Abstract
The utility model relates to an automatic alarm for infusion with an alarm circuit. The utility model is characterized in that the automatic alarm for infusion is composed of a probe and an alarm circuit. The probe is made of hard non-toxic plastic and forms a needle shape. Two non-contact stainless steel wires are sealed in the probe, and the top ends of the two steel wires extend out of the position of the needle tip. The alarm circuit is provided with NAND gate elements F1-F6, a red LED R, a green LED G, triodes T1 and T2, a musical film KD 9561 and a sounder B. The utility model has the advantages of easy implementation, simple structure and low cost. The utility model is suitable for any hospital and clinic with large scale, moderate scale and small scale.
Description
This utility model belongs to medical alarm device technical field, relates to a kind of transfusion autoalarm.
The patient who infuses in hospital has personal cognition, no matter whether patient's is in a bad way, all must wait for by the special messenger, for up to several hours, its purpose only be for transfusion fast finish time or please medical personnel in time pull out syringe needle, in order to avoid be input into gas, so not only waste of manpower and time, and increased a lot of entourages to hospital ward, influence management, health and other patients' in ward rest.In order to address this problem, in the prior art before this utility model, once took measures in a lot of wards, on each sick bed limit calling set is installed, patient can call out medical personnel by own Push switch when liquid is totally lost soon, this technology generally need be carried out project installation, wiring, and is cumbersome, and under, stupor seriously ill or the automatic situation such as sleeping, instead can cause delay patient.In addition, also announced the technology of several similar functions in the Chinese patent, as a patent application such as CN2210665Y, CN2117903U, its technical scheme is comparatively complicated, and there is no sophisticated product appearance.
State situation at above-mentioned existing skill, the purpose of this utility model is, provides a kind of technology reasonable.Simple structure, convenient and practical, need not guard personnel, do not need the do-it-yourself automatic infusion alarm calls of patient device yet.
Now this utility model technical solution is described below:
This utility model is made up of probe and warning circuit two parts; Probe is made by the hard non-toxic plastic, and profile is a needle-like, and the rubber stopper of infusion bottle is as the criterion its thickness can prick into smoothly, and envelope is buried two non-touching stainless steel silks in it, and expose at the needle point position of probe on the top of stainless steel silk; The two ends of warning circuit connect two stainless steel silks respectively, constitute the loop, have NAND gate element F
1-6, red, green light emitting diode R, G, audion T
1, T
2, musical film KD9561 Homeway.com Chinese percussion instrument B; One of light emitting diode terminates at non-gating element F
6With F
5Between, the other end is connected on F
2The F of four reversal connection parallel connections
1～4Between, audion T
1Base stage meet F
44 feet, colelctor electrode connects the input of musical film; Audion T
2Connect the outfan of musical film, colelctor electrode meets news Chinese percussion instrument B.
Below in conjunction with accompanying drawing operation principle of the present utility model is described further:
Fig. 1: this utility model warning circuit schematic diagram
Fig. 2: this utility model sonde configuration cutaway view
During use, will pop one's head in and prick in the transfusion bottle stopper, when the top of stainless steel silk in the probe is flooded by liquid, two stainless steel wires are connected by liquid, its terminal circuit taking alarm, and making (13) foot of not gate F6 in the circuit is low level, its (12) foot output high level, not gate F
5(10) foot output low level, and Red LED1 R conducting is again through not gate F
1, F

4After anti-phase, then make (2), (4), (6), (8) foot all become high level, audion T
1End, musical film is not worked, audion T
2Also do not work, news Chinese percussion instrument B is sounding not.When liquid level was exposed at the top of stainless steel silk, two stainless steel wires disconnected, and not gate F6 (13) is a high level by original low transition, and its (12) output low level causes not gate F
5(10) foot output high level, then green light emitting diode G conducting and send green light, Red LED1 R extinguishes, at this moment not gate F

4Outfan be low level, T
1Conducting, musical film get electric work, through T
2Amplify, the news Chinese percussion instrument is sent out the loud and clear chimes of doom of number.
The utility model is compared with prior art, and it is convenient, simple in structure, cheap to implement, and is suitable for In any large, medium and small type hospital and clinic, made things convenient for patient, saved and accompanied the people, be easy to the ward Management, increase work efficiency, be worth popularizing energetically popularization.
