Description

Technical Field

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

[0002] At present, most medical and health units still use triangular oxygen masks that are different from the human face contour. This type of oxygen mask has poor sealing performance, and the edge part is easy to flip over. Gas is easy to leak during use. In order to make it seal, the mask must be tightly fastened to the patient's face, which is very uncomfortable for the patient. After long-term use, the patient's face is often injured, which is especially unsuitable for infants and newborns. On the other hand, most of the existing oxygen masks are fixed in shape and their size cannot be adjusted. Especially in the process of use by children, due to the individual growth differences of children, the existing oxygen masks cannot meet the use requirements of children of all ages.

[0003] Of course, there are some respirators with adjustable sizes in the prior art. For example, the patent with publication number CN206007758U discloses a novel respirator for children with adjustable size. However, the mask in this solution cannot be locked and fixed after the length is adjusted. Therefore, in actual use of the respirator, since the length of the mask body is not locked, it is easy for the user to not fit the mask properly after the length of the mask body changes, resulting in poor sealing. Utility Model Content

[0004] The embodiment of the present application provides a breathing mask to solve the problems raised by the background technology.

[0005] An embodiment of the present application provides a breathing mask, which includes a mask body and an elastic tightening strap, wherein the tightening strap is used to enable the mask body to be attached to the user's face; the mask body is provided with an air inlet pipe joint, which is used to connect with the breathing tube of the respirator; wherein the mask body includes a first cover body and a second cover body, the air inlet pipe joint is provided on the first cover body, the first cover body and the second cover body are slidably connected, and a locking assembly is provided on the first cover body, which is used to prevent the second cover body from sliding relative to the first cover body.

[0006] In this solution, by arranging fastening belts on both sides of the mask body, the mask body can be closely attached to the user's face through the fastening belts; the mask body is provided with an air inlet pipe joint, which can be connected to the breathing tube of the respirator. The mask body is divided into two parts, namely a first cover body and a second cover body, and the first cover body and the second cover body are slidably connected, so that when in use, the second cover body can be pulled out or inserted on the first cover body, thereby changing the overall size of the breathing mask to meet the use requirements of children of different age groups. In addition, by arranging a locking assembly on the first cover body, the locking assembly can unlock and lock the length of the breathing mask. When the size of the breathing mask needs to be adjusted, the locking assembly is unlocked, so that the second cover body can slide relatively on the first cover body. After the length of the combination of the first cover body and the second cover body is adjusted to the right position, the locking assembly is used to lock the breathing mask, and the length of the breathing mask is fixed. In this way, during the use of the breathing mask, there will be no relative sliding between the first cover body and the second cover body, resulting in a gap between the breathing mask and the user. The length of the breathing mask is more reliable, the fit between the breathing mask and the user is more reliable, and the sealing is relatively better.

[0007] In some embodiments, the first cover body has a groove for slidingly matching with the second cover body, and a side of the second cover body close to the groove is a sliding part, which is inserted into the groove and slidingly matches with the groove.

[0008] In the above technical solution, by providing a groove in the first cover body for sliding cooperation with the second cover body, the groove can allow the sliding part of the second cover body to be inserted into the groove. When adjusting the length of the breathing mask, it is only necessary to let the sliding part slide in the groove, and the adjustment is convenient and quick.

[0009] In some embodiments, a blocking portion is formed on a side of the groove close to the second cover body, and the blocking portion is used to prevent the sliding portion of the second cover body from being separated from the groove.

[0010] In the above technical solution, a blocking part is provided on one side of the groove, which can prevent the sliding part from detaching from the groove. In this way, when adjusting the length of the mask body, the first cover body and the second cover body are always a whole, and will not loosen, and the integrity is relatively better.

[0011] In some embodiments, the locking assembly includes a locking rod, which is threadedly engaged with the first cover body. One end of the locking rod is located outside the first cover body, and the other end extends into the groove. The locking rod is used to support the upper surface of the second cover body to prevent the second cover body from sliding relative to the first cover body.

[0012] In the above technical solution, the locking rod and the first cover body are threadedly matched. The locking rod can be extended and retracted by rotating the locking rod, and the sliding part of the second cover body is supported and fixed by the locking rod. The adjustment is convenient and quick. When unlocking is required, it is only necessary to loosen the locking rod outward so that the second cover body can slide relative to the first cover body. When the length of the breathing mask is adjusted to the right length, the locking rod is tightened to make the locking rod close to the second cover body. The operation is convenient and quick, and the structure is simple.

[0013] In some embodiments, a plurality of locking grooves are distributed on the upper surface of the sliding portion along the sliding direction thereof, and the locking rod is used to abut against the locking grooves to prevent the second cover body from sliding relative to the first cover body.

[0014] In the above technical solution, by forming a plurality of locking grooves on the surface of the sliding part, compared with the locking rod directly abutting against the surface of the sliding part, the locking groove can have a better blocking and limiting effect on the locking rod. In this way, the locking rod is plugged into the corresponding locking groove, thereby better preventing the second cover body and the first cover body from sliding relative to each other, and the limiting effect is better.

[0015] In some embodiments, a guide mechanism is disposed between the first cover body and the second cover body, and the guide mechanism is used to guide the first cover body and the second cover body to slide along a first direction.

[0016] In the above technical solution, by providing a guide mechanism between the first cover body and the second cover body, the guide mechanism can play a certain guiding role, guiding the first cover body and the second cover body when adjusting the length direction of the breathing mask, and it is not easy for the first cover body and the second cover body to deviate in the left and right directions, and the stability of the breathing mask during length adjustment is better.

[0017] In some embodiments, the guide mechanism includes a convex ridge and a concave portion, the convex ridge protrudes along the first direction and is distributed on the surface of the groove, the concave portion is located on the surface of the second cover body, and the concave portion cooperates with the convex ridge for guidance.

[0018] In the above technical solution, through the combination of the convex ridge and the concave portion, the concave portion and the convex ridge are guided and matched, so that during the relative sliding process of the first cover body and the second cover body, the concave portion and the convex ridge are always embedded and matched, thereby guiding the sliding direction of the first cover body and the second cover body, and it is not easy for the first cover body and the second cover body to deviate in the left and right directions.

[0019] In some embodiments, the number of guide mechanisms is set to two groups, and the two groups of guide mechanisms are respectively located on the left and right sides of the mask body.

[0020] In the above technical solution, by setting the number of guide mechanisms to two groups, the two groups of guide mechanisms are distributed in the left and right directions, and the two guide mechanisms cooperate with each other, which can further improve the sliding stability of the first cover body and the second cover body.

[0021] In some embodiments, an elastic sealing layer is disposed on the surface of the sliding portion, and the sealing layer is used to achieve a sealing fit between the sliding portion and the groove of the first cover body.

[0022] In the above technical solution, a sealing layer is provided on the surface of the sliding part, and the sealing layer is made of elastic material. When the sliding part is slidably arranged in the groove, the groove can provide a pressing force to the sealing layer, so that the sealing layer is squeezed and deformed. In this way, the space between the sliding part and the groove is filled with the sealing layer, thereby ensuring the sealing at the junction of the first cover body and the second cover body.

[0023] In some embodiments, a skin-contacting layer is disposed around one side of the bottom of the mask body, and the material of the skin-contacting layer is a memory foam pad.

[0024] In the above technical solution, by providing a skin-contacting layer at the bottom of the mask body, the skin-contacting layer of the memory foam pad is elastic, and when in contact with the user's face, it is not easy to cause pressure marks on the patient's face, and the patient's use experience is better.

[0035] Example

[0036] The present application embodiment provides a breathing mask, see Figure 1 and Figure 2The breathing mask 100 includes a mask body 10 and an elastic tightening belt 20, the tightening belt 20 is used to make the mask body 10 fit the user's face; the mask body 10 is provided with an air inlet pipe joint 30, the air inlet pipe joint 30 is used to communicate with the breathing tube of the respirator; wherein, the mask body 10 includes a first cover body 11 and a second cover body 12, the air inlet pipe joint 30 is arranged on the first cover body 11, the first cover body 11 and the second cover body 12 are slidably connected, and a locking assembly is arranged on the first cover body 11, the locking assembly is used to prevent the second cover body 12 from sliding relative to the first cover body 11.

[0037] In this solution, by arranging fastening belts 20 on both sides of the mask body 10, the mask body 10 can be closely attached to the user's face through the fastening belts 20; the mask body 10 is provided with an air inlet pipe joint 30, which can be connected to the breathing tube of the respirator. The mask body 10 is divided into two parts, namely a first cover body 11 and a second cover body 12, and the first cover body 11 and the second cover body 12 are slidably connected, so that when in use, the second cover body 12 can be pulled out or inserted on the first cover body 11, thereby changing the overall size of the breathing mask to meet the use requirements of children of different age groups. In addition, by arranging a locking assembly on the first cover body 11, the locking assembly can realize unlocking and locking of the length of the breathing mask. When the size of the breathing mask 100 needs to be adjusted, the locking assembly is unlocked, so that the second cover body 12 can slide relatively on the first cover body 11. After the length of the combination of the first cover body 11 and the second cover body 12 is adjusted to the right position, the locking assembly is used to lock the breathing mask, and the length of the breathing mask 100 is fixed. In this way, during the use of the breathing mask, the first cover body 11 and the second cover body 12 will not slide relative to each other, resulting in a gap between the breathing mask 100 and the user. The length size of the breathing mask 100 is more reliable, the breathing mask 100 fits the user's face more reliably, and the sealing is relatively better.

[0038] The mask body 10 is provided with a connector at a position corresponding to the tightening belt 20, and the tightening belt 20 is mounted on the connector. The mask body 10 is provided with a ventilation hole 80, and a one-way breathing valve is provided at the position of the ventilation hole 80. Of course, the number of the ventilation hole 80 can be one or more.

[0039] In some embodiments, the first cover body 11 has a groove 110 for slidingly matching the second cover body 12, and the side of the second cover body 12 close to the groove 110 is a sliding portion 120, and the sliding portion 120 is inserted into the groove 110 and slides with the groove 110. By having the groove 110 for slidingly matching the second cover body 12 in the first cover body 11, the groove 110 can be used for the sliding portion 120 of the second cover body 12 to be inserted into the groove 110, and when adjusting the length of the respiratory mask, it is only necessary to let the sliding portion 120 slide in the groove 110, and the adjustment is convenient and quick.

[0040] In some embodiments, the groove 110 is formed with a blocking portion (not shown in the figure) on one side close to the second cover body 12, and the blocking portion is used to prevent the sliding portion 120 of the second cover body 12 from being separated from the groove 110. By providing a blocking portion on one side of the groove 110, the blocking portion can prevent the sliding portion 120 from being separated from the groove 110, so that when the length of the mask body is adjusted, the first cover body 11 and the second cover body 12 are always a whole, and will not be loose, and the integrity is relatively better.

[0041] The blocking portion is arranged at the end of the groove, thereby reducing the caliber of the end of the groove, and the cross-sectional size of one side of the end of the sliding portion is larger than the caliber of the end of the groove, so that the sliding portion cannot be separated from the groove. Of course, the blocking portion and the groove 110 are detachably connected, for example, the blocking portion and the groove 110 are screwed. When the first cover body 11 or the second cover body 12 needs to be maintained or replaced, it is only necessary to remove the blocking portion, so that the first cover body 11 and the second cover body 12 can be separated, and the corresponding first cover body 11 or the second cover body 12 can be replaced.

[0042] In some embodiments, the locking assembly includes a locking rod 40, which is threadedly engaged with the first cover body 11, one end of the locking rod 40 is located outside the first cover body 11, and the other end extends into the groove 110. The locking rod 40 is used to abut against the upper surface of the second cover body 12 to prevent the second cover body 12 from sliding relative to the first cover body 11. The locking rod 40 is threadedly engaged with the first cover body 11, and the locking rod 40 can be extended and retracted by rotating the locking rod 40. The locking rod 40 is used to abut and fix the sliding portion 120 of the second cover body 12, and the adjustment is convenient and fast. When unlocking is required, it is only necessary to loosen the locking rod 40 outward, so that the second cover body 12 can slide relative to the first cover body 11. When the length of the breathing mask 100 is adjusted to the desired position, the locking rod 40 is tightened to abut against the second cover body 12. The operation is convenient and fast, and the structure is simple.

[0043] Of course, the outer end of the locking rod 40 is located on the front side of the first cover body 11, that is, the outer end of the locking rod 40 is located on the side away from the user's face, which is convenient for adjusting the locking rod 40 and will not interfere with the user's face.

[0044] In some embodiments, the upper surface of the sliding portion 120 is provided with a plurality of locking grooves 121 along the sliding direction thereof, and the locking rod 40 is used to abut against the locking grooves 121 to prevent the second cover body 12 from sliding relative to the first cover body 11. By forming a plurality of locking grooves 121 on the surface of the sliding portion 120, compared with the locking rod 40 directly abutting against the surface of the sliding portion 120, the locking grooves 121 can have a better blocking and limiting effect on the locking rod, so that the locking rod 40 is plugged into the corresponding locking grooves 121, thereby better preventing the second cover body 12 and the first cover body 11 from sliding relative to each other, and the limiting effect is better.

[0045] The cross-sectional shape of the locking groove 121 may be an arc, and a plurality of locking grooves 121 are distributed in a wave shape on the surface of the sliding portion 120. The arc-shaped locking groove 121 has a certain guiding effect. When the locking rod contacts the arc of the locking groove 121, during the downward pressing process of the locking rod 40, the second cover body 12 and the first cover body 11 can be guided to move and position adaptively, that is, the second cover body 12 and the first cover body 11 are slightly adaptively fine-tuned, so that the locking rod abuts against the bottom of the locking groove 121, thereby locking the length of the breathing mask.

[0046] In some embodiments, a guide mechanism 50 is provided between the first cover body 11 and the second cover body 12, and the guide mechanism 50 is used to guide the first cover body 11 and the second cover body 12 to slide along the first direction. By providing the guide mechanism 50 between the first cover body 11 and the second cover body 12, the guide mechanism 50 can play a certain guiding role, guiding the first cover body 11 and the second cover body 12 to adjust the length direction of the breathing mask, and it is not easy for the first cover body 11 and the second cover body 12 to deviate in the left and right directions, and the stability of the breathing mask during length adjustment is better.

[0047] The first direction is the moving direction of the first cover body 11 and the second cover body 12, and the first direction is perpendicular to the left-right direction. The first direction is also the length direction of the breathing mask, and the left-right direction is the width direction of the breathing mask.

[0048] Optionally, the guide mechanism 50 includes a convex rib 52 and a concave portion 51, wherein the convex rib 52 protrudes along the first direction and is distributed on the surface of the groove 110, and the concave portion 51 is located on the surface of the second cover body 12, and the concave portion 51 is guided and matched with the convex rib 52. Through the combination of the convex rib 52 and the concave portion 51, the concave portion 51 is guided and matched with the convex rib 52, so that during the relative sliding process of the first cover body 11 and the second cover body 12, the concave portion 51 and the convex rib 52 are always embedded and matched, thereby guiding the sliding direction of the first cover body 11 and the second cover body 12, and it is not easy for the first cover body 11 and the second cover body 12 to deviate in the left and right directions.

[0049] The concave portion 51 has an arc-shaped cross section. Of course, the shape of the convex ridge 52 matches the shape of the concave portion 51 .

[0050] In some embodiments, the number of guide mechanisms 50 is set to two groups, and the two groups of guide mechanisms 50 are respectively located on the left and right sides of the mask body. By setting the number of guide mechanisms 50 to two groups, the two groups of guide mechanisms 50 are distributed in the left and right directions, and the two guide mechanisms 50 cooperate together, the sliding stability of the first cover body 11 and the second cover body 12 can be further improved.

[0051] In some embodiments, an elastic sealing layer 70 is disposed on the surface of the sliding portion 120, and the sealing layer 70 is used to seal the sliding portion 120 with the groove 110 of the first cover body 11. By disposing the sealing layer 70 on the surface of the sliding portion 120, and the sealing layer 70 is made of elastic material, when the sliding portion 120 is slidably disposed in the groove 110, the groove 110 can provide a pressing force to the sealing layer 70, so that the sealing layer 70 is squeezed and deformed, so that the space between the sliding portion 120 and the groove 110 is filled with the sealing layer 70, thereby ensuring the sealing performance at the junction of the first cover body 11 and the second cover body 12.

[0052] In some embodiments, a skin-contacting layer 60 is disposed around one side of the bottom of the mask body 10, and the material of the skin-contacting layer 60 is a memory foam pad. By disposing the skin-contacting layer 60 at the bottom of the mask body 10, the skin-contacting layer 60 of the memory foam pad is elastic, and when in contact with the user's face, it is not easy to produce pressure marks on the patient's face, and the patient's use experience is better.

[0053] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0054] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
