[0030] Please see Figure 1-3 This embodiment provides an ampoule-breaking device that can protect both hands. It includes: a handle body 1, on which a groove 111 for accommodating an ampoule bottle is provided, and a clamping member 13 is provided in the groove 111; a grinding and cutting assembly 2, which includes a cutting head 21 and a control rod 22, one end of which is rotatably mounted on the handle body 1, and the cutting head 21 is mounted on the other end of the control rod 22, with the cutting head 21 facing the groove 111; and a pusher assembly 3, which includes a slider 31 and a handle 32, the slider 31 being slidably mounted on the handle body 1, the sliding path of which passes above the groove 111, and the handle 32 being rotatably mounted on the handle body 1, the rotation of which drives the slider 31 to move.

[0031] Specifically, when it is necessary to break open the ampoule, first place the ampoule body into the groove 111 of the handle body 1. The clamping member 13 in the groove 111 and the groove 111 itself clamp and fix the ampoule body. Then, using the grinding and cutting assembly 2, move the control lever 22. The cutting head 21 at the end of the control lever 22 passes through the connection between the ampoule head and the body on the groove 111 to grind it. Push the handle 32 of the pusher assembly 3, and then rotate the handle 32. The handle 32 drives the slider 31 to move towards the groove. Pushing the ampoule head out of the groove 111 from above pushes the ampoule body into place. Since the ampoule body is fixed in the groove 111, the head is pushed out. Then, use a syringe to draw up the medication directly from the ampoule. After that, pour out the ampoule. The device has a simple structure. After placing the ampoule in the groove 111, medical staff do not need to touch the ampoule directly with their hands. This avoids injury to medical staff from sharp edges or debris when opening the ampoule and avoids cross-infection caused by opening the ampoule.

[0032] In some possible implementations, the grip body 1 is pistol-shaped, and the grip body 1 includes a barrel 11 and a handle 12. The handle 12 is connected to the rear end of the barrel 11. The front end of the barrel 11 is provided with a notch 112, and a groove 111 is provided in the notch 112. The groove 111 is adapted to the body of the ampoule.

[0033] Specifically, the pistol-shaped grip body 1 is more convenient for medical staff to hold. The groove 111 for holding the ampoule is located at the barrel 11 at the handle 12. The structure is more reasonable and convenient to use. The front end of the barrel 11 is provided with a notch 112. The ampoule is divided into a body and a head. Most of the body of the ampoule is accommodated in the groove 111, and the head extends out of the groove 111. A part of the head is located in the notch 112, and the upper part of the head is located on the notch 112 and extends out of the upper surface of the barrel 11.

[0034] In some possible embodiments, a groove 113 is formed along the top of the barrel 11, and a slider 31 is disposed within the groove 113. A grip 32 is rotatably mounted at the connection between the barrel 11 and the handle 12, with the grip 32 and handle 12 arranged at an angle. A telescopic spring 114 is provided between the grip 32 and handle 12. A drive groove 115 is formed inside the barrel 11, with the top of the drive groove 115 communicating with the groove 113. A drive rod 116 is provided on the grip 32 and extends into the drive groove 115. The drive rod 116 is connected to the bottom of the slider 31 via a connecting rod 117. A pusher block 33 is provided on the slider 31. The pusher block 33 is made of hard rubber and is L-shaped, with the vertical rod of the pusher block 33 facing the notch 112.

[0035] Specifically, the slider 31 is set inside the groove 113, and the pusher block 33 is set on the slider 31. The pusher block 33 has a shorter required movement path. When the slider 31 is at the rear end of the groove 113, the pusher block 33 only needs to be flush with the notch 112. The distance between the groove 113 and the length of the notch 112 is the same. The end of the grip 32 away from the barrel 11 has a longer movement distance. The rotational connection between the grip 32 and the drive rod 116 relative to one end of the grip 32 forms a lever. When the medical staff holds the grip 32 and the handle 12 and squeezes the grip 32 toward the handle 12, the drive rod 116 moves in the opposite direction of the grip 32. The drive rod 116, in conjunction with the connecting rod 117, drives the slider 31 toward the bottle head. The connecting rod 117 and the drive rod 116, as well as the bottom of the slider 31, are all rotatably connected. After the bottle head is pushed out and the hand is released, the telescopic spring 114 pushes the grip 32 back to its original position.

[0036] In some possible implementations, a transverse through groove 118 is provided in the middle of the barrel 11. The through groove 118 communicates with the notch 112. The connection between the through groove 118 and the notch 112 is located at the opening of the groove 111. One end of the control rod 22 is rotatably installed in the through groove 118, and the other end of the control rod 22 faces the notch 112. The cutting head 21 extends out of the through groove 118 and is adjacent to the opening of the groove 111.

[0037] Specifically, the transverse groove 118 in the middle of the barrel 11 is used to accommodate the grinding and cutting component 2. The groove 118 leads to the notch 112. The grinding and cutting component 2 in the groove 118 can extend out of the notch 112 and be close to the connection between the body and the head of the ampoule. One end of the control lever 22 is rotatably connected to the groove 118 away from the notch 112. The cutting head 21 extends out of the groove 118 and is located in the notch 112, above the groove 111, close to the connection between the body and the head of the ampoule. When the control lever 22 is moved, the cutting head 21 is driven to grind towards the connection between the body and the head of the ampoule.

[0038] In some possible implementations, a triangular-shaped housing 23 is mounted on the control lever 22. The housing 23 is adapted to the through slot 118 and is snapped into the through slot 118. The housing 23 rotates with the control lever 22. The cutting head 21 is arc-shaped and made of silicon carbide.

[0039] Specifically, the housing 23 on the control lever 22 provides a point of force for medical personnel to move the control lever 22. The housing 23 is triangular, with one corner of the triangular housing 23 located at the rotating end of the control lever 22. When the medical personnel press the housing 23, when one side of the housing 23 is aligned with the side of the barrel 11 of the through groove 118, the other side of the housing 23 extends out of the other side of the through groove 118 and out of the other side of the barrel 11, which limits the rotation range of the control lever 22 to a certain extent. Pressing the housing 23 again to extend out of the through groove 118 can move the rotating lever again, thereby driving the cutting head 21 to glide across the ampoule. The cutting head 21 only needs to glide across the ampoule. The limitation of the rotation range of the rotating lever by the housing 23 can meet the usage requirements. The arc-shaped cutting head 21 will not cause the ampoule to break when scratching it. At the same time, the silicon carbide material is the material of the abrasive wheel, which has a better effect on thinning the ampoule.

[0040] In some possible embodiments, the clamping member 13 includes two arc-shaped rubber pads 131 disposed on the inner wall of the groove 111. A bottle opener 4 is provided on the barrel 11. Both the barrel 11 and the handle 12 are made of plastic.

[0041] Specifically, an arc-shaped rubber pad 131 is set in the groove 111. The rubber material has a certain degree of softness. When the pusher assembly 3 pushes the bottle head, the bottle body will also receive the pushing force. The rubber material has a buffering effect to avoid wear on the bottle body. The bottle opener 4 can be used to open the aluminum cap of the medicine bottle, improving the practicality of the device. The plastic material is more lightweight.
