A central nervous system drain drains the subdural space intracranially or the postoperative epidural space in the spine. The drain includes one or more lumens that communicate with the outside environment through openings in the distal portion of the drain. The drain also includes a flat bottom wall without any openings which is placed on the brain surface in the subdural space intracranially or the epidural surface in the spinal canal after a laminectomy. The openings in the top wall and/or side surface walls allow for drainage of fluid and/or blood in the subdural space or postoperative wound in the spine.

Embodiments disclosed herein are directed to support structures for drainage tubes to relax dependent loops and mitigate fluid pooling. Embodiments include support structures configured to receive an elastic tube and impart rigid or malleable properties thereon. These properties allow a clinician to position the tube to provide a consistent negative incline. Embodiments of support structures include an interlocking segmented tube, a bi-stable or mono-stable support structure, a jacket support structure, or a magnet support structure. Embodiments further include a malleable wire disposed within a wall of an elastic tube, or portions of a tube displaying differing elastic, malleable, or rigid properties. Also disclosed are magnetic peristalsis devices configured to urge fluid through a tube lumen.

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 can be used with a negative pressure system to further improve the drainage band can also be used with a wound dressing. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.

A negative pressure therapy system is provided for inducing negative pressure in a portion of a urinary tract of a patient, the system including: (a) at least one ureteral catheter configured to be positioned within a ureter and/or kidney of a patient; (b) one or more sensor(s) configured to determine information about urine produced within a urinary tract of the patient; and (c) a controller configured to increase urine production of the patient by adjusting one or more operating parameters of a negative pressure source for inducing negative pressure through the at least one ureteral catheter into the urinary tract of the patient, based at least in part upon the information determined by the one or more sensor(s).

A urinary bladder irrigation device includes: a first pipe, a second pipe, a third pipe, a liquid supply member, a liquid collection member, a detection member, and an elevation member. The first pipe has a first opening at one end thereof. The second pipe has a second opening at one end thereof. The third pipe has an end connected to another end of the first pipe and another end of the second pipe and has a third opening at another end thereof. The liquid supply member is connected to the first opening. The liquid collection member is connected to the second opening. The detection member is positioned in the second pipe. The elevation member accommodates the detection member.

A collection system for collecting outflow from a hysteroscopic surgical procedure includes a collection vessel and a mounting stand. The collection vessel defines an internal volume and includes a top portion and a bottom portion. The collection vessel is transitionable between a collapsed configuration and an expanded configuration. The mounting stand includes an upper retainer and a lower retainer. The upper retainer of the mounting stand is configured to retain the top portion of the collection vessel and the lower retainer of the mounting stand is configured to retain the bottom portion of the collection vessel. The upper and lower retainers are configured to retain the collection vessel thereon in the expanded configuration.

The described invention provides a blood collection and autotransfusion container, which provides fast, efficient, safe blood collection and blood or blood products transfusion.

Irrigation and/or aspiration devices and methods may be configured to aspirate and irrigate alone, sequentially, or concurrently. The devices and methods may provide a base with a removable head, and adapted for partial or complete separation of the irrigation and aspiration functions. The devices and methods can be configured to aspirate and/or irrigate the nasal and sinus cavities. The devices and methods may be manually and/or automatically controlled. The devices and methods may include removable, and/or replaceable, and/or refillable, and easily cleanable reservoirs for aspirant and irrigant. The device head and/or aspirant reservoir may comprise a diagnostic device, i.e., test device and/or container after use of the devices and methods.

A fluid collection device includes an upper edge portion having a first end of a collection container having an outer surface where the upper edge portion defines an open top end. At least one fastening device may be attached to the outer surface of the collection container. A vacuum hose coupled to an outlet port extends from a second end of the collection container. A vacuum source applies a vacuum to the collection container through the vacuum hose.

A control system and method for automatically adjusting the height of an external ventricular drain from a patient. The height of a pole supporting the bag into which the fluid is drained can be varied, increased or decreased, as driven by a motor. A drip chamber and collection bag that receive the fluid from the patient are attached to the height variable pole. An external fluid pressure tube is coupled to the patient at one end and to a pressure sensor at the other. The pressure sensor is coupled to the height variable pole. The system includes a feedback loop that adjusts the height of the external ventricular drain (EVD) to match the height of the patient's head. As the patient's head moves up or down, the variable height pole moves up and down a corresponding distance to maintain the patient's intracranial or intraspinal pressure, and therefore the cerebrospinal fluid (CSF) drainage rate, at a preset value.
