Detailed Description

Referring to fig. 1-6, the sampling device for dermatological department of the present invention comprises two expansion legs 4, wherein the rear ends of the two expansion legs 4 are integrally connected and distributed in a V-shape, the two expansion legs 4 have elasticity, the two expansion legs 4 can be elastically deformed under the driving of external force to enable the front ends of the two expansion legs to approach each other, and the two expansion legs 4 can automatically reset to an open state after the external force is removed; the front ends of the two expansion legs 4 are respectively fixed with a sampling pin 1, the opposite surfaces of the two sampling pins 1 are called matching surfaces 2, a collecting groove 3 is arranged on the matching surface 2 of one sampling pin 1, the collecting groove 3 is used for containing a skin sample, and a cutter 6 is arranged on the matching surface 2 of the other sampling pin 1; the two expansion legs 4 are extruded by external force, and the two sampling feet 1 can be driven to approach until the two sampling feet are closed; in the process that the two sampling feet 1 approach, the cutting knife 6 is matched with one side of the collecting tank 3 so as to cut an article (pathological skin) positioned between the two sampling feet; when the two sampling pins 1 are closed, the two matching surfaces 2 are tightly attached together, so that the collecting tank 3 is in a closed state; in the two sampling legs 1, one sampling leg 1 is provided with a locking buckle 5 capable of being rotatably adjusted, the other sampling leg 1 is provided with a buckle groove 8, and the locking buckle 5 is provided with a clasp 7 matched with the buckle groove 8; when the two sampling pins 1 are in a closed state, the locking buckle 5 is rotated to enable the hook 7 to be buckled and hung in the buckle groove 8, so that the two sampling pins 1 are locked in the closed state; when the locking buckle 5 is located at the initial position, the clasp 7 is not matched with the buckle groove 8, and the locking buckle 5 does not limit the relative movement of the two sampling pins 1.

referring to fig. 3-6, when a lesion skin is clinically sampled, a lesion skin which is about to fall off but not fall off is selected, two sampling pins 1 are used to clamp one end of the lesion skin which is tilted, a collecting tank 3 is positioned at the lower side of a cutter 6, two expansion legs 4 are squeezed to drive the two sampling pins 1 to approach, the cutter 6 is matched with one side of the collecting tank 3 to shear the lesion skin between the two sampling pins, the sheared lesion skin falls into the collecting tank 3 in a proper manner, if one-time sampling is not ideal, sampling can be carried out for multiple times by opening and closing the two sampling pins 1, after sampling is ideal, the two expansion legs 4 are squeezed to drive the two sampling pins 1 to be closed, then a locking buckle 5 is rotated to enable a hook 7 to be buckled in a buckling groove 8, the two sampling pins 1 are locked and maintained in a closed state, and the skin sample to be taken is sealed in the collecting tank 3 for being sent for inspection.

Clinically, when utilizing this sampling device for dermatology to take a sample to pathological change skin, convenient operation, labour saving and time saving, it is swift high-efficient.

The sampling device for the dermatology department has multiple functions of shearing, containing, sealing and the like, does not need to be assisted by tools such as tweezers and scissors, and reduces the clinical implementation cost of skin sampling to a certain extent.

Referring to fig. 5, because the structure design of the sampling device for dermatology is ingenious, the skin sample taken out in the sampling process does not need to be contacted with other devices, and is not easy to fall off, the use is safer, and the detection result is more accurate; meanwhile, the cutter 6 is arranged at a more reasonable position, so that the intact skin can not be cut in the sampling process, and the injury to a patient can be avoided.

In addition, this sampling device for dermatology department can regard as pathological change skin clipper in clinical use, for example can cut the ecdysis that diseases such as tinea pedis, eczema caused, and collecting vat 3 can collect the pathological change skin under the shearing along with shearing in the use, can avoid causing pollution and convenient and fast.

Further, referring to fig. 1 and 3, the dilating legs 4 and the corresponding sampling foot 1 are integrated and distributed in a shape of a pair, so that the sampling device for dermatology is more convenient to hold and more convenient and smooth for clinical use.

Further, in the case of the dermatological sampling device, the materials for the expansion leg 4 and the sampling foot 1 are variously selected, and two preferable modes are:

firstly, the expansion leg 4 and the sampling foot 1 are both made of disposable plastic materials, and the sampling device for dermatology is disposable.

Secondly, the expansion leg 4 and the sampling foot 1 are both made of metal materials, and the sampling device for dermatology can be recycled.

Further, referring to fig. 4, 5 and 6, grooves 9 for accommodating the locking buckles 5 are formed on the outer walls of the two sampling pins 1; the locking buckles 5 and the buckling grooves 8 are arranged in the corresponding grooves 9; therefore, the sampling device for the dermatology department can be ensured to have simpler appearance and more compact structure.
