External-application medicine sub-packaging device

Abstract

The invention discloses an external-application medicine sub-packaging device and belongs to the field of medical devices. The external-application medicine sub-packaging device is characterized by comprising a frame, a discharge hopper, a bucket conveyor, a collecting hopper and a weighing and packaging assembly. A support spring is arranged under the front end of the discharge hopper. The bucket conveyor is located on the rear lower portion of a discharge hopper opening and comprises a drag chain, small hoppers, a head wheel, a tail wheel, a gear and a connecting plate. The drag chain is wound on the head wheel and the tail wheel. The small hoppers are fixed on the periphery of the drag chain. The collecting hopper is located in front of the tail wheel. The weighing and packaging assembly comprises a first disc holding rack, a second disc holding rack, a third disc holding rack, a first crossbeam, a second crossbeam, a connecting rod and a rider. The first disc holding rack and the second disc holding rack are fixed to the frame. The third disc holding rack is fixed to the rear end of the first crossbeam. Compared with the prior art, the external-application medicine sub-packaging device has the characteristic of convenient and accurate sub-packaging.

Description

technical field [0001] The invention relates to a medical device, especially a device suitable for dispensing preparations in hospitals. Background technique [0002] External application of traditional Chinese medicine is a commonly used conservative treatment method for vascular surgery diseases. The preparation room of each hospital often has relevant proven prescriptions for batch configuration. For the convenience of use, the bulk medicine needs to be evenly divided into multiple parts by weight. However, in the existing technology, drug dispensing includes two methods: manual dispensing and mechanical dispensing. Traditional manual dispensing and weighing are time-consuming and laborious, while in mechanical dispensing, when the medicine falls into the dispensing box, it will cause impact on the dispensing box. , the impact will interfere with the weighing process. In order to make the weight accurate, it is common practice to measure the size of the impact force thro...

AI Technical Summary

Problems solved by technology

During the mechanical subpackaging process, various factors such as the type of drug, particle size, the amount of remaining drug in the hopper, drug humidity, drug viscosity, etc. will affect the feeding speed, resulting in unstable feeding speed. The change will cause the magnitude of the impact force to change, and the change of the magnitude of the impact force will cause errors in the measurement of the weight of the medicine in the sub-package box, resulting in inaccurate and uneven sub-package weights
