Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug injection system, and more particularly, to a drug injection system capable of dramatically increasing the stability of a drug injection operation by monitoring and controlling the drug injection state in real time.
Generally, a drug infusion system is a medical device that supplies a medical fluid containing a drug to a vein of a patient.
In the conventional drug infusion system, there is a risk that, when the administration of the drug is terminated, if the injection needle inserted into the vein of the patient is not immediately removed, the blood may flow back through the injection needle or air may be injected into the body to cause embolism.
In addition, since the time required for injecting the drug into the patient through the intravenous injection is relatively long, there has been a problem that the caregiver or the medical staff must frequently check the dose and the administration state of the sap. In addition, in the process of separating the hose connected to the drug infusion system to fill the fluid of the drug infusion system, the medical staff could enter the patient's blood vessel through the hose to cause embolism.

The control device additionally checks the position of occurrence of the density change phenomenon when the blood backflow state and the drug mixing rate error state are simultaneously detected. If the density change phenomenon is detected only in the third hose region, the control device determines that the backflow phenomenon has occurred , And when the density change phenomenon is simultaneously detected in the first hose region and the third hose region, it can be determined that a drug mixing rate error phenomenon has occurred.
Wherein the density sensor comprises: a body implemented in the form of a forceps; A light emitting element and a light receiving element attached to the body so as to face each other at a portion where the hose contacts; And a signal processing unit built in an inner space of the body for calculating and reporting the drug density by comparing and analyzing the amount of light emitted from the light emitting element and the light receiving amount of the light receiving element.
In addition, the system may further comprise a pressurizing device for applying pressure for drug movement to the cylinder, and the control device may further comprise a function of controlling the operation of the pressurizing device based on the drug density sensed through the sensor have.
The system further comprises a plurality of cylinder valves capable of regulating the supply amount of each of a plurality of drugs injected into the cylinder, and controls the opening amount of each of the plurality of cylinder valves based on the drug density sensed through the sensor And the like.
As described above, according to the present invention, when a drug is injected into a patient's blood vessel, air is introduced into the patient's blood vessel, the patient's blood flows backward, and a drug having a mixing ratio is prevented from being injected into the human body, So that stability of the drug injection operation can be dramatically increased.
In addition, the system promptly and visually notifies various error conditions occurring during the drug injection operation so that the medical staff or the caregiver can perform the action more quickly.
In addition, it is possible to provide various information about the drug injection status to an external device such as a hospital server and a medical terminal, so that the external device can perform various additional operations utilizing the information.

For reference, air has an extremely low density value, while the density of blood can have a density value similar to that of a particular drug.
Therefore, the pattern of density change due to air inflow can be easily distinguished from the pattern of density change due to errors of blood reflux or drug mixing rate, but it may be difficult to distinguish density change patterns due to blood reflux and drug mixing rate errors .
