CN2274965Y - Automatic alarm for infusion safety - Google Patents

Abstract

The utility model relates to an automatic alarm for infusion safety, which comprises an adjustable gravity travel switch, wherein, the gravity travel switch is connected with an alarm circuit, and the upper and the lower parts of the gravity travel switch are respectively provided with a hook. The utility model has the advantages of simple structure, convenient use and safe alarm, and can avoid the accident threat occurring in infusion.

Description

The safe autoalarm of infusing

This utility model belongs to armarium, specifically is meant the safe autoalarm of a kind of transfusion.

Hospital is a kind of very general treatment means to patient infusion at present, but because a variety of causes, what the most easily go wrong in infusion process is after medicinal liquid is totally lost, and still fails to do timely processing, and causes malpractice, and bring misery to patient.Its main cause is: the fluid delivery apparatus of hospital's use does not at present have warning function, falls asleep as patient, does not have the entourage at one's side again, malpractice hidden danger then very easily occurs.

Goal of the invention of the present utility model be disclose a kind of when medicinal liquid is about to be totally lost, the safe autoalarm of transfusion capable of automatic alarm.

The technical solution that realizes goal of the invention of the present utility model is as follows.One adjustable gravity travel switch connects a warning circuit on the gravity travel switch, the upper and lower suspension hook of all being with of gravity travel switch.When the hook of gravity travel switch hangs on the drip stand, the infusion bottle that plays on the following suspension hook, when medicinal liquid was reduced to a specified weight, travel switch starts warning circuit reported to the police, and medical personnel then can deal with rapidly.

This utility model is simple in structure, and is easy to use, and it is safe and reliable to report to the police, the accident potential in the time of can avoiding occurring infusing.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model;

Fig. 3 is another circuit theory diagrams of the present utility model.

Referring to Fig. 1-Fig. 3, structure of the present utility model is as follows, and an adjustable gravity travel switch connects a warning circuit on the gravity travel switch, and the gravity travel switch all is with a suspension hook 2 up and down.The structure of above-mentioned gravity switch is all to have a metal cartridge 3, two metal cartridges 3 to be provided with a spring 4 on two suspension hooks 2, establishes a warning circuit 1 on last metal cartridge, and warning circuit 1 is connected with two metal cartridges.When the medicinal liquid in the suspension hook infusion bottle of hanging oneself reduced gradually instantly, under the pulling force effect of spring, two metal cartridges 3 moved closer to, when medicinal liquid reduces to a certain amount of, and 3 contacts of two metal cartridges, then guide alarm circuit 1, sends chimes of doom.

Above-mentioned warning circuit 1 as shown in Figure 2, the structure of warning circuit 1 is that the power supply back of connecting with K switch is in parallel again with a placed in-line LED and resistance R, connects a message device LB and gravity travel switch again and the loop that constitutes.When K switch is closed, sound can take place in the message device, LED is still luminous simultaneously, but whether check circuit is working properly, after hanging up infusion bottle, the gravity travel switch disconnects, LED is still shinny, transports to when a certain amount of when medicinal liquid, and the gravity travel switch is connected, the message device sends sound, reminds patient and medical personnel to note.

When there is nurse's paging system in the ward, above-mentioned warning circuit 1 as shown in Figure 3, be provided with socket K2 in above-mentioned warning circuit, the effect of K2 is when a plug inserts, and then warning circuit is connected with nurse's call alarm system, when the conducting of gravity travel switch, warning system works simultaneously, and reminding the nurse on duty of nurse station is that berth need deal with, after transfusion finishes, then can remove, and not disturb the operate as normal of nurse's paging system.

Above-mentioned last metal cartridge 3 is dynamically connected for drawing together with the upper end of spring, adjusting the distance between two metal cartridges, with the use of the medicinal liquid bottle that adapts to different size.

Claims (4)

1, the safe autoalarm of a kind of transfusion is characterized in that an adjustable gravity travel switch, connects a warning circuit on the gravity travel switch, and the gravity travel switch all is with a suspension hook up and down.

2, by the described autoalarm of claim 1, it is characterized in that the gravity travel switch structure is all to have a metal cartridge on two suspension hooks, two metal cartridges are provided with a spring, establish a warning circuit on last metal cartridge, and warning circuit is connected with two metal cartridges.

3, by claim 1 or 2 described autoalarms, it is afterwards in parallel again with a placed in-line LED and resistance R that the structure that it is characterized in that warning circuit is that a power supply is connected with K switch, connects a message device LB and gravity travel switch again and constitute the loop.

4, by the described autoalarm of claim 3, it is characterized in that in above-mentioned warning circuit, being provided with socket K2.
