Description

Technical Field

[0001] This utility model relates to the field of veterinary pet clinical technology, and in particular to a corneal sensor for pets. Background Technology

[0002] In veterinary clinical practice, corneal sensitivity is an important indicator to aid veterinarians in diagnosing certain diseases. However, there is currently a lack of instruments specifically designed to assess corneal sensitivity in veterinary clinics. The existing Cochet-Bonnet corneal sensor, used in human clinical practice, presents several drawbacks when applied to veterinary settings. Firstly, animals like dogs and cats may observe the instrument during measurement, leading to instinctive blinking and inaccurate results. Secondly, dogs and cats are prone to non-cooperation, potentially causing mechanical collisions with the metal instrument during struggles. Because the instrument's tip is sharp and hard, and close to the animal's eye, it can easily cause severe iatrogenic damage to the cornea and other delicate facial tissues. Utility Model Content

The slider is slidably connected to the sliding hole and can slide and be limited to a set position under the push of an external force. The mouthpiece is detachably connected to the first end of the cylindrical body, and the mouthpiece is provided with a guide hole along the direction of the cylindrical body. The side of the mouthpiece away from the cylindrical body is spherical. One end of the measuring line is detachably connected to the slider, and the other end is used to pass through the guide hole to contact the cornea of ​​the pet to be tested. The measuring line can be controlled to extend beyond the mouthpiece by the sliding member. The pen clip is detachably connected to the second end of the cylindrical body to clamp the cylindrical body onto a clothing pocket.

[0006] Preferably, the outer wall of the cylinder is provided with scale lines along the length direction of the sliding hole.

[0007] Preferably, the slider includes a push handle and an elastic damping element. The elastic damping element is fitted into the sliding hole and can slide damped along the length direction of the sliding hole and be limited to a set position. The push handle is fixedly connected to the elastic damping element and extends out of the sliding hole so that the elastic damping element can slide in the sliding hole under the push of an external force. One end of the measuring line is detachably connected to the elastic damping element.

[0008] Preferably, the measuring line includes a nylon wire and a lug, the lug being fixedly connected to one end of the nylon wire, the lug being provided with a first external thread, the elastic damping member having a first through hole in the middle, and the end of the first through hole away from the nozzle being provided with a first external thread, the end of the nylon wire away from the lug being used to pass through the first through hole and extend out from the guide hole, and the first external thread being used to be threadedly connected with the first internal thread.

[0014] Preferably, the length of the cylinder is 80-100mm, the diameter of the cylinder is 6-8mm, and the range of the scale line is 50mm.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] This utility model provides a corneal sensor for pets, which is equipped with a sliding hole to provide a sliding track for the slider, so that the slider can move on a specified path. The operator can flexibly adjust the position of the slider to change the extension length of the measuring line according to the measurement needs.

[0017] A guide hole is provided in the middle of the mouthpiece to accurately guide the measuring filament through, ensuring that the measuring filament accurately reaches the pet's cornea for measurement.

[0018] The slider can be limited to a set position, ensuring the stability of the slider's position during measurement, thereby ensuring the stability of the measurement line extension length, improving the accuracy and repeatability of the measurement, and avoiding measurement errors caused by accidental sliding of the slider.

[0019] The mouthpiece is detachable, making it easy to replace in different measurement scenarios and with different needs. For example, it is convenient to operate when the mouthpiece is damaged or when it is necessary to replace it with a mouthpiece that is suitable for different pet species.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The purpose of this invention is to provide a corneal sensor for pets to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the accuracy of measurement results, and effectively avoids harming pets.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This utility model provides a corneal sensor for pets, such as Figures 1-2As shown, the instrument includes: a cylinder 1, a slider 2, a mouthpiece 3, a measuring line 4, and a pen clip 5. The cylinder 1 has a first end and a second end arranged opposite to each other, and the cylinder 1 is provided with an elongated sliding hole. The slider 2 is slidably connected to the sliding hole and can slide and be limited to a set position under the push of external force. The mouthpiece 3 is detachably connected to the first end of the cylinder 1, and a guide hole is provided in the middle of the mouthpiece 3. The side of the mouthpiece 3 away from the cylinder 1 is spherical. One end of the measuring line 4 is detachably connected to the slider 2, and the other end is used to pass through the guide hole to contact the cornea of ​​the pet. The measuring line 4 can be controlled to extend beyond the mouthpiece 3 under the action of the slider 2. The pen clip 5 is detachably connected to the second end of the cylinder 1 to clamp the cylinder 1 onto a clothing pocket. The cylinder 1 serves as the basic frame of the entire instrument, providing the main structure for the installation and support of other components. The sliding hole provides a sliding track for the slider 2, allowing it to move along a designated path. This lays the foundation for precise control of the extension length of the measuring line 4, facilitating accurate subsequent measurements of pet corneal sensitivity. The slider 2 can slide within the sliding hole, allowing operators to flexibly adjust its position to change the extension length of the measuring line 4 according to measurement needs. It can also be limited to a set position, ensuring the stability of the slider 2's position during measurement, thereby ensuring the stability of the measuring line 4's extension length, improving measurement accuracy and repeatability, and preventing measurement errors caused by accidental sliding of the slider 2. The mouthpiece 3 is detachable, facilitating replacement in different measurement scenarios and with different needs. For example, it allows for convenient operation when the mouthpiece 3 is damaged or needs to be replaced with a suitable mouthpiece 3 for different pet species. A guide hole in the middle of the mouthpiece 3 accurately guides the measuring line 4 through, ensuring that the measuring line 4 accurately reaches the pet's cornea for measurement. The mouthpiece 3, located away from the tube 1, has a spherical surface. This design conforms to the physiological structure of a pet's eye. When the pet struggles and collides mechanically with the instrument, the spherical surface of the mouthpiece 3 reduces the risk of corneal damage compared to other shapes, improving safety and comfort during the measurement process. The measuring line 4 is detachably connected to the slider 2, facilitating replacement when the measuring line 4 is damaged or its length needs adjustment. The length of the mouthpiece 3 extending outward can be controlled by the slider 2, allowing the measurement personnel to precisely adjust the extension length of the measuring line 4 according to the actual needs of the pet's corneal sensitivity measurement, thereby obtaining more scientific and accurate measurement data to accommodate the differences in corneal sensitivity among individual pets.

[0030] The pen clip 5 is detachable, allowing it to be removed when not in use, reducing the instrument's size for easier storage; it can also be easily installed when needed. It allows the tube 1 to be clipped into a doctor's coat pocket, greatly improving the instrument's portability and enabling doctors to easily access the corneal sensor for measurements during clinical work, thus increasing work efficiency.

[0031] In a preferred embodiment, the outer wall of the cylinder 1 is provided with a scale line 11 along the length of the sliding hole. The scale line 11, positioned along the length of the sliding hole, visually displays the position of the sliding member 2 within the sliding hole, thus clearly indicating the length of the measuring line 4 extending beyond the nozzle 3. During operation, the external force can accurately control the extension length of the measuring line 4 according to the scale line 11, making the measurement process more precise and standardized, reducing inaccuracies caused by human error, and further improving the reliability of the measurement results.

[0032] In a preferred embodiment, the slider 2 includes a push handle 21 and an elastic damping element 22. The elastic damping element 22 is fitted into the sliding hole and can slide damped along the length of the sliding hole and be limited to a set position. The push handle 21 is fixedly connected to the elastic damping element 22 and extends out of the sliding hole so that the elastic damping element 22 can slide within the sliding hole under the push of an external force. One end of the measuring line 4 is detachably connected to the elastic damping element 22. The slider 2 adopts a combination design of push handle 21 and elastic damping element 22. The push handle 21 facilitates operation by external force, and pushing the push handle 21 can easily drive the elastic damping element 22 to slide within the sliding hole. The damping sliding characteristics of the elastic damping element 22 give the slider 2 a certain resistance during the sliding process, which makes it easier for the operator to control the moving speed and stopping position of the slider 2 more accurately, thereby controlling the extension length of the measuring line 4 more precisely. At the same time, the elastic damping element 22 can be limited to a set position to ensure that the position of the slider 2 will not change due to accidental shaking during the measurement process, providing stable conditions for accurate measurement. Furthermore, the measuring line 4 and the elastic damping element 22 are detachably connected, which facilitates the maintenance and replacement of the measuring line 4. Preferably, the elastic damping element 22 is made of rubber or polypropylene. The elastic damping element 22 can be cylindrical, with a diameter slightly larger than the inner diameter of the cylinder so that the elastic damping element 22 can be limited to the set position without external force pushing the push handle 21.

[0033] In a preferred embodiment, the measuring line 4 includes a nylon wire 41 with a certain tensile strength and a lug 42. The lug 42 is fixedly connected to one end of the nylon wire 41 and is provided with a first external thread. The elastic damping member 22 has a first through hole in its middle, and the end of the first through hole away from the nozzle 3 is provided with a first external thread. The end of the nylon wire 41 away from the lug 42 is used to pass through the first through hole and extend out from the guide hole. The first external thread is used to connect with the first internal thread. The measuring line 4 adopts the structure of nylon wire 41 and lug 42. The nylon wire 41 has a certain degree of flexibility and strength, which can ensure that it is not easy to break during the measurement process and can achieve flexible position adjustment. The lug 42 is provided with an external thread that engages with the internal thread on the elastic damping member 22. This not only realizes the detachable connection between the measuring line 4 and the elastic damping member 22, making it easy to replace the measuring line 4, but also this threaded connection method has good stability and can be firmly connected during the measurement process, ensuring that the measuring line 4 moves accurately under the action of the slider 2, thus ensuring the accuracy of the measurement.

[0034] In a preferred embodiment, the mouthpiece 3 is made of silicone. Silicone is soft and skin-friendly, which reduces irritation and damage to the pet's cornea when it comes into contact with it, minimizing discomfort and resistance, thus facilitating a smooth measurement process. Furthermore, silicone has elasticity and wear resistance, ensuring the shape stability of the mouthpiece 3 during use and allowing it to withstand a certain degree of friction and impact, extending its lifespan.

[0035] In a preferred embodiment, the nozzle 3 has a second external thread on the side near the cylinder 1, and a second internal thread at the first end of the cylinder 1. The second external thread is used for threaded connection with the second internal thread, and the nozzle 3 and the cylinder 1 are connected by a thread. This connection method makes installation and disassembly very convenient. When it is necessary to clean the nozzle 3 or replace it with different types to adapt to different measurement needs, the threaded connection can be used to quickly complete the operation. Moreover, compared with other connection methods, the threaded connection can provide a tighter fixation effect, making the nozzle 3 less likely to loosen during measurement, thus ensuring the stability and accuracy of the measurement.

[0036] In a preferred embodiment, the pen clip 5 includes a fixing part 51, an elastic clamping part 52, and an inlet part 53. The fixing part 51 is detachably connected to the second end of the cylinder 1. The elastic clamping part 52 is fixedly connected to the fixing part 51 and can form an elastic clamping position with the cylinder 1 between the elastic clamping part 52 and the cylinder 1. The inlet part 53 is integrally connected to the side of the elastic clamping part 52 away from the fixing part 51. The pen clip 5 adopts a structural design of fixing part 51, elastic clamping part 52, and inlet part 53. The fixing part 51 is detachably connected to the cylinder 1, which facilitates the installation and removal of the pen clip. The elastic clamping part 52 can form an elastic clamping position with the cylinder 1. This elastic design allows the pen clip to be firmly clamped on the coat pocket without damaging the coat pocket due to excessive clamping force, or falling off due to insufficient clamping force. The design of the inlet part 53 facilitates the accurate clamping of the pen clip onto the coat pocket by external force, improving ease of use.

[0037] In a preferred embodiment, the fixing part 51 is provided with a third external thread, and the second end of the cylinder 1 is provided with a third internal thread. The third external thread is used for threaded connection with the third internal thread. The fixing part 51 of the pen clip 5 and the cylinder 1 are connected by a thread, which provides convenient installation and disassembly while ensuring the connection is firm. In daily use and frequent clamping and retrieval operations, this threaded connection structure can effectively prevent the pen clip 5 from loosening or falling off, ensuring that the pen clip 5 is always stably installed on the cylinder 1, providing a reliable guarantee for the portability of the instrument.

[0038] In a preferred embodiment, the pen clip 5 is made of rigid resin material. Rigid resin material has a certain strength and rigidity, ensuring the structural stability of the pen clip 5. It is not easily deformed under long-term use and frequent opening and closing, ensuring that the pen clip always maintains good clamping performance. At the same time, rigid resin material is relatively lightweight, not adding too much weight to the entire instrument. While meeting functional requirements, it also ensures the overall portability of the instrument, which is beneficial for doctors to carry and use the instrument for extended periods.

[0039] In a preferred embodiment, the length of the cylinder 1 is 80-100mm, preferably 90mm, and the diameter of the cylinder 1 is 6-8mm, preferably 7mm. The range of the scale line 11 is 50mm. Reasonably limiting the length, diameter, and range of the scale line 11 makes the overall size of the instrument more suitable for actual clinical measurement operations and usage habits in pets. A suitable length and diameter of the cylinder 1 facilitates gripping and operation, preventing inconvenience due to excessive size or inaccuracy due to insufficient size. The 50mm range of the scale line 11 not only meets the actual needs of measuring pet corneal sensitivity but also allows for more reasonable scale division, facilitating reading of scale data and improving measurement accuracy and readability.

[0040] The instructions for using this pet corneal sensor are as follows:

[0041] Preparation: Ensure all instrument components are securely connected. Check that the measuring line 4 extends and retracts smoothly under the action of the slider 2, and that the mouthpiece 3 is correctly installed and undamaged. Simultaneously, restrain the pet to keep its head stable and fixed, preventing measurement errors or eye injuries caused by head movement during measurement. Specialized pet restraint tools can be used, or restraint can be performed with the assistance of an assistant.

[0042] Initial settings: Push the slider 2 to extend the measuring line 4 to the maximum range position (corresponding to 50mm at the scale line 11). At this time, the nylon filament 41 extends to a length of 50mm and has a diameter of 0.08mm. This is the lowest mechanical stimulation value, corresponding to the highest corneal sensitivity state.

[0043] Measurement Procedure: Gently bring the mouthpiece 3 close to the pet's eye, ensuring the tip of the nylon filament 4 touches the center of the cornea perpendicularly (ensuring the tangent at the contact point between the nylon filament and the cornea remains perpendicular). Then, apply a small force along the direction of the nylon filament 41, causing it to bend. Maintain a uniform and stable force each time to ensure consistency and comparability across multiple measurements. Perform the initial measurement on the pet's cornea and record whether the pet blinks. Repeat the above measurement procedure and requirements 5 times.

[0044] Result Interpretation and Adjustment: If the pet blinks less than 3 times out of 5 measurements, it indicates that the current length of the measuring line 4 does not stimulate the pet's cornea sufficiently to cause frequent blinking, and the measurement is considered negative. At this point, by manipulating slider 2, shorten the extension length of measuring line 4 by the smallest unit of measurement (5mm) (the movement of slider 2 shortens measuring line 4, and the shortened length can be visually displayed on the corresponding scale line 11). Then repeat the above measurement operation (perform 5 more measurements and record the blinking response). Repeat this cycle until 3 or more blinking responses occur within 5 measurements. At this point, it can be determined that the corneal sensitivity of the eye falls within the range of that value and its 5mm increment.

[0045] Precise Measurement: Starting from the point 5mm above the defined range, gradually shorten the length of the nylon thread 41 in 5mm increments. Perform the measurement operation as described in step 3 five times for each shortening, until a blinking response occurs more than three times within those five measurements. Record the extension length of the measurement line 4 corresponding to the scale line 11 at this point. This reading is the corneal sensitivity value for that eye of the animal.

[0046] Measurement complete: After measurement, move slider 2 to the position where the measuring line 4 extends to its minimum length, carefully remove mouthpiece 3, and then clip the instrument into the doctor's coat pocket using pen clip 5 for safekeeping. Clean the instrument; if the measuring line 4 or mouthpiece 3 shows obvious wear or contamination, replace it promptly for future use.

[0047] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
