Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a urine collection device through catheter. BACKGROUND

[0002] The urine collection device is a device for collecting urine samples in a catheter, such as the urine segment collection device provided in application No. 202221209981.7, which includes a catheter funnel, a catheter, and a urine collection bag. The catheter funnel is in communication with the urine collection bag through the catheter. The urine collection bag is at least two. The liquid inlet end of each catheter is provided with a first sealing clamp for sealing the catheter and the urine collection bag. In the initial state, the first sealing clamp on each catheter is in a clamping state to seal the liquid inlet end of the catheter. When using, the operator can make the urine in the catheter funnel enter the urine collection bag by opening the first sealing clamp on the catheter. When the urine in the urine collection bag reaches the liquid volume, the first sealing clamp on the current catheter is clamped, and the first sealing clamp on the next catheter is opened, thereby completing the segmented collection of urine. The utility model facilitates the operator to collect urine independently, such as the segmented collection of the front, middle, and rear segments of urine, thereby improving the accuracy of urine detection, and has the advantages of simple operation, simple structure, low cost, etc.
