Acupuncture needle and needle guide assembly

Claim 2

An acupuncture needle and needle guide assembly comprising: a needle; an elongated handle having a first axial portion secured to one end of said needle; a tubular housing having a first bore portion appropriately dimensioned to frictionally engage said first portion of said handle, and a second elongated portion adjacent said first bore portion and dimensioned to enclose said needle therein; first means for manually slidably displacing said handle in a direction toward said second portion of said housing; and second means for restricting displacement of said handle in a direction away from said second portion of said housing.

Claim 3

The invention as defined in claim 1 wherein said first means comprises a second axially extended portion of said handle secured to said first portion of said handle.

Claim 4

The invention as defined in claim 1 wherein said first bore portion is tapered radially inwardly in a direction away from said second portion of said housing and said first portion of said handle is correspondingly tapered.

Claim 5

The invention as defined in claim 2 and further comprising a tubular end cap having a central bore adapted to receive said second handle portion and removably received over the periphery of said first portion of said housing.

Claim 6

The invention as defined in claim 4 wherein said first portion of said housing is formed with a reduced peripheral cross-section to thereby define an abutment surface intermediate said first portion of said housing and said second portion of said housing, and wherein an axial end of said end cap rests against said abutment surface.

Claim 7

The invention as defined in claim 1 and further comprising a tubular end cap removably received over the periphery of the end of said second housing portion.

Claim 8

The invention as defined in claim 6 wherein said end of said second housing portion includes a reduced cross-sectional, peripheral portion which defines an abutment surface and wherein an axial end of said end cap rests against said abutment surface.

Claim 9

The invention as defined in claim 7 wherein said tubular end cap is axially longer than said reduced cross-sectional, peripheral portion.

Claim 10

The invention as defined in claim 3 wherein said first means comprises a second axially extended portion of said handle, wherein said second portion of said handle is cylindrical and peripherally dimensioned substantially the same as the narrowest portion of said first portion of said handle.

Claim 11

The invention as defined in claim 1 and in which said handle is tapered with a reduced diameter at its outer end and to facilitate disengagement with said tubular housing.

Claim 12

The invention as defined in claim 4 and further comprising a second tubular cap removably received over the periphery of the end of said second housing portion.

Claim 13

The invention as defined in claim 6 and further comprising fluid passage means intermediate the periphery of said housing and said tubular cap for enabling air to communicate between the interior and exterior of said housing during sterilization.

Claim 14

The invention as defined in claim 4 and further comprising fluid passage means intermediate the periphery of said housing and said tubular cap for enabling air to communicate between the interior and exterior of said housing during sterilization.

Claim 15

The invention as defined in claim 11 and further comprising fluid passage means intermediate at least one of said tubular end caps for enabling air to communicate between the interior and exterior of said housing during sterilization.

Claim 16

The invention as defined in claim 3 wherein said first portion of said handle is conical.

Claim 17

An acupuncture needle and needle guide assembly comprising: a needle, an elongated handle having a first axial portion secured to one end of said needle, an open ended tubular housing having a first portion with a tapered inner bore which is dimensioned to frictionally engage said first portion of said handle and a second elongated portion adjacent said first bore portion and dimensional to enclose said needle therein, first means for manually, slidably displacing said handle in a direction toward said second portion of said housing, at least one tubular end cap covering an end of said tubular housing and, fluid passage means intermediate said at least one tubular end cap and said housing for enabling air to communicate between the interior and exterior of said housing during sterilization.

Claim 18

An acupuncture needle and needle guide assembly comprising: a needle, an elongated handle having a first axial portion secured to one end of said needle, an open ended tubular housing having a first portion with a tapered inner bore which is dimensioned to frictionally engage said first portion of said handle and a second elongated portion adjacent said first bore portion and dimensional to enclose said needle therein, first means for manually, slidably displacing said handle in a direction toward said second portion of said housing, at least one tubular end cap covering an end of said tubular housing and, fluid passage means intermediate said at least one tubular end cap and said housing for enabling air to communicate between the interior and exterior of said housing during sterilization.
