The present invention is a compact and hands-free human breast milk collection device that fits into a mother's existing nursing or standard brassiere. The invention can be attached to a conventional electric or manual pump for active milk collection and also can be used without a pump for passive milk collection. Additionally, the invention can be used for collection of hand-expressed milk. The invention comprises a breast adaptor which, in an embodiment, has at one end a funnel-shaped inlet coupled to a reservoir, wherein when the breast is inserted into the breast adaptor, the breast milk is expressed into the reservoir through a unique valve assembly and the milk is stored in the reservoir until the device is removed and the collected milk emptied into a container. In an embodiment, the valve assembly is mounted concentrically on a second end of the breast adaptor. The valve assembly alternately opens and closes communication between the breast adaptor and the reservoir. The valve assembly further includes an overflow chamber and a baffle structure to prevent backflow of milk into the pump and associated vacuum or suction line. The invention, in an embodiment, also includes a unique connection apparatus that enables the vacuum hose of the disclosed breast milk collection device to be sealingly attached to a vacuum hose of varying sizes attached to a vacuum pump mechanism.

An enteric fistula healing device, configured for application over a fistula or other wound to physically separate the fistula from the remainder of the wound area, such that any effluent from the intestine or bowel, or other enteric substances, that pass through the fistula are prevented from communicating with the wound area. The device is configured to collapse from a first height to a shorter second height.

The invention discloses a urine drainage device, a drainage control device, a drainage control system and a urination method. The urine drainage device comprises a urine inlet, a urine outlet and a bladder bionics unit, wherein the bladder bionic unit comprises a main part forming a liquid storage cavity, a first pressure transmission surface and a second pressure transmission surface, wherein the liquid storage cavity is communicated with the urine inlet and the urine outlet via a connecting pipeline, and the first pressure transmission surface and the second pressure transmission surface deform along with the change of the pressure of urine in the liquid storage cavity; a connecting lower pipeline is provided with a first action region and a second action region which are affected by external forces; when the first action region and the second action region are synchronously affected by the external forces, the liquid storage cavity and the urine outlet are blocked; and the liquid storage cavity is communicated with the urine outlet when any one external force on the action regions is eliminated. The change of the pressure of the urine in the liquid storage cavity of the urine drainage device can be represented through the deformation of the pressure transmission surfaces, and further whether the urine is drained or not is determined according to the deformation capacity of the pressure transmission surfaces, so that the function assisting a patient to drain the urine is achieved, and the structure is simple and scale production is applicable.

A surgical drain device includes an adhesion matrix of biodegradable polymer material and a plurality of drain tubes attached to the matrix. The device is implanted within a surgical wound to treat the presence of seromas, for example, and is used to promote drainage, tissue adhesion, and wound closure. The drain tubes converge into a common collection tube that leads wound fluid outside the body under gravity feed or negative pressure applied to the collection tube. The matrix contains an array of apertures that allow tissue contact across the device. The device also can include a coating of surgical adhesive and a tissue anchoring system of hooks or barbs. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.

Described herein is an automated fluid drain control apparatus and method which comprises a first collection chamber which is connected to a drain that has been inserted into the subarachnoid area in lumbar region of the body. The volume of fluid into the first collection chamber is controlled as a function of time by being constantly measured such that too much fluid will not be drained from the body.

A medical, post surgery fluid drainage system, such as for use by a mastectomy patient, that allows the wearer / patient to discretely and safely secure and wear the system under clothing. The system includes a mesh fabric pouch having front and rear walls secured together along a bottom edge and along the sides with an open top edge. Inside the pouch are plural fluid receiving bulbs or receptacles. Connected to the bulbs are a like plurality of drain lines or tubes to allow drainage of fluid from plural chest incisions to the bulbs. Further, attachment mechanisms are included to removably secure the pouch to the body of the wearer / patient.

In one embodiment, an exsanguination preventing device includes a collection container having an inlet configured to receive blood from a patient and an outlet configured to discharge the blood; a pump operatively coupled to the collection container; a conduit fluidly coupled to the collection container, which receives the blood from the collection container, the blood being moved by the pump; and an insertion device, which delivers the blood from the conduit to a bodily part of the patient. The collection container is configured to be sealingly coupled to a wound on the patient and air entrapped within the exsanguination preventing device is removed by an air removal system, such to prevent unwanted discharge of air into the bodily part of the patient. All the components of the exsanguination preventing device are sized such to make it portable in a pocket of a garment or backpack of a soldier.
