Detailed implementation manners

[0038] To make the objectives, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0041] In the prior art, permanent magnets are generally used as adsorption components in needle finders. After the needle finding is completed, medical staff need to hold the needle tool adsorbed on the permanent magnet to apply force to remove it. During this process, it is easy to cause stabbing injuries and secondary dropping, which is not only inconvenient to use but also poses a risk of disease infection for medical staff.

[0042] Based on the above problems in the prior art, as Figure 2 shown, the present invention provides an intelligent needle finder, which includes: a housing 100, a shaft rod 110 is arranged at the central axis of the housing 100, a driving component 400 is arranged inside the housing 100, and a recycling box 120 which is detachably arranged on the outside of the housing 100 and is open towards one side of the housing 100; a drum 200, the drum 200 is rotatably arranged on the shaft rod 110, a magnetic attraction part 201 corresponding to an electromagnet arranged inside the drum 200 is arranged on the outside of the drum 200, the drum 200 is connected to the driving component 400, and the driving component 400 is used to drive the drum 200 to rotate; a grip rod 300, the grip rod 300 is arranged on the housing 100, a handle 310 which is linked with the driving component 400 is arranged on the grip rod 300, and a switch 320 which is electrically connected to the electromagnet.

[0043] In the present invention, by arranging the driving component 400 inside the housing 100 and the recycling box 120 outside, the driving component 400 can drive the drum 200 to rotate so that the magnetic attraction part 201 corresponds to the recycling box 120. When a needle tool is sucked during use, after rotating the drum 200 through the handle 310 and closing the electromagnet through the switch 320, the needle tool falls into the recycling box 120 under the action of gravity. This not only facilitates subsequent processing but also effectively avoids medical staff from contacting the dropped needle tool and is convenient for needle finding operation.

[0044] Specifically, as Figure 1 and Figure 2 shown, in this embodiment, the intelligent needle finder is specifically composed of a housing 100, a drum 200 and a grip rod 300. Among them, the housing 100 is used to install the driving component 400 to realize the driving rotation of the drum 200. At the same time, in order to realize the connection between the housing 100 and the drum 200, a shaft rod 110 is also arranged at the central axis position of the housing 100. The above-mentioned drum 200 is freely rotatably arranged on the shaft rod 110. After the drum 200 and the housing 100 are installed in a predetermined position, the drum 200 is connected to the driving component 400. At this time, the rotation angle of the drum 200 is controlled and restricted by the driving component 400. Therefore, by controlling the component, the effect of switching the magnetic attraction part 201 on the drum 200 to correspond to the ground or the recycling box 120 can be realized, and further the effects of sucking the needle tool on the ground and storing the needle tool in the recycling box 120 can be realized.

[0045] In this embodiment, the shape of the drum 200 is cylindrical, and its interior is hollow. The diameter dimension of the drum 200 should be less than or equal to the curved part on the housing 100. The reason is that the recycling box 120 is installed on one side of the housing 100. Through the size setting and the structural cooperation with the recycling box 120, the situation of the needles falling again can be avoided.

[0046] In this embodiment, the grip rod 300 is arranged on the housing 100, specifically on the upper side of the housing 100. The grip rod 300 is used to be held by the operator to control the corresponding range between the drum 200 and the ground. At the same time, a handle 310 linked with the drive assembly 400 and a switch 320 electrically connected to the electromagnet are arranged on the grip rod 300. During actual use, after the operator completes the needle searching work, the control assembly can be manipulated by driving the handle 310 to move, so as to realize the rotation of the drum 200. When the handle 310 is in a predetermined state, the drum 200 rotates to an extreme position. At this time, the magnetic attraction part 201 on the drum 200 corresponds to the recycling box 120 arranged outside the housing 100. One side of the recycling box 120 corresponding to the housing 100 is open. Therefore, when the operator presses the switch 320 to turn off the electromagnet, the needles on the drum 200 lose the restraint of the magnetic attraction force and fall into the recycling box 120 under the action of gravity, thus realizing the process of needle searching and storage of the needles.

[0047] After the above process is completed, the operator can also reset the position of the drum 200 by controlling the handle 310, which is convenient for direct use during the next needle searching. Through the linkage setting of the handle 310 on the grip rod 300 and the drive assembly 400 in the present invention, the rotation of the drum 200 can be controlled only by controlling the grip rod 300, forming the correspondence between the magnetic attraction part 201 and the ground or the correspondence with the recycling box 120. At the same time, the electromagnet is controlled by the switch 320 on the grip rod 300, and the needles are sucked and recycled corresponding to the above different states. The operation process is very simple while effectively avoiding the contact between the operator and the needles, effectively preventing the needles from falling again or injuring the operator, ensuring the safety of the operator while improving the needle searching efficiency.

[0048] In another feasible embodiment of the present invention, as Figure 1 and Figure 2 shown, for the convenience of medical staff's operation, in this embodiment, the above intelligent needle finder is set to be operated by a single grip rod 300, so as to achieve the effect of single - hand operation. To maintain the operation balance of the intelligent needle finder, the grip rod 300 should be arranged in the middle of the whole intelligent needle finder, that is, the housing 100 is arranged at the central position. Therefore, in this embodiment, the above shaft rod 110 is extended to both sides of the housing 100, that is, as Figure 2As shown in the structural style, freely rotating rollers 111 are respectively provided at both ends of the shaft 110, and the diameter of the roller 111 is larger than the diameter of the above-mentioned drum 200, thereby assisting the operator to move the intelligent needle finder without affecting the magnetic attraction effect of the drum 200 on the ground.

[0049] Correspondingly, if Figure 2 As shown, the above-mentioned drum 200 includes a first drum body 210 and a second drum body 220, and the first drum 200 and the second drum 200 are rigidly connected by a connecting rod 221. The length of the connecting rod 221 is adapted to the thickness of the shell 100, so that the first drum body 210 and the second drum body 220 can be limited on both sides of the shell 100. The first drum body 210 and the second drum body 220 are respectively rotatably arranged on the shaft rods 110 on both sides of the shell 100 to achieve the effect of synchronous rotation; a slide groove 130 is also hollowed out on the shell 100, and the slide groove 130 is arranged along a predetermined arc. The connecting rod 221 is slidably sleeved in the slide groove 130. When the magnetic attraction portion 201 on the first roller 200 and the second roller 200 corresponds to the ground, the connecting rod 221 is located at one end in the slide groove 130 to form a limit. When the magnetic attraction portion 201 on the first roller 200 and the second roller 200 corresponds to the recovery box 120, the connecting rod 221 is located at the other end in the slide groove 130 to form a limit. Therefore, the driving component 400 can accurately operate the extreme rotation position of the first roller 200 and the second roller 200 to achieve the effect of accurately corresponding to the ground and accurately corresponding to the recovery box 120.

[0050] Furthermore, if Figure 2 and Figure 3 As shown, a first recovery bin 121 and a second recovery bin 122 are provided in the recovery box 120, wherein the first recovery bin 121 corresponds to the first cylinder 210, and the second recovery bin 122 corresponds to the second cylinder 220, thereby forming a correspondence and acceptance of the magnetic attraction portion 201 on the first cylinder 210 and the second cylinder 220;

[0051] In actual setting, since the recovery box 120 is installed corresponding to the housing 100, the distance between the first cylinder 210 and the second cylinder 220 is small, in order to prevent the side of the recovery box 120 from knocking off the needle attracted by the magnetic attraction part 201 when the first cylinder 210 and the second cylinder 220 rotate, Figure 3 As shown, in this embodiment, a baffle 123 is provided on one side of the first recycling bin 121 and the second recycling bin 122 corresponding to the magnetic attraction portion 201, respectively. The baffle 123 is rotatably connected to the recycling box 120 and is elastically reset. This structure can be specifically realized by providing a compression spring at the rotating shaft. Correspondingly, as shown in FIG. Figure 4As shown, tenons 202 are respectively provided at positions corresponding to the magnetic attraction portion 201 on the first cylinder 210 and the second cylinder 220 (the tenons 202 of the first cylinder 210 and the second cylinder 220 have the same structure, and the second cylinder 220 can be set with reference to the first cylinder 210), and the tenons 202 are continuously and protrudingly arranged along the outer side of the arc surface where the magnetic attraction portion 201 is located, and both ends of the tenons 202 form a transition with the outer side of the cylinder along the inclined arc surface.

[0052] In actual use, please combine Figure 2 , Figure 3 and Figure 4 Taking the first cylinder 210 and the first recovery bin 121 as an example, when the intelligent needle finder is in the needle finding state, the magnetic attraction portion 201 on the first cylinder 210 faces downward, and the magnetic attraction portion 201 and the first recovery bin 121 are staggered. When the needle finding is completed, the operator controls the driving assembly 400 to drive the first cylinder 210 to rotate, and the magnetic attraction portion 201 follows the first cylinder 210 to rotate toward the first recovery bin 121. In this process, the tenons 202 at both ends of the magnetic attraction portion 201 come into contact with the baffle 123, causing the baffle 123 to generate It rotates to form a certain distance between itself and the magnetic attraction part 201, so as to avoid the needle adsorbed on the magnetic attraction part 201. When the magnetic attraction part 201 completely corresponds to the first recovery bin 121, since the length of the tenon 202 corresponds to the range of the magnetic attraction part 201, the tenon 202 no longer contacts the blocking piece 123. Therefore, the blocking piece 123 is reset to make the first recovery bin 121 completely cover the magnetic attraction part 201. When the operator turns off the electromagnet, the needle falls into the first recovery bin 121 under the action of gravity, so that the needle is stored.

[0053] In this embodiment, it is preferred that the bottom of the first recovery bin 121 and the second recovery bin 122 be set to a pocket shape with a certain curvature, so as to achieve the function of guiding and storing the needles falling into the first recovery bin 121 and the second recovery bin 122. When the first cylinder 210 and the second cylinder 220 rotate in the opposite direction, the needles in the recovery box 120 can be prevented from falling to the ground again along the gap left by the baffle 123 being moved.

[0054] In another embodiment of the present invention, Figure 1 and Figure 2As shown, one end of the above-mentioned first cylinder 210 and second cylinder 220 corresponding to the housing 100 is in sliding contact with the housing 100 respectively. One end of the first cylinder 210 and second cylinder 220 corresponding to the roller 111 is arranged at a predetermined distance. The purpose of this setting is, on the one hand, to make the first cylinder 210 and second cylinder 220 close to the housing 100 to maintain stable connection with the driving assembly 400, and on the other hand, to avoid driving the first cylinder 210 and second cylinder 220 to rotate due to the friction force when the roller 111 rotates, so as to prevent affecting the position correspondence of the magnetic attraction part 201 in different states of the intelligent needle finder.

[0055] Meanwhile, as Figure 2 shown, on the basis of the installation of the above-mentioned first cylinder 210 and second cylinder 220, an installation groove 140 is provided on one side of the housing 100 facing the first cylinder 210. The installation groove 140 is recessed inward. The above-mentioned driving assembly 400 is arranged inside the installation groove 140. The inside of the above-mentioned grip rod 300 is hollow, and the part fixedly connected to the housing 100 is in communication with the installation groove 140. The installation groove 140 is open at the end corresponding to the first cylinder 210. A driving shaft 230 is provided at the end of the first cylinder 210 corresponding to the installation groove 140. The driving shaft 230 is connected to the driving assembly 400, so that the driving shaft 230 can be driven to rotate by the driving assembly 400 to achieve the effect of controlling the rotation of the first cylinder 210 and second cylinder 220.

[0056] More specifically, as Figure 2 shown, the above-mentioned driving assembly 400 is specifically composed of an amplification runner 410, a tension spring 420, a first rope 430, and a second rope 440. Among them, the amplification runner 410 is positioned and rotatably arranged in the installation groove 140, and corresponds to the position where the grip rod 300 penetrates through the housing 100. One end of the tension spring 420 is fixedly arranged in the installation groove 140, specifically at the position on one side of the installation groove 140 corresponding to the ground. The other end of the tension spring 420 is fixedly connected to the driving shaft 230. At the same time, one end of the first rope 430 is fixedly connected to the driving shaft 230, and the other end of the first rope 430 is wound around the amplification runner 410. The above-mentioned second rope 440 is arranged inside the hollow of the grip rod 300. One end of it is wound around the amplification runner 410, and the other end is connected to the handle 310 on the grip rod 300. The specific arrangement of the above structure can be referred to Figure 5 and Figure 6 .

[0057] In this embodiment, when an operator operates the handle 310, the second rope body 440 is pulled, driving the amplification rotating wheel 410 to rotate. At this time, the amplification rotating wheel 410 winds the first rope body 430, forming a pull on the drive shaft 230. This pull forms a component force on the drive shaft 230 in the radial direction of the housing 100, causing the drive shaft 230 to be pulled and move. Since the first cylinder 210 and the second cylinder 220 are both rotatably arranged on the shaft rod 110, an effect of rotating the first cylinder 210 and the second cylinder 220 is formed, so that the magnetic attraction part 201 can be rotated from the corresponding ground position to the position corresponding to the recycling box 120. At the same time, during this process, the tension spring 420 is stretched to store elastic potential energy. When the force applied by the operator to the handle 310 disappears, the tension spring 420 is reset under the drive of the elastic potential energy of the tension spring 420, driving the first cylinder 210 and the second cylinder 220 to rotate and reset to the initial state, thus eliminating the need for the operator to repeatedly operate and facilitating the next needle searching operation.

[0058] Specifically, as Figure 2 shown, the above-mentioned amplification rotating wheel 410 includes a first wheel disc 411 and a second wheel disc 412 which are stacked and fixedly connected. Among them, the diameter of the first wheel disc 411 is larger than the diameter of the second wheel disc 412. The above-mentioned first rope body 430 is wound around the first wheel disc 411, and the second rope body 440 is wound around the second wheel disc 412. Moreover, the winding directions of the first rope body 430 and the second rope body 440 on the first wheel disc 411 and the second wheel disc 412 are opposite. Please refer to Figure 5 and Figure 6 . When the second rope body 440 is pulled upward by the handle 310, the other end of the second rope body 440 wound around the second wheel disc 412 drives the second wheel disc 412 to rotate, and the first wheel disc 411 rotates synchronously. Since the diameter of the second wheel disc 412 is smaller than the diameter of the first wheel disc 411, the winding length of the first rope body 430 by the first wheel disc 411 is much larger than the height by which the second rope body 440 is lifted. Therefore, the effect of amplification operation is achieved, which not only reduces the difficulty for the operator to control the handle 310, but also ensures that the first cylinder 210 and the second cylinder 220 can rotate to the predetermined position.

[0059] On the basis of the above embodiment, as Figure 5 and Figure 6As shown in the figure, to further facilitate the operator to adjust the dial handle 310, in this embodiment, a positioning wheel 330 is further provided inside the grip rod 300. The positioning wheel 330 functions as a fixed pulley and is used to change the pulling direction of the second rope body 440. In this embodiment, a part of the second rope body 440 is wound around the positioning wheel 330. The middle part of the dial handle 310 is rotatably connected to the grip rod 300. One end of the dial handle 310 extends out of the outer side of the grip rod 300, and the end of the dial handle 310 located inside the grip rod 300 is fixedly connected to the second rope body 440. Through the setting of the positioning pulley, the operator can hold the dial handle 310 and the handle on the grip rod 300, that is, the operator can drive the end of the second rope body 440 to be pulled downward. At the same time, on the other side of the positioning wheel 330, the effect of pulling the second rope body 440 upward is achieved, forming the above-mentioned effect of driving the first cylinder 210 and the second cylinder 220 to rotate. The advantage of such a setting in this embodiment is that it is convenient for the operator to operate with one hand, and at the same time, it will not affect the operator to use the same hand to control the switch 320 at the same time, thereby making the above-mentioned control process more convenient.

[0060] In the above embodiment, the connecting rod 221 between the first cylinder 210 and the second cylinder 220 and the hollowed-out chute 130 on the housing 100 have the effect of restricting the rotation limit of the first cylinder 210 and the second cylinder 220. As Figure 5 and Figure 6 shown, when the tension spring 420 is in a slightly stretched state, at this time, the magnetic attraction parts 201 on the first cylinder 210 and the second cylinder 220 face the ground correspondingly, and one end of the connecting rod 221 located in the chute 130. When the driving assembly 400 pulls the first cylinder 210 and the second cylinder 220 to rotate to the position where the magnetic attraction parts 201 correspond to the recycling box 120, at this time, the other end of the connecting rod 221 located in the chute 130. Through the cooperation and limitation of the connecting rod 221 and the chute 130, the corresponding accuracy between the magnetic attraction parts 201 and the recycling box 120 or the ground can be effectively guaranteed.

[0061] Based on the above embodiment, in another feasible implementation manner of the present invention, a magnetic sensor connected to the electromagnet circuit and corresponding in position is further provided inside the above-mentioned drum 200. The magnetic sensor can specifically be a Hall element. The magnetic sensor is also connected to the prompting element provided on the above-mentioned grip rod 300. When the electromagnet adsorbs the needle, the needle is magnetized, resulting in a change in the magnetic field distribution of the electromagnet. This change in the magnetic field distribution can be accurately recognized by the magnetic sensor and an electrical signal is generated and sent to the prompting element. By prompting the operator through the prompting element, the operator can quickly understand the needle searching situation.

[0062] In this embodiment, the prompting element can specifically be a combination of one or more of a lamp group, a speaker or a vibration motor. By prompting the operator through light effects, sounds and vibrations, the accurate perception of the operator can be effectively guaranteed.

[0063] In the above embodiments, the first cylinder 210 and the second cylinder 220 are preferably made of plastic materials to ensure that the magnetic attraction range of the electromagnet only corresponds to the magnetic attraction part 201. Around the magnetic attraction part 201, a magnetic isolation sheet can also be provided to further ensure that the needle tool will only be attracted within the range of the magnetic attraction part 201, so as to ensure that the needle tool can accurately enter the recycling box 120 during subsequent processing. At the same time, the first cylinder 210 and the second cylinder 220 made of plastic also have the effects of being easy to disinfect and clean, thus meeting the requirements of hospital infection control.

[0064] In another feasible embodiment of the present invention, as Figure 3 shown, a plurality of tenons 124 are further provided at the part of the recycling box 120 corresponding to the housing 100. Correspondingly, a plurality of grooves are provided on the housing 100 at the positions corresponding to the plurality of tenons 124. The plurality of tenons 124 and the plurality of grooves are in one-to-one correspondence and are snap-connected to realize the effect of firmly fixing the recycling box 120 on the housing 100 and being convenient for disassembly. In this application, the actual structure of the tenons 124 is not limited, and those skilled in the art can set it according to the actual situation.

[0065] In addition, the above recycling box 120 is preferably set as a transparent recycling box 120 or a partially transparent recycling box 120, so that the operator can clearly observe the needle tool storage status in the recycling box 120 during use, which is convenient for counting or determining whether the needle tool is stored in the recycling box 120.

[0066] Based on the above embodiments, the actual use process of the intelligent needle finder of the present invention is as follows:

[0067] As Figure 1 and Figure 5 shown, when the operator is searching for a needle, the switch 320 is turned on, and the electromagnet starts to work. The operator moves the intelligent needle finder in a predetermined space with the assistance of the roller 111. When a needle tool is adsorbed on the drum 200, the magnetic field distribution of the electromagnet changes, and under the action of the magnetic sensor, the operator is reminded through the prompting element provided on the grip 300.

[0068] When the needle searching operation is completed, as Figure 5 and Figure 6 shown, the operator applies force to hold the dial handle 310 and the handle. At this time, the second rope body 440 is pulled upward by a certain distance, the magnification rotating wheel 410 rotates to wind the first rope body 430, the traction drive shaft 230 moves, and the drum 200 rotates synchronously, so that the magnetic attraction part 201 is adjusted from the corresponding ground position to the position corresponding to the recycling box 120. At this time, the operator presses the switch 320 to turn off the electromagnet, and the needle tool falls into the predetermined area of the recycling box 120 under the action of gravity and the guiding action of the inner wall of the recycling box 120, completing the search and storage of the needle tool.

[0069] The operator cancels the force applied to the dial handle 310, and the above structure resets under the action of the tension spring 420, which is convenient for the next use.

[0070] In summary, the present invention provides an intelligent needle finder, which specifically includes: a housing, a shaft rod is arranged at the central axis of the housing, a driving component is arranged inside the housing, and a recovery box that is detachably arranged on the outside of the housing and is open towards one side of the housing; a drum, the drum is rotatably arranged on the shaft rod, a magnetic attraction part corresponding to the electromagnet arranged in the drum is arranged on the outside of the drum, the drum is connected to the driving component, and the driving component is used to drive the drum to rotate; a grip rod, the grip rod is arranged on the housing, a dial handle that is linked with the driving component is arranged on the grip rod, and a switch that is electrically connected to the electromagnet. By arranging a driving component inside the housing and a recovery box outside the housing in the present invention, the driving component can drive the drum to rotate so that the magnetic attraction part corresponds to the recovery box. When a needle is sucked during use, after the drum is rotated by the dial handle and the electromagnet is turned off through the switch, the needle falls into the recovery box under the action of gravity, which is convenient for subsequent processing and effectively avoids the contact between medical staff and the dropped needle, facilitating the needle finding operation.

[0071] It should be understood that the application of the present invention is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all these improvements and transformations should fall within the protection scope of the appended claims of the present invention.
