Considering the flow path of oxygen and the engagement manner of the rotation locking groove 111 and the rotation locking piece 211, it is preferable that the rotation locking groove 111 is provided in the mask body 100 and the rotation locking piece 211 is provided in the connector 200. When oxygen is delivered, oxygen flows from the second connection end 210 to the first connection end 110, the rotary buckle 211 is located in the rotary clamping groove 111, that is, the second connection end 210 is embedded in the first connection end 110, so that oxygen is prevented from leaking at the connection position of the mask body 100 and the joint 200, and the oxygen inhalation amount of a patient is ensured.

In an optional technical solution of this embodiment, the rotary clamping groove 111 is disposed on the first connection end 110, the rotary fasteners 211 are disposed on the second connection end 210, the rotary clamping groove 111 is disposed along a circumferential direction of an inner side surface of the first connection end 110, the plurality of rotary fasteners 211 are disposed along a circumferential direction of an outer side surface of the second connection end 210 at intervals, and the rotary fasteners 211 are embedded in the rotary clamping groove 111 and can rotate around an axis of the rotary clamping groove 111 by 360 degrees.

In the present embodiment, the number of the rotating buckles 211 is not limited to 3 as shown in fig. 1, and 2, 4 or 5 may be provided.

Further, the rotary buckle 211 can be designed to be a protrusion with a right trapezoid cross section, when the first connection end 110 is connected with the second connection end 210, the upper bottom of the right trapezoid extends into the rotary clamping groove 111, so that the rotary buckle 211 is embedded into the rotary clamping groove 111 with a smaller resistance, or when the first connection end 110 is connected with the second connection end 210, the inclined waist of the right trapezoid extends into the rotary clamping groove 111, and the connection resistance of the rotary buckle 211 and the rotary clamping groove 111 can be reduced. In addition, the rotary buckle 211 can also be designed as a protrusion with a right triangle or rectangle section.

Specifically, as shown in fig. 1, the sectional groove 212 divides the side surface of the second connection end 210 into a plurality of arc-shaped sections, so that the plurality of arc-shaped sections are easily contracted toward the center of the second connection end 210 when the second connection end 210 is connected with the first connection end 110, and the smooth connection between the mask body 100 and the connector 200 is ensured. In this embodiment, the number of the cross-section slots 212 is 3, and may be designed to be 2, 4 or 5 within a reasonable range, and it should be noted that the number of the cross-section slots 212 is related to the connection diameter of the first connection end 110 and the second connection end 210 and the material of the two, and the number of the cross-section slots 212 may be increased when the connection diameter is larger, or the number of the cross-section slots 212 may be increased when the material strength of the two is high, so as to ensure that the second connection end 210 can be contracted and embedded into the first connection end 110. However, the excessive number of the profile grooves 212 will cause the connection between the first connection end 110 and the second connection end 210 to be unstable and to be easily separated.

Further, the sectional slot 212 may be designed to have a rectangular shape as shown in fig. 1, a triangular shape or a quadrilateral shape with other shapes, or other polygonal shapes with more than four sides.

In an optional technical solution of this embodiment, the rotary buckles 211 and the section grooves 212 are arranged alternately along the circumferential direction of the side surface of the second connecting end 210.

Specifically, as shown in fig. 1, in the lateral circumference of the second connection end 210, the number of the rotary fasteners 211 is the same as the number of the section slots 212, and a certain interval exists between the rotary fasteners 211 and the section slots 212, so that the firmness of the connection between the first connection end 110 and the second connection end 210 is ensured, and the problem that the second connection end 210 is not easily shrunk when the two are connected is avoided.

In an optional technical solution of this embodiment, the first connection end 110 is a spherical cavity communicated with the mask body 100, the second connection end 210 is a spherical body communicated with the joint 200, the spherical body is embedded in the spherical cavity and communicated with the mask body 100, and the spherical body can rotate in the spherical cavity.

Specifically, the spherical body is rotatably connected with the spherical cavity, so that the rotational connection between the mask body 100 and the joint 200 is realized, the joint 200 can rotate irregularly in the mask body 100, that is, the joint 200 can rotate 360 degrees around the axis of the first connecting end 110, can swing around the axis of the first connecting end 110, and can also perform a combined motion combining rotation and swing, and similarly, the oxygen delivery conduit connected with the third connecting end 220 of the joint 200 can also synchronously rotate irregularly in the mask body 100 along with the joint 200. When the mask is used, oxygen is input into the mask body 100 through the spherical body of the joint 200 and then inhaled by a patient, when the oxygen source position is fixed, the body position of the patient is changed or the head of the patient is lifted, the joint 200 synchronously rotates irregularly in the first connecting end 110 of the mask body 100 to eliminate the problem of bending or stretching of the oxygen delivery catheter caused by the above situation, avoid the displacement of the mask body 100, relieve the use limitation of the mask, and improve the comfort level of the mask worn by the patient and the oxygen therapy effect.

In the optional technical solution of this embodiment, the spherical cavity is provided with a first opening communicated with the joint 200, and a side wall of the first opening is provided with a notch.

Specifically, when the first connection end 110 is connected with the second connection end 210, the spherical body is embedded into the spherical cavity from the first opening, and the first opening is more easily expanded outwards under the action force of the spherical body due to the design of the notch, so that the spherical cavity is not damaged when being embedded. It should be noted that the number of the notches is controlled within a reasonable range according to the diameter of the spherical body and the material of the spherical cavity, and in this embodiment, the number of the notches can be 3, 4 or 5. Furthermore, the depth of the notch on the side wall of the first opening is set as required, so that the first opening can pass through the spherical body, and the first opening can be ensured to be restored to the state before expansion after the spherical body is embedded into the spherical cavity.

In an optional technical solution of this embodiment, the spherical body is provided with a through hole, and a diameter of the through hole gradually increases along a direction away from the joint 200.

In this embodiment, after the first connection end 110 is connected to the second connection end 210, the through hole is located in the spherical cavity as a passage for communicating the mask body 100 and the joint 200, and the diameter of the through hole gradually increases along a direction away from the joint 200, so as to ensure the oxygen delivery amount. Specifically, when the connector 200 rotates relative to the mask body 100, the inner wall of the spherical cavity covers a part of the opening of the through hole, which affects the amount of oxygen input into the mask body 100, and the diameter of the opening of the through hole is larger than the diameter of the connection part of the through hole and the connector 200, thereby eliminating the problem of insufficient oxygen and ensuring that the patient can absorb the set amount of oxygen.

In an optional technical solution of this embodiment, the interior of the spherical body is hollow, and the spherical body is provided with a second opening communicated with the joint 200 and a third opening communicated with the mask body 100, and a diameter of the third opening is larger than a diameter of the second opening.

In this embodiment, when a patient inhales oxygen, oxygen in the connector 200 enters the interior of the spherical body through the second opening, and then flows into the mask body 100 from the interior of the spherical body through the third opening, and the diameter of the third opening is larger than that of the second opening, so that the amount of oxygen inhaled by the patient is ensured. Specifically, when the connector 200 rotates relative to the mask body 100, a portion of the third opening is covered by the inner wall of the spherical cavity, which affects the amount of oxygen input into the mask body 100, and the diameter of the third opening and the amount of oxygen input into the inner cavity of the spherical cavity eliminate the above problem, thereby ensuring that the patient can absorb the set amount of oxygen.

Further, the spherical body is hollow, so that the whole weight of the joint 200 is reduced, namely, the oppression of the mask on the face of a patient is reduced, the comfort level of the patient wearing the mask is enhanced, and the practicability of the mask is improved.

In an optional technical solution of this embodiment, a sealing sleeve is sleeved at a connection position of the first connection end 110 and the second connection end 210.

Specifically, after the first connecting end 110 is connected with the second connecting end 210, the spherical cavity is wrapped outside the spherical body, the sealing sleeve is wrapped outside the spherical cavity and completely seals the first opening, and the sealing sleeve plays a role in sealing the interface between the first connecting end 110 and the second connecting end 210, so that oxygen is prevented from leaking to the outside through the spherical cavity. In addition, the sealing sleeve enhances the connection tightness between the first connection end 110 and the second connection end 210, and prevents the first connection end 110 from separating from the second connection end 210 when the first connection end rotates in the second connection end 210.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made on the technical solutions described in the foregoing embodiments, or some or all of the technical features of the present invention may be replaced by other technical features of the present invention without departing from the scope of the technical solutions of the present invention.
