Description

Technical Field

[0001] The present invention particularly relates to a portable eye medication auxiliary tool. Background Art

[0002] Ophthalmologists point out that people in middle and old age are more susceptible to eye diseases due to the aging of certain parts of the body. These diseases are different from normal physiological aging and can be cured if discovered and treated in time. Common eye diseases are mostly presbyopia, cataracts, and glaucoma. Most of them require the use of eye drops during the treatment process. When applying medication to the eyes, in order to avoid the eyes closing due to stress response and improve the efficiency of medication application, it is necessary to use relevant tools to assist.

[0003] Chinese patent No. 201921220516.1 provides an auxiliary device for easily applying eye drops. The device is placed on the patient's eyelids, and the two rings are squeezed. The two eye-turning blocks will turn the eyelids open, making it impossible for the patient to close or blink. The eye drops bottle is squeezed to drip the eye drops into the patient's eyes. However, since most patients with eye diseases are elderly, their finger strength is often difficult to control accurately. As a result, when squeezing the eye drops bottle, either the force applied is insufficient, resulting in the liquid not being squeezed out, or the force applied is too great, resulting in an excessive amount of liquid being squeezed out. It is impossible to quickly and quantitatively squeeze the liquid in the bottle according to needs, making eye medication still somewhat inconvenient. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention proposes a portable eye medication auxiliary tool to solve the technical problem raised in the above background technology that most patients with eye diseases are elderly people, and the strength of their fingers cannot be accurately controlled.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When using this medication-applying auxiliary tool, the shifting assembly first limits the rotation angle of the mounting barrel, the patient tilts their head back, holds the housing with one hand, makes the bottle body of the medicine bottle vertical, and places the medicine tube directly above the eyeball. The thumb turns the control wheel to rotate to drive the mounting disk at one end of the mounting barrel to rotate, thereby causing the inclined block on one side of the mounting disk to move. The inclined surface of the inclined block pushes the squeezing mechanism to move and squeeze the medicine bottle, so that the liquid medicine in the bottle is squeezed out for eye medication. The shifting assembly can also be used to adjust the rotation amplitude of the mounting barrel, thereby adjusting the movement distance of the squeezing mechanism, and thus adjusting the amount of liquid medicine squeezed out each time in stages. The medication application is convenient and quick, effectively preventing elderly patients from squeezing out too little or too much liquid medicine due to uncontrolled hand force, thereby improving the efficiency of medication application for elderly patients.

[0043] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0044] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0045] Example:

[0046] like Figures 1 to 3 As shown in Figures 6 and 7, the present invention provides a portable ophthalmic medication application aid, primarily for elderly patients, but also for other patients with limited hand control. The device comprises a housing 101, within which is disposed a medicine bottle 408. A medicine outlet tube 409 is disposed at one end of the medicine bottle 408, extending through the housing 101 and extending externally.

[0047] like Figure 2 、 4As shown in Figures 8 and 10, in this embodiment, a rotatable mounting cylinder 105 is provided on the housing 101. A control wheel 106 is provided on one end of the mounting cylinder 105 exposed to the outside, and a mounting disk 110 is provided on the other end. A ramp block 107 is provided on the mounting disk 110. A squeezing mechanism is provided on the housing 101, and the squeezing mechanism contacts the medicine bottle 408. The squeezing mechanism includes a second squeezing plate 201 and a first squeezing plate 203. The mounting disk 110 is provided between the first squeezing plate 203 and the housing 101. The first squeezing plate 203 and the second squeezing plate 201 are connected by a connecting column 202. The housing 101 is provided with multiple groups of connecting holes 302. The connecting column 202 can be slidably arranged in the connecting hole 302 along its axis. The first squeezing plate 203 and the second squeezing plate 201 are arranged in parallel and are respectively located on the inner and outer sides of the housing 101. An extrusion block 205 is provided on one side of the first extrusion plate 203 , and the extrusion block 205 is in contact with the medicine bottle 408 . A second elastic pad 204 is provided between the second extrusion plate 201 and the shell 101 .

[0048] Rotating the control wheel 106 drives the mounting plate 110 to move between the first extrusion plate 203 and the housing 101. The inclined surface of the inclined block 107 on one side of the mounting plate 110 gradually pushes the first extrusion plate 203 inward within the housing 101. The extrusion block 205 squeezes the medicine bottle 408, causing it to deform and allowing the liquid in the bottle 408 to drip out through the medicine outlet tube 409 for rapid eye medication. The second extrusion plate 201, in conjunction with the connecting post 202, limits the trajectory and range of motion of the first extrusion plate 203.

[0049] A spiral spring piece 104 is sleeved on the mounting tube 105, and the two ends of the spiral spring piece 104 are fixedly connected to the mounting tube 105 and the shell 101 respectively. The deformation of the spiral spring piece 104 is controlled during the medication application process. After the medication application is completed, the spiral spring piece 104 is reset to drive the control wheel 106 to reverse, and the second elastic pad 204 controls the squeezing block 205, the second squeezing plate 201 and the first squeezing plate 203 to reset, making it more convenient and quick to apply medication on the patient's eyes.

[0050] like Figure 3 、 4 As shown in Figures 6 and 7, in this embodiment, a gear shifting assembly is provided in the mounting cylinder 105, and the gear shifting assembly includes a mounting column 501, and the mounting column 501 is rotatably provided in the mounting cylinder 105. A gear shifting knob 502 is provided at one end of the mounting column 501 exposed to the outside, and a control disk 503 is provided at the other end. A shift rod 505 and a fixed column 504 are provided on the control disk 503. A limiting plate 109 for limiting the movement range of the shift rod 505 is provided in the shell 101. A plurality of gear holes 108 are provided on the mounting cylinder 105, and the fixed column 504 is clamped in one of the gear holes 108. A first elastic pad 506 is provided between the gear shifting knob 502 and the control wheel 106.

[0051] The shift knob 502 can be pressed inward to disengage the fixed post 504 from the shift hole 108, and then the shift knob 502 can be turned to drive the control disk 503 to rotate, and the fixed post 504 can be aligned with the corresponding shift hole 108 according to the amount of medicine applied. Then the shift knob 502 can be released, and the shift knob 502 and the control disk 503 can be reset under the action of the first elastic pad 506, so that the fixed post 504 is stuck in the corresponding shift hole 108 to adjust the initial position of the shift rod 505 in the shell 101. In the process of rotating the control wheel 106, the control disk 503 can be driven to rotate until the shift rod 505 contacts the limit plate 109 and cannot rotate. The rotation angle of the mounting cylinder 105 can be adjusted in stages, thereby adjusting the movement distance of the squeezing mechanism in stages, so as to achieve the purpose of controlling the amount of medicine dripping out in stages, making it more convenient and efficient for elderly patients who have difficulty in controlling the force of their hands to apply eye medicine.

[0052] like Figure 8 、 10 As shown, in this embodiment, the extrusion block 205 is connected to the first extrusion plate 203 via an adjustment assembly to adjust the distance between the extrusion block 205 and the first extrusion plate 203. The adjustment assembly includes a threaded knob 208 that is rotatably disposed on the first extrusion plate 203 and threadedly engaged therewith. One end of the threaded knob 208 is rotatably connected to the extrusion block 205. A first through-slot 209 is defined in the second extrusion plate 201, and a second through-slot 301 is defined in the housing 101. The other end of the threaded knob 208 passes through the first through-slot 209 and the second through-slot 301 and is exposed outside the housing 101.

[0053] The threaded knob 208 can be rotated at one end exposed outside the shell 101. During the rotation of the threaded knob 208, the extrusion block 205 is driven to move on one side of the first extrusion plate 203 through the threaded cooperation with the first extrusion plate 203, and a positioning column 206 is provided on the extrusion block 205. A positioning hole 207 is opened on the first extrusion plate 203, and the positioning column 206 is passed through the positioning hole 207. The movement of the extrusion block 205 is positioned by the cooperation between the positioning hole 207 and the positioning column 206, so that the extrusion block 205 can move horizontally and contact the outer wall of the medicine bottle 408 of different sizes, thereby improving the applicability of the tool.

[0054] like Figure 4 、 5As shown in Figures 10 and 10, in this embodiment, a locking assembly is provided on the housing 101, and the locking assembly includes a locking buckle 304. A locking groove 303 is provided on the housing 101, and the locking buckle 304 is disposed in the locking groove 303 and has an interference fit therewith. The locking buckle 304 can slide along both ends of the locking groove 303 to fix or release the position of the first extrusion plate 203. When not in use, the locking buckle 304 can be slid downward along the locking groove 303 so that it is locked on the first extrusion plate 203 to fix its position. This prevents the medicine bottle 408 from deforming and causing leakage of the medicine liquid when accidentally touching the second extrusion plate 201 during carrying. When it is needed, the locking buckle 304 can be moved upward to disengage it from the first extrusion plate 203.

[0055] like Figure 1 As shown, in this embodiment, a medicine application cover 102 is provided at the bottom of the housing 101, and a flexible pad 103 is provided at the open end of the medicine application cover 102. The provision of the medicine application cover 102 protects the patient's eyes when applying medicine, and the provision of the flexible pad 103 improves the comfort of the tool when used.

[0056] like Figure 2 、 4 As shown in Figures 9 and 10, a detachable cover 401 is provided on the housing 101. Two sets of fixing frames 403 are provided at the bottom of the cover 401. The two sets of fixing frames 403 are arranged opposite each other. A medicine bottle 408 is provided between the two sets of fixing frames 403. The fixing frames 403 pass through the cover 401 and are slidably arranged inside the cover 401. A first return spring 402 is provided between the fixing frames 403 and the cover 401. Two sets of mounting grooves 404 are provided on the cover 401. Fixing buckles 405 are provided in the mounting grooves 404. The two sets of fixing buckles 405 are separated from each other. The pressing ends of the fixing buckles 405 protrude from one side of the cover 401. The locking ends of the fixing buckles 405 protrude from the bottom of the cover 401 and are locked in the locking grooves 305 provided on the inner side of the housing 101. Two sets of baffles 406 are provided inside the cover 401. A second return spring 407 is provided between the baffles 406 and the fixing buckles 405.

[0057] The medicine feeding tool simply fixes the medicine bottle 408 through the cooperation of the two sets of fixing frames 403 and the first return spring 402, and fixes the position of the cover 401 through the cooperation of the fixing buckle 405 and the card slot 305, thereby completing the stable installation of the medicine bottle 408. After use, the medicine feeding auxiliary tool can be removed by pressing the pressing ends of the two sets of fixing buckles 405 to disengage the buckle ends of the fixing buckles 405 from the card slot 305, and then separating the cover 401 from the housing 101. The medicine bottle 408 can be replaced by controlling the two sets of fixing frames 403 to open, making the medicine feeding auxiliary tool reusable.

[0058] Specific usage and beneficial effects of the present invention:

[0059] When the medicine application auxiliary tool is in use, the patient tilts his head back and holds the shell 101 with one hand, so that the body of the medicine bottle 408 is upright and the medicine tube 409 is placed directly above the eyeball. The patient uses the thumb to turn the control wheel 106 to rotate to drive the mounting plate 110 at one end of the mounting tube 105 to rotate, thereby causing the inclined block 107 on one side of the mounting plate 110 to move. By rotating the control wheel 106, the mounting plate 110 at one end of the mounting tube 105 is driven to rotate, thereby causing the inclined block 107 on one side of the mounting plate 110 to move. The inclined surface of the inclined block 107 pushes the first extrusion plate 203 to move and squeeze the medicine bottle 408, thereby squeezing the liquid medicine in the medicine bottle 408 to be squeezed out for eye medication. The fixed column 504 can be locked into different gear holes 108 by rotating the gear adjustment knob 502 to adjust the distance between the blocking rod 505 and the limit plate 109, thereby adjusting the rotation angle of the mounting cylinder 105, thereby adjusting the movement distance of the first extrusion plate 203, and adjusting the amount of medicine squeezed out each time in stages. The medicine application is convenient and fast, and effectively prevents elderly patients from squeezing out too little or too much medicine due to uncontrolled hand force, thereby improving the efficiency of medicine application for elderly patients.

[0060] After use, the medicine-applying auxiliary tool can be used to disengage the buckle end of the fixing buckle 405 from the card slot 305 by pressing the pressing end of the two sets of fixing buckles 405, and then the cover body 401 can be separated from the shell 101 to take out the medicine bottle 408, and then the two sets of fixing frames 403 can be controlled to open to replace the medicine bottle 408, so that the medicine-applying auxiliary tool can be used multiple times. After replacing medicine bottles 408 of different sizes, the squeezing block 205 can be driven to move on one side of the first squeezing plate 203 by rotating the threaded knob 208 until it contacts the outer wall of the medicine bottle 408, thereby avoiding changes in the size of the medicine bottle 408 resulting in an uncontrollable amount of medicine dripping, thereby improving the practicality of the medicine-applying auxiliary tool.

[0061] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
