Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a regional hemostatic patch and device. Background Technology

[0002] Traditional hemostasis methods mostly employ mechanical compression and suturing, which are complex, time-consuming, and labor-intensive, with significant limitations. Especially when dealing with large areas of oozing or complex wounds, problems such as tissue adhesion and eschar formation can easily occur, leading to poor hemostasis. To address this, a series of hemostatic devices have been developed that utilize specific technologies (such as high-frequency current and ultrasonic energy) to achieve rapid hemostasis at the bleeding point.

[0003] Current hemostatic devices are mostly single-point hemostasis devices, which are cumbersome and require high standards of operation. They can only perform linear hemostasis within the same unit of time and cannot perform area hemostasis, resulting in low efficiency. At the same time, they also have poor adhesion to the wound surface, resulting in poor temperature control of the area. If the temperature is too high, it may cause excessive tissue damage, while if the temperature is too low, it may not be able to stop the bleeding effectively, resulting in poor hemostatic effect.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content

[0005] The purpose of this application is to provide a regional hemostatic patch and device that can fit closely to the wound surface, achieve precise control of the hemostatic temperature in different areas of the wound, and thus use segmented heating technology to achieve regional hemostasis, which is fast and effective.

[0006] The technical solution provided by this utility model is as follows:

[0007] A regional hemostasis device, comprising:

[0008] A regional hemostatic patch includes a patch body and a heating medium embedded in the patch body, wherein the patch body has an application side suitable for application to a wound surface;

[0009] An electric heating control device, electrically connected to the hemostatic patch in the area, includes a thermal field analysis module, a data processing module, and an energy output module. The thermal field analysis module performs thermal field analysis on the application side of the patch body to obtain temperature changes at different locations on the application side. The data processing module obtains preset target temperature values ​​at different locations on the application side and controls the energy output of the energy output module through a built-in control algorithm. The energy output module outputs energy to the heating medium to heat the heating medium, thereby controlling the temperature at different locations on the application side.

[0010] In some embodiments, the regional hemostatic patch further includes a temperature sensor embedded in the patch body for detecting the temperature of the applied side;

[0011] The electric heating control device also includes a temperature acquisition module, which includes multiple temperature measurement nodes for acquiring the temperature detected by the temperature sensor and transmitting the acquired temperature data to the data processing module.

[0012] The data processing module is configured to acquire the temperature data and transmit the temperature data to the thermal field analysis module, so that the thermal field analysis module can perform thermal field analysis on the bonding side of the patch body.

[0013] In some embodiments, the electric heating control device further includes an over-temperature protection module, which cuts off the operating circuit of the energy output module when the temperature detected by the temperature sensor exceeds a preset first threshold.

[0014] In some embodiments, the energy output module includes an energy source and a detection module. The energy source is configured to output energy under the control of the data function processing module. The detection module is used to detect the actual energy output of the energy source and compare the actual energy output with the controlled energy output of the data function processing module. When the difference between the actual energy output and the controlled energy output exceeds a preset second threshold, the energy source is turned off.

[0015] In some embodiments, the electric heating control device further includes a parameter configuration module for setting the target temperature value and the first threshold.

[0016] In some embodiments, the electric heating control device further includes a consumable detection module for detecting the impedance characteristics of the regional hemostatic patch to evaluate the quality of the regional hemostatic patch.

[0017] In some embodiments, the electric heating control device further includes a visualization interface for displaying the thermal map output by the thermal field analysis module and the operating parameters of the electric heating control device.

[0018] This application also provides a regional hemostasis patch, applicable to the regional hemostasis device provided in any of the above embodiments, comprising:

[0019] The patch body and the heating medium embedded in the patch body;

[0020] The patch body has an application side suitable for application to a wound, and the heating medium is used to heat the application side to perform thermal coagulation and hemostasis on the wound.

[0021] The patch body is made of a flexible thermally conductive material, and at least one side of the patch body facing away from the patch side is made of a flexible thermally insulating material.

[0022] In some embodiments, a cable is externally connected to the side of the patch body opposite to the application side, and the cable is electrically connected to the heating medium and the electric heating control device;

[0023] and / or

[0024] The patch body has a clamping strip on the side opposite to the application side.

[0025] The technical advantages of this application are as follows:

[0026] 1. In this application, by setting regional hemostatic patches, it is possible to better fit the wound surface. At the same time, combined with temperature control technology, it is beneficial to achieve precise control of the hemostatic temperature in each area of ​​the wound surface. This allows for the output of higher hemostatic temperatures to the capillary bleeding points to achieve rapid hemostasis, while the remaining areas use conventional hemostatic temperatures to prevent local overheating and tissue carbonization. This results in better hemostatic effect and regional hemostasis.

[0027] 2. In this application, by setting a temperature acquisition module, the temperature sensor in the regional hemostatic patch can be acquired in real time with high precision. The temperature acquisition module includes multiple temperature measurement nodes. Through the redundancy of multiple temperature measurement nodes, the risk of reduced hemostatic performance due to abnormal temperature measurement can be effectively prevented, resulting in better hemostatic effect and better fault tolerance.

[0028] 3. In this application, the electric heating control device is equipped with an over-temperature protection module and a detection module, which can promptly cut off the energy output when the temperature is too high or the energy output is unstable, ensuring high safety and preventing tissue carbonization caused by excessively high local hemostasis temperature. Simultaneously, the detection module improves the consistency between actual energy output and controlled energy output, ensuring the effectiveness of energy output. Attached Figure Description

[0036] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details.

Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0038] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0039] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0040] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Most current hemostatic devices are single-point hemostasis devices, which can only perform linear hemostasis within the same unit of time and cannot perform regional surface hemostasis. At the same time, they also have poor adhesion to the wound surface, resulting in poor temperature control in the area and poor hemostatic effect.

[0044] For this, see Figure 1 and Figure 3 This application provides a regional hemostasis device, including a regional hemostasis patch 100 and an electric heating control device, which are connected by wired or wireless means. The regional hemostasis patch 100 is a disposable consumable that can be applied to the wound and adhere tightly to the entire wound surface. Combined with the electric heating control device, temperature control technology is used to precisely control the temperature at various points on the regional hemostasis patch 100, achieving rapid regional hemostasis. It can be used for both point wounds and surface wounds, offering strong practicality and superior hemostatic effect.

[0045] Specifically, see Figure 3 and Figure 4 The regional hemostatic patch 100 is a flexible patch, including a patch body 110 and a heating medium 120 embedded in the patch body 110. The patch body 110 has an application side 111, which can fit tightly to the entire wound surface. The heating medium 120 can be heated under the action of an electric heating control device and provide heat to the wound area.

[0046] The electric heating control device includes a thermal field analysis module, a data function processing module, and an energy output module. The thermal field analysis module is used to perform thermal field analysis on the application side 111 of the patch body 110 to obtain the temperature changes at different positions on the application side 111 of the patch body 110. The data function processing module is used to obtain the preset target temperature values ​​at different positions on the application side 111 and control the energy output of the energy output module through the built-in control algorithm. The energy output module is used to output energy to the heating medium 120 to heat the heating medium 120, thereby controlling the temperature at different positions on the application side 111.

[0047] In this embodiment, a thermal field analysis module is used to perform thermal field analysis on the dressing side 111, which can correspondingly obtain the current temperature values ​​at different locations on the entire wound surface, helping to determine the bleeding points. For bleeding points, i.e., capillary oozing points, a higher preset target temperature value is set to achieve rapid hemostasis; for other wound areas, a conventional hemostasis temperature is set as the preset target temperature value to avoid tissue carbonization due to local overheating, ensuring high safety. The data processing module controls the energy output module to output energy until the temperature at different locations on the dressing side 111 reaches the preset target temperature value. During this process, the thermal field analysis module performs thermal field analysis on the dressing side 111, which can quickly and effectively reflect the temperature changes at different locations on the wound surface during hemostasis, facilitating real-time monitoring and further improving the safety of the regional hemostasis device.

[0048] Specifically, the regional hemostatic patch 100 also includes a temperature sensor embedded in the patch body 110. The temperature sensor is used to detect the temperature of the application side 111, thereby obtaining the temperature of the entire wound surface and providing a data basis for the thermal field analysis of the thermal field analysis module. Multiple temperature sensors are used to form a temperature sensor matrix, enabling block-based temperature measurement and thus obtaining the temperature at different locations within the entire wound area.

[0049] Conversely, the electric heating control device also includes a temperature acquisition module, which comprises multiple temperature measurement nodes for acquiring the temperature detected by the temperature sensor and transmitting the acquired temperature data to the data processing module. The data processing module is configured to acquire temperature data and transmit the temperature data to the thermal field analysis module, which performs thermal field analysis on the bonding side 111 of the patch body 110.

[0050] In this embodiment, the temperature acquisition module preferably employs a high-precision temperature detection circuit, capable of real-time, high-precision temperature acquisition from the temperature sensor matrix within the regional hemostasis patch 100. For example, the temperature acquisition interval is 0.1 seconds, and the measurement accuracy is ±0.1℃. Furthermore, because the temperature acquisition module in this embodiment includes multiple temperature measurement nodes, the redundancy of these nodes prevents the risk of reduced hemostasis performance due to abnormal temperature readings. This provides good fault tolerance, ensuring that the regional hemostasis device can cope with various complex and unpredictable environments and maintain stable operation.

[0051] Further, see Figure 1 and Figure 2The electric heating control device also includes an over-temperature protection module. When the temperature detected by the temperature sensor exceeds a preset first threshold, the over-temperature protection module cuts off the operating circuit of the energy output module, ensuring high safety and effectively preventing tissue carbonization caused by excessively high local hemostasis temperature. Preferably, the over-temperature protection module also has an alarm function; when it cuts off the operating circuit of the energy output module, it will simultaneously emit an alarm sound to alert medical personnel.

[0052] In actual production, the over-temperature protection module can either directly cut off the operating circuit of the energy output module, or first send a cut-off signal command to the data function processing module, which then controls the energy output module to stop energy output. The first threshold can be a clinically safe temperature limit, or it can be adaptively adjusted through temperature parameter configuration. However, to ensure the safety of the entire area's hemostasis device, there is a maximum over-temperature limit when adaptively adjusting; therefore, the first threshold must be set within this limit.

[0053] In one specific embodiment, the energy output module includes an energy source and a detection module. The energy source is configured to output energy under the control of the data function processing module. The detection module detects the actual energy output of the energy source and compares the actual energy output with the control energy output of the data function processing module (i.e., the control variable driving the energy source output by the data function processing module through a control algorithm after receiving a preset target temperature value). When the difference between the actual energy output and the control energy output exceeds a preset second threshold, the energy source is turned off.

[0054] Preferably, the energy output module also includes an abnormality alarm module. When the difference between the actual energy output and the controlled energy output exceeds a preset second threshold, the energy is turned off, and the abnormality alarm module sounds an alarm to notify medical staff of the abnormality.

[0055] Specifically, the electric heating control device also includes a parameter configuration module for setting preset target temperature values ​​at different locations on the application side 111 of the regional hemostatic patch 100. These parameter values ​​can be defined based on thermal field analysis of the wound area or the current actual temperature value. Furthermore, to ensure the safety and effectiveness of the hemostasis process, there are limitations on misuse when configuring the preset target temperature values. For example, a range for the preset target temperature values ​​is set to prevent medical personnel from accidentally entering incorrect parameters.

[0056] Furthermore, the parameter configuration module can also be used by medical staff to set the specific values ​​of the first and second thresholds mentioned above, so as to improve the safety protection performance of the regional hemostasis device.

[0057] Specifically, the electric heating control device also includes a consumable testing module, which is used to test the impedance characteristics of the regional hemostasis patch 100 in order to evaluate the quality of the regional hemostasis patch 100, such as the compliance and effectiveness of the regional hemostasis patch 100, and ensure the normal use of the regional hemostasis patch 100.

[0058] Specifically, the electric heating control device also includes a visualization interface for displaying the thermal map output by the thermal field analysis module and the operating parameters of the electric heating control device. The operating parameters include at least the parameters configured in the parameter configuration module. The display of other key parameters can be flexibly set based on the actual situation, and will not be elaborated here, but are all within the protection scope of this application.

[0059] In the above embodiments, the data function processing module serves as the main function control module and can be used for data management and function processing in system configuration, function control, security protection, consumable testing, and process testing.

[0060] See Figure 1 , Figure 3 and Figure 4 This application also provides a regional hemostatic patch 100, namely, the regional hemostatic patch 100 in the regional hemostatic device provided in any of the above embodiments. Specifically, the regional hemostatic patch 100 includes a patch body 110 and a heating medium 120 embedded in the patch body 110. The patch body 110 has an application side 111, which is suitable for application to a wound. The heating medium 120 is used to heat the application side 111 to perform thermal coagulation hemostasis on the wound. The application side 111 is made of a flexible thermally conductive material, and at least one side of the patch body 110 facing away from the application side 111 is made of a flexible thermally insulating material.

[0061] In this embodiment, the regional hemostatic patch 100 is generally flexible, which is more conducive to achieving close adhesion to the wound. At the same time, the application side 111 of the patch body 110 is made of thermally conductive material, which can effectively transfer the heat of the heating medium 120 to the wound, resulting in good hemostasis. It also allows medical staff to obtain the temperature of the wound by measuring the temperature of the application side 111, making it highly practical. The rest of the patch body 110, especially the side of the patch body 110 facing away from the application side 111, is made of heat-insulating material, which can effectively prevent medical staff or other personnel from being burned by accidentally touching the patch body 110.

[0062] Specifically, see Figure 3 and Figure 4A cable 130 is connected to the side of the patch body 110 away from the application side 111. The cable 130 is electrically connected to the heating medium 120 and the electric heating control device so that the electric heating control device can output energy to heat the heating medium 120, thereby accurately controlling the temperature at different positions of the application side 111, and outputting the corresponding hemostatic temperature for different positions of the wound area, resulting in better hemostatic effect.

[0063] Preferably, the patch body 110 has an interface 112 on the side opposite to the application side 111. The patch body 110 can be plugged into and detached from the cable 130 through the interface 112, which makes it convenient for medical staff to replace the regional hemostatic patch 100. The structure is more reasonable and effective.

[0064] Specifically, the patch body 110 also has a clamping strip 113 on the side opposite to the application side 111. The clamping strip 113 can be adjusted in shape according to different body parts to ensure that the patch body 110 can fit tightly to the wound. In addition, the clamping strip 113 can also be used to dock with external structures, providing additional physical support for the patch body 110 to reduce pressure on the wound skin and prevent damage. There are two clamping strips 113, and the two clamping strips 113 are spaced apart on the side of the patch body 110 opposite to the application side 111.

[0065] Of course, in actual production, the mounting tape 113 can also be used in conjunction with electric heating control equipment to achieve remote monitoring and data transmission. For example, multiple temperature sensors can be integrated into the mounting tape 113, forming a temperature sensor matrix. In this case, there is no need to embed temperature sensors inside the patch body 110. The electric heating control equipment can directly obtain real-time temperature data through the mounting tape 113. Further details are omitted here, as they are all within the scope of protection of this application.

[0066] See Figure 2This application also provides a regional hemostasis method, applicable to the regional hemostasis device provided in any of the above embodiments, and includes the following steps: First, the electric heating control device is turned on. After being turned on, the electric heating control device performs a self-test, and then detects the impedance of the regional hemostasis patch 100 to confirm whether the quality of the regional hemostasis patch 100 meets the standard. If the regional hemostasis patch 100 meets the standard, the subsequent steps are performed; otherwise, the regional hemostasis patch 100 is replaced until it meets the standard. After confirming that the quality of the regional hemostasis patch 100 meets the standard, the regional hemostasis patch 100 is applied to the wound. Subsequently, the thermal field analysis module performs thermal field analysis on the application side 111 of the patch body 110 and outputs a thermal image. Based on the thermal image or the actual temperature value of the wound area, medical personnel set preset target temperature values ​​for different positions on the application side 111. Furthermore, during the setup process, due to the possibility of misuse, the data processing module will first determine whether the parameter configuration is normal. If it is abnormal, it will prompt medical staff to reset it; if it is normal, the data processing module will control the energy output module to output energy to the heating medium 120. Conversely, during the energy output control process, the over-temperature protection module and the detection module will monitor the operating temperature and energy output of the electric heating control device in real time. Once the temperature is too high or the energy output is unstable, the energy source output will be cut off and an alarm will be triggered to ensure the safety and effectiveness of the regional hemostasis device. Of course, if there are no abnormalities in the entire process, the energy source will continue to output energy under the control of the data processing module until the temperature of the patch side 111 reaches the preset target temperature value, at which point the electric heating control device will stop, completing thermal coagulation hemostasis.

[0067] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
