Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a medical pendant rotating arm type power column device. Background Art

[0002] A medical ceiling pendant is a device used to suspend and support medical equipment, usually used in medical places such as operating rooms, ICUs, and emergency rooms.

[0003] In the prior art, such as China Publication No. CN216962905U, the utility model belongs to the field of medical equipment technology, and discloses a medical pendant rotating arm power column device, including a pendant body, a fixed block is fixedly installed on the right side of the pendant body, a fixed rod is fixedly installed inside the fixed block, a limit plate and a flexible spring are movably sleeved on the outer surface of the fixed rod, and a pull block is fixedly installed at the bottom of the limit plate. The utility model sets a limit plate, a flexible spring, a tray and a rectangular frame. Due to the cooperation of the flexible spring and the tray, the tray can drive the rectangular frame to rotate along the inside of the flexible spring, thereby driving the rectangular frame to squeeze the arc surface of the limit plate, so that the limit plate can move to the right along the outer surface of the fixed rod. At the same time, when the tray rotates ninety degrees, the flexible spring is in a compressed state at this time, so it will apply an elastic force to the limit plate, so that the rectangular frame can be limited by the limit plate, and then the tray can be folded.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that when using the medical hanging tower, the tower body reaches the desired position by controlling the rotation of the power column. Sometimes, due to medical needs, the tower body needs to be moved slightly in the horizontal direction. At this time, by controlling the rotation of the power column, the position of the tower body will move too much, which is inconvenient for medical personnel to use. Moreover, when using the tower body, sometimes it is necessary to give the patient an infusion. Some methods control the height of the infusion by installing the infusion stand on the tower body and controlling the lifting and lowering of the rotating arm. This method is not convenient enough. Sometimes the doctor needs to use the tools on the tower body. At this time, the position of the tower body is too high, which affects the use. Utility Model Content

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the present application is not limited to the specific embodiments of the following disclosure.

[0031] Embodiment 1, as Figure 1-5 As shown, the present application provides a medical pendant rotating arm power column device, including a power column 1, and also including:

[0032] The rotating arm 2 is fixedly arranged on one side of the power column 1, and a bottom plate 201 is arranged on one side of the rotating arm 2 by screws, and the bottom plate 201 can be removed by rotating the screws;

[0033] The screw rod 204 is arranged on the inner wall of one side of the bottom plate 201 through a bearing, and a sleeve 205 is threadedly sleeved on the outer surface of the screw rod 204. The screw rod 204 can rotate due to the bearing. When the screw rod 204 rotates and the sleeve 205 does not rotate with it, the sleeve 205 can move on the outer surface of the screw rod 204;

[0034] Two sliders 206 are fixedly arranged on the outer surface of the sleeve 205, and the two sliders 206 are respectively slidably arranged on both sides of the inner wall of the rotating arm 2. The two sliders 206 have a limiting effect on the sleeve 205, so that the sleeve 205 does not rotate with the screw rod 204, and the two sliders 206 can slide on both sides of the inner wall of the rotating arm 2;

[0035] A base 211 is fixedly disposed on one side of the sleeve 205, and a connecting arm 203 is fixedly disposed on one side of the base 211, and the base 211 connects the connecting arm 203 and the sleeve 205 together;

[0036] The bidirectional motor 208 is installed on one side of the rotating arm 2, and the output shaft of the rotating shaft 209 is fixedly provided with the rotating shaft 209. The output shaft of the bidirectional motor 208 can rotate forward and reverse. When the external power supply of the bidirectional motor 208 is turned on, the output shaft drives the rotating shaft 209 to rotate;

[0037] The second gear 210 is fixedly sleeved on the outer surface of the rotating shaft 209, and the outer surface of the second gear 210 is meshedly connected with the first gear 207. When the second gear 210 drives the first gear 207 to rotate, the rotation speed of the second gear 210 will be slower than the rotation speed of the first gear 207, further slowing down the rotation speed of the screw rod 204.

[0038] like Figure 1-5 As shown, the first gear 207 is fixedly sleeved on the outer surface of the screw rod 204, and a protective box 202 is provided on the side of the rotating arm 2 close to the bidirectional motor 208 through screws, and a slide groove is opened on one side of the bottom plate 201. When the bidirectional motor 208 is damaged, the protective box 202 can be removed by turning the screws, and the bidirectional motor 208 can be repaired and replaced. The slide groove allows the connecting arm 203 to move.

[0039] like Figure 1-5 As shown, a tower body 3 is disposed on one side of the connecting arm 203 , and a frame 301 is fixedly disposed on one side of the tower body 3 . The tower body 3 is used to support and suspend medical equipment.

[0040] like Figure 1-5 As shown, vertical poles 302 are fixedly provided on both sides of the inner wall of the frame 301, and a horizontal plate 303 is movably sleeved on the outer surface of the vertical pole 302. The horizontal plate 303 can rotate with the vertical pole 302 as the axis, and the infusion direction can be at different angles by pushing the horizontal plate 303.

[0041] like Figure 4 As shown, a fixing ring 304 is fixedly provided on one side of the horizontal plate 303 , and a threaded rod 305 is threadedly provided on one side of the fixing ring 304 . The fixing ring 304 has a supporting function for the frame 307 .

[0042] like Figure 4As shown, a handle 306 is fixedly provided on one side of the threaded rod 305, and a frame 307 is threadedly provided on the outer surface of the threaded rod 305. By rotating the handle 306, the threaded rod 305 is rotated, and at the same time, it is rotated into the threaded hole on the frame 307 to complete the fixing of the frame 307.

[0043] like Figure 4 As shown, a limit block 308 is fixedly provided on the outer surface of the frame 307, and a hook 309 is fixedly provided on one side of the limit block 308. The limit block 308 has a limiting function on the frame 307. When the frame 307 is not fixed, the frame 307 falls due to gravity. The limit block 308 can prevent the frame 307 from falling off the fixing ring 304, and the hook 309 allows the infusion bag to be hung.

[0044] like Figure 1-5 As shown, the outer surface of the frame 307 is provided with a plurality of threaded holes, and the threaded rods 305 are drawn into the plurality of threaded holes respectively to control different heights of the infusion.

[0045] Working principle: Install the power column 1 at the place of use to complete the installation of the entire medical pendant. When the tower body 3 needs to be moved, the output shaft of the bidirectional motor 208 can rotate forward and reverse by turning on the external power supply of the bidirectional motor 208. By removing the protective box 202, the bidirectional motor 208 can be repaired and replaced when it is damaged, and the output shaft of the bidirectional motor 208 drives the rotating shaft 209 to rotate, and the second gear 210 drives the first gear 207 to rotate, and the screw rod 204 is further rotated. The two sliders 206 can slide on both sides of the inner wall of the rotating arm 2, respectively, and the sleeve 205 is further moved on the outer surface of the screw rod 204, and the connecting arm 203 is moved through the base 211, and the tower body 3 is further moved. The bottom plate 201 is removed from the rotating arm 2 by rotating multiple screws, and the internal parts of the rotating arm 2 can be repaired, so that the tower body 3 can be moved in the water by controlling the rotation direction of the output shaft of the bidirectional motor 208. The horizontal direction can be moved with a small amplitude for convenience of use. There is no need to move the position of the tower body 3 by controlling the rotation of the rotating arm 2. When the patient needs to be infused, the horizontal plate 303 can be rotated with the vertical rod 302 as the axis. By pushing the horizontal plate 303, the infusion direction can be at different angles. When the height of the infusion needs to be adjusted, the threaded rod 305 is rotated by rotating the handle 306 in the opposite direction, so that the threaded rod 305 is removed. At this time, the frame 307 falls under the influence of gravity. When it reaches the bottom, the limit block 308 is on the upper side of the fixing ring 304 to prevent the frame 307 from falling off. At this time, the frame 307 is pulled upward to be at a desired height. The handle 306 is further rotated forward so that the threaded rod 305 is inserted into any threaded hole on the frame 307 to fix the frame 307. At this time, the infusion bag is hung by the hook 309 to perform the infusion work, thereby controlling the angle and height of the infusion of the frame 307 to facilitate the operation of medical personnel and improve convenience.

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
