Portable intelligent fluid-transfusion or blood-transfusion drop-speed controller

Abstract

The invention relates to a medical portable intelligent infusion or blood transfusion dripping speed controller, which is characterized in that a slot capable of being arranged in an elastic compression pipe of a pump infusion apparatus is arranged on one side of a frame; a synchronous belt pulley is arranged on a motor and connected with an eccentric synchronous belt pulley which is arranged on the frame through a synchronous belt for transmission; one side of the eccentric synchronous belt pulley is provided with an eccentric wheel I which is positioned inside a through opening of a pressure slider; and the pressure slider is arranged inside a guide chute on the frame, and one end of the pressure slider is extended with a convex mandril which is closely connected with the outer pipe wall of the elastic compression pipe of the pump infusion apparatus. The device has small volume, light weight, safe and convenient carrying and use and long working hours, can be used for 10 hours by charging once, can also realize suspension-free and random arrangement of an infusion bottle, sets the dripping speed as required, and achieves the aims of precise infusion and safe monitoring of infusion.

Description

Technical field: [0001] The invention relates to a medical device for controlling the drip rate of infusion or blood transfusion, in particular to a medical portable intelligent infusion or blood transfusion drip rate control machine. Background technique: [0002] Existing medical infusion sets generally adopt the hanging bottle infusion method, and its working state is to hang the (transfusion) liquid bottle high, and use the potential energy of the liquid as the power for infusion, and its infusion performance is related to the height of the liquid bottle position. Cause blood backflow, therefore, inconvenient to use, especially more inconvenient when field rescue is needed or the patient's position is moved. Moreover, in most cases, the infusion rate is manually set by medical staff based on visual inspection and empirical estimation. It is difficult to control the infusion speed and volume stably for a long time, so that medical staff often spend a lot of time repeatedl...

[0002] Existing medical infusion sets generally adopt the hanging bottle infusion method, and its working state is to hang the (transfusion) liquid bottle high, and use the potential energy of the liquid as the power for infusion, and its infusion performance is related to the height of the liquid bottle position. Cause blood backflow, so it is inconvenient to use, especially when field rescue is required or the patient's position is moved

Moreover, in most cases, the infusion rate is manually set by medical staff based on visual inspection and empirical estimation. It is difficult to control the infusion speed and volume stably for a long time, so that medical staff often spend a lot of time repeatedly adjusting the infusion rate. Drop rate

During the infusion process, there must also be a patient's attendant to monitor the dripping status of the liquid medicine or blood in the infusion set at any time, so as not to enter the air when the liquid medicine or blood in the infusion bottle is dripped out, which consumes time and energy. Due to excessive fatigue, it is not found in time that the infusion is completed, causing the patient's blood to flow back or air to enter the downcomer of the infusion set. If the infusion needs to be continued, the air in the catheter needs to be removed again, which will bring trouble to the nurse, increase the pain of the patient or cause Security risks
