Abstract
The utility model relates to a safety transfusion tube, comprising an upper liquid flow tube, a lower liquid flow tube, a transfusion speed display and a speed regulation clamp. Both ends of the transfusion speed display are provided with plugs; the upper liquid flow tube and the lower liquid flow tube are inserted on the transfusion speed display; a float is arranged in the transfusion speed display. The utility model can not influence the normal infusion but can prevent the blood returning phenomenon happening after the transfusion and can prevent the air being led into the body.
Description
The utility model relates to a kind of infusion set.
The one-time infusion tube of in medical treatment, using now be by on liquid flow duct, liquid flow duct, transfusion speed display down, speed adjustable clamps etc. are partly formed.The two ends of transfusion speed display all have plug, and the liquid flow pipe is inserted on the transfusion speed display up and down, and on the moving pipe of speed adjustable clamp cover infra liquid stream, last liquid flow duct links to each other with the plug of bringing trachea into, and following liquid flow pipe links to each other with syringe needle.Before transfusion finishes, must in time tube for transfusion be pulled up, otherwise will produce blood back or air be imported abnormality such as blood vessel, influence the healthy of people.Therefore adopt this tube for transfusion, medical personnel must observe transfusion state at any time.
The purpose of this utility model is to provide a kind of safe transfusion tube that can prevent backflow of blood effectively or import air.
The purpose of this utility model is achieved in that it comprises liquid flow pipe, following liquid flow pipe, transfusion speed display and speed adjustable clamp, transfusion speed display two ends all have plug, upper and lower liquid flow pipe is inserted on the transfusion speed display, is provided with a float in the transfusion speed display.
Advantage of the present utility model is: be provided with float in the transfusion speed display; when the protection of the liquid level in transfusion speed display certain height; float floats on the liquid level; keep the normal infusion state; after the liquid in the infusion bottle was totally lost, after the liquid level in the transfusion speed display dropped to outlet, float blocked up in exporting down; make down the liquid in the liquid flow pipe stop to flow, play and prevent blood back, prevent in body, to import the purpose of air.The float shape can design according to the shape that the transfusion speed display exports down.The internal diameter of the last plug of transfusion speed display can be designed to bigger than the internal diameter of following plug, so that float is successfully packed in the transfusion speed display.Of the present utility model simple in structure, easy to use, safe and reliable.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 to Fig. 6 is difform Floater Structure sketch map.
For example this utility model is done more detailed description below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the composition of safe transfusion tube comprises liquid flow duct 1, following liquid flow duct 2, transfusion speed display 3, float 4.The upper/lower terminal of transfusion speed display has plug 5,6, and upper and lower liquid flow pipe is inserted in respectively on the plug up and down of transfusion speed display, and float places in the transfusion speed display, is with speed adjustable clamp 7 on the infra liquid flow pipe.For the ease of the installation of float, the internal diameter of the last plug of transfusion speed display is greater than the internal diameter of following plug.In conjunction with Fig. 2, float is conical.In conjunction with Fig. 3, float is a truncated cone-shaped.In conjunction with Fig. 4, float is spherical.In conjunction with Fig. 5, float is a hemispherical.In conjunction with Fig. 6, float is a semielliptical shape.Float can be a solid, also can be hollow body.
