Abstract
The utility model discloses a digitized air pressure adjustor, which improves the adjusting precision of current medical equipment requiring air pressure adjustment. The digitized air pressure adjustor provided by the utility model comprises an air pressure value input part, a microcontroller, a DA (Digital to Analogue) conversion circuit, a programmable current source and a digital proportional valve connected orderly. The digital proportional valve is connected with an air pressure part of a shock wave therapeutic apparatus and is respectively connected with an air compressor, a circuit control panel and a mainframe box of the shock wave therapeutic apparatus.
Description
Technical field
This utility model is related to the armarium of band source of the gas, refers in particular to the barometric control unit that is applied in a kind of shock wave treatment appearance in rehabilitation, the healthcare field.
Background technology
At present, source of the gas is used quite extensive at medical field, and a lot of armarium all have the air pressure of use to reach its function corresponding.And stable, that precision is high, adjustable air pressure provides strong assurance for this type of armarium.But in the equipment in current market, the mode of regulating air pressure is main with mechanical type basically still, can only reach a fuzzy control, and lack the operation interface of man-machine interaction.
The utility model content
In order to improve the existing degree of regulation that needs the armarium of adjusting air pressure, this utility model provides a kind of digital pneumatic adjusting device.
The technical scheme that this utility model adopted is: this digital activating QI pressure regulator; Comprise the atmospheric pressure value input block, microcontroller, DA change-over circuit, programmable current source and the digital proportional valve that connect successively; Wherein the digital proportional valve is connected with the air pressure parts of shock wave treatment appearance, and the digital proportional valve is connected with air compressor, circuit control panel and the mainframe box of shock wave treatment appearance respectively.
Said atmospheric pressure value input block is a liquid crystal touch screen.
Said programmable current source is a constant-current source able to programme.
Above-mentioned digital pneumatic adjusting device further comprises the amplifying circuit that is connected between said DA change-over circuit and the programmable current source.The signal of DA change-over circuit output after amplifying circuit amplifies, the size of current of re-adjustment programmable current source.
The principle of this utility model is with the control of Air Compressor through microcontroller, produces the required air pressure of user, and the pulsed sound that is produced by microprocessor controls converts height ballistic shock wave accurately to; Utilize the distinctive frequency of instrument; Location through impact gun treatment head and migration play the dysfunction of improving Severe Pain point institute influence area, the metabolite that decomposition is accumulated in human body Severe Pain point; Stimulate affected regional muscle group, reach lenitive therapeutic effect.
Compared with prior art, the beneficial effect of this utility model is: by man machine interface input demand, through microcontroller circuit is got into control, thereby can in the 1bar-6bar scope, regulate the high accuracy air pressure that resolution is 0.1bar; And pressure feedback AD value that can be through real-time monitoring ratio regulate pressure, the source of the gas of accurate and stable pressure is provided for armarium well.Source of the gas safety to being defeated by armarium provides guarantee, stablizes accurate source of the gas and is beneficial to treatment, and the man machine interface more convenient operation of hommization is practical.
Description of drawings
Fig. 1 is the hardware principle block diagram of this utility model;
Fig. 2 is system's connection layout that this utility model is applied to the shock wave treatment appearance;
Fig. 3 is the flow chart of air pressure adjustment.
The specific embodiment
Below in conjunction with instance and accompanying drawing this utility model is described in further detail, but the embodiment of this utility model is not limited thereto.
Embodiment
As shown in Figure 1; This utility model comprises liquid crystal touch screen, microcontroller (MCU) S3C2440 chip, DA change-over circuit, amplifying circuit, constant-current source able to programme and the digital proportional valve that connects successively, and wherein the digital proportional valve is connected with the air pressure parts of shock wave treatment appearance.
Referring to Fig. 2, the shock wave treatment appearance generally comprises air compressor 1, mainframe box 5, circuit control panel 3 and impact gun 6.When this utility model was applied to the shock wave treatment appearance, proportioning valve 2 was connected with air compressor 1, circuit control panel 3 and mainframe box 5 respectively, and liquid crystal touch screen 4 is connected between mainframe box 5 and the circuit control panel 3.
The user directly regulates pneumatic parameter through touch screen, constant-current source able to programme is regulated by the DA change-over circuit through microprocessor controls output digital signal, thereby the purpose that the size of current of proportioning valve reaches adjusting air pressure size is transported in control.Referring to Fig. 3; The process of this utility model air pressure adjustment is mainly following: when treatment unlatching flag bit is 1; The user can pass through touch screen input air pressure parameter; If the atmospheric pressure value of air pressure parts feedbacks conforms to the pneumatic parameter that touch screen is imported, then open level appendix electromagnetic valve behind the proportioning valve, carry out the adjusting of DA signal controlling; If the atmospheric pressure value of air pressure parts feedbacks does not conform to the pneumatic parameter that touch screen is imported, then adjust DA value, just open grade appendix electromagnetic valve behind the proportioning valve then, carry out the adjusting of DA signal controlling subsequently again.When treatment is opened flag bit and is not 1, close level appendix electromagnetic valve behind the proportioning valve.
The foregoing description is this utility model preferred implementation; But the embodiment of this utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of this utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of this utility model.
