Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a conveniently rotatable laryngeal anesthesia device. Background Art

[0002] Nasopharyngeal examination, gastroscopy, endotracheal intubation, bronchoscopy, etc. all need to pass through the throat. Since the human body is prone to adverse reactions such as vomiting, increased heart rate, and increased blood pressure when passing through the throat during the examination and treatment process, in order to reduce the occurrence of such adverse reactions, a laryngeal anesthesia tube is used in clinical practice for local surface anesthesia of the throat. When in use, medical staff insert the laryngeal anesthesia tube into the patient's throat in the form of blind insertion. When inserting the laryngeal anesthesia tube, the laryngeal anesthesia tube needs to be rotated and bent to adjust it to the patient's throat so that the tube can be inserted smoothly. Existing laryngeal anesthesia tubes are inconvenient to operate. Utility Model Content

[0006] The inner side of the handle ring of the utility model is provided with an elastic buffer layer.

[0007] Preferably, the elastic buffer layer is elastic cotton.

[0008] The docking port of the syringe of the utility model is provided with a raised locking ring at one end close to the barrel, the outer side of the docking port is provided with an external thread, the inner side of the joint is provided with an internal thread, and the inner side of the end of the joint is provided with a locking groove corresponding to the locking ring.

[0009] The two handle rings of the utility model are relatively mounted on the ring sleeve, the ring sleeve is provided with internal threads, and the barrel of the syringe is provided with matching external threads at one end away from the docking port.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model arranges a shaped steel wire in the tube wall of the laryngeal anesthesia tube. When in use, the drug solution will not flow through the steel wire, thus preventing the steel wire from being corroded and affecting health. A handle ring is arranged on the barrel of the syringe, which is convenient for holding the barrel and rotating it to adjust the angle of the laryngeal anesthesia tube. The liquid discharge mode of the laryngeal anesthesia tube adopts spraying, so that the drug discharge is uniform.

[0012] 2. The utility model provides an elastic buffer layer on the inner side of the handle ring, which reduces the pressure on the fingers when the hand-held ...

[0013] 3. The joint of the laryngeal anesthesia tube adopts a threaded connection, and a raised locking ring is added to the docking port of the syringe. The corresponding locking groove on the docking head is used to achieve the card connection, so that the two can be firmly sealed and connected, and it is not easy to fall out when rotated for a long time.
