Description
Technical field
This utility model relates to medical auxiliary apparatus, is specifically related to a kind of transfusion pH value checkout gear.
Background technology
Transfusion (infusion solution) is the large bolus injection liquid inputted by intravenous drip in body, in the infusion bottle being packaged in glass or plastics or transfusion bag; Drip speed by transfusion device adjustment during use, continue and stably enter vein.
The pH value of transfusion should meet the requirements (General Requirements pH value is 4-9, best 5-8), and pH value ensureing on curative effect and the stable basis of goods, should make every effort to the pH value close to human body, too high or too lowly all can cause acid alkali poisoning, even can cause phlebitis.In addition, in drug solution preparing process, the change of pH value may be caused during multi-medicament compatibility, thus make wherein a certain one-tenth analyze precipitation or other changes, therefore carrying out part medicinal liquid needing in process for preparation to measure its pH value, after adjusting its pH value as required again, continue preparation, to improve drug solution preparing quality and medicine stability.
At present, to the method that the pH value of transfusion detects, generally with syringe, the transfusion in infusion bottle or transfusion bag is released, then drop on pH reagent paper and detect, or detect with other equipment, inconvenience operates at any time, and may cause the pollution of environment, is inconvenient to especially operate for the transfusion used.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of structure transfusion pH value checkout gear simple, convenient to operation.The technical scheme adopted is as follows:
A kind of transfusion pH value checkout gear, comprise syringe, syringe needle, piston and push-pull bar, syringe front end is located at by syringe needle, the cavity of syringe needle is communicated with the cavity of syringe, piston to be located in syringe and with the inner surface close contact of barrel sidewall, push-pull bar front end is connected with piston, it is characterized in that: described transfusion pH value checkout gear also comprises pH reagent paper and pH reagent paper accommodation chamber, and pH reagent paper accommodation chamber is made up of transparent material; Barrel sidewall front portion is provided with liquid outlet, and the cavity of syringe is communicated with the cavity of pH reagent paper accommodation chamber by this liquid outlet; PH reagent paper is located in the cavity of pH reagent paper accommodation chamber.
During use, syringe needle inserts in infusion bottle or transfusion bag, then pulls back push-pull bar, piston is moved backward, can extract appropriate transfusion (namely having appropriate transfusion to enter the cavity of syringe) from infusion bottle or transfusion bag; Afterwards syringe needle is extracted from infusion bottle or transfusion bag; Pull back push-pull bar further again, when piston crosses liquid outlet, the transfusion in syringe cavity to enter in the cavity of pH reagent paper accommodation chamber through liquid outlet and contacts pH reagent paper, by observing the color of pH reagent paper, the pH value of transfusion can be differentiated, thus realize the detection of transfusion pH value.Because syringe in use procedure is aspiration phases always, transfusion remains wherein after entering transfusion pH value checkout gear, the pollution spilling and cause environment of therefore can effectively avoiding infusing.
In preferred version, liquid outlet seals by above-mentioned piston, and the cavity of pH reagent paper accommodation chamber is in vacuum state.Like this, when piston crosses liquid outlet, because the cavity of pH reagent paper accommodation chamber is in vacuum state, and outside air can enter in the cavity of syringe through the cavity of syringe needle, utilize draught head, the transfusion in syringe cavity is more successfully entered in the cavity of pH reagent paper accommodation chamber.In addition, preserve pH reagent paper under vacuum conditions, can guarantee that pH reagent paper is from pollution.
In preferred version, the outer surface of above-mentioned barrel sidewall is pasted with standard color comparison card.By arranging standard color comparison card, the pH value of be more convenient for operator's contrast reading transfusion fast.
Usually be also provided with Tip protection cover outside above-mentioned syringe needle, between Tip protection cover and syringe needle, leave gap.Use front Tip protection cover to be covered by syringe needle, shield; First take off Tip protection cover during use, from infusion bottle or transfusion bag, extract appropriate transfusion and after syringe needle is extracted from infusion bottle or transfusion bag, again load onto Tip protection cover, in case syringe needle is hurted sb.'s feelings, and can prevent transfusion from spilling and contaminated environment further.
Can be transparent plastic (as polymethyl methacrylate, polrvinyl chloride, transparent polypropylene etc.) or glass for making the transparent material of pH reagent paper accommodation chamber.Above-mentioned piston can adopt rubber, TPO elastomeric material is made.
This utility model structure is simple, production cost is lower, and convenient to operation, can not cause the pollution of environment, can realize infuse pH value at any time with survey, also can realize detecting the transfusion used or detecting medicinal liquid in drug solution preparing process.This utility model can realize single use, and testing process can not pollute transfusion.
