Description

Technical Field

[0001] The utility model relates to the field of medical hemostasis, in particular to an aseptic transparent pressurized fixed hemostasis device. Background Art

[0002] The peripherally inserted central catheter (PICC) has the advantages of long catheter retention time, simple maintenance and operation, wide application range, high safety, and high catheter biocompatibility. It can provide patients with an effective and safe venous access and reduce the pain of repeated punctures. However, because it is a vascular invasive operation, the skin tissue needs to be incised during the operation, which can easily lead to complications such as bleeding and exudation, and its incidence rate can reach more than 90%. Bleeding and exudation at the puncture site not only increase the risk of infection and the number of maintenance times, but also increase the economic burden on patients and affect their quality of life. Therefore, it is particularly important to reduce the amount of bleeding and exudation during and after PICC catheterization.

[0003] At present, elastic bandages are often used in clinical practice to compress and stop bleeding. However, the strength is often insufficient and difficult to control. Even if the pressure of the elastic bandage can be increased artificially, the pressure is dispersed and cannot be concentrated and pressed vertically above the puncture site, so the hemostasis effect is poor. If the pressure is too tight, it will cause obstruction of venous return, and continuous venous hypertension will easily cause local tissue necrosis. The white pressurized fixation belt is not conducive to nurses and patients to observe the bleeding at the puncture site in time. Utility Model Content

[0004] In order to overcome the above problems, the utility model provides a sterile transparent pressurized fixed hemostasis device to solve the shortcomings and defects of existing hemostasis methods, enhance the hemostasis effect, facilitate nursing staff to observe the hemostasis status, reduce the patient's pain and the nursing staff's workload, and is conducive to achieving rapid hemostasis.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a sterile transparent pressurized fixed hemostatic device, comprising a fixing plate, a pressurized component is arranged below the fixing plate, the upper surface of the pressurized component is fitted with the inner wall surface of the fixing plate, an adhesive layer is arranged on the upper surface of the pressurized component, an absorption layer is arranged on the lower surface of the pressurized component, the absorption layer is against the position of the patient's wound, a sterile transparent dressing is used to fix the fixing plate on the patient's upper arm, and the tension of the sterile transparent dressing forms a pressure on the lower surface of the pressurized component that acts vertically on the patient's wound.

[0006] Preferably, the fixing plate is made of a transparent rigid material and is in the shape of a thin plate with an arc-shaped structure and rounded edges.

[0007] Preferably, the lower surface of the booster assembly is a circular planar structure or a circular convex structure.

[0008] Preferably, the material of the booster component is a transparent soft silicone material, and the edges are a rounded structure.

[0009] Preferably, the absorption layer is a liquid-permeable absorption patch.

[0010] The middle of the sterile transparent dressing is provided with a transparent part, and the two ends are provided with elastic parts. The sides of the sterile transparent dressing close to the two ends are coated with adhesive.

[0011] Preferably, the fixing plate and the booster assembly are sterilized.

[0012] Compared with the existing solutions, the beneficial effects of the utility model are:

[0013] The utility model discloses a sterile transparent pressurized fixed hemostasis device, in which a pressurized component is arranged under a fixed plate, so that under the normal tension of a sterile transparent dressing, the lower surface of the pressurized component can form a greater vertical pressure on the patient's wound, thereby increasing the compression effect; the fixed plate and the pressurized component are made of transparent materials, which is beneficial for nursing staff and patients to observe the wound; the upper surface of the pressurized component is coated with an adhesive layer, so that displacement between the pressurized component and the fixed plate is not easy to occur, and at the same time, the absorption layer on the lower surface of the pressurized component absorbs liquid exuded from the wound, which is beneficial for hemostasis and healing of the wound.

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 8 As shown, a sterile transparent pressurized fixed hemostatic device is provided in the embodiment of the exemplary embodiment one of the utility model, comprising a fixing plate 1, a pressurized component 2 is arranged below the fixing plate 1, the upper surface of the pressurized component 2 is in contact with the inner wall surface of the fixing plate 1, an adhesive layer 5 is arranged on the upper surface of the pressurized component 2, an absorption layer 3 is arranged on the lower surface of the pressurized component 2, the absorption layer 3 is against the position of the patient's wound, a sterile transparent dressing 4 is used to fix the fixing plate 1 on the upper arm of the patient, and the tension of the sterile transparent dressing 4 forms a pressure on the lower surface of the pressurized component 2 acting vertically on the patient's wound.

[0028] like Figures 1 to 8In the implementation of the exemplary embodiment 1 of the utility model, the arc length of the fixing plate 1 is 50mm, the width is 50mm, and the thickness is 2mm. The fixing plate 1 is made of a transparent material, such as glass, transparent resin, etc. The material has a high hardness and is not easily deformed under the tension of the sterile transparent dressing 4. The edges of the fixing plate 1 are provided with rounded corners to avoid scratching the patient's skin during use. The fixing plate 1 acts on the upper surface of the booster component 2 through the inner wall surface. The upper surface of the booster component 2 is an arc-shaped surface, which is coaxial with the inner wall surface of the fixing plate 1, thus ensuring that the upper surface of the booster component 2 and the inner wall surface of the fixing plate 1 are completely fitted. The contour of the upper surface of the booster component 2 is circular with a radius of 11mm, and the lower surface is a circular plane with a radius of 9mm, which gradually narrows from the upper surface to the lower surface. The absorption layer at the bottom of the booster component 2 abuts against the patient's wound, forming a large local pressure. The material of the booster component 2 is a transparent soft silicone material. The edges of the pressurizing assembly 2 are rounded to prevent scratching of the patient's skin during use. Because the fixing plate 1, the pressurizing assembly 2 and the transparent portion 6 of the transparent dressing 4 are all made of transparent materials, medical staff can conveniently observe the hemostasis of the puncture site.

[0029] like Figure 3 to Figure 7 In the implementation of the first exemplary embodiment of the utility model, the lower surface of the booster component 2 is a circular plane structure so that the absorption layer at the bottom of the booster component 2 can abut the patient's wound well. The upper surface of the booster component 2 is coated with an adhesive layer 5, such as double-sided tape, liquid glue, mucous membrane, etc. After coating the adhesive layer 5, the upper surface of the booster component 2 and the inner wall surface of the fixed plate 1 are tightly bonded together, and it is not easy to slip or shift during use; the lower surface of the booster component 2 is provided with an absorption layer 3 with a thickness of 5mm, which is an exudate absorption patch, which can absorb wound exudate, keep the wound moist, promote wound healing, and provide a good moist healing environment for the wound.

[0030] like Figure 1 , Figure 8 In the embodiment of the first exemplary embodiment of the utility model, the sterile transparent dressing 4 is a film transparent dressing, a transparent portion 6 is arranged in the middle of the sterile transparent dressing 4, and elastic portions 7 are arranged at both ends. The sterile transparent dressing 4 is coated with adhesive near both ends, and the adhesive is coated with polyacrylate adhesive, which has good viscosity and can realize the binding of the fixing plate 1 and the booster assembly 2 on the upper arm of the patient. The transparent portion is made of a transparent film (polyurethane), and the hemostasis of the patient's wound can be observed through the transparent portion.

[0031] like Fig. 9 In the implementation of the second exemplary embodiment of the present invention, the lower surface of the booster assembly 2 is a circular convex structure so that the absorption layer at the bottom of the booster assembly 2 can abut the patient's wound well.

[0032] like Fig.10 In the implementation of the third exemplary embodiment of the present invention, the upper surface of the booster assembly 2 is an arc-shaped surface, which is coaxial with the inner wall surface of the fixing plate 1, thus ensuring that the upper surface of the booster assembly 2 and the inner wall surface of the fixing plate 1 are completely fitted. The contour of the upper surface of the booster assembly 2 is a square with a side length of 11 mm, and the lower surface of the booster assembly 2 is a circular plane with a radius of 9 mm, which gradually narrows from the upper surface to the lower surface. The absorption layer at the bottom of the booster assembly 2 abuts against the patient's wound, forming a large local pressure.

[0033] Working principle: After the patient has a puncture, the exudate absorption patch on the lower surface of the booster component 2 is placed on the patient's wound, and the fixing plate 1 is placed on the upper surface of the booster component 2. The upper surface of the fixing plate 1 is covered with a sterile transparent dressing 4, and the two ends of the sterile transparent dressing 4 are bonded to the patient's skin. The tension of the sterile transparent dressing 4 causes the fixing plate 1 to form an axial pressure. The upper surface of the booster component 2 fits the inner wall surface of the fixing plate 1, and the absorption layer at the bottom of the booster component 2 abuts against the patient's wound, so that the wound is locally squeezed strongly, achieving the purpose of rapid hemostasis.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
