Abstract
The utility model relates to a multifunction alarm, belonging to the technical field of medical appliance. The utility model is mainly composed of a casing and an alarm circuit which is hermetically arranged in the casing; two roots of electrode conducting wires 1 and 2 in the circuit are introduced at the outer end of the casing; a power switch, a luminescence display screen and a buzzing box are installed on the casing. The utility model can be used for infusion alarm and urine wet alarm, having the advantages of high safety, simple structure, high alarm accuracy.
Description
This utility model relates to a kind of multifunction alarm device.It belongs to medical instruments field.
Employed clinically infusion alarm mainly is the effect by spring at present, and the elasticity of spring and the length of the quality of spring-mass and service time are closely related, thereby has influenced the accuracy of reporting to the police; Existing urine-wet alarm device mainly is to detect by a temperature sensor whether urine is arranged, thereby reaches the purpose of warning, thereby also is subjected to the restriction of humidity sensor self function; These two kinds of equal performances of alarm are single, and reliability is relatively poor.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of can the warning as transfusion again can be as the multifunction alarm device of urine-wet alarm, and it is safe and reliable, and is simple and reasonable, warning accuracy height.
This utility model is achieved through the following technical solutions, and now is illustrated in conjunction with the accompanying drawings.
Accompanying drawing 1 is the circuit theory diagrams of alarm.
Accompanying drawing 2 is surface structure sketch maps of alarm.
As shown in Figure 2: will be welded with the circuit board package of warning circuit in housing 6, two electrode cables 1 of circuit and 2 draw in the housing outer end, and power switch 3, light emitting display 4 and buzzing case 5 are installed on the housing.
As shown in Figure 1: warning circuit is by power supply, resistance R1、R
2And R3, triode 9013, OC gate circuit, music triode, light emitting diode interconnect and form, and has two electrodes to be connected on respectively on lead 1 and 2 in the circuit; 1 1/474LS01,2 1/474LSO1, K1、K
2And K3Consist of.
This utility model is placed on lead 1 and 2 under the diaper during as urine-wet alarm device, when diaper is urinated when wet audion conducting, K by child
1And K
3Connection, K
2Disconnect; 1 is input as electronegative potential at this moment, is output as high potential, and 2 are input as high potential, are output as electronegative potential, and alarm signal is sent in the work of music triode, reaches the warning purpose; Otherwise when diaper did not have urine, audion ended, and the music audion is not worked, and did not have any signal and sent.
This product is connected lead 1 respectively with 2 during as infusion alarm with two syringe needles, two syringe needles are inserted in the liquid of fail triode conducting at this moment, K switch
2Connect, and K
1And K
3Disconnect, NAND gate 2 be input as electronegative potential, be output as high potential, the music audion is not worked; And when transfusion when finishing, two syringe needles expose, and audion ends, 2 inputs be high potential, output be electronegative potential, the work of music audion begins warning at this moment.
No matter this utility model clinically or in the daily life, all is the ideal using appliances of people.
