Abstract
The utility model discloses a transfusion automatic warning device, comprising a supporting device and a horizontal crossbar, wherein the horizontal crossbar is positioned at the top end of the supporting device and is fixedly connected with the supporting device; a spring is hanged downward on the horizontal crossbar; the lower end of the spring is fixed with a metal contact; a position switch is arranged at one side of the spring near the upper end of the supporting device; the metal contact and the position switch are positioned on the same vertical plane; and the position switch and a sounding device fixed on the supporting device and a power supply are connected in series. The transfusion automatic warning device lead an infusing bag to be hanged on a bracket by the spring, utilizes the principle that the spring is expanded with the change of the weight of the infusion bag so as to control the contact of the metal contact and the position switch, thus achieving the function of automatic waning after the completion of the transfusion.
Description
Technical field
This utility model relates to a kind of autoalarm, particularly a kind of automatic alarm for transfusion.
Background technology
In the time of our transfusion now, when transfusion will finish, if the untimely doctor of informing extracts syringe needle or increases medicinal liquid, blood then can flow back in the tube for transfusion, brings unnecessary damages to us, went back entail dangers to life when serious.
Summary of the invention
Goal of the invention of the present utility model is: the problems referred to above at existing infusion set exists provide a kind of device that can report to the police automatically when transfusion finishes.
Goal of the invention of the present utility model, realize by implementing following technical proposals:
A kind of automatic alarm for transfusion, comprise bracing or strutting arrangement and horizontal cross bar, horizontal cross bar is positioned at the bracing or strutting arrangement top and fixedlys connected with bracing or strutting arrangement, it is characterized in that: on horizontal cross bar, hang with spring straight down, the lower end of spring is fixed with metal contact, near spring one side travel switch is arranged in the bracing or strutting arrangement upper end, metal contact and travel switch are positioned on the same perpendicular, and described travel switch is connected in series with the sound-producing device and the power supply that are fixed on the bracing or strutting arrangement.
A kind of automatic alarm for transfusion described in the utility model, its bracing or strutting arrangement is made of expansion link and sleeve pipe, and expansion link is by clamp device and telescopic joint.
Advantage of the present utility model is: by transfusion bag is suspended on the support with spring, flexible principle is controlled contacting of metal contact and travel switch with the transfusion bag weight change to utilize spring, after metal contact and travel switch connection, will start alarm device, send alarm sound, remind the doctor to change medicine, infuse when finishing thereby reach, automatically the function of reporting to the police.
Description of drawings
Fig. 1 is the structural representation of a kind of automatic alarm for transfusion of this utility model.
Labelling among the figure: 1 is horizontal cross bar, and 2 is spring, and 3 is metal contact, and 4 is travel switch, and 5 is sound-producing device, and 6 is expansion link, and 7 is sleeve pipe, and 8 is clamp device, and 9 is transfusion bag.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is done detailed explanation.
As shown in Figure 1, this utility model automatic alarm for transfusion, comprise bracing or strutting arrangement and horizontal cross bar 1, horizontal cross bar 1 is positioned at the bracing or strutting arrangement top and fixedlys connected with bracing or strutting arrangement, on horizontal cross bar 1, hang with spring 2 straight down, transfusion bag hangs on the spring, the lower end of described spring 2 is fixed with metal contact 3, near spring 2 one sides travel switch 4 is arranged in the bracing or strutting arrangement upper end, described travel switch 4 is in normal off and opens state, and metal contact 3 and travel switch 4 are positioned on the same perpendicular, described travel switch 4 is connected in series with the sound-producing device 5 and the power supply that are fixed on the bracing or strutting arrangement, and described sound-producing device is commercial product.The variation of liquid weight can cause the variation of spring length in the transfusion bag, and the liquid in transfusion bag has flowed soon and made, and spring shrinks, and metal contact and travel switch are connected, and start alarm device, send alarm sound, in time remind the doctor to change medicine; After transfusion bag is injected liquid, the spring elongation, metal contact and travel switch break away from, and stop to report to the police.
Described bracing or strutting arrangement is made of expansion link 6 and sleeve pipe 7, and expansion link 6 is connected with sleeve pipe 7 by clamp device 8, like this can be according to patient or environmental requirement, and the height of free adjustment transfusion, simple and convenient.
