[0010] The following further describes the present utility model with reference to the accompanying drawings: As can be seen from the attached Figure 1 drawings, a new type of venous indwelling needle for preventing skin damage and its supporting dressing of the present utility model mainly includes a steel needle 1, a catheter 2, a catheter hub 3, a transparent three-way with sponge pad 6, an isolation plug 4, a needle holder 5, a safety device 7, a flexible tube 10, a dot mark 14, a Y-shaped interface 11, a heparin cap 12, a positive pressure connector 13, a sliding groove 8 and a pulley 9. The steel needle 1, the needle holder 5 and the safety device 7 are an integrated overall structure for preventing needle stick injuries, which can be rotated left and right and pulled backward. The catheter 2 is directly connected to the catheter hub 3. One end of the transparent three-way with sponge pad 6 is connected to the catheter hub 3, and the other end is connected to the flexible tube 10. The isolation plug 4 is arranged inside the transparent three-way with sponge pad 6, and the sponge pad of the transparent three-way with sponge pad 6 is arranged below the transparent three-way. A dot mark 14 with a diameter of 0.2 cm is provided at a position 3 cm from one end of the flexible tube 10 close to the transparent three-way with sponge pad 6. The other end of the flexible tube 10 is a Y-shaped interface 11, which are respectively a positive pressure connector 13 and a heparin cap 12.

[0011] When the novel anti - skin - injury intravenous indwelling needle and the supporting dressing of the utility model are used for puncture operation, the steel needle 1 is placed in the middle of the catheter 2. The nurse holds the needle handle 5 and inserts the catheter 2 containing the steel needle 1 into the vein. After seeing blood return, the steel needle 1 is withdrawn until the whole of the steel needle 1, the needle handle 5 and the safety device 7 are removed. The sponge pad of the transparent three - way connector 6 with a sponge pad is arranged under the transparent three - way connector. The thickness of the sponge pad is about 0.2 mm. The length of the catheter seat 3 end of the transparent three - way connector 6 with a sponge pad is 1.5 cm, and the length of the extension tube end of the transparent three - way connector 6 with a sponge pad is 1 cm. When placing the indwelling needle, the sponge pad under the transparent three - way connector 6 with a sponge pad is only 0.2 mm thick, which does not interfere with the indwelling operation. Moreover, the sponge pad uses polyurethane material, which has low sensitization and can reduce skin adverse reactions. At the same time, the sponge pad has air permeability, and the patient will feel comfortable during use.

[0012] For the novel anti - skin - injury intravenous indwelling needle and the supporting dressing of the utility model, a sliding groove 8 is provided on the flexible tube 10. The sliding groove 8 is inclined, with the narrower part close to the puncture point and the wider part close to the infusion end. A pulley 9 is arranged in the sliding groove 8, and the bottom of the pulley 9 fits the outer wall of the flexible tube 10. During use, the pulley 9 is adjusted to rotate in the sliding groove 8 to open the flexible tube 10 for normal infusion and to adjust the infusion speed. After the infusion is completed, the pulley 9 is adjusted to rotate in the sliding groove 8 to close the flexible tube 10 to prevent venous blood reflux. Through clinical trials, the pressure generated during the rolling of the pulley 9 can return the refluxed blood to the blood vessel, preventing blood clots from blocking the needle or forming thrombus, which may cause adverse events. At the same time, it is optimal that 1 - 3 cm of the sliding groove 8 is close to the end of the transparent three - way connector 6 with a sponge pad when it is closed. At 3 cm from the end of the flexible tube 10 close to the transparent three - way connector 6 with a sponge pad, a dot mark 14 with a diameter of 0.2 cm is made, which can play a role in reminding that the optimal closing position is at 1 - 3 cm (including 3 cm).

[0013] According to the attachment Figure 2 As an improvement, the novel anti - skin - injury intravenous indwelling needle and the supporting dressing of the utility model further include a transparent dressing 15 and a self - adhesive elastic band 16. The middle of the transparent dressing 15 is a transparent film. The transparent three - way connector 6 with a sponge pad and the catheter seat 3 are covered under the transparent dressing 15. The self - adhesive elastic band 16 covers the periphery of the transparent dressing 15. The two ends of the transparent dressing 15 use the self - adhesive elastic band 16, and the self - adhesive elastic band 16 gradually becomes narrower outward. The self - adhesive elastic band 16 is made of elastic fibers, fiber glue coated with latex micro - particles, and has air permeability, elasticity and skin - friendliness.

[0014] The utility model relates to a novel indwelling needle for preventing skin damage and a matching dressing. The length and width of the transparent dressing 15 are 6x7 cm, and the surrounding is covered with a self-adhesive elastic band 16. The uncovered part in the middle has a length and width of 5x5 cm. The four corners of the inner side of the transparent dressing 15 are arc-shaped, and the four corners of the outer side are inclined downward. The width of the self-adhesive elastic band 16 covered up and down is 0.5 cm, and the width of the self-adhesive elastic band 16 covered left and right is 3 cm. It extends from both sides of the transparent dressing 15 respectively, and the total extension length of both sides is 52 cm and the width is 3 cm. Among them, the length of one side is 14 cm, and the length of the other side is 38 cm. At the 32 - 38 cm position at the end of the longer side, it is divided into two extension bands each with a width of 1.5 cm.

[0015] When in use, the combination of the transparent dressing 15 and the self-adhesive elastic band 16 makes the patient feel more comfortable. Especially for the extended self-adhesive elastic band 16 with a combination of long and short lengths, when fixing, first fix the short end of the self-adhesive elastic band 16, and then fix the long end of the self-adhesive elastic band 16. The tail part of the long end is separated, and the "Y" - type pasting method is adopted during use, which can avoid the indwelling needle part, reduce skin pressure, and at the same time, the pasting is firm. Moreover, the self-adhesive elastic band 16 can be trimmed at will during use, which is applicable to all patients receiving intravenous infusion, especially suitable for scalp vein puncture of infants and young children.
