Detailed Description
Examples
The indwelling needle for a patient with thrombocytopenia provided by the present embodiment, as shown in fig. 1, comprises a needle head a, a catheter b connected with the needle head a, and an application structure for fixing the needle head a and the end of the catheter b, wherein the application structure comprises an application main body 1, a first patch part 2 arranged on the application main body 1, and a second patch part 3 arranged on the first patch part 2 for fixing the needle head a and rapidly stopping bleeding in case of accidental detachment of the needle head a.
In this embodiment, the lower surface of the applicator body 1 is a conventional medical adhesive layer for fixing the whole device on the hand of the patient, the first patch 2 is located on the lower surface of the applicator body 1, has a shape corresponding to the shape of the applicator body 1, but has a smaller size than the applicator body 1, and may not have tackiness in this embodiment, and is fixed to the hand of the patient by the applicator body 1, and the second patch 3 is provided in the middle of the first patch 2 corresponding to the puncture site for fixing the needle a.
As shown in fig. 1 and 2, the first patch part 2 includes a patch body 201, and two thickened adhesive strips 202 disposed on two sides of the patch body 201. The thickness of thickening bonding bar 202 is followed the direction of syringe needle a promptly the side direction grow of rubberizing body 201, and thicker one end is close to pipe b tip, just the maximum thickness of thickening bonding bar 202 is not more than the thickness of pipe b.
In the application process of the traditional application, as the indwelling needle has a plurality of structures, the catheter b connected with the needle head a is mainly used for influencing the effect of fixing the indwelling needle, after the puncture of the needle head a is completed, the needle head a and the catheter b are often fixed together by the traditional application, and as the catheter b has a certain thickness, the needle head a is fixed in an inclined state, and a gap is formed between the application and the needle head a, so that the needle head a is easy to fall off and the application is easy to fall off when the hand of a patient moves.
In order to solve the above problems, two thickened adhesive strips 202 with inverted right trapezoid cross sections are arranged on two sides of the patch body 201, the maximum thickness of each thickened adhesive strip 202 is not greater than the thickness of the conduit b, when the needle head a and the conduit b fall off, the two thickened adhesive strips 202 can be adhered to the hand of the patient, so that the gap between the application structure and the hand caused by the falling off of the conduit b is reduced, the whole application body fits the hand of the patient more, and the application structure is prevented from falling off.
As shown in fig. 3, the second patch 3 includes a groove 301 provided on the patch body 201, a hemostatic block 302 provided in the groove 301, and a fixing member 303 provided on the groove 301 and fixing the hemostatic block 302. The fixing member 303 includes a fixing strip 303a, two first bonding blocks 303b disposed at two ends of the fixing strip 303a and bonded to the patch body 201, and a second bonding block 303c disposed on the fixing strip 303a and bonded to the needle a.
In this embodiment, recess 301 sets up on the cloth pasting body 201, just recess 301 is close to the tip one side of pipe b is opened up, is used for the insertion of syringe needle a, hemostatic mass 302 is the better hemostatic material of compression and resilience effect, generally adopt commonly used hemostatic sponge can, hemostatic mass 302 is hemostatic sponge and is not exceeded when the compression is complete recess 301, and thickness when opening completely is greater than the degree of depth of recess 301 and be less than the thickness of thickening bonding strip 202 avoids right syringe needle a with pipe b's fixed production influence. The fixing strip 303a is used for compressing and fixing the hemostatic block 302, the two first bonding blocks 303b are arranged on the upper surfaces of two sides of the fixing strip 303a and used for fixing the fixing strip 303a, the second bonding block 303c is arranged on the lower surface of the middle of the fixing strip 303a and used for bonding with the needle head a, and the bonding strength of the second bonding block 303c and the needle head a is greater than the bonding strength of the two first bonding blocks 303b and the patch body 201.
As shown in fig. 2 and 4, the working principle of the present embodiment is as follows: after the puncture is finished, aligning the second bonding block 303c with the needle head a, adjusting the direction of the thickened bonding strip 202 to be horizontally aligned with the direction of the needle head a as much as possible, then fixing the whole application structure on the hand, and slightly pressing the second bonding block 303c to ensure that the second bonding block 303c is fully bonded with the needle head a, thereby finishing the fixation; when the needle head a falls off, the needle head a has better bonding effect with the first bonding block 303b, the needle head a drives the whole fixing strip 303a to fall off from the application structure together, the viscosity of the two thickening bonding strips 202 for supplementing the application structure ensures that the whole application structure is still fixed on the hand of the patient, and the blood stopping block 302 which is not limited by the fixing strip 303a rebounds to press on the puncture site for stopping bleeding.
