Solution of silicone oil spraying for high pressure contrast injector

With people's high attention to physical health, the inspection method of image technology is widely accepted and recognized by people Advanced image technology has replaced the old cutting, sampling and testing The syringe syringe is combined with the high-pressure syringe, and the developer is inhaled into the syringe syringe by the mechanical and electrical control function of the high-pressure syringe, and then injected into the affected area of the inspected patient, and then the clear and stable inspection image is formed by the image scanning equipment, and the actual state of the inspected patient is correctly judged to determine the direction of treatment Disposable high-pressure contrast syringe and accessories are mainly composed of contrast syringe piston, piston with sealing ring, contrast syringe outer sleeve, 6% outer conical joint with locking device, protective sleeve, puncture type drug aspirator / tube type drug aspirator, single connection pipe / multiple connection pipe Additional requirements for disposable high-pressure contrast syringe: 1 There should be no accumulation of lubricants on the inner surface of the syringe casing and the outer surface of the piston sealing ring 2 Transparency The syringe coat has enough transparency 3 Scale line and mark if there are scale line and mark on the contrast syringe, the scale line and mark shall be complete and clear 4 The inner control of the outer cone luer joint on the inner diameter contrast syringe of the cone joint shall not be less than 1.2mm 5 When the tightness is tested according to the requirements, the contrast syringe shall be able to withstand the rated liquid pressure of the matching machine for 30s without rupture (the test time of DSA type contrast syringe with special protective sleeve on the outer sleeve is 8s), and there shall be no leakage between the piston sealing ring and the outer sleeve and between the cone joint and the connector In order to ensure that the piston of the contrast syringe can slide freely in the inner cavity of the syringe shell, the inner surface of the syringe and the rubber piston should be lubricated with silicone oil during the production of the syringe assembly Too little silicone oil affects the sliding performance of the rubber piston in the syringe cavity; too much silicone oil has adhesion on the inner wall of the syringe, which affects the aesthetics and the quality of the medicine in use There are two traditional spraying methods of silicone oil: 1 Pour the needle tube and rubber piston into the silicone oil tank diluted with solvent, soak it and then take it out for drying In the process of drying, the silicone oil will fall off, the silicification is not uniform, the effect is not ideal, and the control of silicone oil consumption is not strict 2 Spray by spray gun, in this way, there are thick edges, uneven, too large particles and other phenomena The ideal spraying effect requires high performance of the liquid adding and measuring equipment, which requires the liquid adding and measuring system to achieve precise and micro spot liquid In addition, a high-performance liquid atomizer is also required In order to solve the problem of traditional silicone oil spraying and realize micro precision spraying, the technical team of Guangzhou feisheng precision equipment Co., Ltd has been focusing on BD, Schott, a well-known medical equipment manufacturer in the United States since 2008 With the introduction of American micro spray technology, we have developed UL and NL level quantitative spray systems, which provide high-precision micro spray system solutions for customers in China and Asia The micro spray system of Guangzhou feisheng company consists of three parts: (1) online spray platform; (2) fsh-ap micro fluid pump system; (3) sonicair precision spray nozzle The on-line spraying platform is driven by high precision servo and equipped with CCD vision detection device, which can detect and locate automatically There are small, medium and large automation platforms to meet the needs of different production lines        FSH-AP The micro fluid pump system adopts the advanced precision sapphire grade ceramic pump technology, which has the characteristics of high efficiency, high precision, corrosion resistance, wear resistance and no pollution Its production line accuracy can reach 0.3% It is widely used in the fluid control of pharmaceutical, biochemical, medical equipment, semiconductor industry, such as liquid point, filling and atomization spraying, maintenance free design, extreme stability and reliability, The fsh-ap micropump system has become the fluid system for filling and atomizing liquid spraying for medium customers Sonicair atomizer adopts special pipeline design and is made of 316 stainless steel It is not easy to change chemicals and has no moving parts or valves, so the spraying effect is stable and reliable Sonicair spray device and FSH-AP microfluidic control system can be used to achieve high precision, micro (NL level), uniform and fast spraying effect The well-known pre filling / pre filling syringe, tube, drug stent and blood vessel company have adopted our spray solutions The customer case proves that sonicair spray system is very effective in spraying pre filled / pre filled syringes, drug scaffolds and syringe needles, and has been widely used in the North American market, providing a technical upgrading solution for manufacturers who want to eliminate immersion based silicone oil lubrication solutions The way of sonicair nozzle atomizing fluid is very special Unlike the gas nozzle which depends on the time and pressure atomizing fluid, sonicair nozzle atomization device is effective through the positive displacement fluid injection transfer system The injection system completes the injection of fluid into the nozzle and injects the fluid into the air flow The atomization field is formed when the fluid is ejected through sonicair nozzle Different nozzle designs and specifications and process control can also be used to achieve the desired spray effect, so that conical and continuous cones (proven to be effective ways of spraying the inner wall of the syringe) or beam injection mode can be obtained The air flow from the nozzle at the same time helps to spread the atomized fluid evenly around The beam jet can optimize the flow through the film substrate in the production of diagnostic test paper System composition: Online spraying platform system features: ● small, medium and large-scale automation platforms to meet the needs of different production lines ● platform system adopts high-precision servo drive, with CCD visual detection device, automatic detection and positioning ● high-precision ceramic pump, sapphire grade, wear-resistant, pollution-free ● Special sonicair precision nozzle ● micro spraying, from UL level to NL level ● atomization effect: fine, uniform, 5-50um size fluid atomization ● high precision, up to 0.5% CV precision ● maintenance free design, extremely stable and reliable ● rate, high yield, bring greater value to customers ● successful cases, widely used by well-known multinational companies ● It is suitable for pre filling syringes, pre filling syringes and other applications requiring micro high precision spraying Typical applications: ● drug stent spraying ● blood collection / pre filling pipe wall spraying ● silicone oil atomization spraying ● other medical equipment spraying ● pharmaceutical, electronic and food industries micro spraying Guangzhou feisheng precision equipment Co., Ltd is a high-tech enterprise specialized in precise fluid control system and solutions The company has rich experience in micro fluid injection, filling, marking, spraying and automatic design and manufacturing It is a leading micro fluid control system company in the industry, serving high-tech enterprises in China and Asia, and creating more value for customers with technology
