The disadvantage of this method is: the urine volume is not easy to control, if the patient’s bladder is full and there is a lot of urine, the urine will easily overflow the sterile cup when the catheter is loosened; if the urine is too little or the location is not good, the drainage will not produce urine The liquid cannot meet the requirements of rapid acquisition and volume of specimens

Embodiment 1
[0034] Example 1, an automatic urine collection device for sterile urine culture, when in use, first remove the cover plate 5 and then take out the liquid inlet connecting pipe 2, the pressure regulating connecting pipe 3 and the pressure regulating structure 4, and put the inlet The liquid connecting pipe 2 and the pressure regulating connecting pipe 3 are respectively installed corresponding to the fixing hole 11 and the connecting hole 12. Firstly, the adjustment cap 16 is adjusted to seal the inside of the liquid inlet connecting pipe 2, and then the pressure regulating connecting pipe 3 is connected with the pressure regulating structure 4, and the position of the nut 23 is adjusted so that the opening 27 is between the sealing ring 28 and the nut 23, and then the piston outer tube 21 is reciprocated, so that the gas inside the tank 1 First enter the inside of the piston outer tube 21, and then discharge from the inside of the piston outer tube 21, thereby making the insid...

The invention discloses an automatic urine collection device for sterile urine cultivation, which comprises a tank body, the inside of the tank body is detachably connected with a liquid inlet connection pipe and a pressure regulation connection pipe, and the pressure regulation connection pipe is detachably connected with a pressure regulation structure. The top of the tank is detachably connected with a cover plate. By adjusting the position of the nut, the opening is between the sealing ring and the nut, and then the outer tube of the piston is reciprocated, so that the inside of the tank can be adjusted. The gas is extracted, so that the inside of the tank forms a negative pressure environment, which facilitates the extraction of the required solution; by adjusting the position of the nut, the opening is between the sealing ring and the fixed ring, thus The blocking ball 1 can be pulled out from the inside of the retaining ring 1 through the rope 2, so that the outside air can enter the tank along the direction of the opening, the piston outer tube, the installation ring 1, the retaining ring 1, the inner pipe, and the pressure regulating connecting pipe. The inside of the tank, thereby increasing the air pressure inside the tank.
Description
technical field [0001] The invention relates to the technical field of sterile liquid collection, in particular to an automatic urine collection device for sterile urine cultivation. Background technique [0002] At present, there are two main ways to collect urine from patients with urinary catheters for sterile urine culture: one is to sterilize the proximal (patient-side) urinary catheter, puncture the urine with a 5ML syringe needle, and then inject the urine into a sterile urine cup. The disadvantage of this method is that there are many steps in the process and many consumables, and it is easy to pollute the urine and cause false positives; and as the number of punctures increases, the possibility of urinary catheter damage and leakage increases. The second is to separate the urinary catheter and the urine bag interface, and drain the urine of the urinary catheter into the urine cup. The disadvantage of this method is: the urine volume is not easy to control, if the p...
