Drug pulverizer

Abstract

The invention discloses a drug pulverizer. Pulverizing blades are driven by an electric control device to pulverize drugs and no manual operation is needed, so that the operation is simple, convenient, time-saving and labor-saving, and the work efficiency is improved; the drugs are mainly pulverized in the feed cavity of a housing, so as to avoid the phenomena of leakage, contamination and the like; the pulverizing effect is better; a filter screen is arranged to block bigger particles for re-pulverizing, so that the pulverizing fineness is higher; during operation, no dust is produced and the noise is lower, so as to ensure the environmental quality; and the internal of the housing is smooth and free of the problems of residual and the like, so that the cleaning is convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a medicine pulverizer. Background technique [0002] Crushing refers to the process of breaking large solid materials into small pieces or powder by means of mechanical force. [0003] Most of the clinical inpatients need oral medication to help control the disease. There are various kinds of drugs, including granules (commonly known as tablets), capsules (divided into hard capsules and soft capsules), powders, etc., which are administered by nurses every day. Distribute it to each patient and assist them to take it with warm water. However, for some departments of the hospital, such as intensive care unit, neonatology, neurology and cardiology, or some nursing homes, nursing homes, etc., the concentration of the elderly, children and certain diseases (such as stroke, coma, etc.) lead to dysphagia or need For patients with nasal feeding, oral western medicin...

AI Technical Summary

Problems solved by technology

The use of such instruments is time-consuming and laborious, and the crushing effect is not good. The incompletely crushed large particles cannot be completely dissolved in water. When injected into the nasogastric tube, it is easy to accumulate and block the outlet of the nasogastric tube and the side hole of the tube wall. Gastric tube blockage requires extubation and reinsertion, which increases the patient's pain and financial burden; the design of the cylindrical tubular structure and inner wall frosting, threads, bumps and other aids in grinding is prone to drug residues and inconvenient cleaning, resulting in the actual medication taken by the patient. The dose changes, which affects the control and recovery of the patient's condition; the extrusion principle can only crush the tablet, but it is inconvenient for the capsule, which increases the manual workload

In addition, most of the existing designs are not airtight during the grinding process, which is easy to lose the drug and increase the possibility of contamination by impurities

Although some have been improved, such as adding a cover or a sealing film, most of the designs still have the disadvantage that the tablet fragments are easy to pop out or easily mixed with impurities

There are also some equipment with small motors that use two oppositely rotating rollers to crush and grind, but it is not suitable for capsules, and the motor is driven by a hand crank. The operation is time-consuming and laborious, and the drug particles tend to stay on the rollers and do not go down.
