Description

Technical Field

[0001] The utility model relates to the technical field of fixing exposed deep vein catheters, in particular to a fixing device for exposed deep vein catheters. Background Art

[0002] The general puncture site of deep venous catheter is in the subclavian vein, femoral vein or internal jugular vein, but the exposed end of the catheter in clinical practice is usually not fixed and is therefore susceptible to traction, detachment, contamination, etc.

[0003] In order to solve the above problems, Chinese invention patent CN113975592A discloses a novel postoperative fixation device for deep venous catheter for nursing. The protective film is first peeled off, and then the fixing plate is attached to the patient's skin surface through the adhesive layer. Then the cover is opened, and then the catheter is placed along the serpentine groove, and then the cover is covered to fix the installation position of the catheter.

[0004] However, since the deep vein catheter structure is not a regular shape, it includes a catheter seat and an infusion connector, which can only restrict the tube part and still cannot better fix the deep vein catheter structure; the fixation effect still needs to be further improved by using an adhesive layer to stick it on the patient's skin surface.

[0005] Based on this, the utility model designs a deep vein exposed catheter fixing device to solve the above problem. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a deep vein exposed catheter fixing device.

The bottom of the clamping component 1 is bonded with the adhesive component 2 for attaching to the skin surface.

[0035] The locking assembly 1 includes a box body 11 with an opening at the top, an elastomer, and an irregular groove provided inside the elastomer for locking the deep vein exposed sliding tube assembly 4 therein. The elastomer is placed inside the box body 11, and the outer shape of the elastomer matches the inner shape of the box body 11.

[0036] A fixing assembly 3 is provided on the top of the box body 11 , and the middle part of the fixing assembly 3 blocks the opening of the box body 11 , thereby limiting the position of the elastic body inside the box body 11 and the deep vein exposed sliding tube assembly 4 .

[0037] When in use, the top opening of the box 11 is opened through the fixing component 3, the deep vein exposed sliding tube component 4 is stuck in the irregular groove inside the elastomer, and then the fixing component 3 is covered on the top of the box 11, so as to block the top of the box 11. The fixing component 3 can limit the elastomer and the deep vein exposed sliding tube component 4 inside the box 11, and can better fix the deep vein catheter structure; and because the fixing component covers the top opening of the box, the deep vein exposed sliding tube component is wrapped inside to avoid contamination; then the adhesive component 2 is attached to the skin surface, which is conducive to fixing the vein exposed sliding tube component 4 during infusion or no infusion.

[0038] Example 2

[0039] In some embodiments, please refer to the attached instructions. Figure 1-4 , the elastic body adopts a sponge block 12.

[0040] The adhesive assembly 2 includes a protective film 21 and a double-sided adhesive film 22.

A clip 44 is provided in the first clamping groove 14, and one end of the clip 44 can be clamped on the body of the connecting tube 2 46. The included angle between the arc groove 13 and the first clamping groove 14 is 90 degrees, which is conducive to further increasing the movement resistance to prevent the deep vein exposed sliding tube assembly 4 from shifting.

[0045] When no infusion is performed, the connecting tube 1 42 is inserted into the groove 16, the catheter seat 43 is inserted into the second slot 15, the infusion connector 45 is inserted into the connector slot 17, the clip 44 is inserted into the first slot 14, and the connecting tube 2 46 is inserted into the arc groove 13, thereby realizing the clamping and limiting effect on the deep vein exposed sliding tube assembly 4 to avoid the displacement of the deep vein exposed sliding tube assembly 4. The slot is designed according to the shape of the deep vein exposed sliding tube assembly 4, which has a better limiting effect on the deep vein exposed sliding tube assembly 4.

[0046] During infusion, the ends of the first Velcro 31 and the third Velcro 33 are bonded to the second Velcro 32 to fix the deep vein exposed sliding tube assembly 4 on the sponge block 12. When adding medicine, the second Velcro 32 is separated from the first Velcro 31, the infusion connector 45, the connecting tube 2 46 and the clip 44 are taken out, and the infusion connector 45 is connected to the external infusion tube. At the same time, the first Velcro 31 and the third Velcro 33 are bonded to fix the catheter seat 43, thereby ensuring the stability of the deep vein exposed sliding tube assembly 4 during infusion.
