Description

An intelligent transfusion monitoring device

technical field

The invention relates to a monitoring device, in particular to an intelligent infusion monitoring device, which belongs to the technical field of medical auxiliary appliances.

Background technique

Infusion set, or infusion pump, as the name suggests, is a medical device for infusion. The traditional infusion method is to hang the liquid in the bottle or the infusion bag at a high place, and use the gravity to make the liquid flow into the vein through the infusion tube. The flow rate is manually adjusted by the clip placed on the tube. The index of adjustment is to see the drop rate (drop/min) in the dropper. Infusion sets are widely used, and during the infusion process, medical personnel or family members are usually required to accompany and observe, and to replace the infusion bottle or pull out the needle to end the infusion in time. Because if the needle is not pulled out in time or the infusion bottle is replaced, after the infusion in the infusion bottle is dripped, blood backflow phenomenon will occur, and severe cases will endanger the life of the patient. For this reason, a device for monitoring the infusion situation of the infusion set is provided. When the infusion in the infusion bottle is ready to drip, it can send an alarm in time, notify/remind the medical staff to replace the infusion bottle or pull out the needle to end the infusion. To improve the safety of infusion, reduce the probability of medical accidents.

In the prior art, there are many devices for monitoring infusion sets on the market. For example, the Chinese utility model patent whose authorized announcement number is CN204275175U discloses an intelligent monitoring device for infusion drip center, which includes a microprocessor module, and respectively A keyboard circuit module connected to the microprocessor module, a miniature pressure sensor module, a liquid crystal display module, an LED light alarm module and a power management module, the keyboard circuit module is used to preset the infusion time, the weight of the infusion bottle and the basic identity information of the patient , the miniature pressure sensor module is used to collect the weight of the infusion bottle in real time, and the microprocessor module calculates the infusion information according to the preset infusion time and the weight of the infusion bottle, and the infusion information includes infusion drop speed, remaining infusion volume, remaining infusion time, The liquid crystal display module is used to display the basic identity information of the patient and/or the infusion information. When the remaining infusion time is less than a certain period of time, the LED light will flash to give an alarm. Although the monitoring device can automatically detect information such as remaining infusion volume and remaining infusion time, so that medical staff can know the patient's infusion situation at any time, the applicant believes that "remaining infusion volume", "remaining infusion time", "infusion drip speed" Such information as the size of the infusion bottle and the liquid for infusion have been determined, and the rate of infusion can be adjusted through the regulator on the infusion set, so the monitoring of these information has no practical significance. And when the patient is unattended during the infusion process and the patient is in a coma, the "alarm when the infusion preparation is completed" and "the position of the patient at this time" are particularly important, especially in hospitals with a large number of people and a large space , in order to rush to the side of the infusion patient at the first time according to the infusion position of the infusion person, and take corresponding remedial measures.

Contents of the invention

In view of the above-mentioned deficiencies, the technical problem to be solved by the present invention is to provide an intelligent infusion monitoring device with a simple structure and strong practicability.

In order to solve the above problems, the present invention is realized through the following technical solutions:

An intelligent infusion monitoring device, comprising a remote monitoring center, a wireless router and N infusion monitoring units, each infusion monitoring unit is connected to the input end of the wireless router, and the output end of the wireless router is connected to the remote monitoring center; each The infusion monitoring unit is used corresponding to an infusion bottle, and is mainly composed of a processor, a power supply for power supply, a display module connected to the output end of the processor, and a voice announcer. The input end of the processor is connected with information Input module and pressure sensor, described pressure sensor is installed on the bottle stopper outside of infusion bottle; A wireless communication module is connected on the SPI bus interface of processor, and described wireless communication module is connected with wireless router, and wherein N is the integer ≥ 3 .

The information input module is used for inputting the name of the infusion patient, the location of the infusion and setting the alarm liquid level of the infusion bottle.

The pressure sensor is used to detect the pressure received at the bottom of the cork of the infusion bottle during the infusion process, and the processor can obtain the The liquid level height value.

In the above solution, the information input module is connected with a location information storage for storing the location information of infusion.

In the above solution, the wireless communication module may be a Zigbee wireless network communication module, and each Zigbee wireless network communication module is connected to a coordinator, and the coordinator is connected to a wireless router.

In the above solution, the information input module may be a matrix button module or a touch screen.
