In the present invention, the bottom end of the guide drive shaft 17 passes through the annular guide support 14 and then extends to the top of the medicine outlet seal plug 8. The annular guide support 14 includes an inner ring body 37 and an outer ring body 35 coaxially connected by support ribs 36. The inner ring body 37 is slidably connected to the guide drive shaft 17. The medicine outlet seal plug 8 is in the space formed by the bottom end of the injection cavity 4 and the reduced diameter structure 34. A medicine outlet cavity port 13 for liquid to flow into the medicine outlet flow channel 10 is opened on one side of the bottom of the space. A medicine outlet spring 9 is arranged between the bottom of the medicine outlet seal plug 8 and the bottom surface of the injection cavity 4.

The drug outlet channel 10 is composed of the outer wall of the outer cylinder 3 and the drug outlet guide seat 12 at the bottom of the inner cylinder 21, and the cross section of the drug outlet guide seat 12 is triangular. A downwardly protruding and pluggable drug outlet interface 11 is provided at the confluence of the drug outlet channel 10, and the drug outlet interface 11 is detachably connected to a drug feeding aid.

The medicine feeding aid includes a disassembly connection end 38 plugged into the medicine outlet interface 11, and the disassembly connection end 38 is plugged into and tightly fits on the medicine outlet interface 11 in a self-deformed manner. The disassembly connection end 38 is integrated with the flat soft body 42, and both are made of medical silicone material. The interior of the flat soft body 42 is provided with a soft body guide channel 40 distributed along its shape, and the soft body guide channel 40 is connected to the soft body liquid outlet 41, and the outlet of the soft body liquid outlet 41 is located on the outer wall of the flat soft body 42, and the outlet of the soft body liquid outlet 41 is smaller than the inlet diameter. The shape of the flat soft body 42 described in the present invention is an eight-shaped structure, and a soft body guide end 39 is provided at the inlet of the soft body guide channel 40, and the soft body guide end 39 is used to divert the liquid sent into the medicine outlet interface 11 to the soft body guide grooves 40 on both sides. The cross-section of the soft body guide end 39 described in the present invention is a triangle.

In the present invention, the medicine feeding aid can also be configured as a pacifier structure so as to be better configured for infants and young children.

Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

When the present invention is used, distilled water or saline is injected into the inner cylinder cavity 22, and then the end plug body 26 including the sealing ring 28 and the auxiliary glass plug 23 are inserted into the inner cylinder cavity 22 by pressing the handle 1 and the guide rod 24. The distilled water or saline enters the liquid guide cavity 30 through the liquid guide inlet 29 under the action of the end plug body 26, but in the initial state, a large amount of distilled water or saline is not allowed to contact the driving impeller 18 through the liquid outlet sleeve 19.

At the same time, the liquid medicine to be fed is injected into the injection port 7 through the injection rubber plug 6 by a syringe in advance, and then injected into the injection cavity 4 below the glass plug body 16 through the injection port 7. The dry powder medicine can be mixed in the syringe before injection, or after removing the injection rubber plug 6, the powder medicine is placed in the injection cavity 4 and an appropriate amount of liquid is injected to pre-weld or mix, and then the injection rubber plug 6 is tightly connected. After the injection rubber plug 6 is tightly connected, it can be fitted with the injection port 7.

In the present invention, after the injection is completed, the thumb continues to press the pressing handle 1, and the other fingers hold the gripping rubber sleeve 2. Under the continued pressure of the pressing handle 1, the distilled water or physiological saline continues to enter the liquid guiding cavity 30 through the liquid guiding inlet 29, and continues to enter the liquid distributing interlayer 32 formed by the hollow interlayer of the liquid outlet sleeve 19 through the liquid distributing inlet 31 on the liquid outlet sleeve 19, and is fed in through the liquid distributing outlet 33 in the tangential direction. The tangential direction is the best, but other directions are also acceptable, as long as the driving impeller 18 is driven to rotate.

The distilled water or saline solution delivered in the tangential direction impacts the driving impeller 18 under the action of pressure, and the driving impeller 18 drives the guide driving shaft 17 to rotate, and the guide driving shaft 17 drives the glass stopper 16 and the spiral stirring part 15 arranged thereon to rotate. In addition, since a small gap is left between the glass stopper 16 and the injection cavity 4, the liquid can play a lubricating role but will not enter into the bottom of the glass stopper 16 in large quantities. The distilled water or saline solution accumulated in the injection cavity 4 above the glass stopper 16 will force the glass stopper 16 to move downward along the inner wall of the injection cavity 4.

The spiral stirring part 15 can stir the liquid medicine in the injection cavity 4 below the glass plug body 16, and in the process of the glass plug body 16 moving downward, the end of the guide drive shaft 17 is used to apply pressure to the medicine outlet seal plug 8. Under the combined action of the liquid medicine, the glass plug body 16, and the saline or distilled water injected above the glass plug body 16, the medicine outlet seal plug 8 can overcome the force of the medicine outlet spring 9 below, and the sealing structure of the originally sealed shrinking structure 34 is opened. It should be noted that the length of the glass plug body 16 is sufficient to cover the outlet length of the injection port 7, and in the process of the guide drive shaft 17 moving downward, a limiting structure that cooperates with the annular guide support 14 is provided on the guide drive shaft 17. The limiting structure is located below the spiral stirring part 15, and its diameter is the same as that of the inner ring body 37 on the annular guide support 14.

The medicine liquid stirred by the spiral stirring part 15 enters the corresponding medicine outlet flow channel 10 through the opened medicine outlet seal 8 and the reducing structure 34, and the medicine outlet flow channel 10 gradually converges to the medicine outlet interface 11 and enters the medicine feeding aid connected to it in a detachable manner such as plug-in.

In order to facilitate the feeding of medicines to the elderly and infants and to avoid the drug feeding reaction caused by the original hose, the drug feeding aid is set to an eight-shaped structure, and includes a disassembly connection end 38 and a flat soft body 42 integrally formed with the disassembly connection end 38. The flat soft body 42 can be set to different sizes according to different age groups. A soft body guide channel 40 adapted to its shape is arranged inside the flat soft body 42, and the soft body guide channel 40 is connected to a plurality of soft body liquid outlets 41. The inlet diameter of the soft body liquid outlet 41 is larger than the outlet diameter to increase the outflow speed of the liquid medicine. In order to achieve the uniformity of the liquid medicine diversion to both ends, a soft body guide end 39 can be arranged at the disassembly connection end 38.

After the medicine feeding is finished, the internal structure can be cleaned by disassembling the structure including the pressing handle 1, the auxiliary glass plug 23, the end plug body 26, and the injection rubber plug 6. The medicine feeding auxiliary device can also be cleaned by injecting physiological saline. At the same time, the liquid outlet sleeve 19 described in the present invention can be disassembled and cleaned through a detachable top plug body 20. The top plug body 20 is connected to the top of the injection cavity 4 in an interference fit manner and is located between the outer cylinder 3 and the inner cylinder 21.

Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
