Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical atomizing component. Background Technology

[0002] A medical nebulizer is a medical device that atomizes liquid medicine into tiny particles and inhales the medicine into the respiratory tract and lungs through breathing, thereby treating acute and chronic respiratory diseases.

[0003] Currently, the connection process between the nebulizer and the nebulization tubing (the tube connecting the ventilator and the patient's nasal cavity) during nebulization therapy is as follows: remove the sealing cap from the nebulization tubing—thread the nebulizer connector to the nebulization tubing—remove the nebulizer after nebulization—reseal the interface on the nebulization tubing with the sealing cap again. Between removing the sealing cap from the nebulization tubing—threading the nebulizer connector to the nebulization tubing, and after nebulization—reseal the interface on the nebulization tubing with the sealing cap again, the interface on the nebulization tubing is open, posing a risk of contamination and splashing of the nebulized medication. Utility Model Content

[0004] The purpose of this invention is to provide a medical nebulizer assembly to solve the technical problems in the prior art where the installation and removal of nebulizers are cumbersome, and the nebulizer tubes are left open for a long time, posing risks of contamination and splashing of nebulized medication.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides a medical nebulizer assembly, including a connecting tube and an adapter that are fixedly connected and interconnected. The adapter is used to connect to the nebulizer, and both ends of the connecting tube are used to insert the nebulizer tube.

[0006] The adapter is configured as a stepped tube with a convex cross-section, and the end with the smaller diameter is away from the connecting pipe;

[0007] The adapter has a spring and a plug arranged sequentially in the direction away from the connecting pipe. The plug has an annular inclined surface in the circumferential direction, and the annular inclined surface can abut against the bend of the adapter under the elastic force of the spring to seal the adapter.

[0008] The connector of the atomizer can be fixedly connected to the adapter and the plug is pressed inward. The plug or the connector has a notch on the opposite side so that the atomizing reagent can enter the connecting tube.

[0009] As a preferred embodiment of this utility model, the plug is cylindrical on the side near the connecting tube and frustum-shaped on the side away from the connecting tube, and the annular inclined surface is the annular surface of the frustum.

[0010] The stopper comprises a rigid inner core and an outer rubber layer.

[0011] As a preferred embodiment of this utility model, an annular mounting platform is provided inside the adapter on the side near the connecting tube, and the upper and lower ends of the spring are respectively fixedly connected to the lower end of the plug and the upper end of the mounting platform.

[0012] The cylindrical part of the plug is slidably connected to the inner wall of the adapter, and a through hole is provided in the circumferential direction of the cylindrical part.

[0013] As a preferred embodiment of this utility model, the adapter is provided with an internal thread on the side away from the connecting tube, and the connector of the atomizer is provided with an external thread.

[0014] As a preferred embodiment of this utility model, the end of the adapter away from the connecting pipe is equipped with an openable and closable cover.

[0015] As a preferred embodiment of this utility model, the two ends of the connecting tube are provided with annular guide bevels so as to be inserted into the atomizing tube.

[0016] As a preferred embodiment of this utility model, limit rings are symmetrically provided on the outer walls of both sides of the connecting tube to prevent the atomizing tube from being over-inserted;

[0017] An elastic sealing layer is wrapped around the outer wall of the connecting pipe between the limiting ring and the corresponding end.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] During nebulization, the atomizer connector is securely connected to the adapter. At this time, the connector pushes the plug towards the connecting tube. The connector installation and adapter opening are synchronized, ensuring no open gaps in the atomizing tube and reducing the risk of contamination. After nebulization, the atomizer connector is removed from the adapter. The connector no longer pushes the plug, and the plug springs back, resealing the adapter. The adapter removal and sealing are synchronized, again ensuring no open gaps in the atomizing tube, reducing the risk of contamination and preventing liquid splashing. Attached Figure Description

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model specifically provides a medical nebulizer assembly, including a connecting tube 1 and an adapter 2 that are fixedly connected and interconnected. The adapter 2 is used to connect to the nebulizer, and both ends of the connecting tube 1 are used to insert nebulizer tubes 3.

[0031] The adapter 2 is configured as a stepped tube with a convex cross-section, and the smaller diameter end is away from the connecting pipe 1;

[0032] Inside the adapter 2, a spring 4 and a plug 5 are sequentially arranged along the direction away from the connecting pipe 1. The plug 5 has an annular inclined surface 6 in the circumferential direction, and the annular inclined surface 6 can abut against the bend 7 of the adapter 2 under the elastic force of the spring 4 to seal the adapter 2.

[0033] The connector 8 of the nebulizer can be fixedly connected to the adapter 2 and the plug 5 is pressed inward. The plug 5 or the connector 8 has a notch 9 on the opposite side so that the nebulizing reagent can enter the connecting tube 1.

[0034] Both ends of the connecting tube 1 are normally connected to the atomizing tube 3. When atomization is needed, the connector 8 of the atomizer is fixedly connected to the adapter 2 (using various methods such as snap-fit, threaded connection, or plug-in). At this time, the connector 8 can squeeze the plug 5 towards the connecting tube 1, causing the plug 5 to move inward against the elastic force of the spring 4. This releases the contact between the annular inclined surface 6 of the plug 5 and the bend of the adapter 2, thus releasing the seal between the plug 5 and the adapter 2. At the same time, because the connector 8 has a notch 9, even if the connector 8 and the adapter 2 are in contact, the atomizing gas can pass through the notch 9 and enter the connecting tube 1 and the atomizing tube 3 sequentially.

[0035] After the nebulization treatment is completed, remove the connector 8 of the nebulizer from the adapter 2. The connector 8 will no longer squeeze the plug 5. The plug 5 can rebound under the elastic force of the spring 4, so that the annular inclined surface 6 abuts against the bend 7 of the adapter 2, thereby sealing the adapter 2 and keeping the pipeline formed by the connecting tube 1 and the nebulization tube 3 in a sealed state to prevent external air from contaminating the nebulization tube 3.

[0036] In summary, during atomization, the connector 8 of the atomizer is fixedly connected to the adapter 2. At this time, the connector 8 can squeeze the plug 5 towards the connecting tube 1. The installation of the connector 8 and the opening of the adapter 2 are carried out simultaneously, and there is no open gap in the atomization tube, reducing the risk of contamination. After atomization, the connector 8 of the atomizer is removed from the adapter 2. The connector 8 no longer squeezes the plug 5, and the plug 5 can rebound under the elastic force of the spring 4, resealing the adapter 2. The removal of the adapter 8 and the sealing of the adapter 2 are carried out simultaneously, and there is no open gap in the atomization tube, reducing the risk of contamination and avoiding splashing of the atomized medicine.

[0037] It should be noted that if the notch 9 is opened on the connector 8 of the atomizer, after the connector 8 is fixedly connected to the adapter 2, the notch 9 should enter the space with a larger diameter at the bottom of the adapter 2, so as to avoid the smaller diameter part at the top of the adapter 2 from obstructing the flow of the atomizing gas.

[0038] If the notch 9 is located at the end of the plug 5, the lateral depth of the notch 9 should be greater than the wall thickness of the connector 8 to prevent the end of the connector 8 from blocking the notch 9.

[0039] Furthermore, the plug 5 is cylindrical on the side near the connecting tube 1 and frustum-shaped on the side away from the connecting tube 1, with the annular inclined surface 6 being the annular surface of the frustum. The cylindrical bottom facilitates connection with the spring 4. When not atomizing, the spring 4 applies an elastic thrust to the plug 5, causing the annular surface of the frustum to abut against the bend, sealing the adapter 2.

[0040] The stopper 5 consists of a rigid inner core and an outer rubber layer. The rigid inner core can be made of plastic or other lightweight rigid materials; the rubber layer is elastic and can deform when it comes into contact with a bend, resulting in a better seal.

[0041] Furthermore, an annular mounting platform 10 is provided inside the adapter 2 on the side near the connecting tube 1, and the upper and lower ends of the spring 4 are fixedly connected to the lower end of the plug 5 and the upper end of the mounting platform 10, respectively.

[0042] Spring 4 can be set as one large spring 4 or multiple small springs 4. The diameter of the large spring 4 is approximately equal to the diameter of the mounting platform 10, while the diameter of the small springs 4 is much smaller than the diameter of the large spring 4. Multiple small springs 4 can be evenly set on the mounting platform 10.

[0043] In order to better constrain the movement path of the plug 5 and prevent the plug 5 from shaking from side to side and affecting the sealing effect, the cylindrical part of the plug 5 is slidably connected to the inner wall of the adapter 2, that is, the diameter of the cylindrical part is approximately equal to the diameter of the inner wall of the adapter 2; at this time, in order to allow the atomizing gas to enter the atomizing tube 3 normally, a through hole 11 is provided in the circumferential direction of the cylindrical part.

[0044] Furthermore, the adapter 2 has an internal thread on the side away from the connecting tube 1, and the atomizer connector 8 has an external thread. During atomization, the connector 8 is threadedly connected to the adapter 2. During this process, the end face of the connector 8 continuously approaches the end face of the plug 5, and finally abuts against and squeezes the plug 5, causing the plug 5 to release the seal on the adapter 2.

[0045] Furthermore, the end of the adapter 2 away from the connecting tube 1 is equipped with an openable and closable cover 12, that is, one end of the cover 12 is hinged to the adapter 2. When not atomizing, the cover 12 can be closed to keep the inner wall of the adapter 2 clean.

[0046] Furthermore, since the connecting tube 1 is inserted into the atomizing tube 3, and the opening of the atomizing tube 3 is elastic, in order to maintain a seal, the inner diameter of the atomizing tube 3 should be slightly smaller than the outer diameter of the connecting tube 1. Therefore, the two ends of the connecting tube 1 are provided with annular guide slopes 13. The diameter of the guide slopes 13 gradually increases, with the smallest point being smaller than the inner diameter of the atomizing tube 3 and the largest point being equal to the outer diameter of the connecting tube 1, so as to allow for insertion into the atomizing tube 3.

[0047] Furthermore, limit rings 14 are symmetrically provided on the outer walls of both sides of the connecting tube 1 to prevent the atomizing tube 3 from being over-inserted;

[0048] An elastic sealing layer is wrapped around the outer wall of the connecting pipe 1 between the limiting ring 14 and the corresponding end.

[0049] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
