central bore.

A method of delivering a urological device includes providing a catheter and a urological valve that can be retained within the catheter; advancing the catheter toward a bladder neck of a user; withdrawing the catheter from the user; and deploying the urological valve out of the catheter into the bladder neck or urethra of the user.

A check valve, including a valve and a valve support surface, to permit a fluid to move through the check valve in a first direction and resist a fluid flow through the valve in a second direction, the valve having a valve diaphragm and an isolating bridge, with a portion of the valve engaging against valve support surface to resist deformation or stretching of the valve when a backflow of fluid into the check valve occurs. The valve support surface having a first support surface and a second support surface, and the valve positioned with the valve diaphragm spaced apart from the first support surface, and the isolating bridge spaced apart from the second support surface.

A swabable valve (10) comprising a valve stem (100) that collapses into a valve body (12), said valve body (12) including a generally cylindrical reduced diameter section (18) having a generally circular rim, said valve stem (100) having a generally cylindrical reduced diameter portion (38) that extends fully into said cylindrical reduced diameter section (18) of said valve body (12), said cylindrical reduced diameter portion (38) including a through-slit (52) that opens when said valve stem (100) collapses into said valve body (12), said valve stem (100) having a concave curvilinear surface (102) that is substantially flush with said circular rim of said cylindrical reduced diameter section (18) of said valve body (12) when said valve stem (100) is not collapsed into said valve body (12); said concave curvilinear upper surface (102) of said valve stem (100) extending rim-to-rim within said cylindrical reduced diameter section (18) of said valve body (12).

A pump apparatus and method for extracting breastmilk is disclosed. A pump head comprises a funnel-shaped breast shield portion and a neck portion leading to a collection container. A deformable elastic component is sealed within an opening formed in the neck portion and manipulated to engage the user's nipple to simulate the suckling of an infant. The deformable elastic component is configured to move into the interior volume of the neck portion under an applied positive pressure to compress the nipple and control nipple edema. The deformable elastic component is also configured to move away from the axial center of the neck portion under an applied negative pressure to create suction and extract breastmilk in a manner that closely replicates the suckling of an infant. The pump may also include another deformable elastic component to stimulate a Milk Ejection Reflex (MER).

A medical valve which is able to more reliably support an outer peripheral part of an elastic valve body with respect to a housing, and prevent a problem of the elastic valve body becoming dislodged inward. A medical valve includes an elastic valve body with annular grooves formed thereon and a tubular support part formed at an outer peripheral side of an annular joining part positioned between the annular grooves. Inside and outside holding parts engage the annular grooves provided to the valve inside and outside surfaces of the annular joining part. The outside holding part and inside holding part are provided to an opening member, and with the tubular support part, a part projecting inward in an axial direction is sandwiched and supported between the inside holding part and outside holding part.
