Abstract
The utility model discloses a liquid matching device with negative pressure for vein injection liquid, which is composed of a negative pressure generator, a filter, two roots of connecting pipes and three roots of large injection needle heads. The utility model has the advantages of simple structure, convenient operation, high work efficiency, good use effects, etc. The liquid matching mechanization of vein injection is basically achieved, a medical care personnel's labor intensity is reduced, the problems that manual liquid matching is easy to contaminate and cross-infect, etc. are solved, and utility model is quite welcome by the medical care personnel.
Description
This utility model is a kind of for intravenous fluid adds the device of other medicinal liquid, belongs to field of medical appliances.
Intravenous injection is widely used in clinical as effective medical procedure, before intravenous injection, generally all need in injection, add other medicinal liquid to increase curative effect, the method of dosing at present generally is by manually with syringe the medicinal liquid that need add being extracted out in the big bottle that is expelled to injection again in ampoule, a large amount of injection all will be prepared every day on time by hospitals at different levels, not only labor intensity is big, efficient is low, and has the medicinal liquid cross-contamination and infiltrate insoluble matters such as cullet easily and work the mischief to patient.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, to provide a kind of simple in structure, the intravenous fluid negative pressure liquid dispenser of high efficiency.
This utility model mainly is made up of negative pressure generator, filter, two connection tubes and three large size injection needles, its annexation is: an end of a connection tube is connected with the suction hole of negative pressure generator, syringe needle of another termination, this syringe needle passes the injection bottle stopper and is inserted in the injection bottle, the middle part of another root connection tube is connected to a filter, two ends respectively connect a syringe needle, and a syringe needle is placed in the medicinal liquid of medicinal liquid ampoule, and another root syringe needle passes the injection bottle stopper and is inserted in the injection bottle.Wherein, filter uses medical filter or Dispoable medical filter, and connection tube uses flexible pipe for medical purpose or Dispoable medical flexible pipe.
Accompanying drawing is the structural representation of this intravenous fluid negative pressure liquid dispenser.
Be further described as follows in conjunction with the accompanying drawings:
One of connection tube 9 is terminated on the suction hole 10 of negative pressure generator 11, the other end of connection tube 9 is connected with syringe needle 6, the middle part of connection tube 3 is connected to a filter 4, the two ends of connection tube 3 respectively connect a syringe needle 2 and 7, syringe needle 6 and syringe needle 7 pass bottle stopper 5 and insert in the injection bottle 8, syringe needle 2 is placed in the medicinal liquid of ampoule, when connecting the working power of negative pressure generator, by the air in the connection tube 9 suction injection bottles 8, make injection bottle produce negative pressure, medicinal liquid in the ampoule 1 can be sucked in the injection bottle by connection tube 3, the medicinal liquid that syringe needle 2 being put into other ampoule again after sucking can will need to prepare very soon all sucks injection bottle 8, because medicinal liquid filters through filter when sucking, cullet and insoluble matter in the ampoule are not entered in the injection bottle, avoided the malpractice that causes because of cullet effectively.
The utlity model has simple in structure, easy to use, efficient is high and the advantage such as effective, substantially realized dosing mechanization, reduced medical personnel's labour intensity, the dosing time is also fast again than manual dosing, the problems such as the contaminated and cross-infection of soup have been solved, through on probation, deeply be subjected to medical personnel's welcome.
