DETAILED DESCRIPTION

[0034] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0035] like Figure 1-8As shown, this embodiment provides a medicine grinding feeder, which includes a barrel 100 and a core rod 200. The barrel 100 is a hollow structure with two ends open, and the first end of the barrel 100 can be connected to the feeder assembly (not shown in the figure), the core rod 200 has a certain length, and the first end of the core rod 200 can extend from the second end of the barrel 100 into the barrel 100. Further, a first grinding surface 112 is provided in the barrel 100, and the first grinding surface 112 is connected to the feeder assembly, and a second grinding surface 211 is provided on the first end of the core rod 200.

[0036] When using the medicine grinding feeder in this embodiment, first take out the core rod 200 from the barrel 100, put the solid medicine into the barrel 100, connect the first end of the barrel 100 to the feeder assembly, and then extend the first end of the core rod 200 from the second end of the barrel 100 into the barrel 100, so that a grinding space 300 can be formed between the first grinding surface 112 and the second grinding surface 211, and the solid medicine is in the grinding space 300. Since the first grinding surface 112 is connected to the feeder assembly, the grinding space 300 can be connected to the feeder assembly. The user can select or combine two grinding methods to make the first grinding surface 112 and the second grinding surface 211 move relative to each other to achieve grinding of solid medicines. First, by pushing and pulling the core rod 200 back and forth, the first grinding surface 112 and the second grinding surface 211 squeeze the solid medicine, so that the solid medicine is continuously broken and finally forms powder. Second, a force is applied to the core rod 200 so that the second grinding surface 211 has a tendency to move toward the first grinding surface 112, and at the same time, the core rod 200 is rotated circumferentially, thereby achieving the extrusion and grinding of the solid medicine by the first grinding surface 112 and the second grinding surface 211, so that the solid medicine is continuously broken and finally forms powder. Third, the solid medicine is ground by a combination of the above two grinding methods, which will not be repeated.

[0037] Since the first grinding surface 112 is connected to the feeder assembly, the grinding space 300 is connected to the feeder assembly, so that when the first grinding surface 112 and the second grinding surface 211 grind the solid medicine into powder, the core rod 200 further pushes, so that the second grinding surface 211 moves toward the first grinding surface 112 and finally fits, and then, under the push of the second grinding surface 211, the powder formed by the solid medicine in the grinding space 300 can be pushed toward the feeder assembly, and then directly delivered to the patient's stomach through the feeder assembly. It should be noted that in some cases, after the solid medicine is ground into powder, the core rod 200 can also be taken out of the cylinder 100, and warm water is added to the cylinder 100, and then the core rod 200 is re-installed into the cylinder 100, and the push of the core rod 200 can achieve warm water delivery. In some cases, multiple solid medicines need to be ground and fed. In this case, different types of solid medicines can be processed separately, that is, one solid medicine is ground and delivered to the patient's stomach through the feeder component, and then another solid medicine is ground and fed. This can better avoid mixing and contamination between different medicines and avoid affecting the effectiveness of the medicines.

[0038] It is worth mentioning that, since the solid medicine in this embodiment is ground in the grinding space 300 formed by the barrel 100, the first grinding surface 112 and the second grinding surface 211, it can better avoid the splashing of the solid medicine during the grinding process. At the same time, the grinding space 300 is connected to the feeder assembly. After the solid medicine is ground, the core rod 200 can directly push the powder formed by the solid medicine into the feeder assembly, avoiding the need to transport the powder, better avoiding the loss of the medicine, and making it possible to more accurately control the amount of medicine.

[0039] In some embodiments, a first extrusion platform 110 is provided on the end of the first end of the cylinder 100, and the first extrusion platform 110 can seal the first end of the cylinder 100; a through hole 111 is provided on the first extrusion platform 110 and passes through the first extrusion platform 110, and the first end of the cylinder 100 is connected to the feeder assembly through the through hole 111, wherein the side wall of the first extrusion platform 110 facing the second end of the cylinder 100 forms the above-mentioned first grinding surface 112.

[0040] It is understandable that, when the first end of the core rod 200 is extended from the second end of the barrel 100 into the barrel 100, the grinding space 300 formed by the barrel 100, the first grinding surface 112 and the second grinding surface 211 can be connected to the feeder assembly through the through hole 111 on the first extrusion platform 110. After the first grinding surface 112 and the second grinding surface 211 grind the solid medicine into powder, the medicine can be directly pushed into the feeder assembly through the through hole 111 on the first extrusion platform 110 by the core rod 200, thereby avoiding the need to transport the powder, preferably avoiding the loss of the medicine, and enabling more accurate control of the amount of medicine.

[0041] In some embodiments, in the direction from the second end of the barrel 100 to the first end of the barrel 100, the first extrusion surface tends to bulge in the direction away from the second end of the barrel 100. In more detail, the first grinding surface 112 around the through hole 111 to the first grinding surface 112 around the inner side wall of the barrel 100 tends to extend in the direction gradually approaching the second end of the barrel 100. When the barrel 100 is placed vertically so that the first end of the barrel 100 faces downward, the powder formed by the solid drug on the first grinding surface 112 tends to move toward the through hole 111.

[0042] It can be understood that after the solid medicine is put into the barrel 100, the first end of the core rod 200 is extended into the barrel 100, and the core rod 200 is rotated and pushed so that the core rod 200 pushes the solid medicine to the first grinding surface 112 through the second grinding surface 211 and grinds it. During this process, the barrel 100 can be rotated to a vertical state so that the first end of the barrel 100 faces downward, so that the solid medicine between the first grinding surface 112 and the second grinding surface 211 can roll on the first grinding surface 112 to the middle position of the first grinding surface 112, and then the solid medicine can be ground again by the movement of the second grinding surface 211.

[0043] It is worth mentioning that, by designing the shape of the first grinding surface 112, the first grinding surface 112 can play a certain guiding role on the solid medicine or the powder formed by the solid medicine. By rotating the cylinder 100 to a vertical state so that the first end of the cylinder 100 faces downward, the solid medicine can be moved to the middle position of the first grinding surface 112 under the action of gravity through the guidance of the first grinding surface 112, so that the second grinding surface 211 can fully extrude and grind the solid medicine with the first grinding surface 112, so as to better ensure the effect of grinding the solid medicine and form uniform particles of the solid medicine; of course, when the solid medicine is formed into powder, the first grinding surface 112 can also guide the powder, so that when the core rod 200 pushes, the powder can move toward the direction of the through hole 111, and then be pushed into the feeder assembly by the core rod 200 and directly reach the patient's stomach, which is more efficient and effective.

[0044] In some embodiments, a grinding groove 112a is formed inwardly on the first grinding surface 112, and the number of the grinding grooves 112a is multiple. It is understandable that solid medicines have a certain hardness, and a large extrusion force is required to crush the solid medicines, which will cause inconvenience in use. In this embodiment, after the solid medicines are put into the cylinder 100, the first end of the core rod 200 is extended into the cylinder 100, so that the second grinding surface 211 moves close to the first grinding surface 112. During this process, the second grinding surface 211 will push the solid medicine toward the first grinding surface 112 until the solid medicine contacts the first grinding surface 112. Since the first grinding surface 112 is provided with multiple grinding grooves 112a, the surface of the first grinding surface 112 is uneven. When the core rod 200 is passed through, the solid medicine is crushed. 00When the second grinding surface 211 continues to be pushed to move closer to the first grinding surface 112, the solid medicine will be squeezed against the side edges of the grinding groove 112a, and then cracks will appear at the corresponding positions of the solid medicine under the action of the side edges of the grinding groove 112a, thereby crushing the solid medicine. Thereafter, the core rod 200 is moved a certain distance away from the first end of the cylinder 100, and the cylinder 100 is shaken to change the position of the solid medicine. The core rod 200 is pushed again to move the second grinding surface 211 closer to the first grinding surface 112, thereby realizing secondary crushing of the solid medicine. After repeating the above operation, the solid medicine can be formed into powder.

[0045] It can be understood that, by setting up multiple grinding grooves 112a, the user can apply a smaller thrust to the core rod 200, and the solid medicine can be crushed under the cooperation of the side edges of the grinding groove 112a and the second grinding groove 112a, which can better achieve the effect of saving labor and make the crushing of solid medicine more convenient and quick.

[0046] In some embodiments, a plurality of grinding blocks 211a are provided on the second grinding surface 211. The number of the grinding blocks 211a is plural, and preferably the number of the grinding blocks 211a corresponds to the number of the grinding grooves 112a. The shapes and sizes of the grinding blocks 211a and the grinding grooves 112a are also consistent, and the positions of the grinding blocks 211a correspond one-to-one to the positions of the grinding grooves 112a, so that when the second grinding surface 211 is close to the first grinding surface 112, the grinding blocks 211a can extend into the corresponding grinding grooves 112a, thereby allowing the first grinding surface 112 to fit the second grinding surface 211.

[0047] By arranging the grinding block 211a on the second grinding surface 211, the side edge of the grinding block 211a can also cooperate with the first grinding surface 112 or the grinding groove 112a to squeeze the solid medicine, so that cracks appear at the corresponding position of the solid medicine, thereby achieving the crushing of the solid medicine, further improving the labor-saving effect, and making the crushing of the solid medicine more convenient and quick.

[0048] It is particularly important to note that the grinding block 211a can fully fill the grinding groove 112a. When the solid medicine is extruded and ground, the grinding block 211a can extend into the grinding groove 112a, so that the grinding block 211a can extrude and grind the solid medicine in the grinding groove 112a, thereby making the grinding of the solid medicine more sufficient and better improving the grinding effect of the solid medicine.

[0049] In some embodiments, the cross-sectional shapes of the grinding groove 112 a and the grinding block 211 a are both conical.

[0050] It should be noted that after the solid medicine is put into the barrel 100, the first end of the core rod 200 is extended into the barrel 100. Since the cross-sectional shape of the grinding block 211a is conical, the side edge of the grinding block 211a is directly facing the first grinding surface 112 at this time. In the process of the second grinding surface 211 moving close to the first grinding surface 112, the side edge of the grinding block 211a will first contact the solid medicine, so that the side edge of the grinding block 211a cooperates with the first grinding surface 112. When the second grinding surface 211 continues to move close to the first grinding surface 112, the side edge of the grinding block 211a can cut the solid medicine, thereby breaking the solid medicine, which can better improve the labor-saving effect and make the crushing of the solid medicine more convenient and quick.

[0051] Furthermore, the grinding grooves 112a on the first grinding surface 112 are continuously arranged along the circumferential direction of the first grinding surface 112, so that two adjacent grinding grooves 112a can share the same side edge. When the solid medicine is put into the cylinder 100, the solid medicine will first contact the same side edge shared by the two adjacent grinding grooves 112a when it falls on the first grinding surface 112. Then, when the second grinding surface 211 moves close to the first grinding surface 112, the same side edge shared by the two adjacent grinding grooves 112a will cut the solid medicine, thereby breaking the solid medicine, which can better improve the labor-saving effect and make the crushing of the solid medicine more convenient and quick.

[0052] In some embodiments, a frustum 211b is provided on the second grinding surface 211, and the frustum 211b extends in a direction away from the core rod 200. When the first end of the core rod 200 is inserted into the barrel 100 and the core rod 200 is pushed to move the first grinding surface 112 close to the second grinding surface 211, the frustum 211b on the first grinding surface 112 can be extended into the through hole 111 on the second grinding surface 211, so that during the process of extrusion and grinding of the solid medicine by the first grinding surface 112 and the second grinding surface 211, the frustum 211b can block the through hole 111 to a certain extent, thereby preventing the solid medicine from lumps into the feeder assembly through the through hole 111.

[0053] Furthermore, as the second grinding surface 211 approaches the first grinding surface 112 until it fits with the first grinding surface 112, the cone 211b penetrates deeper and deeper into the via hole 111. During this process, the gap between the cone 211b and the via hole 111 tends to gradually shrink, that is, the sealing effect of the cone 211b on the via hole 111 becomes better and better.

[0054] It should be noted that in the process of extrusion and grinding of the solid medicine by the first grinding surface 112 and the second grinding surface 211, the closer the second grinding surface 211 is to the first grinding surface 112, the smaller the volume of the solid medicine in agglomerates between the first grinding surface 112 and the second grinding surface 211. Correspondingly, as the second grinding surface 211 is closer to the first grinding surface 112, the smaller the gap between the cone 211b and the through hole 111, which means that the blocking of the through hole 111 by the cone 211b changes with the volume of the solid medicine in agglomerates, so that the gap between the cone 211b and the through hole 111 can always be kept smaller than the volume of the solid medicine in agglomerates, thereby better preventing the solid medicine in agglomerates from entering the feeder assembly through the through hole 111, further improving the effect of grinding the solid medicine.

[0055] It can be further known that, in the direction away from the core rod 200, the cross-sectional diameter of the cone 211b tends to gradually decrease, so that in the process of the second grinding surface 211 moving closer to the first grinding surface 112, the diameter of the cone 211b entering the through hole 111 becomes larger and larger, thereby making the gap between the cone 211b and the through hole 111 smaller and smaller, thereby achieving the above-mentioned effect of preventing the solid medicine from agglomerating into the feeder assembly through the through hole 111.

[0056] In some embodiments, the axis of the cone 211b is consistent with the axis of the core rod 200, and the axis of the through hole 111 is consistent with the axis of the cylinder 100, so that when the first end of the core rod 200 is inserted into the cylinder 100 and the cone 211b is inserted into the through hole 111, the core rod 200 can rotate circumferentially in the cylinder 100, thereby realizing the grinding of the solid medicine by the first grinding surface 112 and the second grinding surface 211.

[0057] Furthermore, when the core rod 200 is inserted into the barrel 100, the axis of the core rod 200 is also consistent with the axis of the barrel 100, so that the axis of the cone 211b can be consistent with the axis of the through hole 111, so that the size of the gap between the cone 211b and the through hole 111 can be kept stable, thereby better preventing the solid medicine from entering the feeder assembly through the through hole 111.

[0058] Further, combined with Fig. 9 As shown, the grinding groove 112a arranged on the first grinding surface 112 has a centripetal angle between 0° and 30°, a depth between 0.5mm and 3mm, and a width between 1mm and 6mm; correspondingly, the grinding block 211a arranged on the second grinding surface 211 has a centripetal angle between 0° and 30°, a height between 0.5mm and 3mm, and a width between 1mm and 6mm.

[0059] In some embodiments, a joint 113 is provided on the first extrusion platform 110, and the joint 113 extends in a direction away from the cylinder 100. The cylinder 100 is specifically connected to the feeder assembly through the joint 113. A channel 113a is opened in the joint 113. Furthermore, the axis of the joint 113 is consistent with the axis of the through hole 111, so that the channel 113a in the joint 113 can be connected to the through hole 111.

[0060] Furthermore, an oblique opening 113b is provided at the end of the joint 113 away from the cylinder 100, and the joint 113 can be connected to the feeder assembly through the oblique opening 113b. After the first end of the core rod 200 is inserted into the cylinder 100, the core rod 200 is pushed so that the second grinding surface 211 moves close to the first grinding surface 112. During this process, the truncated cone 211b can pass through the through hole 111 and enter the channel 113a in the joint 113. The truncated cone 211b can be accommodated through the channel 113a, so as to avoid the truncated cone 211b interfering with the relative movement of the first grinding surface 112 and the second grinding surface 211.

[0061] It is particularly important to note that after the solid medicine is ground, when the powder between the first grinding surface 112 and the second grinding surface 211 is pushed into the feeder assembly, the second grinding surface 211 moves close to the first grinding surface 112, so that the powder in the grinding space 300 enters the channel 113a through the through hole 111, and the frustum 211b can further push the powder in the channel 113a, so that the powder can smoothly enter the feeder assembly, which can better avoid the powder from being blocked in the through hole 111 and the channel 113a, so that all the powder formed by the solid medicine through grinding can be pushed into the feeder assembly, which can better avoid the powder from adhering to the through hole 111 or the channel 113a and causing a reduction in the amount of medicine.

[0062] In some embodiments, the middle position of the channel 113a provided in the joint 113 is in the shape of a constriction 113c. When the cone 211b extends into the channel 113a through the through hole 111, as the second grinding surface 211 approaches the first grinding surface 112, the end of the cone 211b away from the core rod 200 can abut against the constriction 113c, so that the cone 211b can block the channel 113a.

[0063] It is understandable that after the truncated cone 211b blocks the channel 113a, there is a small gap between the second grinding surface 211 and the first grinding surface 112, and the gap is used to accommodate the powder formed by the solid medicine. The particle size of the powder in the gap meets the patient's use requirements. To further explain in detail, as the second grinding surface 211 approaches the first grinding surface 112 to grind the solid medicine in blocks, the truncated cone 211b will gradually approach the constriction 113c until the truncated cone 211b blocks the constriction 113c. In this state, the first grinding surface 112 and the second grinding surface 211 grind the solid medicine in blocks into powder. The blocking of the constriction 113c by the truncated cone 211b can prevent the powder from leaking out through the channel 113a. After the powdered solid medicine is pushed into the feeder assembly, the sealing of the constriction 113c by the cone 211b can also prevent the powdered solid medicine from returning to the cylinder 100 through the through hole, so that the powder formed by grinding the solid medicine can all enter the feeder assembly, which can better prevent the powder from returning to the cylinder 100 and causing a reduction in the amount of medicine.

[0064] In some embodiments, a second extrusion platform 210 is provided on the first end of the core rod 200, and a second grinding surface 211 is formed on the end surface of the second extrusion platform 210 away from the core rod 200. An annular mounting groove 212 is provided on the circumferential side wall of the second extrusion platform 210, and a sealing member 212a is fixedly installed in the mounting groove 212. When the first end of the core rod 200 is extended into the barrel 100, the second extrusion platform 210 can form an extrusion between the inner side wall of the barrel 100 and the sealing member 212a, so that the sealing member 212a can block the gap between the second extrusion platform 210 and the inner side wall of the barrel 100, and can better limit the solid medicine between the first grinding surface 112 and the second grinding surface 211, avoid leakage of the medicine, and thus ensure that the amount of medicine will not be lost during grinding.

[0065] Furthermore, when the core rod 200 moves so that the second grinding surface 211 cooperates with the first grinding surface 112 to grind the solid medicine, the seal 212a will clean the powder attached to the inner wall of the cylinder 100 as the core rod 200 moves, so as to prevent the powder from being attached to the inner wall of the cylinder 100. At the same time, when the second grinding surface 211 approaches the first grinding surface 112 to push the powder into the feeder assembly, the seal 212a can better ensure that the powder formed by grinding the solid medicine can all enter the feeder assembly by cleaning the powder attached to the inner wall of the cylinder 100, and can better prevent the powder from returning to the cylinder 100 to reduce the amount of medicine.

[0066] Furthermore, the sealing member 212a may be a rubber strip or a rubber ring, and the sealing member 212a may be fixedly installed in the installation groove 212 by means of bolts, clamping, bonding, etc., and there is no particular limitation on this.

[0067] In some embodiments, the diameter of the core rod 200 is smaller than the inner diameter of the cylinder 100, and at least one support plate 220 is provided on the circumferential side wall of the core rod 200. When the core rod 200 is extended into the cylinder 100, the support plate 220 can abut against the inner wall of the cylinder 100, thereby maintaining the stability of the core rod 200, so that when the user pushes, pulls or rotates the core rod 200, the core rod 200 will not shake in the radial direction.

[0068] Furthermore, a handle 230 is provided on the second end of the core rod 200 and protrudes from the circumferential side wall of the core rod 200. The setting of the handle 230 can increase the contact area of ​​the second end of the core rod 200, so that the user can press the second end of the core rod 200 to make the second grinding surface 211 close to the first grinding surface 112. Of course, the setting of the handle 230 can also facilitate the user to push, pull or rotate the core rod 200, thereby achieving an effect of easy use.

[0069] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
