Description

Technical Field

[0001] This utility model relates to the field of medical protective technology, and more specifically, to a fistula puncture protection device. Background Technology

[0002] Arteriovenous fistula (AVF) puncture is a key technique in hemodialysis treatment, primarily used to establish effective vascular access for patients with end-stage renal disease. The specific procedure involves disinfecting the puncture site, inserting a needle into the fistula vessel, drawing blood out of the body, purifying it through a dialysis machine, and then reinfusing it into the body. Because the AVF is a dialysis patient's "lifeline," the puncture procedure requires a high degree of standardization and aseptic technique to avoid complications such as infection, thrombosis, stenosis, and aneurysm.

[0003] Currently, the number of hemodialysis patients is enormous, placing a heavy workload on nurses. If a patient becomes agitated or involuntarily raises their arm, the risk of the puncture needle slipping increases. Furthermore, using sterile towels to pad the hand makes it difficult to observe the needle's fixation and lacks warmth. Additionally, nurses must check on patients hourly for fistula punctures, making it impossible to monitor the puncture site in real time. This hinders timely intervention in case of accidents, significantly increasing the dialysis risks for patients.

[0004] In conclusion, how to provide a fistula puncture protection device that is easy to observe and reduces the risk of puncture for patients is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a protective device for arteriovenous fistula puncture, which can effectively protect patients during the puncture process, issue an alarm in case of emergency, remind nurses to check in time, and reduce the dialysis risk for patients.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The core of this invention is to provide a protective device for arteriovenous fistula puncture, which effectively protects the patient during the puncture process. In case of emergency, it can issue an alarm to remind the nurse to check in time and reduce the patient's dialysis risk.

[0031] Please refer to Figure 1 An arteriovenous fistula puncture protection device includes a base 1, a detection component 4, and a protective component 5. The base 1 has a groove 3 and is hollow. A fixation member 2 for fixing the patient's arm is installed in the groove 3 and mounted on the base 1. The detection component 4 includes a blood detection device 401, an alarm device 403, and a control board 406 mounted on the base 1. The blood detection device 401 and the alarm device 403 are electrically connected to the control board 406. The protective component 5 includes at least two protective plates 501, which are mounted on the base 1 and located on both sides of the groove 3.

[0032] It should be noted that in the embodiments of this utility model, the pad 1 can adopt a cylindrical, rectangular or polygonal shell structure.

[0033] In addition, the control board 406 in this embodiment of the present invention can be a microcontroller or a CPU board.

[0034] In addition, the alarm device 403 in this embodiment of the present invention may be a buzzer.

[0035] In addition, the blood detection device 401 in this embodiment of the present invention can be a chemiluminescence detector, which uses chemiluminescence reaction to detect specific components in blood. It has high sensitivity and is often used for the detection of trace amounts of blood.

[0036] In addition, the volume of the hollow structure of the pad 1 in this embodiment can be selected according to the material of the pad 1, and the hollow structure can reduce the patient's discomfort to a certain extent.

[0037] In use, both the detection component 4 and the protective component 5 are installed on the base 1. The base 1 has a groove 3, and the interior of the base 1 is hollow. A fixing member 2 for fixing the patient's arm is installed in the groove 3. The groove 3 is used for the patient to place their arm, which can prevent the patient's arm from shaking to a certain extent and can support the patient's arm, reducing the discomfort caused by the patient's arm being suspended for a long time. The fixing member 2 is used to fix the patient's arm, further reducing the patient's involuntary shaking of the arm and reducing the risk of the puncture needle falling off. The detection component 4 includes a blood detection device 401, an alarm device 403, and a control device installed on the base 1. Plate 406, blood detection device 401, and alarm device 403 are all electrically connected to control board 406. The protective component 5 includes at least two protective plates 501, which are installed on pad 1 and located on both sides of groove 3. That is to say, the two protective plates 501 can further enhance the effect of fixing and protecting the patient's arm, and work with blood detection device 401 to monitor bleeding during puncture in a timely manner. When blood detection device 401 detects blood, it feeds back to control board 406, and control board 406 controls alarm device 403 to sound an alarm, reminding nurses to check in time and reduce the patient's dialysis risk.

[0038] It should be noted that the cushion 1 in this embodiment of the present invention can be made of any material. Specifically, in order to improve the patient's comfort, the cushion 1 can be made of soft material, such as rubber, silicone, etc.

[0039] In addition, the groove 3 in this embodiment of the present invention can be of different sizes, for example, different sizes for male and female patients, or the width of the groove 3 can be variable by means of the material properties of the pad 1 itself, which is beneficial to the clamping effect on the patient's arm and further improves the fixation effect on the patient's arm.

[0040] In addition, in this embodiment of the present invention, the blood detection device 401 can be a bleeding detection device 401, such as a wireless bleeding monitoring device, for example, Sensora, where the wireless sensor can be attached near the wound to monitor the bleeding in real time and transmit data via Bluetooth, or an optical bleeding detection device 401, for example, Tissue Analytics, which uses optical imaging technology to analyze the bleeding in the wound, and different models can be selected according to the usage.

[0041] Optionally, in some embodiments, a flow channel 6 made of silicone material is provided in the groove 3. The flow channel 6 is funnel-shaped, and the blood detection device 401 is located at the bottom of the flow channel 6. That is, when bleeding occurs during the patient's puncture, the blood flows through the flow channel 6 to the blood detection device 401. After detecting bleeding, the blood detection device 401 controls the alarm device 403 to work through the control board 406, which can promptly improve the medical staff's attention to the patient's condition, greatly reduce the risk of the patient's puncture, and improve the safety of the puncture process.

[0042] It should be noted that the flow channel 6 in this embodiment of the present invention may also be made of other materials, and the flow channel 6 may also be in other shapes, as long as it ensures that the permeated blood is guided to the blood detection device 401.

[0043] In other embodiments, in order to monitor and control the bleeding site more quickly, the blood detection device 401 adopts an infrared or light-sensitive blood detection device 401 and is positioned directly in front of the puncture site. When an abnormality occurs at the puncture site, an alarm can be issued in a timely manner, which helps to further reduce the damage caused by bleeding and ensure the safety of the patient's puncture process.

[0044] Optionally, in some embodiments, in order to reduce the risk of cross-infection caused by patients using the device, the flow channel 6 may be replaced with a disposable product, such as a structure made of low-cost materials like foam, thereby reducing the safety of device use and lowering the risk of cross-infection.

[0045] In the above embodiment, a placement hole communicating with the hollow interior of the pad 1 can be opened at the bottom of the groove 3. The guide groove 6 can be placed in the placement hole to realize the installation of the guide groove 6, which is convenient, quick and easy and has a lower cost of use.

[0046] Optionally, in some embodiments, in order to reduce cross-infection caused by patients using the device, a blood-oozing sheet is provided above the drainage channel 6. The blood-oozing sheet is detachably installed on the pad 1. That is, the blood-oozing sheet separates the patient's skin from the pad 1, avoiding direct contact between the patient and the pad 1. When different patients use the device, different blood-oozing sheets can be replaced, which greatly ensures the safety of the device during use and avoids cross-infection between patients.

[0047] In the above embodiments, the bleeding pad is a medical product used to detect and monitor bleeding from wounds, catheter insertion sites, or other medical procedures. It is typically a thin sheet material that can be placed near the wound or catheter and indicates whether bleeding has occurred through color changes, humidity sensing, or other mechanisms. Therefore, the presence of bleeding can also be determined by observing the state of the bleeding pad.

[0048] Optionally, in some embodiments, the protective plate 501 is hinged to the pad 1. The rotatable protective plate 501 allows the protective plate 501 to rotate to an unprotected position when the patient is being punctured, thus avoiding any impact on the nurse's puncture. After the puncture is completed, the nurse rotates both protective plates 501 to the protected position, that is, the two protective plates 501 rotate close to each other to protect the patient's arm and prevent the puncture site from being squeezed.

[0049] Optionally, in some embodiments, the protective plate 501 is hinged to the pad 1 via a hinge, and the position of the protective plate 501 is fixed after rotation by damping rotation.

[0050] Optionally, in some embodiments, the two protective plates 501 are provided with limiting members. Specifically, a connecting rope is fixed on one of the protective plates 501 and a hook is fixed on the other protective plate 501. When the two protective plates 501 need to be brought close together, the connecting rope is connected to the hook to fix the position of the two protective plates 501.

[0051] In other embodiments, Velcro can be installed at the end of the connecting rope, and another half of the Velcro can be installed on the protective plate 501 to make it easier to fix and separate the two protective plates 501.

[0052] In other embodiments, the two protective plates 501 rotate to a maximum angle of parallel to each other, that is, by increasing the height of the pad 1, the patient's arm is protected.

[0053] In other embodiments, to further enhance the protection of the patient's arm, when the two protective plates 501 are in the protective position, the two protective plates 501 are in contact with each other and form a V-shaped structure to ensure the protective effect on the patient's arm.

[0054] To further facilitate observation of the patient's puncture site, in some embodiments, the protective plate 501 is made of transparent material. That is, the protective plate 501 is made of transparent material, so even when the protective plate 501 is in the protective position, it is still convenient for nurses to quickly observe the patient's puncture site.

[0055] Please refer to Figure 1 To improve patient comfort during the puncture process, especially in winter, in some embodiments, the protective component 5 also includes a heating pad 502 located in the groove 3. That is, the heating pad 502 keeps the patient's arm warm, reducing discomfort caused by prolonged exposure of the patient's arm during puncture, and greatly improving patient comfort during puncture.

[0056] Optionally, in some embodiments, a heating wire can be used instead of the heating pad 502. The heating wire is placed inside the pad 1, and the patient's arm is warmed by heating the entire pad 1.

[0057] Please refer to Figure 1 The detection component 4 also includes a temperature sensor 402, which is installed in the groove 3. The temperature sensor 402 monitors the temperature of the pad 1 and is connected to the control board 406 so that the control board 406 can automatically control and adjust the temperature of the heating pad 502, simplifying the use of the device.

[0058] In other embodiments, the temperature sensor 402 may be mounted on the surface of the pad 1, i.e., at the position where the pad 1 contacts the patient's arm, so that the value detected by the temperature sensor 402 is closer to the temperature value felt by the patient, which is more conducive to improving the patient's comfort during use.

[0059] Please refer to Figure 1 The detection component 4 also includes a display screen 405 and a control key 404. The display screen 405 is mounted on the base 1 and electrically connected to the control board 406. The control key 404 is mounted on the base 1 and electrically connected to the control board 406. The control key 404 is used to adjust the temperature and blood detection device 401 values ​​and displays them in real time on the display screen 405, which is more convenient for users to use the device.

[0060] In other words, the key point of this utility model embodiment is: using a base 1, and concentrating the components on the base 1, with a groove 3 on the base 1, and a fixing member 2 for fixing the patient's arm inside the groove 3. The groove 3 is used for the patient to place their arm inside, which can prevent the patient's arm from shaking to a certain extent, and can support the patient's arm, reducing the discomfort caused by the patient's arm being suspended for a long time. The fixing member 2 is used to fix the patient's arm, further reducing the situation of the patient shaking their arm involuntarily, and reducing the risk of the puncture needle falling off. The detection component 4 includes a blood detection device 401, an alarm device 403 and a control device installed on the base 1. The plate 406, blood detection device 401, and alarm device 403 are all electrically connected to the control board 406. The protective assembly 5 includes at least two protective plates 501, which are installed on the pad 1 and located on both sides of the groove 3. In other words, the two protective plates 501 can further enhance the fixation and protection of the patient's arm. In addition, in conjunction with the blood detection device 401, the bleeding during the puncture process can be monitored in a timely manner. When the blood detection device 401 detects blood, it feeds back to the control board 406. The control board 406 controls the alarm device 403 to sound an alarm, reminding the nurse to check in time and reduce the patient's dialysis risk.
