Description

Technical Field

[0001] This utility model relates to the field of gas cutting sleeve technology, and in particular to a novel metal gas cutting sleeve. Background Technology

[0002] A tracheostomy tube is a medical device commonly used in emergencies to maintain an open airway in patients with hypoxemia. It is typically made of polyurethane and consists of an outer cannula and an inner cannula. The outer cannula is inserted into the tracheal cavity after a tracheotomy, while the inner cannula can be connected to a ventilator or used to manually maintain breathing. Tracheostomy tubes can be used in emergency situations where oxygen deficiency is caused by airway obstruction, severe trauma, anaphylactic reactions, or other reasons. Before use, it must be under the strict guidance of a professional and the tube must be cleaned and sterilized using sterilization equipment.

[0003] While existing metal tracheostomy cannulas can meet clinical needs, their drawbacks are also apparent in certain scenarios. During endoscopic procedures, when the flexible endoscope is inserted into the metal tracheostomy cannulas, it occupies the tubing space, preventing the oxygen tubing from entering. This means that patients who would normally be ventilated using a metal tracheostomy cannulas cannot receive sufficient oxygen. Therefore, a new type of metal tracheostomy cannulas is needed to meet these requirements. Utility Model Content

[0004] The purpose of this invention is to provide a novel metal gas cutting sleeve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel metal gas cutting sleeve, comprising a fixed base, an outer sleeve, an arc-shaped throat, and an arc-shaped inner tube. The outer sleeve is disposed at one end of the fixed base, and the arc-shaped throat is disposed at the other end of the fixed base and communicates with the outer sleeve. The arc-shaped inner tube is arranged inside the outer sleeve, the fixed base, and the arc-shaped throat. The arc-shaped inner tube and the outer sleeve are movably connected by a limiting member. An oxygen delivery channel is provided on the inner arc wall of the arc-shaped throat, extending through to the end of the arc-shaped throat connected to the fixed base and passing through the fixed base. An air intake tube is provided on the fixed base, and the air intake tube communicates with the oxygen delivery channel.

[0006] Preferably, the fixing base has connection holes on both sides.

[0007] Preferably, the limiting component consists of a limiting pin and a rotating ring. The limiting pin is T-shaped, with one end of the shaft with a smaller outer diameter connected to the end face of the outer sleeve. The rotating ring is rotatably connected to the outer wall of the arc-shaped inner tube, and a groove is provided on the outer wall. The groove diameter is larger than the outer diameter of the shaft with a larger outer diameter than the limiting pin.

[0008] Preferably, an air bladder is provided on the outer wall of the end of the arc-shaped throat tube away from the fixed seat. An inflation tube is connected to the air bladder. The inflation tube is arranged along the outer arc of the arc-shaped throat tube and extends outward through the fixed seat. An inflation bladder is connected to the inflation tube.

[0009] Preferably, the air intake pipe is equipped with a one-way valve.

[0010] Preferably, the one-way valve is equipped with a pressure regulating valve.

[0011] The beneficial effects of this utility model are:

[0012] This invention effectively avoids the space occupied by inserting an oxygen tube into the arc-shaped larynx by adding an oxygen delivery channel on the outer wall of the larynx, thus achieving a relatively independent oxygen delivery channel. Oxygen can be delivered by connecting the oxygen supply device to the ventilation tube, thereby ensuring that the patient receives sufficient oxygen during endoscopic procedures. Furthermore, by opening the oxygen delivery channel on the inner arc of the arc-shaped larynx, space can be effectively saved, and discomfort to the patient's wound caused by adding a tube can be avoided.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4 A novel metal tracheostomy sleeve includes a fixed base 1, an outer sleeve 2, an arc-shaped throat 3, and an arc-shaped inner tube 4. The outer sleeve 2 is disposed on one end of the fixed base 1, and the arc-shaped throat 3 is disposed on the other end of the fixed base 1 and communicates with the outer sleeve 2. The arc-shaped inner tube 4 is arranged inside the outer sleeve 2, the fixed base 1, and the arc-shaped throat 3. The arc-shaped inner tube 4 and the outer sleeve 2 are movably connected by a limiting member 5. An oxygen delivery channel 6 is provided on the inner arc wall of the arc-shaped throat 3. The oxygen delivery channel 6 extends through the end of the arc-shaped throat 3 connected to the fixed base 1 and passes through the fixed base 1. An air intake tube 7 is provided on the fixed base 1 and communicates with the oxygen delivery channel 6.

[0020] By adding an oxygen delivery channel 6 to the outer wall of the arc-shaped larynx 3, the space occupied by the oxygen tube inserted into the arc-shaped larynx 3 is effectively avoided. The oxygen delivery channel 6 is relatively independent and can be connected to the ventilation tube 7 through the oxygen supply device to deliver oxygen. This ensures that the patient receives sufficient oxygen during endoscopic procedures. Furthermore, by opening the oxygen delivery channel 6 on the inner arc wall of the arc-shaped larynx 3, space can be effectively saved, the curvature of the original arc-shaped larynx 3 can be preserved, and discomfort to the patient's wound can be avoided by adding a tube.

[0021] Specifically, in this embodiment, the fixing seat 1 has connecting holes 8 on both sides for threading a connecting strap, so that the fixing seat 1 together with the tracheostomy tube can be worn on the patient's neck.

[0022] Specifically, in this embodiment, the limiting member 5 consists of a limiting pin 9 and a rotating ring 10. The limiting pin 9 is T-shaped, with one end of the shaft with a smaller outer diameter connected to the end face of the outer sleeve 2. The rotating ring 10 is rotatably connected to the outer wall of the arc-shaped inner tube 4, and a slot 11 is provided on the outer wall. The diameter of the slot 11 is larger than the outer diameter of the shaft with a larger outer diameter of the limiting pin 9, which is used to achieve a stable connection of the arc-shaped inner tube 4 in the air-cutting sleeve and to remove and clean it. During installation, the rotating ring 10 is rotated to align the slot 11 with the limiting pin 9, and the arc-shaped inner tube 4 is pushed so that the rotating ring 10 moves from the shaft with a larger outer diameter of the limiting pin 9 to the shaft with a smaller outer diameter. The rotating ring 10 is rotated again so that the position of the slot 11 deviates from the limiting pin 9. At this time, the outer wall of the rotating ring 10 itself enters the shaft with a smaller outer diameter of the limiting pin 9 and is limited by the shaft with a larger outer diameter, so that the removal of the rotating ring 10 and the arc-shaped inner tube 4 from the air-cutting sleeve is restricted, thereby achieving a stable connection.

[0023] Specifically, in this embodiment, an air bladder 12 is provided on the outer wall of the end of the arc-shaped larynx 3 away from the fixing seat 1. An inflation tube 13 is connected to the air bladder 12. The inflation tube 13 is arranged along the outer arc of the arc-shaped larynx 3 and extends outward through the fixing seat 1. An inflation bladder 14 is connected to the inflation tube 13 to reduce the discomfort caused when the arc-shaped larynx 3 is inserted into the patient's bronchus. After the arc-shaped larynx 3 is inserted, it can be continuously inflated by the inflation bladder 14. The air bladder 12 expands through the inflation tube 13, thereby supporting it between the patient's bronchus and the arc-shaped larynx 3.

[0024] Specifically, in this embodiment, a one-way valve 15 is provided on the airway 7 to prevent backflow of mucus or blood and improve operational safety.

[0025] Specifically, in this embodiment, a pressure regulating valve 16 is provided on the one-way valve 15, which can adjust the oxygen supply according to the real-time needs of bronchoscope operation, thereby reducing oxygen waste or excess.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
