Aseptic bulb-tubulating machineTechnical field
The one that the present invention relates to field of medical device in contaminated environment (i.e. ambient non-sterile) by the aseptic bulb-tubulating machine of two aseptic combinations of pvc pipeline.
Background technology
Medical field is when flexible pipe docks, aseptic connection can be able in a closed system for making pipe, the mode of usual employing fusing docking, because pipe is extruded in fusion process, form two blind ends, liquid in pipe is moved apart welding mouth, after welding completes, only need extrude interface gently just can connect two pipes, liquid is allowed to flow to another pipe, be applicable to storage blood bag, blood plasma separation bag, transfering bag or infusion strap is connected on storage blood bag, aseptic bulb-tubulating machine is that two pvc pipelines combine by one in contaminated environment (i.e. ambient non-sterile) exactly, and keep the medicine equipment of connector aseptic condition, in blood collecting and supplying, clinical operation, the fields such as bio-pharmaceuticals are essential, aseptic bulb-tubulating machine can by aseptic for flexible pipe combination in contaminated environment (i.e. non-dust-free sterile room),
Along with the preparation demand of blood constituent uprises, aseptic bulb-tubulating machine is applied to Blood Transfusion Services at different levels more and more, instead of traditional puncture method.Be applicable to the fields such as composition mixing/leucocyte-removing/collector improvement/component separation/displacer improvement/sampling quality control/stem cell process/cell washing, refrigeration, become the requisite apparatus of Blood Transfusion Services at present, the aseptic bulb-tubulating machine of current import is expensive, complex structure, and consumptive material price is high.
Summary of the invention
The aseptic bulb-tubulating machine that the object of the invention is to overcome existing import is expensive, complex structure and the high deficiency of consumptive material price, provides a kind of high performance aseptic bulb-tubulating machine.
The present invention is achieved by the following technical solutions:
A kind of aseptic bulb-tubulating machine, comprise main frame, cutter box, fusion splicing devices, display screen and controller, fusion splicing devices is arranged in main frame cutter box, it is characterized in that: described fusion splicing devices is made up of welding sheet, catheter block, conduit pressing plate, electro-heat equipment, temperature controller and welding sheet elevating mechanism, catheter block is made up of left side catheter block and right side catheter block, gap is provided with between left side catheter block and right side catheter block, temperature controller controls electro-heat equipment to the heating of welding sheet, and welding sheet is controlled to move up and down in the gap of catheter block by welding sheet elevating mechanism, catheter block is provided with 2 conduit troughs, conduit pressing plate is arranged on the top of catheter block, the plasma bags conduit of the catheter block left and right sides and empty bag conduit is placed respectively in 2 conduit troughs, conduit is fixed in conduit trough by conduit pressing plate, conduit pressing plate is provided with pressure pipe tooth, conduit is squeezed into closed state by pressure pipe tooth in conduit trough, left side catheter block is controlled to move forward and backward by controller, right side catheter block is controlled to move left and right by controller, conduit in conduit trough is fused by the high temperature melting contact pin of rising, mobile left side catheter block realizes the docking of plasma bags conduit and empty bag conduit, on the right side of while high temperature melting contact pin declines, catheter block is moved to the left, realize plasma bags conduit and the welding of empty bag conduit under high temperature germ-free condition, welding sheet is fixed in the heating tank of electro-heat equipment, and electro-heat equipment heater element used is single-ended heating tube, and single-ended heating tube heats in the both sides of welding sheet body simultaneously, the fusing-off temperature of welding sheet is 300 DEG C ± 20 DEG C, the conduit trough of described catheter block is made up of 2 conduit troughs, and 2 conduits can realize fusing docking simultaneously.
The present invention compared with prior art has superior performance, function is strong and price is low feature.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, content of the present invention is described further:
As shown be aseptic bulb-tubulating machine structural representation, comprise cutter box 1, catheter block 2, left conduit pressing plate 3, right conduit pressing plate 4, conduit trough 5, display screen 6, cutter box button 7, start button 8, waste paper box 9 and pressure pipe tooth 10.
Specific operation process is as follows:
1, original blood bag or plasma bags to be placed on the right side of machine etc. on blood bag bracket, conduit are pressed into upper conduit groove.
2, by wash solution bag, leukoreduction filter bag or inactivation of virus blood bag are placed on the blood bag bracket on the left of machine, conduit are pressed into downcomer groove.
3, respectively by bottom left conduit pressing plate and right conduit pressing plate.Conduit is made to be squeezed into closed state in pressure pipe tooth.
4, press startup button, aseptic bulb-tubulating machine is started working, and electro-heat equipment generates heat, and heats and fuses sheet to assigned temperature.（300℃±20℃）。
5, fuse sheet to rise, melt disconnected conduit in the middle of the pressure pipe tooth of left and right, remain on 300 DEG C owing to fusing sheet temperature, fuse sheet and be close to the conduit stump melting tab surface and be in germ-free condition all the time.
6, left end conduit moves with left catheter block, and left conduit stump is close to and is melted tab surface and move to assigned address (aliging across fusing sheet with right conduit).
7, while fusing sheet decline, right conduit stump is drawn close left, is merged fusion with left conduit stump.
8, open conduit pressing plate, take out conduit, squeeze conduit fusion place by hand, make conduit open-minded again.
In whole process, conduit stump all the time with fuse sheet and fit tightly, maintain conduit and be in enclosed sterile state all the time from melting the process of breaking to merging.Therefore through two PVC conduits that this aseptic bulb-tubulating machine connects, still keep germ-free condition upon connection.
