A kind of new metabolism group sample weighing medicine spoon
Technical field
The utility model is related to a kind of new metabolism group sample weighing medicine spoon.
Background technology
After the laboratory sample that in metabonomic analysis test, low temperature is lyophilized is ground into powder, need accurately to weigh a certain amount of
Powdered samples extracted and tested, sample size is generally fewer, thus weighing operation require higher.Existing common
Small dimension claims sample spoon capacity little, often powdered samples is sprinkled upon outside sample bottle, or sample is bonded at sample during use
Product bottleneck, causes the waste of sample.
Utility model content
In order to solve the above problems, the utility model proposes a kind of new metabolism group sample weighing medicine spoon, can be accurate
Weigh powder sample, and avoid unnecessary loss, the cleaning of sample spoon is easier, and improves experimental implementation efficiency.
The utility model to be realized particular by technical scheme below:
A kind of new metabolism group sample weighing medicine spoon, including medicine spoon, sleeve, spring, baffle plate and pushing block, the one of described medicine spoon
End is provided with one section of elongated channel-shaped, and the other end is fixed on baffle plate, the end of described trench-like extension to medicine spoon;Described medicine spoon is from set
The insertion of cylinder one end, in sleeve, described baffle plate is fixed on the other end of sleeve by spring to described baffle plate setting;Outside described sleeve
Wall is provided with chute, and described pushing block is placed in chute and described pushing block is fixed on baffle plate.
Preferably, described channel-shaped is circular groove structure.
Preferably, the end being in the medicine spoon of described channel-shaped one end is oblique, and is triangle in plane projection.
What the utility model produced has the beneficial effect that compared with prior art, uses this utility model accurate in laboratory
Weigh during powder sample will not by a large amount of samples be bonded at sample bottleneck or and bottle wall, also will not be sprinkled upon outside sample bottle, it is to avoid need not
The loss wanted, the cleaning of sample spoon is easier, and more convenient operation is simple, improves experimental implementation efficiency.
Brief description
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is perspective view of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the utility model protection.
A kind of new metabolism group sample weighing medicine spoon as shown in Figure 1-2, including medicine spoon 1, sleeve 3, spring 4, baffle plate 5 with push away
Block 6, one end of described medicine spoon 1 is provided with one section of elongated channel-shaped 2, and the other end is fixed on baffle plate 5, and described channel-shaped 2 extends to medicine
The end of spoon 1;Described medicine spoon 1 inserts from sleeve 3 one end, and described baffle plate 5 is arranged in sleeve 3, and described baffle plate 5 passes through spring 4
It is fixed on the other end of sleeve 3;Described sleeve 3 outer wall is provided with chute 7, and described pushing block 6 is placed in chute 7 and described pushing block 6 is solid
It is scheduled on baffle plate 5;Described channel-shaped 2 is circular groove structure.
The part of the channel-shaped 2 of the utility model Chinese medicine spoon 1 wants smooth enough, and flute mark depth rationally will be in described channel-shaped 2
The end of the medicine spoon 1 of one end is oblique, and in plane projection for triangle it is ensured that contact area is as little as possible, also will not
Stick powder medicaments.Traditional sample spoon is transformed by this medicine spoon, and spoon part is designed to elongated channel-shaped, can contain and take on a small quantity
Sample, and directly sample can be delivered to the bottom compared with sample vial, reduce the loss of sample at bottleneck and bottle wall, channel-shaped
The surface area ratio of spoon is larger, more preferably clears up, and is easy to use next time.
In actual use, after filling powder medicaments in channel-shaped 2, promote pushing block 6, spring stretches simultaneously,
Baffle plate 5 travels forward and for medicine spoon 1 to be pushed to sample bottle bottom;After powder medicaments all import to sample bottle, unclamp pushing block 6, by
In spring 4 elastic returning to nature, medicine spoon 1 is driven to retract reply reset condition.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in the utility model
Protection domain within.
