[0002] Total laryngectomy is a commonly used surgery to treat laryngeal diseases such as laryngeal cancer. After total laryngectomy, the patient's trachea is directly opened, forming a permanent tracheostomy (referred to as tracheostomy) in the front of the neck, which causes the loss of the natural heating, humidification, and filtering functions of the upper respiratory tract, leading to the inhalation of dry and cold air through the stoma, and sputum is prone to crusting. In addition, after laryngectomy, the patient's breathing route and expectoration method are changed, and the trachea is prone to dry bleeding, sputum and other problems. Therefore, patients with tracheostomy need to inhale humidified oxygen after surgery to relieve upper respiratory tract discomfort.

[0039] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figure 1-Figure 3 As shown, an oxygen supply device for patients with tracheostomy in a preferred embodiment of the utility model comprises a tubular airbag 1 and an adhesive strip 2. The tubular airbag 1 is provided with an air inlet and outlet passage connected from the first end of the tubular airbag 1 to the second end of the tubular airbag 1. The first end of the tubular airbag 1 is an elliptical ring, and the air inlet and outlet passage has a first air inlet and outlet port 11 located at the first end of the tubular airbag 1 and a second air inlet and outlet port 12 located at the second end of the tubular airbag 1. It can be understood by those skilled in the art that the first air inlet and outlet port 11 is an elliptical shape, and the second air inlet and outlet port 12 is a circular shape. The first air inlet and outlet port 11 is used to connect the tracheostomy of the patient. The outer wall of the tubular airbag 1 is provided with an air charging and discharging tube 13, a plugging member 14 for closing the air charging and discharging tube 13, and an oxygen inlet passage connecting the air inlet and outlet passage and the outside of the tubular airbag 1. In this embodiment, the plugging member 14 is a sealing cock, and the plugging member 14 is connected to the outer wall of the air charging and discharging tube 13 through a soft plastic connecting strip. The adhesive strip 2 is disposed at the first end of the tubular airbag 1 and surrounds the first air inlet and outlet 11 , and is used to bond the tubular airbag 1 to the neck skin of the patient.

[0041] The oxygen supply device for tracheostomy patients provided in this embodiment is used for oxygen supply to tracheostomy patients. The second air inlet and outlet 12 of the tubular airbag 1 is connected to the air. The patient can inhale air and exhale waste gas through the second air inlet and outlet 12 of the tubular airbag 1, and the humidified oxygen enters the air inlet and outlet through the oxygen air inlet on the side wall of the tubular airbag 1, and then enters the patient's tracheostomy through the first air inlet and outlet 11 together with the air. The first end of the tubular airbag 1 is used to connect the patient's neck. Specifically, the first end of the tubular airbag 1 is bonded to the skin around the patient's tracheostomy through the adhesive strip 2, and the patient feels less uncomfortable. The first end of the tubular airbag 1 is an elliptical ring. When the tubular airbag 1 is connected to the patient's neck, the long axis of the elliptical ring is along the radial direction of the patient's neck, and the short axis of the elliptical ring is along the length direction of the patient's neck, so that the first end of the tubular airbag 1 is easier to fit with the patient's neck, and has a better fitting effect for fatter and thinner patients. And the adhesive strip 2 surrounds the first air inlet and outlet 11 of the tubular airbag 1, thereby improving the air tightness of the connection between the tubular airbag 1 and the patient's neck. In addition, an inflation and deflation air tube 13 is provided on the side wall of the tubular airbag 1. The tubular airbag 1 is inflated and deflated by the inflation and deflation air tube 13, and the gas pressure in the tubular airbag 1 can be adjusted, thereby adjusting the surface hardness of the tubular airbag 1, so that the tubular airbag 1 can better fit the necks of different patients. For example, for patients with a smaller neck diameter, that is, a larger neck surface curvature, the gas pressure in the tubular airbag 1 can be appropriately smaller, so that the surface hardness of the tubular airbag 1 is reduced, and the tubular airbag 1 is easier to fit tightly on the patient's neck. For patients with a larger neck diameter, that is, a smaller neck surface curvature, the tubular airbag 1 is easy to fit on the patient's neck, so the gas pressure in the tubular airbag 1 can be appropriately increased.

[0042] Furthermore, if Figure 1-Figure 5 As shown, the tubular airbag 1 has a first tube section and a second tube section arranged in sequence along its length direction, the first end of the first tube section is an elliptical ring, the second end is a circular ring, the second tube section is a circular ring tube section, the second end of the first tube section has the same inner diameter and outer diameter as the second tube section, that is, the inner diameter of the second end of the first tube section is the same as the inner diameter of the second tube section, and the outer diameter of the second end of the first tube section is the same as the outer diameter of the second tube section. The inflation cavity of the first tube section is connected to the inflation cavity of the second tube section, and the inflation and discharge air pipe 13 and the oxygen air inlet are both arranged on the second tube section. The first tube section gradually transitions from the elliptical ring at the first end to the circular ring at the second end. The circular second tube section facilitates the arrangement of the inflation and discharge air pipe 13 and the oxygen air inlet.

[0043] Furthermore, if Figure 1-Figure 5 As shown, the inner diameter of the second tube segment is equal to the short axis length of the inner edge of the end surface of the first end of the first tube segment, and the outer diameter of the second tube segment is equal to the short axis length of the outer edge of the end surface of the first end of the first tube segment. Thus, the cross-sectional size of the second tube segment is smaller than the first end of the first tube segment, and the tube segment of the tubular airbag 1 away from the patient has a smaller volume, which facilitates the use of the tubular airbag 1.

[0044] Alternatively, if Figure 1-Figure 5 As shown, the tubular airbag 1 includes a tubular outer wall 15, a tubular inner wall 16, an annular bottom wall 17 and an elliptical annular bottom wall 18. The tubular inner wall 16 is arranged inside the tubular outer wall 15. The annular bottom wall 17 is arranged at the second end of the tubular airbag 1, the annular bottom wall 17 connects the tubular outer wall 15 and the tubular inner wall 16, and the annular bottom wall 17 surrounds the inlet and outlet airways. The elliptical annular bottom wall 18 is arranged at the first end of the tubular airbag 1, the elliptical annular bottom wall 18 connects the tubular outer wall 15 and the tubular inner wall 16. The tubular outer wall 15, the tubular inner wall 16, the annular bottom wall 17 and the elliptical annular bottom wall 18 are arranged to form a cavity of the tubular airbag 1, and the annular bottom wall 17 and the tubular outer wall 15, the annular bottom wall 17 and the tubular inner wall 16, the elliptical annular bottom wall 18 and the tubular outer wall 15, and the elliptical annular bottom wall 18 and the tubular inner wall 16 are all bonded and fixed. The bonding strip 2 is arranged on the elliptical annular bottom wall 18.

[0045] Optionally, the adhesive strip 2 is a hydrocolloid film, and one side of the adhesive strip 2 is bonded to the tubular airbag 1, and the other side is bonded to the neck skin of the patient. Hydrocolloid has the characteristics of low allergenicity, and most people are not prone to allergies after sticking it, and it is relatively friendly to the skin, and is relatively not prone to problems such as eczema, and can be used even if the skin is slightly damaged. In addition, the initial viscosity and lasting viscosity of the hydrocolloid are better, and it can generally be pasted for more than 7 days without contact with moisture. Hydrocolloid is a common material in the medical field, and hydrocolloid dressings and hydrocolloid band-aids have been widely used.

[0046] Furthermore, if Figure 1 and Figure 2 As shown, the adhesive strip 2 covers the oval annular bottom wall 18, so that the adhesive strip 2 can firmly adhere the tubular airbag 1 to the neck skin of the patient.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, the outer edge of the adhesive strip 2 is exposed outside the elliptical annular bottom wall 18, that is, the area of ​​the adhesive strip 2 is larger than the elliptical annular bottom wall 18, so that the adhesive strip 2 can be more closely attached to the patient's tracheostomy. Specifically, the adhesive strip 2 is also an elliptical ring, the long axis of the inner edge of the adhesive strip 2 is the same length as the long axis of the inner edge of the elliptical annular bottom wall 18, the short axis of the inner edge of the adhesive strip 2 is the same length as the short axis of the inner edge of the elliptical annular bottom wall 18, the long axis of the outer edge of the adhesive strip 2 is longer than the long axis of the outer edge of the elliptical annular bottom wall 18, and the short axis of the outer edge of the adhesive strip 2 is longer than the short axis of the outer edge of the elliptical annular bottom wall 18.

[0048] Optionally, the tubular airbag 1 is made of plastic or rubber. Compared with plastic, rubber has better elasticity and is easy to deform elastically. However, when the oxygen supply device for tracheostomy patients in this embodiment is used, it is necessary to keep the airway in and out connected. Therefore, during the inflation process, the tubular airbag 1 needs to maintain a tubular shape and should not undergo large elastic deformation. Therefore, in this embodiment, the tubular airbag 1 is preferably made of polyvinyl chloride. It can be understood by those skilled in the art that polyvinyl chloride, as a commonly used material in the medical field, can be used to make both hard products and soft products.

[0049] Alternatively, if Figure 1-Figure 5As shown, the oxygen supply device for tracheostomy patients provided in this embodiment also includes a soft baffle 3. The second end of the tubular airbag 1 is provided with a plurality of soft baffles 3. One end of the soft baffle 3 is fixed on the annular bottom wall 17 (that is, on the end surface of the second pipe section away from the first pipe section), and the other end extends in the direction of the center line of the inlet and outlet airway. The soft baffle 3 is arranged perpendicular to the center line of the inlet and outlet airway, and the plurality of soft baffles 3 are arranged in sequence along the circumference of the inlet and outlet airway. The soft baffle 3 can prevent larger foreign objects from falling into the inlet and outlet airway without hindering the inlet and outlet of the second inlet and outlet 12. In addition, the soft baffle 3 can also play a role in making the oxygen entering the inlet and outlet airway stay in the inlet and outlet airway for a short time to a certain extent. Due to the presence of the soft baffle 3, the oxygen entering the inlet and outlet airway through the oxygen inlet duct in the short time between two breaths of the patient will not flow out quickly through the second inlet and outlet 12, which is conducive to increasing the oxygen inhalation amount of the patient. The soft baffle 3 is bonded and fixed to the annular bottom wall 17. The soft baffle 3 is bonded and fixed to the annular bottom wall 17 so that each soft baffle 3 can have a large bonding area, ensuring that the soft baffle 3 is firmly bonded, reducing the risk of the soft baffle 3 falling off, and because the soft baffle 3 is located outside the inlet and outlet airways, even if the soft baffle 3 falls off, it will basically not reach the patient's tracheostomy through the inlet and outlet airways.

[0050] Furthermore, if Figure 4 and Figure 5 As shown, the soft baffle 3 is fan-shaped, and the sum of the central angles of the multiple soft baffles 3 at the second end of the tubular airbag 1 is 360°, so as to improve the shielding and protection effect of the soft baffle 3. In this embodiment, 8 soft baffles 3 are provided, and the central angle of each soft baffle 3 is 45°.

[0051] Furthermore, the soft baffle 3 is a lithium chloride sponge, which can smoothly discharge the carbon dioxide exhaled by the user and at the same time can maintain the temperature and humidity of the air in the inlet and outlet airways as much as possible, thereby improving the patient's breathing comfort.

[0052] Alternatively, if Figure 1-Figure 5 As shown, the oxygen supply device for tracheostomy patients provided in this embodiment also includes an oxygen inlet connector 4, which is inserted on the side wall of the tubular airbag 1, one end of the oxygen inlet connector 4 is exposed to the tubular airbag 1, and the other end extends into the inlet and outlet airways, the oxygen inlet duct is the inner cavity of the oxygen inlet connector 4, and the end of the oxygen inlet connector 4 exposed to the tubular airbag 1 is used to connect the oxygen tube, the oxygen tube mentioned here is connected to the oxygen humidification bottle, and the oxygen in the oxygen tube enters the oxygen inlet connector 4 after being humidified by the oxygen humidification bottle.

[0053] Alternatively, if Figure 1 and Figure 2As shown, the oxygen supply device for tracheostomy patients provided in this embodiment also includes an air intake adapter 5, which is used to connect the oxygen air intake connector 4 with the oxygen supply tube of the high-flow respiratory humidification therapy device. It can be understood by those skilled in the art that the diameter of the oxygen supply tube of the high-flow respiratory humidification therapy device is larger than the oxygen tube on the oxygen humidification bottle, so the oxygen air intake connector 4 that can be directly plugged with the oxygen tube on the oxygen humidification bottle requires an air intake adapter 5 to be plugged with the oxygen supply tube of the high-flow respiratory humidification therapy device.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
