Description

A kind of personalized drug delivery device for anesthetic drugs

Technical field

The utility model belongs to the technical field of drug delivery devices, and specifically relates to an individualized drug delivery device for anesthetic drugs.

Background technique

The personalized drug delivery device is a medical device designed to achieve personalized drug management for patients' anesthesia treatment.

The anesthesia needle currently used clinically is a disposable syringe, which is composed of a needle body and a needle handle. However, this anesthetic needle has some problems when anesthetizing patients, causing trouble to patients and medical staff.

First, it is difficult to control the depth of puncture with this anesthetic needle, causing patients to often suffer additional pain during the anesthesia process. Due to the inability to accurately control the puncture depth, medical staff may enter too deep into the tissue layer when injecting drugs, causing accidents and causing unnecessary harm to the patient. This inaccuracy also increases treatment uncertainty and reduces the safety and efficiency of the procedure. Secondly, the needle body is prone to shaking, which makes the puncture operation more difficult. A wobbly needle makes it difficult to precisely control its position, making accurate puncture difficult, especially when positioning in a specific tissue or organ is required. This instability brings additional work difficulty to medical staff and increases operational risks and uncertainties. In addition, when anesthetizing a patient, multiple punctures and needle insertions are usually required so that the anesthetic can quickly spread to the area where it needs to act. This process is very troublesome, time-consuming and labor-intensive. It not only increases the operation time and discomfort of the anesthesia process, but also adds a lot of repetitive work burden to medical staff, reducing efficiency and comfort.
