[0002] The indwelling needle fixation patch is used by medical staff to fix the indwelling needle when doing intravenous infusion. After puncture, the existing indwelling needle fixation method is to fix it with a medical dressing. Due to sweating in summer or when the body moves, the indwelling needle is easy to loosen, which can easily cause the needle to roll and cause secondary damage to the wound. Moreover, after the indwelling needle is fixed, the three-way and protective cap of the indwelling needle are usually in direct contact with the arm or the back of the hand, which can easily cause pressure damage to the indwelling needle and cause new wounds on the skin directly contacted by the indwelling needle.

[0024] Please refer to Figures 1-6 As shown in the figure, this embodiment provides a fixing patch for preventing indwelling needle pressure sores. The indwelling needle fixation is for medical staff to fix the indwelling needle during intravenous infusion. After puncture, the existing indwelling needle fixing patch is only a medical dressing for fixing the indwelling needle. Due to easy sweating in summer or when the human body moves, the indwelling needle is very easy to loosen, which easily leads to needle rolling and causes secondary injury to the wound. After the indwelling needle is fixed, usually the three-way joint and the protective cap of the indwelling needle are in direct contact with the arm or the back of the hand, causing pressure injury to the indwelling needle and generating a new wound surface on the skin in direct contact with the indwelling needle. Therefore, we propose a fixing patch for preventing indwelling needle pressure sores as follows: It includes a transparent dressing 1. Transparent release films 13 are adhered to the upper and lower layers of the transparent dressing 1. The middle layer of the transparent dressing 1 is a medical polyurethane film 12. When the medical polyurethane film 12 is not in use, transparent release films 13 are adhered to both the upper and lower surfaces to prevent the adhesive layer from being contaminated with dust. A medical pressure-sensitive adhesive 11 is coated on the lower end surface of the medical polyurethane film 12. When the medical polyurethane film 12 is in use, the side coated with the medical pressure-sensitive adhesive 11 is covered on the upper surfaces of the fixing mechanism 2 and the indwelling needle 3 and adhered to the skin. The fixing mechanism 2 includes at least a first non-woven fabric adhesive patch 21 and a second non-woven fabric adhesive patch 22. One end of the first non-woven fabric adhesive patch 21 is fixedly connected to one end of the second non-woven fabric adhesive patch 22. A sponge block 24 is fixedly connected to the middle of the lower surface of the first non-woven fabric adhesive patch 21. Water-based emulsion adhesives are coated on the side surfaces of the first non-woven fabric adhesive patch 21 and the second non-woven fabric adhesive patch 22 close to the sponge block 24. When the fixing mechanism 2 is not in use, a film 23 covers the water-based emulsion adhesive surfaces of the first non-woven fabric adhesive patch 21 and the second non-woven fabric adhesive patch 22 to prevent the adhesive layer from being contaminated with dust.

[0025] The indwelling needle 3 is located between the first non-woven fabric adhesive patch 21 and the second non-woven fabric adhesive patch 22, and the protective cap 31 of the indwelling needle 3 is directly above the sponge block 24. An infusion three-way joint 32 is fixedly connected to the outer surface of the protective cap 31. One end of the infusion three-way joint 32 is fixedly connected to a PVC infusion tube 34, and one end of the protective cap 31 is fixedly connected to an indwelling needle tip 33.

[0026] The utility model is specifically used after puncture: the indwelling needle 3 is placed between the first non-woven adhesive tape 21 and the second non-woven adhesive tape 22 in the fixing mechanism 2, and the film 23 on the first non-woven adhesive tape 21 is torn off first, the first non-woven adhesive tape 21 is located below the protective cap 31, and the end of the first non-woven adhesive tape 21 away from the second non-woven adhesive tape 22 is covered on the infusion tee 32 and the PVC infusion tube, the first non-woven adhesive tape 21 is adhered to the skin and the infusion tee 32 and the PVC infusion tube, and after the infusion tee 32 is fixed, the protective cap 31 will not rotate. At this time, the protective cap 31 of the indwelling needle 3 is located directly above the sponge block 24, and the sponge block 24 plays a role of pressure buffering to avoid causing pressure damage to the skin and protect the skin, and then the film 23 on the second non-woven adhesive tape 22 is torn off and covered on the upper surface of the protective cap 31 and the first non-woven adhesive tape 21, so as to fix the indwelling needle and prevent it from swinging left and right.

[0027] After fixing the indwelling needle 3, the upper and lower transparent release films 13 of the transparent dressing 1 are torn off, and the middle layer of medical polyurethane film 12 coated with medical pressure-sensitive adhesive 11 is covered on one side on the fixing mechanism 2 and the upper surface of the indwelling needle 3 and adhered to the skin, thereby reinforcing the fixing effect of the indwelling needle 3. The medical polyurethane film 12 is waterproof, breathable, and thin, and is suitable for medical use. The upper and lower layers of the transparent dressing 1 are adhered with a transparent release film 13 to prevent the adhesive layer from being contaminated with dust and to create a sterile environment, so that a sterile environment can be created at the wound while fixing the indwelling needle.

[0028] In order to facilitate the access to the medical polyurethane film 12 on the middle layer of the transparent dressing 1, a pull tab 14 is fixedly connected to the transparent release film 13. When in use, the pull tab 14 on the transparent release film 13 coated with the medical pressure-sensitive adhesive 11 is pulled by hand, and the transparent release film 13 is torn off and covered on the upper surface of the fixing mechanism 2 and the indwelling needle 3 and adhered to the skin, and then the upper transparent release film 13 is torn off, so that the medical polyurethane film 12 can be quickly taken out after puncture.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
