Abstract

The utility model relates to a safety alarm for an intravenous infusion controller, which can ensure the vein safety and can make the intravenous infusion stop automatically. The utility model comprises a spring, a reed switch, an alarm, a control device and a control circuit of safety alarm; one end of the spring is connected with a screw which is fixed on the shell and the other end of the spring is connected with a hook which is provided with a magnet. In the processes of intravenous infusion, an infusion bottle (bag) is hung on the hook and the spring can be stretched by the gravity of the physic liquor; with the reduction of the physic liquor, the spring is shortened and the positions of the hook and magnet are changed; when the magnet is at the closed position of the reed switch, the reed switch is closed to switch on the alarm control circuit, and the alarm alarms and the control device clamps the infusion pipe tightly; so the intravenous infusion is stopped.

Description

Safety alarm for intravenous infusion controller

This utility model is a kind of venous transfusion security alarm control device that guarantees venous transfusion safety.After the infusion bottle inner liquid medicine is totally lost when venous transfusion, flow out the outer or air of human body by syringe needle and enter the phenomenon that human body injures transfusion person's health or life security as not extracting infusion needle will take place by transfusion person venous blood by syringe needle, at present usually the method that adopts is to watch medicinal liquid face in the infusion bottle attentively by monitoring person or transfusion person, when being totally lost, finishes medicinal liquid transfusion work, because of the longer monitoring person of transfusion time or transfusion person gruelling, if above-mentioned dangerous phenomenon still can take place in carelessness.

The purpose of this utility model is that a kind of venous transfusion security alarm control device that guarantees venous transfusion safety will be provided, and it can prevent the generation of above-mentioned dangerous phenomenon effectively.

The purpose of this utility model is achieved in that the spring that is connected with hook with screw is subjected to the effect of medicinal liquid gravity to change length the magnet positions in the hook is changed, and makes the tongue tube closure, alarm and control circuit work.During venous transfusion infusion bottle (bag) is hung in the hook, the Magnet that gravity elongates in the hook at this moment spring can not make the tongue tube closure, when transfusion will finish, because the infusion bottle inner liquid medicine reduces the contraction in length that makes spring, when the arrival of the Magnet in the hook makes the position of tongue tube closure, the tongue tube closure, connect circuit, alarm control circuit work, alarm equipment alarm, controller clamps tube for transfusion, stops transfusion simultaneously.

This utility model is not subjected to the restriction of amount of infusion size, and the weight according to infusion bottle during use is adjusted screw, Magnet is in when transfusion finishes the position of tongue tube closure is got final product.

Concrete structure of the present utility model is drawn by following embodiment and accompanying drawing thereof, Fig. 1 is the plane graph according to the venous transfusion security alarm control device that the utility model proposes, this device comprises spring (1), screw (2), hook (3), Magnet (4), alarm control circuit (5), tongue tube (6), switch (7), power supply (8), alarm (9), controller (10), shell (11) is as shown in the figure: screw (2) spring (1) and hook (3) link together in order from top to bottom, screw (2) is fixed on the shell (11), Magnet (4) is installed in the hook (3), hook (3) and tongue tube (6) be arranged in parallel, opening switch (7) energized (8) back alarm control circuit (5) does not work, tongue tube (6) is in normally open, when the position of Magnet (4) is changed to by the medicinal liquid gravity effect and during the position consistency of tongue tube (6), tongue tube (6) closure, alarm control circuit (5) work, alarm (9) is reported to the police, controller (10) action simultaneously, clamp tube for transfusion, the transfusion work safety stops.

Venous transfusion security alarm controller has alleviated monitoring person's workload and transfusion person's stress, and the venous blood of avoiding transfusion person is taken place during end-of-job by transfusion flows out external by syringe needle, or air has guaranteed the safety of venous transfusion work by the dangerous phenomenon generation that syringe needle enters human body.

Claims
