Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a facial protection pad assisting a non-invasive breathing mask. Background Art

[0002] A non-invasive respiratory mask is a medical device that can be used for respiratory therapy, usually for the treatment of respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia, etc. Unlike traditional respiratory therapy methods, non-invasive respiratory masks do not require intubation, so they can reduce patient discomfort and complications and improve treatment effects. Non-invasive respiratory masks usually consist of a mask, a headband, and a connecting tube. The therapeutic effect of a non-invasive respiratory mask is related to the treatment time. Usually, patients need to use a non-invasive respiratory mask under the guidance of a doctor, for 6-8 hours a day, for several days or weeks in a row. In the process of using a non-invasive respiratory mask, patients need to pay attention to keeping the mask clean and replace the mask and headband regularly to ensure the treatment effect and patient comfort.

[0003] However, due to the airtightness requirements of non-invasive breathing masks, the pressure of the non-invasive breathing masks on the contact part of the face is relatively high. Long-term use will cause pressure sores on the patient's nose and face. In particular, the pressure in the nose is significantly higher than the pressure on the cheeks, which is particularly prone to forming pressure sores, which not only increases the pain of the patient, but also increases medical expenses. In addition, some patients who need mechanical ventilation also have a gastric tube in their nose. How to make the gastric tube pass through the mask without affecting the airtightness of the mask is a big problem.

[0004] Prior art CN219941007U utility model patent discloses a breathing mask, including a frame configured to form an airtight seal on the user's mouth and nose, and also includes a pad, which can form a seal between the mask and the user, and can also provide additional comfort for the user. The mask assembly may further include inserts for nose pads and forehead pads. The frame can be made of a variety of materials, including but not limited to silicone, plastic, rubber or polymers. Although the patent uses pads to relieve the pressure of the mask on the user's mouth and nose and to seal, these pads are directly connected to the breathing mask and cannot be replaced in time. Once soaked in liquid, it is impossible to achieve an effective sealing effect and reduce pressure sores. Replacing the breathing mask is costly. At the same time, when the user needs to insert a gastric tube, effective sealing cannot be achieved.

[0005] Prior art CN217138928U utility model patent discloses a non-invasive ventilator mask with a decompression dressing, including a mask body, a decompression auxiliary pad, a breathing tube and an adjustment component, wherein the decompression auxiliary pad is made of Mecon leather and has a good decompression buffering effect. Sealing rings are fixed on both sides of the decompression foam layer to increase the airtightness of the mask body when worn. The decompression auxiliary pad of this patent is directly set on the mask body, which is difficult to replace in time or has a high cost after being contaminated. At the same time, when the user needs to insert a gastric tube, the ventilator mask cannot effectively seal the inside of the mask. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a facial protection pad for assisting a non-invasive breathing mask, which can assist non-invasive breathing masks of various structures to achieve effective sealing when a gastric tube is inserted, reduce the occurrence of pressure sores in users of the non-invasive breathing mask, and is easy to replace.

[0007] The utility model provides a facial protection pad for assisting a non-invasive breathing mask, wherein the facial protection pad has the same shape as the bottom surface of the non-invasive breathing mask; the facial protection pad comprises a decompression foam layer and a sticky sealing layer from bottom to top, the decompression foam layer is made of Mepilex dressing, the width of the sticky sealing layer is at least 8 cm greater than the decompression foam layer and extends to both sides of the decompression foam layer; at least one gastric tube insertion incision is arranged at the position where the decompression foam layer contacts the cheek of the user when in use, the gastric tube insertion incision is L-shaped and passes through both sides of the decompression foam layer, and one end of the L-shaped incision extends to the bottom of the decompression foam layer; the thickness of the decompression foam layer is greater than the outer diameter of the gastric tube.

[0008] Preferably, a gastric tube insertion incision is respectively provided at the position where the decompression foam layer contacts the left cheek and the right cheek of the user when in use.

[0009] Preferably, the facial protection pad is in a ring shape that can cover the mouth and nose of the user, and the adhesive sealing layer extends at least 8 cm inside and outside the ring of the pressure relief foam layer respectively.

[0010] Preferably, the lower surface of the adhesive sealing layer is an adhesive surface.

[0011] Preferably, nose wing protection protrusions with a maximum thickness of more than 5 cm are respectively provided on both sides of the decompression foam layer that contacts the user's nose bridge when in use; the nose wing protection protrusions and the decompression foam layer are integrally formed.

[0012] Preferably, the nose wing protection protrusion is trapezoidal.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1) The facial protection pad provided by the utility model has an L-shaped gastric tube insertion incision in the decompression foam layer. The gastric tube can be inserted into the middle of the decompression foam layer from the bottom of the decompression foam layer along the L-shaped incision channel. The decompression foam layer is loose and elastic. Even if the gastric tube is inserted in the middle, the overall flatness of the facial protection pad will not be affected after being subjected to pressure, and effective air tightness can still be maintained.

[0015] 2) The facial protection pad provided by the utility model is an auxiliary device independent of the non-invasive breathing mask and can be used in conjunction with non-invasive breathing masks of various structures, especially those non-invasive breathing masks without an independent channel for the gastric tube. In addition, the facial protection pad is independent of the non-invasive breathing mask and is also easy to replace, reducing the risk of contamination.

[0025] The technical solution of the utility model will be described below. Obviously, the described embodiments are only part of the implementation methods of the present application, rather than all the implementation methods. It should be noted that based on these embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0026] like Figure 1-7 As shown, the utility model provides a facial protection pad for assisting a non-invasive breathing mask, which can provide sealing, buffering, prevention of pressure sores, and allowance for the passage of a gastric tube between the non-invasive breathing mask and the user. The facial protection pad has the same shape as the bottom surface of the non-invasive breathing mask, and usually needs to cover the user's mouth and nose to form a sealed space inside the non-invasive breathing mask. In some specific embodiments of the utility model, the facial protection pad is an irregular ring that can cover the user's mouth and nose.

[0027] like Figure 1 As shown, the facial protection pad of the utility model is composed of a pressure relief foam layer 100 and a sticky sealing layer 200 from bottom to top. The sticky sealing layer 200 covers the pressure relief foam layer 100, and the width of the sticky sealing layer 200 is at least 8 cm greater than the pressure relief foam layer and extends to both sides of the pressure relief foam layer. The part of the sticky sealing layer 200 extending to both sides can be pasted on the user's face for sealing and fixing. The part extending to both sides by at least 8 cm and pasting over a longer length ensures a tighter sealing effect. In some preferred embodiments of the utility model, the facial protection pad is an irregular ring that can cover the user's mouth and nose. The pressure relief foam layer 100 and the sticky sealing layer 200 are both ring-shaped, and the sticky sealing layer 200 extends at least 8 cm inside and outside the ring of the pressure relief foam layer 100 respectively; further preferably, the lower surface of the sticky sealing layer is a sticky surface.

[0028] Figure 2 Shown along Figure 1 In the cross-sectional view taken along the middle section line b, the pressure relief foam layer 100 is wrapped by the adhesive sealing layer 200 to form a seal when in use. The adhesive sealing layer 200 is attached to the skin to seal the pressure relief foam layer 100. Even if the pressure relief foam layer 100 contains other components (such as a gastric tube), it can be effectively sealed by the longer extensions on both sides of the adhesive sealing layer. At the same time, the adhesive sealing layer 200 can also cooperate with the non-invasive breathing mask to achieve sealing inside the ring when in use.

[0029] In the present invention, the decompression foam layer 100 is made of Mepilex dressing, which is a polyurethane foam dressing with good decompression and buffering effect, which can reduce the incidence of facial pressure sores in patients; it can absorb wound exudate, maintain a low oxygen, sterile, and moist environment for the wound, accelerate wound healing, and will not adhere to the wound or cause pain when replaced, which is particularly suitable for preventing or treating pressure injuries. In addition, the frequency of replacement of Mepilex dressing is low. If the wound has no exudate, it can be applied for up to 7 days, which is convenient to use.

[0030] In the present utility model, if Figure 3-5 As shown, at least one stomach tube insertion incision 400 is provided at the position where the decompression foam layer 100 contacts the cheek of the user when in use. The thickness of the decompression foam layer 100 is greater than the outer diameter of the stomach tube 500. The stomach tube insertion incision 400 is L-shaped and passes through both sides of the decompression foam layer (and the inner side surface and the outer side surface of the ring). One end of the L-shaped incision extends to the bottom of the decompression foam layer 100 to facilitate the entry of the stomach tube 500. The stomach tube 500 enters the other end of the L-shaped incision along the end and is placed in the middle of the decompression foam layer (such as Figure 4 shown). Figure 3 The sealing form after the gastric tube 500 enters the gastric tube insertion incision is shown. Since the decompression foam layer 100 is loose and elastic, the gastric tube 500 passes through the middle of the decompression foam layer 100 without affecting the flatness of the surface of the facial protection pad, and can still maintain air tightness. When subjected to pressure, the gastric tube 500 will not fall out of the L-shaped incision, that is, the decompression foam layer 100 is convenient for the gastric tube to pass through the middle and pass out without affecting air tightness. The adhesive sealing layer 200 can be used to fix the decompression foam layer 100 so that it does not slip off the face, while ensuring air tightness. Figure 5 The schematic diagram of the structure when the stomach tube insertion incision 400 is not inserted into the stomach tube 500 is shown. At this time, due to the covering and fixing of the external adhesive sealing layer 200, the air tightness inside and outside the ring will not be affected. In the utility model, the stomach tube insertion incision 400 is an L-shaped incision, including a connected transverse incision and a vertical incision, and the vertical incision extends to the bottom of the decompression foam layer 100 away from the end of the transverse incision, and the transverse incision is arranged in a horizontal direction. In some preferred embodiments of the utility model, a stomach tube insertion groove 410 is arranged at the end of the transverse incision away from the vertical incision, and the stomach tube insertion groove 410 is parallel to the transverse incision and is not connected to facilitate the insertion of the stomach tube 500. In some preferred embodiments of the utility model, a stomach tube insertion incision 400 is respectively arranged at the left cheek and right cheek of the user when the decompression foam layer 100 is in contact with the user when in use.

[0031] Considering that the nasal pressure is significantly higher than the cheek pressure when wearing a non-invasive breathing mask, and it is more likely to form pressure sores, in a preferred embodiment of the utility model, the two sides of the pressure relief foam layer 100 that contact the user's nose bridge when in use are respectively provided with nose wing protection protrusions 300 with a maximum thickness of more than 5 cm; the nose wing protection protrusions 300 and the pressure relief foam layer 100 are integrally formed, for example, both are made of Mepilex dressing. The integrally formed nose wing protection protrusions can disperse the pressure together with the pressure relief foam layer 100, and the pressure relief effect is better. Figure 6 The nose section of the face protection pad with nose wing protection protrusions is shown. The nose wing protection protrusions 300 with a maximum thickness of more than 5 cm on both sides of the nose are more conducive to relieving nasal pressure and reducing the occurrence of nasal pressure sores. In the present utility model, the maximum thickness of the nose wing protection protrusions 300 is preferably 6-8 cm. If it is less than 5 cm, it is not enough to effectively support the nose wing part. Figure 7 A specific structure of the nose protection protrusion 300 is shown. The nose protection protrusion is trapezoidal, which has a better force dispersion effect.

[0032] The face protection pad of the utility model can be designed according to masks of different models and different face shapes of patients, and can be designed in three sizes of large, medium and small to adapt to different face shapes and mask models and sizes, so as to be convenient to use and adapt.

[0033] The facial protection pad described in the utility model is used before the non-invasive breathing mask is worn. After the nose wing protection protrusion 300 is aligned with the patient, the viscosity of the two sides of the adhesive sealing layer 200 is used to attach it to the user's mouth and nose, and then the non-invasive breathing mask is worn. The facial protection pad can be replaced at any time during use, which is more clean and convenient. When the user also uses a gastric tube 500, the gastric tube 500 is first placed in the L-shaped gastric tube insertion incision, and then the nose wing protection protrusion 300 is aligned with the patient, and the viscosity of the two sides of the adhesive sealing layer 200 is used to attach it to the user's mouth and nose and both sides of the gastric tube 500, and then the non-invasive breathing mask is worn. The facial protection pad described in the utility model can be used to simultaneously use a gastric tube and a non-invasive breathing mask, ensuring that the non-invasive breathing mask can be used while the gastric tube is inserted, and the airtightness is good. The facial protection pad described in the utility model plays a decompression and wound protection effect when the non-invasive mask is worn, increases sealing and comfort, can be adjusted and adapted according to the face shape and mask, and is also suitable for mechanical ventilation of patients with gastric tubes.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
