Abstract

The utility model provides a transfusion alarm device for medical care. Adopting the lever principle, the utility model can achieve the monitoring and warning effect in the processes of the transfusion by the cooperation of a hanging mechanism, a contacting block, a spring and a micro switch; the hanging mechanism, the contacting block and the spring are installed on a hogged rod; the micro switch is communicated with the circuit of the acoustic-optic alarm device. The utility model has the advantages of simple structure, low manufacture cost and convenient operation.

Description

Transfusion alarm device

This utility model relates to a kind of medical apparatus and instruments, particularly be medical infusion alarm.

In infusion process, for labor intensity that alleviates medical personnel and the safety that guarantees the transfusion patient, people have developed bonded transfusion alarm device electronics or dynamo-electric, are that the medical automatically drip-stopping alarm infusion apparatus of CN2041957U and the intravenous drip automatic closing and alarm device of CN86204200U promptly belong to this type of as the notification number of reporting on the Chinese utility model patent communique.Above-mentioned two kinds of devices can reach the effect that not only alleviates medical personnel's labor intensity but also can guarantee patient's safety, but its mechanical part has the structure more complicated, the shortcoming that cost of manufacture is higher.

The purpose of this utility model provides a kind of infusion alarm simple in structure.By adopting lever principle,,, overcome the baroque shortcoming of its mechanical part in the prior art in conjunction with sound and light alarm equipment with simple frame for movement.

The technical solution of the utility model is formed by sticking up bar, support column, base and acousto-optic warning device, support column upper end with stick up the bar hinge joint, the lower end is contained on the base.Stick up suspension gear, contact block and spring are housed on the bar.And, the microswitch that matches with contact block also is housed.

Suspension gear is drop hanger or suspension ring, is contained in the below of sticking up bar one end, contact block be contained in stick up this end of bar above.The microswitch that matches is installed in a distance, contact block top.

Described spring is extension spring, its upper end with stick up that bar one end is connected, the lower end is contained on the base.

Above-mentioned package assembly is that support column is contained in the middle part of sticking up bar.As the installation site transposing with support column and spring, then spring is a stage clip.

This utility model has that structure is simpler, a low cost of manufacture, easy to use and reliable advantage compared with the prior art.

Accompanying drawing drawing explanation of the present utility model:

Fig. 1: mechanical part view of the present utility model

Fig. 2: the circuit diagram of this utility model sound and light alarm equipment.

Below in conjunction with embodiment (accompanying drawing) this utility model is further described:

As Fig. 1-shown in Figure 2, the upper end of support column 1 and the middle part hinge joint of sticking up bar 2, its lower end is contained on the base 3.There is drop hanger 4 the one end below of sticking up bar 2, at this contact block 5 is housed above the end.The upper end of extension spring 6 is connected with the other end that sticks up bar 2, and its lower end is contained on the base 3.A distance is provided with microswitch 7 with matching above contact block 5, in the bottom of microswitch 7 contact 8 is arranged.Hang infusion bottle 9 on the drop hanger 4, microswitch 7 is joined with the sound and light alarm circuitry.

When infusion bottle 9 fills with medicinal liquid,, make contact block 5 and contact 8 throw off and keep certain distance because its action of gravity and extension spring 6 are kept in balance.Along with the carrying out of transfusion, amount of liquid medicine reduces gradually, tilts at the effect of extension spring 6 bar 2 that has a downwarp, and contact block 5 is progressively near contact 8.When amount of liquid medicine reduced to prescribed limit, contact block 5 touched contact 8, starts microswitch 7, and the green light breath that is contained in the warning device of dispensary goes out, and red light is shinny, and acoustical generator sends alarm sound.

Claims

1, a kind of infusion alarm, formed by sticking up bar, support column, base and acousto-optic warning device, support column upper end with stick up bar and become that hinge is connected, the lower end is connected with base, it is characterized by sticking up suspension gear, contact block and spring are housed on the bar, and be provided with the microswitch that matches with contact block.

2, infusion alarm according to claim 1 is characterized in that described suspension gear is drop hanger or suspension ring, is contained in the end below of sticking up bar, contact block be contained in stick up bar this end above, the microswitch of cooperation with it is equipped with in a distance above contact block.
