Abstract
The utility model relates to a medical appliance, in particular to a liquid-stopping intravenous transfusion apparatus capable of preventing blood backflow. The liquid-stopping intravenous transfusion apparatus comprises a burette, an upper transfusion catheter and a lower transfusion catheter, and the upper transfusion catheter and the lower transfusion catheter extend into the burette. The liquid-stopping intravenous transfusion apparatus is characterized in that a sheet is covered at an end of the lower transfusion catheter in the burette, and the other end of the sheet is hinged on the outer wall of the lower transfusion catheter. The liquid-stopping intravenous transfusion apparatus can prevent blood from flowing back to the transfusion catheters, after transfusion is completed or transfusion height is not enough, the sheet can seal a liquid inlet end of the lower transfusion catheter, the lower transfusion catheter is closed in time so as to be capable of preventing air from entering a blood vessel of a patient, and simultaneously, venous pressure is balanced with pressure in the lower transfusion catheter so as to prevent backflow of the blood.
Description
Technical field
This utility model relates to a kind of medical equipment, specifically a kind of solution stopping intravenous transfusion device that can prevent blood back.
Background technology
Present known medical Transfusion device is that infusion bottle is uphang on support, presses to guarantee certain high position, and the messenger drug liquid stream is gone in the body, simultaneously, keeps balance in order to keep pressure of the inside of a bottle with the outer air pressure of bottle, and air gets into infusion bottle from air inlet needle and air inlet pipe.The transfusion device of this structure; If it is improper to nurse, when medicinal liquid was totally lost, the tube for transfusion internal pressure was lower than human vein and presses; Just having blood flow goes in the tube for transfusion; Cause blood back, blood back not only can cause conduit because air embolism and can't continue transfusion, even causes blood coagulation to become clot and to serious problems such as human body damage.
Summary of the invention
The purpose of this utility model provides a kind of solution stopping intravenous transfusion device that can in time close tube for transfusion, prevent to produce negative pressure.
This utility model is that the technical scheme that the technical solution problem is adopted is:
The solution stopping intravenous transfusion device; Comprise burette, extend to top transfusion catheter and bottom transfusion catheter in the burette; It is characterized in that: the end that is positioned at the bottom transfusion catheter of burette is provided with thin slice, and the area of thin slice is greater than the inlet area of bottom transfusion catheter.
One end of said thin slice is fixedly connected buoyancy aid, and said buoyancy aid is the closed shell of hollow, and the other end of said thin plate is hinged on the tube for transfusion outer wall of below.
Owing to adopted said structure; The described solution stopping intravenous transfusion device of this utility model is simple in structure, production cost is low, and when transfusion finished, thin slice can be sealed the liquid feeding end of transfusion catheter; Prevent to produce negative pressure; Can prevent the air admission blood vessel, make venous pressure and tube for transfusion internal pressure balance simultaneously, prevent that blood from refluxing.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the A portion partial enlarged drawing of Fig. 1.
Fig. 3 is the structure vertical view of the described sheet segment of this utility model.
The specific embodiment
As shown in the figure, the described solution stopping intravenous transfusion device of this utility model comprises burette 1, extends to top transfusion catheter 2 and bottom transfusion catheter 3 in the burette 1; The end that is positioned at the bottom transfusion catheter 3 of burette 2 is provided with thin slice 4, and the area of thin slice 4 is greater than the inlet area of bottom transfusion catheter 3, and described thin slice 4 one ends are fixedly connected buoyancy aid 5; Said buoyancy aid 5 is the closed shell of hollow, and is filled with the gas of density less than transfusion liquid in the buoyancy aid 5, and the other end of said thin plate 4 is hinged on tube for transfusion 3 outer walls of below; Be fixedly connected the support 7 that has axle 6 on the outer wall of said bottom transfusion catheter 3, the hinged end of said thin plate 4 is provided with axle sleeve 8, and said axle 6 passes axle sleeve 8; During transfusion, along with the minimizing of medicinal liquid, buoyancy aid 5 constantly descends; Up to the inlet sealing of thin slice 4, when transfusion finishes, can prevent the air admission transfusion catheter with bottom transfusion catheter 3; Keep tube for transfusion pressure and venous pressure balance, prevent blood back.
Claims (2)
