Description
Technical field
The present invention relates to automatic monitoring, specifically the automatic monitoring instrument of medical industry, when more specifically treating to patient infusion, pre-setting of automatic monitoring is carried out to infusion process and the automatic infusion monitoring device reliably dammed.
Background technology
Patient is being carried out in the process of infusion treatment, monitoring is being carried out to transfusion and is very important.The device monitored infusing in prior art adopts motor rotating mechanism to drive intermediate plate to dam (namely when the medicinal liquid in unusual circumstance or infusion bottle drips most substantially, block the liquid in tube for transfusion, liquid is no longer flowed and stopping infusion), there is the problems such as product structure complexity.
Summary of the invention
The object of this invention is to provide simple, easy to operate the pre-setting and the automatic infusion monitoring device reliably dammed of a kind of structure.
To achieve these goals, the present invention adopts following technical scheme.Of the present inventionly to pre-set and the automatic infusion monitoring device reliably dammed, comprise monitoring device and medicinal liquid control device, it is characterized in that: connect microprocessor after monitoring device, microprocessor also connects the signal circuit and medicinal liquid control device that are sent out by signal;
Described monitoring device is infrared detector;
Described medicinal liquid control device is made up of motor, driven wheel, tooth bar, guide rail and stator, driven wheel is placed on step motor shaft, tooth bar is arranged the tooth coincide with driven wheel, rack resting is on guide rail, the dead ahead of tooth bar is arranged opens stator jaggy, breach faces dististyle before tooth bar, and cut height is 1.5 ~ 3 times of dististyle thickness and four times of tube wall sums of infusing before tooth bar, and gap width is 1.5 ~ 3 times of end panel width before tooth bar.
The distinguished key technology that river closure mode of the present invention adopts is that its medicinal liquid control device is made up of motor, driven wheel, tooth bar, guide rail and stator, and the medicinal liquid control device of setting will make tube for transfusion bend.Front due to tooth bar is provided with out stator jaggy, and breach faces tooth bar, like this when motor rotates, the driven wheel be placed on step motor shaft will be driven to rotate, and then tooth bar is advanced along guide rail, before tooth bar, dististyle will protrude among the breach of front stator just, be in tooth bar front with stator in the middle of gap in tube for transfusion under the effect of tooth bar, also the breach of stator is entered in company with dististyle before tooth bar, tube for transfusion edge on breach produces 90 degree of bendings, 180 degree of bendings are produced in tooth bar front end, along producing 90 degree of bendings under breach, in these three bending places, tube for transfusion becomes flat and folding, liquid medicine flow in blocking tube, realize reliably damming.
And when needs recover liquid medicine flow, motor reverses under Systematical control, driven wheel also rotates backward, and then tooth bar is retreated along guide rail, before tooth bar, dististyle will exit among the breach of front stator, tube for transfusion is recovered to straight tube state due to natural resiliency by bending state, and medicinal liquid just can flow down smoothly.
Usually, after monitoring device, before microprocessor, amplifying circuit is set, so that transfer to follow-up microprocessor processes after amplifying the signal monitored.
In the present invention, infrared detector has two kinds of selections, and a kind of is combination for an independently infrared transmitting tube and one independently infrared receiving tube, and leaves the gap for placing tube for transfusion.The infrared tube of another kind to be infrared detector be integral type, to the gap had between pipe for placing tube for transfusion.The former is because freely can arrange the distance of transmitting tube and receiving tube, so be conducive to various consideration when designing, as infrared detector being positioned over the different position of different-diameter: as tube for transfusion, dropping funnel or infusion bottle oral area, the latter is but conducive to making product simplification, exquisiteness.
In infrared detector for placing the gap for placing tube for transfusion in the gap of tube for transfusion and medicinal liquid control device, be on same vertical line, infrared detector is positioned at the top of medicinal liquid control device.
The described breach middle part be arranged on a slice stator becomes four limit breach or the side be arranged on a slice stator to become three limit breach, or is combined into seam both sides breach by upper and lower two panels stator.Various mode is each has something to recommend him, the four limit breach at middle part belong to the most stable, that intensity is maximum frame mode, and the three limit breach being arranged on side are easy to processing, upper and lower two panels stator is combined into the both sides breach of seam, and the comparatively complicated but height being beneficial to adjustment seam of its structure to dam effect to obtain the best.
Usually, material selected from metal and the plastics of stator are made.
In order to ensure that tooth bar enters breach better, tooth bar front end plate shape is similar to notch geometry.
In order to reliably dam better, before tooth bar, dististyle should be good with smooth thin slice, and before tooth bar, dististyle thickness is that 0.5 ~ 2mm is better.The bending being 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 effect of damming.
Consider from the aspect durable in use of tooth bar and intensity in addition, the material making tooth bar is good with metal, intensity and the good plastics of hardness also most suitable.
The driven wheel be placed on step motor shaft both can be horizontal gear, also can be bevel gear.Accordingly, the tooth of tooth bar also should be the flat tooth or umbrella tooth that match with it.When adopting horizontal gear, motor is placed in the sidewall of shell, is in vertical with tooth bar, so that be engaged with the flat tooth of tooth bar.When adopting bevel gear, motor is placed on the base plate of shell, is in same plane with tooth bar, is convenient to be engaged with the umbrella tooth of tooth bar.
Of the present inventionly pre-setting and the automatic infusion monitoring device reliably dammed, is the terminal being placed in sick bed.Exchange is placed in nurse station.Terminal and exchange support the use performance function.Exchange is display alarm lamp and sounds the alarm, and reminds nurse or other staff.With automatic infusion monitoring device of the present invention with the use of exchange can be the system being arranged on now hospital.Current such system is generally all reported to the police by patient's manual operation button switch.The signal of terminal of the present invention is accessed current system, then forms the complete automatic system for monitoring transfusion of complete set.So just can make full use of the existing equipment of hospital, when not increasing too many spending, manual alarm being upgraded to automatic monitoring and reports to the police.
Terminal of the present invention can also other various exchanges on supporting market, and wired or wireless mode can be adopted to connect exchange.
In addition, hospital also can utilize terminal of the present invention, self-developing exchange.
Beneficial effect of the present invention is:
1, volume is little, lightweight, is convenient to hang use.
2, cost is low.
3, control reliably.
4, easy to operate, simply, only need to press the button switch.And do not need other any unnecessary actions.
5, microprocessor is convenient to pre-set, and setting working procedure, can adapt to various situation, can expanding function.As: monitoring device is placed in dropping funnel, and increase microprocessor module is set, just can carry out scene and arrange.After adjusting infusion flow rate, press and module record flow velocity is set, and the bound of flow velocity is set.As long as when flow velocity exceedes the limit (upper limit or lower limit) of this setting, just carry out reporting to the police and damming.Therefore, the present invention not only with or without medicinal liquid in monitoring transfusion pipe, can also monitor medicinal liquid flow velocity, more be convenient to note abnormalities.
