Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to an ear canal medicine applicator. Background Art
[0002] When treating ear canal diseases such as otitis externa, it is often necessary to apply medication deep into the ear canal. It is easier to apply liquid medication. The patient tilts his head to one side and drops the medication into the ear canal. The medication can then flow deep into the ear canal. Alternatively, the tragus can be pressed several times to allow the medication to flow deep into the ear canal.
[0003] However, when treating fungal infections of the external auditory canal, the drugs are mostly in the form of pastes, which cannot automatically flow into the deep part of the ear canal due to their poor fluidity. Utility Model Content
[0004] The present application provides an ear canal medicine applicator, which can effectively solve the problem that paste medicines cannot be accurately applied to the diseased area.

[0008] A pushing component, at least partially disposed in the chamber, for pushing the ointment in the chamber toward the discharge port;
[0009] The flexible part has a fine pipe inside. One end of the flexible part is connected to the end of the medicine feeding tube and communicates with the chamber and the fine pipe through the discharge port. The other end of the flexible part forms a medicine feeding port connected to the fine pipe. The surface of the flexible part is formed with a scale based on the medicine feeding port.
[0010] In the above scheme, an ear canal applicator is provided, which can deliver paste medicine, that is, ointment, deep into the ear canal. Exemplarily, when using the ear canal applicator, the ointment tube can be docked with the joint, and the ointment in the ointment tube can be squeezed into the cavity of the medicine tube by squeezing, and then the pushing component works to push the ointment into the small pipe of the flexible part, and finally discharged from the medicine port. Before the ointment is discharged, the medical staff can place the flexible part deep into the ear canal. Since the flexible part is soft in texture, on the one hand, it can be bent to reach the deep ear canal, and on the other hand, it can reduce the patient's discomfort caused by the insertion of foreign objects in the ear canal; at the same time, because the surface of the flexible part is provided with a scale, the insertion depth of the flexible part can be understood for reference by the medical staff. In some embodiments, a container for storing a certain amount of ointment can be specially designed, and the container is docked with the joint through a hose to raise the ointment to the upper medicine tube. At the same time, in some of the embodiments, the ear canal applicator can be used multiple times, that is, a container storing a certain amount of plaster can provide multiple medication services to multiple patients or one patient. Because of multiple medication applications, the ointment remaining in the small pipe and being wasted can be evenly divided, thereby achieving the purpose of saving.
[0011] According to some embodiments of the present application, an inner wall of the connector is formed with an internal thread for matching with an external thread of the ointment tube.

[0023] The peripheral wall of the driving member is detachably connected to the second end, and the driving member is connected to the rotating shaft and drives the rotating shaft to rotate.
[0024] In the above scheme, the pushing component can be regarded as a dragon conveying structure, which is driven by the driving member so that the rotation drives the spiral blade to rotate. The rotation of the spiral blade can squeeze the ointment toward the discharge port to be discharged into a small pipe, and the ointment is finally delivered into the deep ear canal through continuous squeezing.
[0025] According to some embodiments of the present application, the ear canal applicator further includes an otoscope probe and a bracket, and the otoscope probe is mounted on the wall of the flexible member through the bracket.
[0026] In the above scheme, by setting up an otoscope probe, when the flexible member is placed deep into the ear canal, the specific position of the flexible member in the ear canal can be understood on the screen through the signal output by the otoscope probe, so as to achieve the purpose of accurate medication.

Figure 2 This is a schematic diagram of the internal structure of the ear canal medicine applicator 100 in some embodiments of the present application. Figure 3 This is a schematic diagram of the upper medicine tube 10 in some embodiments of the present application.
[0045] The ear canal medicine applicator 100 includes a medicine applicator tube 10, a push assembly 20 and a flexible member 30. The medicine applicator tube 10 has a chamber inside, and the wall of the medicine applicator tube 10 is provided with a joint 11 connected to the chamber, and the joint 11 is used for feeding the ointment, and the end of the medicine applicator tube 10 is provided with a discharge port 12 connected to the chamber. The push assembly 20 is at least partially disposed in the chamber, and is used to push the ointment in the chamber toward the discharge port 12. The flexible member 30 has a small pipe 31 inside, one end of the flexible member 30 is connected to the end of the medicine applicator tube 10 and connects the chamber and the small pipe 31 through the discharge port 12, and the other end of the flexible member 30 forms a medicine applicator port 32 connected to the small pipe 31, and the surface of the flexible member 30 is formed with a scale 33 based on the medicine applicator port 32.
[0046] In some embodiments, the pushing assembly 20 may be completely located in the chamber, or may be partially located in the chamber. In some embodiments, the flexible member 30 may be a tubular structure made of medical plastic with a relatively soft texture.
[0047] When treating ear canal diseases such as external otitis, it is often necessary to apply medicine deep into the ear canal. It is easier to apply liquid medicine. The patient tilts his head to one side and drops the medicine into the ear canal. The medicine can flow deep into the ear canal. You can also press the tragus several times to make the medicine flow deep into the ear canal. However, when treating fungal diseases of the external ear canal, the medicine is mostly in the form of paste. Paste medicine has poor fluidity and cannot automatically flow into the deep ear canal.
[0048] In the above scheme, an ear canal medicine applicator 100 is provided, which can deliver paste medicine, that is, ointment, deep into the ear canal. Exemplarily, when using the ear canal medicine applicator 100, the ointment tube can be docked with the connector 11, and the ointment in the ointment tube can be squeezed into the chamber of the medicine tube 10 by squeezing, and then the push component 20 works to push the ointment into the small pipe 31 of the flexible member 30, and finally discharged from the medicine port 32. Before the ointment is discharged, the medical staff can place the flexible member 30 deep into the ear canal. Since the flexible member 30 is soft in texture, it can be bent to reach the deep ear canal on the one hand, and can reduce the patient's discomfort caused by the insertion of foreign objects into the ear canal on the other hand; at the same time, since the surface of the flexible member 30 is provided with a scale 33, the insertion depth of the flexible member 30 can be understood for reference by the medical staff. In some embodiments, a container for storing a certain amount of ointment can be specially designed, and the container is docked with the connector 11 through a hose to raise the ointment to the upper medicine tube 10. At the same time, in some embodiments, the ear canal medicine applicator 100 can be used multiple times, that is, a container storing a certain amount of plaster can provide multiple medicine application services to multiple patients or one patient. Because of multiple medicine applications, the wasted ointment remaining in the small pipe 31 can be evenly divided, thereby achieving the purpose of saving.
[0049] According to some embodiments of the present application, the inner wall of the connector 11 is formed with an internal thread for matching with the external thread of the ointment tube. Figure 1The ointment tube is shown at reference numeral A in FIG.
[0050] In the above scheme, the ear canal applicator 100 can be connected with the current ointment tube (a tubular structure storing ointment, that is, an ointment product that can be purchased on the market, which usually includes a main body and a cover body, the ointment is stored in the main body, a flange structure is provided at the end of the main body, the middle part of the flange structure is the opening of the main body, the ointment can be squeezed out by squeezing the main body, and the cover body is screwed to the flange structure to close the opening). The medical staff removes the cover body of the ointment tube, connects the flange structure of the ointment tube with the joint 11, and can squeeze the ointment into the applicator tube 10 by squeezing the main body of the ointment tube.
[0051] According to some embodiments of the present application, a convex portion 13 is formed at the end of the upper medicine tube 10, and the discharge port 12 is formed at the convex portion 13. The flexible member 30 is plug-fitted with the convex portion 13.
[0052] In the above scheme, by providing the convex portion 13 at the end of the upper medicine tube 10 and making the flexible member 30 plug and match with the convex portion 13, the flexible member 30 can be detachably connected to the upper medicine tube 10, so that the flexible member 30 is a replaceable component, which is convenient for replacing the flexible member 30 in contact with the patient after each use, thereby reducing the risk of cross infection. In some embodiments, the flexible member 30 can be made of medical plastic brake, which has the characteristics of soft texture and elasticity, and can be tightly wrapped around the outer periphery of the convex portion 13, so that the flexible member 30 and the upper medicine tube 10 have a stable connection relationship.
[0053] According to some embodiments of the present application, along the axial direction of the upper medicine tube 10, the upper medicine tube 10 has a first end and a second end that are relatively arranged, and along the direction from the second end to the first end, the inner diameter of the first end gradually decreases, and the discharge port 12 is formed on the end surface of the first end away from the second end.
[0054] In the above solution, by setting the first end to be conical, the ointment in the upper medicine tube 10 is facilitated to gather at the first end and quickly flow into the ear canal through the small channel 31 under the push of the pushing component 20.

A portion of the pushing component 20 is located in the chamber and is used to push the ointment. The portion of the pushing component 20 is detachably connected to the second end.
[0056] In the above solution, by setting the second end to be open and limiting the push assembly 20 to be detachably connected to the second end, it is convenient to remove the push assembly 20 and clean the push assembly 20 and the interior of the upper medicine tube 10.
[0057] According to some embodiments of the present application, the pushing assembly 20 includes a driving member 21, a rotating shaft 22, and a spiral blade 23 disposed on the rotating shaft 22. The rotating shaft 22 is disposed in the chamber, and the rotating shaft 22 extends along the axial direction of the upper medicine tube 10.
[0058] The peripheral wall of the driving member 21 is detachably connected to the second end. The driving member 21 is connected to the rotating shaft 22 and drives the rotating shaft 22 to rotate.
[0059] In the above scheme, the pushing assembly 20 can be regarded as a Jiaolong conveying structure, which is driven by the driving member 21, so that the rotation drives the spiral blade 23 to rotate. The rotation of the spiral blade 23 can squeeze the ointment toward the discharge port 12 to be discharged into the small pipe 31, and the ointment is finally sent deep into the ear canal through continuous squeezing. In some embodiments, the rotating shaft 22 extends to the discharge port 12, and the spiral blade 23 also extends to the discharge port 12 to improve the squeezing efficiency of the ointment. In some embodiments, the driving member 21 includes a motor, and the housing of the motor can be clamped to the second end, or the housing of the motor can be screwed to the second end.
[0060] According to some embodiments of the present application, the ear canal medicine applicator 100 further includes an otoscope probe 40 and a bracket 41 , and the otoscope probe 40 is mounted on the wall of the flexible member 30 via the bracket 41 .
[0061] In the above scheme, by setting the otoscope probe 40, when the flexible member 30 is inserted deep into the ear canal, the specific position of the flexible member 30 in the ear canal can be understood on the screen through the signal output by the otoscope probe 40, so as to achieve the purpose of accurate medication. In some embodiments, the otoscope probe 40 can adopt a 3.5mm otoscope probe 40 on the market, which is small in size and meets the needs of insertion into the ear canal. In some embodiments, the cable of the otoscope probe 40 can be fixed to the peripheral wall of the medication tube 10 to restrain the cable and reduce the interference of the cable to medical personnel. The cable of the otoscope probe 40 is used for signal transmission, and the cable can be plugged into the computer screen.
[0062] According to some embodiments of the present application, the bracket 41 is sleeved on the flexible member 30 , and a slot is formed at the end of the bracket 41 , and the otoscope probe 40 is snapped into the slot.
[0063] In the above solution, the bracket 41 can be made of plastic, and is provided with a through hole for the flexible member 30 to pass through, so that the bracket 41 is placed on the peripheral wall of the flexible member 30. The otoscope probe 40 can be snapped into the slot, so as to be installed on the flexible member 30 and placed deep into the ear canal with the flexible member 30.
[0064] According to some embodiments of the present application, the ear canal medicine applicator 100 further includes a medical mirror 50 , which is adjustably disposed on the peripheral wall of the medicine applicator tube 10 along the axial direction of the medicine applicator tube 10 .
[0065] In the above solution, the medical mirror 50 can be a small magnifying glass. By providing the medical mirror 50, it is convenient for medical staff to understand the situation in the ear canal. By setting the medical mirror 50 in an adjustable position, it is convenient for medical staff to adjust the position of the medical mirror 50 to understand the situation in the ear canal.

[0067] In some embodiments, the positioning ring 51 can be made of rubber, and the upper medicine tube 10 can be made of glass or hard plastic. While the positioning ring 51 can be slidably matched with the upper medicine tube 10, there can also be a certain damping between the positioning ring 51 and the upper medicine tube 10, so that the position of the medical mirror 50 relative to the upper medicine tube 10 is more stable.
[0068] In the above solution, the medical mirror 50 can slide along the axial direction of the upper medicine tube 10 with the positioning ring 51. At the same time, the medical mirror 50 can rotate based on the positioning ring 51, thereby providing medical personnel with different perspectives to observe the internal conditions of the ear canal.
