Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a device for removing a cap of an infusion bottle. Background Art

[0002] When hospital nurses infuse patients, they need to use corresponding infusion bottles. There will be end caps on the infusion bottles. When using, the staff needs to remove the end caps on the infusion bottles before they can further connect the infusion tubes and dispense medicines. When removing the end caps of the infusion bottles, they often need to use corresponding removal devices;

[0003] Most of the existing removal devices used by medical staff to remove the bottle caps on infusion bottles are simple scissors. The staff holds the infusion bottle in one hand and the scissors in the other hand, and then uses the scissors to remove the end cap of the infusion bottle. However, there are dangers in the operation process, and operating errors can easily cause the scissors to injure the staff's hands. Therefore, we propose an infusion bottle cap removal device.

[0032] In actual use, when removing the end cap on the glass infusion bottle, the end block 13 is attached to the top of the end cap of the infusion bottle, and the limiting plate 12 is stuck in the gap on one side of the end cap of the infusion bottle, and then the device can be manually pried to make the limiting plate 12 lift the end cap to make it detach from the infusion bottle. The operation is convenient and quick, which helps to avoid the danger of scissor operation in the past. At the same time, when lifting the end cap of the infusion bag, the fixing column 2 can be inserted into the plastic ring of the end cap of the infusion bag, and then the outer wall of the fixing column 2 is attached to the end of the infusion bag, and the contact point between the fixing column 2 and the end of the infusion bag is used as a fulcrum to forcefully move the end plate 1, so that the plastic ring can be pried to limit the end cap and the plastic ring can be separated from the infusion bag, so that the device can be used with different infusion containers, thereby improving the adaptability of the device;

[0033] Furthermore, a plurality of evenly distributed grooves 21 are provided at the bottom of the fixing column 2. When the fixing column 2 contacts the end of the infusion bag, the side of the end of the infusion bag is clamped in the groove 21, so that the operation of lifting the plastic ring and the end cover of the infusion bag is convenient and quick, and sliding is avoided;

[0034] like Figure 1 and 3 As shown; a push rod 14 is movably passed through the top of the end plate 1, a pressure block 15 is fixed on the top of the push rod 14, the fixed plate 11 is a hollow structure, the push rod 14 is inserted into the inner cavity of the fixed plate 11 and is fixedly connected with a first wedge block 18, a second wedge block 19 is fitted at the bottom of the first wedge block 18, and a connecting rod 3 is movably connected to the side wall of the second wedge block 19, and the connecting rod 3 movably passes through the fixed plate 11 and the limit plate 12 and is fixedly connected to one end of the movable plate 17;

[0035] When the prying device is used to lift the end cap of the infusion bottle, the pressing block 15 is held and pressed, thereby driving the push rod 14 to push the first wedge block 18 downward, thereby pushing the second wedge block 19 to move to one side, thereby pushing the connecting rod 3 and the movable plate 17 to move outward, so that when the end cap is lifted, the movable plate 17 can extend into the end cap, so that the limit position is more stable when lifting, and there is no slipping when lifting;

[0036] Furthermore, a sliding groove is provided on a side wall of the second wedge block 19 corresponding to the connecting rod 3, and the end of the connecting rod 3 is slidably inserted into the sliding groove, so that when the second wedge block 19 moves to push the second connecting rod 3 to move, there is no space obstacle;

[0037] Furthermore, a limiting slide groove is provided in the inner cavity of the notch 16, and an adapted limiting slider 4 is inserted into the inner cavity of the limiting slide groove. The bottom of the limiting slider 4 is fixedly connected to the movable plate 17, and the limiting slider 4 can be used to limit the moving track of the movable plate 17, thereby ensuring the stable movement of the movable plate 17 and preventing the movable plate 17 from escaping from the notch 16;

[0038] It is worth mentioning that a spring 41 is fixedly connected to one side wall of the limit slide block 4, and the outer end of the spring 41 is fixedly connected to the inner wall of the limit slide groove, so that when the pressure block 15 is released, the limit slide block 4 can be pushed to reset under the action of the reverse thrust of the spring 41, thereby resetting the second wedge block 19, and then the first wedge block 18 pushes the push rod 14 and the pressure block 15 to reset, so as to facilitate reuse.

[0039] The implementation principle of the infusion bottle cap removal device of the present application is as follows: in actual use, when the end cap on the glass infusion bottle is removed, the end block 13 is attached to the top of the end cap of the infusion bottle, and the limiting plate 12 is stuck in a side gap of the end cap of the infusion bottle, and then the device is manually pried to make the limiting plate 12 lift the end cap to make it detach from the infusion bottle. The operation is convenient and quick, which is helpful to avoid the danger of scissors operation in the past. When the prying device lifts the end cap of the infusion bottle, the pressing block 15 is hand-held to press the push rod 14, thereby driving the first wedge block 18 to descend, thereby pushing the second wedge block 19 to move to one side, thereby pushing The connecting rod 3 and the movable plate 17 move outward, so that the movable plate 17 can extend into the interior of the end cover when the end cover is tilted, so that the limit is more stable when tilted, and there is no slippage when tilted. At the same time, when the end cover of the infusion bag is tilted, the fixed column 2 can be inserted into the plastic ring of the end cover of the infusion bag, and then the outer wall of the fixed column 2 is made to fit the end of the infusion bag.
