Abstract

The present invention provides a disposable protective film for a blood sampling device. The disposable protective film is assembled onto the pricker perforating end of the blood sampling device. The disposable protective film includes a film surface and a locating portion. The film surface is made of soft material that can be pierced by the pricker of the blood sampling device. The film surface is attached onto the end surface of the pricker perforating end of the blood sampling device. The locating portion, located laterally onto the film surface, is positioned onto the pricker perforating end of the blood sampling device. The disposable protective film provides a protective isolation for the blood sampling device and efficiently prevents adhesion of blood and dirt onto the blood sampling device.

Claims

1. A disposable protective film for a blood sampling device, said blood sampling device having a pricker, and a pricker perforating end with an end surface, a puncture hole, and a circumferential portion, said disposable protective film being assembled on said pricker perforating end, said disposable protective film comprising:

a film surface, being pierced by said pricker and being attached onto said end surface of said pricker perforating end of said blood sampling device; and

a locating portion, located laterally onto a preset position of said film surface said locating portion being positioned onto said pricker perforating end of the blood sampling device.

2. The film defined in claim 1, wherein said film surface is cup-shaped and attached onto said end surface and said circumferential portion of said pricker perforating end of said blood sampling device.

3. The film defined in claim 1, wherein said film surface is flexibly retracted.

4. The film defined in claim 1, wherein said locating portion is comprised of a solid ring body.

5. The film defined in claim 1, wherein said locating portion is comprised of a flexible ring body.

6. The film defined in claim 1, wherein the film surface and locating portion are comprised of flexible film, said film surface being flatly coupled with a jig with an interpolation hole, said film surface being aligned with said interpolation hole, said interpolation hole receiving said pricker perforating end of said blood sampling device, said film surface being attached onto said end surface of said pricker perforating end of the blood sampling device, said locating portion being attached onto said circumferential portion of said pricker perforating end.

7. The film defined in claim 1, wherein said film surface is provided with a pricker punch hole.

8. The film defined in claim 1, wherein said locating portion is arranged around said film surface, and sleeved onto said circumferential portion of said pricker perforating end of said blood sampling device.

9. The film defined in claim 1, wherein said locating portion is arranged laterally onto said film surface and adhered securely onto said end surface or said circumferential portion or both.
