Description

Technical Field

[0001] This application relates to the field of medical assistive device technology, and in particular to an ECMO hook frame and transport device. Background Technology

[0002] In clinical practice, extracorporeal membrane oxygenation (ECMO) is used to provide continuous extracorporeal respiratory and circulatory support for critically ill patients with severe cardiopulmonary failure, thus buying precious time for emergency treatment. The core components of ECMO are the artificial lung (also known as a membrane lung or oxygenator) and the artificial heart-lung (also known as a blood pump or power pump). Due to the increasing sophistication of artificial lung and heart technologies, ECMO can be maintained for longer periods, providing the necessary foundation for its application in the treatment of cardiopulmonary failure patients. Especially for patients with severe cardiopulmonary failure, if ECMO can sustain life for several days, tens of days, or even longer, it will help save more lives.

[0003] Existing ECMO transport equipment is equipped with hooks for hanging pre-filled bags. However, these hooks are fixedly connected to the main body of the transport equipment, making it impossible for medical staff to adjust the position and angle of the hooks according to actual needs in some relatively small and complex spaces, causing inconvenience to both medical staff and patients. Summary of the Invention

[0004] Therefore, the present invention needs to provide an ECMO hook frame and transport device, which can adjust the position and angle of the hook according to actual needs to facilitate use by medical staff and patients.

[0005] An ECMO hook holder includes a hook assembly, a telescopic arm, a rotating arm, and a fixing member. The hook assembly includes an adjusting rod, a support tube, and a first hook. The adjusting rod is movably inserted into the cavity of the support tube along a first direction. The root of the first hook is fixedly connected to the top of the adjusting rod. One end of the telescopic arm is connected to the bottom of the support tube, and the other end is movably inserted into the rotating arm along a second direction. The end of the rotating arm opposite to the telescopic arm is rotatably connected to the fixing member. The rotating arm is rotatable relative to the fixing member along a third direction. The end of the fixing member opposite to the rotating arm is detachably connected to an external device. The first direction is not parallel to the second direction, and the plane containing the third direction is parallel to the second direction.

[0006] In one embodiment, the hook assembly further includes a first adjustment mechanism. The support tube has a first through hole, and the first adjustment mechanism is partially inserted through the first through hole and can abut against the outer wall of the adjustment rod to control the adjustment rod to be fixed or unfixed relative to the support tube.

[0007] In one embodiment, the telescopic arm includes a connecting hole and a movable section. The bottom of the support tube is inserted into the connecting hole to be movably connected to the telescopic arm. The rotating arm has an open section at one end facing the telescopic arm, and the movable section is movably inserted into the cavity of the open section.

[0008] In one embodiment, the hook assembly further includes a second adjustment mechanism. The telescopic arm has a second through hole, and the second adjustment mechanism is partially inserted through the second through hole and can abut against the outer wall of the portion of the support tube inserted into the connection hole, so as to control the support tube to be fixed or unfixed relative to the telescopic arm.

[0009] In one embodiment, the ECMO hook frame further includes a telescopic adjustment mechanism that passes through the opening section and the movable section, and is used to control the telescopic arm to be fixed or released relative to the rotating arm.

[0010] In one embodiment, the telescopic adjustment mechanism includes a telescopic shaft, a gear, a rack, and two knobs. The telescopic shaft passes through the axis of the gear and is movably connected to the movable section and the open section. The two knobs are respectively connected to both ends of the telescopic shaft. The rack is connected to the movable section and meshes with the gear.

[0011] In one embodiment, the telescopic adjustment mechanism further includes a flat key, which passes through the gear and is connected to the telescopic shaft. When the telescopic shaft rotates, the flat key can drive the gear to rotate synchronously.

[0012] In one embodiment, the fixing member includes a fixed connection part and a rotating connection part. The fixed connection part is screwed to an external device, and the rotating arm has a rotating part at one end facing the fixing member. The rotating connection part is rotatably connected to the rotating part.

[0013] In one embodiment, the ECMO hook frame further includes a rotation adjustment mechanism, which includes a rotating block and a locking unit. The rotating block passes sequentially through the rotating part and the rotating connecting part along its own length direction and is fixedly connected to the locking unit. The rotating part is capable of rotating about the length axis of the rotating block.

[0014] In one embodiment, the hook assembly further includes a second hook, the base of which is connected to the telescopic arm and located at the end of the support tube opposite to the first hook.

[0015] In the aforementioned ECMO hook holder, the user can adjust the angle of the first hook in a third direction by rotating the rotating arm relative to the fixing component, thereby rotating the telescopic arm, support tube, and adjusting rod. Furthermore, the user can adjust the position of the telescopic arm relative to the rotating arm, thereby moving the support tube and adjusting rod relative to the rotating arm, thus adjusting the position of the first hook in a second direction. Moreover, the user can control the position of the adjusting rod relative to the support tube to adjust the position of the first hook in a first direction. In summary, the user can adjust the position and angle of the first hook in multiple different directions, and the fixing component can be removed from the external device for independent use when needed, which improves the ease of use of the ECMO hook holder and facilitates its use by medical staff and patients.

[0016] A transfer device includes a displacement vehicle and the aforementioned ECMO hook frame, wherein the fixing element is detachably connected to the displacement vehicle. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] like Figures 1-11As shown, this application provides an ECMO hook frame 1, including a hook assembly 10, a telescopic arm 20, a rotating arm 30, and a fixing member 40. The hook assembly 10 includes an adjusting rod 110, a support tube 120, and a first hook 130. The adjusting rod 110 is positioned along a first direction (e.g., ...). Figure 1 The telescopic arm 20 is movably inserted into the cavity of the support tube 120 in any direction indicated by the T-arrow. The root of the first hook 130 is fixedly connected to the top of the adjusting rod 110. One end of the telescopic arm 20 is connected to the bottom of the support tube 120, and the other end is along the second direction (as indicated by the arrow). Figure 1 The rotating arm 30 is movably inserted in any direction indicated by the S-shaped arrow. The end of the rotating arm 30 opposite to the telescopic arm 20 is rotatably connected to the fixed member 40. The rotating arm 30 can move in any of the three directions (e.g., ...). Figure 1 The direction indicated by the U-shaped arrow (in either direction) is rotated relative to the fixed member 40. The end of the fixed member 40 facing away from the rotating arm 30 is used to connect to external equipment. The first direction is not parallel to the second direction. The plane containing the third direction is parallel to the second direction.

[0034] In the aforementioned ECMO hook holder 1, the user can adjust the angle of the first hook 130 in a third direction by rotating the rotating arm 30 relative to the fixing member 40, thereby rotating the telescopic arm 20, the support tube 120, and the adjusting rod 110. Furthermore, the user can adjust the position of the telescopic arm 20 relative to the rotating arm 30, thereby moving the support tube 120 and the adjusting rod 110 relative to the rotating arm 30, thus adjusting the position of the first hook 130 in a second direction. Moreover, the user can control the position of the adjusting rod 110 relative to the support tube 120 to adjust the position of the first hook 130 in a first direction. In summary, the user can adjust the position and angle of the first hook 130 in multiple different directions, and the user can remove the fixing member 40 from the external device for independent use when needed, which improves the ease of use of the ECMO hook holder 1 and facilitates use by medical staff and patients.

[0035] Understandably, users can set the first direction, the second direction, and the third direction according to their actual needs, as long as the first direction and the second direction are not parallel (i.e., the first direction and the second direction are set at an angle α, where 0°<α<180°), and the plane containing the third direction is parallel to the second direction.

[0036] Specifically, in this embodiment, the first direction is parallel to the vertical direction, the second direction is parallel to the horizontal direction, and the third direction is on the same plane as the second direction. This configuration is applicable to most usage scenarios, allowing adjustment of the position of the first hook 130 in the vertical direction and the position and angle of the first hook 130 in the horizontal direction.

[0037] It should be noted that when the rotating arm 30 rotates at a certain angle relative to the fixed member 40 in a third direction, the second direction will change accordingly. The second direction in this application can be regarded as the direction of the movement distance of the telescopic arm 20 relative to the rotating arm 30. When the rotating arm 30 rotates at any angle in a third direction, the second direction will also change accordingly.

[0038] It is also understandable that the outer diameter of the adjusting rod 110 should be smaller than the inner diameter of the support tube 120 so that the adjusting rod 110 can rotate and move smoothly in the inner cavity of the support tube 120.

[0039] It should also be noted that the number of first hooks 130 can be one, two, or more. When the number of first hooks 130 is greater than two, each first hook 130 can be arranged at equal angular intervals along the outer periphery of the adjusting rod 110. Specifically, in this embodiment, the number of first hooks 130 is four.

[0040] In one embodiment, such as Figures 1-4 As shown, the hook assembly 10 also includes a second hook 140. The root of the second hook 140 is connected to the telescopic arm 20 and is located at the end of the support tube 120 opposite to the first hook 130.

[0041] Therefore, in the first direction, the first hook 130 is higher than the second hook 140. The first hook 130 can be used to hang the pre-filled bag during pre-filling, allowing the saline solution in the higher bag to flow downwards under gravity, facilitating pre-filling. The second hook 140 can be used in preparation before pre-filling. Before pre-filling, saline solution is often poured into the pre-filled bag. During this process, the pre-filled bag can be hung on the second hook 140, preventing collisions and friction between the bag and other objects, effectively reducing the risk of bacteria entering the bag and causing bacterial infection to the patient.

[0042] Understandably, the number of second hooks 140 can be one, two, or more. Specifically, in this embodiment, the number of second hooks 140 is two.

[0043] It should be noted that the second hook 140 is screwed to the telescopic arm 20, and a washer 730 is provided between the two so that the second hook 140 can rotate relative to the telescopic arm 20 and the support tube 120 to adjust the angle of the second hook 140.

[0044] The second hook 140 is connected to the sleeve 230 by a screw 234, and a washer 730 is provided between them. The washer 730 distributes the pressure of the screw 234 evenly on the second through hole 232, while protecting the surfaces of the screw 234 and the second through hole 232.

[0045] A washer 141 is provided between the second hook 140 and the sleeve 230 to prevent wear between the second hook 140 and the sleeve 230.

[0046] During use, screw 234 can indirectly lock the second hook 140 onto sleeve 230 via washer 141. When external force is used to completely fit the second hook 140 and washer 141 against the lower cylindrical surface of sleeve 230, the cylindrical plane on the second hook 140 is higher than the inner cylindrical plane of sleeve 230. This height difference, when screw 234 is tightened and no external force is applied, creates a gap between the second hook 140 and sleeve 230 without it falling off sleeve 230, thus achieving the function of free rotation.

[0047] In one embodiment, such as Figures 1-4 As shown, the hook assembly 10 also includes a first adjustment mechanism 150. A first through hole 121 is provided on the support tube 120. The first adjustment mechanism 150 partially passes through the first through hole 121 and can abut against the outer wall of the adjustment rod 110 to control the adjustment rod 110 to be fixed or unfixed relative to the support tube 120.

[0048] It should be noted that users can increase the pressure between the first adjusting mechanism 150 and the outer wall of the adjusting rod 110 to increase the damping between them, thereby fixing the adjusting rod 110 to the support tube 120; conversely, users can reduce the pressure between the first adjusting mechanism 150 and the outer wall of the adjusting rod 110 to reduce the damping between them, thereby releasing the adjusting rod 110 from the support tube 120.

[0049] Furthermore, in this embodiment, the first adjustment mechanism 150 includes a knob 710, a spring 720, and a washer 730. The knob 710 passes through the spring 720 and the washer 730, extends into the first through hole 121, and abuts against the outer wall of the adjustment rod 110. During use, the user can rotate the knob 710 to control its proximity to or distance from the outer wall of the adjustment rod 110, thereby increasing or decreasing the damping between the knob 710 and the outer wall of the adjustment rod 110, and thus controlling whether the adjustment rod 110 is fixed or released relative to the support tube 120.

[0050] It should be noted that when the knob 710 is rotated to move it away from the outer wall of the adjusting rod 110, thereby reducing the damping between the knob 710 and the outer wall of the adjusting rod 110 and releasing the adjusting rod 110 from the support tube 120, the user can control the adjusting rod 110 to move up and down in the first direction to control the first hook 130 to move up and down relative to the support tube 120, thereby adjusting the height of the pre-filled bag connected to the first hook 130; alternatively, the user can rotate the adjusting rod 110 to control the first hook 130 to rotate relative to the support tube 120, thereby adjusting the angle of the pre-filled bag connected to the first hook 130.

[0051] Of course, under some extreme conditions, the adjusting rod 110 can be removed to minimize the space occupied during transportation.

[0052] In one embodiment, such as Figure 4 and Figure 7 As shown, the telescopic arm 20 includes a connecting hole 211 and a movable section 220. The bottom of the support tube 120 is inserted into the connecting hole 211 for movable connection with the telescopic arm 20. The rotating arm 30 has an open section 320 at one end facing the telescopic arm 20. The movable section 220 is movably inserted into the cavity of the open section 320.

[0053] The diameter of the connecting hole 211 should be larger than the outer diameter of the bottom of the support tube 120 so that the bottom of the support tube 120 can be movably inserted into the connecting hole 211.

[0054] It should be noted that the movable segment 220 can extend into or away from the lumen of the open segment 320 along the second direction, and the length direction of the movable segment 220 and the length direction of the open segment 320 are both parallel to the second direction.

[0055] Understandably, the outer wall dimension of the movable section 220 should be smaller than the lumen dimension of the open section 320 so that the movable section 220 can move smoothly in the lumen of the open section 320 along the second direction.

[0056] In one embodiment, such as Figures 1-4 As shown, the hook assembly 10 also includes a second adjustment mechanism 160. A second through hole 232 is provided on the telescopic arm 20. The second adjustment mechanism 160 is partially inserted through the second through hole 232 and can abut against the outer wall of the part of the support tube 120 inserted into the connection hole 211 to control the fixing or unfixing of the support tube 120 relative to the telescopic arm 20.

[0057] Furthermore, in this embodiment, the second adjustment mechanism 160 includes a knob 710, a spring 720, and a washer 730. The knob 710 passes through the spring 720 and the washer 730, extends into the second through hole 232, and abuts against the outer wall of the support tube 120. During use, the user can rotate the knob 710 to control its proximity to or distance from the outer wall of the support tube 120, thereby increasing or decreasing the damping between the knob 710 and the outer wall of the support tube 120, and thus controlling the fixation or release of the support tube 120 relative to the telescopic arm 20.

[0058] It should be noted that when the knob 710 is rotated to move it away from the outer wall of the support tube 120, thereby reducing the damping between the knob 710 and the outer wall of the support tube 120 and releasing the support tube 120 from the telescopic arm 20, the user can control the support tube 120 to move up and down in the first direction to control the first hook 130 and the second hook 140 to move up and down relative to the telescopic arm 20, thereby adjusting the height of the pre-filled bag connected to the first hook 130 and the second hook 140; alternatively, the user can rotate the support tube 120 to control the first hook 130 and the second hook 140 to rotate relative to the telescopic arm 20, thereby adjusting the angle of the pre-filled bag connected to the first hook 130 and the second hook 140.

[0059] Furthermore, such as Figure 4 As shown, in this embodiment, the telescopic arm 20 includes a main body 210 and a separation part 230. A connecting hole 211 is formed in the main body 210, and a second through hole 232 is formed in the separation part 230. Furthermore, a positioning hole 231 is also formed on the separation part 230, and the axial direction of the positioning hole 231 is consistent with the axial direction of the connecting hole 211. After the lower part of the support tube 120 passes through the connecting hole 211 and the positioning hole 231 in sequence, the knob 710 in the second adjustment mechanism 160 passes through the second through hole 232 and abuts against the outer wall of the support tube 120.

[0060] In one embodiment, such as Figure 4 As shown, the ECMO hook frame 1 also includes a telescopic adjustment mechanism 50. The telescopic adjustment mechanism 50 passes through the opening section 320 and the movable section 220, and is used to control the telescopic arm 20 to be fixed or released relative to the rotating arm 30.

[0061] It should be noted that when the telescopic adjustment mechanism 50 controls the telescopic arm 20 to be fixed relative to the rotating arm 30, the telescopic arm 20 cannot move relative to the rotating arm 30 in the second direction; when the telescopic adjustment mechanism 50 controls the telescopic arm 20 to be released from the fixed position relative to the rotating arm 30, the user can control the telescopic arm 20 to move relative to the rotating arm 30 in the second direction, thereby adjusting the position of the support tube 120, the adjusting rod 110, the first hook 130 and the second hook 140 in the second direction.

[0062] In one embodiment, such as Figure 7 , Figure 9 Hehe Figure 10 As shown, the telescopic adjustment mechanism 50 includes a telescopic shaft 510, a gear 520, a rack 530, and two knobs 710. The telescopic shaft 510 passes through the axis of the gear 520 and is movably connected to the movable section 220 and the open section 320. The two knobs 710 are respectively connected to both ends of the telescopic shaft 510. The rack 530 is connected to the movable section 220 and meshes with the gear 520.

[0063] Furthermore, such as Figure 7 and Figure 10 As shown, the telescopic adjustment mechanism 50 also includes a flat key 540, which passes through the gear 520 and is connected to the telescopic shaft 510. When the telescopic shaft 510 rotates, the flat key 540 can drive the gear 520 to rotate synchronously.

[0064] The knob 710 is locked to the telescopic shaft 510 by screws. When the knob 710 is rotated, it can drive the telescopic shaft 510 to rotate together, which in turn drives the flat key 540 on the telescopic shaft 510 to rotate. The flat key 540 can drive the gear 520 to rotate synchronously, thereby realizing the telescopic arm 20's telescopic function.

[0065] It should be noted that in actual use, the length of the movable section 220 extending into the opening section 320 can be adjusted by rotating the knob 710 in either the forward or reverse direction, thereby adjusting the position of the support tube 120, connecting rod, first hook 130, second hook 140, and pre-filled bag connected to the first hook 130 and second hook 140 in the second direction.

[0066] In one embodiment, such as Figure 8 , Figure 9 and Figure 11 As shown, the fixing member 40 includes a fixed connection portion 410 and a rotatable connection portion 420. The fixed connection portion 410 is screwed to an external device. The rotating arm 30 has a rotating portion 310 at one end facing the fixing member 40. The rotatable connection portion 420 is rotatably connected to the rotating portion 310.

[0067] It should be noted that the screws used for connecting the fixed connection part 410 to the external device can be countersunk screws 430 that can be turned by fingers, so as to avoid the use of a screwdriver and make the operation more convenient.

[0068] The fixing component 40 includes a fixed connecting part 410, a rotating connecting part 420, a countersunk screw 430, a first filling gasket 441, a second filling gasket 442, an adjusting washer 450, a wave washer 460, a screw washer 470, a locking screw 480, and a fixing connecting part 490; the fixed connecting part 410 is screwed to an external device. The rotating arm 30 has a rotating part 310 at one end facing the fixing component 40. The fixed connecting part 410 and the rotating part 310 are rotatably connected.

[0069] It should be noted that the countersunk screws used for the connection between the fixed connection part 410 and the external equipment can be M6 Phillips head countersunk screws 430, which can be tightened and loosened with a screwdriver, making the operation convenient. In addition, the locking screw 430 is an internal hex socket head cap screw.

[0070] Furthermore, the second filling gasket 442 and the wave washer 460 in the fixing member 40 serve to prevent friction, and the wave washer 460 can prevent loosening and mitigate external impacts. By adjusting the tightness of the inner locking screw 480, the rotating arm 30 can rotate in the loosened state.

[0071] Furthermore, the rotating block 610 is sequentially inserted through the rotating part 310 and the fixed connection part 410 along its own length direction, and is fixedly connected to the second filling gasket 442, the wave washer 460, the screw washer 470, and the locking screw 480. The rotating part 310 is capable of rotating about the axis of the rotating block 610 along its length direction.

[0072] In one embodiment, such as Figure 8 and Figure 11 As shown, the ECMO hook holder 1 also includes a rotation adjustment mechanism 60. The rotation adjustment mechanism 60 includes a rotating block 610 and a locking unit 620. The rotating block 610 is sequentially inserted through the rotating part 310 and the rotating connecting part 420 along its own length direction, and is fixedly connected to the locking unit 620. The rotating part 310 is capable of rotating about the longitudinal axis of the rotating block 610.

[0073] Furthermore, the locking unit 620 is provided with a screw on the side facing the rotating block 610, and the rotating block 610 is provided with a screw hole on the side facing the locking unit 620, wherein the screw is screwed into the screw hole to lock the rotating block 610.

[0074] It should be noted that when the rotating block 610 is fixed to the locking unit 620, the rotating part 310 can still rotate relative to the rotating connecting part 420. Furthermore, an isolation piece 630 is provided between the locking unit 620 and the rotating block 610 to provide isolation and reduce loosening during active operation. This application also provides a transport device (not shown in the figure), including a transport vehicle (not shown) and an ECMO hook frame 1. The ECMO hook frame 1 is detachably connected to the transport vehicle. The fixing member 40 is screwed to the transport vehicle, meaning the fixing member 40 is detachably connected to the transport vehicle. In actual use, the ECMO hook frame 1 can be connected to the transport vehicle or detached from it and connected to a portable ECMO transport frame, a transportable hospital bed, or a crane.

[0075] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0076] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0077] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0078] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
