Automatic control transfusion device and automatic control method thereof

Abstract

The invention relates to the technical field of medical equipment, and in particular relates to an automatic control transfusion device and an automatic control method thereof. The automatic control transfusion device comprises a transfusion system and an automatic control system, wherein the transfusion system comprises a hanging support, transfusion bags and a transfusion apparatus; and the automatic control system comprises a force sensor, an on-off control device and a control unit. The method comprises the following steps of: detecting weights of the transfusion bags, calculating the liquid remaining quantity according to the weights of the transfusion bags, cutting off a transfusion pipeline and giving an alarm when the liquid remaining quantity is less than a threshold value. The automatic control transfusion device and the automatic control method thereof, disclosed by the invention, have the advantages that: the alarm can be given early and the transfusion pipeline can be automatically cut off when the liquid is going to drip off; the automatic switchover between the transfusion bags can be controlled; manual operation of medical workers is not needed; and the alarm adopts a plurality of types such as sound, light and the like, different alarm sounds and lights can be set according to different situations, the reliability is strong and the transfusion safety can be fully guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic control transfusion device and an automatic control method thereof. Background technique [0002] The usual infusion device is mainly composed of an infusion bag and an infusion set. The infusion set is controlled on and off by a manually controlled rolling wheel device. During the infusion process, medical personnel are required to monitor, especially when the infused solution is about to be finished. Remove the infusion set in time and take care of the needle hole of the patient. If the infusion set is not removed in time due to negligence, it will cause blood return and endanger the life safety of the patient.

Problems solved by technology

[0002] The usual infusion device is mainly composed of an infusion bag and an infusion set. The infusion set is controlled on and off by a manually controlled rolling wheel device. During the infusion process, medical personnel are required to monitor, especially when the infused solution is about to be finished. Remove the infusion set in time and take care of the needle hole of the patient. If the infusion set is not removed in time due to negligence, it will cause blood return and endanger the life safety of the patient. For patients who need to infuse multiple bags of liquid at the same time, the first Dispensing a second bag of liquid when the bag of liquid is infused often leads to complications such as blood return, coagulation and blockage of the patient while waiting for the liquid to be dispensed, which is also a hidden danger of medical disputes

[0003] In the prior art, there are also those that can automatically cut off the infusion pipeline or give an alarm when the transfused solution is about to be transfused, such as an infusion set disclosed in patent application 200810014517.0 and an infusion alarm disclosed in patent application 200910062959.7. Their shortcomings Yes: they all adopt a contact structure, which is easy to cause pollution to the transfused solution, and the direct contact of external objects with the transfused solution makes most patients unacceptable, and the infusion set disclosed in the patent application 200810014517. Under the effect of buoyancy and liquid buoyancy, the liquid outlet at the bottom of the drip pot is closed with the drop of the liquid level to cut off the infusion pipeline, which has low reliability and is not easy to process and produce; and the infusion alarm disclosed in the patent application 200910062959.7 can only be used when the infused liquid When the infusion is about to be completed, an alarm will be issued, and the infusion line cannot be cut off automatically. The medical staff need to manually remove the infusion set. If there is negligence, it will still endanger the patient's life.
