The present invention relates to a drug injector adapter, and more particularly, to a drug injector adapter that is configured to be attachable to and detachable from a needleless drug injector and has a structure that allows a needle to be coupled to the needleless drug injector.
A drug delivery system is used to deliver drugs to the human body for various purposes, such as treatment of human diseases, wounds, or beauty, and an injection method using a needle is most often used due to its safety and efficiency.
However, although a drug delivery system using a needle enables accurate and efficient drug administration, it may cause patients to have injection phobia due to pain during injection. In addition, the drug delivery system using a needle also have problems such as the risk of infection due to reuse of needles and the generation of large amounts of medical waste.
Accordingly, development of structures for delivering drugs to the human body without a needle continues. However, because the structures for delivering drugs to the human body without a needle also have pros and cons, there is still a need for a structure capable of mixing a needle as needed.
The present invention provides a drug injector adapter that is configured to be attachable to and detachable from a needleless drug injector and has a structure that allows a needle to be coupled to the needleless drug injector.

A first storage portion 110 inside the first housing 100 may be filled with pressure generating liquid 10.
The pressure generating unit 120 is located at the top of the first storage portion 110 to maintain a sealed state of the first storage portion 110, and may concentrate and apply energy toward the pressure generating liquid 10.

The optical system 122 may integrate the laser beam generated by the pressure generating unit 120 and transmit it to the pressure generating liquid 10.
The pressure generating liquid 10 may expand in volume by energy (e.g., laser beam) applied from the pressure generating unit 120. An elastic membrane 130 is stretched according to the volume expansion of the pressure generating liquid 10. According to the extension of the elastic membrane 130, a drug solution 20 stored in a second storage portion 210 and a third storage portion 310, which will be described later, may be injected through a flow passage 500 and an injection flow passage 610 of a nozzle 600.

According to an embodiment, the pressure generating liquid 10 may be implemented as a reflector, a liquid mixed with opaque materials, or an opaque liquid. Accordingly, because high energy (e.g., a laser beam) generated from the pressure generating unit 120 penetrates the elastic membrane 130 and reaches the drug solution 20, the drug solution 20 may be prevented from being deteriorated.
According to an embodiment, the pressure generating liquid 10 may be implemented as various liquids such as water, alcohol, or polyethylene glycol. According to an embodiment, the pressure generating liquid 10 may be implemented as a liquid material of various shapes such as sol or gel.

The second storage portion 210 may be formed in a hollow form with open upper and lower parts. The upper part of the second storage part 210 may be sealed by the elastic membrane 130, and the lower part of the second storage part 210 may be in communication with the third storage part 310 of the chamber 300.
The injector 220 may be coupled to the outside of the second housing 200.
The side of the second storage portion 210 may have a fluid migration path communicating with an injection passage 222 of the injector 220.
The drug solution 20 may be supplied to the second storage portion 210 and the third storage portion 310 through the injection passage 222 of the injector 220.
According to an embodiment, when at least a portion of the drug solution 20 is injected, the injector 220 supplies the drug solution 20 so that the second storage portion 210 may be filled with the drug solution 20 by the amount injected.
The chamber 300 is coupled to a lower part of the second housing 200, and the third storage portion 210 filled with the drug solution 20 may be formed inside the chamber 300.
The flow passage 500 that forms a migration path for the drug solution 20 pushed out from the third storage portion 310 may be provided at a lower part of the third storage portion 310.
The drug solution 20 moved through the flow passage 500 may be injected through the injection flow passage 610 of the nozzle 600.

Referring to
The body 700-1 of the drug injector adapter 700 may include a delivery flow passage 705, a first sealing portion 710, a fixing portion 720, a support portion 730, a first coupling portion 740, a second sealing portion 750, and a second coupling portion 760.
The delivery flow passage 705 may form a path for moving drugs between the flow passage 500 of the drug injector 1000 and a flow passage 820 of the needle 800.
The fixing portion 720 may be inserted into a position (e.g., the insertion groove 305) where the nozzle 600 was removed from the drug injector 1000 to fix the drug injector adapter 700.
According to an embodiment, the fixing portion 720 and the insertion groove 305 may be coupled in various ways, such as a screw coupling method or a fitting coupling method.
The first sealing portion 710 may be formed at the end of the fixing portion 720. The first sealing portion 710 may be configured so that the fixing portion 720 may be in close contact with the insertion groove 305 of the drug injector 1000.
When the drug injector adapter 700 is coupled to the drug injector 1000, the first sealing portion 710 may be in close contact between the fixing portion 720 and the insertion groove 305 to connect the delivery flow passage 705 of the drug injector adapter 700 and the flow passage 500 of the drug injector 100 in a tightly sealed state.
According to an embodiment, the first sealing portion 710 may be formed of an elastic material.
The support portion 730 may be configured to be in close contact with an outer surface of the drug injector 1000 (e.g., an outer surface of the chamber 300) when the fixing portion 720 is inserted into the position (e.g., insertion groove 305) where the nozzle 600 of the drug injector 1000 was removed. The support portion 730 may support the outer surface of the drug injector 1000 (e.g., an outer surface of the chamber 300) to prevent the drug injector adapter 700 from being excessively inserted into the drug injector 1000.
The first coupling portion 740 may have a coupling structure for coupling the adapter housing 700-2.
According to an embodiment, the adapter housing 700-2 may be coupled to the first coupling portion 740 in various ways, such as a screw coupling method or a fitting coupling method.

The coupling member 770 may firmly fix the needle 800 when it is inserted into the coupling groove 700-2H. According to an embodiment, the coupling member 770 may be formed of an elastic material. According to an embodiment, the coupling member 770 may firmly fix the needle 800 by forming a groove in a portion corresponding to a protrusion 812 of the needle 800.
When the drug injector adapter 700 is coupled to the needle 800, the adapter housing 700-2 may include the second sealing portion 750 that is in close contact with the delivery flow passage 705 of the drug injector adapter 700 and the flow passage 820 of the needle 800 to connect them in a tightly sealed state.
According to an embodiment, the second sealing portion 750 may be formed of an elastic material.
The needle 800 may include a body portion 810 and the flow passage 820.
The body portion 810 of the needle 800 may include an insertion groove 810H into which the second coupling portion 760 of the drug injector adapter 700 can be inserted. The second coupling portion 760 of the drug injector adapter 700 may have a protruding structure corresponding to the insertion groove 810H.
According to an embodiment, the protrusion 812 may be formed on the body portion 810 of the needle 800. At this time, the protrusion 812 may be in close contact with the wall of the adapter housing 700-2 of the drug injector adapter 700 or a groove formed in the coupling member 770, and may be firmly coupled to the drug injector adapter 700.
According to an embodiment, because the drug injector adapter 700 is coupled to the drug injector 1000 and the needle 800, the flow passage 500 of the drug injector 1000, the delivery flow passage 705 of the drug injector adapter 700, and the flow passage 820 of the needle 800 may be connected to each other. Accordingly, a drug solution ejected from the drug injector 1000 may be injected into the human body into which the needle 800 is inserted through the delivery flow passage 705 of the drug injector adapter 700 and the flow passage 820 of the needle 800.
