Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to a medical pendant tower. Background Technology
[0002] Operating towers are essential gas supply medical equipment in modern hospital operating rooms, mainly used for terminal transfer of medical gases such as oxygen, suction, compressed air, and nitrogen in operating rooms. Existing medical pendant systems generally consist of a frame, cantilever, column, and support platform. Small instruments such as CCTV monitors, electrical equipment, anesthesia equipment, and auxiliary medical equipment are placed on the support platform. During use, the cantilever rotates to increase the coverage area of these devices, thereby improving equipment utilization. The existing pendant system's tower head and support platform can be suspended on the circumference of the cantilever's radius by rotation. The large distance between the support points and stress points at the cantilever components places high demands on the strength and deformation resistance of the parts themselves. Under long-term heavy loads, deformation and wear of the rotating mechanism can cause the pendant to automatically "drift" and the support platform to tilt, even causing equipment to fall off the support platform. Furthermore, rotating the support platform by rotating the cantilever requires a significant amount of space in small operating rooms with limited area, creating a cramped environment and inconveniencing medical staff. Additionally, the rotating cantilever structure is relatively complex, requiring rotating joints and various thrust bearings.
[0003] Currently, Chinese patent CN103462697B discloses a medical pendant, including a suspension frame, a cantilever, and a rotating mechanism. The rotating mechanism includes a hanging column connected to the cantilever and a support platform disposed at one end of the hanging column; and a drive mechanism for driving the support platform to rotate. This medical pendant, by incorporating a drive mechanism within the cantilever, allows the support platform to rotate without rotating the cantilever itself, reducing the radiation area of the cantilever. It has a simple structure and occupies little space. By changing the stress point of the cantilever, it avoids cantilever deformation that could cause the support platform to tilt.
[0004] The existing technical solutions have the following drawbacks: the number of devices that can be mounted is limited, and the center of gravity of the hanging column and the supporting platform will shift after the equipment is installed on the hanging column and the supporting platform. Utility Model Content
[0005] The purpose of this invention is to provide a medical pendant system to solve the problems existing in the prior art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A medical pendant tower includes a pendant column, the axis of which is vertically arranged, and multiple load-bearing platforms are spaced apart at the bottom of the pendant column;
[0008] The top of the hanging column is provided with an integrally formed disc part, and the top of the hanging column is fitted with an installation plate. The top of the installation plate fits into the bottom of the disc part, and multiple pressure sensors are evenly arranged axially at the bottom of the disc part.
[0009] A crossbeam is fixedly installed at the bottom of the hanging column, and vertical rods are fixedly installed at the bottom of both ends of the crossbeam. Each load-bearing platform is placed horizontally and is set between two vertical rods. Multiple load-bearing platforms are spaced apart from top to bottom. The load-bearing platforms are fixedly connected to the vertical rods. Multiple through slots are evenly spaced from front to back on the top of each load-bearing platform, and the through slots run through the load-bearing platform from top to bottom.
[0010] By adopting the above technical solution, when multiple devices need to be installed on the column, the data feedback panel is first connected to multiple pressure sensors via electrical signals. The feedback panel reads the readings of each pressure sensor in real time. Then, the multiple devices are placed on the corresponding load-bearing platform, and the position of each device is adjusted so that the readings of the multiple pressure sensors are close to the same. For example, if the weight of the device, column, and load-bearing platform is 500 kg and four pressure sensors are installed, the readings of these four pressure sensors should be 1225 N. However, since it is impossible to adjust them to this value exactly, the allowable error in the design of the device is this value. Assuming the allowable error is ±50 N, then as long as the readings of the four pressure sensors are between 1175 and 1275 N, it is considered qualified. Then, the device is locked to the load-bearing platform by bolts passing through the through slots from bottom to top. After installation, the pressure sensors can be turned off, or the entire column can be monitored through the pressure sensors.
[0011] In a further embodiment, each of the vertical bars is provided with multiple horizontal bars at equal intervals from top to bottom, and the bottom of the load-bearing platform is attached to the top of the horizontal bars.
[0012] By adopting the above technical solution, the horizontal bar can expand the load-bearing area of the vertical bar supporting the load-bearing platform, making the installation of the load-bearing platform more stable.
[0013] In a further embodiment, a fixing plate is fixedly installed on the top of the load-bearing platform.
[0014] By adopting the above technical solution, the fixing plate is fixedly connected to the bottom of the equipment. The area of the fixing plate needs to be set to be larger than the projected area of the bottom of the equipment. Then, the four corners of the top of the fixing plate are provided with waist-shaped holes. The length direction of the waist-shaped holes on the fixing plate is perpendicular to the length direction of the through groove. This setting allows the equipment to be installed at any position on the top of the load-bearing platform.
[0015] In a further embodiment, the top four corners of the fixing plate are provided with waist-shaped holes that run vertically through the plate. The bottom of the load-bearing platform is provided with bolts. The bolts pass through the through grooves from bottom to top and extend into the waist-shaped holes. The bottom end of the bolt is fitted with a first washer, the top end of the bolt is fitted with a second washer, and the top of the bolt is screwed with a lock nut.
[0016] By adopting the above technical solution, the first washer is located at the bottom of the load-bearing platform, and the second washer is located at the top of the fixed plate. The second washer is pressed against the top of the fixed plate by the locking nut. The first and second washers are used to expand the force-bearing area of the bolt and the locking nut, making the locking structure more secure.
[0017] In a further embodiment, an antibacterial mat is laid on top of the load-bearing platform.
[0018] By adopting the above technical solution, since there will still be empty space on the top of the load-bearing platform after the equipment is installed, this empty space can be used to place some consumables, so an antibacterial mat is set up.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. Real-time monitoring of the load-bearing platform's stress status via pressure sensors ensures the stability of the center of gravity of the lifting column and the load-bearing platform, preventing center of gravity shift caused by equipment loading.
[0021] 2. The design of the load-bearing platform allows the equipment to be flexibly installed at different heights on the hanging column, improving the equipment's mounting flexibility and space utilization.
[0022] 3. The horizontal bars enhance the load-bearing capacity of the vertical bars, making the installation of the load-bearing platform more stable and reliable.
[0023] 4. The design of the fixing plate allows the equipment to be precisely installed at any position on the load-bearing platform, improving the installation accuracy and stability of the equipment.
[0024] 5. The locking structure consisting of bolts, washers, and lock nuts ensures the stability of the equipment on the load-bearing platform and prevents the equipment from shaking or falling off during use.
[0025] 6. The antibacterial pad not only provides a clean working environment, but also effectively extends the storage time of consumables. Attached Figure Description
