Infusion device and use method thereof

Abstract

The invention discloses an infusion device. The infusion device comprises a plurality of medicine bottles, a main infusion tube, transfer infusion tubes, an exhaust tube, a force measuring device, a controller and an alarm, wherein the main infusion tube is in liquid communication with the first medicine bottle of the multiple medicine bottles; the transfer infusion tubes are in liquid communication with adjacent medicine bottles of the multiple medicine bottles; the exhaust tube is in air communication with the tail medicine bottle of the multiple medicine bottles and the external atmosphere;the force measuring device is used for measuring the gravity of the first medicine bottle; the controller controls the alarm to give an alarm based on the condition that the gravity difference of thefirst medicine bottle measured by the force measuring device within a predetermined time period is less than a preset threshold. The infusion device has the advantages that the detection precision isimproved, the production cost is reduced, the alarm can give an alarm after medicine liquid in the medicine bottles drips off to prompt a medical worker to replace the medicine bottles in time to prevent the patient from having blood returning.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an infusion device and a usage method. Background technique [0002] In modern medical methods, infusion therapy is widely used in major medical institutions. When a patient needs to infuse a large amount of medicine, the medical staff will prepare multiple bottles of medicine and infuse them in the order ordered by the doctor. During the infusion process of the patient It is necessary for the medical staff to replace the medicine in a timely manner. After the medicine is dripped, if the medical staff does not replace the empty medicine bottle in time, it may cause blood backflow to the patient and bring immeasurable safety hazards to the patient. [0003] In order to prevent patients from the problem of blood backflow, infrared detection technology is mainly used in the prior art to detect whether there is liquid medicine dripping in the dripping funnel connected to the...

[0002] In modern medical methods, infusion therapy is widely used in major medical institutions. When a patient needs to infuse a large amount of medicine, the medical staff will prepare multiple bottles of medicine and infuse them in the order ordered by the doctor. During the infusion process of the patient It is necessary for the medical staff to replace the medicine in time. When the medicine liquid is dripped, if the medical staff does not replace the empty medicine bottle in time, it may cause the patient's blood backflow problem and bring immeasurable safety hazards to the patient.

[0003] In order to prevent patients from the problem of blood backflow, infrared detection technology is mainly used in the prior art to detect whether there is liquid medicine dripping in the dripping funnel connected to the medicine bottle and then give an alarm to remind the medical staff to replace the empty medicine bottle in time, but it is necessary to Additional jigs are made to fix firmware such as the dripping hopper and sensors, and the dripping hopper cannot be shaken at will, otherwise it will affect the detection. Therefore, the accuracy is poor and more costs will be increased
