Technical Field
[0001] The invention relates to the technical field of ultrasonic diagnosis, in particular to an auxiliary device for diagnosing lymph node tuberculosis by combining ultrasonic contrast imaging with elastic imaging. Background Art
[0002] Tuberculosis is a chronic infectious disease caused by infection with Mycobacterium tuberculosis. Normal lymph nodes are composed of capsule, parenchyma, and medulla. The capsule is mostly manifested as linear high echoes on ultrasound. When normal lymph nodes are invaded by Mycobacterium tuberculosis, it can cause varying degrees of damage to the lymph node cortex and medulla and edema and inflammatory infiltration of surrounding tissues. Due to the formation of tuberculous granulomas and caseous necrosis, there will be a variety of different imaging changes at different stages and periods. It is chronic and long-lasting, seriously affecting human health and quality of life. It is currently a hot spot and difficulty in the diagnosis and treatment of extrapulmonary tuberculosis. With the application of new ultrasound technologies - elastic imaging and ultrasound angiography, the diagnosis and treatment of superficial lymph node lesions have received increasing attention. The human body's lymph nodes are mostly distributed in the neck, so ultrasound angiography and elastic imaging of the cervical lymph are necessary steps in the diagnosis of lymph node tuberculosis.
[0003] However, in actual use, because the human neck is located between the head and the torso and has a relatively rugged contour, the doctor needs to exert special force to make the ultrasound probe fit for detection. The doctor's force will cause the doctor's attention to be distracted, making it difficult to observe the test results attentively, thereby prolonging the test time and reducing the accuracy of the test results. Therefore, an auxiliary device for diagnosing lymph node tuberculosis by combining ultrasound contrast imaging with elastic imaging is developed. Summary of the invention

[0024] Tuberculosis is a chronic infectious disease caused by infection with Mycobacterium tuberculosis. Normal lymph nodes are composed of capsule, parenchyma, and medulla. The capsule is mostly manifested as linear high echoes on ultrasound. When normal lymph nodes are invaded by Mycobacterium tuberculosis, it can cause varying degrees of damage to the lymph node cortex and medulla and edema and inflammatory infiltration of surrounding tissues. Due to the formation of tuberculous granulomas and caseous necrosis, there will be a variety of different imaging changes at different stages and periods. It is chronic and long-lasting, seriously affecting human health and quality of life. It is currently a hot spot and difficulty in the diagnosis and treatment of extrapulmonary tuberculosis. With the application of new ultrasound technologies - elastic imaging and ultrasound angiography, the diagnosis and treatment of superficial lymph node lesions have received increasing attention. The human body's lymph nodes are mostly distributed in the neck, so ultrasound angiography and elastic imaging of the cervical lymph are necessary steps in the diagnosis of lymph node tuberculosis.
[0025] However, in actual use, because the human neck is located between the head and the torso and has a relatively rugged contour, the doctor needs to exert special force to make the ultrasound probe fit for detection. The doctor's force will cause the doctor's attention to be distracted, making it difficult to observe the test results attentively, thereby prolonging the test time and reducing the accuracy of the test results. Therefore, an auxiliary device for diagnosing lymph node tuberculosis by combining ultrasound contrast imaging with elastic imaging is developed. Figure 1-Figure 5 The device includes a support system 4, wherein an auxiliary bed 1 is fixedly connected to the top of the support system 4, a diagnostic auxiliary device 2 is arranged on the top side of one end of the auxiliary bed 1, and a bending hydraulic press 3 is fixedly connected to one side of the support system 4, the output end of the bending hydraulic press 3 is a rotatable telescopic tube, one end of the telescopic tube is rotatably connected to one side of the bending backrest 101 in the auxiliary bed 1.
[0026] like Figure 3 and Figure 4As shown, the diagnostic auxiliary device 2 includes a connecting bracket 203, and the upper and lower sides of one end of the connecting bracket 203 are respectively fixedly connected with a bracket plate, and the two sides of one end of each bracket plate are respectively rotatably connected with a rotating shaft. In this embodiment, the two rotating shafts are not connected, so a certain space is left in the middle, and the upper and lower ends of each rotating shaft are respectively fixedly connected with a rotating fixing frame 206. In this embodiment, the rotating fixing frame 206 is semicircular and can be opened and closed by rotating, so that it is more convenient to put it on the patient's neck. Therefore, the circular frame surrounded by the rotating fixing frames 206 on both sides needs to have a larger diameter to avoid too tight fitting to restrict the user's normal breathing, and also make the patient more comfortable to wear. One end of the four rotating fixing frames 206 on the same side is fixedly connected to a connecting plate, so there are two connecting plates in total, and the two connecting plates correspond to each other. It should be noted that the two connecting plates do not completely cover one end of the four rotating fixing frames 206, but leave a certain space on the outer part. In this embodiment, the two connecting plates can be fixed to each other, such as by setting a buckle, or using a magnetic material as the raw material, or by setting an adhesive device on the contact surface of the two connecting plates, so as to splice the rotating fixing frames 206 on both sides into a complete annular frame. The outer sides of the rotating fixed frames 206 on both sides are slidably connected to a surrounding device 201, and the surrounding device 201 includes a card sleeve frame 211. In this embodiment, there is a hole in the middle of the card sleeve frame 211, so that medical staff can pass the probe used for ultrasonic angiography and elastic imaging through the card sleeve frame 211 and contact the patient's neck skin. A driving chamber 214 is integrally formed on both sides of the card sleeve frame 211, and a driving motor is fixedly connected to the inner side of each driving chamber 214, and a surrounding wheel 212 is rotatably connected to the upper and lower sides, and each group of two surrounding wheels 212 The two drive motors are driven by a driving motor respectively. In this embodiment, the two drive motors are controlled by the signal of the same control source, so the two drive motors have the same operating rules and can perform substantially synchronous motion to drive the four surrounding wheels 212 to rotate, and the inner side of each surrounding wheel 212 is respectively connected to the inner wall relative to a group of connecting brackets 203, thereby driving the surrounding device 201 to move on the annular frame surrounded by the rotating fixed frames 206 on both sides. Because the outer side of the connecting plate leaves space, the surrounding device 201 can cross the relatively narrow seam between the two rotating fixed frames 206. At the same time, in this embodiment, the control source of the driving motor can be integrated into the control panel of the ultrasound angiography and elastic imaging system, so that the doctor does not have to take out one hand to hold the ultrasound probe all the time, and the doctor can always maintain a more comfortable sitting posture for diagnosis, and can also control the position of the ultrasound probe. A storage groove is respectively opened on both sides of the inner wall of the card sleeve frame 211, and a fastening buckle 213 is fixedly connected to one side of the inner wall surrounding each storage groove through a spring.In this embodiment, the two sides of the fastening buckle 213 are provided with inclined surfaces, so that the fastening buckle 213 forms a trapezoid, so that the ultrasonic probe can be squeezed to retract the fastening buckle 213 regardless of whether it is inserted or not, and then reset. After the ultrasonic probe is inserted, the reset squeezing fastening buckle 213 will clamp the thinner handle of the ultrasonic probe to fix it. The opposite sides of each set of two rotating fixing frames 206 located on the same rotating axis are directly and commonly fixedly connected with an inflatable squeezing airbag 205, and the inner side is commonly fixedly connected with an elastic coating liquid annular box 202. In this embodiment, the inner side of the coating ring box 202 is provided with a plurality of liquid outlet holes, which are in contact with the patient's skin, and the box is filled with a loose porous adsorbent, such as a sponge, etc., and filled with a medical coupling agent for ultrasound examination, and it is ensured that the medical coupling agent in the adsorbent will not seep out through the liquid outlet holes in large quantities without being acted upon by external forces, and the outer side of the squeezing airbag 205 is also made of a hard material, and the side close to the coating ring box 202 is made of a retractable material, so when the squeezing airbag 205 is inflated to expand, the adsorbent material in the coating ring box 202 is squeezed, so that the medical coupling agent therein is squeezed out and applied to the patient's neck, so that the ultrasound probe slides more smoothly on the skin and the imaging is more accurate. At the same time, the coating ring box 202 can be removed, and a feeding port is opened on one side of the upper and lower sides thereof to facilitate the filling of the medical coupling agent into the box. At the same time, an air filling tube 204 is fixedly arranged on one side of each extrusion airbag 205, and the outer ends of the two air filling tubes 204 on the same side are connected to a single-side collecting tube, and the bottom ends of the two single-side collecting tubes are connected to an air pump connecting tube 207. The air pump connecting tube 207 is connected to an air pump to inflate the extrusion airbag 205 to make it expand evenly, so that the medical coupling agent can be evenly applied.
[0027] like Figure 2 As shown, the auxiliary bed 1 includes a horizontal bed body 103, one end of the horizontal bed body 103 is rotatably connected to a folding backrest 101, and the top of the folding backrest 101 is rotatably connected to a folding pillow 102. In this embodiment, the folding backrest 101, the horizontal bed body 103 and the folding pillow 102 are all covered with cushions, so that the patient can lie comfortably. In this embodiment, the patient's legs and buttocks are placed on the horizontal bed body 103, the back is leaning on the folding backrest 101, and the head is leaning on the folding pillow 102. At the same time, the bending joints between the three are usually locked, and human power is required to release the joints before they can rotate, thereby ensuring the stability of the auxiliary bed 1. At the same time, a connecting rod is provided between the folding pillow 102 and the folding backrest 101, and one side of the connecting rod is rotatably connected to the connecting bracket 203. Thus, the angle of the diagnosis auxiliary device 2 can be adjusted.
[0028] like Figure 5As shown, the support system 4 includes a support base 403, the top of which is fixedly connected to a horizontal bed board 402, the top of which is slidably connected to the horizontal bed body 103, and one side of which is fixedly connected to a foot support board 401. When the patient is using it, the sole of his foot should be against the foot support board 401. If the patient's legs cannot be straightened, the auxiliary bed 1 is driven to slide backward by force to ensure the patient's comfort. At the same time, a bending hydraulic press 3 is fixedly connected to one side of the support base 403, and the output end of the bending hydraulic press 3 is rotatably connected to one side of the bending backrest 101. Thus, the bending backrest 101 is lifted by the operation of the bending hydraulic press 3.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
