Definitions

  • the invention relates to a needle guard, in particular intended for a blood sampling needle, with an outer sleeve arranged around a needle with a tip, within which an inner sleeve surrounding the tip of the needle extends at least in regions.
  • a needle guard of the type described above is known (D E 27 33 670 AI). This needle protection is intended to prevent the tip from digging into the wall of the sheath when the needle is twisted, as a result of which plastic splinters can come loose from the wall. Such plastic splinters may stick to the needle tip. If the plastic splinter is inserted unnoticed into the body or into a blood vessel of a pereon, the person can suffer health damage.
  • the inner sheath is also intended to ensure that liquid cannot escape from the needle.
  • the outer sheath is of hollow cylindrical design with an opening above the needle tip.
  • the outer shell including the handle is z. B. manufactured by injection molding. After that the Inner sleeve produced in a special operation is inserted into the cylindrical opening and pushed over the tip of the needle. Then the opening of the outer shell is closed with a stopper which, for. B. is glued to the outer shell.
  • this needle guard is relatively complex. Since the outer and inner shells should be arranged concentrically, small manufacturing tolerances are required. In the event of production-related deviations from the tolerances, difficulties arise when assembling the parts.
  • the invention is based on the problem of developing a needle guard of the type described at the outset in such a way that the inner sleeve can be fitted precisely around the tip of the needle with as little effort as possible and can be arranged in a fixed position within the outer sleeve.
  • the needle guard should also be easy to manufacture and mountable on a needle.
  • the inner sleeve and the outer sleeve are parts manufactured in at least two-component injection molding and that the inner sleeve is secured in the axial direction of the needle by a positive and / or non-positive connection with the outer sleeve.
  • Two- or multi-component injection molding is understood to mean that the needle guard, which is composed of the inner and outer shells, is produced in one workflow in a two- or multiple injection process.
  • connection between the inner and outer cover according to the invention has the advantage that the relative position of the inner and outer cover is not changed by external stresses during storage or transport of the needle guard.
  • the inner shell can not due to external stresses such. B. temperature changes in connection with external forces, change their position within the outer shell. Rather, the desired centering of the inner shell remains within the outer shell, so that piercing of the inner shell is thus excluded. There is no danger that the needle tip will penetrate to the inner wall of the outer sleeve and thus pick up particles.
  • the needle guard is absolutely leak-proof and manufactured using the multi-component injection molding process.
  • the outer shell which is sprayed around the inner shell after it has hardened, is arranged on the inner shell with virtually no play and encloses it. Assembly work is unnecessary because of the production in one operation.
  • the advantage of multi-component spraying is that external and the inner shell always have the desired wall thickness.
  • the inner shell is fused to the outer shell at least in some areas. This is guaranteed by the choice of materials for the outer and inner shell and the temperatures applied during injection molding.
  • Suitable materials as such are suitable plastics or plastics-like materials, in particular based on rubber.
  • the materials can optionally also be filled, i. H. be glass fiber and / or carbon fiber reinforced.
  • a magnifying effect can take place in order to be able to check the position and / or condition of the needle cut from the outside.
  • the inner sleeve at its end facing away from the needle tip has an end surface inclined towards the longitudinal axis of the needle, which facilitates insertion of the needle.
  • the inner surface of the inner shell can also be aligned with the free inner surface of the outer shell.
  • the inner shell can optionally protrude above the outer shell.
  • the former can be provided with projections which are surrounded by the outer shell.
  • projections which are surrounded by the outer shell.
  • only one protrusion which may be circumferential, can also be provided.
  • the outer cover is preferably rotated, as a result of which the separation occurs at the predetermined breaking point adjacent to the handle. This rotation does not affect the inner shell.
  • the outer shell is pulled off axially. The inner shell will be taken along. This will expose the needle.
  • FIG. 1 shows a cannula with needle guard in longitudinal section in an enlarged view
  • FIG. 2 shows a front part of a second embodiment of a needle guard with a needle in longitudinal section
  • FIG. 3 shows a front part of a third embodiment of a needle guard with a needle in longitudinal section
  • Fig. 15 is a principle division regarding the assembly of the needle guard on a needle.
  • a needle guard (10) for a blood sampling or infusion needle (12) contains an outer cover or protective cap (14) made of plastic, which is integrally connected to a handle (18) by a thin, annular predetermined breaking point (16). Ribs (20) extend from the outer sheath (14) and facilitate the removal of the outer sheath (14) of the needle (12).
  • the handle (18). has a recess (22) which is open towards the rear and into which the end (26) of the needle (12) remote from the needle tip (24) projects.
  • a blood collection tube not shown, is pushed onto the end (26) and is connected to a blood bag of a conventional type.
  • FIG. 1 there is an inner shell (28) inside the outer shell (14) which, like the outer shell (14), has a closed end (30).
  • the inner sleeve (28) surrounds the needle tip (24) and the area of the needle (12) adjoining the needle tip (24).
  • At least the inner shell (28) and the outer shell (14) are produced in a two-component injection molding process.
  • the handle (18) is preferably also produced at the same time.
  • a two- or multi-component injection molding process can be used.
  • the inner shell (28) is first produced.
  • the outer shell (14) is then optionally formed with the handle (18), the latter also being able to be produced in a third step.
  • a double mold with different cavities is preferably used to produce the needle guard (10).
  • the needle guard (10) is created in two work cycles.
  • FIG. 2 is intended to clarify. Intimate connections and positive locking can also be present at the same time.
  • the inner shell (28) By manufacturing in the two-component injection molding process, in which the parts available after one work cycle are used as cores for the next work cycle, a precise centering between the inner shell (28) and outer shell (14) is achieved. Furthermore, the inner and outer shells have uniform wall thicknesses. The inner shell (28) is practically without tolerance, d. H. arranged without play in the outer shell (14). In the case of the needle guard (10) produced in the two-component injection molding process, an assembly work step is saved since the needle guard (10) can already be removed from the injection mold.
  • the positive connection between the inner shell (28) and the outer shell (14) ensures that the relative position between the inner and outer shell, for. B. during storage or transportation of the needle guard (10) or during its assembly, does not change. It can therefore not happen that the ground needle tip pierces the inner sleeve (28). Consequently, the desired tightness is always guaranteed on the one hand and on the other hand it is ensured that no plastic particles are peeled off the outer shell wall. The latter causes the lumen to be free of particles.
  • the outer shell (14) To remove the outer shell (14), it is rotated relative to the handle (18). The connection between the outer shell (14) and the handle (18) is broken at the predetermined breaking point (16). The rotary movement is facilitated by the ribs (20), which form a larger contact surface for the hand. As illustrated in FIG. 1, the inner sleeve (28) has an end face (34) which is distant from the needle tip (24) and is chamfered. This is to facilitate the insertion of the needle (12) into the needle guard (10).
  • the wall thickness of the outer casing or protective cap (14) is constant over its length.
  • the inner shell (28) is deposited on the inner surface of the outer shell (14).
  • FIG. 2 shows a needle guard (35), in which the axial fixation and coaxial alignment of an inner sleeve (36) with an outer sleeve (38) is achieved in a different way than in FIG. 1.
  • the two-component injection molding process is also used in relation to the inner shell (36) and the outer shell (38).
  • the inner sleeve (36) surrounds at least the needle tip (24), i.e. H. the inner shell (36) is also cap-shaped.
  • a positive connection is provided to ensure that the inner casing (36) is clearly fixed in position within the outer casing (38). On the one hand, this is achieved in that the inner shell (36) is received by the outer shell (38).
  • the inner surface (40) of the inner shell (36) therefore merges flush with the inner surface (46) of the outer shell (38).
  • the end region (44) of the inner casing (36) can be wedge-shaped.
  • protrusions (39) and (41) can extend from the outer surface (37) of the inner shell (36), which corresponding recesses (43) and (45) of the outer shell (38) extend. In this way, there is a positive connection between the inner casing (36) and the outer casing (38), without an intimate connection being necessary.
  • FIG. 3 provides a needle guard (48), which is composed of an outer shell (50) and an inner shell (52), which have been positively connected to one another and have been produced in a two-component injection molding process.
  • projections (56) emanate from the inner casing (52) and are located within the outer casing (50) extend. These areas, which can be referred to simply as recess, have the reference symbol (58). It is not imperative - as is shown in the drawing - that the projections (56) protrude to the outer surface (60) of the outer shell (50).
  • the end region (62) of the inner shell (52) is chamfered and continues in a section (64) of the outer shell (50). It is hereby achieved that the wall thickness of the outer casing (50) outside the inner casing (52), that is to say in the area (66), is less than in the area of the inner casing (52).
  • FIGS. 4 to 13 show further variants of needle protection or protective cover arrangements, each of which is composed of an outer cover and an inner cover partially accommodated by it.
  • the outer and inner shell are manufactured using the two-component injection molding process.
  • the outer and inner shell can be connected either positively or non-positively. There is also a combination of these connection options.
  • the outer and inner sheaths can also have different colors so that certain cannulas can be identified.
  • the handle is also produced together with the protective covering in a multi-component injection molding process, it being possible for the handle to be formed with the outer shell in one manufacturing step. Of course, two steps can also be carried out.
  • At least one form-fitting connection takes place in that projections extend from the respective inner shell and extend within the outer shell.
  • an inner shell (68) has a projection (70) which is circumferentially arranged in its end region and is surrounded by the material of the outer shell (74).
  • the inner shell (68) is not completely absorbed by the outer shell (74). Rather, the outer sheath (68) projects with a section (76) over the outer sheath (74) without, however, leaving the features which characterize the invention in relation to the concentric arrangement with the longitudinal axis of the needle.
  • the projection (70) is circumferential.
  • the inner shell (68) can also be connected to the outer shell (74) in a type of toothing.
  • the inner wall of the inner sleeve (68) merges flush into the inner wall of the outer sleeve (74), ie that there is essentially no change in cross-section from the space accommodating the needle (not shown) 8 shows the open edge region (78) of an inner shell (80), which is preferably completely of an outer shell (82) is received, be expanded in a truncated cone shape. This ensures a safe insertion of a needle into the inner sleeve (80).
  • the inner casing (80) also has a preferably circumferential projection (84) which runs inside the outer casing material.
  • a corresponding conical geometry can also be found in the exemplary embodiment in FIG. 9.
  • the position of the corresponding inner shell (86) is clearly fixed by means of a laterally projecting projection (88) inside the outer shell (90).
  • the projection (88) specifies the shape of the corresponding recess in the outer casing (90), since the inner casing (86) is at the same time the mandrel of the injection molding tool when the outer casing (90) is formed.
  • FIGS. 5 and 6 differ essentially in that an inner shell (92) is completely (FIG. 5) or partially (FIG. 6) surrounded by an outer shell (94) and (96). This surrounding is preferably carried out in a form-fitting manner in that at least a region-wise fusion takes place between the inner shell (92) and the outer shell (94) or (96).
