Abstract
The utility model discloses a pressure-sensitive infusion alarm device, comprising a pressure-sensitive sensor, a controller and an alarm device, wherein the pressure-sensitive sensor is in a ring shape, a hook is arranged at the lower end of the pressure-sensitive sensor, the pressure-sensitive sensor is connected with a singlechip of the controller, and the singlechip is respectively connected with a power supply and the alarm device. On the basis of the pressure-sensitive sensor, in the pressure-sensitive infusion alarm device, the alarm is realized by triggering the singlechip in a weight-reduction way, and when liquid is almost dripped off, an alarm signal can be sent out immediately to notice medical care personnel to remove an infusion pipe, thereby reducing the anxieties of patients and caretakers.
Description
One, technical field: this utility model relates to a kind of alarm device, particularly relates to a kind of pressure-sensitive infusion alarm.
Two, background technology: in process was cured the disease in transfusion, patient or families of patients need be observed fluid flow, and medical personnel also will often make an inspection tour, and whether inspection liquid uses up and in time follow up.This has increased the weight of patient's human cost and medical personnel's workload to a certain extent, if careless mistake will be brought very big trouble and misery to patient.
Three, utility model content:
This utility model technical problem to be solved is: overcome the deficiency of prior art, provide a kind of simple in structure, easy to use, keep watch on effective and reduce the pressure-sensitive infusion alarm that medical personnel make an inspection tour.
The technical scheme of this utility model: a kind of pressure-sensitive infusion alarm; Contain voltage sensitive sensor, controller and alarm; Said voltage sensitive sensor is an annular; Its lower end is provided with hook, and said voltage sensitive sensor is connected with the single-chip microcomputer of said controller, and said single-chip microcomputer is connected with said alarm with power supply respectively.
Said alarm is buzzer or speech player.
The beneficial effect of this utility model:
1. this utility model is the basis with the voltage sensitive sensor weighing principle, and single-chip microcomputer is judged according to the input signal of voltage sensitive sensor, when liquid will drip off, can report to the police immediately, and prompting medical care people in time pulls out tube for transfusion, has reduced patient and those who accompany the bed's anxiety.
2. this utility model does not contact medicinal liquid, can not produce medicinal liquid and pollute.
3. this utility model structure is small and exquisite simple, cheap, can be repeatedly used, and use cost is low.
4. this utility model is practical, and is easy to use, and the scope of application is wide, and market is huge, has significant application value.In addition, it can also constitute a remote alarming system with hospital's existing equipment, accomplishes the remote alarms function jointly.
Four, description of drawings:
Fig. 1 is the user mode figure of pressure-sensitive infusion alarm;
Fig. 2 is the circuit theory diagrams of pressure-sensitive infusion alarm.
Five, the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-infusion support, 2-controller, 3-voltage sensitive sensor, 4-hook, 5-infusion bottle.
Pressure-sensitive infusion alarm contains voltage sensitive sensor 3, controller 2 and alarm; Wherein: voltage sensitive sensor 3 is an annular; There is a circular hole centre, can pack on the drip stand, and its lower end is provided with hook 4; Voltage sensitive sensor 3 is connected with the single-chip microcomputer of controller 2, and single-chip microcomputer is connected with alarm with power supply respectively.Alarm adopts buzzer, also can record sound in advance, is cured in the speech chip, controls broadcast with controller.
During use, voltage sensitive sensor 3 is sleeved on infusion support 1 upper end, and infusion bottle 5 hangs on the hook 4, when liquid is full; Infusion bottle 5 gravity are bigger, make voltage sensitive sensor 3 not have signal to produce, and when liquid was totally lost gradually, the gravity of infusion bottle 5 diminished; The pressure that produces diminishes, and makes voltage sensitive sensor 3 have signal to produce, through the amplification of circuit; This signal can trigger single-chip microcomputer and produce interruption, calls interrupt service subroutine, produces alarm signal; After the nurse does handled, press another switch, warning stops.
The circuit working principle: when the pressure that has above the varistor greater than 0.01N, the resistance of YMDZ is bigger, and the P32 input voltage is 5V; When varistor bore pressure less than 0.01N, the resistance of YMDZ was less, and the defeated people's voltage of P32 is 0V.When the input voltage of P32 jumps to 0V by 5V, produce and interrupt, after handling through single-chip microcomputer, produce alarm signal.(10g＝0.001Kg；0.001Kg*10＝0.01N)
Specify: single-chip microcomputer can be adjusted the alarm pressure value of varistor.
Operation instruction:
1. infusion bottle 5 is suspended on the hook 4.
2. press start key, alarm sends " Bi-Bi " sound, the alarm start.
3. press start key again, alarm sends " Bi " sound, and green light is bright simultaneously, gets into duty.
4. after transfusion finishes, send " Bi-Bi " prompt tone continuously, chimes of doom is sent in the green light flicker simultaneously.
5. press resetkey, warning stops.
This device can be done together with hospital existing " phone system ", can initiatively send alerting signal to nurse station, when not transforming legacy system, has increased a safeguard that patient is responsible for.
Claims (2)
1. pressure-sensitive infusion alarm; Contain voltage sensitive sensor, controller and alarm, it is characterized in that: said voltage sensitive sensor is annular, and its lower end is provided with hook; Said voltage sensitive sensor is connected with the single-chip microcomputer of said controller, and said single-chip microcomputer is connected with said alarm with power supply respectively.
2. pressure-sensitive infusion alarm according to claim 1 is characterized in that: said alarm is buzzer or speech player.
