Abstract
The utility model belongs to the technical field of medical equipment, particularly relates to a valve type three-way pipe transfusion device. The utility model comprises a needle head, an exhaust pipe, a Murphy's dropper, a dropping pipe, a regulator, and a filter, which a disposable transfusion device is provided with. The utility model is characterized in that one end of a valve type three-way pipe is arranged on the upper end of a terminal filter, and the other end is connected with the dropping pipe. The valve type three-way pipe is arranged on the upper end of the terminal filter so that two kinds of liquid can be simultaneously transfused, and simultaneously other medicine can be directly injected into patients' veins through a medicine pipe in transfusion. All the operation processes are carried out in the fully closed state, and the condition that air enters human bodies' blood can be effectively prevented. The utility model mainly solves the filter problem for pushing and injecting liquid under the condition of salvaging patients. The particulate contamination can be decreased. Compared with the prior art, the utility model has the advantages that the liquid medicine can be saved, the particulate contamination can be decreased, the work efficiency can be improved, etc. The utility model is suitable for being used for salvaging patients, and anaesthetizing patients in operations.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of valve-type tee T transfusion device.
Background technology
In the prior art, clinically the tee T of the disposable transfusion device of Shi Yonging be installed in the Mo Feishi dropper above, can only be in the Mo Feishi dropper liquid feeding, can not import two kinds of liquid simultaneously, need push away medicine directly is connected in syringe between transfusion device terminal and the piercing needle often when giving emergency treatment to a patient, no defecator can't be handled the microgranule in the medicinal liquid between the two, a large amount of particulate matters is entered in the blood vessel of human body, cause particle contamination, these foreign bodies can cause serious harm to patient, comprise the heart, lung, the infringement of kidney and blood vessel, wherein the most serious is pulmonary infarction, the lung granuloma.In addition, Chinese patent 98237053 also discloses and a kind of three-way valve has been contained in transfusion device between drainage screen and the scalp acupuncture, this transfusion device has not solved the particle issues of handling in the medicinal liquid equally, and also valveless control of tee T, in exhaust process, interior air row is unclean for side pipe (chemical feed pipe), and residual air easily enters blood of human body, cause the possibility of air embolism, helmet is pulled out aerofluxus easily cause the liquid waste.Stipulate according to Chinese Pharmacopoeia, " intravenous drip is with insoluble microparticle in the injection; containing the above microgranule of 10um among every ml must not be above 20; containing the above microgranule of 25um must not be above two " adopts this direct method to patient's injection liquid, insoluble microparticle in the medicinal liquid, wherein the above microgranule of 10um has surpassed 23-48 doubly, has caused great infringement to human body.
Summary of the invention
This utility model overcomes weak point of the prior art, has solved the filtration problem of injecting liquid when giving emergency treatment to a patient and a kind of valve-type tee T transfusion device that the valve-type tee T is contained in ultimate filter upper end is provided.
This utility model is to realize like this, valve-type tee T transfusion device, include the syringe needle that disposable transfusion device is equipped with, exhaustor, the Mo Feishi dropper, minim pipette, actuator, filter, it is characterized in that an end of valve-type tee T is contained in the upper end of ultimate filter, the other end links to each other with minim pipette, the valve-type tee T is contained in the ultimate filter upper end, both two kinds of liquid of infusion simultaneously, can in transfusion, directly push other medicines in patient's vein by pencil again, and the every operation process is all carried out under full closeding state, prevent effectively in the air admission blood of human body, main is to have solved the filtration problem of injecting liquid when giving emergency treatment to a patient, and has reduced particle contamination.
This utility model compared with prior art has the saving medicinal liquid, reduces particle contamination, and advantage such as increase work efficiency is applicable to give emergency treatment to a patient and the surgery anesthesia patient uses to have certain popularization value.
