DETAILED DESCRIPTION

[0026] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] This embodiment provides a technical solution: an ampoule breaking aid, such as Figure 1-3 As shown, it includes a cylindrical shell 1 and a scratching mechanism 2. One end of the cylindrical shell 1 is a closed end and the other end is an open end. The outer structure of the cylindrical shell 1 is a truncated cone structure or a cylindrical structure. The interior thereof is a conical inner cavity adapted to the head of the ampoule bottle, which is set according to needs. For example, when it is a truncated cone structure, its large-diameter end is the open end. This embodiment is described with a truncated cone structure. A rubber sleeve 5 is fixed to the open end of the cylindrical shell 1, and the outer contour of the rubber sleeve 5 is in the same straight line as the outer contour of the cylindrical shell 1. The rubber sleeve 5 can be squeezed and deformed, which is convenient for operation. At the same time, it can protect the nurse's hands and prevent the sharp part of the broken ampoule from scratching the nurse's hands.

[0029] A first through hole 11 is formed on one side of the outer circumference of the cylindrical shell 1. The cylindrical shell 1 is used to cover the head of the ampoule. The inner cavity of the cylindrical shell 1 is a conical structure that fits the head of the ampoule.

[0030] The scratching mechanism 2 is fixed to the outer surface of the cylindrical shell 1 and corresponds to the first through hole 11; it includes an elastic plate 21, one end of the elastic plate 21 is fixed to the outer surface of the cylindrical shell 1, and the other end extends to the outside of the first through hole 11 and is installed with a cutter 22. The elastic plate 21 has the characteristic of being deformed by pressure. When not affected by external force, one end of its cutter 22 is in a state of being inclined outward. When the elastic plate 21 is squeezed to one side of the cylindrical shell 1 by the fingers, the cutter 22 will pass through the first through hole 11 and make contact with the outer surface of the neck of the ampoule bottle. Then, by rotating the cylindrical shell 1, the cutter 22 will scratch the neck of the ampoule bottle, and the cylindrical shell 1 can be broken along the scratch. Due to the existence of the scratch, the force for breaking the ampoule bottle is reduced, which reduces the labor intensity of the nurse. It should be noted that the opposite direction of the breaking force needs to be opposite to the scratch.

[0031] Furthermore, the tool 22 includes a tool holder 221, which is fixed to the end of the elastic plate 21 by bolts to facilitate replacement of the tool 22. A blade 222 is fixed to the inner end of the tool holder 221, and the inner end of the blade 222 has a groove portion 223. The groove portion 223 forms two cutting edges at the inner end of the blade 222. When the tool 22 contacts the neck of the ampoule bottle, both cutting edges can produce scratches at the same position on the neck of the ampoule bottle, making the ampoule bottle easier to break.

[0032] Furthermore, a conical inner cavity rubber cylinder 4 is provided on the inner surface of the cylindrical shell 1 for clamping the head of the ampoule bottle by extrusion deformation, and the conical inner cavity rubber cylinder 4 is provided with a second through hole corresponding to the first through hole 11 .

[0033] When breaking ampoules in batches, in order to increase efficiency, multiple ampoules can be taken out of the packaging box and placed upright on the table. When in use, one hand holds the auxiliary device, moves the auxiliary device and inserts the head of the ampoule bottle on the table into the cylindrical shell 1, and the conical inner cavity type rubber cylinder 4 will be squeezed and deformed. At this time, the force generated by the deformation of the conical inner cavity type rubber cylinder 4 will squeeze the head of the ampoule bottle and softly fix it (that is, the fixing reliability is low, but it can withstand the weight of the ampoule bottle and will not fall), so that the ampoule bottle can be lifted, and then the bottle body of the ampoule bottle can be pinched with the other hand to scratch and break the head of the ampoule bottle. During the scratching process, since the conical inner cavity type rubber cylinder 4 and the head of the ampoule bottle are softly fixed, as long as the nurse uses a certain rotational force, the conical inner cavity type rubber cylinder 4 and the ampoule bottle can rotate relative to each other.

[0034] In addition, the conical inner cavity type rubber tube 4 can also increase the buffer zone for the fixation between the cylindrical shell 1 and the head of the ampoule bottle, and a protective structure can be set on the inner surface of the conical inner cavity type rubber tube 4, such as annular anti-slip grooves or anti-slip points, to prevent the head of the ampoule bottle from being squeezed out of the conical inner cavity type rubber tube 4.

[0035] Example 2

[0036] This embodiment is further optimized based on the first embodiment, and the parts that are the same as the above technical solutions will not be repeated here. Figure 4-6 As shown, in order to better realize the present utility model, the following setting method is particularly adopted: since there is a certain resistance between the conical inner cavity type rubber cylinder 4 and the ampoule bottle, in order to save more effort during use, the conical inner cavity type rubber cylinder 4 is rotatably installed on the inner surface of the cylindrical shell 1 through a rotating member, so that when in use, there is no relative rotation between the conical inner cavity type rubber cylinder 4 and the head of the ampoule bottle.

[0037] Specifically, the rotating part includes a rotating cylinder 61, and the conical inner cavity rubber cylinder 4 is fixed to the inner surface of the rotating cylinder 61. In this embodiment, the second through hole is a long structure extending in the horizontal direction. A third through hole corresponding to the second through hole is opened on the rotating cylinder 61 to ensure that when the cylindrical shell 1 is rotated, the blade 222 will move in the second through hole without interfering with the cylindrical shell 1.

[0038] Furthermore, the inner surface of the cylindrical shell 1 is provided with two symmetrically arranged arc-shaped grooves 62, and an arc-shaped slider 63 fixed to the outer surface of the rotating cylinder 61 is slidably provided in the two arc-shaped grooves 62. The length of the arc-shaped slider 63 is less than the length of the arc-shaped groove 62. The sliding stroke of the arc-shaped slider 63 in the arc-shaped groove 62 is the relative rotation stroke of the cylindrical shell 1 and the conical inner cavity rubber cylinder 4. During this stroke, the blade 222 passes through the second through hole and the third through hole and makes horizontal arc motion therein.

[0039] During use, the head of the ampoule can be inserted into the inner cavity of the conical inner cavity rubber cylinder 4, and the cylindrical shell 1 can be rotated to the starting point of one end of the stroke. The rotating cylindrical shell 1 is moved to the end point of the other end, and the neck of the ampoule can be scratched by the blade 222. It should be noted that during this process, the conical inner cavity rubber cylinder 4 can be clamped or not clamped on the head of the ampoule. There is no need to specifically clamp the conical inner cavity rubber cylinder 4 on the head of the ampoule. It is only necessary for the blade 222 to move relative to the head of the ampoule.

[0040] Example 3

[0041] This embodiment is further optimized based on the first or second embodiment, and the same parts as the above technical solutions will not be repeated here. Figure 1 and Figure 2 As shown, in order to better realize the present invention, the following setting method is particularly adopted: after the head of the ampoule bottle is broken off, the head of the ampoule bottle is likely to be restricted inside the conical inner cavity type rubber tube 4 due to the force of the conical inner cavity type rubber tube 4. In order to remove the head of the ampoule bottle from the conical inner cavity type rubber tube 4, a pushing mechanism 3 is provided at the closed end of the cylindrical shell 1. The pushing mechanism 3 includes a slide rod 33 slidably mounted on the closed end of the cylindrical shell 1. A push block 31 is fixed at one end of the slide rod 33 extending into the cylindrical shell 1, and a spring 32 is installed between the push block 31 and the inner top of the cylindrical shell 1. When not subject to other forces, the spring 32 will pull the slide rod 33 outward by a certain size. A pressing block 34 is fixed at the other end of the slide rod 33 for the nurse to press.

[0042] When in use, the push block 34 is pressed toward one side of the cylindrical shell 1, and the push block 31 can push the head of the ampoule bottle out of the inner cavity of the conical inner cavity rubber cylinder 4 and drop it, and stretch the spring 32. When the push block 34 is released, the slide rod 33 will return to its original position due to the force of the spring 32, which brings convenience to the nurse.

[0043] The above are only preferred embodiments of the present invention and are intended to be illustrative rather than restrictive. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the embodiments within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
