[0002] Tracheotomy is an important measure in clinical practice to relieve airway obstruction and improve ventilation, and it plays an irreplaceable role, especially in the rescue of critically ill patients.

[0003] Currently, the low-flow oxygen therapy device used clinically for tracheostomy patients is a tracheostomy heat and moisture exchanger (artificial nose) + oxygen tubing. However, for patients who have just undergone surgery or whose disease itself causes a large amount of viscous secretions at the tracheostomy site, secretions may splash, which can easily contaminate medical staff and the patient. At the same time, secretions splashing into the tracheostomy heat and moisture exchanger can easily contaminate the heat and moisture exchange medium. Therefore, this application provides a new type of oxygen therapy device suitable for tracheostomy patients to meet the needs. Utility Model Content

[0033] like Figures 1 to 6 As shown, an embodiment of this utility model provides a novel oxygen inhalation device suitable for tracheostomy patients, including a tracheostomy heat and moisture exchange tube 1 and a pre-extension tube 3. An oxygen inhalation tube 2 is provided on one side of the tracheostomy heat and moisture exchange tube 1 for connection to a ventilator or oxygen supply equipment. Heat and moisture exchange media 6 are provided at both ends of the tracheostomy heat and moisture exchange tube 1 to simulate the heating, humidification, and filtration functions of the human upper respiratory tract. The pre-extension tube 3 is used to connect to the patient's tracheostomy tube and is internally connected to the tracheostomy heat and moisture exchange tube 1. A suction tube 5 is provided on the side wall of the pre-extension tube 3. The patient inhales oxygen by connecting to a ventilator or oxygen supply equipment through the tracheostomy heat and moisture exchange tube 1 and the pre-extension tube 3. During oxygen inhalation, secretions from the tracheostomy site caused by the patient's disease flow into the pre-extension tube 3. The suction tube 5 is connected to a negative pressure suction device, which removes the secretions collected in the pre-extension tube 3 through negative pressure suction. During negative pressure suction, the oxygen inhalation device does not need to be disconnected, avoiding repeated insertion and removal operations and reducing the workload of medical staff.

[0034] like Figure 1As shown, the heat and moisture exchange medium 6 includes a moisture-absorbing and moisturizing material layer and a filter layer. The moisture-absorbing and moisturizing material layer, made of sponge, absorbent paper, or special foam material, is used to absorb moisture and heat from the patient's exhaled air and release it during inhalation to warm and humidify the inhaled air. The filter layer, made of polypropylene film, polypropylene filter membrane, or other high-efficiency filter material, is used to filter bacteria, viruses, and particles from the inhaled air, protecting the patient's respiratory tract from contamination. Baffles 7 are provided at both ends of the tracheotomy heat and moisture exchange tube 1, with the heat and moisture exchange medium 6 located on the side of the baffles 7 facing the inside of the tracheotomy heat and moisture exchange tube 1.

[0035] like Figure 1 and Figures 4 to 6 As shown, a connector 11 is provided on the side wall of the tracheostomy heat and moisture exchange tube 1. The connector 11 and the oxygen inhalation tube 2 are symmetrically distributed. The pre-extension tube 3 is tightly fitted with the connector 11. A retaining ring 9 is provided at the end of the pre-extension tube 3 facing the tracheostomy heat and moisture exchange tube 1 to limit the connector 11. The pre-extension tube 3 and the tracheostomy heat and moisture exchange tube 1 adopt an insert-type structure, which facilitates the disassembly and cleaning and disinfection of the pre-extension tube 3 and the tracheostomy heat and moisture exchange tube 1. After the patient's secretions decrease, the pre-extension tube 3 can be removed, and the tracheostomy heat and moisture exchange tube 1 can be directly connected to the patient's tracheostomy cannula for oxygen inhalation through the connector 11. The wall of the oxygen inhalation tube 2 gradually thins away from the tracheostomy heat and moisture exchange tube 1. This structural design facilitates a tight connection between the oxygen inhalation tube 2 and the ventilator or oxygen supply equipment.

[0036] like Figures 1 to 3 As shown, the pre-extension tube 3 is located on the side of the tracheotomy heat and moisture exchange tube 1 opposite to the oxygen inhalation tube 2. The suction tube 5 is located at the bottom of the pre-extension tube 3. The end of the suction tube 5 away from the pre-extension tube 3 is bent toward the side of the pre-extension tube 3, and the end of the suction tube 5 away from the pre-extension tube 3 is fitted with a sealing cap 12. After the sealing cap 12 seals the end of the suction tube 5, the patient can inhale oxygen normally.

[0037] The bottom of the pre-extension tube 3 is provided with a bottom shell 4, which is connected to the interior of the pre-extension tube 3. The suction tube 5 is arranged at the bottom of the bottom shell 4. The cross-section of the bottom shell 4 gradually decreases away from the pre-extension tube 3, and a collection pool 10 is formed inside the bottom shell 4. A splash guard 8 is provided inside the pre-extension tube 3. The splash guard 8 is located at one end near the tracheostomy heat and moisture exchange tube 1 and inside the retaining ring 9. During oxygen inhalation, secretions from the tracheostomy site caused by the patient's disease flow into the pre-extension tube 3. Since the bottom shell 4 is arranged at the bottom of the pre-extension tube 3, the secretions can be collected in the collection pool 10 formed by the bottom shell 4 after flowing into the pre-extension tube 3. The sealing cap 12 is removed and the suction tube 5 is connected to the negative pressure suction device. The secretions collected in the collection pool 10 can be suctioned out by negative pressure suction. The splash guard 8 can prevent secretions from splashing into the tracheostomy heat and moisture exchange tube 1 and the oxygen inhalation device during oxygen inhalation.

[0038] The workflow of the technical solution provided by this utility model is as follows:

[0039] In use, the end of the pre-extension tube 3 with the splash guard 8 is tightly connected to the connector 11 on the tracheostomy heat and moisture exchange tube 1, so that the pre-extension tube 3 and the tracheostomy heat and moisture exchange tube 1 are connected. The bottom shell 4 and the suction tube 5 are distributed downwards from the pre-extension tube 3. The end of the pre-extension tube 3 away from the tracheostomy heat and moisture exchange tube 1 is connected to the patient's tracheostomy tube. The oxygen inhalation tube 2 is connected to the ventilator or oxygen supply equipment. The ventilator or oxygen supply equipment supplies oxygen to the patient through the tracheostomy heat and moisture exchange tube 1 and the pre-extension tube 3. During oxygen inhalation, secretions from the tracheostomy site caused by the patient's disease flow into the pre-extension tube 3. Since the bottom shell 4 is located at the bottom of the pre-extension tube 3, the secretions can be collected in the collection pool 10 formed by the bottom shell 4 after flowing into the pre-extension tube 3.

[0040] Remove the sealing cap 12 and connect the suction tube 5 to the negative pressure suction device. The secretions collected in the collection pool 10 can be suctioned out by negative pressure suction. The splash screen 8 can prevent secretions from splashing into the tracheostomy heat and moisture exchange tube 1 and the oxygen device during oxygen inhalation. The oxygen device does not need to be disconnected during negative pressure suction, avoiding repeated insertion and removal operations and reducing the workload of medical staff. In addition, after the patient's secretions decrease, the pre-extension tube 3 can be removed, and the tracheostomy heat and moisture exchange tube 1 can be directly connected to the patient's tracheostomy tube through the connector 11 for oxygen inhalation.

[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
