Description
Technical field
This utility model relates to a kind of pressure ulcer modeling structure of laboratory animal, belongs to technical field of experiment equipment.
Background technology
Current domestic conventional pressure ulcer modeling method mainly contains: built-in spring forces method, mechanical pressure method, magnetic force compression method, water column method and air compressor method 5 kinds, by comparative analysis: the advantage of mechanical pressure method there is pressure, shearing force and frictional force simultaneously, closer to the forming process of pressure ulcer, meet the definition of pressure ulcer; Weak point is whole modeling process need continuous narcosis, certain impact may be produced to the physiological environment of rat, built-in spring forces method and magnetic force compression method all need first by the incision of skin of laboratory animal, at subcutaneous implantation titanium plate or magnetic sheet, the inflammatory reaction of local organization may be caused like this, and water column method and air compressor method higher due to requirement for experiment condition, be not suitable for extensively being adopted by scientific research, thus adopt number of times less.
Utility model content
The purpose of this utility model is: for prior art design a kind of more easy, be easy to the pressure ulcer modeling structure that operates, realize carrying out pressure ulcer molding to animal fast, good stability and low to animal injury, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A kind of pressure ulcer modeling structure of laboratory animal, comprise base plate A, 4 support threaded rods one are vertically fixed on base plate surrounding, steel plate B is provided with directly over base plate, steel plate B is inserted by the circular hole one being arranged on its surrounding and supports on threaded rod one, support threaded rod one arranges upper and lower nut one, realize steel plate B and support the fixing of threaded rod one, rectangular opening is provided with in the middle part of steel plate B, support the rectangular opening both sides that threaded rod two is vertically fixed on steel plate B, steel plate C is inserted by circular hole two disposed thereon and supports on threaded rod two, threaded rod two arranges upper and lower nut two and realize fixing of steel plate C and threaded support bar two supporting, circular hole three is provided with and corresponding with rectangular opening in the middle part of steel plate C, bottom is provided with the depression bar of briquetting respectively by rectangular opening and circular hole three, depression bar above briquetting is provided with rectangle chuck, on depression bar above rectangle chuck, cover has spring, rectangle chuck rotates through after rectangular opening the clamping that depression bar realizes rectangle chuck and rectangular opening, spring realizes pretension between rectangle chuck and steel plate C lower surface.
In the pressure ulcer modeling structure of aforesaid a kind of laboratory animal, described support threaded rod one and the connected mode of base plate A adopt directly welds or screw thread is fixed.
In the pressure ulcer modeling structure of aforesaid a kind of laboratory animal, described support threaded rod two and the connected mode of steel plate B adopt directly welds or screw thread is fixed.
Owing to have employed technique scheme, compared with prior art, this utility model ensure laboratory animal without the need to continuous narcosis, without additional machinery damage and do not change physiological environment state under form pressure ulcer, thus avoid increasing interference factor, with the stability of Enhancement test, repeatability and ease for operation, to obtaining closer to clinical pressure ulcer model, for researcher research pressure ulcer provides a kind of easy to operate, reusable pressure ulcer animal model device for exerting.
