Description

Technical Field

[0001] This invention relates to the field of constant pressure oxygen delivery via oxygen bags, specifically a constant pressure oxygen supply device for patients with respiratory failure that is convenient for imaging examinations. Background Technology

[0002] Patients with respiratory failure in the emergency room require imaging to identify the lesions, such as CT scans. However, metal is not allowed during CT scans as it would interfere with the examination. Yet, these critically ill patients cannot live without oxygen; therefore, oxygen bags are often used for oxygen supply, allowing them to be isolated from metal. The oxygen supply in these bags is regulated, decreasing with use and causing a drop in pressure, which can affect the patient's breathing. Therefore, maintaining the correct pressure in the oxygen bags during use is a pressing issue for professionals in this field. Summary of the Invention

[0003] The purpose of this invention is to provide a constant pressure oxygen supply device for patients with respiratory failure that is convenient for imaging examinations, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a constant pressure oxygen supply device for respiratory failure patients that facilitates imaging examinations, comprising two soft oxygen bags, which can be made of transparent plastic or other flexible, bendable forms. The lower ends of the two oxygen bags are connected by an oxygen supply tube, and the oxygen supply tube is equipped with a connector for filling with oxygen. The upper side of the oxygen bags is wound around a gravity-supporting roller, and the two rollers are connected by a synchronization mechanism for synchronous rotation. The invention also includes a winding mechanism that drives the rollers to rotate. Under the action of gravity, the rollers rotate and wind the oxygen bags along the winding mechanism. The rollers can provide counterweights. As oxygen is consumed, they move downwards under the action of gravity. When the winding mechanism moves the rollers downwards, it rotates, winding the oxygen bags and compressing them, thus squeezing the oxygen to the lower side, thereby ensuring oxygen supply pressure. Because gravity is constant, the resulting compression force is relatively stable, and the oxygen supply pressure is also relatively stable, ensuring stable oxygen supply pressure. The weight of the scroll can be adjusted as needed; for example, it can be made of solid plastic, and the weight can be set according to the requirements.

[0005] Preferably, the synchronization mechanism includes gears installed at the front and rear ends of the reels, with the left and right gears meshing to rotate synchronously. The two reels are connected via a connecting plate after passing through the gears on the same side. The connecting plate is rotatably connected to the reels. The connecting plate ensures that the two gears do not slide relative to each other, maintaining their relative positions and ensuring proper engagement.

[0006] Preferably, the winding mechanism includes pull ropes wound around the front and rear ends of the reel, with the inner ends of the pull ropes fixedly connected to the reel. The ends of the four pull ropes are connected by hooks, and the pull ropes are located between the oxygen bag and the gear. The four pull ropes ensure the overall stability and balance, and the hooks facilitate the movement of the whole. The left pull rope is wound counterclockwise around the reel, and the right pull rope is wound clockwise around the reel. In this way, the free ends of the pull ropes on both sides pass upward between the two reels. During winding, the two oxygen bags will contact and compress each other, improving the exhaust effect, which is better than winding from the outside and is less likely to cause the two oxygen bags to separate.

[0007] Preferably, it also includes a protective mechanism to prevent the pull rope from shifting, as the pull rope may shift towards the center, and the protective mechanism can prevent the shift.

[0008] Preferably, the protective mechanism includes a disc-shaped protective sleeve fitted over the outside of the pull rope, and the protective sleeve is rotatably connected to the reel. The protective sleeve has a rope hole for the pull rope to pass through upwards. The protective sleeve houses the pull rope, thus preventing friction between the pull rope and the oxygen supply bag.

[0009] Preferably, the diameter of the pull rope is consistent with the front and rear width of the inner cavity of the protective sleeve. This is mainly to ensure that the pull rope is concentrically wound without tilting during winding, so that the winding and unwinding lengths of the four pull ropes are consistent, ensuring balance and preventing tilting.

[0010] Preferably, it also includes a squeezing mechanism disposed between the upper ends of the two oxygen bags to squeeze out the oxygen inside the oxygen bags. Normally, the oxygen is also discharged when the roll is wound. However, the oxygen is not discharged completely at the beginning. As it is wound, the oxygen on the roll is continuously and completely discharged. The squeezing mechanism can accelerate the discharge of oxygen and ensure that the roll is wound with oxygen bags that have been discharged, making it more compact.

[0011] Preferably, the compression mechanism includes a counterweight block disposed between the two oxygen bags, and the counterweight block has a "T"-shaped cross-section to compress the oxygen bags by being held between the two rollers. Here it is "T"-shaped, but it could also be triangular, with the two sides forming arcs that overlap the upper sides of the rollers, and the middle section facilitating insertion between the two rollers, where the counterweight block is located.

[0012] Preferably, it also includes an anti-detachment mechanism disposed between the protective sleeve and the counterweight to prevent the counterweight from falling off.

[0013] Preferably, the anti-detachment mechanism includes a guide plate fixed between the left and right protective sleeves, and a vertical guide groove is provided in the middle of the guide plate. The front and rear ends of the counterweight are fixed with "T"-shaped sliders that match the guide grooves. The sliders can slide and guide within the guide grooves, ensuring the smooth movement of the counterweight.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. As oxygen is consumed, the roller moves downward under gravity, squeezing the oxygen bag. This pressure is maintained by utilizing gravity to ensure the pressure of the oxygen bag. The roller, oxygen bag, and gears are all made of non-metallic materials to facilitate inspection.

[0016] 2. A pull rope is wound on the reel. When the reel moves down, it will rotate and wind up the oxygen bag. This winds up the oxygen bag that has been venting gas, ensuring pressure and preventing it from accumulating. At the same time, it also reduces the space occupied.

[0017] 3. The counterweight can accelerate the expulsion of oxygen, thus allowing it to be wound better onto the spool;

[0018] 4. When filling the oxygen bag with oxygen, connect the connector, the oxygen bag will inflate, pushing the roller to rotate and unwind until it returns to the initial position. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 7This invention provides a technical solution for a constant pressure oxygen supply device for patients with respiratory failure that facilitates imaging examinations: A constant pressure oxygen supply device for patients with respiratory failure that facilitates imaging examinations includes two soft oxygen bags 1, which can be made of transparent plastic or other flexible materials that can be bent and rolled up. The cross-section of the oxygen bag 1 can be semi-circular to facilitate close contact at the near ends. The lower ends of the two oxygen bags 1 are connected by an oxygen supply tube 2, which is Y-shaped to facilitate bringing the two oxygen bags 1 together. The oxygen supply tube 2 is provided with a connector 3 for filling with oxygen. At the same time, an oxygen supply switch is provided on the oxygen supply tube 2. The upper side of the oxygen bag 1 is wound on a gravity-providing roller 4. The two rollers 4 are connected by a synchronization mechanism to rotate synchronously. The device also includes a winding mechanism that drives the rollers 4 to rotate. Under the action of gravity, the rollers 4 rotate and wind the oxygen bag 1 along the winding mechanism. The spool 4 provides counterweight. As oxygen is consumed, it moves downwards under gravity. The winding mechanism rotates as the spool 4 moves downwards, winding around the oxygen bag 1 and compressing it to push the oxygen to the lower side, thus maintaining oxygen delivery pressure. Because gravity is constant, the resulting compression force is relatively stable, leading to a stable oxygen delivery pressure. The weight of the spool 4 can be adjusted as needed; for example, it can be made of solid plastic, and the weight can be set according to requirements.

[0029] The synchronization mechanism includes gears 5 installed at the front and rear ends of the spool 4. The two gears 5 mesh with each other to rotate synchronously, and the two spools 4 are connected by a connecting plate 6 after passing through the gears 5 on the same side. The connecting plate 6 is rotatably connected to the spool 4. The connecting plate 6 ensures that the two gears 5 do not slide back and forth relative to each other, ensuring their relative position and proper engagement.

[0030] The winding mechanism includes pull ropes 7 wound around the front and rear ends of the reel 4, with the inner ends of the pull ropes 7 fixedly connected to the reel 4. The ends of the four pull ropes 7 are connected by hooks 8, and the pull ropes 7 are located between the oxygen bag 1 and the gear 5. The four pull ropes 7 ensure the overall stability and balance, and the hooks 8 facilitate the movement of the whole. The left pull rope is wound counterclockwise around the reel 4, and the right pull rope 7 is wound clockwise around the reel 4. In this way, the free ends of the pull ropes 7 on both sides pass upward between the two reels 4. During winding, the two oxygen bags 1 will come into contact and squeeze each other, improving the exhaust effect, which is better than winding from the outside and is less likely to cause the two oxygen bags 1 to separate.

[0031] It also includes a protective mechanism to prevent the pull rope 7 from shifting, as the pull rope 7 may shift towards the center. The protective mechanism includes a disc-shaped protective sleeve 9 that fits over the outside of the pull rope 7, and the protective sleeve 9 is rotatably connected to the roller 4. The protective sleeve 9 has a rope hole for the pull rope 7 to pass through upwards. The protective sleeve 9 houses the pull rope 7, so that the pull rope 7 will not rub against the oxygen bag 1. The diameter of the pull rope 7 is consistent with the front and back width of the inner cavity of the protective sleeve 9. This is mainly to ensure that the pull rope 7 is concentrically wound without tilting during winding, so that the winding and unwinding lengths of the four pull ropes 7 are consistent, ensuring balance and preventing tilting.

[0032] It also includes a compression mechanism positioned between the upper ends of the two oxygen bags 1 to expel oxygen from the bags. Normally, oxygen is also expelled during the winding of the roller 4, but initially, the oxygen is not completely expelled. As the roller winds, the oxygen on the roller 4 is gradually and completely expelled. The compression mechanism accelerates the expulsion of oxygen, ensuring that the roller 4 winds only oxygen-expelled bags, resulting in a more compact design. The compression mechanism includes a counterweight 10 positioned between the two oxygen bags 1, with a "T"-shaped cross-section to clamp between the two rollers 4 and compress the oxygen bags 1. While it is "T" shaped, it could also be triangular, with the two sides forming arcs that rest on the upper sides of the roller 4, and the middle section facilitating insertion between the two rollers 4.

[0033] It also includes an anti-detachment mechanism disposed between the protective sleeve 9 and the counterweight 10 to prevent the counterweight 10 from falling off. The anti-detachment mechanism includes a guide plate 11 fixed between the left and right protective sleeves 9, and a vertical guide groove 12 is provided in the middle of the guide plate 11. The front and rear ends of the counterweight 10 are fixed with "T"-shaped sliders 13 that are adapted to the guide groove 12. The sliders 13 can slide and guide within the guide groove 12 to ensure the smooth movement of the counterweight 10.

[0034] Working principle: As oxygen is consumed, the roller 4 moves downward under gravity, compressing the oxygen bag 1. This pressure is maintained by utilizing gravity. A pull rope 7 is wound around the roller 4. As the roller 4 moves downward, it rotates, winding the oxygen bag 1 to catch the escaping gas, maintaining pressure and preventing residue buildup, while also reducing space requirements. The counterweight 10 accelerates oxygen expulsion, allowing for better winding onto the roller 4. When filling the oxygen bag 1 with oxygen, the connector 3 is activated, inflating the bag and pushing the roller 4 to rotate and unwind until it returns to its initial position.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
