Description
Technical Field
The utility model relates to a metal autogenous cutting sleeve with a standard caliber, and belongs to the technical field of medical instruments.
Background
The exposed joint of the inner sleeve of the existing metal autogenous cutting sleeve is not cylindrical and has an irregular caliber (shown in figure 1), the shape and caliber of the exposed joint are not matched with those of a connecting pipeline of a conventional oxygen inhalation device or an atomization device, the exposed joint cannot be directly externally connected with a heating and humidifying high-flow oxygen inhalation device or an atomization device, and oxygen supply or atomization treatment of a conventional autogenous cutting mask cannot be directly connected with the sleeve, so that the treatment efficiency is poor.
In addition, if a patient wearing the tracheostomy metal sleeve needs to plug the sleeve, no matched part exists, a clinician usually searches a cork or a syringe tail with similar size to plug a metal hole, but the phenomena of inward sinking and outward falling often occur, and the plugging effect is poor.
Disclosure of Invention
The technical problems to be solved by the utility model are as follows: the shape and caliber of the exposed joint of the inner tube of the existing metal autogenous cutting sleeve pipe are not matched with the connecting pipelines of the oxygen inhalation device and the atomizing device, the exposed joint cannot be directly connected with the connecting pipelines, and the technical problems of inconvenient plugging and the like are solved.
In order to solve the technical problems, the utility model provides a metal autogenous cutting sleeve with a standard caliber, which comprises an inner sleeve and an outer sleeve, wherein the inner sleeve is provided with an exposed joint, and the exposed joint is in a cylindrical shape with the standard caliber.
Preferably, the outer diameter of the interface of the exposed joint is set to 14mm.
Preferably, the exposed joint is provided with a pipe cap for plugging, and the exposed joint and the pipe cap are in embedded connection.
Preferably, the extension part of the exposed joint is provided with two symmetrical holes, and the extension part of the pipe cap is provided with a protrusion for jogging connection with the holes on the exposed joint.
Preferably, the surfaces of the inner sleeve and the outer sleeve are respectively provided with a polytetrafluoroethylene coating.
Compared with the prior art, the utility model has the beneficial effects that:
1. the metal autogenous cutting sleeve pipe is provided with the exposed joint with the cylindrical standard caliber, can be directly connected with the oxygen inhalation device or the atomization device, can effectively improve the effectiveness of oxygen therapy and atomization therapy of an autogenous cutting patient, and increases the universality of equipment;
2. furthermore, the metal autogenous cutting sleeve pipe is provided with the embedded pipe cap, so that the sealing is convenient when the pipe is sealed, the sealing performance is good, the metal autogenous cutting sleeve pipe is not easy to separate, and the safety can be improved;
3. furthermore, the inner sleeve and the outer sleeve of the metal autogenous cutting sleeve provided by the utility model have the advantages that the polytetrafluoroethylene coating is arranged on the inner surface and the outer surface of the sleeve, so that the metal autogenous cutting sleeve has better high lubrication and non-tackiness, the deposition of pathogens such as sputum and the like, bacteria, fungi and the like on the metal sleeve can be reduced, and the occurrence of respiratory tract and lung infection of an autogenous cutting patient is reduced.

FIG. 1 is a schematic view of a prior art metal autogenous cutting sleeve with the outer tube on the left and the inner sleeve on the right;
FIG. 2 is a standard gauge metal autogenous cutting sleeve of the present utility model;
reference numerals: 1. an outer tube; 2. an inner sleeve; 3. an exposed joint; 4. a tube cap; 5. a hole; 6. a protrusion.
Detailed Description
In order to make the utility model more comprehensible, preferred embodiments accompanied with figures are described in detail below.
Examples
The utility model provides a metal autogenous cutting sleeve pipe of standard bore, shown in figure 1, includes outer tube 1 and interior sleeve pipe 2, and its interior sleeve pipe 2 is equipped with exposes and connects 3, expose and connect 3 for cylindrical and for standard bore (current pipeline's standard bore includes 14mm, 19mm, 24mm, 29mm and 34 mm), expose and connect 3 to be equipped with the pipe cap 4 that is used for the shutoff, the extension department that exposes connects 3 is equipped with two symmetrical holes 5, the extension department that exposes the pipe cap 4 is equipped with the protruding 6 that is used for jogged connection with the hole that exposes to connect 3, and the exposure connects 3 and pipe cap 4 can mutually jogged in order to reach totally airtight, and metal resistance is big, can not receive patient cough air current influence and the pipe cap separation.
Preferably, the diameter (interface outer diameter) of the exposed joint 3 is set to 14mm, and the joint can be connected to a pipeline of an existing conventional oxygen inhalation device or an atomization device.
Preferably, polytetrafluoroethylene coatings (spraying mode) without perfluoro caprylic acid are arranged on the inner and outer surfaces of the inner sleeve and the outer sleeve of the metal autogenous cutting sleeve, and the thickness of the polytetrafluoroethylene coatings is set to be 0.4-0.6 mm, so that the metal autogenous cutting sleeve has better high lubrication and non-tackiness, and can reduce the deposition of sputum and other secretion, bacteria, fungi and other pathogens on the metal sleeve, and reduce the occurrence of respiratory tract and lung infection of autogenous cutting patients.
The above embodiments are only preferred embodiments of the present utility model, and are not limited in any way and in essence, and it should be noted that modifications and additions may be made to those skilled in the art without departing from the scope of the utility model.
