Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the disposable self-locking blood vessel marking belt with a developing function comprises a blood vessel blocking belt 1, wherein the blood vessel blocking belt 1 is a latex tube made of latex or a rectangular belt made of latex, the blood vessel blocking belt 1 is divided into a fixed section 11 and a penetrating section 12 along the length direction, the fixed section 11 is provided with a notch 2 for the penetrating section 12 to penetrate, and the surface of the penetrating section 12 is provided with a baffle column 3; wherein, penetrate section 12 under the exogenic action and drive the fender post 3 and pass opening 2 to make fixed section 11 and penetrate between the section 12 and form a clamp ring to the blood vessel centre gripping, and under the barrier action of fender post 3 in order to avoid penetrating section 12 and return to initial position from opening 2.

Compared with the conventional vascular occlusion belt, the vascular occlusion belt can complete the latching of the blood vessel without clamping by a clamp, and the automatic clamping and locking can be realized only through the structure of the vascular occlusion belt.

When the blood vessel blocking belt is used, the end part of the fixed section 11 penetrates the notch 2, a clamping ring for blocking blood flow of a blood vessel is formed on the elastic belt, meanwhile, the notch 2 is of an oval or straight-line structure, the outer diameter of the notch 2 is smaller than the outer contour size of the blood vessel blocking belt 1, the penetrating section 12 penetrating into the notch 2 is in a contracted state, namely the cross section of the penetrating section 12 penetrating into the notch 2 is smaller, the primary locking of the penetrating position of the penetrating section 12 is realized under the elastic resilience force of the penetrating section 12 in the penetrating notch 2 for recovering the natural state cross section size, and the penetrating section 12 is prevented from retreating to the initial position from the notch 2 under the blocking effect of the baffle column 3, so that the complete locking of the blood vessel blocking belt 1 is realized.

Specifically, as shown in fig. 1-3, the blocking posts 3 are provided with a plurality of blocking posts 3, and the plurality of blocking posts 3 are sequentially arranged on the penetrating section 12 at equal intervals, so that the penetrating section 12 and the notch 2 can be locked at different positions, and the size of the clamping ring is adjusted.

When the clamping ring needs to be adjusted according to the thickness of the blood vessel of the patient, the fixing section 11 or the penetrating section 12 is pulled, so that the number of the baffle posts 3 penetrating through the opening 2 is increased, namely, the more the number of the baffle posts 3 penetrating through the opening 2 is increased, the smaller the size of the clamping ring between the fixing section 11 and the penetrating section 12 is.

After passing through the opening 2, the baffle column 3 cannot be retracted from the opening 2 under the action of external force, so that the clamping force on the blood vessel is reduced to cause large-area bleeding, and the setting direction of the baffle column 3 is required to be limited.

Specifically, the baffle column is obliquely arranged on the penetrating segment 12, and the opening end of the included angle between the baffle column and the penetrating segment 12 faces to one side, close to the opening 2, of the baffle column so that the baffle column can be clamped at the opening 2, therefore, after the baffle column 3 passes through the opening 2, the baffle column can be opened to be abutted against the fixed segment 11, and at the moment, the distance between the farthest part of the baffle column 3 and the penetrating segment 12 is larger than the distance between the penetrating segment 12 and the farthest part of the opening, namely, the baffle column 3 locks the penetrating segment 12 in the opening 2 completely.

Further, the opening 2 is of an oval or straight-line structure, the outer diameter of the opening 2 is smaller than the outer outline size of the vascular occlusion belt 1, so that after the penetrating section 12 penetrates into the opening 2, the opening 2 can automatically clamp the penetrating section 12 under the action of self elastic deformation, preliminary clamping and fixing are achieved, and secondary locking of the baffle column 3 is facilitated.

Because the opening 2 external diameter is less, when penetrating section 12 and passing, penetrate section 12 too big external diameter and be inconvenient for opening of opening 2, when using, need consider opening 2 to penetrate section 12 and pass, more waste time and energy like this, be unfavorable for the operation to go on, in order to avoid the production of this kind of phenomenon.

Specifically, the front end of the penetrating segment 12 is a conical prism 5 protruding outwards, so that the penetrating segment 12 passes through the notch 2.

Further, the inner cavity of the vascular occlusion belt 1 is of a hollow structure, the inner cavity of the vascular occlusion belt 1 is in a closed state with the notch 2, and the hollow part of the vascular occlusion belt 1 is filled with the developing marker 4, so that the position of the vascular occlusion belt 1 can be accurately mastered.

The developing marking agent 4 is a contrast agent used in medicine, so that the medical staff can observe conveniently, and when the blocking belt is sheared off and falls, the medical staff can find out and take out the blocking belt from human tissues conveniently and rapidly through own marks, and the medical staff is prevented from searching difficultly in a surgical field.

The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
