The utility model discloses a kind of gastric cavity plugging catheters of gastrostomy in the medical instrument technical field, the device increases plugging balloon and sealing clamping piece, can be held by inside and outside, hold stomach wall and skin to position the device, while plugging balloon seals and isolates the puncture of stomach wall inside gastric cavity, effectively avoid gastric juice to flow out, avoid gastric juice to overflow along the puncture and cause skin burning;Positioning baffle is also increased, can be unfolded inside duodenum, positioning baffle can position nutrition tube, avoid nutrition tube to slide and separate, can also effectively block pylorus, effectively avoid enteric digestive juice to enter stomach, and do not hinder gastric juice to flow into intestine normally, and by pressure relief port and pressure relief pipe, stomach is conveniently decompressed, effectively avoid that pressure is too high and nutrition liquid is refluxed to esophagus.

A balloon catheter includes an outer tube that has an inner surface and an inflation lumen and an inner tube that is disposed within the inflation lumen. The balloon catheter also includes a collar that has a proximal end coupled to a distal end of the outer tube, and a distal end. The collar is coupled to an edge of the distal end or the inner surface of the outer tube. The balloon catheter further includes a luminal space, which is defined by a space between the outer surface of the inner tube and the collar, and a balloon. The balloon has a proximal end coupled to the collar and a distal end coupled to the inner tube.

The utility model relates to a kind of bronchus blocking catheter of anti-displacement blockage, the top end of the blocking catheter movably connects with the fixed strip for sealing and tightening cover tight component to blocking catheter;The clamping device includes the clamping component for clamping and fixing bronchus in cover tight device, and the driving component for driving two clamping components to move in opposite directions is arranged in cover tight device. By cover cap insertion to the top end of blocking catheter, then by two rotating fixed strip is clamped in clamping strip, cover cap can be covered and tightened, three elastic strips can be used to clamp and fix bronchus, then by hand wheel driving bidirectional screw rod is rotated, two threaded sleeve plates can be made along the two threaded portions on the rod body of bidirectional screw rod to bronchus close, while fixed sleeve plate can move along guide rod, and bronchus is clamped and fixed, to prevent bronchus from the risk of loosening and falling.
