[0001] The present invention relates to the technical field of medical devices, and in particular to a wound area measurement auxiliary device. Background Art

[0002] Clinically, for patients who have wound dressing changes, wound area measurement and wound image acquisition are required before each dressing change to provide an objective basis for assessing wound severity, selecting wound treatment plans, and monitoring wound healing. However, the traditional wound measurement method is to use a wound ruler, and the traditional wound image acquisition method is to use a mobile phone or PDA to take handheld photos. However, these methods have certain disadvantages.

[0003] The traditional measurement method is to use a wound ruler, which will inevitably touch the wound bed. This contact measurement will increase the risk of wound infection. Figure 1 As shown in the figure, the measurement method is to first measure the length L of the longest axis, and then measure the widest width W in the vertical direction. The wound area is L×W. Obviously, the wound area obtained by this measurement method is inaccurate. In addition, affected by factors such as measurement distance, angle, and light, there are differences in the wound images collected by different medical staff. The wound image will affect the observation of the wound area and even the local condition of the wound, making it difficult for medical staff to make longitudinal comparisons of the wound conditions of the same patient at different times.

[0037] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0038] Embodiment 1:

[0039] An embodiment of the present invention provides a wound area measurement auxiliary device, such as Figure 2 As shown, including:

[0040] Bracket 201;

[0041] A grid projection lamp 202 is disposed on the bracket 201 and is used to emit a grid-shaped projection and illuminate the patient's wound;

[0042] The terminal device 203 is clamped on the bracket 201, and includes: an image acquisition module, which is used to acquire the patient's wound image, and the wound image has a grid projection; a wound management module, which is used to determine the wound area based on the wound image, and determine the recovery of the wound based on the wound area at different periods.

[0043] The terminal device 203 may be a mobile phone or a PDA, which have image acquisition functions, and the wound management module may be implemented through software.

[0044] The support 201 is described in detail below. The support 201 includes: a hydraulic adjustment arm for adjusting a support angle; and a base with universal wheels disposed below the base.

[0045] In a specific implementation, by adjusting the support angle of the hydraulic adjustment arm, the terminal device 203 clamped on the bracket 201 can take pictures of wounds at different parts of the same patient. The universal wheels under the base can support the flexible movement of the bracket 201, and specifically, three universal wheels or more universal wheels can be set.

[0046] Before medical staff change the dressing on the patient's wound, they can place the bracket 201 according to the position of the wound. If there are multiple wounds, they can control the universal wheels by foot to move to the position of the next wound and continue to change the dressing. This will not damage the sterile area and can continuously change the dressings on multiple wounds of the same patient, saving time and effort.

[0047] The bracket 201 is also provided with a clamp for clamping the terminal device 203. The clamp can be clamped on both sides of the terminal device 203 to ensure stability when collecting wound images.

[0048] The support 201 also includes:

[0049] Voice collection module, used to receive voice control instructions from medical staff;

[0050] The Bluetooth module is used to connect the image acquisition module and the voice acquisition module. After the voice acquisition module acquires the voice control instruction, it is transmitted to the image acquisition module through the Bluetooth module to control the acquisition of the image acquisition module.

[0051] The image acquisition module can be controlled by voice to shoot and other controls. This can free the hands of medical staff and achieve flexible control.

[0052] In another embodiment, the support 201 includes:

[0053] Operation buttons: used to receive key operations from medical staff;

[0054] The Bluetooth module connects the image acquisition module and the operation case. When the operation button receives the operation of the medical staff, it is transmitted to the image acquisition module through the Bluetooth module to realize the acquisition control of the image acquisition module.

[0055] The operation button can be held in the hands of medical staff or hung on a bracket for easy access by medical staff.

[0056] In an optional embodiment, the grid projection lamp 202 in the wound area measurement auxiliary device is fixedly set on the bracket 201, specifically, it is set at the top of the clamp, which is consistent with the position of the terminal device 203, so that when the target is photographed, the grid-shaped projection of the grid projection lamp 202 can be correspondingly irradiated onto the target.

[0057] The projection image of the grid projection lamp 102 is as follows Figure 3 As shown. The size of each grid is fixed, for example, it can be 1 cm × 1 cm. Of course, it can also be other sizes. The smaller the size, the more accurate the calculated wound area. There is no limitation on the size of a single grid.

[0058] The grid projection lamp 102 comprises:

[0059] light source;

[0060] Distance measurement module, used to measure the distance between the light source and the projection target;

[0061] A determination module is used to determine the size of a single grid of the grid-like projection based on the distance.

[0062] If the distance between the light source and the projection target is 50cm, the size of a single grid of the grid projection is determined to be 1cm×1cm. When the distance between the light source and the projection target is greater than 50cm, the size of a single grid will be slightly larger than 1cm×1cm. When the distance is less than 50cm, the size of a single grid will be slightly smaller than 1cm×1cm.

[0063] The size corresponding to the distance of 50cm is a standard setting and is not limited here. When the distance increases by 1cm, the corresponding single grid increases the preset size, which is determined by the actual situation and is not limited in this application. In a specific usage scenario, the distance of 50cm is a common setting, so the size of the corresponding single grid is also used according to the size of 1cm×1cm.

[0064] After the grid projection lamp 102 irradiates the patient's wound, the image acquisition module of the terminal device 203 acquires the wound image to obtain the wound image with a grid projection.

[0065] In order to improve the recovery of wounds, the light source of the grid projection lamp 102 uses infrared light, which has the functions of improving blood circulation, reducing inflammatory response, promoting tissue repair and regeneration, relieving pain, etc., and has the dual functions of measurement and treatment.

[0066] Next, the wound management module analyzes the wound image to determine the area of ​​the wound.

[0067] Specifically, the wound management module is used to calculate the number of grids of the grid projection at the wound based on the wound image; and determine the wound area based on the number of grids of the grid projection.

[0068] When calculating the number of grids of the grid projection at the wound, specifically, the number of grids in the overlapping area between the wound edge and the grid projection is calculated.

[0069] The wound management module is also used to calculate the wound area at the edge of the grid-shaped projection of the wound by mutual filling.

[0070] Specifically, for the area where the grid projection completely overlaps with the wound, the number of grids is directly counted; because the edge of the wound and the edge of the grid projection do not completely overlap, the number of grids can be roughly estimated. For grids that only overlap half of the area, they can be merged with grids that also overlap half of the area to obtain the area of ​​a grid. For grids that overlap less than half of the area or more than half of the area, the area of ​​a single grid is formed by patchwork. For grids that are not successfully patched together, their areas are determined based on the ratio of the area of ​​the entire grid.

[0071] In an optional implementation, the wound management module is further used to: assign different marking information based on wounds in different locations, so as to be used for marking wound images collected at different periods.

[0072] The mark information can be specifically marked according to the identification of the body part, so that when the mark information is seen, the location of the wound can be roughly determined. At the same time, by allocating the mark information, the wound pictures collected at different times can be classified and stored, and sorted according to the markings of different periods.

[0073] For example, wounds on the hand are marked with H, wounds on the face are marked with F, and so on. Numbers are marked after the letters according to different parts of the body, specifically in order from the inside to the outside.

[0074] Next, the corresponding wound area is determined based on the actual wound images collected, and then the recovery of the wound is determined based on the wound areas at different periods.

[0075] During the wound recovery process, if the recovery is good, the wound area will become smaller and smaller over time; if the wound recovery is poor, the wound area will remain unchanged for a long time or tend to increase over time. Therefore, the wound management module is also used to adjust the wound treatment plan based on the wound recovery condition.

[0076] If the wound recovers well, the wound treatment plan can be adjusted by reducing medications, etc. If the wound recovers poorly, it is necessary to change medications or adjust the wound treatment plan by other means.

[0077] Accurate determination of the wound area can provide an effective basis for subsequent treatment.

Through the grid-shaped projection, the overlapping area of ​​the wound and the grid-shaped projection can be determined, and the wound area can be determined by calculating the number of grids in the overlapping area, thereby improving the accuracy of wound area measurement and reducing the risk of wound infection.

[0080] The wound area measurement auxiliary device can avoid the tedious traditional operation process and realize wound image acquisition through voice control. It neither affects the dressing change operation nor destroys the sterile environment. It is convenient and fast.
