Abstract
The utility model discloses a toy heart irrigator contains an irrigator section of thick bamboo, piston handle, pipe, three -way connector, support and fixed plate, an irrigator section of thick bamboo is fixed on the fixed plate through the support, the downside of piston handle is equipped with the rack, and the rack has a runner of outband gear, the runner is fixed on the support, is equipped with the handle on the runner, make runner rotation, runner drive piston handle back -and -forth movement through the handle. This kind of toy heart irrigator adopts runner and rack drive piston handle to impel or the extraction through fixing the irrigator on the fixed plate, only needs the one hand to operate, does not tremble, and efficient, stability is good, comparatively laborsaving, is even more ideal irrigator among doctor, the pharmacy animal experiment.
Description
Technical field
This utility model relates to a kind of doctor, pharmacy teaching and scientific experiment apparatus, is specially a kind of toy heart perfusion device.
Background technology
In doctor, pharmacy animal experiment study, toy experimentation, such as rat are the animal models of many experiment links, various experimentation, and drug metabolism and drug evaluation all need blood sampling and do pathological observation to corresponding organ.Conventional needs pours at heart place or gets blood, in the operation of heart aorta place, in operation due to toy heartbeat, or hand operation shake, make difficulty very large, get blood and easily cause haemolysis, it is accurate that rate of flooding and dosage are difficult to.Up to the present there is no effective tool can use, the experiences and skills entirely with individual operates.Therefore, improve operation easier, increasing the success rate of experiment, is urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of toy heart perfusion device.
For achieving the above object, the technical scheme of employing is:
A kind of toy heart perfusion device, comprise filling apparatus cylinder, piston handle, conduit, three-way connector, support and fixing head, described filling apparatus cylinder is fixed on fixing head by support, the downside of described piston handle is provided with tooth bar, tooth bar has the runner of band external gear, described runner is fixed on support, and runner is provided with handle; By handle, runner is rotated, driven by rotating wheel piston handle moves forward and backward.So just do not need held by both hands filling apparatus, and the injection port of filling apparatus can not be shaken, amount also relatively good assurance when advancing and extract.
The fixed support of described runner is also provided with pressure roller, and piston handle upper side pushed down by pressure roller.Like this joint efficiency can strengthening runner and piston handle is set, make it more stable and laborsaving.
Described three-way connector one end connects filling apparatus cylinder, and one end is for adding drug port, and one end is injection port.
Described three-way connector connects the two ends of adding drug port and injection port and is provided with circulation valve.
The beneficial effect of employing such scheme is: this toy heart perfusion device is by being fixed on fixing head by filling apparatus, runner and rack drives piston handle is adopted to advance or extract, one hand is only needed to operate, do not shake, efficiency is high, good stability, comparatively laborsaving, be doctor, more preferably filling apparatus in pharmacy zoopery.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model toy heart perfusion device.
Fig. 2 is the structural representation of connectors in this utility model.
In figure, 1-filling apparatus cylinder, 2-piston handle, 3-runner, 4-pressure roller, 5-handle, 6-conduit, 7-three-way connector.
Detailed description of the invention
Introduce this utility model further below in conjunction with drawings and Examples, but this utility model is not limited only to following embodiment, can predict those skilled in the art when in conjunction with prior art, performance may produce many variations.
Structural representation as shown in Figure 1, a kind of toy heart perfusion device, comprise filling apparatus cylinder 1, piston handle 2, conduit 6, three-way connector 7, support and fixing head, described filling apparatus cylinder 1 is fixed on fixing head by support, and the downside of described piston handle 2 is provided with tooth bar, and tooth bar has the runner 3 of band external gear, described runner 3 is fixed on support, runner 3 is provided with handle 5, by handle 5, runner 3 is rotated, and runner 3 drives piston handle 2 to move forward and backward.The fixed support of described runner 3 is also provided with pressure roller 4, and piston handle 2 upper side pushed down by pressure roller 4.
Filling apparatus cylinder 1 is fixed on fixing head by support, just do not need to use hand-held filling apparatus, the injection port of filling apparatus front end can not be shaken because of hand-held, advances and extract to adopt runner 3, tooth bar and pressure roller 4, singlehanded slowly turning handle, measure relatively good assurance, do not need to look at filling apparatus cylinder, do not shake, efficiency is high always, good stability, comparatively laborsaving.
As Fig. 2, described three-way connector 7 one end connects filling apparatus cylinder 1, and one end is for adding drug port, and one end is injection port.Three-way connector 7 connects the two ends of adding drug port and injection port and is provided with circulation valve.Drug port can add the medicine needing injection, can conveniently add medicine or reagent.
