Description
Technical field
The invention belongs to herding the field of medical instrument technology, more particularly to a kind of cattle uterus epithelial cell sampler.
Background technology
The heavy livestocks such as ox often will appear the illnesss such as uterus illness, especially endometritis, but endometritis etc.
Illness is often not easy to judge, it usually needs acquisition uterine epithelial cell is detected, and is then made for illness and being controlled accordingly
It treats.Due to the uterine neck stenostomia of cattle uterus and very deep, cause the sampling difficulty for acquiring uterine epithelial cell big.Existing cattle uterus
Epithelial cell sampler is mostly simple in structure, and collection capacity is small, acquisition position is not comprehensive, and effect is poor, and takes out instrument after sampling
During hiding ball top during device or by casing, easily the epithelial cell acquired is scratched again and is come off.

The sampling rack that the front center of pushing ram is provided symmetrically, the sampling rack include the linkage section being connect with pushing ram front end,
The folding and unfolding section that connect with linkage section front end and dehisce in the gradual forward end of splayed configuration and the arc sampling for being connected to folding and unfolding section front end
Section, the outside of arc sampling section are equipped with sampling fiber, and the front end of arc sampling section is connected with taper guide head；Outer tube is by nearby
The inner tubal wall at end is equipped with annular protrusion.
Preferably, inner tubal wall of the outer tube close to rear end is equipped with positioning ring groove, and the outer wall of pushing ram is along the circumferential direction
The uniformly distributed locating slot that several are radially set, positioning trench bottom are equipped with retaining spring, and retaining spring is equipped with locking ball.
Preferably, the front end of the arc sampling section of the sampling rack is connected to the center of taper guide head, another
Arc sampling Duan Weiyu tapers guide head connection.
Preferably, the cattle uterus epithelial cell sampler is equipped with one end open, and the other end is cecum, and inner cavity is led with taper
To head and the matched protective case of outer tube.
The beneficial effects of the invention are as follows：
The sampling rack of the cattle uterus epithelial cell sampler of the present invention is equipped with folding and unfolding section and annular protrusion, passes through annular protrusion
Folding and unfolding section is squeezed, arc sampling section is made to close up to center, during taking out instrument after sampling, reduces the epithelial cell quilt of acquisition
It scratches and comes off.

Specific embodiment
Embodiment one：Referring to Fig. 1-2, a kind of cattle uterus epithelial cell sampler including handle 1 and is located at 1 front end of handle
Pushing ram 2, the outer wall of pushing ram 2 is arranged with that outer tube 3, the front center of pushing ram 2 are equipped in axial sliding along pushing ram 2
Symmetrically arranged sampling rack 4, sampling rack 4 include the linkage section 41 that is connect with 2 front end of pushing ram, connect with 41 front end of linkage section and
The folding and unfolding section 42 dehisced in the gradual forward end of splayed configuration and the arc sampling section 43 for being connected to 42 front end of folding and unfolding section, arc sampling section
43 outside is equipped with sampling fiber 44, and the front end of arc sampling section 43 is connected with taper guide head 5.Outer tube 3 is by front end
Inner tubal wall is equipped with annular protrusion 32.
Inner tubal wall of the outer tube 3 close to rear end is equipped with positioning ring groove 31, and the outer wall of pushing ram 2 is along the circumferential direction uniformly distributed several
The locating slot 21 of a radial direction setting, 21 bottom of locating slot are equipped with retaining spring 7, and retaining spring 7 is equipped with locking ball 6.
Cattle uterus epithelial cell sampler is equipped with one end open, and the other end is cecum, inner cavity and taper guide head 5 and housing
3 matched protective case of pipe（It is not drawn into figure）.The cecum of protective case can be made by the material being more easily damaged, and protective case is ox
Uterine epithelial cell sampler, which provides, cleans sterile environment, while reduces cattle uterus epithelial cell sampler and transporting or storing
The risk for being polluted or being destroyed in the process.
In use, the protective case of cattle uterus epithelial cell sampler is removed to or utilized taper guide head 5 by protective case
Cecum puncture, outer tube 3 is pushed along 2 forward end of pushing ram, annular protrusion 32 gradually squeezes folding and unfolding section 42, folding and unfolding section 42
Splayed configuration dehisces gradually to center to close up, and folding and unfolding section 42 drives arc sampling section 43 to close up to center, when outer tube 3 is pushed into determine
When position annular groove 31 reaches the locating slot 21 of pushing ram 2, a part for locking ball 6 is pressed into positioning ring groove 31 by retaining spring 7, this
When arc sampling section 43 close up to minimum state, the diameter of the circumference where the outermost of arc sampling section 43 is less than outer tube 3
Outer diameter.Then cattle uterus epithelial cell sampler is placed in the designated position of cattle uterus, by outer tube 3 along pushing ram 2 backward
End pushes, and positioning ring groove 31 leaves locating slot 21, and folding and unfolding section 42 gradually breaks away from the extruding of annular protrusion 32, eight words of folding and unfolding section 42
Type dehisces gradually to be flared out, and folding and unfolding section 42 drives arc to sample section 43 to being gradually flared out, rotation handle 1,1 band of handle
Dynamic pushing ram 2 rotates, and pushing ram 2 drives sampling rack 4 to rotate, and the sampling fiber 44 in arc sampling section 43 acquires cattle uterus epithelium
Cell.
After the completion of acquisition, outer tube 3 is pushed along 2 forward end of pushing ram, annular protrusion 32 gradually squeezes folding and unfolding section 42, receives
It puts the splayed configuration of section 42 to dehisce gradually to center to close up, folding and unfolding section 42 drives arc sampling section 43 to center to close up, and works as housing
When pipe 3 is pushed into the locating slot 21 of the arrival pushing ram 2 of positioning ring groove 31, retaining spring 7 positions the part press-in of locking ball 6
Annular groove 31, at this time arc sampling section 43 close up to minimum state, the diameter of the circumference where the outermost of arc sampling section 43 is small
In the outer diameter of outer tube 3.Since the diameter of the circumference where the outermost of arc sampling section 43 is less than the outer diameter of outer tube 3, take
During going out cattle uterus epithelial cell sampler, it is possible to reduce the epithelial cell of acquisition is scratched the quantity to come off, while
Intrauterine tissue can be damaged to avoid prominent sampling section 43.
Embodiment two：Referring to Fig. 3, embodiment two and embodiment one are essentially identical, and something in common repeats no more, difference
It is：The front end of the arc sampling section 43 of sampling rack 4 is connected to the center of taper guide head 5, another arc sampling section 43
It is not connect with taper guide head 5.Outer diameter bigger when the two arcs sampling section 43 of such design is opened completely again, increases acquisition
Working space, collection effect are more preferable.
