Description

Technical Field

[0001] This utility model relates to the field of human necessities, and in particular to medical devices, especially a nasal cannula decompression and fixation protection belt device for a high-flow nasal oxygen therapy device. Background Technology

[0002] Nasal high-flow humidified oxygen therapy is now widely used in various clinical departments for a wide range of diseases. It provides constant temperature, humidity, and oxygen concentration, and through a nasal cannula, it enhances patient comfort and reduces anxiety, thus increasing its frequency of use and showing great promise. For patients with rheumatic and immune diseases involving pulmonary interstitial fibrosis, the disease progresses rapidly, increasing oxygen demand, making high-flow oxygen therapy the preferred method of oxygen therapy for patients in the progressive stage. In current technology, the two nasal connectors of the nasal cannula are inserted into the patient's two nasal cavities, and then a circular elastic band is used to fix the connectors to the nose. This elastic band wraps around the top of the head. Due to the high-frequency use of nasal high-flow oxygen therapy devices, the elastic band can easily cause pressure injuries to the face, ears, and back of the head, increasing the risk of device-related pressure injuries. Studies have reported that the incidence of device-related pressure injuries in adult hospitalized patients is 10.3%, and patients using medical devices are twice as likely to experience pressure injuries as those not using them.

[0003] The elastic band of the nasal cannula should be worn with appropriate tightness. Too tight a band will compress the skin of the nose, face, behind the ears, and back of the head; too loose a band will cause the nasal cannula to loosen, shift, or fall out, increasing the safety risks during oxygen therapy and affecting its effectiveness. The guidelines for nasal cannula use recommend adding a protective layer between the skin and the medical device, and securing the device with appropriate tape to prevent continuous movement and friction against the skin. Currently, protective dressings such as gauze, hydrocolloid dressings, and foam dressings are used clinically for pressure relief. These techniques have several shortcomings and require further improvement.

[0004] (1) Simply placing a pressure relief pad on the nose limits the pressure relief area and poses a risk of mechanical pressure injury to the face, behind the ears, and head.

[0005] (2) Adjusting the fixing position of the high-flow oxygen inhalation device to fix it to the head may cause the catheter to shake and shift, and condensate to flow back into the nose, which may lead to infection.

[0006] (3) Currently used protective dressings in clinical practice often contain gauze, which is rough and causes friction damage to facial skin, resulting in poor patient comfort and easy detachment. Hydrocolloid dressings and foam dressings are prone to curling or falling off when exposed to oily skin. Pulling on the patient's skin during dressing changes can cause secondary damage, and there is also a possibility of catheter displacement during dressing changes, leading to interruption of oxygen therapy. This significantly increases the difficulty of clinical nursing and also increases the economic burden on patients. In summary, existing nasal cannulas have shortcomings in terms of clinical safety, patient comfort and economy, nursing efficiency and quality. Utility Model Content

[0007] The purpose of this invention is to provide a nasal cannula decompression and fixation protection belt device for nasal high-flow oxygen therapy devices, which solves the technical problems of existing nasal cannula headbands having a large risk of instrument-induced pressure injury and the cannula being easily displaced due to insecure fixation.

[0008] This utility model provides a nasal cannula decompression and fixation protection strap device for a high-flow nasal oxygen therapy device, including a face protection strap and a head protection strap. The two ends of the face protection strap are connected into a ring by a first detachable structure. One end of the head protection strap is connected to one side of the face protection strap by a second detachable structure, and the other end of the head protection strap is connected to the other side of the face protection strap. A first anti-slip strip is provided in the middle of the front outer side of the face protection strap, and a second anti-slip strip is provided on the top inner side of the head protection strap. At least one first elastic band fixing structure is provided on both sides of the first anti-slip strip on the front outer side of the face protection strap, and a second elastic band fixing structure is provided on the outer side of the head protection strap.

[0009] Furthermore, the width of the front part of the face protection band increases from the middle to both sides.

[0010] Furthermore, the first detachable structure includes two first hook and loop fasteners, which are respectively fixed to both ends of the face protection band and are bonded to each other.

[0011] Furthermore, the second detachable structure includes two second Velcro straps, which are respectively fixed to the face protection strap and the head protection strap, and the two second Velcro straps are bonded to each other.

[0012] Furthermore, both the first and second anti-slip strips are silicone strips.

[0013] Furthermore, the number of the first elastic band fixing structures is two.

[0014] Furthermore, each of the first elastic band fixing structures includes two connecting straps, one end of which is connected to the upper edge of the face protection strap, and the other end of which is connected to the lower edge of the face protection strap. The other ends of the two connecting straps are attached by a third Velcro.

[0015] Furthermore, the second elastic band fixing structure is formed by winding a head protection band. The outer and inner edges of both sides of the head protection band are respectively provided with fourth hook and loop fasteners, and the two fourth hook and loop fasteners are glued to each other after the head protection band is wound.

[0016] Compared with existing technologies, the advantages of this invention are positive and significant. This invention isolates the nasal cannula from the patient's face, ears, and occipital region through a face and head protection strap, preventing direct pressure on the patient's skin, reducing the risk of pressure injury, improving patient comfort, and simplifying care. Furthermore, the first and second elastic band fixing structures prevent the elastic bands and nasal connector from moving freely, improving the stability of the nasal cannula and reducing the risk of oxygen therapy interruption due to device displacement.
