DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. If not specifically specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0023] An embodiment of the present application provides an endotracheal tube, including a tracheal body 1. Around the outer peripheral wall of the tracheal body 1, an airbag 2 is provided on the tracheal body 1. The airbag 2 includes a first wall 12 near the inlet end of the tracheal body 1. Around the circumference of the first wall 12, an inflatable wall 9 is provided on the first wall 12. The inflatable wall 9 is hollow inside, and the inflatable wall 9 is communicated with the inside of the airbag 2. The first wall 12 and the inflatable wall 9 enclose a chamber structure with an opening facing the inlet end of the tracheal body 1.

[0024] The tracheal body 1 is a component for inserting into a patient's airway to enable the patient to perform pulmonary ventilation.

[0025] When the airbag 2 is inflated, on the one hand, the airbag 2 can play a role in fixing the tracheal body 1, and on the other hand, it can play a role in preventing backflow, reducing the risk of the patient's oral secretions flowing into the trachea.

[0026] The inflatable wall 9 can play a role in preventing backflow on the one hand, that is, when the inflatable wall 9 is inflated, the inflatable wall 9 can contact the inner wall of the airway, reducing the risk of the patient's oral secretions flowing into the trachea. On the other hand, the inflatable wall 9 and the first wall 12 enclose a chamber structure, and the chamber structure can receive the patient's oral secretions, facilitating subsequent cleaning, and further reducing the risk of the patient's oral secretions flowing into the trachea.

[0027] The inflatable wall 9 is communicated with the inside of the airbag 2, so that when the airbag 2 is inflated, the inflatable wall 9 can be inflated. Conversely, when the airbag 2 contracts, the inflatable wall 9 can contract.

[0028] It should be noted that the principle and operation process of how the trachea body 1 supplies air to the patient to achieve the medical effect are well-known to those skilled in the art. The technical solution of this application does not improve the air supply method of the trachea body 1 to improve the medical effect, but only involves physical improvements to the structure of the airbag 2 and the connection structure between the trachea body 1 and the breathing device. Therefore, it is not necessary to provide experimental data to prove it.

[0029] In some embodiments, the inflatable wall 9 is connected from one side of the first wall 12 to the side far from the first wall 12. The inflatable wall 9 includes a first convex section, a concave section, and a second convex section.

[0030] The second convex section plays a role in preventing backflow and guiding the flow, so that oral secretions can enter the chamber structure. The first convex section and the concave section cooperate to make the chamber structure in a state where the opening is smaller than the inside, reducing the risk of the secretions received in the chamber structure leaking out.

[0031] In some embodiments, support columns 10 are provided between the inflatable wall 9 and the first wall 12. The support columns 10 are hollow inside, and the support columns 10 are in communication with the inside of the airbag 2.

[0032] The support columns 10 can expand when the airbag 2 inflates and expands, so that the support columns 10 can support the inflatable wall 9, thereby improving the strength of the chamber structure.

[0033] In some embodiments, the support columns 10 and the inflatable wall 9 share a channel to communicate with the inside of the airbag 2.

[0034] The support columns 10 and the inflatable wall 9 sharing a channel reduces the number of openings required for the airbag 2, thereby reducing the risk of reducing the structural strength and sealing performance of the airbag 2 caused by the need to communicate the support columns 10 and the inflatable wall 9 with the inside of the airbag 2 respectively.

[0035] In some embodiments, the trachea body 1 is further provided with an extraction channel 3, and the inlet end of the extraction channel 3 is in communication with the chamber structure.

[0036] The extraction channel 3 is used to extract the secretions in the chamber structure. The extraction channel 3 can be in communication with an extraction device, so that a negative pressure can be generated in the extraction channel 3 to suck in the secretions. The extraction device can be selected from existing devices, and its structure and working principle are well-known to those skilled in the art and will not be elaborated here.

[0037] In some embodiments, the first wall 12 is hollow inside. A plurality of through holes 11 are provided on the side of the first wall 12 facing the inside of the chamber structure. The through holes 11 are in communication with the inside of the first wall 12, and the inlet end of the extraction channel 3 is in communication with the inside of the first wall 12.

[0038] The first wall 12 is hollow inside, so that a space for accommodating secretions can be formed within the first wall 12.

[0039] The secretions received by the chamber structure can enter the inside of the first wall 12 through the through hole 11 and then be extracted through the extraction channel 3. The advantage of this setting is that since the first wall 12 forms the bottom wall of the chamber structure, the inlet end of the extraction channel 3 is connected to the inside of the first wall 12, increasing the extraction effect of the secretions and enabling the secretions to be fully extracted.

[0040] In some embodiments, the tracheal body 1 is further provided with an inflation / deflation channel 4, and the inflation / deflation channel 4 is in communication with the inside of the airbag 2.

[0041] The inflation / deflation channel 4 is used to perform inflation and deflation operations on the airbag 2. The inflation / deflation channel 4 can be connected to an inflation / deflation device, enabling the airbag 2 to be inflated and deflated as needed. The inflation / deflation device can be selected from existing devices, and its structure and working principle are well-known to those skilled in the art and will not be elaborated here.

[0042] In some embodiments, a connecting pipe 8 is provided at the inlet end of the tracheal body 1, and the connecting pipe 8 is used to communicate with a breathing device.

[0043] The structure and working principle of the breathing device are well-known to those skilled in the art and will not be elaborated here.

[0044] By using the connecting pipe 8 to connect the breathing device and the tracheal body 1, the tracheal body 1 can assist or replace the patient's breathing.

[0045] In some embodiments, the connecting pipe 8 includes an insertion section 5, and the insertion section 5 is inserted into the tracheal body 1. A recessed portion is provided on the inner peripheral wall of the tracheal body 1, and a protruding portion 7 is provided on the outer peripheral wall of the insertion section 5. The protruding portion 7 is received in the recessed portion.

[0046] The insertion section 5 is inserted into the tracheal body 1, enabling the connecting pipe 8 to be detachably connected to the tracheal body 1, facilitating the replacement of the connecting pipe 8.

[0047] The cooperation of the recessed portion and the protruding portion 7 increases the connection strength between the tracheal body 1 and the insertion section 5 on the one hand, and increases the sealing effect between the tracheal body 1 and the insertion section 5 on the other hand.

[0048] In some embodiments, the connecting pipe 8 further includes a communicating section 6, and the communicating section 6 is used to communicate with the breathing device. The communicating section 6 is threadedly connected to the insertion section 5.

[0049] The connecting section 6 is threadedly connected to the inserted section 5. On the one hand, it is convenient to replace the connecting section 6 separately, reducing the use cost of the tracheal intubation. On the other hand, the connecting section 6 can change its caliber as needed, so that the tracheal intubation of the embodiment of the present application can be applicable to different breathing devices.

[0050] The above embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, variations, modifications, and replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
