Example Embodiment

[0015] Such as figure 1 The hand-held electric egg harvesting device shown includes a gun body 17 with a manual switch 18. A negative pressure device is arranged inside the gun body 17.

[0016] Specifically, a negative pressure cylinder 15 is fixed in the handle cavity of the gun body 17, a piston 14 is matched and sleeved in the negative pressure cylinder 15, and a sliding rod 8 is connected to the piston 14, and the sliding rod 8 is arranged in the gun body 17 The slides are matched and installed together.

[0017] At the same time, an electric drive mechanism is installed at the rear end of the gun body 17, for example, the motor 11 is used to drive the gearbox 12 as the power output of the electric drive. The power source used to drive the electric drive mechanism is an external power source or a built-in power source. The built-in power source is provided with a battery box 2 at the front end of the gun body 17 and a battery 4 is installed in it.

[0018] A gear 13 is install...

Abstract

The invention discloses a handheld electric ovum sampling device which comprises a negative pressure device and an ovum sampling needle, a negative pressure cylinder is fixedly arranged in a gun body handle inner cavity of the negative device, the negative pressure cylinder is matched with a piston in a sleeved mode, the piston is connected with a slider and provided with a rack, and an output shaft of an electric driving mechanism is provided with a wheel gear which is meshed with the rack; anegative pressure tube connected with the upper cavity of the negative pressure cylinder is communicated with a storage bottle through a filter; the inner end of the ovum sampling needle is located into the storage bottle, and a manual switch powered by electricity to work is arranged. The device is simple in structure and easy to use with high efficiency, the device can be used in a laboratory and taken out to the wild, a culture medium is omitted, and it is convenient for later ovoscopy.

Description

Technical field [0001] The invention belongs to the technical field of mammalian in vitro fertilization aids, and specifically relates to a handheld electric egg collection device. Background technique [0002] Collecting oocytes from discarded ovaries is a common task in animal embryo engineering. Generally, there are two solutions: 1) Manually extract with a syringe. The method is to first suck a certain amount of culture medium in the syringe, and then pierce the needle into the follicle to collect the eggs. The advantage is low cost and it can be taken to the field to work, but the disadvantage is that the operation efficiency is low and too much culture medium will be consumed, which will bring trouble to the next egg inspection work. [0003] 2) Use negative pressure pump to extract. The method is that after the negative pressure pump is turned on, because of the continuous negative pressure, the needle can be used to continuously collect the eggs. The efficiency is higher ...
