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 ...

AI Technical Summary

Problems solved by technology

[0004] (1) There is a certain limit on the speed of infusion. When rescuing patients with severe blood loss and high risk of dehydration, rapid infusion cannot be performed, and the speed of infusion cannot be accurately controlled. For example, it is impossible to implement exactly how much medicine needs to be infused within the specified time.

[0005] (2) When the patient's infusion is left unattended and the liquid medicine is lost, it will cause blood back phenomenon, and the needle will be blocked after a long time, and it will cause trouble if the infusion is continued

[0006] (3) Hanging bottle infusion is only suitable for large-dose infusion. Although large-dose infusion is an important means to replenish body fluids and regulate body fluid balance, as a means of drug treatment, due to technical limitations, large-dose infusion is to dilute the drug to 1 / 1000. A few, or a few percent are injected into the body, and a large amount of unnecessary water is injected into the body, which is undoubtedly a great burden for some patients (such as edema patients, kidney disease patients)

During the evacuation of the wounded and sick at the front line, the low-slung means of transportation made it difficult for the conventional liquid level infusion device to successfully complete the treatment task

Due to the current clinical infusion operation procedures, the preparation procedures for infusion materials are relatively cumbersome and scattered. For example, there are only 15 pieces of materials for peripheral intravenous infusion. Fragments are inconvenient to carry and cannot adapt to the rapid march of infusion on the battlefield.

It can be seen that the preparation procedure of conventional clinical infusion materials and conventional manual inflation and pressurized infusion methods are difficult to meet the needs of rapid volume expansion and fluid replacement in wartime emergencies
