Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a pollutant collection vehicle for hemodialysis rooms. Background Technology

[0002] Hemodialysis is an important treatment for patients with end-stage renal disease. As a high-risk medical facility, the hemodialysis room generates a large amount of medical waste containing pathogens, chemicals and sharps every day.

[0003] Traditional waste collection vehicles require medical staff to manually touch and open the lids of the waste containers. For example, Chinese utility model patent CN220360515U discloses a waste collection vehicle for hemodialysis rooms, including a vehicle body, a support frame, and a cloth bag. The cloth bag has an opening and is suspended from the support frame, which is connected to one side of the vehicle body. The support frame is rectangular and surrounds the opening of the bag. The support frame includes a frame rod and three frame plates, which are respectively located on the four sides of the support frame. The two ends of the frame rod are respectively connected to the two transverse frame plates on both sides. The device is equipped with a sliding groove and a movable plate on the support frame. The two ends of the movable plate move within the sliding grooves of the transverse frame plates on both sides, allowing the movable plate to move closer to and away from the longitudinal frame plates. Springs are installed at both ends of the movable plate, with the springs extending and retracting in the same direction as the movable plate's movement. A cover is connected between the movable plate and the frame rod, covering the bag opening. The cloth bag on the treatment cart can collect a large amount of medical waste during hemodialysis. After medical staff open the bag opening to dispose of medical waste, the bag opening can automatically close, preventing medical staff from forgetting to close the bag opening and causing medical waste to be exposed to the air, thus meeting hospital infection control requirements.

[0004] However, waste containers, especially the lids, can become contaminated with patient blood or waste chemicals from previous waste disposal procedures. When medical staff treat patients, they wear disposable gloves. Opening the lid contaminates the gloves, potentially transferring pathogens to the treatment equipment or the patient's skin, causing cross-infection. Therefore, medical staff must re-wear gloves and even disinfect their hands before proceeding with further treatment and care. Frequent glove changes and hand disinfection consume a significant amount of time, indirectly impacting the time available for direct patient care and reducing work efficiency. Therefore, to address these issues, a contaminant collection cart for hemodialysis units has been designed. Utility Model Content

[0005] The purpose of this invention is to enable the opening and closing of the cover without touching it by using a foot pedal to slide the slide rod downwards and a spring to slide the slide rod upwards. This solves the problem in the background art where medical staff have to use their hands to open the cover, causing their gloves to become contaminated. Medical staff then need to put on new gloves and even disinfect their hands before proceeding with further treatment and nursing procedures, which consumes a significant amount of their time and indirectly affects the time available for direct treatment and nursing care, thus reducing work efficiency.

[0006] The specific technical solution of this utility model is as follows: A contaminant collection vehicle for a hemodialysis unit includes a vehicle body with collection containers connected to its two side facades.
