Description

Single J pigtail type pipe

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a single J pigtail type pipe.

Background

A pigtail catheter (also called a ureteral stent) is a long and thin flexible tube which is used for retention in a ureter of a human body in the treatment of urinary obstruction and other diseases caused by renal calculus, ureteral calculus, kidney transplantation, hydronephrosis, and ureteral stenosis due to various causes (inflammatory stenosis and postradiotherapy stenosis), because the end of the pigtail catheter is curled and the end of the pigtail catheter is shaped like a pigtail. The postoperative management of a patient who uses the drainage in the pigtail catheter tends to be simplified, the patient can move in an early stage due to the built-in catheter, the infection chance is reduced, the nursing workload is obviously reduced, the postoperative recovery of the patient is fast, and the hospitalization time is obviously shortened. According to different duct types, the duct is divided into a double J-shaped pigtail duct and a single J-shaped pigtail duct. The double J-shaped pigtail catheter is named because the two ends are curled and the tail end is shaped like a pigtail. The ureteral stent tube is kept in a ureter of a patient and is used for supporting the ureter, one end of the ureteral stent tube is arranged in the kidney of the patient, the other end of the ureteral stent tube is arranged in the bladder of the patient, and urine in the kidney and postoperative small crushed stones are drained into the bladder. The ureteral stent tube is made of soft materials when being left in the ureter, can reduce the stimulation to the ureter and the bladder, has the retention time of less than three months generally, relieves the pain of patients caused by diseases and reduces the risks of postoperative ureteral stenosis and secondary kidney stone. Because of the functions of stent and internal drainage, the temporary obstruction caused by ureter inflammation and edema can be relieved, and the leakage of urine from wounds and ureter stenosis after operation can be prevented. Meanwhile, the whole system is not directly communicated with the outside, so that bleeding and infection caused by nephrostomy can be avoided; because of no restriction and uncomfortable feeling of the external drainage tube, the patient can get out of bed for activity in early stage, which is beneficial to postoperative rehabilitation. The single J-shaped pigtail catheter is commonly used for complicated urinary tract operation and plays roles in supporting and draining. In the prior art, a single J-shaped pigtail catheter is only provided with a curl similar to a pigtail at one end, the curled end is arranged in the kidney of a patient, the other end of the single J-shaped pigtail catheter is provided with a horn joint and leads the outside of the patient, and the horn joint is connected with a urine collection bag provided with a conical head. The defect is that the common horn joint is made of PVC material, the horn joint is connected with the conical head of the urine collecting bag in an inserting way, the single J-shaped pigtail catheter is made of polyurethane material, and glue is needed for bonding in order to facilitate the connection of the single J-shaped pigtail catheter and the horn joint. The hardness of the horn joint made of PVC material is hard, when the horn joint is connected with the conical head, the sealing effect is not ideal, the horn joint is easy to deform when being extruded, and the liquid leakage phenomenon is easy to occur when the horn joint is not tightly sealed. The single J-shaped pigtail catheter needs to be kept in a human body for a long time, and a horn joint outside the body of a patient is easily extruded and is not tightly sealed with a cone joint, so that the liquid leakage phenomenon is generated.
