ABSTRACT:
A syringe and injection needle assembly with a gravity-responsive inclinometer for indicating the angle of inclination of the needle relative to a patient's skin. A plastic coupling tube for insertion between the syringe and needle of a conventional syringe and injection needle assembly and having means for mounting the inclinometer. The coupling tube may have an auxiliary inlet for receiving a second syringe, in which case a three-way valve is incorporated in the coupling tube for selectively providing fluid flow communication between the two syringes and the injection needle. The coupling tube may also be used without the inclinometer for the purpose of providing means for coupling a second syringe to the injection needle.
