Description

Medical trash can

Technical Field

The invention relates to the technical field of medical supplies, in particular to a medical trash can.

Background

As a novel vaccination unit, the mobile vaccination vehicle has the characteristics of strong maneuverability and high efficiency. The most obvious advantage is that the vaccine can go deep into places such as schools, communities, enterprises and public institutions and the like, and provides quick, safe and efficient vaccination service for people in need. Due to the limited space of the vaccination vehicle and the large number of the personnel for vaccination, the medical waste generated by the vaccination vehicle is large in volume. Personnel on the inoculation vehicle are generally only provided with medical personnel, but do not have personnel specially collecting and releasing garbage, the workload of the medical personnel during inoculation is large, the medical personnel can not take a body specially to collect and release medical garbage, moreover, the medical garbage contains a large amount of bacteria and viruses, and has the characteristics of high pollution, high danger, high infectivity and the like, if the medical personnel collect and release the garbage in the process of inoculation, cross infection is easily caused, and adverse effects are caused to the inoculation personnel and the medical personnel.

The existing medical garbage can garbage bag needs medical staff to manually seal the garbage bag after being filled with garbage, and is operated by special personnel or in spare time in common medical places, and disinfection facilities are more sound, and the problem is not serious. But in the special environment of a vaccination car, the risk of cross-infection is greatly increased. That is to say, current medical trash can if use not only can increase medical personnel's work load on the vaccination car, the extension with the time of medical waste contact, still increased medical personnel's infection risk, improper handling will constitute huge threat to medical personnel and vaccinator's health and life safety.

The garbage can capable of being automatically sealed exists in the field of daily living goods, for example, Chinese patent with application publication number CN111361891A discloses a garbage bag sealing device of a household intelligent garbage can, which is provided with a contraction rope, the contraction rope is wound and woven between a rotary bearing and a contraction rope fixing sleeve, when the rotary bearing rotates, the contraction rope is tensioned and gathered to the center, when the rotating bearing is reset, the contraction rope is scattered, the heating device is wrapped outside the contraction rope and is connected with a power supply system, namely, in the proposal, the garbage bags are tightened by the contraction rope and then sealed by the heating device, however, not all the garbage bags can be sealed by heating, the material of the garbage bag is required, in addition, the heating sealing mode is slow, the energy requirement is high, and the garbage bag is easily damaged after being heated seriously, so that the leakage risk of medical garbage is caused.

Chinese patent application publication No. CN 104192456a discloses an automatic sealing garbage can, be provided with throat mechanism, throat mechanism includes the second arc pole of two symmetrical arrangements and the first arc pole of two symmetrical arrangements, at first utilize first arc pole and second arc pole to draw in the disposal bag sack, then utilize first sticky tape and second sticky tape on the first arc pole to pull the disposal bag sack and seal, that is to say, this scheme is the mode that utilizes the sticky tape to seal, however, at the environment periphery of garbage can, the sticky tape is very easy to glue miscellaneous article and influence and paste the effect, or, after the disposal bag is placed, the sticky tape is probably to paste on the disposal bag promptly and influence the pasting after sealing, consequently, the mode of sticky tape has a lot of uncertainties, and probably lead to sealing not tight or not sealing, finally cause the leakage risk.
