Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a negative pressure suction therapeutic apparatus for venous congestion of skin flaps. Background Art

[0002] Venous congestion of skin flaps is a common complication after microvascular anastomosis, which is manifested as the inability of venous blood in the skin flap area to return normally, resulting in local congestion. If not treated in time, the congestion condition will further deteriorate, possibly leading to venous obstruction and ultimately skin flap necrosis. This pathological process develops rapidly and poses a serious threat to the tissue health of patients.

[0003] Currently, the treatment methods for venous congestion of skin flaps mainly include leech therapy, drainage tube method, and surgical exploration. However, these methods all have limitations to varying degrees. Although leech therapy can effectively suck out congestion, its particularity often causes fear and nausea in patients, reducing the comfort of treatment. The drainage tube method may lead to poor healing of skin flaps and increase the difficulty of postoperative recovery. Surgical exploration not only brings trauma of secondary surgery to patients, but sometimes may not be necessary because not all congestion situations require surgery to solve.

[0004] In view of the deficiencies of the existing treatment methods, there is an urgent need in the market for a more safe, effective, and easy-to-operate treatment device for venous congestion of skin flaps. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a negative pressure suction therapeutic apparatus for venous congestion of skin flaps, which provides a more safe, effective, and easy-to-operate treatment method for venous congestion of skin flaps, fills the deficiencies of the existing treatment methods in the market, and brings better treatment effects and comfort to patients.

[0006] The technical solution of the utility model is as follows:

[0007] A negative pressure suction therapeutic apparatus for venous congestion of skin flaps includes a main suction tube, a cutter head, and a small tube. One end of the main suction tube is used to connect with a wall suction device, and a cutter head is arranged inside the other end of the tube. The cutter head can be pushed and pulled along the direction of the main suction tube so that the end of the cutter head passes through the end of the main suction tube.

The small tube inside the main suction tube is arranged at one end of the main suction tube where the cutter head is located, and the small tube outside the main suction tube is used to connect with a hanging bottle filled with anticoagulant solution.

[0008] The cutter head is fixedly connected to the end of a rod, and the rod is connected to a push-pull switch through a connecting plate. The push-pull switch is arranged outside the main suction tube; a guiding groove matched with the connecting plate is arranged on the side wall of the main suction tube.

[0009] A sealing cover for sealing the guiding groove is arranged on the outer side of the main body suction tube. The sealing cover is made of an elastic material and fixedly connected to the main body suction tube.

[0010] A protective cap A is installed at the end of the main body suction tube where the cutter head is installed.

[0011] A protective cap A is also installed at the other end of the main body suction tube.

[0012] A protective cap B is installed at the end of the small tube connected to the hanging bottle containing the anticoagulant solution.

[0013] The material of the main body suction tube is transparent or semi - transparent medical - grade plastic.

[0027] As Figure 1 shown, the flap venous congestion negative pressure suction therapy device mainly consists of the following three parts: the main body suction tube 1, the cutter head and the operating mechanism, and the anticoagulant solution delivery system.

[0028] The main body suction tube 1 (main duct): As the core component of the therapy device, one end of the main duct is designed as an interface for connecting to the wall suction device, and the other end is internally provided with a movable cutter head 3. The main duct is made of transparent or semi-transparent medical-grade plastic, which not only has good biocompatibility but also enables medical staff to clearly observe the internal situation, ensuring the accuracy and safety of the treatment.

[0029] The cutter head and the operating mechanism: The cutter head 3 is in the shape of a small triangular bayonet and is fixedly connected to the end of the metal rod 4. The metal rod 4 is connected to the push-pull switch 6 through the connecting plate 5, and the push-pull switch 6 is arranged on the outside of the main duct 1 for easy operation by medical staff. When the catheter is placed in the flap congestion area, by pushing the triangular knife switch (i.e., the push-pull switch 6), the cutter head 3 can easily penetrate the flap to achieve precise treatment.

[0030] The anticoagulant solution delivery system: This system consists of a small tube 8 (a small catheter built inside and outside the main duct) and an infusion bottle containing the anticoagulant solution connected thereto. The small tube 8 is fixed on the main duct 1 and passes from the outside to the inside of the main duct to ensure that the anticoagulant solution can be continuously and stably dripped into the treatment area, effectively preventing blood coagulation and preventing the interruption of the treatment.

[0031] The working process of this flap venous congestion negative pressure suction therapy device is as follows:

[0032] Negative pressure suction treatment: After connecting the main catheter to the wall suction device, adjust it to an appropriate suction pressure. Under the action of negative pressure suction, continuous treatment can be carried out on the congested area of the skin flap.

[0033] Blade head operation and congestion suction: Medical staff can control the metal rod 4 to drive the blade head 3 to push and pull along the direction of the main catheter 1 by operating the push-pull switch 6. When the end of the blade head 3 passes through the end of the main catheter 1, it can penetrate into the congested area of the skin flap. The congestion is effectively sucked out under the action of negative pressure suction to achieve the treatment effect.

[0034] Anticoagulant solution delivery: After connecting the small tube 8 to the drip bottle, the anticoagulant solution will drip into the treatment area from the inner side of the small tube 8 to ensure the continuity and effectiveness of the treatment.

[0035] Other detailed designs:

[0036] Protective cap A2: Protective caps A2 are installed at both ends of the main catheter 1 to prevent contamination and damage in the non-use state. When the treatment device is not in use, the protective cap A2 can tightly cover the port of the main catheter 1 to ensure the cleanliness and safety of the internal environment.

[0037] Protective cap B9: A protective cap B9 is also installed at the end of the small tube 8 connected to the drip bottle to prevent contamination and damage in the non-use state. The protective cap B9 can tightly cover the port of the small tube 8 to prevent the leakage of the anticoagulant solution or the entry of impurities.

[0038] The protective cap A2 and the protective cap B9 can be made of elastic materials and are sleeved on the corresponding ports through elasticity.

[0039] Sealing cover 7: A sealing cover 7 for preventing air leakage in the guide groove is provided on the outer side of the main catheter 1. The sealing cover 7 is made of elastic material and is tightly fixed on the main catheter 1 to cover the guide groove, ensuring the airtightness of the gas during negative pressure suction, preventing gas from leaking from the guide groove and affecting the effect of negative pressure suction; at the same time, it also allows the push-pull switch 6 to slide inside it.

[0040] Guide groove and connecting plate: A guide groove matching with the connecting plate 5 is provided on the side wall of the main catheter 1. The cooperation between the connecting plate 5 and the guide groove is a tight fit, ensuring the stability and accuracy of the blade head 3 during movement. At the same time, the design of the guide groove can also guide the connecting plate 5 and the metal rod 4 to move in the correct direction, avoiding the deviation or jamming of the blade head 3 during movement.

[0041] The blade head 3 is a triangular pyramid structure; the cross-section of the three edges of the blade head 3 is in the shape of a "crescent" arc; the blade head 3 can expand the wound after penetration and will not produce airtightness.

[0042] This treatment device adopts a disposable design and is destroyed after each patient uses it. This design not only avoids the risk of cross-infection but also ensures the safety and hygiene of the treatment. At the same time, all components of the treatment device are made of medical-grade materials, with good biocompatibility and durability.

[0043] In summary, the flap venous congestion negative pressure suction treatment device of the present invention provides a new solution for the treatment of congestion after microvascular anastomosis with its unique structural design, simple operation process, excellent treatment effect, and the safety of single-use.
