Description

Infusion alarm

This utility model relates to a kind of infusion alarm, belongs to the adnexa of medical infusion apparatus.

Existing medical gravity transfusion device, when transfusion, whether nurse or patient will observe in the infusion bottle will fail sky, the nurse could in time stop transfusion or change infusion bottle, particularly work as a plurality of severe cases and need transfusion in continuous several days, whether the infusion bottle that the nursing staff needs in time to observe each patient will fail sky, and in time dispose.One is careless slightly, and serious consequence will take place the defeated sky of infusion bottle.

The purpose of this utility model is in order to ensure the safety design a kind of infusion alarm of patient when infusing.Particularly the critical patient is being infused a few days continuously, the nursing staff is tired or when looking after other patients and can not in time observe the transfusion situation, can shift to an earlier date and in time send alarm signal, reminds nursing staff's infusion bottle to be about to drip off, should in time dispose, thereby reach the assurance safe infusion.

The technical scheme that achieves the above object is as follows:

Infusion alarm comprises casing, base (13), the fulcrum (2) that it is characterized in that lever (1) is positioned on the support (15) of base (13), lever (1) is respectively equipped with infusion bottle hook (8 in the end on the both sides of fulcrum (2), 9) with the end face (10) that contacts with microswitch (16) in the warning circuit, compression spring (11) is positioned between support (15) and the infusion bottle hook (8), compression spring (11) two ends are separately fixed on lever (1) and the base (13), warning circuit comprises battery (26), its positive pole connects the normally-closed contact input (28) and the normally opened contact input (29) of microswitch (16), the normally-closed contact outfan (22) of microswitch is connected with green indicating lamp (24), the normally opened contact outfan (23) of microswitch is connected green indicating lamp (24) with red led (25) with buzzer (12), another terminals of red led (25) and buzzer (12) are connected with the battery supply negative pole.

This utility model infusion alarm not only can guarantee the patient safety transfusion, and simple in structure, and expense is low, is convenient to be installed on the drip stand, infusion bottle is hung on the scalable hook of infusion alarm get final product.

Elaborate in conjunction with the accompanying drawings below by embodiment.

Fig. 1 is the structural representation and the circuit diagram of infusion alarm;

Fig. 2 is another embodiment of the present utility model;

Fig. 3 is that infusion alarm is installed in the sketch map on the drip stand.

Fig. 1 is this utility model infusion alarm, mainly is made up of leverage and warning circuit.The fulcrum 2 of the lever 1 in the leverage is positioned on the support 15 of base 13, and lever 1 is provided with compression spring 11,

infusion bottle hook

8,9 successively on one side of support 15 (being right-hand among the figure).Lever 1 contacts with microswitch 16 in the warning circuit at the end of the another side (being left among the figure) of support 15.

The power supply AC/DC of this utility model infusion alarm, 220 volts of alternating current power supplys, connect transformator 18 through on and off switch 17 and be depressurized to 3 volts of connection contactor coils 19, catalyst has two normally opened

contacts

20,27, normally-closed contact 21 its normally opened contact 20 1 ends and red leds 25, green indicating lamp 24, buzzer 12 is connected with battery cathode, one end of normally opened contact 27 is connected with the input 29 of the normally opened contact of the normally-closed contact input 28 of microswitch 16 and microswitch and the other end of normally-closed contact 21, the other end of normally-closed contact 21 is connected with battery supply is anodal, green indicating

lamp

24,22 ends of the normally-closed contact of the other end of red led 25 and buzzer and

microswitch

16,23 ends of normally opened contact connect.

The operation principle of infusion alarm is as follows, when infusion bottle hangs over infusion bottle hook 8, in the time of on 9, the infusion bottle that fills transfusion adds microswitch 16 to the moment of lever 1 fulcrum 2 spring force to the moment of lever 1 fulcrum 2 greater than the moment of compression spring to fulcrum 2, make lever 1 around fulcrum 2 clockwise directions rotations (by shown in Figure 1), the normally closed

interlock

22,28 of microswitch is connected, with battery 26 power supplies, during perhaps with 220 volts of Alternating Current Power Supply energized switches 17, the normally opened contact of catalyst 16 (20,27) closure, normally-closed contact 21 disconnects, at this moment green indicating lamp 24 is bright, red led 25 does not work, and buzzer 12 also cuts off the power supply, and is the normal infusion state.

When the transfusion in the infusion bottle is about to be totally lost, weight saving, the spring force that its moment to the fulcrum 2 of lever 1 adds microswitch 16 to the moment of the fulcrum 2 of lever 1 less than the moment of compression spring to fulcrum 2, lever 1 counterclockwise rotates around fulcrum, lever 1 left side end face 10 is depressed microswitch 16, make the normally-closed contact 22 of microswitch, 28 disconnect, green indicating lamp 24 goes out, when being reduced to, the transfusion in the infusion bottle need to remind the nurse to change bottle or when stopping to infuse liquid level when disposing, it is bright that lever 1 is depressed into connection normally opened contact (23,29) red led 25 with microswitch 16, and buzzer 12 is reported to the police.

Surplus how many palpuses of transfusion remind the nurse to dispose in the infusion bottle, can regulate transfusion hook distance size from balance pivot on lever 1 as required, can require to regulate according to the nurse, infusion bottle hook upper end can be moved on lever, and be fixed tightly on the lever with screw, can be carved with on the lever to regulate and use scale, so that regulate.Lever 1 can adopt insulant.

When the alternating current power supply normal power supply, during on and off switch 17 closures, contactor coil 19 has electric current to pass through, and normally-closed contact 21 is disconnected, and normally opened

contact

20,27 is connected.

When alternating current power supply is cut off the power supply, contactor coil 19 outages, normally opened

contact

20,27 disconnects, and normally-closed contact 21 is connected, and makes battery powered, and infusion alarm still keeps operate as normal.

Buzzer 12, available music doorbell circuit or similar reversing automobile sound circuit substitute, and can reach music or language alarm effect.

This utility model infusion alarm is provided with the adjustable stops 14 that is fixed on the base 13 between the contact end face 10 of support 15 and lever 1, prevent that

infusion bottle hook

8,9 is sagging too much.Between compression spring 11 and infusion bottle hook 8, be provided with another adjustable stops 4 that is fixed on the base 13, prevent the excessive part that damages microswitch 16 of elastic force owing to compression spring 11.
