Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of single-chip microcomputer infusion alarm.
Background technology
Infusing continuously in hospital at present is a kind of common Therapeutic Method, needs in time to change transfusion bottle when every bottle of transfusion finishes, in case the generation of non-return blood phenomenon.The product of more existing monitoring infusion classes, but these products mostly accuracy do not reach the practical false alarm phenomenon that requires maybe can to occur in various degree, reasonable inadequately as some spring infusion alarm structures, the liquid residue deviation is very big in the warning time point drop bottle, and sensitivity and accuracy do not reach practical requirement; And some adopt the infusion alarm of photoelectric sense technology, and regular meeting thinks one section bubble or gas column by mistake to be transfusion finishes, and its sampled signal is subject to extraneous light restriction etc., and it is big to install and fix the complicated operation difficulty; And existing infusion alarm can not satisfy the needs of medical general different size model infusion products mostly, is difficult to promote; So low liquid level prompting is still finished by medical personnel's tour or patient's nurse in the transfusion of present most of hospital.
The utility model content
The purpose of this utility model provide a kind of warning promptly and accurately, rational in infrastructure, simple to operate and single-chip microcomputer infusion alarm that general applicability is strong, assist the requirements of one's work of infusing mutually to satisfy medical personnel and patient, overcome existing infusion alarm accuracy and do not reached and practical require or occur the false alarm phenomenon easily and install and fix complicated operation and defective that can not versatility.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of single-chip microcomputer infusion alarm, comprise housing, described case top is provided with supply hub, battery case, the case top center is provided with hook, the housing bottom center is provided with lower draw-bar, the housing middle part is provided with switch display lamp, main switch, display, relay indicating light, buzzer and signal output, and enclosure interior is provided with circuit board, bearing plate, pressure transducer, locating rack, Upper gasket, microswitch, lower gasket and spring; Described lower draw-bar top is straight-bar, described straight-bar can slide up and down, move up and down in order to toggle switch and drive bearing plate, described straight-bar passes housing bottom and stretches into enclosure interior, and straight-bar passes spring, lower gasket, Upper gasket, locating rack, pressure transducer and bearing plate from bottom to top; Described spring can make microswitch reset and straight-bar resets; Described pressure transducer is arranged at the locating rack top and is supported by locating rack, described bearing plate be arranged at described pressure transducer top and and pressure transducer between gapped, described lower gasket, Upper gasket, bearing plate are fixed on the described straight-bar; Circuit board is provided with signal amplifier, filter circuit, A/D converter and singlechip chip; In the described singlechip chip infusion program is housed, can carries out Weighing, interruption control, alarm signal and digital signal output.
During use, open main switch earlier, system's upper electrical switch display lamp is bright, on lower draw-bar, hang up infusion bottle again, lower draw-bar moves down to drive lower gasket compression spring and drive Upper gasket and moves down closed microswitch, when continuing to move down the drive bearing plate, lower draw-bar contacts with pressure transducer, bearing plate is exerted pressure to pressure transducer, pressure transducer produces voltage signal and amplifies through signal amplifier, filter circuit filtering, the input singlechip chip carries out infusion program processing and output, control after being converted to digital signal by A/D converter again, drive relay indicating light, display, buzzer.When taking off infusion bottle, spring reset promotes to move the disconnection microswitch on the lower gasket, and buzzer stops to report to the police, and display screen shows numerical value.
The beneficial effect of single-chip microcomputer infusion alarm described in the utility model is: measuring accuracy height, alarm are promptly and accurately; The interrupt operation of plucking bottle and extension bottle in the infusion process does not influence the warning quality; Applied widely, be applicable to the infusion products requirement of unlike material different size; Can independent alarm, also alarm signal in time can be sent to medical care center, be convenient to centralized Control; Volume is little, in light weight, rational in infrastructure, and is simple to operate, safe in utilization, easy to carry.
