Deep vein catheterization fixing patch

Abstract

This utility model relates to a deep vein catheter fixation patch, comprising a fixation patch body that can adhere to the skin at the puncture site. An opening for the catheter to pass through is provided on the fixation patch body. A puncture site disinfection pad surrounds the edge of the opening and contacts the skin at the puncture site. The first tip of the catheter passes through the opening and is fixed to the outer surface of the fixation patch body. A heat-sealing film covers the outer wall of the catheter. A second tip of the catheter is fixed to the outer surface of the fixation patch body. The puncture site disinfection pad surrounds the edge of the opening and directly contacts the skin at the puncture site. This continuously disinfects and sterilizes the skin around the puncture site, effectively inhibiting microbial growth. It can fill any gaps that may exist between the catheter and the skin, blocking the pathway for microorganisms to enter the body. The heat-sealing film covering the outer wall of the catheter forms a physical barrier, reducing contact between external microorganisms and the catheter, and preventing microorganisms from spreading along the outer wall of the catheter to the puncture site.

Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a deep vein catheter fixation patch. Background Technology

[0002] Deep vein catheterization mainly includes three common methods: internal jugular vein catheterization, subclavian vein catheterization, and femoral vein catheterization. Taking subclavian vein catheterization as an example, after placement, adhesive tape is currently used to fix the deep vein catheter to the skin on the lateral side of the clavicle. However, in actual clinical nursing, patients often need to undergo intravenous infusions and other procedures through the catheter during treatment. During infusions, the infusion tubing is pulled and displaced by the operation of the infusion pump. Nurses also apply force to the infusion tubing when changing infusion bags or adjusting the infusion rate. These external forces are all transmitted to the catheter. At the same time, patients' daily activities, such as turning over in sleep, extending their arms to touch objects, getting up to sit, or getting out of bed, can all cause displacement of the shoulder, neck, and lateral clavicle area, thus applying external forces of varying directions and magnitudes to the catheter. Under the combined effect of multiple external forces, deep vein catheters frequently shift. Once the catheter shifts, gaps will appear between the originally tightly fitted catheter and the skin. Hospitals are complex environments teeming with microorganisms. These microorganisms are present in the air, on the surfaces of medical devices, and on medical staff and patients themselves. These microorganisms can easily enter the body through the gap between the catheter and the skin, colonize the skin surface, and multiply rapidly, causing local skin inflammation, manifesting as redness, swelling, pain, and itching. If the infection is not controlled promptly and effectively, the microorganisms will spread along the puncture site to deeper tissues, causing more serious infections at the puncture site. This not only increases patient suffering and prolongs hospital stays but may also lead to serious complications such as bacteremia and sepsis, endangering the patient's life, significantly increasing medical costs, and markedly enhancing the difficulty and complexity of nursing care. Utility Model Content

[0003] In view of the shortcomings of the prior art, a deep vein catheter fixation patch is provided, which can effectively fix the deep vein catheter and avoid infection at the puncture point or other skin sites caused by gaps between the deep vein catheter and the skin during actual use.

[0004] To achieve the above and other related objectives, this utility model proposes a deep vein catheter fixation patch, comprising:

[0005] The fixation patch can adhere to the patient's outer skin near the puncture point;

[0006] An opening for the insertion tube to pass through is provided on the fixing body;

[0007] A puncture site disinfection pad is placed around the edge of the opening and in contact with the skin at the puncture site.

[0008] The first tube head of the tube passes through the opening and is fixed to the outer surface of the fixing body;

[0009] A heat-sealing film is used to cover the outer wall of the insertion tube.

[0010] The second tube head of the tube is fixed to the outer surface of the fixing body.

[0011] In one embodiment of this utility model, the fixing patch body is provided with an opening, the opening is strip-shaped and penetrates through the opening.

[0012] In one embodiment of this utility model, extended flanges are provided on both sides of the opening, and the extended flanges are fixed together by adhesive.

[0013] In one embodiment of this utility model, the outer surface of the fixing patch is provided with an adhesive fixing area, and the second tube head of the placement tube is fixed on the adhesive fixing area.

[0014] In one embodiment of this utility model, a fixing adhesive is provided on the outer surface of the fixing patch, and the fixing adhesive is used to fix the placement tube.

[0015] In one embodiment of this utility model, the fixing sticker body is flattened to present an overall waist shape, and a crease is provided at the position of the fixing sticker body. The fixing sticker body is folded in half by the crease, and the two ends of the fixing sticker body are pasted together by the adhesive fixing area.

[0016] In one embodiment of this utility model, the inner side of the fixation patch body where the puncture point disinfection pad is provided has a tear-off film, and the tear-off film matches the outer contour of the fixation patch body.

[0017] In one embodiment of this utility model, the edge of the sealing film is provided with a tear angle.

[0018] In one embodiment of the present invention, a first adhesive area and a second adhesive area are respectively provided on the inner side of the fixing patch body near both ends, and the first adhesive area is arranged around the puncture point disinfection pad.

[0019] By adopting the above technical solution, the technical effect of this utility model is as follows: This deep vein catheter fixation patch is firmly adhered to the patient's lateral skin near the clavicle. With the opening design, the catheter can be accurately inserted and firmly restrained. The first and second catheter heads are fixed on the outer surface of the fixation patch body, which further strengthens the fixation effect on the catheter and ensures that the catheter can still be maintained in a relatively stable position under various complex external forces, thus ensuring the continuity and safety of treatment.

[0020] The puncture site disinfection pad is placed around the edge of the opening and comes into direct contact with the skin at the puncture site. It can continuously disinfect and sterilize the skin around the puncture site, effectively inhibiting the growth of microorganisms. Its close fit to the skin at the puncture site can fill any gaps that may occur between the catheter and the skin, blocking the way for microorganisms to enter the body. The heat-sealing film covers the outer wall of the catheter, forming a physical barrier, reducing the contact between external microorganisms and the catheter, and preventing microorganisms from spreading along the outer wall of the catheter to the puncture site. The synergistic effect of multiple protective measures greatly reduces the risk of infection at the skin and puncture site, alleviates patient pain, shortens the hospitalization period, and reduces medical costs.

[0021] The fixation patch is designed to conform to the contours of the skin on the outer side of the clavicle, making it easy to apply and providing high patient comfort. The opening and fixation tip design allow medical staff to quickly and accurately locate and connect the catheter during procedures such as infusions, eliminating the need for repeated searching and adjustments, thus saving time. Furthermore, the stable fixation reduces the need for repeated adjustments and re-fixation due to catheter displacement, significantly improving nursing efficiency and providing patients with higher-quality and more efficient nursing care.

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] The frequency of manual turning is difficult to control precisely. If turning is delayed, patients remain in the same position for extended periods, greatly increasing the risk of complications such as pressure sores. Statistics show that the incidence of pressure sores in ICUs due to delayed turning is as high as 20%-30%. Pressure sores not only increase patient suffering and prolong hospital stays but also raise treatment costs and infection risks. Furthermore, the inconsistency and standardization of movements during manual turning can cause unnecessary pulling and vibration, potentially affecting wound healing, especially for postoperative, fractured, or severely traumatized patients. While some assisted turning devices exist on the market, most are single-function and cannot meet the complex and diverse nursing needs of ICU patients. Some devices only perform simple side-turning movements, lacking precise adjustment of turning angles and intervals, making it difficult to adapt to the personalized nursing requirements of patients with different conditions. Therefore, it is urgent to develop an efficient, precise, and adaptable intermittent turning device that can adapt to the complex nursing environment of the ICU. To address this, a deep vein catheterization fixation patch is proposed, comprising: a fixation patch body 10, which can adhere to the patient's skin near the puncture site; an opening 11 for the catheter to pass through on the fixation patch body 10; a puncture site disinfection pad 20, which surrounds the edge of the opening 11 and contacts the skin at the puncture site; a first tube head 31 of the catheter 30 passing through the opening 11 and fixed to the outer surface of the fixation patch body 10; a heat-sealing film 40 covering the outer wall of the catheter 30; and a second tube head 32 of the catheter 30 fixed to the outer surface of the fixation patch body 10.

[0034] In one embodiment, the fixation patch body 10 can be a high-density medical non-woven fabric, and adhesive is provided on the inner side of the fixation patch body 10 so that the fixation patch body 10 can be attached to the outer skin position near the clavicle.

[0035] In one embodiment, the first tube head 31 of the insertion tube 30 passes through the opening 11 and extends out of the outer side of the fixing adhesive body 10. It is surrounded by the puncture point disinfection pad 20 and can tightly wrap the insertion tube 30, eliminating the gap between the insertion tube 30 and the skin, thereby avoiding infection at the puncture point.

[0036] In one embodiment, the heat-sealing film 40 covers the outer wall of the insertion tube 30, which can form a physical barrier to isolate the insertion tube 30, reduce the contact between external microorganisms and the insertion tube, and prevent microorganisms from spreading along the outer wall of the insertion tube to the puncture point. The synergistic effect of multiple protective measures greatly reduces the risk of infection on the skin and at the puncture point.

[0037] In one embodiment, after the heat-sealing film 40 is wrapped around the insertion tube 30, the insertion tube 30 can be effectively wrapped by a hot air blower.

[0038] In one embodiment, the puncture site disinfection pad 20 can be coated with a bactericidal gel, which can effectively kill germs around the puncture site.

[0039] In one embodiment, to facilitate the insertion of the first tube head 31 of the insertion tube 30 into the opening 11, the fixing body 10 is provided with an opening 12, which is strip-shaped and penetrates the opening 11.

[0040] In one embodiment, see Figure 2 and Figure 3 The view has two states: one is to wrap the tube 30 and make the tube 30 extend outward; the other is to provide extended flanges 121 on both sides of the opening 12, and the extended flanges 121 are fixed together by adhesive.

[0041] In one embodiment, adhesive tape is provided on the extended flanges 121 on both sides of the opening 12. When the first tube head 31 of the insertion tube 30 is located inside the opening 11, the extended flanges 121 are wrapped by the adhesive tape, so that a seal is formed between the insertion tube 30 and the skin, thereby eliminating the gap between the insertion tube 30 and the skin.

[0042] In one embodiment, in order to fix the second tube head 32 of the placement tube 30 and prevent the second tube head 32 from shifting arbitrarily, an adhesive fixing area 13 is provided on the outer side of the fixing body 10, and the second tube head 32 of the placement tube 30 is fixed on the adhesive fixing area 13.

[0043] In one embodiment, a fixing adhesive 15 is provided on the outer side of the fixing body 10, and the fixing adhesive 15 is used to fix the placement tube 30.

[0044] In one embodiment, before being unfolded, the fixing sticker body 10 is flattened and presents an overall waist shape. A crease 14 is provided at the position of the fixing sticker body 10. The fixing sticker body 10 is folded in half by the crease 14, and the two ends of the fixing sticker body 10 are glued together by the adhesive fixing area 13.

[0045] In one embodiment, the two ends of the fixing body 10 are glued together by the adhesive fixing area 13 through the fold 14, which makes it convenient to unfold and stick in actual use.

[0046] In one embodiment, to protect the fixation patch body 10, a tear-off film 50 is provided on the inner side of the puncture point disinfection pad 20 of the fixation patch body 10, and the tear-off film 50 matches the outer contour of the fixation patch body 10.

[0047] To facilitate tearing open the sealing film 50, the edge of the sealing film 50 is provided with a tearing angle 51, which protrudes from the edge of the fixing body 10.

[0048] In one embodiment, a first adhesive area 16 and a second adhesive area 17 are respectively provided on the inner side of the fixing patch body 10 near both ends, and the first adhesive area 16 is arranged around the puncture point disinfection pad 20.
