Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent drug delivery device for clinical nursing. Background Technology

[0002] In clinical nursing, administering medication to patients who are unable to take it independently (such as infants, young children, and those with impaired consciousness) is a crucial basic nursing care procedure. Currently, the common practice is to manually administer the medication using a hand-held spoon and a regular bowl. While this method is simple and low-cost, the coordination between the spoon and the bowl presents significant challenges, severely impacting the efficiency of medication administration and the quality of care.

[0003] First, the medicine is inconvenient to scoop and prone to spillage. Clinical medicine dosages are precise, and the open, curved bottom design of ordinary bowls makes it difficult to scoop accurately with a spoon in one go. Repeated use can cause the spoon to collide with the bowl wall, resulting in spillage, waste, and dosage errors. Viscous or suspended medicines can also adhere to the bowl wall, exacerbating the risk of errors. Secondly, the nursing intensity and operational difficulty are high. Nurses need to take care of multiple patients. Traditional medication administration requires pouring the medicine into a bowl first and then feeding it spoonful by spoonful, which is time-consuming. Holding the bowl and spoon for a long time can easily cause arm fatigue, especially when administering medication to bedridden patients. The separate design further increases the requirements for operational coordination.

[0004] In summary, the traditional method of using a medicine feeding spoon with a bowl has many problems and cannot meet the needs of modern clinical nursing. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] according to Figs. 1-3 As shown, an intelligent medication feeding device for clinical nursing includes a medication chamber 1. The internal thread at the top of the medication chamber 1 is screwed into the external thread at the bottom of a power box 2. This configuration allows for the separation of the medication chamber 1 and the power box 2, enabling medication feeding and cleaning. A peristaltic pump 3 is installed inside the power box 2. The inlet end of the peristaltic pump 3 is connected to the medication chamber 1, and the outlet end of the peristaltic pump 3 is connected to the medication nozzle 8. A power assembly is installed on one side of the peristaltic pump 3. The power assembly includes a stirring shaft 13, a worm gear 18, a worm 12, a threaded rod 10, a push rod 15, and a support rod 20. A through hole is opened on the side of the power box 2, and the threaded rod 10 is rotatably installed in the through hole. The worm 12 is coaxially fixedly installed on the threaded rod 10. This configuration allows the worm 12 to follow the threaded rod 10 when it is in motion. The worm gear 10 rotates, and a worm wheel 18 meshes with the side of the worm gear 12. The bottom surface of the worm wheel 18 is fixedly connected to the top surface of the stirring shaft 13. This arrangement allows the worm wheel 18 to be driven by the worm gear 12, which in turn drives the stirring shaft 13 to rotate. The bottom of the stirring shaft 13 is installed inside the medicine chamber 1. The stirring shaft 13 can assist in mixing the medicine liquid in the medicine chamber 1, ensuring that the medicine liquid is mixed evenly. A push rod 15 is coaxially mounted on the worm gear 12. The push rod 15 is perpendicularly connected to the support rod 20. Both the push rod 15 and the support rod 20 are provided with inclined surfaces. The inclined surface of the push rod 15 cooperates with the inclined surface of the support rod 20. Moving the push rod 15 to the right can ensure that the support rod 20 rises. The top surface of the support rod 20 passes through the power box 2 and is fixedly connected to the feeding nozzle 8.

[0020] The power box 2 is also equipped with a controller 5, a control switch 4, and a display screen. The controller 5 is electrically connected to the control switch 4, the display screen, and the peristaltic pump 3. The controller 5 is connected to a mobile device via a Bluetooth module.
