Abstract
The utility model discloses a disposable vacuum blood collection tube, which comprises a transparent tube body and a seal plug, wherein one end of the tube body is sealed, and the other end thereof is provided with an opening; the external circumference surface of the seal plug is provided with an annular groove; and a hollow thin-wall rubber ring filled with the air inside is arranged in the groove. In the utility model, the volume of the hollow thin-wall rubber ring in the tube can be directly observed from the outside the tube; whether the negative pressure in the tube allows the tube to be available or not can be clearly and simply known according to the volume change by combining a lower limit scale mark, and if the tube cannot be used, the tube needs to be changed only, and whether the tube is available or not can be known before the blood collection.
Description
Technical field:
This utility model relates to technical field of medical instruments, relates to a kind of vacuum test tube that is used for gathering blood in particular.
Background technology:
Vacuum test tube is to be applied to clinical check blood sampling new product in recent years.It utilizes the intravital negative pressure of vacuum of pipe to draw blood, because it is easy and simple to handle, clean safe, accurately and reliably, is each hospital's widespread usage.But in clinical use, find that it also has various weak points, influenced the smooth collection of specimen.Its weak point exists:
Blood flows into not smooth, could gather blood smoothly because will keep certain negative pressure of vacuum in the blood taking tube, but placing for a long time makes a spot of air enter between pipe close and body, make the body decompression, and do not see whether decompression of blood taking tube when in use from the outside, just know when can only use.Cause the seldom less even inflow of inflow of blood, cause the blood sampling volume deficiency, then need to change blood taking tube and gather again, lose time, reduced the efficient of work, also increased nurse's workload, more increased patient's misery;
Therefore need a kind of whether available vacuum test tube of negative pressure of vacuum of can discerning in the blood taking tube.
The utility model content:
The purpose of this utility model is to provide a kind of disposal vacuum blood taking tube at the deficiencies in the prior art part, can overcome the deficiencies in the prior art part, it is filled with the hollow thin-wall rubber ring of air by the inside that is provided with on sealing-plug, whether can discern in the blood taking tube negative pressure of vacuum available.
Technology solution of the present utility model is as follows:
The disposal vacuum blood taking tube comprises transparent body, sealing-plug, described body one end sealing, the other end has opening, described sealing-plug is fixed on this opening, has annular groove on the outer circumference surface of sealing-plug, and the hollow thin-wall rubber ring that inside is filled with air is installed in this groove.
Described disposal vacuum blood taking tube, the wall thickness of described hollow thin-wall rubber ring are 0.03～0.05 millimeter.
Described disposal vacuum blood taking tube, with the outer surface of the corresponding body of described annular groove on be provided with the lower limit scale mark.
Described disposal vacuum blood taking tube forms the hole that communicates with described annular groove on the lower surface of described sealing-plug.
Described disposal vacuum blood taking tube, described hollow thin-wall rubber ring is made by the nitrile rubber of redness.
Described disposal vacuum blood taking tube, described body is provided with over cap.
This utility model beneficial effect is:
1) this utility model can be in the direct observation pipe of the outside of pipe the volume of hollow thin-wall rubber ring, variation according to its volume just can know in conjunction with the lower limit scale mark whether the negative pressure of simply knowing in the pipe can used again, if could use only need change one all right, just can know whether handy after needn't taking a blood sample by the time.
2) employing of hollow thin-wall rubber ring has increased sealing, makes that the sealing between sealing-plug and the body is tightr, in the extraneous air body more difficult to get access, and the intravital negative pressure of vacuum of holding tube for a long time.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is described further:

The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1～2: the disposal vacuum blood taking tube, comprise transparent body 1, sealing-plug 2, described body 1 one ends sealing, the other end has opening 101, described sealing-plug 2 is fixed on this opening 101, have annular groove 201 on the outer circumference surface of sealing-plug 2, the hollow thin-wall rubber ring 3 that inside is filled with air is installed in this groove 201.
The wall thickness of described hollow thin-wall rubber ring 3 is 0.03～0.05 millimeter.
With the outer surface of described annular groove 201 corresponding bodys 1 on be provided with lower limit scale mark 4.
Form the hole 203 that communicates with described annular groove 201 on the lower surface 202 of described sealing-plug 2.
Described hollow thin-wall rubber ring 3 is made by the nitrile rubber of redness.Red color makes hollow thin-wall rubber ring 3 seem more eye-catching, distinguishes easily.
Described body 1 is provided with over cap 5
Operation principle:
Obsolete the time, because be negative pressure of vacuum in the body 1, be filled with air in the hollow thin-wall rubber ring 3, under the gas pressure of air, hollow thin-wall rubber ring 3 is outwards open, can play sealing function to sealing-plug 2, in the time of air admission body 1, the hollow thin-wall rubber ring 3 that is subjected to gas pressure inwardly shrinks, volume reduces gradually, this time, body 1 interior negative pressure of vacuum more and more was not suitable for blood drawing, when the volume of hollow thin-wall rubber ring 3 is reduced to above the scale mark scope on the lower limit scale mark 4, represented that this blood taking tube is done for.
