Description

Technical Field

[0001] The utility model relates to the field of medical devices, and in particular to a cricothyroid membrane puncture device which is easy to operate. Background Art

[0002] The cricothyroid membrane is located between the thyroid cartilage and the cricoid cartilage, with no hard covering tissue in front (only the soft thyroid gland passes through) and a ventilating tube behind. It is only a thin membrane with no vital parts around it, so it is easy to puncture.

[0003] Cricothyroidotomy is an emergency medical rescue method. This rescue technology is used when the patient cannot be intubated by conventional means, especially in emergency situations. For example, the patient has acute upper airway obstruction, the patient has laryngeal dyspnea (such as diphtheria, severe laryngeal edema, etc.), the patient has severe head and facial trauma, the patient has contraindications to endotracheal intubation or the condition is urgent and the airway needs to be opened quickly. In the above situations, the patient cannot breathe or faces the risk of suffocation. By performing cricothyroidotomy on the patient, it can help the patient quickly establish an airway when he has difficulty breathing and avoid severe airway obstruction.

[0004] However, the existing cricothyroid membrane puncture equipment requires medical personnel to effectively identify the location of the patient's cricothyroid membrane and then operate the existing cricothyroid membrane puncture equipment with both hands to perform cricothyroid membrane puncture. The operation method is not convenient enough and relies on the rescue experience of the rescue personnel. Utility Model Content
