Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an armband structure for fixing a catheter and a heparin cap. Background Art

[0002] Catheters with different functions are often used in hospitals, such as peripherally placed central venous catheters, which are used to establish long-term venous access for critically ill patients. One end of the catheter is connected to an indwelling needle. In order to extend the service life of the intravenous needle, a heparin cap is connected between the catheter and the needle. The heparin cap can be used in conjunction with the arteriovenous indwelling needle, and can be punctured multiple times for infusion and injection of drugs. This not only reduces the cost of frequent replacement of medical equipment, but also improves the work efficiency of medical staff.

[0003] The current fixation method for peripherally placed central venous catheters and heparin caps is relatively simple and traditional. For example, after a successful puncture, medical tape, dressings or transparent tape are used for fixation. This simple and traditional fixation method has some shortcomings. First, although the medical tape has a certain degree of air permeability, its viscosity is relatively weak. When the patient's body swings or rubs, the medical tape with less viscosity may fall off, causing the catheter to shake, which may eventually cause traction on the indwelling needle. If the heparin cap is lower than the puncture point during the shaking process, blood may return; although the transparent tape has strong viscosity, its air permeability is poor. Long-term use may cause adverse effects such as skin discomfort or even ulceration in the patient. At the same time, tearing off the transparent tape will also irritate the patient's skin, which is not conducive to the patient's treatment. Utility Model Content

[0004] The technical problem to be solved by the present application is to provide an armband structure for fixing a catheter and a heparin cap, which can ensure that the peripherally placed central venous catheter and the pipeline connected to the heparin cap and the indwelling needle are stably connected, and at the same time, it can stably fix these structures on the patient's body surface while ensuring a certain degree of air permeability and viscosity, so as to prevent the catheter from shaking or falling off when the patient swings or rubs his body.

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

[0006] An armband structure for fixing a catheter and a heparin cap comprises a fixing airbag, connecting edges are respectively arranged on both sides of the fixing airbag, and the armband is movably connected to the two connecting edges, the armband comprises an elastic section and a fixing section, the end of the elastic section away from the fixing airbag is connected to the fixing section, an adhesive layer is arranged at the bottom of the fixing section, the fixing airbag presses and fixes the pipeline connecting the peripherally placed central venous catheter, the heparin cap and the indwelling needle, and is adhered to the patient's body surface through the adhesive layer on the armband.

[0007] In order to fix the airbag so that the external central venous catheter, the heparin cap and the indwelling needle can be stably connected in sequence, in some embodiments, a fixing groove is opened at the bottom of the fixing airbag, and the connection points of the peripherally placed central venous catheter, the heparin cap and the indwelling needle are respectively placed in the corresponding grooves to prevent loosening.

[0008] In order to enable the elastic section to be movably connected to the connecting edge that fixes the airbag, in some embodiments, the elastic section includes a flat belt head and an elastic flat belt, and the flat belt head is movably connected to the connecting edge.

[0009] In some embodiments, the movable connection is a hinge.

[0010] To facilitate removal and replacement of the armband, in some embodiments, the hinge is a snap connection.

[0011] In some embodiments, the fixing section is a Velcro structure, including a hook surface layer and a fleece surface layer, and the hook surface layer is connected to the elastic section.

[0012] In some embodiments, the adhesive layer is disposed on the bottom front side and the bottom back side of the fleece layer.

[0013] Compared with the prior art, the present application achieves at least the following beneficial effects: the armband structure uses a fixed airbag with a fixed groove to stably connect the connection points of the peripherally placed central venous catheter, heparin cap and indwelling needle pipeline, and is fixed to the patient's body surface with an armband with an adhesive function to prevent the catheter from shaking due to the patient's body swing, resulting in pipeline separation, and ensure that the heparin cap is stably arranged above the puncture point to avoid blood return; secondly, the armband structure of the utility model is used, which can predict or slow down the binding force through the elastic section to avoid the heparin cap from pressing on the skin due to excessive binding force; the use of an adhesive layer can not only improve the adhesion effect, but also reduce the adhesion area, improve air permeability, and reduce the patient's skin from being breathable for a long time and causing discomfort or ulceration.

[0018] 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.

[0019] 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.

[0020] The defects in the prior art are that the fixing method of the peripherally placed central venous catheter and the heparin cap is not stable enough, the use of medical tape is easy to cause the catheter to shake and be pulled loose when the patient's body swings, and the use of transparent tape has poor air permeability. After careful analysis, the inventors found that the main reason for the above problems is that the medical tape has good air permeability but poor adhesion. Usually, the use cycle of peripherally placed central venous catheters and heparin caps is several working days or even longer. During this period, the patient's body will move and rub to some extent. When the medical tape has poor adhesion, it is easy to fall off the patient's body surface, causing the intravenous catheter and the heparin cap to move. Therefore, medical staff need to frequently look after the patient and check the fixation of the intravenous catheter and the heparin cap on the patient's body surface; secondly, although the transparent tape has strong adhesion and can fix the intravenous catheter and the heparin cap, the material of the transparent tape determines its poor air permeability, which can easily cause the patient's skin to be airtight, thereby causing the skin to deteriorate or even ulcerate. At the same time, tearing off the transparent tape will also involve the patient's skin, which is not very friendly to the patient. In addition, the adhesive on the transparent tape may also remain on the surface of the intravenous catheter and the heparin cap during the tearing process. The residual adhesive will absorb some impurities and the cleanliness will also deteriorate. Based on the above analysis, the inventors have improved the fixing mechanism of the pipeline connecting the peripherally placed central venous catheter sequence and the heparin cap and the indwelling needle.

[0021] like Figure 1As shown, in one embodiment of an armband structure for fixing a catheter and a heparin cap of the present application, the armband structure includes a rectangular fixing airbag 1, a side wall of the fixing airbag 1 is provided with an inflation port 1-1, two sides of the fixing airbag 1 are respectively provided with plastic connecting edges 1-2, and the two connecting edges 1-2 are respectively movably connected with an armband, the armband includes an elastic section and a fixing section 4, the end of the elastic section away from the fixing airbag 1 is connected to the fixing section 4, and an adhesive layer 5 is provided at the bottom of the fixing section 4, the fixing airbag 1 presses and fixes the pipeline connected to the peripherally placed central venous catheter, the heparin cap and the indwelling needle, and is adhered to the patient's body surface through the adhesive layer 5 on the armband to prevent the movement of medical devices such as the catheter.

[0022] In order to enable the fixing airbag 1 to stably connect the pipelines of the external central venous catheter sequence, the heparin cap and the indwelling needle, the bottom of the fixing airbag 1 is provided with opening fixing grooves 1-3 which respectively match the connection ends of the external central venous catheter sequence, the heparin cap and the indwelling needle, and the connection points of the peripherally placed central venous catheter, the heparin cap and the indwelling needle are respectively placed in the corresponding grooves to prevent loosening.

[0023] In order to enable the elastic section to be movably connected to the connecting edge 1-2 of the fixed airbag 1, the elastic section includes a flat belt head 2 and an elastic flat belt 3. The flat belt head 2 and the connecting edge 1-2 are movably connected. The flat belt head 2 is a plastic sheet with a certain thickness and a width equal to or slightly wider than the elastic flat belt 3. The flat belt head 2 and the elastic flat belt 3 can be connected using glue. The purpose of setting the elastic section is that if the armband is directly tied to the patient's body, a large force may cause the fixed airbag 1 and the heparin cap to excessively compress the skin, causing blood circulation. After the elastic section is set, when a large force is applied, the elastic section will resist the direction of the force, so that medical staff can know the force situation and adjust the force size; in addition, the elastic section can also appropriately extend the length of the armband to adapt to different positions of the body for fixation.

[0024] The connection between the elastic section and the connecting edge 1-2 is hinged. Of course, in order to facilitate the removal and replacement of the armband, the hinge can be selected as a snap connection, that is, a hole is opened on the connecting edge 1-2, and a hole is also opened on the flat belt head 2 of the elastic section, and it is coaxial with the hole opened on the connecting edge 1-2. A snap 6 is arranged in the coaxial hole. When the elastic section loses its elasticity, the snap 6 can be removed to replace the armband, as shown in the attached Figure 1 As shown, the snap buttons 6 are arranged in groups of at least two.

[0025] refer to Figure 2 The fixing section 4 is a Velcro structure, including a hook surface layer 4-1 and a fleece surface layer 4-2, and the hook surface layer 4-1 and the elastic flat belt 3 of the elastic section can be sewed together.

[0026] The adhesive layer 5 is disposed at the bottom of the fleece layer 4 - 2 .

[0027] In order to improve the breathability, the adhesive layer 5 can be arranged on the bottom front and bottom back of the fleece layer 4-2, that is, the middle part is left empty. This reduces the adhesive area and improves the breathability while ensuring the adhesive effect, thus reducing the possibility of skin ulceration caused by long-term airtightness of the patient.

[0028] The adhesive layer 5 is made of adhesive, and the specific material thereof refers to the adhesive on the stoma bottom plate.

[0029] When in use, first inflate the fixed airbag 1. When the fixed airbag 1 is inflated, the shape is as follows: Figure 1 and Figure 2 As shown, the connection points of the peripherally placed central venous catheter, the heparin cap and the indwelling needle are respectively snapped into the fixing grooves 1-3 at the bottom of the fixing airbag 1, and then the adhesive layer 5 at the bottom of the fixing section 4 is fitted and fixed to the patient's body surface; if the armband is shorter, such as Figure 2 As shown, the elastic section can be properly lengthened or the fleece layer 4-2 of the fixed section 4 can be torn off and staggered with the hook layer 4-1, so that the armband will become longer and can adapt to patients of different body shapes.

[0030] When the adhesive layer 5 is not sticky enough, the fleece layer 4-2 can be directly replaced. When the elasticity of the elastic flat belt 3 of the elastic section is not elastic enough, the snap button 6 can be removed to replace the hook layer 4-1 of the elastic section and the fixed section 4, thereby reducing the replacement cost.

[0031] 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 based on the concept of the present application should all be within the protection scope of the present application.
