Description
Technical field
The present invention relates to automatic monitoring, the automatic monitoring instrument of medical industry specifically, carry out the device reliably dammed of automatic monitoring to infusion process while more specifically treating to patient infusion.
Background technology
In patient is carried out to the process of infusion treatment, transfusion is monitored and is very important.The device that transfusion is monitored in prior art adopts motor rotating mechanism to drive intermediate plate to dam that (the medicinal liquid in unusual circumstance or infusion bottle drips when most substantially, liquid in the blocking-up tube for transfusion, liquid is no longer flowed and stopping infusion), there are the problems such as product structure complexity.
Summary of the invention
The reliable cut-off equipment that the purpose of this invention is to provide a kind of simple in structure, easy to operate transfusion automatic monitoring.
To achieve these goals, the present invention adopts following technical scheme.
The reliable cut-off equipment of transfusion automatic monitoring of the present invention, comprise the mobile cut-off equipment of medicinal liquid in the blocking-up tube for transfusion, its cut-off equipment is comprised of motor, driven wheel, tooth bar, guide rail and stator, driven wheel is placed on step motor shaft, the tooth identical with driven wheel is set on tooth bar, rack resting is on guide rail, stator jaggy is opened in the dead ahead setting of tooth bar, breach faces the front dististyle of tooth bar, cut height is the front dististyle thickness of tooth bar and four times of transfusion tube wall sums 1.5 ~ 3 times, and gap width is 1.5 ~ 3 times of the front dististyle width of tooth bar.
The distinguished key technology that river closure mode of the present invention adopts is, its cut-off equipment is comprised of motor, driven wheel, tooth bar, guide rail and stator, and the cut-off equipment of setting will make the tube for transfusion bending.Because the place ahead of tooth bar is provided with out stator jaggy, and breach faces tooth bar, like this when motor rotates, will drive the driven wheel be placed on step motor shaft rotates, and then tooth bar is advanced along guide rail, before tooth bar, dististyle will protrude among the breach of the place ahead stator just, in tooth bar the place ahead with stator in the middle of gap in the effect of tube for transfusion at tooth bar under, also in company with dististyle before tooth bar, enter into the breach of stator, tube for transfusion bends along producing 90 degree on breach, produce 180 degree bendings at the tooth bar front end, under breach, along producing 90 degree, bend, in these three bending places, it is flat and folding that tube for transfusion becomes, medicinal liquid in blocking tube flows, realize reliably damming.
And when needs restorative liquid stream is moving, motor reversion under system is controlled, driven wheel also rotates backward, and then tooth bar is retreated along guide rail, before tooth bar, dististyle will exit among the breach of the place ahead stator, tube for transfusion is due to self elasticity and be recovered to the straight tube state by bending state, and medicinal liquid just can flow down smoothly.
Described breach is arranged on that middle part on a slice stator becomes four limit breach or the side that is arranged on a slice stator becomes three limit breach, or is combined into seam both sides breach by upper and lower two stators.Variety of way is each has something to recommend him, four frame modes that the limit breach belongs to the most stable, intensity is maximum at middle part, and the three limit breach that are arranged on a side are easy to processing, upper and lower two stators are combined into the both sides breach of seam, and its structure is comparatively complicated but be beneficial to the height of adjusting seam to obtain the best effect of damming.
Usually, the material of making stator is selected from metal and plastics.
In order to guarantee that better tooth bar enters breach, tooth bar front end plate shape is similar to notch geometry.
In order reliably to dam better, before tooth bar, dististyle should be take smooth thin slice as good, and before tooth bar, dististyle thickness is that 0.5 ~ 2mm is better.The bending that is more conducive to tube for transfusion like this, smooth thin slice can not damage tube for transfusion, too thinly likely can damage tube for transfusion, too thick impact bending and the effect of damming.
From aspect durable in use and the intensity of tooth bar, consider in addition, the material of making tooth bar be take metal as good, and the plastics that intensity and hardness are good are also most suitable.
The driven wheel be placed on step motor shaft can be both to be horizontal gear, can be also bevel gear.Accordingly, the tooth of tooth bar also should be flat tooth or the umbrella tooth matched with it.When adopting horizontal gear, motor is placed in the sidewall of shell, with tooth bar in vertical so that with the flat tooth interlock of tooth bar.When adopting bevel gear, motor is placed on the base plate of shell, with tooth bar, in same plane, is convenient to the umbrella tooth interlock with tooth bar.
Beneficial effect of the present invention is: bend pipe river closure mode uniqueness, and simple in structure, dam reliable.
The accompanying drawing explanation
Fig. 1 is the structural representation of cut-off equipment of the present invention;
Fig. 2 is a kind of form of stator in cut-off equipment of the present invention;
Fig. 3 is the another kind of form of stator in cut-off equipment of the present invention.
The specific embodiment
See Fig. 1.
Cut-off equipment of the present invention is comprised of motor 1, driven wheel 2, tooth bar 4, guide rail 6 and stator 7, driven wheel 2 is placed on step motor shaft 1, the tooth 5 identical with driven wheel 2 is set on tooth bar 4, tooth bar 2 is placed on guide rail 6, the dead ahead setting of tooth bar 4 has the stator 7 of breach 8, breach 8 faces the front dististyle 3 of tooth bar of tooth bar 4, and breach 8 is highly front dististyle 3 thickness of tooth bar and four times of transfusion tube wall sums 2 times, and breach 8 width are 2 times of front dististyle 3 width of tooth bar.
See Fig. 2.Stator 10 is a kind of forms of the stator 7 in Fig. 1, has breach 11, and breach 11 is arranged on three limit breach of a side, and stator 10 is made of plastics.
Before tooth bar, dististyle 3 is shaped as rectangle.
