Infusion set

Abstract

The invention provides an infusion device. The infusion device is characterized by comprising a plurality of medicine liquid inlet pipes, a plurality of medicine liquid sensors, a switching and speed regulating component, a control unit and a medicine liquid outlet pipe. The switching and speed regulating component comprises a cylindrical cavity, a cylindrical rotary pipe with a through hole, a locating portion formed by a fixed end locating part and a rotary end locating part, and a driving portion. According to the infusion device, the medicine liquid sensors collect drain-away information of the medicine liquid in real time, and the fixed end locating part and the rotary end locating part of the locating portion collect position information in real time, and the control unit controls the driving portion to operate and drives the cylindrical rotary pipe to rotate according to the drain-away information and the position information, so that the through hole can be communicated with the medicine liquid inlet pipes in sequence, and then a plurality of infusion bottles can be automatically switched for infusion; the control component can also be used for changing the delivery speed of the medicine liquid by controlling a driving motor to operate to drive the cylindrical rotary pipe to rotate and adjust the goodness fit between the through hole and each medicine liquid inlet pipe.

Description

technical field [0001] The invention relates to an infusion device, in particular to an infusion device which is used to automatically switch in sequence on a plurality of infusion bottles and adjust the infusion speed of medicinal liquid. Background technique [0002] Infusion is currently the most commonly used medical method for treating patients in hospitals. During the infusion process, several bottles of liquid medicine need to be continuously delivered according to different diseases, different age groups and different physiques of the patients, and the speed of the infusion is also different. In the traditional infusion method, after infusion of one bottle of liquid medicine, the patient needs to notify the nurse to replace another bottle of liquid medicine, and the infusion speed also needs to be adjusted by the nurse according to the patient's condition. However, due to the negligence of patients or nurses during the long infusion time, it is inevitable that the l...

AI Technical Summary

Problems solved by technology

However, due to the negligence of patients or nurses during the long infusion time, it is inevitable that the medicinal solution in the infusion bottle has been transfused and the other bottle of medicinal solution has not been changed, and even the phenomenon of blood backflow occurs; The treatment effect of the patient's condition also has a great influence, but the nurse can only rely on visual inspection when adjusting the infusion speed, and there is no scientific and accurate display data as a basis to adjust the infusion speed

In this way, it is not only easy to cause harm to patients, but also increases the workload of medical staff.

[0003] Therefore, the prior art lacks an infusion device that can automatically switch the infusion on multiple infusion bottles and can adjust the infusion speed of the medicinal solution.
