Description
Technical field
The utility model belongs to mammalian in vitro fertilization auxiliary implement technical field, and in particular to a kind of hand-held negative-pressure
Adopt ovum device.
Background technology
Oocyte collection is the work that animal embryo engineering is often carried out from discarded ovary, generally, there is two
Plant solution, 1）Extracted by hand with syringe.Method is to draw a certain amount of culture medium in syringe first, then by pin
Head is pierced into ovarian follicle and adopts ovum.Its advantage is that cost is low, can take field work to, but has the disadvantage that operating efficiency is low, and can be disappeared
The excessive culture medium of consumption, so that the ovoscopy work to next step makes troubles.
2）Extracted using negative pressure pump.Method is opened after negative pressure pump, due to continued presence negative pressure, syringe needle can be used continuous
Ovum is adopted, efficiency is higher, and the culture medium used is less, has the disadvantage, negative pressure pump is often larger, is only suitable in experiment in-house operation,
Be not suitable for taking field work to.
Utility model content
The problem of the utility model exists for instrument used in existing oocyte collection and deficiency make there is provided one kind
Ovum device is adopted with the hand-held negative-pressure of convenience and high-efficiency.
The utility model solves the scheme that its technical problem used：A kind of hand-held negative-pressure adopts ovum device, including negative
Pressure device and take ovum pin, the negative pressure device is included with handled gun body, and negative pressure bag is fixed with gun body handle inner chamber, bears
The lower end of briquetting is connected with outer negative tube, outer negative tube and is provided with the joint being connected with negative pressure device；Negative pressure wraps end connection
Have and negative tube open and close valve is installed on interior negative tube, negative tube, negative tube open and close valve links with hand switch；The gun body front end
It is fixed with and takes ovum pin, gun body front lower portion, which is sealedly connected with, stockpiles bottle, described the inner for taking ovum pin is described interior positioned at stockpiling in bottle
Negative tube is communicated in after filter and stockpiled in bottle.
The negative tube open and close valve includes being provided with open and close valve driving lever on valve body and internal valve plate, the valve plate, described
Hand switch is that dead axle is set in gun body and trigger is provided with, and described trigger the inner is provided with shift fork, the shift fork matching card
It is connected on open and close valve driving lever.
The beneficial effects of the utility model：The utility model assures the keying on road using negative pressure in control gun body manually, very
Easily operation, reaching flexibly to move, the purpose manipulated at any time.
The utility model is simple in construction, easy-to-use efficiency high, can be used in laboratory, can take field to and use, section
About culture medium, facilitates later stage ovoscopy.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Label in figure, 1 is gun body, and 2 be inner support, and 3 be negative pressure bag, and 4 be negative tube open and close valve, and 5 be open and close valve driving lever, 6
For filter, 7 is take ovum pin, and 8 be joint for sealing connecting, and 9 is stockpile bottle, and 10 be hand switch, and 11 be outer negative tube, and 12 be interior negative
Pressure pipe one, 13 be interior negative tube two, and 14 be seal plug.
Embodiment
Hand-held negative-pressure adopts ovum device as shown in figure 1, including a gun body 1, gun body 1 carries hand switch 10.In gun body 1
Portion is provided with negative pressure device.
Specifically, negative pressure bag 3 is fixed with the handle inner chamber of gun body 1, the lower end of negative pressure bag 3 is connected with outer negative tube 11,
The joint being connected with negative pressure device is installed on outer negative tube 11.When insufficient pressure in negative pressure bag 3, by outer negative tube 11 with
Negative pressure device is connected, and extracts the air inside negative pressure bag 3.
The upper end of negative pressure bag 3, which is connected with interior negative tube, negative tube, is provided with negative tube open and close valve 4, negative tube open and close valve 4 with
Hand switch 10 links.Start before hand switch 10, the interior negative tube 1 positioned at the front end of negative tube open and close valve 4 is normal pressure shape
State, the interior negative tube 2 13 positioned at negative tube rear end is negative pressure state.Start after hand switch 10, interior negative tube 1 and interior negative
Pressure pipe 2 13 is all negative pressure state.
Gun body 1, which is fixedly arranged at the front end with, takes ovum pin 7, and the front lower portion of gun body 1, which is sealedly connected with, stockpiles bottle 9, described to take the interior of ovum pin 7
End, which is located at, to be stockpiled in bottle 9, and the interior negative tube is communicated in after filter 6 to be stockpiled in bottle 9.
The negative tube open and close valve 4 includes being provided with open and close valve driving lever 5, institute on valve body and internal valve plate, the valve plate
It is that dead axle is set in gun body 1 and trigger is provided with to state hand switch 10, and described trigger the inner is provided with shift fork, the shift fork
With being connected on open and close valve driving lever 5.
The application method of the utility model said apparatus：Certain negative pressure is produced first by manual negative pressure device, then
With switch manual switch 10, ovum syringe needle will be taken to be pierced into after ovarian follicle, open negative pressure, exhaust closing.
