Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, specifically to a mouthpiece atomizer with a fixed support. Background Technology

[0002] Medical nebulizers, classified as Class II medical devices, can atomize liquid medication into tiny particles. These tiny particles are then inhaled into the respiratory tract and lungs, thereby improving the treatment effect for patients with respiratory diseases.

[0003] Currently, disposable oral nebulizers used in clinical practice, such as Figure 4 As shown, when using the nebulizer, place the mouthpiece directly into the patient's mouth. The patient needs to be awake and cooperate. The patient should hold it in place with their hands. If the patient cannot cooperate with their hands, they need to keep it in their mouth or have a family member hold it in place until the nebulization is finished. The whole process takes about 20 minutes.

[0004] Based on clinical needs, this oral nebulizer is more suitable for most patients than a face mask nebulizer. Face mask nebulizers cover the entire mouth, which can cause runny nose and a feeling of stuffiness, making them unsuitable for some patients. Oral nebulizers offer better comfort and superior nebulization. They are also suitable for a wider range of patients, such as those requiring a supine position after surgery or those who are not fully conscious after general anesthesia. Currently available oral nebulizers do not free the hands; if the hands cannot be fixed and the nebulizer must be held in the mouth for an extended period, prolonged biting can cause significant discomfort. Utility Model Content

[0005] 1. The technical problem to be solved:

[0006] To address the aforementioned technical problems, this utility model provides a mouth-held nebulizer with a fixed support.

[0007] 2. Technical Solution:

[0008] A mouthpiece nebulizer with a fixed support includes a fixed support and a nebulizer body. The nebulizer body has an overall T-shaped structure and includes a mouthpiece, a connecting part, and a nebulizing part. The mouthpiece and the connecting part are movably connected, and the connecting part and the nebulizing part are fixedly connected at a right angle. The fixed support includes a chin rest, which is fixed to the patient's chin by a strap. A hinged telescopic rod is provided above the front end of the chin rest, and a support frame is hinged to the top of the telescopic rod. The support frame is positioned below the neck where the nebulizing part and the connecting part are connected. The telescopic rod needs to overcome significant friction when rotating relative to the chin rest, and the support frame needs to rotate relative to the telescopic rod. Further, the hinge structure of the telescopic rod and the chin rest includes a fixed nut and a sliding sleeve fixedly mounted on the chin rest. A cylindrical first hexagonal nut is slidably and rotatably connected within the sliding sleeve. The first hexagonal nut is fixedly connected to a first rotating shaft, and the telescopic rod is rotatably connected to the first rotating shaft. The first rotating shaft is connected to the fixed nut via an external thread, and a first spring is sleeved on the outside of the first rotating shaft.

[0009] Furthermore, the hinge structure of the telescopic rod and the support frame includes a U-shaped connector fixedly installed at the end of the telescopic rod. One end of the U-shaped connector has a through cylindrical hole, and the other end has an internal threaded hole. A cylindrical second internal hexagonal nut is slidably and rotatably connected in the cylindrical hole. The second internal hexagonal nut is fixedly connected to a second rotating shaft. The support frame is rotatably connected to the second rotating shaft. The second rotating shaft is connected to the internal threaded hole of the U-shaped connector through an external thread. A second spring is sleeved on the outside of the second rotating shaft.

[0010] Furthermore, the telescopic rod includes an outer tube and an inner rod body. The outer tube is also provided with a locking nut, and the inner rod body is slidably connected to the outer tube and the two can be fixed by the locking nut.

[0011] Furthermore, the strap includes an adjustable-length head elastic fixation strap and a neck elastic fixation strap, with the two ends of the neck elastic fixation strap respectively fixed to both sides of the head elastic fixation strap.

[0012] Furthermore, it also includes an arc-shaped silicone plate fitted onto the mouth part of the nebulizer body. When the patient holds the nebulizer body in their mouth, the arc-shaped silicone plate rests against the outside of the patient's mouth. The arc-shaped silicone plate is fixed to the patient's head or an elastic head strap by an elastic connecting band.

[0013] Furthermore, the chin support has an elastic pad on its inner outer ring.

[0014] Furthermore, the chin support is provided with multiple ventilation holes.

[0015] 3. Beneficial effects:

[0016] This invention provides a mouth-held nebulizer with a fixed support. A chin rest is provided to secure it to the patient's chin, and a telescopic rod is hinged to the chin rest. A support frame is hinged to the other end of the telescopic rod. By adjusting the angle and length of the telescopic rod and the angle of the support frame, the support frame can be stably supported on the neck of the nebulizer body. This prevents the nebulizer body from tilting and falling out of the patient's mouth if the patient's jaw is not clenched tightly. Patients using this mouth-held nebulizer with a fixed support can free their hands and do not need to clench the nebulizer body, increasing comfort. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 4 As shown,

[0023] Example 1:

[0024] A mouthpiece atomizer with a fixed support includes a fixed support and an atomizer body 1, such as Figure 4 As shown, the atomizer body 1 has an overall T-shaped structure. The atomizer body 1 includes a mouthpiece 101, a connecting part 102, and an atomizing part 103. The mouthpiece 101 and the connecting part 102 are movably connected, and the connecting part 102 and the atomizing part 103 are fixedly connected at a right angle. Figure 1-3 As shown, the fixed support includes a chin support 2, which is fixed to the patient's chin by a strap 3. A hinged telescopic rod 4 is provided above the front end of the chin support 2. A support frame 5 is hinged to the top of the telescopic rod 4. The support frame 5 is locked below the neck where the atomizing part 103 is connected to the connecting part 102. When the telescopic rod 4 rotates relative to the chin support 2 and the support frame 5 rotates relative to the telescopic rod 4, they need to overcome a large frictional force. That is, after the two rotate relative to each other at a certain angle, they can maintain that angle and withstand a certain force without rotating.

[0025] When using the mouth-mounted nebulizer with a fixed support in this embodiment, the patient first needs to put the nebulizer body in their mouth. The caregiver then fixes the chin support 2 to the patient's chin with the strap 3, adjusts the length of the telescopic rod 4 and its angle relative to the chin support 2, and then adjusts the angle of the support frame 5 to ensure that the support frame 5 is properly supported below the neck where the nebulizer part 103 is connected to the connecting part 102. The length of the telescopic rod 4 is fixed. Due to the support of the support frame 5, the patient does not need to bite down on the nebulizer body to maintain its stability. At this time, the patient or family members do not need to hold the nebulizer body. Specifically, regarding the nebulizer body in this embodiment, its center of gravity is biased towards the chin. When the mouth is not clenched tightly, it easily tilts towards the chin. Furthermore, the atomizing section 103 is connected to a tubing at its tail, which also pulls on that side, easily causing the nebulizer body to tilt towards the chin. Maintaining the stability of the nebulizer body requires a large biting force. The support frame 5 in this embodiment provides support for the nebulizer body, preventing the patient from maintaining a large biting force for extended periods, thus increasing patient comfort. Both the telescopic rod 4 and the support frame 5 need to overcome significant friction when rotating, similar to common mobile phone holders. After rotation, they can maintain their angle and withstand certain external forces, such as the pressure exerted on the nebulizer body when it tilts due to gravity.

[0026] Example 2:

[0027] The hinge structure of the telescopic rod 4 and the chin support 2 includes a fixing nut 6 and a sliding sleeve 7 fixedly mounted on the chin support 2. A cylindrical first internal hexagonal nut 8 is slidably and rotatably connected inside the sliding sleeve 7. The first internal hexagonal nut 8 is fixedly connected to a first rotating shaft 9. The telescopic rod 4 is rotatably connected to the first rotating shaft 9. The first rotating shaft 9 is connected to the fixing nut 6 through an external thread. A first spring 10 is sleeved on the outside of the first rotating shaft 9.

[0028] The first rotating shaft 9 is connected to the fixing nut 6 by an external thread. The deeper it is screwed in, the greater the compression of the first spring 10. At this time, the friction force of the telescopic rod 4 relative to the first rotating shaft 9 is greater. After the telescopic rod 4 rotates, it can maintain the angle and withstand the pressure from the tilt of the atomizer body without rotating.

[0029] Example 3:

[0030] The hinge structure of the telescopic rod 4 and the support frame 5 includes a U-shaped connector 11 fixedly installed at the end of the telescopic rod 4. One end of the U-shaped connector 11 has a through cylindrical hole, and the other end has an internally threaded hole. A cylindrical second hexagonal nut 12 is slidably and rotatably connected in the cylindrical hole. The second hexagonal nut 12 is fixedly connected to a second rotating shaft 13. The support frame 5 is rotatably connected to the second rotating shaft 13. The second rotating shaft 13 is externally threaded to the internally threaded hole of the U-shaped connector 11. A second spring 14 is sleeved on the outside of the second rotating shaft 13. The hinge structure of the telescopic rod 4 and the support frame 5 is similar to the hinge structure between the telescopic rod 4 and the chin support 2, and the working principle is the same, so it will not be described further.

[0031] Example 4:

[0032] The telescopic rod 4 includes an outer tube and an inner rod body, with a locking nut on the outer tube. The inner rod body is slidably connected to the outer tube and the two can be fixed by the locking nut. After fixing, the overall length of the telescopic rod 4 will no longer change.

[0033] Example 5:

[0034] The strap 3 includes an adjustable-length head elastic fixation strap 301 and a neck elastic fixation strap 302, with both ends of the neck elastic fixation strap 302 fixed to both sides of the head elastic fixation strap 301. The head elastic fixation strap 301 and the neck elastic fixation strap 302 work together to make the chin support 2 more securely fixed.

[0035] Example 6:

[0036] A mouthpiece nebulizer with a fixing support further includes an arc-shaped silicone plate 15 fitted onto the mouthpiece 101 of the nebulizer body 1. When the patient holds the nebulizer body 1 in their mouth, the arc-shaped silicone plate 15 rests against the outside of the patient's mouth. The arc-shaped silicone plate 15 is fixed to the patient's head or a head elastic fixing band 301 by an elastic connecting band 16. In this embodiment, the mouthpiece 101 and the connecting part 102 of the nebulizer body 1 are movably fitted together, so they can be disassembled and fitted with the arc-shaped silicone plate. After the arc-shaped silicone plate 15 rests against the outside of the patient's mouth and is fixed by the head elastic fixing band 301, it can prevent the patient from pushing the nebulizer body 1 out with their tongue, and further fixation prevents it from falling out.

[0037] Example 7:

[0038] The chin support 2 has an elastic pad on its inner outer ring and multiple ventilation holes. It is generally made of plastic, making it relatively lightweight. The elastic pad prevents friction against the patient's chin skin, and the ventilation holes ensure breathability while reducing weight.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
