Herein, the downstream is a statement relative to the flow direction of fluid, in one embodiment, the stream The flow direction of body is originated from fluid source, via the extrusion infusing pipeline system flow to target such as patient.The phase in the downstream Opposite direction is upstream.

An object of the present invention is to need to detect whether that upstream occlusion occurs.The upstream occlusion refers to drive in fluid During device drives the flow downstream flowing in the extrusion infusing pipeline system, occur in the pipeline of test point upstream Occlusion event.Such as common upstream occlusion point can occur in the pipeline of valve system 151 and its upstream.

In order to realize the purpose of detection upstream occlusion of the present invention, in an embodiment of the present invention, it is proposed that A kind of upstream occlusion detection means.Fig. 3 is a kind of fluid control devices of the present invention containing upstream occlusion detection means Schematic diagram.The upstream occlusion detection means, which is applied, is driving what the fluid in soft pipeline was flowed with fluid drive apparatus In fluid control devices.Fluid control devices described in Fig. 3 are increased on the basis of fluid control devices described in Fig. 1 and Fig. 2 Upstream detection device.The upstream occlusion detection means mainly includes：Protrusion means 31, raised respective sensor 32 and Identified upstream module 33.

The particular location of the protrusion means 31 is characterized in：When the protrusion means 31 are in position, and described soft Matter pipeline 152 is under installment state, and the first side of 301 pairs of the convex top soft pipeline 152 of the protrusion means implements to support Pressure, the first side of the soft pipeline 152 is set to produce corresponding bend at the convex top 301.The protrusion means are in shape in place State refers to that fluid control devices are in the state of normal work on the whole.Why say the position of protrusion means, be because The protrusion means can be fixed on the housing of fluid control devices in one embodiment, embodiment as shown in Figure 3； In further embodiment, the protrusion means can also be with the fluid control devices split settings, i.e. the protrusion means can be with It is arranged on the lid of the fluid control devices, when on cover cap to housing, the protrusion means are just in position, This embodiment is referred to shown in Fig. 9 a to Figure 10 c.

Such as in this Fig. 3, protrusion means 31 can specifically be arranged on the soft of the upstream of the pump impeller 11 of fluid drive apparatus On the installation path of pipeline；As described in Fig. 5 a are Fig. 3 at protrusion means soft pipeline partial enlarged drawing, referring to Fig. 5 a, this reality Apply protrusion means 31 described in example to be fixedly installed on housing, just already belong to position, when the soft pipeline 152 is in Under installment state, the first side of 301 pairs of the convex top soft pipeline 152 of the protrusion means implements to compress, and makes the soft pipe First side on road 152 is bent corresponding to being produced at the convex top 301.First side refers to soft pipeline 152 towards described convex Play the side of mechanism 31, should the description of " first side " be for mutually being distinguished with " the second side " hereinafter, rather than represent important journey Degree and order and each other existing premise etc..In one preferred embodiment of the invention, the of the soft pipeline 152 Side is an obtuse angle in bending angle caused by 301 places of convex top, can also be other angles in other embodiments certainly Degree.

Raised respective sensor 32, it is placed in the convex top of the protrusion means when protrusion means 31 are in position 301 correspondence position, for detecting the deformed state of the soft pipeline 152 at the convex top 301, testing result is transmitted To identified upstream module 33.The raised respective sensor 32 can be photoelectric sensor or sonac, or it is other can be with Detect the sensor of soft pipeline change in shape.Fig. 4 is a kind of left view of upstream occlusion detection means described in Fig. 3.Referring to Fig. 3 And Fig. 4, the raised respective sensor 32 is placed in lateral location corresponding to the convex top 301 of the protrusion means, convex described in Fig. 3 The portions in phantom that respective sensor 32 is blocked by soft pipeline 152 and protrusion means 31 is played to represent.The raised respective sensor 32 detection zone covers bending part of the soft pipeline 152 at the convex top 301 of protrusion means, by photoelectricity, ultrasound, Or other induction modes detect the deformed states of the soft pipeline at the convex top 301, such as the soft pipeline narrows or become The state such as thick.

Identified upstream module 33 can realize that information communicates with the raised respective sensor 32, for according to the projection The testing result that the transmission of respective sensor 32 comes is judged that the soft pipeline at the convex top 301 narrows to specified numerical value, Then judge upstream occlusion occurs.The identified upstream module 33 can be specifically a kind of logic judgment processing module, can be arranged on The inside of the fluid control devices, as long as its logic judgment processing function can be realized, its specific implementation present invention is not Limit, such as can be realized with software or realized with the mode of hardware realization or software and hardware combining.

It is a kind of form of the soft pipeline 152 in no generation upstream occlusion as shown in Figure 5 a, in this form Under, under the driving of the pump impeller 11, the interior fluid of the soft pipeline 152 is in normal flowing.Fig. 5 b are in generation A kind of form schematic diagram of soft pipeline when trip blocks.Referring to Fig. 5 b, in the event of upstream occlusion, such as in the valve machine Occur to block in structure 13 or blocking etc. occurs in the upstream of valve system 13, now because pump impeller 11 continues to drive soft pipeline Internal flow downstream flowing, then because the reduction of the fluid in the soft pipeline of the upstream of pump impeller 11, upstream do not have new stream again The supplement of body, then the soft pipeline of the upstream of pump impeller 11 can be caused more quickly to shrink and narrowed；If without spy of the present invention The construction of different protrusion means, then soft pipeline is when generation upstream occlusion causes deformation, it may occur that random movement, can not utilize Sensor is detected.Due to the construction of the protrusion means of the present invention, 301 the first sides for compressing soft pipeline are pushed up by convex, no But make it that soft pipeline 152 is relatively stable when upstream occlusion occurs, the position of the first side of soft pipeline 152 is basically unchanged, And opposite side is that the second side can relatively quickly be drawn close to the first side so that soft pipeline 152 is curved at the convex top 301 The raw obvious morphologic change of folding part distribution, i.e., significantly narrow；This obvious morphologic change is highly convenient for detecting, even if sharp This obvious morphologic change is may also detect that with the sensor of lower cost.Therefore, it is described convex when upstream occlusion occurs Play the can of respective sensor 32 and accurately and timely detect that the obvious form of soft pipeline generation at the convex top 301 changes Become, and send the synchronizing information of this morphologic change to the identified upstream module 33, identified upstream module 33 so as to Judge upstream occlusion occurs in time.

Fig. 6 is a kind of top plan view of protrusion means described in Fig. 5 a.In an advantageous embodiment, as shown in fig. 6, institute The convex top 301 of protrusion means 31 is stated, can be a kind of arcs of recesses structure, so as to be brought into close contact with soft pipeline 152.It is this On the one hand arcs of recesses structure can play stable effect to soft pipeline 152, i.e., when soft pipeline 152 occurs for upstream occlusion Soft pipeline is avoided to produce large-scale random movement during obvious deformation, on the other hand can play makes when upstream occlusion occurs The soft side of pipeline first (side contacted with the convex top 301) is relatively fixed, and the unexpected of relative displacement occurs for the second side Effect, this effect more can facilitate sensor to be accurately detected, improve the accuracy of detection.Certain Fig. 6 institutes The cross-section structure for stating the convex top 301 of protrusion means 31 is that more preferably embodiment, its cross-section structure can also use one kind Other shapes of structure.

More specifically, it is specified to judge that the convex soft pipeline pushed up at 301 narrows to for the identified upstream module 33 Numerical value, then judge upstream occlusion occurs.Specified numerical value herein, can rule of thumb preset a numerical value；Can also It is a ratio value, i.e., from the narrowed width of the soft pipeline shown in Fig. 5 a at convex top 301 to designated ratio (such as 1/4 or 1/5 Deng)；It can also be numerical value when determining a blocking, and store, judge in operation afterwards if the numerical value is reached Generation upstream occlusion.

In order to which soft pipeline maintains a relatively stable state when further making generation upstream occlusion, sensor detection is improved Accuracy.In an advantageous embodiment, the upstream occlusion detection means can further include at least one support member, It is oppositely arranged with the convex top of the protrusion means；The position feature of the support member is：It is in and has installed in the soft pipeline Under state, the top of the support member implements to compress to the second side of the soft pipeline, makes the soft pipeline relative limit Between the support member and the convex top of the protrusion means；First side and the second side direction are relative.

At least one support member is arranged between the convex top of the protrusion means and pump impeller.The convex top and the branch Support member produces pressure in opposite direction to the soft pipeline so that the installment state of soft pipeline is relatively stable.Further Preferred embodiment in, the support member can be two, be separately positioned on the both sides up and down on the opposite of the protrusion means.

It is illustrated in figure 7 a kind of schematic diagram of the further upstream occlusion detection means containing support member.Referring to figure 7, in the relative side in the convex top 301 of the protrusion means 31, support member 71 and support member 72, support member 71 and support member are set 72 are separately positioned on the both sides up and down of 301 horizontal extension lines of the convex top；The top of support member 71 and support member 72 is to described soft Matter pipeline the second side (i.e. with it is described it is convex top 301 contact sides opposite side) implement compress, make the soft pipeline relative limit In the support member 71 and support member 72 and between the convex top 301 of the protrusion means.This structure, soft pipeline with The contact site A of support member 71, the contact site C with the contact site B of support member 72, with convex top 301, all in relatively-stationary shape State, when upstream occlusion, it is only that contact site C opposites side i.e. position E (is located at soft that the most obvious region of morphologic change, which occurs, Second side of pipeline), the raised respective sensor 32 detects to position E, when upstream occlusion occurs, position E Significantly displacement can occur (by taking direction shown in Fig. 7 as an example) from left to right, even lower-cost sensor can be also easy to This obvious displacement is detected, and then upstream occlusion can be identified.Therefore this design feature not only increases detection upstream Promptness, sensitivity and the accuracy of blocking, and cost is relatively low.

It is similarly similar with the horizontal section of the protrusion means, the support member 71 and support member 72 and soft pipeline contact The horizontal section in portion or a kind of arcs of recesses structure, so as to be brought into close contact with soft pipeline 152.

In the above-described embodiments, the protrusion means, the support member and the fluid drive apparatus are all disposed within described The housing side of fluid control devices.

The raised respective sensor 32 can use the sensor of monomer structure, and in this case, the projection is corresponding to be passed Sensor is placed on the housing of the fluid control devices, or is placed on lid but is the need to ensure that the lid under the state that covers The detection range of the raised respective sensor 32 can cover the soft pipeline at the convex top 301.

Certainly, can if the raised respective sensor uses the sensor of emission part and acceptance division for Split type structure So that the Part I of the raised respective sensor is arranged on the housing of fluid control devices, and Part II is then arranged on institute Housing to be stated to correspond on lid, when on cover cap to the housing, the Part II is just relative with Part I, so as to To realize the detection function of raised respective sensor.As Fig. 8 be Fig. 6 shown in visual angle another embodiment schematic diagram, referring to Fig. 8, the raised respective sensor are split type, i.e., Part I 321 and Part II 322, wherein Part I 321 are set On housing 800, Part II 322 is arranged on lid 810；When in use, lid 810, Part II 322 and are closed A part 321 is just relative, and in position, detection range therebetween covers the convex soft pipeline pushed up at 301 152。

In a further embodiment, the protrusion means can not also be set simultaneously with fluid drive apparatus (especially pump impeller) Put in the housing side of fluid control devices, and be provided on the lid of fluid control devices.

Fig. 9 a and Fig. 9 b are a kind of showing for upstream occlusion detection means that protrusion means are arranged on the lid of fluid device It is intended to, Fig. 9 a are front view, and Fig. 9 b are left view.

The lid 810 includes two states：One kind is open mode；Another kind is to cover state, i.e. the lid of lid 810 arrives State on the housing 800.The lid 810 as described in Fig. 9 a is open mode, and the protrusion means 31 are arranged on the lid 810 inner side.Lid 810 shown in Fig. 9 b is in the relatively parallel partition state with housing 800, can from the state The relative status of support member 91 and 92 on to the protrusion means 31 and the housing.
