Embodiment

Show among the figure that the utility model is a capsule that plastic or other material is made, be divided into box body 1, lid 2 two parts.In the box body 1 music sounding circuit is housed, comprises power switch 5, battery 6, musical film 7, loudspeaker 8 etc.A gravity spring switch 4 also is housed in the box body 1, it is made up of pull bar 9, lower draw-bar 10, spring 11, spring 11 is fixed on the box bottom, the last support 15 of pull bar 9 is placed on the upper surface of spring 11, the body of rod passes the tie rod hole 16 that spring 11 longitudinal axis pass at the bottom of the box again and arrives outside the box bottoms, and lower draw-bar 10 hangs over the bottom of the body of rod.An electrode contact blade is installed on the upper surface of support 15 on the pull bar 9, be called contact 12 down, simultaneously an electrode contact blade has been installed at the medial surface of lid, be called contact 13, last contact 13 is corresponding with the center of following contact 12, last contact 13, following contact 12 are connected between the musical film 7 and battery 6 of music sounding circuit, circuit turn-on when they contact, and circuit disconnects during separation.Also have on one on the top of lid 2 and to link up with 3.Box body 1 is that buckle-type is connected with lid 2, and 2-4 connecting link 17 arranged on inboard wall of cartridge, on the connecting link 17 screw is arranged, and bolt penetration hole 18 is arranged on the lid 2, and the position of bolt penetration hole 18 is corresponding with the position of connecting link 17 with quantity.During installation, the screw that bolt 19 is passed bolt penetration hole 18 and connecting link 17 screws, and box body 1 is connected closely with lid 2.

The utility model will be gone up hook 3 and hang on the Infusion support in use, and the infusion bottle that will fill with liquid again hangs on the lower draw-bar of the present utility model.It is drop-down with pull bar 9 that the weight of liquid overcomes the elastic force of spring 11, and upper and lower contact is disengaged, and music sounding circuit disconnects, and loudspeaker 8 is sounding not.After the transfusion beginning, liquid reduces gradually, when liquid reduces to the weight of prior adjusting, the elastic force of spring 11 contacts upper and lower contact top on the last support 15 of pull bar 9, and music sounding circuit is connected, loudspeaker 8 can send musical sound, reminds the relevant personnel.

In the utility model, in order to make upper and lower contact contact firmly, a miniature magnet 14 has been installed between last contact 13 and lid medial surface, and support 15 usefulness ferrous materials will be installed down on the pull bar of contact 12 makes, perhaps on last support 15, assembled iron surface.Also miniature magnet 14 can be installed on the pull bar on the support 15, and the suction disc of ferrous material is installed at last contact 13 back sides.

The utility model in use, in order to regulate the distance of upper and lower contact, it is good that they can both be contacted when using the infusion bottle of Different Weight in good time, also on its lid, adjusting knob is housed, the top of adjusting knob is index dial 20, the bottom is a rotation axis 21, there is axle sleeve 22 outside of rotation axis 21, threads engaged is arranged between them, there is 3-4 vertically axle sleeve projection 23 in axle sleeve 22 outsides, have and the corresponding vertical chute 24 in axle sleeve projection 23 positions in lid 2 inboards, axle sleeve projection 23 is stuck in the chute 24.During application, turning knob, rotation axis 21 rotates, because the axle sleeve 22 of threaded engagement is subjected to the restriction of 24 pairs of axle sleeve projectioies 23 of chute with it, axle sleeve 22 can not rotate, and can only be moved up and down along chute 24 by the thread belt moving axis cover 22 of rotation axis 21.At this moment, therefore last contact 13 is installed in the bottom of axle sleeve 22, and going up contact 13 just can the up-down adjustment position, and this work should be tested and be adjusted in advance by the medical personnel of this reminiscences of use, according to the infusion bottle rotation adjusting knob of Different Weight, rotation numerical can be seen index dial 20.

Spring 11 of the present utility model adopts the tower spring, and the diameter of top spring coil is 1/2-1/3 with the diameter ratio of bottom spring coil, and this springback is strong, axial stability good, can reduce resistance.
