Abstract

The utility model discloses an automatic infusion detecting warning device which comprises a strain gauge pressure measuring module, a signal amplifying module, an AD (analog-digital) module, a microprocessor module, a display module, a warning module and a communication module. Working steps of the automatic infusion detecting warning device sequentially include that the pressure measuring module senses change of the pressures under 'needle heaving' conditions, the change of the pressures is converted into analog signals, then the analog signals are transmitted to the signal amplifying module, amplified signals are transmitted to the microprocessor module after being converted by the AD module, data are transmitted to a master processor module via the communication module after the amplified signals are processed by a microprocessor, conditions and positions are displayed by the display module, and warning effects are simultaneously realized by a warning device, so that medical staffs can reminded of timely handling the 'needle heaving' conditions. The automatic infusion detecting warning device has the advantages that remote monitoring effects can be realized, and accordingly humanized heart warming service can be embodied.

Description

A kind of transfusion automatic detection alarm device

Technical field

This utility model relates to intelligent transfusion alarm device, particularly a kind of transfusion of the electronic type based on foil gauge pressure measurement " drum pin " situation alarm device, and this device can detect hand transfusion situation, and points out nurse.

Background technology

Transfusion is the major way of curing the disease now, main by artificial nurse, but can not at every moment accompany and attend to by patient, in the time that patient is sleeping or neglectful movement causes " drum pin ", general discovery all too late, can not process in time, swelling meeting leaves psychological shade to patient.

Summary of the invention

While transfusion for reducing, because inadvertent causes unnecessary harm, ensure patient's physical and mental health, this utility model provides a kind of transfusion automatic detection alarm device, and the moment is detected hand transfusion situation, reaches the object of service next to the skin.

The technical solution of the utility model: a kind of foil gauge pressure measurement type intelligent transfusion alarm device, this intelligent alarm device comprises foil gauge pressure measurement module, signal amplification module, AD modular converter, microprocessor module, main processor modules, alarm module, display module and communication module.While there is " drum pin " situation, pressure measurement module senses that pressure changes, change into analogue signal and pass to signal amplification module later, the signal being exaggerated sends microprocessor module to after AD module converts, after microprocessor processes signal, these data are sent to main processor modules by communication module, display module demonstrates status location, and alarm device simultaneously warning reminding medical worker is processed in time, to realize remote monitoring, embody more humane warm genuinely convinced business.

Brief description of the drawings

Below in conjunction with accompanying drawing and example, this utility model is further illustrated.

Fig. 1 is system construction drawing of the present utility model.

Fig. 2 is that the concrete enforcement of this utility model foil gauge pressure measurement biography device is put on record.

In Fig. 1,1. foil gauge pressure measurement module, 2. signal amplification module, 3.AD modular converter, 4. microprocessor module, 5. communication module, 6. main processor modules, 7. display module, 8. alarm module.

In Fig. 2,9. foil gauge pressure tester HL-8,10.AD620 signal amplifying apparatus, 11.ADC0804AD modular converter, 12.STC89C52 single-chip microcomputer, 13.24L01 wireless module, 14.STC89C52 single-chip microcomputer, 15.LCD1602 shows, 16 buzzers.

Detailed description of the invention

As shown in Figure 2, this utility model can be divided into: foil gauge load cell (9), signal amplifying apparatus (10), AD conversion equipment (11), singlechip microprocessor (12), 24L01 wireless module (13), single-chip microcomputer primary processor (14), 1602 display screens (15), buzzer (16).

When this intelligence siren uses, foil gauge load cell (9) is placed in to hand, is fixed on the outside of syringe needle insertion hand position with medical adhesive tape, apart from 1～2 millimeter of place of syringe needle.While there is " drum pin " situation, pressure measurement module (1) senses that pressure changes, change into analogue signal and pass to signal amplification module (2) later, the signal being exaggerated sends microprocessor module (4) to after AD module (3) conversion, after microprocessor processes signal, these data are sent to main processor modules (6) by communication module (5), display module (7) demonstrates status location, and alarm device (8) simultaneously warning reminding medical worker is processed in time.

In the time there is " drum pin " situation, the quick swelling of hand skin, hand contacts the sake generation current signal that is squeezed with sensor (9).The signal of telecommunication is through AD602(10) amplify, be then voltage analog signal by AD conversion equipment (11), carried out data preliminary treatment by 51 singlechip microprocessor (12).

Processed data are sent to 51 single-chip microcomputer primary processors (14) through wireless transport module 24L01 (13), single-chip microcomputer (14) carries out comparing calculation to data and goes out relative difference, when difference is large, 51 single-chip microcomputers (14) are controlled buzzer (16) warning, and 1602 liquid crystal (15) show berth or the patient position of situation simultaneously.Process through above, realize the real-time monitoring to patient's transfusion, intimate service.
