Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a respiratory humidifier. Background Technology

[0002] In the Intensive Care Unit (ICU), patients' conditions are critical and complex, often accompanied by respiratory dysfunction and other problems. Traditional respiratory care methods are insufficient to meet the precise and efficient respiratory support needs of ICU patients. For example, ordinary humidification methods cannot precisely control the degree of humidification and temperature, which can easily lead to damage to the respiratory mucosa, thickened sputum that is difficult to expel, and an increased risk of lung infection. ICU patients, due to their severe condition and low immunity, have extremely high requirements for respiratory care. As a key piece of equipment, the performance of respiratory humidifiers directly affects the patient's treatment outcome.

[0003] However, existing respiratory humidifiers have the following drawbacks:

[0004] (1) Existing respiratory humidifiers have simple structures, making it difficult to ensure the stability of the connection between the humidifier canister and the humidifier body, thus ensuring the normal operation of the humidifier;

[0005] (2) Existing respiratory humidifiers are usually one-piece units, which makes it difficult to quickly remove the filter cotton, thus reducing work efficiency.

[0006] Therefore, this utility model provides a respiratory humidifier. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a respiratory humidifier, including a humidifier body 1, a plurality of support components 2 fixedly connected to the bottom of the humidifier body 1, a humidification tank 3 provided on the top of the humidifier body 1, and fixing blocks 4 fixedly connected to both sides of the top of the humidifier body 1. A cavity is formed inside the fixing block 4, and a motor 5 is fixedly connected to the inner wall of the cavity. A transmission rod is splinedly connected to the output end of the motor 5, and a gear 6 is fixedly connected to one end of the transmission rod. Two racks 7 mesh on the surface of the gear 6, a slider 8 is fixedly connected to one end of the racks 7, and a clamping block 9 is fixedly connected to one end of the slider 8. An arc-shaped groove adapted to the humidification tank 3 is formed on the opposite side of each clamping block 9. An input pipe 10 is installed on the top of the humidification tank 3. The oxygen tube 11, through the arrangement of motor 5, gear 6, rack 7, slider 8, and clamping blocks 9, fixes the humidification tank 3. First, motor 5 is started to drive gear 6 to rotate, which drives the meshing rack 7 to move linearly, causing slider 8 to slide linearly on the corresponding track. Slider 8 drives clamping blocks 9 to move towards humidification tank 3. Finally, the arc-shaped grooves of the two clamping blocks 9 tightly clamp humidification tank 3, thus fixing humidification tank 3 and ensuring the stability of the connection between humidification tank 3 and humidifier body 1, thereby ensuring the normal operation of humidifier. The top of the input pipe 10 is fixedly connected to the mounting block 12, and a mounting plate 13 is provided on one side of the mounting block 12. A mounting frame is fixedly connected to one side of the mounting plate 13, and a filter is fixedly connected to the inner surface of the mounting frame. The cotton 14 and the mounting block 12 have a rectangular groove on one side that matches the mounting frame. The mounting frame is movably connected to the inner wall of the rectangular groove. Fixing plates 15 are fixedly connected to both sides of the mounting plate 13. Rotating blocks 16 are rotatably connected to both sides of the mounting block 12. A circular groove is formed on one side of the rotating block 16. A telescopic rod 17 is movably connected to the inner wall of the circular groove. A spring 18 is connected between one side of the telescopic rod 17 and the inner wall of the circular groove. A locking hole matching the telescopic rod 17 is formed on one side of the fixing plate 15. A locking plate 19 is fixedly connected to one end of the telescopic rod 17. One side of the locking plate 19 contacts one side of the fixing plate 15. The mounting plate 13, filter cotton 14, fixing plate 15, rotating block 16, telescopic rod 17, spring 18, and locking plate are all connected together. When the filter cotton 14 needs to be removed, first pull the lever 22 so that it moves the telescopic rod 17 through the clamping plate 19. At the same time, stretch the spring 18 so that the clamping plate 19 disengages from the clamping hole of the fixing plate 15. Then, rotate the rotating block 16 so that it drives the telescopic rod 17 and the clamping plate 19 to rotate together and move away from the clamping plate 19. This releases the locking and fixing state between the fixing plate 15 and the rotating block 16. The mounting plate 13 is no longer restricted by the fixing block 16. At this time, the mounting plate 13 can be pulled out from the rectangular groove on the mounting block 12 so that the filter cotton 14 can also be removed. The whole process does not require the use of additional tools, is simple and convenient to operate, and can quickly complete the removal of the filter cotton 14, improving work efficiency.

[0029] A limiting rod 20 is fixedly connected to the inner wall of the cavity. The limiting rod 20 ensures the stability of the slider 8 when it moves. A circular hole that matches the limiting rod 20 is opened on one side of the slider 8. The limiting rod 20 is movably connected to the inner wall of the circular hole.

[0030] A limiting block 21 is fixedly connected to the surface of the telescopic rod 17. By setting the limiting block 21, the limiting block 21 can ensure that the telescopic rod 17 moves in a specific position. The inner side wall of the circular groove is provided with a limiting groove that matches the limiting block 21. The limiting block 21 is movably connected to the inner side wall of the limiting groove.

[0031] A pull rod 22 is fixedly connected to the other side of the card plate 19. The pull rod 22 makes it easy for medical staff to pull the card plate 19. The pull rods 22 are arranged symmetrically.

[0032] A positioning rod 23 is fixedly connected to one side of the mounting plate 13. With the setting of the positioning rod 23, the positioning rod 23 can accurately determine the relative position between the mounting plate 13 and the mounting block 12. A positioning groove adapted to the positioning rod 23 is opened on one side of the mounting block 12.

[0033] A protective pad 24 is fixedly connected to the inner surface of the arc-shaped groove. The protective pad 24 can reduce the damage of the clamping block 9 to the humidification tank 3. The protective pad 24 is arc-shaped.

[0034] In this invention, the working steps of the device are as follows:

[0035] First step: First, start the motor 5 to drive the gear 6 to rotate, which drives the meshing rack 7 to move in a straight line, so that the slider 8 slides in a straight line on the corresponding track, and the slider 8 drives the clamping block 9 to move towards the humidification tank 3. Finally, the arc-shaped grooves of the two clamping blocks 9 tightly clamp the humidification tank 3, thereby fixing the humidification tank 3 and ensuring the stability of the connection between the humidification tank 3 and the humidifier body 1, thus ensuring the normal operation of the humidifier.

[0036] The second step: Next, pull the lever 22, which moves the telescopic rod 17 through the clamping plate 19, and at the same time stretches the spring 18, causing the clamping plate 19 to disengage from the clamping hole of the fixed plate 15. Then, rotate the rotating block 16, which causes the telescopic rod 17 and the clamping plate 19 to rotate together and move away from the clamping plate 19, thereby releasing the locking and fixing state between the fixed plate 15 and the rotating block 16. The mounting plate 13 is no longer restricted by the rotating block 16. At this time, the mounting plate 13 can be pulled out from the rectangular groove on the mounting block 12, and the filter cotton 14 can also be taken out. The whole process does not require the use of additional tools, is simple and convenient to operate, and can quickly complete the removal of the filter cotton 14, improving work efficiency.
