    摘要： A container is provided that is disposable, for first collecting blood delivered from a patient, preferably by a vacuum draw of blood into a container, and then the blood in the container is treated. The treatment is provided by an at least partial a back-and-forth or reciprocating motion of blood along membranes, such that filtrate components of the blood pass through the membrane walls and are collected, whereby retentate components of the blood are retained, with the back-and-forth motion being provided by a substantially constant vacuum draw, that provides a pumping action by a diaphragm pump. A replenishment liquid is automatically added, substantially proportional to the amount of filtrate components of the blood that are withdrawn. The membranes are protected by a device which removes body fat or other potentially harmful materials. Various automatic techniques are also supplied to control the amount of replenishment liquid being added, and the amount of retentate components of the blood that are retained. Various safety features are also provided.

    摘要： A gauge is provided, preferably for patient use, in which a piston moves linearly within a gauge body against the force of a spring. A diaphragm separates the sensing side of the piston from the clean or atmosphere side of the piston. The diaphragm rolls against the piston and the wall of the chamber during changes in pressure, and does not interfere with accuracy of the readings. Dampening is provided out of the patient fluid stream. The sight glass through which measurements are read produces an optical magnification. A baffle prevents entrained particles from the patient from entering the gauge in significant amounts. A surface-to-surface seat enables the gauge to be mounted as a saddle seat on a duct, regulator or the like.

    摘要： A process for the collection of blood from a body cavity requires a controllable flow conduit having an inlet and an outlet. The inlet of the conduit is placed in a body cavity from which blood is to be withdrawn. The outlet of the conduit is connected to the inlet of a blood collection apparatus. The apparatus includes an apparatus body having a first opening therein for connection to a source of suction and a gas-transmitting water seal. The apparatus also includes an autotransfusion collector for collecting and storing blood for optional blood reuse. The collector includes an outer receptacle and an inner receptacle. The inner receptacle includes at least one interior cavity and at least one substantially flexible wall at least partially enclosing the at least one interior cavity. The apparatus also includes a conduit for placing the source of suction in fluid communication with the interior cavity through the water seal. An inlet conduit communicates with the interior cavity and the body cavity for carrying blood to the inner receptacle when suction is applied to the first opening in the apparatus body. Preferably, the outer receptacle is substantially rigid and the collector further includes at least one intermediate cavity between the outer receptacle and the inner receptacle. In a preferred embodiment the intermediate cavity is sealed against fluid communication with the atmosphere.

    摘要： A suction drainage device is provided, particularly for collecting liquids and any solids that may be carried therewith from a cavity of a body. Suction draws air or other gases from a collection chamber, and liquid and entrained particles from the cavity are drawn into a collection chamber. The device also has a water manometer. A liquid seal is also provided through which is drawn air and other gases from the collection chamber. A fluid control valve-like device is provided between various portions, chambers, and conduits of the device, and preferably between the device itself and atmosphere, such control device preferably being a gas permeable, liquid impermeable membrane, but optionally comprising a baffle. A facility is provided for breaking up bubbles of air at the inlet to the water in the manometer. Sampling openings are also provided, as are visual indications in the event of an upset of the device, an optional visual indication for magnifying observation of an air leak, an atmosphere opening on multiple planes to prevent its accidental blocking, an optional connection to a pump for auto-transfusion purposes, further a double collection chamber for simultaneously handling two cavities, and a removable calibrated tape for recording and maintaining a permanent record of patient progress.
