Description

Safe type urine is cultivateed and is left and get window

Technical Field

The utility model relates to the technical field of medical treatment, specifically be a safe type urine is cultivateed and is stayed window.

Background

Urine culture refers to the culture of bacteria in normal urine. Normal urine is sterile liquid, but various bacteria exist on the external surface of the urogenital tract of a human body, and because the pH is acidic, pathogenic bacteria do not exist in the vagina of a female, and a plurality of conditional pathogenic bacteria such as lactobacillus are parasitized. With the change in pH, the normal flora will also change. Therefore, the urine culture should be performed by aseptically taking the urine (preferably, under the guidance of doctors, cleaning and disinfecting the external urethra), eliminating the interference of external bacteria, and accurately detecting whether the urine has bacteria, pathogenic bacteria or conditional pathogenic bacteria.

Application number is CN201920917002.5, the name is a can directly stay utility model patent of getting the catheter of urine culture sample, including the catheter, be equipped with the auxiliary sampling subassembly on the catheter, the auxiliary sampling subassembly includes heparin cap pad and protecting crust, heparin cap pad and protecting crust all are the arc setting, and heparin cap pad and protecting crust be connected with the both sides fixed surface of catheter respectively, the position of heparin cap pad and protecting crust is the symmetry setting, be equipped with the fastener main part on the catheter, the fastener main part is located the low reaches of auxiliary sampling subassembly. The utility model discloses a through setting up heparin cap pad and protecting crust symmetry in the catheter both sides, when needs sample, can utilize the blood sampling syringe needle to pass during the heparin cap pad pierces the ureter perpendicularly, extract after the sufficient urine pull out the needle can, the heparin cap pad can puncture repeatedly, can not take place the leakage phenomenon, and the protecting crust can avoid the catheter opposite side to be impaled, sample easy operation can avoid infecting because of the chance that separation ureter and drainage urine bag caused.

However, the ordinary urine culture collection window is punctured by a syringe with a needle to collect a specimen, which easily causes the puncture injury of medical staff, the sharp needle point easily penetrates through the tube wall when penetrating through the ordinary sampling window to cause the damage of the drainage bag pipeline, and the window is easy to leak urine after being punctured for many times. The catheter is arranged at a position close to the body weight of a patient, and psychological panic of the patient is easily caused by holding a needle for sampling, so that a safe urine culture indwelling window is designed.
