Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a fundus examination device with an auxiliary alignment function. Background Art

[0002] Fundus examination plays a vital role in the diagnosis of ophthalmic diseases and the identification and judgment of certain diseases in internal medicine and neurology. It is an indispensable key means for diagnosing ophthalmic diseases. Through fundus examination, medical staff can obtain detailed information about the fundus and provide a basis for accurate diagnosis of the disease. In the actual fundus examination operation, medical staff often need to use auxiliary alignment devices to ensure the smooth progress of the examination. This is because, in order to obtain accurate and clear fundus images, the patient's pupil must be accurately aligned with the observation window of the inspection instrument. However, fundus examination usually takes a long time, and during this long examination process, patients are very likely to feel tired. As fatigue accumulates, patients will unconsciously move their heads.

[0003] The auxiliary alignment device currently used lacks an effective fixation mechanism for the patient's head. When the patient moves his head due to fatigue due to long-term examination, the relative position between the originally aligned pupil and the observation window of the examination instrument will deviate, thereby affecting the medical staff's examination of the patient's fundus and reducing the efficiency of the examination. Summary of the invention

[0004] The main purpose of the present invention is to provide a fundus examination device with auxiliary alignment function to overcome the problems existing in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A fundus examination device with an auxiliary alignment function comprises a base, a fixing plate is provided on the front side of the base, a connecting rod is provided on the top of the fixing plate, auxiliary components are provided at both ends of the connecting rod, and two groups of auxiliary components are provided, each group of the auxiliary components comprises two connecting blocks, both ends of the two connecting blocks are rotatably connected to a rod body, one side of the two connecting blocks is provided with an elastic rubber sheet, and the two ends of the elastic rubber sheet are respectively rotatably connected to the corresponding rod body.

[0007] Through the above technical solution, the elastic rubber sheet can actively adapt to the contour of the patient's head. This close-fitting design can effectively avoid local pressure points on the patient's head. Unlike traditional rigid fixation devices, it can be adaptively adjusted according to the specific shape of the patient's head, making the patient feel more comfortable during the examination.

[0008] Furthermore, blocks are provided at both ends of the connecting rod, and tracks are provided on the sides of the two blocks facing each other.

[0009] Furthermore, the inner sides of the two rails are slidably connected with sliders, and the ends of the two sliders facing each other are fixedly connected with a plate body.

[0010] Through the above technical solution, when the patient's head is placed above the arc section of the bracket, the tracks on both sides drive the slider to approach the patient's head, so that the elastic rubber sheet contacts both sides of the patient's head.

[0011] Furthermore, both ends of each of the plates are fixedly connected with springs, and one end of each of the springs away from the plate is fixedly connected to a corresponding rod.

[0012] Furthermore, a detector is provided on the top of the base, a slide rail is provided inside the base, and a slide rod is provided above the base.

[0013] Furthermore, a limit block is provided at the bottom of the detector, the front end of the detector is slidably connected to the slide rod, and the limit block at the bottom of the detector is slidably connected to the slide rail.

[0014] Through the above technical solution, medical staff can push the detector along the slide rail and the slide rod. The role of the limit block is to ensure that the detector will not fall off the slide rail during the sliding process, and at the same time play a certain guiding and positioning role, ensuring that the moving trajectory of the detector is along the predetermined straight line direction, thereby improving the stability and accuracy of the movement.

[0015] Furthermore, a bracket is provided at one end of the connecting rod, and the bracket is located below the two blocks. An arc section is provided in the middle of the bracket, and the arc section is made of a flexible material.

[0016] Through the above technical solution, when a patient undergoes fundus examination, the patient's forehead is against the positioning plate and the chin can be placed on the arc section of the bracket.

[0017] Furthermore, the detector is located on the front side of the bracket.

[0018] Furthermore, a positioning plate is provided at one end of the connecting rod, and the positioning plate is located above the two blocks.

[0019] Furthermore, pressure sensors are provided on the outer sides of the two elastic rubber sheets, and a controller is provided inside the base.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The elastic rubber sheet in the auxiliary component of the present invention can actively adapt to the contour of the patient's head. This close-fitting design can effectively avoid local pressure points on the patient's head. Unlike traditional rigid fixing devices, it can be adaptively adjusted according to the specific shape of the patient's head, making the patient feel more comfortable during the examination.

[0022] The auxiliary component of the present invention can effectively fix the head, which can effectively reduce the unconscious movement of the patient's head, thereby ensuring that the relative position of the patient's pupil and the observation window of the inspection instrument is more stable, which is conducive to medical staff to obtain clear and accurate fundus examination images;

[0023] During examination, the patient's forehead is against the positioning plate, and the chin can be placed on the arc section of the bracket. The arc section made of flexible material can produce a certain deformation according to the shape and weight of the patient's chin to better fit the chin and provide support for the head. This flexible deformation can evenly disperse the pressure of the head on the bracket, thereby improving the stability and comfort of the patient's head placement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0030] Combination Figures 1 to 4 The present embodiment provides a fundus examination device with an auxiliary alignment function, including a base 1, a fixing plate 5 is provided on the front side of the base 1, a connecting rod 6 is provided on the top of the fixing plate 5, auxiliary components are provided at both ends of the connecting rod 6, and two groups of auxiliary components are provided, each group of auxiliary components includes two connecting blocks 15, both ends of the two connecting blocks 15 are rotatably connected with a rod body 13, one side of the two connecting blocks 15 is provided with an elastic rubber sheet 14, and the two ends of the elastic rubber sheet 14 are respectively rotatably connected to the corresponding rod body 13.

[0031] When the patient undergoes fundus examination, the head is placed above the arc section of the bracket 7, and the patient's head is assisted in fixing and aligning by two sets of auxiliary components. After the patient's head is placed, the tracks 10 on both sides drive the slider 11 to approach the patient's head, so that the elastic rubber sheet 14 contacts both sides of the patient's head. The elastic rubber sheet 14, due to its certain elastic deformation, will actively adapt to the contour of the patient's head. When the elastic rubber sheet 14 is squeezed and bent, due to its rotational connection with the rod body 13, the rod body 13 will rotate accordingly, and the compression of the compression spring 12 will adapt to this change.

[0032] When the patient's examination is completed, the track 10 drives the slider 11 to move to both sides without fixing the patient's head. At this time, the spring 12 rebounds. Under the push of the elastic force of the spring 12, the rod body 13 can complete the reset action relatively smoothly and return to the angle state before the examination when it is not squeezed by the head. The rod body 13 can drive the elastic rubber sheet 14 to return to its initial state, presenting the original relatively flat and undeformed state, ready for the next use.

[0033] First, the elastic rubber sheet 14 in the auxiliary component can actively adapt to the contour of the patient's head. This close-fitting design can effectively avoid local pressure points on the patient's head. Unlike traditional rigid fixation devices, it can be adaptively adjusted according to the specific shape of the patient's head, making the patient feel more comfortable during the examination.

[0034] Secondly, the auxiliary components can maintain effective fixation of the head, which can effectively reduce the patient's unconscious head movement, thereby ensuring that the relative position of the patient's pupil and the observation window of the examination instrument is more stable, which is conducive to medical staff obtaining clear and accurate fundus examination images.

[0035] Reference Figure 3-Figure 4 Blocks 9 are provided at both ends of the connecting rod 6, and tracks 10 are provided on the opposite sides of the two blocks 9. Slide blocks 11 are slidably connected to the inner sides of the two tracks 10. The opposite ends of the two slide blocks 11 are fixedly connected to plates 16. Both ends of each plate 16 are fixedly connected to springs 12, and the end of each spring 12 away from the plate 16 is fixedly connected to the corresponding rod 13.

[0036] When the patient's head is placed on the arc section of the bracket 7, the tracks 10 on both sides drive the slider 11 to approach the patient's head, so that the elastic rubber sheet 14 contacts both sides of the patient's head.

[0037] The track 10 may be an electric slide rail in the prior art.

[0038] Reference Figure 1-Figure 2A detector 2 is provided on the top of the base 1, a slide rail 3 is opened inside the base 1, a slide rod 4 is provided above the base 1, a limit block is provided at the bottom of the detector 2, the front end of the detector 2 is slidably connected to the slide rod 4, and the limit block at the bottom of the detector 2 is slidably connected to the slide rail 3.

[0039] When the position of the detector 2 needs to be adjusted, for example, in order to better align the patient's eyes for fundus examination, the medical staff can push the detector 2 along the slide rail 3 and the slide rod 4. The function of the limit block is to ensure that the detector 2 does not separate from the slide rail 3 during the sliding process, and at the same time plays a certain guiding and positioning role, ensuring that the moving trajectory of the detector 2 is along the predetermined straight line direction, thereby improving the stability and accuracy of the movement. This design allows the position of the detector 2 on the horizontal plane to be flexibly adjusted according to the patient's position and specific examination requirements. Medical staff can easily move the detector 2 to the appropriate position through manual operation, so that the observation window of the detector 2 can be accurately aligned with the patient's pupil.

[0040] In this device, when the detector 2 is connected to the slide rail 3 and the front end to the slide rod 4 through the bottom limit block, a friction block is provided inside the slide rail 3, so that the detector 2 will generate a certain friction resistance when moving. When there is no external force acting on the detector 2 to move it, the friction force can keep the detector 2 in the current position. The medical staff can apply appropriate external force as needed to overcome the friction force and push the detector 2 to the ideal position. When the external force stops acting, the detector 2 can stop moving immediately instead of continuing to slide due to inertia or other factors, so that the medical staff can better control the position of the inspection equipment and ensure the smooth progress of the inspection process.

[0041] Reference Figure 1-Figure 2 A bracket 7 is provided at one end of the connecting rod 6, and the bracket 7 is located below the two blocks 9. An arc section is provided in the middle of the bracket 7, and the arc section is made of a flexible material. A positioning plate 8 is provided at one end of the connecting rod 6, and the positioning plate 8 is located above the two blocks 9. The detector 2 is located on the front side of the bracket 7.

[0042] When the patient undergoes fundus examination, the patient's forehead is against the positioning plate 8, and the chin can be placed on the arc section of the bracket 7. The arc section made of flexible material can produce a certain deformation according to the shape and weight of the patient's chin to better fit the chin and provide support for the head. This flexible deformation can evenly disperse the pressure of the head on the bracket 7, improving the stability and comfort of the patient's head placement.

[0043] Reference Figure 1-Figure 2 , pressure sensors are arranged on the outside of the two elastic rubber sheets 14 , and a controller is arranged inside the base 1 .

[0044] The pressure sensor and the controller are both prior art (not shown in the figure). The pressure sensor is located at the ends of the two elastic rubber sheets 14 and will not affect the use of the elastic rubber sheets 14.

[0045] When the fundus examination operation starts, the controller is started, and the control track 10 drives the slider 11 to move toward the patient's head. The plate body 16 connected to the slider 11 moves accordingly, thereby driving the elastic rubber sheet 14 to approach both sides of the patient's head.

[0046] At this time, the pressure sensor located outside the elastic rubber sheet 14 starts to work, continuously monitors the pressure data when it contacts the patient's head, and transmits these data to the controller in real time. The controller pre-sets a threshold range of appropriate pressure.

[0047] During the movement of the slider 11, the controller continuously receives data from the pressure sensor and compares it with a preset threshold value. When the pressure value detected by the pressure sensor reaches a preset suitable pressure range, the controller immediately sends a stop signal to the track 10, the track 10 stops running, and the slider 11 stops moving.

[0048] In this way, the elastic rubber sheet 14 can be fitted to both sides of the patient's head with appropriate pressure, ensuring the relative stability of the patient's head and reducing the relative position deviation between the patient's pupil and the observation window of the detector 2, while avoiding discomfort to the patient due to excessive pressure, ensuring the smooth progress of the fundus examination and improving the accuracy of the examination and the comfort of the patient.

[0049] Working principle: When the patient undergoes fundus examination, he first places his chin on the arc section of the bracket 7, and the forehead is against the positioning plate 8. The flexible material of the arc section of the bracket 7 will deform according to the shape and weight of the patient's head, evenly dispersing the pressure and providing stable and comfortable support for the head. Then, for the detector 2 in the device, the medical staff can manually push it along the slide rail 3 inside the base 1 and the slide rod 4 above according to the patient's position and examination requirements. It can remain in place when there is no external force. The medical staff can push it to the appropriate position by applying appropriate external force to overcome the friction. When the external force disappears, the detector 2 can stop immediately to ensure that its observation window is accurately aligned with the patient's pupil. Then, the electric tracks 10 on both sides drive the slider 11 to approach the patient's head, and the slider 11 drives the plate body 16 to move, so that the elastic rubber sheet 14 connected to the rod body 13 connected to the plate body 16 through the spring 12 contacts the two sides of the patient's head. The elastic rubber sheet 14 can adapt to the contour of the patient's head due to its elasticity to avoid local compression. If the patient's head moves slightly, the elastic rubber sheet 14 is squeezed and bent. Because it is rotatably connected to the rod body 13, the rod body 13 rotates accordingly, compressing the spring 12 to adapt to the change, thereby maintaining effective fixation of the patient's head, reducing involuntary movement of the head, ensuring the relative position of the pupil and the observation window of the inspection instrument is stable, and facilitating the acquisition of clear and accurate fundus images. After the inspection is completed, the track 10 drives the slider 11 to move to both sides, the spring 12 rebounds, pushing the rod body 13 to reset, and the rod body 13 drives the elastic rubber sheet 14 to restore the initial state, ready for the next use.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
