Abstract
The present invention discloses a transfusion drip tube which wants to solve the technical problem that air in a drip tube is automatically discharged. A drip tube body of the transfusion drip tube is a conical or calabash body structure. A small outlet tube of which the length is one second to two thirds than the height of the drip tube body is arranged in the drip tube body. The small outlet tube is inserted into the drip tube body from the lower end of the drip tube body, and is in a through hole shape. The top part of the small outlet tube is sealed. A hole is arranged on the tube wall of the small outlet tube between one mm from the top part of the small outlet tube to the height of one second to three fifths of the small outlet tube. Compared with the prior art, the transfusion drip tube uses the conical or calabash body structure; liquid level is controlled at three fifths of the drip tube; the small outlet tube is arranged in the transfusion drip tube; liquid medicine passes through a round hole or long groove on the small outlet tube under the function of gravity to discharge the air, the extrusion for the transfusion drip tube is not needed, so labor liquid level adjusting progress before transfusion is reduced, the simple and fast effect is obtained, and the safety of transfusion is ensured.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.As shown in Figure 1, transfusion drip tube of the present invention has dropper body 1; Adopt medical transparent elastic material, the two ends of dropper body 1 connect the elasticity tube for transfusion, and said dropper body 1 is a conical structure; Up-small and down-big, also can be or the calabash body structure that the bottom of conical structure is a hemispherical dome structure 2; Being provided with length in the dropper body 1 is the little outlet pipe 3 of dropper body 1 height h 1/2nd to 2/3rds; Said little outlet pipe 3 inserts in the dropper body 1 from the lower end of dropper body 1, and said little outlet pipe 3 is the through hole shape, and the top is an enclosed construction; The bottom of little outlet pipe 3 connects the elasticity tube for transfusion of bottom; On the tube wall of little outlet pipe 3, have hole 4, hole 4 is located at little outlet pipe 3 between top 1mm is down to dropper height 1/2nd to 3/5ths places, is preferably hole 4 and is located at little outlet pipe 3 between top 1mm is down to dropper height 1/2nd places.
The overall dimensions of dropper body 1 of the present invention is: upper diameter D1 is 14 to 16mm, and lower diameter D2 is 18 to 20mm, and height h is 45mm to 60mm, and being preferably upper diameter D1 is 15.5mm, and lower diameter D2 is 20mm, and height h is 55mm.
The height of little outlet pipe 3 of the present invention is 31 to 35mm, and internal diameter is 2.5 to 2.8mm, and preferred heights is 33mm, and internal diameter is 2.5mm.
As shown in Figure 2, said hole 4 is an elongated slot, and said elongated slot has two to three, is preferably three, and the length dimension of elongated slot is consistent with the axis direction of little outlet pipe 3, is evenly distributed on the tube wall of little outlet pipe 3.Said elongated slot length is 18mm to 20mm, and width is 0.4mm to 0.6mm, and preferred elongated slot length is 19mm, and width is 0.5.
As shown in Figure 3, said hole 4 is a circular hole, is arranged in a linear at interval, and the straight line that arrange in the hole is consistent with the axis direction of little outlet pipe 3, is two to three rows, is preferably three rows, is evenly distributed on the tube wall of little outlet pipe 3.Spacing between the hole heart of every row's circular hole is 1.0mm to 1.2mm, is preferably 1.0mm.The diameter of said circular hole is 0.4mm to 0.6mm, is preferably 0.6mm.
Before the transfusion, the elasticity tube for transfusion that connects dropper body 1 upper end is communicated with medicine bottle, medicinal liquid begins to get into dropper body 1 along the elasticity tube for transfusion; After medicinal liquid got into dropper body 1, liquid level can rise along body, up to the top of liquid level to little outlet pipe 3; Under the effect of liquid gravity and pressure,, and discharge from the elasticity tube for transfusion with the elasticity tube for transfusion of the air in the dropper body 1 through the 4 entering lower ends, hole on little outlet pipe 3 tube walls; Arrive the elasticity tube for transfusion lower end syringe needle that connects dropper body 1 bottom until medicinal liquid, thoroughly arranged air, at this moment the aqueous vapor volume ratio of dropper body 1 internal volume is 3: 1; The medicinal liquid plane is at the position, 3/5ths places of dropper body 1 (by the extension elongation decision liquid level of little outlet pipe 3); Can begin the transfusion to the patient, dropper body 1 of the present invention is cone or calabash body structure, when 1 inclination of dropper body, prosposition or handstand position; The elasticity tube for transfusion that does not all have air admission dropper body 1 bottom has guaranteed the safety of infusing.
As shown in Figure 4, when dropper body 1 vertical the placement, liquid level and little outlet pipe are 90 degree angles, and little outlet pipe is all in liquid.
As shown in Figure 5, when dropper body 1 tilted to place, liquid level became 45 ° of angles with little outlet pipe, and little outlet pipe is all in liquid.
As shown in Figure 6, when dropper body 1 horizontal positioned, liquid level is parallel with little outlet pipe, and little outlet pipe is all in liquid.
As shown in Figure 7, when dropper body 1 stood upside down placement, liquid level and little outlet pipe were inverted, and little outlet pipe is all in liquid.
Transfusion drip tube of the present invention is simple in structure, has two big clear superiorities: 1. when moving transfusion person, when the dropper inclination takes place, avoid occurring the danger of air admission human body, guaranteed the safety of transfusion; 2. remove from and adopt the prior art tube for transfusion to need the planar program of artificial adjustment liquid, reach effect easily and efficiently, improved the efficient of nurse's work.
