Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to an ovarian follicle aspiration auxiliary device. BACKGROUND

[0002] Oocyte retrieval surgery is a surgical operation to take out the ovum, which is mainly used for infertile women who choose to have a test-tube baby pregnancy and patients who need to freeze the ovum due to medical indications. The most common oocyte retrieval method is to guide the oocyte retrieval needle through the vaginal vault to the ovary under the guidance of transvaginal B-ultrasound, puncture the ovarian follicle, and suck out the follicular fluid and ovum.

[0003] In the oocyte retrieval operation, B-ultrasound monitoring ovulation can effectively monitor the number, position and development process of the dominant follicle, and locate the ovum. Therefore, the doctor needs to locate the ovum by observing the B-ultrasound during the entire extraction process. In actual operation, the needle tip of the extraction device may come into contact with the follicle wall during extraction, causing extraction blockage, and the extraction position may be incorrect during extraction, causing blood to be extracted. The mixing of blood not only affects the smoothness of follicular fluid outflow and the color of the collected follicular fluid, but also increases the difficulty of oocyte retrieval in the laboratory. Generally, the nurse will assist in observation and pass the above information to the doctor. However, since the nurse has other responsibilities, the nurse will not always read out the above information to the doctor in actual operation, and the doctor still needs to look back. On the one hand, the doctor cannot timely discover the above problems and make adjustments, and on the other hand, when the doctor looks back, the hand may move at the same time, causing the puncture position to change and increasing the possibility of puncture position error.

[0030] The flow diversion assembly 1 comprises a three-way valve 11, a flow diversion conduit 13, a drainage bag 14 and a one-way valve 12 for controlling the one-way flow of liquid to the drainage bag 14; the three-way valve 11 comprises a first liquid outlet interface 111, a second liquid outlet interface 112 and a liquid inlet interface 113, the one-way valve 12 is installed on the liquid inlet interface 113, and the drainage bag 14 is connected with the one-way valve 12 through the flow diversion conduit 13; the first conduit 21 is connected with the first liquid outlet interface 111, and the second conduit 33 is connected with the second liquid outlet interface 112.

[0031] In order to facilitate the connection of the color warning assembly 2 and the flow rate monitoring assembly 3 with the follicular fluid collection and follicular fluid extraction device, the active end of the first conduit 21 and the third conduit 34 is respectively fixedly provided with an adapter 4. Preferably, the adapter 4 is connected with a short inner diameter larger than a general medical conduit, and further, in order to increase the connection adaptability of the adapter 4, a clasp 41 for adjusting the connection tightness is fixedly sleeved on the peripheral wall of the adapter 4, so as to facilitate the connection of the adapter 4 with the medical conduit.

[0032] The inner side walls of the effusion dropper 32 are symmetrically provided with guide sliding grooves 323 along the height direction thereof, and the floating plate 321 is provided with guide sliding blocks 3214 on the sides corresponding to the guide sliding grooves 323, so as to guide the up and down movement of the floating plate 321 and avoid the rotation of the floating plate 321 during the floating process, and facilitate the induction between the infrared light lamp 3212 and the first inductor 311.

[0033] Further, the warning sleeve 22 and the fixed shell 31 are respectively provided with a power supply 5 for providing electric energy.

[0034] The working principle is roughly as follows:

[0035] Before operation, the nurse connects the first catheter 21 with the catheter of the follicular fluid extraction device, and connects the third catheter 34 with the catheter of the follicular fluid collection device. In the initial state, the first catheter 21 is connected with the second catheter 33 through the three-way valve 11. When the doctor extracts the follicular fluid, the follicular fluid is extracted and passes through the first catheter 21, the warning collar 22, the three-way valve 11, the second catheter 33, the fixed shell 31, and the third catheter 34 in turn. When the follicular fluid passes through the warning collar 22, the inner wall light lamp 221 of the warning collar 22 irradiates the catheter and transmits the color of the follicular fluid passing through the catheter to the outside through the light-transmitting mirror 223. If blood is extracted when the follicular fluid is extracted, the light lamp 221 will map out a red light to the outside through the catheter, which is convenient for the doctor and the nurse to find out in time. At this time, the three-way valve 11 can be rotated to connect the first catheter 21 with the drainage bag 14, so as to collect the blood in the drainage bag 14 (in addition to blood, part of the fallopian tube fluid, ovarian cyst puncture fluid, etc. may also be separated during the drainage process. In order to avoid omission, the drainage bag 14 can be sent for inspection), so as to avoid the accumulation of blood in the follicular fluid collection device as much as possible. When the doctor adjusts the extraction angle and extracts clear follicular fluid again, the three-way valve 11 is rotated to connect the first catheter 21 with the second catheter 33.

[0036] When the follicular fluid passes through the fixed shell 31, the inner diameter of the third catheter 34 is smaller than that of the second catheter 33, so the speed of the follicular fluid flowing into the fluid drop tube 32 is greater than the speed of the follicular fluid flowing out. A certain amount of follicular fluid is accumulated in the fluid drop tube 32. Under normal circumstances, the infrared light lamp 3212 on the outer side wall of the floating plate 321 is below the first inductor 311, and the inductive chip 3213 at the bottom of the floating plate 321 is away from the second inductor 322. When there is a blockage problem in follicular fluid extraction, the speed of the follicular fluid flowing into the fluid drop tube 32 is less than the speed of the follicular fluid flowing out, so that the amount of follicular fluid in the fluid drop tube 32 decreases, the position of the floating plate 321 drops, the inductive chip 3213 at the bottom of the floating plate 321 contacts and senses the second inductor 322. The second inductor 322 outputs a signal to the alarm sound 312, so that the alarm sound 312 alarms, so that the doctor can find out in time. When the follicular fluid extraction device extracts normally, and the catheter of the follicular fluid collection device is blocked or the collection device is full and not replaced, the speed of the follicular fluid flowing into the fluid drop tube 32 is greater than the speed of the follicular fluid flowing out, so that the amount of follicular fluid in the fluid drop tube 32 increases, and the infrared light lamp 3212 on the outer side wall of the floating plate 321 irradiates and senses the first inductor 311. The first inductor 311 outputs a signal to the alarm sound 312, so that the alarm sound 312 alarms, so that the doctor can find out the problem in time.

[0037] The above merely describes a specific implementation of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct or indirect application in other related technical fields using the content of the present application specification and drawings are also included in the patent protection scope of the present application.
