Switch device for plugging of inner sleeve during tracheostomy

Abstract

The invention aims to provide a simple and convenient switch device for plugging of an inner sleeve. The switch device can open or close a trachea passage at any time and comprises the inner sleeve and a sleeve cap fixedly connected with the outer end of the inner sleeve, wherein a switch device body is arranged on one side between the sleeve cap and the outer end of the inner sleeve; and according to the switch device body, a small hole and a matched plug pin are arranged on one side between the sleeve cap and the outer end of the inner sleeve, two parallel round sheets are fixed to the two ends of the plug pin, one round sheet is arranged in the inner sleeve, and the diameter of the round sheet is the same as the inner diameter of the inner sleeve.

Description

technical field [0001] The invention relates to a medical auxiliary device, especially a sealing switch device for a tracheotomy inner casing. Background technique [0002] Tracheotomy is to incise the trachea of ​​the neck and put in a metal tracheal cannula and a silicone cannula. It is a common operation to relieve dyspnea caused by laryngeal origin, respiratory dysfunction or retention of secretions in the lower respiratory tract, hereinafter referred to as trachea. cut. Indications: [0003] 1. Laryngeal obstruction: severe laryngeal obstruction caused by laryngeal inflammation, tumor, trauma, foreign body, etc. [0004] 2. Retention of secretions in the lower respiratory tract: For the retention of secretions in the lower respiratory tract due to various reasons (cranial brain trauma, thoracic and abdominal trauma, and poliomyelitis, etc.), tracheotomy may be considered in order to suck sputum and keep the airway unobstructed. [0005] 3. Preventive tracheotomy: Pha...

Problems solved by technology

[0008] When in use, the inner cannula is in an open state, and the patient's breathing passes through this passage instead of the mouth and nose. However, sometimes the patient's condition recovers and it is necessary to temporarily block this passage to exercise the patient's spontaneous breathing ability. Usually gauze or cork or syringe cap is used to block, not to mention the waste of medical supplies, the blocking effect is not good, and it is inconvenient to use force when taking out the blockage, which will touch the patient's wound
