A foot-operated drug crushing device for tumor care

Abstract

The invention discloses a treadle-type medicine breaking device for oncologic nursing, and belongs to the field of medical apparatuses and instruments. The treadle-type medicine breaking device for oncologic nursing comprises a medicine smashing groove, a medicine smashing pestle, a support device used for installing and fixing the medicine smashing groove, a medicine smashing drive device used for driving the medicine smashing pestle to move up and down, a rotation drive device used for driving the medicine smashing groove to rotate, and a protection layer used for preventing medicines from splashing, wherein the medicine smashing drive device and the rotation drive device use one power source mechanism in common, and drive the medicine smashing pestle and the medicine smashing groove through two transmission paths separately; and the medicine smashing groove comprises a groove main body, a hemispheric filter screen, a support column, a medicine powder collection hole and a medicine powder collection box, and the protection layer is made from a transparent material, and surrounds the periphery of the upper end of the hemispheric filter screen. The treadle-type medicine breaking device for oncologic nursing is composed of reasonable and ingenious pure mechanical mechanisms, without the participation of electric power; the breaking action intensity for the medicines can be increased; and adequate and reasonable utilization for the force applied by the medicine smashing pestle is benefited, and uniformizing for the thickness of the broken medicine powder is facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a foot-operated drug crushing device for tumor care. Background technique [0002] Most cancer patients are suffering from long-term pain, resulting in poor swallowing ability. They are prone to choking on water and gunpowder when feeding tablets, and in severe cases, they may be inhaled into the trachea by mistake, making the work of feeding drugs a serious threat to the life safety of patients. For the safety of patients, all solid medicines need to be ground into powder and then brewed and taken. Generally, the oncology department is not equipped with a dedicated drug crusher, so medical staff need to grind the drug manually, which is troublesome. [0003] The emergence of the crushing device can solve the above-mentioned trouble of manually grinding medicines. At present, most of the existing drug crushing devices only achieve the purpose of crushing drugs by crushing the dru...

AI Technical Summary

Problems solved by technology

At present, most of the existing drug crushing devices only achieve the purpose of crushing drugs by crushing the drug in the drug pounding tank with a pestle. For example, the patent document with the authorized announcement number CN 205434401U discloses a foot-operated tumor care device. The medicine crushing device acts on the pedals through manpower, and realizes the medicine pounding action of the medicine pestle through the connecting rod transmission. Obviously, its work efficiency is low

And the authorized announcement number is that the patent document of CN206081072U discloses a kind of crushing device that the medicine trough rotates when the medicine pestle rams medicine, and it drives the medicine trough and the medicine pestle respectively by a rotating motor and a vibrating motor. Electricity dependent, cannot be applied without power supply

In addition, the existing drug crushing device mechanically performs a pounding action during the drug crushing process. In the later stage of drug crushing, the drug powder that has reached the standard (the thickness meets the requirements is defined as the standard) and the drug particles that have not reached the standard are mixed together. When there are many drug powders that have reached the standard, they will cover the surface of the drug particles that have not reached the standard, and play a certain "protective effect" on them, so that the drug powder that has reached the standard will continue to be crushed, while the drug particles that have not reached the standard will continue to be crushed. weakened

That is, there is the problem of improper action of the force, and the use of the force applied by the pestle is not sufficient and reasonable, which slows down the working efficiency of the device, and is not easy to unify the thickness of the crushed drug powder
