Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: an anti-slipping central venous catheter comprises an internal catheter 1, wherein one end of the internal catheter 1 is sleeved with a first connecting piece 3, the first connecting piece 3 is in threaded connection with a second connecting piece 4, the second connecting piece 4 is of a Y-shaped structure, and the other two ends of the second connecting piece 4 are respectively embedded with an extension tube 5, the two extension tubes 5 can be detached from the whole catheter through the first connecting piece 3 and the second connecting piece 4, when the extension tubes 5 are damaged, the extension tubes can be replaced in time, the problem that the whole catheter is detached to cause untimely rescue is solved, meanwhile, the patient can be prevented from being punctured again, so that when the extension tubes 5 are damaged, the patient can be protected as far as possible, the other ends of the two extension tubes 5 are sleeved with third connecting pieces 6, and are connected with an external syringe or other medical equipment through the third connecting pieces 6, so as to realize central venous pressure measurement, large-scale and quick venous transfusion and the like, the built-in catheter 1 and the extension tube 5 are both sleeved with a clamp 7, the clamp 7 sleeved on the built-in catheter 1 can cut off the connection between the built-in catheter 1 and the extension tube 5 when the extension tube 5 is damaged, so that blood can be prevented from flowing into the extension tube 5 through the built-in catheter 1 and flowing out through the damaged extension tube 5 or being infected at the damaged extension tube 5 to cause danger, the clamp 7 sleeved on the extension tube 5 can close the other extension tube 5 when measuring central venous pressure, a large amount of rapid venous transfusion and the like, interference caused by the other extension tube 5 is reduced, so that nursing can be normally carried out, a convex block 2 is arranged on the outer surface of the built-in catheter 1, a slide hole 8 is arranged on the upper surface of the convex block 2, a wire slot 11 is arranged at the position where the convex block 2 is parallel to the built-in catheter 1, a semicircular cavity 10 is arranged at the joint of the slide hole 8 and the wire slot 11, and a spring plate 9, and shell fragment 9 and lug 2 pass through the fastener block and are connected, through the shell fragment 9 that is equipped with, appear becoming flexible or other reasons lead to the ductus venosus to have the slippage phenomenon to appear in fixed sticky tape of usefulness, the patient can be stabbed to shell fragment 9, feel through the acupuncture and remind the patient to inspect the sticky tape or don't move about on a large scale, avoid the ductus venosus to drop, there is string 12 shell fragment 9 in the centre of a circle department that is located semi-circular cavity 10 through the leg joint, and string 12 extends to outside lug 2 through wire casing 11.

Further, the needle 13 is embedded in the first connecting piece 3 at the other side of the internal catheter 1, the needle 13 extends out of the first connecting piece 3, the needle 13 pierces the medical rubber sheet 14 and penetrates into the second connecting piece 4, the internal catheter 1 can be communicated with the external catheter 5, blood can flow into the external catheter 5 from the internal catheter 1, and meanwhile, medicine can flow into the internal catheter 1 from the external catheter 5.

Furthermore, the medical rubber sheet 14 is embedded at the joint of the second connecting piece 4 and the first connecting piece 3, so that the insecure connection between the first connecting piece 3 and the second connecting piece 4 is prevented, blood or medicine flows out from a gap, and meanwhile, bacteria can be prevented from flowing into the central venous catheter from the first connecting piece 3 and the second connecting piece 4.

Further, the length of the built-in catheter 1 is more than fifteen centimeters, and the other end of the built-in catheter 1, which is positioned at the first connecting piece 3, is provided with a puncture needle, so that the built-in catheter can be conveniently punctured into the vein of the patient.

Furthermore, the bump 2 is of a flat structure, two ends of the bump are both smoothly connected with the built-in catheter 1, so that a doctor can conveniently puncture the bump 2 into the body of a patient, and the distance between the bump 2 and the puncture needle of the built-in catheter 1 is thirteen centimeters to fifteen centimeters.

Further, the terminal acute angle isosceles triangle structure that is of shell fragment 9, conveniently appears the big action and leads to central ductus venosus to appear stimulating the patient when not hard up in the patient, and further not hard up appears in central ductus venosus, and the length of shell fragment 9 is less than the arc limit length of semi-circular cavity 10 to the length of shell fragment 9 is greater than the degree of depth of slide opening 8.

The working principle is as follows: when the central venous catheter is used, firstly, the clamp 7 on the built-in catheter 1 is closed, then the built-in catheter 1 is punctured into the vein of a patient through the puncture needle on the built-in catheter 1, when the central venous catheter is pushed to the lug 2, the string 12 is pulled towards the direction of the first connecting piece 3, the elastic piece 9 deforms and contracts into the semicircular cavity 10, the venous catheter is continuously pushed until the proper depth is punctured, the string 12 is released, the elastic piece 9 is recovered and punctured into the body of the patient, then the needle 13 is punctured into the medical rubber piece 14, the second connecting piece 4 is rotated, the second connecting piece 4 is in threaded connection with the first connecting piece 3, the part of the built-in catheter 1 outside the skin is fixed through the adhesive tape, secondly, after the fixation, when the built-in catheter 1 moves outwards due to the turning over or other activities of the patient, the elastic piece 9 can puncture the body of the patient, the next step of action of the patient is prevented from continuously causing the built-in catheter 1, in addition, when the extension tubes 5 are damaged, the second connecting piece 4 can be rotated, the two extension tubes 5 are detached from the whole catheter and replaced by installing the extension tubes 5, and finally, when the patient does not need to use the central venous catheter, the thin rope 12 can be pulled outwards to deform the elastic sheet 9 and contract the elastic sheet into the semicircular cavity 10, and the whole built-in catheter 1 can be pulled out.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
