DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 7 As shown, this embodiment discloses an infant medication device, including a medicine feeding nozzle 1, which is made of food-grade silicone. The medicine feeding nozzle 1 includes a liquid outlet 12 and a first annular groove 13. The lower part of the medicine feeding nozzle 1 is connected to a shell 2, and the shell 2 includes an annular rib 26. The annular rib 26 is inserted into the first annular groove 13 for limiting position. Through the cooperation of the annular rib 26 and the first annular groove 13, a detachable design of the medicine feeding nozzle 1 and the shell 2 can be achieved.

[0037] An annular sleeve 3 is provided inside the shell 2, a second annular groove 21 is provided inside the shell 2, the annular sleeve 3 is embedded in the second annular groove 21, the annular sleeve 3 is a silicone member, the annular sleeve 3 includes a clamping cavity 31, the upper and lower ends of the clamping cavity 31 are openings, the upper end of the clamping cavity 31 is connected to the liquid outlet 12, a capsule 8 is provided in the clamping cavity 31, the side wall of the capsule 8 and the clamping cavity 31 can be sealed, the upper part of the shell 2 is connected to a slotted member 4, the slotted member 4 is located in the medicine feeding nozzle 1, the slotted member 4 includes a puncture piece 42, and the puncture piece 42 can abut and pierce into the capsule 8;

[0038] When in use, the capsule 8 is placed in the clamping cavity 31. When the baby sucks on the medicine feeding nozzle 1, suction will be generated inside the medicine feeding nozzle 1. Since the capsule 8 is sealed with the side wall of the annular sleeve 3, the suction generated will push the capsule 8 to move, and the puncture piece 42 can penetrate into the capsule 8, so that the medicine liquid in the capsule 8 flows out, and the outflowing medicine liquid enters the baby's mouth through the liquid outlet 12, thereby realizing automatic drug administration for the baby, which is easy to operate. Moreover, when the drug is automatically administered, the drug is administered through the baby's autonomous sucking. The drug administration speed is related to the baby's own sucking force, and no manual adjustment is required, which effectively reduces the risk of choking of the baby. Moreover, through the baby's autonomous sucking, the medicine liquid naturally enters the baby's mouth, which can reduce the discomfort of the baby during drug administration.

[0039] The lower part of the shell 2 is covered with a thin sheet 6, and the thin sheet 6 can seal the lower end of the clamping cavity 31. Specifically, the lower part of the shell 2 is provided with a drug inlet 25, and the drug inlet 25 is directly opposite to the clamping cavity 31. The thin sheet 6 is a silicone sheet. A cover body 5 is installed at the lower part of the thin sheet 6. The cover body 5 is connected to the shell 2 by threads. The cover body 5 includes an avoidance hole 51, and the avoidance hole 51 is located below the drug inlet 25. The thin sheet 6 includes a convex head 61, and the convex head 61 can penetrate the drug inlet 25 and be inserted into the clamping cavity 31. The convex head 61 is provided with a folded part 62 on the side, and the folded part 62 can be deformed to make the convex head 61 movable. Through the threaded connection between the cover body 5 and the shell 2, not only can the position of the thin sheet 6 be fixed, but also the disassembly and assembly of the shell 2, the cover body 5 and the thin sheet 6 can be realized;

[0040] When in use, the capsule 8 is installed in the clamping cavity 31 from the medicine inlet 25, and then the cover body 5 provided with the thin sheet 6 is threadedly connected to the shell body 2, and the medicine inlet 25 is sealed by the thin sheet 6. When the capsule 8 is punctured, the liquid in the capsule 8 flows out, and the capsule 8 will be deformed and deflated. At this time, the capsule 8 and the inner wall of the clamping cavity 31 are not sealed, but because the thin sheet 6 is a silicone sheet and the material is very soft, after the capsule 8 is punctured, the convex head 61 of the thin sheet 6 will move toward the capsule 8 due to the sucking force of the baby, and the folded part 62 can be extended, and the capsule 8 can be pushed to continue to move through the convex head 61, and the puncture sheet 42 can penetrate deeper, which is convenient for the medicine in the capsule 8 to flow out, and the clamping cavity 31 is always in a closed state, which can effectively prevent the outside air from being sucked into the baby's body, reduce the baby's intestinal flatulence, and improve the baby's drug administration effect.

[0041] A sliding sleeve 7 is provided below the cover body 5, and a push rod 71 is provided inside the sliding sleeve 7. The push rod 71 passes through the avoidance hole 51 and the end thereof is inserted into the area surrounded by the pleated portion 62. The sliding sleeve 7 can move up and down so that the upper part of the push rod 71 abuts against the lower part of the protrusion 61 and pushes the capsule 8 to move toward the puncture sheet 42. Specifically, the sliding sleeve 7 is connected to the push rod 71 through a connecting rib 72. A plurality of buckles 73 are provided on the upper part of the sliding sleeve 7. The buckles 73 are sleeved on the outer side of the cover body 5. A convex block 74 is provided on the inner side of the buckle 73. The convex block 74 is located above the cover body 5. The lower part of the convex block 74 can abut against or be separated from the upper part of the cover body 5. If the sucking force of the baby is insufficient or the epidermis of the capsule 8 is thick, the sliding sleeve 7 can be installed on the cover body 5 to realize manual drug administration.

[0042] Specifically, after the cover body 5 and the shell body 2 are assembled, the sliding sleeve 7 is sleeved on the outside of the cover body 5. During the connection process, the buckle 73 is deformed, and its protrusion 74 abuts against the side of the cover body 5, pushing the sliding sleeve 7, and the protrusion 74 can pass over the cover body 5. After the protrusion 74 passes over the cover body 5, the buckle 73 recovers its deformation, and the lower part of the protrusion 74 can abut against the upper part of the cover body 5, thereby realizing a detachable connection between the cover body 5 and the sliding sleeve 7. When manually administering the drug, it is only necessary to push the sliding sleeve 7, and the push rod 71 abuts against the lower part of the protrusion 61 and pushes the protrusion 61, and the capsule 8 is pushed to move through the protrusion 61 to ensure that the puncture sheet 42 can puncture the capsule 8, thereby realizing manual administration and convenient operation.

[0043] like Figure 2 As shown, the inner wall of the clamping cavity 31 is provided with a plurality of annular sealing ribs 33, and the capsule 8 is sealed with the sealing ribs 33. By providing the sealing ribs 33, not only the sealing effect with the capsule 8 can be improved, but also the contact area with the capsule 8 can be reduced, thereby reducing the movement resistance of the capsule 8.

[0044] like Figure 1 and Figure 3 As shown, a conical groove 11 is provided inside the medicine feeding nozzle 1, and the conical groove 11 is located above the clamping cavity 31 and is connected to the liquid outlet 12. The grooved member 4 is located in the conical groove 11, and the grooved member 4 includes a connecting piece 41. The puncture piece 42 is located at the lower part of the connecting piece 41. Deformation pieces 43 are provided on both sides of the connecting piece 41. The outer side of the deformation piece 43 is close to the surface of the conical groove 11. An annular platform 32 is provided on the upper part of the annular sleeve 3, and the annular platform 32 exceeds the upper part of the shell 2. The annular platform 32 abuts against the inner wall of the conical groove 11 so that the deformation piece 43 is embedded in the annular platform 32. Through the cooperation between the conical groove 11 and the grooved member 4 and the cooperation between the annular platform 32 and the grooved member 4, not only the fixing effect of the grooved member 4 can be improved, but also the entry of the liquid medicine into the gap between the outer side of the annular platform 32 and the deformation piece 43 during medication can be greatly reduced.

[0045] like Figure 3As shown, the upper part of the shell 2 is provided with a mounting groove 22 corresponding to the deformation piece 43, the lower end of the deformation piece 43 is inserted into the mounting groove 22 for limiting, the mounting groove 22 is provided with a convex rib 23 on the side facing the center of the shell 2, the mounting groove 22 is located in the area below the convex rib 23 to form a limiting groove 24, the lower part of the deformation piece 43 is provided with a hook 44, the hook 44 is inserted into the limiting groove 24, the convex rib 23 is located between the deformation piece 43 and the hook 44, through the cooperation between the hook 44 and the mounting groove 22, not only the slotted part 4 can be fixed, but also the slotted part 4 is convenient for disassembly and assembly;

[0046] In the present invention, the medicine feeding nozzle 1, the shell 2, the annular sleeve 3, the slotted member 4, the cover 5, the thin sheet 6 and the sliding sleeve 7 can all be disassembled, thereby facilitating the cleaning and disinfection of the various components.

[0047] like Figures 4 to 6 As shown, the slotted member 4 is an elastic metal member, the connecting end of the connecting piece 41 and the deformable piece 43 is a flexible portion 45, the deformable piece 43 can swing along the flexible portion 45, the length of the puncture piece 42 is less than the length of the deformable piece 43, when the slotted member 4 is connected to the housing 2, the angle between the two deformable pieces 43 is an obtuse angle, when the slotted member 4 is separated from the housing 2, the angle between the two deformable pieces 43 is an acute angle and the lower end of the deformable piece 43 is lower than the lower end of the puncture piece 42;

[0048] like Figure 6 The slotted member 4 shown is in an initial state, in which the two deformable sheets 43 are close to the puncture sheet 42, protecting the puncture sheet 42. In this state, the risk of the puncture sheet 42 piercing the human body when taking the slotted member 4 can be greatly reduced, and the safety is good. When the slotted member 4 needs to be assembled with the shell 2, the hook portion 44 of the deformable sheet 43 on one side can be embedded in the limiting groove 24, and the deformable sheet 43 on the other side can be pulled so that the hook portion 44 of the deformable sheet 43 on the other side is embedded in the limiting groove 24 on the other side, thereby fixing the slotted member 4.
