First perfusion tube is equipped with peristaltic pump, and the first infrared acquisition for detecting the bubble in the first perfusion tube Device, the upper end of the first perfusion tube are equipped with multiple infusion branch pipes, and the lower end nozzle of each infusion branch pipe is coupled with the first perfusion tube Upper end tube nozzle, it is each infusion branch pipe on be designed with one for control the infusion branch pipe on-off branch pipe switch；

Second perfusion tube is equipped with the second infrared detector for detecting the bubble in the second perfusion tube；

The infusion controller is equipped with multiple control signal output port and multiple transfusion states acquire port；The wriggling The electrical control port of pump and each branch pipe switch is coupled with each control signal output mouth of infusion controller, and described first Infrared detector, the second infrared detector detectable signal output port be coupled with each transfusion state of infusion controller and adopt Collect port.

Further, the Murphy type burette is equipped with the drop speed detection for detecting fluid drop speed in Murphy type burette Device, the detectable signal output port for dripping fast detector are connected to the transfusion state acquisition port of infusion controller.

Further, second perfusion tube is equipped with the pressure detection for detecting the second perfusion tube fluid pressure Device, the detectable signal output port of the pressure detector are connected to the transfusion state acquisition port of infusion controller.

It further, further include warning piece, the electrical control port of the warning piece is connected to the one of infusion controller A control signal output mouth.

The infusion device of automatic replacement fluid infusion provided by the utility model detects infusion process using infrared detector, leads to It crosses the branch pipe switch controlled on each infusion branch pipe to be sequentially opened and closed, the automatic replacement of fluid infusion is able to achieve, to can be reduced nurse's work It measures.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the infusion device of the automatic replacement fluid infusion of the utility model embodiment.

Specific embodiment

The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model Protection scope, the pause mark in the utility model indicates the relationship of sum.

As shown in Figure 1, one kind provided by the utility model embodiment replaces the infusion device of fluid infusion, including infusion automatically Controller (not shown), and the first perfusion tube 1, Murphy type burette 3, the second perfusion tube 2 that are sequentially connected in series from top to bottom, it is described Second perfusion tube 2 is equipped with the drop speed control switch 6 for controlling the second perfusion tube inner fluid speed；

First perfusion tube 1 is equipped with peristaltic pump 5, and the first infrared spy for detecting the bubble in the first perfusion tube Device 91 is surveyed, the upper end of the first perfusion tube 1 is equipped with multiple infusion branch pipes 4, and the lower end nozzle of each infusion branch pipe 4 is coupled with first The upper end tube nozzle of perfusion tube 1, it is each infusion branch pipe 4 on be designed with one for control the infusion branch pipe on-off branch pipe switch 41；

Second perfusion tube 2 is equipped with the second infrared detector 92 for detecting the bubble in the second perfusion tube；

The infusion controller is equipped with multiple control signal output port and multiple transfusion states acquire port；The wriggling The electrical control port of pump 5 and each branch pipe switch 41 is coupled with each control signal output mouth of infusion controller, described First infrared detector 91, the second infrared detector 92 detectable signal output port be coupled with each defeated of infusion controller Liquid status acquires port.

In the utility model embodiment, the Murphy type burette 3 is equipped with for detecting fluid drop speed in Murphy type burette Drop speed detector 8, the transfusion state that the detectable signal output port for dripping fast detector 8 is connected to infusion controller adopts Collect port.

In the utility model embodiment, second perfusion tube 2 is equipped with for detecting the second perfusion tube fluid pressure Pressure detector 7, the transfusion state that the detectable signal output port of the pressure detector 7 is connected to infusion controller adopts Collect port.
