Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a squeezing and shaking structure for large-capacity insulin nutrient solution infusion. Background Technology
[0002] Insulin is a hormone that promotes the uptake of glucose by cells and its conversion into energy. Adding insulin to nutrient solutions primarily helps regulate blood sugar levels to maintain a stable bodily state. When blood glucose levels rise, insulin helps lower high blood sugar, preventing symptoms such as frequent urination, thirst, and fatigue that can result from high blood sugar.
[0003] To ensure a more even distribution of insulin and because some infusion bags and tubing can absorb insulin, shaking the solution periodically can remix the absorbed insulin. Therefore, in clinical practice, 3-liter nutritional solutions containing insulin sometimes require shaking every two hours. However, currently, since the infusion stand does not have a shaking function, medical staff or family members usually have to shake the 3-liter bags manually, which is a great waste of manpower. Utility Model Content
[0004] The purpose of this invention is to provide a squeezing and shaking structure for large-capacity insulin nutrient solution infusion, which aims to solve the problem that in the existing technology, after the three-liter bag is hung on the infusion stand, the infusion stand does not have the function of shaking the three-liter bag, so most of the time it still has to be shaken manually by medical staff or family members, which is a great waste of manpower and energy.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a squeezing and shaking structure for large-capacity insulin nutrient solution infusion, comprising: a hanging part for hanging a three-liter bag, the hanging part being able to rotate to drive the three-liter bag to move up and down; two rotating rollers: disposed below the hanging part, the two rotating rollers being able to approach each other to clamp the three-liter bag, and when the two rotating rollers clamp the three-liter bag, the rotating rollers being able to rotate and move up and down to squeeze the three-liter bag; a mounting part: fixed on the infusion stand, the hanging part being mounted on the mounting part, the mounting part being able to drive the two rotating rollers to move towards or away from each other to clamp the three-liter bag, and being able to drive the hanging part to rotate, causing the three-liter bag to shake up and down; a driving part: mounted on the mounting part, the rotating rollers being mounted on the driving part, and when the two rotating rollers clamp the three-liter bag, the driving part being able to drive the rotating rollers to rotate and move up and down.
[0006] A further technical solution of this utility model is that the hanging part includes two connecting frames, each of which is threaded with a fixing rod, and each of the two fixing rods has a throttle handle fixedly connected to one end that is far apart from the other.
[0007] A further technical solution of this utility model is that the mounting part includes a fixing frame, which can be fixed on the infusion stand. Two sliders are slidably connected inside the fixing frame, and two rotating rollers are respectively installed below the two sliders. Both sliders are threaded with lead screws, and the bottom ends of the two connecting frames are respectively fixedly connected to the ends of the two lead screws that are close to each other. A rotary drive is fixedly connected to one side of the fixing frame, and the output end of the rotary drive extends into the fixing frame and is fixedly connected to one end of the lead screw.
[0008] A further technical solution of this utility model is that the rotary drive component is a servo motor.
[0009] A further technical solution of this utility model is that the driving unit includes two slide rails fixedly connected to the bottom surface of the slider, and a slide plate is slidably connected in both slide rails. The rotating roller is rotatably connected between the two slide plates through a rotating shaft. A gear is provided on the front side of the slide rail, and the gear is fixedly connected to the rotating shaft. When the gear rotates, it can drive the rotating roller to rotate. Two racks are fixedly connected to the bottom surface of the fixed frame, and the racks and gears have a coincident position.
[0010] The beneficial effects of this utility model are:
[0011] The mounting unit is fixed to the infusion stand, and the three-liter bag is hung on the hanging part. The mounting unit pushes two rotating rollers to clamp the three-liter bag, and the drive unit drives the two rotating rollers to rotate and descend along the three-liter bag, thereby squeezing the three-liter bag and mixing the liquid inside. The mounting unit drives the hanging part to rotate, which in turn causes the three-liter bag to shake up and down. At the same time, the mounting unit can push the rotating rollers to move back and forth toward the three-liter bag, which can also shake the three-liter bag. This ensures that the liquid inside the three-liter bag is mixed as thoroughly as possible, avoiding uneven mixing and concentration, and greatly saving manpower.
[0012] In summary, this invention replaces manual, timed shaking care, enabling long-term circadian rhythm maintenance, especially during the deep sleep stage from 11:00 PM to 5:00 AM. Work can be performed as needed, significantly saving manpower and ensuring the continuous stability of the patient. Compared to the 24 / 7 manual, timed operation in traditional care, this invention effectively reduces the disruption to the caregiver's biological clock caused by frequent nighttime awakenings, eliminates care gaps caused by operation intervals, and reduces the risk of movement distortion due to fatigue. It effectively achieves a qualitative leap in nighttime care, transforming it from 'manual on-call' to 'machine-on-call'. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0017] like Figure 1 and Figure 2 As shown, a large-capacity insulin nutrient solution infusion squeezing and shaking structure includes a hanging part for hanging a 3-liter bag. The hanging part can rotate, thereby driving the 3-liter bag to rise and fall, and thus shaking the 3-liter bag to promote the mixing of liquids inside. Two rotating rollers 2 are arranged below the hanging part. The two rotating rollers 2 can approach each other to clamp the 3-liter bag, thereby pushing the liquid inside the 3-liter bag to shake, further promoting the mixing of liquids and minimizing uneven mixing and concentration. The structure also includes an installation... The mounting part is fixed on the infusion stand and is used to drive the two rotating rollers 2 to move towards or away from each other, so as to conveniently drive the rotating rollers 2 to clamp the three-liter bag. The mounting part can also drive the hanging part to rotate, so as to conveniently make the three-liter bag swing up and down. The mounting part is equipped with a drive part, and the rotating rollers 2 are mounted on the drive part. When the two rotating rollers 2 clamp the three-liter bag, the drive part can drive the rotating rollers 2 to rotate and lift, so as to squeeze the three-liter bag and mix the liquid inside the three-liter bag. This eliminates the need for medical staff to manually squeeze and mix the liquid, thus saving manpower.
[0018] like Figure 2 As shown, the hanging part includes two connecting frames 11, each with a fixed rod 12 threadedly connected inside. The ends of the two fixed rods 12 that are far apart from each other are fixedly connected to a handle 13. The hanging hole on the three-liter bag is placed between the two fixed rods 12. By rotating the fixed rods 12 and the handle 13, the fixed rods 12 pass through the hanging hole and the ends of the two fixed rods 12 that are close to each other come into contact with each other, so that the three-liter bag can be easily hung on the fixed rods 12.
[0019] like Figure 1As shown, the mounting section includes a mounting bracket 31, which can be fixed to the infusion stand. Two sliders 32 are slidably connected inside the mounting bracket 31, and two rotating rollers 2 are respectively installed below the two sliders 32. Each slider 32 is threaded with a lead screw 33, and the bottom ends of the two connecting brackets 11 are respectively fixedly connected to the adjacent ends of the two lead screws 33. A rotary drive component 34 is fixedly connected to one side of the mounting bracket 31, and the output end of the rotary drive component 34 extends into the mounting bracket 31 and is fixedly connected to one end of the lead screw 33. The rotary drive component 34 is a servo motor. When the rotary drive 34 is activated, the output end of the rotary drive 34 rotates, which drives the lead screw 33 to rotate. The rotation of the lead screw 33 drives the two sliders 32 to move closer to each other, thereby enabling the two rotating rollers 2 to clamp the three-liter bag. By making the rotating rollers 2 move back and forth, the liquid inside the three-liter bag can be shaken. When the lead screw 33 rotates, it drives the connecting frame 11 to rotate, thereby facilitating the up and down shaking of the three-liter bag. This allows for both clamping and shaking of the three-liter bag, improving the efficiency and effect of liquid fusion.
[0020] like Figure 1 As shown, the drive unit includes two slide rails 41 fixedly connected to the bottom surface of the slider 32. Slide plates 42 are slidably connected within each slide rail 41, and the rotating roller 2 is rotatably connected between the two slide plates 42 via a rotating shaft. A gear 43 is provided on the front of each slide rail 41, and the gear 43 is fixedly connected to the rotating shaft. When the gear 43 rotates, it drives the rotating roller 2 to rotate. Two racks 44 are fixedly connected to the bottom surface of the fixing frame 31, and the racks 44 and gears 43 have overlapping positions. When the two rotating rollers 2 clamp the three-liter bag, the racks 44 mesh with the gears 43. At this time, the gears 43 are connected to an external drive source. While rotating, the gears 43 can move up and down in cooperation with the racks 44. The raising and lowering of the gears 43 drives the rotating rollers 2 to rise and fall, thus allowing the rotating rollers 2 to rise and fall simultaneously while rotating. This facilitates the squeezing of the three-liter bag, allowing the liquid inside to mix without the need for manual squeezing by medical personnel, thereby saving manpower.
[0021] Working principle: First, the mounting part is fixed to the infusion stand. Then, the three-liter bag is hung on the hanging part. Next, the mounting part is activated, causing it to push two rotating rollers 2 to clamp the three-liter bag. Then, the drive part is activated, causing the two rotating rollers 2 to rotate and descend along the three-liter bag, thereby squeezing the three-liter bag and mixing the liquid inside. Then, the mounting part drives the hanging part to rotate, which in turn causes the three-liter bag to shake up and down. At the same time, the mounting part can push the rotating rollers 2 to move back and forth toward the three-liter bag and shake the three-liter bag, thereby making the liquid inside the three-liter bag as fully mixed as possible and avoiding uneven mixing and concentration.
[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
