Description
This utility model relates to a kind of animal experiment device capable, particularly a kind of unconstrained animal infusion set rotator.
In the medical faunae test, often need carry out the fistulation pipe laying test that some long-time continuous are observed.At first, this test is that animal is strapped on the special position, carries out under the condition that animal can not move.Because the irritability of animal reaction, the effect of this method is very undesirable.Afterwards, people have invented a kind of metabolic cage transfusion system, this system can carry out work under the unrestraint situation of laboratory animal, alleviated the misery of laboratory animal, reduced the irritability reaction of animal, improved the verity and the reliability of experiment, made medical animal experiment step into a brand-new stage.This transfusion system comprises parts such as metal backing button, rotator and infusion pump, and is easy to use.But, directly link to each other between the liquid control section of this transfusion system rotator and the conducting tube, along with the motion of animal, the wrapping phenomena of conducting tube usually can take place, the carrying out of influence test.
The purpose of this utility model provides a kind of unconstrained animal infusion set rotator that can not twine.
The purpose of this utility model realizes by following design: a kind of unconstrained animal infusion set rotator, comprise liquid control section and liquid conductive part, described liquid control section comprises extension tube attached, small pinhead, big syringe needle and outer housing, described extension tube attached upper end is a free-end, the lower end is stretched in the needle stand that is fixed in described small pinhead, the shank of described small pinhead is inserted in the needle stand of described big syringe needle, one end of described outer housing is fixed on the tube wall of described extension tube attached, the other end is free, this free-end has a diameter less than described big needle seat external diameter, greater than the hole of described large needle scalp acupuncture bar external diameter; Described large needle scalp acupuncture bar is by passing in the described hole, and links to each other with a short arm of force with described liquid conductive part.
In order to prevent air admission, and the shank of small pinhead can be rotated more freely in big needle seat, in described big needle seat, sheathed one " O " type ring that fills lubricant on the shank of described small pinhead.
The utility model has the advantages that:
1, the shank owing to small pinhead can rotate in big needle seat freely, and there is the short arm of force to link to each other between liquid control section and the liquid conductive part, so no matter how laboratory animal moves, the spring serpentine pipe can not twine, and has fundamentally solved conducting tube and has twined the influence that brings to experiment.
2,, thereby make the spring serpentine pipe activity of the short arm of force get up more flexible, smooth because as being provided with the copper core between the spring serpentine pipe of the short arm of force and the large needle scalp acupuncture bar.
3, the conduction flexible pipe is coated in the spring serpentine pipe, can prevent effectively that cracking between the teeth of animal sting.
4, set up outer housing separately at the liquid control part, the small pinhead shank is rotated in big needle seat freely in, be unlikely in big needle seat, to deviate from, and can play the effect of protection extension tube attached, small pinhead and big syringe needle, and can prevent dust.
5, owing to sheathed one " O " type ring on the shank of small pinhead, the lubricant in " O " type ring can play the effect of secluding air, sealing, can also reduce friction, and prevents fluid seepage.
6,, for the dismounting sterilization or take out animal in the cage at any time and weigh, all very convenient owing to be the relation of pegging graft between the syringe needle.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A cutaway view of Fig. 1
As shown in Figure 1, this utility model comprises liquid control and liquid conductive two parts; The liquid control section comprises extension tube attached 1, small pinhead 2, big syringe needle 3 and outer housing 8, and extension tube attached 1 is taken over end dissociative on it for hard, can link to each other with infusion pump etc., the lower end of extension tube attached 1 swells and is nipple-like, is solidly plugged in the needle stand of small pinhead 2, can glue mutually by natural gum between them; The shank of small pinhead 2 inserts in the needle stand of big syringe needle 3; One end of outer housing 8 is fixed on the tube wall of extension tube attached 1 by plug 9, the other end is free, this free-end has a diameter less than big syringe needle 3 needle stand external diameters, hole greater than big syringe needle 3 shank external diameters, big syringe needle 3 shanks are by passing in this hole, and link to each other with the short arm of force 6 of a spring serpentine pipe with the liquid conductive part; Conducting tube partly comprises conduction flexible pipe 4 and spring serpentine pipe 5, and conduction flexible pipe 4 is arranged in the tube chamber of spring serpentine pipe 5, and an end of conduction flexible pipe 4 joins with the shank of big syringe needle 3, and the other end is free, is embedded in the experimental animals during application; Spring serpentine pipe 5 and the one of the short arm of force 6 of the spring serpentine pipe on being socketed in big syringe needle 3 shanks for linking to each other, its free-end can link to each other with the metal backing button 11 on being fixed on the animal health; Outer housing 8 of the present utility model can be that multiple materials such as glass, plastics are made, and can be transparent, also can be opaque, and extension tube attached 1, small pinhead 2, big syringe needle 3 can be metal, multiple material such as mould firmly makes.
For the shank that makes small pinhead 2 can rotate in big syringe needle 3 needle stands more freely, simultaneously also for secluding air, seal, as shown in Figure 1, in the above-described embodiments, in the needle stand of big syringe needle 3, sheathed one " O " type ring 10 on the shank of small pinhead 2, fill lubricant in " O " type ring 10, lubricant can also reduce the friction between small pinhead 2 shanks and " O " type ring 10.
In order to increase the steadiness of the short arm of force, as shown in Figures 1 and 2, in the above-described embodiments, between the shank of big syringe needle 3 and spring serpentine pipe 6, establish 1 bronze medal core 7, copper core 7 outer walls are embedded in the spring serpentine pipe 6, and copper core 7 outer walls are fixed on the shank of big syringe needle 3, and the gluing company of usable resins between the shank of copper core 7, spring serpentine pipe 6, big syringe needle 3 also can weld.
Operation principle of the present utility model is, extension tube attached 1 connects infusion pump, and the conduction flexible pipe 4 of reservation inserts in the animal bodies, and the metal backing button is sewn under the animal skins, then transfusion.Liquid enters in the animal body by extension tube attached 1, small pinhead 2, big syringe needle 3, conduction flexible pipe 4 successively, and in the experiment, laboratory animal can arbitrarily be walked about, and wrapping phenomena can not take place.This utility model is mainly used in the pipe laying fistulation experiment of rat and Cavia porcellus.
