Specific embodiment
With reference to figure 1-5, can be clear that the pump for negative pressure wound treating system 10.This system 10 comprises the pump 11 that is installed in the pump case 12, and pump 11 is used for extracting liquid and secretions from negative pressure binder 34 from vacuum ports 13 evacuation, and this will carry out detailed discussion below.Pump case 12 has display screen 15 and control knob 16-19, is used for the operation of primer pump 11 and the function of testing pump.The end face of pump case 12 is formed with bayonet lock 14, so that tank 20 operationally remains on the pump case in the handshaking procedures with pump case, this will be described in detail hereinafter.In an embodiment, control knob 16-19 can provide the operation control for pump 10.Control knob 16 can be used for arranging the operating pressure of pump 10.Control knob 17 can be used for opening or closing pump 10, starts or stops negative pressure treatment.Control knob 18 can limit the method for operation, such as continuously operation or intermittent duty of pump 10.Gauge tap 19 can be used for opening and closing electronic equipment, needs before can operating other control knobs 16-18 to these electronic device power supplies.
Because need vacuum ports 13 in the 26 interior connections of receptor port, to guarantee proper operation negative pressure wound treating system 10, so pump case 12 has optical pickocff 30, be used for infrared guldance to the reflector 33 that is installed on the tank 20.If reflector 33 is correct the aligning not, namely perpendicular to optical pickocff 30, then infrared light beam will can not be reflected back in the infrared optics sensor 30.Pump 11 is operably connected to optical pickocff 30, thereby the reflected signal that need to receive reflector 33 is to activate pump 11.Preferably, optical pickocff 30 will initiate a message at display screen 15, warn user tank 20 to aim at or the incorrect pump 11 of aiming at.
As shown in Figure 5, in case tank 20 correctly is fixed on the pump case 12, pump 11 just can freely operate, and by with the vacuum ports 13 of receptor port 26 engagement, in tank 20 interior generation vacuum, and this vacuum is applied to the ingress port 36 that is connected to tank 20 and the conduit 35 that extends to negative pressure binder 34 conversely.Liquid and secretions are drawn in the tank 20 by conduit 35, and drop to tank 20 bottoms.Preferably, use the hydrophobic filter (not shown) in the inboard of receptor port 26, enter in the pump 11 by vacuum ports 13 to prevent liquid and secretions.
As seeing among Fig. 6, from the combined signal of filling sensor 38 and inclination sensor 39, with the operation of control pump 11.When tank is oriented in the upright position, negative pressure treatment system 10, specifically pump 11 and tank 20, the most efficiently operation.Therefore, when tank 20 did not have in the upright position, it is incorrect that user need to be apprised of direction, so that user can be adjusted the direction of tank 20.Preferably, inclination sensor 39 will be determined the angle of inclination, but will have certain deviation with respect to entirely accurate.For example, be accredited as the vertical direction that tank 20 can comprise the positive and negative several years in the vertical direction.
As shown in Figure 6, program 40 originates in interrogation function, in order to know the step 41 whether inclination sensor 39 activates.If inclination sensor 39 does not activate, then in the next one inquiry of step 42, determine whether filling sensor 38 activates.If filling sensor does not activate, then the operation of pump 11 will be such as predetermined continuation.If filling sensor 38 activates in step 42, program will postpone 12 seconds, then guarantee that in step 43 filling sensor 38 is not activated by the splashing of liquid in the tank 20, and the liquid that splashes can cause false alarm.After the delay circuit time expired, whether program 40 will change at the state of step 43 inquiry filling sensor 38 or inclination sensor 39.If determine there is not change of state in step 43, then then pump 11 automatically cuts out in step 45, because tank 20 is full of.If change at step 43 state, then start again in step 41 program.
If in step 41, inclination sensor 39 has activated, and then program delay activates 8 seconds, prevents the movement owing to tank 20, and liquid splash sends rub-out signal to filling sensor 38.Then in step 44, whether program inquiry inclination sensor 38 states change.If change at step 44 inclination sensor 39 states, then program is returned step 41 and is inquired whether inclination sensor 39 activates.If the answer in step 44 pair inquiry is negated that then whether program 40 activates to judge filling sensor 38 at step 46 inquiry filling sensor 38.If filling sensor 38 does not activate, then program triggers alarm in step 47, preferably includes audition and visual alarm, notifies user to redirect tank 20, suspends simultaneously the operation of pump until tank turns back to vertical direction.
Then program 40 turns back to step 44, judges whether the state of inclination sensor 39 changes.Only in step 44, the state of inclination sensor 39 changes, just can cut off alarm, and pump just can resume operation.If activated at step 46 filling sensor 38, then also can trigger alarm and suspend the operation of pump 11.If in step 49, the state of filling sensor has changed 60 seconds, then program is returned step 41, determines whether inclination sensor 38 remains activation.If all activate at step 49 filling sensor 38 and inclination sensor 39, then program will be at step 45 autoshutdown pump 11.
With reference now to the sketch map of control system among Fig. 7 50,, those skilled in the art can see the input that microprocessor 51 receives from filling sensor 38 and inclination sensor 39, with the in the manner described above continuous operation of control pump 11.In addition, optical pickocff 30 is connected to microprocessor 51, comes the initial start of control pump 11.Do not confirm that from the signal of optical pickocff 30 microprocessor 51 can not allow pump 11 to bring into operation.Microprocessor 51 is also accepted the signal from pressure transducer 55, to monitor the negative pressure that applies by vacuum ports 13.If pressure significantly rises or descends, then pump 11 is out of service, and provides information by display screen 15, informs user pressure existing problems.Pressure existing problems may be by pump 11, to insert conduit 35 operations wrong, and perhaps tank 20 overflows or the fault of other things causes.Provide the visual displays such as alarm or error message to user by LCD display 15, alarm or the signal of audition is provided to user by the buzzer 59 that is operably connected to microprocessor 51 simultaneously.
All critical components in this system 10 are all controlled in such a manner by the software that is stored in the microprocessor 51, that is, each parts is only just connected when these parts of action need of negative pressure wound treating system 10 and operated.Valve 53 operationally links to each other to open and close when needing pump 11 to improve the pressure-reduction level that puts on tank 20 with pump 11.Therefore, valve 53 is only just opened when the action need of the pump 11 that is limited by pressure transducer 55.In addition, not all sensor circuit all activated in the operating period of system 10, except this circuit of action need of nonsystematic 10.For example, the circuit that is used for optical pickocff 30 only activates when tank 20 breaks away from pump case 12.Filling sensor 38 expression tanks 20 are used for the circuit of inclination sensor 39 until be it seems closes when being full of.Then, inclination sensor 39 and filling sensor 38 operate as shown in Figure 6.LCD display 15 can be closed, unless when microprocessor 51 is determined to send the message of error message for example to user, unless or user is selecting one of control knob 16-18 to adjust or start during the inquiry system.
Another benefit of closing operation for negative pressure wound treating system 10 and be not fully necessary parts is that the operation of system 10 is quieter.By operating pumps 11 off and on, the overall noise of pump 11 is starkly lower than the pump 11 of continued operation.In addition, close critical component and inessential circuit has also reduced noise.Therefore, the power saving function of microprocessor 51 will provide more quiet operating system 10.
The application's invention has above been described with basic embodiment or specific embodiment.Although the present invention sets forth by preferred embodiment, the various alternative distortion known to those skilled in the art is also in the scope of the present disclosure.
