Description

Technical Field

[0001] This invention relates to the field of storage boxes for nutrient solutions, and more specifically, to a storage box for clinical nutrient solutions. Background Technology

[0002] In current clinical medical technology, nutrient solution storage boxes are important auxiliary equipment for intravenous infusion therapy. They usually need to hold multiple glass or plastic bottles of nutrient solution of the same size at the same time. The common storage box design mainly uses honeycomb-shaped limiting grooves or adjustable partitions in the box to achieve orderly arrangement of the bottles. Although this passive limiting structure can prevent the bottles from colliding with each other, it has functional defects: when the storage box is loaded on a mobile cart for transportation, there are gaps between the bottles and the limiting grooves, which cannot form a fixed position. When the cart passes over uneven ground such as ward thresholds and elevator connections, the bottles will axially shake and radially displace under the action of inertia, resulting in wear on the bottle labels or even liquid leakage.

[0003] More seriously, the lack of active securing devices in existing storage boxes can lead to a series of clinical risks. When the trolley stops or turns suddenly, the unsecured bottles may tip over and collide, not only wasting hundreds of yuan worth of nutrient solutions, but also causing flying glass shards to threaten the safety of medical staff. Some hospitals have tried to compensate for the design deficiencies by adding foam pads or straps, but these temporary measures affect the efficiency of retrieval and are difficult to meet the frequent storage and retrieval needs of dozens of times a day. Especially in scenarios such as the ICU where rapid response is required, medical staff often need to complete the solution preparation operation while on the move. At this time, the unstable state of the bottle will directly affect the accuracy of solution preparation, and may even cause embolism due to air bubbles generated by vibration. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a storage box for clinical nutrition solution to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a storage box for clinical nutritional solutions, comprising a trolley and multiple storage containers mounted on the upper end of the trolley; further comprising a fixing mechanism, the fixing mechanism comprising multiple sliders and a central groove formed on the sliders, an eccentric rod installed in the central groove, an eccentric sleeve rotatably mounted on the eccentric rod, a variable distance plate installed on the eccentric sleeve, the variable distance plate slidably connected in the central groove, a resistance-increasing block installed at the upper end of the variable distance plate, and a top spring and a bottom spring respectively installed at the upper and lower ends of the central groove, the top spring and the bottom spring abutting against the upper and lower ends of the variable distance plate; further comprising a release mechanism, the release mechanism comprising a sealing groove formed at the lower end of the storage containers, a sealing ring installed at the upper end of the sealing groove, and a sealing disc slidably connected in the sealing groove.

[0006] Preferably, the inner wall of the storage bucket is provided with multiple directional grooves at equal intervals, and a slider is slidably connected in each directional groove. A push spring is installed at the bottom of the directional groove, and the other end of the push spring abuts against the slider. This structure ensures that the slider always maintains an outward expansion trend through the elastic restoring effect of the push spring. When the bottle is inserted, it can quickly respond to form an initial clamping force. At the same time, the guiding effect of the directional groove ensures the movement trajectory of the slider, providing a stable mechanical basis for subsequent clamping actions.

[0007] Preferably, a sliding groove is provided between each pair of the deflection grooves, a top spring is installed at the upper end of the sliding groove, and a top ball is installed at the other end of the top spring. The top ball is slidably connected in the sliding groove. The top spring and the top ball form a sliding positioning, which forms support through elastic contact in the initial stage of bottle insertion, automatically correcting the center position of the bottle. At the same time, the rolling contact of the top ball reduces frictional resistance, so that the top spring can smoothly press down to trigger the subsequent clamping mechanism.

[0008] Preferably, each of the storage bins has a flared opening at its upper end, and multiple top springs are respectively locked onto the side wall of the bottle. When the bottle is pressed against the lower end face of the variable distance plate, the resistance block presses against the side wall of the bottle. The flared structure guides the bottle to accurately enter the fixed area, and the variable distance plate converts the downward pressure of the bottle into the radial clamping force of the resistance block, forming an amplified self-locking effect to ensure that the bottle remains stable and fixed under vibration.

[0009] Preferably, a bottom block is installed at the lower end of each of the deflection slots, and the push spring is located at the upper end of the bottom block. A deflection slot is opened on each of the bottom blocks, and a pull rope is installed at the lower end of the slider. The pull rope is slidably connected in the deflection slot. The bottom block serves as a fixed base for the push spring to ensure the efficiency of elastic force transmission. The deflection slot guides the pull rope to form a pull force direction at a specific angle, so that the slider can retract synchronously during the release phase, thereby realizing the rapid release of the clamping force.

[0010] Preferably, the release mechanism further includes multiple rotating strips evenly spaced on the inner wall of the sealing groove, and a rotating groove is provided on the side wall of the sealing disc, the rotating groove engaging with the rotating strips; the rotating strips and the rotating groove form a spiral guide pair, which converts the vertical pressing motion of the bottle into the precise rotation of the sealing disc, while maintaining the stability of the sealing disc during axial movement and avoiding mechanism jamming caused by skew.

[0011] Preferably, a spiral rod is coaxially mounted on the sealing disc, and multiple pull ropes are respectively connected to the side wall of the spiral rod. A thrust bearing is mounted on the upper end face of the spiral rod, and the bottle abuts against the thrust bearing. The spiral rod converts the rotational motion into linear traction of the pull ropes, realizing synchronous control of multiple sliders. The thrust bearing eliminates end face friction when the bottle rotates, ensuring smooth pressing operation and preventing the bottle from rotating accidentally.

[0012] Preferably, the screw rod and the sealing disc are provided with vent holes, one end of which is located on the side wall of the screw rod and the other end of which is located on the lower end face of the sealing disc, and the pull rope is located at the lower end of the vent hole; the vent hole can realize the slow return process of the sealing disc, ensuring that the bottle can be easily pulled out.

[0013] Preferably, the diameter of the sealing ring is larger than the diameter of the helical rod.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a storage box for clinical nutrition solutions, which has the following beneficial effects: This clinical nutrition solution storage box achieves a balance between safe fixation and convenient retrieval through a mechanical linkage design. Its adaptive fixing mechanism utilizes the lever principle of an eccentric rod and a variable distance plate to convert the downward pressure on the bottle into radial clamping force, forming a self-locking effect that tightens as pressure is applied. The top spring guiding system adapts to the bottle to ensure stable fixation, while the bottom push spring maintains the mechanism in a standby state, enabling rapid and continuous operation.

[0015] The storage box features a dual anti-detachment design. The dynamic friction enhancement structure generates additional clamping force when the bottle is subjected to external force, effectively preventing loosening caused by transportation bumps. The quick release system achieves one-button operation through a spiral mechanism; pressing and rotating simultaneously releases all fixing points. Combined with pneumatic buffer control of the reset speed, this linkage design eliminates the need for complex operations during fixing and releasing, improving work efficiency.

[0016] In terms of safety protection, the flared guide structure ensures that the bottle is centered when inserted, reducing the risk of collision during loading and unloading. The all-mechanical structure design is resistant to washing and disinfection. The overall solution takes into account both the convenience and reliability of clinical use, and is particularly suitable for medical scenarios that require frequent movement of nutrient solutions. While ensuring usability, it optimizes the operating experience of medical staff. Attached Figure Description

[0022] Please see Figures 1 to 8A storage box for clinical nutrition solutions includes a trolley 11 and multiple storage containers 12 mounted on the upper end of the trolley 11; it also includes a fixing mechanism, which includes multiple sliders 21 and a central groove 22 formed on the sliders 21. An eccentric rod 23 is installed in the central groove 22, and an eccentric sleeve 24 is rotatably mounted on the eccentric rod 23. A variable distance plate 25 is installed on the eccentric sleeve 24 and is slidably connected in the central groove 22. A resistance block 26 is installed at the upper end of the variable distance plate 25. A top spring 27 and a bottom spring 28 are respectively installed at the upper and lower ends of the central groove 22, and the top spring 27 and the bottom spring 28 abut against the upper and lower ends of the variable distance plate 25. Multiple deflection grooves 29 are equally spaced on the inner wall of the storage containers 12, and a slider 21 is slidably connected in each deflection groove 29. A push spring 21 is installed at the bottom of the deflection groove 29. 0. The other end of the push spring 210 abuts against the slider 21. A slide groove 211 is provided between every two deflection grooves 29. A top spring 212 is installed at the upper end of the slide groove 211. A top ball 213 is installed at the other end of the top spring 212. The top ball 213 is slidably connected in the slide groove 211. A flared opening 214 is provided at the upper end of each storage bucket 12. Multiple top springs 212 are respectively stuck on the side wall of the bottle 215. When the bottle 215 is pressed against the lower end face of the variable pitch plate 25, the resistance block 26 presses on the side wall of the bottle 215. A bottom block 216 is installed at the lower end of each deflection groove 29. The push spring 210 is located at the upper end of the bottom block 216. A turning groove 217 is provided on each bottom block 216. A pull rope 218 is installed at the lower end of the slider 21. The pull rope 218 is slidably connected in the turning groove 217.

[0023] When it is necessary to fix the bottle 215 to the trolley 11, first insert the bottle 215 into the storage bin 12. Since the upper end of the storage bin 12 has a flared opening 214, the bottle 215 can be inserted into the storage bin 12 along the flared opening 214. At first, the bottle 215 will abut against multiple top springs 212. Since the upper end of the top spring 212 is fixedly connected to the slide groove 211, and the other end of the top spring 212 is equipped with a top ball 213, the top ball 213 is slidably connected to the slide groove 211. Therefore, when bottle 215 presses against multiple top springs 212, the top springs 212 are compressed. Then, the lower top ball 213 slides along the groove 211 to adapt to the diameter of bottle 215. At this point, it continues to move downward until bottle 215 passes through the position of multiple drag-increasing blocks 26. Then, it continues to slide downward until bottle 215 abuts against the side wall of multiple pitch plates 25. At this point, bottle 215 presses against pitch plates 25, and as it continues to move downward, it causes the lower end of pitch plates 25 to contract. Furthermore, the bottom spring 28 is compressed. Due to the contraction of the variable pitch plate 25 along the eccentric rod 23, the other end of the variable pitch plate 25 extends outward and approaches the bottle 215. As it continues to move downward, it continuously presses against the variable pitch plate 25, thus continuously applying pressure. The distance from the lower end of the variable pitch plate 25 to the eccentric rod 23 is much greater than the distance from the friction block 26 to the eccentric rod 23, thus greatly increasing the torque. As the bottle 215 continues to move downward and passes through the variable pitch plate 25, the variable pitch plate 25 is pushed to its maximum distance. Therefore, the friction block 26 applies maximum pressure against the side wall of the bottle 215, ensuring stable fixation. This causes the bottle 215 to be stuck inside the storage container 12, thus completing the fixation of the bottle 215. When the bottle 215 is pulled upward again, the slider 21 contracts along the deflection groove 29, applying lateral pressure, which also ensures the stability of the bottle 215 fixation and improves the safety of use.

[0024] Because the thrust of the bottom spring 28 is greater than that of the top spring 27, the lower end of the pitch plate 25 will be extended outward when in normal state, while the resistance block 26 will retract inward, ensuring that the bottle 215 can be easily inserted.

[0025] To put it simply, the fixing process involves inserting the bottle 215 into the storage container 12 and pressing it down continuously. The variable distance plate 25 and the eccentric rod 23 apply pressure to the friction block 26, causing the friction block 26 to lock onto the side wall of the bottle 215, thus ensuring the fixing process. As the bottle 215 moves upward, it causes the slider 21 to contract upward along the direction change groove 29, which increases the friction force, thus ensuring the self-locking fixing process.

[0026] The opening mechanism includes a sealing groove 31 at the lower end of the storage container 12, a sealing ring 32 installed at the upper end of the sealing groove 31, and a sealing disc 33 slidably connected inside the sealing groove 31. The opening mechanism also includes multiple rotating strips 34 evenly spaced on the inner wall of the sealing groove 31, a rotating groove 35 on the side wall of the sealing disc 33, the rotating groove 35 engaging with the rotating strips 34, a spiral rod 36 coaxially mounted on the sealing disc 33, multiple pull ropes 218 connected to the side wall of the spiral rod 36, a thrust bearing 37 installed on the upper end face of the spiral rod 36, the bottle 215 abutting against the thrust bearing 37, vent holes 38 on the spiral rod 36 and the sealing disc 33, one end of the vent hole 38 being on the side wall of the spiral rod 36, the other end of the vent hole 38 being on the lower end face of the sealing disc 33, the pull rope 218 being at the lower end of the vent hole 38, and the diameter of the sealing ring 32 being larger than the diameter of the spiral rod 36.

[0027] When it is necessary to loosen the connection between bottle 215 and storage container 12, since bottle 215 and storage container 12 are currently fixed, continuously pressing down on bottle 215 causes it to press against thrust bearing 37, which in turn applies a thrust to screw rod 36. Screw rod 36 moves downwards, and rotating groove 35 engages with rotating bar 34, causing screw rod 36 to rotate while moving downwards. Multiple pull ropes 218 are connected to the side wall of screw rod 36, causing the pull ropes 218 to not only rotate but also move downwards. Therefore, the downward movement alone increases the contraction of pull ropes 218. Since pull ropes 218 are connected to slider 21, and the contraction of pull ropes 218 involves both downward movement and rotation... Therefore, the downward speed of slider 21 is greater than the speed of bottle 215, which causes the friction-increasing block 26 to release the fixed friction between itself and bottle 215. The sealing disc 33 and the sealing groove 31 are in a sealed connection, so the air between the sealing groove 31 and the sealing disc 33 will be discharged through the vent 38. Thus, the process of releasing the friction-increasing block 26 and bottle 215 is completed. At this time, quickly pulling the bottle 215 upward will release the connection between it and the storage bucket 12. Because slider 21 will move upward under the action of push spring 210, but the diameter of vent 38 is very small, the speed at which air is sucked into the sealing groove 31 is very slow, thus providing time for bottle 215 to be pulled out. It will also slowly return, thus completing the use process.

For all the fixed connections mentioned above, welding is preferred.
