Description

Technical Field

[0001] The present invention belongs to the technical field of medical device processing, and specifically relates to a pretreatment device for medical infusion bottles. Background Art

[0002] As a relatively common medical device in medical institutions, medical infusion bottles are mainly used to store and transport liquid drugs. In the modern medical infusion bottle manufacturing industry in medical institutions, materials such as polyvinyl chloride, polypropylene, and polyethylene are usually used for production, and they are manufactured into bottle bodies through blow molding, injection molding, or other processes. Such plastic medical infusion bottles generally have the advantages of being easy to carry, resistant to bumps and squeezes, and having low production costs.

[0003] And after subsequent use, they are generally directly sent to the factory for recycling. In the prior art, usually, the infusion bottles are cleaned, then broken and subjected to secondary processing. It should be noted that during the cleaning process, it is very difficult for disinfectants and cleaning agents to reach the inside of the infusion bottle from the bottle mouth for cleaning. If the remaining impurities dry up inside the bottle, it will be very difficult to clean them through ordinary technical means, which may lead to cross-contamination during subsequent crushing and secondary processing. Therefore, we provide a pretreatment device for medical infusion bottles. Summary of the Invention

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention cooperates with structures such as a cleaning component and a sorting component. When the hook passes over the bottle mouth, it returns to the initial position, and the bottom of the hook is embedded in the plastic bottle mouth and forces it to move. The water infused into the reciprocating threaded rod by the pump through the transfer box is sprayed toward the inner wall of the infusion bottle in multiple directions through the water trough, and the limiting plate makes the inner wall of the infusion bottle close to the water trough, so that the water pressure can better remove impurities. After cleaning is completed, the distance between each limiting plate becomes larger, and the inclined end of the hook is guided by the guide plate and is no longer embedded in the infusion bottle. The water pressure sprayed from the water trough can make each petal of plastic separate from the cleaning component as a whole, further improving the efficiency and quality of the cleaning device, so that the impurities on the inner wall of the infusion bottle can be cleaned more completely.

[0025] The present invention cooperates with structures such as a sorting component and a cleaning component. The motor drives the extrusion plate to swing back and forth through a reversing plate, a driving shaft and a guide rod. The infusion bottle surges toward the periphery of the docking device, and the top of the extrusion plate is always higher than the highest water level line, so that the infusion bottle will not be clamped between the extrusion plate and the inner wall of the working box. During the process of the sorting device driven by the driving shaft to rotate, the bottle mouth of the infusion bottle will be stuck in the notch of the docking device. The bottle body and the bottle mouth are designed with curved surfaces. After being pressed by the baffle, the bottle mouth can be better stuck in the notch, and then the infusion bottle is inserted into the reciprocating threaded rod, further improving the working efficiency and smoothness of the device, so that the device will not be stuck when in working state.

[0026] The present invention cooperates with structures such as a fishing component and a working box. When the infusion bottle is divided, a part of the aluminum foil used for sealing thereon may fall off. Although the density of the aluminum foil is greater than the density of water, the aluminum foil will not fall rapidly. As a result, the aluminum foil will be caught during the rotation of the arc plate driven by the central axis. When the arc plate touches the end of the retention plate, the aluminum foil on it will fall off and be located between the retention plate and the interlayer of the working box, further reducing the time and energy for subsequent manual collection of the aluminum foil.

DETAILED DESCRIPTION

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 8 shown, the present invention provides a medical infusion bottle pretreatment device, which includes a working box 1 and a motor 2 fixedly installed on the side of the working box 1. The inside of the working box 1 is filled with water, and further includes;

[0038] A transfer box 14 fixedly installed on the top of the working box 1;

[0039] A water pump 13 for pumping the water inside the working box 1 into the transfer box 14;

[0040] A plurality of cleaning components 6 axially and equidistantly arranged on the side of the transfer box 14;

[0041] The cleaning component 6 includes a positioning plate 61 fixedly installed on the side of the transfer box 14. A reciprocating threaded rod 62 is movably penetrated through the positioning plate 61. A second gear 63 is fixedly installed on the outer periphery of the reciprocating threaded rod 62. A plurality of guide plates 66 and limit plates 67 are respectively circumferentially and equiangularly fixedly installed on the outside of the positioning plate 61. A blade 68 is fixedly installed on the side of each limit plate 67. A limiter 65 is movably installed between every two adjacent limit plates 67;

[0042] The limiter 65 includes a transfer plate 651 threadedly connected to the outer periphery of the reciprocating threaded rod 62. A hook 653 is hinged on the transfer plate 651. The top of the hook 653 is elastically connected to the side of the transfer plate 651 through a second spring piece 652. Each transfer plate 651 is fixedly connected through a limit ring 64;

[0043] A sorting component 5 arranged inside the working box 1 and drivingly connected to the output shaft of the motor 2;

[0044] The sorting component 5 drives the second gear 63 in each cleaning component 6 to rotate through an adapter component 4;

[0045] The motor 2 is drivingly connected to a fishing component 3 through a belt 15;

[0046] The sorting component 5 is used to insert the mouth parts of each infusion bottle onto the reciprocating threaded rod 62.

[0047] One end of the hook 653 close to the positioning plate 61 is inclined. The limit ring 64 axially moves outside each limit plate 67. The transfer plate 651 is located between every two adjacent limit plates 67.

[0048] The end of the reciprocating threaded rod 62 is in a conical shape and is made of metal. The reciprocating threaded rod 62 is hollow and has a plurality of water grooves formed on its outer periphery. The interior of the reciprocating threaded rod 62 is connected to the interior of the transfer box 14 .

[0049] Adopt the above scheme: first, inject disinfectant and cleaning agent into the interior of the working box 1, and place the recovered infusion bottle into the interior of the working box 1. It should be noted that Figure 3 It can be observed that the interior of the working box 1 is separated from the sorting component 5 and the fishing component 3 by a partition, and the water level inside the working box 1 cannot exceed the height of the partition;

[0050] Then, the motor 2 is started to drive each gear 2 63 to rotate through the sorting component 5 and the adapter component 4. At the same time, the sorting component 5 will also insert the infusion bottle into the end of the reciprocating threaded rod 62;

[0051] Since the transfer plate 651 is not only inserted between every two adjacent limiting plates 67, but also threadedly installed on the surface of the reciprocating threaded rod 62, the limiter 65 can reciprocate during the process of the gear 2 63 driving the reciprocating threaded rod 62 to rotate. When the hook 653 passes over the bottle mouth, it will quickly return to the initial position. However, it should be noted that through the shape of the hook 653 and the elastic force of the spring sheet 2 652, its bottom will be embedded in the plastic bottle mouth and move with the plastic bottle mouth. The conical design of the end of the reciprocating threaded rod 62 can also make it easy to pierce the bottom of the infusion bottle. At the same time, the blade 68 will also divide a complete infusion bottle into several petals, and the reciprocating threaded rod 62 continues to rotate, which makes the water infused into the reciprocating threaded rod 62 by the pump 13 through the transfer box 14. It can be sprayed to the inner wall of the infusion bottle in multiple directions through the water tank, and after being restricted by the position of the limiting plate 67, it can also make the inner wall of the infusion bottle close to the water tank, so that the water pressure can better remove impurities;

[0052] After the infusion bottle is cleaned, the spacing between each limit plate 67 becomes larger, and the inclined end of the hook 653 is guided by the guide plate 66, so that the hook 653 is no longer embedded in the infusion bottle, and the water pressure sprayed by the water tank can make each petal of plastic separate from the cleaning component 6 as a whole. Furthermore, the limiter 65 continues to reciprocate, so that the cleaning work can be carried out continuously, and the efficiency and quality of the cleaning of the device are improved, so that the impurities on the inner wall of the infusion bottle can be cleaned more completely.

[0053] like Figures 1 - 5 As shown, the sorting assembly 5 includes a driving shaft 51 whose bearing is installed inside the working box 1, and a plurality of sorters 52 are installed at equal intervals on the outer circumference of the driving shaft 51;

[0054] On both sides of the driving shaft 51, a reversing plate 53 is eccentrically installed. One of the reversing plates 53 is drivingly connected to the output shaft of the motor 2, and the other reversing plate 53 movably penetrates through the side surface of the working box 1. A guide rod 54 is drivingly connected to the side surface of each reversing plate 53. A pressing plate 55 is hinged to the side surface of the working box 1, and the side surface of the pressing plate 55 is hinged to the two guide rods 54.

[0055] The sorter 52 includes a metal ring 521 fixedly installed on the outer periphery of the driving shaft 51. A plurality of connectors 522 are fixedly installed on the outer periphery of the metal ring 521 at equal angles in the circumferential direction. The connector 522 is provided with a notch adapted to the mouth of the infusion bottle. A baffle 11 is fixedly installed on the top of the working box 1. The baffle 11 is located obliquely above the driving shaft 51. Sorting plates 56 are equidistantly installed inside the working box 1. Each of the metal rings 521 is located between every two adjacent sorting plates 56.

[0056] Adopting the above scheme: Through Figure 2 and Figure 3 the motor 2 and the sorting assembly 5 in it, it can be known that the driving shaft 51 is installed on the bearing inside the working box 1. While the motor 2 drives the driving shaft 51 to rotate through the reversing plate 53, the design that the reversing plate 53 is eccentrically installed on the side surface of the driving shaft 51 can also enable it to drive the pressing plate 55 to swing reciprocally through the guide rod 54, so that the infusion bottles inside the working box 1 surge towards the outer periphery of the connector 522. However, it should be noted that the top of the pressing plate 55 is always higher than the highest water level line, which makes the infusion bottles not be clamped between the pressing plate 55 and the inner wall of the working box 1, so that the device can work more smoothly;

[0057] During the process of the driving shaft 51 driving the sorter 52 to rotate, the mouth of the infusion bottle will be stuck in the notch of the connector 522. And because the infusion bottle is made of plastic material, the infusion bottle will not be stuck too firmly in the notch of the connector 522. This makes that if the infusion bottle stuck in the notch is in a flipped state, the baffle 11 blocks the infusion bottle from rising further and presses the infusion bottle to fall until the mouth is stuck in the notch. After that, the connector 522 drives the mouth of the infusion bottle to rise first. And the bottle body and the mouth are designed with an arc surface. After being pressed by the baffle 11, the mouth can be better stuck in the notch, so as to insert the infusion bottle onto the reciprocating threaded rod 62. Further, the working efficiency and smoothness of the device are improved;

[0058] The sorting plates 56 are respectively located on both sides of each metal ring 521, so that when the squeezing plate 55 continues to stir the water inside the working box 1, the infusion bottle will be located between every two adjacent sorting plates 56 after being impacted by the water flow, and the bottom or bottle cap of the infusion bottle will always face the docking connector 522. Since the active shaft 51 will drive the metal ring 521 and the docking connector 522 to rotate continuously, when the bottom of the bottle faces the docking connector 522, the rotating docking connector 522 will hit the bottom of the bottle and flip the infusion bottle, thereby making the bottle cap face the docking connector 522 and get stuck in the groove on the docking connector 522, further improving the working stability of the device.

[0059] like Figure 1 , Figure 4 and Figure 5 As shown, the adapter assembly 4 includes a metal box 41 fixed to the side of the working box 1 and a bevel gear 1 42 transmission connected to the outer side of the reversing plate 53, the internal bearing of the metal box 41 is installed with a secondary shaft 44, the upper and lower ends of the secondary shaft 44 are respectively transmission connected with a bevel gear 2 43, the internal bearing of the metal box 41 is installed with a bevel gear 3 45, the end of the bevel gear 3 45 is transmission connected with a gear 1 47, and the outer periphery of the gear 1 47 is transmission connected with each gear 2 63 through a chain 46.

[0060] The lower end bevel gear 2 43 meshes with the bevel gear 1 42 , and the upper end bevel gear 2 43 meshes with the bevel gear 3 45 .

[0061] The above scheme is adopted: the reversing plate 53 moves through the inner wall of the working box 1, so that the motor 2 can drive the bevel gear 1 42 to rotate through the driving shaft 51 and the reversing plate 53, and the bevel gear 1 42 drives the bevel gear 3 45 to rotate through the bevel gear 2 43 and the secondary shaft 44, and the bevel gear 3 45 drives each gear 2 63 to rotate through the gear 1 47 and the chain 46, further, so that each cleaning component 6 can work more smoothly.

[0062] like Figure 1 , Figure 3 , Figure 5 and Figure 8 As shown, the fishing assembly 3 includes a central axis 31 with a bearing installed inside the working box 1, the output shaft of the motor 2 is connected to the central axis 31 through a belt 15, and the outer periphery of the central axis 31 is hinged with a plurality of arc plates 32 at equiangular angles in an annular direction, and each arc plate 32 is elastically connected to the outer periphery of the central axis 31 through a spring sheet 33, and a retention plate 12 is fixed inside the working box 1, and the end of the retention plate 12 is located between two of the arc plates 32.

[0063] Adopting the above solution: when the infusion bottle is divided, a part of the aluminum foil used for sealing it may fall off. Although the density of the aluminum foil is greater than that of water, the aluminum foil will not sink rapidly. Therefore, during the process of the central shaft 31 driving the arc-shaped plate 32 to rotate, the aluminum foil will be fished. When the arc-shaped plate 32 touches the end of the retention plate 12, the aluminum foil on it will fall and be located between the retention plate 12 and the working box 1. Further, the time and energy for subsequent manual collection of the aluminum foil are reduced.

[0064] The working principle and usage process of the present invention:

[0065] First, disinfectant and cleaning agent are infused into the working box 1, and the recycled infusion bottles are placed on one side of the internal partition of the working box 1. The internal part of the working box 1 is divided into a sorting component 5 and a fishing component 3 by the partition, and the water level inside the working box 1 shall not exceed the height of the partition;

[0066] While the motor 2 drives the main shaft 51 to rotate through the reversing plate 53, the design that the reversing plate 53 is eccentrically installed on the side of the main shaft 51 can also enable it to drive the pressing plate 55 to swing reciprocally through the guiding rod 54. The infusion bottles inside the working box 1 surge towards the outer periphery of the docking device 522, and the bottle mouth of the infusion bottle is stuck in the slot of the docking device 522, and then the infusion bottle is inserted onto the reciprocating threaded rod 62;

[0067] The bevel gear one 42 drives the bevel gear three 45 to rotate through the bevel gear two 43 and the secondary shaft 44. The bevel gear three 45 drives each bevel gear two 63 to rotate through the gear one 47 and the chain 46. During the process of the bevel gear two 63 driving the reciprocating threaded rod 62 to rotate, the limiter 65 moves reciprocally. When the hook 653 passes over the bottle mouth, it will quickly return to the initial position. Due to the shape of the hook 653 and the elasticity of the spring piece two 652, its bottom will be embedded in the plastic bottle mouth and drive the plastic bottle mouth to move. The tapered design at the end of the reciprocating threaded rod 62 can also enable it to easily pierce the bottom of the infusion bottle, and the blade 68 will also divide a complete infusion bottle into several pieces. Moreover, as the reciprocating threaded rod 62 continues to rotate, the water pumped by the water pump 13 and infused into the reciprocating threaded rod 62 through the transfer box 14 can be sprayed onto the inner wall of the infusion bottle from all directions through the water tank for cleaning;

[0068] After the cleaning is completed, the distance between each limiting plate 67 becomes larger, and the inclined end of the hook 653 is guided by the guiding plate 66, and the hook 653 is no longer engaged with the infusion bottle. The water pressure sprayed by the water tank can make each piece of plastic separate from the cleaning component 6;

[0069] The central shaft 31 drives the arc-shaped plate 32 to rotate to fish the aluminum foil. When the arc-shaped plate 32 touches the end of the retention plate 12, the aluminum foil on it will fall and be located between the retention plate 12 and the working box 1.
