Description

Technical Field

[0001] The present invention relates to the technical field of otology ear drop administration, in particular to an otology administration device. Background Art

[0002] Ear conditions such as cerumen impaction, otitis media, and otitis externa require medication administered through the external or internal auditory canal to achieve treatment. Mastering the correct eardrop technique can shorten the duration of illness and reduce the likelihood of adverse reactions. When administering medication, nurses should avoid placing the drops directly on the patient's eardrum; instead, they should allow the drops to slide down the ear wall. To avoid contamination, the bottle cap should be kept away from the external auditory canal. Furthermore, before administering medication, the drops should be warmed with warm water or by hand to prevent adverse reactions such as dizziness and nausea caused by the cold liquid.

[0003] Warming the medication manually not only occupies the nurse's hands, making it difficult for them to perform other preparations, but also reduces the efficiency of warming, especially when the number of patients receiving ear drops is high. Using water for heating requires careful control of the water temperature: it should not be too high to affect the efficacy of the medication, nor too low to affect the heating rate. Especially in winter, warm water cools quickly, making hot water inefficient for heating the medication. Furthermore, when inserting the medication into the patient's ear, the nurse must hold the patient's auricle with one hand while holding the medicine bottle with the other to drip the medication into the ear. Because some patients have small auricles, in this scenario, the nurse's hands and the medicine bottle partially obstruct the nurse's field of vision, resulting in a narrow field of view for the nurse, forcing the nurse to get closer to the patient's ear to accurately drip the medication according to the protocol.

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0036] See attached Figure 1 To the attached Figure 12 , an ear drug delivery device, see attached Figure 1 and attached Figure 2 The invention comprises a thermos cup 2 and an isolation cup 3 suspended within the thermos cup 2. An air cavity 4 is defined between the isolation cup 3 and the thermos cup 2. An annular connecting plate 5 is provided between the top of the isolation cup 3 and the top of the thermos cup 2. The connecting plate 5 is bonded to both the isolation cup 3 and the thermos cup 2. A hot air assembly is provided within the air cavity 4. Evenly distributed air inlet holes 6 are provided at the top of the side wall of the isolation cup 3. The air inlet holes 6 connect the air cavity 4 with the interior of the isolation cup 3.

[0037] See attached for details Figure 2 , Attachment Figure 3 and attached Figure 4The hot air assembly of this embodiment includes a rotating motor 20 disposed at the bottom of the air cavity 4. The rotating motor 20 is bonded to the bottom surface of the thermos cup 2. A rotating rod 21 connected to the output shaft of the rotating motor 20 is provided at the top of the rotating motor 20. A round block 22 bonded to the rotating rod 21 is provided at the top of the rotating rod 21. Fan blades 23 are provided on the side walls of the round block 22. The round block 22 and the fan blades 23 are integrally manufactured.

[0038] The hot air component also includes a heating wire 24 arranged around the thermos cup 2 and the isolation cup 3. The height of the heating wire 24 is higher than the height of the fan blades 23. The heating wire 24 is located at the bottom end of the isolation cup 3. The heating temperature of the heating wire 24 is about 37°C. The bottom end of the outer wall of the thermos cup 2 is provided with a ventilation hole 25 to facilitate the fan blades 23 to blow air. The rotating motor 20 drives the rotating rod 21 to rotate, and the rotating rod 21 drives the fan blades 23 to rotate. The fan blades 23 blow air toward the isolation cup 3 located above the fan blades 23. The wind becomes hot air after passing through the heating wire 24. The hot air enters the isolation cup 3 through the air inlet 6 from the air cavity 4, thereby continuously heating the medicine bottle 1 in the isolation cup 3. The bottom surface of the isolation cup 3 is a spherical surface that is convex toward the side where the fan blades 23 are located, so that the wind can spread toward both sides of the isolation cup 3.

[0039] See attached for details Figure 4 and attached Figure 9 The bottom surface of the isolation cup 3 is provided with a support component that can be extended and retracted along the height direction of the isolation cup 3. The top of the support component is provided with a suction cup 8 made of heat-insulating material that can suck the medicine bottle 1. A spring 9 is provided in the center of the top surface of the suction cup 8. A support sheet 10 is provided on the top of the spring 9. The support sheet 10 is bonded to the spring 9. A temperature sensor chip 11 is provided on the top of the support sheet 10.

[0040] A control screen 7 is provided on the outer wall of the thermos cup 2. The control screen 7 is used to control the turning on and off of the rotating motor 20 and the heating wire 24, and at the same time monitor the temperature inside the isolation cup 3 detected by the temperature sensor chip 11. When the temperature is high, the control screen 7 can control the rotating motor 20 and the heating wire 24 to be turned off. When the temperature becomes low, the rotating motor 20 and the heating wire 24 are controlled to be turned on.

[0041] See attached Figure 10The support assembly of this embodiment includes two fixed rods 26. The bottom of the fixed rods 26 is bonded to the bottom surface of the isolation cup 3. The top of the fixed rods 26 is provided with a movable cavity 27 arranged along the height direction of the fixed rods 26. A movable rod 28 is provided in the movable cavity 27, the top of which passes through the movable cavity 27. The movable rod 28 can move in the movable cavity 27 along the height direction of the fixed rods 26. The top of the movable rod 28 is bonded to the bottom of the suction cup 8. The inner wall of the movable cavity 27 is provided with an annular groove 29 arranged along the annular direction of the movable cavity 27. The top of the annular groove 29 does not pass through the top of the fixed rods 26. The outer wall of the bottom end of the movable rod 28 is provided with an annular slider 30 located in the annular groove 29 and can slide along the height direction of the annular groove 29. The annular slider 30 is bonded to the movable rod 28. The bottom and top surfaces of the annular groove 29 are both provided with buffer pads 31. The buffer pads 31 can reduce noise.

[0042] A rocking assembly is provided between the bottom of the suction cup 8 and the bottom surface of the isolation cup 3, which can propel the suction cup 8 along the height direction of the isolation cup 3. The rocking assembly of this embodiment includes a vertically disposed support rod 32 that passes through the bottom of the isolation cup 3 and is bonded to the top of the round block 22. A vertically disposed inverted trapezoidal plate 33 is provided on the top of the support rod 32. Both ends of the top of the trapezoidal plate 33 are provided with spherical protrusions 34, which are bonded to the trapezoidal plate 33. Support blocks 35 are provided on the sides of the two movable rods 28 facing each other. Support blocks 35 are bonded to the movable rods 28. A spherical protrusion 36 is provided on the bottom of the support block 35, which is bonded to the support block 35.

[0043] The rotating motor 20 drives the circular block 22 to rotate. As the circular block 22 drives the trapezoidal plate 33, it simultaneously rotates the two protrusions 1 34 to the sides of the two protrusions 2 36. As the trapezoidal block continues to rotate, the two protrusions 1 34 lift and then lower the two protrusions 2 36. During this process, the movable rod 28 moves upward or downward relative to the fixed rod 26, thereby lifting or lowering the movable rod 28 and the suction cup 8. Therefore, as the circular block 22 continues to rotate, the protrusion 1 34 continuously lifts or lowers the medicine bottle 1, thereby shaking the liquid medicine in the medicine bottle 1. To reduce the noise caused by the collision between the protrusions 1 34 and 2 36, a layer of soft rubber can be attached to the surfaces of the protrusions 1 34 and 2 36 to achieve the purpose of noise reduction.

[0044] The height of the annular groove 29 is sufficient for protrusion 1 34 to completely lift up protrusion 2 36. At the same time, if the device is placed upside down, the movable rod 28 will slide with the annular slider 30 to the end of the annular groove 29 close to the suction cup 8 due to the action of gravity. At this time, if the round block 22 drives the trapezoidal plate 33 to rotate, protrusion 1 34 can no longer touch protrusion 2 36. Therefore, when the nurse drips medicine for the patient, when the rotating motor 20 continues to run, the trapezoidal block no longer shakes the medicine bottle 1, thereby ensuring stable operation of the nurse.

[0045] See attached for details Figure 3 , Attachment Figure 4 and attached Figure 5 In this embodiment, a groove 37 is provided on the top surface of the suction cup 8, and a soft rubber ring 38 is provided on the top surface of the suction cup 8 around the groove 37. The soft rubber ring 38 is bonded to the suction cup 8 and can be tightly attached to the bottom of the medicine bottle 1. The bottom of the spring 9 is bonded to the center of the groove 37. When the spring 9 is in a completely relaxed state, the spring 9 pushes the temperature sensor chip 11 out of the groove 37, so that after the medicine bottle 1 is installed, the medicine bottle 1 squeezes the spring 9, so that the temperature sensor chip 11 can fit with the bottom surface of the medicine bottle 1.

[0046] The outer wall of the suction cup 8 is provided with a horizontally arranged channel 39 connected to the groove 37. A connecting tube 40 with a square cross-section is provided between the isolation cup 3 and the thermos cup 2, passing through the side walls of the isolation cup 3 and the thermos cup 2. The connecting tube 40 is bonded to both the isolation cup 3 and the thermos cup 2. A connecting hose 41 is provided between the end of the connecting tube 40 extending into the isolation cup 3 and the channel 39. The connecting hose 41 is bonded to the connecting tube 40 and the suction cup 8. The length of the connecting hose 41 does not interfere with the up and down movement of the suction cup 8.

[0047] The end of the connecting tube 40 facing away from the connecting hose 41 is provided with a twist block 42 located outside the thermos cup 2. The side of the twist block 42 facing the connecting tube 40 is provided with a threaded rod 43 with a circular cross-section that extends into the connecting tube 40. The twist block 42 is bonded to the threaded rod 43. A square block 44 is provided within the connecting tube 40, through which the threaded rod 43 passes and is threadedly connected to the threaded rod 43. The four side walls of the square block 44 respectively mate with the four inner walls of the connecting tube 40. The side of the square block 44 facing away from the twist block 42 is provided with a connecting rod 45 extending along the length of the connecting tube 40. The end of the connecting rod 45 facing away from the square block 44 is provided with a square piston 46. The connecting rod 45 is bonded to both the piston 46 and the square block 44. The four side walls of the piston 46 respectively mate with the four inner walls of the connecting tube 40.

[0048] The outer wall of the thermos flask 2 is provided with an annular chute 1 (47) surrounding the connecting tube 40. A slider 1 (48) is positioned within chute 1 (47) on the side of the twisting block 42 facing chute 1 (47). Slider 1 (48) is bonded to the twisting block 42. A chute 2 (49) is positioned on the side of the chute 1 (47) facing away from the twisting block 42. This chute 1 (47) is wider than chute 1 (47) and communicates with chute 1 (47). Within chute 1 (49) is a slider 2 (50) connected to slider 1 (48). Slider 2 (50) and slider 1 (48) are integrally formed. Slider 2 (50) and slider 1 (48) act as position limiters, preventing the twisting block 42 and threaded rod 3 (43) from escaping from the connecting tube 40.

[0049] See attached for details Figure 2 , Attachment Figure 3 , Attachment Figure 6 and attached Figure 7 The top of the inner wall of the isolation cup 3 is provided with an annular baffle 12 arranged around the isolation cup 3, and the baffle 12 is compressible in the horizontal direction. The baffle 12 of this embodiment includes a plurality of arc-shaped shaping plates 51 equidistantly arranged along the annular direction of the isolation cup 3, and an elastic cloth 1 52 is provided between two adjacent shaping plates 51, and the shaping plate 51 is bonded to the elastic cloth 1 52.

The top and bottom of the shaping plate 51 are provided with an outer layer of cloth 54 connected to the inner wall of the isolation cup 3 and covering the springs 2 53, and the outer layer of cloth 54 is bonded to the shaping plate 51 and the isolation cup 3. The top surface of the outer layer of cloth 54 located at the top of the baffle 12 is provided with a drawstring 55, and the drawstring 55 is sewn to the outer layer of cloth 54.

[0050] When inserting the medicine bottle 1 into the isolation cup 3, the medicine bottle 1 is squeezed into the isolation cup 3 from the inside of the baffle 12. The medicine bottle 1 will compress the spring 2 53 in the baffle 12, and the elastic cloth 1 52 will also be stretched. Sometimes, the shaping plate 51 may be pulled into the isolation cup 3. In this case, the shaping plate 51 and spring 2 53 can be pulled back to the horizontal position by simply pulling the pull rope 55. The function of the baffle 12 is not to completely fix the medicine bottle 1. Its function is to position the medicine bottle 1 in the isolation cup 3 after entering the isolation cup 3, and at the same time, it serves to seal the isolation cup 3 and reduce the rate of heat overflow from the isolation cup 3.

The end of air tube 3 63 away from the flexible tube 62 is thicker than the end of air tube 3 63 closer to the flexible tube 62. This arrangement reduces the velocity of the hot air exiting air tube 3 63, preventing excessive air velocity from causing drops of medicine dripping from the medicine bottle 1 to deviate from their direction and prevent them from falling vertically.

[0054] The top of the top plate 14 is also provided with a support rod with adjustable height. The top of the support rod is provided with an extension rod 18 extending toward the central axis of the thermos cup 2. The end of the extension rod 18 away from the support rod is provided with a dropper 19 detachably connected to the extension rod 18. The dropper 19 is inclined 60°-70° relative to the horizontal plane. The central axes of the thermos cup 2 and the isolation cup 3 both pass through the center of the entrance of the dropper 19, so that the liquid medicine dripping from the medicine bottle 1 can enter the dropper 19.

[0055] The support rods of this embodiment include a support rod 1 64 and a support rod 2 65 inserted into the top end of the support rod 1 64 and movable along the height direction of the support rod 1 64. The support rod 1 64 is bonded to the top plate 14. Figure 12 The top of the side wall of the support rod 1 64 is provided with a threaded hole 2 66, and the threaded hole 2 66 is provided with a threaded rod 2 67 passing through the threaded hole 2 66 and abutting against the support rod 2 65, and the threaded rod 2 67 is screwed into the threaded hole 2 66. Figure 8 The side wall of the dropper 19 facing the extension rod 18 is provided with a connecting rod 68. The end of the connecting rod 68 facing the extension rod 18 is provided with a socket 69. The end of the extension rod 18 away from the support rod is provided with an insertion rod 70 that can be inserted into the socket 69. The insertion rod 70 and the extension rod 18 are integrally manufactured. The connecting rod 68 and the dropper 19 are also integrally manufactured. When installing the disposable dropper 19, simply insert the insertion rod 70 into the socket 69.

[0056] In this embodiment, the tops of both sidewalls of the isolation cup 3, which are not provided with the air inlet 6, are each provided with a window 1 71. Window 1 71 is fitted with a soft rubber sheet 1 72, which is bonded to the isolation cup 3. The tops of both sidewalls of the insulation cup 2 are each provided with a window 2 73, which is aligned with the two windows 1 71. Window 2 73 is fitted with a soft rubber sheet 2 74, which is bonded to the insulation cup 2. If necessary, a nurse can indirectly access the medicine bottle 1 by pressing on the soft rubber sheets 1 72 and 74, thereby gently squeezing the top of the medicine bottle 1 and promoting rapid dripping of the liquid medicine within the bottle 1.

[0057] The operating principle of this embodiment is as follows: during use, the medicine bottle 1 is squeezed into the isolation cup 3 from the inner side of the baffle 12, and the medicine bottle 1 is pressed so that the bottom of the medicine bottle 1 is tightly pressed against the top of the suction cup 8. At this time, the spring 1 9 and the temperature sensor chip 11 are pressed into the groove 37, and the temperature sensor chip 11 is attached to the bottom of the medicine bottle 1; then, the twist block 42 is rotated, and the square block 44 moves in the connecting tube 40 away from the isolation cup 3, pulling the piston 46 away from the isolation cup 3. After the medicine bottle 1 is sucked onto the suction cup 8, the twisting of the twist block 42 is stopped.

[0058] Then, remove the plug 17 from the third perforation 15, install the gusset plate 13 and the top plate 14 on the thermos cup 2, adjust the height of the trachea and the support rod according to the height of the medicine bottle 1, and fine-tune the third trachea 63 so that the third trachea 63 does not block the liquid outlet of the medicine bottle 1 and faces the dropper 19. Since the medicine bottle 1 is placed in the center of the isolation cup 3, the central axis of the medicine bottle 1 coincides with the central axes of the isolation cup 3 and the thermos cup 2. The central axes of the thermos cup 2 and the isolation cup 3 both pass through the center of the entrance of the dropper 19, so the medicine dropping opening of the medicine bottle 1 is aligned with the entrance of the dropper 19.

[0059] Then, the control panel 7 is turned on, and the rotating motor 20 and the heating wire 24 are turned on through the control panel 7. The rotating motor 20 drives the fan blades 23 to rotate, thereby blowing air, and the hot air heated by the heating wire 24 is sent into the isolation cup 3 through the air inlet 6, so that the isolation cup 3 is in a state of hot air; at the same time, the trapezoidal plate 33 rotates, thereby driving the protrusion 1 34 to lift and lower the protrusion 2 36, thereby shaking the medicine bottle 1, so that the liquid medicine in the medicine bottle 1 is evenly mixed, accelerating the heat transfer speed to the liquid medicine, and improving the heating efficiency; because the suction cup 8 Made of heat-insulating material, the heat in the isolation cup 3 will not quickly enter the groove 37. Therefore, the temperature sensor chip 11 is in a relatively closed state and only monitors the temperature at the bottom of the bottle. When the entire bottle of liquid medicine is evenly heated to 37°C, the temperature sensor chip 11 will continue to detect this temperature value. At this time, the control screen 7 will automatically turn off the rotating motor 20 and the heating wire 24. If the temperature of the liquid medicine drops again before the nurse uses it, the control screen 7 will automatically turn on the rotating motor 20 and the heating wire 24 to continue heating the liquid medicine.

[0060] After the nurse completes other preparations, she picks up the thermos cup 2, turns it upside down, points the dropper 19 at the patient's ear, and drips the medicine in the medicine bottle 1 into the dropper 19. The medicine then flows along the dropper 19 into the patient's ear. During this process, the trachea three 63 blows hot air toward the dropper 19. The airflow coming out of the trachea three 63 does not need to be large, it only needs to be hot air with a flow rate. This hot air will keep the medicine entering the dropper 19 warm, and at the same time promote the medicine in the dropper 19 to flow smoothly along the dropper 19 into the patient's ear.
