[0039] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0040] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0041] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0042] See also Figure 1-Figure 3 , a local oxygen therapy device in an embodiment of the present invention comprises: a binding strap; a first connecting piece is provided on one side of the binding strap, and a second connecting piece is provided on the other side; the binding strap is connected to the first connecting piece and the second connecting piece to form an annular structure; further comprising: a plurality of annular air bags; two adjacent annular air bags are connected and fixed, and the plurality of annular air bags are used for self-splicing and the shape after splicing is adjustable to match the patient's wound site; an air port is provided on the annular air bag; a Velcro surface is provided on the inner side surface of the binding strap, and a Velcro hook surface is provided on the side wall of the air bag, and the air bag can be connected to the inner side wall of the binding strap; an oxygen inlet is opened on the binding strap; the oxygen inlet is connected to the inside of the shape after the annular air bags are spliced.

[0043] like Figure 1As shown, this embodiment provides a distribution form of an annular airbag on a binding belt. Since the present application includes an annular airbag, the user can adjust the shape of the annular airbag according to actual use requirements. It can be adjusted to any regular or irregular shape to match the patient's wound site. Of course, after the annular airbag is inflated, a middle area will be formed. The shape of the middle area is more closely matched to the shape of the patient's wound site. In this way, oxygen therapy can be more targeted for the patient. The bottom side edge of the annular airbag is closely sealed to the patient's skin. In this way, it can be ensured that the oxygen in the annular airbag is not lost. Furthermore, the annular airbag can be purchased directly or customized, and it is not difficult to produce.

[0044] In this embodiment, the above-mentioned binding straps can all be made of transparent materials, which makes it easier for medical staff to observe the oxygen therapy of the patient's injured area. In order to improve the air permeability, multiple through holes can be opened on the binding straps for air permeability. Of course, the above-mentioned binding straps can be made of elastic materials.

[0045] Of course, if Figure 5 As shown: the above-mentioned binding strap can also be tied to the edge of the mask, the top of the mask is set to a transparent material, and then the annular airbag is set on the edge of the mask, so that the contact tightness between the annular airbag and the patient's skin can be further improved.

[0046] During use, the elastic binding strap can be stretched, so that when it is connected to the patient's limbs, the binding strap is stretched, and then the first connecting piece and the second connecting piece are connected to connect the above-mentioned binding strap to the patient's limbs. Of course, before the connection, the inner cavity of the annular airbag needs to be fit with the patient's trauma site.

[0047] In this embodiment, another airbag composition method is provided, see Figure 2 , Figure 3 As shown, in order to facilitate the adjustment of the combined shape of the annular airbags, the end of the annular airbag can be formed into a cone in this embodiment. In this way, an outlet is provided for the oxygen entering the annular airbag, so that an oxygen circulation can be formed. Of course, the size of the oxygen outlet depends on the degree of inflation of the annular airbag. If it is inflated more, the adjacent annular airbags will fit more closely. At this time, the oxygen outflow rate will be reduced. If it is inflated less, the gap between the adjacent annular airbags will be larger. At this time, the rate at which oxygen is discharged from the inner cavity of the annular airbag will increase. The user can set the specific setting options according to actual conditions, and this application does not limit it.

[0048] Based on the above implementation, see Figure 3 , Figure 4As shown, an annular buckle is provided at one end of the annular airbag; an annular snap ring is provided at the other end of the annular airbag; the annular buckle of one of the two adjacent annular airbags is buckled and connected with the annular snap ring of the other annular airbag; the annular airbags are connected end to end to form an annular airbag.

[0049] The annular buckle and the annular snap ring can be connected to each other, and after the connection, the two are connected, so that the two adjacent annular airbags can be connected. In this way, when the air pump inflates any one of the annular airbags, the other annular airbags can also be inflated, which is more convenient for users to operate.

[0050] In a specific embodiment, a transparent window is provided on the binding belt, and the position of the transparent window corresponds to the position of the annular airbag; the transparent window is used to observe the wound site of the patient.

[0051] In a specific embodiment, an air pump is further included, the air pump is connected to the air port on the annular airbag, and is used to inflate the annular airbag; a bottom plate is provided at the bottom of the annular airbag, and the Velcro hook surface is provided on the outer surface of the bottom plate. This makes it easier for users to connect the annular airbag to the binding belt, and it is easier for users to place the annular airbag on the binding belt into various shapes and fix them.

[0052] In a specific embodiment, it further includes: an oxygen concentrator, the oxygen supply pipe of the oxygen concentrator is connected to the oxygen inlet, and the oxygen concentrator is used to deliver oxygen to the annular airbag through the oxygen inlet to perform oxygen therapy on the patient's wound site.

[0054] On the other hand, Figure 4 As shown, a control method for a local oxygen therapy device is provided, which is used to control the above-mentioned local oxygen therapy device, including: steps S1 to S6:

[0060] Step S6. Connect the oxygen generator to the oxygen inlet through the oxygen supply tube, and supply oxygen to the annular airbag according to the supply parameters.

[0061] In a specific embodiment, the step of using the visual acquisition component to identify the patient's wound site to obtain the wound parameters of the patient's wound site includes:

[0062] The visual acquisition component acquires a picture of the patient's wound site and pre-processes the picture using a graphics pre-processing module, wherein the graphics pre-processing module includes: a denoising sub-module, a graphics enhancement sub-module, and a graphics generation sub-module;

[0063] The denoising submodule is used to smooth the wound site image using a Gaussian kernel, and perform median filtering on the smoothed wound site image, replace each pixel value with the median value of its neighboring pixel values, decompose the image by wavelet transform, perform threshold processing in the wavelet domain, and reconstruct the denoised wound site image by inverse wavelet transform;

[0064] The graphic enhancement submodule is used to adjust the contrast of the wound site image in a linear or nonlinear manner, and adjust the grayscale histogram of the wound site image, thereby enhancing the contrast of the wound site image; perform histogram equalization on the wound site image after the grayscale histogram is adjusted, and use the Laplace operator to sharpen the wound site image to enhance the edge of the target area of ​​the wound site image.

[0065] In this embodiment, the Laplace operator algorithm includes:

[0066] [\nabla^2I=\frac{\partial^2I}{\partialx^2}+\frac{\partial^2I}{\partialy^2}];

[0067] Where (I) is the grayscale value of the image, (\frac{\partial^2I}{\partialx^2}) and (\frac{\partial^2I}{\partial y^2}) are the second-order derivatives of the image in the x and y directions, respectively.

[0068] Furthermore, the image enhancement submodule is used to adjust the contrast of the wound site image in a linear or nonlinear manner, and adjust the grayscale histogram of the wound site image, which is achieved using a grayscale co-occurrence matrix; the grayscale co-occurrence matrix is:

[0069]

[0070] P,(i,j) is the value of the gray-level co-occurrence matrix P(m=1,2,x) at (i,j),

[0071]

[0072] The graphic generation submodule is used to regenerate the image processed by the graphic enhancement submodule to obtain a wound site image showing the wound contour edge.

[0073] The trained image analysis model is used to analyze the wound site image at the wound contour edge to obtain wound parameters corresponding to the wound site image at the wound contour edge.

[0078] The data sorting model is trained using multiple training sets, and the final weights are adjusted and obtained with the output data set as the result to obtain the data sorting model.

[0079] In this embodiment, an existing neural network image analysis model is used and trained using the parameters specific to this embodiment to obtain a trained image analysis model.

[0080] In a specific embodiment, formulating the nourishment parameters based on the trauma parameters includes: formulating an association relationship table between the trauma degree in the trauma parameters and the nourishment parameters; and reading and calling the corresponding nourishment parameters in the association relationship table according to the trauma parameters of the current patient.

[0081] Specifically: users can combine clinical experience to provide different oxygen supply for patients with different degrees of trauma. For example, for mild trauma, a lower supply rate and concentration can be used. If the trauma is severe, a higher supply rate and concentration can be used. This application does not limit this.

[0082] In this embodiment, the wound oxygen therapy device provides pressurized oxygen for local wound treatment, which mainly works through three mechanisms: oxygen supply, pressurization, and humidification. Supply: Oxygen, as a key factor in the wound healing process, can promote angiogenesis, collagen deposition and epithelialization, and promote wound healing by improving ischemia and hypoxia. Pressurization: Non-contact cyclic pressurization provides a pressure of 0-50mbar, which is equivalent to a level 3 conventional pressurized dressing (CCD). This helps to reduce lower limb edema and promote blood circulation. Higher positive pressure more effectively delivers oxygen deep into the wound, thereby promoting the growth of granulation tissue at the bottom. Humidification: A humid environment is conducive to the vitality of tissue cells and the migration of epithelial cells on smooth surfaces, promoting faster, more effective and lasting healing of healthy granulation tissue.

[0083] In this embodiment, a display screen can also be provided, on which a visual acquisition component, temperature, humidity, oxygen concentration detection, and device action time are provided. The visual acquisition component is used to collect and identify the size and degree of the patient's wound. The temperature, humidity, and oxygen concentration detection are used to detect the wound environment and timely adjust it to an environment suitable for the growth of the patient's wound. The oxygen generator is driven to produce 99% to 100% pure oxygen, the flow rate is controlled at 3 to 15 mL / h, the temperature is controlled at 25°C, and the humidity is controlled at 30% to 80%. A pressure detection instrument is provided on the annular airbag to prevent long-term use of the annular airbag from causing pressure damage to the skin; an absorbable exudate material is provided at the bottom of the airbag, which can be absorbed in time when the wound produces exudate and flows to the surrounding area to prevent the cleaning of the exudate from affecting the oxygen therapy, and the absorbent exudate material can be pasted and replaced.

[0084] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
