Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary appliances, and in particular to a wearable medical catheter fixing device. Background Art

[0002] Medical catheters are generally plastic tubes with a certain length at one end. According to their functional characteristics, medical catheters include ordinary catheters and special catheters. Among them, the shape and structure of special catheters are relatively complex.

[0003] For example, the venous catheter inserted into the peripheral vein is used to establish a long-term venous access for critically ill patients. Its output end is usually connected to an indwelling needle. In order to extend the service life of the indwelling needle, a heparin cap structure that can be repeatedly punctured for infusion and injection of drugs is usually connected between the venous catheter and the indwelling needle. After being assembled with different medical instruments, the structure of the venous catheter has changed, and the heparin cap structure generally needs to be fixed to avoid shaking. At present, most of the fixing methods of the heparin cap are fixed with adhesive tape or tape. Although the adhesive tape or tape can fix catheter structures of different structural sizes, there are also some shortcomings. For example, although the adhesive tape has a certain air permeability, it has poor viscosity. When the patient's puncture site swings or rubs, this type of adhesive tape may detach from the body surface, causing the heparin cap to shake or pull the indwelling needle; although the adhesive tape has strong viscosity, it has poor air permeability. If the patient is in poor physical condition, long-term use of the adhesive tape may cause skin discomfort to the patient, and the adhesive of the adhesive tape may also remain on the catheter and the patient's skin. The prior art discloses a heparin cap holder for an indwelling needle (authorization announcement number CN210992269U), which has the function of fixing the heparin cap to prevent the problem of difficulty in sterilizing the heparin cap caused by residual sticky colloid when the heparin cap is fixed with medical tape. However, the structure of the holder is only designed for a single medical catheter. As mentioned above, after the medical catheter is combined with other medical appliances, its structure and size will change, and the holder may not be able to fix other types of medical catheters. Utility Model Content

[0004] The technical problem to be solved by the present application is to provide a wearable medical catheter fixing device, which can fix medical catheters of different types, structures and sizes, heparin caps or other medical appliances connected to the medical catheters, and prevent the medical catheters and the corresponding medical appliances from being separated when connected and used.

[0005] In order to solve the above technical problems, this application adopts the following technical solutions:

[0006] A wearable medical catheter fixing device comprises a base, and the left and right ends of the base are provided with straps, a cushion layer is provided on the base, an adjustment rod is provided on the left side of the top of the base, and a fixing rod is provided on the right side, a swingable pressing plate assembly is provided on the adjustment rod, a deformable rib is provided at the bottom of the pressing plate assembly, a first adjusting member for adjusting the height of the pressing plate assembly and fixing the pressing plate assembly is provided on the adjustment rod, a notch is provided at the right end of the pressing plate assembly, and the fixing rod is located in the notch; and a second adjusting member for fixing the pressing plate assembly is provided on the fixing rod. The base is tied to the patient's hand by the strap, and then medical appliances such as medical catheters are placed on the cushion layer of the base, and the pressing plate assembly is covered, and then the notch of the pressing plate assembly is stuck on the fixing rod, and the second adjusting member is pressed above the notch to prevent the pressing plate assembly from bouncing off, and when the pressing plate assembly presses the medical catheter, the deformable rib and the medical catheter are in contact and deformed by pressure, so that the contact surface between the deformable rib and the medical catheter increases, and the friction force also increases, and the cushion layer is also deformed, and the deformable rib and the cushion layer provide corresponding friction to fix the medical catheter to prevent it from loosening. To adapt to medical catheters of different sizes, it is only necessary to adjust the first adjusting member upwards to move the pressing plate assembly upwards.

[0007] Compared with the prior art, the present application achieves at least the following beneficial effects: the fixing device is provided with a cushion layer and a deformable rib on the base and the bottom of the pressure plate assembly, and both are deformed when squeezed, thereby increasing the contact area and the friction force to fix the medical catheter, and the fixation stability is good; the pressure plate assembly can be adjusted in height on the adjusting rod through the first adjusting member, and medical catheters of different sizes, shapes, and structures, as well as medical devices such as heparin caps used in conjunction with the medical catheters, can be fixed.

[0012] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0013] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0014] The inventors have made a careful analysis and found that the main reason for the above problem is that the existing technology cannot fix medical catheters, heparin caps or other medical appliances connected to medical catheters of different types, structures and sizes.

[0015] The prior art discloses a heparin cap holder for an indwelling needle that can generally only be used to fix a few medical catheters that conform to the holder structure. As described in the present application, when a medical catheter is used in different situations, it will be connected to medical appliances of different structures and sizes. In this way, the end of the medical catheter that needs to be fixed not only has a different structure, but also has a different size. A holder that can only be used for a single catheter structure may not be able to meet the fixation requirements of medical catheters of different types and combinations. Based on the above analysis, the inventor has made structural improvements to the holder for fixing medical catheters.

[0016] Combination Figure 1 and Figure 2As shown, in one embodiment of a wearable medical catheter fixing device of the present application, the device includes a base 1, and straps 9 are provided at both ends of the left and right ends of the base 1 for tying on the patient's arm. A cushion layer 10 is provided on the base 1, and two vertical adjustment rods 4 are provided on the left side of the top of the base 1, and a vertical fixing rod 6 is provided on the right side. A swingable pressure plate assembly is provided on the adjustment rod 4, and a deformable rib 8 is provided at the bottom of the pressure plate assembly. A first adjustment member 2 for adjusting the height of the pressure plate assembly and fixing the pressure plate assembly is sleeved on the adjustment rod 4, and a U-shaped notch 5-1 is opened at the right end of the pressure plate assembly, and the fixing rod 6 is located in the notch 5-1; a second adjustment member 7 for fixing the pressure plate assembly is provided on the fixing rod 6. The base 1 is tied to the patient's arm through the strap 9, and then the medical catheter and other medical appliances are placed on the cushion layer 10 of the base 1, and the pressure plate assembly is covered. Then the notch 5-1 of the pressure plate assembly is stuck on the fixed rod 6, and the second adjustment member 7 is moved downward from the fixed rod 6 and pressed on the notch 5-1 to prevent the pressure plate assembly from bouncing. When the pressure plate assembly presses the medical catheter, the deformed ribs 8 and the medical catheter are in contact and deformed under pressure, so that the contact surface between the deformed ribs 8 and the medical catheter increases, and the friction force also increases. At the same time, the cushion layer 10 will also deform, and the deformed ribs 8 and the cushion layer 10 provide corresponding friction to fix the medical catheter and prevent it from loosening. If you want to adapt to medical catheters of different sizes, just adjust the first adjustment member 2 upward to move the pressure plate assembly upward.

[0017] The adjusting rod 4 and the fixing rod 6 are screw structures, and correspondingly, the first adjusting member 2 and the second adjusting member 7 are nuts, so that the first adjusting member 2 and the second adjusting member 7 can move on the adjusting rod 4 and the fixing rod 6 respectively. After reaching the specified position, the threaded connection can prevent the first adjusting member 2 and the second adjusting member 7 from moving up and down.

[0018] The function of the pressing plate assembly is to fix the medical catheter and the corresponding medical supplies connected to the medical catheter by pressing them. In order to facilitate the opening and pressing down of the pressing plate assembly, the pressing plate assembly includes a lifting plate 3 and a fixing plate 5, and the lifting plate 3 and the fixing plate 5 are hinged.

[0019] The lifting plate 3 is used to adjust the height of the pressure plate assembly. Therefore, two through holes corresponding to the two adjusting rods 4 are opened on the top surface of the lifting plate 3. The lifting plate 3 is movably sleeved in the adjusting rods 4 through the two through holes.

[0020] refer to Figure 2 The notch 5-1 of the pressure plate assembly is opened on the right end surface of the fixed plate 5. When the pressure plate assembly is pressed down, refer to Figure 1 , the notch 5 - 1 of the fixing plate 5 is stuck on the fixing rod 6 , and then the second adjusting member 7 is moved from top to bottom to press above the notch 5 - 1 , so that the fixing plate 5 can be restricted from rebounding.

[0021] There are two first adjusting members 2, which are respectively arranged above and below the lifting plate 3. When the pressure plate assembly needs to be adjusted to move upward, the first adjusting member 2 above the lifting plate 3 is first moved upward, and then the first adjusting member 2 below the lifting plate 3 is rotated and moved upward along the adjusting rod 4, and the first adjusting member 2 lifts the lifting plate 3. After the lifting plate 3 reaches a suitable position, the two first adjusting members 2 are tightened toward the lifting plate 3 to fix the lifting plate 3.

[0022] The cushion layer 10 is a rubber layer, specifically a silicone layer. When the medical catheter is under pressure, the medical catheter presses the cushion layer 10 downward, and the cushion layer 10 is deformed, thereby increasing the contact surface with the medical catheter and increasing the friction.

[0023] The material of the deformable rib 8 is elastic rubber, such as silicone. In this embodiment, a plurality of deformation holes are provided at the front end of the deformable rib 8. The purpose of providing the holes is that when the deformable rib 8 and the medical catheter are squeezed against each other, the surface of the deformable rib 8 is concave toward the deformation hole, the deformation is larger, the contact surface with the medical catheter is larger, and the fixation is more stable. In addition, the bottom of the deformable rib 8 is wavy, so some curved catheters can also be fixed.

[0024] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the protection scope of the present application.
