Problems solved by technology

The processed semen needs to be transferred into cryogenic tubes or straws through a pipette. The operation is complicated, and it is easy to waste a small amount of semen. For patients with azoospermia and severe oligospermia, sperm are very precious and cannot be wasted. Therefore, there is a need for a one-time freezing device for absorbing and storing a small amount of semen for later ICSI operations

Abstract

The invention relates to a male infertility seminal fluid extraction and storage device, which comprises a straw and a protection cover, wherein an injection device is arranged on one end of the straw; an end cap is arranged on the other end of the straw; the protection cover is arranged outside the straw; one end of the protection cover sleeves the injection device; the other end of the protection cover sleeves the end cap. According to the male infertility sperm extraction and storage device provided by the invention, during quick freezing and unfreezing processes, a positioning rod and theend cap are prevented from shifting, so that the straw is ensured to be in a sealed state in the freezing and unfreezing processes; the protection cover protects the straw against being acted by an external force, and meanwhile, the straw can be conveniently found; trace of seminal fluid can be sucked up through unscrewing the positioning rod, slowly pulling an air cushion and increasing a space in a cylinder, and is stored in the straw; when the seminal fluid is used, the positioning rod is screwed in and compresses air in the cylinder so as to push the trace of seminal fluid out of the straw, so that the trace of seminal fluid can be applied to other operations, sucked up, stored and unfrozen.

Description

technical field [0001] The invention relates to the field of semen preservation, in particular to a device for extracting and preserving male infertile semen. Background technique [0002] Men account for 30-40% of the causes of infertility, and azoospermia and oligospermia account for about 10%. In 1992, life insurance companies such as Palermo introduced the intracytoplasmic sperm microinjection technology to solve the problem of severe male infertility, weakness, and The problem of infertility in patients with teratospermia. However, ICSI technology combined with microscopic shell sperm extraction such as epididymis sperm aspiration, percutaneous epididymis puncture sperm extraction and testicular sperm extraction, it is possible for azoospermic patients to raise genetic offspring. [0003] However, the semen obtained through masturbation or surgery is processed in the laboratory, and then subjected to vitrification technology. Using a small-sized cryo-carrying tool, the...
