Abstract
The present invention discloses a method for manufacturing a silicon rubber pipe with a built-in steel wire, which has the steps that after the steel wire is dipped with glue firstly, the steel wire is heated and solidified, and then, the well solidified steel wire is put into a mould. Glue stocks are added in, mould pressing sulfidation forming is conducted, and finally, mould release is conducted. The present invention adopts a mould pressing forming method, only a common rubber mould pressing forming machine is needed, the steel wire is added in a guide pipe, and the bend resistance, the distortion resistance, the anti-oppression safety and the flexibility of the guide pipe are improved. The present invention has the advantages of simple technology method without special equipment and greatly reduced production cost, and likewise, the processing quality of an extrusion forming method can be achieved.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of manufacture method that is built-in with the silicone rubber tube of steel wire.
Background technology
Prior art has at tracheal catheter increases steel wire, intensity and softness with reinforced pipe, the safety of guaranteeing respiration channel is unobstructed, mainly contain two kinds on pvc pipe band steel wire and silicon rubber pipe racks steel wire at present, the PVC material can only be applicable to disposable use, and the affinity of PVC and human body is poor than silicon rubber, and has potential bad reaction, American-European countries to begin progressively to eliminate the PVC material to be used for medical application.Existing built-in steel wire silicone rubber tube mainly adopts extruding-out process, needs special-purpose extrusion equipment, complex process, production cost height.
The conduit of built-in steel wire can be applicable on a lot of medicine equipments, for example laryngeal mask.In order to keep unconscious patient respiration ventilation, must set up respiration channel to it, laryngeal mask is exactly that the patient who is used for surgery anesthesia, critical patient rescue or other assisted respiartions sets up the medicine equipment of artificial airway's ventilation.Use laryngeal mask airway device more easily to insert and set up respiration channel in the patient body, general operation person just can use through short-term cultivation, and is therefore also very suitable in the occasion of first aid.Because laryngeal mask airway device does not need to contact with the inner passage of tracheae sensitivity just can be to patient's lung inflation, therefore the stimulation of patient's mucosal tissue and the degree of damage are greatly alleviated, and the respiration channel size of being set up is significantly greater than the respiration channel of being set up by trachea cannula.Simultaneously, less during owing to insertion, therefore also less to patient's potential injury to the control action at positions such as patient's head, neck.Because above-mentioned advantage, laryngeal mask airway device has become more and more popular since the nineteen eighty-three invention.But it is higher that the defective of existing laryngeal mask airway device is exactly a cost, especially silicon rubber laryngeal mask, critical technological point wherein is how to add steel wire in the tracheal catheter of laryngeal mask, security of compeling with the anti-bending, warp resistance, the resistance to compression that improve conduit and the displacement that reduces laryngeal mask.
Summary of the invention
The objective of the invention is and will address the deficiencies of the prior art, a kind of manufacture method of silicone rubber tube of built-in steel wire is provided, its technology is simple, and production cost is lower.
The object of the present invention is achieved like this: a kind of manufacture method of silicone rubber tube of built-in steel wire is characterized in that may further comprise the steps: 1. steel wire is carried out being heating and curing after impregnation is handled; 2. the steel wire that is cured is put into mould, add sizing material, carry out the molded vulcanization moulding; 3. the demoulding.
The temperature that is heating and curing behind the described steel wire impregnation is 100-200 ℃, and the time is 5-30 minute.
The temperature of described molded vulcanization moulding is 110-190 ℃, and cure time is 100-800 second, and sulfide stress is 10-20Mpa, and venting is more than 2 times or 2 times.
The spue line of described silicone rubber tube is located at the right and left of silicone rubber tube.
The present invention adopts compression molding method, only need common rubber pattern pressing machine, in silicone rubber tube, add steel wire, security that the anti-bending of raising conduit, warp resistance, resistance to compression are compeled and the flexibility that improves tracheal catheter, process is simple, do not need special equipment, production cost greatly reduces, and can reach the crudy of extrusion moulding equally.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
The specific embodiment
The present invention is a kind of manufacture method of silicone rubber tube of built-in steel wire, adopt compression molding method, may further comprise the steps: at first steel wire is carried out impregnation and handle in liquid silastic, be heating and curing then, make steel wire and silicon rubber combination in next step mold process get better; Again the steel wire that is cured is put into mould, add sizing material, carry out the molded vulcanization moulding; Finally demould promptly obtains being built-in with the silicone rubber tube finished product of steel wire.The curing of different sizing materials and the technical parameters such as temperature and time of molded vulcanization moulding are different, general, the temperature that is heating and curing is 100-200 ℃, time is 5-30 minute, the temperature of molded vulcanization moulding is 110-190 ℃, cure time is 100-800 second, and sulfide stress is 10-20Mpa, and venting is more than 2 times or 2 times.
The spue line of prior art pipe is located at the upper and lower of pipe, and the mouth of a river is also just at the upper and lower of pipe after the machine-shaping, and this just in time is the position that directly contacts with tissue, if crudy is bad burr is arranged, and just is easy to tissue is caused damage.The present invention is located at the right and left of pipe with the spue line of silicone rubber tube, and the mouth of a river makes the mouth of a river can directly not contact with tissue also just at the right and left of pipe after the machine-shaping, effectively avoids tissue is caused latent lesion.
Embodiment
Below be object lesson by laryngeal mask, in the tracheal catheter of laryngeal mask, add steel wire.
Capital equipment includes vulcanizing press, opening rubber mixing machine, baking oven etc.Technological process is as shown in Figure 1:
At first, be ready to liquid silastic, spiral helicine wire spring immersed carry out the impregnation processing in the liquid glue, be heating and curing with baking oven, the temperature that is heating and curing is about 150 ℃, and the time is 20 minutes;
Then, the steel wire that is cured is socketed in outside the iron core (the iron core surface has coated interleaving agent), put into mould then together, spue line is located at the right and left of pipe, adds sizing material in mould, carries out the molded vulcanization moulding, temperature is controlled at about 160 ℃, cure time is 400 seconds, and sulfide stress is 10-20Mpa, exits 2 times;
Obtain finished product behind the demoulding.
