Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of intrauterine collection, and specifically to an apparatus for collecting microbial samples and endometrial specimens in the uterine cavity. Background Technique
[0002] The uterine cavity is the space of the uterus, also known as the uterus. The uterus is located in the center of the pelvic cavity and is in an anteverted and anteflexed position within the pelvic cavity. The flora in the uterine cavity can be divided into normal symbiotic flora and pathogenic abnormal flora. The abnormal flora may cause inflammation and damage to the endometrial function, thus directly affecting the physical and mental health of women.
[0003] Regarding the collection of intrauterine microbial samples, there are many existing techniques, for example:
[0004] Chinese Patent Publication No. CN217219079U discloses an apparatus for collecting microbial samples and endometrial specimens in the uterine cavity, including: an outer catheter, a sealing plug slidably sleeved on the outer catheter and sealingly connected to the outer peripheral surface of the outer catheter, a support member including a handle received in the outer catheter and a support frame connected to the end of the handle, the support frame being capable of expanding or contracting radially along the outer catheter, the handle being capable of moving axially in the outer catheter to push the support frame out of the outer catheter or retract the support frame into the outer catheter, and an inner catheter penetrating the outer catheter axially along the outer catheter.
[0005] Most apparatuses for collecting microbial samples and endometrial specimens in the uterine cavity include an outer catheter. By arranging an inner catheter penetrating the outer catheter in the outer catheter, the inner catheter is pushed to collect intrauterine microorganisms to obtain microbial samples at multiple sites. However, when sampling the uterine cavity inner wall, most use curettage means to obtain tissue samples of the uterine cavity inner wall. The several sampling small holes provided at the collection end of the inner catheter have poor curettage effect on the uterine cavity inner wall, and the obtained samples are few. At the same time, during the movement, the samples collected through the sampling small holes may also fall from the sampling small holes, resulting in sample contamination.
[0006] In view of this, we propose an apparatus for collecting microbial samples and endometrial specimens in the uterine cavity. Content of the Utility Model
[0007] The purpose of the present utility model is to provide an apparatus for collecting microbial samples and endometrial specimens in the uterine cavity that is convenient for curettage treatment and makes the obtained samples not easy to fall during the movement, so as to solve the problems raised in the above background technique.
[0008] To achieve the above purpose, the present utility model provides the following technical solutions:
[0009] A device for collecting intrauterine microbial samples and endometrial specimens comprises an outer sleeve, an inner sleeve and a sampler, wherein the sampler, the inner sleeve and the outer sleeve are connected in sequence, one end of the sampler is provided with a sampling end, the sampling end is provided with a plurality of sampling ears, and one side of the sampling ears is provided with an opening for performing curettage.
[0010] As a further solution of the utility model: one end of the inner sleeve is provided with a limiting ring for limiting the moving distance of the inner sleeve in the outer sleeve, and the end of the inner sleeve away from the limiting ring is provided with a support structure for opening the cervical opening.
[0011] As a further solution of the utility model: the support structure includes a plurality of rubber-coated layers, and an elastic steel sheet is arranged inside the rubber-coated layers. One end of the elastic steel sheet is fixed to one end of the inner sleeve.
[0012] As a further solution of the utility model: the rubber coating is equidistantly enclosed into a tubular shape with the center of the pipe opening of the inner sleeve as the center, and the diameter of the tubular shape formed by the rubber coating is smaller than the inner diameter of the outer sleeve.
[0013] As a further solution of the utility model: the sampler includes a tube body, an end of the tube body away from the sampling end is provided with a handle, and a hand guard is provided on the side of the handle close to the sampling end.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In the intrauterine microbial sample and endometrial specimen collection device, a sampling end is arranged at one end of the sampler, a plurality of sampling ears are arranged at the sampling end, and an opening for curettage is opened on one side of the sampling ear. When the sampling end of the sampler is inserted into the uterine cavity, the sampler is rotated in a clockwise and counterclockwise manner, so that the sampler can be rotated clockwise to scrape the endometrium through the sampling ears, and the sampler can be rotated counterclockwise to be pulled out, and the sample in the sampling ears can be protected from falling during the movement, thereby ensuring the safety of the sample during collection and transportation.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0025] As Figure 1 shown, this embodiment provides a device for collecting intrauterine microbial samples and endometrial specimens, including an outer sleeve 100, an inner sleeve 200, and a sampler 300. The sampler 300, the inner sleeve 200, and the outer sleeve 100 are sleeved in sequence. Considering the sampling of intrauterine microbial samples, therefore, one end of the sampler 300 is provided with a sampling end 304. Considering avoiding the dropping of microbial samples during movement, therefore, the sampling end 304 is provided with a plurality of sampling ear openings 305, and one side of the sampling ear openings 305 is provided with an opening for scraping the endometrium.
[0026] The improvement of this embodiment lies in: by setting a sampling end 304 at one end of the sampler 300, and setting a plurality of sampling ear openings 305 at the sampling end 304, and an opening for scraping the endometrium is opened on one side of the sampling ear openings 305. When the sampling end 304 of the sampler 300 is inserted into the uterine cavity, the sampler 300 is rotated in a clockwise and counterclockwise manner. Rotating the sampler 300 clockwise can scrape the endometrium through the sampling ear openings 305 and gradually squeeze and stack the samples in the sampling ear openings 305. When rotating counterclockwise and pulling out the sampler 300, the samples in the sampling ear openings 305 will not fall during the movement, ensuring the safety of the samples during collection and transportation.
[0027] As Figure 2As shown, taking into account the movement limit of the inner sleeve 200, one end of the inner sleeve 200 is provided with a limit ring 201 for limiting the moving distance of the inner sleeve 200 in the outer sleeve 100, and the end of the inner sleeve 200 away from the limit ring 201 is provided with a support structure 202 for opening the cervical opening. When the limit ring 201 is against one end of the outer sleeve 100, the support structure 202 protrudes from the outer sleeve 100 and fully opens, thereby expanding the cervical opening, making it convenient for the sampler 300 to be inserted from the tube of the inner sleeve 200 into the cervix, and the sampler 300 can penetrate into the uterine cavity for curettage.
[0028] like Figure 3 As shown, considering that the inner wall of the uterine cavity is composed of muscle tissue, in order to avoid scratching the inner wall of the uterine cavity when the expansion structure 202 is opened, the expansion structure 202 includes a plurality of rubber layers 203, and an elastic steel sheet 204 is arranged in the rubber layer 203. One end of the elastic steel sheet 204 is fixed to one end of the inner sleeve 200. The opening function of the expansion structure 202 is ensured by the elastic steel sheet 204. The elastic steel sheet 204 is arranged in the rubber layer 203, and the uterine cavity is prevented from being scratched. The inner wall is scratched by the elastic steel sheet 204. At the same time, considering the convenience of pulling out and pushing the inner sleeve 200, the rubber layer 203 is equidistantly enclosed into a tubular shape with the center of the pipe mouth of the inner sleeve 200 as the center. The diameter of the tubular shape formed by the rubber layer 203 is smaller than the inner diameter of the outer sleeve 100. When the inner sleeve 200 is pulled out, the support structure 202 is closed through the pipe mouth of the outer sleeve 100, and finally closed into a tubular shape, thereby facilitating the inner sleeve 200 to be pulled out from the outer sleeve 100.
[0029] like Figure 4 As shown, in order to prevent the sampler 300 from moving too deep in the inner sleeve 200, causing the tip of the sampling end 304 to poke the top of the uterine cavity and cause pain to the patient, the sampler 300 includes a tube body 301, and a handle 302 is provided at the end of the tube body 301 away from the sampling end 304, and a hand guard 303 is provided on the side of the handle 302 close to the sampling end 304. When the hand guard 303 is against the limiting ring 201 of the inner sleeve 200, the sampler 300 is extended into the uterine cavity through the inner sleeve 200 to reach the maximum length of the sampler 300, thereby preventing the tip of the sampling end 304 from poking the top of the uterine cavity.
[0030] In summary, the working principle of this scheme is as follows:
[0031] After inserting the outer sheath 100 into the cervical orifice, close one end of the expanding structure 202 of the inner sheath 200 and insert it into the outer sheath 100 until the limiting ring 201 on the inner sheath 200 abuts against one end orifice of the outer sheath 100. At this time, since the expanding structure 202 is not restricted by the outer sheath 100 and is affected by the elastic steel sheet 204, the expanding structure 202 fully expands, thus expanding the internal orifice of the uterine cavity. Insert the sampling end 304 of the sampler 300 into the inner sheath 200 until the hand guard 303 of the sampler 300 abuts against the limiting ring 201 of the inner sheath 200. At this time, the sampling end 304 is inserted into the uterine cavity. Rotate the handle 302 clockwise so that the sampling ear orifice 305 of the sampling end 304 scrapes the inner wall of the uterine cavity through the opening of the sampling ear orifice 305, thereby scraping the microbial sample into the sampling ear orifice 305. Rotate counterclockwise and synchronously withdraw the sampler 300, and use the shape of the sampling ear orifice 305 to reduce the dropping of the microbial sample, thus completing the sample collection.
[0032] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0033] Therefore, the above description is only a preferred embodiment of the present application and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
