Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular is an automatic capping and disinfecting device for medicine vials. Background Art

[0002] Vials, also known as borosilicate glass or soda-lime glass controlled injection bottles, are small bottles sealed with a rubber stopper and an aluminum-plastic combination cap. They are named because they were used to hold penicillin in the early days. As an indispensable drug packaging container in the modern medical industry, the smoothness and efficiency of the opening and collection process of vials are directly related to the convenience and safety of drug use.

[0003] Most of the vial decappers on the market are designed for two-handed operation, which means that during the decapping process, the operator needs to use both hands at the same time to hold the vial and perform the decapping action. In the batch processing scenario of centralized preparation of intravenous medication, this two-handed operation method greatly limits work efficiency, because only one vial can be processed at a time, and multiple vials cannot be processed at the same time, resulting in a reduction in overall processing speed. After decapping, the vial caps usually need to be collected and discarded manually. This step is not only cumbersome, but also easily causes the caps to scatter during operation, increasing the difficulty of cleaning and sorting. Especially in batch processing, manual collection of bottle caps is inefficient and prone to errors, further increasing the intensity and difficulty of work.

[0004] Especially in the centralized drug dispensing center of medical institutions, the workload of opening and collecting vials is large and frequent, which places higher requirements on the performance of the opening and collecting device. Existing opening and collecting devices are often inefficient in batch processing, and are prone to causing bottle caps to scatter and drug contamination, which cannot meet the needs of efficient, safe and sterile drug processing.

[0005] In view of the shortcomings of existing technologies, there is an urgent need for a more efficient, intelligent and automated vial opening and collection device to meet the needs of centralized preparation of intravenous medications. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide an automatic uncapping and disinfecting device for pharmaceutical vials, which can automatically complete the uncapping and bottle cap collection work of the vials, reduce manual intervention and improve processing efficiency.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows:

[0008] The invention discloses an automatic decapping and disinfecting device for medicine vials, comprising a decapping box; the decapping box comprises a box body and a cover body, and the box body and the cover body are detachably connected; a rotating groove is arranged on the top of the box body, a turntable is rotated in the rotating groove, a plurality of receiving grooves for placing vials are circumferentially arranged on the turntable, suction cups are arranged at the bottom of the receiving grooves, and the suction cups are respectively connected to negative pressure components, and the negative pressure components are used to generate negative pressure; a transmission component is also arranged in the rotating groove, and the transmission component is used to drive the turntable to rotate and the negative pressure component to operate at the same time; an decapping component is arranged on the cover body, and a collecting component is also arranged in the box body, the decapping component is used to take out the vial caps in the receiving grooves, and the collecting component is used to collect the vial caps.

[0009] The above scheme has the following beneficial effects:

[0010] 1. This solution places the cap of the vial in the receiving tank, uses the transmission component to drive the turntable to rotate, and at the same time drives the negative pressure component at the bottom of the receiving tank to generate negative pressure, uses the suction cup to fix the bottom of the vial, and then removes the cap of the vial through the opening assembly, and then collects the removed cap through the collection assembly.

[0011] In this solution, a plurality of vials can be accommodated at the same time by means of the accommodating grooves arranged circumferentially on the turntable, and the turntable can be driven by the transmission assembly to rotate continuously to achieve batch processing.

[0012] 2. This solution realizes the full automation of vial capping and bottle cap collection by integrating a turntable, a negative pressure component, a transmission component, a capping component and a collection component.

[0013] The automated design allows operators to simply place vials into the holding tank and start the device without complicated operations or adjustments. This reduces the difficulty of operation, allowing more people to easily get started and complete their work efficiently. It is particularly suitable for centralized drug dispensing centers with large workloads and frequent visits.

[0014] Furthermore, the negative pressure assembly includes a piston column; a plurality of negative pressure grooves are circumferentially arranged at the bottom of the turntable, the negative pressure grooves correspond to the accommodating grooves one by one, and the negative pressure grooves are respectively connected to the accommodating grooves; the piston columns are respectively slidably matched with the negative pressure grooves, and a locking groove is arranged on one side of the bottom of the piston column.

[0015] Beneficial effect: By moving the piston column outward, the volume between the negative pressure groove and the piston column increases, thereby generating negative pressure, which in turn acts on the suction cup, causing the suction cup to generate adsorption force to firmly fix the vial.

[0016] Furthermore, the transmission assembly includes a transmission shaft and a driving member; a spiral plate is provided on the transmission shaft, and the spiral plate is arranged circumferentially along the length direction of the transmission shaft; a convex strip is provided on one side of the spiral plate, and the convex strip is arranged circumferentially along the length direction of the transmission shaft, and the distance between the convex strip and the transmission shaft is in a linearly changing relationship, and the convex strip is slidably matched with the engaging groove in turn; the driving member is used to drive the transmission shaft to rotate.

[0017] Principle: By starting the driving member, the driving member drives the transmission shaft to rotate, and the transmission shaft rotates synchronously with the spiral plate and the convex strip. During the rotation of the convex strip, the piston column will be pushed to rotate. At the same time, since the distance between the convex strip and the transmission shaft gradually decreases, the convex strip will provide a downward squeezing force while sliding with the engaging groove, causing the piston column to move downward, thereby generating negative pressure in the negative pressure groove.

[0018] Beneficial effects: By starting the driving member, the transmission shaft can drive the spiral plate and the convex strip to rotate synchronously. The convex strip slides with the engaging groove during rotation, pushing the piston column to rotate and generate downward extrusion force. This precise driving mechanism ensures that the piston column can move according to the predetermined trajectory and speed, thereby generating the required negative pressure in the negative pressure groove.

[0019] The distance between the cam and the drive shaft changes linearly, which means that as the cam rotates, it can gradually reduce the gap between it and the piston rod, thereby providing a gradually increasing downward extrusion force. This adaptive adjustment mechanism helps ensure that the piston rod can move smoothly and continuously, avoiding shock and vibration caused by sudden increases in extrusion force.

[0020] Furthermore, the cover opening assembly includes a mobile carrier and a lifting assembly; a cover opening groove is also provided in the cover body, and the cover opening groove is located above the turntable; the top wall of the cover opening groove is connected with the lifting groove, and the mobile carrier is slidably matched with the lifting groove, and at least one sliding groove is provided at the bottom of the mobile carrier, and a pair of sliders are slidably matched in the sliding groove, and springs are provided between the sliders, and inclined plates are respectively provided at the bottom of the sliders, and clamping blocks for clamping the caps of the vials are provided at the bottom of the inclined plates; the lifting assembly is used to drive the mobile carrier to achieve lifting.

[0021] Beneficial effect: The lifting component drives the movable carrier to move up and down, and the movable carrier drives the slider, the inclined plate and the clamping block to move up and down synchronously. The distance between the clamping blocks is changed by the change of the distance between the inclined plate when passing through the notch of the lifting slot, so as to complete the clamping and release of the vial cap.

[0022] Furthermore, the lifting component includes a cylinder; a movable groove is connected to one side of the lifting groove, and both ends of the cylinder are rotatably connected to the inner wall of the movable groove respectively; spiral grooves are symmetrically arranged on the outside of the cylinder, and the spiral grooves are staggered and connected to each other; a convex rod is arranged on the side of the movable groove close to the movable groove of the movable carrier, and the convex rod is slidably matched with the spiral groove; a linkage component is also arranged at one end of the cylinder, and the linkage component is used to realize the linkage between the transmission shaft and the cylinder.

[0023] Beneficial effect: The power of the transmission shaft is transmitted to the cylinder through the linkage assembly, and the rotation of the cylinder drives the convex rod to slide along the spiral groove, thereby driving the mobile carrier to move up and down.

[0024] Furthermore, the linkage assembly includes a transmission rod; the transmission rod is coaxially fixedly connected to the cylinder, the other end of the transmission rod extends into the rotating groove, a first bevel gear is provided at one end of the transmission rod away from the cylinder, the first bevel gear is meshed with a second bevel gear, and the second bevel gear is axially fixedly connected to the transmission shaft.

[0025] Beneficial effect: When the transmission shaft rotates, it will drive the second bevel gear to rotate, the second bevel gear will drive the first bevel gear to rotate, the first bevel gear will drive the transmission rod to rotate, the transmission rod will drive the cylinder to rotate, so as to realize the linkage between the transmission shaft and the cylinder. Through the design of the linkage component, the opening process of the vial does not need to set up an additional power device, and the operation of the entire device can be realized only by the driving part.

[0026] Furthermore, the collecting assembly includes a carrying plate, a connecting rod and a support rod; a collecting trough is also provided in the box body, and the collecting trough is connected with the cover opening trough; the carrying plate is located at the connecting point between the cover opening trough and the collecting trough; the top of the support rod is rotatably connected with the top of the cover opening trough, and the bottom of the support rod is rotatably connected with the top of the carrying plate; the top of the connecting rod is rotatably connected with the clamping block close to one side of the collecting trough, and the bottom of the connecting rod is rotatably connected with the top of the carrying plate.

[0027] Beneficial effect: When the clamping block moves upward while holding the bottle cap, the bearing plate will deflect clockwise through the transmission of the connecting rod, preparing for the release of the bottle cap. When the clamping block releases the bottle cap downward, the bottle cap can just fall onto the bearing plate and slide into the collection tank through the bearing plate under the action of its own gravity, realizing the automatic collection of the bottle cap.

[0028] The design of the collection assembly cleverly combines the structures such as the carrier plate, connecting rod and support rod to form an efficient bottle cap collection system. This design not only reduces manual intervention and improves collection efficiency, but also maintains the compactness and stability of the device.

[0029] Furthermore, tension springs are respectively arranged between the piston column and the negative pressure groove.

[0030] Beneficial effect: When the engagement groove in one of the piston rods is separated from the convex strip, the tension spring can quickly pull the piston rod back to its original position, thereby releasing the suction cup from fixing the vial. This design makes the fixing and releasing process of the vial faster and more efficient, reducing manual intervention and downtime. During the entire process of the turntable rotating, the piston rod can automatically fix and release the vial as it passes before and after the convex strip. This automated and intelligent design enables the device to operate continuously and stably, improving production efficiency and product quality.

[0031] Furthermore, a disinfection nozzle for spraying disinfectant is also provided on the top of the lid opening groove.

[0032] Beneficial effect: By providing a disinfection nozzle, the vials sent into the capping slot can be disinfected, which helps to reduce microbial contamination on the surface of the vials, improve the sanitary quality of the vials, and thus ensure the safety and effectiveness of the drugs.

[0033] Furthermore, elastic anti-skid pads are provided on the inner sides of the clamping blocks.

[0034] Beneficial effect: By providing an elastic anti-skid pad, the clamping force of the clamping block on the cap of the vial is increased to prevent the cap from slipping or being damaged during the opening process. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The specific implementation process is as follows:

[0055] The medical staff puts the vials to be opened into the receiving groove 201 one by one, and then starts the stepper motor. The stepper motor drives the transmission shaft 3 to rotate. During the rotation of the transmission shaft 3, the spiral plate 301 and the convex strip 302 are driven to rotate. During the rotation of the convex strip 302, the convex strip 302 continuously pushes the piston column 204 to deflect along the tangential direction of the turntable 2. At this time, the piston column 204 in contact with the convex strip 302 will be subjected to the continuous downward squeezing force of the convex strip 302, so that the piston column 204 moves downward, and then negative pressure is generated in the negative pressure groove 203, and acts on the suction cup 202 corresponding to the piston column 204, and the suction cup 202 will adsorb and fix the bottom of the vial in the corresponding receiving groove 201.

[0056] At the same time, the transmission shaft 3 also drives the first bevel gear 119 and the second bevel gear 303 to rotate, thereby driving the transmission rod 114 to rotate, the transmission rod 114 drives the cylinder 112 to rotate, and the cylinder 112 drives the piston carrier to move up and down. During the up and down movement of the piston carrier, the clamping block 116 is continuously driven to pull out the bottle cap of the cillin bottle (fixed by the suction cup 202) in the receiving groove 201. At the same time, when the clamping block 116 pulls out the bottle cap, the carrying plate 103 will move to the bottom of the clamping block 116 under the coordinated action of the connecting rod 104 and the strut 1041 (at this time, the left side of the carrying plate 103 is higher than the right side), until the clamping block 116 releases the bottle cap onto the carrying plate 103, and under the weight of the bottle cap itself, the bottle cap slides into the collecting groove 102, the clamping block 116 continues to move downward, and under the coordinated action of the connecting rod 104 and the strut 1041, the carrying plate 103 moves away from under the clamping block 116.

[0057] The turntable 2 continues to rotate, and after the vial in the receiving slot 201 is uncapped, the piston column 204 just below the receiving slot 201 just leaves the convex strip 302. After losing the restriction of the convex strip 302, the piston column 204 is reset under the negative pressure and the tension spring 5. At this time, the adsorption force generated by the suction cup 202 disappears until the receiving slot 201 corresponding to the suction cup 202 leaves the uncapping slot 101. The medical staff takes out the vial in the receiving slot 201 for use. The above process is repeated to uncap and collect the vial caps of batches of vials.

[0058] The only difference between the second embodiment and the first embodiment is that a disinfectant nozzle 4 for spraying disinfectant is further provided on the top of the lid opening groove 101 .

[0059] Specific implementation process: one or more disinfection nozzles 4 are added at the top of the lid opening groove 101, that is, near the edge of the container cover. In this embodiment, a disinfection nozzle 4 is provided. Specifically, in this embodiment, the disinfection nozzle 4 includes a pipeline and a disinfectant storage tank. The disinfection nozzle 4 is connected to the disinfectant storage tank through a pipeline to ensure a stable supply of disinfectant.

[0060] Before or after each opening of the lid, the disinfectant spray head 4 is manually or automatically controlled to spray disinfectant to the lid opening slot 101 and its surrounding area. This embodiment adds a disinfection function while maintaining the original performance, effectively reducing the risk of cross infection.

[0061] The only difference between Example 3 and Example 2 is that a plurality of telescopic grooves are arranged circumferentially in the receiving groove, and a telescopic assembly is arranged in the telescopic groove, and the telescopic assembly is used to adapt to different sizes of vials. Specifically, four telescopic grooves are arranged circumferentially in the receiving groove, and the telescopic assembly includes an elastic member and a clamping block. In this embodiment, the elastic member is a spring, and the clamping block is slidably matched with the telescopic groove. The elastic member is located between the clamping block and the telescopic groove, and the two ends of the elastic member are respectively welded and fixed to the clamping block and the side wall of the telescopic groove.

[0062] Specifically, when vials of different sizes are placed in the receiving slot, the surrounding of the vial body will contact the snap-fit ​​block and push the snap-fit ​​block back into the telescopic slot. The snap-fit ​​block can be adapted to vials of different sizes by different displacement distances in the receiving slot.

[0063] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
