Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a medical high-flow nasal catheter decompression protective pad. Background Art

[0002] High-flow nasal oxygen therapy is an effective means of respiratory support. It can provide stable, adjustable oxygen concentration inhaled gas, and at the same time has good airway warming and humidification functions, which helps to flush airway dead space to improve ventilation efficiency and produce a certain positive end-expiratory pressure effect. This therapy is becoming more and more widely used in clinical practice due to its simplicity and comfort.

[0003] During nasal high-flow oxygen therapy, a high-flow gas mixture of air and oxygen with a certain oxygen concentration needs to be delivered to the patient through a nasal cannula. However, since the nasal cannula needs to be worn for a long time, the patient's nose and lips are prone to pressure injuries. To solve this problem, protective measures are usually adopted clinically to reduce the pressure of the nasal cannula on the skin, such as applying moisturizers such as vaseline to protect the skin, using hydrocolloid dressings to cover the pressure area, or directly using paper towels or soft cotton strips as pads. Although the method is simple to operate, the improvement effect is not good and the purpose of decompression is not achieved. Pressure injuries still occur on the skin in this area, and the aesthetics are poor, affecting the patient's own image. In particular, when the hydrocolloid dressing is torn off, further mechanical damage will be caused to the skin, thereby increasing the patient's discomfort.

[0004] Therefore, a medical high-flow nasal cannula pressure relief protective pad is proposed. Utility Model Content

[0005] In order to overcome the problem that the nasal cannula easily compresses the nasal labia and causes pressure damage to the nasal labia during current clinical high-flow nasal oxygen therapy, the utility model provides a medical high-flow nasal cannula pressure-reducing protective pad.

[0006] To solve the above problems, the present invention adopts the following technical solution: a medical high-flow nasal catheter decompression protective pad, including a dressing, a fixing belt, an anti-slip belt, an absorbent layer, an outer covering adhesive layer and a clamping plate. The two ends of the dressing are provided with fixing belts, and an anti-slip belt is provided between the fixing belts. The dressing itself is composed of an absorbent layer, an outer covering layer and an adhesive layer. These three layers are arranged in sequence and together constitute the main structure of the decompression protective pad. Two sets of clamping plates are provided in the middle position of the dressing for fixing the nasal plug of the nasal catheter.

[0007] In one embodiment, the fixing belt is designed to be elastic and retractable.

[0008] In one embodiment, the clamping plate is designed to be arc-shaped.

[0009] In one embodiment, it also includes a sub-patch, a limiting belt and a mother patch. The lower edges of both ends of the dressing are provided with sub-patch, and the upper edges of both ends of the dressing are provided with limiting belts for fixing the nasal catheter. The surface of the limiting belt is provided with a mother patch bonded to the sub-patch.

[0010] In one embodiment, an anti-slip pad is further included, and the side of the limiting belt that contacts the nasal catheter is provided with an anti-slip pad.

[0011] In one embodiment, a rubber plate and a silicone rod are further included. The rubber plate is provided below the middle position of the dressing, and the rubber plate is provided with symmetrically distributed silicone rods. The rubber plate and the silicone rods are used together to support and hold up the nasal congestion.

[0012] In one embodiment, a protective sleeve is further included, and the surface of the silicone rod is covered with the protective sleeve.

[0013] Compared with the existing technology, the utility model has the following technical effects: 1. This product is integrated into a decompression protective pad dedicated to medical high-flow nasal catheters. By using a dressing to separate the nasal catheter from the skin, the pressure of the nasal catheter on the nasal septum and the surrounding skin is reduced, thereby effectively reducing the occurrence of pressure injuries. In addition, the head-mounted fixed design of this product takes into account simplicity, patient comfort and aesthetics, and ensures that patients can wear it conveniently during the entire treatment process while reducing the impact on daily activities.

[0014] 2. The design of rubber plates and silicone rods provides effective support for the nasal plug part of the nasal cannula, preventing the nasal cannula from sagging due to gravity, further reducing the pressure in the nose, and ensuring the stable position of the nasal cannula.
