摘要： A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.

摘要： A medical treatment system is configured to output a predefined test pattern and to receive the signal by way of a microphone in order to test the volume and quality of the audio output in order to ensure the output audio signals effective to wake a sleeping patient. The failure of a processor to confirm the volume and fidelity of the audio output as well as the timeliness of the test pattern causes the processor to deny the resumption of a treatment and to generate an error signal.

摘要： A frangible connector has a first side that forms a female luer when a second side is fractured at a predefined break line. The second side may be connected to a fluid circuit, for example, a source of medical treatment fluid such as dialysate.

摘要： A system for preparing a medicament for use by a medicament user includes a proportioning machine with a controller and pumping and clamping actuators to engage a fluid circuit having pumping and clamping portions that engage with respective actuators of the proportioning machine. The fluid circuit includes a mixing container that is initially empty and later filled with two different concentrated medicaments from different concentrate containers and with purified water. The proportioning machine is configured to receive purified water and to mix it with the concentrated medicaments to produce a medicament and to output the medicament to a medicament consumer in such a way that to the medicament consumer the medicament appears to be provided from a bag of medicament. Custom mini batches of medicament may be produced by varying the amount of the concentrates and water.

摘要： A method of making a needle guard includes providing a mold having a portion defining a volume, the volume being a hollow cylinder with non-uniform walls with a pair of slots therein, the slots being open at one end and closed at the other end, the pair of slots having a major portion of constant width. The walls are thicker at the other end than at the one end. The method includes filling the volume with polymer and releasing a molded part from said mold and cooling a molded part resulting from the filling and releasing such that temperature that the widths of the pair of slots is non-uniform after cooling. The needle guard has upper and lower jaws defining a channel and coming together at a hinge. A winged needle can be inserted between the jaws, with the wings of the winged needle passing through slots between the jaws.

摘要： A peritoneal dialysis device includes a disposable tubing set that includes a fill line with a patient access connector at one end and a dialysis fluid receiving end opposite the patient access connector end. The device also includes a fill-side pressure measuring sensor attached at the fill end and forming a disposable component of the tubing set and a patient-side pressure measuring sensor located at the fluid receiving end. The patient-side and fill-side pressure measuring sensors are adapted for measuring pressure in the fill line at the respective ends thereof. The device also includes a controller configured to regulate a rate of flow in the fill line responsively to a signal from the at least the patient-side pressure measuring sensor.

摘要： A tube clamp closes a flexible tube by applying a pinching force to walls of the flexible tube. The clamp includes a housing connected to a circular flange, the circular flange including a tubular wall surrounding a central bore and including at least one slot in the tubular wall sized to accept the flexible tube. A pinching element is positioned inside the central bore and is rotatable about a central axis of the circular flange. The pinching element includes a pinching projection that has a cross-sectional shape bound by a partial circle, and the partial circle has a radius substantially same as an inner radius of the tubular wall.

摘要： A patient's body temperature measurement may be made by varying the heat transfer dynamics of a fluid exiting the patient's body and fitting parameters of heat transfer configuration to measurements under the varied conditions. Then the input temperature of the patient core can be extracted from the model and a current temperature measurement remote from the patient core and optionally other measurements such as fluid flow rate.

摘要： A fluid preparation system has a sealed sterilized fluid circuit with a sealed sterilized container with a conductivity sensor in communication with an interior of said container. Further, at least one sealed connector is adapted for adding fluid to said container, and at least one sealed connector is adapted for removing fluid from said container. The conductivity sensor is contained in a test line in communication with said interior and is adapted to be connected to a source of suction thereby to draw a sample of contents of said container. Furthermore, the test line may have a check valve to prevent ingress of contaminants into said container, and the sealed connector is adapted for adding fluid to said container and may have an inline sterile filter. Furthermore, the system may have a controller that controls pumping actuators.

摘要： A fluid purification system has cells whose purifying capability can be regenerated. Some of the cells are arranged in series to reach a high level of purification. An automatic valve network is controlled to cycle the cells in a way that levels the loads on each, thereby maximizing the service interval for replacing expired cells, enabling all of the cells to be replaced at the same time after having each contributing approximately equally to the purification load, and operated such that at any one time, at least one cell is regenerated so as to enable continuous up-time.
