[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0031] Example 1
[0032] A skin sample collection device for dermatology, such as Figure 1-8 As shown, the device includes a protective shell 1, a placement hole 2, a first clamping plate 3, a first limiting block 4, a first return spring 5, a screw 6, a pressing mechanism 7, a replacement mechanism 8, and a scraping mechanism 9. The protective shell 1 has a placement hole 2 in the middle of its front side, a sliding groove in the right side, and a through opening at the bottom. The protective shell 1 has a first clamping plate 3 in the middle of its interior, a sliding groove in the bottom rear side of the first clamping plate 3, a first limiting block 4 slidingly mounted on the top of the first clamping plate 3, and the first limiting block 4 slidingly engaging with the protective shell 1. Two first return springs 5 are connected between the first limiting block 4 and the protective shell 1. The protective shell 1 has a screw 6 internally threadedly connected in the middle, and the lower end of the screw 6 is connected to the first limiting block 4. Both the first limiting block 4 and the first clamping plate 3 are fitted with sponge pads. The protective shell 1 has a pressing mechanism 7 in the front of its interior, which slides with the first clamping plate 3. The protective shell 1 has a replacement mechanism 8 inside, and the protective shell 1 has a scraping mechanism 9 in the rear of its interior.
[0033] When hand restraint is required, first, the spray can is placed on the replacement mechanism 8. Then, the screw 6 is rotated, causing the first limiting block 4 to move upward. The first return spring 5 is compressed, and the first limiting block 4 moves upward until it no longer contacts the first clamping plate 3. The hand is then placed along the placement hole 2 onto the first clamping plate 3. The sponge pad on the first clamping plate 3 relaxes the hand. At this time, the screw 6 is rotated in the opposite direction, causing the first limiting block 4 to move downward. The first return spring 5 acts as a buffer, and the first limiting block 4 moves downward to restrain the hand. Simultaneously, the hand squeezes the pressing mechanism 7, causing it to move downward, thereby squeezing the spray can on the replacement mechanism 8. The spray can on the replacement mechanism 8 sprays disinfectant onto the hand, disinfecting it. Then, the skin scraping mechanism 9 is activated, moving forward to scrape off the skin from the hand. The scraped skin is collected, ultimately achieving the purpose of restraining the hand. After the operation is completed, the skin scraping mechanism 9 is turned off.
[0034] The pressing mechanism 7 includes a support rod 70, a first pressing block 71, a first inclined block 72, a second return spring 73, a second inclined block 74, a second pressing block 75, and a third return spring 76. The support rod 70 is connected between the left and right sides of the lower end inside the protective shell 1. The first pressing block 71 is slidably provided inside the support rod 70. The first pressing block 71 passes through the first clamping plate 3. Two second return springs 73 are connected between the first pressing block 71 and the support rod 70. The first inclined block 72 is connected to the rear side of the first pressing block 71. The second pressing block 75 is slidably provided on the front side of the bottom of the first clamping plate 3. The second inclined block 74 is connected to the front side of the second pressing block 75. The second inclined block 74 is located behind the first inclined block 72. The first inclined block 72 and the second inclined block 74 are slidably engaged. The third return spring 76 is connected between the second inclined block 74 and the first clamping plate 3.
[0035] When hand disinfection is needed, the person places their hands on the first clamp 3, pressing the first pressing block 71. The first pressing block 71 moves downward, compressing the second return spring 73. Simultaneously, the first pressing block 71 moves the first inclined block 72 downward, pressing the second inclined block 74. The second inclined block 74 then moves backward, compressing the third return spring 76. The second inclined block 74 moves the second pressing block 75 backward, pressing the spray can and spraying disinfectant onto the person's hands. The disinfectant effectively disinfects the hands. To disinfect people's hands and improve the quality of subsequent skin sample collection, when people's hands are not in contact with the first pressing block 71, the first pressing block 71 moves upward and resets under the reset action of the second reset spring 73. The first pressing block 71 drives the first inclined block 72 to move upward, and the first inclined block 72 will not squeeze the second inclined block 74. Under the reset action of the third reset spring 76, the second inclined block 74 moves forward and resets, and then the second pressing block 75 will no longer squeeze the spray can, so the spray can will no longer spray disinfectant, ultimately achieving the purpose of disinfecting hands.
[0036] The replacement mechanism 8 includes a protective plate 80, a first support block 81, a second clamping plate 82, a fourth return spring 83, and a pressing rod 84. The protective plate 80 is hinged to both the left and right sides of the lower part of the protective shell 1. The first support block 81 is provided on the front side inside the protective shell 1. The first support block 81 is located behind the support rod 70. The second clamping plate 82 is slidably provided inside the first support block 81. Two fourth return springs 83 are connected between the second clamping plate 82 and the first support block 81. The pressing rods 84 are connected to both the left and right sides of the second clamping plate 82.
[0037] When the disinfectant solution is used up and needs to be replaced, people pull the protective plates 80 on both sides to rotate and open it. Then, they pull the pressing rod 84 to move the second clamping plate 82 downward. The fourth return spring 83 is compressed, and the second clamping plate 82 moves the spray can downward. The spray can is no longer in contact with the first clamping plate 3, and people can take out the spray can for replacement. After replacement, people stop applying force to the pressing rod 84. Under the reset action of the fourth return spring 83, the second clamping plate 82 moves upward, moving the spray can upward. Then, people push the protective plate 80 to rotate in the opposite direction to close it, thus achieving the purpose of replacing the spray can.
[0038] The peeling mechanism 9 includes a first support base 90, an electric slide rail 91, a start button 92, a second support block 93, a scraper 94, a third inclined block 95, and a fifth return spring 96. The first support base 90 is connected to the rear side inside the protective shell 1. The electric slide rail 91 is installed on the top of the first support base 90. The start button 92 is slidably provided in the middle of the rear side of the electric slide rail 91. The start button 92 and the electric slide rail 91 are electrically connected. The second support block 93 is slidably provided inside the electric slide rail 91. The scraper 94 is slidably provided in the top of the second support block 93. Two fifth return springs 96 are connected between the scraper 94 and the second support block 93. The third inclined block 95 is connected to both the front and rear sides of the upper part of the scraper 94.
[0039] When it is necessary to collect skin samples, press the start button 92 to activate the electric slide rail 91. This causes the second support block 93 to move forward along the electric slide rail 91. The second support block 93 then drives the scraper 94 to move forward along the first clamping plate 3. When the scraper 94 moves forward and aligns with the sliding groove on the first clamping plate 3, the fifth return spring 96 is initially compressed. Under the reset action of the fifth return spring 96, the scraper 94 slowly moves upward to contact the skin, reducing harm. The scraper 94 continues to move forward, scraping off the skin surface. When the electric slide rail 91 drives the second support block 93 to move backward, the second support block 93 drives the scraper 94 to move backward. When the scraper 94 moves backward and no longer aligns with the sliding groove on the first clamping plate 3, the first clamping plate 3 will press the scraper 94, causing it to move downward. This ultimately achieves the purpose of collecting skin samples. After the operation is completed, press the start button 92 to close the electric slide rail 91.
[0040] Example 2
[0041] Based on Example 1, such as Figures 9-12 As shown, it also includes an activation mechanism 10, which includes a third support block 100, a third pressing block 101, a second limiting block 102, a third limiting block 103, a sixth return spring 104, a second support base 105, a fourth inclined block 106, and a seventh return spring 107. The second support base 105 is connected to the rear side of the inside of the protective shell 1 and is connected to the electric slide rail 91. The third support block 100 is connected to the rear side of the inside of the protective shell 1, and the third support block 100 has a sliding arrangement inside it. The third pressing block 101 is connected to the second limiting block 102 on both the left and right sides. The third support block 100 is connected to the third limiting block 103 on both the left and right sides at the bottom. The second limiting block 102 and the third limiting block 103 are connected to the sixth return spring 104. The rear side of the first support base 90 is provided with a fourth inclined block 106, which is slidably engaged with the second support base 105. The fourth inclined block 106 and the first support base 90 are connected to two seventh return springs 107.
[0042] When the electric slide rail 91 needs to be automatically started, when a person places their hand on the first clamping plate 3, they simultaneously press the third pressing block 101. The third pressing block 101 drives the second limiting block 102 to move downward, compressing the sixth return spring 104. The third pressing block 101 moves downward and presses the fourth inclined block 106, causing the fourth inclined block 106 to move forward. The seventh return spring 107 is compressed, and the fourth inclined block 106 moves forward and presses the start button 92, thus starting the electric slide rail 91. When the person's hand is no longer in contact with the third pressing block 101, under the reset action of the sixth return spring 104, the third pressing block 101 drives the second limiting block 102 to move upward and reset. The third pressing block 101 no longer presses the fourth inclined block 106. Under the reset action of the seventh return spring 107, the fourth inclined block 106 moves backward and reset, no longer pressing the start button 92. Ultimately, the purpose of automatically starting the electric slide rail 91 can be achieved.
[0043] It also includes a collection mechanism 11, which includes a limiting rail 110, a collection frame 111 and a first filter screen 112. The limiting rail 110 is connected to the upper left side of the first support base 90. The collection frame 111 is slidably provided inside the first support base 90. The collection frame 111 has multiple openings. The collection frame 111 is slidably engaged with the limiting rail 110. The first filter screen 112 is installed inside the collection frame 111.
[0044] When the scraped skin sample falls onto the first filter 112, people pull the collection frame 111 forward along the limiting rail 110. The collection frame 111 moves the first filter 112 forward, and at the same time moves the skin sample forward. The protective shell 1 has a sliding groove on the right side, and the collection frame 111 moves out along the sliding groove of the protective shell 1. People take out the collection frame 111, thereby collecting the skin sample. Finally, the purpose of collecting the scraped skin sample can be achieved.
[0045] It also includes an adsorption mechanism 12, which includes a motor 120, a fan blade 121, a second filter 122, and a suction plate 123. The suction plate 123 is connected to the bottom of the first support base 90 and corresponds to the opening of the protective shell 1. The motor 120 is installed on the top of the suction plate 123 and is located inside the first support base 90. The fan blade 121 is connected to the output shaft of the motor 120, and the second filter 122 is installed inside the first support base 90.
[0046] When it is necessary to prevent the scraped skin sample from being blown away, the motor 120 is started to reverse. The motor 120 drives the fan blade 121 to rotate in the opposite direction. Through the multiple openings on the collection frame 111, the fan blade 121 rotates in the opposite direction to pick up the scraped skin sample and pick it up above the first filter 112. People can then collect the skin sample. This can ultimately achieve the purpose of preventing the scraped skin sample from being blown away. After the operation is completed, the motor 120 can be turned off.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
