Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a patient limb adjustment device for ultrasonic examination. Background Art
[0002] The use of coupling agent is indispensable in the limb ultrasound examination process. It can effectively reduce air interference between the probe and the skin and improve the quality of ultrasound images. However, the current examination process has obvious flaws. On the one hand, the application of coupling agent is usually a manual operation, which is not only inefficient but also difficult to ensure the uniformity of application. An uneven layer of coupling agent will lead to inconsistent attenuation of the ultrasound signal, affecting the clarity and accuracy of the image. On the other hand, after the examination, cleaning the coupling agent requires additional time and manpower, which not only prolongs the examination cycle of a single patient, but may also cause discomfort to the patient due to incomplete cleaning, and also increases the risk of cross-infection. In addition, traditional limb ultrasound examination devices are unable to closely integrate the application and cleaning of coupling agent with the examination process. Each link is independent of each other, reducing the overall examination efficiency and quality.
[0003] The patent with publication number CN117481692A discloses a patient limb adjustment device for ultrasound examination, comprising: an examination bed, a horizontal slide rail base, an electric track module, a first electric telescopic rod, a first L-shaped auxiliary bracket, a circumferential drive mechanism, and a coupling agent application mechanism. When in use, first, the patient lies flat on the upper surface of the electric track module, and the first electric telescopic rod is slid on the surface of the horizontal slide rail base so that the circular skeleton of the circumferential drive mechanism at its output end is aligned with the limb to be tested. Then, through the electric telescopic action of the first electric telescopic rod and the opposite conveying action of the electric track module, the ultrasonic detection probe and the coupling agent application mechanism on the inner side of the circular skeleton can be moved along the limb to be tested, and through the circumferential drive action of the circumferential drive mechanism, the coupling agent is evenly applied while moving and rotating, and the ultrasonic detection probe is fitted and tested in a surrounding manner.
[0004] However, the coupling agent application mechanism provided in the above technical solution is connected to the storage box, and the storage box is located in the circumferential drive mechanism. As a result, the circumferential drive mechanism limits the size of the storage box, making it impossible to pre-fill the storage box with a large amount of coupling agent. Medical staff need to add coupling agent multiple times, which is cumbersome. In addition, the coupling agent application mechanism provided in the above technical solution applies coupling agent by rolling the roller sleeve. To prevent cross-infection between patients, the roller sleeve and the gap between the roller sleeve and other components need to be thoroughly cleaned after one use, which is very inconvenient to clean.

DETAILED DESCRIPTION
[0031] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.
[0032] In the description of the present application, it should be understood that the terms "length direction", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only intended to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, features with "first", "second" can be explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.
[0033] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0034] The inventor found that the current patient limb adjusting device for ultrasonic examination has the following problems: 1. The coupling agent smearing mechanism is communicated with the storage box, and the storage box is located in the circumferential driving mechanism. In this way, the circumferential driving mechanism limits the size of the storage box, so that the storage box cannot be pre-filled with more coupling agent, and the medical staff needs to add it many times, which is cumbersome to operate; 2. The coupling agent smearing mechanism provided in the above technical solution smears the coupling agent by rolling the roller sleeve. In order to prevent cross infection between patients, the roller sleeve and the gap between the roller sleeve and other parts need to be thoroughly cleaned after each use, which is very inconvenient to clean.
[0035] Based on the above findings, the present application sets up a new patient limb adjustment device for ultrasound examination, including an examination bed board 6 and two examination mechanisms symmetrically arranged on the examination bed board 6; each group of examination mechanisms includes a movable bracket 1, a coupling agent storage box 2, an ultrasound probe holder 5, an application component 3 and a cleaning component 4; the present application, through 1. the combined design of the coupling agent storage box 2 and the application component 3, can store more coupling agent in the coupling agent storage box 2, without the need to replenish it after an ultrasound examination, greatly reducing the frequency of coupling agent replenishment and making the operation simple and convenient; 2. the combined design of the application component 3 and the cleaning component 4 can clean the coupling agent remaining on the inner wall of the application component 3 after one use so that it can be used next time to prevent cross infection between patients.
[0036] Example 1 This embodiment provides a patient limb adjustment device for ultrasound examination, such as Figure 1-21 As shown, it includes an inspection bed plate 6 and two inspection mechanisms symmetrically arranged on the inspection bed plate 6.
[0037] like Figure 1 As shown, two symmetrically arranged first rack grooves 61 are provided on the inspection bed plate 6 , and each first rack groove 61 is connected to a corresponding inspection mechanism.
[0038] like Figure 4-20 As shown, each inspection mechanism includes a mobile bracket 1, a coupling agent storage box 2, a coating component 3, a cleaning component 4 and an ultrasonic probe holder 5.
[0039] The movable bracket 1 is a columnar structure with an opening facing downward; Specifically, such as Figure 5 and 7 As shown, a first drive motor 11 is fixedly installed on the inner wall of the opening of the mobile bracket 1, and the output end of the first drive motor 11 is fixedly connected to the first drive gear 12; the first drive gear 12 is meshed with the rack in the first rack groove 61, and the side of the first drive gear 12 away from the first drive gear 12 is rotatably connected to the inner wall of the opening of the mobile bracket 1 via a rotating rod; When in use, the first drive motor 11 drives the first drive gear 12 to rotate, so that under the meshing connection between the first drive gear 12 and the rack in the first rack groove 61, the first drive gear 12 drives the movable bracket 1 to move linearly in the same direction through the rotating rod, thereby realizing the longitudinal position adjustment of the inspection mechanism on the inspection bed 6.
[0040] A first push rod 13 is fixedly provided at the upper end of the mobile bracket 1, and the movable end of the first push rod 13 is connected to the coupling agent storage box 2 after passing through the coupling agent storage box 2; a second drive motor 14 is provided above the coupling agent storage box 2, and the output end of the second drive motor 14 is rotationally connected to the output end of the first push rod 13 after passing through the coupling agent storage box 2, and the output end of the second drive motor 14 is fixedly connected to the outer wall of the coupling agent storage box 2.
[0041] During use, the first push rod 13 can drive the coupling agent storage box 2 to move up and down so as to adapt to patients of different body shapes; and the second drive motor 14 is turned on to drive the coupling agent storage box 2 to rotate so as to adjust the orientation of the coupling agent storage box 2 on the horizontal plane.
[0042] like Figure 20 and 21 As shown, the couplant storage box 2 includes a couplant storage box body 21 , a pressing plate 22 , a driving fan 23 and a plurality of first one-way valves 24 .
[0043] Specifically, the extrusion plate 22 is disposed inside the coupling agent storage box body 21, and an infusion tube 25 is provided above the extrusion plate 22. The upper end of the infusion tube 25 passes through the coupling agent storage box body 21 and is located outside. In this way, medical personnel add coupling agent through the infusion tube 25 so that the coupling agent is located between the extrusion plate 22 and the inner bottom surface of the coupling agent storage box body 21. The driving fan 23 is disposed on the top surface of the coupling agent storage box body 21 and is in communication with the interior of the coupling agent storage box body 21. Thus, the driving fan 23 can be turned on to provide a downward airflow, thereby providing a downward thrust to the extrusion plate 22, thereby pushing the extrusion plate 22 downward, thereby allowing the coupling agent to pass through a first one-way valve 24 disposed on the bottom surface of the storage box body 21 and enter the application assembly 3. The plurality of first one-way valves 24 are arranged at equal intervals on the bottom surface of the coupling agent storage box body 21 . When in use, any one of the first one-way valves 24 can be opened to allow the coupling agent to flow into the application assembly 3 .
[0044] Specifically, such as Figure 7 As shown, a mounting slot is defined on the bottom surface of the coupling agent storage box body 21, and a second push rod 15 is horizontally disposed on the sidewall of the mounting slot. The movable end of the second push rod 15 is connected to the applicator assembly 3. Thus, during use, the position of the applicator assembly 3 can be adjusted by adjusting the extension length of the second push rod 15 according to the location of the inspection site, so that the applicator assembly 3 is positioned below the corresponding first one-way valve 24, allowing the coupling agent to flow out of the first one-way valve and into the applicator assembly 3.
[0045] like Figures 8 to 19As shown, the smear assembly 3 includes a connecting tube 31, a fixed ring 32, a rotating ring 33, a movable liquid discharge head 34 and a driving module.
[0046] Among them, such as Figure 16 As shown, the rotating ring 33 is connected to the ultrasonic probe holder 5 located outside the application assembly 3 through a connecting rod 8.
[0047] like Figure 7 As shown, the connecting tube 31 is a square tubular structure. It is vertically mounted in a mounting groove on the bottom surface of the coupling agent storage box body 21 and is fixedly connected to the movable end of the second push rod 15. During use, the position of the connecting tube 31 can be adjusted by adjusting the extension length of the movable rod in the second push rod 15, so that the connecting tube 31 is located below one of the first one-way valves 24, thereby achieving lateral position adjustment of the application assembly 3.
[0048] like Figure 10 As shown, the fixing ring 32 is disposed below the connecting tube 31, and the fixing ring 32 is in communication with the connecting tube 31. An arc-shaped support plate 32b is fixedly provided on the outer surface of the fixing ring 32 for supporting the patient's limbs.
[0049] Specifically, such as Figure 13 As shown, a convex groove for mounting the rotating ring 33 is provided inside the fixed ring 32, and two annular grooves 32a are symmetrically provided on the two sides of the fixed ring 32; the cleaning assembly 4 and the driving module are respectively provided in the two annular grooves 32a; like Figure 13 As shown, one of the annular grooves 32a is further connected to a side thereof with an annular through hole 32d. The annular through hole 32 is used to accommodate the connecting rod 8 provided on the connecting ring 33, so that the connecting rod 8 on the rotating ring 33 located inside the fixed ring 32 passes through and is connected to the ultrasonic probe holder 5 located outside the fixed ring 32; the edge of the annular groove 32a is also provided with an annular through hole so that the rotating ring 33 can pass through and be connected to the driving module; Figure 11 As shown, a mounting block 32c is further provided in the annular groove 32a for connection with the driving module.
[0050] like Figure 16 As shown, the ultrasound probe holder 5 includes a connecting plate and L-shaped clips movably connected to the four sides of the connecting plate. Each L-shaped clip is connected to the connecting plate via a spring, and the bottom surface of the connecting plate is fixedly connected to the connecting rod 8. During use, the ultrasound probe can be placed at the center of the multiple L-shaped clips to clamp and secure the ultrasound probe.
[0051] like Figure 13 、 15As shown in Figures 16 and 16, the rotating ring 33 includes a first circular ring 33a and a second circular ring 33b integrally connected to the first circular ring 33a; wherein the outer diameter of the first circular ring 33a is smaller than the outer diameter of the second circular ring 33b, and the outer wall of the second circular ring 33b is in contact with the inner wall of the circular accommodating cavity of the fixed ring 32; In this way, the inner walls of the first ring 33a, the second ring 33b and the fixed ring 32 cooperate with each other to form an annular channel; the coupling agent in the connecting tube 31 is squeezed into the annular channel, and then flows out from the movable liquid outlet head 34 set on the rotating ring 33 to the patient's skin surface.
[0052] A driving ring is fixedly provided on a side of the second circular ring 33b away from the first circular ring 33a. The driving ring passes through the annular through hole of the annular groove 32a and is connected to the driving module.
[0053] The driving module includes a third driving motor 35 and a first annular rack 36 .
[0054] like Figure 16 and 19 As shown, the third drive motor 35 is fixedly mounted on the mounting block 32c, and a second drive gear 35a is provided on the output end of the third drive motor 35; The first annular rack 36 is disposed on the driving ring of the second ring 33 , and the first annular rack 36 is meshed with the second driving gear 35 a .
[0055] When in use, the third drive motor 35 is started, and the third drive motor 35 drives the second ring 33b to rotate through the second drive gear 35a, that is, the third drive motor 35 drives the rotating ring 33 to rotate as a whole through the second drive gear 35a, so as to rotate and apply coupling agent to the patient's limb.
[0056] The movable liquid outlet head 34 includes an I-shaped connecting piece 34a, a second one-way valve and a spring 34b.
[0057] The I-shaped connecting piece 34a is clamped on the side surface of the first circular ring 33a and is slidably connected to the first circular ring 33a; wherein, a through hole is provided in the center of the I-shaped connecting piece 34a, and the through hole is connected to the circular channel formed by the inner wall of the first circular ring 33a, the second circular ring 33b and the fixing ring 32, so that the coupling agent can flow out of the circular channel to the patient's skin surface.
[0058] Specifically, a second one-way valve is provided in the through hole of the I-shaped connecting piece 34a. Thus, the coupling agent is squeezed by the squeezing plate 22 and enters the through hole of the I-shaped connecting piece 34a. Then, it passes through the second one-way valve and flows out to the patient's skin surface. After the coupling agent is applied, the driving fan 23 is turned off, and the squeezing plate 22 no longer squeezes the coupling agent. At this point, the coupling agent is no longer under pressure and stops flowing out of the second one-way valve. One end of the spring 34b is fixedly connected to the I-shaped connecting piece 34a, and the other end is fixedly connected to the inner wall of the annular groove 32a. When in use, the spring 34b can provide a downward pressure on the I-shaped connecting piece 34a, so that the I-shaped connecting piece 34a is always in close contact with the patient's skin surface.
[0059] In actual use, each inspection mechanism is provided with a cleaning component 4, such as Figure 3 As shown, the cleaning assembly 4 includes two fifth drive motors 41 , two fourth drive gears 42 , two second annular racks 43 , two hanging rods 44 and a fixing cloth 45 .
[0060] The two fifth driving motors 41 , the two fourth driving gears 42 and the two second annular racks 43 are all disposed in the corresponding annular grooves 32 a .
[0061] Specifically, each fifth driving motor 41 is slidably disposed in the corresponding annular groove 32a, and the output end of the fifth driving motor 41 is fixedly connected to the corresponding fourth driving gear 42; Each hanging rod 44 is fixedly disposed on a side of the corresponding fourth driving gear 42 away from the fifth driving motor 41, and each hanging rod 44 is rotatably connected to the corresponding fourth driving gear 42; when in use, both ends of the fixing cloth 45 are respectively sleeved on the hanging rod 44; The second annular rack 43 is disposed on the side wall of the corresponding annular groove 32 a.
[0062] In this way, each fifth drive motor 41 rotates the fourth drive gear 42, which in turn meshes with the second annular rack 43, thereby moving the hanging rod 44. The hanging rod 44 then moves the fixing cloth 45, thereby cleaning the coupling agent on the side of the fixed ring 33 and the rotating ring 32 that contacts the patient's skin. In actual use, a disposable cleaning tissue can be placed on the side of the fixing cloth 45 near the fixed ring 33 and the rotating ring 32, and can be discarded after use.
[0063] In order to facilitate ultrasound examination of the patient's lower limbs, Figure 3 As shown, a second rack groove 52 is provided on the examination bed plate 6, and a lower limb position adjustment mechanism 7 is provided in the second rack groove 52. In actual use, the lower limb position adjustment mechanism 7 can be used to keep the patient's legs bent so that the area to be examined by ultrasound is exposed.
[0064] The lower limb position adjustment mechanism 7 includes two groups of lower limb adjustment components, each group of lower limb adjustment components includes a foot support plate 71, a limiting rod 72, a fourth drive motor 73 and a third push rod 74.
[0065] Specifically, grooves are provided on the two opposite side walls of the second rack groove 52, the fourth drive motor 73 is limitedly set in the groove of one of the side walls of the second rack groove 52, and the output end of the fourth drive motor 73 is connected to the third drive gear 72a; the side of the third drive gear 72a away from the fourth drive motor 73 is connected to the limiting rod 72; the end of the limiting rod 72 away from the third drive gear 72a is slidably set in the groove of the other side wall of the second rack groove 52.
[0066] When in use, the fourth drive motor 73 is turned on, and the fourth drive motor 73 drives the third drive gear 72a to rotate, and then the third drive gear 72a engages with the rack in the second rack groove 52, and the third drive gear 72a moves linearly in the second rack groove 52, and then the third drive gear 72a drives the foot support plate 71 to move linearly through the limiting rod 72.
[0067] Application Cases: Mr. Liu presented with a soft tissue mass palpable in the lower middle third of his right upper arm. The mass became more pronounced with elbow flexion, and its location shifted with elbow flexion. He was unable to actively flex his elbow, had decreased muscle strength, a loose muscle belly, and mild pain in the anterior shoulder. An upper limb ultrasound examination was performed. Step 1: The patient lies flat on the examination bed; Step 2: Start the first drive motor 11 so that the first drive motor 11 drives the movable bracket 1 to move in the first rack groove 61 through the first drive gear 12 until the movable bracket 1 is located at the lower 1 / 3 of the patient's right upper arm; Step 3: Activate the first push rod 13 so that the coupling agent storage box 2 is located above the patient; Step 4: Start the second drive motor 14 to adjust the direction of the coupling agent storage box 2; Step 5: Activate the second push rod 15 so that the application component 3 is located below the corresponding first one-way valve 24 and above the lower 1 / 3 of the patient's right upper arm; Step 6: Start the third drive motor 35, which drives the rotating ring 33 to rotate via the second drive gear 35a until the movable liquid discharge head 34 provided on the rotating ring 33 is located directly above the middle and lower 1 / 3 of the patient's right upper arm, thereby allowing the patient's right arm to pass through the fixed ring 32; Step 7: Start the driving fan 23 and the first one-way valve 24 above the connecting tube 31. The extrusion plate 22 moves downward under the action of the driving fan 23, squeezing the couplant in the couplant storage box body 21. The couplant then flows out of the first one-way valve 24 above the connecting tube 31 into the fixing ring 32. Finally, the couplant flows out of the through hole in the center of the I-shaped connecting piece 34a to the patient's part to be examined. Step 8: Turn off the driving fan 23. At this time, the extrusion plate 22 no longer presses the coupling agent downward, and the coupling agent is no longer under pressure and thus no longer flows out of the through hole in the center of the I-shaped connecting piece 34a. Step nine: Control the first driving motor 11 to move the movable bracket 11 in the opposite direction for a certain distance, so that the ultrasonic probe in the ultrasonic probe holder 5 is located on the part to be inspected for ultrasonic inspection.
[0068] After the ultrasound examination, the following steps are also included: Step 10: Hang the two ends of the fixing cloth 45 on the corresponding hanging rods 43 respectively; Step 11: Place the disposable cleaning cloth between the fixing cloth 45 and the fixing ring 32; Step 12: Start the fifth drive motor 41, which drives the fourth drive gear 42 to rotate, and then the fourth drive gear 42 cooperates with the second annular rack 43, and then the fourth drive gear 42 drives the hanging rod 43 and the fifth drive motor 41 to rotate, so as to clean the coupling agent on the surface of the fixed ring 32 and the rotating ring 33 for the next use.
