Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oxygen bag regulation, and particularly relates to an oxygen bag regulation device. Background Art
[0002] An oxygen bag is a bag for storing oxygen, mainly made of non-toxic and non-harmful chemical materials. The oxygen bag is convenient to carry and operate, and can be used for home care or for first aid transportation by medical units when going out. The biggest and most significant features of a medical oxygen bag are its light weight, easy portability, and easy storage. It is widely used in pre-hospital first aid, patient transfer, and primary medical institutions. It is usually blue. Medical oxygen bags used in hospitals and first aid centers (stations) at all levels in China are made of three different materials: metal foil composite, rubber nylon cloth, and canvas. The attached oxygen switch, i.e., the regulator, cannot effectively regulate and control the output flow.
[0003] During oxygen supply of an ordinary oxygen bag, the pressure continuously drops, and medical staff need to press the oxygen bag manually, which is laborious and time-consuming. An oxygen bag regulation device is used to regulate the internal pressure of the oxygen bag, thus facilitating the operation of medical staff, enabling medical personnel not to always press the oxygen bag, and achieving the purpose of labor saving. The existing oxygen bag regulation devices have simple structures and single functions. When the oxygen inside the oxygen bag is exhausted, they cannot give an alarm, which is not convenient for reminding medical staff to replace the oxygen bag in time, resulting in poor practicability.

The present utility model provides the following embodiments.
[0026] Please refer to Figures 1-5, An embodiment provided by the present utility model: An oxygen bag adjusting device, including a protective box 1, openings are provided at the bottom and one side of the protective box 1, a winding assembly is arranged inside the protective box 1, a bag body 2 is wound around the outside of the winding assembly, the winding assembly includes a central shaft 5, a disc spring 6 and a rotating cylinder 7, a central shaft 5 is arranged at the center of the protective box 1, a disc spring 6 is arranged on the outside of the central shaft 5, the center line of the disc spring 6 coincides with the center line of the central shaft 5, a rotating cylinder 7 is arranged on the outside of the disc spring 6, and both ends of the disc spring 6 are fixedly connected to the central shaft 5 and the rotating cylinder 7 respectively. Limiting rings 8 for limiting the winding of the bag body 2 are arranged on both sides of the rotating cylinder 7, and the limiting rings 8 are fixedly connected to the central shaft 5. Both ends of the rotating cylinder 7 are respectively in contact with one side of the two limiting rings 8. Through the winding force of the disc spring 6, the rotating cylinder 7 rotates about the central shaft 5, and the used part of the bag body 2 can be wound up, reducing the capacity of the bag body 2, achieving the purpose of adjusting the pressure inside the bag body 2, so that when using the oxygen bag to supply oxygen, there is no need to manually press the oxygen bag. The setting of the limiting ring 8 can play a role in limiting when winding the bag body 2.
[0027] In this embodiment, the bag body 2 passes through the opening at the bottom of the protective box 1, a connector 3 for connecting the bag body 2 to the air supply pipe is arranged at the end of the bag body 2, push-button alarms 4 are arranged on both sides of the connector 3, and an alarm button is arranged on the side of the push-button alarm 4 close to the protective box 1. When the oxygen in the bag body 2 is exhausted, the empty bag body 2 is wound up by the winding assembly, so that the connector 3 at the end of the bag body 2 moves towards the protective box 1. When the connector 3 approaches the protective box 1, the device at the bottom of the protective box 1 can squeeze the alarm button of the push-button alarm 4, thereby realizing the alarm function, facilitating reminding the medical staff to replace the oxygen bag in time, and improving the practicability of the device.
[0028] In this embodiment, a box cover 9 is arranged at the opening on one side of the protective box 1, the side surface of the box cover 9 is in contact with the side surface of the protective box 1, and the central shaft 5 passes through the box cover 9 and the protective box 1. Locking nuts 10 for fixing the box cover 9 and the protective box 1 are threadedly connected to both ends of the central shaft 5. Loosening the locking nuts 10 can open the box cover 9, facilitating the replacement of the internal bag body 2, realizing the replacement of the oxygen bag. Through the combined use of the protective box 1 and the box cover 9, the collected bag body 2 can be protected, preventing the bag body 2 from being worn by external devices, and improving the protection performance of the device.
[0029] In this embodiment, one side of the opening at the bottom of the protective box 1 is fixedly connected with a fixed plate 11. The opening at the bottom of the protective box 1 can squeeze the passing bag body 2 to adjust the pressure inside the bag body 2. On the other side of the opening at the bottom of the protective box 1, there is a movable clamping plate 12 for squeezing the bag body 2. Both ends of the movable clamping plate 12 are fixedly connected with telescopic rods 13. The telescopic rods 13 are fixedly connected to the protective box 1. A spring 14 is sleeved outside the telescopic rods 13. The two ends of the spring 14 are fixedly connected to the movable clamping plate 12 and the protective box 1 respectively. The top surface of the movable clamping plate 12 is in contact with the bottom surface of the protective box 1. The inner diameter of the spring 14 matches the outer diameter of the telescopic rod 13. A hanging strap 15 is fixedly connected to the top of the protective box 1. By using the spring 14 and the telescopic rod 13, in cooperation with the fixed plate 11 and the movable clamping plate 12, the bag body 2 can be squeezed. At the same time, due to the winding force of the spiral spring 6, the rotating cylinder 7 rotates about the central axis 5, and the part of the bag body 2 where the oxygen is used up can be wound up, reducing the capacity of the bag body 2, so as to achieve the purpose of further adjusting the pressure inside the bag body 2.
[0030] Working principle: When using this device, first, the device can be picked up through the hanging strap 15, which is convenient for the user to pick up the device and also convenient for the user to hang the device during use. The bag body 2 is provided to store oxygen. The connector 3 can be used to connect this device to the external gas pipeline, facilitating the delivery of the oxygen in the bag body 2 to the patient. By using the spring 14 and the telescopic rod 13, in cooperation with the fixed plate 11 and the movable clamping plate 12, the bag body 2 can be squeezed. At the same time, due to the winding force of the spiral spring 6, the rotating cylinder 7 rotates about the central axis 5, and the part of the bag body 2 where the oxygen is used up can be wound up, reducing the capacity of the bag body 2, so as to achieve the purpose of adjusting the pressure inside the bag body 2, making it unnecessary for manual pressing of the oxygen bag when using the oxygen bag for oxygen supply. The setting of the limit ring 8 can play a role in limiting during the winding of the bag body 2, preventing the bag body 2 from shifting during winding. When the oxygen in the bag body 2 is exhausted, the empty bag body 2 is wound up by the winding component, causing the connector 3 at the end of the bag body 2 to move towards the protective box 1. When the connector 3 approaches the protective box 1, the device at the bottom of the protective box 1 can squeeze the alarm button of the push-button alarm 4, thereby realizing the alarm function, facilitating the reminder for medical staff to replace the oxygen bag in time and improving the practicability of this device. Loosen the locking nut 10, and the box cover 9 can be opened to facilitate the replacement of the internal bag body 2, realizing the replacement of the oxygen bag. Through the combined use of the protective box 1 and the box cover 9, the collected bag body 2 can be protected, preventing the bag body 2 from being worn by external devices and improving the protection performance of this device.
