Description

Technical Field

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

[0002] In clinical interventional transfusion therapy, the transfusion catheter is the core instrument for blood transfusion and interventional procedures. To ensure smooth transfusion and stable operation, the catheter needs to be positioned and fixed by a special fixation device. Existing fixation devices are mostly based on the structure of film, buckle, and strap, and are equipped with fixation wings and limiting components to achieve the connection and fixation of the catheter to the human skin. They are commonly used supporting instruments in clinical interventional departments and intensive care units.

[0003] Existing catheter fixation devices for transfusion intervention have relatively simple fixation structures, mostly only able to achieve simple limitation of the catheter body, and cannot specifically fix the wing-shaped structure and docking point of the catheter. This easily leads to problems such as catheter displacement and loosening of the docking point. In addition, some devices rely on sutures or strong film to achieve fixation, which is cumbersome and easily causes skin damage. At the same time, the limiting components lack anti-dislodgement structures, and are prone to loosening when pulled by external forces. They are difficult to meet the requirements of stability and ease of operation for catheter fixation in clinical transfusion intervention procedures.

[0004] Based on this, a fixation device for blood transfusion interventional catheters is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a fixation device for a blood transfusion interventional catheter in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixation device for a blood transfusion interventional catheter includes a fixation base, straps, and Velcro. A wing seat is fixedly connected to the top of the fixation base. A deflection shaft is fixedly connected to one side of the top of the fixation base. A pressure plate is rotatably connected to the outer side of the deflection shaft. Through holes are provided on both sides of the fixation base, and a limiting rod is inserted into the through holes. Fan plates are rotatably connected to both sides of the fixation base via torsion springs. A connecting strip is fixedly connected to the outer side of the fixation base. A semi-enclosed buckle is fixedly connected to one end of the connecting strip. A limiting groove is provided on the inner side of the semi-enclosed buckle. A rotating component is rotatably connected inside the limiting groove. A rotating tooth is fixedly connected to the outer side of the rotating component. Straps are fixedly connected to both ends of the fixation base, and Velcro is fixedly connected to the straps.

[0008] Preferably, the pressure plate is rotatably connected to the fixed base via a deflection shaft, and one end of the pressure plate abuts against the outer side of the limiting rod.

[0009] Preferably, the fan plate is rotatably connected to the fixed base via a torsion spring, and one side of the fan plate abuts against one end of the limiting rod.

[0010] Preferably, the semi-enclosed buckle and the rotating component are provided with a locking slot for the conduit to be engaged, and the rotating component is rotatably connected to the semi-enclosed buckle through a limiting groove.

[0011] Preferably, the rotating teeth are equidistantly distributed on the outer side of the rotating component, and one side of the rotating teeth is in contact with one side of the semi-enclosed buckle.

[0012] Preferably, the straps are distributed at both ends of the fixing base, and the straps are detachably connected by Velcro.

[0013] Preferably, the wing seat has a groove inside that matches the wing-shaped portion of the conduit, and the top of the wing seat fits into the bottom of the pressure plate.

[0014] Preferably, the outer side of the limiting rod is in contact with the inner wall of the through hole, and the limiting rod is disposed inside the through hole.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This utility model provides a technical solution:

[0025] A fixation device for a blood transfusion interventional catheter includes a fixation base 1, a strap 2, and Velcro 3. A wing seat 10 is fixedly connected to the top of the fixation base 1. A deflection shaft 7 is fixedly connected to one side of the top of the fixation base 1. A pressure plate 4 is rotatably connected to the outer side of the deflection shaft 7. Through holes 11 are provided on both sides of the fixation base 1. A limit rod 8 is inserted into the inside of the through holes 11. A fan plate 9 is rotatably connected to both sides of the fixation base 1 via a torsion spring. A connecting strip 5 is fixedly connected to the outer side of the fixation base 1. A semi-enclosed buckle 6 is fixedly connected to one end of the connecting strip 5. A limit groove 14 is provided on the inner side of the semi-enclosed buckle 6. A rotating component 12 is rotatably connected inside the limit groove 14. A rotating tooth 13 is fixedly connected to the outer side of the rotating component 12. Straps 2 are fixedly connected to both ends of the fixation base 1. Velcro 3 is fixedly connected to the straps 2.

[0026] The connecting strip 5 is designed to facilitate the installation of the conduit, and the connecting strip 5 is made of flexible material.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the pressure plate 4 is rotatably connected to the fixed base 1 through the deflection shaft 7. One end of the pressure plate 4 abuts against the outer side of the limiting rod 8. The pressure plate 4 can rotate around the deflection shaft 7. The limiting rod 8 limits the position of the pressure plate 4 after rotation, thereby realizing the opening and closing of the pressure plate 4.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the fan plate 9 is rotatably connected to the fixed base 1 via a torsion spring. One side of the fan plate 9 abuts against one end of the limiting rod 8. With the help of the elastic force of the torsion spring, the fan plate 9 naturally fits against the end of the through hole 11, axially limiting the inserted limiting rod 8 and preventing the limiting rod 8 from coming out of the through hole 11. External force can rotate the fan plate 9 to open it, facilitating the insertion and removal of the limiting rod 8.

[0029] Specifically, such as Figure 3 As shown, the semi-enclosed buckle 6 and the rotating part 12 are provided with a slot for the conduit to be engaged. The rotating part 12 is rotatably connected to the semi-enclosed buckle 6 through the limiting groove 14. The rotating part 12 can rotate around its own axis in the limiting groove 14 to realize the overlap and misalignment of the slots on the semi-enclosed buckle 6 and the rotating part 12, thereby completing the insertion and clamping of the conduit.

[0030] Specifically, such as Figure 3 As shown, the rotating teeth 13 are evenly distributed on the outer side of the rotating part 12. One side of the rotating teeth 13 is in contact with one side of the semi-enclosed buckle 6. The rotating teeth 13 increase the hand friction when the rotating part 12 rotates, making it easier for the operator to apply force to rotate the rotating part 12. At the same time, the contact between the teeth and the semi-enclosed buckle 6 forms a slight positioning, preventing the rotating part 12 from rotating randomly.

[0031] Specifically, such as Figure 1 As shown, the straps 2 are distributed at both ends of the fixing base 1. The straps 2 are detachably connected by Velcro 3. By pulling the straps 2 at both ends around the human body tube fixing part, the fixing base 1 is fixed on the human skin by using the hook and loop fastener of Velcro 3. The Velcro 3 can be adjusted to fit different human body parts.

[0032] Specifically, such as Figure 2 As shown, the inside of the wing seat 10 is provided with a groove that matches the wing-shaped part of the guide tube. The top of the wing seat 10 fits against the bottom of the pressure plate 4. The groove fits and positions the wing-shaped structure of the guide tube to prevent the guide tube from being displaced radially and axially on the fixed seat 1. After the pressure plate 4 is pressed, it forms a pressing limit on the wing-shaped part, improving the positioning stability.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the outer side of the limiting rod 8 fits against the inner wall of the through hole 11. The limiting rod 8 is set inside the through hole 11, and the through hole 11 provides a guide for the insertion of the limiting rod 8. The mating surfaces prevent the limiting rod 8 from shaking inside the hole, thus ensuring the limiting effect on the pressure plate 4.

[0034] In summary, the blood transfusion intervention catheter fixing device provided in this embodiment first fits the wing-shaped part of the blood transfusion intervention catheter into the slot of the wing seat 10, then attaches the catheter body to the corresponding position of the fixing seat 1, then rotates the pressure plate 4 around the deflection axis 7 to press the pressure plate 4 against the top of the catheter and the wing seat 10, then inserts the limiting rod 8 into the through hole 11 so that the limiting rod 8 abuts against the end of the pressure plate 4. At this time, the fan plate 9 under the action of the torsion spring attaches to the end of the limiting rod 8 to complete the limiting.

[0035] Next, insert the connecting part of the conduit into the latch of the semi-enclosed buckle 6, rotate the rotating tooth 13 to drive the rotating part 12 to rotate in the limiting groove 14, so that the latch of the rotating part 12 is misaligned with the latch of the semi-enclosed buckle 6, thus completing the clamping and limiting of the connecting part of the conduit.

[0036] Finally, pull the straps 2 at both ends of the fixing base 1, wrap the straps 2 around the fixed part of the human body, and fix them with Velcro 3 to complete the installation and fixation of the entire device; when disassembling, first turn the fan plate 9 to open, pull out the limit rod 8, rotate around the deflection shaft 7 to open the pressure plate 4, then rotate the rotating tooth 13 in the opposite direction to make the rotating part 12 coincide with the buckle 6, take out the tube, and finally tear off the Velcro 3 to untie the straps 2.

[0037] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
