[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2 A device for breaking an ampoule comprises an outer conical shell 1, a ball head structure 2 integrally arranged at the top of the outer conical shell 1, an outer conical cavity 3 arranged inside the outer conical shell 1 and having an open bottom, a fixing sleeve 7 placed on the outer surface of the bottom of the outer conical shell 1, and a longitudinal connecting rod 8 fixedly installed at the bottom of the fixing sleeve 7. The outer conical shell 1 and the ball head structure 2 need to be designed to conform to the size of a human palm. When the center of the palm holds the ball head structure 2, the index finger or middle finger of the medical staff needs to be able to be inserted into the finger ring 99, and the index finger or middle finger needs to have the ability to drive the finger ring 99 to move.

[0020] For flexible snap-on capability on the top of the ampoule neck, see Figure 1 and Figure 2, it is necessary to set an inner conical shell 4, which is installed in the inner circumferential surface of the outer conical cavity 3 through a bearing, and the inner conical shell 4 is provided with an inner conical cavity 5 with an opening at the bottom end, and the inner conical shell 4 is adhered with a conical cushion 6 on the inner surface of the inner conical cavity 5. In order to achieve the wrapping clamping ability of the bottleneck of the ampoule bottle, it is necessary to make the interior of the conical cushion 6 a hollow structure, and the bottom diameter of the hollow structure is larger than the top diameter, and the bottom diameter of the hollow structure is larger than the structural size of the bottom of the bottleneck of the ampoule bottle, the top diameter of the bottom of the hollow structure is larger than the structural size of the bottom of the bottleneck of the ampoule bottle, and the top diameter of the bottom of the hollow structure is larger than the top diameter of the bottom of the bottleneck of the ampoule bottle. The caliber of the outer conical shell 1 is smaller than the structural size of the bottom of the neck of the ampoule bottle. The neck of the ampoule bottle is inserted upward into the hollow structure of the conical buffer pad 6 until the top outer surface of the neck of the ampoule bottle is tightly wrapped inside the conical buffer pad 6 to achieve the positioning of the top of the neck of the ampoule bottle. At the same time, an upward grip is applied to the body of the ampoule bottle to prevent the ampoule bottle from rotating. When the outer conical shell 1 rotates, it can drive the grinding wheel 96 to rotate around the neck of the ampoule bottle, thereby achieving the movable sleeve placement capability of the top of the neck of the ampoule bottle.

[0021] To achieve a constant grinding pressure, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is necessary to set up an elastic grinding mechanism 9, which is provided with a grinding wheel 96 pointing to the axis of the conical buffer pad 6 and a coil spring 98 that can generate elastic pressure on the grinding wheel 96 toward the axis of the conical buffer pad 6. The index finger or middle finger of the medical staff needs to drive the finger ring 99 to move outward, and the finger ring 99 will drive the movable block 94 and the grinding wheel 96 away from the axis of the conical buffer pad 6. The medical staff can insert the bottleneck of the ampoule bottle into the interior of the conical buffer pad 6, and then release the force on the finger ring 99. Under the elastic action of the coil spring 98, the edge of the grinding wheel 96 will contact the bottleneck of the ampoule bottle, and then hold the bottle body of the ampoule bottle with one hand, and rotate the ball head structure 2 with the other hand. Note that the range of rotation is within 180°. After grinding, remove the device and you can pry open the bottleneck of the ampoule bottle with both hands.

[0022] For the specific structure of the elastic grinding mechanism 9, please refer to Figure 3 and Figure 4, including a transverse hollow rod 91, the circumferential surface of the transverse hollow rod 91 is provided with a rod body fixing groove 92 for fixing and installing the bottom end rod body of the longitudinal connecting rod 8, the interior of the transverse hollow rod 91 is provided with a transverse component movable cavity 93, and the transverse hollow rod 91 is provided with a movable block 94 that can move laterally inside the transverse component movable cavity 93. In order to prevent the relative rotation between the components, it is necessary to make the structural shape of the cross section of the transverse component movable cavity 93 consistent with the structural shape of the cross section of the movable block 94, both of which are polygonal structures, and the structural dimensions of the cross section of the transverse component movable cavity 93 match the structural dimensions of the cross section of the movable block 94, and the movable block 94 is facing the axis of the conical buffer pad 6. A No. 1 telescopic rod 95 is fixedly installed on the end face of the line, which passes through the corresponding end face of the transverse hollow rod 91. A No. 2 telescopic rod 97 which passes through the other end face of the transverse hollow rod 91 is fixedly installed on the other end of the movable block 94. A grinding wheel 96 is fixedly installed on the end of the No. 1 telescopic rod 95. In order to have sufficient movable stroke, it is necessary to make one end of the movable block 94 abut against one end of the movable cavity 93 of the transverse component close to the axial center line of the conical buffer pad 6, and the grinding wheel 96 is located on the axial center line of the conical buffer pad 6. A finger ring 99 is fixedly installed on one end of the No. 2 telescopic rod 97. A coil spring 98 in a compressed state is placed on the outer periphery of the shaft body of the No. 2 telescopic rod 97 located inside the movable cavity 93 of the transverse component.

[0023] When in use, the medical staff holds the ball head structure 2 with the center of the palm, and inserts the index finger or middle finger into the inside of the finger ring 99. The index finger or middle finger needs to drive the finger ring 99 to move outward, and the finger ring 99 will drive the movable block 94 and the grinding wheel 96 away from the axis of the conical buffer pad 6. The medical staff inserts the bottleneck of the ampoule bottle into the inside of the conical buffer pad 6, and then releases the force on the finger ring 99. Under the elastic action of the coil spring 98, the edge of the grinding wheel 96 will contact the bottleneck of the ampoule bottle. Then hold the bottle body of the ampoule bottle with one hand and rotate the ball head structure 2 with the other hand. Note that the rotation range is within 180°, then the grinding wheel 96 will be opposite. After grinding, remove the device and you can pry open the bottleneck of the ampoule bottle with both hands.
