Nasal feeding administration is one of the important ways of clinical nasal feeding tube patients, because oral solid medicine is not easy to dissolve in water, nursing staff usually put the solid medicine into a medicine grinding bowl to grind or use a medicine grinder to grind when taking oral medicine for the patient with the nasal feeding stomach tube, and finally, the powder medicine is poured into a medicine cup to be dissolved by warm boiled water and then nasal feeding is carried out on the patient. Chinese patent publication No. CN210146153U discloses a small size pulverizing machine for pulverizing oral medicines; chinese patent publication No. CN215197379U discloses a portable drug crusher for nasal feeding patients. The existing medicine crusher mainly comprises a cup cover, a rotating mechanism, a pull rope, a rotating shaft, a cup body and a crushing blade, wherein the rotating mechanism is arranged in the cup cover, the pull rope is in transmission connection with the rotating mechanism, the rotating mechanism is in transmission connection with the rotating shaft, and the crushing blade is arranged on the rotating shaft; the cup cover covers the cup body, the rotating shaft stretches into the cup body, and the rotating mechanism drives the crushing blade to rotate under the reciprocating pulling of the pull rope so as to crush solid medicines in the cup body, so that crushing of the solid medicines is realized; pulverizing the solid medicine, taking out, adding water, dissolving, and injecting into nasal feeding straight tube for patients to take medicine. The existing medicine crusher not only can manually pull the medicine to be crushed through the pull rope, but also can be an automatic medicine crusher for crushing solid medicines by driving a rotating mechanism through a motor.

From the above, at present, no matter what type of nasal feeding is adopted, solid medicines are firstly crushed, the crushed medicines are poured out for dissolution, and finally medicinal liquid is taken by a patient through a nasal feeding tube. The whole process brings inconvenience to nursing work, wastes time and labor, and also increases the risk of nursing medication safety. Therefore, the existing clinical nasal feeding solid medicine has the following defects and potential safety hazards: (1) The solid medicine is easy to splash due to improper force applied by using the medicine grinding bowl, so that the problems of waste and uncleanness are caused; (2) Some solid medicines have high density, the medicine grinding bowl cannot grind the medicine into powder, the crushed medicine particles have uneven size, and large particles cannot be dissolved in water to easily cause the blockage of an injection nipple and a stomach tube; (3) The phenomenon that a large number of patients are fed by nasal feeding in a severe department and share one medicine grinding bowl or medicine crushing machine is common, if the medicine grinding bowl and the medicine crushing machine cannot be cleaned, different medicines are easily used in series, and the risk of nursing and medication safety exists; (4) In the process of crushing the solid medicine, a small amount of powder is adsorbed on the bowl wall, the medicine grinding rod and the inside of the crusher, so that the medicine is wasted, and the dosage required by a patient is not reached; (5) The nursing staff needs to use different instruments in the process from smashing the medicine to dissolving the medicine to dosing, and the operation is tedious, so that the time consumption is long and the operation is laborious.

Therefore, a hand-pulled nasal feeding medicine crusher which is convenient to operate, ensures accurate nasal feeding medicine delivery and integrates medicine crushing, dissolving and holding into a whole and is specially used for nasal feeding medicine delivery is needed.
