Description
Technical Field
[0001] This utility model belongs to the field of medical technology, specifically a venous puncture hemostasis suture device. Background Technology
[0002] Venipuncture is a common medical procedure that involves inserting a needle or catheter through the skin to directly access the patient's venous system. Deep vein puncture, in particular, involves puncturing a deep vein through the skin and inserting various catheters into the lumen of a large blood vessel or the heart chamber. This technique is primarily used to measure various physiological parameters, providing a direct and convenient method for various treatments, and is especially important in the intensive care unit when rescuing critically ill patients. Because the punctured vein is located deep within the patient's body, a large skin incision is required to connect the catheter. Therefore, proper suturing and hemostasis of the incision after the puncture procedure are crucial for postoperative wound healing and infection prevention.
[0003] After existing intravenous puncture and suturing procedures, the sutures need to be tightened to prevent blood leakage due to the deep wound. After the wound heals, it often leaves wrinkled scars. The skin that has been squeezed and tightened may also have mismatched gaps, which can lead to wound damage and infection risks.
[0004] Therefore, it is necessary to develop a venous puncture hemostasis suture device that can provide pressure for hemostasis while protecting the wound skin. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this invention is to provide a venous puncture hemostasis suture device that uses a three-way tubular structure to tighten the suture and apply vertical pressure to the wound to stop bleeding, flatten skin folds, thereby promoting wound healing, protecting the integrity and smoothness of the skin at the wound site, and preventing skin infection.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A venous puncture hemostasis suture device includes a main tube, a pressure plate fixedly connected to the bottom end of the main tube, a wire inlet on the pressure plate, the wire inlet communicating with the main tube, a side tube fixedly connected to the side wall of the main tube, a threaded outer circumference of the side tube, a side cover fitted to the end of the side tube away from the main tube, the inner wall of the side cover threadedly engaging with the outer circumference of the side tube, a sliding column extending into the side tube fixedly connected inside the side cover, a rotating column rotatably connected to the end of the sliding column near the main tube, a pushing plate rotatably connected to the end of the rotating column away from the sliding column, both the sliding column and the pushing plate slidingly engaging with the inner wall of the side tube, an arc-shaped blade parallel to the inner wall of the main tube fixedly connected to the upper part of the pushing plate, and a resistance hemisphere parallel to the inner wall of the main tube fixedly connected to the upper part of the pushing plate.
[0007] The basic principle is as follows: when the suture is finished, the two sutures at the beginning and end are twisted together, passed through the guide tube opening and the main tube, and the wound is tightened. The side cover is rotated to push the resistance hemisphere on the push plate to lock the suture. At the same time, the curved blade is pushed to cut the suture above the resistance hemisphere. The suture is kept tight and fixed in the main tube until the wound heals and the suture is removed together.
[0008] The beneficial effects of the basic solution are: 1. By tightening the sutures through the main tube and locking the resistance hemisphere, the reaction force of the suture pulling can pull the entire main tube and the pressure plate to generate vertical pressure on the wound, promote hemostasis and healing of the wound, and protect the skin to restore its smoothness.
[0009] 2. By simultaneously pushing the curved blade and the resistance hemisphere to cut the upper suture, medical staff do not need to use scissors to cut the suture again, reducing suturing steps and speeding up the operation.
[0010] 3. The design of tightening the sutures by the main tube and locking the hemispherical resistance can tighten the sutures, ensuring the wound healing rate and preventing the wound from opening and becoming infected.
[0011] Furthermore, the outer wall of the top of the main pipe is threaded, and a top cover is fitted onto the top of the main pipe, with the inner wall of the top cover threadedly engaging with the outer wall of the top of the main pipe.
[0012] The benefits of the basic solution are: by attaching the top cover to the top of the tube, a clean and sterile environment is ensured inside the tube; the entire suture device can be disassembled and used immediately, preventing contamination inside the tube and infection of the patient's wound.
[0013] Furthermore, the top wall of the side cover has several vent holes corresponding to the side tubes.
[0014] The beneficial effects of the basic design are: the air holes opened in the top wall of the side cover can prevent the formation of a sealed cavity between the gaps inside the side cover and the side tube, enhance the smoothness of the side cover rotation, and reduce the occurrence of accidents during the sewing process.
[0015] Furthermore, the bottom wall of the pressure plate has several wire grooves that extend radially outward from the wire inlet to the outer periphery of the pressure plate.
[0016] The beneficial effects of the basic approach are: by pressing the radial guide grooves on the bottom wall of the disc, the suture device can store the taut sutures in the guide grooves, enhancing the fit of the bottom wall of the disc to the wound skin, thereby better applying pressure to the wound for hemostasis.
[0017] Furthermore, several air passages are opened on the pressure plate between the wire grooves.
[0018] The beneficial effect of the basic solution is that the air permeability of the compression plate is enhanced by the air vents on the compression plate, thus preventing anaerobic bacterial infection in the deep wounds that are being compressed.
[0019] Furthermore, the pressure plate has an annular medicine groove, and the medicine groove is lined with a breathable fiber ring sheet.
[0020] The beneficial effects of the basic solution are: by adding hemostatic, antibacterial and healing-promoting drugs to the breathable fiber ring in the medicine tank, these drugs can enter the wound through the air vents to promote hemostasis and healing. In addition, the breathable fiber ring can also isolate the inside and outside of the air vents, preventing external pathogens from entering the wound through the air vents while allowing air to pass through.
[0021] Furthermore, the top wall of the pressure plate has symmetrical locking grooves, and the bottom side wall of the main pipe has locking holes corresponding to the locking grooves. The bottom wall of the locking groove is provided with a ratchet rack. The locking groove is slidably connected to a locking plate that extends through the locking hole into the inside of the main pipe. The bottom wall of the locking plate is provided with ratchet teeth that mesh with the ratchet rack. A push block is fixedly connected to the end of the locking plate away from the main pipe.
[0022] The beneficial effect of the basic solution is that, through the locking plate that slides within the locking groove, and the ratchet teeth that mesh with each other on the locking plate and the locking groove, medical staff can further push the locking plate to tighten and lock the suture in the main tube, preventing the risk of infection caused by the suture device accidentally falling off.
[0023] Furthermore, a mating platform is fixedly connected to the inner side wall of the main tube, and a "V"-shaped groove with an opening facing the side tube is provided on the upper part of the mating platform. The "V"-shaped groove is located on the movement trajectory of the arc-shaped blade.
[0024] The beneficial effect of the basic scheme is that the mating platform corresponding to the side tube and the "V" shaped groove provided thereon enhance the cutting effect of the arc blade on the suture inside the main tube, and avoid the suture being difficult to cut in some cases, thus affecting the normal sewing process.
[0025] Furthermore, the lower part of the platform is equipped with a hemispherical groove with an opening facing the side tube, and the hemispherical groove is located on the movement trajectory of the resistance hemisphere.
[0026] The beneficial effects of the basic scheme are: the combination of the resistance hemisphere and the hemisphere groove can increase the contact area when the resistance hemisphere locks the suture, thereby enhancing the locking effect of the resistance hemisphere and avoiding the risk of infection caused by the suture loosening and falling off during and after suturing.
[0027] Furthermore, a resistance layer is laid inside the hemispherical groove.
[0028] The beneficial effects of the basic scheme are: by combining the resistance layer and the resistance hemisphere, the locking effect of the resistance hemisphere is further enhanced, thereby improving the stability of the suture device. Attached Figure Description

[0033] The following detailed description illustrates the specific implementation method:
[0034] Example 1
[0035] The basics are as follows: Figure 1 , Figure 2 and Figure 3 The following describes a venous puncture hemostasis suture device: A main tube 23 has threads on its outer top wall. A top cover 9 is fitted onto the top of the main tube 23, with the inner wall of the top cover 9 threadedly engaging with the outer top wall of the main tube 23. The top cover 9 ensures the cleanliness of the inside of the main tube 23. A pressure plate 2 is integrally formed at the bottom of the main tube 23, with a guide wire opening on the pressure plate 2, connecting to the main tube 23. Several guide wire grooves 17 extend radially from the guide wire opening to the outer periphery of the pressure plate 2 on the bottom wall of the pressure plate 2. Several air passage holes 19 are formed on the pressure plate 2 between the guide wire grooves 17. An annular medicine groove 3 is formed inside the pressure plate 2, and a breathable fiber ring sheet 16 is laid inside the medicine groove 3. A side tube 24 is integrally formed on the side wall of the main tube 23. The side tube 24 has threads on its outer periphery. The end of the side tube 24 away from the main tube 23 is fitted with a side cover 13. The inner wall of the side cover 13 is threaded with the outer periphery of the side tube 24. The top wall of the side cover 13 has several air holes 15 corresponding to the side tube 24. The side cover 13 has an integrally formed sliding column 14 extending into the side tube 24. The end of the sliding column 14 near the main tube 23 is rotatably connected to a rotating column 12. The end of the rotating column 12 away from the sliding column 14 is pin-connected to a pusher plate 11. Both the sliding column 14 and the pusher plate 11 are slidably engaged with the inner wall of the side tube 24. An arc-shaped blade 10 parallel to the inner wall of the main tube 23 is attached to the upper part of the pusher plate 11. A resistance hemisphere parallel to the inner wall of the main tube 23 is attached to the upper part of the pusher plate 11.
[0036] The inner wall of the main tube 23 is integrally formed with a mating platform 7. The upper part of the mating platform 7 has a "V" shaped groove 8 with an opening facing the side tube 24, and the lower part of the mating platform 7 has a hemispherical groove 5 with an opening facing the side tube 24. The "V" shaped groove 8 is located on the movement trajectory of the arc-shaped blade 10, and the hemispherical groove 5 is located on the movement trajectory of the resistance hemisphere. A resistance layer 6 is laid in the hemispherical groove 5. The stability of the resistance hemisphere in locking the seam is enhanced by the cooperation between the resistance layer 6 and the resistance hemisphere.
[0037] The top wall of the compression plate 2 has symmetrical locking grooves 18, and the bottom side wall of the main tube 23 has locking holes 4 corresponding to the locking grooves 18. The bottom wall of the locking groove 18 is integrally formed with a ratchet rack 22. The locking groove 18 is slidably connected to a locking plate 20 that extends through the locking hole 4 into the interior of the main tube 23. The bottom wall of the locking plate 20 is integrally formed with ratchet teeth that mesh with the ratchet rack 22. The end of the locking plate 20 away from the main tube 23 is integrally formed with a push block 21, which allows medical staff to push the locking plate 20 with their fingers.
[0038] The specific implementation process is as follows: After suturing, the medical staff unscrews the top cover 9 on the main tube 23 of the suture device, and then passes the suture thread through the guide hole 1 on the pressure plate 2 through the main tube 23 and out of the top of the main tube 23. Pulling the suture and the suture device tightens the suture, and the suture is tightly stored in the guide groove 17, which enhances the fit of the pressure plate 2 to the wound skin. The pressure plate 2 presses against the wound, and the medical staff pinches the push blocks 21 on both sides of the main tube 23 to push the locking plates 20 on both sides through the locking holes 4 in the locking groove 18 to clamp the suture in the main tube 23. The locking plates 20 are locked by the one-way movement between the ratchet teeth and the ratchet rack 22.
[0039] After the suture is initially locked, the medical staff rotates the side cover 13 to push the sliding column 14 and the rotating column 12, and pushes the arc-shaped blade 10 and the resistance hemisphere on the push plate 11 into the main tube 23 in parallel. The resistance hemisphere and the hemispherical groove 5 set at the lower part of the mating table 7 lock the suture in place. The arc-shaped blade 10 works in conjunction with the "V"-shaped groove 8 set at the upper part of the mating table 7 to cut the suture above the locked position, eliminating the need for the medical staff to cut the remaining suture with scissors and enhancing the smoothness of the suturing process.
[0040] After suturing, the suture device remains on the patient's wound surface. On the one hand, the suture device can continuously tighten the suture to ensure wound closure and prevent infection; on the other hand, the reaction force of the suture after locking onto the suture device forms a pressure on the wound skin through the pressure plate 2, promoting hemostasis and healing of the wound and protecting the wound. In addition, the air vent 19 on the pressure plate 2, together with the medicine on the breathable fiber ring 16 in the medicine tank 3, can spray the medicine onto the wound skin to promote hemostasis and healing. The air vent 19 and the breathable fiber ring 16 can improve the air permeability of the wound skin while avoiding contamination by external pathogens, thus preventing anaerobic bacterial infection of deep wounds.
