Description

A protective pad for a non-invasive ventilator

technical field

The utility model relates to an isolation pad used in the use of a non-invasive ventilator, in particular to a protective pad for a non-invasive ventilator.

Background technique

Non-invasive ventilator has been widely used clinically due to its advantages of non-invasiveness and simplicity. With the further expansion of the scope of indications and the affirmation of the therapeutic effect, the number of non-invasive ventilator home users is gradually increasing, and in chronic obstructive pulmonary disease Its use has been supported by a large amount of clinical evidence. The non-invasive ventilator is usually on for 4-24 hours a day, and clinically it is usually 8-24 hours a day. Due to wearing the machine for a long time, the facial skin that has been in contact with the nasal mask for a long time is under pressure for a long time, and the silicone pad has poor air permeability, etc., which often lead to pressure sores on the face of the wearer. It has been reported in the literature that the rate of facial skin damage is as high as 70% if the continuous ventilation time is more than 48 hours, and the compression time is long, the patients are poor in nutrition, and are more prone to compression damage when accompanied by facial edema. Most users of non-invasive ventilators in the respiratory department are the elderly. Due to loose facial skin and poor nutrition, the incidence of pressure sores is high in the elderly.

Utility model content

The purpose of this utility model is to provide a protective pad for a non-invasive ventilator, which can better fit the patient's face and effectively prevent or treat nasal and facial pressure sores caused by wearing a non-invasive ventilator nasal mask for a long time.

The purpose of this utility model is achieved through the following technical solutions:

A protective pad for a non-invasive ventilator includes a nose bridge pad, which extends outwards from the lower part of the nose bridge pad to form two extension strips. The nasal mask of the non-invasive ventilator is in direct contact with the bridge of the nose, and forms a contact part connected with the bridge of the nose on the face. By setting the bridge of the nose pad, two extension strips are set on the bridge of the nose pad. It is connected and located directly under the nasal mask, so that there is a layer of protective pad between the nasal mask and the patient's face, which effectively protects the patient's face and nose bridge, and avoids the occurrence of pressure sores.

The corners of the nose bridge pad and the extension strip are arc-shaped. As a further improvement of the utility model, by setting the corners of the nose bridge pad and the extension strip into arc shapes, the nose bridge pad and the extension strip can fit the patient's face and nose bridge while avoiding damage due to slight shaking or tearing. fall off.

Both the nose bridge pad and the extension strip are made of composite layer structure materials. Furthermore, the nose bridge pad and the extension strip made of materials with a composite layer structure have more functions, and the combined functions make the utility model have more advantages.

The materials of the composite layer structure are, from bottom to top, a soft polysilicone layer, a foam pad absorption layer, and a waterproof and breathable layer. Furthermore, the use of a soft silicone layer as the bottom layer in contact with the patient's face and bridge of the nose has the advantage of not sticking to the wound, even if the exudate has begun to dry, it can be gently and safely pasted on the skin, and it does not need to be removed. Cause epidermis exfoliation and pain, soft silicone is chemically inert, will not chemically react with the wound, and will not affect the healing process of the wound; on top of the soft silicone layer is a foam pad absorbent layer, which can fully absorb skin permeation Sweat or wound exudate; above the absorbent layer of the foam pad is a waterproof and breathable layer, which is made of polyurethane, which has the functions of ventilation and water vapor distribution, and at the same time can be waterproof and prevent bacteria from penetrating. Provides a gentle, safe recovery environment.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1 The utility model is a protective pad for a non-invasive ventilator. By setting a nose bridge pad, two extension strips are arranged on the nose bridge pad. There is a layer of protective pad between the mask and the patient's face, which effectively protects the patient's face and nose bridge, and avoids the occurrence of pressure sores;

2. This utility model is a protective pad for a non-invasive ventilator. The nose bridge pad and the extension bar made of composite layer structure materials have more functions, and the combined functions make the utility model have more advantages;

3. The utility model relates to a protective pad for a non-invasive ventilator, which is simple in structure, convenient and practical.

Detailed ways

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example

As shown in Figures 1 to 2, a protective pad for a non-invasive ventilator of the present invention includes a rectangular nose pad 1 as a whole, two extension strips 2 are arranged on the lower part of the nose pad 1, and the two extension strips 2 are connected to the nose bridge. The axis of the pad 1 forms an acute angle. The corners of the nose bridge pad 1 and the extension strip 2 are designed in a circular arc shape, which can increase the firmness of the sticking. The nose bridge pad 1 and the extension strip 2 are integrated with a composite layer structure Specifically, the materials of the composite layer structure from top to bottom are waterproof and breathable layer 5, foam pad absorption layer 4, and soft polysilicone layer 3, wherein the soft polysilicone layer 3 avoids damage when changing dressings The wound and the surrounding skin do not adhere to the wet wound, but only adhere to the dry tissue, reducing the risk of maceration; the foam pad absorption layer 4 has good compliance, can maintain the integrity of the dressing, prevent deformation, and can better absorb seepage Exudate, sweat, etc.; the waterproof and breathable layer 5 is made of polyurethane, which has the functions of ventilating and emitting water vapor, and can waterproof and prevent bacteria from penetrating at the same time, so as to provide a gentle and safe recovery environment for its wound .

As mentioned above, the utility model can be well realized. the
