Description
Technical Field
The utility model relates to a medical equipment technical field especially relates to an automatic ration vein blood sampling pipe of disposable.
Background
At present, the main methods used in venous blood sampling in China are two types: the first method is to use a disposable syringe to draw blood, and has the disadvantages that the blood volume needs to be artificially controlled, the blood is drawn too much or too little by taking little attention, and sometimes the blood overflows from a test tube during the process of injecting the blood into the test tube to pollute the environment, thereby causing cross infection in hospitals. The second method is to use a vacuum blood collection tube, and clinical application of the blood collection device discovers that external air enters a negative pressure tube under the action of atmospheric pressure when a puncture needle is punctured into the negative pressure tube in use, so that the blood collection is stopped due to insufficient pressure difference, the blood collection amount at one time is insufficient, the negative pressure tube needs to be replaced, in the process of replacing the negative pressure tube, the puncture needle needs to be pulled out and quickly inserted into the new negative pressure tube, and blood on the puncture needle head is very easy to drop in the process.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, a disposable automatic quantitative intravenous blood collection tube is provided, which aims to achieve the effect of blood collection by manual operation without replacing the negative pressure tube when the blood collection amount is insufficient due to insufficient pressure in the negative pressure tube.
The specific technical scheme is as follows:
the utility model provides an automatic ration intravenous blood collection tube of disposable, is including storing up blood vessel, outer tube and sealing ring, the sealing ring is fixed set up in store up blood vessel mouth of pipe periphery, store up blood vessel's mouth of pipe end by the one end port of outer tube stretches into in the outer tube, the sealing ring periphery with the laminating of outer tube inner wall, and the two sliding connection, the other end port of outer tube is provided with and supplies pjncture needle male sealing plug, store up blood vessel with airtight space is constituteed jointly to the outer tube, just airtight space sets up to the negative pressure state.
Foretell automatic ration intravenous blood collection tube of disposable still has such characteristic, the fixed spacing ring that is provided with of one end port inside wall of outer tube, the inside wall of spacing ring with store up the laminating of vascular lateral wall, and the two sliding connection, in order to prevent the outer tube with store up the blood vessel separation.
The beneficial effect of above-mentioned scheme: when the blood sampling pressure in the closed space is not enough, the outer sleeve is pushed to enable the outer sleeve and the blood storage tube to move relatively, the volume of the closed space is increased, blood of a patient is continuously extracted, when the sealing ring moves to be in contact with the limiting ring, the volume of the closed space is increased to the limit, and the outer sleeve and the blood storage tube can be prevented from being completely separated.
The disposable automatic quantitative intravenous blood collection tube is characterized in that a convex ring which can be pushed and pulled by medical staff is arranged on the outer side wall of the port at one end of the outer sleeve.
The beneficial effect of above-mentioned scheme: when the medical staff finds that the blood sampling pressure in the closed space is reduced and the blood sampling amount is too small, the lower part of the blood storage vessel is held by a single hand, and the fingers push the bulge rings to continue blood sampling.
The disposable automatic quantitative intravenous blood collection tube is characterized in that scales are arranged on the outer side wall of the blood storage tube along the length direction of the blood storage tube.
The beneficial effect of above-mentioned scheme: the medical staff can judge the volume of the blood which has been pumped conveniently.
In conclusion, the scheme has the beneficial effects that:
the utility model provides an among the disposable automatic ration vein blood sampling tube, constitute the negative pressure space jointly through outer tube and blood storage tube, when blood sampling pressure is not enough in the negative pressure space, can manually promote the outer tube and make pressure increase continue to draw blood in the negative pressure space. The utility model provides an automatic ration intravenous blood sampling pipe of disposable has when pressure is not enough in the negative pressure space and lead to the volume of taking a blood sample not enough, does not change the effect that the negative pressure pipe can continue the blood sampling through manual operation.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be further described with reference to the following specific examples, which should not be construed as limiting the invention.
FIG. 1 is a schematic diagram of a front-cut structure of a disposable automatic quantitative intravenous blood collection tube of the present invention before use, FIG. 2 is a schematic diagram of a front-cut structure of a disposable automatic quantitative intravenous blood collection tube of the present invention after use, FIG. 3 is a schematic diagram of a separation structure of a blood storage tube and an outer tube of a disposable automatic quantitative intravenous blood collection tube of the present invention, as shown in FIGS. 1, 2 and 3, the disposable automatic quantitative intravenous blood collection tube provided by the present embodiment comprises a blood storage tube 1, an outer tube 2 and a sealing ring 3, the sealing ring 3 is fixedly disposed at the periphery of the orifice of the blood storage tube 1, the orifice end of the blood storage tube 1 extends into the outer tube 2 from one end port of the outer tube 2, the periphery of the sealing ring 3 is attached to the inner wall of the outer tube 2, and the two are slidably connected, a sealing plug 4 for inserting a puncture needle is disposed at the other end port of the outer tube 2, the blood storage tube 1 and the outer tube 2 jointly form a sealed space, and the closed space is set to be in a negative pressure state.
