A biomedical piezoelectric material polarization device

Abstract

This invention provides a biomedical piezoelectric material polarization device, belonging to the technical field of piezoelectric material polarization devices. It includes an outer casing assembly, an inner oil tank assembly, a linkage lifting component, a second adjustment component, an upper anode column assembly, and a linkage limiting component. The casing cover is hinged to the upper rear side of the bottom casing. The linkage lifting component synchronizes the lifting and lowering of the cathode plate with the opening and closing of the casing cover. When the casing cover is open, the cathode plate can be raised to a position outside the insulated inner oil tank. When the casing cover is closed, the cathode plate is immersed in the silicone oil inside the insulated inner oil tank, quickly facilitating sample placement before polarization. The second adjustment component allows for flexible adjustment of the cathode plate's limit position relative to the casing cover. The linkage limiting component ensures that the casing cover is normally closed when not in use, and that opening the casing cover causes the rack's inner connecting plate to move inward synchronously, safely limiting the upper limit position of the cathode plate.

Description

Technical Field

[0001] This invention relates to the field of piezoelectric material polarization device technology, and particularly to a biomedical piezoelectric material polarization device. Background Technology

[0002] In electronics, the main application of medical piezoelectric materials is in the fabrication of various sensitive sensors, specifically composed of piezoelectric ceramic micropowders, fibers, and polymers. Sensors made from these materials can increase the sensitivity of medical ultrasound array detectors by several orders of magnitude, enabling the detection of much weaker signals and the acquisition of clearer images.

[0003] Currently, piezoelectric composite materials have broad application prospects in blood measurement, such as blood pressure monitors and blood flow meters; in physiological monitoring, such as fetal heart rate monitors and ventilators; and in fluid monitoring, such as flow time meters, level gauges, and infusion counters.

[0004] As a current technology for processing biomedical piezoelectric materials, the polarization method still adopts the traditional industrial method, which uses relatively bulky equipment. It involves directly heating the silicone oil in the silicone oil tank with a heating rod in a fixed position, and manually connecting the positive and negative electrodes on both sides of the placed piezoelectric material sample. This technology is relatively backward. Summary of the Invention

[0005] The purpose of this invention is to provide a biomedical piezoelectric material polarization device. By utilizing the linkage between the lifting component and the cover, the sample to be polarized can be placed quickly. Furthermore, the upper and lower movement limits of the cathode plate relative to the opening and closing action of the cover can be flexibly adjusted through the second adjustment component.

[0006] The objective of this invention is achieved through the following technical solution: a biomedical piezoelectric material polarization device, comprising an outer casing assembly, an inner oil tank assembly, a linkage lifting component, a second adjustment component, and an upper anode column assembly. The outer casing assembly includes a bottom casing, the inner oil tank assembly includes an insulated inner oil tank shell, the linkage lifting component includes a cathode plate and a rotating connecting rod, the second adjustment component includes an adjustment screw, and the upper anode column assembly includes an internal plate, an anode pressure column, and a silver electrode.

[0007] A cover is hinged to the rear side of the upper end of the bottom tank, and an insulated inner oil tank shell is installed at the bottom of the bottom tank.

[0008] The inner bottom surface of the box cover is symmetrically slidably connected to an upper rotating seat, and the upper end of the inner cavity of the bottom box is symmetrically slidably connected to a cathode sliding column. The cathode plate is fixedly connected to the bottom end of the array of cathode sliding columns, and the top ends of the cathode sliding columns on the same side are fixedly connected to an upper connecting horizontal plate. One end of the rotating connecting rod is rotatably connected to the upper rotating seat, and the other end is rotatably connected to the upper connecting horizontal plate.

[0009] The two sets of upper rotating seats are connected by a lead screw slide, the adjusting lead screw is screwed into the inner middle of the box cover, and the lead screw slide is connected in conjunction with the adjusting lead screw;

[0010] The main body of the box lid has a sliding column that can be raised and lowered, and the inner plate is fixedly connected to the bottom of the array of lifting columns; anode pressure columns can be installed at different positions at the bottom of the inner plate, and silver electrode sheets are connected to the bottom of the anode pressure columns.

[0011] The process of using the technical solution of the present invention is as follows:

[0012] The inner cavity of the insulated inner oil tank shell can be pre-filled with polarization silicone oil, and the circulation of the thermal silicone oil inside the insulated inner oil tank shell is achieved through heating and pump mechanism.

[0013] After the box lid is opened, the biomedical piezoelectric material to be polarized can be placed on the top surface of the cathode plate;

[0014] During the opening of the box cover, the rotating connecting rod will form a screw connection between the upper rotating seat and the upper connecting horizontal plate, which will drive the symmetrically distributed array of cathode sliding columns to move upward, so that the cathode plate moves upward to the position exposed outside the silicone oil in the heat-insulated inner oil tank shell, and is convenient for placing the sample to be polarized.

[0015] Furthermore, at this time, the opening angle of the lid is sufficient to provide enough space for placing the sample to be polarized;

[0016] Subsequently, the sample to be polarized can be placed on the top surface of the cathode plate in a certain arrangement. In order to prevent the sample to be polarized from moving randomly after placement, silicone grease can be applied to the top surface of the cathode plate so that the sample to be polarized is vacuum adsorbed on the top surface of the cathode plate.

[0017] As the lid is closed, the sample to be polarized, placed on the top surface of the cathode plate, is immersed in the silicone oil inside the insulated inner oil tank.

[0018] The lifting slide column, which can be raised and lowered, drives the built-in plate and the anode pressure column and silver sheet electrode installed in different positions in the built-in plate to move downward until the silver sheet electrode is pressed against the sample surface to be polarized.

[0019] By connecting each set of anode pressure columns to the cathode plate, and with the flow of hot silicone oil and the through hole in the middle of the cathode plate, the pre-applied silicone oil paste melts and integrates into the heat-insulated inner oil tank shell, so that the two ends of the sample to be polarized can be connected to the silver sheet electrode and the cathode plate respectively, thereby achieving rapid polarization operation.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects:

[0021] (1) The present invention creatively combines the lifting and lowering movement of the cathode plate with the opening and closing of the cover to form a joint action, so that after the cover is opened, the cathode plate can be lifted to be exposed outside the heat-insulated inner oil tank shell, which is convenient for placing the sample to be polarized. After the cover is closed, the cathode plate can be immersed in the silicone oil in the heat-insulated inner oil tank shell. Thus, the sample placement and silicone oil immersion of the cathode plate can be realized by using the opening and closing action of the cover.

[0022] (2) Moreover, the silicone oil in the heat-insulating inner oil tank shell of the present invention is not a heating source fixed in a certain position, but adopts a circulating heating method, which can make the hot silicone oil in the heat-insulating inner oil tank shell uniformly wrap the cathode plate, thereby improving the polarization efficiency.

[0023] (3) Furthermore, the present invention also provides a second adjustment component in the cover. Through the coordinated transmission formed by the adjustment screw and the screw slide, it can not only achieve the stable stay of the upper rotating seat in the current sliding position without turning the adjustment screw, but also allow the rotating connecting rod to stably drive the cathode slide column and the cathode plate to move up and down synchronously with the opening and closing action of the cover through the rotating connection formed between the upper rotating seat and the upper connecting horizontal plate; and after turning the adjustment screw, the lateral stopping position of the upper rotating seat can also be adjusted, so that the limit position of the up and down movement of the cathode plate is adjusted within a certain range relative to the opening and closing position of the cover, thereby making the linkage between the up and down movement of the cathode plate and the opening and closing action of the cover more flexible.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-8 As shown, a biomedical piezoelectric material polarization device has a cover 103 hinged to the rear side of the upper end of the bottom box 101 in the outer box assembly 1. The heat-insulated inner oil tank shell 201 is installed at the bottom of the bottom box 101, and the silicone oil in the heat-insulated inner oil tank shell 201 can be heated and circulated.

[0037] The inner bottom surface of the cover 103 is symmetrically slidably connected to an upper rotating seat 308. The upper end of the inner cavity of the bottom box 101 is symmetrically slidably connected to cathode sliding columns 302. The cathode plate 303 is fixedly connected to the bottom end of the array of cathode sliding columns 302. The top ends of the cathode sliding columns 302 on the same side are fixedly connected to an upper connecting horizontal plate 305. One end of the rotating connecting rod 309 is rotatably connected to the upper rotating seat 308, and the other end is rotatably connected to the upper connecting horizontal plate 305.

[0038] The opening and closing action of the cover 103 can drive the cathode plate 303 to lift and lower synchronously through the transmission mechanism. This allows the cathode plate 303 to be lifted to the position outside the silicone oil in the heat-insulated inner oil tank shell 201 after the cover 103 is opened. After the bottom box 101 is closed, the cathode plate 303 can be inserted into the silicone oil in the heat-insulated inner oil tank shell 201.

[0039] A lead screw slide 401 is connected between the two sets of upper rotating seats 308. The adjusting lead screw 402 is screwed into the inner middle of the box cover 103, and the lead screw slide 401 is connected in the adjusting lead screw 402.

[0040] This allows the cathode slide 302 to be adjusted within a small range by turning the adjusting screw 402 and the screw slide 401 after the cover 103 is opened. This enables the limit position of the cathode plate 303 to be adjusted within a certain range relative to the limit position of the opening and closing action of the cover 103, making the linkage relationship between the cathode plate 303 and the cover 103 more precise.

[0041] The main body of the box cover 103 has a liftable sliding column 502 that can be slidably inserted. The inner plate 505 is fixedly connected to the bottom of the array of lifting sliding columns 502. Anode pressure columns 507 can be installed at different positions at the bottom of the inner plate 505. Silver sheet electrodes 508 are connected to the bottom of the anode pressure columns 507. Samples to be polarized can be placed at different positions on the top surface of the cathode plate 303 that are directly opposite each set of silver sheet electrodes 508.

[0042] The inner cavity of the insulated inner oil tank shell 201 can be pre-filled with polarization silicone oil, and the circulation of thermal silicone oil inside the insulated inner oil tank shell 201 can be achieved through heating and pump mechanism.

[0043] After the box cover 103 is opened, the biomedical piezoelectric material to be polarized can be placed on the top surface of the cathode plate 303;

[0044] During the opening of the box cover 103, the rotating connecting rod 309 will form a screw connection between the upper rotating seat 308 and the upper connecting horizontal plate 305, thereby driving the symmetrically distributed array of cathode sliding columns 302 to move upward, so that the cathode plate 303 moves upward to a position exposed outside the silicone oil in the heat-insulated inner oil tank shell 201, and is convenient for placing the sample to be polarized.

[0045] At this time, the opening angle of the box cover 103 is also sufficient to provide enough space for the placement of the sample to be polarized;

[0046] Subsequently, the sample to be polarized can be placed on the top surface of the cathode plate 303 in a certain arrangement. In order to prevent the sample to be polarized from moving randomly after placement, silicone grease can be applied to the top surface of the cathode plate 303 so that the sample to be polarized is vacuum adsorbed on the top surface of the cathode plate 303.

[0047] As the cover 103 is closed, the sample to be polarized placed on the top surface of the cathode plate 303 can be immersed in the silicone oil inside the heat-insulated inner oil tank shell 201.

[0048] The lifting slide column 502, which can be raised and lowered, drives the built-in plate 505 and the anode pressure column 507 and silver sheet electrode 508 installed at different positions in the built-in plate 505 to move downward until the silver sheet electrode 508 is pressed against the sample surface to be polarized.

[0049] When the anode pressure columns 507 and cathode plates 303 are connected, the pre-applied silicone oil melts and is incorporated into the heat-insulated inner oil tank shell 201 as the hot silicone oil flows and the through hole in the middle of the cathode plate 303 is opened. This allows the two ends of the sample to be polarized to be connected to the silver sheet electrode 508 and the cathode plate 303 respectively, thereby enabling rapid polarization operation.

[0050] The specific structures of the outer casing assembly 1 and the inner fuel tank assembly 2 are as follows: Figure 2 and Figure 3 As shown, the rear axle seat 102 is fixedly connected to the upper end of the rear side of the bottom box 101, and the rear side of the box cover 103 is symmetrically fixedly connected with corner structure rotating arms 105. The rear axle 104 is rotatably connected in the rear axle seat 102, and the two sets of rotating arms 105 are respectively inserted and fixed at both ends of the rear axle 104.

[0051] The heating oil pump 202 is fixedly installed on the outer side of the bottom box 101. The inlet and outlet ends of the heating oil pump 202 are respectively connected to the oil extraction pipe 203 and the oil return pipe 204. The oil extraction pipe 203 and the oil return pipe 204 pass through the side wall of the bottom box 101 and are connected to the heat-insulated inner oil tank shell 201.

[0052] Furthermore, the main body of the insulated inner oil tank shell 201 is made of a material with heat insulation function, and the heating oil pump 202 is an oil pump with heating function, which allows the silicone oil to circulate in the insulated inner oil tank shell 201, making the temperature of the silicone oil in the insulated inner oil tank shell 201 more uniform and improving the polarization effect.

[0053] The specific structure of the linkage lifting component 3 is as follows: Figure 4 As shown, an inner slide block 301 is symmetrically fixed at the upper end of the inner cavity of the bottom box 101, and the cathode slide block 302 is slidably connected in the inner slide block 301.

[0054] Any set of cathode sliding pins 302 can be selected as the wired cathode to form cathode conductivity;

[0055] The cathode plate 303 has a series of bottom positioning holes 304 in its main body. Each bottom positioning hole 304 can be used to place a biomedical piezoelectric material sample to be polarized, so that the sample is immersed in the silicone oil in the heat-insulating inner oil tank shell 201 along with the cathode plate 303, and the sample is polarized in a relatively open manner relative to the silicone oil, which has the advantage of being relatively efficient.

[0056] Furthermore, a copper conductive isolation mechanism can be installed in each set of bottom positioning holes 304. The biomedical piezoelectric material sample can be placed inside the copper conductive isolation mechanism to perform polarization of the sample in isolation from silicone oil. Although the efficiency will be relatively reduced, it will not allow silicone oil to penetrate into the biomedical piezoelectric material sample. A cleaning operation is required after polarization.

[0057] The bottom surface of the inner cavity of the box cover 103 is symmetrically fixed with an inner slide rail 306. Each set of inner slide rails 306 is slidably connected with an inner slider 310. The two ends of the inner slide plate 307 are respectively fixedly connected to different inner sliders 310. The upper rotating seat 308 is symmetrically fixedly connected to the bottom surface of the inner slide plate 307.

[0058] When the inner slide plate 307 is stationary at a certain position, the opening and closing of the box cover 103 allows the rotating connecting rod 309 to form a screw connection between the upper rotating seat 308 and the upper connecting horizontal plate 305, thereby driving the synchronous lifting and lowering movement of the cathode slide column 302. After the box cover 103 is opened to the position, the cathode plate 303 is lifted to the position, making it convenient to place the sample. After the box cover 103 is closed to the position, the cathode plate 303 is immersed in the silicone oil in the heat-insulated inner oil tank shell 201, which facilitates the formation of rapid polarization operation.

[0059] The specific structure of the second adjustment component 4 is as follows: Figure 5 As shown, the inner screw seat 403 is fixedly connected to the middle of the rear side of the inner cavity of the cover 103, and the outer screw seat 404 is connected to the middle of the front side of the cover 103. One end of the adjusting screw 402 is rotatably connected to the inner screw seat 403, and the other end is rotatably connected to the outer screw seat 404.

[0060] The lead screw slide 401 is fixedly connected to the middle of the bottom surface of the inner slide plate 307.

[0061] The specific structure of the upper anode column assembly 5 is as follows: Figure 6 As shown, the lifting slide 501 is located at the top of the main body of the box cover 103, and the lifting slide column 502 is slidably connected in the lifting slide 501.

[0062] The top of the array of lifting slide columns 502 is fixedly connected to a top connecting plate 503, and a lifting electric cylinder 504 is installed and fixed on the outer top surface of the box cover 103. The telescopic rod of the lifting electric cylinder 504 is fixedly connected to the middle of the bottom end of the top connecting plate 503, which can realize the automatic lifting function of the top connecting plate 503 and the lifting slide column 502.

[0063] The main body of the built-in plate 505 has an array of upper positioning holes 506, and an anode pressure column 507 can be installed in each set of upper positioning holes 506.

[0064] The lifting slide column 502 is made of non-conductive ceramic material, and the built-in plate 505 is made of conductive copper alloy material. The anode pressure column 507 installed in any set of upper positioning holes 506 can be energized through the built-in plate 505.

[0065] Preferably, the two ends of the rear axle 104 are also connected to the rear side wall of the bottom box 101 by a linkage limiting member 6, which not only allows the box cover 103 to be in a normally closed state, but also, through the lateral movement of the passive rack 603 as the box cover 103 opens and closes, can also safely limit the upward lifting position of the cathode plate 303; the passive gear 601 is symmetrically fixedly connected to the two ends of the rear axle 104, and the rear side wall of the bottom box 101 is symmetrically provided with passive slides 602, the passive rack 603 is slidably connected in the passive slides 602, and the passive rack 603 on the same side meshes with the passive gear 601; The inner rack connecting plate 604 is fixedly connected to the front end of the driven rack 603, and the outer rack connecting plate 605 is fixedly connected to the rear end of the driven rack 603. A top spring 606 is also connected between the front side of the outer rack connecting plate 605 and the rear side of the bottom box 101. Under the elastic support force of the top spring 606 on the outer rack connecting plate 605, when there is no external force pushing the box cover 103, the driven rack 603 can be in the rearmost position. Thus, by utilizing the transmission formed by the driven rack 603 and the driven gear 601, the box cover 103 connected to the rear axle 104 can be in a normally closed state.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
