Abstract
The utility model relates to the technical field of the medical appliance, in particular to a deep vein puncture needle which can judge artery and vein. The deep vein puncture needle which can judge artery and vein comprises a vain puncture needle, which is characterized in that a rotary slide valve and a side outlet three-way pipe are arranged on the needle tail of the vein puncture needle. The utility model has the advantages of simple structure, low cost and convenient employment.
Description
Technical field
This utility model relates to technical field of medical instruments, and a kind of specifically energy is judged arteriovenous deep vein puncture pin.
Background technology
Because the normal companion mutually of deep tremulous pulse and vein row in the deep vein puncture process, is strayed into tremulous pulse sometimes.Mostly be at present to disconnect and judge arteriovenous according to pumpback blood color or with syringe and deep vein puncture pin.Redder as the blood color is tremulous pulse, and color more secretly is a vein; What blood was gushed after syringe and deep vein puncture pin disconnected is tremulous pulse, otherwise is vein.Yet some patient is low as arterial oxygen saturation, some exists right-left shunt congenital heart disease, arterial blood to force down or the venous pressure height, often is difficult to judge according to these experimental standards.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, can accurately judge arteriovenous deep vein puncture pin and provide a kind of.
The technical solution of the utility model is achieved in that can judge arteriovenous deep vein puncture pin, comprises venipuncture needle, it is characterized in that: the venipuncture needle backshank adds a tee T that guiding valve and side mouth are arranged.
The utlity model has simple in structure, with low cost, easy to use.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
Can judge arteriovenous deep vein puncture pin, comprise venipuncture needle (1), it is characterized in that: venipuncture needle (1) backshank adds a tee T that revolving valve (3) and side mouth (2) are arranged.
Side mouth (2) connects the general infusion set that sequences liquid during use, revolving valve (3) is rotated to the position that side mouth (2) is closed, when blood is seen in the puncture pumpback, revolving valve (3) is rotated to the position that blood vessel communicates with transfusion device, if tremulous pulse, then liquid can not splash into, and has blood to reflux, and the blood liquid level fluctuates up and down.
Claims (1)
1. can judge arteriovenous deep vein puncture pin, comprise venipuncture needle (1), it is characterized in that: venipuncture needle (1) backshank adds a tee T that revolving valve (3) and side mouth (2) are arranged.
