Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a neonatal fundus observation device. Background Technology

[0002] Currently, if a newborn's eyes have problems, doctors need to first observe the surface of the eye, and during this observation, they need to examine the fundus, such as the iris and sclera. Because the eyes are small, doctors often need to use magnifying glasses for this observation, which is quite inconvenient. For younger patients, such as children or infants, they often instinctively move their eyeballs, making it difficult for medical staff to observe the fundus.

[0003] The problems compared with existing technologies are as follows: Since the eyes of newborns vary in size, different types of lenses need to be used during observation. However, existing observation equipment is not convenient for quick lens replacement. The required lens needs to be installed in a designated position, and the lens will be exposed to the outside during the replacement process, which will cause contamination and lead to inaccurate observation. To address these problems, we propose a new neonatal fundus observation device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a neonatal fundus observation device.

[0005] The present invention solves its technical problem through the following technical solution: it includes a mounting housing, an observation mechanism is provided on the top of the mounting housing, the observation mechanism includes a mounting plate, the mounting plate is fixed to the top of the mounting housing, a sealing lens is fixed on the inner wall of the mounting plate, a support sleeve is fixed on the bottom of the mounting plate, an installation sleeve is fixed on the bottom of the mounting housing, a first lens is fixed on the inner wall of the installation sleeve, a positioning rubber ring is provided on the bottom of the installation sleeve, and a switching mechanism is provided inside the mounting housing;

[0006] The switching mechanism includes a mounting rod rotatably connected to the inner wall of the mounting housing. A switching knob is fixed to the top of the mounting rod, and a drive bracket is fixed to the outer side of the mounting rod. Multiple mounting rings are fixed to the outer side of the drive bracket, and a second lens is fixed to the inner wall of each of the multiple mounting rings. A positioning mechanism is provided on the outer side of the switching mechanism.

[0007] As a further improvement of this utility model: a mounting bracket is fixed to one side of the mounting housing by bolts, and a handle is fixed to one side of the mounting bracket by bolts.

[0008] As a further improvement of this utility model, a protective rubber ring is fixed to the top of the mounting plate.

[0009] As a further improvement of this utility model, a retaining ring is fixed to the outer side of the mounting sleeve.

[0010] As a further improvement of this utility model: a digital indicator is provided on the top of the drive bracket, and a glass observation window is fixed on the inner wall of the mounting housing near the mounting rod.

[0011] As a further embodiment of this utility model: the positioning mechanism includes a ring body, which is fixed to the top of the mounting housing. The inner wall of the ring body is provided with multiple slots. A rotating block is fixed to the outer side of the mounting rod near the drive bracket. Multiple sliding grooves are provided on the outer side of the rotating block. Positioning blocks are slidably connected to the inner walls of the multiple sliding grooves. A spring is fixed to one side of the positioning block.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. Before using the equipment, the second lens of the specified model is moved to the support sleeve part by the switching mechanism according to the usage requirements. The observation mechanism is used for observation. The second lens can be quickly switched according to the usage requirements. The multiple second lenses are sealed inside the mounting housing, so the second lens will not be contaminated during the switching operation, ensuring the cleanliness of the second lens during the observation operation and improving the accuracy of the observation operation.

[0014] 2. Different models of second lenses are labeled by a digital indicator panel. During the switching operation, the label corresponding to the second lens in the position of use is displayed on the glass observation window, which makes it convenient for users to directly observe the model of the second lens being used and ensures the accuracy of the switching operation.

[0015] 3. By incorporating a positioning mechanism, during switching operations, the rotating block is driven to rotate by the rotation of the mounting rod. The rotation of the rotating block causes multiple positioning blocks to slide on the inner wall of the ring. These positioning blocks correspond to the mounting ring. When the mounting ring moves to the usage position, the positioning blocks abut against the slot under the action of springs, achieving step-by-step rotation of the rotating block. This locks and positions the mounting ring, ensuring that it will not move without external force. This guarantees that the second lens will not move during use, thus ensuring the stability of the observation operation. Attached Figure Description

[0028] Please see Figure 1-7 This utility model provides a technical solution: it includes a mounting housing 100, a mounting bracket 110 fixed to one side of the mounting housing 100 by bolts, a handle 120 fixed to one side of the mounting bracket 110 by bolts, an observation mechanism provided on the top of the mounting housing 100, the observation mechanism including a mounting plate 210, a sealing lens 220 and a support sleeve 230, a mounting sleeve 240 fixed to the bottom of the mounting housing 100, a first lens 250 fixed to the inner wall of the mounting sleeve 240, a positioning rubber ring 260 provided at the bottom of the mounting sleeve 240, and a switching mechanism provided inside the mounting housing 100;

[0029] The switching mechanism includes a mounting rod 310, a switching knob 320, and a drive bracket 330. Multiple mounting rings 340 are fixed to the outer side of the drive bracket 330, and a second lens 350 is fixed to the inner wall of each of the mounting rings 340. A positioning mechanism is provided on the outer side of the switching mechanism. Before using the equipment, the switching mechanism moves the specified model of the second lens 350 to the support sleeve 230 according to usage requirements. The observation mechanism allows for quick switching of the second lens 350 according to usage needs. Furthermore, the multiple second lenses 350 are sealed inside the mounting housing 100, preventing contamination during switching operations and ensuring the cleanliness of the second lenses 350 during observation, thus improving the accuracy of the observation operation.

[0030] Specifically, a protective rubber ring 221 is fixed to the top of the mounting plate 210; by providing the protective rubber ring 221 to protect the sealing lens 220, the collision of the top of the equipment can be buffered and protected.

[0031] Specifically, a retaining ring 241 is fixed on the outer side of the mounting sleeve 240; the retaining ring 241 facilitates the accurate installation of the positioning rubber ring 260 at the bottom of the mounting sleeve 240, and at the same time, it can limit and fix the positioning rubber ring 260 to prevent it from falling off during use, thus ensuring the accuracy of the positioning operation of the positioning rubber ring 260 for the observation part.

[0032] Specifically, a digital indicator 331 is provided on the top of the drive bracket 330, and a glass observation window 332 is fixed on the inner wall of the mounting housing 100 near the mounting rod 310. Different models of second lenses 350 are marked by the digital indicator 331. During the switching operation, the marking corresponding to the second lens 350 in the usage position is displayed in the glass observation window 332, which makes it convenient for the user to directly observe the model of the second lens 350 used and ensures the accuracy of the switching operation.

[0033] Specifically, the positioning mechanism includes a ring 410, which is fixed to the top of the mounting housing 100. The inner wall of the ring 410 has multiple slots 420. A rotating block 430 is fixed to the outer side of the mounting rod 310 near the drive bracket 330. Multiple sliding grooves 440 are provided on the outer side of the rotating block 430. Positioning blocks 450 are slidably connected to the inner walls of each of the sliding grooves 440. A spring 451 is fixed to one side of each positioning block 450. By providing this positioning mechanism, during switching operations, the rotating block is driven by the rotation of the mounting rod 310. Rotating at 430, the rotating block 430 drives multiple positioning blocks 450 to slide on the inner wall of the ring body 410. The multiple positioning blocks 450 correspond to the mounting ring 340. When the mounting ring 340 moves to the use position, the positioning blocks 450 abut against the slot 420 under the action of the spring 451, realizing the step rotation of the rotating block 430. This can lock and position the mounting ring 340. Without applying external force, the mounting ring 340 will not move, ensuring that the second lens 350 will not move during use, thus ensuring the stability of the observation operation.

[0034] Working Principle: Before using the device, the user turns the switching knob 320. The rotation of the knob 320 drives the mounting rod 310, which in turn drives the drive bracket 330. The drive bracket 330 then drives multiple mounting rings 340 and the second lens 350. The user moves the specified second lens 350 to the support sleeve 230 according to their needs. The mounting sleeve 240 is aligned with the newborn's eyes. The user holds the handle 120, and the positioning rubber ring 260 is pressed against the newborn's eye socket to locate the area to be observed in the fundus. The user observes the newborn's fundus through the sealed lens 220, the second lens 350, and the first lens 250. The user can quickly switch between the second lenses 350 as needed. Since the multiple second lenses 350 are sealed inside the mounting housing 100, they are not contaminated during switching operations, ensuring the second lens's visibility. The cleanliness of the lens 350 during observation is indicated by the digital indicator 331, which marks different models of the second lens 350. During switching operations, the markings corresponding to the second lens 350 in the usage position are displayed on the glass observation window 332, allowing the user to directly observe the model of the second lens 350 being used. During switching operations, the rotating block 430 is rotated by the rotation of the mounting rod 310. The rotation of the rotating block 430 causes multiple positioning blocks 450 to slide on the inner wall of the ring 410. The multiple positioning blocks 450 correspond to the mounting ring 340. When the mounting ring 340 moves to the usage position, the positioning blocks 450 abut against the slot 420 under the action of the spring 451, realizing the step rotation of the rotating block 430 and locking the mounting ring 340 in place. The mounting ring 340 will not move without the application of external force, ensuring that the second lens 350 will not move during use.
