Description

Technical Field

[0001] The utility model is a multi-purpose adapter for a T tube and an ENBD tube, belonging to the field of choledochal angiography examination. Background Art

[0002] When the patient's bile duct cannot be clearly displayed on ordinary X-ray films, medical contrast agents are generally used to enter the patient's bile duct through certain methods and channels, so that the outline of the bile duct imaging site and the lesion image can be clearly displayed on the X-ray film. This method is the cholangiography examination technology. Generally, T-tube and ENBD tube imaging are relatively common in cholangiography examinations. Generally, a syringe is used to draw the medicine from a container such as a medicine bottle, and then the needle of the syringe is connected to the T-tube or ENBD tube, and then the push rod of the syringe is squeezed to manually inject the medicine. The person pushing the medicine will inevitably be exposed to radiation during the examination, and cholangiography must be performed while the medicine is injected. The entire examination is a dynamic process and is closely related to the speed of drug injection. Manual injection of drugs cannot control the flow rate and causes radiation damage to personnel, which is easy to cause complaints. Utility Model Content
