Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen inhalation devices, specifically a temperature and humidity regulated oxygen inhalation device suitable for tracheostomy patients. Background Technology
[0002] Tracheotomy is an emergency surgical procedure that involves cutting open the anterior wall of the trachea in the neck and inserting a tracheostomy tube to create an artificial airway.
[0003] To provide oxygen support to patients, hospitals are equipped with oxygen therapy devices. These devices typically include an oxygen source (such as an oxygen concentrator), a humidification device (such as a humidification bottle), oxygen tubing, and connecting components. In actual installation, the oxygen source is usually located away from the wards, and tubing is laid throughout the hospital area to deliver oxygen to the wards. An interface is also installed at the end of each bed. When a tracheostomized patient is transferred to a ward, the oxygen tubing is connected to the oxygen interface and the endotracheal tube at the incision site.
[0004] Because of the long-distance oxygen delivery, the oxygen temperature is low, especially in cold seasons. Additionally, the oxygen source provides relatively dry oxygen. Furthermore, tracheostomy disrupts the integrity of the upper respiratory tract, depriving it of the natural defense mechanisms of structures like the nasal cavity and oral cavity. When administering oxygen to patients via tracheostomy, the upper respiratory tract cannot warm, humidify, or filter the inhaled air; instead, external air directly enters the lower respiratory tract through the tracheostomy tube. This untreated air irritates the airway mucosa, leading to dryness, weakened ciliary movement, and increased risk of infection.
[0005] Although common humidification bottle oxygen inhalation methods can humidify oxygen to a certain extent, they cannot effectively regulate temperature. In cold seasons or dry environments, even oxygen that has passed through a humidification bottle may still be too cold and lack sufficient humidity, causing airway discomfort for patients and exacerbating airway mucosal damage.

[0032] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:
[0033] Example 1
[0034] like Figure 1 As shown, to avoid the low temperature of oxygen inhaled by tracheostomy patients, this embodiment provides a new oxygen inhalation device. The oxygen inhalation device includes a humidification bottle 1, a heater, etc. The inlet end of the heater is connected to the oxygen interface, and the outlet end is connected to the inlet end of the humidification bottle 1. Therefore, the oxygen entering the heater is heated under the action of the heater, increasing the temperature of the oxygen. The heated oxygen flows to the humidification bottle 1 and comes into contact with the liquid (such as distilled water) in the humidification bottle 1, increasing the humidity of the oxygen. Then, the heated and humidified oxygen can flow into the tracheostomy patient, avoiding discomfort caused by low oxygen temperature and high dryness.
[0035] like Figure 4 , Figure 5As shown, to achieve oxygen heating, the heating device includes a tube 4, a heating rod 5, and a gas guiding device 6. The tube 4 is designed with two through-holes, and an outlet pipe 42 is provided on the side wall of the tube 4. The heating rod 5 and the gas guiding device 6 are both located inside the tube 4, and the gas guiding device 6 covers the heating element of the heating rod 5, while isolating the tube 4 to form two spaces, inside and outside. The ends of the heating rod 5 and the gas guiding device 6 that are far apart from each other are detachable and sealed at both ends of the tube 4, thus forming a channel for gas flow. When the heating device is connected to the oxygen interface, oxygen flows from the end of the gas guiding device 6 into the space located inside the gas guiding device 6 and comes into contact with the heating rod 5, thereby increasing the temperature of the oxygen under the action of the heating rod 5. The heated oxygen flows from the inner space to the outer space of the gas guiding device 6, and then exits the tube 4 from the outlet pipe 42, and then flows into the humidification bottle 1.
[0036] like Figure 6 , Figure 7 , Figure 8 As shown, in order to form a sealed space between the heating rod 5 and the tube body 4 under the action of the heating rod 5 and the air guiding device 6, threaded structures 41 are provided at both ends of the inner wall of the tube body 4. A first sealing cap 51 is fitted onto the end of the heating rod 5, and the first sealing cap 51 is threadedly inserted into the end of the tube body 4. The heating element of the heating rod 5 is located on the central axis of the tube body 4. The air guiding device 6 includes a second sealing cap 63, which is threadedly inserted into the other end of the tube body 4. A sealing ring is provided on the contact surface between the sealing cap and the tube body 4, thereby achieving a sealed connection between the sealing cap and the tube body 4.
[0037] like Figure 5 As shown, to create two spaces, inner and outer, the gas guiding device 6 includes a gas guiding pipe 61. The gas guiding pipe 61 is mounted on the second sealing cover 63 and extends into the tube body 4. The outer diameter of the gas guiding pipe 61 is smaller than the inner diameter of the tube body 4, while the inner diameter is larger than the size of the heating rod 5. Therefore, when the heating rod 5 is positioned on the central axis of the tube body 4, the gas guiding pipe 61 covers the heating element of the heating rod 5. Additionally, a second air inlet pipe 64 is provided on the side of the second sealing cover 63 away from the first sealing cover 51. The second air inlet pipe 64 communicates with the gas guiding pipe 61 and is connected to an oxygen interface. Therefore, oxygen enters the space inside the gas guiding pipe 61 through the second air inlet pipe 64, ensuring sufficient contact between the oxygen and the heating rod 5 and increasing its temperature. When the oxygen flows to the end of the gas guiding pipe 61 near the first sealing cover 51, it overflows into the inner space, flowing into the outer space. Under thermal radiation, the temperature of the outer space is also higher, achieving oxygen insulation and reducing heat waste. The oxygen gathered in the outer space flows to the end away from the first sealing cap 51 and is then output from the outlet pipe 42 into the humidification bottle 1.
[0038] like Figure 1As shown, the top cover of the humidification bottle 1 is equipped with an exhaust valve 11 and a first air inlet pipe 12. The first air inlet pipe 12 penetrates the top cover and extends into the humidification bottle 1 at its bottom, and is located near the bottom of the humidification bottle 1. Because the exhaust pipe 42 is connected to the first air inlet pipe 12 through a pipe, the oxygen from the output heating device accumulates at the top of the humidification bottle 1 after contacting the liquid inside the humidification bottle 1, increasing the oxygen humidity. Then, the temperature- and humidity-controlled oxygen is output from the exhaust valve 11 and flows to the patient's tracheostomy site.
[0039] like Figure 8 As shown, to ensure the stable installation of the gas guide tube 61 within the tube body 4, a first annular plate 52 and a second annular plate 53 are provided on the end face of the first sealing cover 51 near the second sealing cover 63. The end of the gas guide tube 61 is sealed and inserted into the space formed by the first annular plate 52 and the second annular plate 53. Therefore, the stability of the gas guide tube 61 is enhanced by the cooperation of the annular plate and the sealing cover. To avoid affecting the flow of gas, multiple air holes 62 are provided at the end of the gas guide tube 61 near the first sealing cover 51. The air holes 62 connect the inner and outer spaces of the gas guide tube 61, and the air holes 62 are located on the side of the annular plate. To filter impurities in the oxygen, a filter element can be provided on the inner side of the gas guide tube 61.
[0040] The heating rod 5 described above is a publicly available device, which will be briefly introduced here. The heating rod 5 includes a heating element, insulating material, a temperature controller, a housing, and a temperature sensor. Common heating element materials include nickel-chromium alloy wire and ceramic heating elements, which achieve heating through Joule heating generated when an electric current passes through them. The insulating material is used to enclose the heating element, preventing current leakage and ensuring safe use; common insulating materials include magnesium oxide powder and ceramics. The temperature controller controls the operating temperature of the heating rod, ensuring that the temperature remains within the set range. For example, after heating to a certain temperature, the temperature controller automatically cuts off the power. The temperature sensor monitors the temperature in real time and feeds the temperature signal back to the temperature controller for precise temperature control.
[0041] Example 2
[0042] like Figure 1 As shown, based on Example 1, in order to avoid reduced airflow, reduce alveolar collapse, and reduce the incidence of lower respiratory tract infection in endotracheal intubation patients, a Venturi tube 2 is also provided. Both ends of the Venturi tube 2 are provided with gas tubes 21, which are threadedly connected to the Venturi tube 2. One gas tube 21 is connected to the outlet valve 11 of the humidification bottle 1 through a pipe, and the other gas tube 21 is connected to the endotracheal tube of the tracheostomy.
[0043] Example 3
[0044] like Figure 1 , Figure 2 , Figure 3As shown, based on Embodiment 1 or 2, in order to place the humidification bottle 1, the Venturi tube 2 and the heating device relatively stably, a connecting frame 3 is also provided. The connecting frame 3 includes a first clamp 31, a second clamp 32 and a third clamp 33. The first clamp 31 is sleeved on the tube body 4, the second clamp 32 is sleeved on the Venturi tube 2 and the third clamp 33 is sleeved on the humidification bottle 1. Therefore, under the action of the connecting frame 3, the humidification bottle 1, the Venturi tube 2 and the heating device are relatively stably connected.
[0045] like Figure 2 , Figure 3 As shown, to allow for the disassembly of the humidification bottle 1, Venturi tube 2, and heating device as needed, the first clamp 31 includes two symmetrical first arc plates 35, the second clamp 32 includes two symmetrical second arc plates 36, and the third clamp 33 includes two symmetrical third arc plates 37. The first arc plates 35, second arc plates 36, and third arc plates 37 on the same side are connected by a connecting plate 34. The two connecting plates 34 are connected by bolts. Therefore, when the two connecting plates 34 are close to each other, the two opposing first arc plates 35, second arc plates 36, and third arc plates 37 move closer together and press against the heating device, Venturi tube 2, and humidification bottle 1, ensuring their stable installation relative to the connecting frame 3. When it is necessary to disassemble the humidification bottle 1, Venturi tube 2, and heating device, simply rotate the bolts to move the connecting plate 34 away from the opposing first arc plates 35, second arc plates 36, and third arc plates 37.
[0046] like Figure 9 As shown, to ensure the stable placement of the humidification bottle 1, venturi tube 2, and heating device on the support frame 3, a support plate 38 is vertically installed on the side of the connecting plate 34, and a snap-fit plate 381 is fixedly installed at the end of the support plate 38. A fixing seat 39 is provided on the side of the support plate 38, and the fixing seat 39 has an inlet / outlet groove 392 and a snap-fit groove 391. The inlet / outlet groove 392 communicates with the end of the snap-fit groove 391, and the snap-fit plate 381 can pass through the inlet / outlet groove 392 and be installed within the snap-fit groove 391. When the fixing seat 39 is stably installed, it can support the support frame 3 for stable placement, thus facilitating the use of the device for oxygen delivery.
[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
