Description

TECHNICAL FIELD

[0001] The utility model relates to a semen quantitative collection device belongs to medical supplies technical field. BACKGROUND

[0002] In the World Health Organization's "Human Semen Examination and Processing Laboratory Handbook", an important indicator for evaluating male reproductive capacity is the total number of sperm discharged per ejaculation and the total number of motile sperm discharged per ejaculation. The total number of sperm per ejaculation is more diagnostic than sperm concentration, but the prerequisite is to accurately measure the semen volume. Semen volume provides information related to the function of accessory glands, therefore, accurate measurement of semen volume is the basis for any semen evaluation. The manual stipulates that semen volume detection is not recommended to suck semen from the measuring cup to the pipette and syringe or pour into the measuring cylinder to measure the volume, because the lost volume can be between 0.3 to 0.9 milliliters.

[0003] Currently, the commonly used semen collection device is, for example, the quantitative semen transfer device that simultaneously realizes the collection, lysis and sample adding three steps as shown in CN205642913U. The structure of this device is a needle cylinder type, although it meets the quantitative drop adding, it cannot be directly connected to the collection site, and the process of semen transfer will occur, therefore, it cannot solve the leakage problem in the transfer process. In addition, for example, a semen collection device for urology surgery as shown in CN114601540B, this device can meet the direct collection and non-destructive transfer requirements, but it cannot meet the function of quantitative drop adding, and still needs to be transferred after the container to be able to drop and detect and difficult to control the quantity.

[0004] Therefore, the existing semen collector generally has the technical problems of insufficient semen collection, incomplete sealing after collection, volume loss caused by semen transfer process, etc. Accurate retention of complete semen specimens is the premise of semen analysis and artificial insemination treatment, and the correctness of semen specimen collection directly affects the correctness of the test results.

[0005] In addition, the current hospital semen collection container is a wide-mouth collection bottle, and the patient is easy to spill when collecting semen, the semen volume is not accurate each time, which brings difficulties to the test of total sperm count, and the waiting period for re-collection of semen for testing needs to be interval 2-7 days, which also affects the patient's diagnosis and treatment effect.
