In the utility model, the inner part of a main body is provided with a PCB circuit board which is supplied with electricity by a battery which is installed in a battery box of the main body; the inner part of the main body is also provided with a compression spring which is arranged in a containing groove of the main body; one end of the compression spring is supported and pressed on the end part of the containing groove, the other end of the compression spring is connected with a hanging hook exposed outside the main body, the compression spring is provided with a guiding piece which is used for switching on a circuit of a buzzer on the PCB circuit board on the outer edge of one end which is connected with the hanging hook; the main body is provided with an adjusting screw rod matched with the guiding piece; the adjusting screw rod is connected with the circuit of the buzzer by a conducting wire. The utility model uses can switch on the circuit of the buzzer utilizing the telescopic principle of the compression spring, and thereby, the buzzer can automatically send out alarming sound for reminding users to draw infusion needles in time for preventing vein blood returning of patients and other situations after transfusion completed.
Description
Technical field:
This utility model relates to the auxiliary facilities technical field of medical apparatus and instruments, refers in particular to a kind of transfusion bottle alarm that is used to infuse.
Background technology:
Venous transfusion is the treatment means that each medical institutions uses always the disease patient, and medicinal liquid is by tube for transfusion, drop speed display tube, syringe needle input human vein, to reach therapeutic purposes during transfusion.Yet in practical operation, because the medical worker is for the moment busy or forget, and the patient can not in time extract injection needle when losing consciousness " deep sound sleep " after medicinal liquid is totally lost, cause patient's vein blood back thus, and produce inconvenience and problem therefrom.
Summary of the invention:
The purpose of this utility model is to provide a kind of transfusion bottle alarm that can sound the alarm automatically after medicinal liquid is totally lost.
This utility model is achieved by the following technical solution: be provided with a compression spring in the body, this compression spring is arranged in the holding tank of body, and there is an end to press on the end of holding tank, and the other end of compression spring is connected with a hook that exposes to body, one end outer rim of the coupling hook of compression spring is provided with the guide card that is used to touch the circuit that leads to the buzzer on the PCB circuit board, cooperate guide card to be provided with adjusting screw(rod) on body, this adjusting screw(rod) is connected with the circuit of buzzer by lead.
Described hook is formed in one with the compression spring, and the extension arm of hook is through the centre bore of compression spring; Described body is covered by upper and lower two lids and is formed by connecting, simultaneously on the body, be provided with a hanged hook with the hook opposite end.
When this utility model cooperates transfusion bottle to use, utilize compression telescopic spring principle, can reach the circuit that touches logical buzzer, thereby when transfusion was finished, buzzer sent chimes of doom automatically, so that remind user in time to extract infusion needle, prevent situation generations such as patient's vein blood back, guarantee personal safety.
Description of drawings:
Accompanying drawing 1 is a schematic perspective view of the present utility model;
Accompanying drawing 2 is another visual angle schematic perspective view of the present utility model;
Accompanying drawing 3 is a lid portion inside structural representation on this utility model;
Accompanying drawing 4 is a lid portion inside structural representation under this utility model;
Accompanying drawing 5 is the embodiment circuit diagram of this utility model.
The specific embodiment:
See accompanying drawing 1～5, this utility model includes body 1, and body 1 is covered by upper and lower two lids and is formed by connecting, and is provided with a PCB circuit board 2 in the body 1, and PCB circuit board 2 is by the battery powered in the battery case 11 that is installed in body 1.Also be provided with a compression spring 3 in the body 1, compression spring 3 is arranged in the holding tank 12 of body 1, and has an end to press on the end of holding tank 12, and the other end of compression spring 3 is connected with a hook 4 that exposes to body 1.Hook 4 is formed in one with compression spring 3, and link up with 4 extension arm centre bore through compression spring 3, one end outer rim of the coupling hook 4 of compression spring 3 is provided with the guide card 5 that is used to touch the circuit that leads to the buzzer on the PCB circuit board 2, cooperate guide card 5 to be provided with adjusting screw(rod) 13 on body 1, adjusting screw(rod) 13 is connected with the circuit of buzzer by lead.On the body 1, with the hook 4 opposite ends be provided with a hanged hook 14.
During use, earlier alarm is hung on the appropriate location by the hanged hook on the body 1 14, required transfusion bottle is hung on the hook 4 that is arranged on the alarm body 1 again; At this moment, at the action of gravity lower compression spring 3 of transfusion bottle by an end of its coupling hook 4 along holding tank 12 to lower compression to a certain degree, guide card 5 also moves down thereupon and is positioned at the below of adjusting screw(rod) 13; Then adjusting screw(rod) 13 is set in the scale position of the specification bottle that hangs, subsequently on and off switch is opened energized, PCB circuit board 2 is started working.In infusion process, along with the medicinal liquid in the transfusion bottle constantly reduces, the gravity of effect compression spring 3 reduces thereupon, compression spring 3 is upheld gradually, when transfusion is near completion, be arranged on the guide card 5 of compression on the spring 3 and touch the corresponding site of adjusting screw(rod) 13, promptly touch the circuit of the buzzer on the logical PCB circuit board 2 with the extension of compression spring 3.Warning circuit is started working, and the alarm signal of IC (SN67010) output promotes the speaker SP sound that gives the alarm, thereby reminds user in time to extract infusion needle after audion (S9013) amplifies, and prevents patient's vein blood back.This utility model is applicable to the transfusion bottle of 500ML, 250ML and 100ML specification, only needs in use that for different transfusion bottles adjusting screw(rod) 13 is set in corresponding specification bottle scale and gets final product.The time spent does not belong to 0 with adjusting screw(rod) 13, powered-down switch or the batteries in the battery case 11 are taken out.
