Abstract
The utility model discloses a transfusion inductor, which comprises a shell and a lock claw, wherein the lock claw is connected with the shell through a torsion spring, and the lock claw and the torsion spring are both arranged outside the shell. As the lock claw and the torsion spring are arranged outside, liquid medicine can be instantly cleaned up after emerging on the torsion spring, thereby avoiding the phenomenon of torsion spring failure, and increasing the service life of the transfusion inductor.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of drop induction apparatus that is used for intravenous injection drip infusion pump.
Background technology
The drop induction apparatus is parts of intravenous injection drip infusion pump, and it also will be held the Mo Feishi pipe tightly and prevent that it from dropping except gathering the drop signal.The hold-fast body of existing drop induction apparatus is to constitute (see figure 2) by shell, installation stage clip in the enclosure with the holding claw that is connected stage clip, holding claw is stretched out shell and is held Mo Feishi pipe tightly under the normality, as long as when the Mo Feishi pipe need unclamp, press with stage clip and hold the button that is connected in addition, just holding claw is shunk back in shell.This drop induction apparatus in use medicinal liquid is easy to enter in the shell and then deposit to crystallization on the stage clip from the holding claw loose slot of shell, causes stage clip to lose efficacy, and the drop induction apparatus can't be worked.The contact surface of drop induction apparatus and Mo Feishi pipe is an arc surface in addition, make easily and the Mo Feishi pipe between easily produce relative motion, reduce the safety of intelligent peristaltic pump.
The utility model content
The purpose of this utility model is to provide the drop induction apparatus of a kind of long service life and safety.
This drop induction apparatus that this utility model provides comprises shell, holding claw, and described holding claw is connected with shell by a torsion spring, and holding claw and torsion spring are all in the outside of shell.
The one side that described holding claw is adjacent with the Mo Feishi pipe has the radius of the arc radius of a plurality of positions less than the Mo Feishi pipe.
Because this utility model is arranged on the outside with holding claw and torsion spring, after occurring the medicinal liquid crystallization on the torsion spring, can in time see and clean out at once, the torsion spring failure phenomenon can not appear therefore, increased the life-span of drop induction apparatus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the prior art constructions sketch map.
The specific embodiment
As can be seen from Figure 1, this utility model comprises shell 1 and holding claw 2, holding claw 2 is connected with shell 1 by a torsion spring 3, and holding claw 2, torsion spring 3 and connecting pin 4 all are exposed, and just can in time see and clean out after the medicinal liquid crystallization occurring, therefore torsion spring 3 failure phenomenon can not appear, increased the life-span of drop induction apparatus, holding claw 2 is provided with a plurality of protruding buttons 21 with the one side that the Mo Feishi pipe contacts in addition, so that locking Mo Feishi pipe, prevent that it from moving, improve the safety of transfusion thus.When this utility model uses, clutch the torsion spring end of holding claw 2, holding claw 2 front ends are opened, insert the Mo Feishi pipe, loose one's grip then, it is fixed between holding claw 2 and the shell 1, just can normally use.
Claims (2)
1, a kind of drop induction apparatus comprises shell (1), holding claw (2), it is characterized in that holding claw (2) is connected with shell (1) by a torsion spring (3), and holding claw (2) and torsion spring (3) are all in the outside of shell (1).
2, drop induction apparatus according to claim 1 is characterized in that holding claw (2) and Mo Feishi pipe contact surface have a plurality of protruding buttons (21) that are used for locking Mo Feishi pipe.
