Problems solved by technology

In view of the preciousness of the patient's semen and the difficulty in obtaining it, theoretically it is hoped that the semen can be frozen for future use. However, the current semen cryotubes are only suitable for freezing a large amount of semen with a volume of more than 200ul, and there is no freezing of a small amount of semen. device
For patients with azoospermia and severe oligozoospermia, it is very difficult to repeatedly obtain sperm, so a micro-sperm freezing device is needed to freeze and preserve the obtained semen samples

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] As shown in the figure, the micro semen collection and storage freezing device of this embodiment includes a semen collection and storage tube 1 and a sealing tube 2 for sealing the semen collection and storage tube 1, and the semen collection and storage tube 1 includes a capillary section for absorbing semen 11 and the hand-held tube section 12 connected with the capillary section 11.

[0014] When collecting a small amount of semen, the operator holds the hand-held tube section 12, and utilizes the capillary phenomenon principle of the capillary section 11 to suck the small amount of semen into the capillary section 11. After the semen is collected in the capillary section 11, put it into the sealing tube 2 for sealed storage, which can avoid the pollution and loss of the semen, and then put the sealing tube 2 into liquid nitrogen to refrigera...

Abstract

The invention discloses a trace seminal fluid collecting, storing and freezing device for solving the difficult problem of freezing storage of trace seminal fluid obtained after a male patient with azoospermia or oligospermia is treated in an operation and a lab. The device comprises a seminal fluid collecting and storing tube and a sealing tube used for sealing the seminal fluid collecting and storing tube, wherein the seminal fluid collecting and storing tube comprises a capillary tube section used for sucking seminal fluid and a handheld tube section connected with the capillary tube section. According to the device, the trace seminal fluid is sucked by utilizing the capillarity phenomenon principle of the capillarity tube section and stored in the capillarity tube section, so that the trace seminal fluid is collected and stored; the seminal fluid collecting and storing tube is sealed with the sealing tube, so that the seminal fluid can be prevented from being polluted and lost; and the device is put in liquid nitrogen for freezing the seminal fluid, so that the trace seminal fluid is frozen for storage.

Description

technical field [0001] The invention relates to a semen collecting and storing freezing device, in particular to a trace semen collecting and storing freezing device. Background technique [0002] In the assisted cycle of human intracytoplasmic sperm injection, the volume of semen obtained from male patients with azoospermia and severe oligospermia through masturbation or surgery is less than 50ul after laboratory treatment. In view of the preciousness of the patient's semen and the difficulty in obtaining it, theoretically it is hoped that the semen can be frozen for future use. However, the current semen cryotubes are only suitable for freezing a large amount of semen with a volume of more than 200ul, and there is no freezing of a small amount of semen. device. However, it is very difficult to obtain sperm repeatedly for patients with azoospermia and severe oligozoospermia. Therefore, a micro-sperm freezing device is needed to cryopreserve the obtained semen samples. Co...
