Description

Technical Field

[0001] The present invention relates to the technical field of cardiovascular medicine treatment, and specifically, to an auxiliary rack for cardiovascular medicine treatment with a tightening function. Background Art

[0002] During the clinical treatment of cardiovascular medicine, patients often need to use a variety of tube-shaped medical devices simultaneously, such as infusion tubes, central venous catheters, arterial pressure monitoring tubes, oxygen tubes, and electrocardiogram monitoring leads. These tube-shaped devices are numerous in quantity, different in specifications, and have a high usage frequency, facing many problems in daily management and use.

[0003] During the treatment of cardiovascular medicine, patients usually need to connect a variety of tube-shaped devices, such as infusion tubes, oxygen tubes, electrocardiogram monitoring wires, drainage tubes, etc. These tube-shaped devices are numerous in quantity and different in specifications, and are extremely easy to tangle with each other during actual use. Tangling will not only affect the operation of medical staff on the devices, such as adjusting the infusion speed, replacing the oxygen tube, etc., resulting in an extended operation time and increasing medical risks; at the same time, the traditional fixing method of the auxiliary rack is single and lacks flexibility, mostly using cumbersome operations such as screws and buckles, which not only increases the workload of medical staff, but also when the patient's body moves or is interfered by external forces, the devices are likely to loosen and shift, posing a safety hazard. And the cumbersome operation requires multiple steps to cooperate whether fixing the devices or removing them, and often requires both hands to operate or the aid of tools, seriously affecting the operation speed. After the devices are taken out, they cannot automatically reset, adding additional preparatory work for the next use and further reducing the overall work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary rack for cardiovascular medicine treatment with a tightening function to solve the problems of effectively separating tube-shaped devices, preventing tangling, and having a flexible adjustment function.

[0005] To achieve the above purpose, an auxiliary rack for cardiovascular medicine treatment with a tightening function is provided, including a support frame. One end of the support frame is fixedly connected with a side plate. The upper and lower ends of the side plate are fixedly connected with fixing plates. A plurality of grooves are formed inside the fixing plates. A mounting block is fixedly connected inside the plurality of grooves. Two clamping blocks are arranged inside the mounting block. A fixing device and a limiting device are arranged inside the mounting block, and the fixing device is arranged below the limiting device; When passing the tube-shaped device through the positions of the two grooves, press the fixing device to move and drive the two clamping blocks to move towards the inside of the mounting block. While the clamping blocks are moving, they approach each other to fix the tube-shaped device. When the fixing device is moving, it is engaged with the limiting device, and the limiting device limits the position of the fixing device. Press the fixing device again to move and disengage from the engagement with the limiting device. The fixing device moves upward to drive the two clamping blocks to open and take out the tube-shaped device.

[0006] As a further improvement of this technical solution, a plurality of elastic bands are fixedly connected to one side where two adjacent fixing plates are located. The plurality of elastic bands are symmetrically arranged in pairs, and the elastic bands separate the tubular equipment.

[0007] The elastic force of the high-tension elastic band applies a separating force to the tubular equipment, causing the equipment to disperse naturally and be arranged in an orderly manner.

[0008] As a further improvement of this technical solution, the fixing device includes a moving block slidably connected inside the mounting block. A connecting block is fixedly connected to the upper end of the moving block. Two clamping blocks are rotatably connected inside the connecting block. A return spring is fixedly connected between the two clamping blocks. The upper end of the connecting block is arc-shaped, and a circular channel is formed between the inner walls of the connecting block and the two clamping blocks.

[0009] The stable fixation of the equipment is achieved through a pressing operation, and the clamping and locking mechanism ensures that the equipment will not loosen or shift due to external pulling during use.

[0010] As a further improvement of this technical solution, a semi-circular arc groove is formed inside the connecting block. A semi-circular block is arranged inside the semi-circular arc groove. One end of the semi-circular block is fixedly connected to a connecting rod. A cylindrical block is fixedly connected to a position near the lower side of the connecting rod away from the semi-circular block. The diameter of the semi-circular arc groove is larger than the diameter of the semi-circular block.

[0011] As a further improvement of this technical solution, a pressing block is fixedly connected to the side of the connecting block away from the connecting rod. A rectangular groove adapted to the pressing block is formed on one side of the mounting block, and the pressing block moves inside the rectangular groove.

[0012] As a further improvement of this technical solution, the limiting device includes a fixed block and a limiting block fixedly connected to the side wall inside the mounting block away from the rectangular groove, and the limiting block is arranged above the fixed block. The cylindrical block is arranged on the inclined surface of the limiting block.

[0013] The fixation and release of the equipment can be completed by pressing with one hand without the aid of tools, and the operation process is simple and efficient.

[0014] As a further improvement of this technical solution, a clamping groove is formed below the limiting block. A limiting groove is formed between the adjacent sides of the fixed block and the limiting block. The width of the limiting groove is larger than the diameter of the cylindrical block, and the cylindrical block slides inside the limiting groove.

[0015] As a further improvement of this technical solution, a compression spring is fixedly connected to the lower side of the semi-circular block away from the connecting rod. The other end of the compression spring is fixedly connected to the inner bottom end of the mounting block, and the compression spring and the semi-circular block are not on the same axis.

[0016] As a further improvement of the technical solution, sliding grooves are provided on both sides of the inner wall of the mounting block, a slider is slidably connected inside the sliding groove, and the slider is fixedly connected to the side wall of the moving block.

[0017] As a further improvement of the technical solution, notches are provided on the two fixing plates, and the notches communicate with the grooves. The adjacent sides of the two elastic bands are flush with the two sides of the notches.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the auxiliary rack for cardiovascular medicine treatment with a tightening function, the return force of the high-tension elastic band exerts a separating force on the tubular equipment, so that the equipment is naturally dispersed and arranged in an orderly manner, without the need for manual adjustment one by one, quickly solving the entanglement problems of infusion tubes, oxygen tubes, etc., significantly improving the equipment sorting efficiency, and enabling medical staff to more conveniently identify and access the equipment.

[0019] 2. In the auxiliary rack for cardiovascular medicine treatment with a tightening function, the equipment is firmly fixed through pressing operation, and the clamping and locking mechanism ensures that the equipment will not loosen and shift due to external pulling force during use.

[0025] Please refer to Figures 1 - 9 As shown, the purpose of this embodiment is to provide an auxiliary rack for cardiovascular medicine treatment with a tightening function, including a support frame 1. One end of the support frame 1 is fixedly connected to a side plate 11. A plurality of universal wheels are arranged below the end of the support frame 1 away from the side plate 11, which is convenient for moving the device. An adjustment component is arranged on the support frame 1 for adjusting the height of the support frame 1. The upper and lower ends of the side plate 11 are fixedly connected to fixed plates 12. A plurality of grooves 14 are opened inside the fixed plates 12. A mounting block 15 is fixedly connected inside the plurality of grooves 14. Two clamping blocks 16 are arranged inside the mounting block 15. A fixing device 2 and a limiting device 3 are arranged inside the mounting block 15, and the fixing device 2 is arranged below the limiting device 3; When passing the tubular equipment through the positions of the two grooves 14, press the fixing device 2 to move, driving the two clamping blocks 16 to move towards the inside of the mounting block 15. While the clamping blocks 16 are moving, they approach each other to fix the tubular equipment. When the fixing device 2 is moving, it is engaged with the limiting device 3, and the limiting device 3 limits the position of the fixing device 2. Press the fixing device 2 again to move and disengage from the limiting device 3, and the fixing device 2 moves upward to drive the two clamping blocks 16 to open and take out the tubular equipment.

[0026] Please refer to Figures 1 - 4 As shown in the figure, on one side where two fixing plates 12 are adjacent, a plurality of elastic bands 13 are fixedly connected. The plurality of elastic bands 13 are symmetrically arranged in pairs. The elastic bands 13 separate the tubular equipment. Notches 17 are formed in the two fixing plates 12, and the notches 17 communicate with the grooves 14. One side where two adjacent elastic bands 13 are located is flush with both sides of the notch 17. When using this device, move the support frame 1 to the side of the hospital bed in the cardiology ward or to the side of the examination table in the examination room, adjust the height of the support frame 1 according to the actual height, then place various types of tubular equipment on the fixing plate 12 in sequence and pass through the grooves 14 in sequence, so that the tubular equipment is located between the two elastic bands 13. Since the elastic bands 13 have tension, various types of equipment can be effectively separated to form an orderly arrangement, avoiding entanglement between the equipment, improving the convenience for medical staff to operate the equipment, and reducing the operation time.

[0027] Please refer to Figures 4 - 9As shown, the fixing device 2 includes a moving block 21 slidably connected inside the mounting block 15. The upper end of the moving block 21 is fixedly connected to a connecting block 28. The inside of the connecting block 28 is rotatably connected to two clamping blocks 16. A return spring is fixedly connected between the two clamping blocks 16. A semi-circular groove 23 is formed inside the connecting block 28. A semi-circular block 24 is arranged inside the semi-circular groove 23. One end of the semi-circular block 24 is fixedly connected to a connecting rod 25. A cylindrical block 26 is fixedly connected to a position near the lower side of the connecting rod 25 away from the semi-circular block 24. The diameter of the semi-circular groove 23 is larger than the diameter of the semi-circular block 24. A pressing block 29 is fixedly connected to the side of the connecting block 28 away from the connecting rod 25. A rectangular groove 27 adapted to the pressing block 29 is formed on one side of the mounting block 15. The pressing block 29 moves inside the rectangular groove 27. When the tubular equipment is placed in the groove 14, the tubular equipment is located on the connecting block 28. The initial state of the two clamping blocks 16 is open. Press the pressing block 29 downward to move it inside the rectangular groove 27. The pressing block 29 drives the connecting block 28 to move downward. The connecting block 28 drives the moving block 21 to move downward. The moving block 21 drives the connecting rod 25 to move downward through the semi-circular block 24. At this time, the compression spring 34 is compressed. When the connecting rod 25 moves downward, it drives the cylindrical block 26 to move downward along the inclined surface of the limiting block 32, causing the semi-circular block 24 to rotate. When the cylindrical block 26 moves to the limiting groove 33 along the inclined surface of the limiting block 32, the clamping groove 35 on the limiting block 32 blocks the cylindrical block 26, enabling the cylindrical block 26 to be clamped at the clamping groove 35, limiting the position of the cylindrical block 26. Since the connecting block 28 drives the two clamping blocks 16 to move downward when moving downward, the outer walls of the two clamping blocks 16 are attached to the inner wall of the mounting block 15, causing the two clamping blocks 16 to move closer to the middle and compress the return spring, fixing the tubular equipment on the connecting block 28, effectively preventing the tubular equipment from loosening or shifting due to pulling during use, ensuring the stable position of the equipment, and facilitating the smooth progress of the treatment.

[0028] Please refer to Figure 8 and Figure 9 As shown, the upper end of the connecting block 28 is arc-shaped. A circular channel is formed between the connecting block 28 and the inner walls of the two clamping blocks 16. Rubber pads are arranged between the side walls of the two clamping blocks 16 and the connecting block 28 to prevent damage to the tubular equipment. A circular channel is formed between the two clamping blocks 16 and the connecting block 28 to fix tubular equipment of different sizes, eliminating the need to replace different fixing devices 2 for equipment of different pipe diameters, improving the versatility and practicality of the device.

[0029] Please refer to Figures 5 - 9As shown in the figure, the limiting device 3 includes a fixed block 31 and a limiting block 32 fixedly connected to the side wall of the inner part of the mounting block 15 away from the rectangular groove 27, and the limiting block 32 is arranged above the fixed block 31. The cylindrical block 26 is arranged on the inclined surface of the limiting block 32. A clamping groove 35 is formed below the limiting block 32. A limiting groove 33 is formed between the adjacent sides of the fixed block 31 and the limiting block 32. The width of the limiting groove 33 is greater than the diameter of the cylindrical block 26. The cylindrical block 26 slides in the limiting groove 33. When it is necessary to remove the tubular equipment, press the pressing block 29 again to drive the moving block 21 to move downward, so that the cylindrical block 26 is disengaged from the clamping connection with the clamping groove 35, and it is extruded and moved in the limiting groove 33. Driven by the reaction force of the compression spring 34, the cylindrical block 26 is reset. The cylindrical block 26 drives the moving block 21 to move upward, thereby driving the two clamping blocks 16 to move out of the inner wall of the mounting block 15, so that the two clamping blocks 16 do not contact the side wall of the mounting block 15. At this time, driven by the reaction force of the return spring, the two clamping blocks 16 are reset, so that the two clamping blocks 16 are in an open state, which is convenient for taking out the tubular equipment and also convenient for fixing the next tubular equipment. The whole process of removing the tubular equipment can be completed only by the simple action of pressing the pressing block 29 again. In the actual cardiology treatment scenario, medical staff often need to quickly adjust or replace equipment. The convenience of single-handed operation enables them to quickly release the fixation of the tubular equipment without the help of additional tools or the assistance of others, greatly saving time.

[0030] Please refer to Figures 6 - 8 As shown in the figure, a compression spring 34 is fixedly connected to the lower side of the semicircular block 24 away from the connecting rod 25, and the other end of the compression spring 34 is fixedly connected to the inner bottom end of the mounting block 15. Since the compression spring 34 and the semicircular block 24 are not on the same axis, there is an offset of the axis between the semicircular block 24 and the compression spring 34. When the cylindrical block 26 moves downward and presses the compression spring 34, when the compression spring 34 applies pressure, the semicircular block 24 will twist to the right, so that the cylindrical block 26 always moves into the limiting groove 33 along the inclined surface of the limiting block 32.

[0031] Please refer to Figure 6 As shown in the figure, sliding grooves are formed on both sides of the inner wall of the mounting block 15, and sliders 22 are slidably connected inside the sliding grooves. The sliders 22 are fixedly connected to the side walls of the moving block 21. Through the cooperation of the sliders 22 and the sliding grooves, the moving block 21 is more stable during the moving process, and the moving effect of the moving block 21 is improved.

[0032] When the auxiliary frame for cardiology treatment with a tightening and loosening function of the present invention is used, medical staff lay various tubular equipment such as infusion tubes and oxygen tubes on the fixing plate 12 in sequence, so that the equipment passes through the groove 14 and is embedded between the two elastic bands 13. The elastic bands 13 are made of high-tension material and use the resilience generated by their own elastic deformation to automatically apply separation force to both sides of the equipment, so that the equipment is naturally dispersed in the horizontal direction to form an orderly arrangement to avoid mutual entanglement, thereby improving the equipment arrangement efficiency; When the tubular device passes through the groove 14, its bottom will be placed on the arc surface of the upper end of the connecting block 28. The medical staff presses the pressing block 29 downward to drive the connecting block 28 to move downward. The connecting block 28 slides in the semicircular groove 23 through the semicircular block 24, thereby pushing the connecting rod 25 to move downward and squeeze the spring 34. As the connecting rod 25 moves downward, the cylindrical block 26 at its end slides along the inclined surface of the limit block 32. During the sliding process, the semicircular block 24 rotates to adapt to the movement trajectory. When the cylindrical block 26 slides into the limit groove 33 and is stuck in the limit block When the clamping groove 35 on the mounting block 15 is engaged, its movement is locked to ensure that the entire linkage structure remains stable. At the same time, the connecting block 28 drives the two clamping blocks 16 to move downward. Since the outer wall of the clamping block 16 fits the inner wall of the mounting block 15, the inner wall exerts an inward squeezing effect on the clamping block 16 during the downward movement, forcing the two clamping blocks 16 to move closer to the middle and squeeze the reset spring, and finally tightly wrapping and fixing the tubular equipment between the clamping blocks 16. The elasticity of the reset spring can also adapt to equipment with different diameters to prevent the equipment from loosening and shifting due to external force. When it is necessary to remove the tubular equipment, the medical staff presses the pressing block 29 again to drive the moving block 21 to move down again, so that the cylindrical block 26 slides in the limit groove 33 to overcome the obstruction of the clamping groove 35 and disengage the clamping state. Under the reaction force of the extrusion spring 34, the cylindrical block 26 is pushed to move back along the limit groove 33 to reset, and the cylindrical block 26 and the moving block 21 move upward, thereby pulling the two clamping blocks 16 out of the inner wall of the mounting block 15, releasing the squeezing constraint of the inner wall on the clamping block 16. At this time, under the reaction force of the reset spring, the two clamping blocks 16 are reset, and the two clamping blocks 16 are quickly opened to restore the initial open state. At this time, the medical staff can easily take out the tubular equipment. The entire operation only requires one-handed pressing, without the help of tools, which greatly shortens the equipment replacement time and meets the needs of fast operation in emergency treatment scenarios in cardiology. After the use is completed, the device automatically resets to prepare for the next fixation of the equipment.
