Abstract
The utility model discloses a ration straw relates to a medical apparatus field, store the liquid bag and inhale the bag including liquid pipe, two, inhaling the bag and storing liquid bag intercommunication with two respectively through two gas conduits, liquid pipe, tubule and two store the liquid bag through two lower liquid pipe interconnected. During the use, take up ration straw, the bag is inhaled in the extrusion, dipes the liquid sample with ration straw imbibition mouth, comes up and inhales the bag, makes liquid sample full of liquid pipe, and unnecessary liquid flows down through the lower extreme opening of two lower liquid pipes, stores in two are store the liquid bag, and the rethread extrusion is inhaled the bag and is detected in emiting into corresponding detection zone with liquid. The utility model relates to an it is ingenious, simple structure, convenient operation, the ration is accurate, and the ration of suitable liquid is moved and is got.
Description
Technical field
The utility model discloses a kind of quantitative straw, relate to a kind of field of medical appliances.
Background technology
In medical vitro diagnosis assays field, usually need sample amounts to be added drop-wise in the checkout gear of analysis, carry out detection and analyze.At present, mainly use liquid-transfering gun application of sample, but cost is high, operation inconvenience.If run into when having large batch of sample Water demand, use liquid-transfering gun also more consuming time.
Summary of the invention
The purpose of this utility model is to provide a kind of quantitative straw, detects with the quick collection realizing liquid sample in enormous quantities.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of quantitative straw, comprise liquid conduits, the first reservoir, the second reservoir, inhale capsule, described suction capsule is communicated with the first reservoir by the first gas conduit, inhale capsule to be communicated with the second reservoir by the second gas conduit, liquid conduits, tubule and the first reservoir and the second reservoir are interconnected by first time liquid pipe and second time liquid pipe.
Preferably, described suction capsule, the first reservoir and the second reservoir are elliposoidal.
Preferably, described first reservoir and the second reservoir are symmetrical, and volume is greater than suction capsule.
Preferably, described liquid conduits lower end is provided with liquid sucting port.
Preferably, described tubule upper end is sealing.
Preferably, described first time liquid pipe and second time liquid pipe are symmetrical.
Preferably, described first gas conduit and the second gas conduit are symmetrical.
Preferably, between described suction capsule and the first reservoir, the second reservoir and the first reservoir, be provided with support portion between the second reservoir and liquid conduits, for quantitative straw provides rigid support, strengthen the structural strength of suction pipe, make more convenient to operate.
Preferably, described liquid conduits is tapered from the bottom to top, and liquid conduits hypomere is the thickest, and liquid conduits stage casing is comparatively thin, and liquid conduits epimere is the thinnest.When liquid is inhaled into, because liquid conduits is tapered, can produce larger flowing velocity at liquid travels from liquid conduit epimere, the probability making liquid hang over two lower liquid pipe lower ending openings reduces, thus quantitative straw can not be caused a deviation because of containing liquid, add the accuracy of quantitative straw.
By implementing technique scheme, the utility model achieves following beneficial effect:
The utility model design is ingenious, makes surplus liquid flow into reservoir, reach quantitative object by two lower liquid pipes; Being tapered by arranging liquid conduits, avoiding because cause error containing liquid, adding the accuracy of quantitative straw.Being greater than by arranging two symmetrical volumes the reservoir inhaling capsule, making reservoir can store more surplus liquid, making quantitative straw reach reusable object.By arranging gripper shoe, being quantitative straw stabilized structure, achieving the stability of hand-held.
