Abstract

A patient'"'"'s skin puncturing device according to the present invention is built of a body (1) and of seated therein a pricking needle assembly (3) and of a push-button (5) arranged in the upper portion of the body (1). Between the push-button (5) and the pricking needle assembly (3) at least two driving springs (9) are arranged. The driving springs (9) are connected by upper ends with the push-button (5) provided with a pushing face (8). Between the body (1) and the pricking needle assembly (3) at least two return springs (30) are disposed, which are connected with the body (1). The pricking needle assembly (3) has a driving face (24) cooperating with the pushing face (8) of the push-button (5), and in the upper portion has wings (12) which upper surfaces cooperate with the driving springs (9) of the push-button (5) and which lower surfaces cooperate with the return springs (30), and has outer projections (17) cooperating with inner projections (18) with which the body (1) is provided.

Claims

1. A patient'"'"'s skin puncturing device built of a body (1) and of seated therein a pricking needle assembly (3) and of a push-button (5) arranged in the upper portion of the body (1), wherein between the push-button (5) and the pricking needle assembly (3) at least one driving spring (9) is arranged, and between the body (1) and the pricking needle assembly (3) at least one return spring (30) is arranged, characterised in that

it has at least two driving springs (9) connected by upper ends with the push-button (5) provided with a pushing face (8) and

it has at least two return springs (30) connected with the body (1), whereas

the pricking needle assembly (3) has

a driving face (24) cooperating with a pushing face (8) of the push-button (5),

wings (12) situated in the upper portion of the pricking needle assembly (3), whereas upper surfaces of the wings (12) cooperate with the driving springs (9) of the push-button (5) and lower surfaces of the wings (12) cooperate with the return springs (30), and

outer projections (17) cooperating with inner projections (18) with which the body (1) is provided.

2. The patient'"'"'s skin puncturing device according to claim 1, characterised in that in the body (1) at the level of the inner projections (18) are provided technological projections (21) which have a bigger height than a height of the inner projections (18) for protection the inner projections (18) from being damaged in the process of forming the moulded piece of the body (1).

3. The patient'"'"'s skin puncturing device according to claim 1 or 2, characterised in that the body (1) has an external flange (20) in which apertures (19) are provided for increasing an elasticity of the inner projections (18) of the body (1).

4. The patient'"'"'s skin puncturing device according to claim 1 or 2 or 3, characterised in that the driving springs (9) are integrally connected with the push-button (5) constituting one element formed in a technological process.

5. The patient'"'"'s skin puncturing device according to claim 1 or 2 or 3 or 4, characterised in that the return springs (30) are integrally connected with the body (1) constituting one element formed in a technological process.
