Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an ultrasound-assisted support. Background Technology

[0002] Ultrasound medicine, as an important branch of modern medical imaging technology, plays a vital role in the diagnosis and treatment of patient diseases. Ultrasound examination, as a non-invasive, convenient, and real-time medical examination method, greatly helps to promote rapid clinical diagnosis and treatment. Currently, ultrasound departments in various medical institutions are often departments with a relatively high concentration of patients and heavy examination workload, requiring both mental and physical exertion from doctors during the procedure.

[0003] During an ultrasound examination, the patient lies flat or on their side on the examination table. The doctor needs to hold the ultrasound probe and scan the corresponding examination area (such as the chest, abdomen, neck, limbs, etc.), coordinating with the pressure and movement of the probe. For key lesion areas, it is often necessary to hold the ultrasound probe firmly with pressure, or hold it in a fixed position for a longer period of time. For some particularly superficial areas, such as skin lesions, the arm also needs to be suspended in the air with coupling gel applied to maintain the suspended state, leading to arm and shoulder pain and weakness for the examining doctor, reducing examination efficiency, and in severe cases, reducing diagnostic accuracy. With the increasing number of people undergoing ultrasound examinations, ultrasound doctors have a heavy workload, repeating the above operations daily, resulting in a high incidence of occupational diseases such as cervical and lumbar spondylosis, tenosynovitis, carpal tunnel syndrome, and shoulder pain.

At least one movable joint is provided inside the support portion. The limiting device includes a controller, a first limiter, a second limiter, and a positioner. The controller is disposed on the seat plate of the seat. One end of the first limiter is inserted into the interior of the support portion, and the other end abuts against the positioning frame. One end of the positioner is inserted into the interior of the support frame, and the other end abuts against the support portion. The second limiter is located inside the support portion. The second limiter can selectively lock the movable joint.

[0006] Furthermore, the support portion includes a first support arm, a second support arm, and a third support arm; one end of the first support arm is hinged to a positioning member, and the other end is hinged to the second support arm; the end of the second support arm away from the first support arm is hinged to the third support arm; the end of the third support arm away from the second support arm is hinged to a support frame.

[0007] Furthermore, one end of the first limiter is inserted into the interior of the first support arm, and the other end abuts against the positioning frame; one end of the second limiter is inserted into the interior of the second support arm, and the other end abuts against the first support arm; one end of the positioning device is inserted into the interior of the support frame, and the other end abuts against the third support arm.

[0008] Furthermore, the limiting device also includes a third limiter; one end of the third limiter is inserted into the interior of the third support arm, and the other end abuts against the second support arm.

[0009] Furthermore, the controller is connected to the first limiter, the second limiter, and the positioner via a connecting pipe.

[0010] Furthermore, the controller includes a lifting plate, a connecting rod, a control piston, and an adjusting chamber; one end of the connecting rod is connected to the lifting plate, and the other end is inserted into the adjusting chamber and connected to the control piston; one end of the connecting pipe is connected to the adjusting chamber.

[0011] Furthermore, the adjustment chamber is equipped with a reset component inside; one end of the reset component abuts against the inner wall of the adjustment chamber, and the other end abuts against the end of the control piston away from the pull rod.

[0012] Furthermore, the first limiter includes a first limiting member and a first limiting chamber; the first limiting chamber is located inside the support portion; one end of the first limiting member abuts against the positioning frame, and the other end is inserted into the interior of the first limiting chamber; a first driving piston is fixedly connected to the end of the first limiting member inserted into the first limiting chamber; the end of the first limiting chamber away from the first limiting member is connected to a connecting pipe.

[0013] Furthermore, the first limiter, the second limiter, and the positioner have the same structure.

[0014] Furthermore, the movable joint is a ball-head joint.

[0015] The beneficial effects of this invention are as follows: When in use, the doctor sits in the chair. When the doctor leans forward, they release the controller. At this time, the first limiter, second limiter, and positioner will not lock the auxiliary device, allowing the doctor to freely adjust the shape of the auxiliary device so that the support frame is close to the patient's pre-examination area. Then, when the doctor leans back, they squeeze the controller. At this time, the first limiter, second limiter, and positioner lock the auxiliary device in place, and the support frame provides support for the doctor's arm. This saves the doctor's physical exertion during ultrasound examination. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] like Figure 1-9 The ultrasound-assisted support shown includes a seat 1, an auxiliary device 2, and a limiting device. The auxiliary device 2 includes a positioning frame 21, a support portion, and a support frame 25. One end of the auxiliary device 2 is connected to the seat 1. One end of the support portion is hinged to the positioning frame 21, and the other end is hinged to the support frame 25. The support portion has at least one movable joint inside. The limiting device includes a controller, a first limiter, a second limiter, and a positioner. The controller is mounted on the seat plate 12 of the seat 1. One end of the first limiter is inserted into the interior of the support portion, and the other end abuts against the positioning frame 21. One end of the positioner is inserted into the interior of the support frame 25, and the other end abuts against the support portion. The second limiter is located inside the support portion. The second limiter can selectively lock the movable joint.

[0032] Specifically, the seat 1 includes a backrest 11, a seat 12, armrests 14, and a support member 15; one side of the seat 12 is fixedly connected to the support member 15, and the other side is fixedly connected to the backrest 11. The support member 15 lifts the seat 12 off the ground. The armrests 14 are located on both sides of the seat 12. The positioning bracket 21 is located on one of the armrests 14.

[0033] When in use, the doctor sits in chair 1. When the doctor leans forward, they release the controller. At this time, the first limiter, second limiter, and positioner will not lock the auxiliary device 2, allowing the doctor to freely adjust the shape of the auxiliary device 2 so that the support frame 25 is close to the patient's pre-examination area. Then, the doctor leans back and squeezes the controller. At this time, the first limiter, second limiter, and positioner lock the auxiliary device 2, and the support frame 25 provides support for the doctor's arm. This saves the doctor's physical exertion during ultrasound examination.

[0034] Furthermore, the movable joint is a ball-head joint to increase the deformation range of the auxiliary device 2.

[0035] Specifically, the support includes a first support arm 22, a second support arm 23, and a third support arm 24; one end of the first support arm 22 is hinged to the positioning member 255, and the other end is hinged to the second support arm 23; the end of the second support arm 23 away from the first support arm 22 is hinged to the third support arm 24; the end of the third support arm 24 away from the second support arm 23 is hinged to the support frame 25.

[0036] One end of the positioning frame 21 is fixedly connected to the handrail 14, and the other end is fixedly connected to the first ball head.

[0037] Furthermore, the limiting device also includes a third limiter; one end of the first limiter is inserted into the interior of the first support arm 22, and the other end abuts against the positioning frame 21; one end of the second limiter is inserted into the interior of the second support arm 23, and the other end abuts against the first support arm 22; one end of the positioning device is inserted into the interior of the support frame 25, and the other end abuts against the third support arm 24. One end of the third limiter is inserted into the interior of the third support arm 24, and the other end abuts against the second support arm 23.

[0038] like Figure 4 As shown, the controller includes a lifting plate 13, a connecting rod, a control piston 17, and an adjusting chamber 16. One end of the connecting rod is connected to the lifting plate 13, and the other end is inserted into the adjusting chamber 16 and connected to the control piston 17. One end of the connecting pipe 3 is connected to the adjusting chamber 16, and the other end is connected to the first limiter, the second limiter, the third limiter, and the positioner. The control piston 17 is made of rubber or silicone. The adjusting chamber 16 is filled with liquid. When the doctor leans back, pressing the lifting plate 13 causes the control piston 17 to press down, injecting the liquid inside the adjusting chamber 16 into the first limiter, the second limiter, the third limiter, and the positioner along the connecting pipe 3.

[0039] In some embodiments of this application, a reset member is provided inside the regulating chamber 16; one end of the reset member abuts against the inner wall of the regulating chamber 16, and the other end abuts against the end of the control piston 17 away from the pull rod. When the doctor leans back, pressing the lifting plate 13 causes the control piston 17 to press down, compressing the reset member. When the doctor leans forward, the reset member causes the control piston 17 to rise, drawing the liquid inside the first limiter, second limiter, third limiter, and positioner back into the regulating chamber 16 along the connecting pipe 3.

[0040] Specifically, the reset component is a spring.

[0041] like Figure 5 As shown, the first support arm 22 includes a first storage rod 221, a first telescopic rod 223, and a first joint sleeve 225. One end of the first telescopic rod 223 is inserted into the interior of the first storage rod 221, and the other end is fixedly connected to a second ball head. The end of the first storage rod 221 away from the first telescopic rod 223 is fixedly connected to the first joint sleeve 225. The first joint sleeve 225 covers the outside of the first ball head. A first limiter is located at the end of the first storage rod 221 away from the first telescopic rod 223. The end of the first joint sleeve 225 away from the first storage rod 221 has a first opening. The diameter of the first opening is smaller than the diameter of the first ball head to prevent the first ball head from disengaging from the first joint sleeve 225.

[0042] Furthermore, the first support arm 22 includes a first adjusting member; the first adjusting member passes through the first storage rod 221 and abuts against the first telescopic rod 223. The first adjusting member is threadedly connected to the first storage rod 221. When in use, tightening the first adjusting member locks the total length of the first storage rod 221 and the first telescopic rod 223, thereby allowing adjustment of the length of the first support arm 22.

[0043] The first limiter includes a first limiting member 222 and a first limiting chamber 224; the first limiting chamber 224 is located inside the first receiving rod 221; one end of the first limiting member 222 abuts against the positioning frame 21, and the other end is inserted into the first limiting chamber 224. A first driving piston is fixedly connected to the end of the first limiting member 222 inserted into the first limiting chamber 224. The end of the first limiting chamber 224 away from the first limiting member 222 is connected to the connecting pipe 3. When the liquid inside the regulating chamber 16 is injected into the first limiting chamber 224 along the connecting pipe 3, it drives the first driving piston to move towards the first joint sleeve 225, causing the first limiting member 222 to press against the side wall of the first ball head, thus increasing the friction between the first limiting member 222 and the first ball head, thereby locking the relative position of the first limiting member 222 and the first ball head, and locking the angle between the first support arm 22 and the positioning frame 21.

[0044] like Figure 4-5As shown, the first limiter, second limiter, and third limiter have the same structure as the positioner. The first support arm 22, second support arm 23, and third support arm 24 have the same structure.

[0045] The second support arm 23 includes a second storage rod, a second telescopic rod, and a second joint sleeve. One end of the second telescopic rod is inserted into the interior of the second storage rod, and the other end is fixedly connected to a third ball head. The end of the second storage rod away from the second telescopic rod is fixedly connected to the second joint sleeve. The second joint sleeve covers the outside of the second ball head. A second limiter is located at the end of the second storage rod away from the second telescopic rod. The end of the second joint sleeve away from the second storage rod has a second opening. The diameter of the second opening is smaller than the diameter of the second ball head to prevent the second ball head from disengaging from the second joint sleeve.

[0046] Furthermore, the second support arm 23 includes a second adjusting member; the second adjusting member passes through the second storage rod and abuts against the second telescopic rod. The second adjusting member is threadedly connected to the second storage rod. When in use, tightening the second adjusting member locks the total length of the second storage rod and the second telescopic rod, thereby allowing adjustment of the length of the second support arm 23.

[0047] The second limiter includes a second limiting member and a second limiting chamber; the second limiting chamber is located inside the second receiving rod; one end of the second limiting member abuts against the second ball head, and the other end is inserted into the interior of the second limiting chamber. A second driving piston is fixedly connected to the end of the second limiting member inserted into the second limiting chamber. The end of the second limiting chamber away from the second limiting member is connected to the connecting pipe 3. When liquid inside the regulating chamber 16 is injected into the second limiting chamber along the connecting pipe 3, it drives the second driving piston to move towards the second joint sleeve, causing the second limiting member to press against the side wall of the second ball head, thus increasing the friction between the second limiting member and the second ball head to lock the relative position of the second limiting member and the second ball head, thereby locking the angle between the second support arm 23 and the first support arm 22.

[0048] The third support arm 24 includes a third storage rod, a third telescopic rod, and a third joint sleeve. One end of the third telescopic rod is inserted into the interior of the third storage rod, and the other end is fixedly connected to a fourth ball head. The end of the third storage rod away from the third telescopic rod is fixedly connected to the third joint sleeve. The third joint sleeve covers the outside of the third ball head. A third limiter is located at the end of the third storage rod away from the third telescopic rod. The end of the third joint sleeve away from the third storage rod has a third opening. The diameter of the third opening is smaller than the diameter of the third ball head to prevent the third ball head from detaching from the third joint sleeve.

[0049] Furthermore, the third support arm 24 includes a third adjusting member; the third adjusting member passes through the third storage rod and abuts against the third telescopic rod. The third adjusting member is threadedly connected to the third storage rod. When in use, tightening the third adjusting member locks the total length of the third storage rod and the third telescopic rod, thereby allowing adjustment of the length of the third support arm 24.

[0050] The third limiter includes a third limiting member and a third limiting chamber; the third limiting chamber is located inside the third receiving rod; one end of the third limiting member abuts against the third ball head, and the other end is inserted into the interior of the third limiting chamber. A third driving piston is fixedly connected to the end of the third limiting member inserted into the third limiting chamber. The end of the third limiting chamber away from the third limiting member is connected to the connecting pipe 3. When liquid inside the regulating chamber 16 is injected into the third limiting chamber along the connecting pipe 3, it drives the third driving piston to move towards the third joint sleeve, causing the third limiting member to press against the side wall of the third ball head, thus increasing the friction between the third limiting member and the third ball head to lock the relative position of the third limiting member and the third ball head, thereby locking the angle between the third support arm 24 and the second support arm 23.

[0051] like Figure 6-9 As shown, the support frame 25 includes an arm support 251, an adjusting plate 252, a fourth joint sleeve 253, and a fourth adjusting member 256. One end of the arm support 251 is fixedly connected to the fourth joint sleeve 253, and the other end is slidably connected to the adjusting plate 252. The adjusting plates 252 are located on both sides between the arms. One end of the adjusting plate 252 is inserted into the arm support 251. The fourth adjusting member 256 passes through the arm support 251 and abuts against the adjusting plate 252. The fourth adjusting member 256 is threadedly connected to the arm support 251. The fourth joint sleeve 253 covers the outside of the fourth ball head. The locator is located at the end of the arm support 251 away from the adjusting plate 252. The end of the fourth joint sleeve 253 away from the fourth storage rod has a fourth opening. The diameter of the fourth opening is smaller than the diameter of the fourth ball head to prevent the fourth ball head from disengaging from the fourth joint sleeve 253.

[0052] The positioner includes a fourth limiting member and a fourth limiting chamber; the fourth limiting chamber is located inside the arm support 251; one end of the fourth limiting member abuts against the fourth ball head, and the other end is inserted into the interior of the fourth limiting chamber. A fourth driving piston is fixedly connected to the end of the fourth limiting member inserted into the fourth limiting chamber. The end of the fourth limiting chamber away from the fourth limiting member is connected to the connecting pipe 3. When liquid inside the regulating chamber 16 is injected into the fourth limiting chamber along the connecting pipe 3, it drives the fourth driving piston to move towards the fourth joint sleeve 253, causing the fourth limiting member to press against the side wall of the fourth ball head, thus increasing the friction between the fourth limiting member and the fourth ball head to lock the relative position of the fourth limiting member and the fourth ball head, thereby locking the angle between the support frame 25 and the third support arm 24.

[0053] How to use this embodiment:

[0054] 1. Adjust the lengths of the first support arm 22, the second support arm 23, and the third support arm 24 according to the doctor's body shape;

[0055] 2. The doctor sits in chair 1;

[0056] 3. When the doctor leans forward and moves away from the controller, the reset component drives the control piston 17 to rise, drawing the liquid inside the first limiter, second limiter, third limiter, and positioner back into the regulating chamber 16 along the connecting pipe 3; thus preventing the first limiter, second limiter, third limiter, and positioner from locking the auxiliary device 2.
