Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nebulization auxiliary device for critically ill medical patients. Background Technology

[0002] Oxygen-driven nebulization (high-speed airflow-driven nebulization) uses high-speed airflow to create negative pressure at the outlet, drawing the medication out through a small tube. The drawn-out medication is then impacted by the high-speed airflow at the outlet, breaking it into fine droplets. These small droplets are easily absorbed by the mucous membranes. Nebulized inhalation therapy acts directly on the affected area, resulting in rapid effectiveness and few side effects.

[0003] Chinese Patent Publication No. CN203954364U discloses a disposable nebulizer, including a nebulizer mouthpiece, a three-way connector connected to the left end of the nebulizer mouthpiece, an exhalation tube connected to the right end of the three-way connector, a medicine bottle connected to the lower end of the three-way connector, a nebulizer core disposed in the medicine bottle, and a liquid jet tube disposed at the upper end of the medicine bottle; a one-way piston is provided at the liquid outlet position of the medicine bottle, which opens when inhaling and closes when exhaling, and a device for monitoring the amount of inhaled drug-containing gas is provided on the one-way piston.

[0004] However, when using the above-mentioned device, the patient needs to sit upright to ensure that the medicine cup is perpendicular to the ground, thus avoiding any residue of the medicine inside the cup. But when the patient's physical condition does not allow this, the patient's body cannot sit upright. Therefore, when using the nebulizer in this case, the medicine bottle is tilted and cannot be kept perpendicular to the ground. The medicine inside the medicine cup will accumulate at the bottom of the medicine cup and cannot be completely atomized. Therefore, medicine residue will be generated when using the nebulizer in this case. In addition, when cleaning the above-mentioned device after use, the liquid jet tube is easy to fall out of the nebulizer. Once the liquid jet tube falls out of the nebulizer, the nebulizer can no longer be used. Therefore, a new nebulizer needs to be replaced. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art, such as the residual medicine inside the medicine cup when the medicine cup is tilted, and the easy for the liquid jet tube to fall out of the nebulizer, thus requiring the replacement of a new nebulizer.

[0006] A nebulization auxiliary device for critically ill medical patients is proposed, comprising a nebulizer assembly, a rotating assembly, a three-way connecting tube, and a drying assembly. The nebulizer assembly is located below the rotating assembly, and the lower end of the rotating assembly is connected to the interior of the nebulizer assembly. The three-way connecting tube is located above the rotating assembly and is connected to the rotating assembly. The drying assembly is located below the nebulizer assembly, and the nebulizer assembly is snapped onto the drying assembly.

[0007] In this invention, after connecting the rotating assembly and the nebulizer assembly, the position of the nebulizer assembly can be adjusted according to the patient's condition. To rotate the nebulizer assembly clockwise or counterclockwise, press the lever at the bottom of the rotating cylinder, then rotate the housing, the fixed cylinder, and the nebulizer assembly. After rotating the nebulizer assembly to the desired position, release the lever at the bottom of the rotating cylinder. To swing the nebulizer assembly left or right, press the lever at the top of the fixed cylinder, then swing the nebulizer assembly. After swinging the nebulizer assembly to the desired position, release the lever. The pressure rod at the top of the fixed cylinder is opened to ensure that the liquid cup is perpendicular to the ground, thus preventing liquid residue from forming inside the liquid cup. When the liquid jet tube is placed inside the liquid cup, the first locking block can be inserted into the pre-set through hole on the connecting cylinder to connect the liquid jet tube to the liquid cup through the locking method, thereby preventing the liquid jet tube from falling out of the liquid cup. This solves the problem mentioned in the technical background that when the liquid cup is tilted, liquid residue will form inside the liquid cup and the liquid jet tube is easy to fall out of the atomizer, thus requiring the replacement of a new atomizer.

[0008] In a preferred embodiment of the present invention, the rotating assembly includes a housing, a bellows, a rotating cylinder, a fixed cylinder, a pressure rod, a spring, and a guide cylinder. Four guide cylinders are connected to the four side plates of the housing. The rotating cylinder and the fixed cylinder are respectively positioned above and below the housing, with the lower end of the rotating cylinder and the upper end of the fixed cylinder hinged to the guide cylinders. A pressure rod is slidably connected inside each set of guide cylinders, and a spring is provided at one end of each pressure rod. The two ends of the spring are connected to the pressure rod and the guide cylinder, respectively. The bellows is located inside the housing, with both ends connected to the rotating cylinder and the fixed cylinder, respectively. When the patient performs nebulization, the position of the nebulizer assembly can be adjusted via the rotating assembly to ensure that the medication cup is perpendicular to the ground, thereby preventing medication residue from forming inside the medication cup.

[0009] In a preferred embodiment of the present invention, the outer wall of the fixing cylinder is provided with a plurality of slots for connecting with the drying assembly. After the fixing cylinder is inserted into the fixing block of the drying assembly, the protrusion on the inner wall of the fixing block can be engaged in the slots, thereby restricting the position of the fixing cylinder and preventing the rotating assembly from falling off the drying assembly.

[0010] In a preferred embodiment of the present invention, the atomizer assembly includes a bottle cap, a medicine cup, a speed reducer, a liquid jet tube, a connecting cylinder, a first locking block, a sealing ring, and an air tube. The medicine cup is located at the lower end of the bottle cap and is connected to the bottle cap. The speed reducer is horizontally bonded to the inside of the medicine cup. The air tube is connected to the center of the speed reducer. The liquid jet tube is located above the speed reducer and is connected to the air tube. The connecting cylinder is connected to the lower part of the liquid jet tube. There are multiple first locking blocks, all of which are connected to the speed reducer and are connected to the connecting cylinder. The sealing ring is located above the connecting cylinder and is connected to the liquid jet tube. By connecting the connecting cylinder and the first locking blocks together by a locking mechanism, the liquid jet tube can be prevented from falling out of the medicine cup when cleaning the medicine cup.

[0011] In a preferred embodiment of the present invention, the inner wall at the lower end of the medicine cup is provided with a thread for connection with the drying assembly. After the medicine cup is cleaned, it can be connected to the tray by the threaded connection, thereby preventing the medicine cup from falling off the tray during drying.

[0012] In a preferred embodiment of the present invention, the drying assembly includes a tray, a fixing block, a second locking block, a first threaded cylinder, and a second threaded cylinder. Multiple fixing blocks are vertically connected to the tray. Four second locking blocks are disposed at one end of each fixing block and connected to the tray. The first and second threaded cylinders are parallel to each other on one side of the fixing block and vertically connected to the tray. The fixing block is made of plastic with elastic deformation capability, so that when the fixing cylinder is inserted downwards into the fixing block, the top of the fixing block pops outwards until the protrusion on the inner wall of the fixing block inserts into the slot on the outer wall of the fixing cylinder, thus preventing the fixing cylinder from falling out of the fixing block during drying.

[0013] In a preferred embodiment of the present invention, the tray has multiple sets of through holes. After the atomizer assembly and the rotating assembly are cleaned and connected to the tray, water droplets on the atomizer assembly and the rotating assembly can drip off the tray through the through holes, thereby preventing water droplets from accumulating inside the atomizer assembly and the rotating assembly.

[0014] In a preferred embodiment of the present invention, a clip is connected to the bottom of the tray. After the cleaned nebulizer assembly and rotating assembly are connected to the tray, the tray can be clamped and fixed to the patient's bed by the clip, thereby ensuring that the nebulizer assembly and rotating assembly can be retrieved immediately during use.

[0015] In a preferred embodiment of the present invention, a mouthpiece is connected to the three-way connecting tube, allowing the patient to inhale the atomized medication by biting down on the mouthpiece, thereby reducing medication waste.

[0016] The advantages of this utility model compared with the prior art are: This invention allows the position of the nebulizer assembly to be adjusted by rotating the component during nebulization, ensuring that the medication cup of the nebulizer assembly remains perpendicular to the ground. This prevents medication residue from forming inside the medication cup during nebulization. Furthermore, when connecting the liquid jet tube to the medication cup, the first locking block and connecting cylinder are used to connect the liquid jet tube and the medication cup together by a locking mechanism, thus preventing the liquid jet tube from falling out of the medication cup when cleaning it.

Detailed Implementation

[0018] The following will refer to the appendix in the embodiments of this utility model. Figure 1-14 The technical solutions in the embodiments of this utility model will be described in detail below.

[0019] like Figure 1-3 As shown, a medical nebulization auxiliary device for critically ill patients includes a nebulizer assembly 1, a rotating assembly 2, a three-way connecting pipe 3, and a drying assembly 4. The nebulizer assembly 1 is vertically arranged below the rotating assembly 2, and the lower end of the rotating assembly 2 is inserted into the interior of the top of the nebulizer assembly 1.

[0020] like Figure 1-3 As shown, when a patient is taking nebulized inhalation, the medication is simply placed inside the nebulizer assembly 1, and then after connecting the nebulizer assembly 1 and the air tube 18 together, the gas enters the interior of the nebulizer assembly 1 from the bottom air inlet.

[0021] like Figure 1-3 As shown, when the liquid is sprayed from the outlet at the top of the atomizer assembly 1, the liquid inside the atomizer assembly 1 is atomized, and then the atomized liquid enters the interior of the rotating assembly 2 from the outlet at the top of the atomizer assembly 1.

[0022] like Figure 1-3 As shown, the three-way connecting pipe 3 is located at the top of the rotating component 2, and the middle section of the three-way connecting pipe 3 is connected to the rotating component 2. Therefore, after the atomized liquid enters the interior of the rotating component 2, it can enter the interior of the three-way connecting pipe 3 again through the air outlet at the top of the rotating component 2.

[0023] like Figure 1-3 As shown, one end of the three-way connecting tube 3 is connected to the outside air, and the other end of the three-way connecting tube 3 can be connected to a mouthpiece 31. Therefore, when the patient bites on the mouthpiece 31 and breathes, the air inside the ventilator can bring the nebulized medicine inside the three-way connecting tube 3 into the patient's body along with the air inside the ventilator.

[0024] like Figure 1-3As shown, the drying assembly 4 is located below the atomizer assembly 1, and the atomizer assembly 1 is snapped onto the drying assembly 4. After the atomizer assembly 1 and the rotating assembly 2 have been used, the atomizer assembly 1 and the rotating assembly 2 can be disassembled and cleaned. Then, the disassembled atomizer assembly 1 and the rotating assembly 2 can be snapped onto the drying assembly 4 for drying.

[0025] like Figure 4-7 As shown, the rotating assembly 2 includes a housing 21, a bellows 22, a rotating cylinder 23, a fixed cylinder 24, a pressure rod 25, a spring 26, and a guide cylinder 27. There are four guide cylinders 27, which are respectively arranged around the housing 21, and one end of each of the four guide cylinders 27 is bonded to the outer surface of the housing 21.

[0026] like Figure 4-7 As shown, the rotating cylinder 23 and the fixed cylinder 24 are respectively located above and below the housing 21, and the lower end of the rotating cylinder 23 and the top end of the fixed cylinder 24 are rotatably connected to the guide cylinder 27. Each guide cylinder 27 is provided with a set of pressure rods 25 and springs 26 inside.

[0027] like Figure 4-7 As shown, one end of the pressure rod 25 is slidably disposed inside the guide cylinder 27, and the other end of the pressure rod 25 passes through the guide cylinder 27 and is disposed outside the rotating cylinder 23 and the fixed cylinder 24. The spring 26 is located at one end of the pressure rod 25 and is disposed laterally inside the guide cylinder 27, and the two ends of the spring 26 are respectively connected to the pressure rod 25 and the guide cylinder 27.

[0028] like Figure 4-7 As shown, when the pressure rod 25 is pressed, the pressure rod 25 will compress the spring 26 as it moves into the guide cylinder 27. At this time, the spring 26 will undergo elastic deformation and store force, so when the pressure rod 25 is released, the spring 26 will push the pressure rod 25 out.

[0029] like Figure 4-7 As shown, the pressure rod 25 has multiple protrusions on one end of the guide cylinder 27, and the protrusions pass through the guide cylinder 27 and are located on the outside of the guide cylinder 27. Multiple grooves are opened on the inner walls of the rotating cylinder 23 and the fixed cylinder 24 at the position of the guide cylinder 27.

[0030] like Figure 4-7 As shown, when the pressure rod 25 moves inward, it will move the protrusion out of the groove on the inner wall of the rotating cylinder 23 and the fixed cylinder 24, at which time the rotating cylinder 23 and the fixed cylinder 24 can rotate, and when the pressure rod 25 is ejected outward by the spring 26.

[0031] like Figure 4-7As shown, once the protrusion on the pressure rod 25 is ejected into the groove on the inner wall of the rotating cylinder 23 and the fixed cylinder 24, the rotating cylinder 23 and the fixed cylinder 24 will be stuck by the pressure rod 25, and thus the rotating cylinder 23 and the fixed cylinder 24 will no longer be able to rotate.

[0032] like Figure 4-7 As shown, the bellows 22 is vertically arranged inside the housing 21. The upper end of the bellows 22 is inserted into the rotating cylinder 23, and the lower end of the bellows 22 is inserted into the fixed cylinder 24. The middle section of the three-way connecting pipe 3 is inserted into the interior of the rotating cylinder 23.

[0033] like Figure 4-7 As shown, the lower end of the fixed cylinder 24 is inserted into the interior of the atomizer assembly 1. Therefore, after the atomized liquid is discharged into the interior of the fixed cylinder 24 by the atomizer assembly 1, it can enter the interior of the rotating cylinder 23 through the corrugated tube 22, and then enter the interior of the three-way connecting tube 3 through the rotating cylinder 23 to wait for inhalation.

[0034] like Figure 4-7 As shown, a slot 5 is provided on the outer wall of the fixing cylinder 24. The fixing cylinder 24 is connected to the drying assembly 4 through the slot 5, thus preventing it from falling off the drying assembly 4 when the rotating assembly 2 is used for drying.

[0035] like Figure 8-11 As shown, the atomizer assembly 1 includes a bottle cap 11, a medicine cup 12, a speed reducer 13, a liquid jet tube 14, a connecting tube 15, a first locking block 16, a sealing ring 17, and an air tube 18. The middle section of the three-way connecting tube 3 is inserted into the inside of the bottle cap 11 from the top.

[0036] like Figure 8-11 As shown, the liquid medicine cup 12 is located at the lower end of the bottle cap 11, and the liquid medicine cup 12 is connected to the bottle cap 11 through a pre-set thread at the lower end of the bottle cap 11, so as to prevent the liquid medicine from leaking out from the gap between the liquid medicine cup 12 and the bottle cap 11 when atomizing. The inner wall at the lower end of the liquid medicine cup 12 is also provided with threads.

[0037] like Figure 8-11 As shown, after the medicine cup 12 is cleaned, the medicine cup 12 can be connected to the drying assembly 4 through the thread at the lower end of the medicine cup 12. The medicine cup 12 has a speed reduction plate 13 arranged horizontally inside, and the speed reduction plate 13 is attached to the inner wall of the medicine cup 12.

[0038] like Figure 8-11As shown, the air pipe 18 is connected to the center of the deceleration plate 13, the liquid jet pipe 14 is located inside the liquid cup 12 and is set above the deceleration plate 13, and the shape of the liquid jet pipe 14 is funnel-shaped. The connecting tube 15 is located below the liquid jet pipe 14 and is attached to the liquid jet pipe 14 (the connecting tube 15 is made of plastic with elastic deformation capability).

[0039] like Figure 8-11 As shown, the connecting cylinder 15 has a slot corresponding to the first locking block 16. The liquid jet pipe 14 and the connecting cylinder 15 are inserted into the air pipe 18. The sealing ring 17 is located on the outside of the liquid jet pipe 14 and is bonded to the liquid jet pipe 14.

[0040] like Figure 8-11 As shown, when the liquid jet tube 14 is inserted into the air tube 18 and the liquid is poured into the medicine cup 12, the liquid will remain on the liquid jet tube 14, thereby preventing the liquid from flowing down the liquid jet tube 14 from the gap between the liquid jet tube 14 and the inner wall of the medicine cup 12.

[0041] like Figure 8-11 As shown, there are four first locking blocks 16, all of which are glued to the speed reducer 13. The four first locking blocks 16 are evenly arranged around the air pipe 18 with the axis of the air pipe 18 as the center. Therefore, after the liquid jet pipe 14 and the connecting cylinder 15 are inserted into the air pipe 18, the medicine cup 12 and the liquid jet pipe 14 can be locked together through the preset through holes on the first locking blocks 16 and the connecting cylinder 15, so as to prevent the liquid jet pipe 14 from falling out of the medicine cup 12.

[0042] like Figure 8-11 As shown, the liquid jet tube 14 used is funnel-shaped. Therefore, when the airflow is ejected from the outlet at the top of the liquid jet tube 14, the air pressure at the outlet at the top of the liquid jet tube 14 will draw the liquid inside the liquid cup 12 upward.

[0043] like Figure 8-11 As shown, the liquid medicine will then impact the pre-set baffle with gaps inside the bottle cap 11. The impacted liquid medicine will form mist particles, and the mist particles will then enter the interior of the fixed cylinder 24 through the gaps in the baffle.

[0044] like Figure 12-14 As shown, the drying assembly 4 includes a tray 41, a fixing block 42, a second locking block 43, a first threaded cylinder 44, and a second threaded cylinder 45. Through holes are provided on the tray 41 at the positions of the fixing block 42, the second locking block 43, the first threaded cylinder 44, and the second threaded cylinder 45.

[0045] like Figure 12-14As shown, after the atomizer assembly 1 and the rotating assembly 2 are cleaned and connected to the tray 41, the water droplets inside the atomizer assembly 1 and the rotating assembly 2 can flow out through the through hole on the tray 41. There are four fixing blocks 42 arranged in a ring above the tray 41, and all four fixing blocks 42 are vertically bonded to the tray 41.

[0046] like Figure 12-14 As shown, all the fixing blocks 42 used are made of plastic with elastic deformation capability. Therefore, after cleaning, the rotating component 2 can be clamped onto the tray 41 by the slot 5 on the outer wall of the fixing cylinder 24 and the fixing block 42, so as to prevent the rotating component 2 from falling off the tray 41.

[0047] like Figure 12-14 As shown, there are four second locking blocks 43, all of which are located at one end of the fixing block 42. The four second locking blocks 43 are annularly bonded to the top of the tray 41. After the liquid jet pipe 14 is cleaned, the liquid jet pipe 14 can be locked onto the tray 41 through the connecting tube 15 at its bottom and the second locking blocks 43.

[0048] like Figure 12-14 As shown, this prevents the liquid jet tube 14 from falling off the support plate 41. The first threaded cylinder 44 and the second threaded cylinder 45 are arranged in parallel on one side of the fixing block 42, and both the first threaded cylinder 44 and the second threaded cylinder 45 are bonded to the support plate 41.

[0049] like Figure 12-14 As shown, after cleaning the medicine cup 12 and the bottle cap 11, the disassembled medicine cup 12 and bottle cap 11 can be connected to the first threaded cylinder 44 and the second threaded cylinder 45 respectively. A clip 6 is provided below the support plate 41.

[0050] like Figure 12-14 As shown, the clip 6 is connected to the lower surface of the tray 41 by screws. After the rotating assembly 2 and the nebulizer assembly 1 are connected to the tray 41, the clip 6 can be used to clamp and fix the tray 41 to the patient's bed.

[0051] The movement process in this embodiment is as follows: After the liquid jet pipe 14 is snapped onto the deceleration plate 13, the liquid medicine can be put into the inside of the liquid medicine cup 12. Then, the liquid medicine cup 12 can be threaded onto the bottle cap 11, and the lower end of the fixing cylinder 24 can be inserted into the inside of the bottle cap 11. Then, the middle section of the three-way connecting pipe 3 can be inserted into the inside of the rotating cylinder 23.

[0052] The nozzle 31 is inserted into the connection port at one end of the three-way connecting pipe 3. The connection port at the other end of the three-way connecting pipe 3 can be connected to the outside air. Then the atomizing tube can be connected to the air pipe 18 at the lower end of the speed reducer 13. As the gas inside the atomizing tube flows into the fixed cylinder 24 through the air pipe 18, the liquid inside the liquid cup 12 can be drawn upward through the liquid jet pipe 14 and atomized.

[0053] After atomization, the liquid medicine can enter the interior of the fixed cylinder 24. The liquid medicine inside the fixed cylinder 24 can then enter the interior of the rotating cylinder 23 through the corrugated tube 22, and then enter the interior of the three-way connecting tube 3 through the rotating cylinder 23. At this time, when the patient bites down on the mouthpiece 31 and performs an inhalation operation, the liquid medicine particles inside the three-way connecting tube 3 and the outside air can be inhaled together.

[0054] When the patient is performing inhalation, the position of the nebulizer assembly 1 can be adjusted by rotating component 2. When pressing the lever 25 at the lower end of rotating cylinder 23, the housing 21, fixed cylinder 24 and nebulizer assembly 1 can be rotated clockwise or counterclockwise. When pressing the lever 25 at the top of fixed cylinder 24, the fixed cylinder 24 and nebulizer assembly 1 can be swung left and right to adjust the position of nebulizer assembly 1, thereby ensuring that the medicine cup 12 is always perpendicular to the ground.

[0055] When using a nebulizer mask for nebulized inhalation, the patient can directly remove the three-way connector from the rotating assembly, and then insert the mask's inlet tube into the rotating cylinder. The airflow then enters the medication cup and atomizes the medication, forming atomized particles that can be directly passed through the rotating assembly into the mask and inhaled by the patient. Furthermore, when the nebulizer tube is supplying airflow into the medication cup, it can be used in conjunction with existing oxygen booster equipment to increase the airflow speed into the medication cup, thereby accelerating the nebulization efficiency.

[0056] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
