Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
Embodiment one：
As shown in Fig. 1,4 and 5, a kind of syringe pump of the structure with whole infusion safety detection and near-space detection, including
Rack 10, motor 8, syringe 6, wherein motor 8 are connected by deceleration mechanism 9 with lead screw 7, and lead screw 7 is matched with clutch nut 3
Close, clutch nut 3 connect with push rod 4, push rod 4 by 5 and the connection of syringe 6 of cutting somebody's hair, set on clutch nut 3 there are one photoelectricity coupling
Clutch 2, sets that there are one the light barriers 1 coordinated with photoelectrical coupler 2 in rack 10.
Motor 8 rotates, and lead screw 7, the feed screw nut pair of lead screw 7 and clutch nut 3 are transmitted motion to by deceleration mechanism 9
Mechanical engagement, makes the linear motion for being changed into clutch nut 3 of lead screw 7, clutch nut 3 drive push rod 4 and cut somebody's hair 5 do it is straight
Line moves, the tail end for 5 promotion syringes 6 of cutting somebody's hair, to realize that automatic injection, photoelectrical coupler 2 are installed on clutch nut 3,
Clutch nut 3 is followed to move together.
Light barrier 1 is made of the catch being spaced apart, and gap is equipped between catch.It is defeated including near-space detection zone and whole process
Safety detection region is noted, near-space detection zone distinguishes the practical fortune of photoelectrical coupler 2 using the width of light barrier with gap difference
Dynamic position.For shown in Fig. 2, light barrier width and gap are using different sizes, and catch width is t0, and t1, t2 etc. are with such
It pushes away, is similarly t0, t1 for description simple hypothesis gap, t2 is waited and so on.Herein only as an example, other change case,
Such as equal difference, than expand or other using width and gap come the algorithm of demarcation of location.Whole process infusion safety detection area
Domain, the fixed width of each catch and gap, by taking Fig. 2 as an example, catch width is b, gap width c.Use it to detection injection
Whether pump has moved defined distance before the deadline.
When being transfused beginning, photoelectrical coupler 2 is likely located at whole infusion safety detection region or near-space detection zone,
It is simple to describe, it is assumed that photoelectrical coupler 2 is first located at whole infusion safety detection region, and photoelectrical coupler 2 is in and is hidden
Gear state, at this time photoelectrical coupler 2 be closed.After infusion starts, 2 setting in motion of photoelectrical coupler, between moving to
When at gap, photoelectrical coupler 2 is switched to conducting state, at this time the beginning timing as first record point.Infusion continues,
When photoelectrical coupler 2 moves to next catch, photoelectrical coupler 2 is blocked again to switch to closed state, this
Second record point of Shi Zuowei is calculated according to the infusion rates of setting, the width of the internal diameter of syringe and catch or gap
The real time H1 of the time T1 that syringe move distance b needs, the two record points passed through with photoelectrical coupler 2 are compared
Compared with, it can judge whether syringe is being injected according to the rate of setting, it is also or practical when practical switching time H1 is much smaller than T1
Switching time is much larger than T1, illustrates that system goes wrong：Clutch nut 3 is just in too fast either excessively slow movement or transmission
Chain damages, and system is not transfused.And so on, in the switching of next 2 conducting state of photoelectrical coupler each time, make
It is put for record to examine whether clutch nut 3 has moved the distance set in setting time.
Near-space detection zone：After infusion has carried out a period of time, when photoelectrical coupler 2 is surveyed in record point adjacent twice
When the turn-on time obtained is equal to the time T2 of 2 move distance t5 of theoretical calculation photoelectrical coupler, illustrate that photoelectrical coupler 2 has been transported
It moves to near-space detection zone, since this state only occurs in this algorithm once, so can accurately judge syringe push handle
Actually located position at this time.Also how many move distance is finished so as to which distance injection is calculated.Further when
When 2 state of photoelectrical coupler becomes conducting from closing again, the t5 that is blocked in catch with photoelectrical coupler 2 with the time H2 that measures
Compare apart from upper theory movement time T2, to judge that whether syringe pump is in the rate according to setting in near-space detection zone
It is transfused.And so on, continue to clearance distance t4, catch distance t4, clearance distance t3 etc. judges successively, due to each shape
State is unique states in the algorithm, therefore can know the physical location residing for syringe in each record point, until being transfused
Finish, into KVO states.
As shown in figure 3, when injection measurement is smaller, the position that syringe starts infusion may have been positioned at algorithm flow chart
Near-space detection zone, this algorithm is still effective, repeats no more.Photoelectrical coupler 2 passes through each of light barrier 1 successively from right to left
Light barrier and gap location utilize the variation of 2 conducting state of photoelectrical coupler, the time interval of detection conducting state variation each time
H accomplishes whole infusion safety detection and near-space in conjunction with the theoretical time T being calculated according to injection rate and syringe internal diameter
Detection.
Embodiment two：
The light barrier 1 only has whole infusion safety detection region, whole process uses equal wide and gap, only realizes
Detection infusion security function.
Embodiment three：
The light barrier 1 only has near-space detection zone, and whole catch width is all made of t0, t1, t2 until tn combination, or
Person uses t0, t1, t2 to drop to t2, the form of the Symmetric Composite of t1, t0 until tn, then from tn, i.e., all catch and gap are adopted
With different width and gap come to carry out whole real time position detection.Increase a pair of of photoelectrical coupler 2 and light barrier 1,
It carries out more complicated more accurate position and safety detection belongs to the protection domain of this patent.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
