Detailed description of the invention
Below by specific embodiment, the present invention is described in detail, should be understood that, these detailed description of the invention are only used for exemplifying the present invention, not forms any type of any restriction to real protection scope of the present invention.
Embodiment one
Embodiment of the present utility model provides a kind of infusion alarm, comprises shell, detecting signal unit, microprocessor, acousto-optic hint circuit.
Be the shell mechanism of the present embodiment infusion alarm as shown in Figures 1 to 6, this shell is C type encircling type housing 1, and this housing 1 inside forms a cavity 2.The top of this shell is the clamping part 11 for clamping Murphy's dropper top, the holding section 12 for being sticked in by Murphy's dropper is wherein extended below this clamping part, the shape of this holding section and Mo Feishi dropper and in the same size, and the cross-sectional area of clamping part is less than the cross-sectional area of holding section, the middle part of cavity 2 and top are provided with three grooves 13.In this utility model, also only can arrange some grooves at the middle part of cavity or the top of cavity, this groove is for settling detecting signal unit, and therefore, the size of groove and quantity are determined according to the quantity of sensor in detecting signal unit and size.As shown in Figure 7, be a kind of distressed structure of the shell of the present embodiment, wherein, a groove is set on the top of shell.
Detecting signal unit comprises C type groove photoelectric sensor and comparator.C type groove photoelectric sensor is for detecting the drippage situation of infusion liquid drop, and to comparator output detections signal, comparator is used for calculating output level according to detection signal, and outputs signal to microprocessor.
C type groove photoelectric sensor is located in the groove 13 of shell, as Fig. 8 (a) is depicted as the optical axis top view of C type groove photoelectric sensor, comprise three pairs of RF transmitters 21,22,23 and infrared receiver 24,25,26, these three pairs of RF transmitters 21,22,23 and infrared receiver 24,25,26 arrange the optical axis path defining " * " type according to certain angle.In this utility model, RF transmitter and the infrared receiver with certain angle are set, object detects the drippage situation of infusion liquid drop, therefore, except " * " type, three pairs of RF transmitters and infrared receiver also can be arranged according to other angles, form the optical axis path of other shapes, such as, shown in Fig. 8 (b) " || | " type optical axis path.Wherein, three pairs of RF transmitters and infrared receiver can be disposed on the same plane, and also can arrange on a different plane at a certain distance.
When infusion liquid drop drippage is through C type groove photoelectric sensor, at least one optical axis path can be blocked, namely a pair RF transmitter and infrared receiver can be had drips to be detected, also two can be had to drips being detected simultaneously, three can also be had to drips being detected simultaneously, and detection signal is exported to comparator.Comparator compares according to the detection signal received, when there is no drips, comparator exports high level, when there being drips, comparator output low level, the outfan quantity of comparator is corresponding to the logarithm of RF transmitter and infrared receiver, in the present embodiment, be provided with three outfans in the comparator of described signal deteching circuit, three that are connected respectively to microprocessor interrupt outward.
Microprocessor is octal single-chip microcomputer, is provided with five outer interruptions being set to trailing edge and triggering, and wherein has three to interrupt being connected respectively with the outfan of three in the comparator of signal deteching circuit outward.This single-chip microcomputer is used for the signal that Received signal strength detecting unit exports, according to signal interruption service routine.When there being drop to drip, the outfan of comparator has trailing edge and occurs, trigger single-chip microcomputer outage service routine, when not having drop to drip, single-chip microcomputer is outage service routine not.Three to interrupt outward arranging different interrupt priority levels other, when two or three interrupt occurring interrupt signal simultaneously, ensures that single-chip microcomputer only responds not high that of interrupt priority level and interrupts.Thus, any one by judging whether Single Chip Microcomputer (SCM) program run in three outer interrupt service routines, whether namely known have drop to drip.When there being drop to drip, single-chip microcomputer outage service routine, the signal lamp controlled in acousto-optic hint circuit sends green glow and glimmers; When the time continuing one longer does not detect that drop drips, any one in single-chip microcomputer off-duty three outer interrupt service routines, be judged as occurring abnormal conditions, the signal lamp of Single-chip Controlling acousto-optic hint circuit sends HONGGUANG and glimmers always, and buzzer sends the sound that ticks always and reports to the police.
Acousto-optic hint circuit comprises signal lamp and buzzer, and signal lamp is used for the signal lights sending different colours according to instruction, and buzzer is used for sending alarm sound according to instruction.Acousto-optic hint circuit comprises three kinds of functions: start prompting, and when being equipped with electric power starting infusion alarm, signal lamp sends green glow; Run instruction, when detecting that infusion liquid drop drips, signal designation sends green glow, dodges; Alarm: when transfusion completes or occur blocking, signal lamp sends HONGGUANG and glimmers always, and buzzer sends always, and " tick " alarm sound of " ticking ".
The infusion alarm of the present embodiment also comprises the low electricity warning circuit of power supply, for fed power supplies charge condition.The present embodiment adopts button cell to be that infusion alarm is powered as power supply.When cell output voltage is less than the reference voltage of setting, power supply low electricity warning circuit luminous alarm, reminds medical personnel to change battery in time.Specifically, power supply exports the positive input of input comparator after voltage stabilizing, and the reverse input end of comparator directly connects power positive end; When the voltage of supply voltage lower than stabilivolt, comparator exports high level, drives a lumination of light emitting diode to carry out alarm.
Embodiment two
The difference of the present embodiment and embodiment one is only signal deteching circuit, in the present embodiment, detecting signal unit is except C type groove photoelectric sensor and comparator, also comprise three value and gate, three inputs of this three value and gate are connected with three outfans of comparator, and the outfan of three value and gate is connected to the outer interruption of microprocessor.
The above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
