Abstract
Description
Technical Field
[0001] The utility model relates to the field of auxiliary equipment for use of non-invasive ventilators, in particular to an anti-pressure sore device and a breathing device. Background Art
[0002] Non-invasive ventilator, also known as continuous positive airway pressure therapy machine, is an important and indispensable technology in the modern medical field. It plays a key role in the treatment of chronic respiratory diseases and has made a huge contribution to improving the quality of life of patients.
[0003] Non-invasive ventilators are usually used clinically to treat sleep apnea, type II respiratory failure, pulmonary edema, emphysema, chronic obstructive pulmonary disease and other related diseases. On the one hand, it helps people improve their quality of life by increasing lung ventilation, replacing or improving people's breathing; on the other hand, it can ensure the opening of the upper airway during sleep, which is undoubtedly a hero in ensuring smooth breathing for people with hypoventilation and apnea. Therefore, many patients will also be equipped with a non-invasive ventilator at home to reduce the frequency of hospitalization due to respiratory problems.
[0004] During use, the breathing mask of the non-invasive ventilator must be worn very tightly to prevent air leakage. Therefore, long-term use will cause the forehead, the root of the nose, and the skin on both sides of the nose to be compressed or damaged, causing pressure sores at the root of the nose, forehead, and nasolabial grooves. The pressure at the root of the nose is the most serious. In addition, patients in the ICU are all in poor physical condition. They are very thin and have little facial flesh, which can easily leak air. Therefore, such patients need to press extra hard and tightly, and basically the facial skin will be damaged. In order to solve the problem of pressure sores on the skin, patients are usually asked to buy foam dressings, and then use molds to measure the size of different facial areas of patients and cut the foam dressings into predetermined sizes and stick them on the face, so that the foam dressings are placed between the breathing mask and the face, thereby reducing pressure sores. However, there are still at least the following problems:
[0005] 1. However, many novice nurses, especially patients and their families who use non-invasive ventilators at home, do not know how to cut and cannot cut foam dressings into predetermined shapes and sizes;
[0006] 2. Wearing a mask requires the cooperation of two people. Although one side of the foam dressing is sticky, it is generally not sticky enough to avoid pulling or hurting the skin when it is torn off. Therefore, it is difficult to use. One person needs to hold the foam dressing while the other person wears the mask. It cannot be done by one person alone, and the labor cost is high.
[0007] 3. The breathing mask and foam dressing are not worn professionally. When people are sitting or lying down, they are prone to displacement. At this time, the mask needs to be removed and adjusted repeatedly, which is time-consuming and laborious;
[0008] 4. Due to the dust on the face or the oil and sweat secreted by the human body, the foam dressing cannot be washed and reused. Due to the high price of foam dressing, the cost of use is high;
[0009] 5. Although foam dressings are currently used and the edges of the breathing mask are also made of soft materials, in order to ensure sealing, it still needs to be worn tightly. Since the position of the root of the nose is uneven, the position of the root of the nose is high, and the positions on both sides of the root of the nose are low, and there is less flesh at the root of the nose on the human face, there is still a problem of pressure sores when using non-invasive ventilators for a long time, especially at the root of the nose.

[0053] Including arc-shaped pad 6, see Figure 4 , the arc-shaped pad 6 can be detachably installed in the opening 5;
[0054] See also Figure 1 and Figure 2 The first airbag 1 and / or the second airbag 2 has a fixedly connected strap joint 7; the strap joint 7 is used to connect the strap when in use, so that the patient can wear the product on the head.
[0055] See also Fig.11 and Fig.12 When in use, the anti-pressure sore device of the utility model can be worn on the face first, and then used in conjunction with the breathing mask 14. Firstly, it solves the problem that novice nurses, patients and family members cannot cut the foam dressing into a predetermined shape and size when the current non-invasive ventilator is connected to the breathing mask; secondly, the utility model is worn on the face, which solves the problem that the current foam dressing cannot be completed by a single person and has high labor costs, and is prone to displacement, requires repeated adjustments, and is time-consuming and laborious; thirdly, it solves the problem that the foam dressing cannot be washed and reused after being soiled due to dust on the face or oil and sweat secreted by the human body, and the cost of use is high; the utility model improves the sealing effect of the breathing mask when using a non-invasive ventilator through the cooperation of the first airbag 1 and the second airbag 2 double-layer airbags and the arc-shaped pad 6.
[0056] For further information, see Fig.11 and Fig.12The width of the first airbag 1 and the second airbag 2 is not limited. The attached figure is a schematic diagram. Fig.12 In actual production, the widths of the first airbag 1 and the second airbag 2 can be wider, so that the surface of the first airbag 1 can provide a wider area to abut against the bottom edge of the breathing mask 14;
[0057] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9 The arc-shaped pad 6 has a first placement groove 8 on one side. Figure 4 It is shown that the nose bridge end 4 of the first airbag 1 is at least partially located in the first placement groove 8, that is, Figure 4 As shown, the bottom of the nose bridge end 4 of the first airbag 1 is in the first placement groove 8, and the lower surface of the nose bridge end 4 of the first airbag 1 is detachably connected to the first placement groove 8;

Further, Figure 7It is shown that the horizontal height of the bottom of the left and right ends of the arc-shaped pad 6 is lower than the horizontal height of the nasal root fixing groove 10. In the current existing products, even if additional padding is added at the nasal root, foam dressings are used, and the edge of the breathing mask also has soft materials, the problem cannot be solved, because on the one hand, the added padding cannot be adapted to the contours of different people, and on the other hand, the added padding cannot be well matched with the facial contour, resulting in the inability to ensure sealing; and in order to ensure sealing, the breathing mask still needs to be worn very tightly; more importantly, due to the uneven position of the nasal root, the position of the nasal root is high, the positions of the two sides of the nasal root are low, and the position of the nasal root on the human face is less fleshy, so when a non-invasive ventilator is used for a long time, there are still problems of loose sealing and pressure sores, especially at the nasal root. Therefore, the utility model provides a nasal root fixing groove 10 below the arc-shaped pad 6, and further makes the horizontal height of the bottom of the left and right ends of the arc-shaped pad 6 lower than the horizontal height of the nasal root fixing groove 10, so that the position of the nasal root on the face is protected on the one hand, and the low positions on both sides of the nasal root are supplemented on the other hand. Then, the combination of the first airbag 1 and the second airbag 2 can greatly improve the sealing performance, protect the position of the nasal root from pressure sores or reduce pressure sores.
[0060] See also Figure 5 The first airbag 1 and the second airbag 2 respectively have an inflation port 11, and the inflation port 11 has a sealing cap 12 that is threadedly connected.
[0061] Example 2
[0062] See also Fig.10 The utility model anti-pressure sore device comprises an inflatable airbag 13, wherein the inflatable airbag 13 has a main body and a nose bridge end 4, and the middle part of the nose bridge end 4 has an opening 5;
[0063] It includes an arc-shaped cushion block 6, and the arc-shaped cushion block 6 can be detachably installed in the opening 5;
[0064] The inflatable airbag 13 has a fixedly connected strap connection 7 .
[0065] like Fig.10 As shown, further, one side of the arc-shaped pad 6 has a first placement groove 8, and the other side of the arc-shaped pad 6 has a second placement groove 9; the upper surface of the opening 5 is at least partially located in the first placement groove 8 and is detachably connected to the first placement groove 8; the lower surface of the opening 5 is at least partially located in the second placement groove 9 and is detachably connected to the second placement groove 9.
[0066] like Fig.10As shown, further, there is a nasal root fixing groove 10 below the arc-shaped pad 6, and the nasal root fixing groove 10 is connected with the second placement groove 9 and passes through the front and rear sides of the arc-shaped pad 6; the horizontal height of the bottom of the left and right ends of the arc-shaped pad 6 is lower than the horizontal height of the nasal root fixing groove 10.
[0067] like Fig.10 As shown, further, the inflatable airbag 13 has an inflation port 11, and the inflation port 11 has a sealing cap 12 which is threadedly connected.
[0068] In summary, the present embodiment 2 is the same as the embodiment 1 in its entirety, except that the first airbag 1 and the second airbag 2 of the embodiment 1 are combined into an airbag with a larger thickness and width, and Figure 1 In the first embodiment, the first airbag 1 and the second airbag 2 are partially connected, and the nose bridge end 4 is not connected, thereby forming an opening 5; and Fig.10 As shown, in embodiment 2, a horizontal incision running through the inside and outside is provided at the nose bridge end 4 of the inflatable airbag 13, and the incision is used to form an opening 5 for installing an arc-shaped pad 6 at the position of the opening 5.
[0069] This embodiment 2 achieves the same technical advantages as the embodiment 1 by providing the inflatable airbag 13, so in application, the implementation scheme can be flexibly selected according to the situation.
