Problems solved by technology

[0003] The deep venous catheter is often drawn from the carotid artery, and the deep venous catheter at the carotid artery must be firmly pasted as an external catheter. Once the deep venous catheter falls off, the patient will need to reinsert the deep venous catheter, which will increase the The pain of the patient is also not conducive to the recovery of the patient's body. The existing method of fixing the deep vein catheter in the neck is to stick it directly with an adhesive tape, which is not reliable enough

Embodiment 1

[0038] Such as Figure 1 to Figure 6 As shown, a secondary fixing device for the end of a deep vein catheter includes a medical adhesive tape 1, wherein the medical adhesive tape 1 has a first sticking surface 11 and a first rough surface 12, and the medical adhesive tape 1 has better air permeability and can To avoid adverse effects such as peeling of the patient's skin, the first sticking surface 11 of the medical tape 1 sticks to the neck of the patient, and the first sticking surface 11 can be used to stick the medical tape 1 to the patient's body; in order to fix the deep vein The catheter is more secure, and two first straps 2 are pasted on the first rough surface 12 of the medical adhesive tape 1, wherein on the same face of the first straps 2 there are a first hook face 21 and a second sticking face 22, the second The first hook surface 21 of a strap 2 is bonded to the first rough surface 12 of the medical adhesive tape 1, so that the first strap 2 can be fixed on the ...

Embodiment 2

[0055] The difference from Example 1 is the preparation of the antifouling coating on the surface of the hoop, wherein the preparation method of the antifouling coating is as follows:

[0056] Take the following components by weight for subsequent use: 17 parts of epoxy resin, 25 parts of polytetrafluoroethylene, 9 parts of polyvinyl chloride, 8 parts of polypropylene, 48 parts of acetone, 5 parts of disodium edetate, carbonic acid 5 parts of vinylene ester, 5 parts of fluoroethylene carbonate;

[0057] S1. Preparation of the first prefabricated solution: Add epoxy resin, polytetrafluoroethylene, polyvinyl chloride and polypropylene to acetone for dissolution, stir evenly, heat the overall temperature to 72°C, and heat-preserve for 1 hour to obtain the first prefabricated solution liquid;

[0058] S2. Prepare the second prefabricated solution: mix vinylene carbonate and fluoroethylene carbonate uniformly, heat to 62° C., and heat-preserve for 0.5 h to obtain the second prefab...

Embodiment 3

[0063] The difference from Example 1 is the preparation of the antifouling coating on the surface of the hoop, wherein the preparation method of the antifouling coating is as follows:

[0064] Take the following components by weight for subsequent use: 13 parts of epoxy resin, 22 parts of polytetrafluoroethylene, 10 parts of polyvinyl chloride, 8 parts of polypropylene, 48 parts of acetone, 5 parts of disodium edetate, carbonic acid 5 parts of vinylene ester, 5 parts of fluoroethylene carbonate;

[0065] S1. Preparation of the first prefabricated solution: Add epoxy resin, polytetrafluoroethylene, polyvinyl chloride and polypropylene to acetone for dissolution, stir evenly, heat the overall temperature to 72°C, and heat-preserve for 1 hour to obtain the first prefabricated solution liquid;

[0066] S2. Prepare the second prefabricated solution: mix vinylene carbonate and fluoroethylene carbonate uniformly, heat to 62° C., and heat-preserve for 0.5 h to obtain the second prefa...

Abstract

The invention discloses a deep vein indwelled tube tail end twice-fixing device. The technical scheme is characterized in that the device comprises a medical adhesive tape with a first adhesive face and a first rough face, the first adhesive face of the medical adhesive tape is adhered to the neck of a patient, two first binding tapes are adhered to the first rough face of the medical adhesive tape and provided with first hook faces and second adhesive faces, the first hook faces of the first binding tapes are adhered to the first rough face of the medical adhesive tape, and the second adhesive faces of the first binding tapes are adhered to the neck of the patient. First fixing pieces are fixed to the medical adhesive tape, each first fixing piece is provided with two circular grooves, elastic convex blocks are inserted into the grooves and fixed to second fixing pieces, and hoops are fixed to the second fixing pieces and the first binding tapes. By the deep vein indwelled tube tail end twice-fixing device, a deep vein indwelled tube can be firmly fixed.

Description

technical field [0001] The invention relates to the field of catheter fixing devices, more specifically, it relates to a secondary fixing device for the end of deep vein catheterization. Background technique [0002] Deep venous catheterization is also called central venous catheterization. Central venous catheterization is an important channel for continuous CVP detection, fluid replacement, blood transfusion, parenteral nutrition, and input of various rescue drugs such as vasoactive drugs during and after surgery in critically ill patients. In addition, it also avoids repeated puncture of peripheral veins, and has been repeatedly promoted, especially in intensive care units such as ICU and CCU. [0003] The deep venous catheter is often drawn from the carotid artery, and the deep venous catheter at the carotid artery must be firmly pasted as an external catheter. Once the deep venous catheter falls off, the patient will need to reinsert the deep venous catheter, which will...
