Needleless sampling catheter

Abstract

The invention discloses a needleless sampling catheter. The needleless sampling catheter includes a main urinary catheter, a branch urinary catheter and a sampling tube; the branch urinary catheter and the sampling tube communicate with the main urinary catheter; a urinary hole is formed in the main urinary catheter; the needleless sampling catheter also includes a supporting structure, a urinarycollection container, a lifting structure and an opening-closing structure; the supporting structure includes a support platform, a support column, a support rod, a first connection rod, a second connection rod and a third connection rod; the lifting structure includes a first electromagnet, a first iron block and a first button switch; and the opening-closing structure includes a fourth connection rod, a fifth connection rod, a second electromagnet, a second iron block, and a second button switch. The needleless sampling catheter can facilitate sampling and improve the accuracy of the detection result; when urine in the sampling tube is updated, only the button switch is pressed so as to prevent medical personnel from contacting the patient's urine or prevent urine spilling; and the needleless sampling catheter is easy to operate, and is safe and clean.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a needle-free sampling urinary catheter. Background technique [0002] In clinical care, when collecting urine specimens for urinary retention or dysuria, it is necessary to take samples from the catheter. Usually, a sterile syringe is used to draw urine from a sterilized sampling port to obtain a small amount of samples. The sampling port is generally It adopts an elastic plug, and uses a sterile syringe to pass through the wall of the drainage tube or the elastic plug to take samples. This sampling method exposes medical staff to potential needle-stick injuries and is also easy to contact with urine. The sterile syringe also needs to reinject the sample into the In test tubes or petri dishes, increasing the chance of contamination. [0003] When obtaining a sample from the urinary catheter, it is desirable to obtain the latest sample. The urine discharged b...
