Embodiment Construction

[0036] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] In one embodiment of the present invention, as Figure 1-7 As shown, a trachea tube adapter is provided, including a cylindrical adapter 1, the inner wall of the adapter 1 is provided with a number of annular ribs 2, the inner diameter of the annular ribs 2 gradually decreases from bottom to top, and the annular ribs The ribs 2 are integrally formed, and an annular groove 3 is formed between two adjacent annular ribs 2. The diameter of the annular groove 3 decreases gradually from bottom to top, and a protruding tube is provided on the side wall of the adapter. Optimally, the material of the annular rib 2 is rubber or silicone with deformability.

[0038] Optimally, it also includes a double-layer cover 4. Optimally, the double-layer cover 4 includes an inner cover 6 and an outer cover 7. The inner cover 6 is arranged inside the ou...

Abstract

The invention discloses a tracheal cannula adapter and a tracheal cannula. The tracheal cannula adapter comprises a cylindrical adapter head; a plurality of annular flanges are arranged on the inner wall of the adapter head; the inner diameter of each annular flange is gradually reduced from bottom to top; the annular flanges are integrally formed; an annular groove is formed between every two adjacent annular flanges; and the diameter of each annular groove is gradually reduced from bottom to top. The trachea cannula adapter can effectively solve the problems that an existing metal trachea cannula is diverse in size and cannot be connected with different instruments such as a breathing machine, a breathing air bag, a disposable heat and moisture exchanger and a filter for use.

Description

technical field [0001] The invention belongs to the technical field of trachea tube adapters, and in particular relates to a trachea tube adapter and a trachea tube. Background technique [0002] Tracheotomy is the most effective measure to relieve airway obstruction and improve ventilation function when rescuing critically ill patients, and it can improve dyspnea caused by various reasons. At present, the most commonly used tracheal cannula after tracheotomy includes metal cannula and plastic cannula. In comparison, the two types of cannula have their own advantages and disadvantages. The metal cannula is low in cost, complete in size, small in size, and has good compatibility with surrounding tissues, but the nursing workload is relatively large; the mouth of the plastic cannula and the mouth of the ventilator can easily Connected to buy time for rescue, and more conducive to other rehabilitation of patients. The metal trachea casing consists of three parts: the outer tu...
