Problems solved by technology

[0006] The technical problem to be solved by the present invention: in the initial period of time in the existing infusion set, the liquid medicine tends to drip very quickly, which cannot be dripped at a uniform speed and is easy to bring discomfort to the patient's body; and when the infusion speed is fast, due to The air intake pipe cannot replenish the gas to the infusion bottle in time, and it is prone to the phenomenon that the liquid medicine cannot be dripped at a uniform speed and stability

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The infusion set is a common disposable medical consumable that is used for intravenous infusion after aseptic treatment to establish a channel between the vein and the liquid medicine. Generally, it is composed of venous needle, protective cap, infusion hose, liquid medicine filter, flow rate regulator, drip funnel, cork puncturer, air inlet pipe, and air filter connection. The air filter is set in the air inlet pipe; about the infusion set The knowledge belongs to the existing common knowledge and will not be described in detail.

[0023] A medical infusion device and a manufacturing method thereof, comprising a first cylindrical container, a second cylindrical container, a liquid medicine inlet, an air inlet, and an infusion port; the first cylindrical container is located inside the second cylindrical container, and the first The cylindrical container and...

Abstract

The invention discloses a medical liquid infusion device which comprises a first cylindrical container, a second cylindrical container, a medical liquid adding port, an air inlet port and a liquid infusion port. The first cylindrical container is located in the second cylindrical container, the first cylindrical container and the second cylindrical container share an upper bottom surface and share a lower bottom surface, and the side face of the first cylindrical container is not connected with the lower bottom surface, so that the first cylindrical container and the second cylindrical container are completely communicated. The medical liquid infusion device is matched with an existing liquid infusion apparatus for usage and can make the medical liquid flowing speed in the whole liquid infusion process very stable.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical transfusion device. Background technique [0002] The medical infusion bottle is a bottle of liquid that is used for infusion in the human body when the patient is infused. The infusion set is a common disposable medical consumable that is used for intravenous infusion after aseptic treatment to establish a channel between the vein and the liquid medicine. Generally, it is composed of a venous needle, a protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip funnel, a cork puncturer, an air inlet pipe, and an air filter connection. Under the action of atmospheric pressure, the liquid in the infusion bottle flows into the drip funnel along the thinner infusion hose, and when the water column pressure in the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.
