Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laryngoscopes, in particular to a disposable laryngoscope blade. Background Art
[0002] Laryngoscope is an important medical device for the anesthesiology, emergency and throat departments of hospitals. With the development of technology, video laryngoscopes have been used more and more. However, video laryngoscopes are expensive and cannot be used as disposable devices. In order to adapt to the requirements of patients with weak immune systems and hospital infection control, disposable laryngoscope blades have been produced. Putting a disposable laryngoscope on the blade can effectively avoid infection problems. Disposable laryngoscope blades are usually made of hard plastic, and each person's throat structure is different.
[0003] The visual laryngoscope blades in the prior art still have some defects when used. For example, the catheter on the outer surface of the laryngoscope does not have a clamping structure, which makes it unstable during use and prone to accidents. The laryngoscope cannot adjust its position. When the patient lies in a supine position, the endotracheal intubation is performed and then the patient is changed to a lateral position. Since muscle relaxants are required for induction of general anesthesia, changes in body position without muscle protection are prone to iatrogenic injuries to important parts such as the cervical spine, which undoubtedly increases the risk for the patient. For this reason, we have proposed a disposable laryngoscope blade. Utility Model Content
