Description

Technical Field

[0001] This utility model relates to the field of respiratory mask technology, specifically a pressure ulcer prevention respiratory mask. Background Technology

[0002] The breathing mask is suitable for adults to wear over the nose or mouth and is used in conjunction with a CPAP or bilevel breathing therapy device.

[0003] When a patient wears the mask, the constant pressure it applies to the face can impair blood circulation in certain areas, leading to pressure sores. Patients need to remove the mask periodically to prevent this. However, removing and re-putting the mask is cumbersome and inconvenient for patients. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant breathing mask to solve the problem of pressure sores easily caused by current breathing masks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure ulcer prevention breathing mask, comprising a mask body, wherein the rear wall of the mask body is provided with an air supply tube head, and the air pressure conversion mechanism includes a horizontal cylinder fixedly attached to the top of the mask body, a partition disposed in the middle of the inner cavity of the horizontal cylinder, sleeves fixedly fitted in the middle of the two end faces of the horizontal cylinder, push-pull rods respectively movably fitted in the sleeves, and piston discs fitted in the inner ends of the push-pull rods and slidably fitted to both sides of the middle of the inner cavity of the horizontal cylinder; a cover-shaped shell is fixedly located on the inner side of the rear wall of the inner cavity of the mask body, an outer bladder is fixedly fixed on the inner peripheral wall of the front end of the mask body, and an inner bladder is fixedly fixed on the outer peripheral wall of the front end of the cover-shaped shell; the inner cavities of the outer bladder and the inner bladder are respectively connected to the cavities on both sides of the partition through pipelines.

[0006] Preferably, a connecting air tube one is fixedly sleeved on the rear wall of the top of the outer bladder ring, and a connecting air tube two is fixedly sleeved on the rear wall of the top of the inner bladder ring. Connecting thin tubes that are sleeved and matched to the other ends of the connecting air tube one and the connecting air tube two are respectively provided at the bottom of the horizontal cylinder near the two sides of the partition.

[0007] Preferably, the inner end of the push-pull rod is rotatably sleeved with the center of the piston disc, and the push-pull rod and the sleeve are threaded together.

[0008] Preferably, an end cap is fixed to the outer end of the push-pull rod.

[0009] Preferably, the top and both sides of the front end of the mask body are provided with connecting rings for connecting straps.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model relates to an anti-pressure ulcer breathing mask, which allows for the inflation and deflation of the outer and inner bladder rings respectively through the push-pull operation of the piston disc using a push-pull rod. When inflated, the bladder rings expand to achieve a tight seal between the mask body and the patient's face; when deflated, they contract to relieve pressure on the patient's face. The two bladder rings can be easily and flexibly exchanged for inflation and deflation, preventing the same area of ​​the patient's face from being under pressure for extended periods, thereby preventing pressure ulcer formation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a pressure ulcer prevention breathing mask, including a mask body 1, an air delivery tube head 1.1 on the rear wall of the mask body 1, and connecting rings 1.2 for connecting straps on the top and sides of the front end of the mask body 1. Using the straps to tighten the mask body in three directions ensures that the front end of the mask body 1 better fits the patient's face. The air delivery tube head 1.1 is used to connect to oxygen tubing or other air delivery equipment.

[0022] A cover-shaped shell 1.3 is fixed to the inner wall of the rear cavity of the mask body 1, located on the inner side of its peripheral wall. An outer bladder ring 2 is fixed to the inner peripheral wall of the front end of the mask body 1, and an inner bladder ring 3 is fixed to the outer peripheral wall of the front end of the cover-shaped shell 1.3. The inner cavities of the outer bladder ring 2 and the inner bladder ring 3 are respectively connected to the cavities on both sides of the partition 4.2 through pipes. The outer bladder ring 2 and the inner bladder ring 3 are both made of thin, flexible, airtight, and elastic material. A connecting air tube 2.1 is fixedly sleeved on the rear wall of the top end of the outer bladder ring 2, and a connecting air tube 3.1 is fixedly sleeved on the rear wall of the top end of the inner bladder ring 3.

[0023] The air pressure conversion mechanism 4 includes a horizontal cylinder 4.1 fixedly attached to the top of the mask body 1, a partition 4.2 located in the middle of the inner cavity of the horizontal cylinder 4.1, sleeves 4.4 fixedly fitted in the middle of both ends of the horizontal cylinder 4.1, push-pull rods 4.5 movably fitted in the sleeves 4.4, and piston discs 4.6 fitted in the inner end of the push-pull rods 4.5 and slidably fitted to both sides of the middle of the inner cavity of the horizontal cylinder 4.1. Connecting thin tubes 4.3 are respectively provided at the bottom of the horizontal cylinder 4.1 near the partition 4.2, which are fitted to the other ends of connecting air pipe 2.1 and connecting air pipe 3.1. The inner end of the push-pull rod 4.5 is rotatably fitted to the center of the piston disc 4.6, and the push-pull rod 4.5 is threadedly fitted to the sleeve 4.4. An end cap 4.7 is fixed to the outer end of the push-pull rod 4.5.

[0024] In summary, during normal use, the piston disc 4.6 is pushed forward by the corresponding push-pull rod 4.5, causing the outer bladder 2 to be inflated, while the inner bladder 3 is deflated. The mask body 1 is then worn on the patient's face via the straps anchored to the connecting ring 1.2. The inflated outer bladder 2 fits tightly against the patient's face, ensuring the airtightness of the mask body 1's interior. To prevent pressure sores at the contact point of the outer bladder 2, the piston disc 4.6 is pushed forward periodically by the push-pull rod 4.5 on the other side, inflating the inner bladder 3. The inflated inner bladder 3 fits snugly against the patient's mouth and nose, ensuring normal air delivery. Then, the piston disc 4.6 is pulled outward by the push-pull rod 4.5 corresponding to the outer bladder 2, depressurizing the outer bladder 2 and relieving pressure on the patient's face. By alternating the inflation and depressurization of the outer capsule 2 and the inner capsule 3, pressure sores can be avoided from being caused by prolonged pressure on the same area of ​​the patient's face.

[0025] In addition, compared with using a conventional syringe for air extraction and inflation, the advantages of using this air pressure conversion mechanism 4 are: it reduces the frequent connection and disconnection of the tubing; and it saves the need for a valve sealing structure at the air bladder connection port.
