Abstract
The utility model discloses a living insect negative pressure fixing device. The living insect negative pressure fixing device comprises a base and an object shelf arranged on the base, a negative pressure cavity is formed between the base and the object shelf, a plurality of air holes are formed in the object shelf, and a negative pressure pipe which is connected with the negative pressure cavity is provided. According to the living insect negative pressure fixing device, negative pressure is generated in the negative pressure cavity through a negative pressure generating device connected with the negative pressure pipe, insects to be observed are placed on the object shelf, wings of the insects or bodies of the insects are adsorbed through the negative pressure at the bottoms of the air holes so as to fix the insects, the insects cannot be injured in the observing process, proceeding of follow-up experiments is facilitated, and the living insect negative pressure fixing device is used in the field of biological experiment devices.
Description
Technical field
The utility model relates to a kind of experiment device, particularly relates to a kind of living insects low-pressure holding device.
Background technology
Under the microscope the live bodies such as insect are observed conventionally and need to insect be fixed, while needing to observe insect live body in the past, conventionally adopt the first kill insects of airtight bottle, or fix insect by modes such as pinpricks.
Above two kinds of modes all can damage insect, are unfavorable for proceeding of subsequent experimental.
Utility model content
For addressing the above problem, the utility model provides a kind of living insects low-pressure holding device that can not damage insect.
The utility model solves the technical scheme that its technical problem adopts:
A living insects low-pressure holding device, comprises base and is arranged at the shelf on base, between base and shelf, be provided with negative pressure cavity, shelf is provided with some pores, is connected and is provided with negative tube with negative pressure cavity.
Be further used as the improvement of technical solutions of the utility model, base is transparent plastic piece, and negative pressure cavity is the groove that is arranged at base center.
Be further used as the improvement of technical solutions of the utility model, one end relative with negative pressure cavity on negative tube is connected with water flow generator.
Be further used as the improvement of technical solutions of the utility model, shelf is transparent plastic sheet.
The beneficial effects of the utility model: this living insects low-pressure holding device produces negative pressure by the depression generator being connected with negative tube in negative pressure cavity, insect to be seen is placed on shelf, negative pressure by pore bottom produces suction-operated with fixing insect to the wing of insect or health, in observation process, can not cause damage to insect, be beneficial to proceeding of subsequent experimental.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment base structural representation.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of living insects low-pressure holding device, comprises base 1 and is arranged at the shelf 2 on base 1, and 2 of base 1 and shelfs are provided with negative pressure cavity 11, shelf 2 is provided with some pores 21, is connected and is provided with negative tube 3 with negative pressure cavity 11.
This living insects low-pressure holding device by the depression generator that is connected with negative tube 3 in the interior generation negative pressure of negative pressure cavity 11, insect to be seen is placed on shelf 2, negative pressure by pore 21 bottoms produces suction-operated with fixing insect to the wing of insect or health, in observation process, can not cause damage to insect, be beneficial to proceeding of subsequent experimental.
As the utility model preferred embodiment, base 1 is transparent plastic piece, and negative pressure cavity 11 is for being arranged at the groove at base 1 center.
As the utility model preferred embodiment, shelf 2 is transparent plastic sheet.
As the utility model preferred embodiment, on negative tube 3, one end relative with negative pressure cavity 11 is connected with water flow generator.
Water flow generator can be the tap being directly connected with negative tube 3, or other current sources, current are through negative pressure cavity 11, in the interior generation negative pressure of negative pressure cavity 11, can hold by pore 21 wing or the health of insect, insect is fixed in the situation that insect not being damaged.
The size of the pore 21 on shelf 2 and density can be determined according to the insect size of required observation, reach best fixed effect.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
