Description

Technical Field

[0001] The present application relates to the technical field of blood vessel puncture and fixation, and in particular to a hemodialysis internal fistula blood vessel puncture, fixation and monitoring device. Background Art

[0002] With the increasing number of hemodialysis patients and the prolonged duration of dialysis, AVF dysfunction has become the main reason for hospitalization and reoperation in hemodialysis patients. The difficulty in puncturing internal fistulas due to their difficult fixation makes puncture difficult. Repeated punctures can lead to thrombosis or stenosis of the internal fistulas, and even puncture complications such as bleeding, hematoma compression, and fistula infection. Bleeding from the puncture site leads to excessive blood loss, difficult-to-correct anemia, and compromised vascular perfusion, ultimately causing AVF dysfunction.

[0003] Currently, during hemodialysis, medical staff are unable to accurately locate the puncture site and needle insertion depth. Furthermore, due to a shortage of medical staff, one-on-one management between medical staff and patients is not possible, and timely attention cannot be paid to bleeding from the puncture site caused by the patient's arm moving in any direction during dialysis.

However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0072] Refer to the following Figures 1 to 4 To describe a hemodialysis fistula puncture fixation and monitoring device provided according to some embodiments of the present application.

[0073] Example 1

[0074] A hemodialysis internal fistula puncture fixation and monitoring device, comprising:

[0075] The vascular puncture fixing mechanism 1 includes a vascular puncture portion 11, provided with a sensing guide wire 111 and an ultrasonic detection mounting hole 112. The vascular puncture fixing mechanism 1 is used to fix the puncture site of the patient during vascular puncture;

[0076] Ultrasonic detector mechanism 2, detachably disposed in ultrasonic detection mounting hole 112, for measuring blood vessel inner diameter, blood flow velocity, assessing blood vessel condition, and locating puncture site and needle insertion depth;

[0077] The blood leakage alarm mechanism 3 is provided with a connecting hole 31. The end of the sensing guide wire 111 away from the vascular puncture fixing mechanism 1 can be detachably inserted into the connecting hole 31 and connected to the vascular puncture fixing mechanism 1. It is used to detect whether there is blood leakage at the fixed part of the vascular puncture fixing mechanism 1. If blood leakage occurs, an alarm is issued in time.

[0078] Furthermore, the blood vessel puncture unit 11 includes:

[0079] The convex surface 113, the ultrasonic detection mounting hole 112 passes through the blood vessel puncture portion 11 and extends out of the surface of the convex surface 113;

[0080] The concave surface 114 is provided with a sponge pad 115 having a size matching that of the concave surface 114 , and the sensing guide wire 111 is embedded in the sponge pad 115 .

[0081] It should be understood that, based on the above-mentioned feature definitions, since the ultrasonic detection mounting hole directly and unobstructedly connects the convex surface and the blood vessel puncture part, the ultrasonic detector can more accurately evaluate the condition of the punctured blood vessel, locate the puncture site and the needle insertion depth, and reduce detection errors; the convex design can fix the blood vessel and prevent it from slipping to the sides at will, and makes the installation and disassembly of the ultrasonic detector more convenient, and medical staff can complete the detection work more quickly and accurately; the sponge pad provides a soft and tight wrapping for the sensing guide wire, effectively preventing the guide wire from being physically damaged during use, which not only enables the guide wire to detect the puncture port condition in time but also extends its service life; the concave design combined with the sponge pad reduces the pressure of the sensing guide wire on the patient's skin and improves the patient's comfort; the stable placement of the sensing guide wire ensures good connectivity between it and the blood vessel puncture fixation mechanism, thereby ensuring the accuracy and reliability of blood leakage monitoring.

[0082] Furthermore, the blood vessel puncture and fixation mechanism 1 further includes a blood vessel fixing portion 12 , which is disposed on both sides of the blood vessel puncture portion 11 to fix the position of the blood vessel puncture portion 11 .

[0083] It should be understood that, based on the above-mentioned feature definitions, the vascular fixation part significantly enhances the stability of the vascular puncture part during the puncture process, reduces puncture deviation caused by patient movement or muscle tension, and improves the success rate and safety of puncture; because the blood vessel is effectively fixed, the puncture needle can enter the target blood vessel more accurately, reducing damage to surrounding tissues and avoiding repeated punctures as much as possible, improving the accuracy of puncture, and protecting the punctured blood vessel; stable fixation reduces patient discomfort that may be caused by blood vessel movement or twisting during puncture, and improves the patient's overall experience; the design of the vascular fixation part enables medical staff to complete the puncture operation more quickly and accurately, reducing operation time and difficulty, improving work efficiency, and most importantly, reducing the number of punctures for patients and extending the use time of blood vessels.

[0084] Furthermore, the blood vessel fixing portion 12 includes:

[0085] Side wings 121 are provided on both sides of the blood vessel puncture portion 11;

[0086] The adhesive portion 122 is provided on the side of the side wing 121 that contacts the skin;

[0087] The friction portion 123 is disposed on a surface of the side wing 121 opposite to the adhesive portion 122 .

[0088] It should be understood that, based on the above-mentioned feature definitions, the adhesive portion and the friction portion together constitute a dual fixation mechanism for the vascular fixation portion. The adhesive portion ensures that the vascular puncture portion fits tightly against the patient's skin, while the friction portion facilitates the medical staff's holding of the device and prevents sliding when the patient moves or when clothing rubs against it, thereby improving the stability and reliability of the fixation. The adhesive portion is usually made of medical-grade viscose material, which is skin-friendly and reduces irritation and discomfort to the patient's skin. At the same time, the design of the side wings also takes into account the patient's comfort, avoiding overly tight or overly loose fixation. Stable fixation reduces the pulling and twisting of the blood vessels caused by patient movement, helps protect the blood vessels from damage, and also provides good conditions for subsequent puncture and monitoring operations.

[0089] Furthermore, the pasting portion 122 includes:

[0090] Adhesive 1221 covers the side of the side wing 121 that contacts the skin;

[0091] The release paper 1222 covers the surface of the adhesive 1221 .

[0092] It should be understood that, based on the above-mentioned characteristic definitions, the presence of the release paper effectively protects the adhesive from contamination and damage during storage and transportation, ensuring its stickiness during use; the user only needs to peel off the release paper to adhere the adhesive to the patient's skin. This process is simple and quick, improving the convenience of use; the close contact between the adhesive and the skin provides a strong fixing force, allowing the vascular puncture fixation mechanism to remain stable during puncture and monitoring, and is not affected by patient movement or external factors;

[0093] It should be noted that high-quality adhesive materials should use skin-friendly formulas to reduce irritation and discomfort to the patient's skin; in addition, a reasonable adhesive area and layout can also help improve patient comfort; in medical applications, the adhesive and side wing materials should undergo strict sterilization to ensure aseptic operation during puncture and monitoring, reducing the risk of infection.

[0094] Furthermore, the ultrasonic detector mechanism 2 includes:

[0095] A display device for displaying the inner diameter of the blood vessel, blood flow velocity, needle insertion site, and needle insertion depth detected by the ultrasound detector body;

[0096] The ultrasonic detector body 21, the detection end of the ultrasonic detector body 21 is arranged in the ultrasonic detection installation hole 112;

[0097] The connecting wire 22 has one end electrically connected to the ultrasonic probe body 21 and the other end electrically connected to the display device.

[0098] It should be understood that, based on the above-mentioned feature limitations, through the real-time detection of the ultrasound detector body and the intuitive display of the display device, medical staff can evaluate the patient's vascular condition in advance and clearly see the location and depth of the blood vessels, thereby extending the patient's hemodialysis time, reducing the waste of disposable blood purification pipelines and performing more precise puncture operations; this greatly reduces the risk of puncture deviation and improves the success rate and safety of puncture; precise puncture operations mean less damage to surrounding tissues, thereby reducing the patient's pain and discomfort; this is of great significance for improving the patient's overall experience and treatment effect; the use of the ultrasound detector mechanism makes the puncture operation faster and more efficient; medical staff can quickly find blood vessels and perform evaluations and punctures, saving medical staff's valuable time and patient hemodialysis costs, and improving work efficiency; the intuitive information on the display device facilitates communication and understanding between doctors and patients; patients can see their own vascular conditions through the display device and have a clearer understanding of the puncture process, thereby enhancing trust and cooperation between doctors and patients.

[0099] Furthermore, the blood leakage alarm mechanism 3 is a blood leakage monitoring alarm 32, and the connecting hole 31 is provided at one end of the blood leakage monitoring alarm 32; the blood leakage monitoring alarm 32 further includes:

[0100] A microcontroller is provided in the blood leakage monitoring alarm 32;

[0104] The sensor is disposed in the blood leakage monitoring alarm 32 , with one end electrically connected to the microcontroller and the other end electrically connected to the connection hole 31 .

[0105] It should be understood that, based on the above-mentioned feature limitations, the blood leakage monitoring alarm monitors the blood flow in the blood circuit system in real time through sensors. Once an abnormal situation such as blood leakage is detected, the alarm mechanism can be triggered immediately to ensure that medical staff can take quick measures to ensure patient safety; combined with the use of alarm flashing lights and alarm speakers, the blood leakage monitoring alarm provides dual visual and auditory alarm methods to ensure that it can be noticed in time in different environments, thereby improving the reliability and effectiveness of the alarm; the detachable power supply design is convenient for users to replace and maintain; at the same time, the entire blood leakage monitoring alarm has a compact structure and easy operation, which reduces the difficulty of use for medical staff; the use of the blood leakage monitoring alarm effectively reduces the risks to patients caused by abnormal conditions such as blood leakage, and improves the safety and reliability of medical processes such as dialysis.

[0106] Furthermore, the microcontroller includes:

[0110] The alarm whistle module is electrically connected to the alarm speaker, and when the sensor monitoring module receives a blood leakage signal, it drives the alarm speaker to turn on.

[0111] It should be understood that, based on the above-mentioned feature definitions, the central control module uses an efficient algorithm to process the data transmitted by the sensor monitoring module, and can quickly and accurately determine whether there is blood leakage in the blood circuit system, thereby realizing real-time monitoring of blood leakage; once blood leakage is detected, the microcontroller can immediately drive the alarm flashing module and the alarm siren module to send out an alarm signal; this rapid response mechanism helps medical staff to take quick measures to prevent the blood leakage from further deteriorating; combined with the use of alarm flashing lights and alarm speakers, the microcontroller provides dual visual and auditory alarm methods; this design not only improves the reliability of the alarm, but also ensures that it can be noticed in time in different environments; through precise blood leakage monitoring and timely alarm response, the microcontroller plays a key role in the blood leakage alarm mechanism, effectively improving the safety of patients in the process of using blood circuit systems (such as dialysis lines).

[0112] Furthermore, a connector 1111 is provided at one end of the sensing guide wire 111 connected to the connecting hole 31 , and the sensing guide wire 111 is electrically connected to the blood leakage monitoring alarm 32 via the connector 1111 .

[0113] It should be understood that, based on the above-mentioned feature definitions, the use of the connector effectively reduces the signal interruption or distortion problems caused by poor or loose contact, thereby improving the accuracy and reliability of monitoring; the standardized interface design and convenient connection method enable medical staff to easily complete the connection operation between the sensing guide wire and the blood leakage monitoring alarm, reducing the difficulty and complexity of the operation; when the sensing guide wire or the blood leakage monitoring alarm needs maintenance or replacement, the presence of the connector makes this process simpler and faster; medical staff only need to loosen the fixing device and pull out the connector to complete the replacement operation; the stable connection ensures that the blood leakage monitoring alarm can continuously and accurately monitor the blood flow in the blood system, and can immediately issue an alarm signal once an abnormal condition such as blood leakage is detected, thereby improving the safety of the patient.

[0114] Furthermore, a puncture fixing hole 116 is provided on the blood vessel puncture portion 11 .

[0115] It should be understood that, based on the above-mentioned characteristic definitions, by providing a puncture fixing hole on the blood vessel puncture part, it has a certain effect in further fixing the puncture needle for medical staff after puncture.

[0116] Based on all the above technical features of this embodiment, its working principle is as follows:

[0117] The vascular puncture and fixation mechanism 1 utilizes the vascular puncture portion 11 and the vascular fixation portion 12 to secure the patient's puncture site. The convex surface 113 and concave surface 114 of the vascular puncture portion 11 ensure a more stable puncture process. The sponge pad 115 on the concave surface 114 provides a comfortable fit and includes an embedded sensor guidewire 111 for subsequent monitoring. The side wings 121 of the vascular fixation portion 12 are conveniently secured to the patient's skin through the adhesive 1221 and release paper 1222 of the adhesive portion 122. The friction portion 123 enhances the securement effect and facilitates stable use by medical personnel. The ultrasonic detector body 21 of the ultrasonic detector mechanism 2 is inserted into the ultrasonic detector mounting hole 112. The detected image is displayed on a display device, helping medical personnel assess the vascular condition, accurately locate the puncture site, and determine the appropriate needle insertion depth. One end of the sensor guidewire 111 is connected to the vascular puncture portion 11, and the other end is inserted into the connection hole 31 of the blood leakage alarm mechanism 3 through a connector 1111. The sensor in the blood leakage monitoring alarm 32 monitors the signal of the sensor guide wire 111 in real time.
