Abstract
The utility model relates to an infusion set capable of preventing blood from reflowing. The upper end of the infusion set is connected with an infusion packing body through an infusion tube; the lower end of the infusion set is connected with an infusion needle through the infusion tube; the infusion set capable of preventing blood from reflowing consists of a liquid inlet at an upper end, a flow stopping cabin below the liquid inlet, a valve ball cabin at a middle end, a flow stopping valve ball in the valve ball cabin, a support below the flow stopping valve ball and a liquid outlet at a lower end in sequence from top to bottom; the flow stopping cabin is a horn mouth of which the upper part is small and the lower part is large; the valve ball cabin is a section of pipeline in which the flow stopping valve ball is suspended; the flow stopping valve ball is a sphere of which the diameter is smaller than that of the valve ball cabin and is greater than that of the liquid inlet; the support is a screen arranged at the lower section of the valve ball cabin; and the support is a cone or has a positive cone structure. After infusion is finished, the flow stopping valve ball is suspended in the valve ball cabin, and a backflow liquid medicament pushes the suspended flow stopping valve ball to the horn mouth of the flow stopping cabin during blood reflow, so that an infusion pipeline is blocked, and the phenomenon of blood reflowing is avoided.
Description
Technical field
This utility model relates to the infusion set in the medical apparatus and instruments, the bag transfusion system that particularly resistant to blood refluxes in infusion process.
Background technology
In infusion process; The transfusion package body is pressed into medicinal liquid through gravity and atmospheric pressure the vein of human body; But after the intravital medicinal liquid of transfusion package is totally lost; Its atmospheric pressure and medicinal liquid gravity just do not exist infusion pipeline to suffer, and at this moment the intravital blood pressure of people just can cause the blood back phenomenon with blood reflux in flowing into infusion pipeline.Hospital often has a lot of patients to infuse simultaneously, sometimes is very busy of medical personnel of patient infusion, after medicinal liquid is totally lost, does not in time handle, and causes blood back.This existing picture never has the very low and effective way of a kind of cost and solves, often behind blood back, let the patient of not clear situation see after, psychology produces panic, influence is sought medical advice and patient health.The existence of this blood back phenomenon mainly is because after transfusion is accomplished, under the situation that does not have again in time to handle, do not let infusion pipeline be in dissengaged positions automatically, and caused blood back.
The utility model content
It is a kind of in infusion process that the purpose of this utility model is to provide, and can not produce the bag transfusion system of the resistant to blood backflow of blood back phenomenon.
This utility model is following: resistant to blood backflow transfusion device; Be arranged in the infusion pipeline; Its upper end is connected with the transfusion package body through tube for transfusion, and the lower end is connected with transfusion needle through tube for transfusion, and resistant to blood backflow transfusion device has the inlet of upper end, the fluid stopping storehouse under it from top to bottom successively; The valve ball storehouse of middle-end, the fluid stopping valve ball in the valve ball storehouse, the bearing under it, the liquid outlet of lower end; Described fluid stopping storehouse is up-small and down-big horn mouth, and the valve ball storehouse is one section pipeline, and inner suspension has the fluid stopping valve ball; The fluid stopping valve ball is a spheroid, and diameter is less than the valve ball storehouse and greater than inlet, and described bearing is the screen cloth that is arranged on valve ball storehouse hypomere, and described bearing is a cone, is positive taper.
As above closely state, illustrate further into, inlet to the distance of liquid outlet less than 3 times of valve ball diameter.
This utility model effect is following: after transfusion was accomplished, the intravital blood pressure of people was greater than the medicinal liquid pressure in the infusion pipeline, and blood begins to reflux in tube for transfusion.Because the fluid stopping valve ball is suspended in the valve ball storehouse; When blood refluxed, the medicinal liquid in the valve ball storehouse also began to flow backwards the fluid stopping valve ball that the medicinal liquid of refluence will certainly promote to suspend; And the fluid stopping valve ball pushed to the horn mouth in fluid stopping storehouse; Thereby the fluid stopping ball valve just blocks the horn mouth in fluid stopping storehouse, has also just blocked infusion pipeline, has prevented the generation of blood back phenomenon.
Bearing is positive conical design, after the fluid stopping valve ball sinks, can not stop normal infusion process.
Description of drawings
Fig. 1 is that this utility model uses sketch map;
Fig. 2 is the structure chart of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Press this utility model resistant to blood backflow transfusion device among Fig. 2; Its upper end is connected with transfusion package body 1 through tube for transfusion; The lower end is connected with transfusion needle 6 through tube for transfusion; Resistant to blood backflow transfusion device has the inlet 2 of upper end, the fluid stopping storehouse 3 under it from top to bottom successively, fluid stopping valve ball 8, the bearing under it 4 in the valve ball storehouse 9 of middle-end, the valve ball storehouse 9, the liquid outlet 7 of lower end; Described fluid stopping storehouse 3 is up-small and down-big horn mouth, and valve ball storehouse 9 is one section pipeline, and inner suspension has fluid stopping valve ball 8; Fluid stopping valve ball 8 is a spheroid, and diameter is less than the valve ball storehouse and greater than inlet, and described bearing 4 is for being arranged on the screen cloth of valve ball storehouse hypomere.Described bearing 4 is a cone, is positive taper.
In use, press this programme setting,, include fluid stopping device 5, the infusion needle 6 of transfusion package body 1, this utility model in the infusion pipeline successively like Fig. 1; In infusion process; Medicinal liquid is for flowing from the top down, in the valve ball storehouse 9 fluid stopping valve ball 8 by the mobile strength band of medicinal liquid on bearing 4 screen clothes of bottom, after transfusion is accomplished; The intravital blood pressure of people is greater than the medicinal liquid pressure in the infusion pipeline, and blood begins to reflux in tube for transfusion.Because fluid stopping valve ball 8 is suspended in the valve ball storehouse 9; When blood refluxed, the medicinal liquid in the valve ball storehouse 9 also began to flow backwards the fluid stopping valve ball 8 that the medicinal liquid of refluence will certainly promote to suspend; And fluid stopping valve ball 8 pushed to the horn mouth in fluid stopping storehouse 3; Thereby fluid stopping ball valve 8 just blocks the horn mouth in fluid stopping storehouse 3, has also just blocked infusion pipeline, has prevented the generation of blood back phenomenon.
Combined accompanying drawing that the specific embodiment of this utility model has been carried out exemplary description above, obviously this utility model is not limited thereto, and the various remodeling that in this utility model scope, carry out all do not exceed the protection domain of this utility model.
