Rat topical (contamination) casting harness
Technical field
The present invention relates to a kind of rat topical (contamination) casting harness, be applicable to the fields such as pharmacology, toxicology, preclinical medicine, veterinary.
Background technology
Rat is a kind of conventional laboratory animal.When carrying out drug effect, toxicology investigation to the medicine of some topical as cutaneous permeable agent, come off for avoiding medicine, animal to the scratching of medicine-feeding part, bait and environment to the pollution of medicine-feeding part, ensure the absorption completely of medicine, often need carry out Baoding to medicine-feeding part, make it to isolate with environment.Traditional Baoding method is as wrapped up binding, adhesive tape winding etc. with gauze, and the tightness of parcel is not easily grasped, and too tightly easily affects animal activity, causes it uncomfortable; Parcel is pine too, and the adhesiveness of adhesive tape to animal hair is weak, and animal self or carry out mutually is scratched, tear etc. very easily causes again coming off of Baoding thing and medicine, thus affects the accuracy of experimental result.Meanwhile, the material in used Baoding is often disposable, also result in the wasting of resources and environmental pollution.Therefore a kind of simple and easy firmly Baoding mode is found very necessary.
Summary of the invention
The object of the present invention is to provide a kind of convenient, effective rat casting harness and Baoding method.
The invention is characterized in: this device comprises 1 main part, is made up of eyelet fabric that 2 meches 5 are made in front by length × wide=6 ~ 8cm × 6 ~ 8cm, are placed in meche 5 times by the multilamellar gauze 6 of lock seaming; 2 neck trepannings, are made up of the eyelet fabric of length × wide=4 ~ 6cm × 2 ~ 3cm, make its both sides in main part 1 side, make it form the neck trepanning of length × wide=2 ~ 3cm × 2 ~ 3cm; 3 neck cuffs, are made up of elastic cord, and long 9 ~ 12cm, through neck trepanning 2; 4 fixing bands, are made up of elastic cord by two, every bar length × wide=8 ~ 10cm × 1 ~ 3cm.
Further, above-mentioned rat topical (contamination) casting harness, is characterized in that: described neck cuff 3 both sides arrange the adhesive tape 7 that can mutually bond respectively; Side, main part 1 back side is fixed in two described fixing band 4 one end, and the other end arranges adhesive tape 7, and main part 1 back side opposite side arranges corresponding adhesive tape 7.
Further, above-mentioned rat topical (contamination) casting harness, is characterized in that: described multilamellar gauze 6 is sewn into by several pieces mono layer gauze four limits and forms together, can freely load and unload.
Baoding method of rat casting harness, is characterized in that, described Baoding method comprises the following steps:
(1) first, casting harness is placed into rat back, administration (contamination) position aimed at by casting harness front multilamellar gauze 6.
(2) secondly, passed from rat abdomen by fixing band 4 free end, the body according to rat encloses, and selects suitable bond locations, fixing band 4 free end adhesive tape 7 and main part 1 back side adhesive tape 7 is bonded together.
(3) again, by neck cuff 3 two ends respectively from the rat neck back side to front around, select correct position two ends adhesive tape 7 is bonded together.
Advantage of the present invention: structure and simple to operate, safe and effective, convenient-to-running Baoding can be carried out very easily to rat, the damage caused by conventional Baoding, the shortcoming such as handicapped can be overcome again, improve the accuracy of experimental result simultaneously, reduce the difficulty of experiment, material therefor is convenient to cleaning, sterilization simultaneously, durable in use, can Reusability.

Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing to be described in detail below:
With reference to legend, a kind of rat topical (contamination) casting harness, is characterized in that: this device comprises 1 main part, be made up of eyelet fabric, 2 meches 5 are made in front by length × wide=7cm × 7cm, and the multilamellar gauze 6 of lock seaming is placed in meche 5 times; 2 neck trepannings, are made up of eyelet fabric, length × wide=2cm × 2cm, are made on its both sides in main part 1 side; 3 neck cuffs, are made up of elastic cord, long 10cm, through neck trepanning 2; 4 fixing bands, are made up of elastic cord by two, every bar length × wide=9cm × 2cm.
Above-mentioned rat topical (contamination) casting harness, is characterized in that: described neck cuff 3 both sides arrange the adhesive tape 7 that can mutually bond respectively; Side, main part 1 back side is fixed in two described fixing band 4 one end, and the other end arranges adhesive tape, and main part 1 back side opposite side arranges corresponding adhesive tape.
Above-mentioned rat topical (contamination) casting harness, is characterized in that: described multilamellar gauze 6 is sewn into by 3 mono layer gauze four limits and forms together, can freely load and unload.
A kind of Baoding method of rat topical (contamination) casting harness, it is characterized in that, described Baoding method comprises the following steps:
Casting harness, when practicality, is first placed into rat back by the present invention, and administration (contamination) position aimed at by casting harness front multilamellar gauze 6; Secondly, passed from rat abdomen by fixing band 4 free end, the body according to rat encloses, and selects suitable bond locations, fixing band 4 free end adhesive tape 7 and main part 1 back side adhesive tape 7 is bonded together; Again, by neck cuff 3 two ends respectively from the rat neck back side to front around, select correct position two ends adhesive tape 7 is bonded together.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
