[0002] Currently, dry eye disease (DED) is the most common ocular surface disease, mainly manifested as symptoms such as eye dryness, stinging pain, burning sensation, and foreign body sensation. At the same time, it can be accompanied by ocular surface inflammatory reactions, tissue damage, and nerve abnormalities. DED is a chronic eye disease, and repeated attacks will seriously affect the daily life of patients, reducing work efficiency and quality of life. The vibrating dry eye treatment instrument contacts the vibrating treatment head with the soft tissue outside the nasal bone of the patient, transmits the vibration to the patient's nose, generates stimulation, and promotes tear secretion through the nasolacrimal reflex to achieve the purpose of treating dry eye. However, due to individual differences among dry eye patients, the frequency and amplitude of vibration required for each patient to produce the nasolacrimal reflex are different.

The driving part can drive the vibrating part to drive the vibrating head to vibrate and stimulate the nasal nerve of the patient, and promote the distribution of human tears through the nasolacrimal reflex.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The purpose of the present invention is to provide a lacrimal fluid secretagogue to solve the problems existing in the prior art and be able to adjust the vibration frequency.

[0027] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The present invention provides a lacrimal fluid secretagogue, as Figure 1-4 shown, which includes a housing 1, a vibration head 2, a vibration piece 3, a vibration assembly 4 and a processor 5. Both ends of the vibration piece 3 are fixedly connected to the housing 1. The side of the vibration piece 3 facing the housing 1 is fixedly connected to the vibration assembly 4, and the other side is fixedly connected to one end of the vibration head 2. The end of the vibration head 2 away from the vibration piece 3 is used to contact the patient. The processor 5 is signal-connected to the vibration assembly 4. The vibration assembly 4 can vibrate and can drive the vibration piece 3 to vibrate in a direction perpendicular to the side surface of the vibration piece 3. The vibration piece 3 can drive the vibration head 2 to vibrate, and the processor 5 can adjust the vibration frequency of the vibration assembly 4.

[0029] The lacrimal fluid secretagogue provided by the present invention can be used for the treatment of dry eye. During use, the vibration head 2 is contacted with the patient's nose. The vibration assembly 4 drives the vibration piece 3 to vibrate, and the vibration piece 3 drives the vibration head 2 to vibrate, so that the vibration can be used to promote the lacrimal gland of the patient to secrete tears, thereby treating the patient. By controlling the vibration frequency of the vibration assembly 4 through the processor 5, and then changing the vibration frequency of the vibration head 2, the adjustment of the vibration frequency of the vibration head 2 can be realized, so as to meet the treatment needs of different patients. To ensure the treatment effect, the vibration frequency of the vibration assembly 4 is preferably adjustable within the range of 100 Hz - 300 Hz.

[0030] Specifically, the processor 5 preferably uses a single-chip microcomputer of the STM32 or GD32 series. The processor 5 also includes a communication module for receiving computer commands, and the refined adjustment of the vibration frequency can be realized through the program of the computer; the communication module is preferably a wired USB2.0 or a wireless Bluetooth module. It should be noted that the computer program and the processor module for frequency adjustment provided by the present invention are all existing technologies.

[0031] In a preferred embodiment of the first embodiment, the processor 5 can adjust the vibration amplitude of the vibration assembly 4. The processor 5 is preferably provided with an amplified signal circuit, and the use of the amplified signal circuit can achieve precise adjustment of the vibration amplitude of the eccentric motor 41, thereby further meeting the different needs of different patients.

[0032] In a preferred embodiment of the first embodiment, there is an accommodation cavity inside the housing 1. A working port 11 communicating with the accommodation cavity is provided on one side of the housing 1. Both ends of the vibrating piece 3 are fixedly connected to the housing 1 on opposite sides of the working port 11. The vibration assembly 4 is arranged inside the accommodation cavity, and the vibration head 2 is arranged outside the accommodation cavity. The arrangement of the vibration assembly 4 inside the accommodation cavity can enable the housing 1 to protect the vibration assembly 4, thereby preventing the vibration assembly 4 from colliding with the outside and also preventing dust from affecting the vibration assembly 4.

[0033] In a preferred embodiment of the first embodiment, the vibration head 2 and the vibration assembly 4 are respectively fixedly connected to the midpoints on both sides of the vibrating piece 3. The vibration head 2 and the vibration assembly 4 being located at the midpoints on both sides of the vibrating piece 3 can increase the vibration amplitude of the vibration head 2, thereby meeting the treatment needs of patients.

[0034] In addition, the vibration amplitude can be further increased by changing the vibration frequency of the vibration assembly 4. The principle is as follows:

[0035] According to the vibration analysis model, the length of the vibrating piece 3 is L, and the positions where both ends of the vibrating piece 3 are fixedly connected are x = 0 and x = L. At this time, the vibration equation of the vibrating piece 3 can be expressed as formula (1):

[0036]

[0037] In the formula T is the tension of the vibrating piece 3, and ρ is the mass per unit length of the vibrating piece 3.

[0038] The vibration of the vibrating piece 3 can be expressed as formula (2):

[0039]

[0040] In the formula, b n and are the undetermined coefficients corresponding to the nth-order vibration.

[0041] From formula (2), it can be obtained that when n = 1, the oscillation fundamental frequency of the vibrating piece 3 is:

[0042]

[0043] Therefore, when the vibration frequency of the vibration assembly 4 is equal to the vibration fundamental frequency of the vibrating piece 3, that is, in the resonance state, the vibration amplitude of the vibration head 2 reaches the maximum value.

[0044] According to the above conclusions, during use, the vibration frequency of the vibration component 4 can be adjusted to make the vibration frequency of the vibration component 4 the same as the vibration frequency of the vibration plate 3, thereby increasing the vibration amplitude of the vibration head 2 to meet the patient's treatment needs.

[0045] In a preferred implementation scheme of this embodiment, the part where the vibration plate 3 is fixedly connected to the vibration head 2 and the vibration assembly 4 is the connection part 31, and the other part is the vibration part 32.

When the vibration part 32 is a corrugated sheet, during the vibration process, the vibration part 32 can be extended in the vibration direction, and the vibration amplitude is larger than that of the vibration part 32 whose side is a plane. Therefore, when it is necessary to manufacture a tear secretion promoting instrument with a smaller vibration amplitude, it is preferred to use the first type of vibration part 32; when it is necessary to manufacture a tear secretion promoting instrument with a larger vibration amplitude, it is preferred to use the second type of vibration part 32.
