Abstract

The utility model relates to a medical transfusion alarm device, which is hung between a transfusion shelf and a transfusion bottle. A movable spring (3), a magnet (14), and a hanging hook (15) are arranged in a hanging tube (4). An alarm box (5) which is provided with an alarm circuit and a dry reed tube. Alarm positions can be adjusted up and down along the hanging tube according to transfusion bottles which are used with different volumes. When the transfusion of medicine liquid almost finishes, the magnet retracts following a spring. The dry reed tube reaches sufficient magnetic force and closes. An alarm circuit is switched on, and alarm signals are sent out. The utility model prevents medical staff's and patients' trouble and pain because a transfusion bottle is empty, and relieves nursing staff's fatigue because the surplus of medicine needs observing from time to time.

Description

Infusion alarm

This utility model relates to a kind of medical transfusion alarm device, especially can prevent the alarm of infusion bottle giving drugs into nose drop sky.

At present, used infusion set in the medical treatment is infusion bottle to be hung be hung on the drip stand, infuses by the transfusion device that is inserted on the transfusion bottle stopper then.Its weak point is, often because transfusion time is long, the entourage causes transfusion device air inlet or blood back overlong time to cause blood clotting because of tired or carelessness make infusion bottle drip sky, unavoidably to handle again, increase medical personnel's working strength and patient's misery.

The purpose of this utility model provides a kind of infusion alarm, sends warning when it can the medicinal liquid in infusion bottle be about to drip off.

The purpose of this utility model is achieved in that transfusion device is inserted in the transfusion bottle stopper, and infusion bottle and drip stand flexibly connect by infusion alarm.Infusion alarm is made up of the elastic and the warning circuit that detect infusion bottle weight, during the transfusion beginning, the elastic generation deformation that is flexibly connecting with infusion bottle, along with the carrying out of transfusion, infusion bottle weight reduces gradually, when the bottle inner liquid medicine is about to drip off, along with resetting of elastic, utilization makes non-contacting electric contact closure with the magnet of elastic synchronization action, thereby connects warning circuit automatically, sends alarm signal.

Such scheme is owing to adopting elastic, provide detection signal with the magnet of elastic synchronization action with the non-contacting electric contact of magnet, therefore simple in structure, report to the police accurate, good reproducibility.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a vertical section of the present utility model structural map.

Fig. 2 is the I-I cutaway view of Fig. 1.

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

Hanging swing pipe (4) among the figure is hung on the drip stand by hanging lifting hole(eyelet) (1) extension, infusion bottle is hung and is hung on the hanging hook (15), spring (3) links to each other by brace (2) with extension swing pipe (4), brace (2) is fixedly clamped in the flat part of hanging swing pipe (4) top, brace (2), spring (3), hanging hook (15) is fixedly connected, magnet (14) is fixed on the spring (3), its medi-spring (3) and magnet (14) can move up and down in hanging swing pipe (4) freely, the limited cover (7) of middle perforate is fixed on the lower end that hangs swing pipe (4), and it is limited to spring (3) in its elastic limit; Battery (6), tongue tube (8), draw socket (9) outward, display lamp (10), switch (11), sound circuit plate (12), loudspeaker (13), standing screw (16), hold-down nut (17) all is contained in the warning box (5), there is one in the middle of the warning box (5) than hanging the big slightly hole of swing pipe (4) external diameter, by this hole warning box (5) is sleeved on outside the extension swing pipe (4), and warning box (5) is fastened on the outer wall of hanging swing pipe (4) with standing screw (16), when unscrewing standing screw (16), warning box (5) can move up and down outside hanging swing pipe (4), so that report to the police adjusting to the infusion bottle of different capabilities the time accordingly, hang swing pipe (4) and need to adopt the material that can not be magnetized with warning box (5); The middle hole wall (18) that tongue tube (8) is close to warning box (5) is parallel to that to hang swing pipe (4) fixing, drawing independent other armarium to the outside of socket (9) outward provides standby warning contact, adopts a kind of speech chip (KD-9300) that alarm sound is provided in the present embodiment.This infusion alarm work process is as follows: the infusion alarm extension is hung between drip stand and the infusion bottle, spring (3) is stretched, warning box (5) is transferred to the alert locations corresponding with the infusion bottle capacity [different alert locations labellings marks in advance according to the infusion bottle of different capabilities] on extension swing pipe (4), open switch (11), display lamp (10) is bright, the expression infusion alarm is in duty, when carry out of infusion bottle along with transfusion, when its weight is reduced to a certain degree, it is up that spring (3) is being with magnet (14) to shrink, when the bottle inner liquid medicine is about to drip off, tongue tube (8) just in time is subjected to the enough magnetic force of the up and magnet (14) that comes and closure, the warning circuit of Fig. 3 is connected, also closed simultaneously by drawing the standby warning contact that socket (9) outwards provides outward, send the continuous alarm signal, till medical care or entourage turn off switch (11).
