Description

  The present invention relates to a waste container for used syringes, and more particularly, to a waste container for discarding a syringe after a patient self-injects at a place other than a hospital such as a home.

  In general, injections are often performed by specialists who are medical professionals such as doctors and nurses. For example, in the case of chronic patients such as diabetes and rheumatism, the patient himself / herself is treated at a place other than the hospital such as home. In some cases, drugs were self-injected. For example, in the case of advanced rheumatic patients, in order to relieve pain and suppress the progression of rheumatism, a treatment method is regularly carried out by self-injecting a therapeutic agent (adalimumab or etanercept) at home or the like.

  The syringe used includes an outer cylinder, an inner cylinder that can move in the axial direction in the outer cylinder, and an injection needle connected to one end of the outer cylinder. The therapeutic agent is filled between the outer cylinder and the inner cylinder, and is injected into the patient from the injection needle by pushing the inner cylinder in the axial direction with respect to the outer cylinder. A collar base is detachably attached to the other end of the outer cylinder of the syringe. The collar facilitates holding the syringe when the patient injects.

  A used syringe after self-injection performed outside a hospital such as a home needs to be finally discarded as medical waste from a medical institution. Therefore, the patient has stored the used syringe in a disposal container at home and brought the disposal container to a medical institution.

  Currently, medical institutions distribute waste containers provided by pharmaceutical manufacturers to patients as waste containers for used syringes. Such a waste container was not designed specifically for a specific self-injector, but used off-the-shelf products. Therefore, it is difficult to open and close the lid, it is difficult to use especially for advanced rheumatic patients who have difficulty in grasping things, such as pain and swelling that do not apply force to fingers, and large to carry There was a problem in use. In reality, bottles, cans, or Tupperware (registered trademark) at home have been used as waste containers. In such a container, the lid may not be securely closed, and there is a risk of the syringe popping out of the container when stored or brought to a medical institution. In addition, depending on the material of the substitute container, there is a risk that the injection needle penetrates the container. Therefore, there was a risk of needlestick accidents and secondary infections to third parties, including non-patient families or health care workers.

  Moreover, since the conventional disposal container cannot be reused, the medical institution has to discard the used syringe together with the disposal container. Conventional waste containers are large in size and costly for medical wastes borne by medical institutions. For this reason, medical institutions tended not to actively recommend the use of such waste containers.

  The present invention can prevent a needle stick accident to a third party and prevent secondary infection, can be safely brought to a medical institution, and is easy to use even for advanced rheumatic patients who do not have power on fingers, and has a size It is an object of the present invention to provide a waste container for a syringe used for self-injection, which is compact and can reduce the amount of medical waste discarded at a medical institution.

In order to achieve the above object, the present invention provides a waste container for a syringe used for self-injection in which a patient himself injects a therapeutic agent, wherein the syringe includes an outer cylinder and an inside of the outer cylinder in an axial direction.
