Description

Technical fields:

[0001] This utility model belongs to the field of medical waste sorting and recycling technology, and more specifically relates to a medical waste sorting and recycling nursing vehicle. Background technology:

[0002] In the healthcare industry, hospitals generate a large amount of medical waste daily. Traditional medical care carts have a relatively limited function, often focusing only on the collection and transportation of medical supplies, lacking a systematic and effective design for waste sorting and recycling. Commonly, various types of waste are mixed together in ordinary trash cans, which not only violates regulations requiring strict sorting and disposal of medical waste but also easily leads to serious problems such as cross-contamination. For example, mixing infectious waste with recyclable medical waste can allow bacteria and viruses to spread more widely, increasing the risk of infection for medical staff, patients, and others.

[0003] Some existing nursing vehicles that claim to have waste collection functions have also revealed many shortcomings in actual use. Their waste collection areas are usually not meticulously and reasonably divided, and cannot meet the separate storage needs of different types of medical waste, such as infectious waste, sharps waste, and pharmaceutical waste. Taking sharps waste as an example, if it is mixed with other waste, staff are very likely to be pricked by needles, blades, and other sharp objects during subsequent processing, which could lead to the spread of diseases. Utility model content:

[0004] To address the aforementioned problems and overcome the shortcomings of existing technologies, this utility model provides a medical waste sorting and recycling nursing vehicle;

[0005] The first technical problem to be solved is that mixing different types of waste, such as infectious waste, sharps waste, and pharmaceutical waste, may allow bacteria and viruses to spread to a wider range, increasing the risk of infection for healthcare workers, patients, and other personnel.

[0006] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: a medical waste sorting and recycling nursing vehicle includes a nursing vehicle body, the bottom of the nursing vehicle body is provided with universal wheels with locking function, and the interior of the nursing vehicle body is divided into a medical item storage area and a waste storage area distributed vertically by a first horizontal partition, the medical item storage area being located above the waste storage area;

[0007] The waste collection area is divided into a recyclable medical waste area and a medical waste area by vertical partitions. The medical waste area is further divided into infectious waste compartments, sharps waste compartments, and pharmaceutical waste compartments by a second horizontal partition.
