Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and particularly relates to a pneumatic adsorption type corneal bandage mirror auxiliary wearing lachrymal gland speculum. BACKGROUND

[0002] BCL (Bandage Contact Lens), also known as a corneal bandage mirror, is a medical device used in ophthalmology treatment, mainly used for covering the corneal surface to provide protection and treatment, commonly used for treating the recovery period after corneal or corneal surgery, such as corneal transplantation, corneal ulcer, severe dry eye, etc., which helps to protect the cornea, reduce external irritation, and promote wound healing. The corneal bandage mirror is made of medical silicone or other biocompatible materials. Wearing a corneal bandage mirror for auxiliary treatment is more helpful to promote the recovery of corneal epithelium, relieve clinical symptoms, enhance tear film stability, and reduce the impact on the ocular surface environment. The main point is that the corneal bandage mirror is made of silicone hydrogel material, which has high oxygen permeability, elasticity and softness, and can be tightly attached to the cornea. After the corneal bandage mirror covers the cornea, it can isolate the contact and friction between the eyelid and the postoperative corneal epithelial defect area, avoid the stimulation of the corneal surface by the suture of the corneal limbus, protect the cornea, reduce the shedding of the newly formed corneal epithelium caused by the friction between the corneal epithelium and the eyelid during blinking, thereby reducing eye irritation, eliminating edema, relieving pain, reducing the risk of infection and recurrence, reducing postoperative eye discomfort of patients, promoting corneal healing, and prolonging tear film break-up time.

[0003] In the prior art, the upper and lower eyelids are opened by hand or lachrymal gland speculum, which not only has a small opening range, but also easily causes skin redness and swelling, and when the corneal bandage mirror is worn again, it is easy to contact the eyelashes and cause ocular surface inflammation. Moreover, when the patient independently wears the corneal bandage mirror, if the eyelids are opened by hand, the patient only has one hand to wear the corneal bandage mirror, making it difficult to wear the corneal bandage mirror.

DETAILED DESCRIPTION

[0039] The specific embodiments of the present application will be described in detail below. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0040] In the present application, unless otherwise stated, the orientation words such as "up, down" generally refer to the orientation in the assembled and used state. "In, out" refers to the inside and outside relative to the outline of each component.

[0041] As shown in the accompanying Figure 1 , the accompanying Figure 2 , the present application discloses a kind of corneal bandage mirror auxiliary wearing gas suction type open eyelid speculum, including adsorption sheet 100, mounting shell 3, driving mechanism 200, control unit 1 and integrated tube 2.

[0042] Adsorption sheet 100 has two, two adsorption sheets 100 are called first adsorption sheet 7 and second adsorption sheet 6 respectively, and first adsorption sheet 7 and second adsorption sheet 6 are used to adsorb upper and lower eyelids respectively. There are several air holes 8 in adsorption sheet 100, and control unit 1 is used to generate negative pressure in air hole 8, so that adsorption sheet 100 can be adsorbed on the eyelid. The adsorption of adsorption sheet 100 is directly proportional to the degree of negative pressure in air hole 8.

[0043] First adsorption sheet 7 and second adsorption sheet 6 are rotatably mounted on mounting shell 3, i.e. mounting shell 3 provides the mounting platform of first adsorption sheet 7 and second adsorption sheet 6 to improve the stability during the process of opening eyelid. Driving mechanism 200 is used to drive first adsorption sheet 7 and second adsorption sheet 6 to rotate in opposite directions to open upper and lower eyelids, and the driving force of driving mechanism 200 is provided by control unit 1. As shown in the accompanying Figure 3As shown, the integrated pipe 2 includes a first connecting pipe 10 connected between the control unit 1 and the first adsorption sheet 7, and a second connecting pipe 11 connected between the control unit 1 and the second adsorption sheet 6, and the integrated pipe 2 is used to integrate and converge the first connecting pipe 10 and the second connecting pipe 11, so as to avoid the pipe being scattered.

[0044] In combination with the accompanying drawings Figure 4 , the accompanying drawings Figure 5 As shown, the first adsorption sheet 7 and the second adsorption sheet 6 are attached to the upper and lower eyelids, the patient holds and operates the control unit 1, and generates negative pressure in the air holes 8 of the first adsorption sheet 7 and the second adsorption sheet 6 through the first connecting pipe 10 and the second connecting pipe 11, so that the first adsorption sheet 7 and the second adsorption sheet 6 can be adsorbed in the upper and lower eyelids, respectively, and then the control unit 1 provides driving force to the driving mechanism 200, and drives the first adsorption sheet 7 and the second adsorption sheet 6 to rotate in opposite directions, so as to open the upper and lower eyelids and facilitate wearing of the corneal bandage mirror. The control unit 1 is provided to facilitate manual control and operation of the patient. The adsorption sheet 100 is adsorbed on the eyelid in a negative pressure adsorption manner, which can not only avoid contact between the adsorption sheet 100 and the eyelashes, thereby reducing the probability of inflammation of the ocular surface, but also does not require the patient to continuously operate, thereby freeing the hands of the patient and facilitating the patient to wear the corneal bandage mirror with both hands.

[0045] Further, the first rotating wheel 21 and the second rotating wheel 19 are rotatably installed on the mounting shell 3, the first connecting rod 4 is fixedly connected between the first rotating wheel 21 and the first adsorption sheet 7, and the second connecting rod 5 is fixedly connected between the second rotating wheel 19 and the second adsorption sheet 6. The rotating wheels and the connecting rods are provided to facilitate installation between the adsorption sheet 100 and the mounting shell 3. In addition, the connecting rods can also make the mounting shell 3 as far as possible from the eyes of the patient and even from the face when the adsorption sheet 100 is adsorbed on the eyelid, so as to avoid interference of the mounting shell 3 with wearing of the corneal bandage mirror by the patient.

[0046] In some embodiments, the mounting shell 3 has a cavity 13, the cavity 13 has a first limiting groove 17 for the first connecting rod 4 to pass through and a second limiting groove 18 for the second connecting rod 5 to pass through. The first rotating wheel 21 and the second rotating wheel 19 are rotatably installed in the cavity 13, and the first adsorption sheet 7 and the second adsorption sheet 6 are located outside the cavity 13. The cavity 13 is provided in the mounting shell 3 to accommodate the first rotating wheel 21 and the second rotating wheel 19, so as to hide the structure, improve the appearance, and protect the structure of the rotating wheels.

[0047] The first limiting groove 17 and the second limiting groove 18 are set to avoid the first connecting rod 4 and the second connecting rod 5 on the one hand, and to limit the rotation range of the first connecting rod 4 and the second connecting rod 5 on the other hand, thereby limiting the rotation range of the first adsorption sheet 7 and the second adsorption sheet 6, and finally limiting the maximum range of the first adsorption sheet 7 and the second adsorption sheet 6 in opening the eyelid, so as to avoid excessive opening of the eyelid and causing discomfort to the patient's eye.

[0048] In some embodiments, a rotation reset member 27 is provided between the first rotating wheel 21 and the mounting housing 3, and between the second rotating wheel 19 and the mounting housing 3. (See attached...) Figure 6 As shown, this embodiment will be specifically described using the first rotating wheel 21 as an example.

[0049] In this embodiment, the first rotating wheel 21 is rotatably mounted on the inner wall of the cavity 13 via a support shaft 26, and a rotation reset member 27 is connected between the inner wall of the cavity 13 and the first rotating wheel 21. When the driving mechanism 200 no longer applies driving force to the first rotating wheel 21, the first rotating wheel 21 rotates and resets under the action of the rotation reset member 27. Specifically, the first rotating wheel 21 rotates counterclockwise under the action of the driving mechanism 200, causing the first suction sheet 7 to rotate upward, thereby opening the upper eyelid upward. When the driving mechanism 200 no longer applies driving force to the first rotating wheel 21, the first rotating wheel 21 rotates and resets clockwise under the action of the rotation reset member 27.

[0050] Similarly, the second rotating wheel 19 is rotatably mounted on the inner wall of the cavity 13 via the support shaft 26, and a rotation reset member 27 is connected between the inner wall of the cavity 13 and the second rotating wheel 19. Under the action of the drive mechanism 200, the second rotating wheel 19 rotates clockwise, causing the second suction sheet 6 to rotate downward, thereby pulling the lower eyelid downward. When the drive mechanism 200 no longer applies driving force to the second rotating wheel 19, the second rotating wheel 19 rotates counterclockwise to reset under the action of the rotation reset member 27.

[0051] In some embodiments, in conjunction with the appendix Figure 7 Appendix Figure 8 The first rotating wheel 21, the first connecting rod 4, and the first adsorption plate 7 are integrally formed. The first rotating wheel 21, the first connecting rod 4, and the first adsorption plate 7 have a first air guiding channel 23a. One end of the first air guiding channel 23a communicates with the air hole 8 on the first adsorption plate 7, and the other end communicates with the first connecting pipe 10. The second rotating wheel 19, the second connecting rod 5, and the second adsorption plate 6 are integrally formed. The second rotating wheel 19, the second connecting rod 5, and the second adsorption plate 6 have a second air guiding channel 23b. One end of the second air guiding channel 23b communicates with the air hole 8 on the second adsorption plate 6, and the other end communicates with the second connecting pipe 11.

[0052] It should be noted that in the appendix Figure 7 Appendix Figure 8In the embodiment, the labels in the brackets correspond to the second rotating wheel 19, the second connecting rod 5, the second adsorption piece 6, and the second air guide channel 23b.

[0053] In the embodiment, the first rotating wheel 21, the first connecting rod 4, and the first adsorption piece 7 are integrally formed, and the second rotating wheel 19, the second connecting rod 5, and the second adsorption piece 6 are integrally formed, so that the first air guide channel 23a and the second air guide channel 23b can be directly reserved in the production stage, without subsequent processing. In addition, the built-in air guide channel can also reduce the use of pipelines and save production costs.

[0054] Further, in combination with the accompanying drawings Figure 2 , the accompanying drawings Figure 5 , and the accompanying drawings Figure 6 , the first fixed wheel 22 and the second fixed wheel 20 are fixedly connected to the mounting shell 3, the first fixed wheel 22 is coaxial with the first rotating wheel 21 and is in rotational fitting connection, and the first connecting pipe 10 is fixedly connected to the first fixed wheel 22; the second fixed wheel 20 is coaxial with the second rotating wheel 19 and is in rotational fitting connection, and the second connecting pipe 11 is fixedly connected to the second fixed wheel 20. Among them, the first fixed wheel 22 and the second fixed wheel 20 each have a communication hole 24 that is open through in the axial direction, the communication hole 24 in the first fixed wheel 22 communicates the first connecting pipe 10 and the first air guide channel 23a, and the communication hole 24 in the second fixed wheel 20 communicates the second connecting pipe 11 and the second air guide channel 23b.

[0055] It should be noted that the accompanying drawings Figure 6 specifically show the connection structure of the first rotating wheel 21, the first fixed wheel 22, and the first connecting pipe 10.

[0056] Since the first rotating wheel 21 and the second rotating wheel 19 will rotate in the process of adsorbing and supporting the eyelid by the first adsorption piece 7 and the second adsorption piece 6, if the first connecting pipe 10 and the second connecting pipe 11 are directly connected to the first rotating wheel 21 and the second rotating wheel 19, the first connecting pipe 10 and the second connecting pipe 11 will be twisted with the rotation of the first rotating wheel 21 and the second rotating wheel 19, affecting the gas flow in the pipeline and the negative pressure adsorption effect of the air holes 8 on the adsorption piece 100, and the adsorption piece 100 is easy to fall off from the eyelid.

[0057] In this embodiment, the first fixed wheel 22 and the second fixed wheel 20 are fixed to the inner wall of the mounting shell 3 using fasteners 28 such as bolts. The first connecting pipe 10 is connected to the first fixed wheel 22, and the second connecting pipe 11 is connected to the second fixed wheel 20, preventing the first connecting pipe 10 and the second connecting pipe 11 from twisting with the first rotating wheel 21 and the second rotating wheel 19. It should be noted that the installation position of the fasteners 28 needs to avoid the first connecting pipe 10 and the second connecting pipe 11. In addition, the first fixed wheel 22 and the first rotating wheel 21, as well as the second fixed wheel 20 and the second rotating wheel 19, are all connected by sealed bearings 25 for rotational engagement, achieving the requirement of relative rotation while ensuring airtightness.

[0058] In some embodiments, a movable space 14 is provided in the mounting housing 3, and the drive mechanism 200 includes a piston 15 and a push rod 16. The piston 15 is slidably disposed within the movable space 14 and is driven to slide by the control unit 1, while the push rod 16 is fixed to the piston 15 and slides together with the piston 15. The first rotating wheel 21 and the second rotating wheel 19 rotate under the action of the push rod 16. An extension 12 is provided inside the mounting housing 3, and the movable space 14 is formed within the extension 12 to ensure that the movable space 14 has sufficient length for the piston 15 to slide.

[0059] Specifically, the first rotating wheel 21 and the second rotating wheel 19 rotate in opposite directions by the linear sliding of the push rod 16. In this embodiment, combined with the attached... Figure 2 Appendix Figure 5 The push rod 16 slides from left to right, passing between the first rotating wheel 21 and the second rotating wheel 19 in a frictional contact manner, and pushes the first rotating wheel 21 to rotate counterclockwise and pushes the second rotating wheel 19 to rotate clockwise.

[0060] In other embodiments, teeth may be machined on the push rod 16, and teeth may also be machined on the circumferential surfaces of the first rotating wheel 21 and the second rotating wheel 19, so that the push rod 16 and the first rotating wheel 21 and the second rotating wheel 19 can be driven by meshing transmission to realize the power transmission of the push rod 16 sliding to drive the first rotating wheel 21 and the second rotating wheel 19 to rotate.

[0061] Furthermore, the integrated pipe 2 also includes a third connecting pipe 9, one end of which is connected to the control unit 1, and the other end is connected to the moving space 14. The control unit 1 pumps air into or out of the moving space 14 through the third connecting pipe 9 to move the piston 15. In addition, the third connecting pipe 9 is constricted within the integrated pipe 2, improving the degree of pipe integration and constriction.

[0062] Furthermore, in conjunction with the appendix Figure 9 Appendix Figure 10, the control unit 1 comprises an air pump 29, the air pump 29 is provided with a first interface 30 and a second interface 31. The first interface 30 of the air pump 29 is in communication with the first connecting pipe 10 and the second connecting pipe 11, and the second interface 31 of the air pump 29 is in communication with the third connecting pipe 9. Specifically, the first interface 30 is provided with two, and the second interface 31 is provided with one.

[0063] When the air pump 29 is running forward, the first interface 30 is the air inlet and the second interface 31 is the air outlet, at this time the air pump 29 pumps air from the first connecting pipe 10 and the second connecting pipe 11 to the third connecting pipe 9, generating negative pressure in the air hole 8 in the adsorption piece 100 while pushing the piston 15 to move, so as to complete the adsorption of the adsorption piece 100 to the eyelid while opening the eyelid. When the air pump 29 is running reversely, the first interface 30 is the air outlet and the second interface 31 is the air inlet, at this time the air pump 29 pumps air from the third connecting pipe 9 to the first connecting pipe 10 and the second connecting pipe 11, increasing the air pressure in the air hole 8 while making the piston 15 slide back, so as to make the adsorption piece 100 fall off from the eyelid and rotate to reset. When the air pump 29 is not running, the first interface 30 is cut off from the second interface 31, when the adsorption piece 100 is fully opened to the eyelid, the air pump 29 is stopped running by the control unit 1 and the first interface 30 is cut off from the second interface 31, at this time the air hole 8 is kept in a negative pressure state and the first adsorption piece 7 and the second adsorption piece 6 are kept in an open state to the eyelid, so the patient does not need to operate the control unit 1 again, thereby freeing the hands and facilitating the patient to wear the corneal bandage mirror by himself.

[0064] Further, the sliding process of the piston 15 includes a pre-tightening stage and a contact stage, in the pre-tightening stage the push rod 16 is not in contact with the first rotating wheel 21 and the second rotating wheel 19, and in the contact stage the push rod 16 is in contact with the first rotating wheel 21 and the second rotating wheel 19. In the pre-tightening stage, the sliding distance of the piston 15 is greater than zero.

[0065] Specifically, in the pre-tightening stage, when the control unit 1 controls the air pump 29 to run forward, the air hole 8 in the first adsorption piece 7 and the second adsorption piece 6 generates negative pressure and is adsorbed on the eyelid, and at the same time the piston 15 and the push rod 16 slide, but the push rod 16 is not in contact with the first rotating wheel 21 and the second rotating wheel 19, so as to avoid the first adsorption piece 7 and the second adsorption piece 6 starting to open the eyelid when the first adsorption piece 7 and the second adsorption piece 6 are not fully adsorbed on the eyelid.

[0066] When entering the contact stage, the first adsorption piece 7 and the second adsorption piece 6 have a certain adsorption effect on the eyelid, at this time the push rod 16 is in contact with the first rotating wheel 21 and the second rotating wheel 19, so as to drive the first adsorption piece 7 and the second adsorption piece 6 to open the eyelid, thereby avoiding the first adsorption piece 7 and the second adsorption piece 6 falling off from the eyelid.

[0067] It should be noted that the negative pressure in the air hole 8 gradually increases during the process of the first adsorption piece 7 and the second adsorption piece 6 opening the eyelid, that is, the adsorption strength of the first adsorption piece 7 and the second adsorption piece 6 on the eyelid gradually increases. Specifically, during the process of opening the eyelid, the eyelid has a closing reverse trend, and the greater the opening degree of the eyelid, the stronger the closing reverse trend, and at this time, the gradual increase of the adsorption strength of the first adsorption piece 7 and the second adsorption piece 6 on the eyelid can also avoid the situation that the adsorption piece 100 falls off from the eyelid.

[0068] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the specific details in the above embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0069] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present application will not further describe various possible combination manners.

[0070] In addition, various different embodiments of the present application can also be combined in any manner, as long as it does not deviate from the idea of the present application, and it should also be considered as disclosed by the present application.
