Manual work pattern: by inflator 2 with room temperature continuous service after-5 ℃ to 26 ℃ air heating is promoted to 44 ℃ of high temperature or 38 ℃ of middle temperature or is incubated a kind of in 32 ℃ of three kinds of temperature, and can arbitrarily switch, simultaneously, relevant tutorial light is bright under the manual work pattern;
The fine setting mode of operation: the fine setting mode of operation is finely tuned air temperature based on manual work pattern, every button once heat up or the cooling scope at 0.5 ℃, in addition, for guaranteeing the patient comfort, when being incubated 32 ℃, can only regulate intensification, can not regulate cooling, when 44 ℃ of high temperature, regulate at most and be warming up to 47 ℃;
Secure operating mode: at each mode of operation run duration, when temperature reached 52 ℃, buzzing was reported to the police, and the flicker of temperature anomaly tutorial light can't recover normal after 30 seconds, then shutdown by force; When temperature was lower than 29 ℃, buzzing was reported to the police, and the flicker of temperature anomaly tutorial light can't recover normal after 30 seconds, then shutdown by force;
Distant control function pattern: can between automatic operation mode and manual work pattern, carry out remote control and switch, the remote control that can carry out 44 ℃ of manual work pattern high temperature, 38 ℃ of middle temperature and be incubated between 32 ℃ is switched, can carry out the remote control fine setting to air temperature, whenever by a remote keying or when accepting remote controller signal, inflator 2 sends the buzzing response.
Need to prove that being provided with of first auxiliary flute 9, second auxiliary flute, 80 numbers can select be adopted according to actual conditions, and between each first auxiliary flute 9, whether be provided with projection between each second auxiliary flute 80 and can select to adopt according to actual conditions; The quantity of silencing apparatus also can be selected to adopt according to actual conditions; The quantity of the external air cushion 1 of inflator 2 can adopt according to actual conditions, and corresponding construction needs to change certainly; Certainly, the assembly of the air pump of the embodiment of the invention or air pump, inflator, gas charging system are applied to the non-medical field, as long as principle is identical, too within embodiment of the invention protection domain.
Implement the embodiment of the invention, air cushion 1 adopts nonwovens to paste PE Foam and the flexible material made, have good heat insulation effect, the employing of PE Foam guarantees stable from beginning to end (for example, the PE Foam of 2.5 millimeters thickness of employing of the heating gained heater temperature of ejection, ambient temperature is at 15 ℃, air cushion 1 stem intake temperature is 32 ℃, and its afterbody temperature still can remain on 32 ℃), can be used for various medical procedures, wider than the prior art suitable environment, the air cushion 1 head and the tail temperature difference is littler; Adopt temperature-control circuit, when temperature increase during at 32 ℃ to 47 ℃, per 0.5 ℃ fine-tuning, temperature control fluctuation is less than ± 0.5 ℃, littler than the temperature fluctuation amplitude of prior art, temperature control is more stable; Provide an instantiation that the effect of native system is described better below, for example, if only being provided with the main wind passage structure, air pump 4 is not provided with when assisting air flue structure, intake grill 26 enters 26 ℃ air of 10 flows (rated flow), and it is not blocked in the pin hole district 65 of air cushion 1, be that main wind passage is when unblocked, air temperature arrising caused by friction amplitude in air pump 4 is 6 ℃ of (simple temperature arrising caused by friction, do not consider to generate heat in addition the heating of guide frame 22), the air that first tube 31 exports to air cushion 1 also should be 10 flows and temperature is 32 ℃ (32 ℃ are the human body preference temperature), but, when a part is stopped up by patient by the pin hole district 65 of air cushion 1, intake grill 26 may can only enter 26 ℃ air of 6 flows (less than 10 flows of nominal), the air that first tube 31 exports to air cushion 1 only is 6 flows at this moment, because a part is stopped up for a long time by patient by the pin hole district 65 of air cushion 1, air ventilation is always less than 10 flows of nominal in the main wind passage, in the time of stopping up, air temperature arrising caused by friction amplitude in air pump 4 constantly rises to 7 ℃ from 6 ℃, 8 ℃ etc., finally, the air that first tube 31 exports to air cushion 1 is that 6 flows and temperature can constantly rise to 33 ℃ from 32 ℃, 34 ℃ until about 50 ℃, like this, be provided with main wind passage and be not provided with under the situation in auxiliary air channel 4 of air pumps, the adaptable temperature range of system is narrow, and the safety of inflator 2 can not ensure; The air pump 4 of native system is provided with main wind passage structure and auxiliary air flue structure simultaneously, when a part is stopped up by patient by the pin hole district 65 of air cushion 1, because the setting of auxiliary air flue structure, still can guarantee when intake grill 26 enters 26 ℃ of 10 flows air, the air that first tube 31 exports to air cushion 1 is that 6 flows and intensification amplitude still can be controlled in about 6 ℃, guarantee that this system can use when ambient temperature is-5 ℃ to 26 ℃ (32 ℃ deduct 6 ℃), therefore, air pump 4 can balance be delivered to the air pressure of air cushion 1, air pump air flow rate size no matter, the air temperature rise is no more than 6 ℃ of normal temperature, can stablize simultaneously the air-supply air pressure of the air draft aperture of air cushion 1, faster than the prior art atmosphere temperature rising, and cost reduces greatly; Native system is in rehabilitation course, and winter particularly, the patient that local recovery or whole body are recovered has significant effect, can promote the blood circulation of heating region body part, shortens the patients ' recovery time; Native system also has the effect of highly significant simultaneously in surgical procedure, owing to adopt air cushion 1, can not influence operation, and patient is in the environment of preference temperature in the maintenance art, particularly in the situation of low temperature blood transfusion, anesthesia.
In addition, one of ordinary skill in the art will appreciate that all or part of flow process that realizes in the foregoing description method, be to instruct relevant hardware to finish by program, described program can be stored in the computer-readable recording medium, this program can comprise the flow process as the embodiment of above-mentioned each side method when carrying out.Wherein, described storage medium can be magnetic disc, CD, read-only storage memory body (Read-Only Memory, ROM) or at random store memory body (Random Access Memory, RAM) etc.
The above is the specific embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
