Abstract
The utility model discloses a kind of for acquiring the acquisition needle of soft-bodied insects body fluid, needle handle including cylindrical structure or polygon prism structure, the left part of the needle handle is gradually interior to receive, the left end of needle handle is arranged at intervals at least two and extends to the left, in coniform syringe needle, the syringe needle is solid core structure, and the length is 5~15 millimeters, the right part of needle handle is set with the operation handle extended to the right, the outer surface of the operation handle is provided with anti-skid chequer, and hanging ring is arranged in the right side of operation handle.The utility model advantage is that structure is simple, is convenient for hand-held, and inserting needle accuracy rate is high, reduces inserting needle number, disposably can pierce out two sepage mouths simultaneously and improve work efficiency so that insect body fluid quickly oozes out.Operation handle is flexibly connected with needle handle, is conveniently replaceable, and hanging ring is convenient for loft dried, sterilizing and storage, and protective cap effectively increases safety, prevents syringe needle from accidentally injuring experimenter in the non-use state.
Description
Technical field
The utility model relates to Bioexperiment auxiliary appliances, more particularly, to a kind of for acquiring adopting for soft-bodied insects body fluid
Collect needle.
Background technique
With scientific fast development, many soft-bodied insects (such as galleria mellonella waxmoth) are increasingly becoming biology, medicine and pharmacology and agriculture field
Important research object.In process of scientific research, it usually needs certain important components in acquisition animal body fluid are extracted, purified
And analysis.It is existing not dedicated for acquire soft-bodied insects body fluid collector, generally insect body wall is pierced with syringe needle
It is broken, it oozes out body fluid naturally, then acquires the body fluid of exudation.First is had the disadvantage that using syringe needle, injection
The pintle of device syringe needle is smaller, hard, and syringe needle is easy to slip when in use, cannot disposably puncture insect body wall；Needle stalk is longer, behaviour
It is inconvenient to make；Second, syringe needle is hollow structure, is easy residual insect body fluid in syringe needle, anti-inserting needle there are pollution risk, because
And be to avoid pollution every insect to need using a syringe needle, usage amount is big, waste of resource；Third needs to extract not
With the insect body fluid of growth phase, thus an insect at least needs more than two syringe needles, further increases injection
Device syringe needle usage amount, not only waste of resource, also adds syringe offal treatment amount.
Summary of the invention
The utility model aim is to provide that a kind of structure is simple and convenient to operate for acquiring adopting for soft-bodied insects body fluid
Collect needle.
To achieve the above object, the utility model takes following technical proposals:
The acquisition needle described in the utility model for being used to acquire soft-bodied insects body fluid, including cylindrical structure or polygon prism knot
The needle handle of structure, the left part of the needle handle is gradually interior to receive, and the left end of needle handle is arranged at intervals at least two and extends to the left, in circular cone
The syringe needle of shape, the syringe needle are solid core structure, and the length is 5~15 millimeters, the right part of needle handle is set with the behaviour extended to the right
Make handle, the outer surface of the operation handle is provided with anti-skid chequer, and hanging ring is arranged in the right side of operation handle.
The left part movable sleeve of the needle handle is equipped with protective cap, offers in the protective cap and to match with the syringe needle
Jack, syringe needle are inserted into the jack of protective cap.
The right part of the needle handle is provided with chuck along its circumferential direction, is provided in the operation handle and matches with the chuck
The card slot of conjunction.
The utility model advantage is that structure is simple, is convenient for hand-held, and inserting needle accuracy rate is high, reduces inserting needle number, can
Disposably two sepage mouths are pierced out simultaneously to improve work efficiency so that insect body fluid quickly oozes out.Operation handle and needle handle are living
Dynamic connection, is conveniently replaceable, and hanging ring is convenient for loft dried, sterilizing and storage, and protective cap effectively increases safety, prevents needle
Head accidentally injures experimenter in the non-use state.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, described in the utility model for acquiring the acquisition needle of soft-bodied insects body fluid, including cylindrical structure
Or the needle handle 1 of polygon prism structure, the left part of the needle handle 1 is gradually interior to receive, and the left end of needle handle 1 is arranged at intervals with two in circular cone
The syringe needle 2 of shape, horizontal extension, syringe needle 2 and needle handle 1 are cleaned, are sterilized thoroughly, can repeat to make to be seamlessly connected syringe needle 2 to the left
With economizing on resources；The syringe needle 2 be using solid core structure made of titanium steel material, the length is 5 millimeters, the right part of needle handle 1
It is set with the operation handle 3 extended to the right, the outer surface of the operation handle 3 is provided with anti-skid chequer, increases frictional force, anti-on-slip
It falls, hanging ring 4 is arranged in the right side of operation handle 3, convenient for suspension storage and drying；The left part movable sleeve of needle handle 1 is equipped with protection
Cap 5 offers the jack matched with the syringe needle 2 in the protective cap 5, and syringe needle 2 is inserted into the jack of protective cap 5, no
Syringe needle 2 can be only protected, is also convenient for storing, prevents syringe needle 2 from accidentally injuring experimenter.
As shown in Figure 1, the right part of needle handle 1 is provided with chuck 6 along its circumferential direction, it is provided in the operation handle 3 and institute
The card slot that chuck 6 matches, needle handle 1 and operation handle 3 is stated to be integrated by chuck 6, card slot clamping.
When practical manufacture, needle handle 1, operation handle 3 and protective cap 5 are all made of high-temperature resistance plastice, can be adapted to high temperature
Sterilization, disinfection, can reuse, and save experimental cost, avoid wasting.
In use, soft-bodied insects are fixed, then hand-held handle 3 is operated, so that syringe needle 2 is pierced into properly
Position, the body fluid after collecting exudation；Cleaning-sterilizing is carried out to this acquisition needle after use, protective cap 5 is then covered and is placed on specified deposit
Position is put, is sterilized using advance horizontal high voltage next time.
