A stent delivery catheter system having a catheter with stent releasably mounted on a stent retention portion of the catheter for delivery and deployment within a patient's body lumen, and a method of mounting the stent on the stent retention portion of the catheter. The method generally includes exposing the stent retention portion and / or the stent to a solvent, the solvent being in the vapor phase. The vapor phase solvent typically softens the stent retention portion of the catheter, and / or, in one embodiment in which the stent has a coating on the stent body, the vapor phase solvent softens the stent coating. In a presently preferred embodiment, the stent polymeric coating has a therapeutic agent, and the method of the invention prevents or inhibits disadvantageously affecting the therapeutic agent coating during mounting of the stent on the catheter.

The invention discloses a shaft sleeve structure for installing an air duct switching device. An installation groove is formed in the side wall of an air duct, a bearing sleeve with a non-circular periphery is fixedly inserted, connected and fixed in the installation groove, and an installation hole for correspondingly inserting and connecting a baffle shaft of an air duct baffle is formed in thebearing sleeve. The bearing sleeve which is detachably mounted is arranged on the side wall of the air duct, so that a bearing of an air duct reversing device can be detachably replaced, and the purposes of detachably installing and quickly assembling and replacing the bearing sleeve of the baffle shaft are achieved. The invention also discloses the air duct switching device which comprises an airduct baffle plate which is arranged on the air duct and can rotate relatively; the baffle shaft of the air duct baffle is installed in the air duct through the shaft sleeve structure; a motor outputshaft is connected with the air duct baffle through a connecting rod mechanism, so that the air duct baffle is driven to rotate around the shaft through the connecting rod mechanism in the rotating process of the motor output shaft, and the air duct baffle is switched and moved between a first position and a second position.

The invention discloses a rotary table used in a cooling and heating dual-purpose type ceiling fan. The rotary table comprises an upper disc body and a lower disc body, wherein the upper disc body andthe lower disc body are combined into a whole in the up-and-down direction. Dovetail grooves which are used for being capable of achieving assembly and disassembly of fan blades are formed in the periphery of the upper disc body in an array mode, and the lower sides of the dovetail grooves extend to the lower end face of the upper disc body. An annular groove which is connected with the upper sides of the dovetail grooves is formed in the upper disc body in the annular direction. A plurality of longitudinal through holes which are used for allowing studs to pass through are formed in the upper disc body and the lower disc body in the longitudinal direction, and the two ends, passing out of the corresponding longitudinal through hole, of each stud are connected with manual screwing nuts ina rotating mode correspondingly. The portion, stretching out of the upper end face of the upper disc body, of each stud is connected with a hexagon nut and the corresponding manual screwing nut in arotating mode, and the hexagon nuts and the manual screwing nuts are used for achieving installation of blades and locking of the upper disc body and the lower disc body. A hexagonal hole groove is formed in one end of each blade in the longitudinal direction. By the adoption of the technical scheme, the fan blades and the blades can be conveniently, reliably and detachably connected, and therefore the requirement for heating or cold air supplying can be met, the effect of the indoor ceiling fan can be made full use of, and the purpose that the dual functions of supplying cold air and supplying hot air are fulfilled by the ceiling fan is achieved through a detachable structure.

The invention discloses a built-in fuse connector which comprises a fuse base, a clamping base, a fuse, a wiring terminal and a connecting terminal, wherein the fuse base comprises a first connecting end and a second connecting end in the axis direction, a first accommodating cavity is formed in the fuse base and penetrates through the first connecting end and the second connecting end, the wiring terminal is installed in the first accommodating cavity, the clamping base comprises a first clamping end and a second clamping end in the axis direction, a second accommodating cavity is formed in the clamping base and penetrates through the first clamping end and the second clamping end, the connecting terminal is installed in the second accommodating cavity, the clamping base is clamped at the second connecting end of the fuse base, the first accommodating cavity is communicated with the second accommodating cavity, the fuse is installed in the first accommodating cavity and the second accommodating cavity, and the fuse is connected with the wiring terminal and the connecting terminal. According to thebuilt-in fuse connector, the fuse is combined with the connector, rapid replacement and installation of the fuse are achieved, and the connector is simple in structure, convenient to install and small in size and does not need to occupy a large installation space.
