Description

Technical Field

[0001] The present invention belongs to the technical field of medical hemostasis, and in particular relates to a hemostasis rescue device for cardiology department. Background Art

[0002] In recent years, the incidence rate of cardiovascular diseases has been continuously rising, and various surgeries and invasive diagnostic and treatment operations in the cardiology department have also increased day by day, such as cardiac pacemaker implantation. While such surgeries bring hope for treatment to patients, they are also accompanied by the risk of bleeding. Once hemostasis is not timely or the effect is not good, serious complications will be caused, endangering the lives of patients. Therefore, a hemostasis rescue device is needed. For example, the publication number: CN117770903A discloses a hemostasis rescue device for the cardiology department.

[0003] At present, most of the hemostasis rescue devices used clinically are pressing-type hemostasis devices. For example, a tourniquet. Due to the differences in the size, shape, and bleeding sites of the surgical wounds of different patients, it is difficult for a hemostasis device with a fixed pressing area to adapt to all patients. When the pressing area is too large, it will cause unnecessary compression on the normal tissues around the wound, leading to local blood circulation disorders, tissue ischemia and hypoxia, and then damage to the surrounding tissues, increasing the risks of postoperative infection, tissue necrosis, etc.; while when the pressing area is too small, it cannot fully and effectively compress the wound, making it difficult to achieve an ideal hemostasis effect, resulting in continuous blood exudation, affecting the healing of the wound, and even possibly triggering more serious bleeding events.

[0004] Therefore, a hemostasis rescue device for the cardiology department is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a hemostasis rescue device for the cardiology department in view of the above problems.

A plugging ring is fixedly arranged on the upper surface of the annular pressing plate. The end of the plugging rod away from the shell is plugged and matched with the inside of the plugging ring.

[0013] Preferably, a pressure sensor is fixedly embedded at the center of the lower surface of the circular pressing plate. The pressure sensor is electrically connected to the PLC controller.

[0014] Preferably, the wound temperature detection mechanism includes an elastic silica gel pressing sheet fixedly arranged inside the circular pressing opening. A plurality of uniformly distributed temperature sensors are fixedly embedded on the lower surface of the elastic silica gel pressing sheet. The positions of the plurality of temperature sensors correspond to the positions of the circular pressing plate and the plurality of annular pressing plates respectively.

[0015] Preferably, the drug release mechanism includes a drug storage box fixedly arranged on the inner side wall of the arc-shaped pressing sleeve.

The output end of the drug pump body is fixedly provided with a rigid drug delivery tube extending to the outside of the drug storage box, and the end of the rigid drug delivery tube adopts a closed structure. A plurality of uniformly distributed soft drug branch tubes are fixedly arranged on the lower side of the pipe wall of the rigid drug delivery tube.

[0019] 2. Through the pressure sensor provided, the pressure sensor can feedback the pressing force of the circular pressing plate and the annular pressing plates in real time and display it on the control panel. Medical staff can dynamically adjust the stroke of the electric push rod according to the data, avoiding the risks such as tissue ischemia and displacement of the pacemaker electrode caused by excessive pressure, and at the same time ensuring effective hemostasis. The closed-loop feedback system realizes the automation of "detection - analysis - execution", reducing the human operation error.

[0020] 3. Through the drug release mechanism provided, after positioning the wound area based on the temperature feedback, the PLC controller triggers the drug pump body, and injects drugs such as recombinant human epidermal growth factor into the drug storage cavity made of PLGA material through the conductive soft drug branch tubes. The porous hydrophilicity of PLGA is utilized to realize continuous diffusion and drug release. The drug acts directly on the healing site, improving the utilization rate and reducing the stimulation to healthy tissues.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] like Figures 1 - 7As shown in the figure, a hemostasis rescue device for the department of cardiology includes an arc-shaped pressing sleeve 1 and fixing straps 2 arranged at both ends of the arc-shaped pressing sleeve 1. At the ends of the two fixing straps 2 away from the arc-shaped pressing sleeve 1, a round felt 3 and a burr felt 4 are respectively arranged. Place the arc-shaped pressing sleeve 1 on the patient's chest, and then wind the two fixing straps 2 around the patient's back. The device is firmly fixed by the close fitting of the round felt 3 and the burr felt 4. A switch cover 11 and a control panel 12 are arranged on the outer side wall of the arc-shaped pressing sleeve 1. The switch cover 11 and the arc-shaped pressing sleeve 1 can be connected by a magnetic adsorption structure. Opening the switch cover 11 opens the internal space of the arc-shaped pressing sleeve 1. It also includes:

[0031] The adjustable-area pressing mechanism 5 is arranged on one inner side of the arc-shaped pressing sleeve 1. The adjustable-area pressing mechanism 5 includes an electric push rod 51 fixedly arranged on the inner wall of the top of the arc-shaped pressing sleeve 1. A circular pressing plate 52 is fixedly arranged at the moving end of the electric push rod 51. A plurality of annular pressing plates 53 sleeved with each other are arranged on the circumferential wall of the circular pressing plate 52. Both the circular pressing plate 52 and the annular pressing plates 53 are made of PLGA plates. Two elastic telescopic rods 54 are symmetrically arranged between the tops of the plurality of annular pressing plates 53 and the inner wall of the top of the arc-shaped pressing sleeve 1. The elastic telescopic rod 54 includes a fixed sleeve 541 fixedly arranged on the inner wall of the top of the arc-shaped pressing sleeve 1. A moving rod 542 is arranged inside the fixed sleeve 541. A first spring 543 is arranged between one end of the moving rod 542 and the inner wall of the fixed sleeve 541. And the other end of the moving rod 542 is fixedly connected to the upper surface of the annular pressing plate 53. The first spring 543 can elastically connect the fixed sleeve 541 and the moving rod 542, so that the plurality of annular pressing plates 53 can be elastically lifted upward; an electromagnetic plugging mechanism 55 is arranged between two adjacent annular pressing plates 53 and between the circular pressing plate 52 and the annular pressing plates 53. The electromagnetic plugging mechanism 55 includes a housing 551 fixedly arranged on the circular pressing plate 52 and the annular pressing plates 53 respectively. An electromagnet 552 is fixedly arranged on the inner side wall of the housing 551. A second spring 553 is fixedly arranged on one side of the electromagnet 552. A permanent magnet 554 is fixedly arranged at the end of the second spring 553 away from the electromagnet 552. A plugging rod 555 is fixedly arranged on the side of the permanent magnet 554 away from the second spring 553. The rod wall of the plugging rod 555 is slidably connected to one side of the housing 551. A plugging ring 556 is fixedly arranged on the upper surface of the annular pressing plate 53. The end of the plugging rod 555 away from the housing 551 is inserted and matched with the inside of the plugging ring 556. When the electromagnet 552 is powered on, a magnetic repulsive force on the permanent magnet 554 is immediately generated. Under the action of the magnetic repulsive force, the permanent magnet 554 drives the plugging rod 555 to move outwards against the elastic force of the second spring 553 until one end of the plugging rod 555 accurately inserts into the inside of the plugging ring 556. Thus, the circular pressing plate 52 and the annular pressing plates 53 around it are connected as a whole. When the electromagnet 552 is powered off, the magnetic repulsive force on the permanent magnet 554 disappears. At this time, the elastic force of the second spring 553 makes the plugging rod 555 retract into the inside of the housing 551.

[0032] At the bottom of the arc-shaped pressing sleeve 1 and corresponding to the position of the adjustable area pressing mechanism 5, there is a circular pressing opening 6. Inside the circular pressing opening 6, a wound temperature detection mechanism 7 is fixedly arranged. The wound temperature detection mechanism 7 includes an elastic silicone pressing sheet 71 fixedly arranged inside the circular pressing opening 6. On the lower surface of the elastic silicone pressing sheet 71, a plurality of uniformly distributed temperature sensors 72 are fixedly embedded. The positions of the plurality of temperature sensors 72 are respectively corresponding to the positions of the circular pressing plate 52 and the plurality of annular pressing plates 53. The plurality of temperature sensors 72 can detect the temperature of the wound and its surrounding area in real time. Based on human physiological characteristics, the temperature at the wound is usually higher than the temperature of the surrounding tissues, so as to judge the size of the wound area according to this detected value.

[0033] At the center of the lower surface of the circular pressing plate 52, a pressure sensor 10 is fixedly embedded. When the circular pressing plate 52 presses the wound, the pressure sensor 10 is in close contact with the elastic silicone pressing sheet 71. At this time, the external force applied by the circular pressing plate 52 to the wound will act on the pressure sensor 10 synchronously, and the pressure sensor 10 can accurately detect the pressing pressure value.

[0034] The drug release mechanism 8 is arranged on the inner side wall of the arc-shaped pressing sleeve 1 and is connected to the adjustable area pressing mechanism 5 for releasing drugs to the wound to promote wound healing and prevent wound infection. The drug release mechanism 8 includes a drug storage box 81 fixedly arranged on the inner side wall of the arc-shaped pressing sleeve 1. Inside the drug storage box 81, drugs for promoting healing (such as recombinant human epidermal growth factor) are stored. At the top of the drug storage box 81, a medicine adding tube 82 is fixedly arranged. When the drugs inside the drug storage box 81 are used up, drugs can be added into the drug storage box 81 through the medicine adding tube 82. Inside the drug storage box 81, a drug pump body 83 is fixedly arranged. The output end of the drug pump body 83 is fixedly provided with a rigid drug delivery tube 84 extending to the outside of the drug storage box 81, and the end of the rigid drug delivery tube 84 adopts a closed structure. On the lower side of the tube wall of the rigid drug delivery tube 84, a plurality of uniformly distributed soft drug branch tubes 85 are fixedly arranged. Due to the characteristics of the soft material, the soft drug branch tubes 85 move along with the circular pressing plate 52 and the plurality of annular pressing plates 53 without affecting the drug delivery. Inside the circular pressing plate 52 and the plurality of annular pressing plates 53, there are drug storage cavities 86 respectively. One end of each of the plurality of soft drug branch tubes 85 far away from the rigid drug delivery tube 84 is fixedly connected to the circular pressing plate 52 and the plurality of annular pressing plates 53 respectively. The tube walls of the plurality of soft drug branch tubes 85 are all provided with electromagnetic switching valves 87. When the drug pump body 83 is started and works, the drugs for promoting healing stored in the drug storage box 81 are sequentially pushed to the rigid drug delivery tube 84 and the soft drug branch tubes 85 that have been conducted, and are respectively injected into the drug storage cavities 86 inside the circular pressing plate 52 and the annular pressing plates 53 through the branch tubes.

[0035] The PLC controller 9 is fixedly arranged on the inner side wall of the arc-shaped pressing sleeve 1. The adjustable area pressing mechanism 5, the wound temperature detection mechanism 7, the drug release mechanism 8, the pressure sensor 10, and the control panel 12 are all electrically connected to the PLC controller 9.

[0036] The operation principle of the present invention is described as follows: When medical staff perform a cardiac pacemaker implantation operation on a patient, if bleeding occurs during the operation, the medical staff need to quickly take the following hemostasis operations. First, suture the wound, and then complete the dressing. After the dressing is completed, use the hemostasis rescue device. Place the arc-shaped pressing sleeve 1 on the patient's chest, ensure that the elastic silicone pressing piece 71 at the upper left position on the arc-shaped pressing sleeve 1 is accurately aligned with the surgical wound on the patient's left chest. Then, wrap the two fixing belts 2 around the patient's back, and achieve the stable fixation of the device through the close fitting of the round felt 3 and the burr felt 4, thus completing the installation of the entire hemostasis rescue device;

[0037] After completing the installation of the hemostasis and rescue device, the medical staff immediately turns on the switch button on the control panel 12 to turn on the power of the device. At this time, since the elastic silicone pressing sheet 71 accurately covers the patient's wound position and multiple temperature sensors 72 are distributed thereon, these temperature sensors 72 can detect the temperature of the wound and its surroundings in real time (during the pressing process, since the elastic silicone pressing sheet 71 has a small deformation degree, resulting in a small displacement of multiple temperature sensors 72, it will not affect the accuracy of wound temperature detection). Based on the physiological characteristics of the human body, the temperature at the wound is usually higher than the temperature of the surrounding tissues (since the wound bleeds very quickly and a large amount of blood flows out of the wound, the bleeding area will show a rapid temperature rise gradient due to blood metabolic activity). The temperature sensor 72 feeds back the detected temperature value to the PLC controller 9. The intelligent analysis system built into the PLC controller 9 quickly analyzes and processes these temperature data, and accurately connects the electromagnetic plug-in mechanisms 55 at different positions through the control circuit. Specifically, the electromagnetic plug-in mechanism 55 above the temperature sensor 72 corresponding to the area with higher temperature value (i.e., the wound position) is preferentially connected, while the electromagnetic plug-in mechanism 55 in the area with lower temperature value (normal tissue around the wound) remains disconnected. When the electromagnetic plug-in mechanism 55 is powered on, current flows through the electromagnetic block 552, and a magnetic repulsion force is generated on the permanent magnet block 554. Under the action of the magnetic repulsion force, the permanent magnet block 554 drives the plug-in rod 555 to overcome the second spring 55. 3 moves outwards until one end of the plug-in rod 555 is accurately inserted into the plug-in ring 556. At this point, the circular pressing plate 52 and the annular pressing plate 53 on its periphery are connected as a whole, and the area of ​​the combination of the two just matches the wound area (the other unconnected annular pressing plates 53 always remain motionless under the elastic force of the elastic telescopic rod 54). Subsequently, the PLC controller 9 sends a start command to the electric push rod 51, and the electric push rod 51 begins to extend, pushing the circular pressing plate 52 and the annular pressing plate 53 connected as one to move downward synchronously. The circular pressing plate 52 and the annular pressing plate 53 need to overcome the elastic force of the elastic telescopic rod 54 during the downward movement. After the circular pressing plate 52 and the annular pressing plate 53 move downward, they will contact the elastic silicone pressing sheet 71 contacts and accurately presses the wound position through the elastic silicone pressing sheet 71. This process realizes the function of adaptively adjusting the pressing area according to the size of the wound, effectively avoiding the problem of too large or too small pressing area. On the one hand, accurate pressing can timely and effectively control wound bleeding, prevent local hematoma, excessive blood loss and other serious complications caused by continuous bleeding, and provide strong protection for the patient's life safety. On the other hand, a suitable pressing area can create a stable healing environment for the wound, reduce unnecessary pressure on surrounding normal tissues, promote blood circulation, accelerate the healing process of the wound, reduce the risk of infection, and improve the patient's postoperative rehabilitation quality and comfort (due to the various shapes of wounds, which may be round, elliptical or polygonal,Multiple temperature sensors 72 are based on the detected temperature value at the outermost edge of the wound to adjust the number of annular pressing plates 53 used, ensuring that the circular pressing plate 52 and the annular pressing plate 53 can completely press the wound after being combined. The whole process realizes automatic pressing, can timely press and stop bleeding for the patient's wound, and improves the efficiency of hemostasis and rescue.

[0038] When the circular pressing plate 52 presses the wound, the pressure sensor 10 is in close contact with the elastic silicone pressing sheet 71. At this time, the external force applied by the circular pressing plate 52 to the wound will act on the pressure sensor 10 synchronously. The pressure sensor 10 can accurately detect the pressing pressure value (the pressure sensor 10 and the temperature sensor 72 below are separated by the elastic silicone pressing sheet 71 and will not affect each other). Subsequently, the pressure sensor 10 quickly feeds back the detected pressure value to the PLC controller 9. After receiving the data, the PLC controller 9 will clearly display it on the display of the control panel 12. Medical staff can observe the pressure value on the display in real time and flexibly control the extension distance of the electric push rod 51 based on their rich clinical experience and close observation of the patient's wound condition, thereby realizing precise adjustment of the pressing pressure on the wound, effectively avoiding local tissue damage caused by excessive pressure on the wound. Excessive pressure will hinder blood circulation around the wound, cause tissue ischemia and hypoxia, delay the wound healing time, and may even cause serious complications such as tissue necrosis. Precise control of pressure can maintain good blood circulation around the wound, provide sufficient nutrition and oxygen for wound healing, and promote cell proliferation and repair. In addition, excessive pressure may cause extrusion or displacement of the cardiac pacemaker and its electrode leads, affecting their normal functions.

[0039] During the process of adjusting the wound's adaptive compression area, the PLC controller 9 accurately controls the electromagnetic switch valve 87 above the circular compression plate 52 and the annular compression plate 53 to open based on the temperature difference detected by the multiple temperature sensors 72, so that the soft drug branch pipe 85 at the corresponding position is turned on. After completing the adaptive adjustment of the compression area, the PLC controller 9 immediately triggers the drug pump body 83 in the drug storage box 81 to start. When the drug pump body 83 is working, the healing-promoting drugs (such as recombinant human epidermal growth factor) stored in the drug storage box 81 are pushed to the hard drug delivery tube 84 and the turned-on soft drug branch pipe 85 in turn, and are respectively injected into the circular compression plate 52 and the annular compression plate 53 through the branch pipes. The drug storage cavity 86 inside the circular pressing plate 53, the circular pressing plate 52 and the annular pressing plate 53 are both made of PLGA (polylactic acid-glycolic acid copolymer) plate. The polylactic acid-glycolic acid copolymer has biocompatible porous hydrophilicity. The recombinant human epidermal growth factor solution in the drug storage cavity 86 can diffuse continuously to the wound surface through the micron-level pore network of the material. This design accurately locates the wound area through temperature feedback, realizes directional delivery and sustained release of drugs, and enables the growth factor to act directly on the key healing site, effectively promotes epithelial cell proliferation and granulation tissue formation, significantly improves the wound healing efficiency, and reduces the amount of drugs and the stimulation to surrounding tissues.

[0040] After the last rescue and hemostasis are completed, the medical staff operates the control panel 12 to stop the electric push rod 51 from working and slowly retract and reset. At the same time, the electromagnetic plug mechanism 55 is powered off, the electromagnetic block 552 loses its magnetism, and the plug rod 555 retracts under the elastic force of the second spring 553. The circular pressing plate 52 is separated from the annular pressing plate 53. The circular pressing plate 52 automatically moves up during the retraction of the electric push rod 51, and the annular pressing plate 53 automatically resets by the elastic force of the elastic telescopic rod 54 on the upper surface. Then, the circular felt 3 and the burr felt 4 of the fixing belt 2 are untied. At the fitting part, gently remove the fixing belt 2 from the patient's back, and then carefully remove the arc-shaped pressing sleeve 1 from the patient's chest to avoid pulling the wound. After removing the device, the medical staff checks the elastic silicone pressing sheet 71 and each component to see if there is any residual medicine or exudate, and classifies and disinfects the used devices. During the disinfection process, the surface dryness of the electrical components is ensured to avoid short circuit of the electrical components and ensure the effect of the next use, especially the multiple exposed temperature sensors 72. The other components are arranged inside the arc-shaped pressing sleeve 1 and will not cause pollution.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
