Problems solved by technology

[0003] However, because the existing body fluid collection device guides the collected body fluid through the slideway during use, the body fluid enters the interior of the storage tube, and the surface of the storage tube has no blocking cover, which causes the backflow of the body fluid, which affects the normal preservation of the body fluid, resulting in unnecessary Trouble

Embodiment 1

[0031] Such as Figure 1-2 As shown, a contact-free body fluid collection device includes a storage device 4, the front end of the storage device 4 is fixed with a chute 3, the upper end of the storage device 4 is connected with a fixed tube 2 through screw rotation, and the upper end of the fixed tube 2 is fixed with a package Device 1, the storage device 4 comprises a shell 43, the inner surface of the shell 43 is slidingly connected with a storage tube 44, the top of the storage tube 44 is fixed with a guide tube 45 at the inner position of the shell 43, and the inside of the storage tube 44 is connected by a threaded rotation. The fixed cover 42 is fixed with a connecting rod 41 on the upper end of the fixed cover 42 , and a sealing cover 46 is fixed on the upper end of the connecting rod 41 .

[0032] Place the wrapping device 1 on the surface of the lips, and let the head hang down, so that the saliva in the oral cavity enters the wrapping device 1. The saliva moves down...

Embodiment 2

[0034] Such as Figure 1-4 As shown, a contact-free body fluid collection device includes a storage device 4, the front end of the storage device 4 is fixed with a chute 3, the upper end of the storage device 4 is connected with a fixed tube 2 through screw rotation, and the upper end of the fixed tube 2 is fixed with a package Device 1, the storage device 4 comprises a shell 43, the inner surface of the shell 43 is slidingly connected with a storage tube 44, the top of the storage tube 44 is fixed with a guide tube 45 at the inner position of the shell 43, and the inside of the storage tube 44 is connected by a threaded rotation. Fixed cover 42, the upper end of fixed cover 42 is fixed with connecting rod 41, and the upper end of connecting rod 41 is fixed with sealing cover 46, and preservation tube 44 comprises cylindrical body 442, and the lower end of cylindrical body 442 is connected with base plate 443 by screw thread rotation, and cylindrical body 442 A slider 441 is f...

Embodiment 3

[0037] Such as Figure 1-5As shown, a contact-free body fluid collection device includes a storage device 4, the front end of the storage device 4 is fixed with a chute 3, the upper end of the storage device 4 is connected with a fixed tube 2 through screw rotation, and the upper end of the fixed tube 2 is fixed with a package The device 1, the wrapping device 1 includes an inclined tube 11, the upper end of the inclined tube 11 is fixed with a shaping ring 12, and the upper end of the shaping ring 12 is fixed with an elastic ring 13.

[0038] When the wrapping device 1 is attached to the user's face, the elastic ring 13 is deformed and attached to the user's skin surface. The elastic ring 13 can reduce the extrusion of the shaping ring 12 on the skin surface, effectively protect the user's facial skin, and maintain the elasticity. The ring 13 fits on the face to prevent the saliva from contacting with the air, so as to prevent the user from feeling sick due to the emitted sme...

Abstract

The invention provides a contact-free body fluid collection device. The device comprises a storage device, wherein a sliding groove is fixed to the front end of the storage device; the upper end of the storage device is rotationally connected with a fixing pipe through threads; and a wrapping device is fixed to the upper end of the fixing pipe. According to the invention, a fixed cover can be stably driven to move through a sealing cover, and the fixed cover is fixed on the surface of a preservation tube, so the preservation tube is sealed; a sealed environment prevents external air from entering, and saliva can be completely preserved; and meanwhile, the sealing cover prevents the saliva from flowing out of the surface of the preservation tube, and it is guaranteed that a sample is complete.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a contact-free body fluid collection device and a method for using the device. Background technique [0002] The liquid in the human body is composed of water, inorganic salts and organic substances dissolved in water, collectively referred to as body fluid. Water is the main component of body fluid and the most abundant substance in the human body. Body fluid is widely distributed inside and outside the cells of the body. Intracellular fluid is the substance The main part of metabolism, extracellular fluid is the internal environment for the survival of each cell in the body. Maintaining the dynamic balance of body fluid volume, distribution and composition is a necessary condition for ensuring normal metabolism of cells and maintaining the physiological functions of various organs. The analysis of the components can judge the working conditions of various organs in the body, so a...
