Description

A new type of non-invasive ventilator mask decompression device

technical field

The utility model belongs to the technical field of medical appliances, in particular to a novel non-invasive respirator face mask decompression device.

Background technique

Non-invasive ventilator is an important tool for rescuing and treating critically ill patients. It is widely accepted by patients due to its light weight, simple and convenient operation, no need for tracheal intubation or incision, and fewer complications. It has been used in COPD, respiratory failure, In the treatment of patients with heart failure, when using a non-invasive ventilator, it is necessary to wear an elastic and suitable mask for oxygen delivery, but there will also be complications. Among them, 7%-27% of the patients have nasal and facial pressure injuries. In addition, due to Irritant conjunctivitis caused by mask air leakage, in view of this situation, the current clinical nursing often chooses decompression stickers to provide local decompression and prevent air leakage, but decompression stickers have several defects:

1. When wearing the decompression patch, it is easy to not stick to the face. When the patient coughs or drinks water, it needs to be removed, and it needs to be put on again when necessary, which is cumbersome.

2. It is expensive, polluted, and should not be replaced frequently after being wet.

3. The face is deformed after sweating and wet and can no longer be used.

If gauze is used for decompression, the disadvantages are

poor airtightness;

It is easy for gauze debris to enter the patient's airway;

It does not stick to the patient's face and is uncomfortable.

Therefore need to develop a kind of novel non-invasive ventilator mask decompression device, can solve the above problems.

Contents of the invention

In order to solve the above problems, the utility model discloses a new type of non-invasive ventilator mask decompression device, which can effectively prevent pressure injuries on the face and nose. Next, just replace the mask when it is polluted, saving the cost of decompression stickers.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A novel non-invasive ventilator face mask decompression device, comprising a cover body and a decompression sticker, the cover body includes a cover outer layer and a mask inner layer, a deformable bar is arranged above the cover body, and the deformable bar is hot-pressed It is fixed between the outer layer of the cover and the inner layer of the cover. The middle part of the cover is provided with an internal breathing port, and the two sides of the cover are provided with ear hooks. The decompression patch is pasted on the outside of the cover body, the inner breathing port and the outer breathing port overlap at the same position, and the upper edge of the decompression patch is higher than the upper edge of the cover body.

As an improvement of the utility model, the outer layer of the cover and the inner layer of the cover are both non-woven fabric layers.

As an improvement of the utility model, the area of the decompression patch is larger than the contact area between the mask of the non-invasive ventilator and the face.

As an improvement of the utility model, the thickness of the decompression patch is 1-3mm.

As an improvement of the utility model, the tail end of the ear hanger is inclined downward to match the auricle.

As an improvement of the utility model, the mask body is in the shape of a planar structure, and there are folded areas along the lateral direction of the mask body.

The beneficial effects of the utility model are:

1. Plastic ear hooks are used on both sides, which is easy to wear;

2. Effectively prevent facial and nasal pressure injuries;

3. Firmly fixed, fully fit with the face, and keep airtight;

4. No need to take it off when drinking water or coughing, saving time and effort;

5. Just replace the mask when it is polluted, saving the cost of decompression stickers;

6. When the patient's face is sweating, prevent moisture, and replace the mask directly when the mask is wet.

Detailed ways

The utility model will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model.

As shown in Figure 1, a new type of non-invasive ventilator mask decompression device described in the present invention includes a cover body 1 and a decompression sticker 2, and the cover body 1 includes a cover outer layer 3 and a cover inner layer 4. A deformable strip 5 is arranged above the cover body 1, and the deformable strip 5 is hot-pressed and fixed between the cover outer layer 3 and the cover inner layer 4. The middle part of the cover body 1 is provided with an inner breathing port 6, and the cover body 1 Both sides are provided with ear hooks 7, and 7 sets of ear hooks are hung on the patient's ears during use for the positioning of the cover body 1; the decompression patch 2 is diamond-shaped, and the middle part of the decompression patch 2 is provided with an external breathing port 8, The decompression patch 2 is pasted on the outside of the cover body 1, the inner breathing port 6 and the outer breathing port 8 have the same shape and overlap, and the upper edge of the decompression patch 2 is higher than the upper edge of the cover body 1.

A new type of non-invasive ventilator face mask decompression device described in the utility model, the two sides of the mask body 1 are provided with ear hooks 7 (similar to glasses frames, made of plastic), and the tail ends of the ear hangers 7 are inclined downward to meet the auricles. Fit, easy to wear, and will not cause pressure damage to the inside of the auricle. When in use, put the ear hook 7 on the patient's ear, and the patient's mouth and nose are just facing the breathing port and exposed. Cover the ventilator mask on the decompression Stick 2, then pinch the deformable strip 5 to fit the mask to the base of the nose (similar to wearing a mask). The structure of the decompression sticker 2 + double-layer mask can effectively prevent facial pressure injuries. The decompression sticker 2 The upper edge of the upper edge can effectively prevent nasal pressure injuries, prevent facial pressure sores, and increase the comfort of use; and it is completely fitted to the face and keeps airtight; the breathing port reserved in the middle does not need to be removed when drinking or coughing. save time and energy. The breathing port reserved in the middle (including the inner breathing port 6 and the outer breathing port 8 that fit together) can be artificially trimmed in size, and can be applied to patients with different face sizes.

The cover outer layer 3 and the cover inner layer 4 described in the utility model are both non-woven fabric layers, which have good air permeability and are moisture-proof.

The area of the decompression sticker 2 described in the utility model is greater than the contact area between the non-invasive ventilator mask and the face, ensuring that the ventilator mask is completely covered on the decompression sticker 2 when in use, and the thickness of the decompression sticker 2 is 1-3mm, which can Great for decompression.

The cover body 1 described in the utility model is in a planar structure shape, and a wrinkle area 9 is arranged laterally along the mask body. Fit the patient's face, and then glue the decompression patch 2 to the outer layer 3 of the mask. The mask can be replaced directly after the mask is wet or polluted, which saves costs (because the cost of the decompression patch for clinical use is very high).

It should be noted that the above content only illustrates the technical idea of the utility model, and cannot limit the scope of protection of the utility model. For those of ordinary skill in the art, without departing from the principle of the utility model, Several improvements and modifications can also be made, and these improvements and modifications all fall within the protection scope of the claims of the present utility model.
