Automatic heating type transfusion system

Abstract

The present invention discloses an automatic heating type transfusion system. The automatic heating type transfusion system comprises an installing seat, a dropper and a transfusion tube; the installing seat is provided with a transfusion system plug and arranged over the dropper; the bottom of the dropper is connected with the transfusion tube; the transfusion system plug is provided with a needle hole; the tail end of the transfusion tube is connected with a needle seat; the transfusion tube is also provided with an adjusting switch; a floating ball, an upper portion of which is spherical shaped, is disposed in the dropper; the circumferential wall at a liquid outlet at the bottom inside the dropper is an inclined plane matched with a lower portion of the floating ball in the dropper; the tail end of the needle seat is provided with a needle bolt and an enclosed interface; the needle seat is also provided with an exhaust needle; the exhaust needle is communicated with an exhaust pipe; the exhaust pipe is equipped with an air filter; and the transfusion tube is provided with a bubble detector. The automatic heating type transfusion system has good safety performance and exhaust and bubble automatic detection reminding functions.

Description

technical field [0001] The invention relates to a medical device, in particular to an automatic heating infusion set. Background technique [0002] At present, the control equipment of intravenous infusion sets used in clinical medicine has a single function, and there are corresponding defects in the equipment with single heating, liquid stop or alarm function. The single heating device does not have the function of stop liquid, causing air embolism in infusion patients However, the lack of heating function of a single liquid stop device will also cause patients to feel uncomfortable in winter, and even convulsions and body numbness symptoms. A single liquid stop device only has a stop liquid function and cannot remind medical staff to treat patients Perform medical care, so there are certain defects in a single infusion control device, [0003] In the process of intravenous infusion, if the air bubbles or the emptying of the liquid medicine are not detected in time due to...

AI Technical Summary

Problems solved by technology

If the amount of air entering is small, it will disperse to the capillaries, combine with hemoglobin, or diffuse to the alveoli, and be excreted with breathing without causing damage to the human body; but when the amount of air entering is large and relatively fast, the air entering Due to the contraction of the heart, it will be impacted by the contraction force of the heart, forming countless small air bubbles, hindering the return of venous blood to the heart and the input to the pulmonary artery, resulting in severe circulatory obstruction. In addition, some gas enters the pulmonary artery, causing pulmonary artery The air embolism in the air, causing the patient to have dyspnea, cough, chest tightness, wheezing and cyanosis and other symptoms, even endangering the patient's life

Therefore, it is very important to detect the air in the infusion tube during the infusion process, and the ordinary infusion set cannot realize real-time detection during the infusion process, so the workload of the medical staff is increased, and it is relatively easy to cause danger. Normal adults can tolerate the critical air input. The volume is about 50ml, which refers to the volume of concentrated infusion of a large section of air embolus, and it will be dangerous for severe patients to infuse more than 10ml
