Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a liftable and weighable footstool for use in interventional rooms. Background Technology
[0002] During interventional procedures in hospitals, patients often need a footstool to get on and off the operating table due to its height. For example, a Chinese utility model patent with publication number CN213788572U and patent name "A Multifunctional Footstool for Operating Table" includes a main structure, a height adjustment structure, a weighing structure, and an armrest structure. One side of the main structure is detachably connected to the height adjustment structure, one side of the weighing structure is detachably connected to the main structure, and one side of the armrest structure is detachably connected to the weighing structure. The outer surface of the main structure is equipped with locking casters to facilitate the movement of the device.
[0003] During operation, the device is locked in place on the patient by the casters. The height adjustment mechanism includes a servo motor, a jack, and a control foot pedal. The main structure includes a support plate and a main shelf. The servo motor drives the threaded horizontal shaft of the jack to rotate, increasing the distance between the support plate and the main shelf, thus raising the height of the device to facilitate use by shorter patients. The weighing mechanism measures the patient's weight for easier medication dispensing. The handrail mechanism includes a steel pipe, a button, and a spring. Medical staff can adjust the handrail's height within the main shelf to allow taller patients to hold onto the foam handrail, reducing the risk of falls when getting out of bed.
[0004] However, the existing technology still has the following drawbacks: the main structure, height adjustment structure, and armrest structure of the existing medical footrest are relatively complex, which increases the production and manufacturing cost of the footrest and makes it difficult to promote in the market; in addition, the medical footrest needs to be equipped with at least two sets of height adjustment structures, and each set of height adjustment structures needs to be controlled by a servo motor to adjust the height of the jack, which further increases the production and manufacturing cost of the medical footrest, and the complex height adjustment design makes it inconvenient for medical staff to operate and affects the patient's user experience. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a liftable and weighable footstool for use in intervention rooms.
[0006] The objective of this utility model is achieved through the following technical solution: a liftable and weighable footstool for an interventional room, comprising a base, a foot cover, a guide assembly, and a lifting system. The foot cover has a cover plate and a lower extension plate integrally extending vertically downward around the cover plate. The cover plate is disposed above the base and is movably covered on the upper end of the base via the lower extension plate. The guide assembly is vertically positioned between the base and the foot cover, and the cover plate and / or the lower extension plate are movably connected to the base via the guide assembly. The lifting system has a driver and a lifting foot pedal. The driver is disposed within the base and connected to the foot cover, and is used to connect to and control the driver to drive the foot cover to move up and down on the base along the direction of the guide assembly via the lifting foot pedal.
[0007] Furthermore, the guide assembly has a guide groove and a guide rod. The guide groove is disposed on the outer surface of the base, and the guide rod is disposed on the inner surface of the lower extension plate of the foot cover, so that when the foot cover is placed over the upper end of the base, its lower extension plate is movably connected to the base through the cooperation of the guide rod and the guide groove.
[0008] Furthermore, the guide assembly has a sleeve and a slide rod. The sleeve is disposed within the base, the lower end of the slide rod is movably disposed within the sleeve, and the upper end of the slide rod is fixedly connected to the cover plate of the foot cover.
[0009] Furthermore, the base is provided with an upward-opening cavity, the driver is disposed in the cavity, and the driver's drive rod is connected to and drives the cover plate to move vertically up and down.
[0010] Furthermore, a foot pedal hole communicating with the cavity is provided on one side of the base, and the lifting foot pedal is correspondingly disposed in the foot pedal hole, and an anti-slip layer is provided on the upper surface of the lifting foot pedal.
[0011] Furthermore, the liftable weight-bearing footstool also includes a pull rod assembly, which has a groove plate and a handle. The groove plate is disposed on the base, and the upper end of the groove plate passes through the cover plate and exposes the upper surface of the cover plate. The handle has a pull rod and is movably connected to the groove plate through the pull rod. The handle is provided with a tension button for adjusting the sliding position of the pull rod on the groove plate.
[0012] Furthermore, the highest lifting height of the foot cover when the base is raised is less than the lowest assembly height of the handle when the base is lowered.
[0013] Furthermore, the liftable and weighable footstool also includes a weighing module, which is disposed on the cover plate and has a display for displaying the patient's weight.
[0014] Furthermore, the weighing error of the weighing module is set within the range of ±0.1 kg.
[0015] Furthermore, the bottom of the base is provided with casters and casters, which are respectively located at two corners at both ends of the base.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] The structural design of the base, footrest, and lifting system of the adjustable weighing footrest provided in this application embodiment is very simple, which facilitates mold making and production, reduces manufacturing costs, and is conducive to market promotion. The footrest can be raised and lowered on the base by simply using the lifting foot pedal control driver arranged at the footrest hole. Compared with the complicated method of adjusting the height of the footrest by controlling the jack with the servo motor of the previous medical footrest, the lifting design of the footrest using the lifting foot pedal control driver in this application is simpler and more convenient, further reducing the manufacturing cost of the footrest, making it easier for medical staff to use and operate, and improving the user experience for patients. Moreover, when assembling the footrest and the base, a guide component is assembled between the lower extension plate and the base. Driven by the driver, the footrest can be stably raised and lowered on the base along the guide component, improving the lifting stability of the footrest. In addition, the cover fit between the lower extension plate of the footrest and the upper end of the base further improves the structural strength of the assembly between the footrest and the base.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0036] First Embodiment
[0037] like Figure 1-6 As shown, a liftable weighable footstool for use in an interventional room includes a base 10, a foot cover 20, a guide assembly 30, a lifting system 40, a pull rod assembly 50, and a weighing module 60. The base 10 is provided with an upward-opening cavity 101, and a foot pedal hole 102 is provided on any side of the base 10. The cavity 101 can be used to install the lifting system 40 and other module components.
[0038] The lifting system 40 includes a driver 401 and a lifting foot pedal 402. The driver 401 is installed in the middle of the cavity 101 of the base 10, and can be either a hydraulic cylinder or a pneumatic cylinder. The lifting foot pedal 402 is connected to the driver 401 and is also installed inside the cavity 101 of the base 10. The lifting foot pedal 402 is also provided with a foot pedal hole 102 on the base 10. In use, medical personnel can insert their feet into the foot pedal hole 102 to step on the lifting foot pedal 402 to control the action of the driver 401.
[0039] Specifically, for example, when a patient needs to use a footstool to get onto the operating table, and when the actuator 401 uses the hydraulic cylinder, the patient can first stand on the footrest 20 that has not yet been raised and hold on, and then the medical staff can step on the lifting foot pedal 402. At this time, the lifting foot pedal 402 can be regarded as a reversing valve switch, so that when the lifting foot pedal 402 is stepped on, the oil circuit on the right side of the oil tank is connected to the oil cylinder, the oil inlet on the right side of the oil cylinder is the oil return port, the piston in the pump is pushed, the hydraulic oil in the pump is drawn into the oil cylinder and compressed, generating pressure, which in turn causes the push rod of the oil cylinder to rise and push the footrest 20, driving the footrest 20 to gradually rise, making it easier for the patient to get onto the operating table with the help of the footstool;
[0040] When a patient needs to use a footstool to get off the operating table, the medical staff first step on the lifting foot pedal 402 to raise the foot cover 20 to the required height. Then the patient steps on the foot cover 20 and holds on. Finally, the medical staff releases the lifting foot pedal 402, and the oil circuit on the left side of the cylinder is connected. The oil inlet on the left side of the cylinder is the return oil inlet. The lifting foot pedal 402 acts as a valve to control the hydraulic oil to flow back to the oil tank in the pump. This causes the cylinder to depressurize and the push rod and foot cover 20 to gradually descend, making it easier for the patient to get off the footstool and land on the ground.
[0041] Therefore, the structural design between the base 10, the foot cover 20 and the lifting system 40 is very simple, which facilitates mold making and production, reduces manufacturing costs, and is conducive to market promotion.
[0042] In this embodiment, only a driver 401 needs to be installed in the cavity 101 of the base 10. Then, the lifting control foot pedal 402 arranged at the foot pedal hole 102 is used to control the lifting and lowering of the control foot cover 20. Compared with the complicated method of using a servo motor to control a jack to adjust the height of the footrest in previous medical footrests, the lifting design of the footrest in this application, which uses a lifting foot pedal 402 to control the lifting of the driver 401, is simpler and more convenient, reduces manufacturing costs, facilitates operation by medical staff, and improves the patient's user experience. Moreover, the upper surface of the lifting foot pedal 402 is provided with an anti-slip layer, which can improve the friction when stepping on the lifting foot pedal 402.
[0043] Therefore, compared to the previous method of setting the lifting foot pedal 402 on the outside of the base 10, the present application embodiment, by opening a foot pedal hole 102 on one side of the base 10 and setting the lifting foot pedal 402 corresponding to the foot pedal hole 102, can avoid the lifting foot pedal 402 causing tripping or other obstacles to medical staff and patients when it is set outside the base 10. Moreover, the hidden setting of the lifting foot pedal 402 can improve the overall aesthetics of the footrest and enhance its market competitiveness.
[0044] The footrest cover 20 has a cover plate 201 and a lower extension plate 202. The cover plate 201 is used for the patient to step onto the operating table. The lower extension plate 202 extends vertically downward around the cover plate 201 and is integrally formed with the cover plate 201. If necessary, several lower extension plates 202 can be selected and arranged at intervals around the four sides of the cover plate 201. The upper surface of the cover plate 201 is also provided with an anti-slip layer, which can improve the friction when the patient steps on the cover plate 20 and improve the patient's safety.
[0045] When installing the adjustable, weighable footstool, the foot cover 20 is placed over the upper part of the base 10 and covers the opening of its cavity 101. The lower extension plate 202 of the foot cover 20 can movably cover the upper perimeter of the base 10. Since the driver 401 of the lifting system 40 is installed inside the cavity 101 of the base 10, the drive rod of the driver 401 can be fixedly connected to the cover plate 201. Medical personnel can activate the driver 401 by stepping on the lifting foot pedal 402, causing the drive rod of the driver 401 to simultaneously lift the cover plate 201 vertically on the base 10 to the required height, thereby achieving the purpose of adjusting the footstool to assist patients in getting on and off the operating table.
[0046] The guide assembly 30 has a guide groove 301 and a guide rod 302. The guide groove 301 is vertically mounted on the outer surface of the base 10, and its shape is roughly convex (U-shaped). The opening of the guide groove 301 faces outward from the outer surface of the base 10. The guide rod 302 is mounted on the inner surface of the lower extension plate 202 of the pedal cover 20, and its shape is also roughly convex (U-shaped). Four sets of the guide assembly 30, consisting of the guide groove 301 and the guide rod 302, can be provided. Two sets of these four guide assemblies are respectively provided on the left and right outer surfaces of the base 10 to balance and stabilize the lifting and lowering movements of the left and right sides of the pedal cover 20 on the base 10, thereby improving the lifting and lowering stability of the pedal cover.
[0047] Therefore, when the foot cover 20 is placed over the upper end of the base 10, and the lower extension plate 202 of the foot cover 20 is placed over the upper end of the base 10, the guide rod 302 on the lower extension plate 202 can be fitted into the guide groove 301 of the base 10. This allows the foot cover 20 to be stably raised and lowered on the base 10 through the cooperation of the guide rod 302 and the guide groove 301, and under the drive of the driver 401. Moreover, the covering cooperation between the lower extension plate 202 of the foot cover 20 and the upper end of the base 10 improves the strength of the assembly structure between the foot cover 20 and the base 10, and further improves the stability of the foot cover's raising and lowering.
[0048] The pull rod assembly 50 has a groove plate 501 and a handle 502. Two groove plates 501 are provided, parallel to each other and vertically mounted on one side of the base 10. The groove plates 501 can be installed on either the inner or outer side of the base 10. Furthermore, the cover plate 201 of the foot cover 20 has mounting holes corresponding to the groove plates 501 on the base 10. Therefore, when installing the groove plate 501, the upper end of the groove plate 501 can be inserted through the cover plate 201, exposing its upper surface. Alternatively, the groove plate 501 can be simply installed on the base 10 without needing to insert it through the foot cover 20.
[0049] Additionally, the handle 502 is equipped with two pull rods, the lower ends of which are movably mounted on the slide groove of the slot plate 501. The handle 502 is equipped with a tension button 503, which is connected to a locking head at the lower end of the pull rod. Pressing the tension button 503 retracts the locking head at the lower end of the pull rod, allowing the handle 502 and pull rods to move up and down on the slide groove of the slot plate 501. Releasing the tension button 503 opens the locking head at the lower end of the pull rod and presses against the slide groove of the slot plate 501, thereby locking the assembly position of the pull rod on the slot plate 501 and determining the operating height of the handle 502.
[0050] Therefore, by setting a pull rod assembly 50 on the base 10, medical staff can easily push and drag the footstool by holding the handle 502 of the pull rod assembly 50, which facilitates the movement of the footstool and saves physical strength. The lifting and lowering setting of the handle 502 saves storage space for the footstool. In addition, the pull rod assembly 50 can also be used as a handrail when the patient steps on the footstool, improving the safety of use.
[0051] Based on the above optimized design of the footrest cover 20 and the pull rod assembly 50, it should be noted that after the footrest cover 20 is installed on the base 10, it has a minimum descent height h1 when it is lowered and a maximum rise height h2 when it is raised. h2-h1 is the lifting height H of the footrest cover 20. The range of the lifting height H can be set from 10cm to 15cm. The lifting load of the footrest provided in this embodiment can be up to 90kg, which can be adjusted according to actual usage needs.
[0052] Furthermore, after the handle 502 of the pull rod assembly 50 is assembled with the slot plate 501 via the pull rod, the handle 502 has a minimum lowering height h3 when lowering, and there is no limit to the maximum rising height of the handle 502. Moreover, by setting the maximum rising height h2 of the footrest 20 to be less than the minimum lowering height h3 of the handle 502, the footrest 20 is prevented from being affected by the handle 502 when raising and lowering, thus ensuring the normal raising and lowering operation of the footrest.
[0053] A weighing module 60 is provided on the cover plate 201. This weighing module 60 can optionally use a strain gauge pressure sensor to measure the weight of the patient stepping on the cover plate 20. The weighing module 60 is also connected to a display to show the patient's weight data in real time, reducing repetitive weighing operations for medical staff and improving work efficiency. The weighing module 60 provided in this embodiment, after precise calibration, has a weighing error set within ±0.1 kg, which meets the needs of preoperative weight measurement.
[0054] The bottom of the base 10 is provided with at least two casters 70 and two casters 71. The two casters 70 are installed at two corners at one end of the base 10, and the two casters 71 are installed at two corners at the other end of the base 10.
[0055] Therefore, through the optimized arrangement of two casters 70 and two ferrules 71 on the base 10, the base 10 and the footrest 20 on the base 10 are stably supported and moved, making it easier for medical staff to move the footrest to the required position. Compared with the previous implementation that only set four casters 70 on the base 10, this application replaces two of the casters 70 on the base 10 with ferrules 71, so as to further adjust the height of the footrest according to the patient's usage needs. By adjusting the two ferrules 71, the entire footrest is kept in a horizontal and flat state; and the ferrules 71 lock the footrest in the designated position, preventing the footrest from slipping when the patient uses it. Replacing it with ferrules 71 also improves the footrest's moisture resistance, shock resistance, and flexible movement.
[0056] Second Embodiment
[0057] The difference between this embodiment and the first embodiment is that the guide groove 301 and guide rod 302 of the guide assembly 30 are replaced with sleeve 303 and slide rod 304, and the installation between the guide assembly 30 and the foot cover 20 is also different. The rest are the same, and the same parts will not be described in detail here.
[0058] like Figure 7As shown, when installing the guide assembly 30, the sleeve 303 is vertically installed inside the cavity 101 of the base 10. The lower end of the sleeve 303 is fixedly connected to the bottom of the cavity 101, and the lower end of the slide rod 304 is movably disposed inside the sleeve 303. The upper end of the slide rod 304 is fixedly connected to the cover plate 201 of the foot cover 20. Four sets of guide assemblies 30, consisting of the sleeve 303 and the slide rod 304, can be provided. These four sets of guide assemblies 30 can be installed at the four corners of the cover plate 201 respectively to balance and stabilize the vertical lifting and lowering movement of the entire foot cover 20. This also improves the assembly stability between the foot cover 20 and the base 10.
[0059] Third Embodiment
[0060] The difference between this embodiment and the first embodiment is that a hook 203 is provided on one side of the foot cover 20, and the rest are the same. The same parts will not be described again here.
[0061] like Figure 8 As shown, for unused footrests, this application also provides a hook 203 on one side of the lower extension plate 202 of the footrest cover 20. The footrest can be hooked and connected to the operating table or operating bed through the hook 203. When moving the operating table or operating bed, the footrest can be moved together. Moreover, the height of the hook 203 can be adjusted according to the height of the operating table or operating bed.
[0062] Moreover, when the footstool is hooked to the operating table or operating bed via the hook 203, the footstool's casters 70 and two ferrules 71 can still contact the ground, thus avoiding the footstool from putting too much weight on the operating table or operating bed.
[0063] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
