3results about How to "Easy intubation" patented technology

This utility model relates to the field of hose connector technology, specifically a gas hose connector, including a connector body with a butterfly valve in the middle, prisms at both ends, a guide tube at the left end, an insertion tube at the right end, and a threaded cylinder at the left end of the connector body, fitted outside the guide tube. A limiting cap is fitted on the outer wall of the threaded cylinder. This gas hose connector features a connector body with two prisms, and a butterfly valve in the middle. The prisms provide a leverage point for easy installation with an external wrench. The butterfly valve controls the internal connection or disconnection of the connector body. A guide tube with a convex ring is installed at the left end of the connector body. The limiting cap is threadedly connected to the threaded cylinder at the left end of the connector body, achieving compression and fixation of the gas hose fitted on the outer wall of the guide tube. The convex ring and the limiting ring are staggered to increase the contact area with the outer and inner walls of the gas hose, thereby achieving stable installation and fixation.

The utility model discloses a pipe inserting device. The pipe inserting device comprises a base; the mounting seat is connected with one end of the base, the mounting seat is arranged between a mold core station and a guide pipe station, the first positioning assembly and the second positioning assembly are arranged on the mounting seat, a first through hole is formed in the first positioning assembly, the inner diameter of the first through hole is matched with the outer diameter of a mold core, and the inner diameter of the second through hole is matched with the outer diameter of the mold core. A second through hole is formed in the second positioning assembly, the second through hole and the first through hole are concentrically arranged, the minimum hole diameter of the second through hole is matched with the outer diameter of a guide pipe, and the minimum hole diameter of the second through hole is larger than the minimum hole diameter of the first through hole; the catheter clamping assembly is arranged on the base and used for clamping a catheter; the first moving assembly is used for driving the base to move in the first horizontal direction. Compared with the prior art, the pipe inserting device can improve the pipe inserting efficiency and improve the overall production efficiency.

This invention relates to a universal catheter for accessing visceral arteries via the radial artery, belonging to the field of medical device technology. The catheter is hook-shaped and comprises, on the same plane, a first straight segment, a first curved segment, a second straight segment, a second curved segment, a third straight segment, a third curved segment, and a straight head segment arranged sequentially from the end closest to the operator, with the straight head segment facing the beginning of the catheter. The specialized catheter provided by this invention increases the catheter's curvature, resulting in better stability after insertion into the target vessel; it also has better torque transmission capability, good maneuverability, and makes it easier to reach the target location within the blood vessel, shortening the operation time and increasing the success rate of the surgery.
