Abstract

A disposable assembly within an extendable/retractable punching means addresses the problems of safety and convenience in needle techniques. The assembly enables a preset application in such assembly. The punching means comprises a punching needle and a recoverable pad. A housing pod of the assembly houses the needle and the recoverable pad. The needle is able to extend from the housing pod to puncture a subject and retract within the housing pod after puncturing. The assembly contacts and/or adheres to the subject when it is used. It may do puncture the needle, performance the preset application, and conceal the needle in one operating motion. The invention assembly avoids any potential risks associated with needle techniques: using no sterile needle, needle-stick, needle irritation, contamination and cross-infection. The assembly is of simple mechanism to easily make with economic benefits and to conveniently perform with fewer malfunctions.

Claims

1. A disposable automatic safety assembly comprising:

a housing pod;

an extendable/retractable punching means that comprises a punching needle and at least one recoverable pad disposed within said pod, said needle having a needle-body and a needle-head, and said needle-body being able to extend from said pod to puncture a subject and being able to retract within said pod after puncturing, said pad being able to change shape by pressure and recover without pressure; and

an application container within said pod, said application container housing applied component for a testing and/or delivery task;

an actuation mechanism that actuates said extension of said needle for performing testing and/or delivery task.

2. The assembly of claim 1, wherein said application container being configured for testing and/or delivery, the configuration of said application container includes at least one of the following:

inside of said pad, inside of said needle, inside of said pod or house of said pod.

3. The assembly as defined in claim 1 wherein said pad is made of flexible materials with recovery ability, said flexible materials including any foamed materials (e.g. foam rubber), any soft materials (e.g. soft rubber).

4. The assembly as defined in claim 1 wherein said pad is a mixed pad, said mixed pad being made of different materials, said mixed pad including either mixed by different soft flexible materials or mixed by flexible materials and firm springy materials.

5. The assembly as defined in claim 1, wherein said pad having room or rooms, said room(s) of pad serving as a needle tunnel and/or storing space.

6. The assembly as defined in claim 5 said pad having a penetrable member to close its tunnel or room(s) at the subject end of said pad.

7. The assembly as defined in claim 1 wherein said needle is a lancet needle having a sharp edge or point for piercing the surface of subject.

8. The assembly as defined in claim 7 wherein said lancet needle having two sharps on said needle-body, said one sharp being used for piercing the surface of subject and said other sharp edge(s) being used for breaking said penetrable member of said pad.

9. The assembly as defined in claim 1 wherein said needle is a test probe to directly take sample from said subject for said test task of assembly.

10. The assembly as defined in claim 1 wherein said needle is a hollow hypodermic needle in communication with said application container, said hollow hypodermic needle including that has a hole of needle at side of said needle-body.

11. The assembly as defined in claim 1 wherein said needle is a double-ends hollow needle in communication with said application container, said communication to said application container following said extension of said needle.

12. The assembly as defined in claim 1, wherein comprising a ring member in said housing pod for guiding said extension of said needle.

13. The assembly as defined in claim 1, further comprising a dressing portion on a bottom-surface of said assembly, said dressing portion being stuck said assembly on the surface subject.

14. The assembly as defined in claim 1, wherein said test container comprises means housing a test component for testing task, said test component being reacted with sample taken from said subject, and said test component being configured for an electrochemical measuring or optical measuring.

15. The assembly as defined in claim 14, wherein said test container is slid in house of said pod with said extension of said needle, said slide test container being pushed to the surface of subject for catching test sample from the surface of subject directly.

16. The assembly as defined in claim 1, wherein said delivery container in said pad comprises means for storing injectable substance (e.g. drug) to be delivered into said subject.

17. The assembly as defined in claim 1, wherein said delivery container within said needle-head comprises means for storing injectable substance (e.g. drug) to be delivered into said subject.

18. The assembly according to claim 1 further comprising a changer-member with a blocker is used to lock said needle at initial position and/or to set a preset depth of puncturing for said assembly.

19. The assembly according to claim 1 further comprising a readable marker on said assembly that provides information on said assembly that information includes at least one of a type of application container disposed within said assembly, a type of needle disposed within said assembly, a type of drug to be delivered using said assembly, and a type of said testing within said assembly.

21. The assembly of claim 20, said loading connector-site having electrode members for transfer electrical signal from said assembly to said associated device.

22. A method for using the assembly of claim 1:

applying said assembly to said subject;

performing said extendable/retractable punching means and said test and/or delivery task of said application container in one operating motion;

whereas said performing process includes taking sample from said subject for stored test component and/or delivering filled substance into said subject.

23. A method of an assembly within an extendable/retractable punching mechanism and an application container used by an associated device, the method comprising:

a. loading an assembly to an associated device;

b. applying said assembly to puncture area of subject;

c. performing said assembly by said associated device, said performing including extension of said needle for performance testing and/or delivery task of said application container, retraction of said needle within assembly, and catching performance result;

d. disconnecting said assembly, said disconnected assembly being either removed from said subject or stuck on said subject.

24. A disposable automatic safety assembly for healthcare comprising:

a housing pod;

an recoverable pad disposed within housing pod, said pad being able to change shape by pressure and recover without pressure;

a punching needle disposed within housing pod, said needle having a needle-body and a needle-head, and said needle-body being able to extend from said housing pod to puncture a subject and being able to retract within said housing pod after puncturing.
