Description

Technical Field

[0001] The utility model relates to the technical field of intrauterine fluid aspiration, and in particular to a non-invasive intrauterine fluid aspiration device. Background Art

[0002] At present, for patients with intrauterine fluid before embryo transfer in the reproductive center, intrauterine fluid aspiration treatment is mainly adopted. However, there is no special intrauterine fluid aspiration tube at present, and basically an artificial insemination tube is used to replace it to draw out the fluid.

[0003] However, the existing artificial insemination tube is not long enough. For patients who are obese, have obvious upward lifting of the cervix after cesarean section, and have a large uterine cavity, when using the artificial insemination tube to draw out the intrauterine fluid, the relative length is insufficient, and the fluid at the bottom of the uterine cavity cannot be aspirated cleanly, thus affecting the treatment effect. Moreover, the existing artificial insemination tube has insufficient strength and toughness, and there is no corresponding guiding structure at the end, resulting in large bending and concave situations at the cervix and deep vagina of the patient during actual use. Therefore, medical staff need to repeatedly insert and pull out the artificial insemination tube to insert it into the uterine cavity, and the repeated insertion and pulling out will cause discomfort to the patient, and there is room for improvement in terms of practicality.

A fluid drainage tube 300 is provided at the rear end of the connection seat 200. The length of the fluid drainage tube 300 is 15 cm. The fluid drainage tube 300 and the connection seat 200 are of an integrated structure. The fluid drainage tube 300 with a length of 15 cm can extend to the bottom of the uterine cavity to drain the fluid at the bottom of the uterine cavity of the patient. A length scale line 301 is provided on the circumferential side of the fluid drainage tube 300, and the length scale line 301 facilitates medical staff to observe the insertion depth of the fluid drainage tube 300, thereby conveniently judging the approximate position where the fluid drainage tube 300 is inserted into the patient's vagina. An anti-slip inner lining 201 is adhesively bonded to the circumferential side inside the connection seat 200, and the material of the anti-slip inner lining 201 is medical silicone rubber. The anti-slip inner lining 201 matches the inlet of the disposable aspirator 100. The anti-slip inner lining 201 made of medical silicone rubber makes the connection between the disposable aspirator 100 and the connection seat 200 more stable.

[0035] A strengthening component 400 is arranged inside the fluid drainage tube 300, and the strengthening component 400 is used to strengthen the strength of the fluid drainage tube 300. A guiding component 500 is arranged at the rear end of the fluid drainage tube 300, and the guiding component 500 is used to guide the inlet at the rear end of the fluid drainage tube 300. The material of the disposable aspirator 100 is a disposable syringe.

The plurality of strengthening inner rings 403 are arranged at equal intervals. The material of the strengthening inner rings 403 is the same as that of the fluid drainage tube 300. The fluid drainage tube 300 and the strengthening inner rings 403 are of an integrated structure. The plurality of strengthening inner rings 403 arranged at equal intervals can improve the strength and toughness of the fluid drainage tube 300, and avoid the situation that the fluid drainage tube 300 is easily bent or dented significantly during the insertion and use process.

[0037] A circular through-hole 405 is provided in the middle position inside the strengthening inner ring 403. The circular through-hole 405 facilitates the flow of accumulated fluid through the inside of the strengthening inner ring 403. A plurality of edge through-grooves 404 are provided at the edge of the strengthening inner ring 403, and the shape of the edge through-grooves 404 is U-shaped. The plurality of U-shaped edge through-grooves 404 facilitate the accumulated fluid on the inner wall of the accumulated fluid drainage tube 300 to flow through the strengthening inner ring 403, thereby ensuring the smooth drainage of the accumulated fluid drainage tube 300.

When the expansion piece 401 deforms during preheating, it will bend outward into an arc shape. The expansion piece 401 made of nitinol can automatically return to its original shape at a certain specific temperature. So that during the process of the expansion piece 401 being inside the patient's uterine cavity, it bends and deforms outward to jack up the uterine cavity wall attached to the outer surface of the introduction cavity 402 to separate it and generate a certain gap, avoiding the uterine cavity wall attaching to the outer surface of the introduction cavity 402 and causing the accumulated fluid to not flow smoothly.

[0038] In a further embodiment of the present utility model, by providing the support rod 502 and the reinforcing rib 503, the guiding head 501 can be stably supported, so that the guiding head 501 guides the rear end of the accumulated fluid drainage tube 300, making the accumulated fluid drainage tube 300 more smooth when extending into the patient's vagina and cervix. And the provided through-hole 504 facilitates the uterine cavity accumulated fluid to flow through the guiding head 501 and enter the accumulated fluid drainage tube 300.

[0039] The guiding assembly 500 includes a guiding head 501 and a support rod 502. A support rod 502 is provided at the rear end of the accumulated fluid drainage tube 300. The support rod 502 and the guiding head 501 and the accumulated fluid drainage tube 300 are of an integral structure. The support rod 502 can support the guiding head 501. A guiding head 501 is provided at the rear end of the support rod 502. The shape of the guiding head 501 is semi-circular. The semi-circular guiding head 501 is more smooth when inserted into the patient's vagina and cervix. The outer diameter of the guiding head 501 is larger than the outer diameter of the accumulated fluid drainage tube 300. The guiding head 501 with an outer diameter larger than the outer diameter of the accumulated fluid drainage tube 300 can guide the accumulated fluid drainage tube 300, so that the accumulated fluid drainage tube 300 is more smooth when inserted into the patient's vagina and cervix. A reinforcing rib 503 is provided inside the support rod 502. The reinforcing rib 503 makes the support rod 502 have better strength, avoiding the support rod 502 from being easily bent and deformed during use. A through-hole 504 is provided inside the guiding head 501, and the inner diameter of the through-hole 504 is the same as the inner diameter of the accumulated fluid drainage tube 300. The through-hole 504 facilitates the uterine cavity accumulated fluid to flow through the inside of the guiding head 501.

[0040] Working principle: When performing non-invasive aspiration of intrauterine fluid on a patient, medical staff first insert the unused fluid drainage tube 300 into the patient's vagina and continuously extend it backward. During this process, the guiding head 501 guides the rear end of the fluid drainage tube 300, and multiple equally spaced reinforcing inner rings 403 can improve the strength and toughness of the fluid drainage tube 300, preventing the fluid drainage tube 300 from being easily bent or indented significantly during the insertion process, so that the fluid drainage tube 300 can be inserted more smoothly through the patient's vagina and cervix. And medical staff can judge the insertion depth of the fluid drainage tube 300 only by observing the length scale line 301; when the fluid drainage tube 300 is inserted to the required depth inside the patient's uterine cavity, the insertion is stopped. At this time, the inlet of the unused disposable aspirator 100 is snap-connected to the connection seat 200, so that medical staff can use the disposable aspirator 100 and the fluid drainage tube 300 to aspirate the fluid inside the patient's uterine cavity. During this process, the fluid inside the patient's uterine cavity will flow into the fluid drainage tube 300 through the through holes 504, the introduction cavity 402, and the gap between the guiding head 501 and the fluid drainage tube 300 respectively. Then, the disposable aspirator 100 sucks out the fluid flowing into the fluid drainage tube 300. And during the process of the expansion piece 401 made of nitinol alloy being inside the patient's uterine cavity, the heat inside the uterine cavity will cause the expansion piece 401 to bend outward and deform to lift the uterine wall fitting on the outer surface of the introduction cavity 402 to separate it and generate a certain gap, preventing the uterine wall from fitting on the outer surface of the introduction cavity 402 and causing the fluid to not flow smoothly into the introduction cavity 402. The circular through hole 405 and the edge through groove 404 facilitate the fluid flowing into the fluid drainage tube 300 to flow through the reinforcing inner ring 403, preventing the reinforcing inner ring 403 from obstructing the fluid flow inside the fluid drainage tube 300. When all the intrauterine fluid of the patient is aspirated, medical staff only need to slowly pull out the fluid drainage tube 300 and remove it from the patient's vagina.

[0041] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
