Abstract

There is disclosed herein a hypodermic syringe which is disposable and intended to be non-reusable. The syringe includes a body and a protector case which slidably contains the body to uncover the needle of the syringe for use and to cover the same after use. The case and body incorporate a detent arrangement for holding the body within the protector case in respective first and second positions. The protector case can include a surface providing a data recording area.

Claims

1. A medical fixture for collecting, holding and transferring fluid, including a needle, a body, and a protector case, wherein said protector case has upper and lower surfaces thereon, and slidably contains said body, the improvement comprising

said protector case has on said lower surface thereof a data recording area, and

said body having finger gripping means on an upper surface projecting through said protector case for retracting said body within said protector case.

2. A medical fixture for collecting, holding and transferring fluid, including a needle, a body, and a protector case, wherein said protector case has upper and lower surfaces thereon, and slidably contains said body, the improvement comprising

said protector case has on said lower surface thereof a data recording area, and

wherein said protector case and said body mutually incorporate first and second detent means for holding said body within said protector case, in first and second positions, respectively.

4. The syringe of claim 2 or 3, wherein said case has two side members, each having thereon at one end inwardly extending fingers respectively engaging two shaped grooves on said body, and forming detents thereby.

3. A medical fixture for collecting, holding and transferring fluid, including a needle, a body, and a protector case, wherein said protector case has upper and lower surfaces thereon, and slidably contains said body, the improvement comprising

said protector case has on said lower surface thereof a data recording area, and

wherein said body has finger gripping means on an upper surface thereof projecting through said protector case for retracting said body within said protector case, and

said protector case and said body mutually incorporate first and second detent means for holding said body within said protector case, in first and second positions, respectively.

5. A medical device for collecting, holding or transferring fluid, including a body adapted to receive a needle, and a protector case, wherein said protector case has upper and lower surfaces thereon, and slidably contains said body, the improvement comprising

said protector case has on one of said lower or upper surfaces a data recording area, and

wherein said body has a finger grip on one of the upper or lower surfaces projecting through said protector case for retracting said body within said protector case.

6. A medical device for collecting, holding or transferring fluid, including a body adapted to receive a needle, and a protector case, wherein said protector case has upper and lower surfaces thereon, and slidably contains said body, the improvement comprising

said protector case has on one of said lower or upper surfaces thereon a data recording area, and

wherein said protector case and said body mutually incorporate first and second detent means for holding said body within said protector case, in first and second positions, respectively.
