Abstract
The present invention relates to a kind of technology of manufacturing animal experiment fistula and animal bile drainage tube.Make mould with rustless steel or plastics or common metal material, on mould, be coated with one deck releasing agent, silicone rubber is rolled into thin piece, being cut into required size is attached on the mould, with the pressurization that heats up of general high voltage autoclave, make silicon rubber formedly, can obtain animal experiment fistula or animal bile drainage tube.This technology is very easy, the one step cure molding, and production cost is low.And the product quality of producing obviously to be better than with rustless steel, plastics or latex be the common fistula and the biliary drainage pipe of material, can permanently be placed on one's body the animal.
Description
The present invention relates to a kind of method of manufacturing animal experiment fistula and animal bile drainage tube.
At present, in animal nutrition research and feedstuff detection, generally adopt the fistula technology both at home and abroad, to zoologize gastral nutritive peculiarity of each section and feedstuff biological nutrition value.The biliary drainage pipe also is widely used in living animal and extracts bile.But general fistula and biliary drainage tube material are rustless steel or common plastics, and these materials have the foreign body effect to animal, and quality is hard, damage the animal body tissue easily, thereby come off.For example, the pig of installation common material duodenum fistula generally can only survive 3-4 month.
And medically, silicone rubber is used more and more widely as orthopedic a kind of new material.West Germany has the precedent of manufacturing fistula with silicone rubber, and domestic also have human silicone rubber to manufacture Bears, Fel Sus domestica drainage tube.But it is no matter external, still domestic.Manufacture fistula and biliary drainage Guan Douxu with the complete equipment that shapes with silicone rubber, these equipment are quite expensive, every processing line needs 100,000 dollars approximately, and technology is numerous and diverse, need two sections sulfurations to make silicon rubber forming, promptly, handled 15-20 minute under pressure 50 kg/cm, under 150-180 ℃ of temperature, handled 4 hours more earlier at temperature 130-140 ℃.User according to present animal experiment fistula and biliary drainage pipe is not many, and be starved of this situation for fields such as animal nutrition researchs, utilize whole set of processing equipment production, cost is too high, very uneconomical, the utmost point is necessary to find a kind of manufacture technology simple, low processing cost be the technology of manufacturing animal experiment fistula and animal bile drainage tube of raw material with silicone rubber.
It is easy that purpose of the present invention just is to create a kind of manufacture technology, and processing cost is low, and what do not need special machine equipment is the technology of manufacturing animal experiment fistula and animal bile drainage tube of raw material with silicone rubber.Utilize this technology both can produce the animal experiment fistula, also can produce the animal bile drainage tube.
The animal experiment fistula of indication of the present invention and the manufacture technology of biliary drainage pipe comprise: (1) makes mould with rustless steel or plastics or common metal material.The shape and size of mould are determined the fistula of required use or the requirement of biliary drainage pipe according to kind and the individual size of animal, be can be T shape, J-shaped or the like as shape.(2) on mould, be coated with one deck releasing agent, silicone rubber sleeve is taken off from mould easily, the most handy CTM101 releasing agent.(3) with general tool such as waddy, vial etc. silicone rubber is rolled into the thin plate of desired thickness, again thin plate is cut into suitable size, be attached on the mould.Gauge of sheet and size can arbitrarily be determined as required.(4) mould that will post silicone rubber is put into high-pressure sterilizing pot intensification pressurization, after the pressure liter reaches 1.4 kg/cm, keeps about 15 minutes, makes silicon rubber forming, takes off silicone rubber sleeve from mould after the blood pressure lowering.Can obtain soft and high-intensity fistula or biliary drainage pipe.
The used silicone rubber material of the present invention is the homemade silicone rubber of G-146 type preferably.The high-pressure sterilizing pot that pressurizes that is used to heat up can be common portable medical high-pressure sterilizing pot or other high-pressure sterilizing pots.
The animal experiment fistula of indication of the present invention and the manufacture technology of biliary drainage pipe, its advantage is: (1) does not need special machine equipment, consumption of raw materials is few, technology is also very easy, the employing one step cure is shaped, only need 1.4 kg/cm pressure, and do not resemble pressure that general technology needs two sections vulcanization formings and 50 kg/cm thereby low processing cost.(2) can change mould neatly as required, thereby produce the fistula or the biliary drainage pipe of different shape and size.(3) good product quality that comes out with this explained hereafter, obviously being better than with rustless steel or plastics or latex is the common fistula and the biliary drainage pipe of material, can permanently be placed on one's body the animal.
2.1 centimetres of one: one bores of embodiment, long 9 centimetres of horizontal end, long 12 centimetres of straight end, the T shape fistula manufacture technology that thickness is about 0.3 centimetre.
(1) be 2.1 centimetres with two external diameters, length is respectively the round metal bar of 9 centimetres and 12 centimetres, is welded into T shape, is about to a long welded top in one short middle part, and making a straight end is 12 centimetres, and horizontal end is 9 centimetres a T shape metal die.
(2) claim about 60 grams of homemade silicone rubber of G-146 model, be rolled into thickness and be 0.3 centimetre thin piece, be cut into 6.6 centimetres wide, 9 centimeter length and 6.6 centimetres wide, 12 centimeter length each one again.
(3) be coated with one deck CTM101 releasing agent on mould, the silicon rubber thin piece of 9 centimeter length be attached to the horizontal end of mould again, the silicon rubber thin piece of 12 centimeter length is attached to the straight end of mould, and seam is pinched flat with hands, do not stay the slit.
(4) mould that will post silicone rubber places the pressurization that heats up of portable medical high-pressure sterilizing pot, after pressure reaches 1.4 kg/cm, keeps about 15 minutes, makes silicon rubber forming.
(5) after the blood pressure lowering cooling, the silicone rubber of the horizontal end of mould being cut off from the centre, taken off silicone rubber sleeve, promptly is soft and high-intensity T shape fistula.
Two: one horizontal end internal diameters of embodiment are 1.2 centimetres, 3 centimetres of length, and directly holding internal diameter is 0.5 centimetre, 20 centimetres of length, the manufacture technology of the T shape biliary drainage pipe that thickness is about 0.2 centimetre.
(1) selecting a diameter is 1.2 centimetres, and long 3 centimetres round iron bar at round iron bar long 20 centimetres, that diameter is 0.5 centimetre of the position, middle of this iron welding, obtains a T shape metal die.
(2) claim the homemade silicone rubber of G-146 type about 8 grams, be rolled into thickness and be 0.2 centimetre thin piece.
(3) after being coated with one deck CTM101 releasing agent on the mould, above the silicon rubber thin piece is attached to, pinch flatly, make thickness even.
(4) mould that will stick silicone rubber places the pressurization that heats up of portable medical high-pressure sterilizing pot, after pressure reaches 1.4 kg/cm, keeps about 15 minutes, makes silicon rubber forming.
(5) after the blood pressure lowering cooling, the silicone rubber tube of the horizontal end of mould is broken from the centre, take off silicone rubber sleeve, promptly obtain T shape biliary drainage pipe.
