Description

A kind of big mouse experiment continuous gavage device

Technical field

The utility model belongs to medical experimental vessel technical field, relates generally to a kind of big mouse experiment continuous gavage Device.

Background technology

Big mouse in animal is to select most frequent animal in medical research experiment, and to big mouse Jing in experimentation Often carry out the gavage operation of liquid.The gavage vessel for being adopted with big mouse stomach to experiment at present are syringes, in syringe Head adds a gavage syringe needle just can implement gavage to big mouse.But because every mouse need to pour into every time the gavage medicine being drawn onto in stomach Liquid has certain quantitative unit, and syringe can only disposably discharge all liquids due to the bad control of amount of liquid medicine discharged, so The gavage operation of many mouse is completed in experiment every time, it is necessary to continuously to gavage liquid is filled in syringe, i.e., Lose time also to affect experimental work efficiency.

Utility model content

For the problem in the presence of prior art, the utility model is designed and proposes a kind of big mouse experiment with continuously Irrigation stomach device, the irrigation stomach device that the utility model is proposed can disposably suck can continuously to the gavage amount of liquid medicine of at least 4～5 mouse, Aim to solve the problem that the syringe of current employing once can only need to frequently be inhaled repeatedly to a mouse gavage to during many mouse gavages Gavage liquid is taken, the big mouse stomach time is saved, the problem of experimental work efficiency is improved.

For achieving the above object, the concrete technical scheme that the utility model is taken is：A kind of big mouse experiment connects Continuous irrigation stomach device, including electric pipettor, are made up of mouse stomach pipe, rat oral gavage pipe, rack；Wherein：Mouse stomach pipe is adopted Make of the plastic conduit of hollow transparent；The top of mouse stomach pipe is straight tube-like, and the top of mouse stomach pipe is liquid medicine injection Entrance；Scale marker is carved with the side of mouse stomach pipe external wall of upper portion；It is processed into neck-shaped tubule, neck in the bottom of mouse stomach pipe The bottom mouth of pipe of shape tubule is round and smooth blunt mouth；Rat oral gavage pipe is made using the plastic conduit of hollow transparent, rat oral gavage pipe The upper and lower ends of top straight tube are in bottleneck shape, and the top of rat oral gavage pipe is provided with liquid inlet；Rat oral gavage pipe top it is straight Scale marker is carved with the side of pipe outer wall；It is processed into neck-shaped tubule, the mouth of pipe of neck-shaped tubule bottom in the bottom of rat oral gavage pipe For round and smooth blunt mouth；Rack is made up of base, metallic support rod, metal ring；Metallic support rod is welded in submounts Between position, metal ring is welded on the top of metallic support rod.Described a kind of big mouse experiment continuous gavage device, wherein greatly The liquid inlet on mouse gavage pipe top is identical with the caliber size of the liquid inlet on mouse stomach pipe top；Described one kind Big mouse experiment with many continuous stomach devices, wherein, the liquid inlet on rat oral gavage pipe top and the liquid on mouse stomach pipe top The caliber size of inlet is identical with the caliber size of pipettor glue head outlet on electric pipettor, and such inlet is inserted with bullet Will not fall off in the glue head of property；Described a kind of big mouse experiment multicapacity irrigation stomach device, wherein, mouse stomach tube capacity product is 4ml, is a scale per 0.1ml；Rat oral gavage tube capacity product is 8ml, is a scale per 0.1ml.

Big mouse experiment described in the utility model is simple, novel, practical with continuous gavage device structure design, in gavage pipe Fill after gavage liquid can one-time continuous operate to the gavage that 4～5 big mouse carry out liquid, when reducing each mouse gavage The lengthy and tedious operation of liquid must be again sucked in syringe, operating process is simple and feasible, effectively raise experimental work effect Rate.
