As shown in figure 4,14 lower end of suspension part is equipped with the hook that can be matched with 30 link of drainage bag, and in order to anti- Only relative rotation occurs for link and suspension part 14, and the hook of 14 lower end of suspension part preferentially uses lath-shaped material bending to be made；Institute Plug-in type axial stretching structure can be used in 14 upper end of suspension part and weighing 13 lower end of bar stated, and is arranged therebetween for locking The retaining mechanism of both fixed relative position.

Referring to shown in Figure 10, in this full-automatic medical drainage device, thus roll 7 is indirectly installed on centre wheel 4 Can centre wheel 4 driving under revolve, roll 7 revolve direction it is consistent with 4 direction of rotation of centre wheel and tool there are two types of form, roll Roller 7 only can just drive the fluid in drainage tube 29 to flow from the front to the back under specifically revolution direction, therefore in foregoing description A kind of direction of rotation that " forward direction " in the positive revolution of middle appearance is merely for convenience of describing and setting defines, and is by roll 7 The revolution direction definition that fluid is flowed from human body to 30 direction of drainage bag in drainage tube 29 can be driven for forward direction in process of revolution；And Since in the specific implementation process, the relative position of drainage tube 29 and roll 7 is not intended to be limited to specific one kind, roll 7 is driven Practical revolution direction required for flowing hydrops from human body to drainage bag 30 is opposite by drainage tube 29 and roll 7 Position influences, and therefore, in various embodiments, the actual steering of the positive revolution of roll 7 is not necessarily the same.

Referring to shown in Fig. 4,5,11, in this full-automatic medical drainage device, offered in setter plate 6 and 3 side wall of dimple The introduction hole 8 and lead-out groove 12 communicated；On the one hand, introduction hole 8 and lead-out groove 12 for guide drainage tube 29 more smooth into Enter annular gap and drawn from annular gap, facilitates drainage tube 29 and prolong in annular gap by ad hoc fashion progress spiral It stretches, while avoiding 29 bending part of drainage tube from forming dog leg and increasing pipe resistance；On the other hand, introduction hole 8 and 12 pairs of lead-out groove drainages Pipe 29 imposes certain fixing effect, avoids drainage tube 29 from being acted on and vibration by roll 7, improves annular gap inner drainage tube 29 The stability cooperated with roll 7；

In addition, as shown in figure 4, there are the circular in cross-section of introduction hole 8 in this full-automatic medical drainage device, and The anterior socket of lead-out groove 12 is exposed to the technical characteristic of the front side of setter plate 6, and purpose is deposited both ways, on the one hand, full Under conditions of sufficient drainage tube 29 can introduce and draw annular gap, the integrality of 3 side wall of dimple is improved, to greatest extent to protect The card rotation of roll 7 all can apply stable squeezing effect to the drainage tube 29 in annular gap with 3 side wall of dimple to any position, On the other hand, in the case where meeting foregoing advantages, drainage tube 29 and introduction hole 8, annular gap is reduced, tears a group difficulty open between lead-out groove 12 Degree.

Referring to shown in Fig. 8, in this full-automatic medical drainage device, drainage tube 29 prolongs in a spiral form in annular gap It stretches and is greater than a circle less than two circles, wherein the purpose of " being greater than a circle " is, roll 7 continues positive revolution during negative pressure drainage When, it will the successional drainage tube 29 in annular gap is implemented to squeeze, and the squeezing action that drainage tube 29 is integrally subject to is not It can be interrupted, thus can guarantee that the fluid in drainage tube 29 continues to flow backward, while avoiding fluid reflux in drainage tube 29, In purpose " less than two circles " be avoid the excessive spiral in annular gap of drainage tube 29, on the one hand avoid increasing drainage tube 29 Integral tube resistance, is on the other hand effectively reduced annular gap, the size of centre wheel 4 and roll 7 in the longitudinal direction, makes above-mentioned component Structure is more compact；

Can not set it is no, during negative pressure drainage, roll 7 continue in positive process of revolution with 29 relative position of drainage tube Variation can cause hydrops flow velocity in drainage tube 29 to generate certain variation, but the change in flow will not be too significant, has no effect on reality Border clinic drainage effect；And at the same time, it is inhomogenous to alleviate flow velocity also the means such as buffer container can be added on drainage tube 29 This problem.

Referring to shown in Fig. 9, this full-automatic medical drainage device is in clinical use, during negative pressure drainage, drainage tube 29 need to provide necessary pressure by the elasticity capacity of itself for negative pressure drainage, it is however generally that, the drainage of clinical use at present Pipe 29 all has preferable elasticity, and in the initial stage of negative pressure drainage, the elastic property of drainage tube 29 is best, can meet aforementioned negative Pressure request, but with increasing for number is extruded, the elastic property of the drainage tube 29 in annular gap can weaken, by it The peak suction that natural resiliency ability can be provided will become smaller；But it in this full-automatic medical drainage device use process, can put It is positioned below the position of patient, drainage adjusts the middle and lower part that component acts on drainage tube 29, drainage tube 29 in drainage process in addition The gravitional force of interior hydrops can alleviate required negative pressure requirements, and the required negative pressure being additionally provided is smaller in this case, i.e., Weaken 29 elasticity of the drainage tube being located in annular gap, enough negative pressure also can be still provided for negative pressure drainage.

Referring to shown in Figure 11,12, this full-automatic medical drainage device is during clinical use, drainage bag 30 and its inside The weight of hydrops is almost undertaken by suspension part 14 entirely, i.e. the intimate total weight of drainage bag 30 and its internal hydrops is finally weighed Bar 13 is transferred on weighing sensor 17, and the weight of 30 these components of drainage bag after weighing bar 13, suspension part 14 and placement exists Be in drainage process it is invariable, the weight change that thus weighing sensor 17 is sensed be entirely by drainage bag 30 product Caused by the increase of liquid, therefore controller 10 is believed according to the weight of the continuous Real-time Feedback of weighing sensor 17 in drainage process Number, hydrops weight change speed in drainage bag 30 can be calculated, i.e., real-time drainage speed can be calculated in this time Drainage starting is to hydrops accumulates weight, the i.e. real-time drainage flow of single in drainage bag 30 during this current section, therefore, control Device 10 can be drained in real time based on the weight signal of the continuous Real-time Feedback of weighing sensor 17 to calculate real-time drainage speed, single What this technical requirements of amount can be achieved on using the prior art；

It can not set no, in drainage process, drainage bag 30 is fixedly connected with 29 tail end of drainage tube, and drainage tube 29 is inevitable Meeting certain active force is generated to drainage bag 30, and as the deformation of drainage bag 30 active force above-mentioned may become Change, to have a certain impact to the data accuracy tool of real-time drainage speed and the real-time drainage flow of single；But it is full-automatic at this In medical drainage device, before clinic drainage is implemented, the height of drainage bag 30 can be adjusted by suspension part 14, makes drainage tube 29 Part between lead-out groove 12 and drainage bag 30 is in nature extended state, thus can reduce 29 lower end of drainage tube to drainage bag 30 active forces generated reduce it to influence brought by the data accuracy of real-time drainage speed and the real-time drainage flow of single.
