Description

Technical Field

[0001] The present application relates to the technical field of medicine bottle opening, and in particular to a bottle opening device. Background Art

[0002] To open existing medicine bottles, the plastic pull tab on the bottle cap must be pulled down to expose the rubber portion. Medical personnel then draw up the medication with a syringe, pierce the rubber portion, and inject it into the infusion bottle. Medical personnel typically remove the pull tab manually, but the large amount of medication added to infusion bottles daily often causes pain or swelling in the fingers of medical personnel.

[0003] To this end, Chinese utility model patent application number 2019202638091 discloses a medical infusion bottle pull ring remover that installs a pull ring hook on the handle to pull out the pull ring instead of fingers.

[0004] However, the above pull ring remover has the following problems when used: 1. When applying force by holding the handle, the force is not applied completely to the pull ring, which does not achieve the effect of labor saving. 2. When operating, the hook needs to be aligned and hooked into the pull ring, which is also time-consuming. Summary of the Invention

[0005] The utility model provides a bottle opening ring device, which can clamp the pull ring through the clamping claws and then pull it up, thus saving labor and not requiring the pull hook for positioning, thereby improving the efficiency of pulling out the pull ring.

[0015] Preferably, a pull plate is provided at the upper end of the force applying rod.

[0016] Preferably, a wristband is provided on the outside of the accommodating tube.

[0017] Preferably, the lower end of the accommodating cylinder is provided with a fixing ring adapted to the mouth of the reagent bottle.

[0027] The following will describe the implementation methods of this application in detail with reference to the accompanying drawings and examples, so that the application can fully understand how technical means are used to solve technical problems and achieve corresponding technical effects, and implement them accordingly. The embodiments of this application and the various features therein can be combined with each other without conflict, and the resulting technical solutions are all within the scope of protection of this application.

[0028] It should be clear that the embodiments described below are only some of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application. Example

[0029] This embodiment describes in detail the scheme of simulating a spawning site:

[0030] like Figure 1-Figure 4 The bottle opening ring device shown in the figure comprises a hollow receiving tube 12, an elastic spring 4, an applying rod 3, a piston plate 5, and a claw 9. The applying rod 3 slides through the upper end of the receiving tube 12, which has a corresponding sliding hole. The lower end of the applying rod 3 is fixed to the piston plate 5, and the elastic spring 4 is sleeved outside the applying rod 3. One end of the elastic spring 4 is fixed to the piston plate 5, and the other end is fixed to the inner end of the receiving tube 12. The claw 9 slides on the lower end of the piston plate 5. The lower end of the piston plate 5 is provided with a sliding rail, and the claw 9 slides on the movable rail. The claw 9 is fixedly connected to the push rod 6, and the receiving tube 12 is provided with a sliding groove 11 that matches the movement path of the push rod 6. There are two claws 9, connected by a spring 8. Fixed teeth are provided on opposite sides of each claw 9. A gripping block 7 is fixedly connected to the end of the push rod 6 facing away from the claw 9. The upper end of the applying rod 3 is provided with a pull plate 2.

[0031] The component connection relationship and working principle of the open-loop device are as follows:

[0032] like Figure 2 As shown, when the medical staff pulls the pull plate 2 upward, the force rod 3 is driven to move upward, thereby driving the piston plate 5 fixed to the lower end of the force rod 3 to move upward. Since the claw 9 is relatively fixed to the piston plate 5 in the vertical direction, it can drive the claw 9 to move upward, thereby pulling up the pull ring on the infusion bottle.

[0033] For the fixation of claw 9 and pull ring:

[0034] When the medical staff operates, the left hand is pressed against the grip block 7 and the grip block 7 is pressed inward, so that the pull ring sandwiched between the two claws 9 can be clamped and then moved upward.

[0035] When the medical staff releases the left hand, the two claws 9 return to their original positions. When the medical staff releases the right hand, the piston plate returns to its original position due to the elastic force of the elastic spring. And because the distance between the two claws 9 is adjustable, it can be used with pull rings of different thicknesses and sizes, and has greater adaptability.

[0036] like Figure 1 and Figure 2 As shown, a wristband 1 is provided on the outside of the accommodating cylinder 12. The palm of the right hand of the medical staff can contact the wristband 1, and the finger part applies a pulling force to the pull plate 2, which can achieve a leveraging operation, which is more efficient and labor-saving. Example

[0037] This embodiment makes the following improvements based on embodiment 1:

[0038] like Figure 4 As shown, the lower end of the accommodating cylinder 12 is provided with a fixing collar 10 adapted to the mouth of the reagent bottle.

[0039] like Figure 4 As shown, a U-shaped rod 13 is connected to the outside of the fixing collar 10 , and the free end of the U-shaped rod 13 is located below the claw 9 . Correspondingly, a through groove 14 is provided on the fixing collar 10 .

[0040] When the pull ring is pulled out, when the medical staff stops applying pressure to the grip blocks 7 on both sides with their left hand, the claws 9 no longer clamp the pull ring, and the pull ring will fall onto the U-shaped rod 13, making it easier for the medical staff to collect it.

[0041] However, although this method is convenient for medical staff to collect the removed pull ring, it also has disadvantages. For example, when the medical staff operates, the free end of the U-shaped rod 13 needs to pass through the hole on the pull ring in advance. In fact, as in the patent document in the background technology, there is also a positioning process, which increases the operation time of the medical staff. Therefore, in actual application, it is necessary to select the solution of embodiment 1 or embodiment 2 according to the situation.
