(2) as shown in Fig. 5,6,10, in negative pressure drainage mode:

A, according to preset drainage initial time, the working condition that controller adjusts component to drainage regulates and controls, promotes The output of carry out fluid and the fluid of 18 alternate cycles of drainage tube suck, and make the fluid from flowing backward in drainage tube 18, that is, it is fixed to realize Shi Yinliu；

B, in drainage process, controller adjusts the working condition that drainage adjusts component according to real-time drainage speed, i.e., The operating status for adjusting fluid output with fluid sucking, finally makes real-time drainage speed tend to be equal with preset drainage speed, Realize constant speed drainage, the operating status that fluid output is sucked with fluid includes the start and stop of fluid output and fluid sucking, continues Time, working frequency；

C, in drainage process, controller calculates this time drainage starting to current single achieved in real time and drains in real time Amount, after the real-time drainage flow of single reaches preset single drainage flow, controller will adjust the position of longitudinal briquetting 5, make longitudinal direction Briquetting 5 squeezes the exit for setting drainage tube 18 in pipe gap to blocking state, and two lateral briquettings 9 are then adjusted to initial bit It sets, this time drainage terminates at this time and drainage tube 18 is squeezed by longitudinal briquetting 5 and keeps off state at this time, that is, realizes and quantitatively draw Stream.

In negative pressure drainage mode, after drainage, controller adjusts 5 position of longitudinal briquetting, makes it that will set pipe gap The exit of middle drainage tube 18 is squeezed to blocking state, and two lateral briquettings 9 are then adjusted to initial position again；The technical characteristic Be intended, negative pressure drainage pause or at the end of, the exit of drainage tube 18 is squeezed to blocking state by longitudinal briquetting 5 And the hydrops in drainage tube 18 is avoided to flow back, and lateral briquetting 9 does not constitute drainage tube 18 and squeezes, so that setting drawing in pipe gap Flow tube 18 can restore i.e. cylindric to original state automatically, avoid being chronically at collapsed state and elasticity is greatly reduced, and guarantee subsequent negative Pressure drainage can stablize progress.

Referring to shown in Fig. 5,6,10, this multi-functional drainage controlling device is carrying out negative pressure drainage process in clinical use In, drainage adjusts component under the regulation of controller, makes longitudinal briquetting 5 and two lateral briquettings 9 by specific rule to drainage tube 18 implement corresponding squeezing action, realize negative pressure drainage and can regulate and control to negative pressure drainage state；During negative pressure drainage, The lateral briquetting 9 of longitudinal briquetting 5, two and the structure that the drainage tube 18 in pipe gap is constituted is set positioned at two can be considered a volume Pump, working principle is very similar with diaphragm pump, is based on this, and drainage adjusting component can be realized negative pressure under the regulation of controller and draw It flows and negative pressure drainage state can be controlled accordingly, the specific working principle is as follows:

Fluid output:

As shown in figure 5, longitudinal briquetting 5, which is located at, squeezes 18 exit of drainage tube to resistance after the completion of a negative pressure sucking The position of disconnected state, two lateral briquettings 9 are then located at initial position；When 5 position of the longitudinal briquetting of controller adjusting, make longitudinal briquetting 5 The leading-in end for setting drainage tube 18 in pipe gap is squeezed set at this time to blocking state the exit of drainage tube 18 in pipe gap then with Drainage bag 19 is connected to, and when two lateral briquettings 9 carry out separate, is set the drainage tube 18 in pipe gap and is squeezed respectively by two lateral briquettings 9 Pressure and volume changes, internal hydrops to 19 direction of drainage bag flow, be achieved in fluid output；Longitudinal briquetting 5 by During exit is moved to introducing extreme direction, there are drawing between a leading-in end, exit and leading-in end and exit Flow tube 18 is in the unimpeded period of on state, but in general, all existing substantially in existing common drainage component prevents The one-way valve mechanism of fluid reflux thus prevents the fluid reflux in unimpeded period drainage tube 18 above-mentioned；Backward and Speech, even if drainage component does not have the function of making one-directional fluid flow, but can be by drainage tube 18 and 19 junction of drainage bag The mode for adding existing one-way valve mechanism easily is realized the technical requirements for preventing fluid reflux；

Fluid sucking:

As shown in fig. 6, setting in pipe gap and draining after drainage adjusting component promotes drainage tube 18 to complete a fluid output The leading-in end of pipe 18 is in blocking state, and exit is then in the conductive state, at the drainage tube 18 between leading-in end and exit In the state of being crushed；When 5 position of the longitudinal briquetting of controller adjusting, it is in the exit for setting drainage tube 18 in pipe gap and blocks shape State, leading-in end is then in the conductive state and communicates with human body, after two lateral briquettings 9 are close and are reset to initial position, originally The drainage tube 18 flattened by two lateral briquettings 9 between exit and leading-in end can by elasticity possessed by itself and by Gradually revert to cylindrical shape, so that 18 front end of drainage tube is generated negative pressure with the increase of volume, people's intracorporal hydrops sucking drawn In flow tube 18, i.e. realization fluid sucking；

The realization of negative pressure drainage:

It is when drainage adjusts component, and the alternate progress fluid output of drainage tube 18 is promoted to suck with fluid, i.e., certifiable to drain Fluid in pipe 18 flows backward always, i.e. realization negative pressure drainage；

(1) as shown in Figure 23,24, when carrying out fluid output and fluid is hydrops, hydrops pushes up floating ball 63 and passes through Inlet opening 61 enters in column chamber 64, and floating ball 63 rises with increasing for hydrops in column chamber 64, and the hydrops in column chamber 64 is through drainage hole 67 discharge, finally flow among drainage bag, due to venthole 66 be higher than drainage hole 67, therefore hydrops can't be through venthole 66 outside It overflows；After completing a fluid output, since drainage hole 67 is communicated with venthole 66, the hydrops in valve chamber be will continue to drainage bag Middle flowing, floating ball 63 sinks with the reduction of hydrops in column chamber 64, such as product when hydrops is flowed back in drainage tube, in column chamber 64 Liquid disappears, so that floating ball 63 sinks down into 64 bottom of column chamber and blocks inlet opening 61, thus prevents the hydrops reflux in drainage tube；

(2) when carrying out fluid output and fluid is air, air push floating ball 63 rises and enters column through inlet opening 61 In chamber 64, and after through the gap between floating ball 63 and column chamber 64 continue up flowing, be ultimately discharged into the external world, as on drainage bag itself Equipped with gas exhaust piping, then the partial air in column chamber 64 can also drain into drainage bag through drainage hole 67, and finally through drainage bag Gas exhaust piping drains into the external world；After completing the output of fluid, floating ball 63 by self weight sink down into 64 bottom of column chamber and by feed liquor Hole 61 blocks, and thus prevents the air return in drainage tube；

After this unidirectional out splice going splice uses above-mentioned design, with the unidirectional output characteristics of fluid, negative pressure drainage can be met With the technical need of normal pressure drainage；In addition to this, since floating ball 63 may float on hydrops, therefore its density is smaller, turns it on Required pressure very little, i.e. operating pressure is low, will not flow to hydrops in drainage process and generate excessive obstruction, especially exist In normal pressure drainage, the adjustable extent of drainage speed can be improved to greatest extent；

At the same time, because this unidirectional out splice going splice is reset to off state and is that the gravity based on floating ball 63 is realized, and Reset force is provided without additional elastic component, is not only simple in structure, also ensures the stabilization of unidirectional out splice going splice work Property, improve working life.
