Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and more specifically, relates to a supine nebulizer. Background Art

[0002] As an important drug delivery method for respiratory diseases, aerosol inhalation therapy has been used clinically for over half a century. Traditional nebulizers are primarily designed for use in sitting or standing positions, exposing significant technical deficiencies when used with bedridden patients, particularly those in intensive care units and those recovering from surgery.

[0003] First, the existing mask structure generally adopts a design scheme of rigid sealing ring combined with elastic strap. Clinical observations have found that when the patient is in the supine or lateral position, the contact pressure between the face and the bed surface is unevenly distributed, resulting in unilateral leakage in the existing mask. Especially for thin patients or those with facial anatomical abnormalities, the leakage rate can reach more than 35%. This not only reduces the efficiency of drug delivery, but may also cause complications such as irritation of the eye mucosa. Although some improved products have tried to increase the thickness of the silicone pad, the resulting compressive edema problem limits the feasibility of long-term use; Secondly, regarding the liquid drug storage system, conventional nebulizers use an upright liquid storage structure. Mechanical testing has shown that when the device is tilted more than 15 degrees, the uneven distribution of the drug liquid causes the dispersion of the atomized particle size to increase by 42%, directly affecting the lung deposition rate. In terms of drug delivery control, current technologies mostly use continuous atomization or simple timed membrane atomization. Traditional devices have a drug waste rate as high as 60%-70%, and continuous airflow can easily trigger respiratory resistance in patients. Although trigger-type atomizers based on flow sensors have emerged in recent years, their response delay is still difficult to match that of rapid shallow breathing membrane atomizers. For patients with a respiratory rate greater than 30 breaths / minute, the effective trigger rate is less than 65%.

[0004] The combined effects of these technical bottlenecks directly lead to three major clinical pain points in supine nebulization therapy: low drug utilization (average <40%), poor treatment comfort (72% of patients report facial pressure), and low compliance (discontinuation rate of a single treatment session reaches 28%). Therefore, there is an urgent need to develop a supine nebulizer that can meet the treatment needs of patients in special body positions. Summary of the Invention

[0005] The purpose of the present invention is to provide a supine nebulizer to solve the technical problems of low drug utilization rate, poor treatment comfort and low operation compliance of the nebulizer in the prior art.

[0026] A supine position atomizer provided by the present invention will now be described.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 14As shown, a supine nebulizer includes a mask portion 100, an atomizing chamber portion 200 and a shell mounting portion 300; the end of the mask portion 100 is sealed with the end of the atomizing chamber portion 200; the other end of the atomizing chamber portion 200 is threadedly connected to the shell mounting portion 300; a bearing platform 310 and a liquid medicine holding box 320 are provided in the shell mounting portion 300, the bearing platform 310 is fixed in the shell mounting portion 300, and the liquid medicine holding box 320 is fixedly mounted on the bearing platform 310; the mask portion 100 includes a mask body 110 and a mask support body 120, the mask body 110 0 is fixedly connected to the mask support body 120, and the mask support body 120 is sealed with the atomization chamber 200; a plurality of magnetic bodies 130 are protruding from the end surface of the mask support body 120, and a plurality of magnetic bodies 130 are correspondingly provided on the end surface of the atomization chamber 200, and the end surface of the mask support body 120 and the end surface of the atomization chamber 200 are magnetically connected, and a pad body 140 is padded between the two end surfaces, and both end surfaces of the pad body 140 are provided with magnetic grooves 141 matching the magnetic bodies 130, and the pad body 140 is provided with a bending structure that can be bent and folded.

[0028] The present invention provides a supine position nebulizer. Compared with the prior art, when using the supine position nebulizer provided by the present invention, because the end surface of the mask support body 120 and the end surface of the atomizing chamber 200 are both provided with a magnetic body 130, and a cushion body 140 is provided between the end surface of the mask support body 120 and the end surface of the atomizing chamber 200, when the mask support body 120 and the atomizing chamber 200 are connected, the cushion body 140 is first placed on the atomizing chamber 200, so that the magnetic body 140 on the atomizing chamber 200 enters the magnetic suction groove. 141, and then bring the end face of the mask support body 120 close to the cushion body 140, the mask support body 120 and the atomizing chamber 200 will be automatically adsorbed together under the action of the magnetic force, and the magnetic body 130 on the mask support body 120 will also enter the magnetic suction groove 141; and by providing a bending structure on the cushion body 140, when the patient is in a supine position, the bending structure can be bent, so that the atomizing chamber 200 and the shell mounting part 300 can still remain in an upright state, ensuring that the nebulizer can still atomize in the supine state.

[0029] In some embodiments, as Figure 6 and Figure 7As shown, the bending structure includes a first folding ring 142 and a second folding ring 143 respectively provided at the upper and lower ends of the cushion body 140. The first folding ring 142 and the second folding ring 143 are made of soft rubber material, can be bent and folded, and can be restored to their original shape; the first folding ring 142 is provided with a first limiting convex ring 1421, and the second folding ring 143 is provided with a second limiting convex ring 1431. A first limiting groove 121 is provided on the circumferential surface of the mask support body 120, and a second limiting groove 240 is provided on the circumferential surface of the atomization chamber 200. The first limiting convex ring 1421 is limited in the first limiting groove 121, and the second limiting convex ring 1431 is limited in the second limiting groove 240.

[0030] It should be noted that the first folding ring 142 and the second folding ring 143 can be deformed and restored to their original shape. Figure 6 and Figure 7 As shown, the lengths of the first folding ring sleeve 142 and the second folding ring sleeve 143 can be selected according to specific circumstances to ensure that the first folding ring sleeve 142 and the second folding ring sleeve 143 can be bent and folded, so that a better atomization effect can be obtained. When the first folding ring sleeve 142 needs to be connected to the mask support body 120, it is only necessary to put the first folding ring sleeve 142 on the mask support body 120 and ensure that the first limiting protrusion 1421 enters the first limiting groove 121. When the second folding ring sleeve 143 needs to be connected to the atomization chamber 200, it is only necessary to put the second folding ring sleeve 143 on the atomization chamber 200 and ensure that the second limiting protrusion 1431 enters the second limiting groove 240. At this time, the connection is completed; In a specific embodiment, when the patient is in a standing position for atomization, the middle portions of the first folding ring 142 and the second folding ring 143 can be folded inwards, such as Figure 1 and Figure 6 As shown, when folded, the end surface of the mask support body 120 and the end surface of the atomizing chamber 200 automatically come close to each other and enter the magnetic suction groove 141 due to the magnetic attraction of the magnetic body 130; In another specific embodiment, when the patient needs to be in a supine position for atomization, the mask support body 120 and the atomization chamber 200 are pulled outwards, as shown in FIG. Figure 2 and Figure 7 As shown, the end surface of the mask support body 120 and the magnetic body 130 of the end surface of the atomizing chamber 200 are separated and separated from the magnetic suction groove 141, and the lengths of the first folding ring 142 and the second folding ring 143 can be freely selected. At this time, the first folding ring 142 and the second folding ring 143 can be bent, thereby ensuring that the atomizing chamber 200 and the housing mounting portion 120 can still remain in an upright state, ensuring that the atomizer can still atomize in the supine position; In addition, the first folding ring 142 and the second folding ring 143 can also adopt a folding structure similar to a "straw". With this type of structure, the purpose of folding and bending can also be achieved.

[0031] In some embodiments, as Figure 8 As shown, a plurality of first sleeves 1422 are provided at the end of the first folding sleeve 142, and the two ends of the first sleeve 1422 are connected to the circumferential surface of the first folding sleeve 142, and a first gap is formed between the first sleeve 1422 and the first folding sleeve 142, and a plurality of second sleeves 1432 are provided at the end of the second folding sleeve 143, and the two ends of the second sleeve 1432 are connected to the circumferential surface of the second folding sleeve 143, and a second gap is formed between the second sleeve 1432 and the second folding sleeve 143, and a limiting rope 150 is passed through the first gap, and the limiting rope 150 binds the first folding sleeve 142 to the mask support body 120, and the limiting rope 150 extends into the second gap and binds the second folding sleeve 143 to the atomization chamber 200.

[0032] It should also be noted that when someone quickly lifts up the mask part 100, the mask support body 120 on the mask part 100 may be separated from the first folding ring 142, or the second folding ring 143 may be separated from the atomizing chamber 200. In order to reduce the occurrence of this situation, a first sleeve 1422 is provided on the first folding ring 142, a second sleeve 1432 is provided on the second folding ring 143, and a limiting rope 150 is passed through the first gap. The limiting rope 150 has elastic force, so that it is tied to the first folding ring 142, the limiting rope 150 extends into the second gap and is tied to the second folding ring 143. If the mask is quickly lifted up, When the mask part 100 is opened, because the limiting rope 150 ties the first folding ring 142 to the mask support body 120, the limiting rope 150 in the first gap will be quickly tightened under the action of the gravity of the atomization chamber 200, causing the first folding ring 142 to be more tightly covered on the mask support body 120, and the limiting rope 150 in the first gap pulls the limiting rope 150 in the second gap, causing the limiting rope 150 in the second gap to be quickly tightened, causing the second folding ring 143 to be more tightly covered on the atomization chamber 200, thereby ensuring that the mask support body 120 on the mask part 100 will not be separated from the first folding ring 142 and the second folding ring 143 will not be separated from the atomization chamber 200.

[0033] In some embodiments, as Figure 4 and Figure 5 As shown, the mask body 110 is made of silicone material, and its shape can fit closely to the human face, and a number of memory metal wires 112 are embedded inside the edge of the mask body 110.

[0034] Specifically, the mask body 110 is made of silicone, with a memory wire 112 embedded within it. When worn on the face, the memory wire 112's elastic deformation and temperature response, combined with ergonomic design, achieves an adaptive fit. When in contact with the skin (approximately 33-37°C), the memory wire 112 heats up and returns to its preset shape (e.g., an arc), actively conforming to facial contours and minimizing air leakage. This significantly enhances comfort and safety while ensuring effective treatment, enabling highly efficient atomization therapy. Furthermore, the memory wire 112 is strong and requires minimal weight, replacing traditional reinforced plastic brackets. This results in a lighter mask overall (approximately 30% weight reduction), making it suitable for prolonged wear.

[0035] In some embodiments, as Figure 14 As shown, the atomizing chamber 200 includes an atomizing cover 210 and an atomizing chamber 220. The atomizing cover 210 and the atomizing chamber 220 are threadedly connected, the end of the atomizing cover 210 and the end of the mask part 100 are magnetically connected, and a waterproof and breathable membrane 230 is provided between the atomizing cover 210 and the atomizing chamber 220; a plurality of micro holes 222 for mist to pass through are provided on the bottom surface of the atomizing chamber 220, and a three-layer spiral guide plate 223 is formed inside the atomizing chamber 220.

[0036] In some embodiments, as Figure 10 and Figure 11 As shown, a first annular groove 211 and a first annular boss 221 are respectively provided inside the atomizing cover 210 and on the end surface of the atomizing cavity 220. When the atomizing cover 210 and the atomizing cavity 220 are threadedly connected, the first annular boss 221 pushes the waterproof breathable membrane 230 into the first annular groove 211 to fix the waterproof breathable membrane 230.

[0037] It should be further explained that the mask or interface of an ordinary nebulizer is prone to overflow of liquid medicine when tilted or moved, causing waste and skin irritation. The present invention provides a waterproof and breathable membrane 230 at a key position of the nebulizer. When the liquid medicine turns into mist, it can pass through this waterproof and breathable membrane 230. If the liquid medicine spills during the rotation of the nebulizer, it will be blocked by this waterproof and breathable membrane 230, effectively preventing the loss of dosage caused by leakage of the mist.

[0038] When the aerosol generated by the drug liquid reaches the atomization cavity 220, it will enter the interior of the atomization cavity 220 through several micro holes 222, and under the action of the wind blown by the micro fan 334, it will enter the atomization cover 210 along the three-layer spiral guide plate 223. By adding a spiral guide plate 223 in the atomization cavity 220, the atomization efficiency, particle uniformity and drug utilization rate can be significantly optimized.

[0039] In some embodiments, as Figure 12As shown, a conduction hole is opened at the bottom of the liquid medicine holding box 320, and a piezoelectric ceramic piece 321 is embedded in the conduction hole. The surface of the piezoelectric ceramic piece 321 is gold-plated and coated with a waterproof nano-coating to atomize the liquid medicine in the liquid medicine holding box 320.

[0040] In some embodiments, as Figure 12 、 Figure 13 and Figure 14 As shown, the shell mounting portion 300 includes an outer shell 330, a cover body 340 and a balancing assembly 350. The cover body 340 is threadedly connected to the outer shell 330. The balancing assembly 350 is detachably installed in the outer shell 330. The balancing assembly 350 is used to level the liquid medicine in the liquid medicine holding box 320.

[0041] In some embodiments, as Figure 12 、 Figure 13 and Figure 14 As shown, the balancing assembly 350 includes a support frame 351, a rotating motor 352, a micro screw 353, a screw seat 354 and a counterweight 355. The two ends of the support frame 351 have a certain deformation amount. The two ends of the support frame 351 are inserted into the socket 331 opened in the outer shell 330. The rotating motor 352 is fixedly installed on the support frame 351. The micro screw 353 is rotatably connected to the support frame 351. The screw seat 354 is threadedly connected to the micro screw 353. The screw seat 354 is fixedly connected to the counterweight 355, and the counterweight 355 is located in the liquid medicine holding box 320. When the rotating motor 352 is started, its output end drives the rotation of the micro screw 353, and the micro screw 353 rotates, thereby driving the movement of the screw seat 354, and finally driving the movement of the counterweight 355.

[0042] In some embodiments, as Figure 14 As shown, the mask body 110 is embedded with a high-sensitivity microphone assembly 111 for detecting the user's breathing sound, a plurality of air holes 311 are opened on the supporting platform 310, and a battery 332, a control panel 333, a micro fan 334 and a gyroscope 335 are fixedly installed at the bottom of the outer shell 330.

[0043] Specifically, the outer shell 330 and the liquid medicine container 320 are both made of transparent materials, so the liquid medicine in the liquid medicine container 320 can be clearly seen. When the patient is in a supine position, the shell mounting portion 300 may also rotate at a small angle, so that the liquid medicine in the liquid medicine container 320 may also tilt at a small angle, causing the liquid level to shift relative to the position of the piezoelectric ceramic plate 321. If the liquid level in some areas is too high relative to the piezoelectric ceramic plate 321, high-frequency vibration will be hindered, the atomization efficiency will be reduced, and even large droplets will be generated. If the liquid level is too low relative to the piezoelectric ceramic plate 321, local dry burning will occur. At the same time, the gyroscope 335 can detect the current rotation angle of the nebulizer. The movement distance of the counterweight 355 is different for different rotation angles. The initial amount of liquid medicine in the liquid medicine holding tank 320 is certain. In order to avoid the liquid level being too high or too low, when nebulization treatment is required, the nebulizer is held forward with the hand. When the gyroscope 335 detects that the nebulizer is rotating and its liquid level needs to be adjusted, the rotary motor 352 is started according to the preset program, driving the counterweight 355 to move in the liquid medicine holding tank 320. The liquid level of the liquid medicine is adjusted by controlling the position of the counterweight 355 in the liquid medicine. In addition, if the position of the counterweight 355 is not the optimal position, the button on the outer shell 330 can be manually pressed to control the rotary motor 352, thereby controlling the counterweight 355 to reach the optimal position, thereby ensuring the atomization effect of the nebulizer in the tilted state and the safety of the equipment.

[0044] The present invention has two working modes, one is an automatic working mode, that is, the nebulizer continuously generates atomization of the liquid medicine, and the other is a "breathing" mode, that is, the high-sensitivity microphone assembly 111 of the present invention can monitor the user's breathing sound in real time and determine whether it is an exhalation sound or an inhalation sound. When it is determined that the current sound is an exhalation sound, the nebulizer stops working, and when it is determined that the current sound is an inhalation sound, the nebulizer starts working, thereby avoiding the waste of a certain amount of liquid medicine atomization.
