Description

Technical Field

[0001] This utility model relates to the field of hemodialysis technology, specifically a real-time monitoring and alarm device for the circulating blood circuit in medical hemodialysis. Background Technology

[0002] In hemodialysis treatment, the safety of the extracorporeal circulation system is crucial and key to ensuring the smooth progress of treatment for patients with acute and chronic renal failure. During dialysis, a vascular access (such as an arteriovenous fistula) is usually established through the patient's ipsilateral upper limb. Extracorporeal circulation tubing is connected to two puncture points on the same vessel: one arterial end, which draws blood out of the body into the dialysis machine; the other venous end, which returns the purified blood to the body. The entire treatment process lasts several hours, during which it is essential to ensure unobstructed blood flow and secure tubing connections. Bleeding or dislodgement at any puncture point can lead to serious complications.

[0003] To ensure treatment safety, modern dialysis equipment is equipped with an integrated intelligent safety monitoring system that can monitor arterial pressure, venous pressure, air embolism, and dialysate abnormalities in extracorporeal circulation in real time, and has corresponding audible and visual alarm functions. These systems act as "safety sentinels," effectively preventing various risks from occurring within the tubing. However, existing monitoring systems mainly monitor the condition inside the dialysis machine and the middle section of the tubing, and cannot cover the tubing connection points near the patient's puncture site.

[0004] Because the puncture site is located on the patient's limb, the dialysis tubing may bend when the patient moves, which may affect the blood flow rate inside the tubing and even cause air bubbles to form inside the tubing. Existing monitoring equipment can only monitor the tubing inside the dialysis equipment, resulting in ineffective safety monitoring at both ends of the tubing, which poses a serious safety hazard to the dialysis process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a real-time monitoring and alarm device for the circulating blood circuit in medical hemodialysis, which can monitor the blood status at both ends of the dialysis tube in real time, thereby improving the safety and stability of the entire hemodialysis process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a real-time monitoring and alarm device for the circulating blood circuit in medical hemodialysis, comprising a binding structure and a monitoring component. The monitoring component includes a first housing and a second housing. The first housing is connected to the binding structure. Two semi-circular grooves are opened on the adjacent side of the first housing and the second housing. The four semi-circular grooves are spliced ​​together to form two circular holes. Sensors are embedded in each of the four semi-circular grooves.

[0007] Furthermore, multiple sensors are embedded within the semi-circular groove.

[0008] Furthermore, connecting plates are fixedly connected to both sides of one end of the first housing, and a shaft is fixedly connected between the two connecting plates. A rotating hole is opened through the side wall of the second housing near the two connecting plates, and the shaft is rotatably connected to the rotating hole. A locking element is connected to the end of the second housing away from the connecting plates.

[0009] Furthermore, the locking component includes an elastic J-rod, a groove is provided on the side of the first housing away from the two connecting pieces, a hook groove is provided on the inner wall of the groove, the elastic J-rod is fixedly connected to the side of the second housing near the groove, and the end of the elastic J-rod away from the second housing is slidably connected to the hook groove.

[0010] Furthermore, the binding structure includes straps and hook and loop fasteners, with the loop side and hook side of the hook and loop fasteners being fixedly connected to the inner and outer sides of both ends of the straps, and the ends of the hook and loop fasteners being connected to the first housing.

[0011] Furthermore, a support plate is connected to the end of the strap, and the end of the support plate extends to the outside of the strap and is fixedly connected to the first housing.

[0012] Furthermore, a connecting plate is embedded on the inner side of the end of the strap, and several connecting posts are fixedly connected to one side of the connecting plate. The other ends of the connecting posts all pass through the strap and are fixedly connected to the support plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This medical hemodialysis circulating blood circuit real-time monitoring and alarm device uses a binding assembly to securely fix the monitoring component to the arm of the hemodialysis patient. The first and second housings of the monitoring component have mutually cooperating semi-circular grooves, which, when closed, form two circular holes for clamping the two ends of the circulating blood circuit. The housings are embedded with sensors that can monitor the blood flowing through the circulating blood circuit in real time, thereby effectively improving the safety and stability of the hemodialysis process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 A real-time monitoring and alarm device for blood circulation in medical hemodialysis includes a binding structure 1 and a monitoring component 2. The monitoring component 2 includes a first housing 3 and a second housing 4. The first housing 3 is connected to the binding structure 1. Two semi-circular grooves 101 are opened on the adjacent side of the first housing 3 and the second housing 4. The four semi-circular grooves 101 are spliced ​​together to form two circular holes. Sensors 5 are embedded in the four semi-circular grooves 101.

[0023] The main improvement of this invention lies in enhancing the safety and stability of hemodialysis, such as... Figures 1 to 5 As shown, in the medical hemodialysis circulating blood circuit real-time monitoring and alarm device of this utility model, after the two ends of the dialysis tube are punctured in the patient's arm, the two ends of the dialysis tube can be tied to the patient's arm using the binding structure 1, thereby improving the stability of the puncture position of the two ends of the dialysis tube in the patient's arm. Then, the two ends of the dialysis tube are respectively placed in the two semi-circular grooves 101 of the first housing 3 of the monitoring component 2. Then, the second housing 4 is placed on the first housing 3, and the two semi-circular grooves 101 of the second housing 4 are used in conjunction with the two semi-circular grooves 101 of the first housing 3 to clamp and fix the two ends of the dialysis tube. The sensors 5 embedded in the inner side of the semi-circular grooves 101 monitor the two ends of the dialysis tube. It should be noted that cavities can be provided inside the first housing 3 and the second housing 4. Batteries, buzzers, and controllers (such as PIC microcontrollers) can be installed in the cavities. The batteries provide power to the buzzers, controllers, and sensors 5. When the sensors 5 detect abnormalities in the blood flow within the dialysis tubing, the buzzers will promptly alert the patient and medical staff, thereby enabling timely detection of abnormalities at both ends of the dialysis tubing and improving the safety and stability of hemodialysis. The batteries, buzzers, and controllers are all common structures in existing portable monitoring devices, so they are not described in detail in this article. Sensor 5 can be an ultrasonic sensor, a photoelectric sensor, or a capacitive sensor, etc.

[0024] like Figures 1 to 3As shown, multiple sensors 5 are embedded in the semi-circular groove 101. By embedding multiple sensors 5 in the semi-circular groove 101, different types of sensors 5 can be used to comprehensively monitor the blood flow inside the dialysis tube through different monitoring methods, thereby further improving the monitoring effect of the dialysis tube.

[0025] like Figures 1 to 4 As shown, connecting pieces 31 are fixedly connected to both sides of one end of the first housing 3, and a shaft 32 is fixedly connected between the two connecting pieces 31. A rotating hole 401 is provided through the side wall of the second housing 4 near the end of the two connecting pieces 31. The shaft 32 is rotatably connected to the rotating hole 401. A locking member is connected to the end of the second housing 4 away from the connecting pieces 31. The connection between the rotating hole 401 at the end of the second housing 4 and the shaft 32 allows the second housing 4 to be flipped between the two connecting pieces 31 of the first housing 3, thereby facilitating the opening of the second housing 4. The end of the dialysis tube is then placed into the semi-circular groove 101. Subsequently, the second housing 4 is placed on top of the first housing 3, and the locking member is used to fix the second housing 4 on the first housing 3 and clamp the end of the dialysis tube, improving the monitoring effect of blood flow in the dialysis tube.

[0026] like Figures 2 to 4 As shown, the locking component includes an elastic J-rod 6. A groove 301 is formed on the side of the first housing 3 away from the two connecting pieces 31. A hook groove 302 is formed on the inner wall of the groove 301. The elastic J-rod 6 is fixedly connected to the side of the second housing 4 near the groove 301, and the end of the elastic J-rod 6 away from the second housing 4 is slidably connected to the hook groove 302. During the process of the second housing 4 covering the first housing 3, the end of the elastic J-rod 6 bends outward by being pressed against the groove 301. When the end of the elastic J-rod 6 moves to the position of the hook groove 302, the elastic J-rod 6 rebounds and hooks its end into the hook groove 302, thus successfully connecting and fixing the second housing 4 to the first housing 3. When it is necessary to open the second housing 4 from the first housing 3, a finger is used to push the end of the elastic J-rod 6 outward through the groove 301, causing the elastic J-rod 6 to bend outward, thereby disengaging the end of the elastic J-rod 6 from the hook groove 302, allowing the second housing 4 to be easily opened from the first housing 3.

[0027] like Figure 1 and Figure 5As shown, the binding structure 1 includes a strap 7 and Velcro 8. The hook and loop sides of the Velcro 8 are fixedly connected to the inner and outer sides of both ends of the strap 7, respectively. The end of the Velcro 8 is connected to the first housing 3. When using the binding structure 1, the end of the strap 7 near the first housing 3 is placed close to the position of the dialysis catheter insertion point on the patient's arm. Then, the end of the strap 7 and the first housing 3 are placed between the dialysis catheter and the patient's arm. The other end of the strap 7 is then wrapped around the patient's arm, and after wrapping it once, the dialysis catheter is wrapped inside. Finally, the Velcro 8 is used to attach and fix it to the patient's arm, thereby fixing both ends of the dialysis catheter to the patient's arm. Then, the two ends of the dialysis catheter are respectively placed into the two semi-circular grooves 101 of the first housing 3, and the second housing 4 is placed on top of the first housing 3, thus completing the fixation operation of the dialysis catheter on the patient's arm.

[0028] like Figure 1 and Figure 2 As shown, a support plate 9 is connected to the end of the strap 7. The end of the support plate 9 extends to the outside of the strap 7 and is fixedly connected to the first housing 3. When the strap 7 is tied to the patient's arm, the support plate 9 ensures that the first housing 3 does not easily shake on the patient's arm after the strap 7 is tied, thus improving the stability of the fixed monitoring of both ends of the dialysis tube.

[0029] like Figures 1 to 5 As shown, a connecting plate 10 is embedded in the inner side of the end of the strap 7. Several connecting posts 11 are fixedly connected to one side of the connecting plate 10. The other ends of the connecting posts 11 all pass through the strap 7 and are fixedly connected to the support plate 9. The connecting plate 10 provides support at the end of the strap 7, making it less likely for the strap 7 to shift on the patient's arm after binding, thus improving the stability of the binding. At the same time, the multiple connecting posts 11 connect and fix the connecting plate 10 to the support plate 9, making the first housing 3 more stable on the patient's arm. In addition, the multiple connecting posts 11 can avoid creating an excessively large perforation area for the strap 7, preventing tearing and damage to the strap 7, and improving the stability of the strap 7 in use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
