Description

A Portable Infusion Monitoring and Reminder Device Based on Electronic Scale

technical field

The utility model belongs to the technical field of medical equipment auxiliary equipment, in particular to a portable transfusion monitoring and reminding device based on an electronic scale.

Background technique

Infusion is one of the basic medical methods for treating diseases at present. Hospital infusion requires escorts or patients to check the liquid level of the medicinal solution from time to time. If the infusion is over and is not found in time, it will cause harm to the patient's body. In addition, the infusion speed is adjusted and set by the nurse at the beginning of the infusion, but during the infusion process, due to various reasons such as sleeping and turning over of the patient, accidents such as inadvertently interrupting or increasing the flow may occur. Due to manual inspection, it is impossible to judge whether the flow rate of the liquid medicine is normal, and the infusion speed is too high or too slow, which will have adverse effects on the patient, and even threaten the life of the patient, causing casualties. Therefore, there is an urgent need for a transfusion monitoring and reminding device, which can not only remind the transfusion to be over before the transfusion ends, but also send an alarm when the transfusion speed is abnormal, and notify the medical staff to come to deal with it in time.

Existing many transfusion monitoring and alarming devices in the prior art, but the technology used is relatively old, needs to form a system to use, and can't be carried, can't be used for individual, can't be applicable to vast village or community hospital. There is also a simple infusion alarm on the market now, which uses the capacitance principle to detect whether there is liquid in the infusion tube, thereby prompting whether the infusion is over. Yet above-mentioned two kinds of infusion alarm devices all have defects: the one, do not set the alarm threshold in advance, only can send reminder when there is no medicine liquid completely in the infusion container; The two, cannot monitor infusion speed.

In view of the above-mentioned prior art, it is necessary to improve the structure of the existing transfusion monitoring and reminding device. For this reason, the applicant has made a beneficial design, and the technical solution to be introduced below is produced under this background.

Contents of the invention

The purpose of this utility model is to provide a portable infusion monitoring and reminding device based on electronic scales, which can display the infusion speed during the infusion process, and send an alarm when the remaining amount of medicinal liquid reaches a preset threshold or the infusion speed is abnormal.

The purpose of this utility model is achieved in this way, a kind of portable transfusion monitoring reminding device based on electronic scale, it is characterized in that: comprise single-chip microcomputer, liquid crystal display screen, buzzer, button, weighing sensor and analog/digital (A/ D) A conversion module, the single-chip microcomputer is respectively connected with the liquid crystal display, the buzzer, the key and the analog/digital conversion module, and the analog/digital conversion module is connected with the load cell.

In a specific embodiment of the present utility model, the load cell is equipped with a hook for hanging the infusion container.

In another specific embodiment of the present utility model, the infusion monitoring and reminding device further includes a wireless module, and the wireless module is connected to the single-chip microcomputer.

In yet another specific embodiment of the present utility model, the wireless module is a Bluetooth or WIFI wireless module, and the wireless module communicates wirelessly with the mobile phone.

In yet another specific embodiment of the present utility model, the infusion monitoring and reminding device further includes a light emitting diode, and the light emitting diode is connected to the single chip microcomputer.

Because the utility model adopts the above structure, compared with the prior art, the utility model has the beneficial effects of: the real-time monitoring of the remaining amount of the liquid medicine can be carried out on the infusion containers of different specifications, the infusion speed can be preset, and real-time monitoring is performed during the infusion process. Display the remaining amount of liquid medicine and the infusion speed. When the remaining amount of liquid medicine reaches the preset threshold or the infusion speed is abnormal, the light-emitting diode and the buzzer will send out sound and light alarms; the wireless module is connected to the mobile phone, and the alarm parameters can be set on the mobile phone. Real-time monitoring of the remaining amount of liquid medicine and infusion speed can be realized through the mobile phone, and corresponding alarm reminders can be realized; it can also be used as an electronic scale to realize the weighing function; it is small in size, easy to carry around, and has a wide range of applications.
