Description

Hospital medical waste dewatering device

Technical Field

The utility model relates to a medical waste's processing technology field, specifically speaking relates to a hospital medical discarded object dewatering device.

Background

Medical waste refers to waste products generated by medical and health institutions in medical, preventive, health care and other related activities with direct or indirect infectivity, toxicity and other harmfulness. Medical health institutions and medical waste centralized disposal units must comply with medical waste management regulations and conduct activities such as collection, transportation, storage, disposal, supervision and management of medical waste.

According to the regulation, the medical and health institutions in cities are required to timely deliver the medical wastes to the medical waste centralized disposal units for disposal according to the principle of the nearby centralized disposal. The medical waste centralized disposal unit disposes the medical waste, charges the medical waste disposal fee to the medical health institution according to the relevant national regulations, and the medical health institution pays the medical waste disposal fee according to the regulations.

In the case of Shanghai, there are currently 5800 more health and wellness institutions in Shanghai. In 2018, the department of property and price, the department of environmental protection, and the committee of health and family planning in Shanghai have jointly issued "notice on perfecting the charging mechanism for medical waste disposal" (hereinafter referred to as "notice"), giving two charging modes for medical waste disposal fees: the medical health institution and related units with beds can autonomously choose to pay the medical waste disposal fee according to the number of days that patients in the hospital actually occupy the beds or according to the weight of the medical waste. Secondly, medical and health institutions without inpatients and related units generate less than 100 kilograms of medical wastes on average per month, and medical waste disposal fees are paid according to quota; the average amount of medical waste generated per month is 100 kg or more, and the medical waste disposal fee is paid according to the weight of the medical waste. The charge standard of the medical waste disposal fee in 2018 is as follows:

table 1: 2018 annual medical waste disposal fee charging standard

The price of the charging standard is increased compared to before, increasing the cost of the health care institution in terms of medical waste disposal. For the health and medical institution who chooses to charge by weight, it is necessary to research a new scientific and reasonable concept of medical waste management and disposal to reduce the cost.

Although a great deal of literature reports the technologies related to the collection, transportation, storage, disposal and supervision management of medical wastes at present, the technologies are basically related to one of the links, and the economic expenditure in the aspect of processing the medical wastes by a medical and health institution is less considered. For example, patent document CN108960358A, published japanese 2018.12.07, discloses a medical waste weighing and recycling method and system, the method includes acquiring a medical waste collection request sent by a hospital department terminal; sending a medical waste collection request to a first intelligent mobile terminal of a collector; medical waste information sent by a first intelligent mobile terminal is obtained; medical waste information is stored in a system server database; medical waste confirmation information of the medical waste receiving responsible person; sending medical waste information to a second intelligent mobile terminal of a person in charge of a temporary storage room of a production waste unit; acquiring rechecking and warehousing information; sending medical waste information to a third intelligent mobile terminal of a receiving and transporting person of a disposal unit; acquiring code scanning and loading information of a third intelligent mobile terminal; sending the code scanning and loading information to a second intelligent mobile terminal; obtaining rechecking ex-warehouse confirmation information of the second intelligent mobile terminal; acquiring code scanning ex-warehouse information of a fourth intelligent mobile terminal of a responsible person of a disposal unit; and sending medical waste disposal information to a hospital department terminal. The technical scheme relates to supervision and management of medical wastes, and aims to realize traceable supervision of the whole process of the medical wastes. Patent document CN108332214A, publication No. 2018.07.27, discloses a medical waste treatment method using a medical waste treatment apparatus including an incinerator, a mixing tube, a primary adsorption chamber, a secondary adsorption chamber, a critical reaction chamber, and a separation chamber. The technical scheme relates to the treatment of medical waste, and aims to match a specific medical waste treatment method through the arrangement of a specific device, so that the existing known treatment method for treating the medical incineration fly ash by using critical water can realize the retreatment of smoke and water to achieve complete harmless treatment, and further, no secondary pollution is caused to atmosphere and water in the process of treating the medical waste. Patent document CN107777173A, open day 2018.03.09 discloses a categorised system of depositing for medical waste, including microcontroller, speech recognition module, a plurality of motor and a plurality of garbage bin of depositing side by side, microcontroller and speech recognition module install on the lateral wall of a garbage bin, every the garbage bin all includes base, shell body, upper cover and drive mechanism, the shell body bottom is located to the base, the upper cover is located the shell body top just upper cover one side is connected with the shell body hinge, drive mechanism one end articulates in the upper cover, and the other end is connected with the motor of installing in the base, speech recognition module is connected to the microcontroller input, and a plurality of motors are connected to the output. This technical scheme relates to medical waste's storage in the institute, aims at adopting the opening and the closure of artificial intelligence control garbage bin, satisfies the independent storage of different medical waste, avoids human contact, improves the security.

Therefore, a scientific, reasonable and comprehensive medical waste comprehensive treatment method which is based on the medical health institution, reduces the cost expenditure, simultaneously considers the environmental safety and accords with relevant regulations and is scientific, reasonable and comprehensive is not needed at present.

The applicant provides a scheme for dewatering and reducing weight of partial medical wastes in a medical and health institution through extensive and intensive research, but no device which is suitable for hospitals, has a good dewatering effect, and is simple in structure and convenient to use is available at present.
