Imaging scope

Disclosed is an intubation imaging stylet for intubating a patient by use in a tube / imaging stylet combination, said imaging stylet comprising: a malleable stylet having a longitudinal axis and a proximal end and a distal end; a flexible image guide having a longitudinal axis and a proximal end and a distal end, said image guide being connected to said stylet such that a portion of said image guide runs parallel to a portion of said stylet along the longitudinal axis of said stylet and such that the distal end of said image guide is co-extensive with the distal end of said stylet; and at least one flexible illumination fiber having a proximal end and a distal end, said illumination fiber being connected to said stylet such that a portion of said illumination fiber runs parallel to a portion of said stylet along the longitudinal axis of said stylet and such that the distal end of said illumination fiber is co-extensive with the distal end of said stylet; such that in use, said imaging stylet is disposed within a tube for intubating a patient thereby forming an imaging stylet / tube combination which in use is held by gripping the tube in a pen-like fashion. The imaging stylet / tube combination is thus in use held in one hand, freeing the other hand of the user for other tasks if necessary, as well as permitting intubation in the conventional manner. To facilitate this, the center of gravity of the imaging stylet / tube combination is located in essentially the same location along the tube as with a conventional stylet / tube combination.

High-efficiency LED lamp bulb

The invention discloses a high-efficiency light emitting diode (LED) lamp bulb. The high-efficiency LED lamp bulb comprises a light transmitting bulb shell, a core column, at least one LED light emitting strip, a driver and an electric connector, wherein the core column is provided with an exhaust tube, an electric lead-out wire and a bracket; the LED light emitting strip is fixed on the core column, and an electrode of the LED light emitting strip is connected with the driver and the electric connector through the electric lead-out wire of the core column so as to connect an external power supply; the light transmitting bulb shell and the core column are hermetically sealed; the bulb shell is filled with gas with high heat conductivity; the LED light emitting strip comprises a transparent substrate strip which is provided with at least one strip of LED chips connected in series for emitting light of the same or different colors and is sealed in a glass tube; the electrode of the LED is led out of the two ends of the glass tube; the lead-out wire and the glass tube are hermetically sealed; the glass tube is filled with the material with high heat conductivity and high light transmittance; the LED chip emits light of 4pi; the inner or outer wall of the glass tube or the inner wall of the light transmitting bulb shell is provided with a light emitting material; and at least one LED light emitting strip is connected to form a one-way direct current DC or two-way alternating current AC to work. The LED lamp bulb of the invention has the advantages that: the LED chip emits light of 4pi, a heavy radiator is not needed, the driver does not need a transformer and the entire lamp has high efficiency, low cost, and is safe and reliable and the like, and is used for lighting.

Bead-chain driven double-glazed built-in shutters

The invention discloses a bead chain driving type double-layer hollow glass built-in louver and belongs to the technical field of sunshade hollow glass products. The louver comprises a window body, a curtain piece turning mechanism, a venetian blind, an inner control mechanism, an outer control mechanism and a venetian blind lifting traction rope. The window body comprises an upper window body transverse tube, a lower window body transverse tube, a left window body longitudinal tube, a right window body longitudinal tube, inner glass and outer glass. The louver is characterized in that the inner control mechanism comprises a box body, a box cover, a synchronous belt pulley, a synchronous belt and a lifting traction rope driving wheel. The outer control mechanism comprises a protective cover, a friction plate, a bead chain wheel shaft, a bead chain wheel shaft hub, a bead chain and a bead chain wheel shaft base. The protective cover forms a protective cover cavity. The friction plate is arranged in the protective cover cavity. The bead chain wheel shaft hub is supported by a shaft hub cavity. The bead chain wheel shaft is arranged in the middle of the bead chain wheel shaft hub. One end of the bead chain is arranged on the bead chain wheel shaft hub in a sleeving mode. The other end of the bead chain forms a suspending end. The bead chain wheel shaft base is matched with the protective cover. One end of the venetian blind lifting traction rope is in driving connection with a lifting traction rope driving wheel. Manufacturing cost is reduced; labor is saved during operation; service life is long, and the using effect is good; resource-saving economy is reflected.
