Description

Technical Field

[0001] The present invention relates to the technical field of medical image reading and display, and in particular to a medical image reading and display device for neurological diagnosis. Background Art

[0002] Medical imaging technology is an important means of modern medical diagnosis. It can obtain images of internal tissues of the human body or a part of the human body in a non-invasive way. It plays an irreplaceable role in early detection, precise treatment and disease monitoring of diseases. In the diagnosis of neurological diseases, medical imaging examinations are intuitive, specific and quantitative. They can directly display the structure and function of the brain and provide doctors with a visual basis for diagnosis.

[0003] With the continuous advancement of medical technology, the types of medical images are becoming increasingly rich, including X-ray, CT (computed tomography), MRI (magnetic resonance imaging) and other imaging methods. Among them, X-ray can be used to diagnose skull fractures, intracranial tumors and other space-occupying lesions, as well as spinal fractures, intervertebral disc herniation and other lesions in the diagnosis of neurological diseases; CT can be used to diagnose cerebral hemorrhage, cerebral infarction, intracranial tumors and other lesions in the diagnosis of neurological diseases, as well as to evaluate vascular lesions such as cerebral vascular stenosis and aneurysm; MRI can be used to diagnose inflammatory and degenerative diseases such as encephalitis, meningitis, Parkinson's disease, Alzheimer's disease, and the activity of the cerebral cortex and the evaluation of nerve fiber connections in the diagnosis of neurological diseases. The medical image reading device mainly places the image film on the reading device, and through the form of light illumination, the light is irradiated onto the light film through the light-transmitting plate, so that the light film image data presents the image of the internal tissue of the human body, so that medical staff can observe the patient's image, thereby helping the patient to see the cause of their disease and the location of the lesion.

[0004] At present, the main means of reading medical images include direct handheld reading and display device-assisted reading. Among them, handheld reading means that medical staff hold the optical film and place it under a specific light when reading medical images, so as to carefully observe the image details. This method not only increases the workload of medical staff, but also easily causes wrist soreness after long-term operation, affecting work efficiency and diagnosis quality. In addition, handheld reading is difficult to ensure the stability of the optical film. The optical film may become blurred due to slight movements of the hand, affecting the observation effect and not conducive to medical staff explaining and illustrating the patient's condition. The existing display devices are mostly vertical insert-type display devices. Although they reduce the burden of handheld reading for medical staff to a certain extent, the vertical insertion of this type of display device is prone to physical damage to the optical film. Specifically, when the optical film is inserted vertically, the edge of the optical film is unevenly stressed and is prone to bending, curling or even falling, which not only affects the clarity of the image, but may also cause permanent damage to the image film, bringing inconvenience to subsequent observation and analysis. Summary of the invention

[0005] The present invention is intended to provide a medical image reading and display device for neurological diagnosis, which is connected to a storage cabinet through a lifting assembly on a base to adjust the height of the entire display device; the display frame is connected to a connecting tube with an inner spline portion on the storage cabinet through a connecting shaft with an outer spline, and the angle of the display frame can be adjusted by adjusting the spline connection relationship between the connecting shaft and the connecting tube, and the placement frame for placing the optical film is slidably connected to the display frame, and the display frame is adjusted to a horizontal state to place the optical film, which can effectively prevent the optical film from bending, curling or even falling when the optical film is placed. In the process of reading the film, the different angles of the display frame are adjusted again, which is convenient for medical staff to read the film and explain and illustrate to the patient. The problem in the background technology is solved.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore, the lifting device includes a lower externally threaded rod, an internally threaded tube and an upper externally threaded rod, the upper externally threaded rod and the lower externally threaded rod are respectively connected to the upper and lower sides of the internally threaded tube by threads, and the threads of the upper externally threaded rod and the lower externally threaded rod have opposite rotation directions; the free end of the upper externally threaded rod is fixedly connected to the locker, and the free end of the lower externally threaded rod is fixedly connected to the base.

[0009] Furthermore, a spring is sleeved on the outer side of the connecting shaft, and both ends of the spring are respectively connected to the end surface of the external spline and the inner end surface of the connecting tube, and the free length of the spring is not shorter than the length of the blank portion.

[0010] Furthermore, the free length of the spring is equal to the length of the blank portion, and the major diameter of the spring is equal to the inner diameter of the connecting tube; and the display frame is connected to a first handle on a side away from the connecting axis.

[0011] Furthermore, the limiting locking piece is an eccentric circular piece, the limiting locking piece is connected to a second handle rotatably connected to the placement frame, and the second handle is arranged on the outside of the placement frame.

[0012] Furthermore, the outer sides of the internal threaded cylinder, the first handle and the second handle are all sleeved with anti-slip sleeves.

[0013] Furthermore, the display frame and the placement frame are both hollow in the middle and are both ring-shaped.

[0014] Furthermore, fill lights are connected around the inner ring of the display frame, and four of the fill lights are connected in parallel.

[0015] Furthermore, the left and right inner walls of the display frame are provided with "convex" shaped limiting guide grooves, and the left and right outer walls of the placement frame are connected with protrusions, which are slidably arranged on the inner sides of the limiting guide grooves.

[0016] Furthermore, a flashlight, a laser pen and a magnifying glass are placed inside the locker.

[0017] The principle and beneficial effects of the technical solution are:

[0018] 1. A medical image reading and display device for neurological diagnosis provided by the present invention is connected to a storage cabinet through a lifting assembly on a base. Medical staff can adjust the height of the entire display device according to actual conditions to facilitate the comfort of the reading process and the accuracy of the reading information; the display frame is connected to a connecting tube with an inner spline portion on the storage cabinet through a connecting shaft with an outer spline, and the angle of the display frame can be adjusted by adjusting the connection relationship of the splines between the connecting shaft and the connecting tube. Specifically, when the display frame is pulled outward so that the outer spline on the connecting shaft is disengaged from the meshing with the inner spline portion of the connecting tube, the display frame can be arbitrarily rotated with the connecting shaft as the axis to adjust its angle, and when the display frame is pushed inward so that the outer spline on the connecting shaft is disengaged from the meshing with the inner spline portion of the connecting tube, the display frame can be rotated arbitrarily with the connecting shaft as the axis to adjust its angle. The inner spline parts of the connecting tube mesh with each other, and the display frame is locked and cannot rotate; the placement frame for placing the optical film is slidably connected to the display frame, and the optical film is placed in the placement frame after the display frame is adjusted to a horizontal state, which can effectively prevent the optical film from being bent, curled or even falling when the optical film is placed, thereby ensuring the clarity of the optical film. During the film reading process, the different angles of the display frame are adjusted again to achieve multi-angle film reading, further ensuring the accuracy of film reading, and the limit lock piece locks the placement frame and the display frame to prevent the placement frame from sliding during the rotation process, causing the optical film to slip out; similarly, by adjusting the height and / or angle of the display device, it is also convenient for medical staff to explain and illustrate the patient's condition based on the optical film;

[0019] 2. The present invention provides a medical image reading and display device for neurological diagnosis. The lifting device adopts an external threaded rod with opposite thread rotation directions connected to the two ends of the internal thread. The internal threaded cylinder is rotated, and the upper and lower external threaded rods are moved towards each other (moving away from each other or approaching each other) under the action of the thread, so as to adjust the height of the whole device. The adjustment is convenient and quick. In addition, by fixing the internal threaded cylinder and rotating the upper external threaded rod, the angle of the storage cabinet connected to the display frame can also be adjusted. That is, the display device can not only adjust the horizontal angle during the reading process along the horizontally arranged connecting shaft, but also adjust the vertical angle during the reading process along the vertically arranged internal threaded cylinder, so as to further improve the accuracy of the reading.

[0020] 3. A medical image reading and display device for neurological diagnosis provided by the present invention has a spring on the outer side of the connecting shaft, and the two ends of the spring are respectively connected to the outer spline end face of the connecting shaft and the end face of the connecting tube. The length of the spring is not shorter than / equal to the length of the blank part, so that the outer spline of the connecting shaft is always engaged with the inner spline of the connecting tube under the action of the spring, ensuring the stability of the display device during the reading process, so as to facilitate the reading of the film. By pulling the display frame to overcome the action of the spring, the outer spline of the connecting shaft is in the blank part of the connecting tube (the outer spline and the inner spline are completely separated), and the display frame can be rotated at will to ensure The angle adjustment functionality of the device is improved. The first handle connected to the display frame is convenient for applying pulling force and / or pushing force to the display frame, thereby improving the convenience of operation. Similarly, the second handle connected to the placement frame is also beneficial for pulling the placement frame out and / or pushing the placement frame into the display frame.
