Description

1
Изобретение относитс  к медицинской технике .
Существует р д приборов дл  проведени  диализа. Они содержат диализатор с полупроницаемой мембраной, устройство дл  приготовлени , перемешивани  и нагревани  диализирующего раствора.
Недостатком известных устройств  вл етс  то, что при длительном проведении диализа диализируема  жидкость подвергаетс  интенсивному бактериальному поражению
Дл  уменьшени  роста бактерий в диализируемой среде и уменьшени  таким образом возможности ее бактериального заражени  предлагаемое устройство снабжено приспособлением дл  перемешивани  и охлаждени  диализируемой жидкости, причем приспособление дл  охлаждени  установлено с одной стороны полупроницаемой мембраны, а приспособление дл  нагревани  - с другой.
На фиг. 1 схематически изображено описываемое устройство; на фиг. 2 - температурна  диаграмма в диализаторе.
Диализатор 1 разделен полупроницаемой мембраной 2 на две полости. К одной полости через 1магистрали 3 и 4 подключено приспособление 5 дл  перемешивани  и охлаладени  диализируемой среды, а к другой полости через магистрали 6 и 7 подключено приспособление 8, дл  пepe eшивaни  и нагревани  диализируемой среды.
Устройство работает следующим образом. Стерильна  диализируема  среда, например
водна  смесь из размолотых эмбриональных и плацентарных компонентов, перемешиваетс  и охлаждаетс  в приспособлении 5 до температуры ниже 4°С. По магистрал м 3 и 4 она подаетс  в одну полость диализатора и
возвращаетс  обратно. В другой полости диализатора находитс  стерильна  диализируема  жидкость, котора  по магистрал м 6 и 7 циркулирует в приспособлении 8. Здесь она перемешиваетс  и нагреваетс  до 25°С. Получаетс  указанное па фиг. 2 изменение температуры с резким температурным перепадом в области полупроницаемой мембраны 2. Область , граничаща  с мембраной 2, нагреваетс  до температуры 10°С. Это вызывает высокое броуновское молекул рное движение, необходимое дл  быстрого диализа.
Предмет изобретени 
25
Устройство дл  проведени  диализа, содерл ащее диализатор с полупроницаемой мембраной , приспособление дл  перемешивани  30 и нагревани  диализируемой жидкости, о тличающеес  тем, что, с целью уменьшени  биологического заражени  диализируемой жидкости, оно снабжено приспособлением дл  перемешивани  и охлаждени  диализнруемой
жидкости, причем приспособление дл  охлаждени  установлено с одной стороны полупроницаемой мембраны, а приспособление дл  нагревани  - с другой.
