Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional headgear for a respiratory humidification therapy device and the respiratory humidification therapy device. Background Technology

[0002] High-flow oxygen through nasal cannula (HFNC) is a novel oxygen therapy technology. Currently, it is primarily used in hospital respiratory wards. It can rapidly increase blood oxygen saturation, effectively improve oxygenation, reduce the probability of invasive and non-invasive mechanical ventilation, and improve comfort by using heating and humidification devices to bring the gas to the most suitable temperature and humidity for the human body.

[0003] High-flow humidified respiratory therapy devices refer to therapeutic devices that continuously provide patients with high-flow (8-80 L / min) inhaled gas through a high-flow dedicated nasal cannula (e.g., nasal oxygen cannula) or other patient interfaces, allowing for adjustable and relatively constant oxygen concentration (21%–100%), temperature (31-37°C), and humidity.

[0004] In current technology, patients wear nasal cannulas for high-flow humidified oxygen therapy, which takes a relatively long time. When patients cough or turn over, the nasal cannulas are prone to dislodgement, preventing oxygen from being delivered to the nostrils and reducing the effectiveness of oxygen therapy.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a multifunctional headgear and a respiratory humidification therapy device for addressing the above-mentioned defects of the prior art. The aim is to solve the problem that the nasal oxygen delivery cannula is easy to fall off in the high-flow respiratory humidification therapy device in the prior art, resulting in low oxygen inhalation effectiveness.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] Please also refer to Figure 1 Figure - shows some preferred embodiments of a multifunctional headgear for a respiratory humidification therapy device.

[0050] like Figure 1 and Figure 2 As shown, the multi-functional headgear includes:

[0051] The transparent cover 11 is configured to fit the area around the nose and the cheek area;

[0052] Two flexible sleeves 12 are respectively connected to the upper left and upper right ends of the transparent cover 11;

[0053] Two binding straps 13 are respectively connected to the lower left and lower right ends of the transparent cover 11;

[0054] The transparent cover 11 is configured to cover the nasal oxygen delivery tube 21 in the respiratory humidification therapy device; the flexible sleeve 12 is configured to be fitted onto the tube hanging rope 22 in the respiratory humidification therapy device; and the two binding straps 13 are configured to be bound together in the back of the head area.

[0055] Specifically, the respiratory humidification therapy device includes a nasal cannula 21 and a cannula lanyard 22. The lanyard 22 is connected to the nasal cannula 21 and is worn on the patient's head. The nasal cannula 21 is used to supply heated and humidified oxygen to the patient's nose. The respiratory humidification therapy device can be an existing technology device or a high-flow humidification therapy device. The nasal cannula 21 is worn at the base of the nose, and the lanyard 22 is looped around the patient's head from above the ear to the back of the head for proper wearing.

[0056] The nasal cannula 21 is used in conjunction with a multi-functional headgear. A flexible sleeve 12 is fitted over the cannula lanyard 22; for example, the lanyard 22 can be passed through the flexible sleeve 12. The nasal cannula 21 is located inside the transparent cover 11, and the flexible sleeve 12 is blocked and limited by the nasal cannula 21, preventing it from passing through. Then, the cannula lanyard 22 and nasal cannula 21 are put on. Finally, the two binding straps 13 are wrapped around the back of the head, passing under either the left or right ear, and tied together. The transparent cover 11 covers the nasal cannula 21. Due to the restriction of the flexible sleeve 12 and binding straps 13, the transparent cover 11 helps to secure the nasal cannula 21, reducing the risk of it falling off. In addition, the transparent cover 11 can fit the area around the nose and cheeks, forming a more enclosed space around the nose. Even if the nasal oxygen delivery tube 21 is removed from the nostril, the nasal oxygen delivery tube 21 will introduce oxygen into this more enclosed space, and the patient can still inhale enough oxygen, further improving the effectiveness of oxygen inhalation.

[0057] In addition, the catheter lanyard 22 needs to be tied tightly to properly secure the nasal oxygen delivery catheter 21, and the lanyard 22 may put pressure on the skin of the ears, cheeks, and other areas. The flexible sleeve 12 extends above the ears and separates the skin of the ears, cheeks, and other areas from the catheter lanyard 22, which helps to reduce the pressure of the catheter lanyard 22 on the skin of the ears, cheeks, and other areas.

[0058] When using the transparent cover 11, medical staff can easily observe the status of the nasal oxygen delivery tube 21 inside the transparent cover 11. If the nasal oxygen delivery tube 21 is not correctly inserted into the nostril, the binding strap 13 can be untied, the position of the nasal oxygen delivery tube 21 can be adjusted, and then the binding strap 13 can be tied back.

[0059] In a preferred embodiment of this utility model, please also refer to... Figures 2-3 The flexible sleeve 12 is a cylindrical flexible sleeve.

[0060] Specifically, the flexible sleeve 12 can be a cylindrical flexible sleeve. The cylindrical sleeve can change direction, which also makes it convenient for the guide rope 22 to pass through the cylindrical flexible sleeve hole.

[0061] In a preferred embodiment of the present invention, the flexible sleeve 12 is a foam dressing flexible sleeve.

[0062] Specifically, the flexible foam dressing sleeve 12 can be deformed under pressure, and the flexible foam dressing sleeve will not damage the skin when it comes into contact with the skin.

[0063] In a preferred embodiment of this utility model, please also refer to... Figure 2 , Figure 4 as well as Figure 5 The multifunctional headgear also includes:

[0064] Flexible earplug 14 is configured to be inserted into the ear canal.

[0065] Specifically, the flexible earplug 14 can be inserted into the patient's ear canal to reduce the impact of the noise from the respiratory humidification therapy device on the patient, allowing the patient to receive high-flow humidified oxygen therapy while sleeping without affecting sleep quality.

[0066] In a preferred embodiment of this utility model, please also refer to... Figures 2-4 The cylindrical flexible sleeve has a hole through which the flexible earplug 14 can be inserted.

[0067] Specifically, the cylindrical flexible sleeve's hole can also be used to insert the flexible earplug 14. After the flexible earplug 14 is used up, it can be inserted into the cylindrical flexible sleeve's hole for the next use, reducing the chance of the flexible earplug 14 being misplaced or lost.

[0068] In a preferred embodiment of this utility model, the transparent cover 11 is a flexible transparent cover.

[0069] Specifically, the flexible transparent cover can deform to better fit the area around the nose and cheeks.

[0070] In a preferred embodiment of this utility model, please also refer to... Figures 2-3 The transparent cover 11 is provided with a nose bridge strip 111.

[0071] Specifically, the nose bridge strip 111 is a rigid nose bridge strip that can be bent and shaped, for example, bent into a shape that fits the nose bridge, which makes it easier for the transparent cover 11 to fit the area around the nose and the cheek area.

[0072] like Figure 1 and Figure 2 As shown, based on any of the above embodiments of the multifunctional headgear, this utility model also provides a respiratory humidification therapy device, including:

[0082] Bellows 213 is connected to the air inlet;

[0083] The fixing clip 214 is configured to fix the bellows 213 to the conduit hanging rope 22.

[0084] Specifically, the nasal base compartment 211 can be made of a flexible, skin-friendly material, such as rubber or silicone. Using a flexible, skin-friendly material reduces the risk of the nasal base compartment 211 damaging the nose. The outlet tube is inserted into the nostril, and heated and humidified oxygen within the corrugated tube 213 is delivered to the inlet and then enters the patient's nostril through the outlet tube. The connector 212 can be detachably connected to the nasal base compartment 211, making the nasal base compartment 211 and the corrugated tube 213 replaceable accessories, while the connector 212 and the catheter hanging rope 22 can be reused.
