Description

Technical Field

[0001] The present invention relates to the technical field of teaching aids, and in particular to a lymphedema manual lymphatic drainage teaching aid and an operation evaluation system thereof. Background Art

[0002] Lymphedema is a common complication after lymph node dissection for gynecological malignancies, breast cancer, urinary system malignancies, etc. The main causes are related to surgical methods, radiotherapy, mechanical injury, infection, effusion, obesity, and tumor recurrence.

[0003] Currently, the primary treatment for lymphedema involves comprehensive detumescence therapy, including manual lymphatic drainage, pressure therapy, skin care, and functional exercises. Manual lymphatic drainage is effective for all stages of lymphedema, including primary lymphedema of the face, limbs, and genitals; secondary lymphedema following trauma, surgery, and infection; subacute inflammation of the lymphatic vessels and surrounding tissues; and mixed venous and lymphatic limb edema. Therefore, instruction in manual lymphatic drainage is a crucial component of medical staff training, and accurate manual lymphatic drainage techniques are crucial. Furthermore, since lymphedema requires lifelong treatment, teaching patients and their families about manual lymphatic drainage is equally crucial.

[0004] After searching the existing technologies, the inventor team found in the search content that the teaching or training aids related to manual lymphatic drainage are mainly such as the technology disclosed in the Chinese patent document named "A Lymphedema Manual Lymphatic Drainage Training Teaching Aid Device", publication number CN210667430U, and publication date June 2, 2020. This type of technology relies on a human body model as a training carrier in the manual lymphatic drainage operation, and has technical problems of inconvenience in carrying and operation.

[0005] Therefore, in view of the particularity of the above-mentioned manual lymphatic drainage teaching, it is necessary to design a lymphedema manual lymphatic drainage teaching aid that can simulate lymph fluid and realize the flow of lymph fluid by pushing, and can provide real-time feedback on the strength of the trainees' pushing force. At the same time, it can be worn by trainees without taking off their outer clothes, so that medical staff, patients and their families can intuitively grasp the knowledge points of manual lymphatic drainage and improve the training effect. Summary of the Invention

[0006] The technical purpose of the present invention is to provide a lymphedema manual lymphatic drainage teaching aid and its operation evaluation system, which can simulate lymph fluid and realize the flow of lymph fluid by pushing, and can provide real-time feedback on the strength of the trainee's pushing force. At the same time, it can be worn by the trainee without taking off his outer clothes.

[0007] The technical solution 1 adopted in the present invention is as follows: A lymphedema manual lymphatic drainage teaching aid, comprising a sleeve wearable on a trainee's arm, the sleeve comprising an inner layer, a middle layer, and an outer layer arranged in sequence from inside to outside; The middle layer is provided with a plurality of independently arranged light-emitting units, which can emit light of multiple colors, and the light-emitting colors are adjustable; Each of the light-emitting units is connected to a pressure sensor, and each of the pressure sensors is used to detect the pressure exerted on the corresponding light-emitting unit; The middle layer is further provided with a controller, which is connected to the pressure sensor and the light-emitting unit respectively. The controller is used to control the light-emitting color of the corresponding light-emitting unit according to the pressure detected by the pressure sensor and the control instruction.

[0008] The above technical measures are aimed at the particularity of manual lymphatic drainage teaching. The setting of the sleeve allows students to wear it on their arms, so that students can wear the sleeve without taking off their outer clothes, which effectively improves convenience; by setting multiple independently set light-emitting units in the middle layer of the sleeve, lymph fluid simulation is achieved, and by pushing on the sleeve, the light-emitting units on the pushing path are illuminated in turn, thereby simulating the flow of lymph fluid. At the same time, each light-emitting unit is connected to a pressure sensor, which can make the light color of each light-emitting unit different according to different pushing forces, and timely feedback the student's pushing force. It helps students practice and master the correct force and method for manual lymphatic drainage operations, better master manual lymphatic drainage operation skills, and effectively improve the training effect for medical staff, patients and patients' families.

[0009] The above technical measures, by setting the sleeve to a multi-layer structure, can prevent the middle layer from directly contacting the trainee's skin, which is conducive to improving comfort. At the same time, it is conducive to protecting electronic components from external interference and extending service life.

[0010] Furthermore, the control instruction includes: setting a normal pressure interval, a low pressure interval and a high pressure interval, setting color one for the normal pressure interval, setting color two for the low pressure interval, and setting color three for the high pressure interval.

[0011] The above technical measures set normal pressure intervals, low pressure intervals and high pressure intervals, and set a color label for each pressure interval. The controller matches according to the pressure, obtains the color label of the matching pressure interval, and controls the luminous color of the corresponding light-emitting unit according to the color label. This helps trainees to directly understand whether the force is standard, so as to better master the correct force and method of manual lymphatic drainage operations.

[0012] Furthermore, a direction indicator mark is provided on the outer layer of the sleeve.

[0013] The above technical measures help trainees to correctly identify the pushing direction and improve the training effect by providing direction indication marks on the outer layer of the sleeve.

[0014] Furthermore, the outer layer of the sleeve is a transparent structure.

[0015] The above technical measures, by setting the outer layer of the sleeve as a transparent structure, are conducive to enhancing the visual effect of the light-emitting unit, and are conducive to trainees to more intuitively observe the light-emitting color of the light-emitting unit, so as to better master the correct strength and method of manual lymphatic drainage operations.

[0016] Furthermore, the teaching aid has two sleeves, corresponding to the two arms of the trainee respectively.

[0017] In the above technical measures, the teaching aid has two sleeves, which correspond to the two arms of the trainee respectively, support the training of two arms, increase the training scenarios, and are conducive to improving training efficiency.

[0018] Furthermore, the teaching aid further comprises a body that cooperates with the two sleeves and can be worn by the trainee; The body of the garment is matched with the two sleeves to form a garment structure that can be worn and fixed on a student.

[0019] The above technical measures provide a body, which cooperates with the sleeves to form a top structure, making it easier for students to wear and fix the garment, thereby improving convenience, ensuring that the teaching aids will not shift during use, and enhancing wearing stability.

[0020] Furthermore, the body of the garment is in an inwardly concave arc shape on both sides corresponding to the trainee's waist.

[0021] The above technical measures are beneficial to improving wearing comfort and fit by setting the two sides of the body corresponding to the trainee's waist to an inward concave arc shape, which fits the waist curve of the human body, and is also beneficial to improving the stability of the trainee during operation.

[0022] Furthermore, an adjustment mechanism is provided at a position of the garment body corresponding to the trainee's waist, and the adjustment mechanism is used to adjust the waist size of the garment body.

[0023] The above technical measures provide an adjustment mechanism at the position of the garment body corresponding to the trainee's waist, so that the trainee can flexibly adjust the waist size of the garment body according to his or her body shape, which is conducive to improving versatility.

[0024] The second technical solution adopted by the present invention is as follows: An operation evaluation system for the lymphedema manual lymphatic drainage teaching aid according to the above technical solution 1, The operation evaluation system includes a processor and a display screen, wherein the processor is connected to the controller and the display screen respectively, and is used to obtain the number of light-emitting units that emit light and the number of light-emitting units that emit light in color 1 during the trainee's operation, and obtain the operation standard rate according to the evaluation procedure; The display screen is used to display the operating standard rate.

[0025] In the above technical measures, the processor obtains the number of light-emitting units that emit light and the number of light-emitting units that emit light in color one during the trainee's operation, obtains the operation standard rate according to the evaluation procedure, and displays the operation standard rate on the display screen, quantitatively evaluates the trainee's operation, provides objective feedback, and helps the trainee to intuitively understand his or her own operation level.

[0026] Furthermore, the evaluation procedure includes: S1, calculating the proportion of the number of luminous light-emitting units in the number of light-emitting units to obtain a first proportion result; S2, calculating the proportion of the number of light-emitting units emitting color one in the total number of light-emitting units to obtain a second proportion result; S3: Perform weighted calculation on the first proportion result and the second proportion result to obtain an operation standard rate.

[0027] The above technical measures evaluate the students' operations through quantitative methods, which is conducive to avoiding errors in subjective judgment, improving the scientific nature and objectivity of the evaluation, and allowing students to intuitively see their own operation level through the operation standard rate, which is conducive to enhancing the motivation and enthusiasm for learning.

[0028] One or more technical solutions provided by the present invention have at least the following technical effects or advantages: The present invention aims at the particularity of manual lymphatic drainage teaching. Through the setting of the sleeve, the trainees can wear the sleeve on their arms, so that the trainees can wear the sleeve without taking off their outer clothes, which effectively improves convenience; by arranging a plurality of independently set light-emitting units in the middle layer of the sleeve, the simulation of lymph fluid is achieved, and by pushing on the sleeve, the light-emitting units on the pushing path are illuminated in turn, thereby realizing the simulation of lymph fluid flow; at the same time, each light-emitting unit is connected to a pressure sensor, which can make the light-emitting color of each light-emitting unit different according to different pushing forces, and timely feedback the trainees on the degree of pushing force, thereby helping trainees to practice and master the correct force and method for manual lymphatic drainage operations, better master the manual lymphatic drainage operation skills, and effectively improve the training effect for medical staff, patients and patients' families.

[0039] Specifically, the middle layer 12 has a carrier, and multiple independently arranged light-emitting units 2, controllers 4 and pressure sensors 3 are all fixed on the carrier. The specific fixing method can be determined according to actual conditions and is not specifically limited in this embodiment; the carrier is detachably connected to the inner layer 11 and the outer layer 13 by Velcro.

[0040] The control instructions include: setting a normal pressure interval, a low pressure interval and a high pressure interval, setting color one for the normal pressure interval, setting color two for the low pressure interval, and setting color three for the high pressure interval.

[0041] Among them, the normal pressure range can be 30-40 mmHg, the low pressure range is less than 30 mmHg, and the high pressure range is higher than 40 mmHg; color one can be green, color two can be yellow, and color three can be red; specific parameters can be adjusted according to actual conditions.

[0042] The outer layer 13 of the sleeve 1 is provided with a direction indicator 5. It can be an arrow mark or other marks.

[0043] The outer layer 13 of the sleeve 1 is a transparent structure, and may also be other structures capable of displaying the luminous color of the luminous unit 2 .

[0044] The teaching aid has two sleeves 1, corresponding to the two arms of the trainee respectively.

[0045] The teaching aid further comprises a body 6 which is wearable on the trainee and matches the two sleeves 1; The body 6 cooperates with the two sleeves 1 to form a top structure that can be worn and fixed on the trainee.

[0046] The body 6 is in an inwardly concave arc shape at two sides corresponding to the waist of the trainee.

[0047] An adjusting mechanism 7 is provided at a position of the garment body 6 corresponding to the waist of the trainee, and the adjusting mechanism 7 is used to adjust the waist size of the garment body 6 .

[0048] The adjustment mechanism 7 may be a waist belt structure or a Velcro structure.

[0049] Based on the above-mentioned lymphedema manual lymphatic drainage teaching aid, this embodiment further proposes an operation evaluation system, which includes a processor and a display screen. The processor is connected to the controller 4 and the display screen respectively. The processor is used to obtain the number of light-emitting units 2 that emit light and the number of light-emitting units 2 that emit light in color 1 during the trainee's operation, and obtain the operation standard rate according to the evaluation procedure; The processor is respectively connected to the controller 4 and the display screen by signals, and other connection modes are also possible.

[0050] The display is used to display the operating standard rate. The operating standard rate can also be displayed in other ways according to actual conditions.

[0051] The evaluation procedure includes: S1, calculating the proportion of the number of luminous light-emitting units 2 in the number of light-emitting units 2 to obtain a first proportion result; S2, calculating the proportion of the number of light-emitting units 2 emitting color 1 in the total number of light-emitting units 2 to obtain a second proportion result; S3, performing weighted calculation on the first proportion result and the second proportion result to obtain the operation standard rate.

[0052] The weight of the first proportion result may be 0.4, and the weight of the second proportion result may be 0.6. The specific weight distribution depends on the actual situation and is not specifically limited in this embodiment.

[0053] The middle layer 12 is also provided with a power supply, which supplies power to the light emitting unit 2, the controller 4 and the pressure sensor 3 respectively. Correspondingly, the outer layer 13 is provided with a power switch (not shown in the drawings) connected to the power supply.

[0054] The middle layer 12 is also provided with a temperature sensor, which is connected to the controller 4 by signal. The temperature sensor is used to detect the temperature of the trainee in real time. If the temperature exceeds a preset maximum temperature (for example, 39°C), the controller 4 controls the light-emitting unit 2 to not emit light.

[0055] When in use, the student wears the teaching aid with the upper structure, adjusts the waistline through the adjustment mechanism 7 to make the teaching aid fit the body, turns on the power switch, and pushes in the direction of the direction indicator 5. The pressure sensors 3 connected to each light-emitting unit 2 under the pushing path detect the pressure exerted on the corresponding light-emitting unit 2 in real time and send it to the controller 4. The controller 4 adjusts the light color of each light-emitting unit 2 according to the pushing force. For example, when the pressure detected by the pressure sensor 3 corresponding to one of the light-emitting units 2 is 35 mmHg, the controller 4 controls the light-emitting unit 2 to emit green light. If the detected pressure is 20 mmHg, the controller 4 controls the light-emitting unit 2 to emit yellow light. If the detected pressure is 5 0mmHg, the controller 4 controls the light-emitting unit 2 to emit red light; after the operation is completed, the processor obtains the number of light-emitting units 2 that emit light and the number of light-emitting units 2 that emit green light during the operation of the trainee, and obtains the operation standard rate according to the evaluation procedure. In this embodiment, the number of light-emitting units 2 that emit light is 60, the number of light-emitting units 2 that emit green light is 40, and the number of light-emitting units 2 is 80 as an example. The first proportion result is 60 / 80, that is, 0.75, and the second proportion result is 40 / 80, that is, 0.5. Through weighted calculation, 0.75*0.4+0.5*0.6=0.6, and the operation standard rate is 0.6 (that is, 60%). After the operation is completed, the trainee can see his or her own operation standard rate on the display screen.

[0056] When the trainee does not perform a pushing operation, the controller 4 controls the light emitting unit 2 not to emit light.

[0057] The simulation in this embodiment is only for understanding the pictographic requirements of training and teaching, and the simulation requirements for lymph fluid are not high.
