Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a medicine powder dividing device. BACKGROUND

[0002] In life, a whole bag of medicine powder is often bought, and then the medicine powder is weighed according to actual conditions and the medicine amount prescribed by a doctor before being eaten, which is more common in pet medicine. Since the weight of each pet is different, the required medicine amount is also different, and the corresponding medicine amount of capsules cannot be prepared in advance for direct use, and generally, a pet doctor provides a large bag of medicine powder, and then the owner weighs the appropriate amount of medicine powder according to the weight of the pet and feeds the pet, but the efficiency of manually weighing and dividing the medicine powder is low, and the accuracy is also difficult to grasp, and there may be the situation of weighing too much or too little.

[0003] In medical practice, drug dispensing often faces the challenge of personalized dose management. Due to significant weight differences among individuals, pharmaceutical companies have difficulty in pre-preparing standardized dose units. The current solution mainly uses large-scale pre-packaged medicine powder, and patients need to perform dose dispensing operation through traditional weighing tools. This manual dispensing method has double technical defects: first, the operation efficiency is low, and it takes about 3-5 minutes for single dispensing and needs to be calibrated repeatedly; second, the dose accuracy is difficult to guarantee, and the ±5-10% dispensing error caused by conventional household electronic scales (accuracy ±0.1g) may affect the drug peak concentration compliance rate (Cmax difference can reach 15%). Especially in the use of narrow therapeutic window antibacterial drugs (such as doxycycline) or antiepileptic drugs (such as phenobarbital), such errors may cause treatment failure or risk of toxic side effects.

[0004] Chinese utility model patent (publication number CN210311238U, application date 2019.05.09, publication date 2020.04.14) discloses a kind of quick equal division device of medicine powder, it is characterized by: including medicine distribution box, baffle, equal division seat and base, at least one row of horizontal setting capsule fixed seat is formed on the base, the equal division seat is detachably connected with base by vertically arranged connecting column, the lower end surface of the equal division seat is formed with a row of equal division funnel parallel with the capsule fixed seat, the lower end of each equal division funnel is abutted with the upper end of the capsule fixed in the corresponding capsule fixed seat, the medicine distribution box is detachably fixed on the upper side of equal division seat, the medicine distribution box is provided with medicine distribution funnel matched with equal division funnel, the baffle is slidably arranged between medicine distribution box and equal division seat and separates medicine distribution funnel from equal division funnel.Its working principle is as follows: first, place the capsule needing medicine powder into the corresponding capsule fixed seat, then connect the equal division seat and base assembled with baffle and medicine distribution box through connecting column, and make the lower end of the equal division funnel of the equal division seat abut with the upper end of the capsule, pour the medicine powder into the medicine distribution funnel, scrape the medicine powder horizontally with the scraper of medicine distribution rod, make the upper surface of the medicine powder horizontal, and continuously add the medicine powder until the height of the medicine powder reaches the corresponding scale bar, then pull the baffle to make the medicine powder fall into the capsule through the equal division funnel, after the medicine powder completely falls into the capsule, take out the equal division seat, cover the capsule cover to obtain the capsule with equally divided medicine powder, which is simple and convenient to operate.

[0005] The equal division device has the following disadvantages: 1. The medicine distribution funnel has a large area, and it is difficult to ensure that the upper surface of the medicine powder is horizontal when the scraper is used to scrape the medicine powder. Experimental tests show that the horizontal error of the surface of the medicine powder is ±5%; 2. When the added amount of the medicine powder exceeds the scale, the upper surface of the medicine powder needs to be scraped off and then scraped flat, which is relatively troublesome to operate.
