Description

Technical fields:

[0001] This utility model relates to the field of medical devices, specifically to a universal reducing connector for artificial airways. Background technology:

[0002] Patients with respiratory failure whose pathophysiological abnormalities such as hypoxia, carbon dioxide retention, and acidosis continue to worsen despite oxygen therapy and medication are in need of resuscitation, may require the establishment of an artificial airway.

[0003] An artificial airway is an artificial gas passage established by inserting various tubes through the upper respiratory tract into the pharynx or directly into the trachea. After the artificial airway is established, it is usually connected to medical equipment such as a ventilator, oxygen source (high-pressure pipeline oxygen / oxygen generator), nebulizer, etc. Because the tubes of the artificial airway and medical equipment such as ventilators are different brands, the interface diameters of the tubes and medical equipment may not be completely compatible, which can easily lead to failure to connect, loose connection, tube detachment, and air leakage, directly affecting the effectiveness of the medical equipment.

[0004] In view of this, there is an urgent need to design a connector that can solve the problem of tight connection between connectors of different diameters at any time, in one step, without the need to switch between multiple connectors, to minimize airway dead space ventilation, and to help various medical devices play their maximum therapeutic role. Utility Model Content:

[0005] The purpose of this invention is to provide a universal reducing connector for artificial airways.

[0006] This utility model is implemented by the following technical solution:

[0007] A universal reducing connector for artificial airways includes a main sleeve, with multiple auxiliary sleeves respectively provided inside both ends of the main sleeve. The diameters of the multiple auxiliary sleeves at any end of the main sleeve gradually decrease, and the multiple auxiliary sleeves are arranged by the larger diameter auxiliary sleeve being sleeved on the smaller diameter auxiliary sleeve.

[0008] A spacer ring is fixedly fitted in the middle of the main sleeve, and limit nuts are screwed onto the main sleeve on both sides of the spacer ring.

[0009] The ends of the multiple auxiliary sleeves at any end of the main sleeve are respectively fixed with L-shaped connecting rods. The end of the main sleeve is arranged with grooves corresponding to the L-shaped connecting rods at intervals along the circumference. The end of each L-shaped connecting rod is placed in the groove and the end of the L-shaped connecting rod is screwed to the limiting nut.

[0010] Preferably, the plurality of secondary sleeves within one end of the main sleeve abut against the ends of the plurality of secondary sleeves of the same diameter within the other end of the main sleeve.

[0011] Preferably, the end of the L-shaped connecting rod is provided with a protrusion.

[0012] The advantages of this invention are as follows: Artificial airway tubes, ventilators, and other medical device connectors are inserted into different auxiliary tubes at both ends of the main tube to achieve the function of connecting tubing. By removing and retaining auxiliary tubes of different diameters, the diameter of both ends of the main tube can be changed, facilitating the connection of connectors for medical devices of different diameters. After the limiting nut rotates and moves, it is fitted onto the L-shaped connecting rod, and through threaded limiting, it prevents each auxiliary tube from falling out of the main tube. When using an artificial airway tube, it can prevent it from being unintentionally pulled out by the patient. Attached image description:

[0018] 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.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, a universal reducing connector for artificial airways includes a main sleeve 1, with multiple auxiliary sleeves 2 respectively provided inside both ends of the main sleeve 1. The diameter of the multiple auxiliary sleeves 2 at any end of the main sleeve 1 gradually decreases. The multiple auxiliary sleeves 2 are arranged by a larger diameter auxiliary sleeve 2 being fitted onto a smaller diameter auxiliary sleeve 2. The thickness of the multiple auxiliary sleeves 2 is preferably 1 mm. The main sleeve 1 and auxiliary sleeves 2 are made of materials commonly used in medical devices, such as polyethylene, polypropylene, and polyvinyl chloride.

[0020] Connectors for medical devices such as artificial airway tubes and ventilators are inserted into different auxiliary tubes 2 at both ends of the main tube 1 to achieve the function of connecting the tubing. By removing and retaining auxiliary tubes 2 of different diameters, the diameter of both ends of the main tube 1 can be changed, which is conducive to adapting to the connection of connectors for medical devices of different diameters.

[0021] A spacer ring 3 is fixedly fitted in the middle of the main sleeve 1. Limiting nuts 4 are screwed onto the main sleeve 1 on both sides of the spacer ring 3. The limiting nuts 4 limit the two limiting nuts 4 to prevent them from moving in the same direction.

[0022] Multiple auxiliary sleeves 2 at any end of the main sleeve 1 are respectively fixed with L-shaped connecting rods 5. Since the multiple auxiliary sleeves 2 are connected sequentially, the thickness of each auxiliary sleeve 2 from the end to the main sleeve 1 is different. Therefore, the lengths of the multiple L-shaped connecting rods 5 and the corresponding auxiliary sleeves 2 are different. The end of the main sleeve 1 is arranged with grooves 6 corresponding to the L-shaped connecting rods 5 at intervals along the circumference. The end of each L-shaped connecting rod 5 is placed in the groove 6 and is flush with the outer surface of the main sleeve 1. The end of the L-shaped connecting rod 5 is screwed to the limiting nut 4. After the limiting nut 4 is rotated and moved, it is also sleeved on the L-shaped connecting rod 5. Through the threaded limit, each auxiliary sleeve 2 is prevented from coming out of the main sleeve 1.

[0023] Multiple auxiliary sleeves 2 inside one end of the main sleeve 1 abut against the ends of multiple auxiliary sleeves 2 of the same diameter inside the other end of the main sleeve 1.

[0024] The L-shaped connecting rod 5 has a protrusion 7 at its end. The protrusion 7 can prevent the limiting nut 4 from rotating out. At the same time, the fingernail-shaped protrusion 7 can be used to pull the auxiliary sleeve 2 out of the main sleeve 1.

[0025] Working principle: In use, different L-shaped connecting rods 5 can be marked with the corresponding diameter of the secondary sleeve 2 (not shown in the figure). The limiting nut 4 rotates and moves backward, away from the L-shaped connecting rod 5. According to the connector requirements of the pipeline, multiple secondary sleeves 2 at both ends of the main sleeve 1 are pulled out, and the secondary sleeve 2 of the required diameter is retained. Then, the artificial airway tube and medical equipment are connected by inserting them into the secondary sleeves 2 at both ends of the main sleeve 1. The limiting nut 4 rotates and moves forward, returning to the L-shaped connecting rod 5. Through threaded limiting, the secondary sleeve 2 and the connected connector are prevented from coming out of the main sleeve 1.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
