On.
Gas-guide tube 1 between intake solenoid valve 9 and pressure reducing valve 11 is equipped with drug-feeding tube 20, and drug-feeding tube 20 is equipped with spray
Mouth 21.When needing to be administered patient traumatic part, by drug-feeding tube 20, medical fluid is sprayed into air cushion layer 1 by nozzle 21, it is micro-
Processor 14 controls outlet solenoid valve 10 and opens, so that medical fluid, which is penetrated into patient by spongy layer 3, waits for agents area, realization is given
Medicine.The setting of entire medical splint makes it in use, without dismantling clamping plate, can be realized to be administered patient and control
It treats.Cooperate and venthole 24 is set in spongy layer 3, so that the flowing that drug can use air-flow enters spongy layer 4 by venthole,
To infiltration and patient skin surface is deposited to, realizes drug treatment to a certain extent.
The outer surface of air cushion layer 1 is equipped with venthole 22 and vent plug 23.It, can also be direct when pressure is larger in air cushion layer 1
The vent plug 23 opened on venthole 22 is depressurized.
Adding thermal resistance 7 is sheet adding thermal resistance 7.The embodiment of the present invention is using temperature sampler 5, adding thermal resistance 7 and micro-
Processor intelligent accurate temperature control carries out temperature regulation according to the heat distortion temperature needs of shape memory plate body 2, so that shape is remembered
The deformation of plate body 2 is recalled to be bonded well with human skin；And gas can also be adjusted according to the difference of winter and summer temperature
The mobility and temperature of gas in bed course 1 are conducive to rehabilitation to provide comfortable sendible temperature for patient.
In embodiments of the present invention, intake solenoid valve 9, outlet solenoid valve 10, adding thermal resistance 7 are respectively equipped on control panel
Deng switch, can also directly each component of manual setting work.
Specific implementation process of the invention are as follows:
As shown in Figs. 1-2, before using medical splint, shape memory high molecule deformation temperature is inputted by control panel 16
It can be compared by upper lower limit value, microprocessor 14 with the data that temperature sampler 5 is fed back.By the way that microprocessor 14 is arranged,
When temperature is lower than lower limit value, many-contact relay 15 controls adding thermal resistance 7 and heats, micro- when heating temperature reaches upper limit value
Processor 14, which controls many-contact relay 15, to be stopped adding thermal resistance 7 and works, at the same show on control panel 16 high-temperature prompt with
And temperature.At this point, shape memory plate body 2 is up to softening temperature and realizes softening, zipper 4 is opened immediately, and gas-guide tube 2 13 is extracted,
Separate air cushion layer 1 with splinting layer, the shape memory plate body 2 of softening can be according to the concrete condition at the bone of patient dislocation position
It is fixed, so that it is carried out the fixation of fitting skin, and be fixedly connected with clamping plate with patient by connection structure.
It is again that zipper 4 is closed after fixation, splinting layer is connected with air cushion layer 1 Deng, and by gas-guide tube 2 13 again insertable into
In spongy layer and air cushion layer.It cools to accelerate shape memory plate body 2, air inlet electromagnetism is controlled by many-contact relay 15
Valve 9 is opened, and fresh air is passed through into air cushion layer 1, and shape memory plate body 2 is accelerated to cool, and prevents scald patient skin.If
Microprocessor is set, during this, when pressure reaches the upper limit value of control panel setting in air cushion layer 1, is shown on control panel 16
Show high pressure prompt and relevant pressure, open vent plug 23 manually, gas is released, realizes pressure reduction, prevent 1 internal pressure of air cushion layer
Hidden danger caused by power is excessively high.In intake process, air pump 8 is in open state, controls intake solenoid valve 9 by microprocessor 14
Switch so that control air inlet.
In addition, gas-guide tube 1 is equipped with drug-feeding tube 20, drug-feeding tube 20 is equipped with nozzle 21, in clamping plate use process if you need to
To subjects bones' dislocation regional administration, medical liquid spraying can be entered by gas-guide tube 1 by drug-feeding tube 20 and nozzle 21, from
Entered in spongy layer 3 in air cushion layer 1 by gas-guide tube 2 13, and then infiltrated through at patient skin.It realizes without dismantling clamping plate, i.e.,
Treatment can be administered to patient.
In use process, due to the difference of season of summer and winter temperature, the optimum temperature of the body-sensing of patient is different.Summer, when outer
When boundary's temperature is higher, microprocessor 14 can be controlled by many-contact relay 15 intake solenoid valve and outlet solenoid valve 10 to
It is passed through fresh air in spongy layer 3, the air penetration of flowing enters in spongy layer 3 to misplace position to be sent to subjects bones, from
And realize cooling.Microprocessor 14 can be set when ambient temperature is lower in winter, is added by the control of many-contact relay 15
Thermal resistance 7 heats, and control panel 16 can show the temperature in air cushion layer 1, when temperature is higher (no more than shape memory plate body
2 deformation temperature), microprocessor 14, which can directly be passed through warm gas by the control outlet solenoid valve 10 of many-contact relay 15, leads
Tracheae 2 13 is conveyed into spongy layer 3, properly increases heating to realize.During this, it can be controlled and be ventilated by pressure reducing valve 11
Body flow, to guarantee that gas is heated to required temperature in air cushion layer 1.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on should all include within protection scope of the present invention.
