Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of nasal masks, especially to a pressure-reducing nasal mask for a BIPAP breathing machine. BACKGROUND

[0002] Breathing machines have played a huge role in the treatment of respiratory system critical illness, and a BIPAP (bilevel positive airway pressure) breathing machine is an advanced medical device widely used in the treatment of various respiratory disorders and respiratory failure. It helps patients improve ventilation and gas exchange and improve the quality of life by providing two different pressure levels - inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP). The BIPAP breathing machine is particularly suitable for chronic obstructive pulmonary disease (COPD), heart failure, respiratory failure, sleep apnea, postoperative respiratory support, and other clinical conditions.

[0003] In order to prevent air leakage when using the BIPAP mask, a strap is used to connect the mask to the patient's head, and the mask is tightly attached to the skin of the face. Long-term compression can easily cause pressure injuries. In addition, ear buckles are usually provided on the mask, and then the strap is fixed by being threaded through the ear buckles. When the patient needs to drink water or communicate, etc. for a short time without wearing the mask, the strap and the mask need to be removed as a whole, and then the mask needs to be worn again. The process of removing and wearing the mask requires the patient's head to be lifted, which is more troublesome and increases the patient's discomfort. SUMMARY

[0004] This section aims to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0027] Reference Figures 1-4 As one embodiment of this utility model, a decompression nasal mask for a BIPAP ventilator is provided, comprising:

[0028] The main unit 100 includes a mask 101, an air duct 102 fixed and connected to the front side of the mask 101, a connecting plate 103 fixed to the top of the mask 101, a silicone ring 104 fixed to the rear side of the mask 101, a pressure-reducing auxiliary material 105 fixed to the side of the silicone ring 104 away from the mask 101, a silicone ring 2 106 fixed to the rear side of the connecting plate 103, and a pressure-reducing auxiliary material 2 107 fixed to the side of the silicone ring 2 106 away from the connecting plate 103.

[0029] Wearing unit 200 includes a first strap 201 and a second strap 202. A covering fabric 203 is fixed to the middle of the second strap 202. Two connecting straps 204 are fixed to the covering fabric 203, and the ends of the connecting straps 204 away from the covering fabric 203 are fixed to the first strap 201. A pressure-reducing auxiliary material 205 is fixed to the side of the covering fabric 203 near the mask 101. The pressure-reducing auxiliary material 205 has a thickness of 0.6-0.8cm. The area of ​​the second pressure-reducing auxiliary material 107 is 0.3-0.5cm larger than the edge of the second silicone ring 106. The area of ​​the first pressure-reducing auxiliary material 105 is 0.3-0.5cm larger than the edge of the first silicone ring 104. A fixing component is provided on the first strap 201 for fixing the connecting plate 103 and the first strap 201.

[0030] Among them, a frame-shaped strap 206 is fixed to one end of the first strap 201, and the connecting plate 103 can be embedded in the frame-shaped strap 206. A slot 207 is opened at one end of the frame-shaped strap 206, and one end of the first strap 201 can pass through the slot 207 and slide within the slot 207. A second rough surface 210 and a second hook surface 211 are provided on one side of the first strap 201, and the second rough surface 210 and the second hook surface 211 are bonded together. Ear loops 217 are fixed on both sides of the mask 101. Both ends of the second strap 202 pass through the ear loops 217 and slide within the ear loops 217. Two first rough surfaces 208 and two first hook surfaces 209 are provided on one side of the second strap 202, and the first rough surfaces 208 and the corresponding first hook surfaces 209 are bonded together.

[0031] When wearing the mask 101, after placing the mask 101 on the patient's nose, pass the first strap 201 through the slot 207, and then pull the first strap 201 to adhere the second textured surface 210 and the second hook surface 211, thus fixing the first strap 201 to the patient's head. Then, pass the second strap 202 through the ear loop 217, and pull the second strap 202 to adhere the first textured surface 208 and the first hook surface 209, thus fixing the second strap 202 to the patient's head, thereby completing the wearing of the mask 101. Due to the setting of the first pressure-relieving accessory 105, the second pressure-relieving accessory 107, and the third pressure-relieving accessory 205, pressure injury caused by prolonged pressure can be reduced.

[0032] In addition, four protruding plates 214 are provided on one side of the frame-shaped band 206. An elastic band 216 is fixed on the protruding plate 214. The two corresponding elastic bands 216 are fixed with a positioning ring 215 at the ends away from the protruding plate 214. The fixing component includes two strip plates 212 fixed to one side of the connecting plate 103. The two strip plates 212 are provided with a slot 213 on the side that is close to each other. The positioning ring 215 can be embedded in the slot 213.

[0033] When the mask 101 needs to be temporarily removed, pull the positioning ring 215 to remove it from the slot 213, so that the connecting plate 103 can be removed from the frame strap 206. By folding the second tie 202, the textured surface 208 and the hook surface 209 are separated. The second tie 202 is then removed from the ear loop 217, and the mask 101 can be removed. At this time, the frame strap 206 is still fixed on the patient's forehead, and the first tie 201 is still fixed to the head and will not loosen. When wearing the mask 101 again, simply attach the connecting plate 103 to the patient's forehead, pull the positioning ring 215 to embed it into the slot 213, at which point the elastic band 216 is in a taut state. Then, pass the second tie 202 through the ear loop 217 to glue the textured surface 208 and the hook surface 209 together, and the mask 101 is worn again, making it more convenient to wear again.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
