Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices and relates to a communication device for bridging vascular injuries. Background Art

[0002] Injury to major limb blood vessels caused by severe trauma is a common and critical illness. Patients can experience hemorrhagic shock due to massive bleeding within a short period of time, necessitating urgent medical attention. Improper treatment can not only cause limb ischemia, necrosis, and disability, but in more severe cases, hemorrhagic shock can be life-threatening. Therefore, timely and effective treatment is crucial.

[0003] Traditional first aid measures include applying pressure to stop bleeding, suturing and ligating the bleeding area. Patent CN212281499U discloses a war trauma first aid hemostasis sealing and pressure clamp, including a first clamp body, a second clamp body, a central axis and a positioning pin; the first clamp body includes a first hand-held plate, a first splint, a ring fixed on the same side of the first hand-held plate and the first splint, and a plurality of first clamping needles vertically arranged on the inner wall of the first splint. The war trauma first aid hemostasis sealing and pressure clamp is suitable for treating wounded soldiers under different conditions, including war conditions and acute trauma treatment under normal conditions, and has strong practicality and operability. Patent CN210749366U discloses a leg trauma pressure hemostasis device, including a shell, a clamping handle is installed on the upper end face of the shell, and a threaded column is installed on the lower end face of the clamping handle. The leg trauma pressure hemostasis device can simultaneously apply ice and pressure to the patient's leg trauma, and has strong sealing performance. At the same time, the device has a long service life. Although it can effectively stop bleeding, the above method has some shortcomings:

[0004] (1) Pressure and suture to stop bleeding will lead to interruption of blood supply to the distal limbs, causing ischemia, necrosis and even disability of the distal limbs.

[0005] (2) Currently, most vascular shunt devices are temporary infusion tubes, which are prone to infection and thrombosis risks after placement.

[0006] (3) Currently, temporary vascular shunts are fixed at the broken ends of the blood vessels using ligatures, which poses a risk of the shunt falling off and causing bleeding.

[0007] Therefore, there is an urgent need to design a communication device for bridging vascular damage to solve the current technical problems. Summary of the Invention

[0008] The purpose of the present invention is to address the above technical problems and provide a connecting device for bridging vascular injuries, which has a reasonable structure and is easy to connect, effectively ensuring the normal supply of blood and avoiding limb ischemia, necrosis and disability caused by insufficient blood supply.

[0036] A structural diagram of a communication device for bridging vascular damage described in this application is shown in FIG. Figures 1 to 5 As shown, it includes a bridging tube 10, and a connecting portion 20 is provided at both ends of the bridging tube 10, and the connecting portion 20 is provided between the blood vessel 30 and the bridging tube 10; Figure 3 The branch tube 11 shown provides a channel for blood vessel supply, is used to connect multiple blood vessels or infuse fluid, and preserves the blood supply to the distal limb as much as possible. The branch tube 11 is arranged perpendicular to the axis of the bridging tube 10.

[0037] Furthermore, the connecting portion 20 includes a straight segment 21 and a tapered segment 22. Figure 5 As shown, the two are integrally formed; the outer periphery of the straight section 21 is provided with connecting threads, and the inner sidewall of the end of the bridging tube 10 is provided with connecting threads. The straight section 21 of the connecting portion 20 is threadedly connected to the bridging tube 10; the tapered section 22 of the connecting portion 20 is inserted into the blood vessel 30 and bonded to it. The tapered section facilitates better connection and fit with the blood vessel.

[0038] As an embodiment of the present invention, the main body of the bridge tube 10 is a circular tubular structure made of polyvinyl chloride. In order to prevent infection and thrombosis caused by vascular shunting, the inner and outer walls of the bridge tube 10 are coated with an anticoagulant coating and an antibacterial coating 10a, such as Figure 4 As shown, the thickness of the anticoagulation coating and the antibacterial coating 10a is 0.001-0.01 mm.

[0039] In some embodiments, the anticoagulant coating is a heparinized polyurethane coating, and the antibacterial coating is an Ag ion coating, so as to prevent vascular shunt from causing symptoms such as infection and thrombosis.

[0040] In order to ensure normal blood supply to the vascular injury bridge, the length ratio of the straight section 21 to the tapered section 22 is 1:4 to 1:8. Figure 6 In the embodiment shown, the ratio of L1 to L2 is 1:4 to 1:8.

[0041] Furthermore, the ratio of the outer diameter to the inner diameter of the tapered section 22 is 1:1.5 to 1:3. Figure 6 In the embodiment shown, the ratio of D2 to D1 is 1:4 to 1:8.

[0042] As an embodiment of the present invention, there are multiple branch pipes 11 , which are evenly spaced along the length direction of the bridging pipe 10 . Figure 1 In the embodiment, the number of branch pipes 11 is 4, which are symmetrically arranged on both sides of the main body of the bridge pipe 10. The distance between adjacent branch pipes 11 is 1 / 4-1 / 2 of the length of the main body of the bridge pipe 10.

[0043] As one aspect of this embodiment, the diameter of the branch pipe 11 is 1 / 3-1 / 2 of the diameter of the bridge pipe 10. Preferably, the diameter of the branch pipe 11 is 1 / 2 of the diameter of the bridge pipe 10.

[0044] In order to increase the reliability of fixing the connecting portion 20 to the blood vessel 30 , the outer peripheral side of the tapered section 22 of the connecting portion 20 is coated with an adhesive gel coating, and the thickness of the adhesive gel coating is 0.001-0.01 mm.

[0045] Furthermore, the adhesive gel coating is a cyanoacrylate adhesive, which forms an adhesive upon contact with blood and adheres to the vessel wall, thereby connecting the connector 20 to the vessel 30. Specifically, after the tapered section 22 of the connector 20 is inserted into the vessel 30, the adhesive gel coating forms an adhesive upon contact with blood and adheres to the vessel wall, thereby simplifying the fixation process and reducing the risk of slippage.

[0046] Compared with the shortcomings and deficiencies of the existing technology, the present invention provides a connecting device for bridging vascular injuries, which has a reasonable structure and is easy to connect, effectively ensuring the normal supply of blood and avoiding limb ischemia, necrosis and disability caused by insufficient blood supply.

However, no matter what changes are made in the shape or structure, any product with the same or similar technical solutions as the present application falls within the scope of protection of the present invention.
