Description

Technical Field

[0001] This utility model relates to the technical field of umbilical vein catheterization, and more specifically, to a structure for fixing umbilical vein catheters. Background Technology

[0002] Umbilical vein catheterization is a common medical procedure used to administer intravenous fluids, blood, and medications to premature infants and newborns. It involves inserting a catheter into the newborn's umbilical vein to deliver nutrients and medications. Umbilical vein catheterization is typically performed at the neonatal bedside using sterilized catheters and appropriate techniques.

[0003] In existing technology, the catheter is directly fixed to the umbilical vein of the newborn. There are some fixators on the market for fixing the catheter to the umbilical cord, but these fixators are all split-type, which is relatively troublesome and complicated to operate. In addition, these fixators are generally large, which will bring many inconveniences to the clinical use of umbilical vein fixation. Utility Model Content

[0004] The purpose of this invention is to provide a structure for fixing umbilical vein catheters, aiming to solve the problems of the existing technology where the catheter fixing structure is too large or the operation process is cumbersome.

[0005] This invention is implemented as follows: a fixed umbilical vein catheter structure includes an umbilical vein cannula, one end of which is provided with a connector, and the other end of which is provided with a cannula segment for insertion into the umbilical vein. A skin-friendly fixing cover is provided on the outer periphery of the cannula segment, and the fixing cover has an umbilical positioning opening. The top of the fixing cover is connected to the cannula segment through a fixing structure, the bottom of the fixing cover is provided with a hydrocolloid dressing layer, and the outer periphery of the fixing cover is provided with medical skin-friendly tape. The outer periphery of the cannula segment is provided with a scale for indicating the insertion depth.

[0006] Furthermore, the fixing cover is in the shape of a hollow circle.

[0007] Furthermore, the fixation cover has an umbilical vein opening, one end of the insertion tube segment passes through the umbilical vein opening, and the inner wall of the fixation cover abuts against the outer periphery of the insertion tube segment.

[0008] Furthermore, the umbilical vein opening is circumferentially protruding upward to form a bundle sleeve, which is fitted on the outer periphery of the insertion segment and connected to the fixing structure.

[0009] Furthermore, the fixing structure includes a tube clamp strip, one end of which forms a fixing section that connects to the bundled tube sleeve. The fixing section is fixedly connected to the bundled tube sleeve. The other end of the tube clamp strip forms a fastening head that is detachably connected to the fixing section. When the fastening head is fastened to the fixing section, the tube clamp strip surrounds and closes to form a clamping cavity for clamping the insertion tube section.

[0010] Furthermore, the fastening head is provided with multiple fastening slots spaced apart side by side, and the fastening head and the fixing section are fastened together through the fastening slots.

[0011] Furthermore, the inner wall of the tube clamp strip is provided with multiple anti-slip stripes, which are located in the clamping cavity.

[0012] Furthermore, a fixed lead wire head and a movable lead wire head are provided on the outer side of the bundle sleeve. The fixed lead wire head and the movable lead wire head are arranged opposite to each other. A binding wire is connected to the fixed lead wire head. One end of the binding wire is connected to the fixed lead wire head, and the other end of the binding wire is wound through the insertion tube section and then connected to the movable lead wire head.

[0013] Furthermore, a winding groove is formed in the groove on the outer periphery of the bundle sleeve, and the winding groove is arranged around the outer periphery of the bundle sleeve.

[0014] Furthermore, multiple arc-shaped grooves are formed on both sides of the insertion tube segment, and the multiple arc-shaped grooves are arranged sequentially at intervals along the length direction of the insertion tube segment.

[0015] Compared with existing technologies ， The present invention provides a fixed umbilical vein catheter structure. When the umbilical vein catheter is inserted into the umbilical vein of a newborn, a fixing cover is used to surround the umbilical cord. The fixing cover is then fixed around the umbilical cord with medical skin-friendly tape, thus preventing the catheter segment from directly contacting the skin during drainage, increasing safety. The fixing structure further positions and connects the catheter segment inserted through the fixing cover, preventing the catheter segment from falling off. This structure is simple in design, compact, easy to operate, and suitable for widespread use. It solves the problem of excessively large catheter fixing structures or cumbersome operation processes. The fixing cover contains a skin-friendly, breathable, and sterile hydrocolloid dressing layer, which, through contact with the newborn's skin, increases medical safety. Attached Figure Description

[0024] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0025] The fixed umbilical vein catheter structure includes an umbilical vein cannula 10, with a connector 30 at one end and a cannula segment 20 for inserting into the umbilical vein at the other end. A skin-friendly fixation cover 40 is provided on the outer periphery of the cannula segment 20, and an umbilical positioning opening 41 is provided on the fixation cover 40. The top of the fixation cover 40 is connected to the cannula segment 20 through a fixation structure 50. A hydrocolloid dressing layer 42 is provided at the bottom of the fixation cover 40, and a medical skin-friendly adhesive tape 43 is provided on the outer periphery of the fixation cover 40. A scale for indicating the insertion depth is provided on the outer periphery of the cannula segment 20.

[0026] The aforementioned fixed umbilical vein catheter structure allows the umbilical vein catheter 10 to be inserted into the neonatal umbilical vein via the catheter segment 20. A fixing cover 40 surrounds the umbilical cord 60, and medical skin-friendly tape 43 is used to fix the fixing cover 40 around the umbilical cord 60. This ensures that the catheter segment 20 does not directly contact the skin during drainage, increasing safety. A fixing structure 50 is then used to position and connect the catheter segment 20 inserted within the fixing cover 40, preventing it from falling off. This structure is simple in design, compact, and easy to operate, making it suitable for widespread use. It solves the problems of excessively large fixing structures 50 or cumbersome operation processes. The fixing cover 40 contains a skin-friendly, breathable, and sterile hydrocolloid dressing layer 42, which contacts the neonatal skin, increasing medical safety.

[0027] The fixation cover 40 allows medical staff to observe or access the newborn's umbilical artery through the umbilical positioning opening 41. The length of the cannula segment 20 inserted into the newborn's umbilical vein can be directly observed through the scale, increasing the safety of medical use.

[0028] The size of the fixation cover 40 can be determined according to market demand and patient needs.

[0029] Umbilical vein catheterization 10 is a medical catheter.

[0030] The fixed cover 40 has a trumpet-shaped structure.

[0031] The hydrocolloid dressing layer 42 is a hydrocolloid dressing, which is a dressing made by mixing and processing elastic polymeric hydrogel with synthetic rubber and adhesives. The most common gel in the dressing is carboxymethyl cellulose, which can adhere firmly to the skin at the edge of the wound and can swell up to 12 times after absorbing exudate. The skin-friendly, breathable and sterile hydrocolloid dressing can ensure the medical safety of the skin at the site of the umbilical vein duct in newborns.

[0032] Medical-grade skin-friendly tape 43 can be made from: medical pressure-sensitive tape, paper-based hypoallergenic medical tape, fully transparent and breathable medical tape, waterproof and hypoallergenic medical tape, paper-based hypoallergenic medical tape, etc.; the specific type can be determined according to market demand.

[0033] In this embodiment, the fixing cover 40 is a hollow circular shape. In this way, the inner sidewall of the fixing cover 40 can be filled with the hydrocolloid dressing layer 42.

[0034] In this embodiment, the fixation cover 40 has an umbilical vein opening, one end of the insertion cannula 20 passes through the umbilical vein opening, and the inner sidewall of the fixation cover 40 abuts against the outer periphery of the insertion cannula 20. In this way, the fixation cover 40 can be detached from or slid with the insertion cannula 20.

[0035] In this embodiment, a tubular sleeve 44 extends circumferentially upward from the opening of the umbilical vein. The tubular sleeve 44 is fitted onto the outer periphery of the insertion segment 20 and is connected to the fixing structure 50. In this way, the fixing cover 40 can move the insertion segment 20 in a directional manner through the tubular sleeve 44, and can prevent the insertion segment 20 from bending and becoming blocked.

[0036] In this embodiment, the fixing structure 50 includes a tube clamp 51. One end of the tube clamp 51 has a fixing section 52 that connects to the bundled tube sleeve 44. The fixing section 52 is fixedly connected to the bundled tube sleeve 44. The other end of the tube clamp 51 has a fastening head 53 that is detachably connected to the fixing section 52. When the fastening head 53 is engaged with the fixing section 52, the tube clamp 51 surrounds and closes to form a clamping cavity 54 for holding the insertion tube segment 20. In this way, the tube clamp 51 can be connected to the bundled tube sleeve 44 through the fixing section 52, and the tube clamp 51 can surround and clamp the insertion tube segment 20 through the fastening head 53 and the fixing section 52, thereby positioning and connecting the insertion tube segment 20, preventing the insertion tube segment 20 from falling off, and increasing medical safety.

[0037] In this embodiment, the fastening head 53 is provided with a plurality of fastening grooves 55 spaced apart in parallel, and the fastening head 53 and the fixing section 52 are fastened together through the fastening grooves 55. In this way, the clamping force of the fixing section 52 on the insertion tube section 20 can be adjusted by the position of its connection with the plurality of fastening grooves 55 on the fastening head 53, thereby realizing the clamping adjustment of insertion tube sections 20 of different sizes.

[0038] In this embodiment, the inner wall of the tube clamp 51 is provided with multiple anti-slip stripes 56, which are located in the clamping cavity 54. When the tube clamp 51 surrounds and clamps the insertion tube section 20, the insertion tube section 20 is located in the clamping cavity 54. The clamping cavity 54 increases the frictional resistance between itself and the insertion tube section 20 through the multiple anti-slip stripes 56, preventing the insertion tube section 20 from moving arbitrarily.

[0039] In this embodiment, a fixed wire head 441 and a movable wire head 442 are provided on the outer side of the bundle sleeve 44. The fixed wire head 441 and the movable wire head 442 are arranged opposite to each other. A binding wire 443 is connected to the fixed wire head 441. One end of the binding wire 443 is connected to the fixed wire head 441, and the other end of the binding wire 443 is wound through the insertion tube section 20 and then connected to the movable wire head 442.

[0040] The insertion tube section 20 can be bound by the binding wire 443 on the fixed wire head 441. After binding, the binding wire 443 is then connected and fixed to the movable wire head 442, thereby increasing the positioning connection of the insertion tube section 20 and preventing the insertion tube section 20 from detaching from the fixed cover 40 at will.

[0041] In this embodiment, a winding groove 444 is recessed in the groove on the outer periphery of the bundle sleeve 44, and the winding groove 444 is arranged circumferentially around the outer periphery of the bundle sleeve 44. After the binding wire 443 binds the insertion tube segment 20, the binding wire 443 is wound around the winding groove 444 and then connected and fixed to the movable wire head 442, thereby increasing the positioning connection of the insertion tube segment 20 and preventing the insertion tube segment 20 from detaching at will.

[0042] In this embodiment, multiple arc-shaped grooves 21 are formed on both sides of the intubation segment 20, and these grooves 21 are arranged at intervals along the length of the intubation segment 20. This allows the intubation segment 20 to be wound and positioned by the binding thread 443 through the arc-shaped grooves 21, increasing the connection between the binding thread 443 and the intubation segment 20. The arc-shaped grooves 21 are exposed outside the newborn's umbilical vein and are not located within it, thus not affecting the newborn.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
