Description

Portable intelligent transfusion alarm

Technical Field

The utility model relates to a medical treatment monitoring field specifically is a portable intelligent infusion alarm.

Background

The intravenous infusion is a common treatment mode at present, and during infusion, liquid medicine stored in a container flows through an infusion tube, a dropping speed adjusting device and a needle body to enter veins of a human body so as to achieve the purpose of required treatment. In actual life, the problems that the venous blood return of a patient causes secondary injury and the like because family members do not pay attention to or cannot independently realize whether liquid medicine is completely infused exist. The problem is mainly solved by an infusion alarm at present. Currently, the common infusion alarms are classified into the following categories:

the alarm uses a photosensitive sensor as a main part, senses the change of liquid medicine in a transfusion bottle through the change of light, and starts to alarm when the liquid level is lower than the photosensitive sensor, for example, the technology disclosed in the document of Guo Xuan Tao, Wan Cai, Wang Qian, Yan Min, the development of an electronic infusion alarm [ J ]. medical and health equipment, 2015,36(05):23-26. The above-mentioned technique has some deficiencies, and photosensitive sensor is comparatively sensitive to the light change firstly, is not suitable for various positions to put and the great region of light and shade change, and secondly its induction system is difficult to be fixed in on multiple medicine bottle, easily causes the measurement inaccurate.

Infrared ray alarm, which monitors the infusion condition by using infrared ray emitting and receiving devices, processes and judges the monitoring signals, and a buzzer alarms, as disclosed in Chenmiankang, Rojie, Xuliang, a novel venous infusion alarm [ J ] medical and health equipment, 2004(12), 54-55. The technology has some defects, one is that the technology is relatively complex, comprises a large number of circuits, has large occupied volume, high cost and poor reliability and universality, and the other is limited to light-resistant medicines.

The two types of infusion alarms also have a single alarm mode, such as a buzzer or an indicator lamp is used singly for alarming, and for patients or families with hearing or vision disorders, the two types of infusion alarms cannot effectively transmit information to the patients and the families in time.

At present, except large hospitals, a considerable number of patients in small and medium-sized hospitals need infusion treatment every day, when the flow of the patients is large, some hospitals only can stay the patients in an infusion area because of limited places, family members wait outside, or when the patients see the patients and the medical services independently, the condition of independent infusion of the patients can appear, at the moment, most people can choose to see a mobile phone to send out the infusion time, and the situation that the infusion is finished due to the fact that the liquid is not found in time can lead to blood return. Therefore, the importance of alarm monitoring by using a mobile phone and a wireless network is shown.
