Visual adjustable steering air sac catheter

Abstract

The invention provides a visual adjustable steering air sac catheter. The visual adjustable steering air sac catheter comprises an air sac catheter, wherein a pull wire channel is formed in the catheter of the air sac catheter; a visual system can be inserted into a urine channel of the air sac catheter, or the visual channel is arranged in the catheter; the outer opening of the visual channel isformed in the non-insertion part of the catheter, and the inner opening of the visual channel is arranged at the insertion part of the catheter; a transparent window is arranged at the catheter corresponding to the inner opening of the visual channel; the visual system is inserted into the visual channel and is used for enabling an operator to observe the intubation process in real time; and the insertion part of the catheter is also provided with a bending steering area, the hardness of the catheter of the bending steering area is smaller than that of other positions of the catheter, the bending steering area is distributed on the insertion part of the catheter along the circumferential direction, a pull wire is fixed at a pre-selected position of the bending steering area, the pull wirepenetrates through the pull wire channel, and the outer opening of the pull wire channel is arranged at the non-insertion part of the catheter. According to the air sac catheter, misinsertion of the catheter can be avoided as far as possible, and the direction of the insertion end of the catheter can be changed appropriately.

Description

technical field [0001] The invention relates to the technical field of urinary catheters, in particular to a visually adjustable steering balloon urinary catheter. Background technique [0002] In clinical work, patients often need to insert a urinary catheter. Such as: patients with various urinary retention, before surgery, bedridden due to various diseases, etc. However, the current catheter insertion methods are all blind insertion. Whether the urinary catheter enters the bladder depends on whether there is urine outflow or not, and on the basis of experience. The insertion of the urinary catheter may seem simple, but it often causes clinical problems such as hematuria, urethral injury, and catheter failure. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention proposes a visually adjustable steering balloon catheter, so as to avoid the occurrence of wrong insertion of the catheter as much as possible and shorten t...
