T-shaped air-vent trocar for thyrocricocentesis

Abstract

The invention provides a T-shaped air-vent trocar for thyrocricocentesis. The trocar comprises a T-shaped air tube and an air tube core, wherein a standard respirator adapter is arranged at one end of the T-shaped air tube; an outer trocar is connected at the other end of the T-shaped air tube in a sealing manner; the diameter of the T-shaped air tube is smaller than that of the standard respirator adapter; a standard oxygen tube adapter communicated with a cavity inside the T-shaped air tube is also arranged on the body of the T-shaped air tube; a fixed wing which can be fixed on the human body is arranged at the joint of the T-shaped air tube and the outer trocar; a puncture needle with diameter smaller than the inner diameter of the outer trocar is arranged at the end of the air tube core; a rubber seal ring with inner diameter greater than that of the T-shaped air tube is arranged at the joint of the air tube core and the puncture needle; and the air tube core is inserted in the T-shaped air tube and is sealed with the inner wall of the T-shaped air tube by the rubber seal ring. The trocar has light structure, can be put in each first aid place or first aid box for standby application and really achieves gizmo with big functions.

Description

technical field [0001] The invention relates to a medical first aid appliance, in particular to a T-shaped ventilation trocar for cricothyroid membrane puncture. Background technique [0002] As we all know, the human body cannot tolerate hypoxia, and severe hypoxia lasting for several minutes can lead to irreversible damage to the body. During on-site first aid, when the patient cannot guarantee effective spontaneous breathing and face mask pressurization ventilation cannot improve the hypoxic state, an artificial airway must be established urgently. At present, the establishment of artificial airway mainly includes tracheal intubation, tracheotomy, cricothyroidotomy and cricothyroidotomy and other techniques. Because the operation steps of the three techniques of tracheal intubation, tracheotomy and cricothyrotomy are relatively complicated, in an emergency, even professionally trained personnel cannot guarantee that they can be successfully completed in a short time, so ...

AI Technical Summary

Problems solved by technology

The ventilation mode that this type of kit can carry out is relatively single, and it is easy to cause respiratory resistance when performing assisted ventilation on patients with spontaneous breathing, so it cannot effectively improve the hypoxic state

However, due to the lack of an oxygen delivery tube interface, oxygen cannot be delivered effectively to patients who retain their spontaneous breathing, so the improvement of the patient's hypoxic state is limited.

In addition, this type of kit lacks an exhaust port. When controlling the ventilation of a patient with upper airway obstruction, the air in the patient's lungs cannot be effectively removed, which may easily lead to airway pressure injury.

The other type is the multi-function kit. In addition to the respirator interface, this type of kit also has devices such as a skin cutter and a suction tube. The design of this type of kit is relatively complicated, and it is not easy for on-site emergency personnel to correctly grasp how to use it. As a result, the precious first aid time is often delayed, resulting in the occurrence of hypoxic damage in patients.
