Abstract
The utility model discloses an anti-drop venous cannula, which comprises an inflatable air bag containing air and a fixed air bag without air, wherein the inflatable air bag is connected with the fixed air bag through a connecting pipe, and the air in the inflatable air bag enters the fixed air bag through extrusion; the inflatable air bag and the fixed air bag are internally provided with a vein cannula in a penetrating way, and the connecting pipe is tightly attached to the vein cannula. When the vein cannula is carried out, the inflatable air bag is extruded, air inside the inflatable air bag enters the shriveled fixed air bag which enters the blood vessel, the blood vessel is enabled to generate a bulge, then the operation line is tied at the left end and the right end of the bulge, the falling probability of the vein cannula is greatly reduced, the vein cannula can be left in an animal body for a longer time, and more experiments with higher difficulty and longer time can be completed.
Description
Technical Field
The utility model relates to a vein intubate especially relates to an anti-drop vein intubate.
Background
In animal experiments, intravenous cannula operations, such as self-administration experiments, are often required to be performed on animals. These procedures involve inserting a tube into the leg vein and jugular vein of the animal, and after fixation, administering the drug continuously for a long period of time, or injecting the drug as necessary. When carrying out the vein cannula operation, one of the difficult problem that often can meet is how to prevent the vein cannula and drop, this is because the vascular wall is very smooth and elastic, and after the vein cannula inserted the blood vessel, the blood vessel can produce an outside power, even firmly tie up vascular wall and vein cannula with the operation line, also often can meet the condition that the vein cannula drops, and operation operator usually can take the method of ligature many times to try to fix vein cannula and vascular wall, but only just by taut line or ligature many times, tie up many times and can not solve the problem completely.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art's defect, provide an anti-drop vein intubate, when vein intubate, make blood vessel produce an arch, then tie up the operation line at both ends about bellied, greatly reduced the probability that vein intubate drops, make vein intubate can persist longer time in the animal body to accomplish more, the degree of difficulty is bigger, the longer experiment of time.
In order to solve the technical problem, the utility model provides an anti-drop venous cannula, which comprises an inflatable air bag containing air and a fixed air bag without air, wherein the inflatable air bag and the fixed air bag are connected through a connecting pipe; the inflatable air bag and the fixed air bag are internally provided with a vein cannula in a penetrating way, and the connecting pipe is tightly attached to the vein cannula.
Preferably, the connecting tube between the inflatable airbag and the fixed airbag is provided with a fixing line or a fixing clip for preventing the gas in the fixed airbag from flowing back to the inflatable airbag.
Preferably, the material of the inflatable air bag and the fixed air bag is rubber.
Preferably, the diameter of the fixation balloon is smaller than the diameter of the blood vessel.
Preferably, the inflatable balloon, the fixing balloon, the connecting tube and the venous cannula are integrally formed.
Preferably, the length of the connecting tube is 3 cm, and the length of the venous cannula is 12 cm.
The utility model discloses the beneficial effect who reaches: when the vein cannula is carried out, the inflatable air bag is extruded, air inside the inflatable air bag enters the shriveled fixed air bag which enters the blood vessel, the blood vessel is enabled to generate a bulge, then the operation line is tied at the left end and the right end of the bulge, the falling probability of the vein cannula is greatly reduced, the vein cannula can be left in an animal body for a longer time, and more experiments with higher difficulty and longer time can be completed.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of the anchoring balloon inserted into a blood vessel;
FIG. 3 is a schematic view of the structure of the inflatable balloon being squeezed into the anchoring balloon to bulge the blood vessel.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the utility model provides an anti-drop venous cannula, which comprises an inflatable air bag 1 containing air and a fixed air bag 3 without air, wherein the inflatable air bag 1 and the fixed air bag 3 are connected through a connecting pipe 2, the whole device is in a totally closed state, and the air in the inflatable air bag 1 is extruded into the fixed air bag 3; the inflatable air bag 1 and the fixed air bag 3 are internally penetrated with a vein intubation tube 4, and the connecting tube 2 is tightly attached to the vein intubation tube 4. The inflatable air bag 1, the fixed air bag 3, the connecting pipe 2 and the venous cannula 4 are integrally formed. And a fixing line or a fixing clamp for preventing the gas in the fixed air bag 3 from flowing back to the inflatable air bag 1 is arranged on the connecting pipe 2 between the inflatable air bag 1 and the fixed air bag 3. The material of the inflatable air bag 1 and the fixed air bag 3 is rubber (isoprene rubber), and the inflatable air bag has certain toughness and cannot be broken when being pressed after being inflated like a balloon. The diameter of the fixation balloon 3 is smaller than the diameter of the blood vessel 5. The length of the connecting pipe 2 is 3 cm, and the length of the venous cannula 4 is 12 cm (4 cm for intravascular access and 8 cm for extravascular use).
The position where the fixed air sac 3 is adhered to the venous cannula 4 needs to be calculated, and the best condition is that when the venous cannula 4 reaches the required position in the blood vessel 5, another air sac 1 containing air is just exposed out of the fracture opening of the blood vessel 5 (see figure 2), at the moment, the air sac 1 is squeezed to make the air inside enter the shriveled fixed air sac 3 which enters the blood vessel 5 (see figure 3), then the connecting pipe 2 between the air sac 1 exposed out of the blood vessel 5 and the fixed air sac 3 is fixed by a fixing wire or a fixing clamp, the connecting pipe 2 between the air sac 1 and the fixed air sac 3 is not communicated with the venous cannula 4, after the air sac 1 is inflated into the fixed air sac 3, the gas can not flow back to the air sac 1, namely, the gas in the air sac 5 can not return to the air sac through the pipe.
The utility model discloses a leading parts is for having the vein intubate 4 of aerifing gasbag 1 and fixed gasbag 3, just begin fixed gasbag 3 to be located the shrivelled state and tightly attached on vein intubate 4, make fixed gasbag 3 can get into blood vessel 5 along with vein intubate 4 together, treat vein intubate 4 and get into blood vessel 5 back completely, aerify in 1 to fixed gasbag with aerifing gasbag, make fixed gasbag 3 swell, it is protruding that blood vessel 5 is from inside to outside produces like this, both ends about with the fixed bellied of operation line then, prevent that vein intubate 4 from droing, make vein intubate 4 can persist longer time in the animal body, in order to accomplish more, the degree of difficulty is bigger, the longer experiment of time.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
