Description

Technical Field

[0001] This utility model relates to the field of catheter fixation technology, and in particular to a catheter fixation device. Background Technology

[0002] Anesthesia catheter fixation devices refer to medical devices used to fix catheters used during anesthesia, such as endotracheal tubes and central venous catheters, to ensure the stability and safety of the catheters during anesthesia. These devices may include various types, such as strap fixators, clip fixators, and adhesive fixators, and the specific type may vary depending on the manufacturer and the actual application scenario.

[0003] Currently, existing catheter fixation devices lack sufficient flexibility and adaptability, making it difficult to meet the needs of catheters of different sizes. This can easily lead to catheter slippage or dislodgement during use, which not only increases the risk to patients but also reduces the efficiency and reliability of medical care. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot flexibly adapt to and securely clamp catheters of different sizes, which can easily lead to the catheters slipping or falling off during use. Therefore, this invention proposes a catheter fixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A catheter fixation device, comprising:

[0007] A patch, wherein a hole is formed at the center of the top of the patch, and a fixing seat is fixedly installed on the outer ring of the hole at the top of the patch. A through hole communicating with the hole is formed at the center of the fixing seat, and the fixing seat is T-shaped.

[0008] Fixation components are mounted on the patch and used to fix the device to fit different patient body shapes;

[0009] The clamping mechanism is mounted on the fixed base and is used to clamp and fix the conduit.

[0010] In one possible design, the fastening assembly includes a main strap fixedly disposed on one side of the patch, one end of the main strap being fixedly disposed with a threading loop, and a secondary strap fixedly disposed on the other side of the patch, the top of the secondary strap being sewn with a Velcro loop and the bottom of the secondary strap being sewn with a Velcro hook.

[0011] In one possible design, the clamping mechanism includes multiple clamping frames that are slidably arranged in a ring through the inner wall of the through hole of the fixed base. Each clamping frame has a trapezoidal block fixedly arranged on its rear side. Each trapezoidal block is slidably arranged inside the fixed base. The inner wall of the through hole of the fixed base has multiple springs, the same number as the clamping frames, embedded in it. The other end of each spring is fixedly connected to a corresponding clamping frame. A conical top frame is slidably arranged on the outer ring of the bottom of the fixed base. The bottom of the fixed base has a slot adapted to the conical top frame above it. The trapezoidal blocks fit against the inclined side of the conical top frame.

[0012] In one possible design, multiple anti-slip strips are fixedly provided on the side of the multiple clamping frames that are close to each other.

[0013] In one possible design, the bottom of the patch is fixedly provided with multiple annular silicone strips, and the bottom of each of the silicone strips is provided with anti-slip protrusions.

[0014] In one possible design, the patch, main strap, and secondary strap all have multiple evenly distributed ventilation holes at their tops.

[0015] In this application, before starting use, the patient's skin at the catheter insertion site is cleaned to ensure that there are no oils, sweats, or other substances on the skin surface. Then, the conical top frame is gently pushed to slide along the slot of the fixation base, so that the trapezoidal block and the inclined side of the conical top frame are in contact and move against each other, pushing multiple clamps to move backward and retract into the fixation base. While the clamps are moving, they also exert force on the springs, causing the springs to be compressed. When all the clamps are in the open state and are tightly against the inner wall of the hole, the hole of the patch and the through hole on the fixation base are fitted over the outside of the catheter, and the catheter is positioned between the clamps. Then, the part of the patch with the annular silicone strip at the bottom is attached to the skin, ensuring that it fits tightly against the skin.

[0016] Next, wrap the main strap around the patient's body from one side of the patch, ensuring that the insertion loop is in the proper position. Then wrap the secondary strap around the other side of the patch and attach the hook and loop sides of the Velcro to ensure that the main strap and secondary strap fit tightly. At the same time, adjust the tightness to fit the patient's body shape and prevent discomfort.

[0017] Then gently push the conical top bracket downwards. The conical top bracket slowly detaches from the slot. At this time, the trapezoidal block that was in contact with the conical top bracket disengages, and the compressed spring pushes the clamping bracket forward toward the conduit through its own elasticity. When multiple clamping brackets approach the conduit, the side with the anti-slip strip abuts against the conduit, thereby clamping and fixing the conduit. Then gently pull the conduit to ensure that the conduit is firmly clamped between the clamping brackets and will not slip or fall off.

[0018] This utility model has the following beneficial effects:

[0019] This invention achieves flexible adaptation to and stable binding to the patient's body shape through the setting of the fixing components, effectively improving the stability of catheter fixation and the comfort of patient use.

[0020] This utility model, through the setting of the clamping mechanism, utilizes the cooperation of trapezoidal blocks, springs and conical top frames to achieve efficient and stable clamping of catheters of different specifications, which not only ensures the firmness of the catheters during use, but also facilitates medical staff to make quick adjustments according to actual needs, greatly improving the convenience of medical operations and the comfort of patients.

[0021] This invention, through the design of a clamping mechanism, achieves flexible adaptation and stable clamping of catheters of different sizes, effectively preventing the catheters from slipping or falling off during use, thereby improving the safety and reliability of medical care.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Reference Figure 1-4 A fixing device, comprising:

[0030] The device consists of three parts: patch 1, fixing component and clamping mechanism. Patch 1 is the main part of the device. A hole 101 is opened at the center of its top to accommodate or guide the conduit. A T-shaped fixing seat 4 is fixedly installed around the outer ring of the hole 101 on the top of patch 1. A through hole connected to the hole 101 is opened at the center of the fixing seat 4 for the conduit to pass through.

[0031] The fixation component is set on the patch 1 to fix the device to different patient body shapes. The fixation component includes a main strap 2 fixed on one side of the patch 1 and a secondary strap 3 fixed on the other side of the patch 1. One end of the main strap 2 is fixed with a loop 11 to facilitate adjustment of the tightness of the strap. The top of the secondary strap 3 is sewn with a Velcro loop 12 and the bottom is sewn with a Velcro hook 13. Through the adhesive action of the Velcro, the main strap 2 and the secondary strap 3 can be tightly attached together, thereby fixing the device to the patient's body.

[0032] In addition, to increase the breathability and comfort of the device, multiple evenly distributed ventilation holes 10 are provided on the top of the patch 1, the main strap 2 and the secondary strap 3.

[0033] A clamping mechanism is mounted on the fixed base 4 to clamp and fix conduits of different sizes. The clamping mechanism includes multiple clamping frames 5 arranged in a ring shape and slidingly disposed within the inner wall of the through hole of the fixed base 4. Each clamping frame 5 has a trapezoidal block 6 fixedly mounted on its rear side. These trapezoidal blocks 6 are slidably disposed inside the fixed base 4. Multiple springs 7, the same number as the clamping frames 5, are also embedded in the inner wall of the through hole of the fixed base 4. The other end of each spring 7 is fixedly connected to a corresponding clamping frame 5, providing a forward thrust to the clamping frame 5. When clamping the conduit, the conical top bracket 9 at the bottom of the fixing base 4 can be pushed up or down. The conical top bracket 9 is slidably installed on the outer periphery of the bottom of the fixing base 4 and can be disengaged from the slot. Its inclined side is in contact with the inclined side of the trapezoidal block 6. When the conical top bracket 9 is pushed upward, it slides along the slot and pushes the trapezoidal block 6 into the interior of the fixing base 4. Since the trapezoidal block 6 is fixedly connected to the clamping frame 5, the clamping frame 5 will also move backward and retract into the fixing base 4. At this time, the spring 7 will be compressed and store elastic potential energy. When the conical top bracket 9 is pushed downward and completely disengaged from the trapezoidal block 6, the spring 7 will release its stored elastic potential energy, pushing the clamping frame 5 forward and closer to the conduit. At this time, the anti-slip strip 8 on the clamping frame 5 will abut against the conduit, thereby achieving clamping and fixing of the conduit.

[0034] This application can be used in the field of catheter fixation devices for anesthesiology, or in other fields applicable to this application.

[0035] Example 2

[0036] Based on Embodiment 1, Embodiment 2 further includes: a catheter fixation device, which is applied to the field of catheter fixation device technology in anesthesiology. In order to increase the comfort between the patch 1 and the skin, multiple annular silicone strips 14 are fixedly installed at the bottom of the patch 1. At the same time, in order to increase the friction between the patch 1 and the skin and improve the stability of the device, multiple anti-slip protrusions are evenly arranged at the bottom of the silicone strips 14.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
