The embodiments of this utility model will now be described based on its overall structure.

[0039] like Figures 1-4 As shown, this utility model discloses a medication feeder for elderly care, including a syringe 1, a piston mechanism 2, a drive mechanism 3, and a storage bottle 4. The syringe 1 has an inlet 11 at one end and an outlet 12 at the other end, with a groove 13 on its wall. The piston mechanism 2 includes an infusion channel 21 and a one-way valve 22. The infusion channel 21 extends through both ends of the piston mechanism 2, and the one-way valve 22 is located within the infusion channel 21. The peripheries of both ends of the piston mechanism 2 are slidably connected to the inner wall of the syringe 1. The drive mechanism 3 is located at the slot 13 and is used to drive the piston mechanism 2 to move horizontally within the syringe 1. When the piston mechanism 2 moves towards the inlet 11, the liquid medicine at the rear end of the piston mechanism 2 flows into the front end of the piston mechanism 2 through the infusion channel 21 and the one-way valve 22. When the piston mechanism 2 moves towards the outlet 12, the infusion channel 21 is closed by the one-way valve 22, and the liquid medicine at the front end of the piston mechanism 2 is squeezed out of the outlet 12. The bottle opening 41 of the storage bottle 4 is detachably connected to the inlet 11. In use, the bottle opening 41 of the storage bottle 4 is kept tilted downward so that the liquid medicine in the storage bottle 4 flows into the inlet 11. Then, by controlling the drive mechanism 3 with one hand, the piston mechanism 2 is driven to move horizontally back and forth within the syringe 1, which can squeeze the liquid medicine in the storage bottle 4 out of the outlet 12. This avoids repeated extraction and feeding, facilitates one-handed operation, and helps improve the efficiency of medication administration.

[0040] Specifically, the piston mechanism 2 in the embodiment further comprises a front piston 23, a support 24 and a rear piston 25 connected in sequence, the infusion channel 21 penetrates through the front piston 23, the support 24 and the rear piston 25, and the one-way valve 22 is arranged close to the front piston 23. Preferably, the periphery of the front piston 23 and the rear piston 25 is provided with a sealing ring, and is in sliding connection with the inner wall of the syringe 1, which can play a role of sliding sealing.

[0041] With reference to the foregoing Figure 5 , the one-way valve 22 in the embodiment is arranged as a rubber pipe with one end being a flat mouth. Normally, the flat mouth is closed by two rubber sheets abutting against each other. When the rear piston 25 moves towards the liquid inlet 11, the rubber sheets of the one-way valve 22 are subjected to pressure from the inside of the rubber pipe, the two rubber sheets move away from each other, the flat mouth is open, and the liquid outside the rear piston 25 flows into the front end of the front piston 23 through the infusion channel 21. When the front piston 23 moves towards the liquid outlet 12, the rubber sheets of the one-way valve 22 are subjected to pressure from the outside, the two rubber sheets tightly adhere to each other, the flat mouth is tightly closed, the infusion channel is closed, and the liquid in the front end of the front piston 23 is squeezed out of the liquid outlet 12.

[0042] With reference to the foregoing Figure 2 and Figure 6 , the driving mechanism 3 in the embodiment comprises a housing 31, a sawtooth pressure rod 32, a variable speed gear set 33 and a straight rack 34. The housing 31 is mounted outside the slot 13. One end of the sawtooth pressure rod 32 is in rotational connection with the housing 31, and the other end is in meshing connection with the variable speed gear set 33. The variable speed gear set 33 is arranged in the housing 31 and is in meshing connection with the straight rack 34. The straight rack 34 is mounted on the piston mechanism 2 in the slot 13. Specifically, the straight rack 34 is fixedly mounted on the support 24 in the slot 13. The piston mechanism 2 is arranged close to the liquid inlet 11. The slot 13 is arranged at the middle and rear section of the barrel wall of the syringe 1, so that the front piston 23 and the rear piston 25 cannot reach the slot 13 when moving. It is worth noting that the application of the variable speed gear set 33 can improve the driving efficiency of the driving mechanism 3 on the piston mechanism 2. By controlling the amplitude of the finger pressing the sawtooth pressure rod 32, the injection amount and injection speed of the liquid can be adjusted as needed, so as to adapt to different types of patients.

[0045] It is worth noting that the sawtooth pressure rod 32 further comprises a limiting protrusion 324, the upper part of the arc-shaped rack 323 is engaged with the gear set 33, and the limiting protrusion 324 is arranged at the bottom of the arc-shaped rack 323. When the lower end of the pressure rod 321 moves to the initial position, the limiting protrusion 324 can abut against the inner edge of the shell 31, preventing the arc-shaped rack 323 from continuing to swing towards the outside of the shell 31, and avoiding the arc-shaped rack 323 from disengaging from the gear set 33.

[0046] Further, the gear set 33 in the embodiment comprises a driving wheel 331, a driven wheel 332 and a transmission wheel 333, the driving wheel 331 and the driven wheel 332 rotate in opposite directions, and the driving wheel 331 and the transmission wheel 333 rotate in the same direction. Preferably, the driving wheel 331 and the driven wheel 332 are both arranged as double gear wheels, the size of the driven wheel 332 is larger than that of the driving wheel 331, and the size of the driving wheel 331 is larger than that of the transmission wheel 333. It can be understood that the double gear wheel comprises two gears connected coaxially, the small gear of the driving wheel 331 is engaged with the upper part of the arc-shaped rack 323, the large gear of the driving wheel 331 is engaged with the small gear of the driven wheel 332, the large gear of the driven wheel 332 is engaged with the transmission wheel 333, and the transmission wheel 333 is engaged with the straight rack 34.

[0047] Continuing to refer to Figure 8 The liquid storage bottle 4 in the embodiment comprises a gas return valve 42 arranged at the bottom of the liquid storage bottle 4, which can balance the pressure inside and outside the liquid storage bottle 4; and the bottle mouth 41 of the liquid storage bottle 4 is detachably connected with the liquid inlet 11, preferably by screw connection, which is convenient for disassembly and cleaning, and the liquid storage bottle can support one-time completion of a large amount of liquid addition.

[0048] Continuing to refer to Figure 9Also comprises a nipple 5, which is internally provided with a cavity, the rear end is provided with an opening 51, the front end is provided with a through hole 52, the opening 51 is matched with the liquid outlet 11. Specifically, the nipple 5 is made of silica gel material, which will not cause damage to the patient's oral cavity during use, and the opening 51 and the liquid outlet 11 are detachably connected, which facilitates the disassembly, cleaning and replacement of the nipple 5. In addition, the rear end of the nipple 5 is provided with a baffle 53, and the four through holes 52 are respectively arranged on the front end of the nipple 5, which can avoid the choking caused by the direct injection of the liquid medicine into the throat.
