Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an inflatable supported atomizing device. Background Art

[0002] At present, the nebulizers used for bedridden patients who cannot move are the same as those used for patients with normal mobility, both of which are composed of a single-lumen connecting tube, a detachable nebulizer mask and a nebulizer cup.

[0003] When a conventional nebulizer is in an upright position, the oxygen from below can fully disperse the atomized medicine in the nebulizer cup. However, when the nebulizer is in an inclined or horizontal position, the medicine in the nebulizer cup is often unable to be fully dispersed. Even when the tilt angle is large, the atomized medicine will flow out of the nebulizer cup. This causes some bedridden patients to be unable to get sufficient atomized gas, affecting the treatment effect.

[0004] While working in the ICU, it was found that bedridden comatose patients were in a supine position and unable to hold the nebulizer, resulting in insufficient nebulization or leakage of nebulized drug. Clinical workers often need to stay beside the nebulized patients for a long time to assist in holding the device, resulting in a waste of medical resources. Summary of the invention

[0005] The invention discloses an inflatable support type atomizing device, aiming to solve the technical problems existing in the prior art.

[0006] The present invention adopts the following technical solutions: An inflatable support type atomizing device comprises an airway unit and a support air cushion unit which are connected to each other; The airway unit includes an air source connecting pipe, an expandable pipe, and an airbag inflation pipe and an atomization channel respectively extending from the expandable pipe, the airbag inflation pipe is connected to the supporting air cushion unit, and the atomization channel is connected to the atomization cup; The support air cushion unit comprises a support air cushion located at the upper part and a base located at the bottom, and the support air cushion is provided with an atomizer cup placement hole for placing the atomizer cup; It also includes a controller, which is connected to a pressure sensor placed in the airbag inflation pipeline, so that when the pressure sensor reaches a preset value, the controller controls the pressure in the airbag inflation pipeline to stop increasing.

[0008] In some embodiments, the diameters of the airbag inflation pipe and the atomization channel are both d, and the diameter D of the expansion pipe should satisfy: D≥4d.

[0012] In some embodiments, the supporting air cushion includes a right-angled trapezoidal portion at the upper end and a square portion at the lower end, the right-angled trapezoidal portion has an inclined surface with a vertical nebulizer cup placement hole, and the square portion has an upper edge with a recess; the vertical center plane passing through the nebulizer cup placement hole at the lowest point on the inclined surface also passes through the vertical center plane of the recess, so that when the patient places his chin on the recess, the nebulizer mask just covers the patient's face.

[0013] In some embodiments, the right-angled trapezoidal portion is further provided with an inner groove for accommodating the atomization channel, and the inner groove is communicated with the edge of the atomization cup placement hole.

[0015] In some embodiments, the air source connecting tube, the expansion pipe, the airbag inflation pipe, and the atomization channel are all made of high-strength medical silicone material; the supporting air cushion is a multi-layer nested structure, which includes, from the outside to the inside, a protective layer of a polyester fiber composite material with good wear resistance and weather resistance, a supporting layer woven from high-strength polyamide fibers, and an airtight layer made of high-barrier butyl rubber. Beneficial Effects

[0016] The present invention discloses an inflatable support type atomizing device. Compared with the prior art, the present invention has the following advantages: The inflatable supported atomizer device of the present invention can effectively support the atomizer cup to prevent the atomized medicine liquid in the atomizer cup from spilling out, and can also fully disperse the atomized medicine liquid, so that the atomized medicine liquid is fully utilized, so that the patient obtains a good treatment effect; for patients who are bedridden for a long time and need atomization, the present invention can effectively avoid the difficulty of the patient in operating a handheld atomizer due to upper limb movement disorders, and reduce the possibility of injury to the patient caused by the handheld atomizer; the present invention is connected by setting a controller and a pressure sensor placed in the airbag inflation pipeline.

Therefore, they cannot be understood as limitations on the present invention.

[0021] like Figure 1 - Figure 7 As shown, the technical solution of the present invention: An inflatable supported atomizer device, comprising an airway unit 1 and a supporting air cushion unit 4 connected to each other; the airway unit 1 comprises an air source connecting pipe 11, an expandable pipe 12, and an airbag inflation pipe 13 and an atomization channel 14 respectively extending from the expandable pipe 12, the airbag inflation pipe 13 is connected to the supporting air cushion unit 4, and the atomization channel 14 is connected to the atomization cup 8; The support air cushion unit 4 includes a support air cushion 41 located at the upper part and a base 42 located at the bottom. The support air cushion 41 is provided with an atomizer cup placement hole 413 for placing the atomizer cup 8. It also includes a controller 6, which is connected to a pressure sensor 5 placed in the airbag inflation pipe 13, so that when the pressure sensor 5 reaches a preset value, the controller 6 controls the air pressure in the airbag inflation pipe 13 to continue to increase.

[0022] The first preferred embodiment disclosed by the present invention is as follows Figure 1-Figure 6 As shown: An inflatable supported atomizing device comprises an air passage unit 1 and a supporting air cushion unit 4 which are connected to each other.

[0023] The ventilation channel unit 1 includes a connected air source connecting pipe 11, an expandable pipe 12, and an airbag inflation pipe 13 and an atomization channel 14 respectively extending from the expandable pipe 12; an air intake switch 111 is installed on the air source connecting pipe 11, and the controller 6 is connected to the air intake switch 111 to realize the connection and disconnection between the air source connecting pipe 11 and the oxygen source.

[0024] The airbag inflation pipe 13 is communicated with the supporting air cushion unit 4 via an inflation pipe interface 412 , and the atomization channel 14 is communicated with a vent nozzle (not shown) at the middle of the bottom wall of the atomization cup 8 .

[0025] The expansion pipe 12 is divided into a first chamber 122 and a second chamber 123 by a partition wall 121 .

[0026] The partition wall 121 is located on the vertical center plane of the expansion pipe 12, and extends upward from the bottom wall to form a semicircular partition wall 121. The first chamber 122 and the second chamber 123 lead to the airbag inflation pipe 13 and the atomization channel 14 respectively. Under the separation of the partition wall 121, the gas in the first chamber 122 and the second chamber 123 automatically flows to the airbag inflation pipe 13 and the atomization channel 14 respectively, and the gas flow is smoother.

[0027] The diameters of the gas source connecting tube 11, the airbag inflation pipe 13 and the atomization channel 14 are all d, and the diameter D of the expansion pipe 12 should satisfy: D≥4d; d is 2-3mm, D is 8-12mm.
