Infusion alarm

Abstract

The invention discloses an infusion alarm. The alarm comprises a shell, a circuit board in the shell, a vibration exciter and a paracentetic needle which is arranged on the vibration exciter and protrudes the shell, wherein the vibration exciter is provided with a vibration sensor; a signal of the vibration sensor is inputted into the circuit board; the circuit board is connected with a buzzer; the circuit board controls work of the vibration exciter and the buzzer; when the alarm is used, the paracentetic needle penetrates into a infusion channel, and the vibration exciter vibrates to drive the paracentetic needle to vibrate; when the periphery of the paracentetic needle is changed into air, the vibration frequence, the amplitude and other parameters of the paracentetic needle are changed, and the vibration parameter of the vibration exciter changes due to the influence; the vibration sensor detects the change, generates a signal and sends the signal to the circuit board; the circuit board controls the buzzer to produce sound; and matched use of the infusion alarm with the conventional infusion device can be quickly realized by penetrating the paracentetic needle into an infusion pipeline. The infusion alarm is convenient and quick in operation, and the paracentetic needle can be quickly changed after the infusion alarm is used every time, so infusion alarm can fulfill the requirement of repeated use, has low cost, and contributes to popularization and application.

Description

technical field [0001] The invention relates to a medical device, in particular to an infusion alarm which is quickly used in conjunction with an ordinary infusion set. Background technique [0002] An infusion set is a very common medical device, mainly used to establish a liquid medicine channel between a medical container such as an infusion bottle or an infusion bag and a vein. [0003] When the existing infusion sets are in use, it is necessary to manually observe whether the liquid medicine has been delivered, and to notify the nursing staff in time to perform operations such as changing the dressing and pulling out the needle. Cause gas into the vein, blood backflow and other medical accidents. In order to solve the above-mentioned problems, there have been many infusion alarms, but they are all directly arranged on the infusion set as a part of the infusion set, which greatly increases the manufacturing cost of the infusion set, and because the infusion sets are mo...

Problems solved by technology

[0003] When the existing infusion sets are in use, it is necessary to manually observe whether the liquid medicine has been delivered, and to notify the nursing staff in time to perform operations such as changing the dressing and pulling out the needle. Cause gas into the vein, blood backflow and other medical accidents

In order to solve the above problems, there have been many infusion alarms, but they are all directly arranged on the infusion set as a part of the infusion set, which greatly increases the manufacturing cost of the infusion set, and because the infusion sets are mostly disposable, Therefore, huge waste will be caused, which is not conducive to popularization and application
