Abstract

The invention relates to a novel test-tube baby ovum-peeling manipulator, and belongs to the field of manufacturing technology of an ovum peeling device. The novel test-tube baby ovum-peeling manipulator is composed of a handheld press device and an ovocyte sucking device, wherein the handheld press device is composed of a press rod cap, a pen cap, a rear shell, a spring, a press rod and a front shell, and the ovocyte sucking device is composed of an airbag, a poly styrene (PS) tube, a needle seat and an ovum peeling tube. The airbag, the PS tube, the needle seat and the ovum peeling tube are successively installed on the lower-middle portion of the rear shell from top to bottom, and a push button connected with a slide fastener is installed in the middle of the front shell. According to the novel test-tube baby ovum-peeling manipulator, the PS tube of the ovocyte sucking device is fixed inside grooves inside the front shell and the rear shell, the airbag is pressed to produce balanced sucking force during a using process, and other portions do not move. The novel test-tube baby ovum-peeling manipulator resolves the problem that granule cells on the periphery of an ovocyte cannot be sucked accurately or an embryo or the ovocyte cannot be transferred accurately through an existing test-tube baby ovum-peeling manipulator.

Description

A kind of New test tube baby shells the ovum operator

Technical field

The present invention relates to a kind of stripping ovum operator, particularly a kind of New test tube baby who is applicable to remove the granular cell around oocyte or shifts embryo and oocyte shells the ovum operator.

Background technology

Can there be following defective due to its structure in existing test-tube baby stripping ovum operator in use procedure:

1, shell the ovum operator when shelling the ovum operation, press rubber suction pipe button, will not shell oviduct because of shell and fix, rubber suction pipe disjunctor can occur and drive the stripping oviduct, can not draw accurately oocyte granular cell or transfer embryo and oocyte on every side.

2, when the operation of stripping ovum, because the external diameter of stripping ovum operator housing is meticulous, length is too short, operator's hands from the head of pipette very close to, operator's inconvenience is hand-held, easily be subjected to displacement in use procedure, can not draw very accurately oocyte granular cell or transfer embryo and oocyte on every side.

3, because the suction nozzle of test-tube baby stripping ovum operator is very little, suction is little, is not easy at short notice granular cell to be cleaned out.

4, existing part stripping ovum operator directly is connected with the stripping oviduct, and itself can not be sterilized processing, causes oocyte and culture fluid to pollute during use.

Summary of the invention

The object of the invention is to, provide a kind of New test tube baby to shell the ovum operator, it can overcome the defects that existing test-tube baby stripping ovum operator exists, to shell ovum operation pipe is connected with air bag by needle stand, PS pipe, the stripping oviduct can be do not driven during extruding gasbag, granular cell and oocyte can be accurately be drawn onto; And operator's hand-held is convenient, and during use, operator is not subjected to displacement, and can draw accurately oocyte granular cell or transfer embryo and oocyte on every side.Needle stand, PS pipe are easy to take out and pack into from stripping ovum operator with air bag.Needle stand, PS pipe can be sterilized or disposable use with air bag, avoid polluting culture fluid.

The present invention realizes above-mentioned purpose by the following technical solutions:

this New test tube baby shells the ovum operator by hand-held press device and draws oocyte device two parts and consists of, hand-held press device is by the depression bar cap, the cap for brush, back cover, spring, depression bar and fore shell consist of, draw the oocyte device by air bag, the PS pipe, needle stand and stripping oviduct consist of, it is characterized in that: the depression bar of described hand-held press device is contained in the upper end of back cover, the cap for brush is equipped with at the top, upper end of back cover, depression bar cap with the socket of the upper end of depression bar is housed in the cap for brush, the bottom of depression bar is set with spring, the middle part of back cover is connected to a fore shell by the hinge activity chain, push button is equipped with at the middle part of fore shell, slide fastener is housed on push button, push button is connected dog and is connected with hole clipping with slide fastener, the top of fore shell is manufactured with a spill arc groove, the PS pipe of described absorption oocyte device is fixed on the groove of fore shell and back cover inside, PS pipe upper end is set with an air bag, the lower end in contact of the top of air bag and depression bar, one side of air bag is embedded in the perforation of spill arc groove, the lower end of PS pipe is contained in the needle stand of back cover lower end, and the stripping oviduct is contained in the lower end of needle stand.

The present invention's beneficial effect compared with prior art is:

This New test tube baby shells ovum operator internal seat and air bag adopts silica gel material, and elasticity and air-tightness are good.Before and after be manufactured with three fixed grooves in housing, can be safe fix needle stand, PS pipe and air bag, when pressing pressuring gasbag in use procedure, other positions are not subjected to displacement, accurate positioning.Press the relation between design employing spring service load and deflection, the dynamics that is pressed on air bag when guaranteeing the use of stripping ovum operator is balanced.Appearance design becomes the shape of pen, good looking appearance, be convenient to hand-held, good hand touch during use.Its shell adopts ABS plastic material, and is nontoxic, tasteless, water absorption rate is low, and case hardness is good, is not easy to deform; The appearance design hommization, hand-held this operator of operator can adopt the operational approach of three kinds of simple and fasts to operate simultaneously.Solve existing stripping ovum operator and can not draw accurately oocyte granular cell or transfer embryo and oocyte on every side.Drawing the oocyte device can sterilize or disposable use.
