Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, and in particular to a mask elbow plugging and unplugging mechanism. Background Art
[0002] At present, ventilators have been widely used in clinical treatment and hospital rescue. There is no need to insert a tube into the patient's airway through surgery. Instead, a pressure ventilation device and a breathing mask worn on the patient's face are used to deliver a continuous pressure ventilation or a variable pressure ventilation to the patient's airway to treat the patient. In the prior art, a pluggable elbow is usually set on the front of the breathing mask. The elbow is provided with a deformable buckle or other multiple accessories. The deformable buckle on the elbow is inserted at the lower part of the breathing mask interface. The patient dare not forcefully tilt it because he cannot see it. The plugging and unplugging of the elbow requires the cooperation of both hands. Sometimes the strong pressure makes the patient's face uncomfortable. The mask is a consumable that is often replaced or used once, so it is relatively costly to make multiple accessories, which is very wasteful to use. Summary of the invention
[0003] The purpose of the present invention is to provide a mask elbow plugging and unplugging mechanism, aiming to solve the problem in the prior art, so that patients can clearly see how to plug and unplug the elbow, the structure of the deformable hand pressing position and all the buckle positions is simple, and the manufacturing cost is also low.
[0004] The present invention adopts the following technical solution: The present invention provides a mask elbow plug-in and pull-out mechanism, comprising: a breathing mask body, an elbow joint, the breathing mask body is provided with a pipeline interface, the elbow joint comprises an air inlet end and an airway mixing end, the airway mixing end is inserted into the pipeline interface, at least two deformable hand-pressing positions are provided between the outer side surface of the air inlet end and the outer side surface of the airway mixing end, a first buckle position is provided on the outer side of the deformable hand-pressing position, a convex shoulder is provided on the outer periphery of the pipeline interface, a second buckle position is provided on the inner side of the convex shoulder, and the first buckle position and the second buckle position are interlocked.
[0005] Furthermore, the first buckle position and / or the second buckle position is provided with an installation introduction slope.
[0006] Furthermore, the elbow joint is also provided with a limiting shoulder.
[0007] Furthermore, the limit shoulder and the pipeline interface form a downward movement limit, and the first buckle position and the second buckle position can also rotate 360 degrees with each other when they are interlocked.
[0008] Furthermore, the inner diameter of the boss is larger than the inner diameter of the pipeline interface.
[0009] Furthermore, the breathing mask body, the elbow joint and / or the boss and / or the deformable hand-pressing position and / or the first buckle position and / or the second buckle position are transparent.
[0010] The present invention provides a mask elbow plugging and unplugging mechanism. Beneficial effects: The structure of the deformable hand-pressing position and all buckle positions is simple, and the manufacturing cost is also low. The overall mechanism has few accessories and a simple structure, so the manufacturing cost is extremely low, which is very suitable for masks that are consumables that are often replaced or used once; it can also allow patients to clearly see how to plug and unplug the elbow.

[0012] A breathing mask body and an elbow joint, wherein the breathing mask body is provided with a pipeline interface, and the elbow joint includes an air inlet end and an airway mixing end, wherein the airway mixing end is inserted into the pipeline interface, and at least two deformable hand-pressing positions are provided between the outer side surface of the air inlet end and the outer side surface of the airway mixing end, and a first buckle position is provided on the outer side of the deformable hand-pressing position, and a convex shoulder is provided on the outer periphery of the pipeline interface, and a second buckle position is provided on the inner side of the convex shoulder, and the first buckle position and the second buckle position are interlocked. As long as two fingers press the deformable hand-pressing positions on both sides respectively, the first buckle position and the second buckle position can be separated to achieve insertion and extraction. The beneficial effect allows the patient to clearly see at a glance how to insert and extract this elbow, the deformable hand-pressing position and all buckle positions have a simple structure, and the manufacturing cost is also low accordingly, the overall mechanism has few accessories, and the mechanism is simple, so the manufacturing cost is extremely low, which is very suitable for the mask as a consumable material that is frequently replaced or disposable.
[0013] Since the elbow joint is attached with the trachea when the patient uses the breathing mask, when the patient turns over or the trachea placement and extraction direction is changed, since the convex shoulder (B2) of the mask and the second buckle position (T1) are a circle, the first buckle position and the second buckle position can rotate 360 degrees with each other when they are interlocked, so the trachea placement and extraction direction can rotate with the elbow joint. After the first buckle position and the second buckle position are interlocked, the limit shoulder (T3) and the pipeline interface form an up and down movement limit, so the elbow joint can only rotate 360 degrees when in use.
[0014] The inner diameter of the shoulder (ØB) is larger than the inner diameter of the tube interface (ØA). The purpose is to allow the airway mixing end of the elbow to easily pass through the second buckle position and smoothly connect to the mask tube interface.
[0015] The main body of the breathing mask, the deformable hand-pressing position and / or the boss and / or the buckle position are transparent. The purpose is to allow the patient or the user to visually understand the internal insertion and extraction structure of the elbow joint and know how to operate it flexibly and conveniently.
