Problems solved by technology

[0010] But the existing hanging bottle infusion system all has the defective that is difficult to overcome:
Although this method is applicable to all hanging bottles, it is not suitable for all medicines. Many medicines added to the hanging bottles during infusion in the hospital are not colorless and transparent, but colored like brown or orange. Medicines, especially blood transfusions, the blood is dark red and more viscous than general colorless and transparent liquids. These different liquids have great differences in the absorption of infrared rays
so this method is not suitable for all cases

Embodiment 1

[0029] Such as figure 1 , the infrared light emitter A used as the monitoring module is the incident light source, the incident light is incident from the upper part of the air bag of the Murphy dropper, if there is liquid in the air bag, the light enters the liquid surface obliquely from the edge of the liquid surface in the air bag, and the light refracts in the direction Changed, unable to focus on the infrared light receiver B outside the Murphy's pipette. If there is no liquid in the airbag, the light will focus on the infrared light receiver B outside the Murphy dropper after passing through the airbag. At this time, the monitoring module will send an alarm signal to the main control circuit, which will control the alarm module to alarm. The side sends a wireless alarm signal, so that the monitoring room can see the infusion alarm corresponding to the bed number, and take timely measures.

[0030] Adjust the above-mentioned infrared light emitter A, the incident light c...

Embodiment 2

[0032] Such as figure 2 , image 3 , the infrared light emitter A used as the monitoring module is the incident light source, and the incident light enters from the side of the infusion tube or the air bag. Since the tube is circular, as long as the incident light does not pass through the center of the tube, the light entering the tube Just because the pipeline is full of liquid, refraction occurs, and the direction changes. If the infrared light receiver B is placed on the other side of the pipeline, the light in the direction of the incident light cannot be monitored.

[0033] If there is no liquid in the bladder, the light can be detected. At this time, the monitoring module sends an alarm signal to the main control circuit, and the main control circuit controls the alarm module to alarm. If there is a wireless monitoring side to send a wireless alarm signal, the monitoring room can see the infusion alarm corresponding to the bed number, and take timely measures.

Abstract

The invention discloses a monitoring method of a suspension bottle transfusion system. According to the method, the direction of ray is changed through refraction or total reflection of the ray between air and liquid, so that whether liquid exists in a transfusion pipeline is detected. The method has the advantages that the original light intensity judgment is changed into light signal judgment, the structure of detection equipment is simplified, the reliability is higher, the equipment is more convenient to mount and use, the applicability of infusion fluid constituents is higher, and a good solution is brought to the automatic monitoring and alarming during transfusion.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a monitoring method for a hanging bottle infusion system. Background technique [0002] In general hospitals, when the patient uses the infusion bottle, there is usually someone waiting by the side or the ward has a call system, especially when the infusion is for a coma or unconscious patient, the patient must have family, friends or It's a nurse waiting. However, in the middle of the night, the caregiver may doze off due to fatigue, and if the needle is not pulled out in time after the fluid is transfused, it may cause blood backflow and seriously endanger the patient's body. Therefore just need a device that automatically monitors whether the transfusion is finished. [0003] At present, there are mainly three methods to realize infusion monitoring: [0004] 1. Depending on the change in the weight of the bottle. This method judges whether the infusion is complet...
