Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to an elastic fixing patch for a hemodialysis catheter. Background Art

[0002] Hemodialysis treatment is a common treatment for patients with end-stage renal failure. Clinically, when a patient needs hemodialysis treatment, the external connector of the hemodialysis catheter is connected to the connector of the extracorporeal circulation line, and the dialysis machine is started to filter the patient's blood. In order to protect the catheter connection from contamination during the treatment process, nursing staff usually need to use a sterile treatment towel (hereinafter referred to as the treatment towel) to wrap the external connector of the hemodialysis catheter and the connector of the extracorporeal circulation line that are connected as one, and use medical tape to stick the treatment towel to the patient's body for fixing. After completing the dialysis treatment, it is necessary to remove the treatment towel and medical tape, separate the external connector of the hemodialysis catheter from the connector of the extracorporeal circulation line and seal the tube. After sealing the tube, use medical gauze to roll up and wrap the external connector of the hemodialysis catheter, and use new medical tape to stick the medical gauze to the patient's body for fixing. The problem with this solution is that the duration of dialysis treatment is usually long, and using medical tape to stick the treatment towel to the patient's skin for a long time may cause allergies and discomfort to the patient. At the same time, the medical tape needs to be removed and a new one needs to be applied after each dialysis treatment. For patients who undergo long-term dialysis treatment, the repeated sticking and tearing of the medical tape will cause certain damage to the patient's skin. Therefore, how to develop a new fixing device that can overcome the above problems in the prior art is a direction that technicians in this field need to further study. Utility Model Content

[0003] The utility model aims to provide an elastic fixing patch for a hemodialysis catheter, which can reduce allergies caused by long-term use of medical adhesive tape during dialysis treatment and reduce the damage caused by the medical adhesive tape to the patient's skin.

[0004] The utility model provides an elastic fixing patch for a hemodialysis catheter, which comprises:

[0005] A first fixed wing, a middle layer and a second fixed wing connected in sequence;

[0006] The first fixing wing and the second fixing wing are symmetrically connected to the two ends of the middle layer; the first fixing wing and the second fixing wing are respectively provided with an adhesive layer;

[0007] The middle layer includes an elastic film layer, and the elastic film layer is configured to be in a planar structure in a natural state (ie, when not pulled by an external force).

[0008] By adopting this technical solution: the first fixing wing and the second fixing wing are used to fix the elastic fixing patch of the hemodialysis catheter to the position of the patient's body surface near the indwelling tube. During the dialysis treatment, the external connector of the hemodialysis catheter is connected to the connector catheter of the extracorporeal circulation pipeline, and the external connector of the hemodialysis catheter and the connector of the extracorporeal circulation pipeline that are connected as one are wrapped with a treatment towel, and the treatment towel wrapped with the external connector of the hemodialysis catheter and the connector of the extracorporeal circulation pipeline is adhered to the upper surface of the elastic film layer with medical tape to play a fixing role. At this time, the elastic film layer replaces the direct contact between the skin and the external part of the hemodialysis catheter, alleviating the patient's skin allergy problem caused by this. After the dialysis treatment is completed, the medical tape is removed from the upper surface of the elastic film layer, the wrapped treatment towel is unwrapped, the external connector of the hemodialysis catheter is separated from the connector of the extracorporeal circulation pipeline and the tube is sealed. After the tube is sealed, the external connector of the hemodialysis catheter is rolled up and wrapped with medical gauze, the elastic film layer is pulled upward, and the medical gauze wrapped with the external connector of the hemodialysis catheter is placed between the elastic film layer and the human skin. Therefore, there is no need to repeatedly stick and tear off the medical tape on the human skin, which reduces the damage to the patient's skin.

[0009] Preferably, the first fixing wing and the second fixing wing are respectively made of anti-allergic silicone material.

[0010] By adopting this technical solution, the hidden danger of allergies caused by the first fixed wing and the second fixed wing sticking to the surface of human skin for a long time can be avoided.

[0011] Preferably, the intermediate layer further comprises a cushion layer, and the cushion layer is a planar structure arranged below the elastic membrane layer, and there is a gap between the upper surface of the cushion layer and the lower surface of the elastic membrane layer.

[0012] By adopting this technical solution: during dialysis treatment, the elastic membrane layer is naturally flat, and the external connector of the hemodialysis catheter is wrapped with a treatment towel and placed between the elastic membrane layer and the cushion layer. This prevents the treatment towel wrapped with the external connector of the hemodialysis catheter from directly contacting the human skin, reduces the pressure on this part of the human skin, and improves the comfort of the patient.

[0013] Preferably, the cushion layer has a rectangular structure, and a placement groove is provided in the middle of the cushion layer.

[0014] By adopting this technical solution: after completing the dialysis treatment, the elastic membrane layer is pulled upwards, and the external part of the catheter is wrapped with medical gauze and placed in the groove.

[0015] Preferably, a pulling ring is fixedly connected to the upper surface of the elastic membrane layer.

[0016] By adopting this technical solution: after completing the dialysis treatment, the elastic membrane layer is pulled upward by the pulling ring, making the process of pulling the elastic membrane layer upward more convenient.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] Firstly, the utility model can reduce direct contact between the pipeline wrapped by the treatment towel and the skin during dialysis treatment, thereby alleviating skin discomfort.

[0019] Secondly, the utility model can reduce the damage caused by the medical adhesive tape to the patient's skin.

[0020] Finally, the utility model has a simple structure, a simple operation process, and is easy for medical staff to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] Example 1, please refer to Figure 1-3 :

[0031] A hemodialysis catheter elastic fixing patch comprises: a first fixing wing 100, a middle layer 200 and a second fixing wing 300 which are connected in sequence.

[0032] The first fixing wing 100 and the second fixing wing 300 have the same shape, and are symmetrically mounted on the left and right ends of the middle layer 200; the lower sides of the first fixing wing 100 and the second fixing wing 300 are respectively provided with an adhesive layer 400; in practice, an oil paper that is easy to tear off can be provided on the surface of the adhesive layer 400. The first fixing wing 100 and the second fixing wing 300 are respectively made of anti-allergic silicone material.

[0033] The middle layer 200 includes an elastic film layer 210 , which is configured to be a planar structure when in a natural state. When the elastic film layer 210 is pulled in a certain direction, the elastic film layer 210 will generate corresponding elastic deformation in the pulled direction.

[0034] In practice, the working process is as follows:

[0035] First, the adhesive layer 400 is used to fix the hemodialysis catheter elastic fixing patch to the patient's body surface near the external connector 600 of the hemodialysis catheter through the first fixing wing 100 and the second fixing wing 300, and the elastic film layer 210 is in a natural state (that is, the elastic film layer 210 is unfolded and attached to the surface of the patient's skin 800).

[0036] Please refer to Figure 2 During the dialysis treatment, the external connector of the hemodialysis catheter is connected to the connector of the extracorporeal circulation pipeline as a whole, and the external connector of the hemodialysis catheter and the connector of the extracorporeal circulation pipeline that are connected as a whole are wrapped with a treatment towel 500, and the treatment towel 500 wrapped with the external connector of the hemodialysis catheter and the connector of the extracorporeal circulation pipeline is adhered to the upper surface of the elastic film layer 210 with a medical adhesive tape 700. The elastic film layer 210 directly contacts the above-mentioned pipeline part wrapped by the treatment towel 500 instead of the skin 800, which alleviates the discomfort of the patient's skin 800.

[0037] Please refer to Figure 3After the dialysis treatment is completed, the medical tape 700 is removed from the upper surface of the elastic film layer 210, the wrapped treatment towel 500 is unwrapped, the external connector 600 of the hemodialysis catheter is separated from the connector of the extracorporeal circulation pipeline and the tube is sealed. After the tube is sealed, the external connector 600 of the hemodialysis catheter is rolled up and wrapped with medical gauze 610, the elastic film layer 210 is pulled upward, and the medical gauze 610 wrapped with the external connector 600 of the hemodialysis catheter is placed in the space between the elastic film layer 210 and the human skin 800. The elastic film layer 210 is moved away to reset itself, so that the lower side of the elastic film layer 210 presses down the medical gauze 610 that wraps the external connector 600 of the hemodialysis catheter, thereby eliminating the need to use the medical tape 700 to fix the medical gauze 610 on the patient's skin 800. Therefore, this solution does not require repeated sticking and tearing of the medical tape 700 on the human skin 800, thereby reducing damage to the patient's skin 800.

[0038] like Figure 4-5 Example 2 is shown:

[0039] The difference between Example 2 and Example 1 is that in this example:

[0040] The intermediate layer 200 further includes a cushion layer 220, which is a rectangular surface structure disposed below the elastic film layer 210, and there is a gap between the upper surface of the cushion layer 220 and the lower surface of the elastic film layer 210. That is, when the elastic film layer 210 is in a natural state, the lower surface of the elastic film layer 210 is in contact with the upper surface of the cushion layer 220; when the elastic film layer 210 is pulled upward, the elastic film layer 210 will be arched upward accordingly, and at this time, part of the lower surface of the elastic film layer 210 is separated from the upper surface of the cushion layer 220. Further preferably, in this example: the cushion layer 220 is a rectangular sheet structure, and a placement groove is provided in the middle of the cushion layer 220.

[0041] In practice, the working process is as follows:

[0042] During the dialysis treatment, the operation process of sticking the treatment towel wrapped with the external connector 600 of the hemodialysis catheter and the connector of the extracorporeal circulation line to the upper surface of the elastic film layer through the medical adhesive tape is the same as that in Example 1. After the dialysis treatment is completed, the medical adhesive tape 700 is removed from the upper surface of the elastic film layer 210, the treatment towel 500 is untied, the external connector 600 of the hemodialysis catheter and the connector of the extracorporeal circulation line are separated, the external connector 600 of the hemodialysis catheter is wrapped with the medical gauze 610, the elastic film layer 210 is pulled upward, and the medical gauze 610 wrapped with the external connector 600 of the hemodialysis catheter is placed in the placement groove on the cushion layer 220, and the elastic film layer 210 is pushed away to reset it, so that the lower side of the elastic film layer 210 presses down the medical gauze 610 wrapped with the external connector 600 of the hemodialysis catheter. The height of both sides of the placement groove is substantially flush with the upper side of the medical gauze 610 that is located in the placement groove and wraps the external connector 600 of the hemodialysis catheter, thereby reducing the pressure of the elastic membrane layer 210 on the medical gauze 610 .

[0043] like Figure 6 Example 3 is shown:

[0044] The difference between Example 3 and Example 2 is that, in this example, a pulling ring 230 is fixedly connected to the upper surface of the elastic membrane layer 210. In this example, the pulling ring 230 is configured as two, and the two pulling rings 230 are symmetrically distributed on the upper surface of the elastic membrane layer 210. In practice, after the dialysis treatment is completed, the elastic membrane layer 210 is pulled upward by the pulling ring 230.

[0045] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
