Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and in particular to an inflatable support type nebulizer. Background Technology

[0002] Currently, the nebulizers used in clinical practice for bedridden patients who cannot move are the same as those used for patients with normal mobility, both consisting of a single-lumen connecting tube, a detachable nebulizing mask, and a nebulizing cup.

[0003] When a conventional nebulizer is in an upright position, the oxygen from below can fully disperse the nebulized medication in the nebulizer cup. However, when the nebulizer is in an inclined or horizontal position, the medication in the nebulizer cup often cannot be fully dispersed. In fact, when the tilt angle is large, the nebulized medication may even flow out of the nebulizer cup. This results in some bedridden patients not receiving sufficient nebulized gas, which affects the treatment effect.

[0004] While working in the ICU, I found that bedridden, comatose patients were unable to hold the nebulizer because they were in a supine position, resulting in insufficient nebulization or leakage of the nebulized medication. Clinicians often had to stay next to the nebulizing patient for a long time to assist in holding the device, which wasted medical resources. Summary of the Invention

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

[0006] The present invention adopts the following technical solution:

[0007] An inflatable support-type atomizing device includes a connected air duct unit and a support air cushion unit.

[0008] The ventilation unit includes a connected air source connection pipe, an expansion pipe, and an airbag inflation pipe and an atomizing channel extending from the expansion pipe. The airbag inflation pipe is connected to the supporting air cushion unit, and the atomizing channel is connected to the atomizing cup.

[0009] The supporting air cushion unit includes a supporting air cushion at the top and a base at the bottom, and the supporting air cushion is provided with an atomizing cup placement hole for placing the atomizing cup.

[0010] It also includes a controller connected to a pressure sensor placed in the airbag inflation tube, such that when the pressure sensor reaches a preset value, the controller controls the pressure in the airbag inflation tube to stop increasing.

[0011] In some embodiments, a semi-circular partition is formed on the vertical center plane of the expansion pipe, extending upward from the bottom wall.

[0012] In some embodiments, the diameter of both the airbag inflation tube and the atomizing channel is d, and the diameter D of the expansion tube should satisfy: D≥4d.

[0013] In some embodiments, a first switch and a second switch for controlling air intake are respectively installed on the airbag inflation pipe and the atomizing channel.

[0014] In some embodiments, the pressure sensor is connected to the controller, and the controller is connected to an alarm, such that when the pressure sensor reaches a preset value, the controller controls the alarm to sound.

[0015] In some embodiments, the pressure sensor is connected to the controller, and the controller is connected to an air inlet switch provided at the air inlet end of the air source connection pipe, so that when the pressure sensor reaches a preset value, the controller controls the air inlet switch to close.

[0016] In some embodiments, the support 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 a vertical atomizing cup placement hole on its inclined surface, and the square portion has a recess on its upper edge. The vertical center plane of the atomizing cup placement hole at the lowest point of the inclined surface also passes through the vertical center plane of the recess, so that when the patient places their chin on the recess, the atomizing mask covers the patient's face.

[0017] In some embodiments, the right-angled trapezoidal portion is further provided with an inner groove for placing the atomizing channel, and the inner groove is connected to the edge of the atomizing cup placement hole.

[0018] In some embodiments, the base includes a seat body surrounded by a bottom wall, side walls, and a top wall. The seat body has an inner cavity, and the top wall has an upper opening. The upper opening is a square shape that matches the square portion, so that when the square portion of the supporting air cushion is inserted into the inner cavity and filled with gas, the square portion expands and is fixed in the seat body within the inner cavity.

[0019] In some embodiments, the air source connection pipe, the expansion pipe, the airbag inflation pipe, and the atomization channel are all made of high-strength medical silicone material; the supporting air cushion has a multi-layer nested structure, which includes, from the outside to the inside, a protective layer of polyester fiber composite material with good wear resistance and weather resistance, a supporting layer woven from high-strength polyamide fiber, and an airtight layer made of high-barrier butyl rubber. Beneficial effects

[0020] This invention discloses an inflatable support-type atomizing device, which has the following advantages compared with the prior art:

[0021] This invention's inflatable support-type nebulizer effectively supports the nebulizer cup, preventing spillage of the nebulized medication and ensuring thorough dispersion and full utilization of the medication for optimal therapeutic effect. For patients requiring nebulization while bedridden, this invention effectively avoids difficulties in operating the nebulizer due to upper limb mobility limitations, reducing the potential for injury. Furthermore, by connecting a controller to a pressure sensor placed within the airbag inflation tube, the system automatically adjusts the oxygen supply flow or triggers an alarm when the pressure approaches the upper threshold, ensuring safe and precise inflation and preventing over-inflation that could shorten the lifespan of the airbag, cause explosions, or lead to instability in the nebulizer cup.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] like Figure 1 - Figure 7 As shown, the technical solution of the present invention is as follows:

[0035] An inflatable support-type atomizing device includes a ventilation channel unit 1 and a support air cushion unit 4 connected together; the ventilation channel unit 1 includes a connected air source connecting pipe 11, an expansion pipe 12, and an airbag inflation pipe 13 and an atomizing channel 14 extending from the expansion pipe 12 respectively; the airbag inflation pipe 13 is connected to the support air cushion unit 4, and the atomizing channel 14 is connected to the atomizing cup 8.

[0036] The supporting air cushion unit 4 includes a supporting air cushion 41 located at the top and a base 42 located at the bottom. The supporting air cushion 41 is provided with an atomizing cup placement hole 413 for placing the atomizing cup 8.

[0037] It also includes a controller 6, which is connected to a pressure sensor 5 placed in the airbag inflation tube 13, so that when the pressure sensor 5 reaches a preset value, the controller 6 controls the air pressure in the airbag inflation tube 13 to continue to increase.

[0038] The first preferred embodiment disclosed in this invention, such as Figures 1-6 As shown:

[0039] An inflatable support-type atomizing device includes a connected air passage unit 1 and a support air cushion unit 4.

[0040] The ventilation unit 1 includes a connected air source connection pipe 11, an expansion pipe 12, and an airbag inflation pipe 13 and an atomizing channel 14 extending from the expansion pipe 12 respectively; an air inlet switch 111 is installed on the air source connection pipe 11, and the controller 6 is connected to the air inlet switch 111 to realize the connection and disconnection of the air source connection pipe 11 and the oxygen source.

[0041] The airbag inflation pipe 13 is connected to the supporting air cushion unit 4 through the inflation pipe interface 412, and the atomizing channel 14 is connected to the vent (not shown in the figure) in the center of the bottom wall of the atomizing cup 8.

[0042] The expansion-type pipe 12 is divided into a first chamber 122 and a second chamber 123 by a partition wall 121.

[0043] The partition 121 is located on the vertical center plane of the expansion pipe 12, and extends upward from the bottom wall to form a semi-circular partition 121. The first chamber 122 and the second chamber 123 are respectively connected to the airbag inflation pipe 13 and the atomizing channel 14. Under the separation of the partition 121, the gas in the first chamber 122 and the second chamber 123 automatically flows to the airbag inflation pipe 13 and the atomizing channel 14, respectively, and the gas flow is smoother.

[0044] The diameters of the air source connecting pipe 11, the airbag inflation pipe 13, and the atomizing channel 14 are all d. The diameter D of the expansion pipe 12 should satisfy: D≥4d; d is 2~3mm, D is 8~12mm. In this embodiment, d=3mm, D=12mm. This parallel structure ensures rapid and uniform inflation, and supports the air cushion 41 to expand to the predetermined shape synchronously, providing a balanced and stable support force field for the atomizing cup 8 and avoiding the risk of the atomizing cup tilting due to uneven local pressure.

[0045] The airbag inflation pipe 13 and the atomizing channel 14 are respectively equipped with a first switch 2 and a second switch 3 for controlling air intake, which can be manually opened or closed as needed to control the entry or stop of oxygen into the support air cushion unit 4 or the atomizing cup.

[0046] A pressure sensor 5 is installed on the wall of the airbag inflation pipe 13. The pressure sensor 5 is communicatively connected to an external controller 6. The controller 6 is connected to an air inlet switch 111 at the air inlet end of the air source connection pipe 11. When the pressure sensor 5 reaches a preset value, a signal is sent to the controller 6, and the controller 6 controls the air inlet switch 111 to close. The pressure sensor 5 has a range of 0-50 kPa and an accuracy of ±0.5 kPa.

[0047] The air source connection pipe 11, the expansion pipe 12, the airbag inflation pipe 13, and the atomization channel 14 are all made of high-strength medical-grade silicone, which has excellent elastic deformation capability and fatigue resistance. It can withstand thousands of inflation and deflation cycles with stable performance. The silicone Shore hardness range is precisely controlled between 30 and 40 HA, ensuring that it can provide solid support while having a moderate softness to fit the human body after inflation.

[0048] The supporting air cushion unit 4 includes a supporting air cushion 41 at the top and a base 42 at the bottom. The base 42 is fitted over the bottom of the supporting air cushion 41. The supporting air cushion unit 4 has a cavity 417 inside. When the cavity 417 is filled with gas, the bottom of the supporting air cushion 41 expands in the groove 421 of the base 42, so that the bottom of the supporting air cushion 41 is fixed in the base 42.

[0049] The supporting air cushion 41 includes a right-angled trapezoidal part 414 at the upper end and a square part 415 at the lower end. The right-angled trapezoidal part 414 and the square part 415 are an integral structure. The cavity 417 inside is connected to the airbag inflation pipe 13 through the inflation pipe interface 412.

[0050] The right-angled trapezoidal portion 414 has a vertical atomizing cup placement hole 413 on its inclined surface 4141 for placing the atomizing cup 8. The atomizing cup 8 is in an upright state. The square portion 415 has a recess 411 on its upper edge and in the middle. The vertical center plane of the atomizing cup placement hole 413 located at the bottom point of the inclined surface 4141 also passes through the vertical center plane of the recess 411, so that when the patient places his / her chin on the recess 411, the atomizing mask 82 covers the patient's face.

[0051] The right-angled trapezoidal portion 414 is also provided with an inner groove 416 for placing the atomizing channel 14. The inner groove 416 is connected to the edge of the atomizing cup placement hole 413, so that after the atomizing channel 14 is placed in the inner groove 416 and tightly engaged with the bottom of the cup body 81 of the atomizing cup 8, both the atomizing cup 8 and the atomizing channel 14 are in a stable state.

[0052] The supporting air cushion 41 has a multi-layer nested structure, comprising, from the outside to the inside, a protective layer 4181 made of wear-resistant and weather-resistant polyester fiber composite material, a supporting layer 4182 made of high-strength polyamide fiber woven to provide the air cushion with support strength and shape retention, and an airtight layer 4183 made of high-barrier butyl rubber to ensure zero gas leakage; the thickness of the protective layer 4181 is set to 1-2 mm, and 2 mm in this embodiment; the thickness of the supporting layer is set to 3-5 mm, and 4 mm in this embodiment; the thickness of the airtight layer 4183 is set to 0.5-1 mm, and 1 mm in this embodiment.

[0053] The base 42 includes a seat body surrounded by a bottom wall 423, a side wall 424, and a top wall 422. The seat body has an inner cavity, and the top wall has an upper opening 4221. The upper opening 4221 is square and matches the square part 415. When the square part 415 of the supporting air cushion 41 is inserted into the inner cavity and filled with gas, the square part expands and is fixed in the groove 421 on the inner edge of the seat body. In addition, the base 42 is made of hard plastic to achieve a preset weight so that the supporting air cushion 41 is placed flat and stable, ensuring that the atomizing cup 8 is always in a horizontal and stable state.

[0054] The second preferred embodiment disclosed in this invention, such as Figures 2-7 As shown:

The first chamber 122 and the second chamber 123 are respectively connected to the airbag inflation pipe 13 and the atomizing channel 14. Under the separation of the partition 121, the gas in the first chamber 122 and the second chamber 123 automatically flows to the airbag inflation pipe 13 and the atomizing channel 14, respectively, and the gas flow is smoother.

[0060] The diameters of the air source connecting pipe 11, the airbag inflation pipe 13, and the atomizing channel 14 are all d. The diameter D of the expansion pipe 12 should satisfy: D≥4d; d is 2~3mm, D is 8~12mm. In this embodiment, d=2mm, D=8mm. This parallel structure ensures rapid and uniform inflation, and supports the air cushion 41 to expand to the predetermined shape synchronously, providing a balanced and stable support force field for the atomizing cup 8 and avoiding the risk of the atomizing cup tilting due to uneven local pressure.

[0061] The airbag inflation pipe 13 and the atomizing channel 14 are respectively equipped with a first switch 2 and a second switch 3 for controlling air intake, which can be manually opened or closed as needed to control the entry or stop of oxygen into the support air cushion unit 4 or the atomizing cup 8.

[0062] A pressure sensor 5 is installed on the wall of the airbag inflation pipe 13. The pressure sensor 5 is communicatively connected to an external controller 6. The controller 6 is connected to an alarm 7, so that when the pressure sensor 5 reaches a preset value, a signal is sent to the controller 6, and the controller 6 controls the alarm 7 to sound an alarm. The alarm can be manually turned off in time. The pressure sensor 5 has a range of 0-50 kPa and an accuracy of ±0.5 kPa.

[0063] The air source connection pipe 11, the expansion pipe 12, the airbag inflation pipe 13, and the atomization channel 14 are all made of high-strength medical-grade silicone, which has excellent elastic deformation capability and fatigue resistance. It can withstand thousands of inflation and deflation cycles with stable performance. The silicone Shore hardness range is precisely controlled between 30 and 40 HA, ensuring that it can provide solid support while having a moderate softness to fit the human body after inflation.

[0064] The supporting air cushion unit 4 includes a supporting air cushion 41 at the top and a base 42 at the bottom. The base 42 is fitted over the bottom of the supporting air cushion 41. The supporting air cushion unit 4 has a cavity 417 inside. When the cavity 417 is filled with gas, the bottom of the supporting air cushion 41 expands in the groove 421 of the base 42, so that the bottom of the supporting air cushion 41 is fixed in the base 42.

[0065] The supporting air cushion 41 includes a right-angled trapezoidal part 414 at the upper end and a square part 415 at the lower end. The right-angled trapezoidal part 414 and the square part 415 are an integral structure. The cavity 417 inside is connected to the airbag inflation pipe 13 through the inflation pipe interface 412.

[0066] The right-angled trapezoidal portion 414 has a vertical atomizing cup placement hole 413 on its inclined surface 4141 for placing the atomizing cup 8. The atomizing cup 8 is in an upright state. The square portion 415 has a recess 411 on its upper edge and in the middle. The vertical center plane of the atomizing cup placement hole 413 located at the bottom point of the inclined surface 4141 also passes through the vertical center plane of the recess 411, so that when the patient places his / her chin on the recess 411, the atomizing mask 82 covers the patient's face.

[0067] The right-angled trapezoidal portion 414 is also provided with an inner groove 416 for placing the atomizing channel 14. The inner groove 416 is connected to the edge of the atomizing cup placement hole 413, so that after the atomizing channel 14 is placed in the inner groove 416 and tightly engaged with the bottom of the cup body 81 of the atomizing cup 8, both the atomizing cup 8 and the atomizing channel 14 are in a stable state.

[0068] The supporting air cushion 41 has a multi-layer nested structure, comprising, from the outside to the inside, a protective layer 4181 made of wear-resistant and weather-resistant polyester fiber composite material, a supporting layer 4182 made of high-strength polyamide fiber woven to provide the air cushion with support strength and shape retention, and an airtight layer 4183 made of high-barrier butyl rubber to ensure zero gas leakage; the thickness of the protective layer 4181 is set to 1-2 mm, and 1 mm is used in this embodiment; the thickness of the supporting layer is set to 3-5 mm, and 3 mm is used in this embodiment; the thickness of the airtight layer 4183 is set to 0.5-1 mm, and 0.5 mm is used in this embodiment.
