Safe catheter

Abstract

The invention relates to the field of medical devices, especially a safe catheter, including a catheter body, a ventilating channel, a first balloon, and a second balloon. At that inn side of the urethral catheter, the first balloon is sleeved on the outer side of one end of the catheter body, the first balloon communicates with the ventilation channel, the other end of the catheter body is provided with an inflation joint, the other end of the ventilation channel is connected with an inflation joint, the second balloon is sleeved on the outside of the inflatable joint, A first through hole isarranged on the inflating joint, the first through hole connecting the inflation joint to the second balloon, one end of the catheter body close to the first balloon is provided with a second throughhole, The ventilation channel is provided with a scale, and the invention can enable the medical staff to observe the exposed condition of the catheter and whether the first balloon is broken in timewhen nursing the patient, so as to reduce the adverse events caused by the inability to judge the condition of the catheter in time by the scale and the second balloon.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a safety catheter. Background technique [0002] In clinical work, catheterization has become an essential operation technique, and adverse events caused by catheterization also occur from time to time. Urethral injury and catheter prolapse accounted for the majority of these adverse events. The catheters currently used in clinical practice are all without scale display. After the catheter is inserted, the medical staff cannot accurately record the exposed length of the catheter and the length of the insertion, which leads to a part of the catheter prolapse, but there is no The prolapse of the urethral opening prevents the medical staff from discovering it in time. At the same time, the balloon squeezes the urethra and catheter for a long time. Normally, the balloon is in the bladder, which causes urethral damage, and the urine cannot be discharged, which affects the doctor's fu...

AI Technical Summary

Problems solved by technology

The catheters currently used in clinical practice are all without scale display. After the catheter is inserted, the medical staff cannot accurately record the exposed length of the catheter and the length of the insertion, which leads to a part of the catheter prolapse, but there is no The prolapse of the urethral opening prevents the medical staff from discovering it in time. At the same time, the balloon squeezes the urethra and catheter for a long time. Normally, the balloon is in the bladder, which causes urethral damage, and the urine cannot be discharged, which affects the doctor's further treatment and also many complications to patients

[0003] In addition, another factor for urinary catheter prolapse is the rupture of the balloon. The current urinary catheter only has one balloon, and the catheter is inserted in. The balloon cannot be seen from the outside. Once the balloon ruptures, the medical staff If the staff cannot find out in time, urine extravasation and catheter prolapse will occur.
