[0033] Reference Figure 1 This embodiment provides an opening device for use on a rehydration bottle, including a gripping component 1, a connecting component 2, and a fixing component 3;

[0034] The connecting component 2 is fixedly connected to the gripping component 1, and the connecting component 2 is used to connect the bottle cap pull ring of the rehydration bottle;

[0035] The fixing component 3 is disposed on the connecting component 2, and the fixing component 3 is used to clamp the replenishment bottle and restrict the movement of the connecting component 2.

[0036] In the above embodiments, the opening device is specifically designed for opening rehydration bottles. The opening device is preferably made of stainless steel to effectively improve its durability. The opening device includes a gripping component 1, a connecting component 2, and a fixing component 3. The gripping component 1 is the part that the user directly holds. The connecting component 2 is firmly connected to the gripping component 1 and is specifically designed to hook onto the pull ring on the rehydration bottle cap, ensuring a stable operating experience even with frequent use. The fixing component 3 is located on the connecting component 2 and can be clamped at the neck of the rehydration bottle, preferably at the position of the retaining ring. This clamping method effectively limits the movement range of the connecting part 2, preventing the bottle from sliding or tipping over due to excessive pulling during opening. When opening the IV bottle, adjust the angle of the connecting part 2 so that the hook on the connecting part 2 accurately hooks the pull ring on the IV bottle cap. Hold the gripping part 1 and slowly and evenly pull the gripping part 1 upwards, while the fixing part 3 clamps the retaining ring at the neck of the IV bottle to prevent the cap from flying off violently and affecting other colleagues. Use leverage to pull the connecting part 2, thereby opening the IV bottle cap. Therefore, with this opening device, medical staff do not need to directly touch or pull the pull ring with their hands, thus avoiding the risk of finger injury, reducing the time required for each opening, making it easier and faster to handle a large number of IV tasks, improving work efficiency. At the same time, the fixing part 3 limits the excessive movement of the connecting part 2, ensuring stability and accuracy during the opening process.

[0037] Reference Figures 1-2 In one embodiment, the gripping component 1 includes a gripping body 10 and a plurality of protruding ribs 11, the plurality of protruding ribs 11 being obliquely disposed on the gripping body 10, and adjacent protruding ribs 11 being arranged alternately.

[0038] In the above embodiment, the gripping component 1 includes a gripping body 10 and a plurality of ribs 11. The gripping body 10 is the part that the user directly grips and is usually designed in the shape of a handle to adapt to the natural gripping shape of the human hand. In order to increase friction and prevent slippage during operation, a plurality of ribs 11 are provided at the bottom of the gripping body 10. Each rib 11 is a continuous straight line or can be a plurality of protrusions. These ribs 11 are inclinedly arranged on the gripping body 10, and adjacent ribs 11 are staggered to form a V-shaped structure, so that even when the fingers are wet or gloves are worn, a stable grip can be ensured, significantly enhancing the friction during gripping and effectively avoiding operational errors caused by slippage.

[0039] Reference Figures 1-2 In one embodiment, the connecting component 2 includes a connecting rod 20, which is disposed on the side of the gripping body 10 where the protruding rib 11 is provided, and the connecting rod 20 is vertically connected to the middle part of the gripping body 10.

[0040] In the above embodiment, the connecting component 2 mainly includes a connecting rod 20. The connecting rod 20 is located on one side of the grip body 10, which is also the side with multiple anti-slip ribs 11, ensuring the feel and stability during operation. The anti-slip ribs 11 are located close to the connecting rod 20, which means that when the user grips the grip body 10, their fingers can naturally fit against these ribs 11, thereby obtaining the best grip effect. The connecting rod 20 is vertically connected to the middle of the grip body 10, and the connection point is located at the center point of the grip body 10. Due to this connection method between the connecting rod 20 and the grip body 10, the two form a T-shaped structure, which helps to provide better balance and control during use, ensuring that the user can complete the opening operation of the rehydration bottle cap with minimal effort.

[0041] Furthermore, the connecting component 2 also includes a first hook 21. The connecting rod 20 serves as a bridge connecting the gripping body 10 and the first hook 21. One end is fixed to the gripping body 10, and the other end is provided with the first hook 21. The first hook 21 is located at the end of the connecting rod 20 away from the gripping body 10, and the end of the first hook 21 away from the connecting rod 20 is bent toward the gripping body 10 to form a hook-shaped structure. This allows the first hook 21 to effectively hook onto the opening pull ring on the refill bottle cap, making it convenient for the user to apply pulling force by operating the gripping body 10 to open the bottle cap. When the first hook 21 is hooked into the pull ring, the bent design ensures that it will not easily come off even during the upward pulling process, ensuring the stability and reliability of the operation.

[0042] Reference Figure 1 , Figure 3 In one embodiment, the fixing component 3 includes a fixing ring 30 and a clamping assembly 31. The fixing ring 30 is disposed at one end of the connecting rod 20 near the gripping component 1, and the clamping assembly 31 is rotatably connected to the side of the fixing ring 30 away from the connecting rod 20.

[0043] In the above embodiment, the fixing component 3 includes a fixing ring 30 and a clamping assembly 31. The fixing ring 30 is a circular ring structure, which is located at the end of the connecting rod 20 near the gripping component 1 and is fixedly connected to the connecting rod 20. The connecting rod 20 passes through the entire fixing ring 30 and is located at its center. The clamping assembly 31 is rotatably connected to the side of the fixing ring 30 away from the connecting rod 20. This means that the clamping assembly 31 can rotate around an axis to adapt to clamping requirements at different angles. The main function of the clamping assembly 31 is to clamp the bottleneck of the rehydration bottle, preferably at the retaining ring position at the bottleneck. The clamping assembly 31 is located on the side of the fixing ring 30. This layout does not hinder the operation of the connecting rod 20 and can effectively limit the movement of the rehydration bottle during the opening process.

[0044] Furthermore, the fixing ring 30 is provided with a clearance groove 32, which extends a specified distance along the length of the fixing ring 30, allowing the clamping assembly 31 to move freely within a specific range. A rotating shaft 33 is provided in the middle of the clearance groove 32, which is rotatably connected to the side wall of the clearance groove 32 and is set perpendicular to the extension direction of the clearance groove 32. The clamping assembly 31 is connected to the fixing ring 30 through this rotating shaft 33, so that it can swing around the rotating shaft 33 to adapt to clamping requirements at different angles. Since the rotating shaft 33 is located in the middle of the clearance groove 32, it ensures that the clamping assembly 31 can flexibly adjust its angle. The bottom of the clearance groove 32 can be in a state of connection with the outside world, which means that the clamping assembly 31 can swing freely within a certain range without being restricted by the bottom of the clearance groove 32, increasing the flexibility of use.

[0045] Reference Figure 1 , Figure 3 In one embodiment, the clamping assembly 31 includes a first clamping member 310 and a second clamping member 311. The first clamping member 310 and the second clamping member 311 are disposed opposite to each other on both sides of the fixing ring 30, and the lengths of the first clamping member 310 and the second clamping member 311 are respectively greater than the length of the connecting member 2.

[0046] In the above embodiment, the clamping assembly 31 includes a first clamping member 310 and a second clamping member 311. The first clamping member 310 and the second clamping member 311 are disposed opposite to each other on both sides of the fixing ring 30, and their lengths are respectively greater than the length of the connecting member 2. The first clamping member 310 and the second clamping member 311 have the same length, wherein the length is the straight-line distance between the connection point of the clamping rod 3101 and the rotating shaft 33 and the arc-shaped bottom of the second hook 3102. The clamping member and the fixing ring 30 are rotatably connected through the rotating shaft 33, so that the clamping member can be rotated within a certain range. The device can swing freely to adapt to bottlenecks of different shapes and sizes. The first clamping member 310 and the second clamping member 311 form the two sides of an equilateral triangle. The arc-shaped bottom of the first hook 21 in the connecting member 2 is located at the center of this equilateral triangle. In addition, the length of the entire connecting member 2 is about half the length of the first clamping member 310. The length of the connecting member 2 is the straight-line distance between the connection point of the connecting rod 20 and the gripping body 10 and the arc-shaped bottom of the first hook 21, ensuring that the force can be evenly distributed during the pulling process and avoiding operational errors caused by uneven force.

[0047] Reference Figure 1 , Figure 3 In one embodiment, the first clamping member 310 and the second clamping member 311 have the same structure. The first clamping member 310 includes a clamping rod 3101, which is disposed on the rotating shaft 33 and is vertically connected to the middle part of the rotating shaft 33.

[0048] In the above embodiments, the first clamping member 310 and the second clamping member 311 have the same structure. Taking the first clamping member 310 as an example, the first clamping member 310 includes a clamping rod 3101. The clamping rod 3101 is disposed on the rotating shaft 33 and is vertically connected to the middle of the rotating shaft 33. The clamping rod 3101 and the rotating shaft 33 form a T-shaped structure. The connection point between the clamping rod 3101 and the rotating shaft 33 is located in the middle position of the rotating shaft 33. This allows the force to be evenly transmitted to the clamping rod 3101, thereby ensuring the stability and reliability of the clamping assembly 31 during use.

[0049] Furthermore, the first clamping member 310 also includes a second hook 3102. The second hook 3102 is located at the end of the clamping rod 3101 away from the rotation axis 33, and its end is bent toward the connecting member 2. That is, the second hook 3102 is bent inward, so that the second hook 3102 can firmly hook the retaining ring on the neck of the rehydration bottle. This means that the hooks on both the first clamping member 310 and the second clamping member 311 are bent inward, ensuring that the two hooks are arranged opposite each other and their bottoms are on the same plane. When the clamping rod 3101 is adjusted to a suitable angle through the rotation axis 33, wherein the rotation angle of the clamping rod 3101 is less than or equal to 90 degrees, the second hook 3102 can easily hook the retaining ring on the neck of the rehydration bottle and provide additional gripping force through its inward bending design. While ensuring stability, it also provides sufficient flexibility to adapt to neck parts of different shapes and sizes.
