Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation devices, and particularly to an observable inguinal puncture point restraint system. Background Art

[0002] The inguinal region of the human body is mainly located between the lower abdomen and the thigh. There are abundant nerves, blood vessels and ligaments distributed in the inguinal region. The main artery in the inguinal region is the femoral artery, which is a common puncture point on the body surface for interventional treatment. Interventional surgery through the femoral artery can treat diseases such as tumors, hemangiomas, vascular malformations, and various hemorrhages. When performing femoral artery interventional treatment, the following steps are usually carried out in sequence: finding a suitable puncture point, disinfecting the puncture point and the surrounding skin, anesthetizing the puncture point and the surrounding skin, puncturing with a puncture needle, inserting a guide wire into the femoral artery through the puncture needle and withdrawing the puncture needle, inserting an arterial sheath tube and a sheath core assembly along the guide wire, withdrawing the guide wire and the sheath core after the sheath tube is in place, confirming and flushing the position of the sheath tube, fixing the sheath tube, and stopping bleeding at the puncture point. However, in the above steps, improper fixation of the sheath tube at the puncture point and untimely hemostasis at the puncture point, resulting in complications around the puncture point, are still common problems.

[0003] In the prior art, such as a femoral artery puncture point visible adjustable pressure compression hemostasis device proposed in the invention patent document with the publication number of CN113197612A, which includes a device body and a fixing bandage. The fixing bandage is arranged on the device body, and a visible support frame is fixedly connected to the side wall of the device body. During the compression hemostasis process, the visible support frame can be used for intuitive observation. At the same time, a compression hemostasis mechanism is arranged on the device body, and the compression hemostasis mechanism can achieve the function of hemostasis through compression. In this prior art, although the compression hemostasis process can be simply observed, only a rough side view can be obtained through the visible support frame, and this observation can only be completed manually. Neither medical staff nor even the patient himself can always pay attention to the specific condition of the puncture point. Therefore, in this case, it may be too late to discover other complications such as bleeding and swelling.

[0004] In the prior art, there is a femoral artery puncture point inflatable downward pressure tourniquet proposed in the invention patent document with the publication number CN107970054A, which includes a waist fixing band and an inguinal fixing band. The waist fixing band is horizontally arranged and used to surround and fix at the waist position of the human body. The upper end of the inguinal fixing band is connected to the middle of the waist fixing band, and the lower end of the inguinal fixing band extends obliquely downward. The inguinal fixing band is used to wind and fix at the root of the thigh on the puncture side of the human body. A transparent downward pressure airbag is arranged on the inguinal fixing band at the corresponding femoral artery puncture point of the human body. The transparent downward pressure airbag includes a rigid plate on the outside, a net-shaped elastic layer on the inside, and a transparent airbag wrapped between the rigid plate and the net-shaped elastic layer. Both ends of the rigid plate are respectively connected to the inguinal fixing band, and the periphery of the net-shaped elastic layer is fixedly connected to the periphery of the rigid plate. A pressure gauge is arranged on one side of the transparent airbag.

[0005] In the prior art, there is an adjustable inguinal compression device proposed in the utility model patent document with the publication number CN216363758U, which includes: a trouser body, which is a flat-bottomed trouser; a fixing component, which includes a waistband, a leg fixing band and a connecting band arranged in the middle of the two; a containing component is arranged on the connecting band; the bottom wall of the connecting band is detachably connected to the corresponding compression position of the flat-bottomed trouser; a compression component, which is detachably arranged on the containing component and pressurizes the compression object in the containing component.

[0006] For most of the prior art for fixing and hemostasis at the femoral artery puncture point in the inguinal region, most of them do not consider observing the specific state of the puncture point. For example, the latter two of the aforementioned prior art. And a small part of the prior art even considers the scheme of observing the state of the puncture point, but there is still sufficient room for improvement. For example, the existing observation method can only be observed manually from the side, and both the observation area and the observation situation need to be improved. Secondly, manual observation (including medical staff and the patient himself) cannot always watch the situation of the puncture point, which may lead to untimely discovery of bleeding, swelling or other conditions at the puncture point. And the existing hemostatic compression device cannot perform compression hemostasis at the first time of bleeding. It must be under the premise that the puncture point bleeding is observed manually, and then the hemostatic compression device can be adjusted manually for hemostasis. The timeliness of hemostasis needs to be improved.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, although the inventor studied a large number of documents and patents when making this invention, due to space limitations, all details and contents are not listed in detail. However, this does not mean that this invention does not possess the features of these prior arts. On the contrary, this invention already possesses all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background art. Summary of the Invention

[0008] In view of the deficiencies of the technical solutions proposed in the prior art, the present application proposes an observable inguinal puncture point restraint system, which includes: a collection unit for collecting the status information of the puncture point in real time; an analysis unit for analyzing the status information of the puncture point collected by the collection unit and outputting a result; a control unit for outputting a control signal according to the analysis result of the analysis unit; and a pressing unit for pressing and restraining the puncture point after inguinal intervention surgery.

[0009] The collected image of the patient's puncture site is processed by binarization to achieve the restraint control management of the puncture point after the patient's inguinal intervention surgery with a low-level configuration of computing processing.

[0010] By configuring the above-mentioned various units, it is possible to achieve real-time monitoring of the puncture point and the condition of the skin around the puncture point, and cooperate with each other to take timely hemostasis measures and alarm measures when bleeding or swelling occurs at the puncture point. Among them, the pressing unit can also stably and for a long time fix the sheath in the puncture point to avoid the situation of the sheath tube being dislodged and / or displaced.

[0011] Preferably, the pressing unit has a pressing plate capable of pressing the puncture point and a pressing rod connected to the pressing plate. The end of the pressing rod away from the pressing plate is connected through the surface of the transparent viewing window of the pressing unit. Inside the viewing window, a first collection component capable of collecting the image of the pressing plate and a second collection component capable of collecting the image of the skin around the pressing plate are configured. The analysis unit can receive the image information obtained by the collection unit, perform binarization processing and comparative analysis on the image information, and the control unit can output a control signal based on the analysis result of the analysis unit and regulate the pressure applied by the pressing plate of the pressing unit to the puncture point.

[0012] In the above configuration, the pressing plate can perform compressive hemostasis on the area around the puncture point and has a certain fixing effect on the sheath tube left at the puncture point. The viewing window is transparent, and the puncture point and the skin around it can be clearly observed through the top surface and / or side surface of the viewing window. The collection unit can capture the image information of the puncture point and the skin around it at a certain frequency and send the obtained image information to the analysis unit for analysis. The control unit receives the analysis result of the analysis unit and judges whether to implement corresponding control operations based on the result. The pressing unit can adjust the pressure applied by the pressing plate of the pressing unit to the puncture point through the adjustment component of the pressing unit under the control of the control unit.

[0013] Preferably, the first acquisition component and the second acquisition component of the acquisition unit can respectively acquire the initial images of the pressing plate and the skin around the pressing plate at the first moment when the constraint system is installed at the puncture point. In subsequent times, the first acquisition component and the second acquisition component can acquire corresponding images at a first frequency.

[0014] The initial images are acquired for comparative analysis with the images acquired in subsequent periods, so as to determine whether there are conditions such as bleeding or swelling.

[0015] Preferably, the analysis unit is configured inside a cavity fixedly connected to the visual window of the pressing component. The analysis unit is configured with a first analysis component capable of continuously receiving the images acquired by the first acquisition component and a second analysis component capable of receiving the images acquired by the second acquisition component. The first analysis component and the second analysis component will respectively crop the received images. The first analysis component crops to obtain a first image that only retains the state of the pressing plate, and the second analysis component crops to obtain a second image that only retains the state of the skin, so as to avoid interference between the state of the pressing plate and the state of the skin.

[0016] When the pressing unit is installed, if bleeding occurs at the puncture point, the blood will soak into the pressing plate and change the color of the pressing plate, rather than directly flowing onto the surrounding skin. By separately acquiring and cropping the images of the pressing plate and the skin around the pressing plate, it is possible to respectively judge the bleeding condition and the swelling condition. The cropped images can also reduce the amount of calculation during the analysis and comparison process.

[0017] Preferably, the first analysis component and the second analysis component can perform binary processing on the cropped images.

[0018] Furthermore, the first analysis component can binary-process the initial image of the first image into white. If the puncture point oozes blood and contaminates the pressing plate, the contaminated part of the pressing plate will be binary-processed into black.

[0019] Furthermore, the second analysis component can binary-process the initial image of the second image into white. If the skin around the puncture point shows a swelling state, the swollen skin will be binary-processed into black.

[0020] Furthermore, the analysis unit can perform pixel analysis on the binary images, respectively obtain the number of white pixel points and the number of black pixel points, and calculate the pixel difference between the number of white pixel points and the number of black pixel points.

[0021] According to the above steps, the analysis unit can obtain the pixel difference between the bleeding area or red and swollen area and the non-bleeding area or non-red and swollen area in the image collected by the collection unit at each frequency, and then compare the pixel difference with the pixel difference of the same type in the initial image. If the gap between the two exceeds a preset threshold, there is a risk of bleeding or red and swelling.

[0022] Preferably, the analysis unit compares the difference of the image obtained each time with the difference of the initial image. When the pixel difference between the two first exceeds the set threshold, the following corresponding operations are performed: If the above situation occurs in the first image, the first analysis component will send a suspected bleeding signal to the first collection component. After receiving the suspected bleeding signal, the first collection component will adjust the image collection frequency from the first frequency to the second frequency. If the pixel difference between the first image collected at the second frequency and the pixel difference of the initial image still exceeds the threshold, the first analysis component will send a confirmed bleeding signal to the control unit; If the above situation occurs in the second image, the second analysis component will send a suspected red and swollen signal to the second collection component. After receiving the suspected red and swollen signal, the second collection component will adjust the image collection frequency from the first frequency to the second frequency. If the pixel difference between the second image collected at the second frequency and the pixel difference of the initial image still exceeds the threshold, the second analysis component will send a confirmed red and swollen signal to the control unit.

[0023] In the above configuration, the suspected bleeding signal and / or suspected red and swollen signal fed back by the analysis unit are sent to the collection unit. After receiving the suspected signal, the collection unit can collect the image of the corresponding area at a second frequency faster than the first frequency, so as to speed up the verification step and avoid the untimely initiation of hemostasis measures and warning measures.

[0024] Preferably, the control unit configured inside the top layer of the cavity can obtain the confirmed bleeding signal and / or confirmed red and swollen signal output by the first analysis component and / or the second analysis component.

[0025] Further, when the control unit receives the confirmed bleeding signal, the control unit will drive the adjustment component of the pressing unit to preliminarily adjust the pressure applied to the puncture point to perform temporary hemostasis by increasing the compression force, and the control unit will drive the warning component of the control unit to send a bleeding warning signal.

[0026] Further, when the control unit receives the confirmed red and swollen signal, the control unit will drive the warning component to send a red and swollen warning signal.

[0027] In the above configuration, in case of bleeding at the puncture site, it is necessary to stop the bleeding at the puncture site in a timely manner. Therefore, when receiving the confirmation bleeding signal sent by the first analysis component, the control unit will control the adjustment component to apply pressure to the pressing plate, and at the same time transmit a bleeding warning signal to the warning component. For the swelling condition, no emergency treatment measures are required, so only a swelling warning signal needs to be issued.

[0028] Preferably, the acquisition unit, the analysis unit, and the control unit are all configured on the mechanical structure of the pressing unit. A dressing layer capable of adhering to the skin around the puncture site is provided around the viewing window of the pressing unit. The viewing window includes a fixed window and a movable window that can be movably connected to each other. One end of the pressing rod passing through the surface of the movable window away from the fixed window is connected to a limit block on the outer surface of the movable window to prevent the pressing rod from detaching from the movable window. A movable plate is strung on the inner surface of the movable window on the inner side of the pressing rod, and a spring member is sleeved on the pressing rod between the movable plate and the pressing plate.

[0029] With the above configuration, the dressing layer fixes the viewing window around the puncture site, and the pressing plate just fits on the puncture site to compress and restrain the area around the puncture site and stop the bleeding. Among them, the way of compressing the spring member by using the movable plate compared with the way of directly applying pressure to the pressing plate by pushing the pressing rod, the pressure applied by the spring member has a certain buffering property, while the way of directly pushing and applying pressure does not have buffering property, and the pressure applied will directly act on the pressing plate. Excessive compression may cause additional damage to the wound at the puncture site.

[0030] Preferably, the adjustment component of the pressing unit is inside the cavity. By driving the gear shaft to drive the adjustment column sleeved on the positioning column to rotate, the position of the movable plate can be adjusted steplessly. A slit of the housing through which the adjustment column can pass is configured on the bottom surface of the cavity connected to the movable window. The part of the adjustment column passing through the slit is connected to the movable plate. By using the adjustment column, the distance between the movable plate and the pressing plate can be adjusted, so as to compress the spring member between the two. The pressing unit also sets a manual adjustment component on the side of the driving gear shaft away from the adjustment column.

[0031] Preferably, the sleeving method of the positioning column and the adjustment column of the adjustment component adopts the sleeving method of a screw and a nut. One end of the adjustment column away from the movable window is configured with a gear disk fixedly connected to the adjustment column. The gear disk is driven by a gear shaft arranged inside the cavity. The axial direction of the gear shaft is arranged parallel to the axial direction of the adjustment column.

[0032] The method of driving the adjusting column by a gear can save more length space compared with the method of directly adjusting by a telescopic rod under the premise of meeting the same stroke, so as to facilitate the design of the entire pressing unit to be more compact.

[0033] Preferably, the pressing unit is further configured with a fixing component for holding the pressing unit around the puncture point.

[0034] Furthermore, the fixing component is at least configured with a waist strap that can be wound around the patient's waist. The waist strap is connected to the dressing layer of the pressing unit through a connecting strap. The fixing component is at least further configured with a first leg strap and a second leg strap that can be wound around the patient's legs on the dressing layer. The length of the straps of the fixing component is adjustable, and the surface of the straps that fits the skin has adhesiveness.

[0035] The pressing unit is further fixed by various straps of the fixing component, fully avoiding the situation that the pressing unit falls off or shifts from the puncture point. And the adjustable straps can adapt to patients of different body types, improving the versatility of the restraint system of the present invention. Description of the Drawings

Detailed implementation manners

[0043] The following combines with the attached Figures 1-5 to describe the present invention in detail.

[0044] Figure 1 The figure shows the connection relationship of each unit of an observable inguinal puncture point restraint system of the present invention. The restraint system includes: an acquisition unit 100 for collecting the status information of the puncture point in real time; an analysis unit 200 for analyzing the status information of the puncture point collected by the acquisition unit 100 and outputting a result; a control unit 300 for outputting a control signal according to the analysis result of the analysis unit 200; and a compression unit 400 for compressing and restraining the puncture point after inguinal intervention surgery.

[0045] By configuring the above-mentioned units, it is possible to realize real-time monitoring of the puncture point and the skin condition around the puncture point and cooperate with each other to take timely hemostasis measures and alarm measures when bleeding or swelling occurs at the puncture point. Among them, the compression unit 400 can also stably and for a long time fix the sheath tube in the puncture point to avoid the situation of tube detachment and / or displacement of the sheath tube.

[0046] According to Figures 2-4As shown, the pressing unit 400 has a pressing plate 412 capable of pressing the puncture point and a pressing rod 413 connected to the pressing plate 412. One end of the pressing rod 413 away from the pressing plate 412 penetrates and is connected to the surface of the transparent viewing window 411 of the pressing unit 400. Inside the viewing window 411, a first acquisition component 110 capable of acquiring images at the position of the pressing plate 412 and a second acquisition component 120 capable of acquiring images of the skin around the pressing plate 412 are arranged. The analysis unit 200 can receive the image information obtained by the acquisition unit 100, perform binarization processing and comparative analysis on the image information, and the control unit 300 can output a control signal based on the analysis result of the analysis unit 200 and regulate the pressure applied by the pressing plate 412 of the pressing unit 400 to the puncture point.

[0047] In the above configuration, the pressing plate 412 can perform compressive hemostasis on the area around the puncture point and has a certain fixing effect on the sheath tube left at the puncture point. The viewing window 411 is transparent, and the puncture point and the surrounding skin conditions can be clearly observed through the top surface and / or side surface of the viewing window 411. The acquisition unit 100 can capture the image information of the puncture point and the surrounding skin at a certain frequency and send the acquired image information to the analysis unit 200 for analysis. The control unit 300 receives the analysis result of the analysis unit 200 and determines whether to perform corresponding control operations based on the result. The pressing unit 400 can adjust the pressure applied by the pressing plate 412 of the pressing unit 400 to the puncture point under the control of the control unit 300 through the adjustment component 410 of the pressing unit 400.

[0048] Preferably, the surface of the pressing plate 412 of the pressing unit 400 connected to the pressing rod 413 is set as a shell layer 423, and a contact layer 424 is arranged on the surface of the shell layer 423 in contact with the puncture point. Specifically, the shell layer 423 is also transparent, but the shell layer 423 has a certain hardness, and the contact layer 424 can be connected to the surface of the shell layer 423 using medical cotton.

[0049] Specifically, the geometric center area of the shell layer 423 of the pressing plate 412 protrudes, that is, there is a convex point higher than the surrounding area in the center area of the shell layer 423. The convex point extends smoothly from the surrounding area, and a groove extends from the protrusion to one edge on the shell layer 423. Through the configuration of the protrusion, it is avoided that the pressing plate 412 directly presses the puncture point when pressing the skin around the puncture point, but compressive hemostasis is performed on the surrounding blood vessels through the edge. The groove is to avoid excessive compression of the sheath tube left at the puncture point by the pressing plate 412 and causing its displacement. The groove can both fix the sheath tube and prevent the sheath tube from being directly pressed by the pressing plate 412.

[0050] With the above configuration, the application layer 425 fixes the visual window 411 around the puncture point, and the pressing plate 412 just fits on the puncture point to compress, restrain and stop bleeding at the puncture point. Among them, the method of using the movable plate 414 to compress the spring member 415 has a certain buffering property for the pressure exerted by the spring member 415 compared with the method of directly applying pressure to the pressing plate 412 by pushing the pressure rod 413. The direct pushing and pressurizing method does not have buffering property, and the pressure applied will directly act on the pressing plate 412. Excessive compression may cause additional damage to the wound at the puncture point.

[0051] Specifically, the mechanical structure of the pressing unit 400 is specifically configured such that the pressing unit 400 has a pressing plate 412 capable of pressing the puncture point and a pressure rod 413 connected to the pressing plate 412. One end of the pressure rod 413 away from the pressing plate 412 penetrates and is connected to the surface of the transparent visual window 411 of the pressing unit 400. Through the visual window 411, the pressing condition of the pressing plate 412 on the puncture point can be observed. An adjusting assembly 410 for adjusting the pressure applied by the spring member 415 sleeved on the pressure rod 413 to the pressing plate 412 to the puncture point is arranged on the outer surface of the visual window 411 away from the pressing plate 412. An application layer 425 capable of fitting on the skin around the puncture point is arranged on the circumferential outer side of the visual window 411. Several straps of the fixing assembly 450 are connected to the application layer 425.

[0052] Further, the visual window 411 is divided into a fixed window 428 fixedly connected to the application layer 425 and a movable window 429 detachably connected to the fixed window 428. The fixed window 428 is configured as a cylinder with both ends open, and the movable window 429 is configured as a cylinder with one end connected to the fixed window 428 open.

[0053] Further, the end of the pressure rod 413 where the non-open end of the movable window 429 is not provided is penetrated, and a limit block 427 for preventing the pressure rod 413 from detaching from the movable window 429 is connected to one end of the pressure rod 413 on the outer surface of the movable window 429. A movable movable plate 414 is connected in series on the inner surface of the pressure rod 413 inside the movable window 429. A spring member 415 is sleeved on the pressure rod 413 between the movable plate 414 and the pressing plate 412.

[0054] Further, the adjusting assembly 410 is provided with a cavity 420 fixedly connected to the outer surface of the movable window 429 on the outer surface of the movable window 429, and a positioning column 416 fixedly connected to the top of the cavity 420 through a connecting column is arranged inside the cavity 420.

[0055] Further, the outer surface of the positioning column 416 is provided with threads, and the inside of the positioning column 416 is configured as a hollow area. The end of the pressure rod 413 with the limit block 427 connected to it, which penetrates the movable window 429, is placed in the hollow area of the positioning column 416.

[0056] Further, an adjusting column 417 with a height greater than that of the positioning column 416 is sleeved on the positioning column 416 inside the cavity 420. The inner surface of the adjusting column 417 in threaded contact with the positioning column 416 is provided with nut threads corresponding to the threads of the positioning column 416.

[0057] Furthermore, on the bottom surface of the cavity 420 connected to the movable window 429, there is a slit in the housing that can pass through the adjusting column 417. The part of the adjusting column 417 passing through the slit is connected to the movable plate 414. The distance between the movable plate 414 and the pressing plate 412 can be adjusted by using the adjusting column 417.

[0058] Preferably, the acquisition unit 100, the analysis unit 200, and the control unit 300 are all arranged on the mechanical structure of the pressing unit 400.

[0059] Preferably, the adjusting assembly 410 of the pressing unit 400 is inside the cavity 420. The driving gear shaft 418 drives the adjusting column 417 sleeved on the positioning column 416 to rotate, so as to steplessly adjust the position of the movable plate 414. On the bottom surface of the cavity 420 connected to the movable window 429, there is a slit in the housing that can pass through the adjusting column 417. The part of the adjusting column 417 passing through the slit is connected to the movable plate 414. The distance between the movable plate 414 and the pressing plate 412 can be adjusted by using the adjusting column 417, so as to compress the spring member 415 between the two.

[0060] Preferably, the positioning column 416 of the adjusting assembly 410 and the adjusting column 417 are sleeved in the way of a screw and a nut. A gear disk 419 fixedly connected to the adjusting column 417 is arranged at one end of the adjusting column 417 away from the movable window 429. The gear disk 419 is driven by a gear shaft 418 arranged inside the cavity 420. The axial direction of the gear shaft 418 is parallel to the axial direction of the adjusting column 417.

[0061] Compared with the way of directly using a telescopic rod to adjust, the way of driving the adjusting column 417 to move by a gear can save more length space on the premise of meeting the same stroke, so as to facilitate designing the whole pressing unit 400 to be more compact.

[0062] Preferably, the first acquisition component 110 and the second acquisition component 120 of the acquisition unit 100 can respectively acquire the initial images of the pressing plate 412 and the skin around the pressing plate 412 at the first time when the restraint system is installed at the puncture point. Subsequently, the first acquisition component 110 and the second acquisition component 120 can acquire the corresponding images at the first frequency.

[0063] Specifically, a number of first acquisition components 110 are connected to the surface of the trap door 414 facing the pressing plate 412. Preferably, there are four first acquisition components 110, which are evenly distributed in four directions of the trap door 414. Each first acquisition component 110 can acquire the image information of the pressing plate 412 in the corresponding direction. A number of second acquisition components 120 are connected to the inner surface of the movable window 429 around the trap door 414. Similarly, preferably, there are four second acquisition components 120, which are evenly distributed in four directions around the trap door 414. Each second acquisition component 120 can acquire the image information of the skin in the corresponding direction.

[0064] More specifically, both the first acquisition component 110 and the second acquisition component 120 can be optionally configured as small cameras, such as mobile phone cameras, to avoid occupying too much space.

[0065] The initial image is acquired for comparative analysis with the images acquired in subsequent time periods, so as to determine whether there are conditions such as bleeding or swelling.

[0066] Specifically, the first frequency of the acquisition unit 100 is adjustable, and the specific time of the first frequency can be set. For example, the first frequency can be ten minutes, five minutes, three minutes, one minute, etc. According to the specific situation of the patient, the medical staff can independently select the acquisition frequency.

[0067] Preferably, the images acquired by the acquisition unit 100 can be sent not only to the analysis unit 200, but also to the terminal 500. Specifically, the terminal 500 can be the work computer or mobile phone of the medical staff or an electronic device capable of receiving image information, so as to facilitate the medical staff to quickly view the real-time situation of the puncture site when needed.

[0068] Preferably, the analysis unit 200 is arranged inside the cavity 420 fixedly connected to the visual window 411 of the pressing component. Specifically, the analysis unit 200 is arranged in the half area of the cavity 420 far from the gear shaft 418, and a first partition plate 421 for protecting the analysis unit 200 is arranged between the analysis unit 200 and the adjustment component 410. The first partition plate 421 is placed along the axial lines of the fixed column 416 and the adjustment column 417 of the adjustment component 410, isolating the cavity 420 into two areas.

[0069] Preferably, the analysis unit 200 is configured with a first analysis component 210 capable of continuously receiving the images acquired by the first acquisition component 110 and a second analysis component 220 for receiving the images acquired by the second acquisition component 120. The first analysis component 210 and the second analysis component 220 respectively crop the received images. The first analysis component 210 crops to obtain a first image that only retains the state of the pressing plate 412, and the second analysis component 220 crops to obtain a second image that only retains the state of the skin, thereby avoiding interference between the state of the pressing plate 412 and the state of the skin.

[0070] When the pressing unit 400 is installed and completed, if bleeding occurs at the puncture point, the blood will soak into the inside of the pressing plate 412 and change the color of the pressing plate 412, rather than directly flowing onto the surrounding skin. By separately acquiring and cropping the images of the pressing plate 412 and the skin around the pressing plate 412, it is possible to respectively judge the bleeding situation and the swelling situation, and the cropped images can also reduce the calculation amount during the analysis and comparison process.

[0071] Preferably, the first analysis component 210 and the second analysis component 220 can perform binarization processing on the cropped images.

[0072] Specifically, when performing binarization processing, the analysis unit 200 can use methods such as Matlab or Python to process the images.

[0073] Furthermore, the first analysis component 210 can binarize the initial image of the first image into white. If the puncture point oozes blood and contaminates the pressing plate 412, the contaminated part of the pressing plate 412 will be binarized into black.

[0074] Furthermore, the second analysis component 220 can binarize the initial image of the second image into white. If the skin around the puncture point shows a swelling state, the swollen skin will be binarized into black.

[0075] Furthermore, the analysis unit 200 can perform pixel analysis on the binarized images, respectively obtain the number of white pixel points and the number of black pixel points, and calculate the pixel difference between the number of white pixel points and the number of black pixel points.

[0076] According to the above steps, the analysis unit 200 can obtain the pixel difference between the bleeding area or swelling area and the non-bleeding area or non-swelling area in the images acquired by the acquisition unit 100 at each frequency, and then compare this pixel difference with the pixel difference of the same type in the initial image. If the gap between the two exceeds a pre-set threshold, there is a risk of bleeding or swelling.

[0077] Preferably, the analysis unit 200 compares the difference of each acquired image with the difference of the initial image. When the pixel difference between the two first exceeds the set threshold, the following corresponding operations are performed: If the above situation occurs in the first image, the first analysis component 210 will send a suspected bleeding signal to the first acquisition component 110. After receiving the suspected bleeding signal, the first acquisition component 110 will adjust the image acquisition frequency from the first frequency to the second frequency. If the pixel difference between the first image acquired at the second frequency and the pixel difference of the initial image still exceeds the threshold, the first analysis component 210 will send a confirmed bleeding signal to the control unit 300; If the above situation occurs in the second image, the second analysis component 220 will send a suspected swelling signal to the second acquisition component 120. After receiving the suspected swelling signal, the second acquisition component 120 will adjust the image acquisition frequency from the first frequency to the second frequency. If the pixel difference between the second image acquired at the second frequency and the pixel difference of the initial image still exceeds the threshold, the second analysis component 220 will send a confirmed swelling signal to the control unit 300.

[0078] In the above configuration, the suspected bleeding signal and / or the suspected swelling signal fed back by the analysis unit 200 are sent to the acquisition unit 100. After receiving the suspected signal, the acquisition unit 100 can acquire the image of the corresponding area at a second frequency faster than the first frequency, so as to speed up the verification step and avoid the untimely initiation of hemostasis measures and early warning measures.

[0079] Specifically, the second frequency of the acquisition unit 100 needs to quickly acquire the image. Therefore, the second frequency is preferably set to ten seconds, five seconds, three seconds, etc., so as to quickly confirm the suspected signal and avoid spending too much time verifying the suspected signal.

[0080] Preferably, the control unit 300 configured inside the top layer of the cavity 420 can obtain the confirmed bleeding signal and / or the confirmed swelling signal output by the first analysis component 210 and / or the second analysis component 220.

[0081] Specifically, a second partition 422 is provided at the top of the cavity 420, so as to isolate the positioning post 416 and the adjusting post 417 of the adjusting component 410 and a part of the shaft body of the gear shaft 418 from the control unit 300. A part of the gear shaft 418 penetrates through the second partition 422, and the power component 320 of the control unit 300 configured to drive the gear shaft 418 is connected to the part of the gear shaft 418 extending out of the second partition 422.

[0082] Further, when the control unit 300 receives the confirmed bleeding signal, the power component 320 of the control unit 300 drives the adjustment component 410 of the pressing unit 400 to preliminarily adjust the pressure applied to the puncture point, perform temporary hemostasis by increasing the compression force, and the control unit 300 drives the warning component 310 of the control unit 300 to send a bleeding warning signal. Specifically, as long as the power component 320 is set as a small rotary motor, the control unit 300 controls the power supply connected to the power component 320 to control the rotation state of the motor.

[0083] Further, when the control unit 300 receives the confirmed swelling signal, the control unit 300 drives the warning component 310 to send a swelling warning signal.

[0084] In the above configuration, if bleeding occurs at the puncture point, it is necessary to stop the bleeding at the puncture point in a timely manner. Therefore, when receiving the confirmed bleeding signal sent by the first analysis component 210, the control unit 300 controls the adjustment component 410 to perform a pressurizing operation on the pressing plate 412, and at the same time transmits a bleeding warning signal to the warning component 310. For the swelling condition, no emergency treatment measures are required, so only a swelling warning signal needs to be sent.

[0085] Preferably, after the control unit 300 sends the warning signal, the warning component 310 will give an alarm. The alarm method can be through sound, such as a buzzer, or through light, such as by flashing an indicator light, or a combination of both.

[0086] Preferably, the warning signal of the control unit 300 can also be sent to the terminal 500 of the medical staff. When the signal is sent to the terminal 500 of the medical staff, it can attract the attention of the medical staff through vibration, ringing, etc., so as to transmit the information to the medical staff and promptly handle the abnormal condition of the puncture point.

[0087] Preferably, the pressing unit 400 further sets a manual adjustment component on the side of the driving gear shaft 418 away from the adjustment column 417.

[0088] Specifically, when configuring the initial pressure of the pressing unit 400, the pressure applied to the puncture point by the pressing unit 400 can be adjusted through a manual adjustment component. The manual adjustment component is specifically configured on the right side of the driving gear shaft 418, and its specific shape is also a kind of gear shaft. This gear shaft fixes the manual adjustment component in the cavity 420 through the shaft body. One end of the shaft body extends out of the upper surface of the cavity 420, and a knob for rotating the manual adjustment component is provided at the end extending out of the surface of the cavity 420. A clamping shaft is provided at one end of the knob. The clamping shaft is clamped on the upper surface of the cavity 420 when manual adjustment is not required, and the clamping shaft is rotated into the interior of the cavity 420 when manual adjustment is required. In this way, the gears on the gear shaft of the manual adjustment component can be switched between separation and engagement with the gears of the driving gear shaft. When manual adjustment is required, the two gears are in an engaged state, and when manual adjustment is not required, the two gears are in an upper and lower separated state.

[0089] Preferably, the information transmission between the above-mentioned acquisition unit 100, analysis unit 200, control unit 300, and pressing unit 400 can be a wired connection or a wireless connection.

[0090] According to Figure 5 As shown, the pressing unit 400 is further configured with a fixing component 450 for holding the pressing unit 400 around the puncture point.

[0091] Furthermore, the fixing component 450 is at least configured with a waist strap 451 that can be wound around the patient's waist. The waist strap 451 is connected to the dressing layer 425 of the pressing unit 400 through a connecting strap. The fixing component 450 is at least further configured with a first leg strap 452 and a second leg strap 453 that can be wound around the patient's legs on the dressing layer 425. The lengths of the straps of the fixing component 450 are adjustable, and the surfaces of the straps that fit the skin have adhesiveness.

[0092] Specifically, each strap consists of a strap body, a length adjustment buckle, and a buckle. The two ends of the strap body respectively pass through the length adjustment buckle and the buckle in sequence, and then fold back and are fixed on the length adjustment buckle, so that both ends of the strap form a circular structure. The length adjustment buckle is in the shape of a "day" character. The two ends of the strap body respectively pass through the two end holes of the length adjustment buckle and the buckle in sequence, and then fold back and are fixed on the middle edge of the "day" character-shaped length adjustment buckle. The buckle consists of a "mesh" character-shaped component and a card that can be stuck on the "mesh" character-shaped component. The "mesh" character-shaped component and the card are respectively connected to the two ends of the strap body. By changing the size of the loop formed by the above-mentioned strap, the length of the strap can be adjusted.

[0093] Specifically, the above-mentioned various straps have a certain elasticity, and an adhesion area capable of connecting with its own back in a Velcro manner is arranged at the end of the strap. The back refers to the surface of the strap away from the skin, and its surface is sewn with elastic gauze, and a pressure-sensitive adhesive is applied on the elastic gauze layer to further fix the pressing component.

[0094] Preferably, a fixing strip 426 capable of fixing the sheath tube indwelling at the puncture site is further arranged in the application layer 425 of the pressing unit 400. The adhesiveness of the fixing strip 426 is higher than that of the application layer 425. However, since too high adhesiveness is not conducive to tearing off from the skin, or too high adhesiveness is likely to cause greater pain to the patient when tearing off, only a fixing strip 426 with a smaller area is used to fix at the three-way interface of the sheath tube.

[0095] The pressing unit 400 is further fixed by various straps of the fixing component 450, which fully avoids the situation that the pressing unit 400 falls off or shifts from the puncture site, and the adjustable straps can adapt to patients with different body types, improving the versatility of the restraint system of the present invention.

[0096] According to a preferred embodiment, this embodiment provides a device that can quickly and real-time obtain an image of the puncture site near the puncture position of the patient, and can quickly judge various exudation situations and make corresponding prevention plans. The structure of this embodiment is generally the same as that of the above-mentioned embodiment. The improvement lies in that the part of the pressing unit 400 in this embodiment that applies pressure to the physiological part of the patient, that is, the pressing plate 412 and its moving participating part, are configured as differentiated regions and can be separately controlled to apply or relieve pressure to the expected target position. For example, when the pressing plate 412 is configured as a ring, at least two of its regions are differentially divided, for example, the two parts are directly separated physically to form two semi-circular rings or a combination of a partial ring and another partial ring, and the two rings complement each other and can jointly form the ring structure of the entire pressing plate 412.

[0097] Furthermore, the pressing plate 412 is not only divided into two independent regions, but can also be divided into more regions in the case of more pressing requirements.

[0098] Preferably, in this embodiment, the pressing plate 412 is at least divided into a penetration pressing area, a puncture needle pressing area, and a redundant pressing area. When the device is in use, the three pressing areas are respectively used to press the liquid seepage point, the puncture needle, and the remaining parts. At this time, the division of the three pressing areas is based on their functions. Specifically, the pressing plate 412 itself can be divided into several independent pressing areas, each of which can be called a pressing unit 400 area. When a certain or several pressing unit 400 areas are used to press a certain object (such as a liquid seepage point), the one or several pressing unit 400 areas constitute the corresponding pressing area.

[0099] For the pressing requirements for different targets, different pressing areas can be configured to have different functions and even structures. Specifically, the puncture needle pressing area is configured as a pressing structure containing at least a medical film, the liquid seepage point pressing area is configured as a pressing structure containing at least a variety of switchable disinfection and dressings, and the redundant pressing area is configured as a pressing structure with at least a liquid absorption detection unit combined with a bypass pressing unit 400 and being switchable.

[0100] The above-mentioned switchable structure can utilize, for example, dividing different sub-areas within the same pressing area. Each sub-area has an independently adjustable pressing structure and is coated with a dressing or configured with a cloth structure coated with the corresponding dressing. When needed, a certain or several sub-areas can be individually controlled to press against the patient's body. Further, it is at least divided into three sub-areas. One is a single gauze dressing sub-area, the second is a dressing sub-area containing a blood coagulation component, and the third is a dressing sub-area containing silver ion alginate. Among them, the blood coagulation component can be a substance capable of coagulating blood, such as gelatin sponge, aminocaproic acid, etc. The sub-areas can be arranged in a concentrically expanding manner along the radial direction of the pressing plate 412 so that each sub-area can apply pressure to as many patient body areas as possible. Preferably, the silver ion alginate area also has a liquid absorption detection unit.

[0101] Based on the above, this embodiment provides an automatic detection and pressing scheme.

[0102] During normal time, a single gauze dressing sub-region is pressed against the puncture site of the patient, and the acquisition unit 100 acquires the surface of the single gauze dressing corresponding to the puncture wound site. When a liquid leakage point is detected by visual recognition, the analysis unit 200 confirms the position of the first liquid leakage point and first controls the single gauze dressing sub-region to increase pressure and simultaneously controls the injection needle pressing area to increase pressure. During this process, the acquisition unit 100 continuously acquires the diffusion image of the liquid leakage on the surface of the single gauze dressing at the second frequency. The analysis unit 200 analyzes the change ratio of the proportion of the black color level in the white color level on the surface of the single gauze dressing in the diffusion image based on video frames. When the change ratio is lower than the first threshold, the current operation is maintained until the analysis unit 200 confirms through the acquired image that the liquid leakage has stopped. When the change ratio is higher than the first threshold and lower than the second threshold, the control unit 300 controls the injection needle pressing area to reduce pressure, and the analysis unit 200 continues to analyze the acquired image simultaneously. If the change ratio changes to a continuous decrease and can change to be lower than the first threshold, the current reduced pressure of the injection needle pressing area and the pressure of the single gauze sub-region are maintained for continuous compression until it is determined that the liquid leakage has stopped. If the change ratio still maintains the current level or continues to increase, the control unit 300 controls the injection needle pressing area to increase pressure and switches the single gauze dressing sub-region to a dressing sub-region containing coagulation components, and continues to maintain compression until it is detected that the liquid leakage has stopped.

[0103] This solution is based on the full-automatic detection of the patient's puncture site. Compared with traditional manual care, it can detect bleeding at the first time and, based on the rapid detection of the bleeding rate, can change the compression mode and re-check the effect simultaneously in the same period, so as to quickly find the most suitable compression plan for the current liquid leakage situation. For example, this solution notes that in addition to changes in the pressure at the puncture site or changes in blood vessel gaps, the cause of liquid leakage may also be related to the pressure of the injection needle. Moreover, too much pressure on the injection needle may cause liquid leakage due to compression at the puncture point, and too little pressure on the injection needle may also cause liquid leakage due to gaps in blood vessels. Therefore, the light or heavy pressure state of the injection needle is also an object that needs to be considered urgently. In the traditional manual care mode, it is impossible to respond quickly to liquid leakage and quickly adjust the compression method using the liquid leakage situation in a short time. Often, when liquid leakage is found, the liquid has completely or mostly contaminated the gauze, neither knowing the position of the liquid leakage point nor the rate of liquid leakage, and even more unable to accurately adjust the compression mode based on this, resulting in slow and inadequate treatment of liquid leakage and even causing a worsening effect. However, this solution can quickly confirm the liquid leakage point and the best compression plan using this short golden time of liquid leakage, can adjust the compression method for the injection needle part, quickly judge and adjust the final compression method using the liquid leakage situation, can significantly improve the expected benefit of this step, and improve the safety of the patient's puncture. Here, the injection needle can be understood as the part that pierces the patient's body, such as an injection needle or a indwelling catheter.

[0104] Additionally, when the liquid absorption detection unit detects a liquid leakage point, the control unit 300 controls the silver ion alginate sub-region and / or the bypass pressing region to press their corresponding regions singly or jointly. In one case, the pressing region corresponding to the liquid absorption detection unit that detects the corresponding signal operates. In one case, when any liquid absorption detection unit generates a detection signal, the two above-mentioned pressing regions both operate. This solution enables the device to not only handle blood leakage but also specifically handle the situation of lymph fluid leakage. Since lymph fluid is usually colorless and it is relatively difficult to judge by image recognition, therefore, by configuring the liquid absorption detection method to obtain the lymph fluid penetration situation, targeted compression prevention measures can be achieved. The bypass pressing region mainly presses the lymphatic vessels running parallel to the blood vessels, and compared with directly pressing the puncture region of the blood vessel usually, the pressing effect on this bypass part is better.
