Abstract
The utility model relates to a transfusion alarm device consisting of a response device and an alarm circuit. The response device comprises a plastic barrel which is connected in series with an infusion tube above an infusion drip barrel, a sealed working bubble is fixed in the plastic barrel, and a response element in the working bubble is connected with the alarm circuit. The transfusion alarm device provided by the utility model can give off indicating sound when the drug fluid in the infusion bottle is going to be used up to remind the patient or accompanying personnel of changing dressing or pulling out the needle for finishing the treatment, thereby avoiding unnecessary medical hazard, and achieving the aim of a disburdened and safe treatment.
Description
Technical field
This utility model relates to a kind of medical auxiliary equipment, particularly a kind of infusion alarm.
Background technology
At present, hospital is usually due to illness people and nurse personnel's carelessness in the infusion process of curing the disease, and the cutout of infusion process herb liquid occurring can not in time change liquid, causes patient's blood back tube for transfusion or tube for transfusion to enter air, causes the appearance of malpractice.
The utility model content
The purpose of this utility model is to provide a kind of safe and reliable infusion alarm.
The purpose of this utility model is achieved through the following channels: infusion alarm is made up of reaction unit and two parts of warning circuit, described reaction unit comprises a plastic barrel on the tube for transfusion that is serially connected in transfusion drop tube top, the plastic barrel internal fixation is equipped with the work bubble of a sealing, this work bubble top is equipped with exhaustor and connects the outside from the plastic barrel roof, the bottom of work bubble is telescopic rubber elastic membrane, rubber membrane is connected and fixed by the inner moving contact metal film of connecting rod and work bubble, the shaft of connecting rod passes the centre bore of quiet contact metal film, the two ends up and down of shaft are fixedly rubber membrane and moving contact metal film respectively, quiet contact metal film is fixed on the work bubble medial wall, moving contact metal film and quiet contact metal film be respectively by two wires circuit taking alarm, and the metal wire of overcoat insulating protective layer is to pass the work bubble of encapsulation process and the access warning circuit; Described warning circuit is formed by connecting by battery BT, music IC, audion VT and speaker BL.Add delay electronic switch K in the warning circuit.
This utility model infusion alarm when using up, can send prompting sound at transfusion medicine bottle inner liquid medicine, reminds the patient or the entourage in time changes dressings or dial pin and finish treatment, avoids unnecessary medical treatment harm, reaches purpose relieved, safe treatment.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail:
Fig. 1 is this utility model structural representation.
The specific embodiment
As shown in Figure 1, this utility model infusion alarm is made up of reaction unit and two parts of warning circuit, described reaction unit comprises a plastic barrel 1 on the tube for transfusion 6 that is serially connected in transfusion drop tube top, plastic barrel 1 internal fixation is equipped with the work bubble 2 of a sealing, this work steep 2 tops be equipped with superfine exhaustor 9 from plastic barrel 1 roof connect the outside, exhaustor 9 can be with work bubble 2 because of rubber membrane 3 motions formation flow air discharge work bubble 2, the bottom of work bubble 2 is telescopic rubber elastic membrane 3, rubber membrane 3 can be with the lifting of medicinal liquid liquid level up and down, rubber membrane 3 is connected and fixed by the moving contact metal film 5 of connecting rod 4 with work bubble 2 inside, the shaft of connecting rod 4 passes the centre bore of quiet contact metal film 7, the two ends up and down of shaft are fixedly rubber membrane 3 and moving contact metal film 5 respectively, quiet contact metal film 7 work of being fixed on are steeped on 2 medial walls, moving contact metal film 5 and quiet contact metal film 7 be respectively by two wires, 8 circuit taking alarm, and the metal wire 8 of overcoat insulating protective layer is to pass the work bubble 2 of encapsulation process and insert warning circuit; Described warning circuit is formed by connecting by battery BT, delay electronic switch K, music IC, audion VT and speaker BL.
The work process of this device is as follows: the medicinal liquids in the tube for transfusion 6 flow through plastic barrel 1, transfusion drop tube after injection needle take turns in the human body, when being full of medicinal liquid in the plastic barrel 1, plastic barrel 1 built-in work bubble 2 also is immersed in the medicinal liquid simultaneously, the telescopic rubber elastic membrane 3 in the bottom of work bubble 2 is owing to be subjected to the buoyant support of medicinal liquid, to move contact metal film 5 by connecting rod 4 upwards pushes away, the warning circuit of this moment is not connected, and can not produce warning; When plastic barrel 1 inner liquid medicine reduces the liquid level reduction, rubber elastic membrane 3 lacks the buoyant support of medicinal liquid and descends, connecting rod 4 on the rubber elastic membrane 3 will move contact metal film 5 and pull down, when medicinal liquid does not have, moving contact metal film 5 is communicated with the quiet contact metal film 7 that the work that is fixed on is steeped in 2, thereby activate warning circuit work, the music tip sound of music IC is sent by speaker BL after amplifying in the warning circuit, reminds patient and medical worker in time to change dressings.
