Description

A kind of milch cow endometrial biopsy sampler

Technical field

This utility model belongs to the experimentation apparatus, particularly relates to a kind of for milch cow vagina and intrauterine sterile sampler.

Background technology

Milk cattle cultivating already is production project very important in the animal husbandry, and the development of animal husbandry is had very important meaning.The economic performance of milch cow has determined the importance of breeding for milch cow.The infertility of milch cow has already brought huge economic loss for milk cattle cultivating as one of milch cow four large class diseases, is worldwide economic problems.Endometritis is one of study hotspot of Chinese scholars as the one of the main reasons of barrenness of milk cow all the time.Make a general survey of many reports about the identical research direction of endometritis both at home and abroad, its result has certain difference, causes the reason of these differences to have a lot, and wherein research means is not both topmost reason.Whether the acquisition method of uterine bacteria sample science, and whether be related to the result of study that obtains credible, and different results of study can appear in different intrauterine sample collection methods.Therefore, the collection of intrauterine sample is the key link of endometritis research.

The acquisition method of intrauterine sample has a lot, as: utilize deferent duct to inject a certain amount of flushing liquor to intrauterine, and then reclaim flushing liquor; Perhaps utilize isolated uterine, although these methods can avoid polluting, can not the research trends Changing Pattern, and somewhat expensive; Not representative as sample with going out liquid, changed intrauterine environment because go out liquid, may be to the credibility of sample and the natural restoration of old ways process in uterus exert an influence next time.

Summary of the invention

This utility model provides a kind of milch cow endometrial biopsy sampler, to solve institute's collected specimens vulnerable to pollution of occurring in the sampling process, to be subject to the problem that alien bacteria infects by acquisition target uterus, vagina.

The technical scheme that this utility model is taked is: inner tube and outer tube socket, outer tube and overcoat socket, the outer tube end has the handle one of band indication breach, and the inner tube end has the handle two of band indication breach, the front end of inner tube has the cotton swab placing trough, and the front end of outer tube has the sampling groove.

The utility model has the advantage of: novel structure is simple, and is easy to operate, little to vulneratio uteri during sampling, and sampling is convenient, and is effective, can the repeated disinfection utilization, can repeatedly sample.

Description of drawings

Fig. 1 is the structural representation of this utility model sampling groove when opening;

Fig. 2 is the structural representation of this utility model sampling groove when closing.

The specific embodiment

Inner tube 2 and outer tube 1 socket, outer tube 1 and overcoat 3 sockets, outer tube 1 end has the handle 1 of band indication breach, and inner tube 2 ends have the handle 2 201 of band indication breach, and the front end of inner tube 2 has cotton swab placing trough 202, and the front end of outer tube 1 has sampling groove 102.

In use, with tweezers the sterile cotton swab is put into the cotton swab placing trough, rotate the handle two of band indication breach, make the breach opposite direction on two handles, the groove of sampling this moment is in closed condition.Hold the handle one of band indication breach sampler is sent into vagina, when front end arrives orifice of uterus, hold the handle one of band indication breach, outer tube is released forward from overcoat, be deep into intrauterine, the handle two of the terminal band indication of rotation inner tube breach, make the breach direction on two handles identical, this moment, the groove of sampling was in open mode, by the external use hands with Uterus wall by being pressed in the sampling groove on the cotton swab, contacted l minute, decontrol the right hand, Uterus wall is separated with the sampling groove, close the sampling groove, outer tube is return in the overcoat, together detached again vagina.Can not be subject to external source germ contamination when sample transcervical in transit, vagina, really accomplish farthest to guarantee the accuracy of intrauterine sampling.

Claims (1)

1. a milch cow endometrial biopsy sampler is characterized in that: inner tube and outer tube socket, outer tube and overcoat socket, the outer tube end has the handle one of band indication breach, the inner tube end has the handle two of band indication breach, and the front end of inner tube has the cotton swab placing trough, and the front end of outer tube has the sampling groove.
