Problems solved by technology

Limited to volume and weight, but the portability of existing infusion monitors is poor. When infusion patients go to the toilet, patients get out of bed for inspection, and children cannot follow the fixed position for a long time, the existing infusion monitors cannot leave the original fixed position and go offline use, which is not conducive to the widespread application of infusion monitors in routine patients

Abstract

The invention provides an oxygen output system based on cooperative control of respiratory frequency and target blood oxygen value. The oxygen output system is mainly composed of a control module, a blood oxygen monitoring module, a respiratory frequency sensor, a flow control module, a flow stop valve, a human-computer interaction interface, a communication module and control algorithm. The oxygen output system has the beneficial effects that the flow stop valve responds in real time according to the change of the respiratory frequency, the oxygen output is synchronized with the respiratory action of a patient, compared with the prior art, the oxygen consumption is reduced by about 50%, at the same time, in the oxygen therapy process, the blood oxygen monitoring module monitors whether the blood oxygen value of the patient is stably kept within the target blood oxygen control range or not in real time, the oxygen output flow is dynamically adjusted, and the effectiveness and safety ofthe oxygen therapy are ensured.

Description

technical field [0001] A mobile plug-in module for infusion status monitoring and infusion speed control, which belongs to the plug-and-play component used in conjunction with infusion monitors and belongs to the category of medical equipment. Background technique [0002] Infusion therapy is one of the most commonly used clinical techniques, and it is also a treatment with high clinical risk. In order to realize dynamic monitoring during the infusion process, various infusion monitors have emerged as the times require. Limited to volume and weight, but the portability of existing infusion monitors is poor. When infusion patients go to the toilet, patients leave the bed for inspection, and children cannot follow the fixed position for a long time, the existing infusion monitors cannot leave the original fixed position and go offline Use, be unfavorable for the extensive application of infusion monitor in routine patient. [0003] For this reason, the present invention prop...
