It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0027] Figure 1 The schematic diagram of the structure of the device is shown, and the specific structure and principle of the device are as follows:

[0028] like Figure 1 and Figure 2 As shown, a therapeutic drug feeding device is characterized in that it includes

[0029] A medicine feeding cylinder body 5, one end of which is provided with an external thread; a push rod 2, which is inserted into the interior of the medicine feeding cylinder body 5 and has a grinding head 10 on its head; a rubber piston 8, which is sleeved on the push rod 2 above the grinding head 10 and is interference connected with the inner surface of the medicine feeding cylinder body 5; a grinding base 14, a grinding groove 9 is provided inside the grinding base 14, and an internal thread is provided at the upper edge of the inner wall of the grinding groove 9 to be threadedly connected with the medicine feeding cylinder body 5, and the grinding base 14 is also provided with a liquid outlet.

[0030] Preferably, in this embodiment, the head of the push rod 2 is further provided with a guide groove 7, and a blade 6 is provided at the bottom of the guide groove 7 to cooperate with the positioning groove 12 on the raised top of the grinding base 14 to avoid the blade 6 from shifting when cutting the tablets, thereby improving the cutting accuracy of the blade 6 on the tablets.

[0031] Preferably, in this embodiment, the grinding base 14 is further provided with a protrusion cooperating with the guide groove 7, and a positioning groove 12 cooperating with the blade 6 is provided on the top of the protrusion. In addition to cooperating with the guide groove, the protrusion also provides an installation position for the nozzle and the positioning groove.

[0032] Preferably, in this embodiment, the surface of the grinding head 10 and the grinding base 14 are provided with grinding teeth 11 that cooperate with each other. The tablets are ground by the relative movement between the grinding teeth 11 and the tablets. The grinding teeth that cooperate with each other can fully and evenly grind the tablets into drug powder of ideal particle size.

[0033] Preferably, in this embodiment, the cross-sections of the bottoms of the grinding head 10 and the grinding groove 9 are both conical, so that during grinding, the drug powder is enriched around the grinding base, which reduces the escape of the drug powder from the nozzle.

[0034] Preferably, in this embodiment, the liquid outlet is provided with a nozzle 13 inside the grinding groove 9 , and the water outlet direction of the nozzle 13 is parallel to the laying direction of the grinding teeth 11 , so that the nozzle 13 has a better flushing effect on the grinding teeth 11 .

[0035] Preferably, in this embodiment, the number m of the nozzles 13 is ≥ 3 and they are evenly distributed in the circumferential direction. The even distribution of the nozzles 13 in the circumferential direction can make the flushing effect of the nozzles on the grinding teeth 11 more uniform.

[0036] Preferably, in this embodiment, the rear end of the nozzle 13 body is connected to a soft rubber straw 15, and the soft rubber straw 15 extends through the liquid outlet to the outside of the grinding base 14. The soft rubber straw 15 is covered with a dust cover 16. The soft rubber straw 15 can avoid damage to the oral cavity of the patient, especially the patient who does not cooperate with taking the medicine. The dust cover 16 can prevent the soft rubber straw 15 from being contaminated by opening and then contaminating the medicine when it is stored.

[0037] Preferably, the push rod 2 is provided with a pull ring 1 at the tail end, and the medicine feeding cylinder body 5 is provided with a buckle ring 3 at the tail end. There are two buckle rings 3 and they are symmetrically installed. The installation of the pull ring 1 is conducive to the push, pull and rotation operations of the push rod, and the installation of the buckle ring 3 is conducive to the control operation of the medicine feeding cylinder body 5.

[0038] Preferably, in this embodiment, the outer surface of the medicine feeding cylinder 5 is provided with a scale mark 4, which is convenient for controlling the amount of clean water added during dissolution and for quantitative feeding of medicine, thereby facilitating the medicine feeding operation and improving the ease of use.

[0039] Figure 2 An enlarged view of the local structure of the device is shown.

[0040] When the utility model is in use, the tablet is directly placed in the positioning groove 9 on the protrusion of the grinding base 14, and the position of the tablet can be adjusted to control the cutting amount. The feeding cylinder body 5 and the grinding base 14 are connected by the external thread of the feeding cylinder body 5 and the internal thread of the grinding base 14. The push rod 2 is pushed by the pull ring 1 to drive the rubber piston 8 to move downward along the inner wall of the feeding cylinder body 5. The feeding cylinder body 5 is restricted to follow the push rod 2 by buckling the buckle ring 3. The guide groove 7 at the tail of the push rod 2 is inserted into the positioning groove 9 on the protrusion of the grinding base 14. The push rod 2 continues to move downward, and the blade 6 in the guide groove 7 contacts the tablet to complete the tablet segmentation. The push rod 2 is pulled up a distance by the pull ring 1. If some tablets need to be taken out, the feeding cylinder body 5 and the grinding base can be unscrewed. 14. If it is not necessary to take out some tablets, the feeding cylinder body 5 can be simply shaken to facilitate all the tablets to fall into the grinding groove 9 inside the grinding base 14. Push the push rod 2 until it is difficult, and then rotate the push rod 2 through the pull ring 1 to drive the grinding head 10 at the head of the push rod 2. By buckling the buckle ring 3, the movement of the feeding cylinder body 5 is limited to be kept in a relatively static state. The rotation direction of the push rod 2 is preferably clockwise and consistent with the tightening direction of the feeding cylinder body 5 and the grinding base 14, so as to avoid the rotation of the push rod 2 during the grinding process, causing the feeding cylinder body 5 and the grinding base 14 to loosen or fall off. The grinding teeth on the lower surface of the grinding head 10 and the grinding base 14 are used to grind the tablets that have been cut into small pieces in the grinding groove 9. During the grinding process, the guide groove 7 simultaneously blocks the protrusion from the outside world. The nozzle 13 connected to the air can prevent fine drug powder from escaping from the grinding base 14 through the nozzle 13 and the soft rubber straw 15 during the grinding process, causing drug waste. After the tablets are ground into particles of appropriate size, the dust cover 16 is removed, the soft rubber straw 15 is placed in clean water, and the push rod 2 is pulled upward to drive the rubber piston 8 to move upward along the inner wall of the feeding cylinder body 5. Negative pressure is generated inside the feeding cylinder body 5, and the clean water is sucked into the grinding groove 9 through the nozzle 13 along the soft rubber straw 15. In the process from the suction of the clean water to the final ejection from the nozzle 13, the diameter of the pipe passing through is continuously reduced, and the pressure of the clean water is gradually increased. The pressure is the largest when it is ejected from the nozzle 13. The water outlet direction of the nozzle 13 is parallel to the direction of the grinding teeth 11, which can play a role in the residual drug powder on the grinding teeth 11. The flushing effect is beneficial to dissolution. After judging the appropriate amount of clean water by the scale mark 4 on the body of the medicine feeding cylinder, the water absorption is stopped, and the medicine powder is dissolved in the grinding groove 9 and the medicine feeding cylinder 5. The push rod 2 can be rotated for simple stirring to facilitate dissolution. After the dissolution is completed, the push rod 2 is pushed to push the dissolved medicine liquid into the patient's mouth through the nozzle 13 through the soft rubber straw 15. The feeding amount can be controlled by the scale mark on the surface of the medicine feeding cylinder 5. After the feeding is completed, the push rod 2 can be operated to move up and down or rotate in the medicine feeding cylinder 5 to absorb clean water to rinse the medicine feeding cylinder 5 and the grinding base 14, or the medicine feeding cylinder 5 and the grinding base can be unscrewed for rinsing and drying respectively. After that, the dust cover 16 is put on the soft rubber straw 15 for easy storage for next use.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
