New solution of pre filling silicone oil spraying system

Pre filling / pre filling syringes are mainly used in the fields of insulin, tumor and vaccine The rapid growth of the market demand for pre filling / pre filling syringes is mainly due to the fact that pre filling / pre filling syringes can simplify clinical operation, be convenient and practical, reduce the injection cost of patients, avoid repeated suction after using diluent, and reduce secondary pollution The pharmaceutical market is changing, the number of biotechnological therapies and candidate drugs that can be administered by injection is increasing, and they cover a wide range of treatment areas Some biotechnological drugs need to be injected frequently by the patients themselves The pre filling / pre filling syringe saves some operation steps, making the use faster and easier The patients benefit from the convenience of pre filling / pre filling syringe In addition, pharmaceutical manufacturers have changed some drugs from lyophilized dosage forms to liquid dosage forms to facilitate the filling of pre filled / pre filled syringes The pre filling / pre filling syringe comprises a needle tube, a push rod, an injection needle and a needle protection cap In order to ensure that the rubber piston on the push rod of the assembly can slide freely in the inner cavity of the needle tube, the inner cavity of the needle tube and the rubber piston should be lubricated with silicone oil during the production process of the pre filling / pre flushing tube syringe assembly The amount of silicone oil is too small, which affects the sliding performance of the rubber piston of the push rod in the inner cavity of the needle tube; the amount of silicone oil left in the inner cavity of the needle tube and the rubber affects the quality of the medicine packaged by the assembly 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 In order to solve the problem of traditional silicone oil 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) fsp-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 Fsp-ap micro fluid pump system adopts the precision sapphire grade ceramic pump technology, which has the characteristics of high efficiency, high precision, corrosion resistance, wear resistance and pollution-free It is widely used in the fluid control, maintenance free design, extremely stable and reliable, high-efficiency production in the pharmaceutical, biochemical, medical equipment, semiconductor industry, etc., making fsp-ap micro pump system It has become the choice of liquid filling and atomization spraying for middle and high-end 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 FSP-AP microfluidic control system can be used in conjunction with high precision, trace (up to 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 spraying solution Sonicair spray system has been proved to be very effective in the pre filling / pre filling syringes, drug scaffolds and syringe needles It has been widely used in the North American market, providing an ideal technology upgrading solution for manufacturers who want to eliminate the immersion based silicone oil lubrication solution Fsp-ap + sonicair atomizes the fluid in a special way Unlike other gas nozzles that depend on time and pressure to atomize the fluid, sonicair atomizer is effective through a positive displacement fluid injection and transfer system The injection system completes a precise 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 can be selected and process control is carried out to achieve the desired spray effect, so that conical or beam type injection modes can be obtained conforming and continuous Conical spray has been proved to be an effective way to spray the inner wall of syringe The air flow from the nozzle at the same time helps to spread the atomized fluid evenly around The system composition: Online spraying platform fsh-ap fluid pump system sonicair atomizing nozzle system characteristics: ● small, medium and large-scale automation platforms to meet the needs of different production lines ● the 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 grade to NL grade ● atomization effect: fine, uniform, 5-50um fluid atomization ● high precision, up to 0.5% CV precision ● maintenance free design, extremely stable and reliable ● high efficiency, high yield, bringing greater value to customers ● successful cases, widely used by well-known multinational companies It is suitable for pre filling syringe, pre filling syringe and other applications requiring micro high precision spraying
