Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a midstream urine collection device. Background Art

[0002] Urinalysis is one of the most common examination items in hospitals. When conducting a routine urine test, hospitals usually provide patients with a urine cup and a sampling tube. Patients are required to operate in the bathroom by themselves. Patients need to manually collect urine with the urine cup and then introduce the urine collected in the urine cup into the sampling tube to complete the sampling.

[0003] The invention patent with patent number CN117918900B discloses a urine sampling device for laboratory, which belongs to the field of medical device technology, including a toilet, a segmented urine collection pipe, a mid-stream urine storage bin and a sampling tube. A connecting pipe is provided on one side of the toilet, the segmented urine collection pipe passes through the connecting pipe and is inserted on the toilet, the mid-stream urine storage bin is arranged at one end of the connecting pipe, the connecting pipe connects the toilet and the mid-stream urine storage bin, and the sampling tube is inserted in the mid-stream urine storage bin; the mid-stream urine is automatically separated into the mid-stream urine storage bin through the segmented urine collection pipe, which is convenient for patients to accurately extract mid-stream urine, solving the problems of unsanitary urine sampling technology and unprofessional sampling by non-professional patients and medical staff.

[0004] However, the invention patent has the following shortcomings:

[0005] (1) When the patient is urinating, the first-pass urine passes through the urine collecting funnel and the segmented urine collection tube into the first-pass urine filter section. The first-pass urine is collected and discharged, and then the mid-pass urine is collected directly. Although the first-pass urine is discharged, the urine collecting funnel, the segmented urine collection tube and the inner wall of the first-pass urine filter section are all stained with the first-pass urine. Collecting the mid-pass urine directly will cause the collected mid-pass urine to be mixed with part of the first-pass urine, resulting in sample contamination.

[0006] (2) The water-absorbing resin absorbs water and expands, pushing the circular plate to push the valve stem upward, thereby realizing the subsequent functions. However, the water-absorbing resin will become a gel when it absorbs water and cannot recover on its own. That is, the circular plate, valve stem and other parts cannot be reset, which makes the device unable to be reused. Summary of the invention
