摘要:
In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.

This invention relates to a medical tube comprises an elongate conduit having a first opening, a second opening, a longitudinal axis, a lumen extending between the first opening and the second opening along the longitudinal axis, and a corrugated wall, formed from an extruded material, extending between the first opening and the second opening and surrounding the lumen. The wall is stiffer in a first length of the conduit adjacent the first opening than in a second length of the conduit adjacent the second opening. The variable stiffness of the tube wall can improve the thermal profile of the tube as well as improve drain-back of condensation into a humidifier providing humidified gas to the tube.
摘要:
A patient ventilating (23) and aspirating system (8) is disclosed that has a suction tube (9) and connector (6) for connecting to a catheter mount that has a scaled passageway (15). The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount.
摘要:
A circuit assembly (123) configured to provide a pneumatic path from at least a humidification chamber (104) to a patient interface (128), the circuit assembly (123) comprising two or more components, each said component including one or more heater wires (138) located therein to reduce condensation, wherein: the two or more components comprise at least an inspiratory conduit (120) and a patient supply conduit (126); at least one of the one or more heater wires (138) extends along at least a portion or an entire length of the inspiratory conduit (120); at least one of the one or more heater wires (138) is configured to heat at least a portion or an entire length of the patient supply conduit (126); and the patient supply conduit (126) is arranged proximal to the patient interface (128) and is directly or indirectly connectable to the inspiratory conduit (120).
摘要:
A catheter mount for a patient ventilating (23) and aspirating system (8) is disclosed. The a patient ventilating and aspirating system has a suction tube (9) and connector (6) for connecting to the catheter mount that has a sealed passageway (15). The catheter mount passageway is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube. When the connector is attached to the catheter mount the piercing member (20) pierces the seal such that the suction tube can pass through the connector and catheter mount. The seal includes a re-sealing mechanism configured to re-seal the seal when the aspirating system has been removed, and provides a substantially airtight seal at normal operating pressures.
摘要:
Condensation or "rain-out" is a problem in medical circuits and previous attempts to manage and/or prevent rain-out have resulted in relatively expensive and/or difficult to manufacture medical circuit components. The subject patent provides an improved medical circuit component for managing rain-out. In particular the component may be an improved breathing tube, or insufflation system limb comprising a helically corrugated tube (1) preferably incorporating a heater wire (2, 7).

Mask assemblies, breathing circuits and related components include configurations for reducing condensation within the mask and/or inhibiting or preventing condensation from coming into contact with a user of the mask. The mask assemblies can incorporate heating elements (such as heating coils), insulating spaces or barrier layers.
