Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anti-loosening nebulizer connection device. Background Technology

[0002] Nebulization is a treatment method that delivers medications in aerosol form to the respiratory tract and lungs through inhalation. It has advantages such as direct delivery of medications to the lungs, good local therapeutic effect, rapid symptom relief, reduced drug dosage, and ease of use.

[0003] To avoid cross-infection, existing nebulizers use disposable tubing to deliver atomized gas. However, these tubings are usually simply plugged into the nebulizer tube. Due to the smooth inner wall of the tubing, they are prone to detachment under external force during actual use. To avoid this, a non-loosening nebulizer connection device is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised by the prior art by proposing an anti-loosening atomizer connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nebulizer connection device for preventing loosening includes a nebulizer, an air outlet pipe fixedly connected to the surface of the nebulizer, a positioning sleeve fixedly fitted onto the surface of the air outlet pipe, a connecting pipe fixedly connected to the surface of the positioning sleeve, and an anti-loosening mechanism provided on the surface of the positioning sleeve.

[0007] The anti-loosening mechanism includes a fixing ring fixedly connected to the surface of the positioning sleeve, a limit ring slidably connected to the surface of the positioning sleeve, and a return spring sleeved on the surface of the positioning sleeve.

[0008] Preferably, one end of the return spring is fixedly connected to the surface of the fixed ring, and the other end of the return spring is fixedly connected to the surface of the limiting ring.

[0009] Furthermore, the surface of the positioning sleeve is provided with multiple clearance holes, and the inner wall of the clearance holes is slidably connected with a push rod. The push rod is provided with a first inclined surface on the side near the limiting ring.

[0010] Preferably, the limiting ring has a second inclined surface on the side near the first inclined surface, and an anti-slip pad is fixedly connected to the surface of the limiting ring.

[0011] Furthermore, a trapezoidal groove is provided on the surface of the air outlet pipe, and a first rounded corner is provided on the surface of the top rod near the air outlet pipe.

[0012] Preferably, the inner wall of the positioning sleeve is fixedly connected to an installation groove, the inner wall of the installation groove is fixedly connected to an O-ring, and one end of the air outlet pipe is provided with a second rounded corner.

[0013] The beneficial effects of this utility model are as follows:

[0014] During installation, push and press the limiting ring. After the first rounded corner contacts the second rounded corner on the surface of the air outlet pipe, it will cause multiple push rods to move away from each other until the multiple push rods are aligned with the trapezoidal groove. Then, the limiting ring will reset under the action of the return spring, so that the surface of the second inclined surface contacts the surface of the first inclined surface. After the first inclined surface is subjected to force, the multiple push rods will slide closer to each other, so that the surface of the first rounded corner contacts the surface of the trapezoidal groove. The advantage of this is that it prevents the connecting pipe from becoming loose and detached from the atomizer during use, ensuring safe use. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4A non-loosening atomizer connection device includes an atomizer 1, an air outlet pipe 2 fixedly connected to the surface of the atomizer 1, a positioning sleeve 3 fixedly fitted onto the surface of the air outlet pipe 2, a connecting pipe 4 fixedly connected to the surface of the positioning sleeve 3, and a non-loosening mechanism provided on the surface of the positioning sleeve 3.

[0022] The anti-loosening mechanism includes a fixing ring 16 fixedly connected to the surface of the positioning sleeve 3, a limit ring 7 slidably connected to the surface of the positioning sleeve 3, and a return spring 5 sleeved on the surface of the positioning sleeve 3.

[0023] By setting a connecting pipe 4, which connects to an external breathing mask, air is supplied. By setting an air outlet pipe 2, the atomized gas generated by the nebulizer 1 is discharged. By setting a positioning sleeve 3, the insertion and installation with the air outlet pipe 2 is maintained, while the fixing ring 16 and the limiting ring 7 are fixed and kept sliding stably.

[0024] In this utility model, reference Figure 2 One end of the return spring 5 is fixedly connected to the surface of the fixed ring 16, and the other end of the return spring 5 is fixedly connected to the surface of the limit ring 7.

[0025] By setting a reset spring 5, pressure is applied to the limit ring 7 to maintain the stable positioning of the limit ring 7.

[0026] In this utility model, reference Figure 3 The surface of the positioning sleeve 3 is provided with multiple clearance holes 10, and the inner wall of the clearance hole 10 is slidably connected to a push rod 6. The push rod 6 is provided with a first inclined surface 15 on the side near the limiting ring 7.

[0027] By setting the top rod 6, which is engaged with the trapezoidal groove 11 for positioning, the positioning sleeve 3 is prevented from detaching from the air outlet pipe 2. By setting the first inclined surface 15, the top rod 6 is driven to move under force.

[0028] In this utility model, reference is made to Figure 3 The limiting ring 7 has a second inclined surface 9 on the side close to the first inclined surface 15, and an anti-slip pad 8 is fixedly connected to the surface of the limiting ring 7.

[0029] By setting a second inclined surface 9, after it comes into contact with the first inclined surface 15, the compression rod 6 moves. By setting an anti-slip pad 8, friction is increased to prevent slippage when operating the limit ring 7.

[0030] In this utility model, reference Figure 4 The surface of the air outlet pipe 2 is provided with a trapezoidal groove 11, and the surface of the push rod 6 near the air outlet pipe 2 is provided with a first rounded corner 12.

[0031] By setting the trapezoidal groove 11, space is provided for the insertion of multiple push rods 6. By setting the first rounded corner 12, the contact surface between the push rod 6 and the trapezoidal groove 11 is reduced, which facilitates the sliding reset of the push rod 6.

[0032] In this utility model, reference Figure 4 The inner wall of the positioning sleeve 3 is fixedly connected to the mounting groove 14, and the inner wall of the mounting groove 14 is fixedly connected to the O-ring seal 13. One end of the air outlet pipe 2 is provided with a second rounded corner 17.

[0033] By setting the mounting groove 14, space is provided for the installation of the O-ring 13, and the sealing operation is performed by setting the O-ring 13.

[0034] Working principle: When using the atomizer 1, the connecting pipe 4 needs to be connected and fixed to the air outlet pipe 2 first. During installation, push and press the limiting ring 7 to compress the return spring 5, which shortens the spring. After the first rounded corner 12 contacts the second rounded corner 17 on the surface of the air outlet pipe 2, it drives multiple push rods 6 to move away from each other until the multiple push rods 6 correspond to the positions of the trapezoidal groove 11. At this time, the surface of the O-ring seal 13 is pressed against the surface of the air outlet pipe 2. Release the limiting ring 7, and the limiting ring 7 resets under the action of the return spring 5, so that the surface of the second inclined surface 9 contacts the surface of the first inclined surface 15. After the first inclined surface 15 is subjected to force, under the action of pressure, the multiple push rods 6 slide closer to each other, so that the surface of the first rounded corner 12 contacts the surface of the trapezoidal groove 11. Through the above mechanism, the connecting pipe 4 is prevented from being dragged by force, causing the positioning sleeve 3 to separate from the air outlet pipe 2.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
