SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems in the prior art and provide a stay-supported catheter.
A stay-supported catheter comprises a catheter body, an inflation tube, a first branch tube, a second branch tube, a first branch tube plug and a second branch tube plug, wherein the inflation tube is arranged on the catheter body;
the catheter main body is provided with an air bag and a cavity, the air bag is symmetrically arranged on two sides of the catheter main body, and the cavity is respectively communicated with an inflation tube, a first branch tube and a second branch tube;
the inner wall of the air bag is respectively provided with a first traction line and a second traction line, the first traction line is connected with the first branch pipe plug after passing through the cavity and the first branch pipe cavity, and the second traction line is connected with the second branch pipe plug after passing through the cavity and the second branch pipe cavity;
and an inflation inlet is arranged at the tail part of the inflation tube.
The utility model discloses a theory of operation and process:
when in use, a medical staff firstly takes out the catheter and inserts the catheter into the bladder along the urethra, then the syringe inflates the cavity of the catheter main body through the inflation port arranged at the tail part of the inflation tube, the air bags arranged at the two sides of the catheter main body are inflated under the action of air pressure, the catheter is fixed and can conduct normal catheterization, the first branch tube plug and the second branch tube plug arranged at the tail part of the first branch tube and the second branch tube can completely seal the tail part of the first branch tube and the second branch tube, the air can not overflow, when the catheter needs to be pulled out, the medical staff pulls out the first branch tube plug and the second branch tube plug, the air in the air bags is discharged by the first branch tube and the second branch tube, the first branch tube plug and the second branch tube plug are pulled by one hand of the medical staff, the first pull wire and the second pull wire arranged on the first branch tube plug and the second branch tube plug also move along with the first branch tube plug and the second branch tube plug, the other end that first tractive line and second tractive line are connected with the inner wall of gasbag, and the gasbag contracts to the cavity under the effect that first tractive line and second tractive line, has reduced the gasbag because the fold that produces exceeds the catheter outer wall of deformation, then medical personnel pull the catheter main part, pull out the catheter from patient's urethra, accomplish the work of pulling out of catheter.
The utility model has the advantages that:
the utility model has the advantages of being simple in structure and convenient in operation, safe and reliable, medical personnel can extract the operation to the catheter under the condition that does not have corresponding instrument of bleeding, and the fold that avoids gasbag deformation to produce causes the secondary injury to the urethra, has alleviateed medical personnel's the operation degree of difficulty, has saved medical resources, has also improved patient's comfort level simultaneously, and patient's psychology and health can resume fast.
