Examples relate to devices, systems, and methods for fluid collection, such as fluid. A portable fluid collection system may include a fluid collection container, a pump in fluid communication with the fluid collection container, a battery operatively coupled to the pump, and a pack. The pack may be sized and dimensioned to include at least the pump, the battery, and the fluid collection container therein. The pump may be configured to pull a vacuum on an interior region of the fluid collection container effective to draw fluid from a fluid collection device into the fluid collection container.

A disposable, hand-held, manually operated, and powered suction device for use in both emergent and non-emergent hospital and pre-hospital care settings evacuates media from body cavities created or formed.

A dual-chamber suction filtering device and filtering method, belonging to a surgical waste liquid collecting device, and solving the problem in the prior art that drainage fluid of an endoscope shaver system and a plasma surgical system is easily contaminated and cannot be separated in sections. The dual-chamber suction filtering device comprises a dual-chamber one-way valve (1), a switching valve (4), and a filtering branch (2) and a direct-passing main path (3) which are connected to each other in parallel, the water outlet of the dual-chamber one-way valve (1) being connected to the water inlet of the filtering branch (2) and the water inlet of direct-passing main path (3); the switching valve (4) is provided on the joint between the water inlet of the filtering branch (2) and the water inlet of direct-passing main path (3); the dual-chamber one-way valve (1) has a first drainage fluid system (5) setting, a second drainage fluid system (6) setting, and a dual-drainage fluid system (5, 6) setting, and the switching valve (4) has a filtering setting and a direct-passing setting. The dual-chamber suction filtering device and filtering method can be used for collecting and filtering drainage fluid.

Examples relate to portable urine collection systems and methods of use and assembly. The portable urine collection system (10) may include a urine collection device (12) configured to be positioned at least proximate to a urethra of a user, a conduit (17) in fluid communication with the urine collection device, a urine collection container (14) having an interior region, a pump (16) secured to the urine collection container and configured to promote urine from the urine collection device through the conduit into the urine collection container, and a sensor secured to the container and configured to detect a property relating at least to a volume of the urine in the urine collection container.

The present disclosure discloses a fluid collection box for phacoemulsification surgery, including a case composed of a front plate, a body, and a rear plate. The case communicates with a waste liquid bag. The body has a perfusion passage and a suction passage that are disposed independently. The perfusion passage is a sealed circulation cavity defined by a cover and the body. The circulation cavity communicates with a first connection port and a second connection port on the body for perfusion. There is a gap between the cover and the body. Connection and disconnection of the perfusion passage is controlled by pressing the cover. The suction passage is a pipeline that communicates a third connection port with the waste liquid bag, and performs perfusion by a peristaltic pump. The suction passage further communicates with a negative pressure regulating loop, to regulate pressure within the suction passage. According to the present disclosure, the perfusion passage and the suction passage are independently disposed, so that the two do not interfere with each other and work independently. Meanwhile, it is ensured that pressure within the perfusion passage is stable, thereby reducing changes of intraocular pressure, and improving safety during use.

Apparatuses, systems, and methods for optimizing fluid storage canisters for use in negative pressure therapy systems are described. A fluid storage canister includes a first wall and a second wall coupled to the first wall. The canister has a chamber disposed between the first wall and the second wall. The chamber is configured to be sealed from an ambient environment and to store fluid. A pathway is disposed between the first wall and the second wall. The pathway is configured to be open to the ambient environment. There is a barrier separating the pathway from the chamber. The barrier is configured to permit evaporated fluid in the chamber to transmit through the barrier into the pathway.

A device and method for removing by suction urine voided by a patient. The device includes an impermealble bag, a wicking pad, a spacer, and an adhesive patch. The bag includes an internal chamber and an entryway through which the penis of the patient is inserted. The wicking pad has a first portion located within the chamber and a second portion located outside the bag in communication with the ambient atmosphere. The adhesive patch secures the device to the patient. The bag includes a port at which regulated suction is provided to carry urine from the patient through the first portion of the wicking pad and out the port. Ambient air flows into the second portion to facilitate the flow of urine therethrough and to aid in drying the wicking pad. The spacer is located outside the bag for enhancing air flow through the second portion.
