It carries out that circumferential whole situation can be shown comprehensively；
7) it is that linear structure facilitates extraction sample line close to the sample line of exposed end；
8) dry sample line radial dimension is less than thief hole internal diameter, the sample line radial dimension under wet condition and sampling
Hole internal diameter is consistent, and it is larger can to ensure that the sample line in most of length will not be generated when being extracted with thief hole inner wall in this way
Frictional resistance, extraction are easier, and implantation hose will not act because of extraction and generate larger shift in position；
9) sample line combines twisting by high-tenacity fibre and sampling silk, that is, ensures that extraction process will not break easily, guaranteed suction
Attached enough sample liquids；Porous chemical fiber wire or cotton thread can be saturated with liquid by a large amount of micropores of micro-or nano size；
10) setting of elastic can ensure after sample line detaches, and the instant closure of springhole blocks the thief hole
Aperture prevents liquid reflux.

Specific implementation mode
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As shown in Figs 1-4, a kind of medical spiral core sampling pipe, including：It is implanted into hose 1, is implanted on the tube wall of hose 1 and is arranged
Have a helical structure thief hole 2, thief hole 2 along tube wall circumferentially around and along probe tube it is axially extending, be equipped with one in thief hole 2
2 one segment length of thief hole is stretched out at root sample line 4,4 both ends of sample line, and the both ends of implantation hose 1 are respectively to be implanted into end 5 and exposed
End 6, the extension that sample line 4 is located at implantation end 5 are sampling end 8, and the extension for being located at exposed end 6 is to extract end 7；
It is implanted into 1 outer wall of hose and is equipped with several sampling windows 3, sampling window 3 is connected to thief hole 2, and sample line 4 passes through sampling window
3 is exposed.
It is perforative in the tube wall of implantation hose 1 to be equipped with sample line 4, after it will be implanted into hose 1 and once be implanted into human body, it is not required to
Implantation hose 1 is moved, only need to extract sample line 4 can will be sampled the affected part in human body, then chemical examination detection, no
Secondary injury can be caused to affected part.
The pore that the inner wall of implantation hose 1 is formed can guide liquid to pass in and out human body, can be the entrance of drug, can also
It is the discharge of body fluid etc..
The case where taking-up of sample line 4 can obtain the body fluid sample in affected part at any time, and detection judges affected part immediately.
The setting of sampling window 3 contribute to it is flexible and convenient multiple positions are sampled, sampling it is more diversified, also more
Comprehensively.
The outer diameter of sample line 4 in dry conditions be less than 2 internal diameter of thief hole, the outer diameter of sample line 4 in a wetted condition with
2 internal diameter of thief hole is consistent.Dry 4 radial dimension of sample line is less than 2 internal diameter of thief hole, and the sample line 4 under wet condition is radial
Size is consistent with 2 internal diameter of thief hole, can ensure that the sample line 4 in most of length will not be with thief hole when being extracted in this way
2 inner walls generate larger frictional resistance, and extraction is easier, and implantation hose 1 will not act because of extraction and generate larger shift in position.
The aperture of thief hole 2 is sufficiently small compared with the aperture of pore, and the mobility of liquid inside it is limited.
Several sampling windows 3 are arranged one by one along the hand of spiral of thief hole 2.The sample line 4 of helical structure can be to implantation
Hose 1 is circumferential to be sampled per direction a one by one, and circumferential whole situation can be shown in circumferentially progress comprehensively by sampling.
Sample line 4 by least one high-tenacity fibre and at least one sampling silk is twisted is formed, high-tenacity fibre is made of chemical fibre, sampling
Silk is made of cotton thread or is made of porous chemical fiber wire.Sample line 4 combines twisting by high-tenacity fibre and sampling silk, that is, ensures extraction process
It will not break easily, the enough sample liquids of guaranteed absorption；Porous chemical fiber wire or cotton thread are by the big of micro-or nano size
Micropore is measured, liquid can be saturated with.
The thief hole 2 at nearly implantation end 5 is helical structure, close to 2 axis of thief hole and implantation 1 axis of hose of exposed end 6
Unanimously.Sample line 4 close to exposed end 6 is that linear structure facilitates extraction sample line 4.
The end at implantation end 5 is additionally provided with an elastic 9, and elastic 9 is corresponding with 2 orifice position of thief hole, on elastic 9
If there are one the springholes 10 being connected to thief hole 2.The setting of elastic 9 can ensure after sample line 4 detaches, springhole 10
Instant closure blocks the aperture of the thief hole 2, prevents liquid reflux.
In the use of the present invention, implantation end 5 is embedded in human body, exposed end 6 exposes human body and passes through pumping after a certain period of time
It takes a 7 piece sample line 4 of extraction of end and detects the sample liquids that laboratory sampling line 4 is taken out of.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
