Automatic electronic infusion alarm

Abstract

The invention provides an automatic electronic infusion alarm which comprises a shell, a sensing module, a control module, an alarm range adjusting module, an alarm display sound module and a direct current power module. According to the alarm, a pressure signal is converted into a weak electric signal, so that pressure change of an infusion bottle is acquired, and the defects of other induction modes are fundamentally overcome; the adopted pressure sensor is simple in principle, the influence caused by physical interference factors such as external sound, light, electricity and magnetism is small, and the error is small; circuits of the control module are integrated to a PCB, and convenient for split charging; the alarm quality is adjustable by voltage dividing through a resistor, and the alarm has the advantages that corresponding threshold values can be set aiming at different infusion bottle specifications, and the design is humanized; the principle of the whole device is easy to understand, and the device is convenient to assemble, use and maintain by medical care personnel; and moreover, the cost is low, the medical demands on the general population can be greatly met, and the device disclosed by the invention is small in size, low in power consumption and convenient to fix and use in the hospital and can be widely applied to various large and small hospitals and large and small clinics.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a novel electronic automatic infusion alarm. Background technique [0002] When the patient is transfused in the hospital, he generally needs the care of a nurse or family member. However, the time for infusion is relatively long and there are many things in the hospital, so it is inevitable that there will be some shortage of manpower. If no one is watching, it will cause great mental pressure to the patient during the infusion, making it impossible to have a good rest during the infusion. Although failure to pull out the infusion needle in time will not bring life danger, there will be venous blood return phenomenon, which will bring a lot of shock to those patients who do not have basic medical knowledge, and affect the normal work of the hospital. With the automatic infusion alarm, when the droplet is reduced to a certain amount, an alarm can be issued in time to remind the...

Problems solved by technology

The production and installation of the first type are quite inconvenient and unhygienic. The detection method of the second type is too fine, so that the installation is not enough, which will lead to the consequences of not being able to alarm correctly.

And its equipment has the disadvantages of being difficult to install and the sensor is easy to fall off, and the cost of photoelectric sensors that can be applied to infusion alarms is generally relatively expensive, and has high requirements for the environmental conditions of the measurement, and is easily affected by the outside world and cause false alarms. necessary hazard

[0005] For infusion monitors based on the principle of weighing, most of the existing equipment uses springs to control the quality of the alarm by changing the elongation of the spring through the change of the mass. This method is affected by the change of the elastic limit of the spring, which is not conducive to long-term monitoring. Generally speaking, there is a lack of a relatively cheap and easy-to-install infusion alarm device

[0006] For the infusion monitor based on the principle of drip counting, the number of drops per milliliter of liquid medicine is related to the osmotic pressure of the liquid medicine, and the type of scalp needle also affects the number of drops per milliliter. It is too fine and has few applications. At present, there is no perfect application. The principle of infusion alarm
