[0021] In order to make the purpose, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope protected by the present invention.

[0022] Specific embodiments of the present invention provide a medicine feeder, as shown in the attached Figure 1 and the attached Figure 2 It mainly includes a grinding part 1, a syringe part 2 and a piston part 3. The grinding part 1 is used for grinding medicine. The grinding part 1 is connected to the syringe part 2 through a one-way valve 4. The medicine powder ground by the grinding part 1 enters the inside of the syringe part 2 through the one-way valve 4 for mixing. The piston part 3 is slidably arranged in the syringe part 2. The piston part 3 cooperates with the syringe part 2 to realize the water pumping and medicine feeding functions of the syringe. When the piston part 3 is pulled out, water can be pumped into the syringe part 2, and then the mixing of medicine powder and water can be carried out. When the piston part 3 is pushed in, the medicine feeding function can be realized. Before pushing the medicine, the syringe part 2 needs to be connected to the gastric tube or intestinal tube. Using this kind of medicine feeder in this application can reduce the labor of medical staff.

[0023] Specifically, the grinding part 1 in this application can be an electric grinder. Put the medicine into the electric grinder and automatically grind it through the electric grinder. This grinding method can grind finer and avoid the risk of large particles blocking the gastric tube or intestinal tube.

[0024] In a specific embodiment of this application, the piston part 3 can include a cylinder body 5 and a piston 6. The piston 6 is arranged at one end of the cylinder body 5 and is located inside the syringe part 2. The piston 6 is closely attached to the inner wall of the syringe part 2. The grinding part 1 is arranged in the cylinder body 5 far away from the piston 6. A one-way valve 4 is arranged in the middle of the piston 6. The one-way valve 4 is communicated with the cylinder body 5. The medicine outlet of the grinding part 1 is communicated with the cylinder body 5. This way can ensure that the medicine powder ground by the grinding part 1 enters the cylinder body 5 and then enters the syringe part 2 through the one-way valve 4.

[0025] The way that the grinding part 1 is arranged in the cylinder body 5 enables the grinding part 1 to be taken out from the inside of the cylinder body 5.

[0026] It should be noted that the material of the cylinder body 5 can be a transparent material, and the situation of the medicine powder inside can be observed through this cylinder body 5, which is convenient for the operation of medical staff.

[0027] In some embodiments, the piston part 3 further includes an end cap 7 and an airbag 8. The end cap 7 is covered on the end of the cylinder body 5 far away from the piston 6. The airbag 8 is arranged on the cylinder body 5 or the end cap 7. The airbag 8 is communicated with the grinding part 1. The end cap 7 is opened when putting in the medicine cake and closed after putting in the medicine cake. The airbag 8 can, after grinding is completed and water is pumped into the syringe part 2, blow the medicine powder into the water in the syringe part 2 by pressing the airbag 8. It should be noted that when blowing in the medicine powder, part of the water will be discharged from the outlet at the bottom of the syringe part 2. The process of blowing in the medicine powder is completed in a short time and will not cause the loss of the liquid medicine.

[0028] In some embodiments, a filter screen 9 is provided at the discharge port of the grinding part 1 to filter large-particle drugs through the filter screen 9, so as to further avoid the risk of large particles blocking the gastric tube or intestinal tube.

[0029] In some embodiments, a driving mechanism 10 is further included. The driving mechanism 10 is arranged on the syringe part 2, and the driving mechanism 10 is in transmission connection with the piston part 3. The driving mechanism 10 is used to drive the movement of the piston part 3, so as to further reduce the workload of medical staff.

[0030] In some embodiments, the driving mechanism includes a driving motor, a gear and a rack. The driving motor is arranged on the syringe part 2, the gear is arranged at the driving end of the driving motor, the rack is arranged on the piston part 3, and the rack is arranged along the length direction of the piston part 3. In this way, the rotation of the driving motor can drive the gear to rotate, the rotation of the gear drives the rack that is expected to be engaged to move, and then drives the piston part 3 to move. For this purpose, a control panel 11 needs to be arranged outside the syringe part 2, and control buttons can be arranged on the control panel 11 to control the start, stop, forward and reverse rotation of the driving motor through the control buttons.

[0031] In some embodiments, the syringe part 2 includes a syringe body 12 and a limiting end cover 13. One end of the syringe body 12 is the needle end, and the limiting end cover 13 is arranged at the other end. The limiting end cover 13 and the syringe body 12 can be connected by a threaded connection method. In this way, the limiting end cover 13 can be removed from the syringe body 12. The middle part of the limiting end cover 13 has a through hole, and the piston part 3 is slidably arranged in the through hole. The position of the piston part 3 can be limited through this through hole, so as to avoid the piston part 3 from shifting. It should be noted that when the gear-rack transmission method is adopted in this application, a notch can be arranged on the inner wall of the through hole for the rack to move.

[0032] In some embodiments, the driving motor is arranged in the syringe body 12 close to the limiting end cover 13. Specifically, the number of the driving mechanisms can be multiple and they are evenly arranged on the circumferential side of the syringe body 12.
