Description

Technical Field

[0001] The utility model relates to the technical field of catheter fixation, in particular to a catheter fixator for gastrointestinal surgery. Background Technique

[0002] When treating gastrointestinal diseases, intubation treatment is usually required after surgery to drain pus, blood, gas, fluid, etc. accumulated in the abdominal cavity and other positions. At the same time, observing and testing the discharged substances is also an important means for disease diagnosis. Due to the long indwelling time, patients often turn over frequently due to restlessness. In order to improve the patient's usage experience, the catheter located outside the body needs to be fixed to the patient's body to facilitate the patient's movement.

[0003] With the continuous development of medical standards, people pay more and more attention to physical health. In the treatment of gastrointestinal diseases, intubation treatment is an important means of medical diagnosis. Through intubation, pus, blood, gas, fluid, etc. accumulated in the abdominal cavity and other positions are drained. In the prior art, a catheter fixator is needed to fix the intubation, so as to ensure that the catheter can remain in the same position for a long time, which puts higher requirements on the stability and reliability of the catheter fixation device.

[0004] Chinese Patent No. CN214807746U discloses a catheter fixator for gastrointestinal surgery, including a bottom plate. The bottom of the bottom plate is installed with a pillar through a bolt at the top. An installation plate is sleeved outside the pillar. One side of the top of the installation plate is installed with a fixing frame through a bolt. One side inside the fixing frame is installed with a connecting frame through a bolt. The other side surface of the fixing frame is installed with a locking screw through a threaded hole. The ends of the connecting frame and the locking screw are respectively installed with clamping plates through bolts and bearings. The catheter fixator for gastrointestinal surgery of the utility model, by setting the fixing frame, clamping plate, locking screw and rubber soft pad, the staff can place the catheter in the clamping plate and manually rotate the locking screw, so that the clamping plate can fix the catheter, which is convenient for fixing catheters of different sizes, improves the practicability of the device, and the rubber soft pad can protect the catheter from damage and is convenient for the use of the catheter, and is suitable for being widely promoted and used.

[0005] However, the above device still has the following problems when in use. Although the above device achieves the effect of firm fixation and not easy to fall off, when fixing, squeezing the catheter with the clamping plate often causes the catheter to bend and block. At the same time, the above device is fixed on the edge of the bed. When the patient moves or turns over, the catheter will be pulled, which is likely to cause the catheter to fall off and even tear the wound, affecting the patient's recovery. Therefore, we propose a new catheter fixator for gastrointestinal surgery. Summary of the Utility Model

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows: A catheter fixator for gastrointestinal surgery, comprising a fixed seat, a fixed frame is fixedly connected to the top of the fixed seat, non-through chutes are symmetrically opened on both side walls of the inner cavity of the fixed frame, a fixing component is arranged in the inner cavity of the fixed frame, the fixing component includes a pressing block, a sliding block, a threaded rod and a handle, the pressing block is slidably connected to the side wall of the inner cavity of the fixed frame, sliding blocks are symmetrically and fixedly connected to both side walls of the pressing block, the sliding blocks are slidably connected to the inner cavity of the chute, a threaded rod is fixedly connected to the top of the pressing block, a handle is fixedly connected to the top of the threaded rod, the bottom of the pressing block and the top of the fixed seat are both arc-shaped, four groups of buffer fastening components are symmetrically arranged on the bottom of the pressing block and the top of the fixed seat in a uniform manner, and buckles are symmetrically and fixedly connected to the lower parts of both side walls of the fixed seat, and a ring-shaped fixing belt is fixedly connected to the two buckles.

[0008] As a further description of the above technical solution, a through threaded groove is opened at the top of the fixed frame, the threaded rod penetrates through the threaded groove until the outside, and is meshed and connected with the threaded groove through a thread groove.

[0009] As a further description of the above technical solution, non-through installation grooves are symmetrically opened in pairs on the bottom of the pressing block and the top of the fixed seat, and baffles are symmetrically and fixedly connected to the notch of the inner cavity of the installation groove.

[0010] As a further description of the above technical solution, the buffer fastening component includes a sliding block, a fastening plate, an anti-slip pad, a spring and a limiting block, the sliding block is arranged in the inner cavity of the installation groove, and the side wall of the sliding block is slidably connected to the side wall of the baffle, a plurality of springs are fixedly connected to the inner cavity of the sliding block, the other ends of the springs are fixedly connected to the side wall of the inner cavity of the installation groove, a fastening plate is fixedly connected to one side of the sliding block, and an anti-slip pad is fixedly connected to one side of the fastening plate.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. By setting up a fixed component, a buffer fastening component, etc., when it is necessary to fix the catheter, place the catheter to be fixed between the fixed seat and the four buffer fastening components on the pressing block, and then rotate the handle to drive the threaded rod to rotate. The pressing block moves downward. When the buffer fastening components at the bottom of the pressing block and the buffer fastening components on the fixed seat are both in contact with the catheter, continue to rotate the handle. At this time, the fastening plate squeezes the side wall of the catheter, and the side wall of the catheter generates a force on the fastening plate, pushing the spring to compress. At the same time, the spring generates a reaction force, which can make the fastening plate tightly press the side wall of the catheter, suitable for catheters of different models. At the same time, the anti-slip pad on the fastening plate can increase the friction with the side wall of the catheter, making the fixation more stable. Moreover, the spring can play a good buffering role on the side wall of the catheter, effectively preventing the pressing block and the fastening plate from pressing too tightly to bend and block the catheter.

[0015] 2.

[0023] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a catheter fixator for gastrointestinal surgery, including a fixed seat 1. A fixed frame 2 is fixedly connected to the top of the fixed seat 1. Non-through chutes 8 are symmetrically opened on both side walls of the inner cavity of the fixed frame 2. A fixing component 3 is arranged in the inner cavity of the fixed frame 2. The fixing component 3 includes a pressing block 3.1, a slider 3.2, a threaded rod 3.3, and a handle 3.4. The pressing block 3.1 is slidably connected to the side wall of the inner cavity of the fixed frame 2. Sliders 3.2 are symmetrically and fixedly connected to both side walls of the pressing block 3.1. The sliders 3.2 are slidably connected to the inner cavity of the chute 8. The chute 8 plays a good role in limiting and guiding the sliders 3.2. A threaded rod 3.3 is fixedly connected to the top of the pressing block 3.1. A handle 3.4 is fixedly connected to the top of the threaded rod 3.3. The bottom of the pressing block 3.1 and the top of the fixed seat 1 are both arc-shaped, so as to facilitate adapting to catheters of various sizes. Four groups of buffer fastening components 4 are evenly and symmetrically arranged at the bottom of the pressing block 3.1 and the top of the fixed seat 1. Lower parts of both side walls of the fixed seat 1 are symmetrically and fixedly connected with buckles 5. A ring-shaped fixing belt 6 is fixedly connected to the two buckles 5.

[0024] Specifically, as Figure 1As shown in the figure, a threaded groove 9 that penetrates through is opened at the top of the fixing bracket 2. The threaded rod 3.3 passes through the threaded groove 9 until the outside, and is meshed and connected with the threaded groove 9 through a threaded slot. When it is necessary to fix the catheter, place the catheter to be fixed between the fixing seat 1 and the four buffer fastening components 4 on the pressing block 3.1, and then rotate the handle 3.4 to drive the threaded rod 3.3 to rotate. The pressing block 3.1 moves downward. When the buffer fastening components 4 at the bottom of the pressing block 3.1 and the buffer fastening components 4 on the fixing seat are both in contact with the catheter, continue to rotate the handle so that the buffer fastening components 4 fasten the catheter.

[0025] Specifically, as Figure 2 shown, the fixing belt 6 includes an elastic belt 6.1, a binding belt 6.2, and a telescopic buckle 6.3. Both ends of the elastic belt 6.1 are fixedly connected to the buckle 5 respectively. The elastic belt 6.1 is connected in series with the binding belt 6.2, and a telescopic buckle 6.3 is arranged on the elastic belt 6.1. After using this device to fix the catheter, take out one end of the elastic belt 6.1 from the buckle 5, wrap the elastic belt 6.1 around the patient's body, and then fixedly connect one end of the elastic belt 6.1 to the buckle 5. At this time, the length of the elastic belt 6.1 can be increased or shortened through the telescopic buckle 6.3, so that the fixing seat 1 is fixed to the patient's body through the elastic belt 6.1, effectively preventing the catheter from being pulled when the patient moves or turns over, causing the catheter to fall off or even tear the wound. At the same time, the binding belt 6.2 is soft, light and thin, which can improve the comfort of the patient's wearing, reduce the indentation, and help improve the patient's recovery speed.

[0026] Specifically, as Figure 1 、 Figure 3 shown, non-through mounting grooves 7 are symmetrically opened in pairs at the bottom of the pressing block 3.1 and the top of the fixing seat 1. The mounting grooves 7 are arc-shaped and have the same center of the arc as the pressing block 3.1 and the fixing seat 1. Baffles 10 are symmetrically fixedly connected at the inner cavity notch of the mounting grooves 7.

[0027] Specifically, as Figure 3 shown, the buffer fastening component 4 includes a sliding block 4.1, a fastening plate 4.2, an anti-slip pad 4.3, a spring 4.4, and a limit block 4.5. The sliding block 4.1 is arranged in the inner cavity of the mounting groove 7, and the side wall of the sliding block 4.1 is slidably connected to the side wall of the baffle 10. A plurality of springs 4.4 are fixedly connected to the inner cavity of the sliding block 4.1, and the other ends of the springs 4.4 are fixedly connected to the side wall of the inner cavity of the mounting groove 7. One side of the sliding block 4.1 is fixedly connected to a fastening plate 4.2, and an anti-slip pad 4.3 is fixedly connected to one side of the fastening plate 4.2. The anti-slip pad 4.3 can increase the friction force between the catheter side wall, making the fixation more stable.

[0028] On both sides of the sliding block 4.1, limit blocks 4.5 are symmetrically and fixedly connected. The limit blocks 4.5 are arranged on one side of the inner cavity of the mounting groove 7. The baffle 10 blocks the limit blocks 4.5, so that the limit blocks 4.5 can only move in the inner cavity of the mounting groove 7, and the limit blocks 4.5 can prevent the sliding block 4.1 from being disengaged from the inner cavity of the mounting groove 7. When the four buffer fastening components 4 come into contact with the catheter side wall evenly, continue to rotate the handle 3.4. At this time, the fastening plate 4.2 presses against the catheter side wall, and the catheter side wall generates a force on the fastening plate 4.2, pushing the spring 4.4 to compress. At the same time, the spring 4.4 generates a reaction force, which can make the fastening plate 4.2 tightly press against the catheter side wall, being applicable to catheters of different models. At the same time, the anti-slip pad 4.3 on the fastening plate 4.2 can increase the friction force with the catheter side wall, making the fixation more stable. Moreover, the spring 4.4 can play a good buffering role on the catheter side wall, effectively avoiding the catheter from being bent and blocked due to the over-tight pressing of the pressing block 3.1 and the fastening plate 4.2.

[0029] It should be noted that the present utility model is a catheter fixator for gastrointestinal surgery. When it is necessary to fix a catheter, place the catheter to be fixed between the fixed seat 1 and the four buffer fastening components 4 on the pressing block 3.1, and then rotate the handle 3.4 to drive the threaded rod 3.3 to rotate. The pressing block 3.1 moves downward. When the buffer fastening components 4 at the bottom of the pressing block 3.1 and the buffer fastening components 4 on the fixed seat both come into contact with the catheter, continue to rotate the handle. At this time, the fastening plate 4.2 presses against the catheter side wall, and the catheter side wall generates a force on the fastening plate 4.2, pushing the spring 4.4 to compress. At the same time, the spring 4.4 generates a reaction force, which can make the fastening plate 4.2 tightly press against the catheter side wall, being applicable to catheters of different models. At the same time, the anti-slip pad 4.3 on the fastening plate 4.2 can increase the friction force with the catheter side wall, making the fixation more stable. Moreover, the spring 4.4 can play a good buffering role on the catheter side wall, effectively avoiding the catheter from being bent and blocked due to the over-tight pressing of the pressing block 3.1 and the fastening plate 4.2.

[0030] After the catheter is fixed, take out one end of the elastic band 6.1 from the buckle 5, wrap the elastic band 6.1 around the patient's body, and then fixedly connect one end of the elastic band 6.1 to the buckle 5. At this time, the length of the elastic band 6.1 can be increased or shortened through the telescopic buckle 6.3, so as to fix the fixed seat 1 to the patient's body through the elastic band 6.1, effectively preventing the catheter from being pulled and causing the catheter to fall off or even tear the wound when the patient moves or turns over. At the same time, the binding band 6.2 is soft and light, which can improve the comfort of the patient's wearing, reduce the indentation, and contribute to improving the patient's recovery speed.
