Description
Technical field
This utility model relates to a kind of fixture, specifically, is about a kind of Multifunction test animal eye protection and fixing device for extremity.
Background technology
In operation process, the protection of cardio-pulmonary function, all experimenters can pay attention to, but in art, eye protection is often out in the cold, especially general anesthesia animal.When general anesthesia, due to the effect of anaesthetic, the central nervous system of operation animal is suppressed, in automatism, of flaccid muscles unable, and guarding reflex effect disappears or weakens, and has substantially lost autonomous regulating power.The eyes of a lot of animals can not be independently closed, comprising self-protection afunctions such as winking reflexs.
The eyes are the windows of the mind, and animal too.A lot of experimenters, in order to ensure that surgical field of view is clear, ceaselessly increase the brightness of shadowless lamp, but have often ignored the protection to animal eyes.At general anesthesia operation, not in the patient of row eye protection, the sickness rate of corneal injury can be up to 44%.After having the transparent medical adhesive tape of the low allergy of employing to paste eyelid, eye conjunctival sac coating tetracycline eye ointment, paste eye protection embrane method or eyeshield Protection Code, these methods are all not suitable for animal again, because animal build is very little, eye is less, and circumference of eyes is hair entirely.Animal under narcotism, their eyes are in opening state, and general adhesive tape at all can not complete closed eyes, and this has just caused nearly all animal after operation that cornea damage in various degree has all occurred.Operation towel can all hide animal face, affects animal breath, and light-shading effect is not good yet.The little experimental result that affects of day photosensitiveness damage of animal eyes, greatly violates animal ethics, therefore extremely urgent to the protection of animal eyes.
Through animal experimental observation for many years, we find eye protection disappearance in art, and following complication may occur: 1. eye pressurized, causes optic nerve anoxia, visual deterioration.2. exposure keratitis.3. ophthalmic chemical burn etc.For fear of the generation of above complication, we protect by the eye to animal in operation, have designed a kind of Multifunction test animal eye protection device.
And multi-function animal limbs fixing device, with former fixture ratio, this device uses mechanics and pulley principle, more meets the anatomical physiology construction features of laboratory animal.Animal fixing device in the past, often only talks fixingly, has but ignored extremity protection to laboratory animal and the exposure of surgical field of view.Concerning an operation, exposing clear is the strong guarantee of successful surgery.In science and technology today in the ban, the foundation of laboratory animal disease model can provide strong support for follow-up a large amount of disease research and preventing and controlling.In biomedical research, we usually depend on and come confirmatory experiment hypothesis and clinical hypothesis with animal model, to be more effectively familiar with generation, law of development and the research prophylactico-therapeutic measures of human diseases.Therefore, use animal model to become in modern biomedical research a very important experimental technique and means.
At present domestic to the protection of laboratory animal eyes still in the budding stage, not yet cause the enough attention of each side; A lot of experiments all have problemss, and in the time building single experimental animal model, we have often additionally built our undesired model: day photosensitiveness ophthalmia.The deviation that this will inevitably cause experimental data, has influence on the accuracy of experimental data, does not more meet animal ethics.Based on above-mentioned consideration, we have designed this kind of laboratory animal eye protection device just, make up the blank in this field; On the other hand, former laboratory animal limbs fixing device all rests on the aspect of " fixing ", has often ignored deriving on immobilizing foundation.Do not increasing under the prerequisite of operating difficulty, what As soon as possible Promising Policy was performed the operation need to be that we really want.

The use of a kind of Multifunction test animal eye protection of this utility model and fixing device for extremity: after laboratory animal anesthesia success; animal head is deployed in protector 1; laboratory animal neck is placed in to rear plate opening 151 times; animal right fore is placed in to the first side plate open front 211 times; right hind is placed in the first side plate after-opening 212 times; left fore is placed in the second side plate open front 221 times, and left hind is placed in the second side plate after-opening 222 times.
Embodiment 2
Choose some of 8-10 week SD rats, body weight 200-250 gram, arranges three groups at random: 1. eye protector group is installed; 2. be exposed to group under high light; 3. the SD rat under usual state.Eye protector is selected: length=6cm, 4cm, 5cm; The about 2cm of height that adjusts arch, avoids oppressing trachea, is unlikely to have too many light to enter dark lattice simultaneously.After anaesthetizing successfully with 3% pentobarbital sodium, shadowless lamp vertical irradiation rat head 2 hours, after rat revives, the eye situation of more different group rats.
Result: rat under the rat eye of eye protector group and state is usually installed without significant difference, and it is dry and astringent to be exposed to rat eyes under high light, opens not open, movable slow.
Fixing device for extremity after anesthesia: divide three groups: 1. fixing device for extremity group; 2. limbs rubber band binding group; 3. do not do any processed group.Trapezoidal fixing device for extremity size: upper wide: lower wide=4cm:10cm; Ladder high=10cm; Observe animal limb ischemia and active situation in art.
Result: fixing device for extremity and rubber band binding group are installed in art and all do not occur obviously large mobility, postoperative rubber band binding group extremity are blue, and peripheral circulation is poor, and limb temperature lowers, visible significantly rubber band vestige still after 2 hours, animal activity scope is obviously dwindled.
Lifting hook device and the comparison of abdominal part automatic dilator in art, the former is obviously more stable, firm, although both operating times are similar, the scope that abdominal part dilator exposes is significantly less than self-retractor, and what carry out due to us is intestinal surgery model, abdominal part dilator can be used reluctantly, if carry out liver or stomach operation model, abdominal part dilator cannot expose operating field so, and automatic drag hook device can compensate its defect completely.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of this utility model method; can also make some improvement and supplement, these improvement and supplement and also should be considered as protection domain of the present utility model.
