Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a cartridge and a processing device for medicine. Background Art

[0002] In the process of processing powdered medicine into medicines with a certain shape, one of the steps is: the ground medicine powder is loaded into a barrel, and the barrel serves as a transfer and receiving component to transfer the medicine powder to a pressing tool, and then the pressing tool presses the medicine powder.

[0003] The structure of the barrel is as follows: a breather is provided inside the barrel, which is used to balance the pressure inside and outside the barrel. When the barrel is transferred to the pressing tooling, the breather needs to be opened to make the pressure inside the barrel consistent with the pressure outside the barrel, and then the powder in the barrel is pumped into the pressing tooling by the pump body.

[0004] However, the above-mentioned existing structure has the following disadvantages: the respirator is directly built into the barrel, and since the barrel contains powdered medicine, when the pump body is used to extract it to the pressing tooling, the medicine powder will directly enter the respirator, which will not only cause waste of medicine powder, but also cause the respirator to malfunction due to the entry of medicine powder. If there is a lot of medicine powder in the respirator, the respirator needs to be replaced, which will also increase production costs.

[0005] Therefore, there is an urgent need for a barrel and a processing device for medicines to solve the technical problems existing in the prior art to a certain extent. Utility Model Content

[0044] Example 1

[0045] The following combination Figure 1-Figure 4 As shown, a cartridge provided by the present application is described in detail.

[0046] The present application provides a cartridge that can prevent drug powder from entering the respirator, thereby enabling the respirator to function normally without wasting drug powder. The specific structure of the cartridge is described as follows:

[0047] In this embodiment, a barrel is provided, which includes a barrel 1 and a respirator, wherein an end cover 2 is provided on the barrel 1. Further, the end cover 2 is connected to the barrel 1 by a snap-fit, so that the end cover 2 can be opened or fastened to the barrel 1, or the end cover 2 is connected to the barrel 1 by a bolt. In addition, a connecting hole is provided at the center of the end cover 2, and an air duct 3 is provided on the connecting hole, and the air duct 3 can connect to the gas inside and outside the barrel 1. The respirator is arranged inside the barrel 1 and has a breathing tube on the respirator. When the end cover 2 is fastened to the barrel 1, the air duct 3 can just dock with the breathing tube. When the respirator is started, the air pressure inside the barrel 1 can be balanced with the air pressure outside the barrel 1 through the docking and diversion effect of the breathing tube and the air duct 3. The above structure is a prior art, which is understood by those skilled in the art. The present application is improved on the basis of the existing structure, and the specific structure is as follows:

[0048] In this embodiment, the barrel further includes a support assembly and a filter assembly; the support assembly includes a support portion 7 having a mounting cavity 4, the respirator is disposed in the mounting cavity 4, and the breathing tube can extend out of the mounting cavity 4. The support portion 7 is used to fix the respirator.

[0049] Specifically, the filter assembly includes a filter portion 9 and a locking portion connected to the filter portion 9; the filter portion 9 is sleeved on the support assembly, that is, the filter portion 9 wraps the support assembly, and because the respirator is inside the support assembly, the filter portion 9 also wraps the respirator at the same time, so that the respirator is not in direct contact with the outside world, cutting off the possibility of the respirator contacting the outside world.

[0050] Specifically, the locking portion is locked to the outer wall of the breathing tube; during actual use, the air guide tube 3 and the breathing tube 8 are connected together, and then the locking portion is locked to the outer wall of the breathing tube 8. This does not affect the normal use of the respirator and also ensures that the respirator is not contaminated by material powder.

[0051] During actual use, the ground powder is first loaded into the barrel (the end cap 2 needs to be removed from the barrel 1 before loading). The barrel serves as a transfer and holding component to transfer the powder to the press-fitting tool (the press-fitting tool is not within the scope of protection of this application and is irrelevant to this application, so its structure will not be described in detail). When it reaches the press-fitting tool, first, the support assembly and the respirator are connected to the end cap. Specifically, the breathing tube and the airway tube are connected together by a clamp. Since the respirator is set in the support assembly, the support assembly and the respirator can be connected to the end cap by a clamp 16; further, the clamp is a clamp, which is a prior art that can be understood by those skilled in the art and will not be elaborated on here. Then, the respirator is turned on to make the pressure inside the barrel consistent with the pressure outside the barrel; then, the powder in the barrel is pumped to the press-fitting tool using a pump.

[0052] In summary, since the respirator is inside the support assembly, it will not come into direct contact with the medicine powder, which means that the medicine powder will not enter the respirator, and will not affect the normal use of the respirator. The respirator will not be unable to work normally due to the entry of medicine powder. In addition, the medicine powder that passes through the filter part 9 and enters the interior of the filter part 9 can be back-flushed back into the barrel 1, which will not cause waste of medicine powder.

[0053] In this embodiment, further, the supporting portion 7 is a supporting tube 10 .

[0054] Specifically, the support tube 10 is surrounded by a mounting cavity.

[0055] Further, combined with Figure 1 As shown, the support tube 10 includes an upper support plate 12, a lower support plate 13 and a support column 14; the upper support plate 12 and the lower support plate 13 are both circular and have the same diameter, and the support column 14 is supported between the upper support plate 12 and the lower support plate 13. Furthermore, there are multiple support columns 14, and the multiple support columns 14 are arranged at equal intervals along the circumference of the upper support plate 12, so that the support tube 10 is a cylindrical hollow structure.

[0056] Furthermore, the upper support plate 12 is close to the end cover 2 , and an extension area 15 is formed in the middle of the upper support plate 12 , and the breathing tube extends out from the extension area 15 .

[0057] In this embodiment, further, the diameter of the support tube 10 is set between 160 mm and 200 mm, preferably, the diameter of the support tube 10 is 180 mm. The height of the support tube 10 is set between 140 mm and 180 mm, preferably, the height of the support tube 10 is 160 mm.

[0058] In this embodiment, the upper support plate 12, lower support plate 13, and support columns 14 are all made of 304 stainless steel. This 304 stainless steel is corrosion-resistant, preventing the upper support plate 12, lower support plate 13, and support columns 14 from being corroded by the drug powder to a certain extent. Furthermore, this 304 stainless steel is heat-resistant, ensuring the structural stability of the upper support plate 12, lower support plate 13, and support columns 14 even when the barrel operates at relatively high temperatures. Furthermore, this 304 stainless steel is also highly machinable, making it easy to cut and connect.

[0059] In this embodiment, further, the filter portion 9 is a filter bag, and the locking portion is a drawstring; the drawstring is arranged on a side of the filter bag close to the end cover 2; the filter bag is surrounded by a sleeve cavity, and the support assembly is arranged in the sleeve cavity.

[0060] The structure in which the drawstring and the filter bag are combined together can be understood as a bag body with a drawstring, which is a relatively common structure and can be understood by those skilled in the art, and will not be described in detail here.

[0061] It is worth noting that the filter assembly is not limited to the aforementioned structure in which the drawstring and filter bag are combined. A zipper and filter bag can also be combined, i.e., a zipper is provided on the side of the filter bag near the end cap 2. When the filter bag needs to be sealed, the zipper can be closed. Alternatively, a pattern sticker can be used, i.e., a Velcro sticker (including a fleece side and a hook side) is provided on the side of the filter bag near the end cap 2. Specifically, the side of the filter bag near the end cap 2 has two edges, one of which has a hook side and the other has a fleece side. When the filter bag needs to be sealed, the fleece side is attached to the hook side.

[0062] In this embodiment, further, in order to ensure that the filter bag can completely cover the support assembly, the size of the filter bag is set to be larger than the size of the support assembly.

[0063] Example 2

[0064] The present application also provides a drug processing device comprising the above-mentioned barrel, thereby having all the beneficial effects of the above-mentioned barrel.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
