Description

Technical Field

[0001] This utility model relates to the field of medical nebulizer technology, and in particular to a nebulizer device for thoracic surgery nursing. Background Technology

[0002] Medical nebulizers are commonly used physiotherapy devices for respiratory diseases. They can break down liquid medications into tiny droplets, making it convenient for patients to inhale them directly into the airways and lungs. Unlike ordinary humidifiers, the size of the particles produced can be controlled, allowing the medication to bypass the digestive tract and act directly on the lesions in the trachea and bronchi, resulting in faster onset of action and reducing gastrointestinal discomfort caused by oral medications.

[0003] Currently, most patients undergoing thoracic surgery experience wound pain and insufficient respiratory tolerance. Nebulization therapy requires frequent disassembly and reassembly of the nebulizer cup tubing. Existing nebulizer devices often use simple plug-in connectors, achieving a sealed connection through interference fit between connectors. However, disassembling the tubing requires forceful pulling, causing stretching of the tubing connector material. After prolonged clinical use, gaps and air leaks can easily occur, leading to fluctuations in the concentration of the nebulized medication and affecting the efficacy of drug delivery to the lungs. Utility Model Content

[0004] The purpose of this invention is to provide a nebulizer for thoracic surgical care, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A nebulizer device for thoracic surgery care includes a nebulizer main unit. An air inlet is fixedly installed on the front side of the nebulizer main unit. A self-locking air outlet connector is provided on the nebulizer main unit located below the air inlet. The self-locking air outlet connector includes a fixed pad fixedly installed on the front side of the nebulizer main unit. A movable push plate is movably installed on the front side of the fixed pad. An air outlet tube is horizontally fixedly installed at the middle position of the movable push plate. A storage air bag is fixedly installed on the side of the movable push plate opposite to the storage air bag. A sleeve is detachably fixedly installed on the side of the movable push plate away from the storage air bag. A groove is integrally formed on the outer side of the sleeve. A sealing air bag is fixedly installed in the groove.

[0006] As a further preferred embodiment of this utility model, two fasteners are symmetrically fixedly installed on the front side of the fixed pad. When the movable push plate moves towards the fixed pad under force, the two fasteners can be used to reset and restrict the movable push plate by means of the protruding parts of the movable push plate relative to it. Multiple locking bolts are inserted and installed inside the fixed pad. A pressure ring is fixedly installed on the outside of the locking bolt. One end of the locking bolt is threaded to the front side of the atomizer host. The rear side of the pressure ring abuts against the front side of the fixed pad. Thus, the fixed pad is fixedly installed on the front side of the atomizer host by means of the cooperation of multiple sets of locking bolts and pressure rings, and at the same time, the multiple locking bolts provide conditions for the installation of the movable push plate on the front side of the fixed pad.

[0007] As a further preferred embodiment of this utility model, the front side of the movable push plate is integrally formed with an annular fixing ring along the outer wheel of the air outlet pipe. The movable push plate located between the air outlet pipe and the fixing ring has multiple first air holes, thereby enabling the air in the storage airbag to transfer between the internal cavities of the storage airbag and the sealing airbag through the multiple first air holes. The two sides of the movable push plate have buckle grooves that are adapted to the buckle pieces. When the movable push plate moves towards the fixing pad, the two buckle pieces on the front side of the fixing pad deform and lock into the front side of the movable push plate, thereby preventing the movable push plate from resetting and keeping the storage airbag in a continuously compressed state.

[0008] As a further preferred embodiment of this utility model, one end of the air outlet pipe is connected to the output end of the compressor pump inside the atomizer main unit via a flexible hose.

[0009] As a further preferred embodiment of this utility model, an annular sealing groove is provided on the front side of the vent pipe along its contour to provide a sealing basis for the connection between the sleeve and the vent pipe.

[0010] As a further preferred embodiment of this utility model, a connecting cap is integrally formed at one end of the sleeve relative to the movable push plate, a positioning ring is integrally formed at the other end of the sleeve away from the connecting cap, a sealing ring is integrally formed at one end of the positioning ring relative to the air outlet pipe, the connecting cap is threaded onto the fixing ring, and the sealing ring is inserted and installed in the sealing groove.

[0011] As a further preferred embodiment of this utility model, the bottom surface of the settling tank is provided with a plurality of second air holes. The inner cavity of the sealing airbag is connected to the inner cavity of the storage airbag through the second air holes and the sleeve and the first air holes. When the storage airbag is compressed, the air in the storage airbag will enter the cavity between the sleeve and the air outlet through the plurality of first air holes, and finally enter the sealing airbag through the plurality of second air holes to inflate the sealing airbag.

[0012] As a further preferred embodiment of this utility model, a compression spring is fitted on the outside of the storage airbag. One end of the compression spring abuts against the front side of the fixed pad, and the other end abuts against the rear side of the movable push plate. After the fastener releases the restriction on the movable push plate, the rebound force of the compression spring pushes the movable push plate to reset, so that the air in the sealed airbag is recovered into the storage airbag.

[0013] As a further preferred embodiment of this utility model, a medicine cup connecting tube is inserted and installed on the outside of the sleeve. After the sealing airbag expands, it can complete the connection and sealing between the sleeve and the medicine cup connecting tube. The static friction force on the connecting end of the medicine cup connecting tube can be relieved by the contraction of the sealing airbag, so that the connecting end of the medicine cup connecting tube can be quickly separated from the sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a self-locking air outlet connector is provided on the front side of the nebulizer main unit. By relying on the air pressure linkage structure between the storage airbag and the sealing airbag, the medicine cup connecting tube can be automatically sealed and locked. After the sealing airbag expands, it can completely seal the connection gap. At the same time, with the fastener limit and spring reset structure, disassembly and assembly do not require tools. This reduces the difficulty of clinical nursing operations, prevents the probability of medicine cup connecting tube breakage, and reduces the cost of equipment consumable replacement.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-6 As shown, the present invention provides a nebulizer for thoracic surgery nursing, including a nebulizer main unit 1. An air inlet 2 is fixedly installed on the front side of the nebulizer main unit 1. The nebulizer main unit 1 located below the air inlet 2 is provided with a self-locking air outlet connector 3. The self-locking air outlet connector 3 includes a fixed pad 4 fixedly installed on the front side of the nebulizer main unit 1. A movable push plate 5 is movably installed on the front side of the fixed pad 4. An air outlet pipe 6 is horizontally fixedly installed in the middle of the movable push plate 5. A storage air bag 7 is fixedly installed on the side of the movable push plate 5 opposite to the fixed pad 4. A sleeve 8 is detachably fixedly installed on the side of the movable push plate 5 away from the storage air bag 7. A groove 9 is integrally formed on the outer side of the sleeve 8. A sealing air bag 10 is fixedly installed in the groove 9.

[0019] Two fasteners 14 are symmetrically fixedly installed on the front side of the fixed pad 4. When the movable push plate 5 moves towards the fixed pad 4 under force, the two fasteners 14 can be used to reset and limit the movable push plate 5 by means of the protruding parts of the movable push plate 5 relative to it. Multiple locking bolts 12 are inserted inside the fixed pad 4. A pressure ring 13 is fixedly installed on the outside of the locking bolts 12. One end of the locking bolt 12 is threaded to the front side of the atomizer host 1, and the rear side of the pressure ring 13 abuts against the front side of the fixed pad 4. Thus, the fixed pad 4 is fixedly installed on the front side of the atomizer host 1 by means of the cooperation of multiple sets of locking bolts 12 and pressure ring 13, and at the same time, the multiple locking bolts 12 fix the movable push plate 5 to the fixed pad. The installation on the front side of plate 4 provides the conditions. The front side of the movable push plate 5 has an annular fixing ring 15 integrally formed along the outer wheel of the air outlet pipe 6. The movable push plate 5 located between the air outlet pipe 6 and the fixing ring 15 has multiple first air holes 17, so that the air in the storage airbag 7 can be transferred between the storage airbag 7 and the internal cavity of the sealing airbag 10 through the multiple first air holes 17. The movable push plate 5 has buckle grooves 16 on both sides that are adapted to the buckle 14. When the movable push plate 5 moves towards the fixing pad 4, the two buckle 14 on the front side of the fixing pad 4 deform and are stuck on the front side of the movable push plate 5, thereby preventing the movable push plate 5 from resetting and keeping the storage airbag 7 in a continuously compressed state.

[0020] One end of the air outlet pipe 6 is connected to the output end of the compressor pump inside the atomizer main unit 1 via a flexible hose. An annular sealing groove 18 is formed along the contour of the front side of the air outlet pipe 6, providing a sealing base for the connection between the sleeve 8 and the air outlet pipe 6. A connecting cap 19 is integrally formed at the end of the sleeve 8 opposite to the movable push plate 5, and a positioning ring 20 is integrally formed at the end of the sleeve 8 away from the connecting cap 19. A sealing ring 21 is integrally formed at the end of the positioning ring 20 opposite to the air outlet pipe 6. The connecting cap 19 is threaded onto the fixing ring 15, and the sealing ring 21 is inserted into the sealing groove 18. Multiple second air holes 22 are formed on the bottom surface of the recess 9, and the inner cavity of the sealing airbag 10 is connected to the sealing airbag through the second air holes 22. The sleeve 8 and the first air hole 17 are connected to the inner cavity of the storage airbag 7. When the storage airbag 7 is compressed, the air in the storage airbag 7 will enter the cavity between the sleeve 8 and the air outlet pipe 6 through multiple first air holes 17, and finally enter the sealing airbag 10 through multiple second air holes 22 to inflate the sealing airbag 10. A compression spring is fitted on the outside of the storage airbag 7. One end of the compression spring abuts against the front side of the fixed pad 4, and the other end abuts against the rear side of the movable push plate 5. After the fastener 14 releases the restriction on the movable push plate 5, the rebound force of the compression spring pushes the movable push plate 5 to reset, so that the air in the sealing airbag 10 is recovered into the storage airbag 7.

[0021] A medicine cup connecting tube 11 is inserted and installed on the outside of the sleeve 8. After the sealing airbag 10 expands, it can complete the connection and sealing between the sleeve 8 and the medicine cup connecting tube 11. The static friction force on the connecting end of the medicine cup connecting tube 11 can be released by the contraction of the sealing airbag 10, so that the connecting end of the medicine cup connecting tube 11 can be quickly separated from the sleeve 8.

[0022] It should be noted that this utility model is a nebulizer for thoracic surgery nursing. During nursing operations, the nurse first inserts the medicine cup connecting tube 11 into the outside of the sleeve 8, and then presses the movable push plate 5 towards the fixed pad 4. The movable push plate 5 continuously compresses the storage airbag 7. The gas contained inside the storage airbag 7 is delivered through the first air hole 17 in the movable push plate 5. The airflow passes through the internal cavity of the sleeve 8 and continuously flows into the cavity of the sealing airbag 10 through the second air hole 22 on the bottom surface of the groove 9. When the sealing airbag 10 is filled with gas, it expands radially, tightly adhering to the outer wall of the medicine cup connecting tube 11. The expansion force secures the tubing and seals the assembly gap, preventing leakage of the nebulized airflow. After the movable push plate 5 moves to the designated position, the fastener 14 on the fixed pad 4 elastically deforms and engages with the fastener groove 16, locking the position of the movable push plate 5 and maintaining the storage airbag 7. In the compressed state, the sealing airbag 10 is kept in an inflated and locked state. Therefore, the high-pressure airflow generated by the internal compressor pump of the nebulizer host 1 is continuously delivered to the medicine cup connecting tube 11 through the air outlet tube 6, stably supplying the air source required for nebulization. After the nursing work is completed, the operator pushes the lever buckle 14 to both sides to release the limit constraint, thereby using the compression spring on the outside of the storage air bag 7 to push the movable push plate 5 to complete the reset. The gas inside the sealing air bag 10 flows back to the storage air bag 7, and the sealing air bag 10 gradually contracts, releasing the clamping force on the outer wall of the medicine cup connecting tube 11. The nursing staff can easily pull out the medicine cup connecting tube 11 without pulling the tube forcefully, reducing the probability of tube deformation and damage.
