Description
Technical Field
[0001] This invention relates to the field of medical equipment technology, and in particular to a clamping device for multiple sets of infusion bags. Background Technology
[0002] Currently, medication preparation in vials is done manually. Typically, a syringe is used to draw the medication from the infusion bag, the needle is inserted into the vial to inject the medication, and the person holding the vial shakes it to mix the medication. Then, the needle is inserted again, the vial is inverted, and the medication is drawn out. The syringe is then used to inject the remaining medication into the infusion bag, and the syringe is removed, completing the transfer of the medication. This method is cumbersome, inefficient, time-consuming, and carries the risk of medication errors, especially in high-volume preparations where the workload is high. Therefore, automated medication preparation systems are needed to improve efficiency and prevent errors. However, existing automated techniques typically use clamps to hold the infusion bags, which cannot handle batch loading, clamping, and unloading of different sizes of infusion bags. Furthermore, the clamped infusion bags have poor stability, making the process complex. Summary of the Invention

[0010] Preferably, the drive assembly includes a push rod connected to the second guide slide assembly. One end of the push rod is connected to the inner wall of the mounting base housing via a push rod spring.

[0017] The beneficial effects of this invention are:
[0018] 1. By pressing down on the arc-shaped opening of the infusion bag, the bag opening is fully fitted with the multi-position slot. This allows the clamping blocks on both sides to adaptively clamp the bag opening under the force of the torsion spring. The bag body is then clamped onto the clamping frame, thus completing the bag loading and clamping operation. By using a multi-position slot that matches the opening of different models of infusion bags, the bag loading and clamping operation of different models of infusion bags can be achieved, thereby improving the bag loading speed and the flexibility of the device.
[0019] 2. By pushing the handle along the guide groove to the push rod side, the roller pushes the infusion bag clamping block to move, thereby quickly opening the infusion bag clamping block and increasing the speed of infusion bag unloading. By rotating the handle, the locking block is locked in the locking cavity. Under the elastic force of the locking block spring, the locking block is pressed tightly against the vertical side wall of the locking cavity, thereby preventing the locking block from falling out of the locking cavity and improving the reliability of the device.
[0020] 3. By rotating the handle in the opposite direction, the locking block is released from the locking cavity. The locking block spring acts as a buffer against the instantaneous release force of the push rod spring, thereby reducing the impact force generated by the instantaneous release of the push rod spring and improving the stability of the device.
[0021] 4. When the locking block is released from the locking cavity, the push rod pushes the handle under the elastic force of the push rod spring, thereby causing the push rod and handle to quickly reset, so that the roller two moves away from the infusion bag clamping block, and the infusion bag clamping block resets under the elastic force of the torsion spring, thereby causing the entire device to quickly reset, thus improving the efficiency of loading and unloading infusion bags, and the operation is simple.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Please see Figure 1-2 This invention provides a multi-set infusion bag clamping device, including a mounting base 11. A guide slide assembly 12 is provided on one side of the mounting base 11. Several sets of clamping assemblies 13 for clamping the mouth of the infusion bag are linearly arrayed along the distribution direction of the guide slide assembly 12. A motion cavity 14 is provided in the middle of the mounting base 11. A guide slide assembly 15 is provided on the side wall of the motion cavity 14. The guide slide assembly 15 is provided with a drive assembly 16 for controlling the clamping or releasing of the clamping assembly 13. The drive assembly 16 is provided with a roller 17 for pushing the clamping assembly 13. A mounting base housing 18 is provided on the top of the mounting base 11. The mounting base housing 18 is provided with a clamping frame 19 for clamping the infusion bag corresponding to the clamping assembly 13.
[0036] Specifically, the first guide slide assembly 12 is disposed on one side of the long side of the mounting base 11, and the second guide slide assembly 15 is disposed on one side of the long side of the motion cavity 14.
[0037] Specifically, the first guide slide assembly 12 includes a guide rail 121 provided on one side of the long side of the mounting base 11, and the guide rail 121 is movably provided with a plurality of sliders 122 connected to the clamping assembly 13. The second guide slide assembly 15 includes a guide rail 151 provided on one side of the motion cavity 14, and the guide rail 151 is movably provided with a plurality of sliders 152 connected to the driving assembly 16.
[0038] like Figure 10 and 11 As shown, specifically, the clamping assembly 13 includes a mounting block 131 on the top of the mounting base 11. Symmetrically arranged on the top of the mounting base 11 about the mounting block 131 are infusion bag clamping blocks 132 connected to the guide sliding assembly 12. A waist-shaped groove 1321 is provided in the middle of the infusion bag clamping block 132. A roller 133 is movably arranged within the waist-shaped groove 1321. Both sides of the rollers 133 are connected to a transmission rod 134. A through hole 1341 is provided in the middle of the transmission rod 134. A mounting block bolt 135 is provided through the through hole 1341 and connected to the mounting block 131. A baffle 136 is provided at the end of the mounting block bolt 135 away from the mounting block 131. A torsion spring 137, which drives the transmission rod 134 to swing, is sleeved between the mounting block bolt 135, the baffle 136, and the transmission rod 134. A washer 138 for mounting the transmission rod 134 is provided at the center of the bottom of the transmission rod 134.
[0039] Specifically, the infusion bag clamp 132 has an arc-shaped opening 1322 on the side near the clamping frame 19. The arc-shaped opening 1322 contains a multi-position slot 1323 that matches the openings of different types of infusion bags. By pressing the infusion bag opening down from one side of the arc-shaped opening 1322, the infusion bag opening squeezes the infusion bag clamps 132 on both sides. This causes the rollers 17 on both sides to drive the transmission rod 134 to compress the torsion spring 137 and move it towards the center of the waist-shaped groove. Thus, the infusion bag opening is adaptively clamped onto the infusion bag clamps 132 on both sides under the elastic force of the torsion spring 137. The multi-position slot 1323 fits together, thereby improving the installation speed of the infusion bag and enhancing the stability of the infusion bag clamping, which facilitates the subsequent drug preparation operation. One side of the infusion bag clamping block 132 is provided with a limiting rod 1324 for limiting the distance between the two sides of the infusion bag clamping blocks 132, and the other side of the infusion bag clamping block 132 is provided with a limiting hole 1325 corresponding to the guide rod. By setting the limiting rod 1324, the arc-shaped openings 1322 on the two sides of the infusion bag clamping blocks 132 are prevented from colliding under the action of the torsion spring 137, thereby causing the arc-shaped openings 1322 to deform or wear.
[0040] Specifically, the mounting block 131 is provided with a threaded hole 1311 for mounting the torsion spring 137. One end of the torsion spring 137 is mounted on the mounting block 131 by a bolt 24. The transmission rod 134 is provided with a threaded hole 1342 for mounting the torsion spring 137 at the end away from the threaded hole 1311. The other end of the torsion spring 137 is mounted on the transmission rod 134 by a bolt 25. The cylindrical surface of the mounting block bolt 135 located on the outer side of the mounting block 131 is a smooth cylindrical surface. The outer circular wall of the roller 133 is tangent to the inner wall of the waist-shaped groove 1321. Thus, during the adaptive clamping of the infusion bag opening, the infusion bag clamping blocks 132 on both sides slide synchronously along the guide rail 121 under the drive of the slider 122, and finally clamp the infusion bag opening.
[0041] like Figure 8 and 9 As shown, specifically, the drive assembly 16 includes a push rod 161 connected to the guide slide assembly 15. One end of the push rod 161 is connected to the inner wall of the mounting base housing 18 via a push rod spring 162. A limiting block 163 is provided at the end of the push rod 161 near the push rod spring 162 to limit the sliding distance of the push rod 161. A connecting block 164 is provided at the other end of the push rod 161. A through hole 1641 is provided on the side of the connecting block 164 away from the push rod 161. A handle 165 is movably provided on the side of the mounting base 11 near the connecting block 164. The handle 165 is stepped. The end of the handle 165 with a smaller diameter passes through the through hole 1641. From the inside to the outside, a handle glove 166, a locking block 167, a locking block spring 168, and a limiting nut 169 are sequentially fitted onto the end of the handle 165 passing through the through hole 1641.
[0042] like Figure 11As shown, specifically, the handle 165 has a thread at one end of the through hole 1641. The side of the handle 165 away from the connecting block 164 has a mounting platform 1651 for installing the handle sleeve 166. By setting the handle sleeve 166, the sliding stroke of the handle 165 is increased. The locking block 167 is locked onto the handle 165 by anti-loosening nuts 1652 on both sides. One side of the locking block spring 168 abuts against the locking block 167, and the other side abuts against the connecting block 164. By setting the locking block spring 168 between the locking block 167 and the mounting block 131, the sliding stroke of the handle 165 is increased. When the locking block 167 is released from the locking cavity 141, it buffers the instantaneous release of the spring force of the push rod spring 162, thereby improving the stability of the device. At the same time, when the locking block 167 is engaged in the locking cavity 141, the locking block spring 168 can squeeze the locking block 167, so that the locking block 167 is tightly attached to the side wall of the locking cavity 141, preventing the locking block 167 from falling out of the locking cavity 141 and improving the reliability of the device. The limiting nut 169 is provided at one end of the handle 165 through the second through hole 1641 to prevent the handle 165 from falling off the connecting block 164.
[0043] Specifically, the roller 17 is located on the top of the push rod 161 and between the infusion bag clamps 132 on both sides. One end of the push rod 161 and the inner wall of the mounting base housing 18 on the same side are provided with mounting posts 20 for mounting the push rod spring 162.
[0044] like Figure 6 As shown, specifically, the motion cavity 14 has a locking cavity 141 on the side near the handle 165 corresponding to the latch block 167. The locking cavity 141 is L-shaped. The mounting base 11 and the mounting base housing 18 are both provided with guide grooves 21 on the side near the locking cavity 141 for restricting the handle 165 to slide on the mounting base 11. The mounting base 11 has handle blocks 22 at both ends for moving the mounting base 11. The bottom of the handle blocks 22 has a slot 23 for locking the mounting base 11 in the next working position.
[0045] Specifically, the mounting base 11 is modular, preferably a secondary modular design. By quickly and easily replacing the mounting base 11, the infusion bag can be clamped onto the mounting base 11, thereby enabling uninterrupted medication preparation of the infusion bag and further improving the efficiency of medication preparation.
[0046] Specifically, the top of the mounting base housing 18 is sloped towards the mounting block 131, and the clamping frame 19 is disposed on the sloped surface of the mounting base housing 18.
[0047] Specifically, the clamping frame 19 is located directly above the clamping assembly 13, the clamping part of the clamping frame 19 is U-shaped, and the material of the clamping part of the clamping frame 19 is an elastic material.
[0048] Specifically, the infusion bag clamp 132 is threadedly connected to the slider 122, and the push rod 161 is threadedly connected to the slider 2 152.
[0049] Working principle of the invention: Before use, the two rollers 133 are at their extreme positions in the waist-shaped groove 1321 on the same side, and the end of the limiting rod 1324 abuts against the bottom wall of the limiting hole 1325. The push rod spring 162 is in normal condition, the limiting block 163 on the push rod 161 abuts against the end of the guide rail 151, the roller 17 is located at the center of the two infusion bag clamping blocks 132, the locking spring 168 is in normal condition, the locking block 167 is located at the horizontal position of the locking cavity 141, and the limiting nut 169 abuts against the connecting block 164. During use, by pressing the infusion bag opening down from one side of the arc-shaped opening 1322, the infusion bag opening squeezes the two infusion bag clamping blocks 132 on both sides, causing the two rollers 133 to drive the transmission rod 134 to compress the torsion spring 137 towards the waist-shaped groove 132. The central part moves, thereby driving the two side infusion bag clamping blocks 132 to move synchronously along the guide rail 121 via the slider 122, so that the infusion bag opening is fully fitted with the multi-position slot 1323. At the same time, the two side infusion bag clamping blocks 132 adaptively clamp the infusion bag opening under the elastic force of the torsion spring 137, and then clamp the infusion bag body onto the clamping frame 19, thus completing the bag loading and clamping operation of the infusion bag. During the adaptive clamping process of the infusion bag, by using the multi-position slot 1323 that matches the opening of different models of infusion bags, the bag loading and clamping operation of different models of infusion bags can be realized, thereby improving the speed of infusion bag installation and the flexibility of the device, and also improving the stability of infusion bag clamping, which facilitates the subsequent drug preparation operation. After the infusion bag is prepared for drug preparation, By pushing the handle 165 along the guide groove 21 towards the push rod 161, the push rod 161 is pushed to compress the push rod spring 162, causing the locking block 167 to move from the horizontal position of the locking cavity 141 to the vertical position. At the same time, the roller 17 pushes the infusion bag clamping block 132 to move, causing the two rollers 133 on both sides to move towards the center along the waist-shaped groove 1321 on the same side, thereby quickly opening the infusion bag clamping block 132. By rotating the handle 165, the locking block 167 is then locked into the vertical position of the locking cavity 141. Under the elastic force of the locking block spring 168, the locking block 167 is tightly attached to the vertical side wall of the locking cavity 141, thus preventing the locking block 167 from falling out of the locking cavity 141 and improving the reliability of the device. Then, the infusion bag with the prepared medicine is removed, thus completing the bag insertion. In operation, when all the infusion bags have been removed, the handle 165 is rotated in the opposite direction, causing the locking block 167 to disengage from the vertical position of the locking cavity 141 to the horizontal position. At this time, the locking block spring 168 buffers the instantaneous release force of the push rod spring 162, thereby reducing the impact force generated by the instantaneous release force of the push rod spring 162 and improving the stability of the device. Under the elastic force of the push rod spring 162, the push rod 161 pushes the handle 165, causing the locking block 167 to move along the horizontal part of the locking cavity 141, thereby causing the handle 165 to quickly return to its original position. At the same time, the limiting block 163 on the push rod 161 abuts against the guide rail 151, causing the push rod spring 162 to drive the push rod 161 to quickly return to its original position, thereby causing the roller 133 to move away from the infusion bag clamping block 132.The infusion bag clamp 132 is reset under the elastic force of the torsion spring 137, thereby quickly resetting the entire device.
