Description
Technical field
The present invention relates to a kind of detection means, more particularly to a kind of disposable intestinal canal tumour examination detection sleeve pipe.
Background technology
It is known that existing tumor in digestive tract fecal acquisition testing method is using cotton swab hand-manipulated or small modeling
Charge bar is dipped, gathers some excrement, then excrement is put into small plastic cup or test tube, then is examined to being added in small plastic cup or test tube
Test agent, and make excrement mix with reagent, then carries out result judgement, enters that row information is filled in a form, information collects successively again afterwards
The work such as report.The detection method flow is cumbersome, wastes time and energy, during the preparation manipulation of sample, reagent and sample always with ring
Border air is in open intercommunication state, has not only easily polluted environment but also influence, and this detection are easily produced on the validity of sample
Can be carried out in the medical institutions of specialty, it is difficult to carry out large-scale popularization and application.
The content of the invention
The present invention is cumbersome for existing tumor in digestive tract fecal acquisition testing method flow, wastes time and energy, sample
During preparation manipulation, reagent is in open intercommunication state with surrounding air always with sample, has not only easily polluted environment but also easily to sample
This validity is produced to be influenceed, and this detection can only be carried out in the medical institutions of specialty, it is difficult to promoted on a large scale
The technical problem of application, there is provided a kind of flow is simple, time saving and energy saving, during the preparation manipulation of sample, reagent will not with sample
Open intercommunication state is in surrounding air, it is not only free from environmental pollution but also influence will not be produced on the validity of sample, can not only be
The medical institutions of specialty are carried out, it is also possible to carry out the tumor in digestive tract fecal acquisition testing set of large-scale popularization and application
Dress.
Therefore, a kind of disposable intestinal canal tumour examination detection sleeve pipe of the present invention, is provided with shell and excrement sampling core body, excrement
Sampling core body includes outer tube, is provided with lancet in the middle of outer tube, and outer tube is provided with outer tube connection end close to upper end surface, case nose with
Outer tube connection end connects, and shell inner cavity body lower end is provided with reactant cavity, is provided with developer cavity side by side with reactant cavity, instead
Answer and barrier film is provided between agent cavity and developer cavity, developer cavity upper end is provided with diaphragm seal.
Preferably, reactant cavity is located at developer cavity upper end, and reactant cavity upper end is provided with diaphragm seal.
Preferably, lancet upper end is provided with press-in face, and press-in face forms a feces collection storage cavity with outer tube wall.
The beneficial effects of the invention are as follows due to being provided with shell and excrement sampling core body, excrement sampling core body includes outer tube, outward
Pipe is provided with outer tube connection end close to upper end surface, and case nose is connected with outer tube connection end, and shell inner cavity body lower end is provided with reaction
Agent cavity, developer cavity is provided with reactant cavity side by side, and barrier film is provided between reactant cavity and developer cavity, is shown
Toner cavity upper end is provided with diaphragm seal, when in use, excrement sampling core body is removed, and gathers some excrement, then adopts excrement
Sample core body and cage connection, the lancet being provided with the middle of outer tube wear out diaphragm seal and barrier film, by excrement and reactant cavity and
Reagent mixing in developer cavity, and reacts, and measures result, during the preparation manipulation of whole sample, reagent and sample
Product will not be in open intercommunication state with surrounding air, and flow is simple, time saving and energy saving, not only free from environmental pollution but also will not be to sample
Validity produces influence, can not only be carried out in the medical institutions of specialty, it is also possible to carry out large-scale popularization and application.

Specific embodiment
The present invention is described further with reference to embodiment.
As Figure 1-3, it is a kind of disposable intestinal canal tumour examination detection sleeve pipe of the present invention, is provided with shell 1 and excrement is adopted
Sample core body 2, excrement sampling core body 2 includes outer tube 3, and lancet 4 is provided with the middle of outer tube 3, and outer tube 3 is provided with outer tube close to upper end surface
Connection end 5, the front end of shell 1 is connected with outer tube connection end 5, and the inner chamber body lower end of shell 1 is provided with reactant cavity 14, with reactant chamber
Body 14 is provided with developer cavity 15 side by side, and barrier film 16, developer chamber are provided between reactant cavity 14 and developer cavity 15
The upper end of body 15 is provided with diaphragm seal 11.
When in use, excrement sampling core body is removed, gathers some excrement, then connect excrement sampling core body 2 with shell 1
Connect, the lancet 4 being provided with the middle of outer tube 3 wears out diaphragm seal 11 and barrier film 16, by excrement and reactant cavity 14 and developer
Reagent mixing in cavity 15, and react, result is measured, during the preparation manipulation of whole sample, reagent is with sample not
