Description

Technical Field

[0001] This utility model relates to a fixing device, and more specifically, to a fixing device for an injection pump. Background Technology

[0002] Infusion pumps, as medical devices that precisely control drug infusion rates, are widely used in clinical treatment. Their key feature is the ability to provide continuous and stable drug delivery, such as in anesthesia, intensive care, and pain management. However, in practical use, it has been found that moving or transporting patients can easily disrupt the infusion process due to impacts, thus affecting the injection effect. Therefore, an infusion pump fixation device is needed that can absorb impact force and reduce the impact on the pump. Considering the above reasons, how to absorb impact force is the problem addressed in this application. Utility Model Content

[0003] To address the shortcomings of existing technologies, a syringe pump fixing device is provided. This device can absorb impact force when subjected to an impact, reducing the impact on the syringe pump.

[0004] To achieve the above objectives, the following technical solution is provided: an injection pump fixing device, comprising a housing, a buffer assembly, and a fixing assembly. The buffer assembly includes a stabilizing spring, a support plate, a first fixing plate, and a first positioning plate. The stabilizing spring is fixedly connected to the inner wall of the housing. The support plate is fixedly connected to the stabilizing spring. The first fixing plate is fixedly connected to the end of the support plate away from the stabilizing spring. The first positioning plate is fixedly connected to the first fixing plate and forms a gap with the support plate. The fixing assembly includes a main frame, a second fixing plate, and a second positioning plate. The second fixing plate is fixedly connected to the main frame. The second positioning plate is fixedly connected to the second fixing plate and forms a gap with the main frame. Both the second positioning plate and the second fixing plate abut against the first positioning plate.

[0005] In summary, the above technical solution has the following beneficial effects: the combination of the first fixed plate and the first positioning plate, as well as the combination of the second positioning plate and the second fixed plate, can all form a hook-like shape. The hook shape can be detached by mutual abutment. When the shell is impacted, it is first buffered by the stabilizing spring. Normally, the shell is fixed on a certain plane, so the impact only produces an instantaneous impact force. This impact force is buffered by the deformation generated by the stabilizing spring and eventually resets. During the process of deformation and reset, the stabilizing spring will first drive the support plate to move. At this time, the hook formed by the combination of the first fixed plate and the first positioning plate will disengage from the hook formed by the combination of the second positioning plate and the second fixed plate in an instant. After the spring resets, it abuts again. This can prevent the instantaneous impact force from affecting the injection pump installed on the main frame, and achieve the purpose of absorbing the impact force when impacted and reducing the impact on the injection pump.

[0006] The core function of an infusion pump lies in its ability to precisely control the infusion rate of medication. Therefore, impacts can cause minor displacements in the pump's internal mechanical structure or loosening of electronic components, affecting the accuracy of its metering system. Decreased accuracy can lead to infusions that are too fast or too slow, impacting treatment efficacy and potentially causing overdosing or underdosing. Furthermore, modern infusion pumps are often equipped with intelligent control systems capable of pre-programming infusion sequences. Impacts can cause abnormal interruptions or parameter errors, requiring medical staff to reset the sequence, increasing their workload. In emergencies, such as during emergency transport, sequence interruptions can delay treatment. Impacts can also damage the infusion pump's safety mechanisms, such as the emergency stop button or infusion pressure monitoring function, reducing the device's responsiveness in emergency situations. Damaged infusion pumps can also cause drug leaks, posing a potential hazard to patients and medical staff. Frequent collisions accelerate the wear and aging of infusion pump components, shortening the overall lifespan of the equipment. In the long run, this will increase the operating costs of medical institutions. Therefore, this invention can serve as a shockproof and impact-resistant protection device specifically for infusion pumps, reducing the impact of impacts. This invention uses a stabilizing spring as the primary buffer to absorb impact force. By combining a first fixing plate and a first positioning plate, as well as a second positioning plate and a second fixing plate, two hook-type structures are formed. The deformation buffer generated by the stabilizing spring can reduce the actual impact on the infusion pump, thereby achieving the purpose of absorbing impact force and reducing the impact of impacts on the infusion pump.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Reference Figure 1-7 As shown, the injection pump fixing device includes a housing 1, a buffer assembly 2, and a fixing assembly 3. The buffer assembly 2 includes a stabilizing spring 21, a support plate 22, a first fixing plate 23, and a first positioning plate 24. The stabilizing spring 21 is fixedly connected to the inner wall of the housing 1. The support plate 22 is fixedly connected to the stabilizing spring 21. The first fixing plate 23 is fixedly connected to the end of the support plate 22 away from the stabilizing spring 21. The first positioning plate 24 is fixedly connected to the first fixing plate 23 and forms a gap with the support plate 22. The fixing assembly 3 includes a main frame 31, a second fixing plate 32, and a second positioning plate 33. The second fixing plate 32 is fixedly connected to the main frame 31. The second positioning plate 33 is fixedly connected to the second fixing plate 32 and forms a gap with the main frame 31. Both the second positioning plate 33 and the second fixing plate 32 abut against the first positioning plate 24.

[0024] The combination of the first fixed plate 23 and the first positioning plate 24, as well as the combination of the second positioning plate 33 and the second fixed plate 32, can all form a hook-like shape. The hook shape can be moved to form a detachable connection by abutting each other. When the shell 1 is impacted, it is first buffered by the stabilizing spring 21. Under normal circumstances, the shell 1 is fixed on a certain plane, so the impact only generates an instantaneous impact force. This impact force is buffered by the deformation generated by the stabilizing spring 21 and eventually resets. During the process of deformation and reset, the stabilizing spring 21 will first drive the support plate 22 to move. At this time, the hook formed by the combination of the first fixed plate 23 and the first positioning plate 24 will disengage from the hook formed by the combination of the second positioning plate 33 and the second fixed plate 32 in an instant. After the spring resets, it abuts again. This can prevent the instantaneous impact force from affecting the injection pump installed on the main frame 31, and achieve the purpose of absorbing the impact force when impacted and reducing the impact on the injection pump.

[0025] The core function of an infusion pump lies in its ability to precisely control the infusion rate of drugs. Therefore, collisions may cause minor displacements in the pump's internal mechanical structure or loosening of electronic components, thereby affecting the accuracy of its metering system. Decreased accuracy may lead to drug infusion that is too fast or too slow, affecting not only the therapeutic effect but also potentially causing the risk of overdose or underdose. In addition, modern infusion pumps are mostly equipped with intelligent control systems that can preset infusion programs. Collisions may cause abnormal interruptions to the program or incorrect parameters, requiring medical staff to reset, increasing their workload. Even in emergencies, such as during emergency transport, program interruptions may delay treatment. Collisions may also damage the infusion pump's safety mechanisms, such as the emergency stop button or infusion pressure monitoring function, reducing the equipment's responsiveness in emergencies. Damaged infusion pumps may also cause drug leakage, posing a potential hazard to patients and medical staff. Frequent collisions accelerate the wear and aging of infusion pump components, shortening the overall service life of the equipment. In the long run, this will increase the operating costs of medical institutions. Therefore, this utility model can serve as a shockproof and anti-collision protection device specifically for infusion pumps, reducing the impact of shocks.

[0026] This invention uses a stabilizing spring 21 as the primary buffer to absorb impact force. By combining the first fixing plate 23 and the first positioning plate 24, and the second positioning plate 33 and the second fixing plate 32 to form two hook-type structures, the deformation buffer generated by the stabilizing spring 21 can reduce the actual impact on the injection pump, thereby achieving the purpose of absorbing impact force and reducing the impact on the injection pump when it is hit.

[0027] Furthermore, the buffer assembly 2 also includes a first spring 25, a first moving member 251, a first moving rod 252 and a blocking assembly 4. The side of the main frame 31 is provided with a first receiving hole 311 for accommodating the first moving rod 252. The first moving member 251 is fixedly connected to the first moving rod 252. The first spring 25 is fixedly connected in the first receiving hole 311 and fixedly connected to the first moving rod 252. The blocking assembly 4 is located on the side of the first moving member 251 away from the main frame 31.

[0028] The first moving part 251 is attached to the side of the main frame 31, and two sets can be symmetrically arranged. It is supported by the first moving rod 252 and maintained in the horizontal direction. When the first moving part 251 moves, the first moving rod 252 will not detach from the main frame 31. When both first moving parts 251 move away from the main frame 31, it is necessary to apply forces with different directions to the first moving parts 251 at both ends. After the force is stopped, the first moving part 251 will automatically move towards the main frame 31 under the action of the first spring 25. At this time, the two first moving parts 251 will move automatically according to the size of the injection pump, and the symmetrical blocking components 4 will prevent the injection pump from moving, thus fixing the position of the injection pump.

[0029] Furthermore, the buffer assembly 2 also includes a second spring 26, a second moving member 261, a second moving rod 262, and a first blocking member 263. The bottom of the main frame 31 is provided with a second receiving hole 312 for accommodating the second moving rod 262. The second moving member 261 is fixedly connected to the second moving rod 262. The second spring 26 is fixedly connected in the second receiving hole 312 and fixedly connected to the second moving rod 262. The first blocking member 263 is fixedly connected to the second moving member 261.

[0030] The second moving part 261 can be used as a base support, and its movement direction is also limited by the second moving rod 262. When the second moving part 261 moves away from the main frame 31, an outward force needs to be applied to the second moving part 261. After the force is stopped, the second moving part 261 will move automatically toward the main frame 31. The first blocking part 263 provided on the second moving part 261 can prevent the injection pump from falling off. When in use, the injection pump can be placed from top to bottom. At this time, the first moving part 251 and the second moving part 261 will move automatically according to the size of the injection pump. If the injection pump has a special shape, it can also be manually controlled. Under the combined action of the first spring 25 and the second spring 26, the first moving part 251 and the second moving part 261 will move automatically toward the main frame 31. Therefore, without applying additional force, the first moving part 251 and the second moving part 261 can fix the position of the injection pump.

[0031] Furthermore, the main frame 31 is also equipped with a stabilizing telescopic assembly 264 connected to the second moving part 261. Since the second moving part 261 is the main body that carries the injection pump, in order to prevent the second moving rod 262 from being crushed, the stabilizing telescopic assembly 264 is set to disperse the pressure. The stabilizing telescopic assembly 264 can be a telescopic rod or a hydraulic rod, etc.

[0032] Furthermore, the blocking assembly 4 includes a moving block 41, a third spring 42, a third moving member 43, a third moving rod 44, and a second blocking member 45. The third moving member 43 is provided with a third receiving hole 411 for accommodating the third moving rod 44. The moving block 41 is fixedly connected to the third moving rod 44. The third spring 42 is fixedly connected in the third receiving hole 411 and fixedly connected to the third moving rod 44. The second blocking member 45 is fixedly connected to the third moving member 43.

[0033] The first moving part 251 has a groove 253 on the side away from the main frame 31. The groove 253 has multiple receiving slots 254. The moving block 41 has a receiving cavity 412, a through hole 413 communicating with the receiving cavity 412, and a through groove 414 communicating with the receiving cavity 412. The moving block 41 is slidably connected to a sliding part 46 located in the receiving cavity 412. The sliding part 46 is fixedly connected to a control rod 461 that passes through the through hole 413. The control rod 461 is fixedly connected to a pressing part 462 located on the outside of the moving block 41. The pressing part 462 is fixedly connected to a fourth spring 463 fixedly connected to the moving block 41. The sliding part 46 is fixedly connected to a connecting part 464 that extends out of the through groove 414. The connecting part 464 is fixedly connected to a receiving part 465.

[0034] When the pressing member 462 is not pressed, the receiving member 465 is received in the receiving groove 254, and the moving block 41 cannot move.

[0035] When the pressing member 462 is pressed, the receiving member 465 is not contained in the receiving groove 254, and the moving block 41 can move.

[0036] The movable block 41 can move vertically within the groove 253, thereby adjusting the position of the second blocking member 45 to adapt to different injection pumps. The receiving member 465 can fix the position of the movable block 41 by abutting against the inner wall of the receiving groove 254. When the movable block 41 needs to move, the sliding member 46 can be moved by pressing the pressing member 462, thereby causing the receiving member 465 to leave the receiving groove 254. At this time, the movable block 41 can move vertically within the groove 253.

[0037] Furthermore, the third moving part 43 is also fixedly connected to a stabilizing part 47 that is slidably connected to the inner wall of the groove 253. The stabilizing part 47 can be slidably connected to the inner walls of the symmetrical two sides of the groove 253 at the same time, which can improve the stability of the moving block 41 during the movement process. At the same time, it cooperates with the receiving part 465 to fix the position of the moving block 41 and prevent the moving block 41 from rotating.

[0038] Furthermore, the outer casing is also equipped with a viewing window for observing the interior, a handle, a slot for inserting a baffle, and a slot for placing the baffle. The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
