Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] Such as figure 1 , figure 2 , image 3 As shown, the disposable transport sampler includes a liquid holding tube 1, a connection fixing plug 2, a swab 3 and a test tube 4, the liquid holding tube 1 is equipped with a nutrient solution, and the nozzle 11 of the liquid holding tube 1 is sealed and connected to the connection and fixed On the outer wall of the upper end of the plug 2, the swab 3 fixed at the lower end of the connecting fixed plug extends into the bottom of the inner cavity of the test tube 4, and the lower end of the connecting fixed plug 2 is connected with the test tube 4. The inside of the rod of the swab 3 is a hollow pipe, inside the connecting fixed plug 2 There is a sealing film 21 in the through hole, and the puncture rod 5 is arranged on the upper end of the sealing film 21 in the through hole. Composed of compressible telescopic tubes, the...

Abstract

The invention discloses a one-time conveying sampler. The one-time conveying sampler comprises a liquid accommodation pipe, a connection and fixing plug, a swab and a test tube; nutrient solution is filled in the liquid accommodation pipe; the liquid accommodation pipe is hermetically sleeved on the outer wall of the upper end of the connection and fixing plug; the lower end of the connection and fixing plug is connected with the test tube; a hollow pipeline is arranged in a swab rod; a sealing membrane is arranged in a through hole in the connection and fixing plug; a puncturing lever is arranged at the upper end of the sealing membrane in the through hole; the outer wall of the puncturing lever is provided with a flow guide groove; the liquid accommodation pipe is provided with a soft rubber key which consists of a plurality of telescopic pipes and is used for pressing the top of the liquid accommodation pipe; and after the soft rubber key in the middle of the liquid accommodation pipe is compressed, the top of the liquid accommodation pipe props the top of the puncturing lever, the puncturing lever is stressed to press and poke the sealing membrane, and the nutrient solution in the liquid accommodation pipe flows into the through hole of the connection and fixing plug along the flow guide groove of the outer wall of the puncturing lever and then flows to a swab head below along the hollow pipeline of the swab rod so as to store the acquired sample.

Description

technical field [0001] The invention relates to a medical or microbiological analysis device, a device for collecting and storing biological samples, in particular to a disposable transport sampler. Background technique [0002] At present, the swab collector can integrate sampling, transfer, storage and sample pretreatment, which can reduce the pollution in multiple links from sample collection to sample processing, and ensure that the samples are effectively protected and cultivated before analysis. Authenticity and reliability provide favorable guarantees. The structure of the existing swab collector is to use the fixed plug to drive the swab head for sample sampling. The swab after sampling is placed vertically in the test tube. Since the liquid holding tube is a soft rubber tube, the plug on the fixed plug can be inferred directly with the thumb. Rod, the stopper rod breaks away from the fixed plug to produce a through hole, and the nutrient solution in the liquid hold...
