Description

Technical Field

[0001] The present invention relates to the technical field of ear drops administration, and particularly relates to an ear administration device. Background Art

[0002] For ear diseases such as cerumen impaction, otitis media, and external auditory canal inflammation, drugs need to be administered through the external auditory canal or the inner ear canal to achieve the purpose of treatment. Mastering the correct ear drop method can shorten the course of the disease and reduce the occurrence of adverse reactions. When a nurse drops the liquid medicine into a patient's ear, the liquid medicine cannot be directly dropped on the patient's eardrum, but should slide down along the ear wall. To avoid contamination, it is also necessary to ensure that the medicine bottle mouth does not touch the external auditory canal. In addition, before dropping the liquid medicine, it is necessary to warm the liquid medicine with warm water or the palm to avoid adverse reactions such as dizziness and nausea in the patient due to the liquid medicine being too cold.

[0003] Warming the liquid medicine with the hand not only occupies the nurse's hand, making it inconvenient for the nurse to do other preparatory work, but also has low warming efficiency, especially when the number of patients receiving ear drops is large. Heating with water requires controlling the water temperature on the one hand. The water temperature cannot be too high to avoid affecting the drug effect, and the water temperature cannot be too low either, otherwise it will affect the heating rate. Especially in winter, the warm water will cool down quickly. Therefore, the efficiency of heating the liquid medicine with hot water is also not high. In addition, when a nurse drops the liquid medicine into a patient's ear, one hand will pull the patient's auricle, and the other hand will hold the medicine bottle to drop the liquid medicine into the ear. Since the auricles of some patients are small, in the above scenario, the nurse's two hands and the medicine bottle will block part of the nurse's vision, resulting in an unobstructed view for the nurse to drop the medicine, and the nurse has to get closer to the patient's ear to accurately drop the liquid medicine according to the operation specifications. Summary of the Invention

[0004] Based on the above problems, the present invention provides an ear administration device, which can automatically heat the liquid medicine with high heating efficiency, prevent the medicine drops from getting cold when dropping the liquid medicine into the patient's ear, and at the same time can make the nurse's vision more open.

Detailed implementation manners

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and do not limit the present invention.

[0018] See the attached Figure 1 to the attached Figure 12 , an otological drug delivery device, specifically see the attached Figure 1 and the attached Figure 2 , including a thermos cup 2 and an isolation cup 3 suspended in the thermos cup 2. There is a wind cavity 4 between the isolation cup 3 and the thermos cup 2. There is an annular connecting plate 5 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 component is provided in the wind cavity 4. The top of the side wall of the isolation cup 3 is provided with evenly distributed air inlet holes 6, and the air inlet holes 6 communicate the wind cavity 4 with the inside of the isolation cup 3.

[0019] Specifically see the attached Figure 2 , the attached Figure 3 and the attached Figure 4 , the hot air component of this embodiment includes a rotary motor 20 provided at the bottom of the wind cavity 4, and the rotary motor 20 is bonded to the inner bottom surface of the thermos cup 2. The top of the rotary motor 20 is provided with a rotating rod 21 connected to the output shaft end of the rotary motor 20. The top of the rotating rod 21 is provided with a round block 22 bonded to the rotating rod 21. The side wall of the round block 22 is provided with fan blades 23, and the round block 22 and the fan blades 23 are integrally made.

[0020] The hot air component further includes a heating wire 24 surrounding 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, and the heating temperature of the heating wire 24 is about 37°C. The bottom end of the outer side wall of the thermos cup 2 is provided with ventilation holes 25 to facilitate the fan blades 23 to blow air. The rotary motor 20 drives the rotating rod 21 to rotate, the rotating rod 21 drives the fan blades 23 to rotate, and the fan blades 23 blow air towards the isolation cup 3 located above the fan blades 23. The air becomes hot air after passing through the heating wire 24, and the hot air enters the isolation cup 3 from the wind cavity 4 through the air inlet holes 6, so as to continuously heat the medicine bottle 1 in the isolation cup 3. The bottom surface of the isolation cup 3 is a spherical surface protruding towards the side where the fan blades 23 are located, which is convenient for the air to spread towards both sides of the isolation cup 3.

[0021] Specifically see the attached Figure 4 and the attached Figure 9 , the bottom surface of the isolation cup 3 is provided with a support component that can be telescoped 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. The center of the top surface of the suction cup 8 is provided with a first spring 9. The top of the first spring 9 is provided with a support piece 10. The support piece 10 is bonded to the first spring 9. The top of the support piece 10 is provided with a temperature sensing chip 11.

[0022] The outer side wall of the heat-insulating cup 2 is provided with a control screen 7. The control screen 7 is used to control the rotation motor 20 and the heating wire 24 to turn on and off, and at the same time monitor the temperature inside the isolation cup 3 detected by the temperature sensing chip 11. When the temperature is relatively high, the control screen 7 can control the rotation motor 20 and the heating wire 24 to turn off. When the temperature becomes low, it controls the rotation motor 20 and the heating wire 24 to turn on again.

[0023] See the attachment Figure 10 In this embodiment, the support assembly includes two fixed rods 26. The bottom of the fixed rod 26 is bonded to the bottom surface of the isolation cup 3. The top of the fixed rod 26 is provided with a movable cavity 27 arranged along the height direction of the fixed rod 26. Inside the movable cavity 27, there is a movable rod 28 with its top end passing through the movable cavity 27. The movable rod 28 can move along the height direction of the fixed rod 26 inside the movable cavity 27. 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 rod 26. The outer side wall of the bottom end of the movable rod 28 is provided with an annular slider 30 located inside the annular groove 29 and capable of sliding along the height direction of the annular groove 29. The annular slider 30 is bonded to the movable rod 28. Buffer pads 31 are provided on both the bottom surface and the top surface of the annular groove 29. The buffer pads 31 can reduce noise.

[0024] There is a jolting component between the bottom of the suction cup 8 and the bottom surface of the isolation cup 3 that can push the suction cup 8 to move along the height direction of the isolation cup 3. The jolting component of this embodiment includes a support rod 32 that is vertically arranged and passes through the bottom of the isolation cup 3 and is then bonded to the top of a round block 22. The top of the support rod 32 is provided with an inverted trapezoidal plate 33 arranged vertically. At both ends of the top of the trapezoidal plate 33, there are convexities 34 with spherical surfaces. The convexities 34 are bonded to the trapezoidal plate 33. On the side of each of the two movable rods 28 facing each other, there is a support block 35. The support block 35 is bonded to the movable rod 28. The bottom of the support block 35 is provided with a convexity 36 with a spherical surface. The convexity 36 is bonded to the support block 35.

[0025] When the rotation motor 20 drives the round block 22 to rotate, when the round block 22 drives the trapezoidal plate 33 to rotate, the two convexities 34 can be rotated to the side of the two convexities 36 at the same time. When the trapezoidal block continues to rotate, the two convexities 34 will respectively lift and then lower the two convexities 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 round block 22 rotates continuously, the convexity 34 will continuously lift or lower the medicine bottle 1, achieving the purpose of jolting the liquid medicine inside the medicine bottle 1. In order to reduce the noise generated by the collision between the convexity 34 and the convexity 36, a layer of soft rubber can be pasted on the surfaces of the convexity 34 and the convexity 36 to achieve the purpose of noise reduction.

[0026] The height of the annular groove 29 is sufficient for the protrusion one 34 to completely lift the protrusion two 36. At the same time, if the device is placed upside down, the movable rod 28 will drive the annular slider 30 to slide to one 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, the protrusion one 34 can no longer touch the protrusion two 36. Therefore, when the rotating motor 20 continues to operate during the nurse's administration of medicine to the patient, the trapezoidal block no longer jolts the medicine bottle 1, thus ensuring the stable operation of the nurse.

[0027] For details, see the attached Figure 3 , the attached Figure 4 and the attached Figure 5 , on the top surface of the suction cup 8 of this embodiment, there is a groove 37. On the top surface of the suction cup 8, there is a soft rubber ring 38 arranged around the groove 37. The soft rubber ring 38 is bonded to the suction cup 8. The soft rubber ring 38 can closely adhere to the bottom of the medicine bottle 1. The bottom of the first spring 9 is bonded to the center of the groove 37. When the first spring 9 is in a completely relaxed state, the first spring 9 pushes the temperature sensing chip 11 out of the groove 37. So after installing the medicine bottle 1, the medicine bottle 1 presses the first spring 9, so that the temperature sensing chip 11 can fit with the bottom surface of the medicine bottle 1.

[0028] On the outer side wall of the suction cup 8, there is a horizontally arranged channel 39 that communicates with the inside of the groove 37. Between the isolation cup 3 and the heat preservation cup 2, there is a connecting pipe 40 with a square cross-section that passes through the side walls of the isolation cup 3 and the heat preservation cup 2. The connecting pipe 40 is bonded to both the isolation cup 3 and the heat preservation cup 2. Between the end of the connecting pipe 40 extending into the isolation cup 3 and the channel 39, there is a connecting hose 41. The connecting hose 41 is bonded to both the connecting pipe 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.

[0029] At the end of the connecting pipe 40 away from the connecting hose 41, there is a torsion block 42 located outside the heat preservation cup 2. On the side of the torsion block 42 facing the connecting pipe 40, there is a round threaded rod three 43 with a circular cross-section that extends into the connecting pipe 40. The torsion block 42 is bonded to the round threaded rod three 43. Inside the connecting pipe 40, there is a square block 44 for the round threaded rod three 43 to pass through and threadedly engage with. The four side walls of the square block 44 are respectively in contact with the four inner walls of the connecting pipe 40. On the side of the square block 44 away from the torsion block 42, there is a connecting rod 45 arranged along the length direction of the connecting pipe 40. At the end of the connecting rod 45 away from the square block 44, there is 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 are respectively in contact with the four inner walls of the connecting pipe 40.

[0030] On the outer side wall of the heat-insulating cup 2, there is a circular sliding groove one 47 arranged around the connecting pipe 40. On the side of the torsion block 42 facing the sliding groove one 47, there is a sliding block one 48 located in the sliding groove one 47. The sliding block one 48 is bonded to the torsion block 42. On the side of the sliding groove one 47 away from the torsion block 42, there is a sliding groove two 49 communicated with the sliding groove one 47 and having a width greater than that of the sliding groove one 47. In the sliding groove two 49, there is a sliding block two 50 connected to the sliding block one 48. The sliding block two 50 and the sliding block one 48 are integrally made. The sliding block two 50 and the sliding block one 48 play a role in limiting, preventing the torsion block 42 and the threaded rod three 43 from disengaging from the connecting pipe 40.

[0031] See the attachment specifically Figure 2 , attachment Figure 3 , attachment Figure 6 and attachment Figure 7 , at the top of the inner side wall of the isolation cup 3, there is a circular baffle 12 arranged around the isolation cup 3. The baffle 12 can be compressed in the horizontal direction. The baffle 12 in this embodiment includes a plurality of arc-shaped shaping plates 51 arranged at equal intervals along the circumferential direction of the isolation cup 3. Between two adjacent shaping plates 51, there is an elastic cloth one 52. The shaping plate 51 is bonded to the elastic cloth one 52. Between each shaping plate 51 and the inner side wall of the isolation cup 3, there are a plurality of horizontally arranged spring two 53. The spring two 53 is bonded to both the isolation cup 3 and the shaping plate 51. At the top and bottom of the shaping plate 51, there is an outer layer cloth 54 connected to the inner side wall of the isolation cup 3 and covering the spring two 53. The outer layer cloth 54 is bonded to both the shaping plate 51 and the isolation cup 3. On the top surface of the outer layer cloth 54 at the top of the baffle 12, there is a pull rope 55. The pull rope 55 is sewn to the outer layer cloth 54.

[0032] When the medicine bottle 1 is stuffed into the isolation cup 3, just let the medicine bottle 1 squeeze into the isolation cup 3 from the inside of the baffle 12. The medicine bottle 1 will compress the spring two 53 in the baffle 12, and the elastic cloth one 52 will also be stretched open. Sometimes, it may drive the shaping plate 51 into the isolation cup 3. At this time, just pull the pull rope 55 to pull the shaping plate 51 and the spring two 53 back to the horizontal position. The function of the baffle 12 is not to completely fix the medicine bottle 1. Its function is to make the medicine bottle 1 located at the center position of the isolation cup 3 after entering the isolation cup 3, and at the same time play a role in closing the isolation cup 3 and reducing the heat overflow rate in the isolation cup 3.

[0033] See the attachment specifically Figure 2 and attachment Figure 6 , at the top of the outer side wall of the heat-insulating cup 2, there is a circular buckle plate 13 arranged around the heat-insulating cup 2 and detachably connected to the heat-insulating cup 2.

The first threaded hole 60 is provided with a first threaded rod 61 that passes through the first threaded hole 60 and one end abuts against the air pipe one 58. The first threaded rod 61 is threadedly connected with the first threaded hole 60. One end of the air pipe two 59 away from the heat preservation cup 2 is provided with a bendable pipe 62 made of elastic plastic. One end of the bendable pipe 62 away from the air pipe two 59 is provided with an air pipe three 63. The bendable pipe 62 is bonded to both the air pipe two 59 and the air pipe three 63. One end of the air pipe three 63 away from the bendable pipe 62 is thicker than one end of the air pipe three 63 closer to the bendable pipe 62. The reason for such a setting is that it can reduce the wind speed of the hot air coming out of the air pipe three 63, avoid the wind speed being too large and causing the medicine drops dripping out of the medicine bottle 1 to deviate from the direction and not fall vertically.

[0036] The top of the top plate 14 is also provided with a support rod that can adjust the height. The top end of the support rod is provided with an extension rod 18 extending towards the central axis of the heat preservation cup 2. One 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 heat preservation 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 out of the medicine bottle 1 can enter the dropper 19.

[0037] The support rod in this embodiment includes a support rod one 64 and a support rod two 65 inserted into the top end of the support rod one 64 and movable along the height direction of the support rod one 64. The support rod one 64 is bonded to the top plate 14, see attached Figure 12 , the top end of the side wall of the support rod one 64 is provided with a second threaded hole 66. The second threaded hole 66 is provided with a second threaded rod 67 that passes through the second threaded hole 66 and abuts against the support rod two 65. The second threaded rod 67 is threadedly connected with the second threaded hole 66. See attached Figure 8, the side wall of the dropper 19 facing the extension rod 18 is provided with a connecting rod 68. One end of the connecting rod 68 facing the extension rod 18 is provided with a socket 69. One end of the extension rod 18 away from the support rod is provided with a plug rod 70 that can be inserted into the socket 69. The plug rod 70 and the extension rod 18 are integrally made, and the connecting rod 68 and the dropper 19 are integrally made. When installing the disposable dropper 19, just insert the plug rod 70 into the socket 69.

[0038] At the top of the side walls on both sides where the isolation cup 3 of this embodiment is not provided with air inlet holes 6, there are windows one 71. The windows one 71 are provided with soft rubber cloth one 72, and the soft rubber cloth one 72 is bonded to the isolation cup 3. At the top of the side walls on both sides of the heat preservation cup 2, there are windows two 73. The two windows two 73 are directly opposite to the two windows one 71. The windows two 73 are provided with soft rubber cloth two 74, and the soft rubber cloth two 74 is bonded to the heat preservation cup 2. In necessary cases, the nurse can indirectly contact the medicine bottle 1 by pressing the soft rubber cloth one 72 and the soft rubber cloth two 74, so as to gently squeeze the top of the medicine bottle 1 to promote the rapid dripping of the liquid medicine in the medicine bottle 1.

[0039] The working principle of this embodiment is as follows: When in use, squeeze the medicine bottle 1 from the inside of the baffle 12 into the isolation cup 3, press the medicine bottle 1 so that the bottom of the medicine bottle 1 tightly presses on the top of the suction cup 8. At this time, the first spring 9 and the temperature sensing chip 11 are pressed into the groove 37, and the temperature sensing chip 11 is attached to the bottom of the medicine bottle 1; then rotate the torsion block 42, and the square block 44 moves away from the isolation cup 3 in the connecting pipe 40, pulling the piston 46 away from the isolation cup 3 until the medicine bottle 1 is sucked on the suction cup 8, and then stop twisting the torsion block 42; Then remove the plug 17 in the third through hole 15, install the buckle plate 13 and the top plate 14 on the heat preservation cup 2, adjust the height of the air pipe and the support rod according to the height of the medicine bottle 1, and finely adjust the air pipe three 63 so that the air pipe three 63 does not block the liquid outlet part of the medicine bottle 1, and at the same time make the air pipe three 63 face 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 heat preservation cup 2, and the central axes of the heat preservation cup 2 and the isolation cup 3 both pass through the center of the inlet of the dropper 19, so the dropping port of the medicine bottle 1 is aligned with the inlet of the dropper 19; After that, turn on the control panel 7. Through the control panel 7, turn on the rotary motor 20 and the heating wire 24. The rotary motor 20 drives the fan blade 23 to rotate, thereby blowing air. The hot air heated by the heating wire 24 is sent into the isolation cup 3 through the air inlet hole 6, making the inside of the isolation cup 3 in a state of swirling hot air. At the same time, the trapezoidal plate 33 rotates, thereby driving the protrusion one 34 to lift and lower the protrusion two 36, thereby jolting the medicine bottle 1, making the liquid medicine in the medicine bottle 1 mixed evenly, accelerating the heat transfer speed to the liquid medicine, and improving the heating efficiency. Because the suction cup 8 is made of heat-insulating material, the hot air in the isolation cup 3 will not quickly enter the groove 37. Therefore, the temperature sensing chip 11 is in a relatively closed state. It only monitors the temperature of the bottom of the bottle. When the whole bottle of liquid medicine is evenly heated to 37 °C, the temperature sensing chip 11 will continuously detect this temperature value. At this time, the control panel 7 will automatically turn off the rotary motor 20 and the heating wire 24. Before the nurse uses it, if the temperature of the liquid medicine drops, the control panel 7 will automatically turn on the rotary motor 20 and the heating wire 24 to continue heating the liquid medicine; After the nurse has completed other preparatory work, pick up the thermos cup 2 and make the thermos cup 2 in an inverted state. The dropper 19 is aligned with the patient's ear, and the liquid medicine in the medicine bottle 1 drips into the dropper 19. The liquid medicine drips into the patient's ear along the dropper 19. During this process, the air pipe three 63 blows hot air towards the dropper 19. The airflow coming out of the air pipe three 63 does not need to be very large, as long as it is hot air and has a flow rate. This hot air will keep the liquid medicine entering the dropper 19 warm and at the same time promote the smooth flow of the liquid medicine in the dropper 19 into the patient's ear.
