Description
(1) technical field
This utility model relates to a kind of artificial limb temperature-adjusting device, particularly a kind of passive miniature temperature-adjusting device for adsorption-type artificial leg receptive cavity.
(2) background technology
Artificial limb also claims " artifucial limb ", be for the artificial limb of amputee's use with compensatory damaged limb part function, two kinds of upper extremity prosthesis and artificial legs are arranged, wherein artificial leg comprises prosthetic socket and artificial limb connecting rod, many with aluminium, timber, leather, plastic or other material making, sealing is relatively good, and when wearing summer, lower limb is perspired easily, volatilization is not come out again, cause in the prosthetic socket temperature too high, make and wear the artificial limb person is very painful, many times all repel and wear artificial limb.
(3) summary of the invention
This utility model provides a kind of passive miniature temperature-adjusting device that is used for adsorption-type artificial leg receptive cavity that reduces temperature in the prosthetic socket in order to remedy the defective of prior art.
This utility model is achieved by the following technical solution:
The passive miniature temperature-adjusting device that is used for adsorption-type artificial leg receptive cavity, it is characterized in that: it comprises the compressing gasbag with vaporizer, compressor function that is positioned at prosthetic socket and is positioned at the outer high pressure fluid reservoir with liquid storage, heat sinking function of prosthetic socket, connect by two line seal between described compressing gasbag and the high pressure fluid reservoir, wherein a pipeline is provided with the supercharging valve sets, article one, pipeline be provided with have throttling, the pressure loading valve group of non-return, expansion function, described high pressure fluid reservoir is provided with liquid injection port and air vent.Wherein said pipeline is pressure pipe.
The beneficial effects of the utility model are:
This utility model is by injecting coolant in fluid reservoir, then by having filtration, hold back, spraying into compressing gasbag after the pressure loading valve group of non-return, expansion function, when lifting, artificial limb can produce low pressure in the compressing gasbag, coolant is gasified in compressing gasbag, owing to be the process of a heat absorption from the liquid state to the gaseous state, so gasification can absorb the heat in the prosthetic socket; When artificial limb fell, the gas when compressing gasbag is squeezed in the compressing gasbag was pressed in the high pressure fluid reservoir by the supercharging valve sets, and gas liquefies after meeting high pressure.Just can drive whole device when the such artificial limb of patient wear is alternately walked is discharged into the heat in the prosthetic socket outside the prosthetic socket circularly, reduce the temperature in the prosthetic socket, make the temperature that remains a suitable human body in the prosthetic socket, the patient is felt comfortably cool.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Fig. 1 is main TV structure sketch map of the present utility model;
Fig. 2 makes the fundamental diagram of coolant gasification for compressing gasbag expands;
Fig. 3 arranges the into fundamental diagram of high pressure fluid reservoir for the compressing gasbag pressurized with gas in the compressing gasbag.
Among the figure, 1 prosthetic socket, 2 artificial limb connecting rods, 3 compressing gasbags, 4 high pressure fluid reservoirs, 5 pipelines, 6 pressure loading valve groups, 7 supercharging valve sets, 8 liquid injection port, 9 air vents.
(5) specific embodiment
Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1, the passive miniature temperature-adjusting device that should be used for adsorption-type artificial leg receptive cavity, it comprises the compressing gasbag 3 with vaporizer, compressor function that is positioned at prosthetic socket 1 and is positioned at the prosthetic socket 1 high pressure fluid reservoir 4 with liquid storage, heat sinking function outward, compressing gasbag 3 is positioned at the bottom of prosthetic socket 1, when the patient wear prosthetic walking, human body will push compressing gasbag 3; High pressure fluid reservoir 4 preferably is positioned at the side of prosthetic socket 1 below, artificial limb connecting rod 2, be tightly connected by two pipelines 5 between compressing gasbag 3 and the high pressure fluid reservoir 4, these two pipelines 5 are preferably pressure pipe, wherein a pipeline 5 is provided with supercharging valve sets 7, article one, pipeline 5 is provided with pressure loading valve group 6, and pressure loading valve group 6 has the function of throttling, non-return, expansion; Be provided with fluid injection 8 and air vent 9 at high pressure fluid reservoir 4, liquid injection port 8 is used for injecting coolant, and air vent 9 is used for regulating temperature and emptying in winter coolant.
Work process of the present utility model is as follows: inject coolant by liquid injection port 8 in high pressure fluid reservoir 4, when this utility model walking of patient wear, as shown in Figure 2, artificial limb lifts, compressing gasbag 3 is produced negative pressure, this moment, supercharging valve sets 7 was in closed condition and pressure loading valve group 6 is in opening, coolant in the high pressure fluid reservoir 4 is injected compressing gasbag 3 by pressure loading valve group 6, compressing gasbag 3 expands, coolant is met low pressure gasifying, owing to be the process of a heat absorption from the liquid state to the gaseous state, so this gasification can absorb the heat in the prosthetic socket 1; When artificial limb falls, as shown in Figure 3, compressing gasbag 3 is subjected to the extruding of human body, pressure loading valve group 6 is in closed condition at this moment, supercharging valve sets 7 is in opening, vaporized coolant in the compressing gasbag 3 enters high pressure fluid reservoir 4 by supercharging valve sets 7, coolant is vaporized, heat is along with coolant also is brought in the high pressure fluid reservoir 4, because high pressure fluid reservoir 4 has heat sinking function, so these heats are distributed, and the temperature of coolant also lowers, when artificial limb lifts next time, carry out circulation next time again, so go round and begin again, the heat in the prosthetic socket 1 is constantly discharged, can make the temperature of the suitable human body of temperature maintenance in the prosthetic socket 1, the patient is felt comfortably cool.Can carry out thermoregulation according to ambient temperature and body adaptation temperature by air vent 9, pass through air vent 9 winter with the coolant emptying.
