Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a fixation device for a gastric tube insertion catheter. Background Technology

[0002] Gastric tube insertion is a commonly used clinical medical procedure, playing an irreplaceable role in gastrointestinal decompression, enteral nutrition, and drug infusion. In general, after the initial fixation of the catheter, it needs to be repositioned and secured again near the initial fixation point or at another suitable location. The initial fixation is to establish the relationship between the catheter and the patient, ensuring the catheter can be correctly and stably inserted into the stomach. The secondary fixation ensures a good connection between the catheter and the patient, preventing displacement or even dislodgement during use.

[0003] Currently, the most common method in clinical practice is to use existing medical tape to fix the catheter to the patient's skin. However, the reliability of using tape to fix the catheter is poor, especially the connection between the tape and the catheter is unreliable. Over time, the tape may detach from the catheter, allowing the catheter to rotate or slide relative to the connection between the tape and the catheter. Therefore, medical staff need to continuously monitor and frequently replace the fixing tape. Otherwise, there is a risk that the catheter may detach from the tape, leading to accidental removal (displacement or dislodgement).

[0004] Therefore, there is an urgent need for a new solution to overcome the problem of unreliable connection between the tape and the catheter that easily occurs when the catheter is fixed to the patient's skin directly with medical tape in the existing technology. Utility Model Content

[0005] The purpose of this application is to propose a fixation device for a gastric tube insertion catheter, which solves the problem of unreliable connection between the tape and the catheter that easily occurs when the catheter is directly fixed to the patient's skin with medical tape in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A fixation device for a gastric tube insertion catheter includes: a base patch; a fixation piece disposed on the back of the base patch along the length of the fixation piece, wherein a non-connected clearance section is provided between the fixation piece and the base patch, and the side of the fixation piece away from the base patch has a raised structure for increasing friction; a malleable support strip disposed on the fixation piece and extending along the width of the fixation piece; and a binding strip disposed perpendicular to the length of the fixation piece, the binding strip being capable of wrapping around the clearance section along the width of the fixation piece to bind the fixation piece.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the two ends of the fixing piece along the length direction are fixedly connected to the base patch, and the middle section that is not connected to the base patch is the avoidance section.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the fixing piece is a groove structure that extends integrally along the length direction, and the bottom side of the groove structure is connected to the base patch.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the distance from one side of the fixing piece in the width direction to the bottom side of the groove structure is less than the distance from the other side to the bottom side of the groove structure.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the malleable support strips are respectively disposed at both ends of the fixed piece along its length.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the malleable support strip is embedded inside the fixing piece.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the binding strip is provided on one side of the width direction of the fixing piece, one end of the binding strip is connected to the fixing piece, and the other end extends freely outward; the side of the binding strip away from the direction of the base patch is provided with a barb structure.

[0014] Based on the above solution and as a preferred embodiment of the above solution: the protrusion structure includes dot-shaped protrusions protruding away from the base patch, and the dot-shaped protrusions are arranged on the entire surface of the fixing piece.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: the top of the dot-shaped protrusion away from the direction of the fixing piece has an outward convex tip structure.

[0016] Based on the above scheme and as a preferred embodiment of the above scheme: the tip of the top structure is desharpened.

[0017] To address the problem of unreliable connection between the adhesive tape and the catheter that easily occurs when directly fixing the catheter to the patient's skin using medical tape in the prior art, this application has the following beneficial effects:

[0018] The gastric tube insertion catheter fixation device of this application is mainly used for secondary fixation of the gastric tube insertion catheter. In use, the base patch is adhered and fixed to the patient's skin. Then, the catheter is placed on the side of the fixation patch away from the base patch, parallel to the length of the catheter. The fixation patch is then rolled up so that it surrounds the catheter in the width direction. Finally, the fixation patch is wrapped and tied from the avoidance section using a binding strip, thereby completing the secondary fixation of the catheter.

[0019] During the process of binding with the binding strip, the protruding structure of the fixing plate is in full contact with the catheter. The force applied by the binding strip makes the protruding structure act better on the catheter, so that the catheter can be reliably connected with the fixing plate. Even if the catheter is subjected to external force, there will be no slippage or separation between the catheter and the fixing plate, thus avoiding catheter displacement or detachment due to unreliable secondary fixation.

[0020] In this process, since the fixing piece needs to be wrapped around the conduit before applying the binding strip, to prevent it from unwinding during the binding process, a malleable support strip is coiled around the conduit to shape it. This coiling motion helps the fixing piece wrap around the conduit and maintain its encirclement. This makes the binding process much easier and faster, requiring no assistance from a third person and can be easily completed by one person.

[0021] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0035] See Figure 1-8 This application discloses a fixation device for gastric tube insertion, mainly used for secondary fixation of the gastric tube insertion catheter 600. The fixation device mainly includes a base patch 100, a fixation piece 200, a malleable support strip 300, and a binding strip 400. The catheter 600 is connected through the fixation piece 200 to achieve a reliable connection of the catheter 600 during secondary fixation, ensuring a good connection between the catheter 600 and the patient, and avoiding displacement or even dislodgement of the catheter 600 during use.

[0036] In this embodiment of the disclosure, the gastric tube insertion fixation device includes a base patch 100, a fixation piece 200, a malleable support strip 300, and a binding strip 400.

[0037] The base patch 100 has an adhesive side, allowing it to be directly applied to the patient's skin for fixation. Typically, the adhesive side of the base patch 100 is protected by a peelable protective patch 101. The base patch 100 is preferably made of hydrocolloid dressing, which offers advantages such as skin affinity, strong adhesion, resistance to loosening, low allergenicity, and no adhesive residue after use. Of course, other medical adhesive tapes can also be used for the base patch 100. In some procedures, including but not limited to, methods such as wrapping more tape around the patient's body or increasing the adhesion area can be used to further secure the base patch 100. Furthermore, the base patch 100 can be designed in an oval shape to prevent curling and peeling, resulting in a neat and aesthetically pleasing appearance, hygienic application, ease of use, and improved work efficiency.

[0038] Among them, such as Figure 1-5 As shown, the fixing piece 200 is disposed on the back of the base patch 100, i.e., on the side away from the adhesive. Along the length of the fixing piece 200, a non-connected clearance section 201 is provided between the fixing piece 200 and the base patch 100. In the clearance section 201, the fixing piece 200 and the base patch 100 are separable. The side of the fixing piece 200 away from the base patch 100 is provided with a raised structure 202 to increase friction. When setting the conduit 600, the conduit 600 is placed along the length of the fixing piece 200 on the side of the fixing piece 200 where the raised structure 202 is provided. Then, the fixing piece 200 is rolled up along the width of the fixing piece 200, so that the fixing piece 200 surrounds the conduit 600 and the raised structure 202 is in full direct contact with the conduit 600.

[0039] Among them, such as Figure 1 and Figure 4As shown, a malleable support strip 300 is disposed on the fixing piece 200 and extends along the width direction of the fixing piece 200. The main function of the malleable support strip 300 is to constrain the fixing piece 200. When the fixing piece 200 is wound around the guide rail, the malleable support strip 300 can be shaped simultaneously, allowing the malleable support strip 300 to bend around the outside of the conduit 600, thereby maintaining the fixing piece 200 on the conduit 600 in a manner that surrounds the outer surface of the conduit 600. The malleable support strip 300 can be disposed on the outer surface of the fixing piece 200, such as the side near the base patch 100 or the side away from the base patch 100. Preferably, the malleable support strip 300 is directly embedded inside the fixing piece 200, extending along the width direction of the fixing piece 200 in the length direction.

[0040] The binding strip 400 is arranged perpendicular to the length direction of the fixing piece 200, and the binding strip 400 can wrap around the clearance section 201 along the width direction of the fixing piece 200 to bind the fixing piece 200.

[0041] In use, the base patch 100 is adhered and fixed to the patient's skin. Then, the catheter 600 is placed parallel to the fixation patch 200 along its length, on the side of the fixation patch 200 away from the base patch 100. The fixation patch 200 is then rolled up so that it surrounds the catheter 600 in the width direction. Finally, the fixation patch 200 is wrapped and tied from the avoidance section 201 using the binding strip 400, thus completing the secondary fixation of the catheter 600.

[0042] During the process of binding with the binding strip 400, the protruding structure 202 of the fixing piece 200 is in full contact with the conduit 600. The force applied by the binding strip 400 makes the protruding structure 202 act better on the conduit 600, so that the conduit 600 can be reliably connected with the fixing piece 200. Even if the conduit 600 is subjected to external force, there will be no slippage or separation between the conduit 600 and the fixing piece 200, thereby avoiding the conduit 600 from shifting or falling out due to unreliable secondary fixation.

[0043] In this process, since the fixing piece 200 needs to be wrapped around the conduit 600 before securing the binding strip 400, to prevent the fixing piece 200 from unwinding during the binding process, a malleable support strip 300 is coiled around the conduit 600 to shape it. This coiling motion of the support strip 300 helps the fixing piece 200 to wrap around the conduit 600 and maintain its current encirclement. This makes the binding process much easier and faster, requiring no third-party assistance and can be easily completed by a single person.

[0044] The binding strip 400 can be implemented in various ways.

[0045] In some implementations, such as Figure 1-2 As shown, the binding strip 400 is an independent strip-shaped object, such as freely arranged cloth tape or adhesive tape. In use, after the fixing plate 200 is wrapped around the conduit 600 to complete the enclosure, the binding strip 400 wraps around the conduit 600 from the clearance section 201, either single-handedly or continuously, tightly binding the binding strip 400 to the outside of the fixing plate 200. By forcefully tightening the fixing plate 200 with the binding strip 400, the conduit 600 and the protruding structure 202 on the fixing plate 200, which increases friction, are made into full and reliable contact. Then, the binding strip 400 is knotted and secured. If disassembly is required, the binding strip 400 can be loosened for disassembly, or the entire strip can be replaced. However, the issues of being unable to disassemble or having an unreliable connection, which can occur with direct binding with adhesive tape, will not occur.

[0046] In some implementations, such as Figure 3-5 As shown, the binding strip 400 is directly set on the fixing piece 200, or it is integrated with the fixing piece 200. The binding strip 400 is set on one side of the fixing piece 200 in the width direction. One end of the binding strip 400 is fixedly connected to the fixing piece 200, and the other end extends freely outward. The side of the binding strip 400 away from the base patch 100 is provided with a barb structure 401. When binding with the binding strip 400, pull the end of the binding strip 400 away from the fixing piece 200 by hand, and then wrap the binding strip 400 around the fixing piece 200 and the guide tube 600. When wrapping, it is necessary to consider using force to make the protruding structure 202, which increases the friction, fit tightly against the outer wall of the guide tube 600. During the wrapping process, the barb structure 401 will penetrate into the outer surface of the fixing piece 200 or the side of the binding strip 400 away from the barb structure 401, forming a firm fixation of the binding strip 400. Furthermore, a suitable length can be set for the binding strip 400, such as wrapping it around the conduit 600 2-5 times to ensure the reliability of the binding.

[0047] Furthermore, such as Figure 3As shown, the barb structure 401 is provided with a spike structure 402 protruding from the surface of the binding strip 400, and the end of the spike structure 402 is inclined towards the side where the fixing piece 200 is located. During the winding process, the barb structure 401 adheres to the surface of the binding strip 400, and the spike structure 402 can pierce and hook into the surface of the binding strip 400 to form a fixation. Preferably, the binding strip 400 has a certain degree of elasticity. If it is necessary to disassemble the connection to the conduit 600, the binding strip 400 can be pulled in the tightening direction so that the barb structure 401 is removed from the binding strip 400 or the fixing piece 200, thereby realizing the disassembly of the conduit 600.

[0048] In some implementations, such as Figure 8 As shown, after the catheter 600 is tied, medical transparent tape 500 can be attached to the back of the base patch 100 to cover the fixing patch 200 and other connecting structures. This transparent tape 500 can protect the tying structure, prevent external forces from frequently touching the tying structure, and also facilitate visual observation of the connection of the tying structure.

[0049] In some implementations, such as Figure 4 , Figure 5 As shown, the end of the binding strip 400 away from the fixing piece 200 is also provided with a blank section 403 without a barb structure 401 at one end. Therefore, during the process of wrapping the binding strip 400, the blank section 403 can be held by hand to wrap it, preventing the barb structure 401 from scratching the skin of the medical staff's hands.

[0050] In some embodiments, the fixing piece 200 and the binding strip 400 are made of elastic silicone material, while the protruding structure 202 and the barbed structure 401 can be made of hard silicone material. During manufacturing, the protruding structure 202 and the barbed structure 401 of hard silicone can be molded in one step on the mold, and then the elastic fixing piece 200 and the binding strip 400 can be molded in a second step.

[0051] In some embodiments, in order to achieve a better surrounding effect of the fixation piece 200 on the conduit 600, the hardness of the fixation piece 200 should be greater than the hardness of the binding strip 400.

[0052] In the embodiments of this disclosure, such as Figure 1 , Figure 4As shown, the two ends of the fixing piece 200 along its length are fixedly connected to the base patch 100, and the middle section not connected to the base patch 100 is the avoidance section 201. Then, the binding strip 400 can bind the conduit 600 and the fixing piece 200 at the middle section of the fixing piece 200. After the conduit 600 is fixed in this way, both ends of the fixing piece 200 are connected to the base patch 100, resulting in a more even distribution of force on the base patch 100 and avoiding localized tensile stress on the base patch 100. At the same time, the malleable supports can be respectively set at both ends of the fixing piece 200 along its length. The malleable supports at both ends of the fixing piece 200 form a constraint effect when the fixing piece 200 is wrapped around the conduit 600, resulting in a more ideal constraint effect and a more convenient binding operation.

[0053] In the embodiments of this disclosure, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the fixing piece 200 is a groove structure 205 extending integrally along its length, and the bottom side (near the groove) of the groove structure 205 is connected to the base patch 100. Firstly, the fixing piece 200 of the groove structure 205 makes it easier to align and position the guide rail parallel to the length direction of the fixing piece 200 on the fixing piece 200. It also facilitates the winding operation of the fixing piece 200. Secondly, the portion of the fixing piece 200 that connects to the base patch 100 is close to the middle of its width, which also facilitates winding the fixing piece 200 onto the guide tube 600.

[0054] Furthermore, such as Figure 3 , Figure 4 As shown, to achieve a better and more convenient operating structure, the distance S1 from one side of the fixing piece 200 to the bottom side of the groove structure 205 in the width direction is less than the distance S2 from the other side to the bottom side of the groove structure 205. That is, the side with a distance of S1 is the short side, and the other side is the long side. When wrapping the fixing piece 200 around the conduit 600, first wrap the short side against the conduit 600, generally setting the length of the short side to about half a turn around the conduit 600. Then, use the long side to tilt towards the short side and continuously wrap around the conduit 600. Generally, the residual wrapping distance of the long side is set to about half a turn to one turn, and simultaneously use the binding strip 400 for binding.

[0055] In some embodiments, the groove structure 205 can be obtained by bending and shaping the fixing piece 200 in the width direction. It can be a V-shaped structure or a U-shaped structure, and of course, the optimal structure is... Figure 6 and Figure 7 The U-shaped structure shown is as follows: Figure 7As shown, after the conduit 600 is placed in the groove structure 205, the outer wall of the conduit 600 can naturally form contact with the side of the fixing piece 200 where the protrusion structure 202 is provided. The groove of the groove structure 205 can initially constrain the position of the conduit 600, making it easier to bend and shape the malleable support strip 300, which is beneficial for the subsequent operation of wrapping the fixing piece 200 around the conduit 600.

[0056] In the embodiments of this disclosure, such as Figure 1 , Figure 3 As shown, the protruding structure 202 includes dot-shaped protrusions 203 protruding away from the base patch 100, and the dot-shaped protrusions 203 are densely arranged on the entire surface of the fixing piece 200. When the protruding structure 202 is attached to the conduit 600 and subjected to external force, the dot-shaped protrusions 203 can embed into the outer surface of the conduit 600 to achieve engagement, thereby obtaining a stable and reliable connection. Furthermore, in order to facilitate the smooth occurrence of the engagement, the tip of the dot-shaped protrusion 203 in the direction away from the fixing piece 200 is an outwardly convex tip structure 204 (with a certain taper). Furthermore, the tip of the tip structure 204 needs to be desharpened to prevent the tip structure 204 of the dot-shaped protrusion 203 from damaging the outer wall of the conduit 600.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
