Embodiment 1

[0011] An embodiment of the present invention provides an alarm device for an intravenous infusion set. The device includes a light emitting module, a light receiving module, a control module, and an alarm module. The light emitting module is used to send out a light signal, which is transmitted to the light receiving module after passing through the intravenous infusion set The optical receiving module is used to receive the optical signal from the optical transmitting module, and generates a pulse signal according to the optical signal; the relevant information of the control module recording the pulse signal meets the first condition or the second condition, and the control module transmits the alarm signal to the alarm module, wherein The relevant information of the pulse signal includes the time interval of the pulse signal and the number of times the pulse signal is generated. The first condition is that the time interval of the pulse signal is greater than or equal to the...

Embodiment 2

[0015] The embodiment of the invention also provides an automatic control device for the speed of the intravenous infusion set, which includes the alarm device for the intravenous infusion set in Embodiment 1. The automatic control device also includes a speed control module, the control module records the time interval of the pulse signal, the time interval of the pulse signal The relationship between the interval and the preset second preset time interval generates a speed modulation signal, and transmits the speed modulation signal to the speed control module; the speed control module regulates the speed of the intravenous infusion set according to the speed modulation signal.

[0016] In one example, generating the speed modulation signal according to the relationship between the time interval of the pulse signal and the preset second preset time interval includes: generating an increase in response to the time interval of the pulse signal being greater than the preset secon...

Embodiment 3

[0019] Utilizing the principle of refraction of liquid, when there is liquid, the photosensitive resistor is directly irradiated by light, and the resistance value is small, while when there is no liquid, the photosensitive resistor is not exposed to light, and the resistance value is relatively large. The alarm circuit is controlled by the circuit control part to issue an alarm.

[0020] The intravenous infusion set alarm device includes: a light emitting module, a light receiving module, a control module, an alarm module,

[0021] In one example, the light emitting module is a light bulb, and the light receiving module is a photoresistor.

[0022] In one example, the control circuit is used to control the alarm circuit to issue an alarm.

[0023] In one example, the alarm circuit is used to sound the alarm and light the LED.

[0024] In one example, when the patient is infused with fluid, the light emitted by the light source LED is received by the photodiode and converted...

Abstract

The invention relates to an intravenous infusion device alarm device. The device comprises a light emitting module, a light receiving module, a control module and an alarm module, and the light emitting module is used for emitting an optical signal which is transmitted to the light receiving module after the signal passes through an intravenous infusion device; the light receiving module is used for receiving the optical signal from the light emitting module, and generating a pulse signal according to the optical signal; the control module records the relevant information of the pulse signal to satisfy a first condition or a second condition, and the control module transmits an alarm signal to the alarm module; the alarm module sends an alarm message according to the alarm signal. The intravenous infusion device alarm device has simple structure and principle, high precision, low cost and convenient loading and unloading, belongs to non-contact measurement, and does not contaminate drugs.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an alarm device for an intravenous infusion set. Background technique [0002] With the development of society, people in the 21st century pay more and more attention to safety issues, especially medical and medical safety issues. At present, hospitals usually use dedicated nurses to monitor patients' infusions, or patients' family members special monitoring. In this case, once the manual on-duty monitoring is not in place, the bottled infusion may cause gas to enter the human body through the infusion line after the liquid is infused, which is usually called a gas embolism, which will cause serious physical injury to the patient and even cause death. Contents of the invention [0003] The purpose of the present application is to solve the problem that urine wetness cannot be found in time in the prior art. [0004] In order to implement the above purpose, the present invention prov...
