Abstract
A plungerless aspiration and/or injection device and a method of using the same are disclosed herein. The plungerless aspiration and/or injection device includes a housing; a needle portion disposed in the housing, the needle portion configured to be selectively retracted and extended by a user, the needle potion comprising a needle tip configured to be inserted into tissue of a patient for aspiration, injection, and/or implantation; and a bulb portion disposed in the housing, the bulb portion defining a fluid containing cavity that is fluidly coupled to the needle portion, and the bulb portion being elastically deformable so that the user is able to perform the aspiration, the injection, and/or the implantation on the patient by manipulating the bulb portion.
Claims23
A plungerless aspiration and/or injection device, comprising:
- a housing;
- a needle portion disposed in the housing, the needle portion configured to be selectively retracted and extended by a user, the needle portion comprising a needle tip configured to be inserted into tissue of a patient for aspiration, injection, and/or implantation;
- and
- a bulb portion disposed in the housing, the bulb portion defining a fluid containing cavity that is fluidly coupled to the needle portion, and the bulb portion being elastically deformable so that the user is able to perform the aspiration, the injection, and/or the implantation on the patient by manipulating the bulb portion.
A method of using a plungerless aspiration and/or injection device, said method comprising the steps of:
- providing a plungerless aspiration and/or injection device that includes:
- a housing;
- a needle portion disposed in the housing, the needle portion configured to be selectively retracted and extended by a user, the needle portion comprising a needle tip configured to be inserted into tissue of a patient for aspiration, injection, and/or implantation;
- and
- a bulb portion disposed in the housing, the bulb portion defining a fluid containing cavity that is fluidly coupled to the needle portion, and the bulb portion being elastically deformable so that the user is able to perform the aspiration, the injection, and/or the implantation on the patient by manipulating the bulb portion;
- positioning the housing of the plungerless aspiration and/or injection device over a body portion of the patient;
- displacing the needle portion of the plungerless aspiration and/or injection device outward from the housing such that the needle tip penetrates the tissue of the patient;
- and
- compressing the bulb portion of the plungerless aspiration and/or injection device to either inject a fluid or implant into the tissue of the patient, or to aspirate a fluid biopsy from a body cavity or the tissue of the patient.
