Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a multifunctional infusion stand for oncology departments. Background Art

[0002] The oncology department is a department in the hospital that specializes in the diagnosis, treatment, and research of tumor diseases. It mainly provides comprehensive treatment services for various patients with benign and malignant tumors. The diagnosis and treatment scope of the oncology department covers a variety of tumor types, including but not limited to lung cancer, breast cancer, gastrointestinal tumors, gynecological tumors, urinary system tumors, lymphoma, head and neck tumors, etc. In the daily treatment of the oncology department, infusion is one of the common and important treatment methods. Especially for patients who need long-term chemotherapy, nutritional support, or drug infusion, the infusion stand, as an auxiliary device during the infusion process, provides a stable hanging point for the infusion bottle or infusion bag to ensure the smooth progress of the infusion process;

[0003] In the clinical practice of the oncology department, patients often need to infuse multiple drugs simultaneously, and multiple infusion bottles need to be hung on the infusion stand. When multiple infusion bottles are hung on one side of the infusion stand at the same time, due to the relatively high center of gravity of the infusion stand, it is prone to tipping when carrying multiple infusion bottles, resulting in the infusion bottles falling and being damaged. In addition, the ward is crowded with people, and patients, family members, and medical staff move around frequently, further increasing the probability of the infusion stand being collided and exacerbating the risk of the infusion stand tipping. This instability not only affects the safety and continuity of the infusion, but also may have potential negative impacts on the treatment effect of patients and ward management.

[0004] To solve the above problems, a multifunctional infusion stand for oncology departments is proposed in this application. Summary of the Invention

A thread is provided on the inner side of the bottom of the first threaded shaft. A first threaded shaft threadedly connected to the thread is provided at the bottom of the suspension cylinder, and a plurality of counterweight blocks are stacked in the suspension cylinder.

[0020] The above technical solution of the present invention has the following beneficial technical effects:

[0021] 1. When the present invention is in use, the central adsorption component is separated from the bottom of the infusion stand body, adsorbed on the ground, and then the traction ropes around the hollow column are pulled to lift the central adsorption component through the pull rope assembly, maintaining a certain pulling force, and then the traction rope is tilted to make the traction adsorption component connected with the traction rope adsorbed on the ground. Since the traction ropes are arranged around the infusion stand body, the hollow column can be pulled. Even if the medicine bottles hung on the infusion stand body are all on one side, the traction of the traction rope can keep the hollow column stable, and when a pedestrian collides with the hollow column, the traction of the traction rope can be used to pull the traction adsorption component. The elastic traction member on the component is pulled, and buffered under the action of the elastic traction member. When the traction rope is pulled, the force can be transmitted to the central adsorption component through the pull rope component, so as to keep the infusion stand body always in the original position and not move. Through the synergistic effect of the central adsorption component, the traction rope and the traction adsorption component, the present invention can effectively maintain the stability of the hollow column even if the medicine bottles hung on the infusion stand body are concentrated on one side. This structural design can resist the external force caused by the uneven distribution of medicine bottles and the collision of pedestrians, avoid the infusion stand body from tipping over, ensure the safety and continuity of the infusion process, and reduce the risk of infusion bottles falling and being damaged due to the tipping over of the infusion stand body.

[0022] 2. When a pedestrian hits the hollow column, the force is transmitted to the traction rope, causing the elastic traction member on the traction adsorption assembly to be pulled, and the elastic traction member is deformed immediately. When the elastic traction member is deformed, it can drive the ringing member to vibrate. When the ringing member vibrates, it can make a sound to serve as a reminder. This reminder function can attract the attention of pedestrians in time, making them aware of the collision with the main body of the infusion stand, so that measures can be taken to avoid another collision or further interference, reduce the probability of instability of the main body of the infusion stand or interruption of infusion due to collision, and ensure the safety of the infusion environment in the ward;

[0023] 3. When a pedestrian hits the hollow column, the corresponding traction rope will be pulled. Since the traction rope bypasses the elastic roller on the elastic guide assembly, the traction rope will drive the elastic roller to deform. Under the elastic action of the elastic roller, the traction rope can return to its original position. This buffer mechanism can effectively absorb the impact force generated by pedestrians hitting the main body of the infusion stand, reduce the impact of the impact on the stability of the main body of the infusion stand, and further enhance the stability of the main body of the infusion stand in a complex environment, so that it can better adapt to the situation of frequent movement of people in the ward;

[0024] 4. When a pedestrian hits the hollow column, causing the traction rope to pull the elastic traction member, the magnetic rod then moves upward, passes through the insertion hole opened at the bottom of the loading cylinder, and abuts against the bladder cylinder inside. Since there is magnetorheological fluid in the bladder cylinder, when the magnetic rod gradually applies pressure to the bladder cylinder, the magnetorheological fluid hardens, limits the position of the upward movement of the magnetic rod, and the bladder cylinder exerts a reaction force on the magnetic rod, enabling the magnetic rod to quickly rebound. This process not only further enhances the stability of the infusion rack body when it is hit, but also enables the infusion rack body to quickly return to the balanced state, reduces the shaking time of the hollow column caused by the collision, ensures the smooth progress of the infusion process, and improves the efficiency of ward infusion management;

[0025] 5. During the use of the present invention, the infusion bottle can be hung on the hook of the suspension cylinder. Since there are two suspension cylinders symmetrically arranged on the loading plate, when there are too many infusion bottles hung on the hook of one suspension cylinder, the first threaded shaft at the bottom of the suspension cylinder for hanging the infusion bottle can be screwed out, and a part of the counterweight block in the suspension cylinder can be taken out, so that the weights of the two suspension cylinders are about the same, preventing one side from being too heavy and the other side from being too light, and playing a balancing role. This adjustable balance design can adapt to different infusion situations, avoid the center of gravity of the infusion rack shifting due to uneven distribution of medicine bottles, further improve the stability and reliability of the infusion rack body, and provide a safer and more stable infusion environment for patients.

Detailed implementation manners

[0038] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0039] As Figures 1-11 shown, a multifunctional infusion stand for oncology proposed by the present invention includes an infusion stand main body 1, a central adsorption assembly 2, a drawstring assembly 3 and an elastic feeding assembly 4;

[0040] The infusion stand main body 1 includes a hollow column 11. The central adsorption assembly 2 is detachably connected to the bottom of the infusion stand main body 1. The drawstring assembly 3 is arranged in the hollow column 11 and is connected to the central adsorption assembly 2. The elastic feeding assembly 4 is fixed in the middle of the hollow column 11. The elastic feeding assembly 4 includes a plurality of elastic roller members 41, and the plurality of elastic roller members 41 are respectively installed around the elastic feeding assembly 4;

[0041] The drawstring assembly 3 includes multiple traction ropes 33. The multiple traction ropes 33 respectively pass through the four sides of the hollow column 11 and bypass multiple elastic roller members 41 and incline downward. One end of each of the multiple traction ropes 33 is connected with a traction adsorption assembly 5 adsorbed on the ground;

[0042] The traction adsorption assembly 5 includes an elastic traction member 52 and a ringing member 53. The elastic traction member 52 is connected with one end of the traction rope 33, and the ringing member 53 is installed at the bottom of the elastic traction member 52.

[0043] During use, the central adsorption assembly 2 is separated from the infusion stand main body 1, and then the central adsorption assembly 2 is adsorbed on the ground. By pulling the traction rope 33, the central adsorption assembly 2 is lifted through the drawstring assembly 3 and the pulling force is maintained. Then the traction rope 33 is inclined to make the traction adsorption assembly 5 adsorb the ground. When an external force acts on the infusion stand main body 1, the traction rope 33 can play a role in traction and stability for the hollow column 11. If a collision occurs, the traction rope 33 pulls the elastic traction member 52, and the elastic traction member 52 buffers, and at the same time drives the ringing member 53 to make a sound for reminder. The traction rope 33 bypasses the elastic roller member 41, and the elastic roller member 41 can buffer and absorb the impact force during the collision, reducing the influence on the stability of the infusion stand main body 1.

[0044] As Figure 1 and Figure 4 shown, in this embodiment, the traction adsorption assembly 5 includes fixing cylinders 51. A plurality of fixing cylinders 51 are respectively arranged around the hollow column 11. A second suction cup 54 adsorbed on the ground is installed at the bottom of the fixing cylinder 51. The elastic traction member 52 is installed in the fixing cylinder 51, and the end of the elastic traction member 52 extends out of the top of the fixing cylinder 51. The ringing member 53 is placed in the fixing cylinder 51.

[0045] The fixing cylinder 51 is adsorbed on the ground through the second suction cup 54, providing an installation position for the elastic traction member 52 and the ringing member 53. When the traction rope 33 is stressed, it pulls the elastic traction member 52 to move in the fixing cylinder 51, thereby driving the ringing member 53 to vibrate and make a sound. At the same time, the fixing cylinder 51 can limit the movement direction of the elastic traction member 52 to ensure its stable operation.

[0046] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, in this embodiment, the elastic traction member 52 includes a second piston 521, a magnetic rod 522, and a second spring 523. The second piston 521 is slidably disposed within the fixed cylinder 51. The ringer 53 is mounted at the bottom of the second piston 521. The magnetic rod 522 slidably passes through the top of the fixed cylinder 51 and is connected to the second piston 521. The second spring 523 is sleeved on the magnetic rod 522 and is located within the fixed cylinder 51, and both ends of the second spring 523 are respectively connected to the second piston 521 and the top inside the fixed cylinder 51. A traction plate 524 is fixedly sleeved on the magnetic rod 522 and is located above the fixed cylinder 51. One end of the traction rope 33 is connected to the traction plate 524. An air hole 511 is formed at the top of the fixed cylinder 51. The side of the fixed cylinder 51 is mounted with a loading cylinder 55 above it through a mounting bracket 512. A bladder cylinder 551 is disposed within the loading cylinder 55. A magnetorheological fluid is disposed within the bladder cylinder 551. A jack 552 corresponding to the magnetic rod 522 is formed at the bottom of the loading cylinder 55.

[0047] When the traction rope 33 pulls the traction plate 524, it drives the magnetic rod 522 to move upward. The second spring 523 is stretched to play a buffering role. At the same time, the magnetic rod 522 drives the second piston 521 to move, thereby driving the ringer 53 to emit a sound. When the magnetic rod 522 moves upward through the jack 552 and abuts against the bladder cylinder 551, the magnetorheological fluid within the bladder cylinder 551 hardens, restricting the movement position of the magnetic rod 522 and applying a reaction force to cause it to rebound, enhancing the stability of the infusion stand main body 1 when it is impacted.

[0048] As Figure 5 shown in the figure, in this embodiment, the ringer 53 includes a third spring 531 and a bell 532. The third spring 531 is mounted at the bottom of the second piston 521. The bell 532 is connected to the bottom of the third spring 531.

[0049] When the second piston 521 moves due to the action of the elastic traction member 52, it drives the third spring 531 to expand and contract. The bell 532 vibrates under the action of the third spring 531, thereby emitting a sound and realizing the reminder function.

[0050] As Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown in the figure, in this embodiment, the central adsorption assembly 2 includes a central cylinder 21. A shaft cylinder base 113 is installed at the bottom end of the hollow column 11. Moving supports 114 are installed around the shaft cylinder base 113. Rollers 115 are installed at the bottom of the moving supports 114. The central cylinder 21 is arranged below the shaft cylinder base 113. A threaded channel communicating with the hollow column 11 is opened in the shaft cylinder base 113. A second threaded shaft 23 threadedly connected to the threaded channel is installed at the top of the central cylinder 21. A first suction cup 22 is installed at the bottom of the central cylinder 21, and the first suction cup 22 is used to adsorb on the ground. An elastic pulling member 24 is installed in the central cylinder 21. The bottom end of the pulling rope assembly 3 is connected to the elastic pulling member 24.

[0051] By rotating the second threaded shaft 23 to screw it out of the threaded channel opened in the shaft cylinder base 113, then adsorbing the first suction cup 22 at the bottom of the central cylinder 21 on the ground to provide a stable support point for the infusion rack main body 1. When the pulling rope assembly 3 is stressed, it pulls the elastic pulling member 24, and the elastic pulling member 24 can buffer the pulling force to ensure the stability of the infusion rack main body 1.

[0052] As Figure 7 shown in Figure 8 the figure, in this embodiment, the elastic pulling member 24 includes a first piston 241, a pull rod 242 and a first spring 243. The first piston 241 is slidably arranged in the central cylinder 21. The pull rod 242 slidably passes through the second threaded shaft 23 and the top of the central cylinder 21 and is connected to the first piston 241. The first spring 243 is sleeved on the pull rod 242 and is located in the central cylinder 21, and both ends of the first spring 243 are respectively connected to the first piston 241 and the top inside the central cylinder 21. The bottom end of the pulling rope assembly 3 is connected to the pull rod 242.

[0053] When the pulling rope assembly 3 pulls the pull rod 242, the first piston 241 moves in the central cylinder 21, and the first spring 243 is stretched or compressed. The elasticity of the spring is used to buffer the pulling force transmitted by the pulling rope assembly 3, further enhancing the stability of the infusion rack main body 1.

[0054] As Figure 3 shown in Figure 9 and Figure 10 the figure, in this embodiment, the pulling rope assembly 3 further includes a pulling rope body 31 and a shaft block 32. The pulling rope body 31 is vertically arranged in the hollow column 11. A shaft block 32 slidably matched with the hollow column 11 is installed at the top end of the pulling rope body 31. The bottom end of the pulling rope body 31 is connected to the pull rod 242. Openings 116 are respectively opened around the hollow column 11. A plurality of pulling ropes 33 respectively pass through the plurality of openings 116, and the other ends of the plurality of pulling ropes 33 are all connected to the top of the shaft block 32.

[0055] When the towing rope 33 is pulled, the towing rope 33 drives the shaft block 32 to slide within the hollow column 11, thereby pulling the rope body 31. The rope body 31 then pulls the pull rod 242, achieving the lifting of the central adsorption assembly 2, and at the same time transmitting the pulling force of each towing rope 33 to the central adsorption assembly 2 to ensure the stability of the infusion stand main body 1.

[0056] As Figure 1 shown in Figure 9 In this embodiment, the elastic conveying assembly 4 further includes a conveying disk 42. The conveying disk 42 is fixedly sleeved on the middle part of the hollow column 11 and is located below the opening 116. Notches are formed around the conveying disk 42, and the elastic roller members 41 are installed in the notches.

[0057] The elastic roller member 41 includes a conveying plate 411. The tops of a plurality of conveying plates 411 are respectively rotatably connected to a plurality of notches. An open end is formed at the bottom of the conveying plate 411, and a horizontally arranged first conveying roller 412 is rotatably connected within the open end. Arc-shaped elastic rods 413 are connected between a plurality of conveying plates 411 and the hollow column 11. Second conveying rollers 414 are horizontally rotatably connected within a plurality of notches. The towing ropes 33 pass through the notches and the open ends and respectively bypass the bottoms of the second conveying rollers 414 and the tops of the first conveying rollers 412.

[0058] When the towing rope 33 is stressed, it drives the elastic roller member 41 to act. The conveying plate 411 rotates around the connection point, and the arc-shaped elastic rod 413 undergoes elastic deformation. The first conveying roller 412 and the second conveying roller 414 rotate. Through the coordinated action of these components, the impact force received by the towing rope 33 is buffered, and after being stressed, the towing rope 33 returns to its original position, enhancing the stability of the infusion stand main body 1.

[0059] As Figure 1 shown in

[0060] In this embodiment, a plug rod 111 is inserted into the infusion stand main body 1. A bolt 112 that presses against the plug rod 111 is threadedly connected to the top end of the infusion stand main body 1. A loading disk 12 is installed at the top of the plug rod 111, and two counterweight suspension assemblies 13 are symmetrically installed on the loading disk 12.

[0061] The position of the plug rod 111 can be fixed by the bolt 112, thereby stabilizing the loading disk 12. The counterweight suspension assembly 13 is used to suspend the infusion bottle. The two symmetrically arranged counterweight suspension assemblies 13 can balance the center of gravity of the infusion stand main body 1 by adjusting the number of infusion bottles suspended thereon or taking out the counterweight blocks 134 from the suspension cylinders 131 to prevent the center of gravity from shifting due to uneven distribution of the medicine bottles. Figure 1 As Figure 11As shown in the figure, in this embodiment, the counterweight suspension assembly 13 includes a suspension cylinder 131. Two mounting holes are symmetrically formed on the loading tray 12. The tops of the two suspension cylinders 131 are respectively fixed in the two mounting holes. A plurality of hooks 132 arranged at intervals are installed on one side of each of the two suspension cylinders 131 away from each other. The inner side of the bottom of the first threaded shaft 133 is provided with threads. The bottom of the suspension cylinder 131 is provided with a first threaded shaft 133 threadedly connected to the threads. A plurality of counterweight blocks 134 are stacked in the suspension cylinder 131.

[0062] The infusion bottle is hung on the hook 132. When there are too many infusion bottles hung on one side of the suspension cylinder 131, the first threaded shaft 133 is screwed out, and some counterweight blocks 134 are taken out from the suspension cylinder 131 to adjust the weights of the two suspension cylinders 131, so that the infusion rack main body 1 is balanced and the safety and stability of the infusion process are ensured.

[0063] The specific working principle of the present invention is as follows:

[0064] During use, the second threaded shaft 23 is screwed out of the threaded channel formed in the shaft cylinder base 113 by rotation. Subsequently, the first suction cup 22 at the bottom of the central cylinder 21 is adsorbed on the ground. The traction rope 33 around the hollow column 11 is pulled. The traction rope 33 drives the shaft block 32 to slide in the hollow column 11, and then pulls the rope body 31. The rope body 31 pulls the pull rod 242, so that the first piston 241 moves in the central cylinder 21. The first spring 243 buffers the pulling force, lifts the central adsorption assembly 2 and maintains a certain pulling force. After that, the traction rope 33 is inclined, so that the second suction cup 54 of the traction adsorption assembly 5 is adsorbed on the ground;

[0065] When the medicine bottles hung on the infusion rack main body 1 are concentrated on one side or the infusion rack is collided by pedestrians, the traction rope 33 plays a role in stabilizing the traction of the hollow column 11. If a collision occurs, the traction rope 33 pulls the traction plate 524 of the elastic traction member 52, drives the magnetic rod 522 to move upward. The second spring 523 buffers. At the same time, the magnetic rod 522 drives the second piston 521 to move, so that the bell 532 of the ringing member 53 vibrates and sounds a reminder under the action of the third spring 531. The magnetic rod 522 moves upward through the insertion hole 552 at the bottom of the loading cylinder 55 and abuts against the bladder cylinder 551. The magnetorheological fluid in the bladder cylinder 551 hardens, restricts the movement of the magnetic rod 522 and makes it rebound, enhancing the stability of the infusion rack main body 1;

[0066] The traction rope 33 bypasses the elastic roller member 41 of the elastic feeding assembly 4. During a collision, the traction rope 33 drives the feeding plate 411 to rotate. The arc-shaped elastic rod 413 deforms, and the first feeding roller 412 and the second feeding roller 414 rotate, buffering and absorbing the impact force and making the traction rope 33 return to its original position;

[0067] When infusing, hang the infusion bottle on the hook 132 of the counterweight suspension assembly 13. If there are too many infusion bottles hanging on one side of the suspension cylinder 131, unscrew the first threaded shaft 133 and take out some counterweight blocks 134 from the suspension cylinder 131 to balance the weights of the two sides of the suspension cylinder 131, ensuring the stability of the main body 1 of the infusion stand and guaranteeing the safety and continuity of the infusion process.
