Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a pen light with adjustable visual targets. Background Technology

[0002] In ophthalmological clinical diagnosis and treatment, strabismus is a common eye disease, and its accurate diagnosis is crucial for subsequent treatment and the recovery of the patient's visual function. Currently, the comprehensive examination combining corneal light reflex test and accommodative target test is an important means of diagnosing strabismus. The corneal light reflex test can preliminarily determine the eye deviation, while the accommodative target test is used to assess accommodative function.

[0003] However, existing examination tools have significant shortcomings. Current examinations rely on two separate devices: a point-source pen lamp and an independently accommodating target. The point-source pen lamp can only provide light for corneal reflex examination and cannot induce an accommodative response; while the independently accommodating target can induce accommodation, it lacks accompanying illumination, limiting its use.

[0004] This separate design makes the examination process cumbersome and inefficient. Doctors need to frequently switch and adjust between the two, which seriously affects the continuity of the examination and increases the difficulty of operation. Especially in the examination of pediatric patients, due to their poor cooperation, the examination needs to be completed quickly, but the existing tools obviously cannot meet this need. The excessively long examination time may cause children to develop resistance, further increasing the difficulty of the examination.

[0005] Furthermore, carrying and storing two separate devices is inconvenient for medical staff and increases their workload. Although some patents have attempted to improve portability, the structures remain complex and the ease of operation is lacking. Therefore, developing an integrated examination tool that organically combines a point light source with an adjustable target to simplify operation and improve efficiency and accuracy has significant clinical application value. Utility Model Content

[0006] In view of the problems and shortcomings of the existing technology, this utility model provides a pen lamp with adjustable visual targets.

[0007] The technical solution of this utility model is as follows:

[0008] A pen lamp with an adjustable target includes a pen lamp body, on which an adjustable target is fixed by a rotatable buckle;

[0009] A fixing device is provided on the side of the pen lamp body near the light source emission end. The fixing device is connected to the adjustment target through a rotating shaft. The adjustment target can be rotated around the rotating shaft to a state that is upright perpendicular to the axis of the pen lamp body or in a state that is horizontal parallel to the axis of the pen lamp body. The rotatable buckle is provided on the side of the pen lamp body to fix the upright position of the adjustment target.

[0010] The adjustment target is a replaceable design, and its surface is marked with patterns or text for strabismus examination.

[0011] A rotatable buckle is located on the side of the pen lamp body. It adopts a mechanical buckle structure to provide additional fixed support when adjusting the sight to stand up, ensuring stability.

[0012] The pivot is a damped pivot, which can keep the position fixed when the target is rotated to any angle.

[0013] The sight beacon is equipped with a replaceable sight beacon plate, which has patterns or text markings.

[0014] The surface of the adjustable target is coated with a reflective or fluorescent coating to enhance visibility in low-light environments.

[0015] The pen lamp's main body houses a light source and a power module. The light source is controlled by a switch. The light source is an LED. The power module is a rechargeable lithium battery, and a USB charging port is located at the rear of the pen lamp's main body.

[0016] The pen lamp's main body is made of medical-grade plastic or metal, and its internal circuitry is waterproof.

[0017] In addition, a storage slot is provided at the rear of the pen lamp body. When the adjustable target is laid down, the adjustable target part is embedded in the storage slot, reducing the space occupied.

[0018] The beneficial effects of this utility model are:

[0019] A pen lamp with adjustable sight targets

[0020] This invention significantly improves the convenience and accuracy of strabismus examination by integrating the accommodative target and pen light into a single design. During the examination, only one hand is needed to simultaneously provide a point light source and accommodative target, avoiding the cumbersome process of frequently changing tools in traditional examinations. This is especially suitable for patients with low cooperation levels, such as children. The rotatable target design ensures stability during examination and facilitates storage and portability, effectively solving the problems of large size and easy damage of traditional accommodative targets. The synergistic effect of the light source and target can more accurately stimulate the patient's accommodative function, making corneal reflex examination results more reliable. Furthermore, this invention adopts a modular design, allowing for target replacement to adapt to different examination needs, while maintaining a compact and durable overall structure with good clinical application value.

[0026] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0027] Example

[0028] See Figures 1-3 As shown, a pen lamp with an adjustable sight 3 includes a pen lamp body 1, on which the adjustable sight 3 is fixed by a rotatable buckle 2.

[0029] See Figure 1 A fixing device 4 is provided on the side of the pen lamp body 1 near the light source emission end. The fixing device 4 is connected to the adjustment target 3 through a rotating shaft 5. The adjustment target 3 can rotate around the rotating shaft 5 to a state that is upright perpendicular to the axis of the pen lamp body 1 or in a state that is horizontal parallel to the axis of the pen lamp body 1. The rotatable buckle 2 is provided on the side of the pen lamp body 1 and is used to fix the upright position of the adjustment target 3.

[0030] The pen lamp body 1 has a cylindrical structure, with the outer shell made of medical-grade ABS plastic or aluminum alloy. Internally, it houses a light source and a power module. The light source is a high-brightness LED, controlled by a switch. The power module is a rechargeable lithium battery, with a USB charging port at the rear supporting fast charging. The outer shell of the pen lamp body 1 is made of medical-grade plastic or metal, and the internal circuitry is waterproof.

[0031] The adjustment target 3 is connected to the fixing device 4 on the top of the pen lamp body 1 via a rotating shaft 5. The rotating shaft 5 is a damped rotating shaft 5, which allows the adjustment target 3 to remain fixed at any angle, preventing shaking from affecting the results during inspection. The adjustment target 3 is equipped with a replaceable target plate 31 (see attached image). Figure 3 The surface of the target plate 31 is provided with patterns or text markings for strabismus inspection and is coated with a reflective coating to enhance visibility in low-light environments.

[0032] The rotatable buckle 2 is located on the side of the pen lamp body 1 and adopts a mechanical buckle structure to provide additional fixed support when adjusting the sight 3 to ensure stability.

[0033] In addition, a storage slot is provided at the rear of the pen lamp body 1. When the adjustment target 3 is laid down, part of the adjustment target 3 is embedded in the storage slot, reducing the space occupied.

[0034] Working principle: During the examination, the accommodating target 3 is rotated to an upright position and secured with the rotatable buckle 2, and the light source is turned on. The patient focuses on the target pattern, and the doctor observes the eye position using corneal reflexology. After the examination, the accommodating target 3 is laid down and folded into the storage slot. This invention, through its integrated design, achieves the synergistic use of the point light source and the accommodating target 3, significantly improving examination efficiency and accuracy. Furthermore, the target is replaceable to adapt to different examination needs, and the overall structure is compact and durable, possessing significant clinical application value.
