Description
Technical field
The utility model relates to experimental animal apparatus more particularly to a kind of for the true of relatively large experimental animal Culling heart blood
Lost motion object blood collection external member.
Background technique
Blood collection is a most basic, most common technical step in scientific research, is usually needed in all kinds of experiments
The blood for acquiring animal in large quantity by cardiac puncture carries out scientific research detection.The big animal blood such as traditional dog, rabbit, chicken is adopted
When collection, after deep anaesthesia, blood collection is carried out using negative tube or syringe cardiac puncture, syringe needs constantly continuous take out
It takes, and negative tube single blood sampling volume is few, needs constantly to replace negative tube.It can be seen that no matter using the entire mistake of which kind of equipment
Journey is not only time-consuming, laborious, and also usually because blood sampling slowly leads to most of blood clotting, causes to waste, and then influence is tested
Process and result.For experimental animal, not being is not a kind of injury outside anticipation.
Summary of the invention
The purpose of this utility model is directed to a kind of blood collection kit of experimental animal, solves to promote scale blood sampling effect
Rate prevents the problem of blood loss.
The utility model realizes that the technical solution of above-mentioned purpose is the blood collection kit of experimental animal, it is characterised in that
By transformation cavity, suction unit and storage blood container constitute, wherein the transformation cavity have ventilated membrane separate the first space and
Second space, the connection wherein the first space connects with suction unit, second space are equipped with the connector of connection blood-collecting needle tube, connection storage
The blood of blood container exports and blood sampling path therebetween.
Further, the suction unit is at least one of electric vacuum pump or manual suction pump.
Further, the ventilated membrane is hydrophobic air permeable film, and ventilated membrane is ventilative to the first direction in space along second space
And liquid-tight.
Further, the storage blood container is at least one of vacuum bag or disposable blood collecting bottle.
Further, the storage blood container bottom, which is equipped with, takes the switch that blood uses for external tool.
Further, the blood-collecting needle tube is connected by conduit with the connector of second space, and the storage blood container is by leading
It manages and is connected with the outlet of the blood of second space.And the length of conduit is 3cm or less at two.
Further, first space is formed by conduit external connection suction unit, the suction unit periodically pumping
Subnormal ambient in transformation cavity.
Using the blood collection kit of the utility model, have substantive distinguishing features and progressive: the external member structure is simple, is suitable for body
The biggish animal of shape carries out the scale blood sampling of cardiac puncture, and easy to operate and fault rate is low；Blood sampling path is shortened, it can be effective
Avoid blood collection procedure pollution and and and evaporation, guarantee the accuracy of experimental data with this.
Detailed description of the invention
Fig. 1 is the general assembly structural schematic diagram of the utility model blood collection kit.
Specific embodiment
Just attached drawing in conjunction with the embodiments below, is described in further detail specific embodiment of the present utility model, so that this
Utility model technical solution is more readily understood, grasps, to make relatively sharp define to the protection scope of the utility model.
In view of existing many deficiencies for big animal blood taking equipment aspect, the design person is researched and analysed and innovates proposition
A kind of blood collection kit of experimental animal can reduce the cumbersome degree of experimenter with this, solve to promote scale blood sampling
Efficiency prevents the problem of blood loss.
As shown in Figure 1 as it can be seen that the blood collection kit of experimental animal general introduction scheme, by transformation cavity 1,2 and of suction unit
It stores up blood container 3 to constitute, the first space 11 and second space 12 that wherein there is transformation cavity 1 ventilated membrane 4 to separate, wherein first is empty
Between 11 connect with suction unit 2 connection, second space 12 is equipped with the connector 121 of connection blood-collecting needle tube 5, connection storage blood container 3
Blood outlet 122 and blood sampling path therebetween.Under the composed structure and connection relationship, the first space 11 passes through conduit external connection air-breathing
Unit 2, and suction unit periodicity Automatic-bleeding can form the negative pressure ring of most of component especially transformation cavity in external member
Border, to keep certain blood sampling speed.
Specified otherwise is needed, above-mentioned ventilated membrane is hydrophobic air permeable film, and ventilated membrane is along second space to the first space
Direction is breathed freely and liquid-tight.I.e. with the pumping action of suction unit, remaining air can be constantly by ventilative in second space
Film dissipation, and wherein extracted blood will be unable to flow by the ventilated membrane in storage blood container.The ventilated membrane is used to separate
Liquid in first space and blood sampling path, this efficiency of also controllably taking a blood sample for suction unit provide guarantee.
Further refinement and optional embodiment, the suction unit as above scheme are at least electric vacuum pump or hand
One of dynamic aspiration pump.Electric vacuum pump needless to say, as long as rationally the control start-stop time and vacuumizing intensity, and hand
Dynamic aspiration pump needs to meet enough operation eases, such as the modes such as two refer to pressing, and slight foot is stepped on, without experimenter carry out into
Significantly movement is advisable row.
Above-mentioned storage blood container can be vacuum bag and a kind of most common storage blood container, naturally it is also possible to be disposable
Blood collecting bottle, test tube or other similar containers.
Further, above-mentioned storage blood container bottom, which is equipped with, takes the switch that blood uses for external tool.It is taking a blood sample in this way
After, storage blood container can be transferred to other laboratories, can be used for subsequent experimental easily after opening this switch.
From diagram as it can be seen that above-mentioned blood-collecting needle tube is connected by conduit with the connector of second space, the storage blood container passes through
Conduit is connected with the outlet of the blood of second space.And shorten length as far as possible while the length of conduit meets operation ease at two
Degree, it is intended to enable and acquire resulting blood by as often as possible income storage blood container, and be unlikely to be wasted in pipeline.When leading
Pipe pull out after wherein remaining blood will go bad at once and be safely handled.
To sum up about embodiment detailed description as it can be seen that using the utility model blood collection kit, have substantive distinguishing features
And progressive: the external member structure is simple, carries out the scale blood sampling of cardiac puncture suitable for the biggish animal of the bodily form, it is easy to operate and
Fault rate is low；Shorten blood sampling path, can effectively avoid blood collection procedure pollution and and and evaporation, experimental data is guaranteed with this
Accuracy.
The utility model is described in detail above by specific embodiment, which is only the utility model
Preferred embodiment, not to the restriction of requested protection scope.In the case where not departing from the utility model principle, ability
Any modification, equivalent substitution and improvement that domain those of ordinary skill is done under the premise of without creative work it is obtained its
Its embodiment, is regarded as in the technical protection scope of the utility model.
