[0048] like Figure 1-8 As shown, the present invention provides an ovulation inducing needle collection device, comprising a body 100, a supporting seat 200 and a needle removal assembly.

[0049] The support base 200 and the body 100 are arranged in a drawer structure, and the support base 200 has a placement slot 210 for placing the collection box 500. An operation port is arranged on the top of the body 100, and a needle removal assembly is arranged at the operation port. The needle removal assembly is used to remove the needle 620 from the syringe 610 and can make the removed needle 620 fall into the collection box 500.

[0050] When in use, first pull out the support seat 200 and put the collection box 500 into the placement groove 210 of the support seat 200, then push the support seat 200 into the body 100, and finally insert the injection with the needle 620 into the needle removal assembly. Under the action of the needle removal assembly, the needle 620 is removed, and there is no need to remove the needle 620 by hand, thereby achieving the purpose of preventing the needle 620 from piercing the hands of medical staff. The removed needle 620 is then placed in the collection box 500 below. After the collection box 500 is full of needles 620, the support seat 200 is pulled out again, the collection box 500 filled with needles 620 is removed, and a new collection box 500 is placed.

[0051] The ovulation-inducing needle collection device provided by the present invention has a simple structure and a reasonable design. By providing a needle removal assembly, there is no need to remove the needle 620 by hand, thereby achieving the purpose of preventing the needle 620 from piercing the hands of medical staff and having high efficiency.

[0052] like Figure 1 , 3 As shown in FIG. 5 , the collection box 500 includes a box body, which is provided with a plurality of accommodating grooves 510 for accommodating needles 620 in a rectangular array.

[0053] like Figure 3 , 4 As shown in Figures 5 and 6, the needle removal assembly includes a first slider 310, a needle removal plate 320 and a switching structure.

[0054] The first slider 310 is disposed in the body 100 and is slidably connected to the body 100 so that the first slider 310 can only slide in a preset direction in the body 100. Two first sliders 310 are provided, and the two first sliders 310 are respectively disposed on both sides of the operation port.

[0055] There are two needle removal plates 320, which are symmetrically arranged. A groove 321 matching the needle seat of the needle 620 is arranged on the opposite side of the two needle removal plates 320. When the needle seat is inserted into the groove 321, the needle 620 can be removed by rotating the syringe 610. The operation is convenient and will not prick the hands of medical staff. The number of grooves 321 is equal to the number of accommodating slots 510 in a row or column on the collection box 500 and corresponds one to one.

[0056] The two ends of the needle removal plate 320 are respectively slidably connected to the two first sliders 310, so that the two needle removal plates 320 can be close to or away from each other. The two needle removal plates 320 have a first distance and a second distance, wherein the first distance is smaller than the second distance.

[0057] The switching structure is in driving connection with the needle removal plate 320. When removing the needle, the switching assembly keeps the distance between the two needle removal plates 320 at the first distance, so that the groove 321 of the needle removal plate 320 can cooperate with the needle seat, thereby achieving the purpose of removing the needle 620. When placing the needle 620, the switching assembly switches the distance between the two needle removal plates 320 from the first distance to the second distance, so that the needle 620 can fall from between the two needle removal plates 320 into the placement box.

[0058] Specifically, when removing the needle, the switching component keeps the distance between the two needle removal plates 320 at the first distance, inserts the needle 620 into the groove 321, rotates the syringe 610, and with the cooperation of the groove 321 and the needle seat, the needle 620 is removed. The operation is simple and efficient, and there is no need for medical staff to manually remove the needle 620, thereby avoiding stabbing the medical staff.

[0059] When the needle 620 is removed, the distance between the two needle removal plates 320 is switched from the first distance to the second distance through the switching assembly, so that the needle 620 can fall from the gap between the two needle removal plates 320 into the receiving groove 510 of the collection box 500 below.

[0060] The needle removal assembly provided in this embodiment has a simple structure, reasonable design, and is easy to operate.

[0061] like Figure 3 , 4 As shown in FIGS. 5 and 6 , the switching structure includes a second slider 330 , a third slider 340 , a connecting rod 350 and a first elastic element 360 .

[0062] Two second sliders 330 are provided, and the two second sliders 330 are respectively connected to the two needle removal plates 320 and can move with the needle removal plates 320. The second slider 330 is slidably connected to the first slider 310 so that the two second sliders 330 can move closer to or farther away from each other.

[0063] The third slider 340 is slidably connected to the body 100 , so that the third slider 340 can move toward or away from the first slider 310 .

[0064] Two connecting rods 350 are provided, and the first ends of the two connecting rods 350 are respectively hinged to the two second sliders 330 , and the second ends of the two connecting rods 350 are both connected to the third slider 340 .

[0065] The first elastic element 360 is used to apply elastic force to the second slider 330 so that the two second sliders 330 tend to move closer to each other. Specifically, both ends of the first elastic element 360 can be connected to the third slider 340 and the body 100 so that the third slider 340 tends to move away from the first slider 310, thereby making the two second sliders 330 tend to move closer to each other.

[0066] Both ends of the first elastic element 360 may also be connected to the two second sliders 330 respectively, so that the two second sliders 330 have a tendency to move toward each other.

[0067] In this embodiment, both ends of the first elastic element 360 may also be connected to the second slider 330 and the body 100 respectively, so that the two second sliders 330 have a tendency to move toward each other.

[0068] The first elastic element 360 can be any component that can apply elastic force, such as a spring, a hydraulic spring, a gas spring, a rubber spring, etc. In the present embodiment, the first elastic element 360 is a spring, and specifically a compression spring.

[0069] When the needle is removed, under the action of the first elastic element 360, the first elastic element 360 keeps the two second sliders 330 close to each other, so that the two needle removal plates 320 are kept at the first distance.

[0070] When placing the needle 620, the third slider 340 is pressed to move the third slider 340 toward the first slider 310, thereby driving the two second sliders 330 away from each other through the connecting rod 350, thereby achieving the purpose of switching the distance between the two needle removal plates 320 from the first distance to the second distance.

[0071] The switching structure provided in this embodiment has a simple structure, reasonable design and convenient operation.

[0072] Preferably, two switching structures are provided, and the two switching structures are respectively provided at the two ends of the needle removal plate 320 to improve the driving stability of the needle removal plate 320.

[0073] Preferably, the needle retrieval plate 320 is detachably connected to the second slider 330 so that the needle retrieval plate 320 matching the target needle 620 can be replaced according to the type of the needle 620, thereby improving the versatility of the entire collecting device.

[0074] It should be noted that the needle removal plate 320 and the second sliding block 330 are detachably connected, which may be a threaded connection or a detachable connection in other ways.

[0075] like Figure 3 , 4 As shown in Figures 5 and 6, the needle removal assembly also includes a fourth slider 370 and a second elastic element 380.

[0076] The number of fourth sliders 370 is relative to and corresponds to the number of second sliders 330. The fourth sliders 370 are slidably connected to the second sliders 330. A connecting portion 371 is provided on the top of the fourth slider 370. The needle removal plate 320 is correspondingly provided with a connecting plug adapted to the connecting portion 371, and a card slot 372 for clamping the needle removal plate 320 is provided on one side of the connecting portion 371.

[0077] The number of the second elastic elements 380 is equal to and corresponds to the number of the fourth sliders 370. The two ends of the second elastic element 380 are respectively connected to the fourth slider 370 and the second slider 330. In the natural state, the second elastic element 380 is used to apply elastic force to the fourth slider 370 so that the slot 372 can clamp the needle removal plate 320.

[0078] When installing the needle plate 320, the fourth slider 370 is moved so that the connection part 371 corresponds to the connection socket 322, and the connection part 371 is inserted into the connection socket 322, so that the needle plate 320 can be installed, and the operation is convenient. Then, under the action of the second elastic element 380, the second elastic element 380 drives the fourth slider 370 to move, so that the slot 372 clamps the needle plate 320, thereby achieving the purpose of improving the stability of the fixing score of the needle plate 320.

[0079] When disassembling the needle removal plate 320, move the fourth slider 370 so that the connecting portion 371 corresponds to the connecting socket 322, and pull the connecting portion 371 out of the connecting socket 322 to achieve the purpose of disassembling the needle removal plate 320, which is easy to operate.

[0080] The second elastic element 380 can be any component that can apply elastic force, such as a spring, a hydraulic spring, a gas spring, a rubber spring, etc. In the present embodiment, the second elastic element 380 is a spring, and specifically a tension spring.

[0081] As Figure 3 , 5 As shown, it also includes a driving component, which is used to drive the first slider 310 to move. The driving component includes a screw rod 410, which is arranged in the body 100, the screw rod 410 is rotatably connected to the body 100, and the screw rod 410 is transmission-connected to the first slider 310 to drive the first slider 310 to move.

[0082] After a row or column of receiving grooves 510 are all filled with needles 620, the screw rod 410 is rotated to move the first slider 310 so that the needle removal plate 320 corresponds to the next row or column of receiving grooves 510, thereby facilitating the movement of the needle removal plate 320 and further improving efficiency.

[0083] like Figure 3 , 5 As shown, the driving assembly also includes a motor 420 , and a power output shaft of the motor 420 is drivingly connected to the screw rod 410 .

[0084] When the needle removal plate 320 needs to be moved, the motor 420 is started, and the motor 420 drives the screw rod 410 to rotate, thereby driving the first slider 310 to move a preset distance, so that the needle removal plate 320 corresponds to the next row or column of accommodating grooves 510.

[0085] Specifically, a driving wheel 430 is coaxially sleeved on the power output shaft of the motor 420, a driven wheel 440 is coaxially sleeved on the screw rod 410, and a transmission element 450 is annular and sleeved on the driving wheel 430 and the driven wheel 440, and the transmission element 450 can rotate with the rotation of the driving wheel 430 and the driven wheel 440. The transmission element 450 can be a synchronous belt, a transmission belt, a transmission chain, etc.

[0086] like Figure 1 As shown, a control component is disposed on the body 100 , and the control component includes a first button 110 and a second button 120 .

[0087] The first button 110 is electrically connected to the motor 420 . When in operation, the first button 110 is pressed once, thereby controlling the motor 420 to drive the second slider 330 to move a preset distance in a first preset direction.

[0088] The second button 120 is electrically connected to the motor 420. When the second button 120 is in operation, the motor 420 is controlled to drive the second slider 330 to move in a second preset direction and a preset distance. The first preset direction is opposite to the second preset direction.

[0089] It should be noted that the first button 110 and the second button 120 can be physical buttons or virtual buttons. In this embodiment, the first button 110 and the second button 120 are both physical buttons.

[0090] In this embodiment, by providing the first button 110 and the second button 120 , it is possible to facilitate the operation of the motor 420 to drive the first slider 310 to move, thereby further improving the efficiency.
