Medical bag changing mechanism

Abstract

An embodiment of the present invention discloses a medical bag changing mechanism comprising a liquid supply portion, a plugging part and a liquid discharging part, the liquid supply portion includesa hanger for lifting a plurality of medical medicaments and a bracket detachably connected with a plurality of medical medicament outlet ports, the plugging part includes a first plugging machine anda second plugging machine, the bottom of the first plug-and-pull machine is slidably connected to the slide rail, the sliding rail is parallel to the support plate, and the first and second plugging machines each comprise a driving motor, a crank connected to the driving motor and a connecting rod connected with the crank, the connecting rod is provided with a needle tube holder at one end of theconnecting rod away from the crank, and the liquid outlet part comprises a first liquid outlet pipe, a second liquid outlet pipe, a needle tube holder of the first plugging machine and a second liquidoutlet pipe in parallel. The device effectively avoids the treatment interruption or artificial waste caused by replacing the new rinsing liquid bag in the minimally invasive cleaning process, can automatically complete the bag replacement without interrupting the supply of rinsing liquid, and ensures the continuous and sufficient supply of rinsing liquid.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical bag changing mechanism. Background technique [0002] At present, in the medical process, especially in the minimally invasive cleaning process, after a bag of cleaning solution is used up, a new cleaning solution bag is generally replaced by manual insertion and removal. This method either temporarily interrupts cleaning and replaces a new cleaning solution Continue cleaning after cleaning the bag; or a full-time medical staff is ready to replace the new cleaning solution bag at any time. The result is either a short interruption of treatment that affects the treatment effect or a waste of human resources. Since most of the cleaning solutions currently used in the minimally invasive cleaning process are quantitatively packaged in soft bags, a minimally invasive cleaning generally needs to be completed with two to three bags of cleaning solutions packed in sof...

Problems solved by technology

Although the liquid intake port of the cleaning solution in the soft bag package is made of hard plastic, since the packaging bag itself has no fixed shape, the position of the liquid outlet is not fixed, and when the force (the force generated by inserting and pulling out the infusion needle) The position of the liquid outlet will also change, and the liquid supply must not be interrupted during the cleaning process. Therefore, the technical problems that must be solved to realize the automatic bag changing technology are the relative fixation of the liquid outlet and the cross-changing bags, that is, when a bag of flushing liquid When it is about to run out, another bag of infusion needles has been inserted and is waiting
