Abstract
The utility model discloses an injection pump with a protection lock, which comprises a pump head and a liquid bag, wherein the pump head or the shell of the liquid bag is provided with a protection lock device for controlling the injection pump to operate normally after the liquid bag is clamped in place. The injection pump disclosed by the utility model has a reasonable structure and can be ensured to operate only after the liquid bag is clamped in place.
Description
Technical field
This utility model relates to a kind of killer injecting pump.
Background technology
The trace killer injecting pump generally is made up of two parts, is easy to generate the situation of clamping endure not in place in killer injecting pump and the packed clip process of liquid, and this will produce very big risk, as serious problems such as excessive infusions.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can guarantee that liquid is packed to clip to the killer injecting pump that has protection lock that a back killer injecting pump could move work.
Technical solution of the present utility model is:
A kind of killer injecting pump that has protection lock comprises pump head and liquid bag, it is characterized in that: be equipped with on the pump head or on the liquid bag shell control killer injecting pump liquid is packed could normal operation after clipping to the position the protection lock device.
Described protection lock device comprises the shift fork of stirring the killer injecting pump run switch, and dress drives the protection button of shift fork on the shift fork, and the shift fork nearside is provided with the spring that the protection button is lifted, and it is prominent that liquid bag end is provided with the card that spring is pressed down, and card is prominent to be cooperated with the clamping of protection button.
The protection button is rotary type, direct-push or button.
Spring is to pull spring, torsion spring or common spring.
Switch is switch with mechanical contact, Hall switch, photoelectrical coupler or inductive switch.
This utility model is rational in infrastructure, can guarantee that the packed back killer injecting pump that clips to of liquid could operation work.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the general assembly drawing of Fig. 1 embodiment.
The specific embodiment
A kind of killer injecting pump that has protection lock comprises the pump housing 6, liquid bag 5, be equipped with on the pump head or on the liquid bag shell control Teat pipette liquid is packed could normal operation after clipping to the position the protection lock device.
Described protection lock device comprises the shift fork 5 of stirring pump operation switch 4, and dress drives the protection button 1 of shift fork on the shift fork, and the shift fork nearside is provided with the spring 2 that the protection button is lifted, and liquid bag end is provided with the card that spring is pressed down and dashes forward 7, and card is prominent to be cooperated with the clamping of protection button.
The protection button is rotary type, direct-push or button.Spring is to pull spring, torsion spring or common spring.Switch is switch with mechanical contact, Hall switch, photoelectrical coupler or inductive switch.
Killer injecting pump is not packed liquid bag or be unkitted into when clipping to, and spring 2 does not have oppressed, and an end of spring (as A among the figure) lifts, and protection button 1 can't put in place, makes that shift fork 3 can't toggle switch, and killer injecting pump can not be moved.After liquid bag 5 and killer injecting pump clamping put in place, the liquid bag was depressed the spring of lock, and the A end of spring also moves down thereupon, and protection button 1 is promptly removable, and the liquid bag is stuck.This moment, shift fork toggle switch 4 closures provided signal, and killer injecting pump can move, thereby reaches the purpose of protection.
Claims (5)
