Description

Urinary catheterization device for collecting urine test samples

Technical Field

The utility model relates to a urinary catheterization device, in particular to a urinary catheterization device which is convenient for collecting urine testing samples.

Background Art

Urine testing is a medical testing method. Before conducting a urine test, you need to collect the urine sample for testing in a clean container.

At present, when medical staff collect urine from patients with indwelling urinary catheters, they generally pull out the outlet of the catheter from the urine collection bag, disinfect the outlet of the catheter, and then extract samples from the outlet of the catheter with a syringe. When the amount of urine from the patient is too small, it is difficult to extract samples that can meet the test requirements, which can easily lead to the failure to conduct the test in a timely manner and delay the determination and diagnosis of the patient's condition. If urine is extracted from the urine collection bag, the components in the urine will be exposed to the urine for a long time due to the long-term exposure, resulting in qualitative changes and contamination, which seriously affects the accuracy of the test results. Therefore, how to collect urine samples from patients with indwelling urinary catheters in a timely manner without being contaminated by the outside world has become a long-standing technical problem that is difficult to solve.

Beneficial effects: When the utility model is used, the liquid outlet is inserted into the urine collecting bag, and the liquid outlet speed of the liquid outlet is adjusted or locked by the speed regulator, so that the amount of urine entering the Moffitt's dropper is greater than the outflow amount of the liquid outlet. When the urine retention amount in the Moffitt's dropper reaches the scale line position of the amount required for detection, the speed regulator is fully opened to keep the urine retention amount in the Moffitt's dropper at the scale position of the amount required for detection. As urine continues to enter the Moffitt's dropper, the old urine at the bottom of the Moffitt's dropper is continuously discharged from the liquid outlet, which avoids the urine being left for too long, and the components inside being exposed for a long time to cause qualitative changes and pollution. When urine needs to be taken for detection, the speed regulator is fully opened. Through the adjustment switch assembly and the speed regulator, when the switch assembly is closed, the top plate is pressed, and the hook on the top plate is clamped on one end of the bottom plate. At the same time, the pressure block at the bottom end of the pressure plate on the top plate is pressed in the arc groove to tighten the pipe passing through the through hole, thereby completing the closure. When opening, the hook is pushed away from the bottom plate to completely close the pipeline on the upper side and the pipeline on the lower side of the Moffitt dropper. The Moffitt dropper is disassembled at the threaded connector to facilitate sample delivery and detection. The threaded connector is connected to a replacement Moffitt dropper to collect urine for use in the next test; the one-way air outlet valve is used to balance the pressure in the Moffitt dropper to prevent excessive pressure in the Moffitt dropper from affecting liquid inlet.

The utility model has a novel structure and an ingenious design. The Moffitt's dropper can be disassembled at the threaded connector to facilitate sample delivery for testing. The threaded connector is connected to a replacement Moffitt's dropper to collect urine for use in the next test. The one-way air outlet valve is used to balance the pressure in the Moffitt's dropper to prevent excessive pressure in the Moffitt's dropper from affecting liquid inlet.
