Abstract
The utility model discloses a kind of simple, safety tree shrew gavage device, including syringe, stomach tube and opener, the endcapped of the stomach tube is simultaneously provided with aperture in end profile, head end is the openend of connection syringe pin hole, openend carries flexible glue lid, the gavage medicine that injector syringe is connected in openend, syringe after flexible glue lid is opened to reach in stomach by stomach tube.This gavage device combines the dietary habit of tree shrew, small-bore people is applied to tree shrew with silica gel stomach tube, damage tree Shrew gastrointestinal mucosals are difficult when throwing pipe while easily can insert the stomach tube other end in sterilized water, once occurring mispluging in tracheae situation water and will produce bubble, there is suggesting effect for the operation error of staff, reduce the situation for mispluging tracheae, improve security, because tree shrew tooth is sharp, Baoding that opener is beneficial to tree shrew is added, being smoothed out for gavage has been ensured；Prepared by the utility model convenient, and cost is low, safety simple to operate.
Description
Technical field
The utility model belongs to experimental animal instrument field, more particularly to a kind of simple, safety tree shrew gavage device.
Background technology
Tree shrew has small, easily raises, management is convenient, cheap economical, and its evolution degree is high, metabolism and substantially
Dissection is than animals and human beingses such as dog, big mouse more closely, anatomical structure is also similar to people, and therefore, it is used as comparatively ideal reality
Animal is tested, has been widely used in the research of Med Biol.Zoopery utilization in, according to evaluate purpose,
The difference of pharmaceutical dosage form, dosage, can take tree shrew different medications, and the medication of oral gavage is a kind of among these
Very important approach.Prior art is usually using a kind of special hollow needle with standard syringe interface.Using this
During kind of irrigation stomach device, the decoction of syringe cavity will be drawn into via being properly inserted into animal esophagus by pushing syringe handle
In the hollow needle and be expelled to the stomach of experimental animal.But the rigid structure of this irrigation stomach device, experimental animal can be disappeared
Change road and produce a certain degree of injury.Secondly, tree shrew natural disposition agility is active, tooth is sharp, and patient can not fix gavage dress very well
Put, the generation for situations such as causing gavage failure, misplug tracheae, gastrointestinal mucosal more macrolesion, so as to be difficult to objective evaluation experiment
The pharmacology and toxicologic index of medication.
The content of the invention
The utility model is intended to fill there is provided a kind of simple, safety tree shrew for above-mentioned the deficiencies in the prior art
Stomach device, the gavage device is used for the gavage for testing tree shrew, has not only ensured being smoothed out for gavage, and can avoid filling
Tree shrew is damaged during stomach and simple, easy to use.
The utility model is achieved through the following technical solutions：
A kind of simple, safety tree shrew gavage device, including syringe, stomach tube and opener, the end envelope of the stomach tube
Close and be provided with aperture in end profile, head end is the openend of connection syringe pin hole, and openend carries flexible glue lid, opens flexible glue
The gavage medicine that injector syringe is connected in openend, syringe after lid is reached in stomach by stomach tube.
It is preferred that, the stomach tube be disposable people's stomach tube, made by the silica gel material of soft texture, to mucous membrane of animal without
Damage, internal diameter 1mm.
It is preferred that, the opener selection does not damage the passivity batten of tree shrew tooth and oral mucosa, long generous for 10cm
×1cm×0.5cm；The through hole greater diameter than stomach tube is opened in stage casing, stomach tube is inserted in through hole.The opener both ends are used
Flexible material, flexibility is fixed on tree shrew oral cavity, stomach tube via through holes is passed through oral cavity, and reaching stomach into esophagus is finally completed
Medicine gavage.
It is preferred that, the big I of syringe is arbitrarily changed, dosage easy to control.
This gavage device that the utility model is provided can be used in testing tree shrew, and this gavage device combines the life of tree shrew
Life habit is managed, small-bore people is applied to tree shrew with silica gel stomach tube, damage tree Shrew gastrointestinal mucosals are difficult while can when throwing pipe
Easily the stomach tube other end is inserted in sterilized water, once bubble will be produced by occurring mispluging in tracheae situation water, for work people
The operation error of member has suggesting effect, reduces the situation for mispluging tracheae, improves security, because tree shrew tooth is sharp, increases
Add opener to be beneficial to Baoding of tree shrew, ensure being smoothed out for gavage；It can avoid causing tree shrew during gavage
Injury, has accomplished simple and safe and convenient to use.Prepared by the utility model convenient, and cost is low, safety simple to operate.
Brief description of the drawings
Fig. 1 is combination diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings 1 and specific embodiment further describe the utility model, advantage of the present utility model and spy
Point will be with description and it is apparent.But the following examples are only exemplary, not to protection model of the present utility model
Enclose any limitation of composition.
The present embodiment is used exclusively for testing a specific embodiment of tree shrew gavage device.
The present apparatus is divided into three parts：2ml syringes 1, the disposable people of long 15cm are with No. 6 stomach tubes 2 and opener 3.It is described
Disposable people opens an aperture 2mm apertures 4 with No. 6 stomach tubes 2, internal diameter 1mm endcapped in the end profile, other end
Head end is openend 5 and is provided with flexible glue lid 7, and openend is the construction of connection injector syringe；Flexible glue lid 7 is used for closing open end
5, flexible glue lid opens rear open end and injector syringe connection, and stomach tube openend 5 is rotatably coupled into going out for the syringe of syringe 1
Mouthful.The opener 3 need to combine tree shrew oral cavity structure, and selection is beneficial to fixed tree shrew oral cavity, and tree shrew tooth is not damaged and oral cavity is viscous
The passivity wood materials of film, it is long generous for 10cm × 1cm × 0.5cm；The through hole 6 greater diameter than stomach tube 2mm is chiseled on opener,
Make it allow stomach tube to pass through opener and reach stomach into tree shrew oesophagus.
During gavage, the volume of the long stomach tubes of 15cm is measured first, is then opened tree shrew oral cavity with opener 3, is passed through opener
On through hole 6 will scribble the stomach tube insertion tree shrew stomach bottom of lubricant, swallow about 5cm, open flexible glue lid 7, stomach tube is inserted prior
In the sterile distilled water got ready, the situation of mispluging is determined whether, once bubble will be produced by occurring mispluging in tracheae situation water, then
The suction meter of syringe 1 determines the particle supensoid agent that volume adds the PBS or similar buffer solution of stomach tube volume to be resuspended, and is connected to stomach tube
2 exposed openends 5, medicine are pushed into the stomach of tree shrew；Then it is slow to extract stomach tube 2, complete gavage.
The present embodiment provides the advantage of tree shrew gavage device：Stomach tube 2 is made by the silica gel material of soft texture, to animal
Mucous membrane not damaged, arbitrarily changes direction and is easy to detect whether to misplug phenomenon, stomach pipe end by the openend 5 of syringe spline structure
Closing, lateral opening is easy to medicaments uniformity to enter animal stomach.
The flexible fixed tree shrew oral cavity of opener 3, makes stomach tube via through holes 6 pass through oral cavity, and reaching stomach into esophagus protects
Being smoothed out for gavage is hindered, and can avoid damaging tree shrew during gavage, accomplished simple and used
Safe ready.
After present apparatus gavage, experiment does not occur malaise symptoms with tree shrew.
