Description

Technical Field

[0001] The utility model relates to the technical field related to breathing masks, in particular to a mask structure for a breathing machine. Background Art

[0002] The face mask is a crucial component of an air respirator, fitting snugly to the user's face and preventing the intrusion of harmful gases. Typically made of chemically and heat-resistant materials, it comes in both full-face and half-face versions. These masks are typically used in conjunction with a ventilator, providing regulated oxygen or a gas mixture for artificial ventilation and maintaining the patient's respiratory function.

[0003] When an existing ventilator mask is in use, the ventilator and the mask are connected by an oxygen delivery tube. The delivery tube delivers the oxygen provided by the ventilator to the mask for use by the patient. To ensure normal oxygen supply to the patient, the connection between the existing delivery tube and the mask is usually a snap-on method. The delivery tube is inserted into the mask. However, if there is interference from external forces, the delivery tube is likely to be detached from the mask, resulting in interruption of oxygen supply and affecting the patient's respiratory treatment. Utility Model Content

[0004] The purpose of the present invention is to provide a mask structure for a ventilator to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A mask structure for a ventilator, comprising a mask, wherein the mask is provided with an interface penetrating the mask, a connecting tube is movably provided on the interface, and at least one group of strip blocks is formed on the inner wall of the connecting tube;

[0007] It also includes a breathing tube, which is connected to an elastic extrusion piece. When the breathing tube is connected to the connecting tube, the strip block can be inserted into the limiting groove formed on the outer wall of the breathing tube and squeeze the elastic extrusion piece.

[0008] As described above, the mask structure for a ventilator: a hemispherical groove is formed in one end of the interface away from the mask, a plug is rollably arranged in the hemispherical groove, and the plug is fixedly connected to the connecting pipe.

[0009] The mask structure for a respirator as described above: the plug is designed to be spherical in shape.

[0010] The mask structure for a respirator as described above: a sealing ring with an annular structure is provided on the inner wall of the end of the connecting tube away from the plug.

[0011] The respirator mask structure as described above: the elastic extrusion member comprises a sleeve arranged along the axial direction of the breathing tube and fixedly connected to the breathing tube, and an extrusion block is slidably arranged in the sleeve;

[0012] It also includes a spring, which is arranged in the sleeve and sleeved on the breathing tube. One end of the spring abuts against the inner end of the sleeve, and the other end abuts against the extrusion block.

[0013] The mask structure for a respirator as described above: a limiting end is formed on one end of the sleeve close to the extrusion block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: when the breathing tube is connected to the connecting tube, the bar block is aligned with the limiting groove and then inserted. When the breathing tube is driven to move relative to the connecting tube, the connecting tube squeezes the elastic extrusion part. The elastic extrusion part is compressed to store elastic potential energy, which controls the rotation of the breathing tube relative to the connecting tube and then releases it. Under the action of the elastic extrusion part, the breathing tube and the connecting tube are locked, preventing the breathing tube from being detached from the connecting tube when pulled by external force, thereby affecting the oxygen delivery work.

[0021] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0022] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0023] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0024] See also Figures 1 to 5 In an embodiment of the present invention, a mask structure for a ventilator includes a mask 1, an interface 2, a connecting tube 4, a bar block 401, a breathing tube 5, a limiting groove 501, and an elastic extrusion member.

[0025] For details, please refer to Figure 1 、 Figure 4 and Figure 5 ,include;

[0026] A mask 1 is provided with an interface 2 penetrating the mask 1 , a connecting tube 4 is movably provided on the interface 2 , and at least one group of strip blocks 401 is formed on the inner wall of the connecting tube 4;

[0027] It also includes a breathing tube 5, which is connected to an elastic extrusion piece. When the breathing tube 5 is connected to the connecting tube 4, the strip block 401 can be inserted into the limiting groove 501 formed on the outer wall of the breathing tube 5 and squeeze the elastic extrusion piece.

[0028] It should be noted that the limiting groove 501 is divided into a first strip groove, a second arc groove, and a third strip groove. When the breathing tube 5 is connected to the connecting tube 4, the strip block 401 is aligned with the first strip groove so that the strip block 401 can be inserted into the first strip groove. At this time, the breathing tube 5 moves relative to the connecting tube 4, and the strip block 401 is slidably set in the first strip groove. When the strip block 401 moves to the end of the first strip groove, it is restricted by the first strip groove and the breathing tube 5 cannot be inserted further. At this time, the breathing tube 5 is rotated, and the direction of rotation of the breathing tube 5 is along the direction of the second arc groove, so that the strip block 401 slides in the second arc groove. After the strip block 401 rotates to the end of the second arc groove, the force on the breathing tube 5 is stopped. Under the action of the elastic extrusion member, the strip block 401 is stuck in the second strip groove to realize the detachable connection between the breathing tube 5 and the connecting tube 4, and can prevent the breathing tube 5 from being separated from the connecting tube 4.

[0029] In detail, in this embodiment, the mask structure for a ventilator described in the utility model is adopted. When the breathing tube 5 is connected to the connecting tube 4, the bar block 401 is aligned with the limiting groove 501 and then inserted, driving the breathing tube 5 to move relative to the connecting tube 4. The connecting tube 4 squeezes the elastic extrusion part, and the elastic extrusion part is compressed to store elastic potential energy, which controls the breathing tube 5 to rotate relative to the connecting tube 4 and then releases it. Under the action of the elastic extrusion part, the breathing tube 5 and the connecting tube 4 are locked to prevent the breathing tube 5 from being detached from the connecting tube 4 when pulled by external force, thereby affecting the oxygen delivery work.

[0030] See also Figure 2 A hemispherical groove is formed in one end of the interface 2 away from the mask 1 , a plug 3 is rollingly arranged in the hemispherical groove, and the plug 3 is fixedly connected to the connecting pipe 4 .

[0031] Preferably, the plug 3 is designed to be spherical in shape.

[0032] To elaborate, the plug 3 is designed with a spherical structure so that the plug 3 can automatically rotate on the interface 2, wherein the groove is larger than the hemisphere to prevent the plug 3 from falling from the interface 2. The groove larger than the hemisphere can limit the separation of the plug 3 from the interface 2. After the breathing tube 5 is connected to the connecting tube 4, under the action of the plug 3, the breathing tube 5 can freely adjust its direction and prevent the breathing tube 5 from being twisted due to external forces such as pulling.

[0033] Preferably, a sealing ring 6 with an annular structure is provided on the inner wall of one end of the connecting pipe 4 away from the plug 3 .

[0034] When the connecting tube 4 and the breathing tube 5 are inserted and connected, there is a gap between the inner wall of the connecting tube 4 and the outer wall of the breathing tube 5. In order to prevent oxygen from leaking from the gap during delivery, the setting of the sealing ring 6 can ensure that the oxygen is completely delivered to the mask 1 after the breathing tube 5 and the connecting tube 4 are connected.

[0035] See also Figure 4 and Figure 5 The elastic extrusion member includes a sleeve 7 arranged along the axial direction of the breathing tube 5 and fixedly connected to the breathing tube 5, and an extrusion block 9 is slidably arranged in the sleeve 7;

[0036] It also includes a spring 8 , which is disposed in the sleeve 7 and sleeved on the breathing tube 5 . One end of the spring 8 abuts against the inner end of the sleeve 7 , and the other end abuts against the extrusion block 9 .

[0037] Preferably, a limiting end 701 is formed on one end of the sleeve 7 close to the extrusion block 9 .

[0038] In the initial state, the spring 8 is in a pre-compression state. At this time, the spring 8 reserves a small amount of elastic potential energy, which squeezes the squeezing block 9. Under the restriction of the limit end 701, the squeezing block 9 can be prevented from being separated from the sleeve 7, and the strip block 401 on the connecting tube 4 is ensured to be inserted into the first strip groove, and the squeezing block 9 is squeezed. When the strip block 401 slides to the end of the first strip groove, the elastic potential energy of the spring 8 is at its maximum value, controlling the rotation of the breathing tube 5 relative to the connecting tube 4. When the strip block 401 slides to the end of the second arc groove, the force on the breathing tube 5 is released. At this time, under the action of the spring 8, the squeezing strip block 401 slides into the third strip groove to achieve locking of the breathing tube 5 and the connecting tube 4, and can prevent the breathing tube 5 from being separated from the connecting tube 4.

[0039] Among them, when the breathing tube 5 is separated from the connecting tube 4, the breathing tube 5 can be controlled to move relative to the connecting tube 4, so that the strip block 401 is disengaged from the third strip groove, and then the breathing tube 5 is rotated, so that the strip block 401 passes through the second arc groove and rotates to the end of the first strip groove. At this time, the strip block 401 is controlled to move relative to the first strip groove to achieve the separation of the breathing tube 5 from the connecting tube 4.
