Description
생활의 다양화로 우리 주위에서 여려가지 병이 나돌고 있다. 따라서 병원에서 발생하는 의료폐기물도 다양하다. 또한 여기에 묻어 나오는 병원균도 다양하여 전염성이 강한 병원균이 오염되어 사회적 물의를 일으키는 경우도 있다.Due to the diversification of life, there are many diseases around us. Therefore, medical waste generated in hospitals also varies. In addition, there are a variety of pathogens buried in this way, the infectious pathogens are contaminated, causing social controversy.
본 특허에서는 이와 같은 의료폐기물 특히 액체성분을 위생적으로 처리하는 방법과 장치를 설명하고자 한다. 우선 의료폐기물중 액체성분인 피, 체액 또는 의약품류 등이 수술, 치료시 다량 발생하게 되는데 여기에는 많은 균들이 함유되어 다른 사람에게 전염되는 사회적 문제를 일으키는 경우가 종종 발생하고 있다.This patent describes a method and apparatus for sanitizing such medical waste, particularly liquid components. First of all, medical wastes, such as blood, body fluids, or medicines, are generated in large quantities during surgery and treatment, which often contain many bacteria and cause social problems that are transmitted to others.
그래서 시판되는 의료폐액 위생 처리장치를 보면 의료폐액부위(장소)로부터 흡입할 수 있는 흡입관이 있고, 흡입된 의료폐액을 저장할 수 있는 진공흡입병에 흡입되어져 들어가면 고흡수성(친수성) 고분자에 의해 Gel化된다. 여기에는 살균제가 함유되어 있어 의료폐액중의 균들이 살균되어진다.Therefore, the commercially available medical waste hygiene treatment device has a suction tube that can be inhaled from the medical waste area (place), and is drawn into a vacuum suction bottle that can store the inhaled medical waste fluid, and then gelated by a superabsorbent (hydrophilic) polymer. do. It contains fungicides, which kills germs in medical waste.
본 특허에서는 흡입되어진 의료폐액중에는 피, 체액 또는 의약품 및 의료제료 중 친수성 물질과 소수성 물질로 이루어 졌는데 시판되는 것에는 친수성 물질만 흡수하는 고흡수성 고분자를 사용하였으므로 친수성은 의료폐액은 응고되지 않고 흘러내려 여기에 함유된 세균에 의해 오염되는 경우가 있다. 그래서 본 연구에서는 친수성ㆍ소수성 의료폐액 모두 흡수 응고시킬 수 있는 특수응고제를 개발하여 사용하였다.In this patent, the inhaled medical waste consists of hydrophilic and hydrophobic substances in blood, body fluids, or medicines and pharmaceuticals. The commercially available super absorbent polymer that absorbs only hydrophilic substances is used, so that the hydrophilic fluid flows without coagulation. It may be contaminated by the bacteria contained therein. Therefore, this study developed and used special coagulant to absorb and coagulate both hydrophilic and hydrophobic medical waste fluid.
또한 시판된 의료폐액 위생처리 장치(ISOLYSER,1200, USA)에서는 의료폐액이 흡입관을 통해 곧바로 진공흡입용병에 보관되어지는데 이 흡입용병은 다량의 의료폐액을 보관하여야 하므로 크고 여러 성분의 의료폐액이 혼합되어짐과 동시에 곧바로 응고제에 의해 응고되어 지므로 의료페액의 상태를 관찰 조사해야 하는 의료인으로로서는 어려움이 있다. 그래서 본 특허에서는 흡입진공병 앞쪽에 100㎖정도의 투명한 Plastic병 또는 Glass병을 연결시켜 환자로부터 흡입되어진 의료폐액의 상태를 관찰조사한후 진공흡입관을 통해 흡입진공병으로 보관시키는 장치를 발명하였다(도면 1 참조).In addition, commercially available medical waste treatment equipment (ISOLYSER, 1200, USA), medical waste is stored in a vacuum suction bottle directly through a suction tube, and since this suction bottle must store a large amount of medical waste liquid, a large amount of various medical waste liquids are mixed and immediately solidified by a coagulant. It is difficult for a medical person to observe and examine the state of the lung fluid. Thus, the present invention invented a device for connecting a 100 ml transparent plastic bottle or glass bottle in front of an inhalation vacuum bottle to observe the state of medical waste fluid inhaled from the patient, and then storing the inhalation vacuum bottle through a vacuum suction tube. 1).
그렇게 함므로해서 환자로부터 발생하는 의료폐액의 상태를 좀더 관찰 조사해 환자치료의 정보를 얻을 수 있을 뿐아니라, 만약 진공 발생 발생원에서 진공흡입력이 떨어지거나 감소되었을 때 진공흡입병에 보관된 의료폐액이 역류할 수 있게되는데 이 보조병을 설치하므로 해서 역류하여 오염되는 것을 지연 시킬 수 있는 장점을 갖고 있다.By doing so, the medical waste fluid generated from the patient can be further observed and examined to obtain patient treatment information. If the vacuum suction input is decreased or decreased at the source of the vacuum generation, the medical waste fluid stored in the vacuum bottle is refluxed. By installing this auxiliary bottle, it has the advantage of delaying the contamination due to the backflow.
좀더 자세히 언급하면 수술이나 진료과정에서 발생하는 의료폐액에서는 친수성 물질과 소수성 물질이 있는데 이 모두를 응고 Gel化시킬 수 있는 응고제로서 고흡수성 고분자로서 전분-아크릴산 나트륨 공중합체 또는 아크릴산계통의 고흡수성 고분자와 소수성 물질을 흡수할 수 있는 미강(쌀겨)을 6:4에서 9:1까지 혼합하여 사용할 수 있으며, 최적조건으로는 8:2의 比로 사용하였다. 또한 여기에 크레졸 같은 살균제를 함유시켜 의료폐기물이 응고됨과 동시에 함유하고 있는 병원균들이 곧바로 살균되도록 하였다. 이때 살균제를 응고제와 혼합비율로서 전체 중량의 30%에서 5%까지 변화시켜가며 사용하였다. 최적조건은 전체 중량의 10%로 한 것이 좋은 결과를 가져다주었다. 이렇게 하여 감염성 있는 의료폐기물을 손쉽게 처리하는 방법을 고안해 낼 수 있었다.More specifically, there are hydrophilic substances and hydrophobic substances in medical wastes generated during surgery or medical procedures. Both of them are coagulants that can coagulate and gelate the superabsorbent polymer. Rice bran (rice bran), which can absorb hydrophobic substances, can be mixed from 6: 4 to 9: 1, and used as an optimum ratio of 8: 2. In addition, it contains a bactericide such as cresol, which coagulates medical waste and sterilizes pathogens. At this time, the fungicide was used while changing the coagulant and mixing ratio from 30% to 5% of the total weight. Optimal conditions were good at 10% of the total weight. In this way, it was possible to devise an easy way to deal with infectious medical waste.
[실시 예 1]Example 1
고흡수성 고분자로서 전분-아크릴산 나트륨 그라프트 공중함체 가교제 분만 80%(중량대비)와 쌀겨(미강) 20%(중량대비)를 섞은 뒤 크레졸을 전체중량의 10%를 균일하게 흡착시킨다. 이 복합 고분자를 건조한 후 100mesh정도의 분말로 만들었다. 이와 같이 의료폐기물 흡착제를 만든 후 의료폐기물(액체)의 침출수의 이온농도에 따른 흡착효과를 보기 위해 물 80%(중량대비), 식용유 20%(중량대비)의 혼합액에 소금을 중량대비 0%, 1%, 2.5%, 5%를 넣어 배출수 중의 이온농도를 조절하여 제조하였다.As a super absorbent polymer, only 80% (by weight) of starch-sodium acrylate graft copolymer crosslinking agent is mixed with 20% (by weight) of rice bran (by weight), and then cresol is uniformly adsorbed by 10% of the total weight. The composite polymer was dried to a powder of about 100 mesh. In this way, after making medical waste adsorbent, in order to see the adsorption effect according to the ion concentration of leachate of medical waste (liquid), add 80% salt by weight and 20% cooking oil by weight to salt, 1%, 2.5%, 5% was added to prepare the ion concentration in the effluent.
유리컵에 소량의 의료폐액의 흡착제를 넣은 후 임의 제조한 의료폐액을 컵속에 넣어 5분후 이 컵을 거꾸로 하여 흡착제에 흡수된 인공 의료폐액이 밑으로 흘러내리지 않을 때까지 하여 최대 흡착량을 구하였다. 그 결과 염을 첨가하지 않은 것의 최대 흡착량은 흡착제 自重(중량대비)의 330배를 흡착하였다.After placing a small amount of medical waste adsorbent into the glass cup, a randomly prepared medical waste liquid was placed in the cup, and after 5 minutes, the cup was inverted and the maximum amount of adsorption was obtained until the artificial medical waste absorbed by the adsorbent did not flow down. . As a result, the maximum amount of adsorption without adding salt adsorbed 330 times the weight of the adsorbent.
그러나 1% 소금을 함유시킨 인공 의료폐액의 경우 自重의 50배, 2.5%의 소금을 함유시킨 경우 自重의 45배, 5% 소금을 함유시킨 경우 自重의 34배를 흡착할 수 있다는 결과를 얻었다.However, in the case of artificial waste containing 1% salt, 50 times of self weight, 45 times of self weight when 2.5% salt was contained, and 34 times of self weight when 5% salt was included were obtained.
실제 돼지 피를 가지고 침전시킨 후 혈청성분을 가지고 흡착시킨 결과 自重의 43배를 흡수하였다.After precipitating with the actual pig blood and absorbed with the serum component absorbed 43 times its own weight.
[시험 예 1][Test Example 1]
실시 예 1에서 실시 예 1의 고흡수성 고분자 대신 폴리 아크릴 타이프 고흡수성 고분자를 사용한 것을 제외하고는 실시 예 1과 타이프 고흡성 고분자를 사용한 것을 제외하고는 실시 예 1과 동일한 방법으로 실험하였다.In Example 1, except that the polyacrylic type superabsorbent polymer was used instead of the superabsorbent polymer of Example 1, the experiment was performed in the same manner as in Example 1, except that Example 1 and the type superabsorbent polymer were used.
그 결과 소금을 함유시키지 않은 인공 의료폐액의 경우 自重의 91배, 1% 염의 농도에서는 自重의 33배, 2.5% 염농도에서는 自重의 24배, 염농도 5% 인공 의료폐액에서는 自重의 17배를 흡착하는 결과를 보였다.As a result, it is adsorbed 91 times of self weight for artificial medical waste without salt, 33 times of self weight for 1% salt concentration, 24 times self weight for 2.5% salt concentration, and 17 times self weight for artificial salt 5% salt concentration. The results were shown.
[실시 예 2]Example 2
실시예 1에서 만들어진 의료배출폐액 흡착제에 살균제로서 크레졸 전체중량의 10%를 함유시키지 않은 흡착제에 실제 의료폐액을 흡착시킨후 각각 소량의 흡착제를 Sampling하여 10㎖의 살균된 중류수에 흡착 분산시킨 후 제조된 YM, E, N배지에 각각 1㎖씩 도포시켜 접종시킨 후 30℃ 배양기에서 48시간후 각각의 코로니수를 검토하였다.After adsorbing the actual medical waste to the adsorbent that did not contain 10% of the total weight of cresol as a disinfectant in the adsorbent made in Example 1, each small amount of adsorbent was sampled and dispersed in 10 ml of sterile middle water. 1 ml each of the prepared YM, E, and N medium was inoculated and inoculated, and then, after 48 hours in a 30 ° C. incubator, the number of colonies was examined.
그 결과 크레졸로 처리된 것에는 YM, E, N배지 모두 코로니를 형성하지 않았다. 반면 크레졸 처리안된 흡착제에서는 수백 개의 코로니를 발견할 수 있었다.As a result, all of the YM, E, and N medium did not form colonies in the cresol treatment. On the other hand, hundreds of colonies were found in the uncresolized adsorbent.
[실시 예 3]Example 3
실시 예 1에서 만든 의료폐액 흡착응고제와 시판하는 의료폐액 흡착응고제를 이용하여 소수성인 의료폐액의 모델로 병원에서 치료시 많이 사용하는 실리콘 오일(Silicon oil) 20%와 물 80%을 섞어만든 액체를 사용하여 흡착실험을 사용한 결과 실시 예 1에서 만든 흡착 응고제에서는 모두 흡착 응고되었다. 반면 시판되는 의료패액 흡착응고제는 친수성인 물 성분은 흡착되었으나 소수성인 oli 성분은 그대로 흘러내려 흡착 응고시키지 못한 결과를 가져왔다.A liquid made of a mixture of 20% silicone oil and 80% water, which is frequently used for treatment in hospitals, is a model of hydrophobic medical waste liquid using the medical waste liquid adsorption coagulant prepared in Example 1 and a commercially available medical waste liquid adsorption coagulant. As a result of using the adsorption experiment, all of the adsorption coagulants prepared in Example 1 were adsorption coagulation. On the other hand, commercially available medical fluid adsorption coagulants resulted in the adsorption coagulation of hydrophilic water components but the hydrophobic oli components as they flowed out.
[실시 예 4]Example 4
의료폐기물(액체)이 발생하는 부위(또는 장소)에서 진공으로 흡입 수거하는데 우선 흡입관이 있고 흡입된 폐액을 저장할 흡입 진공병이 있는데 흡입관과 흡입진공병 사이에 100㎖의 투명한 보조 진공흡입병을 설치하여 실제 의료폐기물(액체)을 흡입수거 하였다(도면 1 참조). 그리고 흡입 수거된 의료폐기물이 투명한 보조 진공흡입병에 흡입되어져 의료폐액을 관찰하기 편리하였다. 보조 진공흡입병에 있는 의료폐액은 계속된 진공흡입력에 의해 진공흡입병에 들어가 응집제와 반응하여 곧바로 Gel化 또는 固化되어 졌다.There is a suction tube and a suction vacuum bottle to store the sucked liquid.The 100 ml transparent auxiliary vacuum suction bottle is installed between the suction tube and the suction vacuum bottle at the place (or place) where medical waste (liquid) occurs. The actual medical waste (liquid) was collected by aspiration (see Figure 1). In addition, the collected medical waste was inhaled in a transparent auxiliary vacuum suction bottle, which was convenient to observe the medical waste liquid. The medical waste liquid in the auxiliary vacuum inhalation bottle immediately enters the vacuum inhalation bottle and reacts with the flocculant and gelates or denatures.
또한 진공펌프의 고장으로 진공흡입이 안돼 진공흡입병에 있는 의료폐액이 역류할 것을 대비하여 그 안전장치로 보조 진공 흡입병의 역할을 조사하기 위해 진공펌프의 동작을 멈추었다. 시판된 의료폐기물 수거장치에서는 역류가 시작되어 곧바로 흡입관 밖으로 역류되었다. 그러나 본 특허의 장치에서는 보조 진공 흡입병이 있어 진공흡입병에 있는 의료폐액이 보조 진공 흡입병에 머무는 시간이 있어 곧바로 역류를 알아볼 수 있어서 흡입관에 있는 흡입 스위치를 잠가 의료폐액이 흡입관을 통해 역류되어 밖으로 도출되는 것을 막을 수 있었다.In addition, the vacuum pump was stopped due to a failure of the vacuum pump, and in order to prevent backflow of the medical waste liquid in the vacuum suction bottle, the vacuum pump was stopped to investigate the role of the auxiliary vacuum suction bottle as a safety device. In commercial medical waste collection devices, backwash began and immediately flowed out of the suction line. However, in the device of this patent, there is an auxiliary vacuum suction bottle so that the medical waste liquid in the vacuum suction bottle stays in the auxiliary vacuum suction bottle so that the reverse flow can be recognized immediately. It could prevent being drawn out.
또한 진공흡입병의 밸브중 진공펌프로부터 흡입되는 밸브에 활성탄(또는 종이필터) 칼럼관을 설치한 결과 진공흡입병에 비산되어 있는 병원균이나 의료폐액 응고제의 분말이 진공흡입관을 통해 진공 펌프쪽으로 오염되는 것을 막을 수 있었다.In addition, the activated carbon (or paper filter) column tube is installed in the valve of the vacuum suction bottle to be sucked from the vacuum pump, so that the powder of pathogen or medical waste coagulant scattered in the vacuum suction bottle is contaminated toward the vacuum pump through the vacuum suction tube. Could be prevented.
