Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a linkage device for blood pressure measurement and infusion set closure for preventing thrombosis during breast cancer surgery for patients. Background Art

[0002] For breast cancer surgery, especially for patients who have undergone axillary lymph node dissection, it is usually recommended to avoid intravenous infusion and blood pressure measurement on the upper limb on the surgical side. According to the requirements, the main reason for prohibiting intravenous infusion on the affected side (i.e., the surgical side) during adenocarcinoma surgery is mainly related to the impact of the surgery on local blood circulation and the lymphatic system. The specific reasons are elaborated as follows: 1. Lymphatic reflux disorder: Breast cancer surgery usually includes axillary lymph node dissection, resulting in obstruction of lymphatic reflux in the upper limb on the affected side after surgery. If intravenous infusion is performed on the affected side at this time, it may exacerbate the condition of lymphedema because the additional fluid may not be effectively drained and thus accumulates in the tissue space.

[0003] 2. Poor venous return: During the surgical process, especially operations involving the axillary region, it may damage or compress the venous vessels, affecting blood return. In this case, intravenous infusion on the affected side not only cannot effectively deliver drugs throughout the body, but may also cause local blood stasis and increase the risk of thrombosis.

[0004] 3. Increased risk of edema: Intravenous infusion on the affected side will cause more fluid to enter the already damaged lymphatic and venous systems, further exacerbating the possible limb swelling problem after surgery. In the long run, this persistent edema will affect the patient's comfort and is not conducive to the recovery of upper limb function.

[0005] 4. Increased complications: Intravenous infusion on the affected side can increase the occurrence of local irritation, infection and other potential complications caused by needle insertion. For example, improper operation may cause skin damage, further increasing the possibility of infection.

[0006] 5. Conflict with the disinfection scope: In some surgical procedures, the upper limb on the affected side needs to be disinfected and maintained in a sterile state to cooperate with the intraoperative body position placement, so intravenous infusion cannot be performed on the upper limb on the surgical side. In addition, if any problems occur during the infusion process (such as leakage), it cannot be observed under the sterile drape.

[0007] 6. Interference with complication monitoring: It is crucial to closely monitor whether the patient develops complications such as lymphedema after surgery. If intravenous infusion is selected on the affected side, any local swelling caused by the infusion may be misjudged as a postoperative complication, thus interfering with the doctor's accurate assessment of the disease changes.

[0008] Patients who have undergone breast cancer surgery, especially those who have received axillary lymph node dissection, are at high risk of venous thromboembolism (VTE). VTE encompasses deep venous thrombosis (DVT) and pulmonary embolism (PE). DVT refers to the abnormal clotting of blood in the deep veins, leading to impaired venous return, most commonly in the lower extremities. Once a venous thrombus detaches and travels through the bloodstream to the lungs, it may block the main pulmonary artery or its branches, triggering PE. Depending on the degree of pulmonary circulation impairment, PE can present with a variety of clinical symptoms. The main adverse consequences of DVT include PE and post-thrombotic syndrome, which significantly affect the patient's quality of life and may lead to death.

[0009] Infusion in the lower extremities increases the risk of VTE for the following reasons: 1. Infusion in the lower extremities involves venipuncture, which may cause local skin damage, thereby increasing the chance of bacterial invasion and infection. Given that breast cancer treatment may lead to an immunosuppressed state, any additional source of infection should be taken seriously.

[0010] 2. Considering patient comfort, for some patients, due to the impact of the disease or treatment, lower extremity movement is restricted or accompanied by discomfort. Choosing the lower extremities for infusion may reduce the patient's comfort. In addition, if the patient has leg pain or other related symptoms, the choice of the lower extremities as the infusion site needs to be more cautious.

[0011] 3. Considering the convenience of medical procedures and patient safety, to prevent the formation of lower extremity thrombi during breast cancer surgery while ensuring patient safety, medical staff will move the lower extremities to promote blood return. It may be a more reasonable choice to choose the upper extremity rather than the lower extremity for infusion to facilitate the operation of medical staff.

[0012] In summary, breast cancer surgery patients should choose the healthy upper extremity for infusion during the operation and postoperative rehabilitation. However, in breast cancer surgery, it is inevitable to perform both infusion and blood pressure measurement on the healthy upper extremity simultaneously. When measuring blood pressure, the pressure generated by the cuff will inevitably affect the infusion, causing blood to flow back into the infusion tubing and easily forming thrombi. To solve the conflict between infusion and blood pressure measurement, a linkage device for blood pressure measurement and infusion closure for preventing thrombus formation in breast cancer surgery patients is invented to solve the above technical problems.

[0055] In some embodiments, the cuff 2 is connected with a plug one 20.

[0056] In some embodiments, the base 3 is connected with a plug two 300.

[0057] In some embodiments, the limit post 1 is located on one side of the lead screw 80.

[0058] During use, avoid the infusion tube contacting the lead screw 80, prevent the infusion tube from contacting the lead screw 80 during the process of adjusting the opening and closing of the infusion tube, avoid the risk of damage to the infusion tube caused by mechanical movement, thereby improving the safety of the infusion process and ensuring the smooth progress of the infusion process.

[0059] In some embodiments, the distance between the two limit posts 1 is 6 cm to 8.5 cm.

[0060] During use, the infusion tube is positioned between the two limit posts 51, effectively eliminating the hidden danger that the infusion tube may shift or fall out of the clamping range due to the unconscious limb movements of the patient after surgery. When the clamping part does not clamp the infusion tube, the infusion tube can move smoothly between the two limit posts.

[0061] Working principle: The monitor 1 serves as the core control hub, and the built-in controller plays a key role. It is plugged into the plug one 20 of the cuff 2 through the blood pressure measurement socket 10 to establish an electrical connection, thereby monitoring the working dynamics of the cuff 2 in real time. At the same time, the monitor 1 is plugged into the plug two 300 of the base 3 through the adjustment socket 11 to achieve control over the clamping part. The battery 31 in the accommodation chamber 30 of the base 3 provides power for the stepper motor 8 to ensure the stable operation of the clamping part. The blood pressure measurement unit and the adjustment part are integrated on the monitor 1. The designs of the blood pressure measurement socket 10 and the adjustment socket 11 facilitate quick disassembly and portability by medical staff when needed, improving the flexibility of medical services. The monitor 1 controls the cuff 2 to work through the controller. When the cuff 2 starts to work, it transmits a signal to the controller of the monitor 1. After receiving the signal, the controller issues an instruction to drive the clamping part to start operating, thereby controlling the opening and closing state of the infusion tube. Specifically, during the patient's infusion process, the infusion tube passes through the gap between the trapezoidal plate 5.0 and the fixed plate 50, as well as the area defined by the two limit posts 51. Before that, according to the actual size of the infusion tube, the initial state of the clamping part is preset, that is, the distance between the limit post 51 and the fixed plate 50 is adjusted to be less than the outer diameter of the infusion tube. In this way, the infusion tube can be firmly located between the two limit posts 51, effectively eliminating the hidden danger that the infusion tube may shift or fall out of the clamping range due to the unconscious limb movements of the patient after surgery, and comprehensively improving the safety of the device during use. The upper edge length of the trapezoidal plate 5.0 is less than the lower edge length of the trapezoidal plate 5.0, which can reduce its swing during use, thereby increasing the stability of the entire device. The clamping of the infusion tube is achieved under the control of the controller. The controller controls the stepper motor 8 to operate. The output shaft 8 of the stepper motor rotates and drives the lead screw 80 to rotate synchronously. As the lead screw 80 rotates, the connecting rod one 61, the connecting rod two 62, the connecting rod three 63, and the connecting rod four 64 move in a coordinated and orderly manner. Moreover, the unique V-shaped design of the connecting rod four 64 cleverly avoids the collision with the connecting rod one 61 during the movement process. The limit post 51 is inserted into the jack 52, the trapezoidal plate 5.0 approaches the fixed plate 50, and the trapezoidal plate 5.0 and the fixed plate 50 cooperate to firmly clamp the infusion tube, effectively reducing the adverse impact of blood pressure measurement on infusion and preventing the occurrence of blood reflux phenomenon from the root cause, ensuring the smooth progress of the operation and the safety of the patient. When the cuff 2 is not working, the clamping part returns to the set initial state. Example 2: For Example 2 of the present invention, Figure 11 is described.
