Abstract
The utility model relates to a backflow-proof blood drop speed display tube and belongs to the technical field of medical equipment. Two ends of a drop speed display tube are movably connected with an infusion tube; the infusion tube at one end is connected with an injection syringe needle; the drop speed display tube is internally provided with a floating block and the outer diameter of the floating block is less than the inner diameter of the blood drop speed display tube; and a liquid output end of the drop speed display tube is in a funnel shape. When the backflow-proof blood drop speed display tube is used, the floating block in the drop speed display tube is floated along the entering of liquid medicine, so that the drop speed display is not influenced; after the liquid medicine is infused, the floating block is moved downwards to an output end of the drop speed display tube and an outlet of the drop speed display tube is sealed; and a vein pressure of a patient can be overcome by utilizing a pressure of the residual liquid medicine in the infusion tube below the output end of the drop speed display tube, so that the aim of preventing blood of a vein from being flowed back is achieved. The backflow-proof blood drop speed display tube has the advantages of simple structure and strong practical applicability, and is suitable for a vertical infusion method which is commonly used at present.
Description
One, technical field:
This utility model relates to a kind of blood return prevention drop speed display tube that is used to carry medicinal liquid, belongs to technical field of medical instruments.
Two, background technology:
Venous transfusion is the treatment means that each medical institutions uses always the disease patient, and medicinal liquid is through tube for transfusion, drop speed display tube, syringe needle input human vein, to reach therapeutic purposes during transfusion; Yet in practical operation; Because the medical worker is for the moment busy or forget, and the patient loses consciousness " deep sound sleep " can't call the time, after medicinal liquid is totally lost, can not in time extract injection needle; Cause patient's vein blood back thus, and produce inconvenience and problem therefrom.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of can prevent the blood return prevention drop speed display tube of patient's vein blood back from movable sealing drop speed display tube delivery outlet after medicinal liquid is totally lost.
This utility model is realized through following technical scheme: the blood return prevention drop speed display tube includes drop speed display tube; The drop speed display tube two ends all flexibly connect 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 the 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 a funnel-form.
After adopting such structure; The interior floating block of drop speed display tube can get into medicinal liquid and float, and does not influence and drips the speed demonstration, and floating block was displaced downwardly to the drop speed display tube outfan again after medicinal liquid was totally lost; And sealing drop speed display tube delivery outlet; Utilize the pressure of the interior residual liquor of 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.
This utility model 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 sketch map of this utility model;
Accompanying drawing 2 is another user mode sketch map of this utility model.
Five, the specific embodiment:
Like accompanying drawing 1,2; This utility model includes drop speed display tube 1; Drop speed display tube 1 two ends all flexibly connect with tube for transfusion 2, and wherein the tube for transfusion 2 of lower end connects injection needle, is provided with a circular cone cylindricality floating block 3 in the 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 a funnel-form.
When medicinal liquid got into drop speed display tubes 1 by tube for transfusion 2, circular cone cylindricality floating block 3 floated with medicinal liquid, did not influence this moment to drip speed and show; 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 residual medicinal liquid pressure in the drop speed display tube 1 below tube for transfusion 2, overcome patient's vein pressure, reach the purpose that prevents blood back.
This utility model is simple in structure, and is practical, is applicable to the vertical infusion method that generally uses now.
