Materials and Introduction of Disposable Syringes

Disposable syringe, product performance, structure and composition The disposable syringe consists of a jacket, a core rod, a rubber stopper, a cone head, a handle and a cone head. The scope of application of the product is matched with disposable injection needles for subcutaneous, muscular, intravenous injection, blood drawing or drug dissolution. It is usually polyethylene, or PP, which is usually medical grade and has relevant certification. However, as far as I know, not all hospitals use medical grade PP raw materials in the strictest sense. Syringe manufacturers also determine the quality of materials according to the size and grade of hospitals. This material should have 1. Multiple sterilization options (high pressure, hot steam, ethylene oxide, gamma ray, electron beam). 2. Excellent transparency and luster. 3. Superior rigidity and impact resistance balance minimum distortion. 4. Good low-temperature impact resistance. Only in this way can the needs of disposable syringe materials be met.
The principle of disposable precision infusion device: under the effect of atmospheric pressure, the liquid in the bottle flows into the drip bucket along the thin infusion hose. When the water column pressure of the drip bucket is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. How to operate the disposable precision infusion set, and how to operate the disposable precision infusion set: Before use, the medical staff should check the sterilization validity period of the disposable infusion set and whether the package has air leakage and other abnormalities, take out the infusion set, hang the infusion bottle with the conical joint on the infusion rod, exhaust the air to the lower end of the infusion tube, close the regulator, and then needle the vein into the sterilized vein, after fixing, Untie the tourniquet and adjust the flow rate. Of course, the medical staff who use the disposable precision infusion set are all trained. Of course, they know how to operate the disposable precision infusion set. Those who have not been trained should not operate it at will.
Disposable syringes can be divided into three categories according to their purposes: serious pollution, general pollution and basically no pollution. For disposable syringes with different pollution levels, their treatment methods are also different, so how to classify them specifically: 1. Seriously polluted disposable syringes: syringes that have been used in direct contact with patients' body fluids, such as blood, pleural effusion, ascites, etc., because patients' body fluids are potential sources of infection. 2. Generally contaminated disposable syringes: that is, only the needle part is the syringe that contacts the patient, such as some syringes used for routine injection and infusion, and usually hanging anti-inflammatory water. 3. Basically pollution-free disposable syringes: disposable syringes that do not contact patients directly are basically pollution-free, such as those used when adding drugs. Of course, improper operation and contamination should be excluded. This is the classification of disposable syringes. If you want to deal with it, you should deal with it according to such a classification method. Different pollution levels require different treatment methods. Disposable syringes belong to medical waste. They cannot be discarded randomly like ordinary garbage and put in trash cans for recycling. This kind of medical waste is generally subject to centralized harmless treatment, including incineration, destructive disinfection, and deep burial after incineration. When safety box is used for incineration, the temperature shall be above 800 ° C to reduce air pollution; If there is no safety box, the incinerator with low temperature (300 ° C~400 ° C) can also be used. In areas where there are no destructors and incinerators, the method of deep burial after incineration can be adopted. It is important to remind everyone here that disposable syringes should not be recycled at will. There will be some drug residues in disposable syringes that cannot be cleaned, so you must pay attention.
