Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a portable small oxygen cylinder bag. Background Technology

[0002] Oxygen cylinders are among the most widely used and common medical devices in the medical field. They are an important tool for treating diseases such as difficulty breathing and hypoxemia. Initially, portable oxygen cylinders were large and inconvenient to carry. Later, with the advancement of materials science and compression technology, portable oxygen cylinder bags gradually developed into small, lightweight, and easy-to-carry products. However, existing oxygen cylinders still have the problem of being inconvenient to carry, especially when picking up patients from their homes. When patients need oxygen, medical staff have to carry the oxygen cylinder, which affects their ability to observe the patient's condition and administer medication. Moreover, when it is necessary to lift the patient onto a stretcher, there is no suitable place to put the oxygen cylinder, so medical staff have to carry it with them, especially when continuous oxygen infusion is required. This not only increases their burden but may also affect the smooth progress of the emergency procedure.

[0003] Therefore, there is an urgent need for a portable small oxygen cylinder bag to solve the problems existing in the current technology. Utility Model Content

[0004] In view of this, this utility model proposes a portable small oxygen cylinder bag, which aims to solve the problem of the inconvenience of carrying existing oxygen cylinders.

[0005] This utility model provides a portable small oxygen cylinder bag, comprising:

[0006] A slide rail is provided on one side of the stretcher body;

[0007] A fixing plate, wherein a groove is provided on one side of the fixing plate;

[0008] The side cylindrical wall is provided in two parts, and one end of each side cylindrical wall is fixed to the middle of the fixing plate.

[0009] The bottom cylindrical wall is connected to the rear part of the fixed plate and the two side cylindrical walls;

[0010] The fastening unit includes a fixed locking part and a sliding locking part. The fixed locking part is disposed on the fixed plate and located inside the two side cylinder walls. The sliding locking part is disposed on one side of the fixed locking part.

[0011] A locking unit is disposed on one side of the sliding locking part.

[0012] Furthermore, the fixing and locking part includes a fixing and locking plate and a fixing and locking tongue. One side of the fixing and locking plate is fixedly connected to the fixing plate, and the fixing and locking tongue is fixedly connected to the other side of the fixing and locking plate.

[0013] Furthermore, the fixing and locking part also includes a first limiting groove, and the fixing and locking plate is provided with a first limiting groove.

[0014] Furthermore, the fixing and locking plate is also provided with a threaded hole, and the threaded hole is located on one side of the first limiting groove.

[0015] Furthermore, the sliding locking part includes a sliding locking tongue and a first limiting block. One end of the sliding locking tongue is located in the first limiting groove. The first limiting block is fixedly connected to the sliding locking tongue, and the first limiting block is located in the first limiting groove.

[0016] Furthermore, the locking unit includes a second limiting block, a first locking block, and a first locking rod. The first locking block is fixedly connected to one end of the first locking rod, and the second limiting block is located at the other end of the first locking rod.

[0017] Furthermore, the fastening unit also includes a first through hole, of which there are two, located in the middle of the sliding locking tongue and the fixed locking tongue respectively.

[0018] Furthermore, it also includes shoulder straps, with both ends of the shoulder straps fixed to the upper and lower parts of the side cylindrical wall, respectively.

[0019] Furthermore, a first storage port is also provided on the side cylindrical wall.

[0020] Furthermore, it also includes a shock-absorbing part, which is disposed on the lower part of the side cylinder wall and the bottom cylinder wall.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a slide rail on the stretcher body, when it is necessary to fix the oxygen cylinder, simply slide the groove on the fixing plate into the slide rail. This not only facilitates the quick handling or fixing of the oxygen cylinder, but also improves the convenience and efficiency of operation. The slide rail and groove make the connection between the fixing plate and the stretcher body more stable, reducing the risk of the oxygen cylinder loosening or falling off during transportation, thereby improving patient safety.

[0031] See Figure 1-2 As shown, this embodiment provides a portable small oxygen cylinder bag, including: a slide rail, which is disposed on one side of the stretcher body 1;

[0032] Fixed plate 2, with a sliding groove 201 provided on one side;

[0033] There are two side cylinder walls 3, and one end of each side cylinder wall 3 is fixed to the middle of the fixing plate 2.

[0034] The bottom cylindrical wall 4 is connected to the rear and side cylindrical walls 3 of the fixing plate 2;

[0035] The fastening unit 5 includes a fixed locking part 510 and a sliding locking part 520. The fixed locking part 510 is disposed on the fixed plate 2 and located inside the two side cylinder walls 3. The sliding locking part 520 is disposed on one side of the fixed locking part 510.

[0036] Locking unit 6 is located on one side of the sliding locking part 520.

[0037] Specifically, a slide rail is provided on one side of the stretcher. When the patient lies on the stretcher, the patient's head is aligned with the position of the slide rail. When it is necessary to fix the oxygen cylinder, simply insert the oxygen cylinder into the space formed by the two side cylinder walls 3, and at the same time rotate the locking unit 6. The locking unit 6 drives the fastening unit 5 to fasten the oxygen cylinder, making it firmly fixed in the two side cylinder walls 3. At the same time, the oxygen cylinder can be fixed by sliding into the slide rail of the stretcher body 1 through the slide groove 201 on the fixing plate 2. The position of the oxygen cylinder is located at the patient's head position, which facilitates oxygen delivery during patient transport. Since the oxygen cylinder is fixed to the stretcher body 1, the oxygen cylinder and the stretcher body 1 can move synchronously.

[0038] Understandably, this embodiment improves patient comfort and safety during transport, especially for patients requiring oxygen. While traditional stretcher designs provide basic support, securing and facilitating medical equipment like oxygen cylinders is often a challenge in practical use. The oxygen cylinder is secured to the stretcher body 1 via the side wall 3, bottom wall 4, and fixing plate 2. The fastening unit 5 ensures the cylinder won't shift during transport, preventing shaking and collisions, avoiding potential damage or leakage, and ensuring the cylinder remains synchronized with the patient's head, guaranteeing continuous oxygen supply throughout the journey. The fastening unit 5 allows for adjustment of the cylinder's tightness or looseness as needed. The locking unit 6, with its sliding locking part 520, ensures the cylinder remains securely fixed and doesn't shift, which is crucial for the stability of oxygen cylinders in emergency situations. This ensures the cylinder remains in the correct position during transport, preventing any potential medical risks. The sliding groove 201 and rail make installing and removing the oxygen cylinder easier and faster. In emergency situations, time is of the essence. Using the slide rail and groove 201, medical personnel can quickly insert the oxygen cylinder into the space formed by the two side walls 3 and secure it rapidly with the locking unit 6. This not only reduces the time medical personnel spend operating the cylinder but also improves efficiency in emergency situations, especially in high-pressure or complex rescue scenarios. Operators can focus more on patient treatment without spending excessive time securing the equipment. This not only improves the safety and reliability of equipment securing but also reduces the operational difficulty for medical personnel. In traditional stretchers, securing oxygen cylinders or other medical equipment often requires multiple steps and external tools, or medical personnel holding the oxygen cylinder by hand. This is time-consuming and prone to errors for medical personnel in emergency situations. By simplifying the operation process, medical personnel can secure the oxygen cylinder in the simplest way, improving the overall efficiency of the rescue work. During emergency patient transport, especially for critically ill patients requiring continuous oxygen supply, the stability of the oxygen cylinder directly affects the treatment outcome. By securing the oxygen cylinder to the stretcher, it ensures synchronized movement between the cylinder and the stretcher body 1, preventing leaks or interruptions in oxygen supply due to external impacts or stretcher instability. The patient maintains a stable oxygen supply throughout the transport process, improving physiological stability. Simultaneously, the fastening unit 5 is highly flexible and adaptable, accommodating different types of stretchers and oxygen cylinders. Whether for intra-hospital transport or in field rescue environments, it guarantees the secure and synchronized movement of the oxygen cylinder.

[0039] In some embodiments of this application, the fixing locking part 510 includes a fixing locking plate 5101 and a fixing locking tongue 5102. One side of the fixing locking plate 5101 is fixedly connected to the fixing plate 2, and the fixing locking tongue 5102 is fixedly connected to the other side of the fixing locking plate 5101.

[0040] In some embodiments of this application, the fixing and locking part 510 further includes a first limiting groove 5103, and the fixing and locking plate 5101 is provided with the first limiting groove 5103.

[0041] Specifically, the fixed locking plate 5101 is fixedly connected to the fixed plate 2 at one end and to the fixed locking tongue 5102 at the other end. The fixed locking tongue 5102 is semi-circular and can fit against the outer surface of the oxygen cylinder, so as to achieve a more secure locking of the oxygen cylinder. The fixed locking plate 5101 is provided with a first limiting groove 5103, which is used to enable the sliding locking part 520 to slide and lock.

[0042] Understandably, the semi-circular shape of the locking tongue 5102 allows for a better fit against the outer surface of the oxygen cylinder. Since oxygen cylinders are typically cylindrical or similar in shape, the semi-circular structure of the locking tongue 5102 provides close contact with the cylinder's outer surface, resulting in a larger contact area and a more secure fixation. Compared to traditional fixing devices, this design reduces shaking or shifting of the oxygen cylinder during transport, avoiding the risk of loosening or falling off due to vibration or external impact. The tight cooperation between the locking plate 5101 and the locking tongue 5102 achieves a more robust locking effect. The locking tongue 5102 not only provides sufficient contact force but also works in conjunction with the locking plate 5101 to firmly secure the oxygen cylinder within the stretcher body 1, ensuring that the oxygen cylinder remains in a safe, immobile position during emergency transport. This prevents any loosening, falling off, or collision with other objects during transport, improving the safety of the oxygen cylinder. The secure fixation of the oxygen cylinder directly affects the stability of the patient's oxygen supply during transport. With the fixed locking part 510, the oxygen cylinder can move synchronously with the stretcher, avoiding displacement or instability of the oxygen cylinder's position, thus ensuring that the oxygen delivery effect of the oxygen cylinder is not affected throughout the entire transport process. This is crucial for critically ill patients requiring continuous oxygen supply, preventing interruptions in oxygen supply due to cylinder displacement during transport. Traditional fixing methods, due to their complex structure or improper operation, often result in the oxygen cylinder not being fully fixed or locked, increasing the risk of medical accidents. A clear structure and precise coordination reduce the error rate during operation. The combination design of the fixed locking tongue 5102 and the locking plate provides intuitive operational feedback, ensuring that every operation is completed flawlessly, reducing the operator's burden and improving the overall accuracy and efficiency of the operation. The first limiting groove 5103 ensures that the sliding locking part 520 can slide and lock on the basis of the fixed locking part 510, increasing the stability of the oxygen cylinder fixation and ensuring the correct position of the locking components during operation, preventing accidental displacement or loosening of the sliding locking part 520. The limiting groove serves as a guide and constraint, ensuring the efficient and stable operation of the entire locking mechanism and avoiding problems such as insufficient locking or incorrect positioning that may occur in traditional designs. The semi-circular design of the fixing locking tongue 5102 can adapt to the shape of oxygen cylinders of different sizes. Regardless of the diameter or surface shape of the oxygen cylinder, it can ensure a secure fixation. Compared to traditional fixing devices, the adaptability of the fixing locking tongue 5102 makes this design compatible with various models and specifications of oxygen cylinders, improving the applicability and flexibility of the equipment and adapting to changing emergency rescue environments.

[0043] In some embodiments of this application, the fixing locking plate 5101 is further provided with a threaded hole 5104, and the threaded hole 5104 is located on one side of the first limiting groove 5103.

[0044] Specifically, the fixed locking plate 5101 has a threaded hole 5104 on its side. The threaded hole 5104 passes through the fixed locking plate 5101 and is connected to the first limiting groove 5103. The threaded hole 5104 is used for the insertion of the locking unit 6.

[0045] Understandably, the threaded hole 5104 allows the locking plate 5101 to engage more effectively with the locking unit 6. In traditional fixing methods, the stability and firmness of the locking components typically rely on simple insertion or pressing between parts. However, with the engagement of the threaded hole 5104, the locking unit 6 can be more firmly fixed by rotation. This threaded connection provides a more stable connection, preventing loosening, misalignment, or failure of the fixing and locking device under vibration or external impact. The threaded hole 5104 allows for higher precision in the insertion and rotation of the locking unit 6. When the locking unit 6 is inserted and rotated through the threaded hole 5104, it ensures that the oxygen cylinder is fixed in the set position, preventing movement of the oxygen cylinder due to loosening or insufficient locking of the fixing device, thereby ensuring the stability of oxygen supply to the patient during transport. The threaded hole 5104 increases the reliability of the fixing device, especially in high-load, strong-vibration environments, as the firmness of the threaded connection avoids the loosening or detachment problems that may occur with traditional plug-in methods. Mechanical locking makes the fixing device more stable and durable, reducing the risk of oxygen cylinders accidentally shifting or falling during transportation due to equipment failure, thereby improving the safety of the transportation process.

[0046] In some embodiments of this application, see Figure 3 As shown, the sliding locking part 520 includes a sliding locking tongue 5201 and a first limiting block 5202. One end of the sliding locking tongue 5201 is located in the first limiting groove 5103. The first limiting block 5202 is fixedly connected to the sliding locking tongue 5201 and is located in the first limiting groove 5103.

[0047] Specifically, a first limiting block 5202 is fixed on one end of the sliding locking tongue 5201, and the end with the first limiting block 5202 is set in the first limiting groove 5103. The first limiting groove 5103 is used to limit the displacement range of the first limiting block 5202, thereby limiting the displacement range of the sliding locking tongue 5201. By moving the sliding locking tongue 5201, the locking or loosening state of the oxygen cylinder can be achieved.

[0048] Understandably, the movement of the sliding locking tongue 5201, limited by the first limiting block 5202, controls the fixing or loosening of the oxygen cylinder, thus solving the problems of loosening, sliding, and instability that may occur during the transport of the oxygen cylinder. The sliding locking tongue 5201 can adjust its position as needed to achieve the tightening or loosening of the oxygen cylinder. The setting of the first limiting block 5202 restricts the displacement range of the sliding locking tongue 5201, ensuring that the sliding locking tongue 5201 can only move within a limited range. This avoids improper locking or loosening caused by excessive movement of the sliding locking tongue 5201, thus ensuring that the oxygen cylinder can be firmly fixed on the stretcher. The first limiting groove 5103 limits the displacement range of the first limiting block 5202, further improving the control accuracy of the locking process. The existence of the limiting groove controls the movement of the sliding locking tongue 5201, thus preventing the sliding locking tongue 5201 from stopping in an inappropriate position, ensuring that the oxygen cylinder is always in a safe and stable state when locked. The precise fit between the limiting groove and the first limiting block 5202 ensures a more reliable locking process, preventing loosening and positional displacement. Traditional oxygen cylinder securing systems carry the risk of locking failure due to instability or inaccurate positioning of the locking device. The combined design of the sliding locking tongue 5201 with the first limiting block 5202 and the first limiting groove 5103 reduces this risk by clearly limiting the displacement of the sliding locking tongue 5201. Each operation ensures the oxygen cylinder is firmly fixed in the designated position after locking, improving the overall structural stability and safety. The sliding locking tongue 5201 simplifies locking and releasing the oxygen cylinder. Medical personnel can quickly secure or release the oxygen cylinder by simply sliding the locking tongue 5201. The first limiting block 5202 ensures a smooth locking process, avoiding complex manual adjustments or multi-step operations, making oxygen cylinder securing and releasing more efficient and convenient. Especially in emergencies, this reduces the time spent by operators during emergency treatment and improves reaction speed.

[0049] In some embodiments of this application, the locking unit 6 includes a second limiting block 610, a first locking block 620 and a first locking rod 630. The first locking block 620 is fixedly connected to one end of the first locking rod 630, and the second limiting block 610 is located at the other end of the first locking rod 630.

[0050] Specifically, the second limiting block 610 is fixedly connected to one end of the first locking rod 630, and the first locking block 620 is sleeved on the other end of the first locking rod 630. The first locking rod 630 of the locking unit 6 passes through the threaded hole 5104 and enters the first limiting groove 5103. By rotating the second limiting block 610, the first locking rod 630 is displaced, and then the first locking block 620 on the first locking rod 630 pushes the sliding locking part 520 to move, thereby realizing the locking or releasing function of the oxygen cylinder.

[0051] Understandably, the cooperation between the first locking rod 630 and the second limiting block 610 provides precise control, enabling the oxygen cylinder to be locked or released when the first locking rod 630 is displaced by rotating the second limiting block 610. The first locking block 620, sleeved on the other end of the first locking rod 630, further ensures the accuracy of the locking process. Each operation ensures that the oxygen cylinder is fixed without error, thus preventing positional shifts or loosening during transport. The interaction between the first locking rod 630 and the second limiting block 610 through the threaded hole 5104 and the first limiting groove 5103 ensures that the first locking rod 630 can stably enter the limiting groove without slippage or misalignment during operation. The function of the second limiting block 610 is to push the first locking rod 630 to the correct locking position, thereby ensuring that the oxygen cylinder is firmly fixed in the designated position, improving the overall locking stability and preventing fixing failure due to external vibration or impact. The first locking block 620, connected to the first locking rod 630, applies pressure to fix the sliding locking part 520 in the desired position. During the rotation of the second limiting block 610, the first locking block 620 pushes the sliding locking part 520 to move and secure the oxygen cylinder, thus preventing the oxygen cylinder from loosening or falling off during transport due to unstable locking. By integrating the first locking block 620, the first locking rod 630, and the second limiting block 610 into a single unit, the entire locking process becomes simpler. Simply rotating the second limiting block 610 displaces the first locking rod 630, thereby moving the locking unit 6 and locking or releasing the oxygen cylinder. Medical personnel do not need to perform cumbersome steps; a simple rotation operation is sufficient to secure the oxygen cylinder. This simplified operation is ideal for emergency situations, saving operators valuable time and improving work efficiency. Traditional locking methods often require complex adjustments and operations, easily leading to misoperation or incomplete locking. The cooperation of the threaded hole 5104, the first limiting groove 5103, the second limiting block 610, and the first locking rod 630 makes the entire operation process more intuitive and easier to control. The movement of the sliding locking part 520 is restricted, reducing the likelihood of incomplete locking or failure to secure the system during use, lowering the risk of misoperation, and improving system reliability. Time is often extremely valuable during patient transport. The locking unit 6 allows operators to quickly secure or release the oxygen cylinder, avoiding wasted time due to cumbersome operations in emergencies. Especially during resuscitation, the rapid response of the oxygen cylinder securing system ensures uninterrupted oxygen supply to the patient, maximizing patient safety.

[0052] In some embodiments of this application, the fastening unit 5 further includes a first through hole 530. There are two first through holes 530, which are located in the middle of the sliding locking tongue 5201 and the fixed locking tongue 5102, respectively.

[0053] Understandably, the first through hole 530 is located in the middle of the sliding locking tongue 5201 and the fixed locking tongue 5102, increasing the structural stability between them. By providing a through hole in the middle of the tongue, the rigidity of the structure is strengthened. When subjected to external forces (such as impacts, vibrations, etc.), the entire fastening unit 5 can better withstand these external impacts, avoiding structural distortion or component loosening due to uneven force distribution. In traditional designs, the force on components is relatively concentrated, which may lead to excessive impact on a single part, causing localized damage. However, by providing two first through holes 530, the external impact force and pressure can be dispersed, distributing the force evenly to different areas of the locking tongue. This uniform force distribution not only improves the structure's impact resistance but also avoids the risk of localized damage, enhancing the long-term stability of the equipment. Adding a through hole in the middle reduces the risk of fatigue damage caused by uneven force distribution on the locking tongue. Long-term repeated use can lead to fatigue cracks in localized areas. The first through-hole 530 helps alleviate this stress concentration, extending the lifespan of the tongue. By optimizing force transmission, it prevents structural breakage or deformation caused by repeated movement and use, thus extending the equipment's service life. The first through-hole 530 allows the sliding locking tongue 5201 and the fixed locking tongue 5102 to operate under more precise force conditions. In practical applications, by providing a through-hole in the middle of the locking tongue, the locking tongue can maintain more precise positioning and displacement control during the locking process. The presence of the through-hole ensures more uniform force transmission during locking, preventing fixing failure or loosening due to the locking tongue losing precise positioning. This makes the entire locking process more reliable, avoiding errors or instability during operation.

[0054] In some embodiments of this application, see Figure 4 As shown, it also includes a shoulder strap 7, with its two ends fixed to the upper and lower parts of the side cylindrical wall 3, respectively.

[0055] In some embodiments of this application, a first storage port 8 is also provided on the side cylindrical wall 3.

[0056] Specifically, in some cases, it is not suitable to place oxygen cylinders on stretchers. In such cases, medical staff can carry oxygen cylinders on their backs with their hands free to perform relocation or rescue work. At the same time, a first storage port 8 is provided on the side wall 3, in which rescue equipment such as oxygen tubes can be placed.

[0057] Understandably, by attaching shoulder straps 7 to the upper and lower parts of the side cylinder wall 3, the oxygen cylinder can be moved like a backpack, greatly facilitating medical personnel during emergency rescue. When the oxygen cylinder is unsuitable for placement on a stretcher, medical personnel can use the shoulder straps 7 to carry it on their back, freeing their hands and enabling them to better treat, transport, or perform other emergency procedures. Freeing their hands allows medical personnel to handle various emergencies in tense and complex rescue environments, improving operational efficiency and reaction speed. In many emergency rescue scenarios, medical personnel need to handle multiple tasks simultaneously, such as ensuring the patient's breathing, monitoring heartbeat, or performing necessary emergency procedures. Using the shoulder straps 7 to carry the oxygen cylinder allows for a stable oxygen supply at any time without interfering with other operations, enabling medical personnel to perform procedures while ensuring the patient's oxygen needs are met, thus optimizing the overall rescue process. The backpack-style design of the oxygen cylinder avoids the accumulation and clutter of oxygen cylinders and other rescue tools, improving the efficiency of item use and ease of operation, and enhancing their mobility. In scenarios requiring rapid traversal of complex environments, staircases, and confined spaces, the flexibility offered by backpack oxygen cylinders is crucial. Unlike traditional trolley-style or stretcher-mounted oxygen cylinders, backpack oxygen cylinders allow medical personnel to move freely in more congested spaces, quickly transferring patients or providing emergency treatment. In emergency situations, flexibility and mobility directly impact the success of the rescue, thus enhancing emergency response capabilities. By incorporating shoulder straps 7 on the side wall 3 and securing them to the top and bottom ends of the wall, the stability of the oxygen cylinder during backpack carrying is ensured. The fixed positions of the shoulder straps 7 prevent the oxygen cylinder from tilting or swaying during movement, which is essential for rapid movement in various environments. A stable carrying method ensures the oxygen cylinder remains in the intended position, preventing tilting due to unstable placement and avoiding the risk of leakage or damage. The backpack design, through the shoulder straps 7, distributes the weight of the oxygen cylinder evenly across the shoulders and back, reducing pressure on any single area of ​​the medical personnel. Compared to traditional hand-carrying methods, the back-carrying method effectively reduces the burden on the shoulders and wrists of operators, avoiding discomfort or fatigue caused by carrying oxygen cylinders for extended periods. Especially during long-duration rescue operations, distributing the load ensures that medical personnel maintain high physical strength and energy, preventing excessive fatigue from affecting the quality of the rescue.

[0058] In some embodiments of this application, a shock-absorbing part 9 is also included, which is disposed at the lower part of the side cylinder wall 3 and the bottom cylinder wall 4.

[0059] Understandably, stability, durability, convenience, and comfort are crucial factors in medical rescue, especially in the transportation and carrying of critical first-aid equipment such as oxygen cylinders. As part of first-aid equipment, oxygen cylinders often need to be handled on uneven ground and in harsh environments. In such situations, the shock-absorbing unit 9 is particularly important. Located in the lower part of the side cylinder wall 3 and the bottom cylinder wall 4, the shock-absorbing unit 9's main function is to absorb and mitigate external vibrations and impacts, ensuring the stability of the oxygen cylinder during transportation and preventing damage, leakage, or improper operation due to vibration and impact, thus further ensuring the safety and effectiveness of the equipment. The shock-absorbing unit 9 first absorbs external impacts and vibrations, especially when handling oxygen cylinders on complex and uneven ground. During emergency rescue, oxygen cylinders often need to be moved in different environments, including corridors, stairs, and bumpy roads. Without shock-absorbing measures, oxygen cylinders may be subjected to impacts from the ground, potentially leading to equipment damage or gas leakage due to collisions. Through its structural design, the shock-absorbing unit 9 mitigates these impacts, ensuring stable operation of the oxygen cylinder in different environments and reducing the potential risk of damage due to vibration. Oxygen cylinders are high-pressure containers carrying gas, and their structure is relatively fragile. Excessive vibration or impact during transportation can damage the cylinder body, cause leakage at the valve opening, or even lead to complete rupture. The shock-absorbing unit 9, through its shock-absorbing materials and structural design, effectively disperses or absorbs vibration and impact energy, thereby reducing the likelihood of damage during use and transportation. Leakage from high-pressure oxygen cylinders has always been a significant safety hazard in the use of emergency equipment. Because the gas inside the cylinder is under high pressure, any external impact or vibration can cause cracks in the cylinder body, loosening of the valve, or damage to other components, leading to leakage. The shock-absorbing unit 9 effectively absorbs and isolates vibrations, reducing the risk of cylinder leakage and improving the safety of the equipment.

[0060] The portable small oxygen cylinder bag in the above embodiments features a slide rail on the stretcher body. When the oxygen cylinder needs to be secured, simply slide the groove on the fixing plate into the slide rail. This not only facilitates quick retrieval or securing of the oxygen cylinder but also improves the convenience and efficiency of the operation. The slide rail and groove make the connection between the fixing plate and the stretcher body more stable, reducing the risk of the oxygen cylinder loosening or falling off during transport, thereby improving patient safety. Furthermore, when the oxygen cylinder is inserted into the side wall, the fastening unit and locking unit work together to lock the oxygen cylinder. By rotating the locking unit, the fastening unit can be adjusted to tighten or loosen, ensuring the oxygen cylinder is firmly secured under different conditions. This simplifies the process of securing and releasing the oxygen cylinder, reduces the burden on medical staff, and the combination of the fastening and locking units allows for multi-point fixation of the oxygen cylinder, further enhancing the fixation effect.
