Description

Technical Field

[0001] The invention belongs to the technical field of medical material preparation, in particular to a preparation device for a polyurethane fluorescent luminescent medical material. Background Art

[0002] In recent years, due to the continuous development of society and the progress of science and technology, the demand for functional materials has been increasing worldwide, especially biopolymer materials. Polyurethane, as an important biopolymer material, has always been a hot topic of research and plays a vital role in many artificial organs and medical devices. The main properties of polyurethane are excellent anticoagulant properties, toxicity test results meet medical requirements, good biocompatibility in clinical applications, no teratogenic effect, no allergic reaction, and excellent toughness and elasticity, good processing performance, and various processing methods. It is the preferred material for making various medical elastomer products; and it has excellent wear resistance, soft touch, moisture resistance, resistance to a variety of chemicals, and can be sterilized by common methods. Therefore, polyurethane, as a general polymer, has a wide range of uses, such as self-healing materials, shape memory materials, medical materials, acoustic materials, etc., but because there is no π-conjugated chromophore group as a chain extension in the polymer chain, their luminescent properties and further optoelectronic applications are mostly ignored. Therefore, the introduction of chromophores in the polyurethane chain can make the polyurethane molecules exhibit fluorescent properties. When preparing polyurethane fluorescent luminescent medical materials, an oil bath is often used to place the prepared solution in the oil bath for sufficient reaction in preparation for subsequent preparation operations.

[0003] The Chinese patent announcement number CN209222087 U discloses a device for preparing polyurethane, including a reactor. The reactor includes a bottle body and a bottle cap, an extended edge is formed on the bottle body, a connecting edge is formed on the bottle cap corresponding to the extended edge, a sealing ring is fixed at the matching position between the extended edge and the connecting edge, and a buckle device fixed with the extended edge is installed on the connecting edge. The present invention has the following advantages and effects: This scheme utilizes a new mechanical structure, a sealing ring is installed in the extended edge on the bottle body and the corresponding connecting edge on the bottle cap, which has a sealing effect on the bottle body, and further the buckle device fixed on the connecting edge and the extended edge has a reinforcing effect on the installation of the sealing ring, thereby improving the sealing of the sealing ring, thereby avoiding the problem of the reaction solution overflowing from the gap between the reaction bottle and the bottle cap and causing the heating sleeve to be corroded.

[0004] The device achieves the preparation of polyurethane, but it only makes improvements on the reaction receiving cup, which is not sufficient in the design of the entire process of preparing polyurethane. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a preparation device for a polyurethane fluorescent luminescent medical material, so as to realize the whole process of preparing the polyurethane fluorescent luminescent medical material through the coordination of the overall structure.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a preparation device for polyurethane fluorescent luminescent medical material, comprising an oil bath pot, the oil bath pot comprising a main body, a working pot is arranged on the top of the main body, a placement pad is arranged in the working pot, a receiving cup is placed on the placement pad, a ground-mouth sealing plug is arranged at the opening of the receiving cup, a working mechanism is arranged on one side of the oil bath pot, a sedimentation box is arranged on the side of the oil bath pot away from the working mechanism, a material passing pipe and a feeding pipe are arranged on the top of the sedimentation box, the material passing pipe is connected with the sedimentation box, the end of the material passing pipe away from the sedimentation box extends into the working pot and is connected with the receiving cup, a pump assembly and a one-way valve are arranged on the material passing pipe, a sealing cover is arranged on the feeding pipe, and the sedimentation box is opened on the side away from the oil bath pot, and a closing plate is arranged on the opening.

[0007] The principle and beneficial effects of the basic scheme are: during operation, aromatic diisocyanate, polyether diol, dihydroxy organic molecules with carboxyl groups, dihydroxy fluorescent substances and dihydroxy organic molecules with secondary amine or tertiary amine groups are placed in a receiving cup, and then solvent dimethylformamide, dimethyl sulfoxide or N-methylpyrrolidone are added. After adding the solvent, a catalyst is added to the receiving cup, and then pipes are inserted into the two pipes of the ground-mouth sealing plug respectively, one side of the two pipes continuously inputs nitrogen, and the other pipe is placed in water at one end away from the ground-mouth sealing plug, and then the oxygen in the receiving cup is discharged and the receiving cup is filled with nitrogen, so that the prepared liquid in the receiving cup is protected by nitrogen.

[0008] Then, the oil bath is started by the working mechanism of the oil bath, and the working temperature in the oil bath is adjusted to a suitable temperature. The prepared solution will react in the oil bath, and after reacting for a certain period of time, a chain extender is added to make the prepared solution react. Then, after adding the chain extender, the prepared solution will react in the oil bath for a certain period of time. After the reaction is completed, the oil bath is closed by the working mechanism of the oil bath. At the same time, after closing the oil bath, the prepared solution is not output immediately, but is cooled to a certain temperature before output. When outputting the prepared solution, first open the one-way valve and start the pump assembly at the same time. Then, under the drive of the pump assembly, the prepared solution in the receiving cup is input into the precipitation box. After the prepared liquid is input into the precipitation box, open the closing cover, and then add the precipitation solvent into the precipitation box through the feed pipe to make the prepared solution precipitate.

[0009] After the prepared solution reacts, a solid material will be formed, and then the sealing plate is taken out to open the opening, and then the prepared polyurethane fluorescent luminescent medical material is sent to the drying mechanism, and finally the polyurethane fluorescent luminescent medical material can be made and used. When preparing the polyurethane fluorescent luminescent medical material, the temperature and time during preparation can be more accurately grasped by reacting in an oil bath pot, and because the temperature rise values ​​of different oils are different, it is beneficial to grasp the temperature condition of the prepared solution during the reaction according to different oil properties. At the same time, because of the design of the ground mouth sealing plug, the oxygen in the receiving cup can be discharged, so that the nitrogen protection solution is in a state of reaction, so as to avoid the solution reacting, and then the oxygen can react and make the preparation effect poor. And by directly inputting the prepared solution from the material pipeline into the sedimentation box for sedimentation operation, on the one hand, it can facilitate the experimental operation, avoid the situation of moving the receiving cup to multiple places, etc., so that unexpected situations are sent, thereby affecting the preparation of the material, and on the other hand, the prepared solution is precipitated in the sedimentation box, so that the prepared material can be easily taken out. Therefore, in general, through the synergistic effect of the overall structure, the device realizes the preparation of polyurethane fluorescent luminescent medical materials.

[0010] Furthermore, an insulation plate is provided on the outside of the main body, a first transition plate is fixedly connected to the bottom of the insulation plate, the first transition plate is fixedly connected to the oil bath pot on the side away from the insulation plate, a second transition plate is fixedly connected to the top of the insulation plate, and the second transition plate is fixedly connected to the oil bath pot on the side away from the insulation plate.

[0011] The principle and beneficial effects of the basic solution are: because one end of the insulation board is fixedly connected to the oil bath pot, and the other end is fixedly connected to the oil bath pot through the transition plate, a certain cavity is left between the oil bath pot and the insulation board. Therefore, when the oil bath pot releases a large amount of heat through a high-temperature reaction, most of the heat energy will be reduced under the transition of the cavity, so only a small amount of heat energy is transferred to the insulation board, thereby avoiding the high temperature released by the oil bath pot to its surroundings to a certain extent, thereby reducing the possibility of operators being burned when touching the oil bath pot with their hands.

[0012] Furthermore, support plates are provided in both the length direction and the width direction of the bottom of the main body.

[0013] The principle and beneficial effects of the basic solution are: when the device needs to be lifted, the design of the bottom support plate can be convenient for human hands to hold it, which is more suitable for actual experimental needs, and the design of the support plate can reduce the area of ​​heat transferred to the floor of the oil bath when the oil bath is heated to too high a temperature, thereby avoiding damage to the floor due to the influence of temperature.

[0014] Furthermore, a rubber layer is provided on the support plate.

[0015] The principle and beneficial effect of the basic solution are: the design of the rubber layer can increase the friction between the support plate and the ground and the human hand, so that the oil bath pot can be more firmly located on the ground, and it is also convenient for operators to move the oil bath pot.

[0016] Furthermore, a plurality of anti-skid grooves are provided on the rubber layer.

[0017] The principle and beneficial effect of the basic solution are: the design of the anti-skid groove can play a certain anti-skid role, which can facilitate the operator to move the oil bath pot and other operations. And to a certain extent, it can prevent the operator from slipping the oil bath pot due to hand slippage and other reasons.

[0018] Furthermore, hanging ears are provided on both sides of the body.

[0019] The principle and beneficial effects of the basic solution are: the design of the hanging ear makes it easy for the operator to move the oil bath pot by hand, and at the same time, when the oil bath pot is heated at high temperature, the operator can adjust the position of the oil bath pot by touching the hanging ear with his hand, thereby avoiding the problem of being burned by directly touching the oil bath pot with his hand.

[0020] Furthermore, the ear hook is provided with anti-slip grooves.

[0021] The principle and beneficial effect of the basic solution are: the design of the anti-slip pattern can increase the friction when the hand contacts the ear, thereby reducing the possibility of the operator's hand slipping.

[0022] Furthermore, the side of the placement pad close to the receiving cup is in an arc shape that fits the bottom of the receiving cup, and a plurality of clamping blocks are provided on the placement pad.

[0023] The principle and beneficial effects of the basic solution are: the design of the clamping block can make the receiving cup more firmly fixed in the oil bath pot, avoiding the receiving cup from tipping over in the oil bath pot, and the arc-shaped placement pad can make the receiving cup and the placement pad fit more closely.

[0024] Furthermore, the receiving cup includes a cup body with an opening, the bottom of the cup body has a protrusion facing the opening, the protrusion includes a metal part and a connecting part integrally manufactured with the cup body, the metal part is fixedly connected to the connecting part, and the metal part includes a metal folding strip, an air receiving hole is provided between the opening and the protrusion, and the surface of the air receiving hole is covered with a fastener.

[0025] Beneficial effect: When the heating is completed, in order to promote the cooling and rapid shaping of the material, the receiving cup is pressed tightly against the table to facilitate the sealing of the channel hole. Then the technical solution can open the air hole, wherein the fastening parts of the air hole include but are not limited to plugs, thereby covering the opening of the cup body and evacuating the cup body to form a vacuum, thereby promoting the material to fit tightly between adjacent protrusions. At the same time, due to the reduction in pressure in the receiving cup, due to the presence of the channel hole, part of the oil on the surface of the material will be immersed in the surface of the material or in the receiving cup during actual use. At this time, the receiving cup is separated from the oil bath.

[0026] After condensation, part of the oil adheres to the surface of the material or is in the receiving cup. Therefore, the boiling point of the oil will gradually decrease during the pressure reduction process. Therefore, under the residual heat of the receiving cup, the oil vapor will vaporize quickly, and the vaporized oil will slide over the surface of the material easily. At the same time, the oil vapor in the channel hole will also liquefy, and the oil will fall in the channel hole.

[0027] Furthermore, a channel hole is provided at the connection between the protrusion and the metal folding strip, and the interior of the channel hole has a concave baffle, which gradually converges along the channel hole to the bottom of the cup body, and a drainage groove is processed on the surface of the metal folding strip, and the lowest point of the drainage groove with gravitational potential energy faces the channel hole.

[0028] Beneficial effect: During the heating process, the hot air in the oil bath enters along the channel hole, thereby accelerating the heating and forming of the material in the receiving cup. Subsequently, as the hot air impacts the metal folding strip each time, the condensate formed will slide down the drainage groove into the channel hole (minimum energy consumption principle). At the same time, the oil splashing in the oil bath will be blocked by the concave baffle to keep the interior clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The embodiment is basically as shown in the attached Figure 1 and Figure 2 As shown: a preparation device for polyurethane fluorescent luminescent medical material, including an oil bath pot, the oil bath pot includes a body 1, and ears 2 are arranged on both sides of the body 1, and anti-slip patterns are arranged on the ears 2. A working pot 10 is arranged on the top of the body 1, and a placement pad 15 is arranged in the working pot 10. A receiving cup 17 is placed on the placement pad 15, and a ground sealing plug 18 is arranged at the opening of the receiving cup 17. The placement pad 15 is close to the receiving cup 17 and is in an arc shape that fits the bottom of the receiving cup 17, and a plurality of blocks 16 are arranged on the placement pad 15. A working mechanism 9 is arranged on one side of the oil bath pot, and a sedimentation box 6 is arranged on the side of the oil bath pot away from the working mechanism 9. A material passing pipeline 3 and a feeding pipeline 4 are arranged on the top of the sedimentation box 6, and the material passing pipeline 3 is connected with the sedimentation box 6. One end of the material passing pipeline 3 away from the sedimentation box 6 extends into the working pot 10 and is connected with the receiving cup 17, a pump assembly and a one-way valve are arranged on the material passing pipeline 3, and a sealing cover 5 is arranged on the feeding pipeline 4. The sedimentation box 6 is open on the side away from the oil bath pot, and a closing plate 7 is arranged on the opening. Specifically: the model of the oil bath pot is preferably HH-WO, and the pump assembly is preferably a water pump.

[0035] The specific implementation process is as follows: during operation, aromatic diisocyanate, polyether diol, dihydroxy organic molecules with carboxyl groups, dihydroxy fluorescent substances and dihydroxy organic molecules with secondary amine or tertiary amine groups are placed in the receiving cup 17, and then solvent dimethylformamide, dimethyl sulfoxide or N-methylpyrrolidone are added. After adding the solvent, a catalyst is added to the receiving cup 17, and then pipes are inserted into the two pipes of the ground-mouth sealing plug 18 respectively, one side of the two pipes continuously inputs nitrogen, and the other pipe is placed in water at one end away from the ground-mouth sealing plug 18, and then the oxygen in the receiving cup 17 is discharged and the receiving cup 17 is filled with nitrogen, so that the prepared liquid in the receiving cup 17 is protected by nitrogen.

[0036] Then, the oil bath is started by the working mechanism 9 of the oil bath, and the working temperature in the oil bath is adjusted to a suitable temperature. The prepared solution will react in the oil bath, and after reacting for a certain period of time, a chain extender is added to make the prepared solution react. Then, after adding the chain extender, the prepared solution will react in the oil bath for a certain period of time. After the reaction is completed, the oil bath is closed by the working mechanism 9 of the oil bath. At the same time, after closing the oil bath, the prepared solution is not output immediately, but is cooled to a certain temperature before output. When outputting the prepared solution, first open the one-way valve and start the pump assembly at the same time. Then, under the drive of the pump assembly, the prepared solution in the receiving cup 17 is input into the precipitation box 6. After the prepared liquid is input into the precipitation box 6, open the closing cover, and then add the precipitation solvent into the precipitation box 6 through the feed pipe 4 to make the prepared solution perform precipitation operation.

[0037] After the prepared solution reacts, a solid material will be formed, and then the sealing plate 7 is taken out to open the opening, and then the prepared polyurethane fluorescent medical material is sent to the drying mechanism, and finally the polyurethane fluorescent medical material can be made and set aside. When preparing polyurethane fluorescent medical materials, the temperature and time of the preparation can be more accurately controlled by reacting in an oil bath, and because different oils have different heating values, different oil properties can be used to control the temperature conditions of the prepared solution during the reaction. At the same time, due to the design of the ground-mouth sealing plug 18, the oxygen in the receiving cup 17 can be discharged, so that the nitrogen protects the solution during the reaction to avoid the solution reacting with oxygen and thus causing poor preparation results. In addition, by directly inputting the prepared solution from the feed pipe 3 into the sedimentation box 6 for sedimentation, on the one hand, it is convenient for experimental operations and avoids moving the receiving cup 17 to multiple locations, which may cause unexpected situations and affect the preparation of the material. On the other hand, the prepared solution is precipitated in the sedimentation box 6, which makes it easy to take out the prepared material. In general, through the synergistic effect of the overall structure, the device realizes the preparation of polyurethane fluorescent medical materials.

[0038] Example 2

[0039] The difference from the above embodiment is that a thermal insulation plate 11 is provided on the outside of the main body 1, a first transition plate 13 is fixedly connected to the bottom of the thermal insulation plate 11, the first transition plate 13 is fixedly connected to the oil bath on the side away from the thermal insulation plate 11, a second transition plate 12 is fixedly connected to the top of the thermal insulation plate 11, and the second transition plate 12 is fixedly connected to the oil bath on the side away from the thermal insulation plate 11.

[0040] The specific implementation process is as follows: because one end of the insulation plate 11 is fixedly connected to the oil bath pot, and the other end is fixedly connected to the oil bath pot through the transition plate, a certain cavity is left between the oil bath pot and the insulation plate 11. Therefore, when the oil bath pot undergoes a high-temperature reaction and releases a large amount of heat, most of the heat energy will be reduced under the transition of the cavity, so only a small amount of heat energy is transferred to the insulation plate 11, thereby avoiding the high temperature released by the oil bath pot to its surroundings to a certain extent, thereby reducing the possibility of operators being scalded when touching the oil bath pot with their hands.

[0041] Example 3

[0042] The difference from the above embodiment is that a support plate 8 is provided in both the length direction and the width direction of the bottom of the body 1, a rubber layer is provided on the support plate 8, and a plurality of anti-slip grooves are provided on the rubber layer.

[0043] The specific implementation process is as follows: when the device needs to be lifted, the design of the bottom support plate 8 can be convenient for human hands to carry, which is more suitable for actual experimental needs, and the design of the support plate 8 can reduce the area of ​​heat transfer to the floor of the oil bath when the oil bath is heated to too high a temperature, thereby preventing the floor from being damaged by the temperature. At the same time, the design of the rubber layer can increase the friction between the support plate 8 and the ground and the human hand, so that the oil bath can be more firmly located on the ground, and it is also convenient for operators to move the oil bath. And the design of the anti-skid groove can play a certain anti-skid role, which can facilitate operators to move the oil bath. And to a certain extent, it can prevent the operator from slipping the oil bath due to hand slips and other reasons.

[0044] Example 4

[0045] Please refer to Figure 3 The difference between this embodiment and the above embodiment is that: the receiving cup 17 includes a cup body with an opening, the bottom of the cup body has a protrusion 19 facing the opening, the protrusion 19 includes a metal part and a connecting part made integrally with the cup body, the metal part is fixedly connected to the connecting part, and the metal part includes a metal folding strip 20, an air receiving hole 21 is provided between the opening and the protrusion 19, and the surface of the air receiving hole 21 is covered with a fastener 22. A channel hole 23 is provided at the connection between the protrusion 19 and the metal folding strip 20, and the inside of the channel hole 23 is provided with a concave baffle 24, and the baffle 24 gradually converges along the bottom of the cup body of the channel hole 23, and a drainage groove 25 is processed on the surface of the metal folding strip 20, and the lowest point of the gravitational potential energy of the drainage groove 25 faces the channel hole 23.

[0046] The specific implementation process is as follows: during the heating process, the hot air in the oil bath enters along the channel hole 23, thereby accelerating the heating and forming of the material in the receiving cup 17. Subsequently, since the hot air will impact the metal folding strip 20 each time, the condensate formed will slide down along the drainage groove 25 into the channel hole 23 (minimum energy consumption principle). At the same time, the oil splashing in the oil bath will be blocked by the concave baffle 24 to keep the interior clean.

[0047] When the heating is completed, in order to promote the cooling and rapid shaping of the material, the receiving cup 17 is pressed tightly against the table to seal the channel hole 23. Then the technical solution can open the air receiving hole 21, wherein the fastening piece 22 of the air receiving hole 21 includes but is not limited to a plug, thereby covering the opening of the cup body and evacuating the cup body to form a vacuum, thereby promoting the material to fit tightly between adjacent protrusions 19. At the same time, due to the reduction in pressure in the receiving cup 17, due to the existence of the channel hole 23, part of the oil will be immersed on the surface of the material or in the receiving cup 17 during actual use. At this time, the receiving cup 17 is separated from the oil bath.

[0048] After condensation, part of the oil adheres to the surface of the material or is in the receiving cup 17. Therefore, the boiling point of the oil will gradually decrease during the pressure reduction process. Therefore, under the residual heat of the receiving cup 17, the oil vapor will vaporize quickly, and the vaporized oil will slide over the surface of the material easily. At the same time, the oil vapor in the channel hole 23 will also liquefy, and the oil will fall in the channel hole 23.
