Here silica gel hose 103 is plastic products, and it is soft, flexible, pipe diameter will not change with internal pressure and Change, and soft durometer can change with overpressure, overpressure becomes strong, and hardness becomes strong；Overpressure diminishes, and hardness dies down.Should Silica gel hose, is not limited to transparent with opaque, and which kind of color is also not limited to is.

So form woven hose 100 when in use, the flowing of liquid in pipe be by peristaltic pump 105 (as shown in Figure 2) come Control.If obstruction (upper obstruction or lower obstruction block up and down) occurs in pipe will change pressure in flexible pipe simultaneously, then can It is directly perceived to reflect onto the soft or hard degree of silica gel hose.

Therefore, the utility model detects the diameter of woven hose or soft durometer change to detect woven hose by machine vision The change of interior pressure, it then can determine whether block in woven hose.

Accordingly, this programme by silica gel hose in machine vision technique indirect identification woven hose because woven hose overpressure become Caused by change soft durometer change, thus come realize detection transfusion overpressure change, then can determine whether sent out in woven hose Raw obstruction.

Specifically, this programme is by quoting an auxiliary detection device, silica gel hose in auxiliary detection device sensing woven hose Soft durometer change, and with silica gel hose soft durometer change can produce corresponding deformation.

Therefore, produced by this programme identifies that auxiliary detection device changes with silica gel hose soft durometer by machine vision technique Deformation quantity, thus come detect transfusion overpressure change, then can determine whether block in woven hose.

In order to accurately identify the deformation of auxiliary detection device, this programme is by setting corresponding identification region, the knowledge Other region is corresponding with image or video acquisition device taking lens, and is engaged with auxiliary detection device, its mirror that can be taken The size in the region of head shooting changes with the deformation of auxiliary detection device.

Thus, this programme further identifies the change of the identification region size based on machine vision technique, thus examines The change of transfusion overpressure is surveyed, then can determine whether block in woven hose.

For such scheme, the implementation process of detailed description below once this programme.

Referring to Fig. 2, it show the total of the woven hose overpressure detection means based on machine vision of this programme offer Body structure chart.

As seen from the figure, this detection means 200 mainly includes pump bin 210, collection and identification device 220, elastic construction 231, elastomer 232, these parts of darkroom 240.

Wherein, bin 210 forms the space structure for detection means, for disposing corresponding silica gel hose 102, wriggling Pump 105, motor 106, elastic construction 231, elastomer 232, darkroom 240, collection and identification device 220 etc..

Corresponding door lid 211 is provided with the bin 210, for forming the detection space of a closing, isolation is outside Interference, prevents foreign matter from entering；Prevent extraneous light from entering in bin simultaneously, influence camera and take pictures shooting, to ensure the present apparatus Reliability.

Here peristaltic pump 105, motor 106, the transparent pipe 101 of silica gel hose 102 and first and the second transparent pipe 103 For the plan of establishment of existing automatic infusion pipe, it is not repeated here herein.

Darkroom 240, it is arranged in bin 210, forms the shooting space of a closing, for collection and identification device 220 shooting elastomers 232.

As shown in Figure 2 and Figure 5, the both ends of the darkroom 240 appearance silica gel hose 102 pass through side by side, and are connected by joint 104 In the first transparent conduit 101, the second transparent conduit 103；And setting one can not among the both ends arranged side by side of silica gel hose 102 The baffle plate 243 of deformation；The connecting portion 241 set simultaneously in the bottom in the darkroom 240, for connecting collection and identification device 220； The top in the darkroom 240 is provided with corresponding cover plate 242, and the cover plate 242 corresponds to the top of darkroom 240, is arranged on door lid 211 On.

In specific implementation, the cover plate 242 in this programme can be further used as corresponding background board, for detecting door lid Whether 211 close.

Preferably, it is provided with the background board 242 for detecting pattern and/or the color whether door closes.As used White background plate, white, and whole white or other colors are not limited to, or with special icon.So can be by gathering And identification device detects whether door closes by shooting and identifying on background board pattern and/or color.Such as when camera pair Bin is taken pictures, and in the picture of acquisition, judges whether FX has the icon in picture, to detect whether door closes.

In addition, the shooting, collecting of the collection and identification device 220 for the ease of bottom, the bottom in darkroom 240 be it is transparent, Using fully transparent material form, so in this darkroom 240, silica gel hose 102 be fixed on be below fully transparent material it On, while touch can not deformation dividing plate 243, relative with dividing plate 243 be can be while soft in silica gel with the elastic construction of deformation The top of pipe 102 is white background plate 242.

Such fully transparent material, can be glass, it may also be said to be acrylic board, but do not limit to both.This is saturating The effect of bright material is that machine vision is taken pictures with camera through the transparent material to the elastomer of elastic construction, and is completely cut off External contamination.

Referring to Fig. 2 and Fig. 3, the elastic construction 231 in this programme coordinates with elastomer 232 forms auxiliary detection device 230, Soft durometer for sensing silica gel hose 102 in woven hose changes, and can change with silica gel hose soft durometer and produce accordingly Deformation.

The auxiliary detection device 230 is arranged symmetrically on the both sides in darkroom 240, for detecting silica gel hose 102 positioned at compacted The soft durometer change in the dynamic upper and lower part region of pump 150.

Specifically, elastic construction 231 and elastomer 232 are symmetrically placed positioned at the both sides of darkroom 240 respectively, elastic construction 231 Pass through resilient support elastomer 232；And elastomer 232 can be tied by the resilient force inside elastic construction 231 in elasticity Telescopic moving in structure, and with the tube wall of certain elastic force extruding silica gel hose 102, the elastic force direction is perpendicular to silica gel hose wall.

Due to there is darkroom Internal baffle 243 among silica gel hose 102, baffle plate 243 is non-movable.When silica gel hose 102 is soft or hard When degree change, it will the power different to elastomer 232, (left and right is moved radially along silica gel hose 102 to elastomer 232 is made It is flexible).So that elastomer 232 can be slidably according to the change of silica gel hose soft durometer, sliding block.

Referring to Fig. 4, in specific implementation, elastic construction 231 is made up of corresponding elastic portion, 231a and housing 231b, its Middle elastomeric element is placed in housing, and housing is placed in relative to silica gel hose 102 in the side wall in darkroom 240.Elastomeric element With corresponding elastic force, elastomer 232 is driven with support, the tube wall of silica gel hose 102 can be extruded with certain elastic force.

Here elastomeric element can according to the actual requirements depending on, as long as enabling to elastomer to extrude silicon with certain elastic force The tube wall of glue flexible pipe 102.As an example, the elastomeric element can be helical spring or spring leaf etc..

Here 232 preferred movable sliding block of elastomer, can be under elastomeric element and silica gel hose interaction Move back and forth between elastomeric element and silica gel hose.Specifically, the elastomer 232 its by elastic construction 231 elastomeric element Driving can be close to silica gel hose wall with certain elastic force, and according to the change of silica gel hose soft durometer, sliding block can be slidably. Its direction moved is determined that silica gel hose is harder by the soft durometer of silica gel hose 102, and elastomer moves toward elastomeric element direction, together When elastomeric element be extruded；Silica gel hose is softer, and elastomer moves toward silica gel hose direction, elastomeric element elongation, silica gel hose It is extruded.

The auxiliary detection device 230 set accordingly, as long as identification movable sliding block 232 (elastomer) is soft relative to silica gel The displacement of pipe 102 and direction, that is, it is capable of the change of effective detection silica gel hose soft durometer, thus can detect woven hose internal pressure The change of power, it then can determine whether block in woven hose.

On this basis, in order to which accurate reliable identification movable sliding block 232 (elastomer) is relative to silica gel hose 102 Displacement and direction, this programme sliding block 232 towards collection and the face of identification device 220 on (i.e. the lower section of sliding block 232, gather And the region of the shooting of identification device 220) corresponding identification region 250 is set.The identification region 250 and collection and identification device phase It is corresponding, and as sliding block 232 is relative to the movement of silica gel hose 102, the area that its collected and identification device is shot is adjusted in real time The size in domain.So, collection and identification device 220 are by gathering and identifying the change of the size of identification region 250, you can effectively know Other movable sliding block 232 (elastomer) is relative to the displacement of silica gel hose 102 and direction, and this makes it possible to effective detection silicon The change of glue flexible pipe soft durometer, the change of transfusion overpressure is thus can detect, then can determine whether hindered in woven hose Plug.

Specifically, the identification region 250 by sliding block 232 application fix color and form, and between silica gel hose Reserved a certain distance.Which kind of color is the color be not limited to, but to be subject to the color of background board, and the color of silica gel hose Distinguish.

Such application is not limited to whole applications and part application, and what the shape of the color region of application is also not limited to Kind shape.

Thus the identification region 250 (i.e. color region) formed, when being disposed with auxiliary detection device 230, at one part The region that camera is shot in collection and identification device 220, other part are the region that non-camera can be shot.

Thus, work as movable sliding block, because the soft durometer of silica gel hose changes, and move.The color region is in shooting The region of head shooting is also different.For example when woven hose overpressure becomes small, the hardness of silica gel hose diminishes, movable sliding block Due to the elastic force by spring, the extruding degree to silica gel hose is bigger.Color region under sliding block, as sliding block is overall to silica gel Flexible pipe slides, and the region into camera shooting is more.Camera is taken pictures in real time, then the color region in the image collected Become big, then it is assumed that the hardness of silica gel hose diminishes, and illustrates that woven hose overpressure diminishes.On the contrary, when woven hose overpressure becomes When big, the hardness of silica gel hose becomes big, supports sliding block to slide in and out, the color region under sliding block is in the region that camera is taken pictures Diminish, then the color region in the image collected diminishes, and judges that silica gel hose is hardened, and illustrates that woven hose overpressure becomes Greatly, so as to having reached testing goal.

Referring to Fig. 5 and Fig. 6, collection and identification device 220 in this programme are the processing center of whole detection means, and it is logical Cross and coordinate with auxiliary detection device 230 and identification region 250, one group of taking lens can be passed through, you can recognition detection woven hose Positioned at peristaltic pump top and/or the overpressure of lower area, obstruction and/or lower obstruction on woven hose then can detect.

Collection and the main camera part of identification device 220 and corresponding CPU part, wherein camera part are used for image Collection, the bottom in darkroom 240 is placed in by connecting portion 241, i.e., under silica gel hose 102；The camera is in CPU portions Under the control divided, LED illumination lamp of arranging in pairs or groups, elastomer is taken pictures in real time, and view data is passed to CPU part.CPU part is used In the processing and identification of completing image.

Here camera includes black and white camera or colour imagery shot；And camera by imaging sensor (CCD or CMOS) formed with camera lens；Camera lens is from the big depth of field, microspur.

Specifically, there is LED illumination lamp 221 inside coupling part 241, at the same among coupling part 241 and darkroom 240 across Hyaline layer (as described above).The hyaline layer is to obstruct external contamination, and complete printing opacity, and picture is shot beneficial to camera.

4 LED illumination lamps 221 are used in this programme, are respectively arranged at four angles of coupling part 241, and positioned at shooting Head side, and camera stretches out among coupling part 241.

In addition, being not limited to this for the installation position of LED illumination lamp 221, shooting head mirror is also can be placed in as needed Under head, on, under transparent material, or in background board, as long as (exterior light can must be shielded when camera is taken pictures Line), illuminating lamp is needed in dark bin, the shooting elastomer for being fully apparent from camera, you can.

Thus in the collection formed and the scheme of identification device 220, image that CPU is obtained is still image, namely camera lens is burnt Away from fixation, the image of shooting will not zoom, image content is constant.Because silica gel hose, baffle plate, background board are relative with camera solid It is fixed, so silica gel hose, baffle plate and background board appear in the fixed position of image, will not change.Under such circumstances, CPU points Image is analysed, particular coloured regions size below an analysing elastic structure, can be achieved with detecting the change of silica gel hose soft durometer, and then Realize the detection of overpressure.Simplify the complexity of software processing.

Thus form, detection means at work, clapped in real time by the speed of camera at least 1 frame per second by detection means The image related to identification region 250 is taken the photograph, then each frame picture of shooting is analyzed, identification silica gel hose soft durometer is It is no to change, thus come detect transfusion overpressure change.

Referring to Fig. 7, the picture of camera shooting includes：Two sections of silica gel hoses 102, baffle plate 243, the one of elastomer 232 Part, the region 250 (i.e. identification region 250) of the lower section special color of elastomer 232, white background plate 242.

In identification, the length scale in the main region 250 for judging special color it may determine that silica gel hose 102 it is soft Hard degree.Silica gel hose hardness is higher, compresses elastomer 232 and moves outward, the length in special color region 250 is smaller；Conversely, Silica gel hose is softer, and elastomer 232 moves inward, and the length of special color region 250 is bigger.

By analyzing fixed color region size, one is a simplified the complexity of graphical analysis；Second, eliminate, such as silicon The Color influences of glue flexible pipe.If the solid colour or close below silica gel hose color and elastic construction, will make at image Misjudgment is managed, triggers false alarm.Or silica gel hose is color and the elastic construction lower section of transparent material, internal solution or liquid Solid colour or close, can also make image error in judgement, trigger false alarm.So analyze designated color in image fixed position Area size, it is accurate both to have analyzed, and discharge interference, reduces software complexity again.

Realization principle based on more than, this detection means coordinates with infusion tube carries out automatic intravenous injection and automatic enteral During nursing, obstruction and lower obstruction in monitoring detection in real time.

The place that this detection means is blocked on silica gel hose 102 easily occurs close to the first transparent conduit 101, is provided with One group of elastic construction 231 and elastomer 232；The ground blocked in the case where silica gel hose 102 easily occurs close to the second transparent conduit 103 Side, is also provided with one group of elastic construction 231 and elastomer 232.

Thus, door lid 211 is closed, and peristaltic pump 105 extrudes silica gel hose in a manner of rotate counterclockwise is by wriggling, makes Internal liquid flows to silica gel hose 102 from the first transparent conduit 101, then flows to the second transparent conduit from silica gel hose 102 103, in patient body.

In the constant speed operation process of peristaltic pump 105, if the first transparent conduit 101 is held down, or infusion bag internal resistance Situations such as plug, occurs, that is, goes up obstruction, and now no liquid or seldom liquid flow into from the first transparent conduit 101, then Flow into silica gel hose, because influent tails off in silica gel hose, peristaltic pump ceaselessly drives again, causes liquid in silica gel hose Body is less, and now silica gel hose internal liquid tails off, and pressure just diminishes, and silica gel hose hardness softens.And elastomer 232 is by spring The effect of power, moved to silica gel hose.The special color region (i.e. identification difference 250) of the lower section of elastomer 232 appears in darkroom Interior length, camera captured in real-time to picture, CPU is delivered to, CPU judges FX in picture, and it is special to identify Color region is elongated, and special color region is elongated to a certain extent, i.e., there occurs upper obstruction, infusion pump or enteral nutrition pump to send Upper obstruction alarm.

In the constant speed operation process of peristaltic pump 105, if the second transparent conduit 103 hinders to this internal section Plug, that is, represent obstruction, now liquid normally flows into from the first transparent conduit 101, but liquid is from the second transparent conduit 103 outflows slow or not flowed.Liquid is set to assemble in silica gel hose close to the side of the second transparent conduit 103, pipe internal pressure Power becomes big, causes silica gel hose hardness increasing, compresses elastomer 232 and move outward, while special color region (identifies Distinguish the length 250) appeared in darkroom to shorten, camera captured in real-time to picture, be delivered to CPU, CPU judges solid in picture Determine region, identify that special color region shortens, special color region shortens to a certain extent, i.e., there occurs lower obstruction.Transfusion Pump or enteral nutrition pump send lower obstruction alarm.

Thus, can judge to block up and down respectively simultaneously by a camera.

On the advantages of general principle of the present utility model, principal character and the utility model has been shown and described.The industry Technical staff it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model can also There are various changes and modifications, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model will Protection domain is sought by appended claims and its equivalent thereof.
