Problems solved by technology

However, most of the existing pressurization devices use constant pressure, which causes the blood flow rate to be stable and inconvenient. If the flow rate is too large, it will cause discomfort to the patient, and even if the patient is unconscious, the body will also have some stress reactions, which is easy Interfere with treatment, and in severe cases, aggravate the condition

Abstract

A pulsatile blood transfusion device, including a conduit for connecting a blood bag and a blood transfusion needle, a constriction part and an expansion part are sequentially arranged in the middle part of the upper conduit from the blood bag to the blood transfusion needle, and the expansion part is provided on the side for periodic squeezing. Squeeze mechanism for compression expansion. The invention provides a pulsatile blood transfusion device, which can simulate the normal blood supply process of the heart, thereby alleviating the patient's discomfort and avoiding the stress response generated by the patient's body from aggravating the patient's condition.

Description

Technical field[0001]The present invention relates to the field of blood transfusion devices, and is specifically a pulsating transfusion device.Background technique[0002]Blood transfusion is a rescue means commonly used during medical treatment, mainly used for patients with blood loss. In the prior art, in order to overcome the resistance of the blood vessels to ensure smooth blood transfusion process, a pressurizing device is usually added, and the blood pressure and flow rate are improved. However, most of the existing pressurized devices use constant pressure, which results in a stable and inconvenient flow rate. If the flow rate is too large, it will cause discomfort in patients, and some patients will appear some should have some should have some should have some stress reactions. Interference treatment, seriously aggravated the condition.Inventive content[0003]In order to solve the deficiencies in the prior art, the present invention provides a pulsating transfusion device t...
