Abstract
The utility model discloses an anti-blood return transfusion tube, which comprises a drip cup and transfusion pipelines connected to the two ends of the drip cup, and is characterized in that: a spheroidal buoy which is made of an elastic material and floats on a liquid medicament is arranged in the drip cup; and the bottom of the drip cup is circular-arc-shaped. The anti-blood return transfusion tube can be used for effectively preventing blood return, is simple in structure, is very convenient to manufacture and use, and is very low in manufacturing cost.
Description
Technical field
This utility model relates to medical instruments, specifically a kind of tube for transfusion that in infusion process, can prevent blood back.
Background technology
Necessary when tube for transfusion is patient infusion uses very extensive in hospital.At present; The common transfusion Guan Junwei that uses in hospital takes any blood back measure; Must in time tell medical personnel to pull out pin when the medicinal liquid in the tube for transfusion will be use up, perhaps send special medical personnel to guard patient, thereby otherwise just very easily cause blood to pass back in the tube for transfusion because the pipe inner liquid medicine causes medicinal liquid pressure to be lower than vein blood vessel pressure very little; Be " blood back " that people are commonly called as, even might therefore cause the generation of great malpractice.
Cause the situation of " blood back " to the existing utmost point of common transfusion pipe; Also there is the people this to be carried out improvement; Utility model patent " tube for transfusion of the blood return prevention " (patent No.: 2007200932815) such as Liu Zilin; This kind tube for transfusion is that in dripping kettle, to add a magnetic cursory; Install a Magnet additional in the outside, bottom of dripping kettle again, when the medicinal liquid in dripping kettle will be use up, thereby thereby utilize the magnetic field principle that there is a natural attraction between the sexes that the cursory medicine liquid outlet that will drip the kettle bottom in the bottom of dripping kettle of inhaling of magnetic is stopped up and prevents that medicinal liquid from using up fully and cause " blood back ".Though the tube for transfusion after this kind improvement can effectively prevent " blood back ", its cost cost is higher relatively, the machining process more complicated; And use and very inconvenience of operation, therefore, be difficult to apply on a large scale; Simultaneously; Because the cursory hard material that is that adopts is processed, itself and seal that drips the kettle outlet at bottom and bad cause leakage easily and can not fundamentally prevent " blood back ".
The utility model content
It is a kind of simple in structure that this utility model is to provide, and the cost cost is low, uses and the easy to operate tube for transfusion that can effectively prevent blood back, to solve the shortcoming and deficiency in the above-mentioned background technology.
The technical problem that this utility model solved adopts following technical scheme to realize:
The blood return prevention tube for transfusion comprises and drips kettle and be connected the liquid-transport pipe-line that drips the kettle two ends, it is characterized in that it is cursory in dripping kettle, to be provided with a spheroidal that processed by elastomeric material, that can float on the medicinal liquid face; Seal when combining bottom dripping kettle in order to guarantee that spheroidal is cursory, the bottom of said kettle is a circular arc.
Operation principle: when in dripping kettle, medicinal liquid being arranged, circular cursory floating on the medicinal liquid, tube for transfusion can normally use; Use up when dripping the kettle inner liquid medicine; Medicinal liquid drops to when dripping the kettle turbination below liquid-transport pipe-line mouth of pipe; Circle is cursory to fall to the liquid-transport pipe-line mouth of pipe in action of gravity thereupon; And gravity and below under the suction of liquid-transport pipe-line inner liquid medicine, prevent that medicinal liquid is dirty and finally cause " blood back " thereby the mouth of pipe of below liquid-transport pipe-line firmly blocked; After in dripping kettle, being full of medicinal liquid again, circular cursory buoyancy float downward at medicinal liquid, the below liquid-transport pipe-line mouth of pipe is opened, and it is normal that transfusion recovers.
Beneficial effect: this utility model can effectively prevent blood back, and simple in structure, manufacturing and extremely easy to use, the cost cost is extremely low.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: it is cursory that 1-drips kettle 2-liquid-transport pipe-line 3--spheroidal
The specific embodiment
Specify as follows below in conjunction with the specific embodiment of accompanying drawing this utility model:
Referring to shown in Figure 1; The blood return prevention tube for transfusion comprises and drips kettle 1 and be connected the liquid-transport pipe-line 2 that drips the kettle two ends, it is characterized in that; In dripping kettle 1 be provided with one that process by elastomeric material, to float on spheroidal on the medicinal liquid cursory 3, the bottom of said kettle is a circular arc
During production, circular arc is processed in the bottom of dripping kettle, and it is cursory in dripping kettle, to put into a circle, the upper/lower terminal that will drip kettle again connects the upper tubing road and gets final product.
When transfusion, dripping in the kettle has medicinal liquid, and circular cursory because of its proportion floats on the medicinal liquid less than medicinal liquid, tube for transfusion can normally use; Use up when dripping the kettle inner liquid medicine; Medicinal liquid drops to when dripping the kettle circular arc-shaped bottom portion liquid-transport pipe-line mouth of pipe; Circle is cursory to fall to the liquid-transport pipe-line mouth of pipe in action of gravity thereupon; And gravity and below under the suction of liquid-transport pipe-line inner liquid medicine, prevent that medicinal liquid is dirty and finally cause " blood back " that the circular arc design of dripping the kettle bottom has ensured circularly cursoryly can be fallen the bottommost that drips kettle and be connected closely with the mouth of pipe thereby the mouth of pipe of below liquid-transport pipe-line firmly blocked; After in dripping kettle, being full of medicinal liquid again, circular cursory the below liquid-transport pipe-line mouth of pipe is opened then at the buoyancy float downward of medicinal liquid, and it is normal that transfusion recovers.
