Description

Flushable tube double-chamber infusion device for offshore infusion

Technical Field

The utility model belongs to the technical field of medical instrument, a but marine infusion is with double room infusion set of wash-down pipe is related to.

Background

When a patient is transfused, in order to avoid that two adjacent infused liquids (drugs with incompatibility) have chemical reaction, so that adverse reaction of the patient is caused, a certain amount of normal saline with certain concentration is used for flushing the tube after one liquid is infused, and the second liquid is replaced to continue infusion after the flushing is finished. In order to prevent adverse reaction between two kinds of liquid medicines, the clinically infused liquid medicines and liquids need to be subjected to a tube washing operation.

In the current clinical infusion process, the medicine adding of an infusion bag is carried out on site, each patient needs at least three bags of liquid for infusion every day, and when the patient needs to wash the tube, a nurse needs to put a bag of finished 0.9% saline (generally 50mL) for washing the tube. Some hospitals can use 100mL or 250mL of saline without small bags, the flushing amount is generally 40mL-50mL, and the surplus saline can be discarded; if the next bag of liquid also needs to be flushed, the flushing of the tube is continued again with the remaining saline. When the liquid with the volume more than 50mL is used for flushing, the flushing volume can only be estimated in advance, a nurse wants to want to constantly want to, but forgets to replace the liquid in time when the nurse is busy, and the infusion time of the whole group of liquid is prolonged.

In the multi-chamber transfusion bag for clinical use, weak welding rods are arranged among chambers for isolation, namely, in the processes of production, transportation and storage, the components in a plurality of compartments of one transfusion bag are always isolated, and the liquid medicine is respectively placed in each chamber under a strict sterile environment. When in use, the weak welding rods are squeezed open among the chambers by external force, the chambers are communicated, the mixing process of the liquid medicines is completed within a few seconds, and the formed mixed liquid is directly used for patients. The product has the defect that liquid medicine mixing failure is caused to be invalid if the product is extruded by external force or the nurse acts too heavily in the transportation process.
