Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and nursing technology, specifically to a patch for providing a base for fixing arterial puncture needles. Background Technology
[0002] Arterial puncture and catheterization is a common clinical procedure, with the radial artery and dorsalis pedis artery being the most frequently used vessels. After catheterization, connecting sensors allows for continuous monitoring of indicators such as blood pressure, cardiac output, and stroke variability. Blood samples can also be drawn at any time for relevant tests. This is of great significance for critically ill patients or those who may experience severe fluctuations in their circulatory system during the procedure. The catheter may need to remain in place until the patient's condition stabilizes post-operatively, making proper fixation crucial.
[0003] The existing method based on arterial puncture needle fixation involves placing gauze under the needle handle and at the three-way stop. However, this method may cause pressure marks or even pressure injuries on the skin and carries the risk of infection.
[0004] In view of the above, this application proposes a patch for providing a base for fixing arterial puncture needles to solve the problems of pressure marks and infection. The patch replaces the existing gauze with a more comfortable silicone material to reduce the discomfort of pressure marks, and the patch reduces the contact between the puncture site and the outside world by adhesive fixation. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a patch for providing a base for fixing arterial puncture needles, thus solving the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A dressing for providing a base for fixing an arterial puncture needle, suitable for use between a medical tee and human skin, wherein the medical tee is connected to the arterial puncture needle, comprising,
[0008] Silicone area; placed under the arterial puncture needle, its width is adapted to connect the medical tee to the arterial puncture needle connection point;
[0009] The mucosal layer; it is concave in shape and is attached to the outer wall of the silicone area;
[0010] Coverage area; located on the adhesive side of the mucosa.
[0011] Optionally, the silicone area includes a silicone pad and an antibacterial layer; the antibacterial layer is disposed on the silicone pad.
[0012] Optionally, the mucosal layer may be made of a transparent material.
[0013] Optionally, one side of the mucosal layer is adhesive and can adhere to human skin; the other side is smooth.
[0014] Optionally, the covering area is the same size as the mucosal layer, and the thickness of the connection between the two is equal to that of the silicone area.
[0015] Optionally, the coverage area comprises two end faces and a rear end face;
[0016] Both end faces are of the same size and symmetrically set on both sides of the rear end face.
[0017] Optionally, a protruding point is provided at one edge of both end faces and one rear end face.
[0018] This invention provides a dressing for providing a base for fixing arterial puncture needles, comprising the following features:
[0019] Beneficial effects:
[0020] 1. The silicone area effectively reduces pressure on the skin of the three medical devices and reduces pain at the puncture site during subsequent tearing.
[0021] 2. By coordinating the silicone area with the mucosal layer, the silicone area can be fixed to the maximum extent, reducing the contact between the puncture site and the outside world, and further reducing the chance of infection.
[0022] 3. Through the coordinated design between the mucosal layer and the covering area, since both are the same size and do not obstruct the silicone area, the positional change of the silicone area can be reduced during the removal process. Attached Figure Description

[0029] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] In the description of this utility model, it should be understood that the terms "transverse", "longitudinal", "end face", "edge", "side wall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end face", "head", "tail" and other indications of orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the technical solution of this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0031] To reduce the problems caused by pressure marks on the skin by existing gauze, this application proposes a dressing for providing a base for fixing arterial puncture needles, as detailed below:
[0032] For reference Figure 1 This application mainly consists of a silicone area 3, a mucosal layer 4 located around the silicone area 3, and a covering area 5 located on the mucosal layer 4. This application is placed between the medical tee 1 and the human skin 2, so that the mucosal layer 4 can be bonded to the human skin 2 by removing the covering area 5. At this time, the silicone area 3 is placed under the arterial puncture needle 7, which can reduce the pressure on the skin and the problem of infection.
[0033] For reference Figure 1-2 The silicone area 3 is composed of a silicone pad 31 and an antibacterial layer 32. By using the silicone pad 31 to make its softness and width suitable for the connection position between the medical three-way valve 1 and the arterial puncture needle 7, the pressure of the medical three-way valve 1 on the skin can be effectively reduced; and the antibacterial layer 32 on the silicone pad 31 can effectively avoid the risk of infection.
[0034] It should be noted that the antibacterial layer 32 on the silicone pad 31 can be added to the silicone pad 31 by means of surface coating, impregnation or other methods; and the antibacterial layer 32 is preferably chlorhexidine to achieve the antibacterial properties of the silicone pad 31.
[0035] Since silicone does not have an adhesive effect, it can avoid tearing the area near the puncture point and causing pain when removing it after use.
[0036] For reference Figure 3To address the issue of fixing the silicone area 3, a mucosal layer 4 was further added. The mucosal layer 4 is concave and wraps around the silicone area 3. Its shape effectively controls the movement of the silicone area 3 by covering a large area, minimizing contact between the puncture site and the outside world, and effectively reducing the chance of infection.
[0037] Among them, one side of the mucosal layer 4 is adhesive and can adhere to human skin 2; the other side is smooth; the adhesive side is adhered to the covering area 5; and the mucosal layer 4 is made of transparent material to maximize the distinction between it and the covering area 5, which makes it easier to achieve the front and back sides when placing the silicone area 3.
[0038] For reference Figure 4 To facilitate the use of the covering area 5, since both the covering area 5 and the mucosa layer 4 are concave, the covering area 5 is divided into two side end faces 51 and one rear end face 52 for separate operation. The two side end faces 51 are symmetrically located on both sides of the rear end face 52 and connected to both sides of the silicone area 3. After the silicone area 3 is positioned, the silicone area 3 can be fixed in position by first peeling off the two side end faces 51, and then the rear end face 52 can be peeled off to reinforce the silicone area 3. This can reduce the occurrence of uneven bonding and misalignment during bonding.
[0039] To further explain, the total thickness of the mucosa layer 4 and the covering area 5 is the same as the thickness of the silicone area 3, which increases the smoothness when setting the silicone area 3. Secondly, the covering area 5 is thinner, so the probability of it affecting the thickness of the mucosa layer and the silicone area 3 after being removed is lower.
[0040] For reference Figure 4 In addition, to further improve the ease of tearing off the two side end faces 51 and the rear end face 52, a protruding point 6 is provided on one side edge for convenience.
[0041] For reference Figure 5 Combining the above operations, a film can be provided to fix the arterial puncture needle 7. Later, the fixation conditions are completed by covering the medical three-way valve 1 and the arterial puncture needle 7 with medical-customized tape.
[0042] In this invention, the working steps of the device are as follows:
[0043] 1. First, place the silicone area 3 below the puncture needle handle and position it at the connection point between the medical three-way valve 1 and the arterial puncture needle 7.
[0044] 2. Next, after determining the position of the silicone area 3, peel off the two side end faces 51 in the covering area 5 in sequence;
[0045] 3. Then, expose the mucosal layer 4 and let it adhere to the human skin 2. After that, tear off the rear end face 52 again and connect the mucosal layer 4 in this area to the human skin again, thereby completing the fixation of the silicone area 3.
[0046] 4. Finally, external medical-grade custom tape is used to cover and secure the medical three-way valve 1 and the arterial puncture needle 7.
[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
