Novel blood transfusion device

Abstract

The invention discloses a novel blood transfusion device which comprises a blood bag, a connector and a blood tube. The novel blood transfusion device is characterized in that a liquid level monitoring device is arranged outside the blood bag and comprises a non-contact liquid level sensor, a single chip microcomputer and a wireless signal transmitter, both the non-contact liquid level sensor andthe wireless signal transmitter are electrically connected to the single chip microcomputer, a first guide tube and a first threaded connecting base are arranged at the bottom of the blood bag, and asecond guide tube and a second threaded connecting base are arranged at the top of the connector. The novel blood transfusion device has the advantages that liquid level is monitored by the non-contact liquid level sensor, signals are transmitted to the single chip microcomputer and then transmitted to a monitor by the wireless signal transmitter, a nurse can observe infusion conditions of a plurality of patients through a display screen of the monitor, management is facilitated, automatic blood transfusion can be realized, a flow rate alarm is given to timely remind the patients or doctors, and medical accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel blood transfusion device. Background technique [0002] In the medical field, blood transfusion devices are the most common medical devices. For the blood transfusion device, it is a key medical device to maintain the blood volume in the patient's body in an emergency. In addition to supplying blood volume, maintaining blood volume, increasing blood pressure to resist shock and preventing hemorrhagic shock, it can also supply oxygen-carrying blood. Red blood cells are used to correct acute hypoxia caused by reduced red blood cells or their reduced oxygen-carrying capacity, so blood transfusion bags can play an important role in the entire medical process. However, the existing blood transfusion devices usually lack a device for identifying blood, sometimes causing unnecessary troubles because the blood transfusion person adjusts the flow rate without authorizatio...
