[0001] This utility model relates to the field of medical equipment, and in particular to a multifunctional adjustable oxygen bag. Background Technology

[0002] In the modern medical field, oxygen bags are widely used as an important oxygen supply device in various occasions. However, oxygen bags on the market currently have some problems that limit their convenience and reliability.

[0003] First, existing oxygen bags are generally large in size and have a smooth surface, lacking a good grip, which makes them inconvenient to carry. Whether it is medical staff making emergency calls or patients and their families during transport, they all face difficulties in carrying them.

[0004] Secondly, traditional oxygen bags also have drawbacks in the installation method of the inhalation tube. To facilitate the replacement of the inhalation tube, it is usually directly sleeved onto the outlet tube and secured by the pressure generated by its own elastic deformation. However, because the surface of the outlet tube is smooth, it is easy for the inhalation tube to fall off during daily use if it is accidentally touched or pulled by a slight external force, which will affect the normal use of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multifunctional adjustable oxygen bag, which aims to improve the problem that the oxygen bags in the prior art are large in size and inconvenient to grasp, thus making them difficult to carry.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional adjustable oxygen bag, comprising a bag body, an air outlet pipe provided on the left surface of the bag body, a pipe fixing assembly provided on the outer wall of the air outlet pipe, a length adjustment assembly provided on the lower surface of the bag body, a reinforcement assembly provided on the left surface of the bag body, the length adjustment assembly comprising an adjustment plate, a rotating shaft elastically connected to the inner wall of the adjustment plate by a torsion spring, one end of a carrying strap fixedly connected to the outer wall of the rotating shaft, and a gear fixedly connected to the left surface of the rotating shaft.

[0012] The reinforcement component includes a first strap, the right end of which is fixedly connected to the left surface of the bag body, and a second strap is fixedly connected to the right surface of the bag body. The back surface of the first strap is provided with Velcro.

[0013] As a further description of the above technical solution:

[0014] The rotating shaft is rotatably connected to the inner wall of the adjusting plate, one end of the torsion spring is fixedly connected to the upper surface of the rotating shaft, and the other end of the torsion spring is fixedly connected to the top of the inner wall of the adjusting plate.

[0015] As a further description of the above technical solution:

[0016] The upper surface of the adjustment plate is fixedly connected to the lower surface of the bag body, and the other end of the shoulder strap is fixedly connected to the upper surface of the bag body.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the length of the carrying strap can be flexibly adjusted by the length adjustment component to adapt to different groups of people, making it convenient for medical staff and patients to carry the oxygen bag on their back or chest.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1This utility model provides an embodiment of a multifunctional adjustable oxygen bag, including a bag body 1, which is the main body of the oxygen bag. The oxygen bag is made of nylon coated with rubber, which is tough, not easy to break, and has a sealing function. In some specific situations, the bag body 1 can be used as a pillow. An air outlet pipe 2 is provided on the left surface of the bag body 1, from which oxygen is discharged. A pipe fixing component is provided on the outer wall of the air outlet pipe 2, which can firmly fix the inhalation pipe 33. A length adjustment component is provided on the lower surface of the bag body 1, which can flexibly adjust the length of the carrying strap 44 to accommodate different people. A reinforcement component is provided on the left surface of the bag body 1, which can increase the stability of the bag body 1 when carried.

[0034] Reference Figure 1 , Figure 4 , Figure 5 The length adjustment assembly includes an adjustment plate 41. The inner wall of the adjustment plate 41 is elastically connected to a rotating shaft 43 via a torsion spring 42. One end of a shoulder strap 44 is fixedly connected to the outer wall of the rotating shaft 43. When the rotating shaft 43 rotates, it can tighten or loosen the shoulder strap 44. A gear 45 is fixedly connected to the left surface of the rotating shaft 43. The rotating shaft 43 and the gear 45 rotate synchronously. The length adjustment assembly also includes a round rod 48. A handwheel 49 is fixedly connected to the left surface of the round rod 48. A limit block 46 is elastically connected to the inner wall of the adjustment plate 41 via a compression spring 47. The limit block 46 can limit the gear 45. The torsion spring 42, rotating shaft 43, shoulder strap 44, gear 45, limit block 46, compression spring 47, round rod 48 and handwheel 49 are arranged in two sets, symmetrically distributed on the left and right sides of the center line of the adjustment plate 41.

[0035] Reference Figure 1 - Figure 2 The pipe fixing assembly includes a positioning ring 31, which is fixedly connected to the left end of the outer wall of the air outlet pipe 2. A limiting ring 32 is fixedly connected to the middle section of the outer wall of the positioning ring 31. An air intake pipe 33 is sleeved on the outer wall of the air outlet pipe 2. The positioning ring 31 and the limiting ring 32 can open the connection between the air intake pipe 33 and the air outlet pipe 2. Figure 2 As shown, the opening is the middle section, which can apply greater pressure to the inner wall of the inhalation tube 33, generating stronger friction and thus reducing the risk of accidental dislodgement.

[0036] Reference Figure 1 , Figure 3 The reinforcing component includes a first strap 51, the right end of which is fixedly connected to the left surface of the bag body 1. A second strap 52 is fixedly connected to the right surface of the bag body 1. A Velcro 53 is provided on the back surface of the first strap 51. There are two sets of Velcro 53, located on the back surface of the first strap 51 and the front surface of the second strap 52, respectively. The Velcro 53 on the back surface of the first strap 51 has a rough surface, while the Velcro 53 on the front surface of the second strap 52 has a smooth surface. The rough and smooth surfaces of the Velcro 53 can be bonded to each other.

[0037] Reference Figure 1 , Figure 4 , Figure 5 A rotating shaft 43 is rotatably connected to the inner wall of an adjusting plate 41. One end of a torsion spring 42 is fixedly connected to the upper surface of the rotating shaft 43, and the other end of the torsion spring 42 is fixedly connected to the top of the inner wall of the adjusting plate 41. When the rotating shaft 43 rotates, it will compress the torsion spring 42 to generate a reaction force. The upper surface of the adjusting plate 41 is fixedly connected to the lower surface of the bag body 1. The other end of the carrying strap 44 is fixedly connected to the upper surface of the bag body 1. The carrying strap 44 can wrap around the back of the bag body 1. A round rod 48 passes through and is slidably connected to the left surface of the adjusting plate 41. A limiting block 46 is inserted into the gap of a gear 45. The outer ring of the gear 45 is composed of multiple tooth blocks. The limiting block 46 is stuck between two tooth blocks. The rear surface of the limiting block 46 is set as an arc surface. The rear side of the upper surface of the limiting block 46 is set as an arc surface. The limiting block 46 is squeezed. The arc surface of 6, the limiting block 46 will move to the left and disengage from the gear 45 to release the limiting. However, since the gear 45 can only press against the arc surface of the limiting block 46 when it rotates in the forward direction, the limiting block 46 can provide a one-way limiting for the gear 45. When the gear 45 rotates in the forward direction, it will drive the rotating shaft 43 to rotate synchronously, thereby causing the strap 44 to be wound up. The right surface of the round rod 48 is fixedly connected to the left surface of the limiting block 46. Pulling the handwheel 49 can drive the round rod 48 and the limiting block 46 to move synchronously. One end of the compression spring 47 is fixedly connected to the left surface of the limiting block 46, and the other end of the compression spring 47 is fixedly connected to the inner wall on the left side of the adjusting plate 41. The limiting block 46 is slidably connected to the inner wall of the adjusting plate 41. When the limiting block 46 moves to the left, it will squeeze the compression spring 47 to generate a reaction force.

[0038] Working principle: When using this device, first pull the handwheel 49 to move the round rod 48 and the limiting block 46 to the left. The limiting block 46 will compress the spring 47, generating a reaction force and disengaging from the gear 45, releasing the limiting effect on the gear 45. At this time, the gear 45 can rotate in the opposite direction. Then, put your hand through the shoulder strap 44, driving the rotating shaft 43 and the gear 45 to rotate in the opposite direction, loosening the shoulder strap 44, thereby increasing the length of the shoulder strap 44, so that the bag 1 can be carried on the user's back or chest. When the rotating shaft 43 rotates... When the torsion spring 42 is compressed, a reaction force is generated. After the shoulder is properly seated, the handwheel 49 is released. The reaction force of the compressed spring 47 will push the limit block 46 to move to the right and engage with the gear 45, thus limiting the gear 45 in one direction. After the handwheel 49 is released, the reaction force of the torsion spring 42 will drive the rotating shaft 43 and the gear 45 to rotate. When the gear 45 rotates, it will limit the arc surface of the limit block 46, thereby causing the limit block 46 to move forward and disengage from the gear 45 to release the limit. The rotating shaft 43 and the gear 45 can then rotate in the forward direction to tighten the shoulder strap 44.

[0039] When fixing the inhalation tube 33, pull one end of the inhalation tube 33 open and put it on the outer wall of the outlet tube 2. When the connection is completed, the connection between the inhalation tube 33 and the outlet tube 2 will be opened due to the obstruction of the positioning ring 31 and the limiting ring 32, so that the inner wall of the inhalation tube 33 is subjected to greater pressure and generates stronger friction, which can prevent accidental disconnection.

[0040] After the shoulder strap 44 is fixed, the bag body 1 can be tied around the user's waist by the cooperation of the first strap 51, the second strap 52 and the Velcro 53. This can provide lateral restraint for the bag body 1, effectively preventing the bag body 1 from shaking when the user runs, and improving the stability of the bag body 1.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
