A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

According to a preferred aspect, there is provided a measurement system (1) that measures the volume of a drug solution that fills a needle-shaped recess of a mold. A measurement unit (10) of the measurement system (1) measures respective heights of a plurality of measurement points which are stored in a storage unit (20) and are preset on a plane parallel to the mold, in a direction orthogonal to the plane. A surface shape calculation unit (30) calculates a three-dimensional shape of the surface of the drug solution on the basis of the heights of the plurality of measurement points measured by the measurement unit (10). A volume calculation unit (50) calculates the volume of the drug solution that fills the needle-shaped recess on the basis of the three-dimensional shape of the surface of the drug solution calculated by the surface shape calculation unit (40) and the shape of the needle-shaped recess of the mold.

摘要:
A connectable component module for a reduced pressure treatment system is provided. The module includes a housing with a rim, a recessed end surface, and an extension. A mounting assembly is fixed to the recessed end surface and includes extendable latches. The latches include a fastener bar that is flush with the rim when the latches are not extended. The module also generally includes a control system contained within the housing. The control system has a communication controller, a communication plug coupled to the communication controller and protruding through an aperture in the mounting assembly and recessed end, and a communication port coupled to the communication controller and exposed to an aperture in the extension.

A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.

Wearable breast pumps are provided which utilize compression to enhance milk expression. The breast milk expression systems herein can allow breastfeeding users to obtain milk discreetly and comfortably in the presence of others. These systems compress the breast at one or more locations, such as at a base of a breast and/or along inferior and lateral sides of a breast, to stimulate milk expression. Various components and methods for expressing milk can facilitate milk output. For example, vacuum can be used in conjunction with compression. For another example, one or more temperature sensitive component s can be utilized to improve milk secretion. In some embodiments, milk can be collected in a sterile custom storage container located around or beneath the breasts to facilitate wearability. After expression is complete, a quick-release valve can be used to detach the storage container from the pump and can prevent leaks.
