Description
본 발명은 혈액채혈 및 보관용이나 생리식염수 보존에 사용되는 합성수지제 의료용 튜브의 제조방법에 관한 것이다.The present invention relates to a method for producing a synthetic resin medical tube used for blood collection and storage or physiological saline preservation.
이와 같은 의료용 튜브를 제조하기 위한 합성수지제 시트는 카렌다 방법에 의해 제조된 시트나 T다이스에 의해 제조된 시트 및 원형다이스에 의해 제조된 시트를 이용할 수 있으나 카렌다 방법에 의한 시트제조나 T다이스 공정에 의한 시트제조는 설비가 대형이어서 무진관리가 어렵고 핀홀 생성률이 많으며 튜브상으로 재접합하여야 하는 결점이 있어 의료용 튜브는 통상 원형다이스에 의해 제조하는 것이 보통이다.Synthetic resin sheet for manufacturing such a medical tube may be used a sheet produced by the calendar method or a sheet manufactured by the T dice and a sheet manufactured by the circular dice, but in the sheet manufacturing or T dice process by the calendar method Due to the large size of the equipment, it is difficult to manage dust-free, have a high rate of pinhole formation, and have defects that need to be rejoined on a tube. Thus, medical tubes are usually manufactured by circular dice.
그런데 원형 다이스에 의해 튜브를 제저하는 경우 설비투자액을 줄일 수 있고 시트상튜브로 제조되므로 시트를 원통형 튜브로 만들기 위한 별도의 공정이 필요치 아니하며, 튜브 내부가 노출되지 아니하므로 먼지등 이물질로부터 보호될 수 있는 등 장점이 있으나 튜브 내면의 점착성으로 인해 튜브가 납작하게 붙어버리므로서 튜브의 일단을 밀봉하고 타단에 호오스를 결합하는 등의 가공작업이 곤란한 결점이 있고, 핀홀의 생성으로 인하여 보존물이 외부로 누출된다던지 바이러스 등의 감염을 일으킬 염려가 있고 투습성으로 인하여 수분이 증발되어 내용물의 조성이 달라져 의료상의 문제가 발생할 염려가 있었다.However, if the tube is made by the circular die, the capital investment can be reduced, and since it is made of a sheet-shaped tube, a separate process for making the sheet into a cylindrical tube is not required. Although it has advantages such as the adhesiveness of the inner surface of the tube, the tube sticks flat and seals one end of the tube and couples the hose to the other end. There is a risk of leaking to the outside or causing an infection, such as a virus, and moisture caused by the moisture permeability evaporated to change the composition of the contents there was a risk of medical problems.
그리하여 튜브를 2중이상의 다층으로 형성시키므로서 핀홀을 폐색시키며 튜브 내층의 점착성을 제거토록 한다던지, 튜브 내면에 실리콘을 도포하거나, 튜브 내면에 세로무늬를 형성시켜 내면벽끼리의 점착과 누출을 방지한 튜브가 개발되기에 이르렀으나 이와 같이 실리콘을 도포한다던지 내면에 세로무늬를 형성시키는 것을 불편하고 또 이러한 방법으로는 핀홀을 제거하고 투습도를 개선하기가 곤란하였다.Thus, the tube is formed into a multilayer of two or more layers, so that pinholes are blocked and adhesiveness of the inner layer of the tube is removed, silicon is applied to the inner surface of the tube, or vertical patterns are formed on the inner surface of the tube to prevent adhesion and leakage between inner walls. Although a tube has been developed, it is inconvenient to apply silicon or to form a vertical pattern on the inner surface, and it is difficult to remove pinholes and improve moisture permeability in this way.
이에 본 발명은 복층성형용 원형다이스를 이용하여 두께 0.3-0.4mm 둘레 24-60cm의 복층 원통형시트를 제조하고 이를 의료용 용기로 사용케 하므로서 핀홀을 폐색시키고 투습도를 낮춰 용기내용물의 수분증발을 억제하였으며, 이에서 나아가 본 발명은 복층으로 형성시키는 원통형시트의 내층을 고용융조성물(Gelation)로 형성시키므로서 내외층을 외층 압축성형 온도조건으로 압출성형시키면 내층은 압출성형온도가 낮아 덜 용융(Gelation)되어 다소성형부족현상이 일어나게 되고 따라서 내부층 표면에 미세한 요철부(Embossing)가 형성하게 하였다. 이와 같이 내부에 요철부가 형성된 원통형 시트는 그 내면에 서로 붙지 아니하여 내면의 점착으로 인한 여러 가지 불편을 해소할 수 있다.Therefore, the present invention manufactured a multilayer cylindrical sheet having a thickness of 0.3-0.4mm and 24-60cm using a double-layered circular die and using it as a medical container, thereby blocking pinholes and lowering the moisture permeability to suppress moisture evaporation of the container contents. In addition, the present invention further forms the inner layer of the cylindrical sheet to be formed into a multi-layer melt-molded composition (Gelation), while the inner and outer layers are extruded under the outer layer compression molding temperature conditions, the inner layer is less melting (Gelation) because the extrusion molding temperature is lower As a result, some molding shortage was caused, and thus fine embossing was formed on the inner layer surface. As such, the cylindrical sheet having the uneven portion formed therein may not adhere to each other on its inner surface, thereby eliminating various inconveniences caused by the inner surface of the cylindrical sheet.
복층으로 된 원통형 시트의 내층을 외층에 비하여 고용융조성물로 형성시킴에 있어서는, 외층을 일반적인 수지조성물로 형성시키고 내층은 이와 같은 일반적인 수지조성물에 비하여 다소 가공온도가 높아지도록 외층부 조성물에 비하여 가소제를 약간 적게 혼합하거나 주원료인 수지의 중합도를 크게 하여 형성시키거나 혹은 니트릴고무(Nytril Rubber)를 혼합시키는 수단이 실시될 수 있으며, 반대로 외층부 조성물에 가소제 함량을 증가시켜 내층 조성물의 용융온도에 비하여 외층의 용융온도가 낮도록 하는 수단이 실시될 수 있다.In forming the inner layer of the multi-layered cylindrical sheet into a solid solution composition as compared with the outer layer, the outer layer is formed of a general resin composition and the inner layer has a plasticizer compared to the outer layer composition so that the processing temperature is somewhat higher than that of the general resin composition. It may be formed by mixing a little less or by increasing the polymerization degree of the main material resin or by mixing nitrile rubber.In contrast, by increasing the plasticizer content in the outer layer composition, the outer layer is compared with the melting temperature of the inner layer composition. Means may be implemented to lower the melting temperature of the.
