Description

Technical Field

[0001] The present application relates to the technical field of medical masks, and in particular to a non-invasive breathing mask. Background Art

[0002] The non-invasive ventilator is a medical device for treating respiratory failure. It is also widely used in the treatment of heart failure. The benefits of its clinical application include: prolonging the inhalation time to facilitate the distribution of gas, and facilitating the distribution and diffusion of atomized inhaled drugs in the lungs. When using the non-invasive ventilator, it must be used together with the non-invasive ventilator mask. The mask is worn on the user's face to ensure that the gas provided by the non-invasive ventilator can be effectively inhaled by the user.

[0003] However, when a patient wears a respiratory mask and needs to use a nasogastric tube or a nasojejunal feeding tube, the respiratory mask will be stretched, causing the respiratory mask to not fit the patient's face, resulting in a gap that causes air leakage in the respiratory mask, affecting the patient's oxygen supply and treatment.

[0004] The utility model patent with the authorization announcement number CN217311507U disclosed in the Chinese patent literature discloses a "non-invasive breathing mask", and specifically discloses a mask and a strap body, two buckles are fixedly connected to the side wall of the mask, and the two ends of the strap body are respectively fixedly connected to the two buckles, and the end of the mask that fits the patient's face is fixedly connected to a silicone cushion, and a trapezoidal notch is opened through the side wall of the silicone cushion, and a detachable sealing block is installed on the inner wall of the trapezoidal notch, and an arc groove is opened at the end of the sealing block opposite to the mask, and the two arc grooves are connected to each other to form a circular through hole matching the nasogastric tube and the nasojejunal feeding tube. The utility model connects the two arc grooves by connecting the sealing block to the mask, which is conducive to the connection of the two arc grooves to form a circular through hole connected to the inside of the mask, thereby facilitating the insertion of the nasogastric tube or the nasojejunal feeding tube into the mask from the circular through hole and ensuring the sealing of the mask and the patient's face, avoiding air leakage.

[0005] However, in the prior art disclosed in this patent, the non-invasive breathing mask may easily cause the gastric tube to fall off when it is removed in an emergency, which not only increases the patient's pain but also may affect the patient's treatment effect.

[0031] The following further elaborates on the present utility model with reference to the accompanying drawings so that those skilled in the art can implement it according to the text of the specification.

[0032] To achieve the above object,

[0033] Referring to Figure 1 - Figure 2 , an embodiment of the present application provides a non-invasive breathing mask, which includes a mask body 1, an air inlet pipe joint 2, a strap body 3, a pipe installation device 4, a gastric tube fixing device 5, and an emergency detachment device 6;

[0034] Two buckles 11 are fixedly connected to the side wall of the mask body 1, and both ends of the strap body 3 are respectively connected to the two buckles 11. The pipe installation device 4 is installed outside the mask body 1, and the air inlet pipe joint 2 is installed on the pipe installation device 4. The pipe installation device 4 is used for installing the air inlet pipe;

[0035] The emergency detachment device 6 is detachably installed on the mask body 1, and the gastric tube fixing device 5 is detachably installed on the pipe installation device 4 through the emergency detachment device 6.

[0036] In this embodiment, the mask body 1 is made of a soft and transparent medical material to ensure comfortable wearing.

[0037] The strap body 3 is used to fix the mask body 1 on the patient's face. It is made of elastic material and can be adjusted according to the size of the patient's head.

[0038] The pipe installation device 4 is a rectangular structure with a hollow interior. It is installed on the side of the mask body 1 facing away from the patient and is connected to the interior of the mask body 1. The material used for the pipe installation device 4 is harder than that of the mask body 1 and is used to install the inlet pipe and the gastric tube.

[0039] The gastric tube fixing device 5 is installed on the side of the pipe installation device 4 to facilitate the passage of the gastric tube through the mask body.

[0040] The inlet pipe connector 2 is installed at one end of the pipe installation device 4 away from the mask body to facilitate the connection of the inlet pipe.

[0041] A groove is provided on one side of the mask body 1. The shape of the emergency detachment device 6 is adapted to the shape of the groove. When the emergency detachment device 6 is installed on the mask body 1, it can exactly fill the groove, and at the same time, a circular through-hole can be formed near the middle part of the mask body 1 for installing the gastric tube fixing device 5. When the emergency detachment device 6 and the gastric tube fixing device 5 are installed, the surface of the mask body 1 can be kept sealed completely.

[0042] Among them, referring to Figure 3 , the gastric tube fixing device 5 includes an adjusting member 51 and a sealing ring 52. The adjusting member 51 passes through the through-hole, and the sealing ring 52 is used to seal the through-hole. The gastric tube passes through the adjusting member 51, and the adjusting member 51 passes through the mask body 1. The angle between the gastric tube and the mask body 1 can be adjusted by the adjusting member 51. The adjusting member 51 can be a telescopic fixed clip, and the fixed clip is provided with anti-slip lines to ensure that the gastric tube is not easy to slide in the fixed clip.

[0043] Further, an annular groove can be provided circumferentially on the outer side of the sealing ring 52. The groove is used in cooperation with the through-hole so that one end of the emergency detachment device 6 close to the mask body 1 can be stuck by the groove.

[0044] Optionally, the emergency detachment device 6 and the mask body 1 are adhered through a tape 12. While using the tape 12 to achieve the connection, it can also enhance the sealing effect between the emergency detachment device 6 and the mask body 1. When it is necessary to remove the emergency detachment device 6 from the mask body 1, the emergency detachment device 6 can be disassembled by pulling the tape 12, so as to facilitate the removal of the gastric tube fixing device 5 from the mask body 1, so that the non-invasive breathing mask can be quickly removed while avoiding the detachment of the gastric tube in case of emergency.

[0045] Optionally, a convex block 61 is provided at one end of the emergency detachment device 6 away from the pipe installation device 4, and an elastic cord 13 is provided on the mask body 1. The elastic cord 13 is wound around the convex block 61.

[0046] One end of the emergency detachment device 6 is stuck by the groove of the sealing ring 52, and the other end is fixed to the emergency detachment device 6 by winding the elastic rope 13 around the bump 61. When it is necessary to remove the gastric tube fixing device 5, first remove the elastic rope 13 from the bump 61, and then pull the bump 61 to drive the emergency detachment device 6 to detach from the mask body 1, thereby removing the gastric tube fixing device 5.

[0047] Wherein, the number of the elastic ropes 13 can be set to two, which are respectively arranged on both sides of the emergency detachment device 6, so as to strengthen the fixing effect on the emergency detachment device 6.

[0048] It should be noted that the detachable connection between the emergency detachment device 6 and the mask body 1 in this embodiment by means of the adhesive tape 12 and the elastic rope 13 is only a preferred embodiment of this embodiment. In other embodiments, detachable connection can also be achieved by means of snap connection or bolts, etc. However, adhesion by the adhesive tape 12 has a better sealing effect and is relatively easy to disassemble.

[0049] Optionally, a rubber soft pad 14 is installed on the inner side of the mask body 1 in this embodiment, so that the mask body 1 can fit more closely to the patient's face, strengthen the sealing effect of the mask body 1, and be softer at the same time. One side of both ends of the strap body 3 is provided with a hook-and-loop fastener female sticker 31 and a hook-and-loop fastener male sticker 32. After one end of the strap body 3 passes through one of the buckles 11, bend the strap body 3 so that the hook-and-loop fastener female sticker 31 and the hook-and-loop fastener male sticker 32 at the corresponding end are adhered. By setting the hook-and-loop fastener, it is convenient to adjust the length of the strap body 3, so as to be applicable to patients with different head shapes.

[0050] Optionally, an air outlet hole 15 is provided on one side of the mask body 1 in this embodiment, and a one-way valve 7 is provided in the air outlet hole 15. A one-way valve 7 is installed on the air inlet pipe joint 2.

[0051] By providing a one-way valve through the air inlet pipe joint 2, the air flow output by the ventilator can be effectively delivered to the patient's respiratory tract, and at the same time, the gas exhaled by the patient is prevented from flowing back into the ventilator or the air inlet pipe.

[0052] By providing a one-way valve 7 through the air outlet hole 15, the main function is to ensure that when exhaling, the valve can automatically open to allow the exhaled gas to be discharged smoothly, reduce the moisture accumulated inside the mask, so that breathing is easier and more comfortable. When not breathing or inhaling, the valve will automatically stick tightly to seal to maintain the protection effect and prevent external pollutants or germs from entering the mask interior.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, it is obvious that this application is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms.
