Interpretation Of Sensory Experts: Application Of Needleless Connector
With the continuous upgrade of drug-resistant bacteria, each puncture and indwelling every day may increase the incidence of catheter-related bloodstream infections. For patients, vascular access is a life-saving pathway, not a fatal dead end! So, how to choose the infusion connector and how to carry out routine maintenance to effectively reduce the incidence of catheter-related bloodstream infections?
Intravenous infusion is an important way of clinical treatment, covering parenteral infusion, nutritional support, medication and infusion treatment, so it is widely used. Antibiotics are also widely used in clinical practice. Its invention can be described as a pioneering act of the 20th century. However, in recent years, bacterial resistance has also been continuously emerging and upgraded. For penicillin drugs, the original powerful effect is now inadequate.
It is frightening that when multi-drug resistant bacteria encounter vascular access, each puncture and indwelling every day will increase the incidence of catheter-related bloodstream infections, bring more harm to patients, and the mortality rate can even reach 45.3%. Vascular access should be a life-saving channel, not a fatal dead end. So, how to choose the infusion connector and how to carry out routine maintenance to effectively reduce the incidence of catheter-related bloodstream infections?
Why emphasize the choice of needleless connectors?
30% of catheter-related infections are caused by contamination of the catheter connector [2]. Among them, incomplete disinfection and flushing of the joint is one of the important reasons for the blocked pipe and the bacterial value, which is also greatly related to the design of the needleless joint itself.
Before each connection is used, it is necessary for nurses to wipe the surface of the connector with a mechanical method for 5 to 60 seconds. The purpose is to reduce bacterial contamination on the surface of the connector. However, if the surface of the joint is uneven or not tight, there are grooves or gaps. Then, you can't clean it thoroughly with hard and long-lasting wiping.
In addition, flushing the joint is also a necessary operation before and after each use, in order to rinse the drug, blood or other nutrients remaining in the joint, so as to avoid providing strong conditions for bacterial colonization. However, if the joint is opaque and no flushing effect is observed, then for substances that are not easily flushed, such as blood, high-viscosity liquids, lipid-containing nutritional preparations, etc., there may be flushing in place, increasing catheter blockage and bacterial colonization, Risk of infection.
Therefore, as pointed out in the Expert Consensus on Best Nursing Practices for the Prevention and Control of Catheter-Related Infection: Although it is not clear that certain types of needle-free infusion joints have advantages in preventing CLABSI and thrombotic occlusion, the smooth surface of the infusion The joints are easier to sterilize, and the transparent structure joints are easy to see the flushing effect.
In addition, by selecting the indwelling needle with a removable and replaceable pre-connected infusion connector, you can also replace the connector immediately when necessary to reduce the incidence of infection, such as the discovery of blood or other residues in the needle-free connector, When the connector or other additional device is removed or suspected of contamination, the original catheter is retained and unnecessary secondary puncture is performed on the patient.
Studies show that 71% of catheter-related bloodstream infections occur on the fifth day after implantation, suggesting that the biggest factor that causes CLABSI is during maintenance.
Sealing tube management is an important operation for daily catheter maintenance, and it is also one of the important links to prevent catheter blockage and blood flow related infections. Compared with using a disposable syringe to manually pump the flushing solution, using a pre-filled syringe directly can save the preparation time of the flushing solution, can also ensure the aseptic technique, and reduce the catheter or liquid contamination caused by the hands of the nursing staff. Due to the huge clinical use of vascular access, the problem of infection cannot be overlooked. Among them, the reasonable selection and standardized management of infusion tools are particularly important. Selecting infusion connectors with smooth surfaces, transparent shells, and detachable, and using pre-filled flushers to perform routine catheter maintenance can effectively control the occurrence of catheter-related bloodstream infection Let life channel fulfill its mission.

Production Process Requirements For Syringe Mould
Syringes produced by syringe moulds are widely used in daily life. We use them every time we go to the hospital. In a rapidly developing society, the medical field is also developing rapidly, and the production of medical moulds is becoming more and more extensive.
Design of cooling system for syringe mould
The design of the cooling system is a relatively complicated task, that is, the cooling effect and the uniformity of the cooling must be considered, and the influence of the cooling system on the overall structure of the mould must be considered. The specific location and size of the cooling system must be determined; key parts such as moving moulds Or the cooling of inserts; the cooling of side sliders and side cores; the design of cooling elements and the selection of cooling standard elements. Syringe mould company began to analyze these series of problems when the mould was designed. The mould uses circulating water to flow in each part of the mould, which reduces the cooling time during injection, improves product production efficiency, and greatly reduces production costs.
The syringe mould is non-toxic, sterile, high-gloss, and medical plastic according to the needs of the syringe. For these requirements, it is necessary to choose a suitable quenched steel. The second syringe needs to be sealed, and the processing size of the mould is controlled to be within 0.03 mm. The injection mould company has self-inspection on the finished workpiece, re-inspection according to the 3D drawing, and reports according to the measurement point. First, the QC department supervisor inspects it, and then re-inspects it in the project department. To the assembly shop.
As people pay more and more attention to health, the market demand for Syringe Mould is growing. Yuhuan Shengjiu Mould Co., Ltd. makes these uses of medical mould more with its superb technology. We are a professional syringe mould manufacturer and syringe mould supplier in China. Welcome to buy: https://www.medicalmould.net/

Medical Mould-Hot Runner System Process Features
Hot runners are heated to ensure that the plastics in the runners and gates remain molten. Hot runner systems generally consist of hot nozzles, manifolds, temperature control boxes, and accessories. Hot nozzles generally include two types: open Hot nozzles and needle valve hot nozzles, because the form of the hot nozzle directly determines the selection of the hot runner system and the manufacture of the mold, the hot runner system is often divided into open hot runner systems and needle valve hot runner systems accordingly.
The hot runner plays a very important role in the production molding. The hot runner system is a combination. Not a single product. It includes a nozzle, a runner plate, a thermostat, and a diverter plate. These together form the hot runner system. As a common part of the injection mold system, the plastics in the runner and the gate are kept molten by heating. Because the heating rod and heating ring are installed near or in the center of the runner, the entire runner from the injection nozzle of the injection molding machine to the gate is in a high temperature state, so that the plastic in the runner is kept molten. Generally, it is not necessary to open the runner to take out the condensation after the shutdown. Material, only need to heat the runner to the required temperature when the machine is turned on again. Therefore, the hot runner process is sometimes referred to as a hot header system, or as runnerless molding.
Yuhuan Shengjiu Mould Co., Ltd. is a new-type medical mould manufacturer and supplier in China, which has developed a complete hot runner system. The main production and supply: syringe mould, safety needle mould, oxygen mask mould, needleless connector and other medical mould products.
