Description

Technical Field

[0001] The present application relates to the technical field of medical appliances, and in particular to a drainage puncture fixation device. Background Art

[0002] Through medical examination, when it is found that the patient has pleural effusion, the fluid can be extracted through thoracentesis, so as to conduct various examinations and find the cause of the disease. If there is a lot of pleural effusion, the effusion will compress the lungs, or if the pleural effusion lasts too long, the fibrin in it will easily become organized and the two layers of pleura will adhere, thus affecting the respiratory function of the lungs. At this time, the effusion needs to be drained through thoracentesis.

[0003] Thoracentesis and drainage is one of the important techniques for the treatment of pleural effusion. It mainly involves piercing the skin, intercostal tissue, and parietal pleura through a puncture needle to enter the pleural cavity, and drain the effusion in the pleural cavity to the outside of the body, thereby alleviating the patient's chest tightness, dyspnea and other symptoms. Thoracentesis and drainage can use two-dimensional B-ultrasound positioning markers to roughly determine the puncture site, and the doctor punctures and drains according to the positioning markers or approximate position.

[0004] In general, in the treatment of pleural effusion, a long-term indwelling drainage tube is often required to drain the pleural effusion and ascites, and to inject chemotherapy or targeted drugs into the pleural cavity and abdomen through the drainage tube for treatment. However, after the indwelling drainage tube in the thoracic cavity, the external drainage tube is easily shaken by external forces, causing the puncture drainage tube to be slightly pulled out and causing damage to the patient's wound, affecting the safety of the device. Summary of the invention

[0005] The purpose of the present application is to solve the problem that after a drainage tube is placed in the chest cavity, the external drainage tube is easily shaken by external force, causing the puncture drainage tube to be slightly pulled out and causing damage to the patient's wound. The present application provides a drainage puncture fixation device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A drainage puncture fixing device comprises an elastic chest strap, one end of the elastic chest strap is provided with an adjusting port, a positioning strap is installed inside the adjusting port, one end of the positioning strap is provided with a positioning hole, a mounting ring is fixedly connected inside the positioning hole, an arched corrugated tube is inserted inside the mounting ring, and a clamping assembly for fixing the arched corrugated tube is installed inside the mounting ring, one end of the elastic chest strap is fixedly connected to a U-shaped adjusting plate, an adjusting slider is symmetrically and slidably connected inside the U-shaped adjusting plate, an adjusting rod is fixedly connected to the top of the adjusting slider, one end of the U-shaped adjusting plate is symmetrically fixedly connected to the positioning rod, one end of the adjusting slider is fixedly connected to a push block, and an adjusting assembly for fixing the adjusting slider is installed inside the U-shaped adjusting plate.

[0008] By adopting the above technical scheme and setting up the coordinated use of the fixing component and the adjusting component, when the drainage tube passes through the arched bellows and the mounting ring and is inserted into the patient's body, the arched bellows and the positioning belt are fixed by pulling one end of the arched bellows into the interior of the mounting ring, so that the arched bellows protects the end of the drainage tube extending out of the patient's body. At the same time, the external end of the drainage tube extending from one end of the arched bellows is stored by guiding it through between the two positioning rods and bypassing one end of the adjusting rod, and by pushing the push block to cooperate with the adjusting component, thereby effectively reducing the shaking of the external end of the drainage tube caused by external force and improving the safety of the device.

[0009] Furthermore, the fixing component includes an annular groove opened inside the mounting ring, a socket is symmetrically opened on the top of the annular groove, an insert ring is inserted inside the mounting ring, one end of the insert ring is symmetrically fixedly connected with a hollow storage block adapted to the socket, an ejection spring is fixedly connected inside the hollow storage block, a fixed clamping block is fixedly connected to the top of the ejection spring, one end of the fixed clamping block is slidably connected to the inside of the hollow storage block, and a clamping groove adapted to the fixed clamping block is symmetrically opened on the top of the annular groove.

[0010] By adopting the above technical scheme, by setting the coordinated use of the ejection spring and the fixed card block, when the traction plug ring drives the hollow storage block to pass through the socket and insert into the interior of the ring groove, the hollow storage block is adjusted to align with the card slot by rotating the plug ring, so that the ejection spring rebounds and pushes one end of the fixed card block to be clamped into the interior of the card slot, thereby facilitating the clamping and fixing between one end of the arched corrugated tube and the mounting ring, so that the arched corrugated tube forms a protection for the drainage tube at one end extending through the mounting ring and out of the patient's body, thereby improving the safety of the device.

[0011] Furthermore, the outer periphery of the insert ring is provided with friction patterns.

[0012] By adopting the above technical solution, the friction force on the surface of the insert ring is effectively improved by setting the friction pattern, thereby improving the practicability of the device.

[0013] Furthermore, the adjustment component includes an elastic ratchet gear symmetrically fixedly connected to the inside of the U-shaped adjustment plate, and one end of the adjustment slider is symmetrically fixedly connected to an adjustment block adapted to the elastic ratchet gear.

[0014] By adopting the above technical scheme, by setting the coordinated use of the elastic ratchet gear and the adjusting card block, when the adjusting slider and the adjusting card block are mobilized by pushing the push block to move along the length direction of the U-shaped adjusting plate, the adjusting card block pushes the elastic ratchet gear to produce a contraction deformation and release the obstruction of the adjusting card block. Then, when the adjusting slider is pushed to drive the adjusting rod to move to the appropriate position, the elastic ratchet gear produces a rebound deformation and forms a resistance to the two ends of the adjusting card block, thereby facilitating the rapid positioning of the adjusting slider and the adjusting rod, and conveniently completing the storage of the external end of the drainage tube extending through the arched corrugated tube, thereby further improving the safety of the device.

[0015] Furthermore, the tops of the adjusting rod and the positioning rod are both fixedly connected with cover plates.

[0016] By adopting the above technical solution, the cover plate is provided to facilitate positioning of the drainage tube passing through the adjusting rod and the positioning rod, which effectively reduces the possibility that the external end of the drainage tube is separated from the adjusting rod and the positioning rod, thereby improving the safety of the device.

[0017] Furthermore, one end of the adjusting rod and the positioning rod is sleeved with a sleeve rod.

[0018] By adopting the above technical solution, by setting the sleeve rod and the adjustment rod and the positioning rod for use in coordination, the friction between the drainage tube and the adjustment rod and the positioning rod is effectively reduced, and the smoothness of the adjustment slider moving along the direction of the U-shaped adjustment plate is improved.

[0019] Furthermore, one end of the positioning belt is symmetrically fixedly connected with a Velcro velvet surface, and the inside of the adjustment port is symmetrically fixedly connected with a Velcro hook surface adapted to the Velcro velvet surface.

[0020] By adopting the above technical solution, by setting the coordination of the Velcro velvet surface and the Velcro hook surface, it is convenient to adjust the installation area of ​​the positioning belt inside the adjustment port according to the patient's puncture area, thereby improving the application range of the device.

[0021] Furthermore, one end of the elastic chest strap is fixedly connected with a hook.

[0022] By adopting the above technical solution, a hook is provided to facilitate hanging the drainage bag on one end of the elastic chest belt, thereby reducing the weight of the drainage tube and improving the practicability of the device.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application sets up a fixing component and an adjusting component for use together, so that when the drainage tube passes through the arched bellows and the mounting ring and is inserted into the patient's body, the arched bellows and the positioning belt are fixed by pulling one end of the arched bellows into the interior of the mounting ring, so that the arched bellows protects the end of the drainage tube extending out of the patient's body, and at the same time guides it through between the two positioning rods and bypasses one end of the adjusting rod, and the external end of the drainage tube extending from one end of the arched bellows is stored by pushing the push block to cooperate with the adjusting component, thereby effectively reducing the shaking of the external end of the drainage tube caused by external force and improving the safety of the device.

[0025] 2. The present application sets up an ejection spring and a fixed card block for use together, so that when the traction plug ring drives the hollow receiving block to pass through the socket and insert into the interior of the ring groove, the hollow receiving block is adjusted to align with the card slot by rotating the plug ring, so that the ejection spring rebounds and pushes one end of the fixed card block to be clamped into the interior of the card slot, thereby facilitating the clamping and fixing between one end of the arched bellows and the mounting ring, so that the arched bellows forms a protection for the drainage tube at one end extending through the mounting ring and out of the patient's body, thereby improving the safety of the device.

[0026] 3.

[0037] The outer periphery of the insert ring 13 is provided with friction lines 18;

[0038] The adjustment assembly includes an elastic ratchet gear 19 symmetrically fixedly connected to the inside of the U-shaped adjustment plate 7, and one end of the adjustment slider 8 is symmetrically fixedly connected to an adjustment block 20 adapted to the elastic ratchet gear 19;

[0039] The tops of the adjusting rod 9 and the positioning rod 10 are fixedly connected with a cover plate 22;

[0040] One end of the positioning belt 3 is symmetrically fixedly connected with a Velcro velvet surface 24 , and the inside of the adjustment port 2 is symmetrically fixedly connected with a Velcro hook surface 25 adapted to the Velcro velvet surface 24 .

[0041] When in use, firstly, the elastic chest strap 1 is tied outside the patient's body, and the puncture area of ​​the two-dimensional B-ultrasound positioning mark is set inside the adjustment port 2, and then the positioning strap 3 is manually pulled to drive the positioning hole 4 to coincide with the puncture area of ​​the two-dimensional B-ultrasound positioning mark, and the Velcro velvet surface 24 is pressed to make the Velcro velvet surface 24 adhere to the Velcro hook surface 25 at the corresponding position, so as to complete the fixation of the positioning strap 3 and the positioning hole 4, and then one end of the drainage tube is manually pulled around one end of the adjustment rod 9 and installed between the two positioning rods 10, and at the same time, one end of the drainage tube is resisted by the cover plate 22, so as to be installed between the cover plate 22 and the U-shaped adjustment plate 7;

[0042] Then, one end of the drainage tube is manually pulled through the arched bellows 6, and inserted into the area in the patient's body that needs drainage through the mounting ring 5. Then, one end of the hollow receiving block 14 is driven through the socket 12 by manually pulling the insert ring 13, and inserted into the inside of the annular groove 11. Then, the hollow receiving block 14 is driven to move along the inner wall of the annular groove 11 by pulling the insert ring 13, so that the fixed block 16 is squeezed by the top of the annular groove 11 and moves toward the length of the hollow receiving block 14, and the fixed block 16 squeezes the ejection spring. 15 produces contraction deformation, and at the same time, the hollow receiving block 14 drives the fixed card block 16 to move to the bottom of the card slot 17.

[0043] Then, the push block 21 is manually pushed to drive the adjusting slider 8 to move away from the positioning rod 10 along the length direction of the U-shaped adjusting plate 7, and at the same time, the adjusting slider 8 drives the adjusting rod 9 to push one end of the drainage tube to move away from the positioning rod 10, and the adjusting slider 8 drives the adjusting block 20 to push one end of the elastic ratchet gear 19 to produce a contraction deformation. When the adjusting slider 8 drives the adjusting block 20 to move to a suitable position, one end of the elastic ratchet gear 19 produces a rebound deformation and clamps one end of the adjusting block 20, so that the adjusting rod 9 is clamped and fixed inside the U-shaped adjusting plate 7, thereby realizing the positioning and storage of one end of the drainage tube extending through the arched corrugated tube 6, reducing the shaking of the external end of the drainage tube, and further improving the safety of the device.

[0044] Reference Figure 1 and Figure 4One end of the adjusting rod 9 and the positioning rod 10 are both sleeved with a sleeve rod 23.

[0045] When in use, by setting the sleeve rod 23, when one end of the drainage tube passes through one end of the positioning rod 10 and the adjusting rod 9, a rolling friction is formed between the sleeve rod 23 and the positioning rod 10 and the adjusting rod 9, thereby effectively reducing the friction between the drainage tube and the adjusting rod 9 and the positioning rod 10, thereby improving the practicability of the device.

[0046] Reference Figure 1 and Figure 2 One end of the elastic chest strap 1 is fixedly connected with a hook 26.

[0047] When in use, the drainage bag connected to one end of the drainage tube is hung on the hook 26, so that the elastic chest strap 1 bears the weight of the drainage bag, reducing the weight of the drainage tube on the drainage bag, thereby reducing the displacement of the drainage tube caused by the weight of the drainage bag, and further improving the safety of the device.

[0048] Working principle: first, the elastic chest strap 1 is tied outside the patient's body, and the puncture area of ​​the two-dimensional B-ultrasound positioning mark is set inside the adjustment port 2, and then the positioning strap 3 is manually pulled to drive the positioning hole 4 to coincide with the puncture area of ​​the two-dimensional B-ultrasound positioning mark, and the Velcro velvet surface 24 is pressed to make the Velcro velvet surface 24 adhere to the Velcro hook surface 25 at the corresponding position;

[0049] Then, one end of the drainage tube is manually pulled through the arched bellows 6, and inserted into the area in the patient's body that needs drainage through the mounting ring 5, and then one end of the hollow receiving block 14 is driven to pass through the socket 12 and inserted into the inside of the annular groove 11 by manually pulling the insert ring 13, and then the hollow receiving block 14 is driven to move along the inner wall of the annular groove 11 by pulling the insert ring 13, so that the fixed block 16 is squeezed by the top of the annular groove 11 and moves toward the length of the hollow receiving block 14, and the fixed block 16 squeezes the ejection spring 15 to produce a contraction deformation, and at the same time, the hollow receiving block 14 drives the fixed block 16 to move to the bottom of the slot 17, at this time, the ejection spring 15 is relieved of force and produces a rebound deformation, and at the same time, the ejection spring 15 ejects one end of the fixed block 16 and is stuck in the inside of the slot 17, so that the arched bellows 6 forms a fixed protection for the external end of the drainage tube;

[0050] Then, one end of the drainage tube is manually pulled around one end of the adjusting rod 9 and installed between the two positioning rods 10, and at the same time, one end of the drainage tube is resisted by the cover plate 22, so that it is installed between the cover plate 22 and the U-shaped adjusting plate 7, and then the push block 21 is manually pushed to drive the adjusting slider 8 to move away from the positioning rod 10 along the length direction of the U-shaped adjusting plate 7, and at the same time, the adjusting slider 8 drives the adjusting rod 9 to push one end of the drainage tube to move away from the positioning rod 10, and the adjusting slider 8 drives the adjusting block 20 to push one end of the elastic ratchet gear 19 to produce a contraction deformation. When the adjusting slider 8 drives the adjusting block 20 to move to a suitable position, one end of the elastic ratchet gear 19 produces a rebound deformation and clamps one end of the adjusting block 20, so that the adjusting rod 9 is clamped and fixed inside the U-shaped adjusting plate 7, thereby realizing the positioning and storage of one end of the drainage tube extending through the arched corrugated tube 6.
