Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, to an eye dropper for ophthalmic care. Background Technology

[0002] Eye drops are medications used to relieve eye fatigue or treat eye diseases. To facilitate use, the bottles are typically flexible. The drops are dispensed by squeezing the bottle and then aimed at the eye. However, the eye tends to close, making it difficult to get the drops into the eye. Currently, the usual method involves holding the bottle with one hand and using the other to open the eyelid, but this makes it difficult to control the amount of medication dispensed.

[0003] To address the difficulty in controlling the amount of medication administered, the medication is usually dripped through a syringe. The amount of medication is controlled by the pressure applied to the syringe. However, this requires squeezing the syringe with one hand and holding the eyelid open with the other. This necessitates observing the dripping process and constantly monitoring the amount of medication, making the operation quite complex. Additionally, it is difficult to aim the syringe precisely at the eye, which can easily lead to errors.

[0004] Therefore, there is a need for an eye dropper for ophthalmic care to solve the above problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an eye dropper for ophthalmic care, comprising: a main cylinder having a medicine chamber and a control chamber, with an outlet at the lower end of the main cylinder for discharging medicine from the medicine chamber; two pressing handles hinged to the main cylinder; a spreading block fixedly disposed at one end of the pressing handle, located below the outlet, for spreading the eyelid; a piston slidably disposed within the main cylinder for squeezing out medicine from the medicine chamber; a sliding block slidably disposed within the main cylinder for driving the piston; a hinge rod hinged at one end to the sliding block and at the other end to the pressing handle, the angle between the hinge rod and the pressing handle being acute; and a control assembly for controlling the drip volume. The control assembly includes: a sliding retaining ring slidably disposed within the control chamber for limiting the piston; and a screw rotatably disposed on the main cylinder, passing through the sliding retaining ring and threadedly connected to it.

[0007] The eyelids are opened by a combination of a pressing handle and a spreading block, preventing instillation failure due to eye closure. A piston mechanism forces the medication through the dispensing nozzle, and the dispensing volume is adjusted by changing the pressing distance of the piston. A sliding retaining ring and a screw control the pressing distance of the piston by rotating the screw. A sliding block and a hinge rod, by pushing the two pressing handles, move the sliding block via the hinge rod, which in turn moves the piston rod, allowing the medication to be instilled while the eyelids are open. This eliminates the need for simultaneous two-handed operation, reducing inconvenience.

[0008] Furthermore, a transmission groove extending along the axis of the main cylinder is provided on the main cylinder body, the piston component has a sliding part that is slidably disposed in the transmission groove, the sliding block is slidably disposed in the transmission groove and located below the sliding part, and a first spring is connected between the sliding block and the sliding part.

[0009] The first spring is designed so that when the slider moves downward, it stretches and deforms. The sliding part does not move synchronously with the slider. When the spring is not under force, the slider moves upward and compresses the spring. At this time, the spring does not deform and directly pushes the sliding part.

[0010] Furthermore, the main cylinder is hinged with a buckle for limiting the sliding part, the buckle has a limiting part, and the sliding part has a slot for the limiting part to be inserted.

[0011] The sliding part is limited by the locking mechanism, so that it will not move when the eyelid is fully opened by the opening block. This avoids the problem of the liquid outlet starting to dispense liquid before the eyelid is fully opened, which would otherwise lead to waste of the medicine.

[0012] Furthermore, the buckle also has an abutment portion for contacting the pressing handle, the abutment portion and the limiting portion being located on opposite sides of the buckle hinge axis, and a return spring being provided between the abutment portion and the main cylinder.

[0013] The abutting part is designed so that when the two pressing handles work together to fully open the eyelids, the pressing handles contact the connecting part and push the abutting part, causing the buckle to deflect around the hinge axis, thereby causing the limiting part of the buckle to disengage from the slot and no longer limit the sliding part.

[0014] Furthermore, the piston component also includes a piston portion slidably disposed within the medicine chamber and a connecting portion located within the control chamber. The connecting portion is used to connect the sliding portion and the piston portion. The sliding portion has a limiting end located within the control chamber. A sliding retaining ring is located below the limiting end, and the sliding retaining ring abuts against the limiting end to limit the piston component.

[0015] The piston section, when sliding within the medicine chamber, pushes the medicine to drip from the outlet. A limiting end, when in contact with the sliding retaining ring, restricts the piston section's movement.

[0016] Furthermore, a second spring is provided between the sliding block and the main cylinder, with both ends of the second spring fixedly connected to the sliding component and the main cylinder, respectively.

[0017] The second spring ensures that the slider returns to its initial state after the dripping is complete.

[0018] Furthermore, the limiting part is provided with an inclined surface, so that the limiting part limits the piston in one direction.

[0019] By setting an inclined surface, when the sliding part moves upward, it can push the limiting part to deflect the buckle. The sliding part continues to move upward, and when the limiting part is in the slot position, it is locked into the slot, which can limit the downward movement of the sliding part.

[0020] Furthermore, the sliding retaining ring is provided with a connecting lug that extends out of the control cavity, the screw passes through the connecting lug and is threadedly connected to the connecting lug, and the main cylinder is provided with a slot for the connecting lug to pass through.

[0021] The connecting lugs and slots allow the screw to be kept at a certain distance from the side wall of the main cylinder, making it easier to rotate the screw.

[0022] Furthermore, sliding damping is provided between the sliding part and the transmission groove.

[0023] By setting sliding damping, the sliding part is prevented from sliding too quickly, which would cause the medicine to flow out rapidly.

[0024] Furthermore, the expansion block is slidably disposed at one end of the pressing handle, and an elastic element is disposed between the expansion block and the pressing handle.

[0025] By incorporating elastic elements, excessive force is avoided to prevent discomfort when the expansion block is opened.

[0026] The beneficial effects of this application are as follows:

[0027] 1. The eyelid is opened by the combination of the pressing handle and the opening block, which prevents the eye from closing and thus prevents the medicine from failing to be dripped. The piston can be pressed to squeeze the medicine out of the outlet for dripping. The amount of medicine dispensed can be adjusted by adjusting the pressing distance of the piston.

[0028] 2. By adjusting the position of the sliding retaining ring and the screw by rotating the screw, the pressing distance of the piston can be controlled, thereby precisely controlling the amount of medicine dripped.

[0029] 3. By using the sliding block and hinge rod, pushing the two pressing handles causes the sliding block to move via the hinge rod, which in turn moves the piston rod, allowing the eyelids to be opened to administer the medication. This avoids the inconvenience of having to operate with both hands simultaneously.

[0030] 4. The sliding part is limited by the set buckle. When the eyelid is fully opened by the opening block, the sliding part will not move, which avoids the problem of the liquid outlet starting to dispense liquid before the eyelid is opened, thus avoiding the waste of medicine.

[0045] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Reference Figure 1-5An eye dropper for ophthalmic care includes: a main body 100, a pressing handle 101, a spreading block 102, a piston 103, a sliding block 104, a hinge rod 105, a sliding retaining ring 106, and a screw 107. The main body 100 has a medicine chamber 108, and a liquid outlet 109 communicating with the medicine chamber 108 is located at the lower end of the main body 100. The piston 103 includes a piston portion 110 slidably disposed within the medicine chamber 108, thereby displacing the medicine in the medicine chamber 108 from the liquid outlet 109 when the piston 103 moves. Two pressing handles 101 are provided, hinged to the main body rod, and each pressing handle 101 has a gripping portion for finger holding. One end of the pressing handle 101 is connected to a spreading block 102 located below the liquid outlet 109. The spreading block 102 is slidably disposed at one end of the pressing handle 101, and an elastic element 111 is disposed between the spreading block 102 and the pressing handle. When both pressing handles 101 are pressed, the eyelids are opened by the spreading blocks 102 on both sides. At the same time, when the opening force is too great, the spreading block 102 and the pressing handle 101 slide relative to each other, and the elastic element 111 deforms to avoid excessive opening force. The elastic element 111 can be a spring.

[0047] In one embodiment, the main cylinder 100 has a transmission groove 112 extending along the axis of the main cylinder 100, and a sliding block 104 is slidably connected within the transmission groove 112. The piston component 103 also includes a sliding portion 113 slidably disposed within the transmission groove 112, and a sliding damping 114 is provided between the sliding portion 113 and the transmission groove 112. The sliding block 104 is slidably disposed within the transmission groove 112 and located below the sliding portion 113. A first spring 115 is connected between the sliding block 104 and the sliding portion 113, and both ends of the first spring 115 are fixedly connected to the sliding block 104 and the sliding portion 113, respectively. A second spring 125 is provided between the sliding block 104 and the main cylinder 100, and both ends of the second spring 125 are fixedly connected to the sliding block 104 and the main cylinder 100, respectively. A hinge rod 105 is hinged to the sliding block 104, and the other end of the hinge rod 105 is hinged to the pressing handle 101. When the push handle 101 is pushed, causing the two opening blocks 102 to move in opposite directions and open the eyelids, the hinge rod 105 can drive the sliding block 104 to slide downward in the transmission groove 112. Then, the first spring 115 drives the sliding part 113 to move, causing the piston 103 to move downward and push the medicine in the medicine chamber 108 out of the outlet 109.

[0048] In one embodiment, a latch 116 for limiting the sliding portion 113 is hinged to the main cylinder 100. The latch 116 has a limiting portion 117, and the sliding portion 113 has a slot 118 for the limiting portion 117 to be inserted into. The latch 116 also has an abutment portion 119 for contacting the pressing handle 101. The abutment portion 119 and the limiting portion 117 are located on opposite sides of the hinge axis of the latch 116. A return spring 120 is provided between the abutment portion 119 and the main cylinder 100. When the two spreading blocks 102 are closest to each other, the sliding block 104 is at the uppermost position. At this time, the limiting portion 117 is inserted into the slot 118, preventing the sliding portion 113 from moving downward. When the two pressing handles 101 are pressed, causing the two sliding blocks 104 to move to their furthest positions, the pressing handles 101 abut against the abutment portion 119, thereby pushing the latch 116 to deflect around the hinge axis. This causes the limiting portion 117 to disengage from the slot 118, no longer limiting the sliding portion 113. The limiting portion 117 has an inclined surface, allowing it to unidirectionally limit the piston 103. When the sliding portion 113 moves upward, it can push the limiting portion 117 to deflect the latch 116. As the sliding portion 113 continues to move upward, when the limiting portion 117 is in the slot 118, it engages with the slot 118, thus limiting the downward movement of the sliding portion 113.

[0049] In one embodiment, a control cavity 121 is provided inside the main cylinder 100, located outside the medicine cavity 108, and communicating with the transmission groove 112. The sliding portion 113 has a limiting end 122 located within the control cavity 121. The piston component 103 further includes a connecting portion 123 for connecting the sliding portion 113 and the piston portion 110, the connecting portion 123 being located within the control cavity 121. A sliding retaining ring 106 is slidably disposed within the control cavity 121 and located below the limiting end 122. When the limiting end 122 abuts against the sliding retaining ring 106, the sliding retaining ring 106 limits the limiting end 122.

[0050] A screw 107 is rotatably mounted on the main cylinder 100, and a connecting lug 124 extending out of the control cavity 121 is provided on the moving retaining ring. The screw 107 passes through the connecting lug 124 and is threadedly connected to the connecting lug 124. A slot is provided on the main cylinder 100 for the connecting lug 124 to pass through.

[0051] Usage instructions or work process:

[0052] 1. The medicine chamber 108 contains the medicine. When it is necessary to administer the instillation, the outlet 109 is aligned with the eye, and the two opening blocks 102 are brought into contact with the eyelid. The two pressing handles 101 are pressed, causing the two opening blocks 102 to move in opposite directions, opening the eyelid. At this time, the sliding block 104 is moved by the hinge rod 105. Since the limiting part 117 is embedded in the slot 118, it in turn causes the first spring 115 to stretch. After the eyelid is opened, the pressing handle 101 contacts the abutment part 119, causing the limiting part 117 to disengage from the slot 118. Under the action of the first spring 115, the sliding part 113 moves, which in turn drives the piston 103 to move, pushing the medicine out of the outlet 109 for instillation. When the limiting end 122 moves to contact the sliding retaining ring 106, it stops moving, and the instillation stops.

[0053] 2. When the dripping volume needs to be adjusted, the screw 107 is rotated, which drives the sliding retaining ring 106 to move, adjusting the position of the retaining ring and thus the dripping volume. After dripping is complete, the two pressing handles 101 are no longer pressed. Under the action of the second spring 125, the sliding block 104 returns to its initial position, thereby pushing the sliding part 113 back to its initial position, which in turn drives the piston 103 to move to its initial position. When the sliding part 113 moves upward, the limiting part 117 is re-embedded into the slot 118 under the action of the inclined surface.

[0054] 3. When it is necessary to add medicine into the medicine chamber 108, the sliding retaining ring 106 is moved to the lowest position by rotating the screw 107. The piston 103 can also move to the lowest position, so that the lower end of the main cylinder 100 is inserted into the medicine. Then, when the piston 103 is reset, the medicine can be sucked into the medicine chamber 108.
