Adjustable constant-pressure infusion device

Abstract

The invention provides an adjustable constant-pressure infusion device. The adjustable constant-pressure infusion device mainly comprises an outer shell, a valve and a knob, wherein a water adding hole is formed in the outer shell, a miniature water pump is mounted at the inner side of the outer shell, a battery is arranged at the right side of the miniature water pump, a sliding switch is mountedat the right side of the battery, the sliding switch is positioned on the outer side of the outer shell, a connecting rod is fixed above the valve, a sealing block is mounted on the outer shell, thesealing block is connected with the outer shell through a spring clip, a through hole is formed in the sealing block, a sealing plug is arranged at the inner side of the through hole, and a waterproofmembrane is arranged at the inner side of the sealing plug. For the adjustable constant-pressure infusion device, the miniature water pump is utilized for pumping water in the outer shell into an inner shell, then pressure is generated for squeezing an infusion bag in the inner shell, further, the infusion of medicines inside the infusion bag is completed, and the problem that the infusion bag needs to be hung at a high position for infusion is solved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an adjustable constant pressure infusion device. Background technique [0002] Intravenous infusion is an effective treatment method commonly used in medical clinical practice to infuse a large amount of sterile solutions or drugs through the vein. It is especially important in the emergency rescue of the wounded in disaster sites or battlefields. Today's infusion generally uses infusion bags, using liquid The physical principle of static pressure depends on the potential energy difference of the liquid's own gravity and enters the vein through the infusion tube. However, in some rescue sites, there are often no good infusion conditions, and medical staff often need to hold the infusion bag with bare hands, which affects the progress of rescue. , increasing the difficulty of rescue. In view of the above problems, an innovative design is carried out on the basis of the original ...
