Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to an ear channel medicine dropping device. BACKGROUND
[0002] For diseases in the ear channel, medicine is usually dropped into the ear channel for treatment. When medicine is dropped into the ear channel, the patient is best to lie flat, expose the affected ear upward, pull the auricle upward with one hand (if it is a child, the auricle can be pulled downward) to straighten the ear channel, then drop 5-6 drops of the eardrop (if it is a child, 2-3 drops can be dropped) with one hand, keep the affected ear upward for several minutes to ensure that the medicine fully plays a role. In this process, the tragus can be repeatedly pressed with the hand to make the medicine enter the deep part of the ear channel.
[0003] For adults with self-control, the head can be kept still to ensure that the medicine fully plays a role in the ear channel, but for children and other patients without self-control or with poor self-control, it is difficult to control the head to keep still, for example, children are prone to crying when medicine is dropped into the ear channel due to fear, it is difficult to drop the medicine into the ear channel, and even if the medicine is forcibly dropped into the ear channel, the child can also lose control of emotions to cause the head to move, so for this kind of patient, after the medicine is dropped into the ear channel, the medicine is prone to quickly flow out of the ear channel, resulting in limited drug effect. CONTENT OF THE UTILITY MODEL

[0035] The embodiments of the present application will be described below in combination with Figures 1-9 The utility model will be described in detail.
[0036] An ear canal medicine dropping device, such as Figures 1-6As shown, including earplug body, the earplug body includes hard tube 11 and waterproof sleeve 1 set on the hard tube 11, waterproof sleeve 1 is flexible silicone sleeve in this embodiment, follow the shape change and it has waterproof, not water absorption, avoid the waste of liquid medicine, and the hard tube 11 is hard plastic tube, it is hard material for the sliding and rotation of the medicine rod 2; The hard tube 11 and waterproof sleeve 1 are provided with medicine outlet 4 in communication with the hard tube 11, the hard tube 11 is slidably connected with the medicine rod 2, the medicine rod 2 can be driven to rotate or slide in the hard tube 11 by holding the medicine rod 2 with hand; The medicine rod 2 is provided with medicine storage cavity 12, one end of the medicine rod 2 is provided with medicine inlet 6 in communication with the medicine storage cavity 12, the other end of the medicine rod 2 is provided with medicine outlet 10 in communication with the medicine storage cavity 12, the medicine rod 2 can be rotated in the hard tube 11 to communicate the medicine outlet 10 with the medicine outlet 4. It should be noted that when the medicine rod 2 is inserted into the hard tube 11, the inner wall of the hard tube 11 can block the medicine outlet 10 and the medicine inlet 6 to achieve the plugging of the liquid medicine in the medicine storage cavity 12. In this embodiment, the whole device is disposable, and each earplug body is individually sterile packaged during production, and one can be used each time, avoiding contamination.
[0037] In this embodiment, the main body 101 of the waterproof sleeve 1 is cylindrical, and one end of the cylindrical main body 101 is provided with a semicircular spherical protrusion 102, and the medicine outlet 4 is arranged on the arc surface of the semicircular spherical protrusion 102.
[0038] In this embodiment, as shown in the figure, Figures 4-6 The medicine outlet 10 is arranged on the side surface of the end portion of the medicine rod 2, and the medicine outlet 10 and the medicine outlet 4 are both inclined structures, and the inclination degrees are equal. The medicine outlet 10 is arranged on the arc surface of the semicircular spherical protrusion 101, and the arc surface of the semicircular spherical protrusion 101 does not contact the skin of the ear canal after the earplug body is inserted into the ear canal, which can ensure the smooth flow of the liquid medicine. Figures 4-6 It can be seen that the medicine outlet 10 and the medicine inlet 6 can form a smooth liquid flow channel.
[0039] When the device is used, the medicine rod 2 can be pulled out of the hard tube 11 (from the ear canal) under the condition that the medicine outlet 10 and the medicine outlet 10 are not on the same straight line. Figure 1 becomes Figure 2The medicine outlet 6 leaks, and then a certain amount of medicine is added to the medicine inlet 6 (it should be noted that the amount of medicine added here can consider the loss of medicine caused by the flow of medicine in the device, so it can be added in excess to ensure sufficient dosage), after the addition is completed, the medicine delivery rod 2 is pushed to make the medicine delivery rod 2 enter the hard tube 11, at this time the side wall of the hard tube 11 blocks the medicine outlet 6 and the medicine inlet 6, and the medicine cannot flow out, then the earplug body is inserted into the user's ear canal (the patient is in a lateral position at this time, and the affected ear is upward, and it should be noted that the earplug body is not completely inserted into the ear canal at this time, so that the earplug body has a certain gap with the ear canal, to ensure that the medicine can be smoothly discharged from the medicine delivery rod 2), the medicine delivery rod 2 is rotated to make the medicine outlet 6 of the medicine delivery rod 2 communicate with the medicine outlet 6, and the medicine flows out from the medicine outlet 6 to the patient's ear canal through the medicine outlet 6, then the earplug body is further inserted into the user's ear canal, so that the earplug body is completely attached to the ear canal, at this time, due to the blocking of the earplug body to the ear canal, even if the user moves the head, it is not easy to cause the medicine to flow out, in order to avoid the medicine flowing back to the medicine storage cavity 12 during the movement, the medicine delivery rod 2 can be rotated again to block the medicine outlet 6 of the hard tube 11.
[0040] In other embodiments, as shown in Figure 7 The outer wall of the cylindrical body 101 is provided with a plurality of anti-skid conical frustums 13. It should be noted that the anti-skid conical frustums 13 are also made of waterproof silica gel material and have a certain plasticity; the anti-skid conical frustums 13 can increase the contact surface between the earplug body and the ear canal, thereby increasing the friction and improving the connection effect of the earplug body.
[0041] In other embodiments, as shown in Figure 8 The width of the anti-skid conical frustum 13 gradually increases from the end connected to the cylindrical body 101 and the semispherical protrusion 102. By setting the width of the anti-skid conical frustum 13 to gradually increase, the application range of the device can be increased.
[0042] In other embodiments, as shown in Figure 9 The end of the medicine delivery rod 2 close to the medicine inlet 6 is provided with a knob 3, the end face of the knob 3 is provided with an arrow mark 9, the end face of the earplug body is provided with a communication mark 7 corresponding to the position of the medicine outlet 4, and the end face of the earplug body is provided with a closing mark 8 away from the communication mark 7. The knob 3 can help the user to exert force and facilitate the rotation of the medicine delivery rod 2, and the cooperation of the arrow mark 9, the communication mark 7 and the closing mark 8 can clearly know whether the medicine outlet 10 is in communication with the medicine outlet 6.
[0043] In other embodiments, the waterproof sleeve 1 is provided with a clamping groove 5 for clamping the knob 3. The knob 3 is connected with the earplug body through the clamping groove 5, which can avoid accidental touch of the knob.
[0044] The above embodiments only express the specific implementation of the present application, which is described in more detail and specifically, but cannot be understood as a limitation to the protection scope of the present application. It should be noted that for those skilled in the art, without departing from the technical concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
