Micro automatic constant pressure infusion set

Abstract

The invention relates to the technical field of medical equipment, in particular to a miniature automatic constant pressure infusion set. The infusion set is composed of two arc-shaped splints arranged opposite to each other and the infusion bag held there, a stepping motor, a pressure sensor and a rechargeable battery; Gears, reel gears and tension steel wires work together to provide a certain clamping force to the arc-shaped splint, so that the arc-shaped splint squeezes the infusion bag with a constant pressure, and the pressure information of the infusion tube is sensed by the pressure sensor, and processed by the microcomputer Finally, the action of the mechanical part is regulated; the miniature automatic constant pressure infusion device of the present invention is small in size and easy to use, and can automatically maintain a constant infusion pressure during the infusion process. It is suitable for all kinds of clinical intravenous infusion, especially suitable for the use of emergency field rescue.

Description

technical field [0001] The invention belongs to the field of medical life sciences, relates to medical equipment, in particular to a miniature automatic constant pressure infusion device. Background technique [0002] Intravenous infusion is commonly used in medical clinical practice, and is an effective means of treatment for transvenously infusing a large amount of sterile solution or medicine. It is especially important in the emergency rescue of the wounded in disaster sites or battlefields. The commonly used infusion method at present is: the infusion bag or bottle is suspended on a high place, utilizes the physical principle of hydrostatic pressure to rely on the self-gravity potential energy difference of the liquid to naturally enter the vein through the infusion tube. However, in some rescue sites, there are often no good infusion conditions, and medical staff are often required to hold the liquid bag with bare hands to guard, which affects the progress of rescue an...

AI Technical Summary

Problems solved by technology

However, in some rescue sites, there are often no good infusion conditions, and medical staff are often required to guard with fluid bags with bare hands, which affects the progress of rescue and increases the difficulty of rescue.

[0003] At present, the commonly used intravenous infusion treatment in clinical practice is to use a syringe type automatic infusion device for treatment. This infusion device is characterized by accurate infusion volume, but its obvious defects are: the infusion volume is small (usually less than 100ml), and The size of the device is large, especially not suitable for the use of emergency ambulance
