Description

Technical Field

[0001] This invention relates to the field of thermosetting devices for balloon catheters, and in particular to an automatic thermosetting device for processing medical balloon catheters. Background Technology

[0002] A balloon catheter is an interventional medical device primarily used to dilate narrowed or blocked blood vessels or cavities, or to assist in the implantation of stents. Its core structure includes an inflatable balloon, a catheter body, and a guidewire lumen. The balloon is dilated by injecting contrast agent or saline through a pressure pump. It is widely used clinically in cardiovascular interventional therapy, peripheral vascular disease, and the clearing of non-vascular cavities.

[0003] Currently, thermosetting is a necessary process in balloon catheter manufacturing, and there are already publicly available technical examples of this technology. However, after combining the existing technical disclosures with its own production experience, the applicant found that the preparation work before the heat treatment of balloon catheters in the existing technology is mostly done manually in multiple steps. For example, in the patent document CN208035105U, an automatic thermosetting device for balloon catheters, the technical solution requires the tubular structure other than the balloon tube body to be wound and limited first. As a result, it is inefficient and increases the labor intensity of the user, with many limitations. Summary of the Invention

[0004] This application proposes an automatic thermosetting device for processing medical balloon catheters, which solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic thermosetting device for processing medical balloon catheters, including a support frame, a conveying device installed on the top of the support frame, the conveying device including a conveyor belt, a thermosetting relief groove and several trapezoidal grooves opened in the conveyor belt, and the several trapezoidal grooves are arranged in parallel from front to back along one side of the thermosetting relief groove and cooperate with the internal space of the thermosetting relief groove to form several clamping spaces, a balloon catheter is fitted in the clamping space, and the balloon structure inside the balloon catheter is located inside the thermosetting relief groove; The top of the thermosetting relief groove is fitted with a thermosetting treatment cover installed on the top of the support frame. Inside the thermosetting treatment cover are a clamping heating device and a bidirectional engagement mechanism for holding the balloon catheter set inside the thermosetting relief groove. The clamping heating device includes two electric heating plates aligned with the thermosetting relief groove, and the two output structures inside the bidirectional engagement mechanism drive the two electric heating plates to clamp or move away from each other toward the thermosetting relief groove.

[0006] When the clamping heating device, bidirectional meshing mechanism, thermosetting treatment cover, and support frame are used in combination, multiple balloon catheters conveyed to a designated position by the conveyor belt will undergo automated thermosetting treatment by the two electric heating plates inside the clamping heating device, which will individually mount the balloon tube structures within the multiple balloon catheters and provide independent space. This improves production efficiency. For multiple balloon catheters that have been thermoset and whose two electric heating plates have moved apart, the conveyor belt can further guide them, fully meeting the user's need for fixed-point collection.

[0007] Preferably, both sides of the conveyor belt are friction-driven connected to support shafts, and the ends of the support shafts are fitted to the corresponding side walls of the top of the support frame.

[0009] Preferably, the bidirectional meshing mechanism includes two gear assemblies and a first electric push rod. The front and rear ends of the gear assemblies are respectively meshed and driven by a first straight tooth plate and a second straight tooth plate. A curved rod fixed to the bottom surface of the thermosetting cover is mounted in the middle of the gear assembly through a bearing. One end of the top of the first straight tooth plate and one end of the bottom of the second straight tooth plate are respectively driven and connected to one end of two linkage plates. A U-shaped frame is movably sleeved inside the top of the thermosetting cover. The end of the U-shaped frame passes through the linkage plate of the outer electric heating plate at the top of the conveyor belt and is fixed to the surface of the linkage plate of the inner electric heating plate at the inside of the conveyor belt.

[0010] Preferably, the housing of the first electric push rod is fitted inside the top of the thermosetting cover, and the output end of the first electric push rod is connected to the top of the external electric heating plate located at the top of the conveyor belt. Preferably, a first spring is fitted on both ends of the U-shaped frame, and the two ends of the first spring are respectively fixed to the top surface of the thermosetting cover and the surface of the U-shaped frame.

[0011] Preferably, a linkage airbag assembly is provided between the top of the electric heating plate located outside the top of the conveyor belt and the inner wall of the top of the thermosetting treatment hood. The linkage airbag assembly includes a folding airbag, the top of which is provided with an air inlet and a conduit. The top and bottom of the folding airbag are respectively fixed to the inner wall of the top of the thermosetting treatment hood and the top surface of the corresponding electric heating plate.

[0012] Preferably, an extension support plate and a preheating hood are provided on one side of the thermosetting hood. The extension support plate is installed between the surface of the preheating hood and one side surface of the thermosetting hood, and one end of the conduit is connected to the preheating hood.

[0013] Preferably, the number of the linkage airbag assembly and the duct is the same, and each is set to two. One end of each of the two ducts penetrates one side wall of the thermosetting cover and is then respectively fitted into the front end and rear end of the top of the preheating cover.

[0014] Preferably, a top-pressure extension assembly is fitted inside one side of the conveyor belt. The top-pressure extension assembly includes a support plate that is movably fitted inside the conveyor belt. I-shaped shafts are snapped into the front and rear ends of the support plate. A second electric push rod installed on the top surface of the support frame is driven to the bottom of the I-shaped shaft. An arc-shaped top rod is fixed to the top of the support plate.

[0015] Preferably, a third spring is fitted around one end of the I-shaped shaft, and the two ends of the third spring are respectively fixed to the bottom surface of the support plate and the surface of one end of the I-shaped shaft.

[0016] Preferably, a sensing plate is installed on the surface of the rear end of the conveyor belt, and a displacement sensor aligned with the sensing plate is provided at the rear end of the middle part of the support frame.

[0017] In summary, the present invention has the following beneficial effects: 1. When the clamping heating device, bidirectional meshing mechanism, thermosetting treatment cover, and support frame are combined, multiple balloon catheters conveyed to a designated position by the conveyor belt will be automatically thermoset one by one by the two electric heating plates inside the clamping heating device through the bidirectional meshing mechanism, improving production efficiency. For multiple balloon catheters that have been thermoset and whose two electric heating plates have separated, the conveyor belt can further guide them, fully meeting the user's need for fixed-point collection.

[0018] 2. The linkage airbag assembly can simultaneously utilize the kinetic energy of the corresponding electric heating plate to output airflow without interfering with the lifting and lowering operation of the corresponding electric heating plate. Then, the hot air generated by the overflow waste heat during the heating process of the two electric heating plates inside the thermosetting treatment hood enters the linkage airbag assembly through the air inlet at the top of the linkage airbag assembly. Then, when the corresponding electric heating plate moves up and resets, the linkage airbag assembly contracts and folds synchronously, and then the hot air inside itself is guided to the preheating hood through the set conduit. Then, the preheating hood guides the air to the balloon tube structure with multiple balloon conduits set in another thermosetting clearance groove for preheating treatment.

[0019] 3. By using the top pressure extension component as an unloading auxiliary condition, the output end of the second electric push rod can be used to lift the arc-shaped top rod through the I-shaped shaft, the third spring and the support plate until the arc-shaped top rod moves up inside the conveyor belt and presses against the top structure of the conveyor belt. This causes the bottom of multiple trapezoidal grooves to be pressed, expanding their own top open structure, making it convenient for users to extract the balloon catheter and improving work efficiency.

Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described in conjunction with preferred embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-6An automatic thermosetting device for processing medical balloon catheters includes a support frame 1. A conveying device is installed on the top of the support frame 1. The conveying device includes a conveyor belt 2. A sensing plate is installed on the surface of the rear end of the conveyor belt 2. A displacement sensor 21 aligned with the sensing plate is set at the rear end of the middle part of the support frame 1. Both sides of the conveyor belt 2 are frictionally connected to support shafts, and the ends of the support shafts are fitted to the corresponding side walls of the top of the support frame 1. A brake servo motor 15 is installed on one side of the top of the support frame 1 and is connected to one end of one of the support shafts. By utilizing the combined transmission effect of the brake servo motor 15 and the two support shafts, the conveyor belt 2 can be made to rotate cyclically, thereby meeting the subsequent continuous material feeding requirements. The conveyor belt 2 has a thermosetting relief groove 3 and several trapezoidal grooves 4. The trapezoidal grooves 4 are arranged in parallel from front to back along one side of the thermosetting relief groove 3 and cooperate with the internal space of the thermosetting relief groove 3 to form several clamping spaces. A balloon catheter 5 is installed in the clamping space, and the balloon structure in the balloon catheter 5 is located inside the thermosetting relief groove 3. The top of the thermosetting relief groove 3 is fitted with a thermosetting treatment cover 6 installed on the top of the support frame 1. The thermosetting treatment cover 6 is equipped with a clamping heating device and a bidirectional engagement mechanism that can fit the balloon catheter 5 inside the thermosetting relief groove 3. The clamping heating device includes two electric heating plates 7 aligned with the thermosetting relief groove 3, and the two output structures inside the bidirectional engagement mechanism drive the two electric heating plates 7 to clamp or move away from each other towards the thermosetting relief groove 3. Each of the two electric heating plates 7 has several matching grooves 8, and the space between the two matching grooves 8 aligned vertically forms a thermosetting space, which satisfies the targeted fitting and thermosetting treatment of the balloon structure inside the balloon catheter 5. The surfaces of the two electric heating plates 7 are fixed with linkage plates, which provide the structural conditions for the transmission connection of the subsequent related structures. The two electric heating plates 7 are located on the top outside of the conveyor belt 2 and are movably sleeved inside the conveyor belt 2, respectively, to avoid structural operation interference. The bidirectional meshing mechanism includes two gear assemblies 10 and a first electric push rod 9. The front and rear ends of the gear assemblies 10 are respectively meshed and connected to a first straight tooth plate 11 and a second straight tooth plate 12. A curved rod fixed to the bottom surface of the thermosetting cover 6 is mounted in the middle of the gear assembly 10 through a bearing. One end of the top of the first straight tooth plate 11 and one end of the bottom of the second straight tooth plate 12 are respectively connected to one end of the two linkage plates. A U-shaped frame 13 is movably sleeved in the top of the thermosetting cover 6. The end of the U-shaped frame 13 passes through the linkage plate of the outer electric heating plate 7 at the top of the conveyor belt 2 and is fixed on the surface of the linkage plate of the electric heating plate 7 inside the conveyor belt 2. This satisfies the alternating displacement adjustment of the two electric heating plates 7 during operation and meets the requirements of continuous thermosetting. The housing of the first electric push rod 9 is fitted inside the top of the thermosetting cover 6, and the output end of the first electric push rod 9 is connected to the top of the outer electric heating plate 7 located on the top of the conveyor belt 2. The first electric push rod 9 can serve as a power output condition, enabling the two electric heating plates 7 to automatically approach or separate under the transmission of the bidirectional meshing mechanism. Both ends of the U-shaped frame 13 are fitted with first springs 14, and the two ends of the first springs 14 are respectively fixed to the top surface of the thermosetting cover 6 and the surface of the U-shaped frame 13, thereby providing a buffer condition for the close contact between the two electric heating plates 7, avoiding hard impacts and extending service life.

[0024] In use, multiple balloon catheters 5 are nested sequentially in multiple parallel thermosetting kit spaces, and the balloon tube structure inside the balloon catheter 5 is fitted inside the thermosetting relief groove 3. Then, the brake servo motor 15 is started, and the output end of the brake servo motor 15 drives two support shafts, which in turn causes the conveyor belt 2 to drive multiple balloon catheters 5 to perform automatic horizontal displacement until the sensing plate is aligned with the displacement sensor 21 in the open state. Then the brake servo motor 15 stops, and at this time the thermosetting relief groove 3 will be located between the two electric heating plates 7 and aligned. Next, the first electric actuator 9 is activated, and its output drive automatically moves the corresponding electric heating plate 7 and the first spur gear plate 11 downwards. Simultaneously, under the synchronous meshing transmission of the gear assembly 10, the second spur gear plate 12 moves close to the first spur gear plate 11. This causes the two electric heating plates 7 to move close together until multiple sets of vertically aligned matching grooves 8 fit the corresponding balloon tubes inside the balloon catheters 5. After completion, the two electric heating plates 7 are activated to synchronously heat-set the balloon tube structures inside the multiple balloon catheters 5. After a certain period, the first electric actuator 9 is turned off, and the first electric actuator... The output end of push rod 9 drives the corresponding electric heating plate 7 and the first spur tooth plate 11 to automatically move upward and reset. At the same time, under the synchronous meshing transmission of gear assembly 10, the second spur tooth plate 12 drives another electric heating plate 7 to move away from the first spur tooth plate 11 and reset until the two electric heating plates 7 are in their initial positions. Then, the brake servo motor 15 is restarted, so that the conveyor belt 2 drives the two support shafts at the output end to drive multiple thermosetting balloon catheters 5 to automatically move away from the thermosetting cover 6. After reaching a safe distance, the processed balloon catheters 5 are extracted one by one. Then, the above steps are repeated.

[0025] like Figures 5-7A linkage airbag assembly 16 is provided between the top of the electric heating plate 7 located outside the top of the conveyor belt 2 and the inner wall of the top of the thermosetting treatment hood 6. The linkage airbag assembly 16 includes a folded airbag 161. The top of the folded airbag 161 is provided with an air inlet and a conduit 20. The top and bottom of the folded airbag 161 are fixed to the inner wall of the top of the thermosetting treatment hood 6 and the top surface of the corresponding electric heating plate 7, respectively. The linkage airbag assembly 16 can simultaneously use the kinetic energy of the corresponding electric heating plate 7 to output airflow without interfering with the lifting operation of the corresponding electric heating plate 7. An extension support plate 17 and a preheating hood 18 are provided on one side of the thermosetting treatment hood 6. The extension support plate 17 is installed between the surface of the preheating hood 18 and one side surface of the thermosetting treatment hood 6. One end of the conduit 20 is connected to the preheating hood 18.

[0026] In use, the number of thermosetting relief grooves 3 shall not be less than two. The linkage airbag assembly 16 shall be able to simultaneously utilize the kinetic energy of the corresponding electric heating plate 7 to output airflow without interfering with the lifting and lowering operation of the corresponding electric heating plate 7. Specifically, when the electric heating plate 7 corresponding to the linkage airbag assembly 16 moves down, the linkage airbag assembly 16 expands its internal air synchronously. The hot air inside the thermosetting treatment cover 6 caused by the overflow waste heat during the heating process of the two electric heating plates 7 enters the linkage airbag assembly 16 through the air inlet at the top of the linkage airbag assembly 16. Then, when the corresponding electric heating plate 7 moves up and resets, the linkage airbag assembly 16 will synchronously contract and fold, and then guide the hot air inside its own body to the preheating cover 18 through the conduit 20. Then, the preheating cover 18 guides the multiple balloon conduits 5 set in another thermosetting relief groove 3 for preheating treatment. During the reciprocating suction and delivery process of the linkage airbag assembly 16, the air inside the thermosetting treatment hood 6 will further accelerate the convection with the cold air outside, thereby indirectly cooling the two continuously operating electric heating plates 7 and extending the service life of the two electric heating plates 7.

[0027] like Figures 5-7 The number of linked airbag components 16 and ducts 20 is the same, and each is set to two. One end of each of the two ducts 20 passes through one side wall of the thermosetting cover 6 and is then respectively fitted into the front end and rear end of the top of the preheating cover 18.

[0028] In order to ensure the uniform flow of hot air inside the preheating hood 18 during use, two sets of air supply structures are formed by two linked airbag components 16 and two ducts 20 and are respectively set at the front and rear ends of the preheating hood 18, which reduces the probability of large temperature differences in the cooling space.

[0029] like Figures 5-8A top-pressure extension assembly 19 is fitted inside one side of the conveyor belt 2. The top-pressure extension assembly 19 includes a support plate 191 that is movably fitted inside the conveyor belt 2. I-shaped shafts 192 are snapped into the front and rear ends of the support plate 191. A second electric push rod 194 is connected to the bottom of the I-shaped shaft 192 and installed on the top surface of the support frame 1. An arc-shaped top rod 195 is fixed to the top of the support plate 191. A third spring 193 is fitted on the outer side of one end of the I-shaped shaft 192. The two ends of the third spring 193 are respectively fixed to the bottom surface of the support plate 191 and the surface of one end of the I-shaped shaft 192.

[0030] When in use, the need for convenience in sequentially extracting the balloon catheter 5, which is encased within its own structure, from multiple parallel thermoset spacers is taken into account. At the output end of the first electric push rod 9, the corresponding electric heating plate 7 and the first straight toothed plate 11 are automatically moved downward. At the same time, under the synchronous meshing transmission of the gear assembly 10, the second straight toothed plate 12 will move close to the first straight toothed plate 11. Thus, the two electric heating plates 7 move close to each other until multiple sets of two matching grooves 8 aligned vertically are fitted with the corresponding balloon tubes inside the balloon catheters 5. After completion, the two electric heating plates 7 are turned on to perform synchronous thermosetting treatment on the balloon tube structures inside the multiple balloon catheters 5. After a certain period of time, the first electric push rod 9 is turned off, and the output end of the first electric push rod 9 drives the corresponding electric heating plate 7 and the first straight toothed plate 11 to move upward and reset automatically. At the same time, under the synchronous meshing transmission of the gear assembly 10, the second straight toothed plate 12 drives another electric heating plate 7 to move away from the first straight toothed plate 11 and reset until the two electric heating plates 7 are in their initial positions. Then, the brake servo motor 15 is restarted, so that the conveyor belt 2 drives the two support shafts at the output end to drive the multiple thermosetting balloon catheters 5 to automatically move away from the thermosetting treatment cover 6. After the balloon catheter 5 is guided to the top area of ​​the arc-shaped top rod 195 in the middle after heat curing, the brake servo motor 15 is paused and the second electric push rod 194 is started. The output end of the second electric push rod 194 lifts the arc-shaped top rod 195 through the I-shaped shaft 192, the third spring 193 and the support plate 191 until the arc-shaped top rod 195 moves up inside the conveyor belt 2 and presses against the top structure of the conveyor belt 2. This causes the bottom of the multiple trapezoidal grooves 4 to be pressed, expanding its own top open structure, making it convenient for the user to remove the balloon catheter 5.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
