The aluminum strip is stored between the outer-layer glass body and the inner-layer glass body and inside the sealing adhesive piece. The outer-layer glass body and the inner-layer glass body are connected through the adhesive piece in a sealed mode. According to the sealing double-layer heat reflection hollow glass, metal-plating oxide thin film mirror glass is adopted so that infrared rays can be better reflected; a drying agent is stored in the hollow aluminum strip, so that the large humidity caused due to the fact that the inner and outer temperatures of the double-layer glass are not even is prevented, and a better heat insulation effect is achieved; through the adhesive piece, uneven distribution of traditional glue is solved; and through an outermost sealing protecting bush, airtightness of the double-layer glass is further improved, and the most fragile corners of the double-layer glass are protected.

Self-control pulse irrigating tube
InactiveCN102553012AEasy to rinseIrrigate Fluid FilledStentsBalloon catheterCause blockageEngineering
The invention relates to a medical irrigating tube, in particular to a self-control pulse irrigating tube, which comprises a drainage tube. A filling-end pluggable joint and a drainage-end pluggable joint are respectively mounted at two ends of the drainage tube through adjustable valves, side through holes spirally arranged on the wall of the drainage tube, an elastic balloon is connected to thefilling-end pluggable joint in series, and the diameters of the side through holes are reduced sequentially from the filling-end pluggable joint to the drainage-end pluggable joint. Compared with theprior art, the self-control pulse irrigating tube has the advantages that high negative pressure is formed in the irrigating tube by the elastic balloon within a short time and irrigates blood clots or fall-off tissues which are attached to block the side through holes of the drainage tube under the negative pressure action; since the diameters of the side through holes are reduced sequentially from the filling-end pluggable joint to the drainage-end pluggable joint, irrigation solution is easy to flow to a focus region due to the fact that the side through holes close to the filling end are larger, and larger blood clots and necrotic fall-off tissue are not easy to be sucked to cause blockage due to the fact that the side through holes close to the drainage end are smaller when the irrigating tube is used for irrigating under normal pressure.
