Description

Technical Field

[0001] This utility model belongs to the field of atomizer technology, specifically a magnetic oxygen concentrator atomizer quick connection device. Background Technology

[0002] The magnetic oxygen generator is an innovative oxygen-generating device that combines molecular sieve pressure swing adsorption technology with a magnetic control system. Its core advantage lies in adjusting the adsorption efficiency of the molecular sieve through a magnetic field, thereby achieving more precise oxygen concentration control and dynamic oxygen supply capability.

[0003] Magnetic oxygen concentrators are commonly used in the medical field for nebulization therapy to treat lung infections and respiratory diseases. Medication is injected into a nebulizer cup, which is then connected to the oxygen concentrator via a tubing. This allows the medication to be nebulized and inhaled into the patient's lungs. However, long-term observation has revealed that existing tubing and nebulizer cups are typically directly connected via an interference fit. The lack of a fixed structure between the tubing and the nebulizer cup makes them prone to separation when subjected to external force or pulling.

[0004] Therefore, this utility model provides a quick connection device for a magnetic oxygen concentrator nebulizer. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a quick connection device for a magnetic oxygen concentrator nebulizer is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A magnetic suction oxygen concentrator nebulizer quick connection device of this utility model includes a nebulizing cup; a connector is fixedly connected to the bottom of the nebulizing cup; a retaining ring is fixedly connected to the middle of the connector; a conduit is connected to the side wall of the connector; a fixing block is fixedly connected to the side wall of the conduit; a pair of retaining plates are hinged to the side wall of the fixing block by a torsion spring; retaining teeth are fixedly connected to the side wall of the retaining plates; and a pressing block is fixedly connected to the end of the retaining plates. Through the above structure, the retaining ring, the fixing block, and the retaining plates, together with the retaining teeth and the pressing block, can facilitate the connection between the conduit and the connector by locking the retaining teeth on the top of the retaining ring after the conduit and the connector are connected. This reduces the situation where the conduit and the connector are easily separated when pulled by external force due to the lack of a fixing structure, and improves the stability of the connection between the conduit and the connector.

[0007] Preferably, a pair of fixing frames are fixedly connected to the side wall of the nebulizer cup; a pair of sliding rods are slidably connected to the middle of the fixing frames; a first fixing plate is fixedly connected to the end of the sliding rod; a first spring is fixedly connected to the side wall of the first fixing plate; the end of the first spring is fixedly connected to the side wall of the fixing frame; a second fixing plate is fixedly connected to the end of the sliding rod away from the first spring; with the above structure, the fixing frames, sliding rods and the first fixing plate are set, and the first spring and the second fixing plate are used in conjunction, the patient can hold the second fixing plates on both sides, and then intermittently clench and open his / her hands, so as to allow the hands to have a certain amount of room to move during nebulization, thereby reducing the situation of holding the nebulizer cup in one position for a long time, which can easily cause hand fatigue.

[0008] Preferably, a plurality of retaining rings are installed at the bottom of the fixing block; a plurality of second springs are fixedly connected to the middle of the retaining rings; the retaining rings and the second springs are located outside the conduit; with the above structure, the retaining rings and the second springs can block the conduit from the connection position between the conduit and the fixing block when the conduit is bent, thereby limiting the degree of bending of the conduit and reducing the situation where the conduit is bent too much and affects the gas delivery in the conduit.

[0009] Preferably, a guide seat is fixedly connected to the end of the connector; the guide seat has an inverted frustum structure; with the above structure, the guide seat connecting the connector can expand the inside of the conduit so that the conduit can be sleeved on the outside of the connector, thereby reducing the situation where the inner diameter of the conduit is smaller than the outer diameter of the connector, making it difficult to sleeve the conduit on the connector.

[0010] Preferably, a fixing ring is fixedly connected to the middle of the connector; the fixing ring is close to the top of the guide seat; a sealing ring is installed on the side wall of the connector; the sealing ring is located between the fixing ring and the guide seat; when the conduit is sleeved on the outside of the connector, the sealing ring is close to the end of the connector and contacts the inner wall of the conduit, which can seal the conduit and the connector. With the above structure, the fixing ring and the sealing ring can facilitate the sealing between the conduit and the connector, so as to reduce the possibility of air leakage caused by gaps between the connector and the conduit.

[0011] Preferably, a baffle is fixed to the inner wall of the conduit; the baffle has a through hole in the middle; with the above structure, the baffle can be positioned when the conduit is connected to the connector, so that the locking teeth and the locking ring can be engaged, thereby reducing the need to constantly adjust the conduit to align the locking teeth and the locking ring, which would otherwise be a cumbersome, time-consuming and laborious process.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The magnetic oxygen concentrator nebulizer quick connection device of this utility model, by setting a retaining ring, a fixing block and a retaining plate, and cooperating with retaining teeth and a pressing block, can facilitate the connection of the tube and the connector by the retaining teeth locking the top of the retaining ring after the tube and the connector are connected. This can reduce the situation where the tube and the connector are easily separated when pulled by external force due to the lack of a fixing structure, and can improve the stability of the connection between the tube and the connector.

[0014] 2. The magnetic suction oxygen concentrator nebulizer quick connection device of this utility model, by setting a fixed frame, a sliding rod and a first fixed plate, and cooperating with a first spring and a second fixed plate, allows the patient to hold their hands on the second fixed plates on both sides, and then intermittently clench and open their hands, so as to allow the hands to have a certain amount of room to move during nebulization, thereby reducing the situation of holding the nebulizer cup in one position for a long time, which can easily cause hand fatigue.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown in the embodiment of this utility model, a quick connection device for a magnetic oxygen concentrator nebulizer includes a nebulizer cup 1; a connector 11 is fixedly connected to the bottom of the nebulizer cup 1; a retaining ring 12 is fixedly connected to the middle of the connector 11; a conduit 13 is connected to the side wall of the connector 11; a fixing block 14 is fixedly connected to the side wall of the conduit 13; a pair of retaining plates 15 are hinged to the side wall of the fixing block 14 by a torsion spring; retaining teeth 16 are fixedly connected to the side wall of the retaining plates 15; and a pressing block 17 is fixedly connected to the end of the retaining plates 15. During operation, when connecting the conduit 13 to the connector 11, pressing the pressing blocks 17 on both sides with fingers causes the retaining plates 15 to open. Then, simultaneously pinching the fixing block 14 and the pressing block 17, inserting the conduit 13 into the connector 11 and fitting it over the outside of the connector 11, then aligning the retaining teeth 16 with the top of the retaining ring 12, and then releasing the pressing block 17, the retaining plates... Under the rebound of the torsion spring, plate 15 becomes converging and the locking teeth 16 are locked on the top of the retaining ring 12. At this time, the connection between the conduit 13 and the connector 11 can be completed. After use, the retaining plate 15 can be opened by pressing the button 17 again. At this time, the locking teeth 16 can be moved away from the top of the retaining ring 12. Then, by pinching the fixing block 14 and the button 17, the conduit 13 can be pulled to remove it from the connector 11. Through the above structure, the retaining ring 12, the fixing block 14 and the retaining plate 15 are set up. With the locking teeth 16 and the button 17, it is easy to lock the conduit 13 on the top of the retaining ring 12 after the conduit 13 is connected to the connector 11. This can reduce the situation where the conduit 13 and the connector 11 are easily separated when pulled by external force due to the lack of a fixing structure. This can improve the stability of the connection between the conduit 13 and the connector 11.

[0026] like Figure 1As shown, a pair of fixing frames 2 are fixedly connected to the side wall of the nebulizer cup 1; a pair of sliding rods 21 are slidably connected to the middle of the fixing frame 2; a first fixing plate 22 is fixedly connected to the end of the sliding rod 21; a first spring 23 is fixedly connected to the side wall of the first fixing plate 22; the end of the first spring 23 is fixedly connected to the side wall of the fixing frame 2; a second fixing plate 24 is fixedly connected to the end of the sliding rod 21 away from the first spring 23; during operation, when the patient is nebulizing, they need to hold the nebulizer cup 1 with their hand. Since the nebulization time is usually long, the patient's hand will become fatigued if they hold the nebulizer cup 1 for a long time. At this time, the patient can hold the second fixing plates 24 on both sides of the nebulizer cup 1 and then intermittently... By gripping and releasing the hand, when the hand is gripped, the first fixing plate 22 and the slide rod 21 move closer to the surface of the nebulizer cup 1. At this time, the first spring 23 will be in a stretched state. Then, when the hand is released, the first spring 23 will contract and rebound, causing the slide rod 21, the first fixing plate 22, and the second fixing plate 24 to return to their original positions. Through the above structure, with the fixing frame 2, the slide rod 21, and the first fixing plate 22, and in conjunction with the first spring 23 and the second fixing plate 24, the patient can hold the second fixing plates 24 on both sides and then intermittently grip and open their hands, so that the hands have a certain amount of room to move during nebulization, thereby reducing the situation of holding the nebulizer cup 1 in one position for a long time, which can easily lead to hand fatigue.

[0027] like Figure 4 As shown, multiple retaining rings 3 are installed at the bottom of the fixing block 14; multiple second springs 31 are fixedly connected to the middle of the retaining rings 3; the retaining rings 3 and the second springs 31 are located outside the conduit 13; during operation, since the material of the conduit 13 is relatively soft, it is easy to bend at the connection with the fixing block 14, which will hinder the normal delivery of gas. When the connection between the conduit 13 and the fixing block 14 bends, it will squeeze the outer retaining rings 3. When the upper and lower retaining rings 3 are in contact with each other, the conduit 13 will no longer bend. When the conduit 13 is no longer bent after use, the second springs 31 will rebound and drive the retaining rings 3 to reset. Through the above structure, the retaining rings 3 and the second springs 31 can block the conduit 13 from the connection position between the conduit 13 and the fixing block 14 when the conduit 13 bends, and limit the degree of bending of the conduit 13 to reduce the situation where the conduit 13 bends too much and affects the delivery of gas in the conduit 13.

[0028] like Figure 3 and Figure 5As shown, a guide seat 4 is fixedly connected to the end of the connector 11; the guide seat 4 has an inverted frustum structure; during operation, when the conduit 13 is fitted onto the outside of the connector 11, the end of the conduit 13 will first contact the guide seat 4. Usually, the inner diameter of the conduit 13 is smaller than the outer diameter of the connector 11. At this time, the guide seat 4 will open up the inside of the conduit 13. Then, as the conduit 13 continues to move, it will slide outside the guide seat 4 and then fit onto the outside of the connector 11. Through the above structure, the guide seat 4 is connected to the connector 11. By opening up the inside of the conduit 13, it is easier to fit the conduit 13 onto the outside of the connector 11, thereby reducing the situation where the inner diameter of the conduit 13 is smaller than the outer diameter of the connector 11, which would make it difficult to fit the conduit 13 onto the connector 11.

[0029] like Figure 5 As shown, a fixing ring 5 is fixedly connected to the middle of the connector 11; the fixing ring 5 is close to the top of the guide seat 4; a sealing ring 51 is installed on the side wall of the connector 11; the sealing ring 51 is located between the fixing ring 5 and the guide seat 4; during operation, after the conduit 13 is sleeved on the outside of the connector 11, the sealing ring 51 is close to the end of the connector 11 and contacts the inner wall of the conduit 13, which can seal the conduit 13 and the connector 11. Through the above structure, the fixing ring 5 and the sealing ring 51 can facilitate the sealing between the conduit 13 and the connector 11, so as to reduce the possibility of air leakage caused by gaps between the connector 11 and the conduit 13.

[0030] like Figure 4 As shown, a baffle 6 is fixed to the inner wall of the conduit 13; a through hole 61 is provided in the middle of the baffle 6; during operation, when the conduit 13 is fitted onto the outside of the connector 11, as the top of the conduit 13 moves toward the bottom of the atomizing cup 1, it will drive the baffle 6 toward the guide seat 4. When the baffle 6 contacts the guide seat 4, it proves that the conduit 13 has been fitted in place. At this time, the locking teeth 16 are aligned with the retaining ring 12. Then the locking teeth 16 are locked onto the top of the retaining ring 12, and then the gas flows normally through the through hole 61. Through the above structure, the baffle 6 can be set to facilitate positioning when the conduit 13 is connected to the connector 11, so that the locking teeth 16 can be locked onto the retaining ring 12, thereby reducing the need to constantly adjust the conduit 13 to align the locking teeth 16 with the retaining ring 12, which would otherwise be a cumbersome, time-consuming and laborious process.

[0031] like Figure 4 As shown, a silicone pad 7 is fixedly attached to the inner wall of multiple retaining rings 3. During operation, when the conduit 13 is bent, it will continuously rub against the inner wall of the retaining ring 3. At this time, the conduit 13 will come into contact with the silicone pad 7 inside the retaining ring 3. Through the above structure, the silicone pad 7 is connected to the retaining ring 3. Its flexible material can protect the conduit 13 to reduce the damage caused by long-term friction between the conduit 13 and the retaining ring 3.

[0032] Working principle: When connecting the conduit 13 to the connector 11, press the two side blocks 17 with your fingers to open the retaining plate 15. Then, simultaneously pinch the fixing block 14 and the block 17, insert the conduit 13 into the connector 11 and place it over the outside of the connector 11. Then, align the retaining teeth 16 with the top of the retaining ring 12. At this point, release the block 17. The retaining plate 15 will then close under the rebound of the torsion spring, and the retaining teeth 16 will lock onto the top of the retaining ring 12. This completes the connection between the conduit 13 and the connector 11. After use, press the block 17 again to open the retaining plate 15, which will move the retaining teeth 16 away from the top of the retaining ring 12. Then, pinch the fixing block 14 to close the retaining plate 15. Block 14 and button 17 pull the catheter 13 to remove it from the connector 11. When the patient is undergoing nebulization, they need to hold the nebulizer cup 1 with their hand. Since the nebulization time is usually long, the patient's hand will become fatigued if they hold the nebulizer cup 1 for a long time. At this time, the patient can hold the second fixing plate 24 on both sides of the nebulizer cup 1 and then intermittently tighten and loosen their hand. When the hand is tightened, the first fixing plate 22 and the slide rod 21 will move closer to the surface of the nebulizer cup 1. At this time, the first spring 23 will be in a stretched state. Then, when the hand is released, the first spring 23 will contract and rebound, driving the slide rod 21 and the first fixing plate 22 to move closer together. The second fixing plate 24 is reset. Because the material of the conduit 13 is relatively soft, it is prone to bending at the connection point with the fixing block 14 during use, which would hinder the normal delivery of gas. When the connection point of the conduit 13 and the fixing block 14 bends, it will compress the outer retaining ring 3. When the upper and lower retaining rings 3 contact each other end to end, the conduit 13 will no longer bend. After use, when the conduit 13 is no longer bending, the second spring 31 will rebound and drive the retaining ring 3 to reset. When the conduit 13 is fitted onto the outside of the connector 11, the end of the conduit 13 will first contact the guide seat 4. Typically, the inner diameter of the conduit 13 is smaller than the outer diameter of the connector 11. At this time, the guide seat... 4 will open the inside of the tube 13, and then as the tube 13 continues to move, it will slide outside the guide seat 4 and then be fitted onto the outside of the connector 11. When the tube 13 is fitted onto the outside of the connector 11, as the top of the tube 13 moves towards the bottom of the atomizing cup 1, it will drive the baffle 6 to move closer to the guide seat 4. When the baffle 6 contacts the guide seat 4, it proves that the tube 13 has been fitted in place. At this time, the locking tooth 16 is aligned with the locking ring 12. Then the locking tooth 16 is locked onto the top of the locking ring 12, and then the gas flows normally from the through hole 61. When the tube 13 bends, it will continuously rub against the inner wall of the baffle ring 3. At this time, the tube 13 will contact the silicone pad 7 inside the baffle ring 3.
