Disposable automatic heating and pressurizing transfusion device

Abstract

The invention discloses a disposable automatic heating and pressurizing transfusion device comprising a closed vessel containing sterile liquid. The disposable automatic heating and pressurizing transfusion device is characterized in that the closed vessel is internally provided with a piston which divides the closed vessel into an upper part and a lower part, wherein the capacity of the upper part is larger than that of the lower part, the upper part is a liquid bin in which the sterile liquid is closed in advance, and a vacuum chamber at the lower part is internally provided with a pressurizing device which is connected with the center of the bottom surface of the piston; a medicine adding device is arranged at one side of the top of the liquid bin, and a transfusion rubber tube is led out from the other side of the top of the liquid bin and is connected with a venipuncture needle head; and a heating device is arranged at the periphery of the radial bin wall of the liquid bin. The invention can control the transfusion quantities and the transfusion speed and automatically heat under the cold condition, has simple and convenient administration operation, flexible administration, no secondary pollution, small volume, light weight, convenient carrying, and is particularly suitable for relieving a sick or injured person in field operation and doing rescue and relief work in the field under the cold condition, thereby realizing transfusion in a narrow space.

Description

technical field

[0001] The invention relates to an integrated, disposable automatic heating and pressurizing transfusion device. It can automatically heat and pressurize the infusion in the cold field conditions, which is beneficial to the evacuation of the wounded in the field environment and improves the treatment rate. Background technique

[0002] Infusion, called intravenous drip or intravenous infusion in medical terms, is a widely used treatment. Intravenous infusion is a treatment in which large quantities of sterile solutions or drugs are given through a vein. The infusion bottle is a glass bottle with an inlet connected to the atmosphere and a rubber tube underneath. The liquid in the bottle is affected by the atmospheric pressure, so that the liquid flows into the rubber tube to form a water column. When the pressure of the water column is greater than the venous pressure, the liquid in the bottle flows into the vein smoothly. Ordinary infusion sets are mainly ...

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 Shown: a disposable automatic heating and pressurizing infusion device, including a closed container containing sterile liquid, a piston 5 is arranged in the closed container to divide the closed container into upper and lower parts, the volume of the upper part is larger than that of the lower part, and the upper part is a liquid chamber 4. The sterile liquid is pre-sealed, and the lower vacuum chamber is equipped with a pressurizing device connected to the center of the bottom surface of the piston; one side of the top of the liquid chamber is equipped with a dosing device, and the other side of the top of the liquid chamber leads out the infusion hose 12 to connect with the venipuncture needle; A heating device is arranged on the periphery of the radial direction of the liquid chamber wall.
