Caliper-type grabbing device for collecting skin tissue fluid

Abstract

The invention provides a caliper-type grabbing device for collecting a skin tissue fluid. The device consists of a slave roller, a disposable silicone sleeve, a return steel, an adjusting handle, fixed threads, a rail window, a cavity rail, a bullet hole, an elastic wire, a spring, an elastic seat, a fixing hole, a rotating sleeve, a main roller and a skin rolling handle. The device is designed byusing the caliper projectile principle and the rolling principle of a twisting roller, so that the operation force is controllable and adjustable. The friction force between the skin and the roller is utilized to make the grabbing effect obvious. Especially for patients with infectious diseases, the operator does not directly contact with the skin of the patient during operation and executes theoperation by different hands during tissue scraping, thus being safe and reliable. By the device of the invention, the disadvantages and deficiencies existing in the bare-hand collection of tissue fluids in the prior art are solved; the grabbing, pressing and fixing of corresponding movable skins can be completely realized; the gap of lack of relevant medical devices in related fields is also filled; and auxiliary devices are provided for the collection and extraction of skin tissue fluids of patients.

Description

technical field [0001] The invention belongs to experimental devices, and relates to an auxiliary device for physical examination of leprosy patients, in particular to a caliper-type grabbing device for collecting tissue fluid from the skin, which is suitable for the preliminary preparation of tissue fluid collection from human skin and other tissues, avoiding invasive operations and infection etc. Background technique [0002] Leprosy patients are natural hosts of M. leprae. Bacillus leprae is widely distributed in patients, mainly found in certain cells of the reticuloendothelial system such as skin, mucous membranes, peripheral nerves, lymph nodes, liver and spleen. Bacillus leprae is mainly excreted from the body through ulcerated skin and mucous membranes. Other bacillus leprae can also be found in breast milk, tears, semen and vaginal secretions, but the amount of bacteria is very small. The routine inspection methods for leprosy patients mainly include regular detec...

AI Technical Summary

Problems solved by technology

Because leprosy patients need to collect specimens regularly, the age is long, and the leprosy pathology damages the skin and nerves of the extremities, the skin tissue on the body surface is severely hyperplastic, the activity is poor, and the body fluid circulation is not good, which adds a lot to the clinical work of medical workers. difficulty

[0004] The shortcomings of the current method of collecting tissue fluid from leprosy patients: (1) severe hyperplasia of skin tissue, laborious manual pressure; (2) poor skin mobility, difficulty in manual picking; (3) uneven manual pressure, easy to bleed; (4) All manual operation, low work efficiency; (5) Grabbing, scraping, collection, etc. require close cooperation of both hands, and the success rate of collection is low; (6) All manual operation, lack of research and development of related medical equipment; (7) Operators Direct contact with the patient's skin during operation increases the risk of infection; (8) The safety is not good, and the scraper is easy to accidentally injure the operator himself
