Detailed Description
The following description is of the preferred embodiments of the invention, and is not intended to limit the scope of the invention.
Examples, see fig. 1 to 4: the automatic liquid changing machine is used for automatically switching a plurality of infusion bottles, wherein one infusion bottle is inserted with an infusion contact pin, and the infusion bottle inserted with the infusion contact pin is used for conveying liquid outwards. The automatic liquid exchanging machine comprises an infusion tray 10, at least two bottle fixing assemblies 20 fixedly arranged on the infusion tray 10, and a liquid exchanging device 30 assembled to the infusion tray 10. Wherein, the bottle fixing assemblies 20 are used for clamping infusion bottles, that is, each bottle fixing assembly 20 can be used for clamping an infusion bottle. The liquid changing device 30 linearly reciprocates to pull out the infusion needle and insert the infusion needle into the corresponding infusion bottle.
The switching process of the infusion bottle is as follows: after the current infusion bottle finishes infusion, the infusion device 30 pulls out the infusion contact pin on the infusion bottle at the preset position. The infusion tray 10 rotates to drive at least two bottle fixing assemblies 20 to rotate by a preset angle so that another infusion bottle is at a preset position. The liquid changing device 30 inserts the infusion needle into the infusion bottle at the preset position. The preset position is the position of the infusion bottle in the infusion state.
The infusion tray 10 drives the bottle fixing assembly 20 to rotate so as to enable infusion bottles clamped on the bottle fixing assembly 20 to be switched conveniently. The liquid changing device 30 clamps the transfusion contact pin to linearly reciprocate, so that the transfusion contact pin is pulled out from the used transfusion bottle and inserted into a new transfusion bottle which is rotationally switched by the transfusion tray 10, thereby realizing automatic switching of the transfusion bottle, and having good automatic switching effect and convenient operation.
As shown in fig. 2 and 3, the liquid changing device 30 needs to pull out and insert the infusion needle, and has a corresponding moving space and a clamping mechanism. In an embodiment, the liquid exchange device 30 includes a moving device 31 and a clamping device 32 fixed on the moving device 31, the clamping device 32 is used for clamping the infusion needle, and the moving device 31 is used for driving the clamping device 32 to reciprocate along a linear direction. The clamping device 32 clamps the infusion needle, and the infusion needle is pulled out or inserted into the infusion bottle in the linear movement process of the moving device 31. The infusion tray 10 rotates to move an empty infusion bottle and to convey another new infusion bottle to a preset position, so that the infusion set 30 inserts an infusion pin into the new infusion bottle, and the switching is convenient. The infusion bottles on the infusion tray 10 are sequentially switched for infusion, so that the labor intensity of medical staff is reduced.
The moving device 31 is used for linear motion to drive the clamping device 32 to move, wherein the moving device 31 can adopt a crank link mechanism, a crank slide mechanism or a screw 3111 nut mechanism to realize linear motion of the clamping device 32. The screw nut mechanism will be described in detail below as an example.
The moving device 31 comprises a mounting frame 312 fixedly arranged on the infusion tray 10, a screw assembly 311 assembled on the mounting frame 312, and a power element 313 driving the screw assembly 311 to move, and the clamping device 32 is arranged on the screw assembly 311. The screw assembly 311 includes a screw 3111, a nut member 3112 slidably disposed on the screw 3111, and a balance wheel 3113 mounted on the nut member 3112, wherein the screw 3111 drives the nut member 3112 to move so that the balance wheel 3113 rolls along the mounting frame 312.
The mounting bracket 312 is similar to a U-shaped structure including two end plates disposed opposite each other. The two ends of the screw 3111 are inserted and mounted on two end plates of the mounting frame 312, the nut member 3112 is slidably disposed between the two end plates, and the power element 313 is fixed to the mounting frame 312 and is in driving connection with the screw 3111. The power element 313 rotates to drive the screw 3111 to rotate, and accordingly, the nut member 3112 and the clamping device 32 mounted to the nut member 3112 move linearly along the axis of the screw. During the movement of the nut 3112, the balance wheel 3113 rolls along the mounting to maintain smooth movement of the nut 3112, with the effect of guiding and eliminating tangential force, and with small movement resistance of the nut 3112.
The clamping device 32 moves linearly with the moving device 31, and can release and clamp the infusion needle by unfolding and folding the clamping component. In an embodiment, the clamping device 32 includes a fixed plate 321 fixedly connected to the moving device 31, a clamping motor 322 fixedly connected to the fixed plate 321, a connecting rod assembly (not shown) pivotally connected to the fixed plate 321, and two clamping blocks 323 slidably disposed on the fixed plate 321 and pivotally connected to the connecting rod assembly, wherein the clamping motor 322 drives the connecting rod assembly to rotate so as to drive the two clamping blocks 323 to fold or unfold.

The clamping motor 322 drives the link mechanism to move around the circle, and the movement range of the link assembly is limited by the movement range of the two clamping blocks 323. By changing the shape of the two clamping blocks 323 in the clamping device 32, the distance between the two clamping blocks is adjusted, and the speed range and the moving range of the clamping device 32 are further adjusted, so that when the infusion needle is clamped, the speed of the two clamping blocks 323 is exactly zero, and the infusion needle is kept in a clamped state.
