Definitions

  • the present invention relates to a filter cap for a syringe, and more particularly, to provide a filter and a housing to protect a needle, and to allow foreign substances such as fine glass chips, which are generated when the injection liquid glass ampoule is broken, get into the syringe.
  • the present invention relates to a filter cap for a syringe which prevents foreign substances from being injected into the human body to prevent injection, filling the injection liquid without exposing the needle to the outside, and preventing a safety accident that may be caused by a needle stick when the needle is replaced.
  • Injection glass ampoules are used to break the neck, so fine glass fragments are mixed into the injection solution. Fine pieces of glass are inhaled and filled into the syringe like injection, and thus are injected into the human body.
  • the medical community has raised the possibility that minute glass fragments generated when the glass ampoule is broken and opened can be injected into the human body through a needle, causing blood clots to cause fatal diseases such as myocardial infarction and stroke.
  • the KFDA research report also raised the possibility that glass fragments mixed with the injection of glass ampoules can be injected into the body through intravenous injection, causing pathological changes such as inflammatory reactions and granuloma formation in organs such as lungs, liver and spleen.
  • the Korea Food and Drug Administration's 2004 research report pointed out that since human lung capillary diameter is 10 ⁇ m, insoluble foreign substances such as glass fragments larger than this may cause serious diseases such as pulmonary embolism.
  • the present invention is to solve the problems of the conventional filter cap for syringes as described above, the purpose is to reduce the number of molds required for production and simple structure than the conventional, the defect rate in injection production is small, needle In the process of combining with the needle does not cause damage, it provides a filter cap for the hub-contact syringe corresponding to the needle of various outer diameters.
  • Filter cap for hub-adhesive syringe for achieving the above object is a filter attached to the inside of the housing by melt adhesion, needle fixed hub adhesion protrusion, needle to close contact with the needle fixing hub to form a negative pressure in the housing It is characterized by a ramp formed in the housing so as to be inserted smoothly.
  • the filter cap for the hub-adherent syringe of the present invention has a narrow inner diameter in place of the needle fixing hub-adhesive protrusion instead of the needle-adhesive path, so that the number of molds is reduced and the structure is simpler than the prior art.
  • the defect rate is small in the injection production, the needle does not damage the needle during the bonding process, and has the advantage that can cope with the needle of various outer diameters.

  • the filter 701 is fixed to the fusion bonding between the injection liquid inlet 704 and the needle insertion path 705 and the capillary diameter of 10 ⁇ m because of the critical significance for the filtration of glass fragments smaller than that Therefore, the filter 701 preferably has a transmittance of 10 ⁇ m or less, and in the preferred embodiment of the present invention, a filter having a transmittance of 5 ⁇ m or less is used.
  • the filter 701 may be provided through various materials that are chemically stable and can be melt-bonded without reacting with the injection liquid.
  • the ampoule insertion tube 702 is a part to be inserted into the ampoule 8, so the general inner diameter of the opening of the ampoule 8 is 4 mm to 10 mm, so it should have an outer diameter of less than that and an outer diameter of 3 mm or less to prevent contact contamination. This is preferred.
  • the injection solution inlet 704 is a portion in which the injection solution of the ampoule 8 is introduced, as shown in Figure 6 when the injection liquid filling is inclined because it is in close contact with the wall of the ampoule.
  • the filter 701 must have a protrusion to be melt-bonded, but the injection liquid inlet 704 has a diameter larger than the needle insertion path 705 so that the protrusion occurs, so that the injection liquid inlet 704 is larger than the needle insertion path.
  • the diameter should be large, and in the preferred embodiment of the present invention, a difference of about 0.8 mm is generated.

This solves the problem that the needle 6 is caught inside the housing during the automated manufacturing process and stops the operation of the automation facility, thereby facilitating automation for mass production.
  • the needle fixing hub insertion path 708 is a portion into which the needle fixing hub 5 is inserted, is connected to the inclined path 706 to penetrate the housing, and the needle fixing hub 5 is inserted thereinto. It penetrates to mate with the needle fixing hub (5).
  • the needle fixing hub insertion path 708 is formed in the needle fixed hub close contact 709 is in close contact with the needle fixing hub 5 to form a negative pressure inside the housing.
  • the needle fixing hub contact protrusion 709 may be formed in one or more rings (not shown), or may be formed in one or more spiral forms, as shown in Figures 4 and 5 Likewise, when used with the needle assembly coupled to the needle fixing hub contact protrusion 709, the sound pressure is better formed, but can also be used with the general needle assembly.
  • the housing is formed of a plastic material, but the housing may become tight or loose in the needle fixing hub 5 depending on the temperature due to the characteristics of the plastic that relaxation and shrinkage occur depending on the temperature.
  • the spiral shape the male and female are fastened by rotating, so the fastening force is consistent with the change in temperature.
  • the annular shape detachment is easy and quick instead of responding to temperature change like a spiral.
