Problems solved by technology

However, in the process of egg retrieval, due to various factors, the patient’s follicles do not grow well, there are too few mature follicles, and the condition of empty follicles will greatly reduce the quantity and quality of the eggs finally obtained. It flows down with the follicular fluid and attaches to the ovarian tissue, causing certain difficulties for egg retrieval. In addition, in the operation process of most reproductive centers, it is necessary for patient protection, process control, medical staff needlestick injury protection, negative pressure device protection and aspiration fluid. There are still many deficiencies and deficiencies in protection and other aspects

Abstract

The invention relates to the technical field of medical instruments, and discloses a push injection pressurization anti-suck-back double-cavity ovum taking needle with a puncture protection device. The ovum taking needle comprises an ovum taking needle body, a first drainage tube, a storage device and a negative pressure pump which are sequentially connected, and further comprises a flushing device which is in threaded connection with the first drainage tube, wherein the puncture protection device is arranged on the ovum taking needle body, and further, a negative pressure pump protection device is further arranged between the storage device and the negative pressure pump. According to the ovum taking needle, ovum cells attached to ovarian tissues can be well collected, the ovum cells canbe obtained as more as possible, and meanwhile, the situation that a patient is punctured by the ovum taking needle body due to improper operation can be avoided, so that the ovum taking needle is safe to use, and meanwhile the injury probability of the patient is reduced; in addition, when the ovum taking needle is not in use, a medical staff can be protected and prevented from being stabbed; andfurthermore, in the whole ovum taking process, the process can be controlled in real time, so that the situations that the negative pressure device is damaged and sucked liquid is polluted are avoided.

Description

Technical field [0001] This application relates to the technical field of medical devices, and in particular relates to a double-cavity egg retrieval needle with a puncture protection device, which is a bolus injection pressurized anti-backward suction. Background technique [0002] IVF-ET (In Vitro Fertilization-Embryo Transfer) in vitro fertilization-embryo transfer technology, also known as test tube baby, is one of the main technical means to solve infertility in contemporary medicine. It refers to the removal of eggs and sperm from the human body and In vitro fertilization, a technology that develops into an embryo and then transplants it back into the mother's womb to achieve the purpose of conception. Although the research of human in vitro fertilization-embryo transfer technology is relatively late, it has developed very rapidly. [0003] In the complete cycle of IVF-ET, the egg retrieval after the trigger has become one of the key links in the entire process, because the n...
