Abstract
The utility model discloses a counter for an intravenous injection dropper, which belongs to medical equipment and comprises a dropper, a signal acquirer, an analog and digital conversion circuit, a signal processing module and an electronic display. Two poles D1 and D2 of the signal acquirer are directly mounted on two opposite lateral walls of a liquid drop outlet of the dropper, outputs signals of the signal acquirer are transmitted to the analog and digital conversion circuit, the analog and digital conversion circuit is in communication connection with the signal processing module by a data bus, output signals of the signal processing module are transmitted to the electronic display via an amplifying circuit, pin wires of digital tubes in the electronic display are correspondingly connected with the data bus to be further connected to the corresponding signal processing module, and another branch of the signal processing module is correspondingly connected with the analog and digital conversion circuit via a circuit. The counter adopts a single chip microcomputer as a signal processor, can count accurately, is high in precision and fast in response speed, can bring convenience for medical staff to continuously monitor, accurately master and adjust dropping speed of intravenous administration due to the fact that counting results can be used for automatically displaying the dropping speed on the digital display, and accordingly ensures safety of intravenous administration of a patient.
Description
Technical field
This utility model belongs to medical apparatus, particularly relates to a kind of intravenous injection dropper enumerator.
Background technology
At present, medical personnel adopt hand-timed method to estimate dripping number and dripping the foundation of speed as adjusting with this of per minute injection drop when injecting the drop treatment to the injury patient usually.Because the body constitution of dripping speed and injury patient of drop and the medicine of being injected are closely related, so adopt this method to estimate to drip fast, promptly science not is also dangerous.
Summary of the invention
This utility model is intended to overcome the deficiencies in the prior art, and a kind of intravenous injection dropper enumerator is provided.
Intravenous injection dropper enumerator of the present utility model is to be made of dropper, signal picker, analog to digital conversion circuit, signal processing module and electronic displays.The two poles of the earth D1 of signal picker and D2 footpath directly is installed on the relative two side of drop outlet of dropper, signal picker output signal to analog to digital conversion circuit, analog to digital conversion circuit is communicated by data/address bus with signal processing module and connects, the signal processing module output signal through amplifying circuit to electronic displays, the corresponding data/address bus that connects of the payment to a porter of each charactron is to corresponding signal processing module, the corresponding connection with analog to digital conversion circuit of another road via line of signal processing module in the electronic displays.
As further improvement of the utility model, described signal picker is made of corresponding light emitting diode D1 and optical transistor D2.
As further improvement of the utility model, described analog to digital conversion circuit is to replace with the DC0804 chip.
As further improvement of the utility model, described signal processing module is to replace with the 89C2051 single-chip microcomputer.
As further improvement of the utility model, described electronic displays is made of three common positive charactrons that three bit digital show.
Intravenous injection dropper enumerator volume of the present utility model is little, in light weight, be easy to carry, and this device adopts single-chip microcomputer as signal processor, can calculate accurately, precision is high, response speed is fast, and count results can demonstrate automatically by data display equipment and drip speed, therefore, be convenient to the speed of dripping that medical personnel continued to monitor, accurately grasped and adjusted fluid infusion, to guarantee the safety of injury patient fluid infusion.
Description of drawings
Fig. 1 is the structural representation of intravenous injection dropper enumerator of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
The specific embodiment
Intravenous injection dropper enumerator of the present utility model is to be made of dropper 1, signal picker 2, analog to digital conversion circuit 3, signal processing module 4 and electronic displays 5.Signal picker 2 is made of corresponding light emitting diode D1 and optical transistor D2, its the two poles of the earth D1 and D2 footpath directly is installed on the relative two side of drop outlet of dropper 1, signal picker 2 output signal to analog to digital conversion circuit 3, analog to digital conversion circuit 3 is communicated by data/address bus 6 with signal processing module 4 and connects, signal processing module 4 output signals through amplifying circuit 7 to electronic displays 5, the corresponding signal processing module 4 that connects data/address bus 6 to correspondence of the payment to a porter of each charactron in the electronic displays 5, another road via line 8 of signal processing module 4 and analog to digital conversion circuit 3 corresponding connections.Wherein, analog to digital conversion circuit 3 is to replace with the DC0804 chip; Signal processing module 4 is to replace with the 89C2051 single-chip microcomputer; Electronic displays 5 is made of three common positive charactrons that three bit digital show.
Its operation principle is: after each parts was connected electricity, light emitting diode D1 was luminous, penetrate dropper 1 after, impinge upon on the optical transistor D2.When having drop, dropper drips into, light intensity reduces, electric current by optical transistor D2 also reduces thereupon, exports analog-digital converter to by resistance, and analog-digital converter is given signal processor with sampled voltage, the signal processor timing sampling, and use certain algorithm and go to disturb, judge drop, note down the time between following two, be scaled the number that drips of per minute again, control LED charactron shows automatically.
