진공채혈관Vacuum vessel

본 발명은 진공채혈관에 관한 것이다.The present invention relates to a vacuum blood vessel.

보다 상세하게는 사용전의 감압상태의 경시에 의한 변화, 즉 보관중에 변화가 적은 진공채혈관에 관한 것이다.More specifically, the present invention relates to a vacuum blood vessel with little change during decompression before use, that is, during storage.

(종래의 기술)(Conventional technology)

진공채혈관은 생화학검사, 혈청학검사, 혈액학검사, 혈당측정, 혈액응고검사, 혈침검사, 세균학검사등에 사용되어, 개구부를 가지는 유저관에 고무전을 부착한 것으로 이루어지고, 사용전에는 상기 유저관의 내부는 감압상태로 되어 있어서, 그 정도는 필요한 만큼의 혈액량(2∼20ml)을 채혈할 수 있도록 적당한 감압상태로 유지되어 있다.Vacuum blood vessels are used for biochemistry, serology, hematology, blood glucose measurement, blood coagulation, blood acupuncture, bacteriology, etc., and a rubber tube is attached to a user tube having an opening. The inside is in a depressurized state, and the degree is kept in a depressurized state so that blood can be collected as much as necessary (2 to 20 ml).

종래부터 상기 유저관의 소재는 유리이나, 유리는 취급중이나 고속원심 분리조작에 있어서 파손하기 쉽기때문에, 최근에는 이것이 합성수지로 대체되고 있다.Background Art [0002] Conventionally, the material of the user tube is glass, but glass is easily damaged during handling and high speed centrifugal separation operation. In recent years, this has been replaced by synthetic resin.

진공채혈관용 합성수지는 폴리에스테르·폴리에틸렌·폴리프로필렌 등에서 선택된다.The synthetic resin for vacuum blood vessels is selected from polyester, polyethylene, polypropylene, and the like.

합성수지제 진공채혈관은 유리제 진공채혈관보다도 가스파리어성에 있어서는 뒤떨어진다. 그때문에 보관중은 진공채혈관을 진공포장으로 하여 놓든지 포장내부에 특정의 가스를 함유시키든가, 포장재료의 검토등이 이루어졌다.Synthetic resin vacuum tubes are inferior in gas fly properties to glass vacuum tubes. For this reason, during the storage, the vacuum collection tube was vacuum packed, a specific gas was contained in the packaging, and the packaging materials were examined.

본 발명은 가스파리어성에 있어서 우수한 합성수지제 진공채혈관을 제공하는 것이 목적이고, 본 발명에 의하면, 채혈전의 진공채혈관내부의 감압상태가 장기간에 결쳐서 유지할 수 있게 된다.An object of the present invention is to provide a vacuum resin tube made of a synthetic resin excellent in gas fly properties, and according to the present invention, it is possible to maintain a decompressed state inside a vacuum blood vessel before collection of blood for a long time.

본 발명에 있어서 천이금속은 염의 헝태로 사용하고, 초산코발트·나프텐산 코발트·스테아린산코발트·니켈아세틸아세트네이트·염화니켈·염화로듐 등이 있다.In the present invention, the transition metal is used as a salt, and includes cobalt acetate, cobalt naphthenate, cobalt stearate, nickel acetylacetonate, nickel chloride, rhodium chloride, and the like.

본 발명에 있어서 유저관체의 소재가 폴리에틸렌테레프탈레이트와 폴리 m-크실렌아디퍼미드, 천이금속의 염으로 된 혼합물이나, 이 혼합은 성형공정에 있어서 사입시 또는 그때까지 양원료를 혼합하여 두면 좋다.In the present invention, the material of the user tube is a mixture of polyethylene terephthalate, polym-xyleneadipamide, and a transition metal salt, and the mixing may be performed by mixing both raw materials at the time of insertion or until the forming step.

폴리 m-크실렌아디퍼미드를 혼합하여 성형함으로써 제품에 노르스름한 흔적이 생기는 일도 있다.A yellowish trace may arise in a product by mixing and shape | molding polym-xylene adipamide.

조성을 잘 균형시킴으로서 이 노르스름한 흔적을 잘 지울수가 있다. 이 노르스름한 흔적은 청색 또는 자색계통의 안료를 0∼3% 첨가하여 지우는 것도 가능하다. 이 청색 또는 자색 계통의 안료로서는 청색 1호(CI42090), 청색 2호(CI 73015), 청색 201호(CI 73000), 청색 202호(CI 42052), 청색 203호(Cl42052), 청색204호(CI 69825), 청색 403호, 자색 201호(CI 60725)등이 사용된다.By balancing the composition, this yellowish trace can be removed.

본 발명에 있어서 범용의 폴리에스테르에 폴리 m-크실렌아디퍼미드를 혼합하여, 천이금속임을 함유시키는 것은 가스파리어성의 우수한 유저관체를 얻는 동시에 산소를 흡수시키기 위함이며, 천이금속염이 이 작용을 촉진시키는 촉매로 된다고 생각이 된다.In the present invention, the poly-m-xylene adipamide is mixed with a general-purpose polyester to contain a transition metal in order to obtain an excellent gas pipe-like user body and to absorb oxygen, and the transition metal salt promotes this action. It is thought that it becomes a catalyst to make.

가스파리어성에 있어서 우수한 본 발명의 합성수지제 진공채혈관은 이와같이 산소를 흡수시켜서, 채혈전의 진공채혈관 내부의 감압상태가 장기간에 걸쳐서 유지되게 된다.The synthetic resin vacuum collection tube of the present invention excellent in gas fly properties absorbs oxygen in this way, and the decompression state inside the vacuum collection tube before collection is maintained for a long time.

When the poly m-xylene adipamide is more than this limit, the transparency becomes poor and the tube material cost becomes expensive.

또 이 한정치보다도 적게 되면, 산소흡수성이 떨어지게 된다.If the amount is smaller than this limit value, the oxygen absorbency is deteriorated.

본 발명에 있어서 천이금속을 1∼100ppm 함유시킬 필요가 있다. 천이금속임이 이 한정치보다도 많게 되면, 관체가 착색하여 투명성이 나쁘게 되며, 또한 관체원료비가 고가의 것이 된다.In the present invention, it is necessary to contain 1 to 100 ppm of the transition metal. If the transition metal is more than this limit, the tubular body becomes colored and the transparency becomes poor, and the tubular raw material cost becomes expensive.

또 이 한정치보다도 적게 되면, 산소흡수성을 촉진하는 촉매작용이 떨어지게 된다.If the amount is less than this limit, the catalytic action for promoting oxygen absorption is deteriorated.

본 발명에 있어서 유저관체용 고분자는 막영향을 주지 않는 첨가제라면 물론 그것을 함유하여도 좋다. 예컨대 산화방지제, 자외선차단제, 압출용 조제, 그의 중합체 개선용 첨가제 등이당.In the present invention, the polymer for the user tube may contain the additive as long as it is an additive that does not affect the film.
