Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nasal cannula oxygen inhalation, and in particular relates to a nasal cannula oxygen inhalation mask with a pressure sore prevention function. Background Art
[0002] When patients use nasal cannula to inhale oxygen, they use a mist oxygen mask. The Chinese utility model patent application number is: CN2023219318468, which discloses an anti-strangulation medical oxygen mask, which solves the shortcomings of strangulation of the face and ears. However, in actual application, the parts where the oxygen mask contacts the facial skin may cause pressure sores, and the situation is more serious, not just the contact between the rope and the facial skin. Utility Model Content
[0003] The utility model aims to provide a nasal catheter oxygen inhalation mask with a pressure sore prevention function, which has the advantages of preventing pressure sores from being caused at the part in contact with the skin and facilitating wiping and moisturizing the lips of the patient with a cotton swab dipped in water.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A nasal catheter oxygen mask with an anti-pressure sore function comprises an anti-pressure sore face pad, an oxygen inhalation seat and a mask body; the anti-pressure sore face pad fits the face and is clamped between the face and the oxygen inhalation seat; the mask body and the oxygen inhalation seat are plugged and matched.
[0006] Working principles of the anti-pressure sore pad, oxygen seat and cover:
[0007] The function of the anti-pressure sore face pad is to prevent the mask from contacting the facial skin for a long time, which may cause strangulation marks and pressure sores. The oxygen inhalation seat and the mask are plugged in and installed. The staff can disassemble the mask as needed and use a cotton swab dipped in water to moisturize the patient's lips to avoid dryness caused by long-term oxygen inhalation. During installation, the anti-pressure sore face pad contacts the skin, while the mask is placed on the anti-pressure sore face pad and does not directly contact the skin.
[0008] Preferably, the anti-pressure sore face pad comprises an upper anti-pressure sore portion fitted with the brow and a lower anti-pressure sore portion fitted with the mouth and nose, and the upper anti-pressure sore portion and the lower anti-pressure sore portion are integrally formed.
[0009] The upper pressure sore prevention part mainly includes the forehead. Because the nasal cannula oxygen mask is generally fixed with fixing straps at both ends, the upper fixing strap is close to the forehead. The lower pressure sore prevention part is mainly placed on the patient's mouth and nose to protect the skin in the mouth and nose.
[0010] Preferably, the lower anti-pressure sore portion is provided with a gap for oxygen to pass through.
[0011] Since patients receiving oxygen generally have weak respiratory functions, the setting of the notch can facilitate the patients' spontaneous breathing and prevent the anti-pressure ulcer surface pad from blocking the mouth and nose breathing holes, thus causing breathing difficulties for the patients.
[0012] Preferably: an annular insertion part is provided at the upper end of the oxygen inhalation seat, and an annular slot adapted to the annular insertion part is provided at the lower end of the cover body. The annular insertion part and the annular slot are in plug-in fit, which is beneficial for the staff to disassemble and install in time.
[0013] Preferably: a silica gel sealing ring is provided at the lower end of the oxygen inhalation seat. The silica gel sealing ring has two functions. One is to prevent oxygen leakage, and the other is to play a role in pressure relief and increase the contact area between the lower end of the oxygen inhalation seat and the anti-pressure ulcer surface pad.
[0014] Preferably: a connecting block is provided at the upper end of the cover body, the free end of the connecting block is fixed to the fixed pressing block, and forehead straps are provided at both side ends of the fixed pressing block. If the connecting block and the fixed pressing block are not provided at the upper end of the cover body, on the one hand, the risk of the oxygen inhalation mask falling off is increased, and on the other hand, the position of the strap near the upper end of the forehead will be close to the eye part, affecting the line of sight.
[0015] Preferably: buckle seats are provided at both side ends of the cover body, and face straps are fixed on the buckle seats.
[0016] The installation of the buckle seats and the face straps is detachable, which can facilitate the staff to replace the face straps suitable for the face size and length of the patients.
[0017] Preferably: the fixed pressing block is closely attached to the side of the upper anti-pressure ulcer part facing away from the skin.
[0018] Preferably: a wire tube slot is provided at the upper end of the fixed pressing block.
[0019] Preferably: an oxygen inhalation tube is connected to the cover body, and a threaded joint is provided at the end of the oxygen inhalation tube facing away from the cover body.
[0020] Compared with the prior art, the beneficial effects of the present utility model are:
[0021] 1. An anti-pressure ulcer surface pad is arranged between the cover body and the facial skin, which can prevent the weight of the nasal catheter oxygen inhalation mask from pressing on the skin entirely, causing serious pressure ulcers.
[0022] 2. The oxygen inhalation seat and the cover body can be in plug-in fit, which is convenient for the staff to use a cotton swab dipped in clean water to replenish water for the patient's oral cavity and prevent dry mouth and nose caused by long-term oxygen inhalation.

Specific implementation mode
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0027] On the basis of the above description, this embodiment makes the following additional supplements from the actual application: The main body part of the nasal catheter oxygen inhalation mask with the function of preventing pressure sores includes:
[0028] Pressure sore prevention surface pad;
[0029] Oxygen inhalation seat 12;
[0030] Mask body 10.
[0031] Among them, the pressure sore prevention surface pad is made of non-woven fabric material, and a notch is reserved at the corresponding position of the mouth and nose to avoid affecting the patient's breathing.
[0032] The oxygen inhalation seat 12 and the mask body 10 are installed by insertion. When the staff needs to replenish water to the patient's mouth and nose, the mask body 10 can be opened, and clear water can be dipped to moisturize the patient's mouth and nose to avoid dry mouth and tongue.
[0033] At the same time, one end of the mask body 10 in contact with the pressure sore prevention surface pad is provided with a silicone rubber sealing ring 13. The function of the silicone rubber sealing ring 13 is to increase the contact area with the pressure sore prevention surface pad, thereby further reducing the pressure on the face. At the same time, the silicone rubber sealing ring 13 also plays a sealing role to avoid the loss of oxygen in the oxygen inhalation mask. Since some patients may use the method of atomized oxygen inhalation to administer drugs, if the sealing effect is not good, part of the drug will be seriously wasted.
[0034] For the fixing part of the nasal catheter oxygen mask: The front end of the mask body is connected with a fixed pressing block 3 through a connecting block 5. The fixed pressing block 3 is located corresponding to the forehead, and the side of the fixed pressing block 3 in contact with the forehead skin is arc-shaped. Both sides of the mask body are fixedly installed with face straps 6 through buckle seats 7. Then, near the forehead, it is fixed by a forehead strap 1, and near the mouth and nose, it is fixed by a face strap 6 to prevent falling off.
