Description
Technical field
The invention belongs to the medical equipment technical field.
Background technology
The plintlet external fixation is the treatment extremity fracture, especially treats fracture of upper limb common treatment means.Use small splints fixation and must correctly grasp using priciple and method, pressure pad is placed suitably, and band can not be crossed pine or tension.Cross pine and then make fixing not firmly, fracture is shifted easily again and influences healing, and tension then easily produces the local skin pressure ulcer, and severe patient causes the limb ischemia muscular contraction, even extremity gangrene.Therefore, answer the elasticity of running check band after the small splints fixation, in time adjust clamping plate band and pressure pad.With doctor's experience and feel, this subjective impression lacks scientific basis and standardization standard, follows fully according to doctors experience and operational approach, is very easy to cause error entirely in the elasticity adjustment of clamping plate band.
At present, " a kind of fracture automatic control plintlet " of domestic Luo Zi level ground invention, it constitutes pressure switch by last item, annular contact, spring etc., design two cover pressure on-off control are reported to the police, alarm apparatus sends chimes of doom, replace feel with quantifying, but its detection sensitivity is measured demonstration accurately not as the semiconductor electrostatic capacitance pressure transducer; Zhong Yanguan, Zhong Yuquan invent " a kind of fracture small clamping plate outer of practicality ", and it mainly improves band is velcro, enclose in the velcro outside and are with graduated scale, and it just makes adjustment band elasticity be easy to grasp, but does not have measurement criteria, alarm free function; Zhao Ji prints and distributes bright " monitoring plintlet automatically ", and measurement is smart higher, and Presentation Function is arranged, but does not control function automatically, and the adjustment force value is by artificial.
Summary of the invention
The objective of the invention is:
A kind of automatic medical constant-force small splint is provided, and it utilizes aerating and exhaust device to regulate the suffered pressure of fracture automatically, under situation about participating in the doctor hardly, the force value of patient's fracture is maintained near the optimal value.Break down when power voltage insufficient or clamping plate and near adjusting less than optimal value the time, can carry out sound and light alarm according to different states.
Technical scheme of the present invention is:
Air bag is connected with aerating device, means of deflation and gas pressure intensity acquisition module by air hose, gas pressure intensity acquisition module frequency output terminal is connected with the enumerator input of microcontroller, the delivery outlet of microcontroller is connected with the control input end of aerating device and means of deflation respectively, the keyboard interface of microcontroller is connected with function keyboard, and the delivery outlet of microcontroller is connected with LCD display module control input end.
