Description

Technical Field

[0001] The utility model relates to the technical field of atomizer adapters, in particular to an atomizer adapter. Background Art

[0002] Nebulizer inhalation therapy is an important and effective treatment method for respiratory diseases. It uses a nebulizer to atomize the liquid medicine into tiny particles. The medicine enters the respiratory tract and is deposited in the lungs through breathing, thus achieving the purpose of painless, rapid and effective treatment. Nebulizer inhalation therapy requires the use of a nebulizer.

[0003] The patent with announcement number CN207654500U discloses an oxygen supply adapter for an oxygen nebulizer, which includes: a cavity, a first port, a second port, and a third port; the first port is used to connect an oxygen source; the first port is formed as a tube body, and its outer periphery is in airtight contact with the inner wall of the cavity; the tube body can slide in the cavity; the second port is used to connect the oxygen connector of the oxygen nebulizer to provide oxygen to the oxygen nebulizer for atomization; the third port is used to connect a nasal catheter to provide oxygen to the user through the nasal catheter so that the user can inhale oxygen; when the tube body is inserted into a predetermined position of the cavity, the tube body partially or completely closes the third port, thereby adjusting the ventilation volume of the third port.

[0004] However, nebulizer adapters such as the above are not applicable because different instruments or adapters have certain tube diameters. Conventional nebulizers (the interface is too large) are not tightly connected when patients on ventilators are stopped for nebulization (the endotracheal tube interface is smaller than the nebulizer interface). In addition, the pediatric ventilator pipeline (the interface is too small) cannot be connected to a conventional nebulizer, which causes inconvenience to medical staff during the actual medical process and delays the patient's condition. Utility Model Content

[0005] The purpose of the utility model is to provide a nebulizer adapter, which overcomes the problem in the prior art that the nebulizer adapter has different sizes of interfaces of different types of nebulizers or adapters, resulting in a loose connection or failure to connect the two, which in turn brings many inconveniences to medical staff and delays the patient's condition.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0007] An atomizer adapter is designed. The conical interface can meet the connection of any interface pipeline, so that it can be tightly connected. At the same time, the anti-dropping piece can be opened to prevent the connected pipeline from accidentally detaching, and the tightness of the connection is strengthened, making it more suitable for the connection of different models of pipelines. The specific plan is as follows:

[0008] An atomizer adapter, comprising an adapter body, and three through pipes arranged in different directions on the adapter body, wherein the three through pipes are respectively connected with a conical interface;

[0009] At least two anti-dropping parts are equidistantly arranged on the conical interface for abutting against the inner side of the connecting pipeline;

[0010] A retracting mechanism is arranged in the conical interface, one end of the retracting mechanism is connected to the spreading anti-dropping component, and the other end of the retracting mechanism is connected to a driving rod.

[0011] Preferably, the conical interface is a tubular structure with an outer diameter that gradually decreases from the inside to the outside, and the expansion anti-dropping member is connected to the tube mouth of the conical interface.

[0012] Preferably, the expansion anti-dropping member comprises a movable end and an abutting end, and one end of the movable end is hinged at the conical interface pipe mouth;

[0013] The other end of the movable end is connected to the abutting end, and the angle between the abutting end and the movable end is an acute angle;

[0014] An anti-slip barb is arranged on the outer side of the abutting end, and the anti-slip barb is inclined toward the free end of the abutting end.

[0015] Preferably, the retracting mechanism comprises a guide slide rod, a return spring and a movable rod, the guide slide rod is slidably connected to the inner side of the conical interface through a fixed block, and one end of the guide slide rod is connected to the driving rod;

[0016] The guide slide rod is provided with a spring baffle plate located outside the fixed block, and the return spring is arranged between the fixed block and the spring baffle plate;

[0017] There are two movable rods, one end of the two movable rods is hinged to the other end of the guide slide rod, and the other end is respectively hinged to the two support anti-dropping parts.

[0018] Preferably, the lower end of the driving rod passes through the through pipe and is hinged with a connecting rod, and the connecting rod is hinged with the guide slide rod;

[0019] A sealing gasket is provided at the sliding connection between the driving rod and the through pipe.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model adopts a conical interface on the three-way atomizer adapter body, which can ensure that connecting pipes of different diameters can be connected to the conical interface, avoiding the problem of insufficient connection or failure to connect between different types of connecting devices due to different diameters, thereby improving the applicability of the atomizer adapter.

[0022] 2. The utility model is provided with a propping anti-dropout member at the conical interface, which can abut against the pipe connected to the adapter inside, thereby improving the firmness of the connection by increasing the friction force. At the same time, an anti-dropout barb is also provided to further improve the tightness of the connection. When the connected pipe tends to be pulled outward, the friction effect of the propping anti-dropout member will be more significant, so that the connected pipe will not be easily detached.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present invention.

[0035] like Figure 1-6 As shown, the utility model provides a nebulizer adapter, including an adapter body 1, and three through pipes 11 arranged in different directions on the adapter body 1, so as to connect the nebulizer and other instruments through the connecting pipes, thereby realizing oxygen supply to the patient. The three through pipes 11 are respectively connected with a conical interface 2, which can be used to connect pipelines of different diameters and ensure the tightness of the connection to avoid leakage. At least two expansion and anti-slipping parts 3 for abutting against the inner side of the connecting pipeline are equidistantly arranged on the conical interface 2. The expansion and anti-slipping parts 3 can not only ensure the tightness of the connection between the connecting pipeline and the conical interface 2, but also prevent the connection from loosening. A retraction mechanism 4 is arranged in the conical interface 2, one end of the retraction mechanism 4 is connected to the expansion and anti-slipping part 3, and the other end of the retraction mechanism 4 is connected to a driving rod 5, and the retraction mechanism 4 can be driven by the driving rod 5 to control the opening and closing of the expansion and anti-slipping part 3.

[0036] In the above solution, the conical interface 2 is a tubular structure with an outer diameter gradually decreasing from the inside to the outside, and the expansion anti-dropping member 3 is connected to the pipe mouth of the conical interface 2.

[0037] As an optimization technical solution of the utility model, the pipeline structure of the conical interface 2 gradually shrinks from the inside to the outside, which can ensure that connecting pipes of different diameters can be connected to the conical interface 2, and the tightness of the connection is ensured by opening the anti-dropping piece 3. At the same time, it can also prevent the connection from falling off, which is of great significance in actual use.

[0038] In the above scheme, the support anti-slip component 3 includes a movable end 31 and an abutting end 32. One end of the movable end 31 is hinged at the pipe mouth of the conical interface 2, and the other end of the movable end 31 is connected to the abutting end 32. The angle between the abutting end 32 and the movable end 31 is an acute angle. An anti-slip hook 321 is provided on the outer side of the abutting end 32, and the anti-slip hook 321 is inclined toward the free end of the abutting end 32.

[0039] As an optimized technical solution of the utility model, the abutting end 32 can be separated from or abutted against the inner wall of the connecting tube of other connected instruments by swinging the movable end 31 inward or outward. When swinging inward to separate, the connecting tube to be connected can be easily inserted into the conical interface 2, and when swinging outward to abut, it can tightly abut against the inner wall of the connected connecting tube to avoid loosening at the connection between the connecting tube and the conical interface 2. At the same time, the anti-detachment barb 321 will exert a reaction force when the connected connecting tube tends to detach or is pulled outward by external force, so as to avoid the connecting tube from being easily pulled off, and also make the abutting end 32 abut more tightly, thereby making it more difficult for the connecting tube to detach.

[0040] In the above scheme, the retraction mechanism 4 includes a guide slide rod 7, a reset spring 8 and two movable rods 9. The guide slide rod 7 is slidably connected to the inner side of the conical interface 2 through a fixed block 21. One end of the guide slide rod 7 is connected to the driving rod 5. The guide slide rod 7 is provided with a spring baffle 71 located on the outside of the fixed block 21. The reset spring 8 is arranged between the fixed block 21 and the spring baffle 71. One end of the two movable rods 9 is hinged to the other end of the guide slide rod 7, and the other end is hinged to the two open anti-slip parts 3 respectively.

[0041] As an optimized technical solution of the utility model, when the guide slide rod 7 slides inward, it will pull the anti-slipping part 3 back through the movable rod 9 to facilitate the removal or insertion of connecting pipes with different diameters. When the guide slide rod 7 slides outward, it will push the anti-slipping part 3 to be opened through the movable rod 9, and fix the connecting pipe from the inside. The reset spring 8 ensures that the anti-slipping part 3 is always in the opened state in the absence of external interference, and then it can have abutment effect on the connecting pipe when the connecting pipe is connected, thereby improving the tightness of the connection.

[0042] In the above scheme, the lower end of the driving rod 5 passes through the through pipe 11 and is hinged with a connecting rod 51 , the connecting rod 51 is hinged with the guide slide rod 7 , and a sealing gasket 6 is provided at the sliding connection between the driving rod 5 and the through pipe 11 .

[0043] As an optimization technical solution of the utility model, by pulling the driving rod 5, the guide sliding rod 7 can be pulled inward through the connecting rod 51, thereby achieving the recovery effect of the anti-slip component 3; and the sealing gasket 6 is to ensure the sealing of the adapter body 1 to prevent gas leakage during the sliding process of the driving rod 5.

[0044] Specific implementation cases:

[0045] When the nebulizer adapter is to be connected to the nebulizer and other instruments, first pull the driving rod 5, pull the guide sliding rod 7 to slide inward through the connecting rod 51, and then pull the anti-slip component 3 inward through the movable rod 9. At that time, the connecting pipe to be connected can be inserted toward the conical interface 2 so that the connecting pipe is inserted on the conical interface 2. Release the driving rod 5, and the guide sliding rod 7 slides outward under the restoring elastic force of the reset spring 8, and then the anti-slip component 3 is opened through the movable rod 9 so that it rests on the inner side of the connecting pipe, thereby reinforcing and tightening the connecting pipe inserted on the conical interface 2.

[0046] In this way, the connecting tubes of different instruments can be connected to different through tubes 11 of the adapter body 1, so as to realize oxygen supply to the patient. At the same time, in actual use, due to the presence of the anti-detachment hook 321, the connecting tube will not be detached from the conical interface 2 regardless of accidental or manual pulling. On the contrary, the anti-detachment component 3 will be more tightly abutted, resulting in a tighter connection between the connecting tube and the conical interface 2.

[0047] If the connecting tube is to be removed, the driving rod 5 can be pushed outward, and the anti-dropping member 3 is retracted inward under the drive of the retraction mechanism 4, so that the connection between the connecting tube and the conical interface 2 loses its reinforcement and tightness effect and is easily disengaged.

[0048] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
