Description

Fixing device for venous transfusion device

Technical Field

Background

Intravenous infusion therapy is the main treatment for hospitalization of patients, and a scalp steel needle can only be used for single dose administration and is not indwelling according to 2016 edition of INS (infusion therapy practice standard) guidelines. Clinically, short peripheral venous catheters, medium-length catheters and central venous catheters are mainly adopted to finish infusion treatment. The needleless positive pressure joint is used as a pivot for connecting the infusion apparatus and the vascular access device, so that the invasion of microorganisms into the vascular access device can be effectively organized, and the needleless design greatly reduces the occurrence of needle-prick injury of nursing staff, thereby being widely used clinically.

The method for connecting the needle-free positive pressure joint with the infusion apparatus comprises the following steps: the nipple end of the infusion apparatus is jacked into the nut end of the positive pressure connector and then is rotated by 90 degrees clockwise (tight connection), and at the moment, the infusion apparatus, the positive pressure connector and the remaining needle are connected into a whole. However, in the process of infusion, due to the reasons that the patient moves excessively, the nurse does not patrol in place and the like, the phenomenon that the positive pressure connector is separated from the screw cap end of the infusion apparatus often occurs, so that not only is the waste of liquid medicine caused, but also the whole infusion apparatus is polluted, the infusion apparatus needs to be replaced again, the material use cost of the patient is increased, and the workload of the nurse is increased. And on the fixation of the infusion apparatus pipeline, the disposable infusion adhesive plaster is clinically used to be adhered on the skin of a patient, and the needle-free positive pressure connector is fixed at the position of about 5cm above the needle-free positive pressure connector. The adhesive paste is used for fixing the far end, so that the comfort of patients is reduced, and some patients can have the condition of allergy of the adhesive paste, thereby increasing the pain of the patients. And take an ultra-low density polyethylene infusion apparatus as an example, the length of the ultra-low density polyethylene infusion apparatus is 160cm (the distance from the far end of a needle inserted into an infusion bottle to a nipple of the infusion apparatus), the weight of the ultra-low density polyethylene infusion apparatus is 22g (a scalp intravenous needle is removed and a needle protecting cap of the needle inserted into the infusion bottle), the condition that the fixation is not firm can occur when one piece of paste is fixed, a patient can repeatedly require a nurse to replace the paste, the workload of the nurse is increased, and unnecessary waste is caused.
