Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and more specifically to an oxygen humidification device for oxygen therapy and nursing. Background Technology

[0002] In clinical practice, respiratory medicine, as a department of modern Western medicine, often requires patients to receive oxygen. Oxygen administration increases arterial blood oxygen partial pressure and saturation, thereby increasing arterial blood oxygen content, correcting hypoxia, and promoting metabolism. Oxygen inhalation is a commonly used method, which involves administering oxygen at a concentration higher than that in the air to increase the oxygen partial pressure in the alveoli, thus improving tissue hypoxia. Currently, there are many types of oxygen inhalation devices; however, most of them involve inserting the oxygen tube into a humidifying solution to directly humidify the oxygen. Simultaneously, medications specific to the patient are added to the humidifying solution, allowing the medication to enter the patient's body with each breath, thus enhancing the therapeutic effect.

[0003] Existing technology mainly involves passing oxygen through a tube that extends deep into the bottom of the bottle. At the end, there is usually a bubble diffuser (such as an air stone). The oxygen is dispersed into countless tiny bubbles and directly introduced into sterile water. As the bubbles rise, they come into full contact with the water, humidifying the oxygen. The oxygen is then output from the outlet pipe. However, as the oxygen flows, the higher the oxygen flow rate, the shorter the contact time between the bubbles and the sterile water, resulting in poor humidification.

[0004] In view of the above, the present invention designs an oxygen humidification device for oxygen therapy nursing, which solves the above-mentioned technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an oxygen humidification device for oxygen therapy nursing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oxygen humidification device for oxygen therapy nursing, comprising a humidification bottle, the humidification bottle being cylindrical, with an air inlet pipe coaxially arranged in the middle of the humidification bottle, and an air outlet pipe arranged on one side of the air inlet pipe, both the air inlet pipe and the air outlet pipe extending into a humidification chamber opened inside the humidification bottle; the device further comprising: a sterile water storage tank, symmetrically arranged on both sides of the humidification bottle, and the sterile water storage tank being connected to the humidification chamber opened inside the humidification bottle via a sterile water delivery pipe; and a connecting cylinder, disposed inside the humidification chamber, and the connecting cylinder being coaxial with the humidification bottle. The humidification chamber is divided into two sealed spaces by the connecting cylinder, which are connected by a water outlet. A water replenishment mechanism is located between the connecting cylinder and the inner wall of the humidification chamber. This mechanism automatically supplies sterile water from the sterile water storage tank into the humidification chamber through a sterile water delivery pipe. A turbulence-disrupting mechanism is located inside the sealed cylinder and at the bottom of the humidification chamber. This mechanism separates large air bubbles generated by the inlet pipe and the sterile water into multiple smaller bubbles, increasing the contact time between oxygen and sterile water, thereby improving the humidification effect.

[0007] Preferably, a one-way valve is provided inside the sterile water delivery pipe. The one-way valve ensures that the sterile water in the sterile water storage tank can only flow into the humidification chamber along the sterile water delivery pipe, thus preventing backflow of sterile water.

[0008] Preferably, both the air inlet pipe and the air outlet pipe are located inside the humidification chamber, with the air inlet pipe extending to the bottom of the humidification chamber and the air outlet pipe located above the air inlet pipe, and the air inlet pipe located inside the connecting cylinder.

[0009] Preferably, a spiral blade is provided between the air inlet pipe and the connecting cylinder, and the spiral blade and the inner wall of the connecting cylinder form a spiral channel, thereby increasing the contact time between oxygen and sterile water.

[0010] Preferably, the water replenishment mechanism includes a moving ring, connecting rods, a fixed ring, and a suspended ball. The moving ring is slidably disposed within the sealed space formed by the connecting cylinder and the inner wall of the humidification chamber, and the outer circumferential surface of the moving ring is in contact with the inner wall of the humidification chamber. Multiple sets of connecting rods are disposed below the moving ring, and a suspended ball is disposed at the end of each connecting rod. A fixed ring is disposed below the moving ring, and the inner circumferential surface of the fixed ring is fixedly connected to the outer wall of the connecting cylinder. The outer circumferential surface of the fixed ring is fixedly connected to the inner wall of the humidification chamber. The connecting rods pass through the fixed ring, and the suspended ball is disposed in a conical groove opened on the fixed ring. When the water level of the sterile water drops, the suspended ball drives the moving ring to move downwards in the humidification chamber. At this time, the sterile water in the sterile water storage tank enters the humidification chamber through the sterile water delivery pipe.

[0011] Preferably, the turbulence-inducing mechanism includes a rotating shaft, a mounting block, turbine blades, a fixed base, and a rotating sleeve. The fixed base is located at the center of the bottom of the humidification chamber, and the rotating sleeve is rotatably mounted on the fixed base. The rotating shaft is coaxially mounted at the center of the rotating sleeve. The mounting block is located above the rotating shaft and is fixedly connected to the rotating shaft. Multiple sets of turbine blades are mounted on the mounting block, and multiple sets of turbulence-inducing blades are rotatably mounted on the rotating sleeve. When oxygen enters the humidification chamber through the air inlet pipe, the oxygen drives the turbine blades to rotate. The turbine blades drive the turbulence-inducing blades on the rotating sleeve to rotate synchronously through the rotating shaft, thereby separating the large air bubbles generated by the water inlet pipe and the sterile water into multiple small air bubbles, thus increasing the contact time between the oxygen and the sterile water.

[0012] Preferably, a cleaning hole is provided at the bottom of the humidification chamber, the cleaning hole is sealed by a waste sealing block, and the waste sealing block can slide up and down inside the cleaning hole.

[0013] The beneficial effects of this invention are:

[0014] 1. This invention provides an oxygen humidification device for oxygen therapy nursing. The device inputs oxygen into the humidification chamber through an inlet pipe. The flow of oxygen in the inlet pipe drives a turbulence-inducing mechanism to move synchronously. When oxygen comes into contact with sterile water and bubbles are generated, the turbulence-inducing mechanism agitates the sterile water, causing large bubbles to break down into smaller bubbles. Simultaneously, the turbulence-inducing mechanism alters the bubble trajectory, increasing the contact time between the bubbles and the sterile water, thereby enhancing the humidification effect. The combination of the turbulence-inducing mechanism and the spiral channel increases the bubble flow path, thus increasing the contact time between the bubbles and the sterile water, and further... Bubbles flow along a designated moving channel, ensuring oxygen is evenly discharged through the outlet pipe. After prolonged oxygen humidification, the sterile water in the humidification chamber is gradually consumed, requiring manual replenishment. However, replenishment during humidification can interfere with the sterile water supply. Therefore, a water replenishment mechanism works in conjunction with a sterile water storage tank. When the sterile water level in the humidification chamber drops, a pressure difference occurs between the humidification chamber and the sterile water storage tank, causing sterile water from the storage tank to enter the humidification chamber through a sterile water delivery pipe. This design enables automatic replenishment of sterile water, avoiding the problem of interference with the sterile water supply caused by manual replenishment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments. Based on the described 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.

[0024] refer to Figures 1 to 6As shown, an oxygen humidification device for oxygen therapy includes a humidification bottle 1, which is cylindrical in shape. An air inlet pipe 11 is coaxially arranged in the middle of the humidification bottle 1, and an air outlet pipe 12 is arranged on one side of the air inlet pipe 11. Both the air inlet pipe 11 and the air outlet pipe 12 extend into a humidification chamber 13 opened inside the humidification bottle 1. The device also includes: a sterile water storage tank 21, symmetrically arranged on both sides of the humidification bottle 1, and connected to the humidification chamber 13 inside the humidification bottle 1 via a sterile water delivery pipe 2; and a connecting cylinder 3, disposed inside the humidification chamber 13, and coaxially arranged with the humidification bottle 1. The connecting cylinder 3 divides the humidification chamber 13 into two sealed spaces, which are connected by a water outlet trough 31. The water replenishment mechanism 4 is located between the connecting cylinder 3 and the inner wall of the humidification chamber 13. The water replenishment mechanism 4 is used to automatically input sterile water from the sterile water storage tank 21 into the humidification chamber 13 through the sterile water delivery pipe 2. The turbulence 5 is located inside the sealed cylinder and at the bottom of the humidification chamber 13. The turbulence 5 is used to separate the large air bubbles generated by the water inlet pipe and the sterile water into multiple small air bubbles, thereby increasing the contact time between oxygen and sterile water and improving the humidification effect of oxygen.

[0025] Specifically, a one-way valve 22 is installed inside the sterile water delivery pipe 2. The one-way valve 22 ensures that the sterile water in the sterile water storage tank 21 can only flow along the sterile water delivery pipe 2 into the humidification chamber 13, thus preventing backflow of sterile water.

[0026] Specifically, the air inlet pipe 11 and the air outlet pipe 12 are both located inside the humidification chamber 13, with the air inlet pipe 11 extending to the bottom of the humidification chamber 13, and the air outlet pipe 12 located above the air inlet pipe 11, while the air inlet pipe 11 is located inside the connecting cylinder 3.

[0027] Specifically, a spiral blade is provided between the air inlet pipe 11 and the connecting cylinder 3, and the spiral blade and the inner wall of the connecting cylinder 3 form a spiral channel 32, which increases the contact time between oxygen and sterile water.

[0028] Specifically, the water replenishment mechanism 4 includes a movable ring 41, connecting rods 42, a fixed ring 43, and suspended balls 44. The movable ring 41 is slidably disposed within the sealed space formed by the connecting cylinder 3 and the inner wall of the humidification chamber 13, and the outer circumferential surface of the movable ring 41 is in contact with the inner wall of the humidification chamber 13. Multiple sets of connecting rods 42 are disposed below the movable ring 41, and each connecting rod 42 has a suspended ball 44 at its end. A fixed ring 43 is disposed below the movable ring 41, and the inner surface of the fixed ring 43... The outer circumferential surface of the fixed ring 43 is fixedly connected to the outer wall of the connecting cylinder 3, and the outer circumferential surface of the fixed ring 43 is fixedly connected to the inner wall of the humidification chamber 13. The connecting rod 42 is set through the fixed ring 43, and the suspended ball 44 is set in the conical groove 431 opened on the fixed ring 43. When the water level of the sterile water drops, the suspended ball 44 drives the moving ring 41 to move downwards in the humidification chamber 13. At this time, the sterile water in the sterile water storage tank 21 enters the humidification chamber 13 through the sterile water delivery pipe 2.

[0029] Specifically, the turbulence-inducing mechanism 5 includes a rotating shaft 51, a mounting block 52, turbine blades 53, a fixed base 54, and a rotating sleeve 55. The fixed base 54 is located at the center of the bottom of the humidification chamber 13. The rotating sleeve 55 is rotatably mounted on the fixed base 54. The rotating shaft 51 is coaxially mounted at the center of the rotating sleeve 55. The mounting block 52 is located above the rotating shaft 51. The mounting block 52 is fixedly connected to the rotating shaft 51. Multiple sets of turbine blades 53 are mounted on the mounting block 52. Multiple sets of turbulence-inducing blades 551 are rotatably mounted on the rotating sleeve 55. When oxygen enters the humidification chamber 13 through the air inlet pipe 11, the oxygen drives the turbine blades 53 to rotate. The turbine blades 53 drive the turbulence-inducing blades 551 mounted on the rotating sleeve 55 to rotate synchronously through the rotating shaft 51, thereby separating the large bubbles generated by the water inlet pipe and the sterile water into multiple small bubbles, thus increasing the contact time between the oxygen and the sterile water.

[0030] Specifically, a cleaning hole 6 is provided at the bottom of the humidification chamber 13. The cleaning hole 6 is sealed by a waste sealing block 61, and the waste sealing block 61 can slide up and down inside the cleaning hole 6.

[0031] During operation, the operator first connects the inlet pipe 11 to the oxygen delivery pipe and the outlet pipe 12 to the oxygen mask, thus bringing the oxygen mask into contact with the patient. At this time, the sterile water storage tank 21 is connected to the humidifier bottle 1 through the sterile water delivery pipe 2. After the connection is completed, the oxygen delivery device is started. Oxygen enters the bottom of the humidification chamber 13 through the inlet pipe 11. Oxygen and sterile water come into contact and generate bubbles. As the oxygen enters through the inlet pipe 11, the oxygen drives the turbine blades 53 installed on the mounting block 52 inside the inlet pipe 11 to move synchronously. The turbine blades 53 drive the rotating sleeve 55 to rotate on the fixed seat 54 through the rotating shaft 51. At this time, the rotating sleeve 55 drives the turbulence blades 551 installed on it to rotate synchronously. The turbulence blades 551 cut the large bubbles generated by the oxygen and sterile water into multiple small bubbles, thereby increasing the contact time between oxygen and sterile water. The bubbles move upward. At this time, the divided bubbles move upward through the spiral channel 32 and are delivered to the patient's oxygen mask through the outlet pipe 12.

[0032] After prolonged oxygen humidification, the sterile water in the humidification chamber 13 will be gradually consumed, requiring manual replenishment. However, replenishment during humidification can interfere with the sterile water supply. When the sterile water level in the humidification chamber 13 moves downward, the suspended ball 44 descends along with it, causing the connecting rod 42 to move synchronously. The suspended ball 44, through the connecting rod 42, drives the moving ring 41 downward. At this point, a pressure difference will appear between the humidification chamber 13 and the sterile water storage tank 21, causing the sterile water in the storage tank 21 to enter the humidification chamber 13 through the sterile water delivery pipe 2. To ensure the flow of sterile water and prevent backflow, a one-way valve 22 is installed in the sterile water delivery pipe 2. This design enables automatic replenishment of sterile water, thus avoiding the problem of interference with the sterile water supply caused by manual replenishment.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
