Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a dressing for deep vein catheterization to prevent skin wounds from being exposed and infected. Background Art

[0002] Deep vein catheterization is a widely used catheterization method in clinical practice. It can be placed in multiple locations, such as the subclavian vein, internal jugular vein, femoral vein, etc. The specific nursing requirements for catheterization in different locations are also different. Internal jugular and subclavian catheterization are relatively hygienic and not easily contaminated. Regular local disinfection and replacement of external dressings are required. The catheter should be sealed in time after use. Heparin saline can be used for sealing. Even when not in use, regular sealing and dressing replacement care is required. It should be noted here that in temporary catheterization of hemodialysis, especially after internal jugular vein catheterization, the neck has a large range of motion, and the catheter is facing upward, the catheter has a large free range of motion, and gaps are easily formed between the dressing and the catheter, resulting in the skin of the catheterization site being exposed to a contaminated environment, resulting in an increased risk of infection; when placing a femoral vein catheter in the groin, it is also necessary to pay attention to good fixation and protection, because the catheter is close to the genitals, to avoid contamination by urine, feces and other dirt. In the actual clinical medical process, the patient moves after deep venous catheterization, resulting in the dressing layer. The skin layer and the dressing layer are often not tightly connected, and gaps are often left, which is not conducive to the patient's care, prone to infection, affecting recovery, and increasing hospitalization time.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Embodiment 1:

[0021] The hospital adopts a dressing for deep vein catheterization of the utility model for deep vein fistula patients. Figure 1-Figure 3 As shown, a dressing for deep vein catheterization includes a tape 1 and a dressing layer 2, wherein the adhesive layer of the tape 1 is arranged downward, the area of ​​the dressing layer 2 is smaller than that of the tape 1, and the dressing layer 2 is a 5*7.5 cm rectangle as a whole, and is horizontally arranged below the middle of the lower end of the tape 1, the rear side of the upper end of the dressing layer 2 is bonded to the adhesive layer of the tape 1, and the front side of the upper end is not bonded to the adhesive layer of the tape 1, and an interlayer can be used to avoid sticking to the adhesion layer, and a through hole 4 for the deep vein catheter 3 to penetrate is provided at the upper end of the front side, and the through hole 4 is basically arranged along the central axis of the dressing, with a diameter of about 0.4 cm, and the through hole 4 is inclined, and its lower end is inclined toward the right end of the dressing layer 2.

[0022] In this embodiment, in the traditional dressing fixing catheter, after the dressing is loosened, the patient is prone to have a gap in the wound surface, the gap exposes the skin wound, and is directly contaminated by the deep vein catheter 3, which enters the blood and causes bacteremia or even sepsis, posing a great safety hazard; in order to avoid a gap between the dressing and the skin, in this embodiment, as Figure 1-Figure 2 As shown, the tape 1 plays a fixing role, the dressing layer 2 is horizontally arranged below the middle of the lower end of the tape 1, and the upper rear side of the dressing layer 2 is bonded to the adhesive layer of the tape 1, so that the front part of the tape 1 can be lifted relative to the dressing layer 2. The dressing can be made of a dressing with anti-inflammatory effect. When used specifically, the lower end of the dressing layer 2 is fitted with the wound, the upper front side of the tape 1 is lifted, and the tube head of the deep vein catheter 3 is inserted into the human blood vessel through the perforation 4 on the dressing layer 2, and then the upper front side of the tape 1 is adhered to the skin and connected to the deep vein catheter 3 at the same time to fix the wound. The deep vein catheter 3 is fixed to the human skin; the dressing layer 2 can effectively avoid the formation of a gap between the tape 1 and the human skin. At the same time, the dressing layer 2 has a certain anti-inflammatory effect. While protecting the wound, it can also have a certain anti-inflammatory effect. The dressing layer can also be arranged into six groups of unconnected strips, each strip is approximately a 0.6*7.2cm rectangle, and the spacing between the strips is 0.1cm. While ensuring the dressing effect, it also has both air permeability and strength, ensuring that the overall dressing is not easily displaced relative to the patient, thereby improving the use effect of the dressing.

[0023] Embodiment 2:

[0024] In another embodiment of the present invention, an ST-6 patch is used. Figure 4-Figure 5 As shown, it also includes a connecting portion 5, which is arranged between the adhesive layer of the tape 1 and the front side of the upper end of the application layer 2 and is connected to the two respectively, and the connecting portion 5 is provided with a through hole 6 arranged in a horizontal direction and connected to the perforation 4; the connecting portion 5 is made of sponge material. In this embodiment, the sponge material is a medical sponge sheet with a thickness of 0.1 cm and a size of approximately a 1.1*2.0 rectangular.

[0025] In this embodiment, in order to enhance the stability of the connection between the deep vein catheter 3 and the human skin after insertion, an elastic connecting portion 5 is provided between the adhesive layer of the tape 1 and the front side of the upper end of the dressing layer 2. The connecting portion 5 is provided with a through hole 6 connected to the perforation 4, and the through hole 6 connected to the perforation 4 is provided for the tube head of the deep vein catheter 3 to pass through. The deep vein catheter 3 is fixed by the connecting portion 5, and when the deep vein catheter 3 is shaken by external force, it is cushioned to a certain extent.

[0026] One end of the connecting portion 5 is thermally fixedly connected to the dressing layer 2, and the other end is suspended and arranged in the style of a connecting button, so as to facilitate fastening and connection to delicate parts such as the patient's arms and ankles.

[0027] It should be noted that, in order to ensure reliable connection, the connection portion 5 should be arranged at a position substantially tangent to the through hole 6, so that the tube head of the venous catheter 3 can contact the connection portion 5 through the through hole 6, but it does not affect the reinforcement strength of the contact portion 5. Adhesive tapes may also be provided in the middle of the front and rear ends of the connection portion 5. By providing adhesive tapes in the middle of the front and rear ends of the connection portion 5, the connection portion 5 and the human skin are connected through the adhesive tapes, so that the connection portion 5 and the human skin are tightly connected, and the stability of the deep venous catheter 3 is further ensured.
