Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a catheter recovery device and a double-station automatic winding device. Background Art

[0002] Infusion sets are common medical consumables used for infusion therapy, such as colds and fevers. These sterile, disposable medical devices are primarily used for intravenous infusions, establishing a pathway between the vein and the medication. They are typically packaged after being coiled.

[0003] In the prior art, a winding device is used to wind the infusion pump. The winding device includes a lifting frame slidably connected to a bracket in a vertical direction. A lifting drive source capable of driving the lifting frame to move vertically relative to the bracket is provided between the lifting frame and the bracket. A winding manipulator arranged in a vertical direction is connected to the side of the lifting frame. The lower end of the winding manipulator can clamp one end of the infusion pump and can wind the infusion pump around the outer surface of the lower end of the winding manipulator by rotating the infusion pump. This winding device has poor clamping stability for the infusion pump, low efficiency, and occupies a large space. Utility Model Content

[0004] The purpose of the utility model is to provide a catheter recovery device and a double-station automatic winding device to alleviate the technical problems of low production efficiency, poor clamping stability and large space occupation of the infusion set winding device in the prior art.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] In the first aspect, the catheter recovery device provided by the present invention includes a transmission mechanism, a rotating mechanism and two catheter winding mechanisms; the transmission mechanism includes a first driving member, a fixed component and a connecting component located on the periphery of the fixed component and slidingly connected to the fixed component, the first driving member is transmission-connected to the connecting component to drive the connecting component to rise and fall relative to the fixed component; the two catheter winding mechanisms are respectively connected to two opposite side walls of the connecting component, the first driving member and the rotating mechanism are respectively connected to the other two opposite side walls of the connecting component; the rotating mechanism is transmission-connected to the two catheter winding mechanisms, driving the two catheter winding mechanisms to rotate around their own axis so that the upper end of the catheter winding mechanism winds around the infusion pump.

[0007] Because the catheter recovery device includes two catheter winding mechanisms, it is possible to wind two infusion pumps at the same time, thereby improving work efficiency. Because the rotating mechanism and the two catheter winding mechanisms are both connected to the connecting assembly, when the first driving member drives the connecting assembly to rise and fall, the rotating mechanism and the two catheter winding mechanisms are synchronously lifted and lowered, thereby avoiding the problem of the rotating mechanism and the two catheter winding mechanisms being individually matched with the lifting driving member and occupying a large amount of space. Because the two catheter winding mechanisms are arranged relative to each other, and the first driving member and the rotating mechanism are arranged relative to each other, the catheter recovery device is centrally symmetrical as a whole, making the overall structure compact and further reducing the volume of the catheter recovery device. Because the upper end of the catheter winding mechanism is wound around the infusion pump, the catheter winding mechanism can both wind the infusion pump and support the infusion pump, thereby reducing the clamping force required by the clamping claws of the catheter winding mechanism to clamp the infusion pump and enhancing the clamping stability.

[0008] Furthermore, the fixing assembly includes two slide rail plates that are arranged opposite to each other, and the connecting assembly includes two sliding plates. The two sliding plates are respectively slidably matched with the two slide rail plates and are respectively equipped with the catheter winding mechanism.

[0009] The slide rail plate and the sliding plate are slidably matched to realize the slidable match between the connecting component and the fixed component.

[0010] Furthermore, the connecting assembly also includes two connecting plates arranged opposite to each other, both ends of the connecting plates are respectively connected to the two sliding plates and are perpendicular to the two sliding plates; the two connecting plates are respectively installed with the first driving member and the rotating mechanism.

[0011] The connecting plate provides support for the first driving member or the rotating mechanism; and because the connecting plate is connected to the sliding plate, the sliding plate drives the connecting plate to rise and fall simultaneously, thereby achieving the effect that the first driving member drives the rotating mechanism and the two catheter winding mechanisms simultaneously, reducing the number of driving members and thus reducing the volume of the catheter recovery device.

[0012] Furthermore, both ends of the connecting plate on which the rotating mechanism is installed are provided with avoidance grooves.

[0013] The avoidance groove prevents the connection plate from affecting the connection between the rotating mechanism and the catheter winding mechanism.

[0014] Furthermore, the fixing assembly further includes a fixing plate, and two sides of the fixing plate are respectively connected to the two slide rail plates.

[0015] The fixing plate connects the two slide rail plates and improves the strength of the fixing assembly.

[0016] Furthermore, the catheter winding mechanism includes a fixed jaw and two oppositely arranged winding jaws, the fixed jaw is located between the two winding jaws; the rotating mechanism is transmission-connected to the two winding jaws to drive the two winding jaws to rotate around the axis of the catheter winding mechanism.

[0017] The fixing clamping jaw fixes the end of the infusion set, and the winding clamping jaw winds the infusion set around its periphery. The two clamping jaws work together to realize the winding of the infusion set.

[0018] Furthermore, the catheter winding mechanism further includes a second driving member, which is transmission-connected to at least one of the winding jaws to drive the two winding jaws to move toward or away from each other.

[0019] The two winding jaws can move toward or away from each other, so that the winding diameter of the infusion set can be controlled before or during the winding process to adapt to infusion sets of different sizes.

[0020] Furthermore, the catheter winding mechanism includes a protective sleeve, a third driving member and an intermediate shaft; the fixed clamp is fixed to the top of the protective sleeve, the intermediate shaft passes through the protective sleeve and one end is transmission-connected to the two winding clamps, and the other end is transmission-connected to the rotating mechanism; the third driving member is connected to the fixed clamp to drive the fixed clamp to open and close.

[0021] The intermediate shaft passes through the protective sleeve and its two ends are respectively connected to the rotating mechanism and the two winding jaws. The fixed jaws are fixed to the protective sleeve to ensure that the fixed jaws are stationary, and the rotating mechanism can drive the two winding jaws to perform winding motion.

[0022] Furthermore, the rotating mechanism includes a fourth driving member, a transmission belt and a mounting plate; the mounting plate is connected to the connecting assembly, the fourth driving member is installed on the mounting plate and connected to the transmission belt; the transmission belt is simultaneously connected to the two intermediate shafts of the two catheter winding mechanisms.

[0023] The fourth driving member is connected to the two catheter winding mechanisms via a transmission belt, so that one driving member can simultaneously drive the two catheter winding mechanisms to rotate around their own axes, thereby reducing the number of driving members and thus reducing the volume of the catheter recovery device.

[0024] In a second aspect, the double-station automatic winding equipment provided by the present invention includes a protective plate and at least two catheter recovery devices as described in any one of the above items; the protective plate is provided with a through hole, the catheter winding mechanism in the catheter recovery device extends out of the through hole, and the fixing component in the catheter recovery device is connected to the protective plate.

[0025] The protective plate serves as the frame of the dual-station automatic winding equipment, providing both protection and fixation. Two catheter recovery devices are provided, enabling dual-station operation and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0047] Example 1

[0048] The catheter recovery device provided by the embodiment of the present invention includes a transmission mechanism 100, a rotating mechanism 200 and two catheter winding mechanisms 300; the transmission mechanism 100 includes a first driving member 110, a fixing assembly 120 and a connecting assembly 130 located on the periphery of the fixing assembly 120 and slidingly connected to the fixing assembly 120, the first driving member 110 is transmission-connected to the connecting assembly 130 to drive the connecting assembly 130 to rise and fall relative to the fixing assembly 120; the two catheter winding mechanisms 300 are respectively connected to two opposite side walls of the connecting assembly 130, the first driving member 110 and the rotating mechanism 200 are respectively connected to the other two opposite side walls of the connecting assembly 130; the rotating mechanism 200 is transmission-connected to the two catheter winding mechanisms 300, driving the two catheter winding mechanisms 300 to rotate around their own axis so that the upper end of the catheter winding mechanism 300 is wound around the infusion pump.

[0049] Specifically, see Figures 1 to 5 , the connecting component 130 is square in shape as a whole and is located on the periphery of the fixed component 120; the two catheter winding mechanisms 300, the first driving member 110 and the rotating mechanism 200 are respectively connected to the four side walls of the connecting component 130. The fixed component 120 is used to connect to the frame, for example, the fixed component 120 is connected to the bottom surface of the protective plate 400, so that the fixed component 120 is fixed and provides support for other parts. In this embodiment, the first driving member 110 is configured as a cylinder, and the cylinder body and the piston rod are respectively connected to the connecting component 130 and the fixed component 120, so that when the piston rod extends or retracts the cylinder body, the connecting component 130 is driven to rise and fall relative to the fixed component 120. Of course, the first driving member 110 is configured as other linear driving members, such as electric push rods, etc., which should also be within the protection scope of the embodiments of the present utility model.

[0050] Because the catheter recovery device includes two catheter winding mechanisms 300, it can simultaneously wind two infusion pumps, improving work efficiency. Because the upper end of the catheter winding mechanism 300 is wound around the infusion pump, the catheter winding mechanism 300 can both wind the infusion pump and provide support for the infusion pump, reducing the clamping force required by the clamping claws of the catheter winding mechanism 300 to clamp the infusion pump and enhancing clamping stability. Because the rotating mechanism 200 and the two catheter winding mechanisms 300 are both connected to the connecting assembly 130, when the first driving member 110 drives the connecting assembly 130 to rise and fall, the rotating mechanism 200 and the two catheter winding mechanisms 300 are synchronously raised and lowered, avoiding the problem of the rotating mechanism 200 and the two catheter winding mechanisms 300 being separately equipped with lifting and lowering driving components and occupying a large amount of space. Because the two catheter winding mechanisms 300 are arranged relative to each other and the first driving member 110 and the rotating mechanism 200 are arranged relative to each other, the catheter recovery device is centrally symmetrical as a whole, making the overall structure compact and further reducing the volume of the catheter recovery device.

[0051] The structure and shape of the transmission mechanism 100 are described in detail below:

[0052] In the optional solutions of the embodiment of this utility model, please see Figure 2 The fixing assembly 120 includes two slide rail plates 121 arranged opposite to each other, and the connecting assembly 130 includes two sliding plates 131. The two sliding plates 131 are respectively slidably matched with the two slide rail plates 121 and are respectively equipped with a catheter winding mechanism 300.

[0053] Specifically, the outer surface of the slide plate 121 is provided with a slide rail, which extends in the vertical direction; a slider is slidably installed in the slide rail, and the slide plate 131 is connected to the slider to achieve sliding cooperation between the slide plate 121 and the slide plate 131. Preferably, two slide rails are provided, and the two slide rails are spaced apart to achieve stable movement of the slide plate 131. For further information, please refer to Figure 2 The catheter winding mechanism 300 is connected to the sliding plate 131 by screws, which facilitates the installation and disassembly of the catheter winding mechanism 300.

[0054] The slide rail plate 121 and the sliding plate 131 are slidably matched to achieve the slidable match between the connecting component 130 and the fixing component 120 .

[0055] In the optional solutions of the embodiment of this utility model, please see Figure 3 The connecting assembly 130 also includes two oppositely arranged connecting plates 132, both ends of the connecting plates 132 are respectively connected to the two sliding plates 131 and are perpendicular to the two sliding plates 131; the two connecting plates 132 are respectively installed with the first driving member 110 and the rotating mechanism 200.

[0056] Specifically, the two connecting plates 132 and the two sliding plates 131 enclose a cavity, and the fixing assembly 120 is located in the cavity. Preferably, the two ends of the connecting plate 132 are connected to the two sliding plates 131 by screws, which is a simple connection method and easy to install and remove. For further information, please refer to Figure 4 A bottom plate 133 is fixed under the two connecting plates 132 to improve the stability of the connecting assembly 130.

[0057] The connecting plate 132 supports the first driving member 110 or the rotating mechanism 200; and because the connecting plate 132 is connected to the sliding plate 131, the sliding plate 131 drives the connecting plate 132 to rise and fall at the same time, thereby achieving the effect of the first driving member 110 driving the rotating mechanism 200 and the two catheter winding mechanisms 300 at the same time, reducing the number of driving members and thus reducing the volume of the catheter recovery device.

[0058] In the optional solutions of the embodiment of this utility model, please see Figure 3 Both ends of the connecting plate 132 on which the rotating mechanism 200 is installed are provided with avoidance grooves 1321.

[0059] Specifically, the bottoms of both end surfaces of the connecting plate 132, on which the rotating mechanism 200 is mounted, are recessed inward to form escape grooves 1321, which prevent the rotating mechanism 200 from rotating. More specifically, the rotating mechanism 200 includes a conveyor belt, which passes through the escape grooves 1321 and connects to the catheter winding mechanism 300. Furthermore, the escape grooves 1321 are provided on both connecting plates 132, ensuring a consistent structure for both connecting plates 132, ensuring the stability of the connecting assembly 130, and reducing the weight and cost of the connecting assembly 130.

[0060] The connection plate 132 on which the rotating mechanism 200 is installed is provided with an avoidance groove 1321 to prevent the connection plate 132 from affecting the connection between the rotating mechanism 200 and the catheter winding mechanism 300.

[0061] In an optional solution of the embodiment of the present invention, the fixing assembly 120 further includes a fixing plate 122 , and two sides of the fixing plate 122 are respectively connected to the two slide rail plates 121 .

[0062] Specifically, the fixing plate 122 is located between the two slide rail plates 121 and is perpendicular to the slide rail plates 121. Figure 2 The piston rod of the first driving member 110 is installed on the top of the fixed plate 122 through the adapter plate 123, and the cylinder body of the first driving member 110 is installed on the connecting plate 132.

[0063] The fixing plate 122 connects the two slide rail plates 121 to improve the strength of the fixing assembly 120 .

[0064] The principle of the transmission mechanism 100 is described in detail below:

[0065] The transmission mechanism 100 is configured as an inner and outer ring structure, with the fixed component 120 located inside as the inner ring, and the inner ring serving as a stationary part; the connecting component 130 is located outside as the outer ring, and the outer ring serves as a structure that moves up and down and fixes the first driving member 110, two catheter winding mechanisms 300 and the rotating mechanism 200 respectively, and the inner and outer rings provide a liftable structure; the two catheter winding mechanisms 300 are installed on both sides of the outer ring, and the first driving member 110 and the rotating mechanism 200 are installed on the other two sides of the outer ring. The layout of the inner and outer rings is cleverly utilized to install all the structures together, which ensures that the spatial structure is small and also presents central symmetry to ensure the convenience of disassembly and assembly and the ornamental effect of the structure.

[0066] The structure and shape of the catheter winding mechanism 300 are described in detail below:

[0067] In an optional solution of an embodiment of the present invention, the catheter winding mechanism 300 includes a fixed jaw 310 and two oppositely arranged winding jaws 320, and the fixed jaw 310 is located between the two winding jaws 320; the rotating mechanism 200 is transmission-connected to the two winding jaws 320 to drive the two winding jaws 320 to rotate around the axis of the catheter winding mechanism 300.

[0068] Specifically, the fixed clamp 310 is used to clamp the end of the infusion pump, and the rotating mechanism 200 drives the two winding clamps 320 to rotate around the axis of the catheter winding mechanism 300 to wind the infusion pump around the outer periphery of the two winding clamps 320, thereby winding the infusion pump.

[0069] The fixing jaw 310 plays a fixing role, and the winding jaw 320 plays a winding role.

[0070] In an optional solution of the embodiment of the present invention, the catheter winding mechanism 300 further includes a second driving member, which is transmission-connected to at least one winding jaw 320 to drive the two winding jaws 320 to move toward or away from each other.

[0071] Specifically, see Figure 4 A spring 350 is installed between the two winding jaws 320 to ensure that the two winding jaws 320 are in a normally closed state when the winding jaws 320 are not driven. The second driving member is a cylinder. Preferably, see Figure 2 The winding clamp 320 includes a finger fixing block 321 and a tube winding finger 322 , one end of the finger fixing block 321 is connected to the second driving member, and the other end is connected to the tube winding finger 322 .

[0072] The two winding jaws 320 can move toward or away from each other, so that the winding diameter of the infusion pump can be controlled before or during the winding process to adapt to infusion pumps of different sizes.

[0073] In an optional scheme of an embodiment of the present invention, the catheter winding mechanism 300 includes a protective sleeve 330, a third driving member 340 and an intermediate shaft; the fixed clamp 310 is installed on the top of the protective sleeve 330, the intermediate shaft passes through the protective sleeve 330 and one end is transmission-connected to the two winding clamps 320, and the other end is transmission-connected to the rotating mechanism 200; the third driving member 340 is connected to the fixed clamp 310 to drive the fixed clamp 310 to open and close.

[0074] Specifically, the catheter winding mechanism 300 further includes a fixing base 360, which is located below the protective sleeve 330 and connected to the sliding plate 131. The intermediate shaft sequentially passes through the fixing base 360 ​​and the protective sleeve 330. The third driving member 340 is configured as a cylinder and is located above the second driving member, which is mounted within the protective sleeve 330, fully utilizing the space within the protective sleeve 330.

[0075] The cylinder is connected to the fixed jaw 310, driving it to open and close, thereby tightening or loosening the end of the infusion set. The fixed jaw 310 is mounted on top of the protective sleeve 330. The intermediate shaft passes through the protective sleeve 330 and is in transmission connection with the winding jaw 320, ensuring that the fixed jaw 310 remains stationary and does not rotate. The hollow protective sleeve 330 and the fixed base 360 ​​create an overall shape similar to the central axis of symmetry for the catheter winding mechanism 300, ensuring both structural functionality and enhancing the overall compactness and aesthetics.

[0076] The shape and structure of the rotating mechanism 200 are described in detail below:

[0077] In an optional solution of an embodiment of the present invention, the rotating mechanism 200 includes a fourth driving member 210, a transmission belt 220 and a mounting plate 230; the mounting plate 230 is connected to the connecting assembly 130, the fourth driving member 210 is installed on the mounting plate 230, and is connected to the transmission belt 220; the transmission belt 220 is simultaneously connected to the two intermediate shafts of the two catheter winding mechanisms 300.

[0078] Specifically, see Figure 1The fourth driving member 210 is configured as a motor, mounted on a mounting plate 230, which is vertically connected to the connecting plate 132 via bolts or screws. Preferably, the motor is mounted below the mounting plate 230. A transmission belt 220 is connected to the motor's output shaft via a first synchronous pulley, and the transmission belt 220 is connected to the intermediate shafts of the two conduit winding mechanisms 300 via a second synchronous pulley. The motor drives the transmission belt 220 to rotate, which in turn drives the two intermediate shafts of the two conduit winding mechanisms 300 to rotate.

[0079] The motor is connected to the two catheter winding mechanisms 300 via the transmission belt 220 , so that one motor can simultaneously drive the two catheter winding mechanisms 300 to rotate around their own axes, thereby reducing the number of driving components and thus reducing the volume of the catheter recovery device.

[0081] The double-station automatic winding device provided in the embodiment of the present invention includes the catheter recovery device described in the first embodiment, and therefore also has all the beneficial effects of the first embodiment, which will not be described in detail here.

The protective plate 400 is provided with a through hole 410. The catheter winding mechanism 300 in the catheter recovery device extends out of the through hole 410.
