Detailed description of the invention
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
See accompanying drawing, accompanying drawings provide a kind of specific embodiment of gavage device, as as described in accompanying drawing, this gavage device comprises pedestal 1, pedestal 1 is provided with support bar 2, support bar 2 upper end is provided with four-way union 3, four-way union 3 is provided with the first joint 301, second joint 302, the 3rd joint 303 and the 4th joint 304, is provided with the unlatching of switch valve 305 for each joint passage with closed in four-way union 3.
First joint 301 is connected with breather 5 and described breather 5 extend to always described support bar 2 lower end arrange test tube 4 in, during use, a certain amount of water is added in test tube 4, breather 5 is submerged completely in water and makes water level higher than breather 5 opening certain altitude, so, when there being gas to flow into test tube 4 from breather 5, the water in test tube 4 then can emit bubble, then can distinguish that whether following medicine output duct 8 on position is correct, play safe warning function in time.
Second joint 302 is connected with drug delivery device 6, and drug delivery device 6 is mainly used in import animal gastric by following medicine output duct 8 in infusion of medicine to be tested to four-way union 3.
3rd joint 303 is connected with abluent input equipment 7, abluent input equipment 7 is mainly used in injecting abluent in four-way union 3, medicine residual on following medicine output duct 8 inwall is all cleaned and pours animal gastric, Enhancement test result accuracy.
4th joint 304 is connected with medicine output duct 8, and medicine output duct 8 is mainly used in medicine and abluent to import animal gastric.
Support bar 2 is connected with mechanical hand 9, mechanical hand 9 head end 901 is connected with support bar 2, and mechanical hand 9 tail end 902 is provided with gag 10.In the present embodiment, bending and stretching or rotating by mechanical hand 9, operator can operate in certain scope, the use of more convenient operator, meanwhile, by gag 10, can open easily and the mouth of fixing animal, facilitate following perfusion operating process.
When specifically carrying out the experiment of medicine gavage, mainly comprise the steps:
First, in test tube 4, add a certain amount of water, and make the degree of depth of water exceed breather 5 opening certain altitude, regulate the switch valve 305 arranged in four-way union 3 to be opened by first joint 304 place passage;
Secondly, whether medicine output duct 8 is inserted animal gastric, and observes in test tube 4 and have bubble to emerge, whether misplug enters in animal trachea detection of drugs output duct 8 thus, if have bubble to emerge in test tube 4, then show medicine output duct 8 wrong plug position (mistake inserts tracheal strips); If bubble-free is emerged in test tube 4, then show medicine output duct 8 on position correct (inserting gastric);
Again, after determining that medicine output duct 8 inserts gastric, regulating the switch valve 305 arranged in four-way union 3 by the first joint 304 place pathway closure, starting to treating laboratory animal gastric input medicine by the drug delivery device 6 that the second joint 302 connects;
Finally, then inject abluent by the abluent input equipment 7 that the 3rd joint 303 connects medicine residual in four-way union 3 and medicine output duct 8 is all poured animal gastric.
In this programme, when being necessary, can also by drug delivery device 6 and abluent input equipment 7 back suction gastric mixture with the correlation circumstance of detection of drugs gavage process.
Generally, by this device, can safety carry out gavage operation, avoid drugs delivery trachea, meanwhile, medicine residual in each mechanism all can be poured gastric, the accuracy of Enhancement test result by abluent input equipment 7; And, for this device, only need people's operation can complete whole gavage process, convenient and simple, greatly save manpower and materials cost.
In the present embodiment, for better realizing the adjustment of gag 10, gag 10 comprises ramus maxillaris frame plate 1001 and ramus of mandible frame plate 1002, is provided with width adjusting device 1003 between described ramus maxillaris frame plate 1001 and ramus of mandible frame plate 1002.So, the A/F of gag 10 can be regulated by width adjusting device 1003, adapt to the laboratory animal of all size further and need A/F size, the operation of handled easily personnel.In the present embodiment, width adjusting device 10 is preferably expansion screw.
In the present embodiment, for increasing the working place of mechanical hand 9 further, be provided with bearing 11 between support bar 2 and mechanical hand 9, support bar 2 is arranged in bearing 11 inner ring, and mechanical hand 9 head end is set on bearing 11 outer ring.So, mechanical hand 9 can rotate for axle center with support bar 2 within the scope of 360 degree, can further facilitate the operation of operator.
In the present embodiment, for better realizing the determination of medicine and abluent input quantity and for realize aforesaid operations more easily, drug delivery device 6 and abluent input equipment 7 are syringe.Because all can scale be had above syringe, so very convenient when the control of injection of medicine amount, meanwhile, also very simple and convenient when operation, only need by the piston in syringe toward pressing down.
In the present embodiment, consider that normal saline is easy to obtain, and it generally can not have an impact to the property of medicine of medicine, the abluent arranged in abluent input equipment 7 is preferably normal saline.
Above a kind of gavage device provided by the utility model is described in detail.Should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also carry out some improvement and modification to this utility model, these improve and modify and also fall in the protection domain of this utility model claim.
