Description

Technical Field

[0001] The utility model relates to the technical field of medical care appliances, and in particular to a nasal tube protective pad for a high-flow respiratory humidification therapeutic apparatus, which is used to prevent pressure sores from forming on the facial skin of a patient and to avoid burns to the nasal mucosa and the skin near the nasal cavity. Background Art

[0002] High-flow respiratory humidification therapy device refers to a treatment method that continuously provides patients with high-flow (8~80L / min) inhaled gas with adjustable and relatively constant oxygen concentration (21%~100%), temperature (31-37℃) and humidity through a high-flow dedicated nasal plug or other patient interface. High-flow respiratory humidification therapy device is a new type of oxygen therapy device. Its safety and efficacy are gradually recognized. Compared with ordinary oxygen therapy, it has a better effect on improving oxygenation; compared with non-invasive ventilators, its significant advantages lie in comfort, tolerance and compliance. For patients with mild to moderate hypoxemia, high-flow respiratory humidification therapy device can be the first choice for treatment.

[0003] In clinical care, a high-flow nasal oxygen cannula is required when a high-flow respiratory humidification therapy device is used to supply oxygen to patients. The high-flow nasal oxygen cannula generally includes a main tube, a nasal tube, a fixing and a strap. The fixing is generally made of hard material and is used to shape and fix the main tube and the nasal tube. The two ends of the fixing are respectively connected to the strap and are fixed by the strap around the cheek. The strap has a certain elasticity, and at the same time, the strap usually has a certain degree of tension to prevent the nasal tube from falling out of the nasal cavity. Therefore, when the patient wears a high-flow nasal oxygen cannula for a long time, the fixing and the connection between the fixing and the strap will continue to compress the patient's face, making the patient's face prone to pressure sores. In addition, when the fixing is in contact with the patient's face, it will produce a certain amount of friction with the patient's skin, which will cause the patient's skin to be worn out. At the same time, since the skin of elderly patients is relatively thin, and the gas temperature in the high-flow nasal oxygen cannula of existing equipment can only be adjusted to 31°C at its lowest, when elderly patients use high-flow nasal oxygen cannula for oxygen therapy for a long time, the nasal mucosa and the skin near the nasal cavity that are in contact with the nasal cannula for a long time are prone to burns, causing unnecessary physical harm to the patients. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that when a patient wears and uses a high-flow nasal oxygen cannula for a long time, the fixing part and the connection between the fixing part and the strap will continue to compress the patient's face, which may easily cause pressure sores on the patient's face. At the same time, the gas temperature in the nasal cannula is relatively high, and long-term use may easily cause burns to the nasal mucosa and the skin near the nasal cavity of elderly patients. Thus, a nasal cannula protective pad for a high-flow respiratory humidification therapy device is provided, which is used to prevent the formation of pressure sores on the patient's facial skin and avoid burns on the nasal mucosa and the skin near the nasal cavity.

[0005] To this end, the utility model provides a nasal tube protective pad for a high-flow respiratory humidification therapeutic device, comprising:

[0006] The pad comprises a long strip pad body, and the two side ends of the pad body extending in the length direction are bent downward to form an arc-shaped portion suitable for fitting on the human face;

[0007] Two protective sleeves are arranged in parallel and opposite to each other, and include a hollow sleeve, and the sleeve is detachably installed above the cushion body;

[0008] When the pad body is placed snugly on the human face, the nasal tube can pass through the sleeve and enter the nasal cavity, and the sleeve can separate the nasal tube from the human facial skin.

[0009] Furthermore, the pad also includes:

[0010] A vertical plate, one end of which is fixedly connected to the cushion body, and the other end of which extends vertically away from the cushion body;

[0011] Two plug-in posts are arranged oppositely on two sides of the other end of the vertical plate;

[0012] The sheath further comprises:

[0013] The plug-in cylinder has an outer wall fixedly connected to the outer wall of the sleeve and has a cavity formed inside for the plug-in column to be inserted and installed;

[0014] The sleeve is rotatably mounted on the plug-in column through the plug-in tube.

[0015] Furthermore, an anti-slip structure is provided on the outside of the plug-in column and / or the inside of the plug-in tube.

[0016] Furthermore, the sheath further comprises:

[0017] The heat-insulating tube is fixedly connected to the sleeve and is used for being sleeved on the nasal tube to separate the nasal tube from the mucosa inside the nasal cavity.

[0018] Furthermore, the wall of the thermal insulation tube is a thin film structure.

[0019] Furthermore, the inner side wall of the sleeve is provided with an anti-slip structure.

[0020] Furthermore, a notch for avoiding the nose is formed on the pad body at a position corresponding to the sleeve.

[0021] Furthermore, the pad also includes: a stopper, which is arranged on the pad body at a side away from the notch and is a strip-shaped protrusion formed on the upper surface of the pad body;

[0022] A fixing space for engaging a fixing member is formed between the stopper and the vertical plate.

[0023] Furthermore, the pad body and the sleeve are made of silicone.

[0024] The technical solution provided by the utility model has the following advantages:

[0025] The utility model discloses a nasal tube protective pad for a high-flow respiratory humidification therapy device, comprising a protective pad and a protective sheath; wherein the protective pad comprises an elongated pad body, and both side ends of the pad body extending in the length direction are bent downward to form an arc-shaped portion suitable for fitting on the human face; the protective sheath is provided in two pieces, which are arranged in parallel and opposite to each other, and comprise a hollow sleeve, and the sleeve is detachably mounted above the pad body; when the pad body is fitted on the human face, the nasal tube can pass through the sleeve to enter the nasal cavity, and the sleeve can separate the nasal tube from the human facial skin.

[0026] When using the nasal tube protective pad for a high-flow respiratory humidification therapy device of this embodiment, the pad body is placed between the patient's facial skin and the fixing piece, thereby preventing the fixing piece from directly pressing and rubbing the patient's facial skin; the arc-shaped portion is located at the connection between the fixing piece and the strap, thereby preventing the connection from causing pressure and friction on the patient's facial skin; the sleeve is arranged on the outside of the nasal tube, thereby preventing the nasal tube from contacting the skin around the patient's nasal cavity and avoiding burns to the skin.
