Description

Technical Field

[0001] The invention belongs to the technical field of artificial insemination devices, and in particular relates to an artificial insemination device for assisted reproductive technology. Background Art

[0002] Artificial insemination is an assisted reproductive technology that delivers male sperm directly into the female reproductive tract through non-sexual intercourse, usually during the woman's ovulation period, to promote the natural combination and conception of sperm and egg.

[0003] During artificial insemination, a catheter needs to be inserted into the uterine cavity through the vagina and cervix, and then sperm is injected so that the sperm is injected into the uterine cavity through the sperm injection hole opened at the front end of the catheter. The sperm injection hole opened at the front end of the catheter of the existing artificial insemination device is in a normally open state. When the catheter passes through the vagina and cervix, secretions will enter the interior of the catheter through the sperm injection hole, so that when the sperm is injected, the vaginal secretions will be injected into the uterine cavity, which poses certain health risks, and the secretions may block the sperm injection hole, thereby causing sperm injection failure, and the catheter needs to be replaced, which is very troublesome, so it needs to be improved.

[0010] Preferably, a support plate is fixedly sleeved on the right side of the outer surface of the injection barrel, a rubber plug is movably sleeved inside the injection barrel, and a piston handle is fixedly connected to the right side of the rubber plug.

[0011] Preferably, a button is fixedly installed on the right side of the piston handle, and a fixing groove is provided at the bottom of the piston handle.

[0012] Preferably, a mounting box is fixedly installed at the bottom of the right side of the injection cylinder, and a bevel block is movably sleeved inside the mounting box.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention provides a first sperm injection hole, a movable plate, an inner catheter and a second sperm injection hole. When the first sperm injection hole and the second sperm injection hole are staggered, the inner catheter will close the first sperm injection hole, so that secretions cannot enter the interior of the inner catheter through the first sperm injection hole, thereby improving hygiene and safety while also avoiding the clogging of the first sperm injection hole by secretions. When the operator inserts the outer catheter into the uterine cavity, the push rod can be pushed to drive the movable plate to rotate. At this time, the movable plate will drive the inner catheter to rotate, so that the first sperm injection hole coincides with the second sperm injection hole, and then sperm can be injected into the uterine cavity through the first sperm injection hole and the second sperm injection hole.

[0015] 2. The present invention sets a slot, an annular block, a rectangular block and a push plate. The operator aligns the injection tube with the inner fixed frame and then inserts the injection tube into the inner catheter through the inner fixed frame. At this time, the annular block will be inserted into the outer fixed frame, so that the rectangular block enters the slot. The operator then rotates the injection barrel so that the annular block drives the rectangular block to rotate, thereby engaging the rectangular block with the slot. At this time, the fixed spring will push the push plate to the right under the action of elastic recovery, so that the push plate pushes the annular block to the right, thereby making the rectangular block fit more closely with the anti-slip pad and preventing the rectangular block from rotating. This makes the outer catheter as a whole and the injection barrel as a whole more firmly connected, thereby preventing the outer catheter as a whole from being separated from the injection barrel when the injection pressure is too high.

[0016] 3. The present invention provides a piston handle, a fixed groove and an inclined block, so that the operator can inject sperm by pushing the hand to the left. When the hand drives the piston handle to move to the left, the inner surface of the fixed groove will squeeze and push the inclined surface of the inclined block, so that the inclined block moves downward, and then the piston handle can move smoothly to the left. When the inclined block is located inside the fixed groove, the piston handle will not be able to move to the right, thereby limiting the piston handle in one direction and preventing the internal pressure of the injection barrel from being too high and pushing the piston handle to rebound to the right.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 12As shown, an embodiment of the present invention provides an artificial insemination device for assisted reproductive technology, comprising an outer catheter 1, a first sperm injection hole 2 is provided on the left side of the outer surface of the outer catheter 1, a fixed plate 3 is fixedly sleeved on the right side of the outer surface of the outer catheter 1, a movable plate 4 is movably sleeved inside the fixed plate 3, an inner catheter 5 is fixedly connected to the left side of the movable plate 4, the outer surface of the inner catheter 5 is movably sleeved with the inner surface of the outer catheter 1, a second sperm injection hole 6 is provided inside the left side of the inner catheter 5, a slide groove 7 is provided on the top of the left side of the fixed plate 3, a push rod 8 is fixedly installed on the top of the left side of the movable plate 4, the outer surface of the push rod 8 is movably connected to the inner surface of the slide groove 7, a first spring 9 is fixedly connected to the outer surface of the push rod 8, a fixed block 10 is fixedly connected to the other end of the first spring 9, the outer surface of the fixed block 10 is fixedly connected to the outer surface of the fixed plate 3, a U-shaped frame 11 is fixedly installed on the left side of the fixed plate 3, a clamping block 13 is movably sleeved inside the U-shaped frame 11, a second spring 12 is fixedly connected to the top of the clamping block 13, and the top of the second spring 12 is fixedly connected to the top of the inner surface of the U-shaped frame 11.

[0021] By setting the first sperm injection hole 2 and the second sperm injection hole 6, sperm can be transported into the uterine cavity through the second sperm injection hole 6 and the first sperm injection hole 2. When the first sperm injection hole 2 and the second sperm injection hole 6 are staggered, the inner catheter 5 will close the first sperm injection hole 2, so that when the operator inserts the outer catheter 1 into the uterine cavity through the vagina, before sperm is injected, it can effectively prevent secretions from entering the inner catheter 5 through the first sperm injection hole 2, thereby effectively avoiding blockage of the first sperm injection hole 2.

[0022] An outer fixing frame 14 is fixedly installed on the right side of the fixing plate 3 , and a card slot 15 is provided inside the outer fixing frame 14 . There are four card slots 15 , and anti-slip pads 16 are fixedly installed inside the four card slots 15 .

[0023] The anti-skid pad 16 is provided so that the anti-skid pad 16 can play a role in increasing friction.

[0024] Among them, an inner fixed frame 17 located inside the outer fixed frame 14 is fixedly installed on the right side of the fixed plate 3, and an injection tube 18 is movably sleeved inside the inner fixed frame 17. The left end of the injection tube 18 extends to the inside of the inner catheter 5 and is movably sleeved with the inner wall of the inner catheter 5. A syringe barrel 19 is fixedly installed on the right side of the injection tube 18.

[0025] By inserting the injection tube 18 into the inner catheter 5 , sperm can be injected into the inner catheter 5 .

[0026] Among them, an annular block 20 is fixedly installed on the left side of the injection cylinder 19, and a rectangular block 21 is fixedly connected to the left side of the outer surface of the annular block 20. The outer surface of the rectangular block 21 is movably connected to the inner surface of the slot 15 and the anti-slip pad 16 respectively.

[0027] After the operator inserts the injection tube 18 into the inner catheter 5 , the annular block 20 will also be inserted into the outer fixed frame 14 , and then the operator rotates the injection cylinder 19 so that the rectangular block 21 can be inserted into the slot 15 and contact the anti-slip pad 16 .

[0028] Among them, the left side of the annular block 20 is movably connected to a push plate 22, the outer surface of the push plate 22 is movably connected to the inner surface of the outer fixed frame 14 and the outer surface of the inner fixed frame 17 respectively, and the left side of the push plate 22 is fixedly connected to a fixing spring 23, and the left end of the fixing spring 23 is fixedly connected to the right side of the fixing plate 3.

[0029] The fixing spring 23 is in a compressed state, so that the fixing spring 23 can push the push plate 22 to the right under the action of elastic force recovery, thereby making the rectangular block 21 and the anti-slip pad 16 contact more closely.

[0030] A support plate 24 is fixedly sleeved on the right side of the outer surface of the injection cylinder 19 , a rubber plug 25 is movably sleeved inside the injection cylinder 19 , and a piston handle 26 is fixedly connected to the right side of the rubber plug 25 .

[0031] The operator can push the piston handle 26 to the left, thereby causing the rubber plug 25 to move to the left, thereby pushing the sperm inside the syringe 19 into the interior of the inner catheter 5.

[0032] A handle 27 is fixedly installed on the right side of the piston handle 26 , and a fixing groove 28 is provided at the bottom of the piston handle 26 .

[0033] The push handle 27 is provided to facilitate the operator to push the rubber plug 25 to the left or pull it to the right.

[0034] Among them, a mounting box 29 is fixedly installed at the bottom of the right side of the injection cylinder 19, and an inclined block 31 is movably sleeved inside the mounting box 29. The top of the inclined block 31 extends to the inside of the fixed groove 28 and is movably connected to the inner surface of the fixed groove 28. A return spring 30 is fixedly connected to the bottom of the inclined block 31, and the bottom end of the return spring 30 is fixedly connected to the bottom of the inner surface of the mounting box 29. A pull plate 32 is fixedly connected to the right side of the inclined block 31.

[0035] When the inclined block 31 is located inside the fixing groove 28 , the piston handle 26 cannot move to the right, thereby preventing the rubber plug 25 from rebounding.

[0036] Among them, a mounting plate 33 is fixedly installed at the bottom of the mounting box 29, and a threaded rod 34 is sleeved on the internal thread of the right end of the mounting plate 33. The top end of the threaded rod 34 passes through the pull plate 32 and is movably sleeved on the inner wall of the pull plate 32. A round block 35 is fixedly connected to the top end of the threaded rod 34. The outer surface of the round block 35 is movably connected to the outer surface of the pull plate 32, and a rotating block 36 is fixedly sleeved on the bottom of the outer surface of the threaded rod 34.

[0037] The operator can rotate the rotating block 36 to move the threaded rod 34 downward, and then pull the pull plate 32 and the inclined block 31 downward through the round block 35, so that the inclined block 31 remains out of the fixing groove 28.

[0038] Working principle and usage process: First, the operator inserts the outer catheter 1 into the uterine cavity of the female undergoing artificial insemination, and then extracts sperm by using the syringe 19, so that the sperm enters the interior of the syringe 19, and then aligns the syringe 18 with the internal fixed frame 17, thereby inserting the syringe 18 into the interior of the inner catheter 5. At this time, the annular block 20 will be inserted into the interior of the outer fixed frame 14, and the rectangular block 21 will enter the left side of the inside of the card slot 15. Then the operator rotates the syringe 19, so that the annular block 20 drives the rectangular block 21 to rotate, and then the rectangular block 21 is stuck in the inside of the card slot 15. At this time, the fixed spring 23 pushes the push plate 22 to the right under the action of elastic recovery, so that the push plate 22 pushes the annular block 20 to the right, and then the rectangular block 21 and the anti-slip pad 16 fit more closely, thereby preventing the syringe 19 from rotating, making the outer catheter 1 as a whole and the syringe 19 as a whole more firmly connected, and avoiding excessive injection pressure causing the outer catheter 1 as a whole to be separated from the syringe 19 as a whole.

[0039] Then, the operator pushes the push rod 8, so that the push rod 8 drives the movable plate 4 to rotate, and then the movable plate 4 drives the inner guide tube 5 to rotate, so that the second injection hole 6 coincides with the first injection hole 2, thereby releasing the sealing effect on the first injection hole 2. When the operator pushes the push rod 8, the outer surface of the push rod 8 will squeeze and push the outer surface of the block 13, so that the block 13 moves upward, and then the push rod 8 moves to the rightmost side inside the slide groove 7. At this time, the second spring 12 will push the block 13 to reset under the action of elastic force, thereby fixing the push rod 8, and then fixing the inner guide tube 5, so that the second injection hole 6 and the first injection hole 2 remain in a state of coincidence.

[0040] Finally, the operator pushes the button 27 to the left, causing the plug 25 to move to the right, thereby allowing sperm to be injected into the uterine cavity through the outer catheter 1 and the inner catheter 5, thereby completing artificial insemination. When the piston handle 26 moves to the left, the inner surface of the fixed groove 28 will squeeze and push the inclined surface of the inclined block 31, thereby causing the inclined block 31 to move downward, and then allowing the piston handle 26 to move smoothly to the left. When the inclined block 31 is reset under the elastic recovery action of the reset spring 30, so that the inclined block 31 is located inside the fixed groove 28, the piston handle 26 will not be able to move to the right at this time, thereby limiting the piston handle 26 and preventing the internal pressure of the injection barrel 19 from being too high and pushing the piston handle 26 to rebound to the right. The operator can rotate the rotating block 36 to cause the threaded rod 34 to move downward, and then can pull the pull plate 32 and the inclined block 31 downward through the round block 35, so that the inclined block 31 remains out of the fixed groove 28.
