A bladder positioning catheterization device for caesarean section

Abstract

The invention provides a bladder positioning catheterization device for cesarean section, which comprises an insertion tube made of medical rubber, a lighting optical fiber is arranged in the center of the insertion tube, and infusion holes and catheterization holes are arranged on both sides of the insertion tube; The front end of the head is provided with a spiral lighting head, and the rear end of the lighting fiber is provided with a fiber optic light source; the center of the spiral lighting head is provided with a buffer cap made of medical rubber; the rear end of the infusion hole is connected with a cleaning and sterilization device through a one-way infusion valve , the back end of the urinary catheter is connected with a measuring recovery device through a one-way infusion valve and a liquid discharge switch; a sealing plug is sleeved in the middle of the insertion tube, and C-shaped elastic positioning belts are respectively arranged on both sides of the back end of the sealing plug. The beneficial effect of the present invention: during cesarean section, bladder damage can be effectively avoided, urinary catheterization can be performed well, the normal contractility of the bladder can be assisted to be restored, and postpartum urinary retention can be reduced or eliminated.

Description

technical field [0001] The invention relates to the technical field of cesarean section auxiliary tools, in particular to a bladder positioning catheterization device for cesarean section. Background technique [0002] In order to solve problems such as high-risk pregnancy, dystocia, and one-child delivery by cesarean section, cesarean section is generally used in obstetrics. Cesarean section is an important method of surgical midwifery. During the delivery process, the fetus cannot be delivered naturally due to maternal or fetal reasons, and the doctor adopts a process of transabdominal incision of the uterus to remove the fetus and its appendages. . However, due to the presence of a large amount of blood after abdominal incision, the line of sight is greatly affected, and the distance between the uterus and the bladder is too close. Doctors can only judge the position of the bladder and uterus based on experience. The midwifery doctor increases the difficulty of the work...

Problems solved by technology

However, due to the presence of a large amount of blood after abdominal incision, the line of sight is greatly affected, and the distance between the uterus and the bladder is too close. Doctors can only judge the positions of the bladder and uterus based on experience. The midwifery doctor increases the difficulty of the work; in the cesarean section, the puerpera often affects the autonomous urination function due to anesthesia, which will cause the bladder to expand and the uterus to be unable to contract quickly in a short period of time, thus causing massive postpartum hemorrhage , so that the puerpera is in danger, so obstetrics often use catheters to solve the above problems. Although it can solve the problem of catheterization, the currently commonly used catheter is a balloon catheter, and the front end of the catheter is inserted into the bladder. It is necessary to inject liquid or gas into the air bag to inflate the air bag to prevent the prolapse of the catheter, but the inflated air bag increases the pressure on the inner side of the bladder, which cannot well eliminate the internal pressure of the bladder and ensure the normal contraction of the uterus. After cesarean section, it is often necessary to indwell the urinary catheter for a period of time, but extubation is often accompanied by problems such as pain, infection, and difficulty in urinating on its own
