Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a nasal catheter for preventing iatrogenic pressure sores. Background Art
[0002] Oxygen inhalation therapy is an important clinical treatment method. It supplies oxygen to patients, increases arterial oxygen partial pressure and blood oxygen saturation, increases blood oxygen content, corrects hypoxemia, improves tissue hypoxia caused by decreased blood oxygen, and maintains the functions of important organs such as the brain, heart, and kidneys. It can also reduce the increased workload of the heart and lungs caused by increased heart rate and breathing during hypoxia, relieve dyspnea, improve cardiopulmonary function, promote tissue metabolism, and maintain the body's vital activities.
[0003] Common oxygen therapy methods include nasal congestion and nasal cannula oxygenation, mask oxygenation, headgear oxygenation, continuous positive airway pressure oxygenation, and mechanical ventilation. Nasal congestion and nasal cannula oxygenation are the most basic oxygen therapy methods.
[0004] Nasal oxygen cannula oxygen delivery is widely used clinically due to its simplicity, practicality, comfort, lack of rebreathing, and ability to sit and eat. A disposable nasal oxygen cannula consists of a main cannula connected to two branch cannulas, each with a nasal inhalation tip. To administer oxygen, connect one end of the main cannula to the oxygen tank or the oxygen outlet of the pipeline, place the nasal inhalation tip in the nasal cavity, and then loop the two branches behind the ears, gently tightening the cannulas to secure them. Patients with respiratory diseases such as chronic obstructive pulmonary disease and cor pulmonale, or those with persistent conditions, require long-term oxygen therapy. However, prolonged use of a nasal cannula, which constantly contacts the same area, can also be difficult. Despite being made of silicone or polypropylene, nasal oxygen cannulas are still relatively rigid for the human body. After wearing a nasal oxygen cannula, it hangs behind the ear for a long time. The bony protuberance behind the ear lacks the protection of fat tissue and muscle wrapping, and the base layer is thin. Continuous pressure can lead to altered blood flow, causing tissue cells to degenerate and necrotize due to ischemia, hypoxia, and nutritional metabolic disorders. This can easily cause prolonged pressure on the auricle and localized facial skin, leading to pressure injuries, also known as iatrogenic pressure ulcers. This is particularly noticeable in patients with malnutrition, facial edema, emaciation, thin skin in the elderly, and paresthesia. To address this issue, a modified nasal cannula was designed to prevent pressure ulcers. Utility Model Content
[0005] The utility model aims to provide a nasal catheter for preventing iatrogenic pressure sores.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A nasal catheter for preventing iatrogenic pressure ulcers comprises a main tube connected to a branch tube, wherein the branch tubes are symmetrically arranged and fixed with nasal suction ends away from the ends of the main tube. The branch tubes are externally covered with a silicone film sleeve, and the silicone film sleeve is bonded with a spiral self-adhesive silicone dressing.
[0008] Furthermore, a plurality of protrusions are fixed on the inner wall of the silicone film sleeve, and the protrusions are integrated with the silicone film sleeve.
[0009] Furthermore, the branch tube is plug-connected to the nasal suction end.
[0010] Furthermore, the self-adhesive silicone dressing is spirally wound around the outside of the silicone film sleeve and then bonded to the silicone film sleeve.
[0011] To sum up, the beneficial technical effects of the utility model are as follows: a silicone film sleeve is set on the branch tube corresponding to the patient's ear and face position, and a self-adhesive silicone dressing is adhered to the outside of the silicone film sleeve, and the self-adhesive silicone dressing is used to contact the ear and face, thereby avoiding the occurrence of iatrogenic pressure sores. At the same time, the silicone film sleeve is adhered to the self-adhesive silicone dressing to avoid adhesion of the branch tube to the self-adhesive silicone dressing, which is convenient for replacing the self-adhesive silicone dressing and avoids the appearance of residual glue blocks on the branch tube after tearing off the self-adhesive silicone dressing.

[0017] The present invention will be described in further detail below with reference to the accompanying drawings.
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-3 The utility model provides a technical solution: a nasal catheter for preventing medical-induced pressure sores, comprising a main pipe 1, the main pipe 1 is connected to a branch pipe 2, the branch pipes 2 are symmetrically arranged, and the two branch pipes 2 are fixed with a nasal suction end 3 at the end away from the main pipe 1, and the outer part of the branch pipe 2 is covered with a silicone film sleeve 4, and the silicone film sleeve 4 is bonded with a spiral self-adhesive silicone dressing 5.
[0020] Among them, a number of protrusions 6 are fixed on the inner wall of the silicone film sleeve 4, and the protrusions 6 are integrated with the silicone film sleeve 4, thereby increasing the friction between the silicone film sleeve 4 and the branch pipe 2, thereby improving the stability of the silicone film sleeve 4 installed on the outside of the branch pipe 2.
[0021] In this embodiment, the branch tube 2 and the nasal suction end 3 are plug-connected to facilitate the removal of the silicone film sleeve 4 outside the branch tube 2.
[0022] At the same time, the self-adhesive silicone dressing 5 is spirally wound around the outside of the silicone film sleeve 4 and then bonded to the silicone film sleeve 4, thereby fully adapting to the curved shape of the branch pipe 2 and completely covering the outside of the branch pipe 2 with the self-adhesive silicone dressing 5.
[0023] The working principle of the present invention is as follows: the nasal suction end 3 and the branch tube 2 are plug-in connected. After the nasal suction end 3 is disassembled, a silicone film sleeve 4 is sleeved on the outside of the branch tube 2, and the sleeves are located at both ends of the nasal suction end 3, specifically, behind the patient's ear and face.
