Definitions
- the present invention relates to a safely operated multishot sidearm injection site using a needleless injector which is equipped with a main body and an extension sidearm and a cylindrical silicone valve body which is laterally disposed inside the main body and in abutment with the extension sidearm so as to seal a tubular injection tube disposed through the center of a microaperture valve stem disposed in the extension sidearm into which a needleless syringe is inserted with the valve stem protruding into the inside of the male member of a standard tapered Luer fitting of injection syringes.
- the principal characteristic of the present invention is the capability of prevention of embolisms as a result of air induction into the infusion delivery tube.
- a typical injection needle is connected to a dropper by way of a flexible rubber tube 10; and another improved Y shaped injection site is illustrated in Fig. 2 which is comprised of a main tube 11 and a branch tube 12 disposed at an angle at the side of and in-communication with the main tube 11.
- the branch tube 12 is sealed by a rubber cork 13.
- the main tube 11 is coupled to a delivery tube at each end.
- a nurse has to hold the injection syringe with a single hand and pierce the pointed needle thereof into the rubber tube 10 or the rubber cork 13 held by another hand; it is rather possible that the needle can accidently hurt the hand of the nurse, making the nurse easily affected when the wound is in contact with the blood of a patient who suffers from AIDS which is contagious to people via blood or human mucous membrane. Therefore, the prior art injection sites are not safe enough to operate especially in a time when AIDS is threatening the innocent people by accidental contacts.
- the primary object of the present invention is to provide a safely operated multishot injection site using a needleless injector to infuse medical solution into the delivery tube so that no accidents caused by pointed needles can happen.
- Another object of the present invention is to provide a safely operated multishot injection site using a needleless injector which is able to infuse medical solution into the injection delivery tube via a valve controlled injection tube so that no piercing holes will produce on the injection site and embolisms caused by the air induction into the infusion delivery tube can be prevented.
- Fig. 1 is a diagram showing a prior art injection needle for use in connection to a general dropper
- Fig. 2 is a sectional view showing a prior art Y shaped injection site
- Fig. 3 is a perspective diagram showing the exploded components of the present invention.
- Fig. 4 is a perspective diagram showing the assembly thereof
- Fig. 5 is a sectional diagram showing the structure of the present invention.
- Fig. 6 is a diagram showing the application of the present invention to a dropper system
- Fig. 7 is a sectional diagram showing the embodiment of • the present invention.
- Fig. 8 is a sectional diagram showing another embodiment of the present invention.
- the safely operated multishot injection site of the present invention is comprised of a main body 21, an extension sidearm 22 and a valve body 23 wherein the injection site is made of clear engineering thermoplastic of sufficient clarity and strength to provide visual observations of internal fluid flow and the valve body 23 is made of flexible silicone.
- the main body 21 is made in a tubular form with a tube 211 disposed therein and a laterally oriented through hole 212 in communication with the tube 211 of the main body 21 is integrally formed thereon for the insertion of the extension sidearm 22 into the main body 21.
- the extension sidearm 22 is in a tubular form and is provided with a closed end with a tapered inner wall 221 defined therein.
- An inward protruded valve stem 222 is disposed at the center of the closed end of the sidearm 22 and is provided with a tubular injection hole 223 through which the medical solution is infused into the injection delivery tube.
- a pair of lugs 224 are disposed at the periphery of the opposite end of the closed end.
- the valve body 23 is made in a cylindrical form and has . an outer diameter smaller than the smallest diameter of the through hole 211 so that when the valve body 23 is laterally disposed in the through hole 211, there is still room for the passage of medical solution.
- the extension * sidearm 22 is inserted into the laterally oriented through hole 212 of the main body 21 after the cylindrical valve body 23 is laterally located in the main body 21; and the closed end of the extension sidearm 22 is in abutment against the valve body 23 with the tubular injection through hole 223 sealed thereby.
- the present invention is connected to a dropper by way of closure piercing device 30, a filter device 31 is coupled to a volume controller 32 and the delivery tube 33 is extended therefrom; and the bottom end of the delivery tube 33 is connected to the present site 20, and another delivery tube 33 is coupled to an injection needle at the end of the dropper system.
- a needleless syringe 40 taking the solution from a medical container is used to infuse the same into the dropper system.
- the protruded end 41 of the syringe 40 is inserted into tapered through hole 221 of the extension sidearm 22 with the valve stem 222 inserted into the hole of the protruded end 41.
- the nursing personnel are free from the risk of being fatally affected as a result of hurting by needles.
- the injection syringe can be firmly retained in place due to thy additional threads on the protruded end of the syringe which is attached to the lugs of the extension sidearm.
