Before using the medical devices pressure infusion bag, a comprehensive and detailed inspection is the key to ensuring the safety of infusion and avoiding medical risks. These inspections cover multiple aspects, from the integrity of the infusion bag itself to the functional status of the supporting devices, and every link cannot be ignored.
First, check the appearance of the medical devices pressure infusion bag. Carefully check whether there are damage, cracks or tiny pinholes on the surface of the material of the infusion bag. These defects may cause liquid leakage or external bacteria to invade. At the same time, observe whether the color of the infusion bag is uniform, whether there is discoloration or turbidity. If abnormalities are found, it may mean that the material of the infusion bag has changed or the internal liquid has been contaminated, and it should be stopped immediately. In addition, it is necessary to confirm the sealing of the infusion bag, check whether the seal is firm, whether there are signs of looseness or opening, and ensure that there will be no leakage during the pressurization process.
Then check the liquid in the infusion bag. Carefully check the name, concentration and dosage of the liquid to ensure that it is consistent with the doctor's instructions to avoid serious consequences caused by the wrong use of drugs. Observe the properties of the liquid to check whether it is clear and transparent, and whether there are precipitation, flocs or discoloration. Under normal circumstances, the infusion liquid should have a uniform texture. If there are abnormalities such as turbidity or crystallization, it indicates that the liquid may have deteriorated or chemically reacted and cannot be used. At the same time, pay attention to the expiration date of the liquid. The safety and effectiveness of liquids that have exceeded the shelf life cannot be guaranteed and must be strictly prohibited.
Inspection of the infusion line is also crucial. Carefully check whether the infusion tube is intact and undamaged, and whether there are any bends, twists or blockages. Bent lines will hinder the flow of liquid and cause poor infusion; while blockages may prevent the pressure from being transmitted normally, affecting the pressurization effect. In addition, check whether the infusion tube is tightly connected to the infusion bag and infusion needle to ensure that there will be no falling off or leakage during the pressurization process. For infusion lines with filters, it is also necessary to check whether the filter is clean and whether it functions normally to prevent impurities from entering the human body.
Inspection of the pressurization device is an important step before use. If it is a manual pressurization device, check whether the air bag is intact, whether there is any damage or leakage, and whether its elasticity is normal when pressing the air bag, and whether it can be inflated and deflated smoothly. For automatic pressurization equipment, it is necessary to confirm whether the power connection is stable, whether the equipment is running normally, whether the display screen is clear and accurate, and whether the parameter settings meet the requirements. At the same time, check whether the connection between the pressurization device and the infusion bag is firm to avoid separation or leakage during the pressurization process.
The accuracy of the pressure monitoring component is directly related to the safety of infusion. Check whether the pressure gauge or pressure sensor is working properly, whether the pointer is flexible and can be accurately reset to zero, and whether the value displayed on the electronic display is stable and reliable. If there is an error or failure in the pressure monitoring component, it may cause insufficient pressurization to affect the infusion speed, or excessive pressurization may cause serious complications such as vascular rupture. Therefore, it is necessary to ensure that the pressure monitoring equipment is in good condition and can be compared and calibrated with standard pressure equipment when necessary.
In addition to the equipment itself, the use environment must also be checked. Ensure that the infusion site is clean, quiet, and well-lit to facilitate observation of the infusion situation. Check whether the infusion stand is stable, the height is appropriate, and whether the infusion bag can be safely hung. At the same time, ensure that there are no sharp objects or other items that may damage the infusion bag in the surrounding environment to prevent the infusion bag from being damaged due to accidental collision during the infusion process.
Finally, medical staff themselves also need to do a preparatory inspection. Confirm that they are familiar with the use and precautions of the medical devices pressure infusion bag, and wear necessary protective equipment, such as gloves and masks, to avoid improper operation or cross infection affecting the safety of infusion. At the same time, check the patient information again to ensure that the infusion object is accurate, and explain the purpose and precautions of the infusion to the patient and family members to obtain their cooperation and understanding. Only through the above comprehensive and detailed inspections can the pressurized infusion process be ensured to be carried out safely and smoothly.
