Description

Technical Field

[0001] This utility model relates to medical auxiliary devices, specifically, to a skin test observation device. Background Technology

[0002] Skin test is short for skin (or intradermal) sensitivity test. In order to prevent allergic reactions, especially severe allergic reactions, it is stipulated that some drugs that are prone to causing allergic reactions must be tested for skin sensitivity before use. Drugs with negative skin test results can be used by patients, while drugs with positive skin test results are prohibited from being used by patients.

[0003] Currently, the routine method for observing skin test results involves medical personnel injecting the skin test needle into the patient and informing them of the observation period. After the observation period, the medical personnel observe the skin in the test area. Currently, observation of the test area is generally done visually or by measuring the wheals formed on the skin with a ruler to determine the test result. Taking penicillin as an example, a positive result is characterized by a locally raised wheal with redness and hardening, a wheal diameter greater than 1 cm, or pseudopodia and itching around the redness. In severe cases, a systemic rash or anaphylactic shock reaction may occur.

[0004] Specifically, application number CN201720127634.2 discloses a skin test observation device, including a skin test observation panel. The front of the skin test observation panel has a timing area, an information recording area, and an observation area. A timer is provided on the timing area, an erasable coating plate is provided on the information recording area, and a transparent scale plate is provided on the observation area. The transparent scale plate also has a circular scale ring. The back of the skin test observation panel has a battery area and a buzzer connected to the timer. This utility model can clearly and intuitively observe and judge the size of the wheals, redness, and hard lumps on the patient's skin in the skin test area, and make an accurate judgment on the skin test results. As another example, application number CN202320934585.9 discloses a wrist-worn skin test result judgment device, including a skin test result judgment device and a wristband. The skin test result judgment device includes a first shell and a second shell, the second shell being rotatably connected to the first shell, and the wristband being connected to the skin test result judgment device. This invention uses a wristband to attach the skin test result assessment device to the patient's wrist, allowing nurses to accurately and quickly determine which patients require skin test results. The second housing is rotatable to ensure that the skin test ruler, once pulled out, rests flat against the wrist skin without folding. Furthermore, this invention can record the skin test type, determine the reminder time and result assessment based on the test type, and provide timely and rapid responses to allergic reactions. Therefore, this invention facilitates accurate skin test result assessment without the discomfort caused by the ruler pressing against the patient's skin.

[0005] In summary, medical personnel currently generally rely on visual inspection to determine test results, with some using rulers or wearing measuring tools. However, in practice, medical personnel have found that using rulers or wearing measuring tools can easily lead to contact with the skin test site, and if the measuring tools are not disinfected promptly, it can easily cause infection at the skin test site.

[0006] Therefore, it is necessary to develop or improve skin test observation devices to avoid direct contact between the skin test observation device and the skin test site. Utility Model Content

[0040] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0041] like Figures 1-5 and Figures 7-9 As shown, a skin test observation device according to one embodiment of the present invention includes a clamping seat 1, a mounting seat 2, an observer 3, and an observation frame 4. The mounting seat 2 is mounted on the clamping seat 1 and can rotate relative to the clamping seat 1. The top of the mounting seat 2 is provided with a first opening 21, and the mounting seat 2 is provided with a first through hole 22 penetrating through its two sides. The first opening 21 and the first through hole 22 communicate with each other to form a clearance. The observer 3 is used to observe the diameter of the skin induration at the skin test site. A space is reserved between the observer 3 and the bottom of the mounting seat 2 for the arm to pass through. The observation frame 4 is located in the clearance and is rotatably connected to the mounting seat 2. The observer 3 is installed in the observation frame 4.

[0042] The aforementioned skin test observation device, with its clamping base 1, allows medical staff to flexibly fix the device to target objects such as chairs and desks, expanding its application range and scenarios. The mounting base 2, which can rotate relative to the clamping base 1, and the observation frame 4, which is also rotatably connected to the mounting base 2, allows for multi-angle observation by the observer 3, matching various application scenarios and adapting to different target objects. Furthermore, it allows patients with limited arm movement to have their observation needs met by adjusting the rotation angle between the mounting base 2 and the observation frame 4. The observer 3 allows for observation of the diameter of the skin induration at the skin test site, and by comparing it with a reference table of average skin induration diameters, medical staff can clearly understand the skin test results. Moreover, a space is reserved between the observer 3 and the bottom of the mounting base 2 for the patient's arm to pass through, allowing the patient's arm to be positioned under the observer 3, improving the observation efficiency for medical staff.

[0043] This skin test observation device has a simple and reasonable structure, can be adjusted at multiple angles, and is applicable to multiple scenarios. It solves the problem of traditional measuring tools being prone to contact with the skin test site and causing infection, and also overcomes the limitation of traditional measuring tools to observe from a single angle, thus meeting the personalized needs of patients and medical staff.

[0044] Among them, such as Figure 8 As shown, the skin test observation device is clamped to the chair armrest; as Figure 9 As shown, the skin test observation device is clamped to the edge of the desk.

[0045] In one embodiment, the skin test observation device further includes a first drive device 5 for controlling the rotation of the observation frame 4 around the X-axis, the first drive device 5 being mounted on the mounting base 2. Thus, while the observation frame 4 rotates around the X-axis, the observer 3 moves synchronously with the observation frame 4, allowing the observer 3 to be aligned with the patient's arm at different clamping angles.

[0046] In one embodiment, the body of the first driving device 5 is mounted on the outer wall of the mounting base 2, and the output end of the first driving device 5 extends through the outer wall of the mounting base 2 to the clearance position and is connected to the observation frame 4.

[0047] In one embodiment, the observation frame 4 includes a frame 41 and a plurality of locking devices 42; the observer 3 is located inside the frame 41; the locking devices 42 are threadedly connected to the frame 41, and the plurality of locking devices 42 cooperate to fix the observer 3 inside the frame 41.

[0048] Preferably, there are four locking devices 42, located in pairs on both sides of the frame 41. This ensures that the observation device is securely fixed to the frame 41.

[0049] In one embodiment, the output end of the first driving device 5 is fixedly connected to the frame 41.

[0050] In one embodiment, the frame 41 includes a first mounting plate 411, a second mounting plate 412, a third mounting plate 413, and a fourth mounting plate 414. The first mounting plate 411 and the second mounting plate 412 are parallel and spaced apart, and the third mounting plate 413 and the fourth mounting plate 414 are parallel and spaced apart. Both ends of the first mounting plate 411 are detachably connected to the third mounting plate 413 and the fourth mounting plate 414, respectively. Both ends of the second mounting plate 412 are detachably connected to the third mounting plate 413 and the fourth mounting plate 414, respectively. The first mounting plate 411 is connected to the output end of the first driving device 5, and the second mounting plate 412 is rotatably connected to the mounting base 2. Thus, the detachable connection of the first mounting plate 411, the second mounting plate 412, the third mounting plate 413, and the fourth mounting plate 414 facilitates replacement and transportation.

[0051] In one embodiment, the skin test observation device further includes a second driving device 6, which is mounted on the clamping seat 1. The output end of the second driving device 6 is connected to the mounting base 2 and is used to control the rotation of the mounting base 2 around the Y-axis. Thus, when the skin test observation device is fixed to the target object by the clamping seat 1, the rotation of the mounting base 2 is controlled by the second driving device 6 to ensure that the observer 3 is aligned with the patient's arm.

[0052] In one embodiment, the clamping seat 1 includes a retainer 11, a screw 12, and an abutment block 13 that cooperates with the retainer 11 to clamp onto a target object. The retainer 11 has a second opening at its bottom and second through holes on both sides of the retainer 11, the second opening connecting to the second through holes to form a clamping position. The abutment block 13 is located within the clamping position. One end of the screw 12 extends laterally through the side wall of the retainer 11 into the clamping position and connects to the abutment block 13. The screw 12 is threadedly connected to the retainer 11. A second driving device 6 is mounted on the retainer 11. Thus, the screw 12 can be used to adjust the abutment block 13 to move away from or closer to either inner side of the retainer 11, clamping the target object by the cooperation of the abutment block 13 and the retainer 11. The target object includes, but is not limited to, tables, chairs, handles, and door frames.

[0053] In one embodiment, the second drive device 6 is located within the clamping position, and the output end of the second drive device 6 extends along the Y-axis through the card holder 11 and is connected to the mounting base 2.

[0054] In one embodiment, the top of the mounting base 2 is provided with a limiting seat 7 for defining the position of the arm, the limiting seat 7 being located within the space and below the observer 3.

[0055] Furthermore, in normal usage scenarios, the vertical projection surface of the observer 3 is located within the limiting seat 7.

[0056] The surface of the limiting seat 7 that contacts the arm is arc-shaped. This conforms to the patient's arm, making the patient more comfortable.

[0057] like Figure 6 As shown, in one embodiment, the observer 3 includes a mounting frame 31 and a measuring plate 32. The mounting frame 31 has an observation area, and the measuring plate 32 is installed within the observation area. The measuring plate 32 and the mounting frame 31 are detachably connected. One end of the locking device 42 extends through the mounting frame 31 into the observation area. The end of the locking device 42 located within the observation area has a through groove (not shown in the figure), and the edge of the measuring plate 32 is inserted into the through groove. This facilitates the disassembly and replacement of the measuring plate 32.

[0058] The measuring plate 32 is made of transparent material and is equipped with a measuring scale and a relevant information recording area. The measuring plate 32 is existing technology and will not be described in detail here.

[0059] In this way, medical staff can record patient information in the information recording area, ensuring that the measuring plate 32 corresponds to the patient and avoiding cross-infection of bacteria due to repeated use of the measuring plate 32.

[0060] In one embodiment, both the first driving device 5 and the second driving device 6 are rotary motors. Rotary motors are existing technology and will not be described in detail here.

[0061] in, Figure 1 , Figure 2 , Figure 5 and Figure 7 The diameter scale of the observer is not shown in the diagram; please refer to [link / reference needed]. Figure 4 and Figure 6 .

[0062] In one embodiment, the skin test observation device includes an image acquisition module, an image retouching module, a skin induration pattern recognition module, a skin induration size measurement module, and a wireless communication module. The image acquisition module acquires images of the skin test site and sends the acquired images to the image retouching module. The image retouching module smooths the edges of the skin induration area by traversing the entire image using structural elements and adjusts the image brightness to a preset standard value. The skin induration pattern recognition module segments and recognizes the shape of the skin induration within the obtained three-dimensional image using a preset graphic template. The skin induration size measurement module calls up a corresponding scale based on the recognition result of the skin induration pattern recognition module, measures the size of the skin induration using the called scale, and automatically outputs the measurement result. The scale can be scaled and stretched according to the size and deformation of the image. The wireless communication module sends the measurement result to a mobile terminal.

[0063] The image acquisition module is a camera, and the mobile terminal is a computer, mobile phone, or electronic watch used by medical workers.

[0064] Thus, by incorporating an image acquisition module, an image retouching module, a skin induration pattern recognition module, a skin induration size measurement module, and a wireless communication module, the system can automatically identify and measure skin indurations without the need for an observer 3 or manual observation, and finally output the measurement results.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
