Description

Technical Field

[0001] The invention relates to the technical field of tracheal cannulae, in particular to a spliced ​​endotracheal cannula. Background Art

[0002] Tracheotomy is a common surgery to relieve dyspnea caused by laryngeal origin, abnormal respiratory function or retention of lower respiratory tract secretions. It requires the use of a tracheal cannula, which consists of an outer cannula and an inner cannula.

[0003] The endotracheal tube needs to be cleaned and disinfected after use. After cleaning, the inner tube needs to be inspected to check for blood stains, scale, rust spots, etc. to ensure its function is intact and without damage.

[0004] Since all endotracheal tubes are arc-shaped structures, the endotracheal tubes available on the market are very inconvenient to clean and inspect. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In order to solve the above problems in the prior art, the present invention provides a spliced ​​endotracheal tube, which is convenient for cleaning and inspecting the endotracheal tube.

[0007] (II) Technical solution

[0008] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0009] A spliced ​​endotracheal tube comprises an upper tube, a lower tube and a sleeve, wherein the upper tube can be drawn out from the right end of the lower tube, a slot is arranged at the right end of the outer wall of the upper tube and the lower tube, and a snap mechanism used in conjunction with the slot is arranged inside the sleeve, so as to facilitate the cleaning and inspection of the endotracheal tube.

[0010] Preferably, the engaging mechanism comprises a spring and a pressure ball, and the pressure ball is used in conjunction with the engaging slot.

[0011] Preferably, the upper half tube and the lower half tube are connected via a sliding groove and a sliding block.

[0012] (III) Beneficial effects

[0013] The present invention provides a spliced ​​endotracheal tube, which has the following beneficial effects:

[0014] (1) The sleeve, upper half pipe and lower half pipe can be disassembled and cleaned separately, which is convenient for cleaning and there is no dead corner for cleaning.

[0015] (2) You can pull a section of the upper half of the tube out from the lower half of the tube, and then check the inner wall of the lower half of the tube, and then turn it over to check the inner wall of the upper half of the tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, the spliced ​​endotracheal tube of this embodiment includes an upper half tube 1, a lower half tube 2 and a sleeve 3. The upper half tube 1 can be pulled out from the right end of the lower half tube 2. The upper half tube 1, the lower half tube 2 and the sleeve 3 can be separated for easy cleaning and inspection. A clamping groove 4 is provided at the right end of the outer wall of the upper half tube 1 and the lower half tube 2, and a clamping mechanism 5 used in conjunction with the clamping groove 4 is provided inside the sleeve 3. The clamping mechanism 5 can realize quick disassembly and quick assembly.

[0022] As a specific implementation of the present invention, the engaging mechanism 5 includes a spring 501 and a pressure ball 502 , and the pressure ball 502 is used in conjunction with the engaging slot 4 .

[0023] As a specific implementation of the present invention, the upper half pipe 1 and the lower half pipe 2 are connected via a sliding groove and a sliding block.

[0024] Working principle: When disassembly and cleaning is required, firstly, the sleeve 3 is pulled out forcefully toward the opposite side of the upper half tube 1 and the lower half tube 2. During the pulling out process, the card slot 4 will squeeze the pressure ball 502, and the pressure ball 502 will squeeze the spring 501. The spring 501 is compressed and the sleeve 3 is pulled out. Then, the upper half tube 1 is slid toward the right end of the lower half tube 2 to separate the upper half tube 1 and the lower half tube 2. Then, the upper half tube 1 and the lower half tube 2 are cleaned and inspected. After the cleaning and inspection is completed, the upper half tube 1 is inserted into the lower half tube 2, and then the sleeve 3 is inserted.
