Abstract
The utility model provides an infusion alarm device with a liquid level detection function, which comprises a needle head, a base fixed with the needle head, and an infusion tube communicated with the needle head. The infusion alarm device is characterized in that the alarm device comprises a clip and an alarm circuit; an upper metal sheet and a lower metal sheet are sequentially arranged on the needle head from top to bottom; a left metal sheet and a right metal sheet which are respectively connected with the upper metal sheet and the lower metal sheet are arranged on the base; a first metal sheet and a second metal sheet which are matched with the left metal sheet and the right metal sheet are respectively arranged on the clip; and the alarm circuit is connected with the first metal sheet and the second metal sheet. The infusion alarm device effectively achieves an alarm effect during the infusion process, has the advantages of simple structure and low cost, and is convenient to use.
Description
Technical field
This utility model relates to a kind of infusion alarm with level detection function, in particular, relates in particular to a kind of infusion alarm with level detection function simple in structure.
Background technology
Existing infusion alarm is varied, and the principle of employing also is not quite similar, the employing infrared detection principle that has, the employing pressure detecting principle that has; But the circuit structure of existing infusion alarm is comparatively complicated, and not only making is difficult, cost is high but also damage easily.
Summary of the invention
This utility model has overcome the shortcoming of above-mentioned technical problem, and a kind of infusion alarm with level detection function simple in structure is provided.
For achieving the above object, this utility model has adopted following technical scheme:
Infusion alarm with level detection function of the present utility model, base that comprises syringe needle, fixes with syringe needle and the tube for transfusion that is connected with syringe needle, it is characterized in that: described alarm device comprises clip and warning circuit, be disposed with sheet metal and following sheet metal on the described syringe needle from top to bottom, described base is provided with respectively left sheet metal and the right sheet metal that is connected with following sheet metal with last sheet metal; Described clip is provided with first sheet metal and second sheet metal that matches with left sheet metal and right sheet metal respectively; Described warning circuit is connected with second sheet metal with first sheet metal.After syringe needle extend in the infusion bottle, because this moment, the liquid levels height in the infusion bottle was very high, the last sheet metal that is arranged on the syringe needle just was in conducting state with following sheet metal; Along with the liquid level of liquid in the infusion bottle constantly descends, when liquid level drops to when going up under the sheet metal, the conducting state between last sheet metal and the following sheet metal just becomes off-state, and then the detection by warning circuit, the realization warning function.Clip is set, and on base, left sheet metal and the right sheet metal that matches with clip is set, help realizing the dismounting of clip, more convenient the use.
Infusion alarm with level detection function of the present utility model, described warning circuit comprises control circuit, speaker and power supply.Control circuit is used for the conducting state of last sheet metal with following sheet metal detected, and realizes corresponding warning function.
Infusion alarm with level detection function of the present utility model, described syringe needle are non-conductive material.Guarantee that syringe needle is non-conductive material, could guarantee to carry out conducting by the liquid in the infusion bottle between sheet metal and the following sheet metal, and can not pass through the syringe needle conducting.
The beneficial effects of the utility model: this utility model is by being provided for detecting in the infusion bottle sheet metal and following sheet metal on the liquid level on syringe needle, and be provided with the warning circuit that is used to detect conducting state between sheet metal and the following sheet metal that to dismantle, realized warning effectively, had advantage simple in structure, easy to use and that cost is low infusion process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Among the figure: 1 syringe needle, 2 bases, 3 tube for transfusions, sheet metal on 4,5 times sheet metals, 6 left sheet metals, 7 right sheet metals, 8 clips, 9 first sheet metals, 10 second sheet metals, 11 warning circuits.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, provided structure principle chart of the present utility model, it comprises syringe needle 1, base 2, tube for transfusion 3, last sheet metal 4, following sheet metal 5, left sheet metal 6, right sheet metal 7, clip 8, and shown base 2 fixes with syringe needle 1, and tube for transfusion 3 unprecedentedly is connected with syringe needle 1 inside; Last sheet metal 4 and following sheet metal 5 from top to bottom are arranged on the outer surface of syringe needle 1.Left side sheet metal 6 and right sheet metal 7 are arranged on the base 2, and are connected with following sheet metal 5 with last sheet metal 4 respectively by lead.After syringe needle 1 extend in the infusion bottle, because this moment, the liquid levels height in the infusion bottle was very high, the last sheet metal 4 that is arranged on the syringe needle 1 just was in conducting state with following sheet metal 5; Along with the liquid level of liquid in the infusion bottle constantly descends, when liquid level drops to when going up under the sheet metal 4, the conducting state between last sheet metal 4 and the following sheet metal 5 just becomes off-state, and then the detection by warning circuit, the realization warning function.
As shown in Figure 2, circuit theory diagrams of the present utility model have been provided, it comprises sheet metal 4, following sheet metal 5, left sheet metal 6, right sheet metal 7, clip 8, first sheet metal 9, second sheet metal 10, warning circuit 11, shown first sheet metal 9 and second sheet metal 10 all are arranged on the opening of clip 8, clip 8 is clamped on the base 2 has only, first sheet metal 9 and second sheet metal 10 just contact with left sheet metal 6 and right sheet metal 7 respectively, and then can realize warning function.
