Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a catheter three-way valve fixing assembly. Background Technology

[0002] In clinical departments, some patients with indwelling central venous catheters often require dual-channel intravenous infusion, which is commonly achieved using a three-way valve. A medical three-way valve consists of a screw cap, valve body, and valve core.

[0003] During clinical intravenous infusions, ordinary medical adhesive is typically used to secure the three-way valve. However, because this adhesive adheres to the skin, the area in contact with the valve is prone to pressure, leading to poor patient comfort. Furthermore, the exposed, protruding three-way valve is susceptible to external force, causing the adhesive tape to detach and potentially leading to tubing kinking. This necessitates repeated securing, increasing the likelihood of adhesive allergies in patients. Moreover, medical staff must remove and re-secure the tape when changing infusion sets or three-way valves, a cumbersome and time-consuming process.

[0004] Therefore, it is necessary to improve the existing three-way valve fixing assembly. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a catheter three-way valve fixing component that avoids pressure damage to the patient's skin caused by the three-way valve.

[0006] To achieve the above technical effects, the technical solution of this utility model is as follows: a catheter three-way valve fixing assembly, including a flexible pad, an adhesive layer, a three-way valve body and a limiting assembly, wherein the adhesive layer is fixedly disposed on the adhesive surface of the flexible pad, and the limiting assembly is used to fix the three-way valve body to the bearing surface of the flexible pad, wherein the adhesive surface and the bearing surface are disposed opposite to each other.

[0007] According to one embodiment of the present invention, the flexible pad and the adhesive layer are provided with communicating top surface vent holes.

[0008] According to one embodiment of the present invention, the flexible pad is provided with vent holes around its perimeter that communicate with the vent holes on the top surface.

[0009] According to one embodiment of the present invention, the bearing surface is provided with a limiting groove that limits and cooperates with the valve body of the three-way valve body.

[0010] According to one embodiment of the present invention, the depth of the limiting groove is not greater than the distance between the bottom end of the connector of the three-way valve body and the bottom end of the valve body.

[0011] According to one embodiment of the present invention, the limiting component includes a limiting band and a limiting post. One end of the limiting band is fixedly connected to the flexible pad, and the other end of the limiting band is fixedly provided with a limiting hook. The limiting hook is hooked and engaged with the limiting post. The limiting post is fixedly connected to the flexible pad. The three-way valve body is sandwiched between the limiting band and the flexible pad.

[0012] According to one embodiment of the present invention, a plurality of limiting posts are provided along the stretching direction of the limiting band.

[0013] According to one embodiment of the present invention, the distance between the limiting post and the bearing surface is not less than the thickness of the limiting hook.

[0014] According to one embodiment of the present invention, the three-way valve body is further provided with a rotating cap, the rotating cap including a fixedly disposed rotating handle and an indicator protrusion.

[0015] The advantages and beneficial effects of this utility model are as follows: The three-way valve fixing component of this utility model has a reasonable structure.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0019] like Figure 1-5 As shown, the catheter three-way valve fixation assembly of this embodiment includes a flexible pad 1, an adhesive layer 2, a three-way valve body 3, and a limiting component. To ensure a firm bond between the flexible pad 1 and the patient's skin, the adhesive layer 2 is fixedly disposed on the adhesive surface 11 of the flexible pad 1. The limiting component is used to fix the three-way valve body 3 to the bearing surface 12 of the flexible pad 1. The adhesive surface 11 and the bearing surface 12 are disposed opposite to each other. The flexible pad 1 isolates the three-way valve body 3 from the patient's skin, avoiding pressure damage to the patient's skin caused by the three-way valve body 3. The flexible pad 1 provides a cushioning effect.

[0020] To prevent the flexible pad 1 from becoming stuffy and causing allergic reactions or itching when adhered to the patient's skin, the flexible pad 1 and the adhesive layer 2 are provided with interconnected top surface ventilation holes 4. This improves the breathability of the flexible pad 4 and reduces the occurrence of stuffiness.

[0021] like Figure 1-3 As shown, a further improvement is that the flexible pad 1 is provided with circumferential ventilation holes 5 around its perimeter, which communicate with the ventilation holes 4 on the top surface. When airflow passes through the perimeter of the flexible pad 1, the breathability of the flexible pad 1 can also be achieved, further improving the breathability performance of the flexible pad 1.

[0022] According to one embodiment of the present invention, such as Figure 1-3 As shown, the bearing surface 12 is provided with a limiting groove 13 that limits and cooperates with the valve body 31 of the three-way valve body 3. The limiting groove 13 can provide positioning and limiting functions for the placement of the three-way valve body 3, so that the three-way valve body 3 can be quickly placed into position.

[0023] like Figure 3As shown, it is worth noting that the depth of the limiting groove 13 is not greater than the distance between the bottom end of the connector 32 and the bottom end of the valve body 31 of the three-way valve body 3. If the depth of the limiting groove 13 is greater than the distance between the bottom end of the connector 32 and the bottom end of the valve body 31, when the three-way valve body 3 is placed, the bottom end of the valve body 31 will not be able to contact the bottom of the limiting groove 13, and the bottom end of the connector 32 will interfere with the bearing surface 12, which will have a certain impact on the flow of the conduit; at the same time, it will also affect the fixed stability of the three-way valve body 3.

[0024] like Figure 1 Figure 2 Figure 4 As shown, according to one embodiment of the present invention, the limiting component includes a limiting band 6 and a limiting post 7. One end of the limiting band 6 is fixedly connected to the flexible pad 1, and the other end of the limiting band 6 is fixedly provided with a limiting hook 61, which hooks and engages with the limiting post 7. The limiting post 7 is fixedly connected to the flexible pad 1. The three-way valve body 3 is sandwiched between the limiting band 6 and the flexible pad 1. The three-way valve body 3 is placed in the limiting groove 13. The limiting band 6 is pulled from one end to the other end and hooks with the limiting post 7 through the limiting hook 61. The three-way valve body 3 is limited and pressed against the flexible pad 1 by the limiting band 6, thereby achieving the purpose of fixing the position of the three-way valve body 3.

[0025] like Figure 1 Figure 2 Figure 4 As shown, according to one embodiment of this utility model, several limiting posts 7 are arranged along the stretching direction of the limiting band 6. This design allows for appropriate adjustment of the fixing tightness of the three-way valve body 3, preventing excessive pressure on the three-way valve body 3 or the flexible pad 1 on the side of the limiting post 7 from being lifted when the fixing is too tight.

[0026] like Figure 4 As shown, according to one embodiment of this utility model, the distance between the limiting post 7 and the bearing surface 12 is not less than the thickness of the limiting hook 61. This design ensures that the limiting hook 61 can be smoothly engaged, avoiding the phenomenon that the limiting hook 61 cannot be engaged due to insufficient distance between the limiting post 7 and the bearing surface 12.

[0027] like Figure 5 As shown, according to one embodiment of the present invention, the three-way valve body 3 is further provided with a rotating cap 33, the rotating cap 33 including a fixedly disposed rotating handle 331 and an indicating protrusion 332. The operator only needs to operate the rotating handle 331 to realize the rotation of the rotating cap 33 and switch the passage of the valve core, and the indicating protrusion 332 can also clearly indicate the current passage status.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
