Description

Metal autogenous cutting sleeve with air bag

Technical Field

The invention belongs to the technical field of medical instruments, and relates to an autogenous cutting sleeve for reducing airway pollution and suffocation risk.

Background

Tracheotomy is a common operation to relieve dyspnea caused by laryngeal dyspnea, respiratory dysfunction or lower respiratory secretions retention.

An artificial airway is required to be established after tracheotomy. Currently, artificial airways mainly comprise a single catheter with a balloon and a double cannula without a balloon. The single catheter with the air bag is usually made of plastic, the soft air bag is arranged at the tail end of the catheter, the function of closing an air passage can be achieved during inflation, the single catheter can be connected with a breathing machine for mechanical ventilation, side holes are reserved above some air bags and used for sucking and removing secretions on the air bags, and lung infection caused by aspiration is reduced. However, the secretion is apt to block the catheter tube and cause asphyxia, so that it is not suitable for long-term retention. The double sleeves without the air bags are usually made of metal and comprise outer sleeves, tube cores and inner sleeves, the tube cores assist the outer sleeves to be placed into the air passages, the inner sleeves are placed into and fixed in the outer sleeves, the inner sleeves are periodically detached to clean and disinfect, the air passage pollution can be reduced, the phenomenon that the secretion blocks the pipeline to cause asphyxia is avoided, the catheters do not have the air bags, cannot be connected with a breathing machine to conduct mechanical ventilation, and the secretion of the upper respiratory tract and the content of the stomach are easily sucked by mistake to cause lung infection.

Furthermore, the tube core is made of metal materials and comprises a core tail and a core head, the tube core is slightly longer than the outer sleeve, and the core tail is bullet-shaped; when the tube is placed, the tube core is inserted into the outer tube, the core head is clamped in the opening of the outer tube head, the front part of the core tail is exposed out of the opening of the outer tube, and the neck tissues of a patient are separated from the trachea by holding the outer tube and the tube core in a blunt manner.

Further, the inner sleeve is made of metal materials and comprises an inner pipe, an inner pipe head and a pipe cap; the inner pipe is as long as the outer pipe, and the outer diameter of the inner pipe is slightly smaller than the inner diameter of the outer pipe; the outer diameter of the inner pipe head is the same as that of the outer pipe head, threads are arranged on the surfaces of the inner pipe head and the outer pipe head, and the directions of the threads are consistent; the pipe cap is a hollow cylinder and slightly larger than the inner pipe head, the inner wall of the pipe cap is provided with threads, the threads are matched with the threads of the inner pipe head and the outer pipe head, and the inner pipe head and the outer pipe head are fixed by rotating the pipe cap.

The utility model has the advantages that: the utility model is provided with the air bag, can be connected with a breathing machine pipeline for mechanical ventilation, and simultaneously reserves the suction tube opening above the air bag, and sucks the secretion detained above the air bag by negative pressure, thereby reducing the lung infection caused by secretion aspiration; in addition, because be double cannula, interior sleeve pipe can be dismantled at any time and wash, disinfect, avoids secretion to block up the pipe and arouses the suffocation, reduces the air flue and pollutes, and overcoat intraductal wall and interior sleeve pipe are metal material, and the contact surface is smooth, and the laminating degree is good, easily dismantles, and the disinfection is simple and convenient, non-deformable, and convenient disinfection or the nursing of being in hospital at home are used by oneself.
