Catheter with multiple heating/cooling fibers employing fiber spreading features

InactiveUS20010031946A1Prevent clottingCool the nearby tissue more efficientlyOther blood circulation devicesElectric heatingFiberBody fluid
A catheter using multiple hollow fibers to carry a heating/cooling fluid employs fiber spreading features to improve heat transfer and help prevent clotting of body fluids within which the catheter is immersed. The catheter includes a length of outer tube surrounding an inner tube. The inner tube conveys fluids in one direction, and the passageway between inner and outer tubes conveys fluids in the opposite direction. The inner and outer tubes have proximal distal ends. The distal end is closed, but the proximal end is open to permit introduction of a heating or cooling fluid into the inner tube, and withdrawal of the fluid from the passageway between the inner and outer tubes. At the tubes' distal end resides a proximal fluid transfer housing coupled to multiple hollow heat exchange fibers. The distal ends of these fibers may be commonly connected to a distal fluid transfer housing and optional reservoir, which cooperatively return fluid to the passageway between inner and outer tubes. In another embodiment, each fiber includes both outflowing and return lumens, enabling the fibers' distal ends to freely move about. In another embodiment, each fiber proceeds outward from the proximal fluid transfer housing, and returns back to form a loop. In each different embodiment, the invention includes one or more actuating structures to spread the fibers. The actuating structure may include, for example, fiber shaping, a retractable spreading member, elastic bias built into the fibers, etc.

Connecting head of an electronic cigarette and electronic cigarette

An electronic cigarette (100) and a connecting head (3) for an electronic cigarette are provided. The electronic cigarette (100) includes an inhalation rod (2), a battery rod (1), and a connecting head (3). The connecting head (3) of the electronic cigarette (100) makes the inhalation rod (2) and the battery rod (3) connected into an integral and formed a central airway in an internal thereof. The connecting head (3) includes an exposed step (31), a first connecting end (31) and a second connecting end (33) disposed at the two sides of the exposed step (31) respectively along a radial direction. The first connecting end (31) is used to connect with the battery rod (2) of the electronic cigarette (100), and the second connecting end (33) connects with the inhalation rod (2). A surface of the exposed step (31) disposes at least one air inlet (311). When assembling the electronic cigarette (100), the air inlet (311) is exposed on the surface of the electronic cigarette (100). When the air pressure inside the inhalation rod (2) is less than the outside air pressure, air is supplied into the internal of the inhalation rod (2) by the air inlet (311). The sensitivity of the air inlet (311) on the connecting head for sensing the ventilation volume is very high, then easy to control the ventilation volume, and then can effectively guarantee the stability of the electronic cigarette taste.
