Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an evaluation ruler for oral mucosal pressure injury. Background Art

[0002] Oral mucosal pressure injury refers to local mucosal injury caused by the use of medical devices. This kind of injury is common in patients wearing dentures, dental braces, using endotracheal intubation and other medical devices. If not detected and treated in time, it may cause more serious oral health problems, such as pain, bleeding, ulcers, infections, tissue adhesions, and functional disorders, which not only greatly increase the pain of patients and affect the prognosis of diseases, but also increase the workload of medical staff. Therefore, early and accurate evaluation and diagnosis of oral mucosal pressure injury are particularly important.

[0003] Existing pressure injury evaluation tools are mainly for skin pressure injury and are not applicable to oral mucosal pressure injury. Oral mucosa consists of the epithelial layer, lamina propria, submucosa and basal layer, while the skin is composed of the epidermis, dermis and subcutaneous tissue. Therefore, there are differences in evaluating oral mucosal pressure injury and skin pressure injury. Moreover, the internal environment of the oral cavity is complex and dim, and there are great challenges in directly observing and evaluating the condition of oral mucosa. The traditional pressure injury evaluation ruler cannot directly examine the inside of the oral cavity and relies on the cooperation of a light source and a mirror. However, due to problems such as insufficient light, limited field of vision and limited internal space of the oral cavity, it is often difficult to comprehensively and accurately detect early subtle injuries. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an evaluation ruler for oral mucosal pressure injury. The evaluation ruler is provided with a light strip, which can provide sufficient and uniform illumination inside the oral cavity while directly measuring the pressure injury site inside the oral cavity; the evaluation ruler is also provided with a scroll device, and the affected area can be more conveniently compared and staged through the graphic curtain in the scroll device.

[0024] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and cannot be construed as a limitation to the present utility model.

[0025] As Figure 1As shown in the figure, the utility model provides an oral mucosa pressure injury assessment ruler, which comprises a ruler body 1. The ruler body 1 has two opposite ruler surfaces, and one of the ruler surfaces is a measuring surface 2 for measurement. A measuring scale 4 is arranged along the top edge of the measuring surface 2, and the measuring scale 4 extends to the first end 21 of the ruler body 1. The top of the ruler body 1 has a ruler ridge 3, and the ruler ridge 3 is connected to the top edges of both ruler surfaces at the same time. A card slot 10 is formed inside the ruler ridge 3, and a light strip 5 is arranged in the card slot 10. The ruler-shaped structure of the tool of the utility model takes into account the characteristics of the narrow space inside the oral cavity and has high flexibility and convenience; the light strip 5 can provide sufficient light, and the measuring scale 4 is arranged at the connection between the ruler ridge 3 and the measuring surface 2, which makes it more convenient to measure and read the scale in cooperation with the light strip 5.

[0026] Among them, the light strip 5 is of the same length as the measuring scale 4 and is arranged parallel to the measuring scale 4 to ensure that sufficient lighting is provided for each part used for measurement and the overall lighting brightness is uniform.

[0027] Specifically, a part of the measuring surface 2 without the measuring scale 4 is for medical staff to hold, and a light strip switch 6 is arranged at the second end 22 of the ruler body 1 to improve the convenience of use. The light strip switch 6 is electrically connected to the light strip 5, and a battery 9 is also installed inside the ruler body 1 to provide power for the light strip 5.

[0028] Combined with Figure 1-2 As shown in the figure, specifically, a light condensing part 7 is arranged on the top of the ruler ridge 3. The light condensing part 7 is made of a transparent and focusable material, so that after being irradiated by the light strip 5 below, the light can be transmitted and focused. Preferably, the light condensing part is a regular triangular prism. The side length of the triangular bottom surface of the regular triangular prism is equal to the width of the ruler ridge 3, the side edge is equal to the length of the ruler ridge 3, and the two side edges of the regular triangular prism are respectively connected to the two ruler surfaces, so as to realize a smooth transition at the connection between the regular triangular prism and the two ruler surfaces and a suitable fit with the ruler ridge 3.

[0029] On the other hand, the structure of the regular triangular prism can prevent the light from being blocked when approaching the measurement, and plays a role in separating between the light strip 5 and the measurement part; in addition, due to the inevitable certain thickness of the ruler body 1, by setting the regular triangular prism, the edge of the triangle can be used to provide a clearer and more intuitive boundary, improving the alignment and measurement accuracy. In addition, the structure of the regular triangular prism can also focus the light on the third side edge for alignment and measurement to a certain extent, making the measurement process clearly visible.

[0030] Such as Figure 3As shown, specifically, a reel device 8 is further provided on the ruler body 1. The reel device 8 includes a main shaft 81 installed in the accommodation cavity inside the ruler body 1, and a graphic curtain 82 wound around the main shaft 81. The main shaft 81 is rotatably connected to the ruler body. One end of the graphic curtain 82 is connected to the main shaft 81, and a torsion spring 83 is also connected between the main shaft 81 and the graphic curtain 82. The design of the reel can save the occupied space of the graphic curtain 82 and directly hide the graphic curtain 82 inside the ruler body 1. By setting the torsion spring 83, when the graphic curtain 82 is pulled out and unfolded outward, the torsion spring 83 will also be stretched and store elastic potential energy. After releasing the graphic curtain 82, the torsion spring 83 releases the energy it stores and automatically winds the graphic curtain 82 back onto the main shaft 81, thus realizing the automatic rewinding function of the graphic curtain 82. This function makes it more convenient and fast for the user to unfold and retract the graphic curtain 82.

[0031] For the convenience of operation, a through hole 88 communicating with the accommodation cavity 87 is provided on the measuring surface 2, so that the other end of the graphic curtain 82 passes through the through hole 88 and out of the ruler body 1 after winding around the outer periphery of the main shaft 81. A limiting block 84 is provided at the end of the graphic curtain 82 that passes out of the ruler body. By setting the limiting block 84, the end of the graphic curtain 82 that passes out of the ruler body 1 can be stuck at the through hole 88, which is convenient for pulling out the graphic curtain 82 and preventing the graphic curtain 82 from completely retracting when retracting.

[0032] Among them, the graphic curtain 82 includes a text description area 85 and a graded picture area 86. The graded picture area 86 can display legends of oral mucosal pressure injuries at different grades for medical staff to quickly compare and evaluate; the text description area 85 provides detailed descriptions, evaluation criteria, and usage instructions for oral mucosal pressure injuries. Through the combination of fonts and pictures, medical staff can more quickly identify and evaluate the degree of pressure injury during the evaluation process.

[0033] The present utility model is specifically implemented in the following manner: The medical staff holds the holding part of the ruler body 1, turns on the light strip switch 6, inserts the ruler body 1 into the patient's oral cavity, and irradiates the pressure injury site and the surrounding oral mucosa through the light strip 5 for evaluation. The evaluation information includes: wound site, tissue type, color, signs of infection, etc. At this time, the medical staff can also use the other hand to pull the limiting block 84 to pull out and unfold the graphic curtain 82 outside the patient's oral cavity, compare the text description area 85 and the graded picture area 86 on the graphic curtain 82, so as to identify and judge the stage of the pressure injury degree. After the comparison is completed, releasing the limiting block 84 allows the graphic curtain 82 to be retracted into the ruler body 1. On the other hand, the medical staff can also rely on the illumination of the light strip 5 to gently stick the ruler ridge 3 with the light strip 5 to the edge of the pressure injury site, mark the length and width dimensions of the affected area according to the measurement scale 4, and calculate the area of the pressure injury site, so as to facilitate judging the patient's recovery situation and preventing the occurrence of complications.

[0034] The above are only some embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
