Abstract
A portable battery-powered vibrating motor that can be clipped on any standard syringe provides vibration to a needle to be inserted into a patient to minimize discomfort. The clip is releasably attached to the syringe, and a holder connected to the clip releasably receives the motor. This enables the motor to be used on other units and enables the syringe and the clip to be sterilized, without the motor.
Claims13
An assembly to minimize pain to a patient when a needle is inserted into the patient, comprising:
- a vibrator including a housing;
- and
- a clip having a pair of spaced flexible legs joined by an end wall, which is fixed to said housing in a manner to cause the clip to vibrate, the clip legs being configured to spread and to releasably mount the vibrator directly on a syringe housing in a manner to support the vibrator on the syringe and to cause the syringe and a needle rigidly held by the syringe to vibrate as the needle is inserted into the patient.
An apparatus comprising
- a syringe having a generally cylindrical housing for receiving a capsule of liquid to be injected into a patient, said syringe having a needle fixed on one end, and a plunger on an opposite end for forcing the liquid through the needle into the patient;
- a vibrator including a housing;
- a clip mounted on an end of the vibrator housing in a manner to cause the clip to vibrate, said clip having a pair of spring legs that enable the clip and the vibrator to be removably fixed to and supported solely by the syringe housing in a manner to cause the vibration from the vibrator to be transmitted through the clip directly to the syringe housing so as to cause the syringe housing and the needle to vibrate.
