Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a vial clamping device capable of firmly clamping a vial. Background Art

[0002] Currently, intravenous medication dispensing in hospitals is primarily performed manually by medical staff. Due to the high demand for intravenous medication across various hospital departments, manual operation not only consumes significant manpower and material resources, but also increases the risk of harming nursing staff and contaminating medication solutions. With the advancement of robotics, intravenous medication dispensing robots are gradually becoming available. These robots can automatically obtain prescriptions and dispense medications, significantly reducing these risks.

[0003] For example, Chinese patent 201811309300.2 discloses a quick clamping device for a syringe bottle, comprising a left clamping jaw and a right clamping jaw, which are respectively fixed to a fixed plate by a left clamping jaw connecting rod and a right clamping jaw connecting rod. The left clamping jaw connecting rod and the right clamping jaw connecting rod are U-shaped structures, one end of which is connected to one end of the left clamping jaw and the right clamping jaw respectively, and the other end is rotatably connected to the fixed plate by a rotating shaft. A connecting rod limit spring is connected between the left clamping jaw connecting rod and the right clamping jaw connecting rod, and a convex structure is provided at the end of the right clamping jaw connecting rod, which engages with the convex structure of the linkage block located at the bottom of the right clamping jaw connecting rod. A spring fixing block is provided under the linkage block, and a linkage block limit spring is inserted into the limiting hole of the spring fixing block. One end of the linkage block limit spring is fixed to the bottom of the fixed plate by a spring fixing block fixing pin, and the other end is fixed to the bottom of the linkage block. The spring fixing block is connected to the linkage block by a linkage block fixing pin.

[0004] The clamping device for clamping a vial in the prior art does not have a locking position. That is, when the clamped vial receives an external force during the puncture process, the clamping of the vial may easily become unstable due to the external force, or even cause the vial to fall off, resulting in a low puncture success rate.

[0005] Based on this, the present application provides a vial clamping device with a locking function at the puncture station to solve the problem of the vial being pushed out of the clamping claws during the puncture process. Summary of the Invention

[0006] In view of the defects of the prior art, the present invention provides a vial clamping device, which can lock the clamping claw assembly matched therewith to solve the problem of the vial being ejected during the puncture process in the prior art.

[0007] In order to achieve the above object, the present invention provides a vial clamping device, comprising:

[0008] Install the base;

[0009] The medicine storage turntable is arranged on the mounting base and can rotate relative to the mounting base;

[0010] A plurality of clamping jaw assemblies are arranged on the medicine storage turntable and rotate synchronously with the medicine storage turntable to switch the positions of the plurality of clamping jaw assemblies;

[0011] The clamping jaw assembly includes a self-resetting hand claw, a thrust member and a thrust spring. The thrust member is arranged on the medicine storage turntable and has an ejection position and a retraction position. The thrust spring is arranged on the medicine storage turntable and can keep the thrust member in the retraction position.

[0012] The thrust member is provided with a clamping portion, and the self-resetting hand claw is provided with a clamping fitting portion, and the clamping portion on the thrust member in the pushing position is engaged with the clamping fitting portion; and

[0013] A locking member for switching the thrust member from a retracted position to an ejected position is fixedly arranged on the mounting base.

[0014] In the above technical solution of the present invention, the multiple clamping claw assemblies rotate along with the medicine storage turntable to switch positions, thereby facilitating the bottle placing operation.

[0015] Furthermore, a single clamping jaw assembly will be locked only when it is at a specified position, that is, when the thrust member contacts the locking member and the snap-fit ​​portion is engaged with the snap-fit ​​portion. At this time, the clamping jaw assembly cannot perform bottle placing and unloading operations.

[0016] Specifically, the position of the locking member is fixed and does not rotate with the rotation of the medicine storage turntable. The clamping jaw assembly rotates with the rotation of the medicine storage turntable, thereby switching the designated clamping jaw assembly to a locked state for puncture.

[0017] According to another specific embodiment of the present invention, an abutment portion cooperating with the locking member is provided on the thrust member. As the medicine storage turntable rotates, the thrust member has a position where the abutment portion abuts against the locking member and changes position. The locking member drives the thrust member through the abutment portion to overcome the force of the thrust spring and switch from the retracted position to the pushed-out position, thereby locking the clamping claw corresponding to the thrust member.

[0018] According to another specific embodiment of the present invention, the engaging portion is a rack, and the engaging portion is a locking tooth that engages with the rack, and the two engage with each other to form a position-limiting locking structure.

[0019] According to another specific embodiment of the present invention, the locking member is a locking spring, and the thrust provided by the locking spring is greater than the pulling force provided by the thrust spring. As the medicine storage turntable rotates, the position between the thrust member and the locking member becomes non-contact, and the thrust spring provides a force to switch the thrust member from the push-out position to the retracted position.

[0020] According to another specific embodiment of the present invention, the thrust member is switched between the pushed-out position and the retracted position in a rotational manner or a sliding manner.

[0021] According to another specific embodiment of the present invention, the self-resetting type includes:

[0022] Slide rails;

[0023] Two sliders are slidably arranged on the slide rails;

[0024] Two clamping claws are respectively arranged on two sliders;

[0025] A spring, with both ends of the spring connected to the two sliders; and

[0026] The two fork members can make the two sliders slide synchronously. The two fork members are installed on the medicine storage turntable through a rotating shaft. The synchronous rotation of the two fork members around the rotating shaft can drive the two sliders to produce opposite or reverse displacement.

[0027] In this solution, the two fork members cooperate to achieve synchronous sliding of the two, so as to ensure that the moving distances of the two sliders are consistent and the middle position does not change, thereby being suitable for clamping vials of different specifications.

[0028] According to another specific embodiment of the present invention, the fork member is V-shaped, comprising a corner portion, a first side portion, and a second side portion;

[0029] The corner part is mounted on the medicine storage turntable through a rotary shaft;

[0030] The first side portion is used to connect with the slider, and a first sliding groove is provided on the side portion. The slider is provided with a first connecting shaft located in the first sliding groove, and the first connecting shaft can rotate while sliding relative to the first sliding groove;

[0031] The second sides of the two fork members are connected to each other, the second side of one fork member is provided with a second sliding groove, and the second side of the other fork member is provided with a second rotating shaft, which is located in the second sliding groove and can rotate while sliding relative to the second sliding groove.

[0032] According to another specific embodiment of the present invention, a plurality of clamping jaw assemblies are arranged on both sides of the medicine storage turntable in a staggered manner, wherein the plurality of clamping jaw assemblies on the two sides are spaced apart from each other.

[0033] According to another specific embodiment of the present invention, two medicine storage turntables are provided, one at a high position and the other at a low position, and a switching assembly for switching the high and low positions of the two medicine storage turntables;

[0034] The switching assembly includes a fixed base, a connecting bracket, a turntable, and a rotary motor for driving the turntable to rotate. The rotary motor is arranged on the fixed base, the bracket is arranged on the turntable, and the two medicine storage turntables are fixed to the connecting bracket through different mounting bases.

[0035] The two medicine storage turntables can rotate 180° around the turntable, so that the positions of the two medicine storage turntables can be interchanged.

[0036] Specifically, the two medicine storage turntables are symmetrically centered around the turntable, and the turntable is driven to rotate by a rotary motor, thereby driving the rotation of the connecting bracket, thereby realizing the interchange of the positions of the two medicine storage turntables.

[0037] Among them, the bottle mouths of the penicillin bottles on the lower storage turntable are facing upward, and the bottle mouths of the penicillin bottles on the higher storage turntable are facing downward, so as to facilitate direct suction and injection operations on the penicillin bottles.

[0038] According to another specific embodiment of the present invention, an automatic bottle unloading assembly is further included, which is arranged near the medicine storage turntable located at a lower position. The automatic bottle unloading assembly includes:

[0039] A mounting bracket is provided on a fixed base;

[0040] A slide rail and slider member is slidably mounted on the mounting bracket; and

[0041] The bottle unloading lever has a middle portion which is rotatably arranged on the mounting bracket via a swing shaft;

[0042] Among them, the working end of the bottle unloading rod is set close to the clamping claw in the bottle unloading position, and the connecting end of the bottle unloading rod is connected to the slider in the slide rail slider component. The relative position between the working end of the bottle unloading rod and the clamping claw in the bottle unloading position can be changed by sliding the slider.

[0043] The present invention has the following beneficial effects:

[0044] The vial clamping device of the present invention is capable of locking the clamping assembly at a specified position by arranging a thrust member and a thrust spring on the clamping jaw assembly and a locking member on the mounting base, thereby stabilizing the clamping jaws in the clamping jaw assembly, giving it a greater clamping force, and avoiding the phenomenon of the vial being pushed out of the clamping jaws during the puncture of the vial.

[0045] In addition, in the solution of the present invention using the latching teeth to form the latching portion and the rack to form the latching fitting portion, there is a stable latching relationship between the two, the structure is stable, and the locking effect is good.

[0046] In addition, the thrust provided by the locking spring of the present invention is greater than the pulling force provided by the thrust-stop spring. When the vial is subjected to a force far exceeding the set force, the locking spring will deform, thereby eliminating the restriction on the vial and playing a protective role.

[0047] In addition, the present invention also provides a fork component, which can effectively stabilize the relative sliding process between the two sliders, keep the clamping center of the clamping claws constant, achieve automatic centering, and facilitate clamping of vials of different specifications.

[0048] In addition, the present invention has two medicine storage turntables, which can process the vials (at the high position) while performing bottle unloading and bottle placement operations (at the low position), greatly improving work efficiency. Moreover, the prescriptions that can be prepared are not limited by the number of vials, and medicines can be placed indefinitely until the dispensing is completed.

[0049] At the same time, an automatic bottle unloading component is also provided, which can automatically unload the bottles, is easy to operate, and has a high degree of automation.

[0050] The present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Example 1

[0064] A vial clamping device, such as Figure 1 As shown in FIG. 9 , it includes a mounting base 100 , a medicine storage turntable 200 , six clamping jaw assemblies 300 and a locking member 400 .

[0065] The medicine storage turntable 200 is set on the mounting base 100, and is driven by a rotating motor 110 to realize self-rotation. The medicine storage turntable 200 is hexagonal in shape as a whole, and the six clamping jaw assemblies 300 are arranged in the area where the six edges are located. The locking member 400 is fixed to the medicine storage turntable 200, for example, by a bracket. The six clamping jaw assemblies 300 are respectively cooperated with the locking member 400 through the rotation of the medicine storage turntable 200, and the six clamping jaw assemblies 300 are respectively locked.

[0066] See also Figure 3 、 Figure 4 The clamping jaw assembly 300 includes a self-resetting jaw 310, a thrust member 320 and a thrust spring 330, wherein the self-resetting jaw 310 is used to clamp the syringe bottle, the thrust member 320 is arranged on the medicine storage turntable 200, and has a push-out position and a retracted position, and the thrust spring 330 is arranged on the medicine storage turntable 200 and can keep the thrust member 320 in the retracted position.

[0067] A snap-fit ​​portion 321 is provided on the thrust member 320, and a snap-fit ​​portion 311 is provided on the self-resetting hand claw 310. The locking member 400 is used to offset the force of the thrust spring 330 and switch the thrust member 320 from the retracted position to the pushed-out position. The snap-fit ​​portion 321 on the thrust member 320 in the pushed-out position is engaged with the snap-fit ​​portion 311 to lock the self-resetting hand claw 310. At this time, the two clamping jaws in the self-resetting hand claw 310 cannot open or close and are in a stable clamping state.

[0068] Specifically, when the self-resetting claw 310 is in any clamping configuration, it can be locked into the corresponding clamping configuration by the thrust member 320 and the locking member 400 in the pushing position.

[0069] See also Figure 4 — Figure 9 The thrust member 320 is rotatably mounted on the mounting base 100 via a hinge point 322 , and is further provided with an abutment portion 323 , wherein the engaging portion 321 is a locking tooth, the engaging fitting portion 311 is a rack 311 a , and the abutment portion 323 is a straight rod.

[0070] As the medicine storage turntable 200 rotates, each clamping jaw assembly 300 has such a position, where the abutting portion 323 contacts and abuts against the locking member 400. Driven by the locking member 400, the thrust member 320 is forced to stretch the thrust spring 330 and rotate around the hinge point 322, driving the clamping portion 321 to rotate toward the self-resetting hand claw 310. The thrust member 320 switches from the retracted position to the push-out position and engages with the clamping fitting portion 311, thereby achieving a limited locking of the self-resetting hand claw 310.

[0071] The locking member 400 in this example can be a locking spring, wherein the thrust provided by the locking spring is greater than the pulling force provided by the thrust spring 330. As the medicine storage turntable 200 rotates, the position between the thrust member 320 and the locking member 400 becomes non-contact, and the thrust spring 330 provides a force to switch the thrust member 320 from the push-out position to the retracted position. At this time, the self-resetting gripper 310 releases the lock, and normal bottle placing and unloading operations can be performed.

[0072] The self-resetting gripper 310 in this example only needs to be able to achieve automatic reset. The two jaws in the self-resetting gripper 310 preferably have a synchronous sliding structure to form a good clamping effect, that is, a single jaw can be locked to achieve complete locking.

[0073] This example provides a preferred self-resetting gripper 310 including a slide rail 312, two sliders 313, two clamping jaws 314, a spring (not shown in the figure) and a fork member 340, wherein the slide rail 312 is a linear slide rail, which is arranged along the side of the medicine storage turntable 200, and the rack 311a is parallel to the linear slide rail. The two clamping jaws 314 are respectively arranged on the two sliders 313 so as to be able to open or clamp the syringe bottle along the slide rail 312, and the fork member 340 is used to make the two sliders 313 slide synchronously.

[0074] See also Figure 4 、 Figure 5 The fork member 340 is V-shaped and includes a corner portion 341 , a first side portion 342 , and a second side portion 343 ;

[0075] A connecting hole is provided at the corner portion 341, which is mounted on the medicine storage turntable 200 via the rotary shaft 201;

[0076] The first side portion 342 is used to connect with the slider 313 and has a first sliding groove 344 formed thereon. The slider 313 has a first connecting shaft 345 located in the first sliding groove 344. The first connecting shaft 345 can rotate while sliding relative to the first sliding groove 344.

[0077] The second sides 343 on the two fork members 340 are connected to each other. The second side 343 of one fork member 340 is provided with a second sliding groove 346, and the second side 343 of the other fork member 340 is provided with a second rotating shaft 347. The second rotating shaft 347 is located in the second sliding groove 346 and can rotate while sliding relative to the second sliding groove 346.

[0078] The synchronous rotation of the two fork members 340 around the rotary shaft 201 can drive the two sliders 313 to synchronously move toward or away from each other, ensuring that the movement distances of the two sliders 313 are consistent and the intermediate positions do not change, thereby being suitable for clamping vials of different specifications.

[0079] To facilitate the distribution of the jaw assemblies 300, in this example, two adjacent jaw assemblies 300 are respectively located on both side surfaces of the medicine storage turntable 200, and the six jaw assemblies 300 are arranged in an staggered manner on both side surfaces of the medicine storage turntable 200, and the six jaw assemblies 300 located on both side surfaces are spaced apart.

[0080] Specifically, the mounting base 100 of this example is further provided with a sensor 120 for detecting whether a single clamping jaw assembly 300 is clamping a vial.

[0083] The switching assembly 500 is used to switch the two medicine storage turntables 200 between a high position and a low position, and includes a fixed base 510, a connecting bracket 520, a turntable 530, and a rotary motor 540. The rotary motor 540 is arranged on the fixed base 510 and is used to drive the turntable 530 to rotate. The two medicine storage turntables 200 are fixed on the connecting bracket 520 through different mounting bases 100. The medicine storage turntables 200 are distributed with the turntable 530 as the symmetrical center. The turntable 530 is driven to rotate by the rotary motor 540, which drives the rotation of the connecting bracket 520, thereby realizing the interchange of the positions of the two medicine storage turntables 200.

[0084] The automatic bottle unloading assembly 600 is used to automatically unload bottles from the medicine storage turntable 200 in a low position. It includes a mounting bracket 610, a slide rail slider component 620, and a bottle unloading lever 630. The mounting bracket 610 is set on the fixed base 510, the slide rail slider component 620 is set on the mounting bracket 610, and the middle part of the bottle unloading lever 630 is rotated on the mounting bracket 610 through a swing axis.

[0085] Among them, the working end 631 of the bottle unloading rod 630 is set close to the clamping claw in the bottle unloading position, and the connecting end 632 of the bottle unloading rod 630 is connected to the slider in the slide rail slider component 620. The relative position between the working end 631 of the bottle unloading rod 630 and the clamping claw in the bottle unloading position can be changed by sliding the slider.

[0086] Specifically, a third slide groove 633 is provided at the connecting end 632 of the bottle unloading lever 630, and a third rotating shaft 634 is provided on the slider in the slide rail slider assembly 620. The third rotating shaft 634 is located in the third slide groove 633. As the slider in the slide rail slider assembly 620 extends, the position of the working end 631 of the bottle unloading lever 630 is changed.

[0087] Furthermore, in this example, the extension and retraction of the slider in the slide rail slider assembly 620 are driven by the motor screw 640.

[0088] Accordingly, the bottle unloading lever 630 may adopt a segmented structure with upper and lower offsets, such as Figure 12 As shown, to simplify the installation structure.

[0089] Although the present invention is disclosed above with reference to preferred embodiments, this is not intended to limit the scope of the present invention. Any person skilled in the art may make slight modifications without departing from the scope of the present invention. In other words, any equivalent modifications made in accordance with the present invention should be included within the scope of the present invention.
