Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a neonate stays to get special urethral catheter of urine cultivation, including catheter body 1, catheter body 1 is inside including main duct 2, and 2 upper ends of main duct reserve and have circular mouth of pipe 3, inlet 4 has been seted up to 2 upper ends of main duct, and main duct 2 outside has seted up side opening 5, side opening 5 communicates with 2 inside each other of main duct, 2 outside fixedly connected with scale marks 6 of main duct, and scale marks 6 are located 5 both sides of side opening, 2 rear end fixedly connected with liquid taking tube 7 of main duct, and 7 outside fixedly connected with syringe joints 8 of liquid taking tube, 8 rear ends of syringe joints reserve and have liquid taking port 9, liquid-discharging port 10 has been seted up to 2 rear ends of main duct.

Furthermore, the main catheter 2 is made of transparent silica gel, the length of the main catheter 2 is 15cm, the outer diameter of the main catheter 2mm and the inner diameter of the main catheter 2mm are 1.5mm, and workers can directly observe the properties of urine through the main catheter 2, so that emergency treatment is facilitated, and irritation to the urethra of a newborn can be reduced;

furthermore, the circular pipe orifice 3 is of a smooth structure on the outer surface, and the circular pipe orifice 3 is overlapped with the vertical center line of the main catheter 2, so that the injury to the urethra of the newborn baby when the circular pipe orifice 3 is inserted into the urethra can be reduced;

furthermore, two groups of side holes 5 are symmetrically arranged about the vertical central line of the main catheter 2, the side holes 5 are of a smooth opening structure, the side holes 5 prevent the secretion of the urethral orifice from blocking the main catheter 2, and the urine can be discharged from the side holes 5;

furthermore, two groups of scale marks 6 are arranged on the outer side of the main catheter 2, the minimum scale of the scale marks 6 is 1mm, and the scale marks 6 can help an operator to observe the insertion depth of the main catheter 2 and prevent the neonate from being injured due to the fact that the main catheter is inserted too deeply;

further, the length of the liquid taking pipe 7 is 1cm, the injector joint 8 at the rear end of the liquid taking pipe 7 is made of PVC plastic, the injector can be connected into the injector joint 8 to suck the urine in the main catheter 2 through the liquid taking pipe 7, and the urine is conveniently extracted and checked.

The working principle is as follows: firstly, disinfecting skin around a urethral orifice of a newborn, laying an aseptic towel with aseptic gloves, lubricating a round pipe orifice 3 with aseptic paraffin oil, then connecting an injector joint 8 at the rear end of a liquid taking pipe 7 with an aseptic injector, inserting a main catheter 2 into the urethral orifice of the newborn until urine is discharged, observing the urine property of the newborn because the main catheter 2 is made of transparent silica gel, immediately stopping operation when the urethral orifice is damaged, then observing the inserting depth of the main catheter 2 through a scale mark 6 on the outer side of the main catheter 2, generally, the inserting depth of a male infant is 5-8cm, the inserting depth of a female infant is 3-6cm, if a liquid inlet 4 is blocked by secretion of the urethral orifice, the urine can be discharged into the main catheter 2 from a side hole 5, successfully placing the main catheter 2 into a back hand to fix a catheter body 1, and taking out the aseptic injector by one hand, the required amount of urine specimen is left, and then the main catheter 2 is pulled out.
