Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drug injection, in particular to an ultrasound-guided drug injection device. Background Art
[0002] Ultrasound technology is a means of perioperative diagnosis and treatment. Currently, in clinical practice, nerve block needles and injection components are mostly connected through extension tubes. When doctors perform nerve block trial injections on patients, one of them holds the ultrasound probe in one hand to the area of the patient's body that needs anesthesia, so that the corresponding area that needs anesthesia is displayed on the display screen, and the other hand holds the nerve block puncture needle to puncture the corresponding area that needs anesthesia. After the puncture is in place, the other person holds the injection component to push the anesthetic solution. During this process, both people need to concentrate and cooperate with each other.
[0003] If the two people do not cooperate well, the nerve block trial injection will take a long time, and may even cause operational errors, resulting in secondary damage to the patient's nerves and blood vessels and local anesthetics being mistakenly injected into blood vessels, causing local anesthetic poisoning, which will harm the patient. In addition, when there are insufficient manpower, insufficient hospital ratios, or difficult field conditions, it is impossible for a single person to complete the operation, which wastes human resources and is inconvenient. Therefore, the role of an injection device that can be operated by a single person is reflected. Since different types of syringes are required according to the type of injected drugs, the injection device needs to be able to fix different types of syringes. Utility Model Content
