Description

Technical Field

[0001] This utility model relates to the field of oxygen connecting tube technology, specifically to an oxygen connecting tube for a breathing bag. Background Technology

[0002] A breathing bag is a simple yet effective artificial ventilation tool. It is mainly used to provide respiratory support to patients in emergency situations, especially when the patient is critically ill and intubation is not timely. The breathing bag can quickly provide the patient with a sufficient supply of oxygen and improve tissue hypoxia. The oxygen connection tube is used to connect to the breathing bag and serves as the oxygen flow path to ensure rapid oxygen movement.

[0003] In existing technologies, the connection between the breathing bag and the connecting tube is mostly fixed by a damped plug-in method. However, the oxygen output pressure will generate a large pressure at the moment of discharge, which can easily cause it to fall off. In some application scenarios that require high sealing and stability, such as intensive care units, ambulances or telemedicine transportation, the fall off of the oxygen tube may lead to the interruption of the patient's respiratory support, seriously affecting the stable supply of oxygen and the patient's safety, thus causing serious medical consequences. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen connector tube for a breathing bag, which solves the problem that the oxygen output pressure is high at the moment of discharge, which can easily cause the tube to fall off. In some applications that require high sealing and stability, such as intensive care units, ambulances, or telemedicine transport, the fall off of the oxygen tube may lead to the interruption of respiratory support for patients, seriously affecting the stable supply of oxygen and the safety of patients, and thus causing serious medical consequences.

[0005] This utility model provides the following technical solution: an oxygen connecting tube for a breathing bag, comprising a breathing bag body and a third connecting tube, wherein a sealing disc is fixedly connected to the end of the breathing bag body, and a second connecting tube communicating with the interior of the breathing bag body is fixedly connected to the outer wall of the sealing disc, the second connecting tube and the third connecting tube are located on the same plane, and a compression structure for limiting the third connecting tube is provided at the interval between the second connecting tube and the third connecting tube.

[0006] As a preferred embodiment of the above technical solution, the extrusion structure includes a second connecting disc fixedly connected to the end of the second connecting pipe. The outer wall of the second connecting disc is connected with a plurality of limiting screws in an annular array. Nuts are threaded onto the outer wall of the limiting screws. A first connecting disc is provided at the end of the second connecting pipe on one side of the second connecting disc. The first connecting disc is also threadedly connected to the plurality of limiting screws. A pressure-bearing part is provided at the interval between the second connecting disc and the first connecting disc to extrude the third connecting pipe.

[0007] As a preferred embodiment of the above technical solution, the pressure-bearing part includes a flexible extrusion ring located at the interval between the first connecting disc and the second connecting disc. The inner sidewall of the flexible extrusion ring is fixedly connected to a friction ring that increases friction. The outer sidewall of the flexible extrusion ring is symmetrically formed with a first inclined edge to facilitate pressure.

[0008] As a preferred embodiment of the above technical solution, a flexible chuck is fixedly sleeved at the end of the flexible extrusion ring away from the first connecting disc, a second inclined edge is formed at the end of the flexible chuck near the second connecting disc, and a third inclined edge is formed on the inner sidewall of the opposite end of the first and second connecting discs.

[0009] As a preferred embodiment of the above technical solution, the flexible chuck is slidably connected to the second connecting disc via the second inclined side and the third inclined side, and the first connecting disc is slidably connected to the flexible extrusion ring via the third inclined side and the first inclined side.

[0010] As a preferred embodiment of the above technical solution, a first connecting tube is fixedly connected to the end of the breathing bag body away from the sealing disc, and a connecting seat connected to the external oxygen exhaust end is fixedly connected to the end of the first connecting tube.

[0011] As a preferred embodiment of the above technical solution, the end of the third connecting pipe is formed with an access end, and the access end is inserted into the end of the second connecting pipe to form a sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, by incorporating a compression structure, during use, the rotating nut engages with the limiting screw. The limiting screw then moves linearly, compressing the flexible compression ring. Since the third connecting tube is inserted into the second connecting tube, the flexible compression ring, after being compressed, contracts inward, gradually compressing the third connecting tube. Furthermore, a friction ring is provided on the inner wall of the flexible compression ring to contact the outer wall of the access end, thereby increasing friction and preventing detachment. Regarding sealing, because the flexible compression ring is made of flexible material, the smaller the distance between the first and second connecting discs, the greater the compressive force exerted by the first and second connecting discs on the flexible compression ring. This method effectively prevents detachment between the second and third connecting tubes. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: an oxygen connecting tube for a breathing bag, including a breathing bag body 1 and a third connecting tube 15. A sealing disc 13 is fixedly connected to the end of the breathing bag body 1. A second connecting tube 14 communicating with the interior of the breathing bag body 1 is fixedly connected to the outer wall of the sealing disc 13. The second connecting tube 14 and the third connecting tube 15 are located on the same plane. A compression structure for limiting the third connecting tube 15 is provided at the interval between the second connecting tube 14 and the third connecting tube 15.

[0021] By adopting the above scheme, the design of the extrusion structure effectively restricts the position of the third connecting tube 15, preventing it from accidentally loosening or falling off during use, thereby enhancing the stability and reliability of the connection, ensuring the continuity and safety of oxygen transmission. The fixed connection of the sealing disc 13 not only strengthens the structural integrity of the breathing bag body 1, but also forms an efficient sealing channel with the inside of the breathing bag body 1 through the second connecting tube 14 fixedly connected to its outer wall, reducing the possibility of gas leakage and improving the overall airtightness and usage efficiency.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the extrusion structure includes a second connecting plate 21 fixedly connected to the end of the second connecting pipe 14. The outer wall of the second connecting plate 21 is connected with a plurality of limiting screws 23 in an annular array. Nuts 24 are threaded onto the outer wall of the limiting screws 23. The end of the second connecting pipe 14 is provided with a first connecting plate 2 on one side of the second connecting plate 21. The first connecting plate 2 and the plurality of limiting screws 23 are also connected by threads. A pressure-bearing part is provided at the interval between the second connecting plate 21 and the first connecting plate 2 to extrude pressure onto the third connecting pipe 15. The pressure-bearing part includes a flexible extrusion ring 22 located at the interval between the first connecting plate 2 and the second connecting plate 21. A friction ring 26 for increasing friction is fixedly connected to the inner wall of the flexible extrusion ring 22. The outer wall of the flexible extrusion ring 22 is symmetrically formed with a first inclined edge 221 to facilitate pressure.

[0023] By adopting the above scheme, the distance between the first connecting disc 2 and the second connecting disc 21 can be precisely adjusted through the threaded connection between the limiting screw 23 and the nut 24, thereby achieving fine adjustment of the compression degree of the flexible extrusion ring 22. This not only ensures that the third connecting tube 15 is stably extruded and fixed, but also allows the tightening force to be adjusted according to actual needs, avoiding problems caused by excessive tightness or looseness. When compressed, the flexible extrusion ring 22 can closely fit the outer wall of the third connecting tube 15 to form an effective sealing layer, reducing the risk of gas leakage. At the same time, the addition of the friction ring 26 further increases the friction of the contact surface, preventing the third connecting tube 15 from sliding or loosening under high pressure or vibration conditions. Since the flexible extrusion ring 22 has a certain degree of elasticity and plasticity, it can adapt to third connecting tubes 15 of different diameters and shapes, improving the versatility and adaptability of the extrusion structure.

[0024] like Figure 3 and Figure 4 As shown, a flexible chuck 25 is fixedly sleeved at the end of the flexible extrusion ring 22 away from the first connecting disc 2. A second inclined edge 251 is formed at the end of the flexible chuck 25 near the second connecting disc 21. A third inclined edge 27 is formed on the inner sidewall of the opposite end of the first connecting disc 2 and the second connecting disc 21. The flexible chuck 25 and the second connecting disc 21 are slidably connected through the second inclined edge 251 and through the third inclined edge 27. The first connecting disc 2 and the flexible extrusion ring 22 are slidably connected through the third inclined edge 27 and through the first inclined edge 221.

[0025] The above-mentioned design, with the sliding connection between the second inclined side 251 and the third inclined side 27, allows the flexible chuck 25 to slide into place more easily during assembly and form a stable contact with the second connecting plate 21. Similarly, the sliding connection between the third inclined side 27 of the first connecting plate 2 and the first inclined side 221 of the flexible extrusion ring 22 also promotes the smooth progress of the assembly process.

[0026] like Figure 1 and Figure 2As shown, the end of the breathing bag body 1 away from the sealing plate 13 is fixedly connected to a first connecting tube 11. The end of the first connecting tube 11 is fixedly connected to a connecting seat 12 connected to the external oxygen exhaust end. The end of the third connecting tube 15 forms an access end 151, which is inserted into the end of the second connecting tube 14 to form a sleeve.

[0027] By using the above solution, the access end 151 is inserted into the end of the second connecting pipe 14 through a socket connection, which can form a tight connection, effectively reducing the risk of gas leakage. This not only ensures a stable supply of oxygen but also improves the safety and reliability of the system.

[0028] Working principle: When connecting the second connecting pipe 14 and the third connecting pipe 15, the user inserts the end of the access end 151 into the interior of the second connecting pipe 14 and aligns the cuts of the second connecting pipe 14 and the third connecting pipe 15. Since the ends of the second connecting pipe 14, the third connecting pipe 15, and the access end 151 are all made of non-flexible materials, they can provide support and withstand pressure when connected. Then, the rotating nut 24 engages with the limiting screw 23. At this time, the limiting screw 23 will move linearly and compress the flexible compression ring 22. Because the third connecting pipe 15 is inserted into the interior of the second connecting pipe 14, the flexible compression ring 22 can contract inward after being compressed, gradually compressing the third connecting pipe 15. This results in the access end 151 and the third connecting pipe 15 being subject to corresponding pressure restrictions. The inner wall of 22 is also provided with a friction ring 26 that contacts the outer wall of the access end 151, thereby increasing friction and preventing detachment. As for the sealing problem, since the flexible compression ring 22 is made of flexible material, the smaller the distance between the first connecting plate 2 and the second connecting plate 21, the greater the extrusion force applied by the first connecting plate 2 and the second connecting plate 21 to the flexible compression ring 22. This method can prevent detachment between the second connecting pipe 14 and the third connecting pipe 15. During the compression of the flexible compression ring 22, a first inclined edge 221 is formed on the outer wall of the flexible compression ring 22, which cooperates with the third inclined edge 27 of the inner wall of the first connecting plate 2. Therefore, when the flexible compression ring 22 is compressed, the first connecting plate 2 presses the inclined surface of the first inclined edge 221 against the flexible compression ring 22, and the second connecting plate 21 also presses the flexible chuck 25 in the same way.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
