Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a carrier plate assembly and a puncture device having the carrier plate assembly. Background Technology

[0002] In the clinical application and storage of blood products, blood components collected by blood banks must undergo rigorous processing to meet safety standards. Because blood components carry a potential risk of viral contamination during collection and transportation, direct application or storage could lead to serious medical safety issues. Therefore, virus inactivation is a crucial step in the blood component preparation process. Currently, the mainstream virus inactivation methods in the industry include methylene blue photochemical inactivation, S-59 photochemical inactivation, and riboflavin photodynamic inactivation. Regardless of the method used, one of the core technical requirements is to achieve a connection between the finished blood product and the virus inactivation consumables. The quality of this connection directly determines the virus inactivation effect and the safety of the blood product, and is an important prerequisite for ensuring safe subsequent clinical use. To meet connectivity requirements and improve operational efficiency, blood banks commonly employ automated puncture devices in their existing technologies. These devices replace manual operation with standardized mechanical structures, reducing the risk of contamination and errors caused by human intervention. At the puncture device's workstation, a support plate assembly for securing blood bags is typically installed. The core functional component of this assembly is a clamp—generally composed of two connecting plates hinged at one end. One connecting plate is fixedly connected to the main body of the support plate, while the other can be opened around the hinge point. When securing the blood bag, the operator places the relevant tubing from the component blood bag into the groove on the inner side of the connecting plate, then closes the movable connecting plate. This allows the grooves of the two connecting plates to mate, forming a complete tubing accommodating channel, ultimately achieving relative stillness of the blood bag at the clamping station and providing a stable foundation for subsequent puncture operations. However, the existing clamping structure of the carrier plate assembly has obvious technical defects: its clamping and fixing method relies on manually tightening the connectors (such as bolts, clips, etc.) to fix the moving ends of the two connecting plates. This is not only cumbersome and time-consuming, reducing the overall operating efficiency of the device, but also prone to incomplete fixing due to uneven force applied by the operator or incomplete locking of the connectors. Once the clamping is not secure, when the turntable of the puncture device drives the carrier plate assembly and blood bag to the next station, the blood bag is very likely to detach from the original station and shift or fall. As the station continues to rotate, the shifted blood bag will collide and rub against the internal structure of the device cabinet, causing physical damage to the cabinet and directly preventing subsequent puncture, inactivation and other operations from being completed smoothly. In severe cases, it may even damage the environment of blood products, causing product scrapping and economic losses. Therefore, there is an urgent need for an easy-to-operate and reliable bearing plate assembly and a puncture device with such a bearing plate assembly to solve the problems of equipment damage and operation failure caused by the inconvenience of operation and inadequate fixation of the existing structure, and to ensure the stable operation of the puncture device and the safe handling of blood products. Utility Model Content

[0003] The purpose of this application is to provide a support plate assembly and a puncture device having the support plate assembly, so as to solve the problems of poor operation convenience and general clamping reliability of the support plate assembly in the prior art.

[0004] The embodiments of this application can be implemented through the following technical solutions: A support plate assembly includes a support plate and a detection component, wherein the detection port of the detection component is disposed facing the back of the support plate; The front side of the support plate is provided with a second clamping plate and a limiting member. Along the X-axis direction, one end of the second clamping plate is rotatably connected to the support plate, and the other end cooperates with the limiting member. The limiting member is provided with a limiting groove extending toward the second clamping plate at one end. The support plate is also provided with a triggering component that is connected through the Y direction. One end of the triggering component protrudes from the front of the support plate and corresponds to the free end of the second clamping plate. The triggering component has a reciprocating degree of freedom along the Y direction on the support plate. Under the action of force, the other end of the triggering component reciprocates along the Y direction inward and outward at the detection port.

[0005] Furthermore, the limiting member includes a base, a limiting strip, and a compression spring. One end of the limiting strip extends along the Y direction and is connected to one side of the base. The other end of the limiting strip has a wedge-shaped structure with a pointed end and a wide middle on the side facing the limiting groove. The other side of the base extends outward along the Y-axis to form a boss, and there is a gap along the X-axis between the boss and the limiting strip. The compression spring is disposed in the gap between the boss and the limiting strip.

[0006] Furthermore, the limiting member also includes an adjusting nut, one end of which passes through the boss along the X direction and is connected to one side of the fixed end of the limiting strip. The gap between the compression spring and the boss along the X axis is adjusted by the adjusting nut.

[0007] Furthermore, the support plate is provided with stepped holes, and the triggering component includes a trigger pin and a spring. The trigger pin has an annular limiting protrusion in the middle, and the spring is sleeved on the outside of the trigger pin, with its two ends respectively abutting against the side of the limiting protrusion facing the detection component and the inner wall step surface of the stepped hole.

[0008] Furthermore, the bearing plate includes a plate body and a first clamping plate fixedly connected to the front side of the plate body along the X direction. One end of the first clamping plate is hinged to the second clamping plate, together forming a clamp. The other end of the first clamping plate is provided with a first stepped hole that runs through the Y direction. The bearing plate is provided with a second connecting hole that mates with the first stepped hole. The first stepped hole and the second connecting hole mate to form a stepped hole. A connecting plate is detachably fixed to the back of the plate. A limiting through hole that mates with the second connecting hole is provided in the middle of the connecting plate. The diameter of the limiting through hole of the connecting plate is smaller than the diameter of the second connecting hole, together forming a limiting structure with small diameters at both ends and large diameters in the middle.

[0009] Furthermore, the first clamping plate and the second clamping plate are respectively provided with a plurality of receiving grooves that pass through along the Z-axis direction; when the other end of the second clamping plate is tightly fitted with the first clamping plate through the limiting member, the plurality of corresponding receiving grooves together form the clamping hole of the fixture.

[0010] Furthermore, the support plate also includes a storage box, which is disposed below the clamp. The top of the storage box is open, and the sides of the storage box gradually taper from the top opening to the bottom.

[0011] Furthermore, the storage box is detachably connected to the plate.

[0012] This application also provides a puncture device, including the support plate assembly as described above, and further including a turntable and a fixed worktable. The support plate is connected to the side of the turntable along the circumference of the turntable. The detection component is fixedly connected to the fixed worktable. The turntable and the fixed worktable are arranged vertically or coaxially along the Z-axis. The central axis of the turntable is connected to the output end of the drive device. Under the driving action of the drive device, the turntable drives the support plate to rotate relative to the fixed worktable.

[0013] Furthermore, a light-shielding plate is provided at the end of the trigger pin of the triggering component facing the detection port, and the detection component is a photoelectric sensor; The detection component is connected to the drive device of the turntable through a control system.

[0014] The embodiments of this application provide a carrier plate assembly and a puncture device having the carrier plate assembly, which have at least the following beneficial effects: This application, by setting a rotatable second clamping plate and a limiting component with a limiting slot on the front of the support plate, can form a stable clamping and precise limiting of the workpiece placed on the front of the support plate along the X-axis direction, effectively preventing displacement of the workpiece during subsequent operation or testing, and ensuring the stability of operation and testing. At the same time, a trigger component with a reciprocating displacement degree is connected through the support plate along the Y-direction. One end of the trigger component corresponds to the free end of the second clamping plate, and the other end can reciprocate inside and outside the detection port of the detection component under the action of force, realizing the linkage between the clamping state of the workpiece and the detection action. This not only simplifies the operation process, but also allows the detection to be triggered without additional complicated operations, improving detection efficiency. Furthermore, the precise displacement of the trigger component ensures that the detection component only performs detection when the workpiece is in a stable clamping state, reducing false detections and ensuring detection accuracy. It has the advantages of simple overall structure, flexible cooperation of each component, adaptability to the clamping and detection needs of different specifications of workpieces, and enhanced versatility and practicality of the component.

Detailed Implementation

[0017] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0018] Furthermore, for ease of understanding, various components on the drawings have been enlarged or reduced, but this is not intended to limit the scope of protection of this application.

[0019] Singular forms of words also include plural meanings, and vice versa.

[0020] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use, they are only for the convenience of describing this application and 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, and therefore should not be construed as a limitation on this application. In addition, in the description of this application, in order to distinguish different units, the terms "first," "second," etc. are used in this specification, but these are not limited by the manufacturing order, nor should they be construed as indicating or implying relative importance. Their names may differ in the detailed description and claims of this application.

[0021] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. It should also be noted that, unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.

[0022] For ease of description, using Figure 2 The extension direction of the clamp 22 is the X-axis direction; in the same horizontal plane, the direction perpendicular to the X-axis is the Y-axis direction; the length direction of the bearing plate 2 is the Z-axis direction, and the Z-axis is perpendicular to the XY plane formed by the X-axis and the Y-axis.

[0023] like Figure 1 , Figure 2As shown, a support plate assembly includes a support plate 2 fixedly connected to the side of a turntable 1 along its circumference and a detection component 4 disposed on a fixed worktable 3. The turntable 1 and the fixed worktable 3 are arranged vertically or coaxially along the Z-axis. The support plate 2 and the detection component 4 form a spatial fit relationship. The detection port of the detection component 4 faces the back of the support plate 2. The front of the support plate 2 is provided with a second clamping plate 222 and a limiting member 23. Along the X-axis, one end of the second clamping plate 222 is rotatably connected to the support plate 2. On the carrier plate 2, the other end cooperates with the limiting member 23. The limiting member 23 has a limiting groove 230 extending toward the second clamping plate 222 at one end. When the second clamping plate 222 is rotated, the free end of the second clamping plate 222 first abuts against the surface of the limiting member 23, and then slides along the surface of the limiting member 23 into the limiting groove 230. Through the limiting effect of the groove wall of the limiting groove 230, the second clamping plate 222 is firmly locked to the front of the carrier plate 2, realizing the stable closure of the second clamping plate 222.

[0024] In some preferred embodiments, such as Figure 3 As shown, the limiting member 23 includes a base 231, a limiting strip 232, and a compression spring 233. One end of the limiting strip 232 extends along the Y direction and is connected to one side of the base 231. The other end of the limiting strip 232 faces the limiting slot 230 and has a wedge-shaped structure with a pointed end and a wide middle, which is used to guide the sliding trajectory of the second clamping plate 222 through the wedge-shaped structure.

[0025] In some preferred embodiments, the base 231 extends outward along the Y-axis on the side opposite to the limiting strip 232 to form a boss 2310. An adjustment gap is reserved between the boss 2310 and the limiting strip 232 along the X-axis. The compression spring 233 is disposed along the X-axis in the adjustment gap between the boss 2310 and the limiting strip 232 to enable the limiting strip 232 to adaptively abut against the side wall of the limiting strip 232. This ensures that during clamping, the second clamping plate 222 can be smoothly pushed into the limiting slot 230, and the limiting strip 232 is tightly pressed against the end of the second clamping plate 222 under the elastic action of the compression spring 233, thus ensuring the reliability of clamping.

[0026] The limiting member 23 also includes an adjusting nut 234. One end of the adjusting nut 234 passes through the boss 2310 along the X direction and is connected to one side of the fixed end of the limiting strip 232. The gap between the compression spring 233 and the boss 2310 and the limiting strip 232 along the X axis is adjusted by the adjusting nut 234 to precisely control the pre-compression amount of the compression spring 233, thereby adapting to different clamping requirements.

[0027] Furthermore, to achieve the detection linkage of the clamping state, the support plate 2 is also provided with a trigger component 5 that is connected through along the Y direction. One end of the trigger component 5 protrudes from the front of the support plate 2 and cooperates with the free end of the second clamping plate 222, and has a reciprocating degree of freedom along the Y direction on the support plate 2. Under the action of force, the other end of the trigger component 5 reciprocates along the Y direction inside and outside the detection port. When the second clamping plate 222 is closed and inserted into the limiting groove 230, the second clamping plate 222 can be pushed... The triggering component 5 moves along the Y-axis to the back of the support plate 2 until the end of the triggering component 5 extends into the detection port. When the second clamping plate 222 is opened and the second clamping plate 222 moves out of the limiting slot 230, the end of the triggering component 5 exposed on the front of the support plate 2 can be pulled to move along the Y-axis to the front of the support plate 2, or an elastic component can be sleeved on the outside of the triggering component 5 to automatically push the end of the triggering component 5 out of the detection port and restore it to its initial position using the restoring force of the elastic component.

[0028] In some preferred embodiments, such as Figure 4 , Figure 5 As shown, the support plate 2 is provided with a stepped hole 20, and the triggering component 5 includes a trigger pin 51 and a spring 52; the trigger pin 51 is provided with an annular limiting protrusion 511 in the middle, and the spring 52 is sleeved on the outside of the trigger pin 51, with its two ends respectively abutting against the side of the limiting protrusion 511 facing the detection component 4 and the inner wall step surface of the stepped hole 20, forming an elastic constraint; when the second clamping plate 222 squeezes the trigger pin 51 to move towards the detection component 4, the spring 52 is compressed and stores energy; when the second clamping plate 222 releases the squeeze, the spring 52 releases its elastic force to push the limiting protrusion 511 to drive the trigger pin 51 to reset, so that the end of the trigger pin 51 away from the detection component 4 automatically exits the detection port.

[0029] In some preferred embodiments, to increase the travel of the trigger component along the Y direction on the support plate 2, provide sufficient reset space for the spring 52, and enhance the convenience of processing and assembly, the stepped hole 20 adopts a split design. The support plate 2 includes a plate body 21 and a first clamping plate 221 fixedly connected to the front of the plate body 21 along the X direction. One end of the first clamping plate 221 has a first stepped hole 2210 extending along the Y direction. The support plate 2 has a second connecting hole 210 that mates with the first stepped hole 2210. Hole 210 is a through hole. The first stepped hole 2210 and the second connecting hole 210 cooperate to form a stepped hole. A connecting plate 54 is detachably fixed to the back of the plate 21. A limiting through hole 540 that cooperates with the second connecting hole 210 is opened in the middle of the connecting plate 54. The diameter of the limiting through hole 540 of the connecting plate 54 is smaller than the diameter of the second connecting hole 210, so that the hole that limits the displacement of the trigger pin 51 presents a limiting structure with small diameters at both ends and large diameters in the middle, thereby limiting the displacement stroke of the trigger pin 51 along the Y-axis.

[0030] In some preferred embodiments, a light-shielding plate 53 is provided at the end of the trigger pin 51 facing the detection port. The detection component 4 is a photoelectric sensor, which includes a light-emitting end and a light-receiving end arranged opposite each other, forming a detection optical path. The detection port is a gap area through which the optical path passes. The light-shielding plate 53 moves back and forth within the detection port: when the second clamping plate 222 closes into the limiting slot 230 and pushes the trigger pin 51 to move, the light-shielding plate 53 extends into the detection port along with the trigger pin 51, and the detection optical path of the detection component 4 causes the sensor to output a clamping signal; when the second clamping plate 222 opens and the trigger pin 51 resets, the light-shielding plate 53 exits the detection port along with the trigger pin 51, the detection optical path resumes conduction, and the sensor outputs a clamping signal.

[0031] In some preferred embodiments, the detection component 4 and the drive device of the turntable 1 are connected through a control system to achieve signal connection and linkage control. When the detection component 4 sends a signal that the clamping is in place, the drive device of the turntable 1 drives the turntable 1 to rotate, so that the support plate 2 rotates to the next station. When the detection component 4 sends a signal that the clamping is not in place, the drive device of the turntable 1 remains in a stopped state, and the turntable 1 and the support plate 2 remain stationary at the current station.

[0032] In some preferred embodiments, the other end of the first clamping plate 221 and one end of the second clamping plate 222 are hinged together to form a clamp 22. The first clamping plate 221 and the second clamping plate 222 are respectively provided with a plurality of receiving grooves that pass through the Z-axis direction. When the other end of the second clamping plate 222 is tightly fitted with the first clamping plate 221 through the limiting member 23, the plurality of corresponding receiving grooves are together to form a clamping hole for accommodating the pipeline and positioning it.

[0033] In some preferred embodiments, the carrier plate 2 further includes a needle handle positioning part 25, which is connected to the middle part of the carrier plate 2 and disposed below the clamp 22. The needle handle positioning part 25 has a groove that is adapted to the needle handle of the puncture needle, which is used to transfer the needle handle of the puncture needle on the consumable bag, so that the puncture needle for transferring the consumable bag can be accurately inserted into the transfusion port with diaphragm of the component blood bag, thereby connecting the two and transferring blood.

[0034] In some preferred embodiments, the support plate 2 further includes a storage box 24, which is disposed below the needle handle positioning part 25. The top of the storage box 24 is open, and the sides of the storage box 24 gradually taper from the top opening to the bottom, so that the cross-sectional dimensions of the box gradually decrease along the height direction (Z-axis direction). This allows for lateral restraint of accessories placed in the storage box 24, preventing them from falling out of the box due to shaking during the rotation of the support plate 2 with the turntable 1. At the same time, it allows the items to naturally gather at the bottom for easy retrieval laterally.

[0035] The storage box 24 is detachably connected to the plate 21. The storage box 24 and the plate 21 are detachably connected by mutually cooperating permanent magnets and iron sheets or mutually cooperating bolts and threaded holes. This facilitates the quick assembly and disassembly of the storage box 24, making it easy to clean, disinfect or replace it separately. It also allows for flexible adjustment of the installation position or specifications of the storage box 24 according to actual usage needs, improving the flexibility of use and the convenience of maintenance of the support plate assembly.

[0036] In some preferred embodiments, this application also provides a puncture device, including the support plate assembly as described above, a turntable 1 and a fixed worktable 3, wherein the support plate 2 is connected to the side of the turntable 1 along the circumference of the turntable 1, the detection component 4 is fixedly connected to the fixed worktable 3, the turntable 1 and the fixed worktable 3 are arranged vertically or coaxially along the Z-axis, the central axis of the turntable 1 is connected to the output end of the drive device, and under the driving action of the drive device, the turntable 1 drives the support plate 2 to rotate relative to the fixed worktable 3.

[0037] In some preferred embodiments, the puncture device further includes a cabinet with a fresh air system (not shown in the figure) connected to its top. This fresh air system draws in outside air into its internal plasma electric field for disinfection and then exhausts the disinfected air into the cabinet, followed by discharge through the cabinet's air outlet. This creates a positive-pressure purification chamber within the cabinet. Along the rotation direction of the turntable 1, the purification chamber also includes a cap removal mechanism, a transfusion port cutting mechanism, a needle puncture mechanism, and a welding sealing mechanism, all facing the outer surface of the turntable 1. Specific structural details are not further elaborated here.

[0038] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
