(3) summary of the invention

The purpose of this utility model is to overcome the defective of existing medical transfusion alarm, provides a kind of structure very simple, and cost is minimum, and is very easy to use, and sensitivity is very high, and is stable and reliable for performance, and saves electric energy, the energy-conservation alarm that use cost is low.

This utility model can also be widely applied to the automatic warning when infuse in other field or gas transmission stops except that can reporting to the police for the transfusion of medical aspect.The scheme that its technical problem that solves this utility model adopts is: set up one up-small and down-big on the fluid pipe conveying fluid

Lower Half be spherical supervision pipe, connect with two binding posts on the alligator clamp activity template respectively with one section double track conductor wire one end, the other end is installed plug, the switch in parallel in plug and the signalling alarm equipment has constituted an electricity consumption loop.When having fluid to pass through in the supervision pipe, the supervision pipe is heaved, and circuit disconnects, and no current passes through in the loop.When fluid stops in the supervision pipe, the fluid pressure complete obiteration, two activity templates of alligator clamp close up, and the metal in two binding posts is connected circuit, and tone generator sends the sound.

This utility model is sensitive high, stable and reliable for performance, does not fail to report, and do not report by mistake, and volume is very little, and simple in structure, cost is low, uses power saving.Use installation also very convenient, can install at any time, also can unload at any time, install and unload and in seconds to finish.

(4) description of drawings

Below in conjunction with accompanying drawing and example this utility model is further specified.

Fig. 1 is this utility model device sketch map

Fig. 2 is the alligator clamp organigram

Fig. 3 is a simple alarming advertiser sketch map

Among the figure: 1 medicinal liquid bottle, 2 supervision pipes, 3 alligator clamps, 4 double track conductor wires, 5 binding posts, 6 binding posts, 7 plugs, 8 pipe conveying fluids, 9 switches, 10 signalling alarm equipments, 11 metal clips, 12 pressure heads, 13 power supplys, 14 tone generators

(5) specific embodiment

In example shown in Figure 1, on common medical pipe conveying fluid (8), set up a upward big water Lower Half down and be the supervision pipe (2) that ball is opened, one activity template of alligator clamp (3) is equipped with binding post (5) and the binding post (6) that is connected with metal clips, one end of double track conductor wire (4) connects with binding post (5), binding post (6) respectively, the other end connects with two metallic rod of plug (7) respectively, and two metallic rod of plug (7) are with contactor (9) association of the artificial signalling alarm equipment of hospital (10).

Using method and principle are: during garter alligator clamp (3) is clipped in the first half of supervision pipe (2), plug (7) is inserted on the wall of ward in parallel with the switch (9) of the artificial signalling alarm equipment of hospital (10).When having medicinal liquid to pass through in the supervision pipe (2), supervision pipe (2) is heaved, and the two activity templates distance of alligator clamp (3) is bigger, and circuit disconnects.When the medicinal liquid in the medicinal liquid bottle (1) has flowed, the hydraulic pressure of the first half disappears earlier in the supervision pipe (2), two activity templates of alligator clamp (3) close up, pressure head (12) compressing metal clips (11) makes it to rotate, when the end of metal clips (11) contacts with binding post (5), circuit turn-on, the artificial signalling alarm equipment of hospital (10) sends the acoustic image signal, reminds and to go before the medical personnel to change dressings or pull out pin for patient.When the first half hydraulic pressure of supervision pipe (2) disappeared, the residual medicinal liquid of Lower Half a period of time medicinal liquid that also can continue to trickle had just all flowed, and is caught unprepared in order to avoid medical personnel change dressings.Therefore, supervision pipe (2) also has the function of time-delay except that the function that supervision is arranged.
