Abstract
The invention relates to a blood return resistant dripping speed display tube used for delivering liquid medicine and belongs to the technical field of medical apparatus. The two ends of the dripping speed display tube are both movably connected with infusion tubes, the infusion tube at one end is connected with an injection needle, a floating block is arranged in the dripping speed display tube, the outer diameter of the floating block is smaller than the inner diameter of the dripping speed display tube, and the liquid output end of the dripping speed display tube is funnel-shaped. When the blood return resistant dripping speed display tube is used, the floating block in the dripping speed display tube can float along with the entering of the liquid medicine, the display of dripping speed is not affected, after the liquid medicine infusion is finished, the floating block shifts down to the output end of the dripping speed display tube and seals the output port of the dripping speed display tube, the pressure of liquid medicine remained in the infusion tube below the output end of the dripping speed display tube is used for overcoming the vein pressure of a patient, and thus the purpose of avoiding vein blood return is achieved. The blood return resistant dripping speed display tube is simple in structure, strong in practicality and applicable to a vertical infusion method generally used at present.
Description
One, technical field:
The present invention relates to a kind of drop speed showing tube with blood return prevention for delivery of medicinal liquid, belong to technical field of medical instruments.
Two, background technology:
Venous transfusion is that each medical institutions are to Disease treatment means commonly used, during transfusion, medicinal liquid is by tube for transfusion, drop speed display tube, syringe needle input human vein, to reach therapeutic purposes, yet in practical operation, because the medical worker is for the moment busy or forget, and the confused " deep sound sleep " of patient can not in time be extracted injection needle can't call the time after medicinal liquid is totally lost, cause thus patient's vein blood back, and produce therefrom inconvenience and problem.
Three, summary of the invention:
But the object of the present invention is to provide a kind of after medicinal liquid is totally lost automatic-sealed drop speed display tube delivery outlet, prevent the drop speed showing tube with blood return prevention of patient's vein blood back.
The present invention is achieved through the following technical solutions: drop speed showing tube with blood return prevention includes drop speed display tube, the drop speed display tube two ends all are flexibly connected with tube for transfusion, wherein the tube for transfusion of an end connects injection needle, be provided with a circular cone cylindricality floating block in drop speed display tube, the external diameter of floating block is less than the internal diameter of drop speed display tube, and the liquid outfan of drop speed display tube is funnel-form.
After adopting such structure, floating block in drop speed display tube can enter and floats with medicinal liquid, do not affect and drip the speed demonstration, the medicinal liquid rear floating block of being totally lost is displaced downwardly to again the drop speed display tube outfan, and sealing drop speed display tube delivery outlet, utilize the pressure of residual liquor in the tube for transfusion of drop speed display tube outfan below, overcome patient's vein pressure, thereby reach the effect that prevents the vein blood back.
The present invention is simple in structure, and is practical, is applicable to the vertical infusion method that generally uses now.
Four, description of drawings:
Accompanying drawing 1 is a user mode schematic diagram of the present invention;
Accompanying drawing 2 is another user mode schematic diagram of the present invention.
Five, the specific embodiment:
As accompanying drawing 1,2, the present invention includes drop speed display tube 1, drop speed display tube 1 two ends all are flexibly connected with tube for transfusion 2, wherein the tube for transfusion 2 of lower end connects injection needle, be provided with a circular cone cylindricality floating block 3 in drop speed display tube 1, the external diameter of floating block 3 is less than the internal diameter of drop speed display tube 1, and the liquid outfan 4 of drop speed display tube 1 is funnel-form.
When medicinal liquid entered drop speed display tube 1 by tube for transfusion 2, circular cone cylindricality floating block 3 floated with medicinal liquid, did not affect this moment to drip the speed demonstration; When medicinal liquid is about to be totally lost, the lower bottom part that medicinal liquid drops to drop speed display tube 1 simultaneously, floating block 3 also descends with medicinal liquid, and stops up its output port of sealing at the lower bottom part of drop speed display tube 1.At this moment, utilize the interior residual medicinal liquid pressure of drop speed display tube 1 below tube for transfusion 2, overcome patient's vein pressure, reach the purpose of anti-return blood.
The present invention is simple in structure, and is practical, is applicable to the vertical infusion method that generally uses now.
