Description

Ophthalmic dropping liquid device accurate in positioning

Technical Field

The invention relates to a medical instrument, in particular to an ophthalmic dropping device with accurate positioning.

Background

The eye is the most important organ in human sense, and about 80% of the knowledge in the brain is acquired by the eye. The eye diseases which are clinically common at present include conjunctivitis, xerophthalmia, keratitis and senile eye diseases such as senile cataract, glaucoma and vitreous opacity besides external physical or chemical injury. Due to the particularity of the ocular organs, for some ocular diseases, the administration of the eye drops is largely dependent on the eye drops in addition to the surgery. For example, for bacterial conjunctivitis, antibiotic eye drops such as quinolone levofloxacin, ofloxacin, tobramycin, etc. are generally used; for viral conjunctivitis, ganciclovir ophthalmic gel is generally used; in the case of allergic conjunctivitis, antiallergic eye drops such as patarol, emetidine, etaxepine, etc. are generally used. In general, eye drops for eye use are not particularly easy to be instilled accurately in the eye when a patient self-instills the eye drops, and particularly, the relatively simple action becomes very complicated for the aged group whose action coordination and vision have deteriorated.

In some disclosures, manufacturers have developed devices to assist in eye drops. For example, chinese patent application publication CN110072502A discloses an eye drop assist device, which aims to administer eye drops to eyes of a patient in a proper amount and accurately. The present invention is directed to an eye drop container including a container body that contains eye drops, a discharge portion that discharges the eye drops from a discharge hole, and a support portion that is provided between the container body and the discharge portion and supports the discharge portion so as to be movable toward the container body, wherein the eye drop container is configured to deliver the eye drops to the discharge portion by moving the discharge portion in a direction toward the container body by an operation of an administrator, wherein the eye drop assistor includes an assistor body that is assembled to the container body, and the assistor body includes a finger-engaging portion that fixes positions of two fingers of the administrator who sandwiches the assistor body so as to support the eye drop assistor. However, the main purpose of its structural design is to enable the patient to receive the drip with the patient facing forwards. It is well known that the blink response is an unconditional neural reflex, simply an instinct of the human body, and is uncontrolled. Thus, the proposal can only solve the problem of the posture of the patient when the patient applies the medicine, and cannot solve the problem of instillation failure caused by blinking of eyes when the eyes feel liquid drops. This is the main reason why the efficiency of eye drop instillation is not high without the assistance of other people.

Thus, the prior art still has the defects and needs to be improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings of the embodiments of the present disclosure.

It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

As shown in fig. 1 and 2, an aspect of the embodiment of the present invention provides an accurately positioned ophthalmic dropping device, which is combined (inserted or adhered) with an eye drop bottle 1 containing an eye drop 13 to assist in dropping the eye drop 13, wherein the eye drop bottle 1 exemplarily shows a structure of a commercially available general eye drop bottle, which includes a bottle body 11 and a dropping head 12, and the eye drop 11 is accommodated in the bottle body 11 and can be dropped through the dropping head 12. In a typical instillation procedure, the patient is required to hold and squeeze the flat body 11 so that the eye drop 13 can be instilled into the eye of the patient by the instillation head 12. However, this process is difficult for the elderly with uncoordinated hands and feet or people with impaired vision, and often requires the assistance of medical workers or family members. In the device provided by the present invention, as shown in the figure, the device may include a device body 2, the device body 2 includes a holding portion 21 and an anastomosis member 22 combined with the holding portion 21, the holding portion 21 is configured to be grasped by at least two fingers of the patient and has a hollow portion (not labeled in the figure) for the eye medicine bottle 1 to pass through, it is noted that the bottle body 11 of the eye medicine bottle 1 is still partially exposed from the holding portion 21, so that the other hand of the patient can still perform instillation by squeezing the bottle body 11. The purpose of the anastomosis member 22 is primarily to achieve initial positioning by anastomosis about the patient's orbit. In order to improve the comfort, the anastomosis member 22 may be made of a flexible material (e.g. medical silica gel), and is configured as an inverted funnel shape having a smaller top opening (not shown) and a larger bottom opening (not shown), and an angle adjusting mechanism 3 for adjusting the inclination angle of the eyedrop bottle 1 relative to the central line (central axis) thereof is disposed inside the anastomosis member, near the smaller top opening, the eyedrop bottle 1 has one end of the drip-injecting head 12 passing through the holding portion 21 and being clamped on the angle adjusting mechanism 3, and the drip-injecting head 12 at least partially extends into the anastomosis member 22. It can be seen that, in this embodiment, when the patient performs the infusion, the anastomosis member 22 is firstly buckled on the eye socket to complete the initial positioning, and then the inclination angle of the infusion head 12 in the anastomosis member 22 is adjusted by applying a force to the bottle body 11, so as to reduce the error caused by the shaking of the hand at the moment of the infusion.

As can be seen from the above embodiments, the stapling element 22 only serves for preliminary positioning, while the angle adjustment mechanism 3 serves for increasing the accuracy. For the specific construction of the angle adjustment means 3, it is conceivable to realize it directly from a deformable element attached to the anastomosis member, for example an elastic sheet of a clip drip-point. It is also contemplated that the accuracy may be further improved, and specifically, as shown in fig. 2, the angle adjusting mechanism 3 may include a first bowl-shaped connecting member 31 assembled and constrained in the engaging member 22, and a second bowl-shaped member 32 slidably assembled in the first bowl-shaped member 31, wherein a body constraining portion 33 for inserting the eyedropper 1 is extended from the second bowl-shaped member 32. In some embodiments, the body restraint portion 33 may be substantially integral with the second bowl 32, and the body restraint portion 33 is also preferably made of a flexible material, but unlike the purpose of comfort enhancement of the anastomosis member 22, the body restraint portion 33 requires strength to provide a clamping fixation of the eyedropper 1. That is, in fact, whether or not the body restraint portion 33 is integrally formed with the second bowl-shaped member 32, the body restraint portion 33 is made of a material different from that of the engaging member 22 but required to have a certain deformability, and in the present invention, PP, PE, PET, COC, or COP (cyclic olefin polymer) is preferable.

Further, considering that the angle adjustment mechanism 3 needs to be adjustable within a certain range, the outer edge surface of the bottle body restriction portion 33 needs to have a certain amount of clearance rather than being tightly fitted to the quality inspection of the anastomosis member 22. Therefore, as shown in fig. 2, it is preferable that the outer edge surface of the bottle body restraining portion 33 is an inclined surface so that the whole bottle body restraining portion 33 has a frustum shape. Thus, the patient can easily manipulate the bottle body 1 to incline it. In this case, it is preferable that a thin neck portion 34 is formed between the bottle body restraining portion 33 and the second bowl 32, and an expansion ring 23 for positioning the bottle body restraining portion 33 near a central axis (not labeled) when the bottle body restraining portion 33 is not subjected to an external force is provided in the thin neck portion 34. The expansion ring 23 is similar in structure to a sealing ring, but does not play a sealing role, and in the present invention, the elastic characteristic is mainly relied on, so that the bottle body restriction part 33 can deflect when external force is applied, and can dynamically return to the central shaft accessory when the external force disappears. Specifically, when an external force is applied to the eyedropper 1 to make it deviate from the central axis, the body restraint portion 33 is deflected around the expansion ring 23, and the second bowl 32 slides in the first bowl 31, so that the drip nozzle 12 of the eyedropper 1 deviates from the central axis by an angle a in the engaging member 22, as shown in fig. 5. In this embodiment of the invention, the angle a is typically in the range of 5 ° to 15 °, which in fact constitutes a fairly free angular adjustment, suitable for eye drop instillation in most settings.

In addition, as shown in fig. 3, since the angle adjusting mechanism 3 is required to adjust the eyedrop bottle 1 in the direction deviating from the central axis, the opening of the first bowl 31 may cause a blockage during the deflection, especially when the deflection angle is adjusted over a wide range. Therefore, in order to improve this problem, as shown in the drawing, the edge of the opening of the first bowl 31 near the side of the thin neck portion 34 is configured with a plurality of notches 3112 for facilitating the escape of the bottle body restraining portion 33.

Furthermore, in the above embodiments of the present invention, the angle adjusting mechanism 3 is exemplified to include the first bowl-shaped member 31 and the second bowl-shaped member 32, and it is conceivable that the first bowl-shaped member 31 is actually kept in a fixed position during the adjustment process, and has no relative slip with the second bowl-shaped member 2, i.e. a relatively firm combination, and may be generally an adhesive combination. However, in view of convenience of sterilization and cleaning, it is preferable that, as shown in fig. 2 and 3, the other side opening edge of the first bowl 31 is provided with a folded edge 311, and the inner side wall of the anastomosis member 22 is surrounded by a clamping platform 222 for the folded edge to be placed thereon. In fact, the locking platform 222 and the anastomosis member 22 can be integrally formed during the processing, i.e. they are made of a flexible material such as silicone rubber. The first bowl-shaped part 31 and the angle adjustment mechanism 3 as a whole can thus be removed from the side of the anastomosis member having the larger opening. Meanwhile, for the convenience of assembly, as shown in fig. 2, the side of the chuck table 222 near the large opening is constructed as an inclined surface to facilitate assembly.

Of course, in order to further prevent the relative sliding, the folded edge 311 may further include a plurality of first stopper portions 3111 configured as bayonets, and the corresponding locking platform 222 may further include a plurality of protrusions (not shown) engaged with the first stopper portions 3111. Similarly, at least a portion of the edge of the folded edge 311 forms a straight section to form a second limiting portion 3113, and a step surface matched with the second limiting portion 3113 is correspondingly disposed on the clamping table 222.

In the example of fig. 6 provided by the present invention, another embodiment is proposed, in which this embodiment differs from the previous embodiment. The anastomosis member 22 in the above-described embodiment is preferably made of medical grade silicone, but considering that the patient should be concerned about the angle of the drip-injection head, it should be emphasized that it is preferably made of medical grade silicone which is transparent to light. In the solution shown in fig. 6, the light transmittance of the anastomosis member 22 does not need to be considered, but instead, a plurality of light-transmitting portions 221 are disposed on the periphery of the anastomosis member, and during actual processing, the main body of the anastomosis member 22 is often made of a non-light-transmitting or weakly light-transmitting silicone material, and the light-transmitting portions 221 are light-transmitting holes processed in a hollow manner. Compared to being transparent or opaque as a whole. The scheme of the light hole enables the sight line of a patient to be attracted to one position more easily, and the problem that eye drops are blocked due to blinking reaction to cause infusion failure is reduced.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
