Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a humidifier structure for an oxygen inhalation tube. Background Art

[0002] In the nursing of the respiratory department, patients with dyspnea need to use an oxygen inhalation machine for assisted breathing. When using the oxygen inhalation machine for assisted breathing, a humidifier is an important instrument for the oxygen inhalation machine. When a patient inhales oxygen, the humidifier can allow medical staff to intuitively observe the dynamics of the patient during oxygen inhalation. At the same time, it can increase the humidity of the oxygen inhaled by the patient, achieve the purpose of moistening the alveoli and increasing the activity of the alveoli, and thus is beneficial to gas exchange.

[0003] The oxygen inhalation tube for supplying oxygen to the patient is connected to the output joint of the humidifier. Usually, there is a lack of additional protection at the connection between the oxygen inhalation tube and the output joint of the humidifier. When the patient makes excessive movements or is subjected to excessive external forces, the oxygen inhalation tube is likely to fall off from the output joint of the humidifier, affecting the normal oxygen inhalation of the patient. In addition, since the oxygen inhalation tube is relatively soft, the connection between it and the output joint of the humidifier is prone to excessive bending, resulting in blockage and affecting the normal supply of oxygen. Content of the Utility Model

[0004] The purpose of the utility model is to provide a humidifier structure for an oxygen inhalation tube, which can prevent the oxygen inhalation tube from falling off due to excessive force, and at the same time can also prevent excessive bending at the position where the oxygen inhalation tube is connected to the output joint of the humidifier, thus effectively solving the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions.

[0006] A humidifier structure for an oxygen inhalation tube includes a humidifying tank and an oxygen inhalation tube. The oxygen inhalation tube is connected to an output joint on one side of the humidifying tank. An fixing plate is fixed outside the output joint. A horizontally extending support mounting plate is fixed at the bottom end of the fixing plate. The fixing plate and the support mounting plate form an L-shaped structure. An upwardly arched arc-shaped elastic support piece is arranged above the support mounting plate. One end of the arc-shaped elastic support piece is hinged to the upper surface of the support mounting plate, and the other end is in movable contact with the upper surface of the support mounting plate. Two rows of limiting stop rods extending along the extending direction of the arc-shaped elastic support piece are arranged on the arc-shaped elastic support piece. A limiting space is formed between the two rows of limiting stop rods. The oxygen inhalation tube is supported above the arc-shaped elastic support piece and is limited within the limiting space.

[0007] Thus, when the oxygen inhalation tube is overloaded, the arc-shaped elastic support piece will be squeezed. Since the arc-shaped elastic support piece has the ability of elastic deformation, it will deform into a straight line state when compressed, effectively buffering the force on the oxygen inhalation tube and preventing the oxygen inhalation tube from being overly pulled and falling off. Since the arc-shaped elastic support piece supports under the oxygen inhalation tube, the extension trajectory of the oxygen inhalation tube also tends to be an upward-arching arc shape, thus smoothly changing the direction of the oxygen inhalation tube and preventing the connection between the oxygen inhalation tube and the output joint from being overly bent and blocked, which affects oxygen supply.

[0008] Furthermore, the support mounting plate is provided with a through slot extending along the length direction of the support mounting plate. The oxygen inhalation tube passes through the through slot, and the outer wall of the oxygen inhalation tube is in sliding fit with the inner wall of the through slot.

[0009] By providing space for the oxygen inhalation tube through the through slot, it can ensure that the oxygen inhalation tube can smoothly extend upward and prevent the oxygen inhalation tube from being overly bent due to contact with the end of the support mounting plate.

[0010] Furthermore, a second U-shaped seat is fixed on the upper surface of the support mounting plate between the through slot and the output joint. A second shaft rod is rotatably installed in the second U-shaped seat, and one end of the arc-shaped elastic support piece close to the output joint is fixedly sleeved on the second shaft rod.

[0011] The hinge connection between the arc-shaped elastic support piece and the support mounting plate is realized by using the second U-shaped seat and the second shaft rod, which facilitates the rotation of the arc-shaped elastic support piece when the oxygen inhalation tube is overly pulled and flattens the arc-shaped elastic support piece.

[0012] Furthermore, a first U-shaped seat is fixed on the inner edge surface of the arc-shaped elastic support piece on the side away from the output joint. A first shaft rod is rotatably installed in the first U-shaped seat, and a guide roller is fixedly sleeved on the first shaft rod. The guide roller is in contact with the upper surface of the support mounting plate.

[0013] When the oxygen inhalation tube is overly pulled and flattens the arc-shaped elastic support piece, the guide roller can roll along the upper surface of the support mounting plate, ensuring that the deformation process of the arc-shaped elastic support piece is smooth and fluent. In addition, when the arc-shaped elastic support piece is flattened, the guide roller moves to the inner end wall close to the side of the through slot away from the output joint, and the guide roller cooperates with the inner end wall of the through slot on the side away from the output joint to clamp the oxygen inhalation tube, achieving a limiting effect and preventing the oxygen inhalation tube from falling off the output joint due to excessive force.

[0014] Furthermore, the width of the guide roller is greater than the width of the through slot to ensure that the guide roller can cross the through slot and contact the upper surface of the support mounting plate.

[0015] Furthermore, the side of the humidifying tank also has an input joint, and a diversion tube is connected to the input joint. The diversion tube is connected to the oxygen tank.

[0016] Oxygen in the oxygen tank can be supplied to the input connector and the humidifying tank through the diversion tube, and finally transported to the patient's nasal cavity through the output connector and the oxygen inhalation tube to achieve the supply of oxygen.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows.

[0018] 1. When the oxygen inhalation tube is excessively stressed in the present utility model, it will squeeze the arc-shaped elastic support piece. Since the arc-shaped elastic support piece has the ability of elastic deformation, it will deform to a straight state when compressed, effectively buffering the force on the oxygen inhalation tube and preventing the oxygen inhalation tube from being excessively pulled and falling off.

[0019] 2. Since the arc-shaped elastic support piece in the present utility model supports below the oxygen inhalation tube, the extension trajectory of the oxygen inhalation tube also tends to be an upward-arching arc shape, thereby smoothly reversing the oxygen inhalation tube and preventing the connection between the oxygen inhalation tube and the output connector from being excessively bent and blocked, which affects oxygen supply.

[0020] 3. When the oxygen inhalation tube is excessively pulled and flattens the arc-shaped elastic support piece in the present utility model, the guide roller can roll along the upper surface of the support mounting plate, ensuring that the deformation process of the arc-shaped elastic support piece is smooth and fluent. In addition, when the arc-shaped elastic support piece is flattened, the guide roller moves to the inner end wall near the threading notch and away from the output connector side. The guide roller cooperates with the inner end wall of the threading notch away from the output connector side to clamp the oxygen inhalation tube, achieving a limiting effect and preventing the oxygen inhalation tube from falling off the output connector due to excessive force.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 4 , a humidifier structure of an oxygen inhalation tube provided by the present utility model includes a humidifying tank 1 and an oxygen inhalation tube 01. The oxygen inhalation tube 01 is connected to an output joint 11 on one side of the humidifying tank 1. A fixing plate 2 is fixed outside the output joint 11. A horizontally extending support mounting plate 3 is fixed at the bottom end of the fixing plate 2. The fixing plate 2 and the support mounting plate 3 form an L-shaped structure. An upwardly arched arc-shaped elastic support piece 4 is arranged above the support mounting plate 3. One end of the arc-shaped elastic support piece 4 is hinged to the upper surface of the support mounting plate 3, and the other end is movably abutted against the upper surface of the support mounting plate 3. Two rows of limiting stop rods 41 extending along the extending direction of the arc-shaped elastic support piece 4 are arranged on the arc-shaped elastic support piece 4. A limiting space 42 is formed between the two rows of limiting stop rods 41. The oxygen inhalation tube 01 is supported above the arc-shaped elastic support piece 4 and is limited within the limiting space 42.

[0028] During the respiratory care, when the patient uses this humidifier structure for oxygen inhalation, the oxygen inhalation tube 01 is connected to the output joint 11, and the oxygen inhalation tube 01 is placed within the limiting space 42 formed by the two rows of limiting stop rods 41 at the top of the arc-shaped elastic support piece 4. Since one end of the arc-shaped elastic support piece 4 is hinged to the support mounting plate 3 and the other end is movable, when the patient moves excessively and causes the oxygen inhalation tube 01 to be overstressed, it will squeeze the arc-shaped elastic support piece 4. Since the arc-shaped elastic support piece 4 has the ability of elastic deformation, it will deform to a straight state when compressed, effectively buffering the force on the oxygen inhalation tube 01 and preventing the oxygen inhalation tube 01 from being overly pulled and falling off. At the same time, the arc-shaped elastic support piece 4 has elasticity and can automatically reset. In addition, since the arc-shaped elastic support piece 4 supports the oxygen inhalation tube 01 from below, the extending trajectory of the oxygen inhalation tube 01 also tends to be an upwardly arched arc shape, thereby smoothly changing the direction of the oxygen inhalation tube 01 and preventing the connection between the oxygen inhalation tube 01 and the output joint 11 from being overly bent and blocked, affecting oxygen supply. The oxygen inhalation tube 01 is limited within the limiting space 42 between the two rows of limiting stop rods 41, and the limiting stop rods 41 can block the oxygen inhalation tube 01, preventing the oxygen inhalation tube 01 from slipping off from the side of the arc-shaped elastic support piece 4 and ensuring stability.

[0029] Specifically, the support mounting plate 3 is provided with a through slot 31 extending vertically, and the through slot 31 extends along the length direction of the support mounting plate 3. The oxygen inhalation tube 01 passes through the through slot 31, and the outer wall of the oxygen inhalation tube 01 is in sliding fit with the inner wall of the through slot 31. By providing space for the oxygen inhalation tube 01 through the through slot 31, it can ensure that the oxygen inhalation tube 01 can smoothly extend upward, avoiding excessive bending of the oxygen inhalation tube 01 due to contact with the end of the support mounting plate 3.

[0030] Specifically, a second U-shaped seat 46 is fixed on the upper surface of the support mounting plate 3 between the through slot 31 and the output joint 11. A second shaft rod 47 is rotatably installed in the second U-shaped seat 46. One end of the arc-shaped elastic support piece 4 close to the output joint 11 is fixedly sleeved on the second shaft rod 47. The second U-shaped seat 46 and the second shaft rod 47 are used to realize the hinged connection between the arc-shaped elastic support piece 4 and the support mounting plate 3, facilitating the rotation of the arc-shaped elastic support piece 4 when the oxygen inhalation tube 01 is overly pulled and flattens the arc-shaped elastic support piece 4.

[0031] Specifically, a first U-shaped seat 43 is fixed on the inner surface of the arc-shaped elastic support piece 4 on the side far from the output joint 11. A first shaft rod 44 is rotatably installed in the first U-shaped seat 43. A guide roller 45 is fixedly sleeved on the first shaft rod 44, and the guide roller 45 is in contact with the upper surface of the support mounting plate 3. When the oxygen inhalation tube 01 is overly pulled and flattens the arc-shaped elastic support piece 4, the guide roller 45 can roll along the upper surface of the support mounting plate 3, ensuring that the deformation process of the arc-shaped elastic support piece 4 is smooth and fluent. In addition, when the arc-shaped elastic support piece 4 is flattened, the guide roller 45 moves to the inner end wall on the side of the through slot 31 far from the output joint 11. The guide roller 45 cooperates with the inner end wall on the side of the through slot 31 far from the output joint 11 to clamp the oxygen inhalation tube 01, achieving a limiting effect and preventing the oxygen inhalation tube 01 from falling off the output joint 11 due to excessive force.

[0032] Specifically, the width of the guide roller 45 is greater than the width of the through slot 31, ensuring that the guide roller 45 can straddle the through slot 31 and contact the upper surface of the support mounting plate 3.

[0033] Specifically, the side of the humidifying tank 1 also has an input joint 12. A diversion tube 02 is connected to the input joint 12, and the diversion tube 02 is connected to the oxygen tank. Through the diversion tube 02, the oxygen in the oxygen tank can be supplied to the input joint 12 and the humidifying tank 1, and finally delivered to the patient's nasal cavity through the output joint 11 and the oxygen inhalation tube 01 to realize the supply of oxygen.

[0034] The above is a detailed description of the present utility model in conjunction with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious variations are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present utility model.
