Specific embodiment
Specific embodiment of the invention is described below in detail, the example of specific embodiment is shown in the drawings, Wherein identical label represents same or analogous element from start to finish.Below with reference to the accompanying drawings the tool for describing Body embodiment is exemplary, it is intended to explains the present invention, and can not be construed to a kind of limit of the invention System.
Fig. 1 shows a kind of negative pressure drainage treatment system, and it mainly includes:Wound sucker 1, it is used for Negative pressure source 5, hydrops tank 3, drainage tube 2,6 and the negative pressure drainage regulator 4 of negative pressure are provided, Wherein, it is connected by drainage tube 6 between wound sucker 1 and hydrops tank 3, hydrops tank 3 and negative pressure source It is connected by drainage tube 2 between 5, and negative pressure drainage regulator 4 is arranged on hydrops tank 3 and negative pressure At drainage tube 2 between source 5.
According to the present invention, the Main Function of negative pressure drainage regulator 4 is to provide user institute as needed The negative pressure value for needing, and be required between continuous constant pressure pattern and interruption pressure regulation pattern according to user Switching running.As shown in Fig. 2 negative pressure drainage regulator 4 mainly includes the He of pressure sensor 450 Valve module, wherein, pressure sensor 450 is arranged on drainage tube 2 and draws for sensing and feeding back The pressure value of gas in flow tube 2, and valve module is then used for being selected in continuous constant pressure according to user Switch between pattern and interruption pressure regulation pattern, wherein, the pressure in drainage tube 2 under continuous constant pressure pattern Force value keeps continuous constant, and is being interrupted the pressure value under pressure regulation pattern in drainage tube 2 in the scheduled time High negative pressure value and lower negative pressure value between circulate.
According to embodiments of the present invention, valve module includes mechanical pressure regulator valve 410, the and of the first magnetic valve 420 Second magnetic valve 430.Specifically, mechanical pressure regulator valve 410 is arranged on drainage tube 2 near negative pressure source 3 Side, for presetting a safety negative-pressure value.For example, one can be set by mechanical pressure regulator valve 410 Individual maximum safety negative-pressure value, i.e., the peak suction value that patient people's physical efficiency is born is any when occurring to ensure Under abnormal conditions, the negative pressure value that pressure regulator is provided all without more than this maximum safety negative-pressure value, from And effectively protect the safety of patient.Mechanical pressure regulator valve 410 can be adjusted manually.First magnetic valve 420 Drainage tube 2 is arranged near the side of hydrops tank 3, for the pressure value fed back according to pressure sensor 450 The lower negative pressure state in drainage tube 2 is realized in break-make mode;Second magnetic valve 430 is similarly disposed at and draws Flow tube 2 near the side of hydrops tank 3, for the pressure value fed back according to pressure sensor 450 with break-make side Formula realizes the high negative pressure state in drainage tube 2.Specifically, the first magnetic valve 420 is arranged on drainage tube Between mechanical pressure regulator valve 410 and pressure sensor 450 on 2;And the second magnetic valve 430 is arranged on Between the first magnetic valve 420 and pressure sensor 450 on drainage tube 2, and determined in break-make mode Whether drainage tube 2 connects with outside air.So, sense and feed back based on pressure sensor 450 Pressure value, by mechanical pressure regulator valve 410, the first magnetic valve 420 and the second magnetic valve in valve module 430 compounding practice, can cause that device is adjusted in continuous constant pressure pattern and interruption according to the selection of user Switch running between die pressing type.
According to the present invention, the workflow diagram of negative pressure drainage regulator 4 is as shown in Figure 3.First, One maximum safety negative-pressure value is set by mechanical pressure regulator valve 410.Then, carried out according to user's request Model selection.
In the case where continuous constant pressure pattern is switched to, the constant pressure value selected based on user and The pressure value of the feedback of pressure sensor 450, when the pressure value of the feedback of pressure sensor 450 is less than user Selected constant pressure value, adjusts the on off operating mode of the one 420 and the 2nd 430 magnetic valve, with from outer Boundary imports pressure value of the air up to the feedback of pressure sensor 450 equal to the constant pressure value that user selectes, So as to realize continuous constant pressure state;And the pressure value for working as the feedback of pressure sensor 450 is selected more than user Constant pressure value, adjust the one 420 and the 2nd 430 magnetic valve on off operating mode, to extract drainage Air in pipe 2 is until the pressure value of the feedback of pressure sensor 450 is equal to the constant pressure that user selectes Value, so as to realize continuous constant pressure state.Specifically, when the pressure value of the feedback of pressure sensor 450 is small In the constant pressure value that user selectes, the first magnetic valve 420 is disconnected and the second magnetic valve 430 is connected It is logical, air is imported up to pressure value that pressure sensor 450 feeds back is selected equal to user with from the external world Constant pressure value, then disconnects the second magnetic valve 430, to keep continuous constant pressure state;And work as pressure The pressure value of the feedback of sensor 450 is more than the constant pressure value that user selectes, the quilt of the first magnetic valve 420 Connection and the second magnetic valve 430 is disconnected, to extract the air in drainage tube 2 until pressure sensor The pressure value of 450 feedbacks then disconnects the first magnetic valve 420 equal to the constant pressure value that user selectes, To keep continuous constant pressure state.
And in the case where interruption pressure regulation pattern is switched to, based on the high/low negative pressure value that user selectes And the pressure value of the feedback of pressure sensor 450, when the pressure value of the feedback of pressure sensor 450 is less than The high/low negative pressure value that user selectes, adjusts the on off operating mode of the one 420 and the 2nd 430 magnetic valve, With from the external world import pressure value that air fed back up to pressure sensor 450 equal to the height that user selectes/ Lower negative pressure value, so as to realize high/low negative pressure value stable state, terminates until the in stable condition time, cuts It is changed to next pressure state;And what the pressure value for working as the feedback of pressure sensor 450 was selected more than user High/low negative pressure value, adjusts the on off operating mode of the one 420 and the 2nd 430 magnetic valve, to extract drainage Air in pipe 2 is until the pressure value of the feedback of pressure sensor 450 is high/low negative equal to what user selected Pressure value, so as to realize high/low negative pressure value stable state, terminates until the in stable condition time, switches to Next pressure state.Specifically, when the pressure value of the feedback of pressure sensor 450 is selected less than user High/low negative pressure value, the first magnetic valve 420 is disconnected and the second magnetic valve 430 is connected, with from The external world imports air until the pressure value of the feedback of pressure sensor 450 is high/low negative equal to what user selected Pressure value, then disconnects the second magnetic valve 430, to keep high/low negative pressure value stable state;And work as pressure The pressure value of the feedback of sensor 450 is more than the high/low negative pressure value that user selectes, the first magnetic valve 420 By connection, the second magnetic valve 430 is disconnected, to extract the air in drainage tube 2 until pressure sensing The pressure value of the feedback of device 450 then disconnects the first magnetic valve equal to the high/low negative pressure value that user selectes 420, to keep high/low negative pressure value stable state, so as to realize dynamic negative regulation.
