As an alternative to the conventional infusion method, a fluid driving device must first be provided, which can be finely graded to accommodate precise regulation of the flow rate. Patent CN202021923470.2 proposes a disposable infusion set, which, although widely used and cheap in the market, is unsafe for some specific situations, such as going to infusion by oneself alone; sleeping when in transfusion; the health of people can be harmed by the phenomenon of blood return caused by the fact that the transfusion needle tube cannot be pulled out in time due to the reasons of limited number of nurses and the like. Therefore, the disposable infusion set is provided aiming at the problems, and the problems encountered in the infusion process at present are greatly solved. Since the liquid is directly introduced into the patient's vein, which is largely a safety concern for the patient, an alarm system is necessary. When abnormal conditions occur, the infusion should be stopped in time, and light alarm and buzzing alarm are generated to ensure that medical care personnel can handle the abnormal conditions in time. The existing infusion set is more and more automatic and intelligent, and has wider application range besides higher precision and higher safety factor.

The bottle stopper puncture outfit is connected with the liquid communicating vessel under the principle of the communicating vessel, and the liquid communicating vessel means that liquid levels in each vessel directly contacting with the atmosphere always keep the same height when the same liquid does not flow. The purpose of opening the two ends in the liquid communicating vessel is to prevent the interference of pressure on the liquid level, if the liquid in the liquid communicating vessel is regarded as a whole, the liquid will not be static when the pressure is the same at the same depth, and if the pressure is different at the same depth, the liquid will flow to the low pressure place until the balance is reached. In the liquid communicating vessel, the pressure inside the tube is consistent everywhere. The principle of the infusion tube applying the communicating vessel is to prevent the phenomenon of blood return caused by too little liquid in the infusion bottle. When the liquid in the infusion bottle is lower than the needle point of the bottle stopper puncture outfit, an alarm can give an alarm to remind medical personnel to process in time. When the alarm gives an alarm, the machine can automatically stop infusion. The alarm modes generally include red signal lamp flashing and buzzer ringing, namely, light alarm and sound alarm.

As the further improvement of the above scheme, the medicament filter is including the casing with the infusion hose intercommunication, the middle part of casing is provided with the microfiltration membrane and purifies the layer, the microfiltration membrane purifies the layer and is provided with the venthole, install the porous filtration membrane of hydrophobicity in the venthole.
