Description
Technical field
The utility model relates to the pipe connecting structure of bioreactor, relates in particular to a kind of aseptic fast connecting joint.
Background technique
In the process of applying biological reactor fermented and cultured cell, often need carry out operations such as fluid infusion, sampling, discharge opeing, results nutrient solution.When carrying out above operation all the essential nutrient solution that guarantees in the bioreactor thereby adopt jointing to carry out various liquid containers usually to be connected with the quick of pipeline between the reactor not by living contaminants, to reduce the probability of nutrient solution in the living contaminants reactor.
At present, the jointing of employing is mainly stainless joint and plastic joint, the catenation principle unanimity of two kinds of joints, just material difference.Usually, two butt joints of stainless joint and plastic joint are fixedlyed connected by jump ring, guarantee sealing by the rubber washer on the cutting graftage part.Because cost and the thermal conductivity of stainless joint, reasons such as flame calcination such as the plastic material alcoholic intolerance essence of plastic joint, two kinds of length of said joint are all shorter, pair of joint connects between 4-8cm, not easy to operate when carrying out the attended operation of flame calcinations such as alcohol at needs, and have burn dangerous.In addition, contain salt mostly in the drain composition, stainless steel is had corrosive action, and the stainless joint cost is higher.Though the plastic joint price is cheaper, not flame resistant calcination, the probability of pollution microbes increases in the connection procedure.
Summary of the invention
The purpose of this utility model aims to provide a kind of aseptic fast connecting joint.This aseptic fast connecting joint simple in structure need not to adopt seal washer can obtain extraordinary sealing effect in use.
The purpose of this utility model realizes by following technical measures: a kind of aseptic fast connecting joint, comprise first connecting tube and second connecting tube, described first connecting tube comprises carrier with port and the joint that is connected with flexible pipe of being used for that is positioned at the carrier tail end, described carrier has from tail end accepts the chamber to the taper that its port direction flaring forms, described second connecting tube comprises cutting graftage part with port and the joint that is connected with flexible pipe of being used for that is positioned at the cutting graftage part tail end, the front end of described cutting graftage part has tapered portion, and this tapered portion is adaptive to be plugged on described taper and to accept and form cone seal in the chamber.
The tapering of the tapered portion of chamber and cutting graftage part is accepted in the taper of carrier described in the utility model should be as far as possible little, preferred tapering control is in 5 degree, make the tapered portion internal diameter of cutting graftage part reach consistent with internal diameter of tube body, guarantee that fluid can freely flow suitablely, and make tapered portion and described taper accept the sealing effect that can reach best between the chamber, and can also be convenient to the dismounting of the two.
The utility model can also be done following improvement: the tail end of the carrier of described first connecting tube is provided with at least one pair of symmetrical grab, and described grab is arranged along the outer periphery of carrier tail end; The tail end of the described second connecting tube cutting graftage part is provided with the grab of at least one pair of symmetrical distribution, described grab distributes along the outer periphery of the tail end of connection-peg, grab on the described carrier is opposite with the direction of the grab on the cutting graftage part, be used for elastic cord and bundle to reinforce connection between first connecting tube and second connecting tube, prevent that the two breaks away from because of pressure difference in the drain process.
The length of the joint of first connecting tube described in the utility model and second connecting tube is not less than 10cm respectively, and easy-to-operat person both hands grip respectively, and it is dangerous to avoid when carrying out the calcination sterilization burn taking place.
The joint of first connecting tube described in the utility model and second connecting tube is straight tube.
The external diameter of the joint of first connecting tube described in the utility model and second connecting tube is determined according to used silicone tube or fluid flow, and will be guaranteed that the body tail end can pack in the silicone tube and the formation sealing.The body wall thickness of described first connecting tube and second connecting tube is consistent, is 1-2mm.
First connecting tube described in the utility model and second connecting tube all can adopt high temperature resistant material to be prepared from, for example pyroceram, stainless steel etc.And owing to contain salt mostly in the drain composition, stainless steel is had corrosive action, and the stainless joint cost is higher, the utility model preferably adopts pyroceram.
Compared with prior art, the utlity model has following beneficial effect:
(1)Of the present utility model simple in structure, for cone seal connects, need not to adopt seal washer, and two joints can peg graft simply and separate between its first connecting tube and second connecting tube.
(2)The utility model is established at least one pair of symmetrical grab at the carrier of first connecting tube, the grab of at least one pair of symmetrical distribution is established in the cutting graftage part of second connecting tube, grab on the carrier is opposite with the direction of the grab on the cutting graftage part, can use elastic cord to be hooked on the grab further bundlees fixing to first connecting tube and second connecting tube, prevent that the two breaks away from because of pressure difference in the drain process, need not to be equipped with jump ring, very easy to use.
(3)The utility model adopts high temperature resistant material to make, and can carry out the high pressure moist heat sterilization, and high temperature resistant flame calcination can be satisfied the requirement of the aseptic connection of bioreactor.
(4)Of the present utility model simple in structure, preparation easily, and fabricating cost is cheap.
