Description

Technical Field

[0001] The present invention relates to the field of disinfection devices, and particularly to a cleaning and disinfection device for medicine baskets in a pharmacy intravenous admixture service (PIVAS). Background Art

[0002] In the operation system of a pharmacy intravenous admixture service (PIVAS) in a medical institution, the medicine basket is the core carrier for holding infusion bottles, vials, and liquid preparation utensils. The quality of its cleaning and disinfection is directly related to the microbial safety and chemical residue control of intravenous medications. However, there is a fundamental contradiction between the structural characteristics of existing medicine baskets and disinfection technologies: Medicine baskets generally adopt a high-density grid design (mesh density 3 - 5 holes / cm 2 ), forming a crisscross grid structure inside. Although this design facilitates liquid penetration and draining, during repeated use, residues of high-risk drugs such as cytotoxic drugs and antibiotics form stubborn attachments in areas such as the mesh intersections and grid intersections. Traditional spray disinfection devices cover the surface of the medicine basket with high-pressure water flow or chemical spray at a fixed angle. However, due to the limitations of fluid dynamics, the penetration rate of the disinfection medium into the deep pores of the medicine basket is less than 40%. Especially when multiple medicine baskets are stacked for use, the physical limitation of the surface spacing between adjacent surfaces being less than 2 cm further exacerbates the spray blind spots. Research shows that the clearance rate of such disinfection devices for organic residues (such as proteins and fat-soluble drugs) on the inner wall of the medicine basket only reaches 65 - 78%, which is significantly different from the 99% sterility standard required by the PIVAS, creating a potential risk of cross-infection.

[0003] The single-mode nature of existing disinfection devices further magnifies the technical defects. Mainstream devices rely on static spraying or high-pressure flushing in a single direction, and their disinfection paths are limited by the fixed angle of the nozzles and the fluid turbulence effect. When the medicine baskets are in a stacked state, the spraying medium is difficult to effectively penetrate into the sandwich area, resulting in hidden areas such as grid intersections and bottom support bars becoming disinfection dead zones. Although some disinfection devices introduce a rotating basket cleaning mechanism, which drives the movement of the medicine basket through axial rotation, its movement trajectory only changes the macroscopic position of the medicine basket and fails to break through the fluid dynamics limitations inside the mesh holes. Biofilms are still easily formed at the grid intersections (such as the residual rate of Pseudomonas aeruginosa biofilm being as high as 34%).

[0004] Overall, the existing medicine basket disinfection technology faces twofold challenges: Firstly, the design of the disinfection device does not fully consider the physical characteristics of the grid structure of the medicine basket, resulting in insufficient contact between the disinfection medium and the contaminated surface; Secondly, the disinfection mode lacks adaptability to complex geometries, and static treatment and single-direction cleaning are difficult to cover all contaminated interfaces. The superimposed effect of the above defects causes residues inside the medicine basket after multiple uses to be further embedded in the material surface through mechanical wear or chemical corrosion, forming a stubborn contamination layer that is difficult to remove. This technical bottleneck not only threatens the safety of intravenous medications but also may lead to the risk of microbial drug resistance due to incomplete disinfection, highlighting the urgency of developing a new type of cleaning and disinfection device. Summary of the Invention

[0005] The present invention aims to provide a cleaning and disinfection device for medicine baskets in a intravenous admixture center, which solves the problem of incomplete disinfection existing in the existing cleaning and disinfection devices.

[0006] To achieve the above objective, the technical solution of the present invention is as follows: A cleaning and disinfection device for medicine baskets in a intravenous admixture center, comprising:

[0007] A disinfection cylinder;

[0008] A cover body, which covers the opening of the disinfection cylinder;

[0009] An electric push rod, which is arranged at the center of the bottom inside the disinfection cylinder;

[0010] A lifting plate, which is arranged at the free end of the electric push rod;

[0011] A first one-way valve, which is installed on the lifting plate, enabling the disinfectant liquid to move from below the lifting plate to above the lifting plate through the first one-way valve;

[0012] A flexible pad, which is connected between the lifting plate and the inner wall of the disinfection cylinder. The flexible pad and the lifting plate divide the disinfection cylinder into an upper cavity and a lower cavity;

[0013] A second one-way valve, which is installed on the flexible pad. The second one-way valve can enable the disinfectant liquid on the flexible pad to flow into the lower cavity through the second one-way valve;

[0014] A medicine basket limiting mechanism, which is arranged in the upper cavity and is used to limit the position of the medicine basket.

[0015] Furthermore, a partition plate is provided in the lower cavity. A through hole for the electric push rod to pass through is opened on the partition plate, and the electric push rod is slidably and sealingly connected to the through hole.

[0016] With the above settings, the space enclosed by the partition plate, the lifting plate and the flexible pad is used to store the disinfectant solution, which is convenient for reducing the usage amount of the disinfectant solution, thereby controlling the cleaning and disinfection cost of the medicine basket.

[0017] Furthermore, a ring-shaped water collecting pad is provided on the partition plate. The inner diameter of the water collecting pad is slightly larger than the diameter of the lifting plate, and the height of the water collecting pad gradually decreases from the side close to the inner wall of the disinfection cylinder towards the center.

[0018] With the above settings, the water collecting pad facilitates the collection of the disinfectant solution inside the water collecting pad (i.e., directly below the lifting plate), thereby improving the flow efficiency of the disinfectant solution and facilitating the pressurized ejection of the disinfectant solution to enhance the cleaning and disinfection effect on the medicine basket.

[0019] Furthermore, a ring-shaped slag collecting groove is provided on the water collecting pad. The slag collecting groove is closer to the center of the disinfection cylinder than the second one-way valve. A slag discharging hole penetrating through the water collecting pad and the inner wall of the disinfection cylinder is provided on the slag collecting groove, and a sealing plug is plugged at the slag discharging hole.

[0020] With the above settings, during the continuous circulation of the disinfectant solution, the slag collecting groove can intercept the impurities in the disinfectant solution, avoiding the situation that the impurities enter the medicine basket again with the disinfectant solution, resulting in incomplete cleaning and disinfection of the medicine basket.

[0021] Furthermore, a push plate located below the partition plate is fixedly connected to the push rod of the electric push rod. The push plate is slidably and sealingly connected to the lower cavity. A hose is communicated between the push plate and the partition plate, and a third one-way valve is provided on the hose. A fourth one-way valve communicating with the outside is installed on the lower side of the lower cavity.

[0022] With the above settings, by means of the lifting of the push plate, the volume change of the lower cavity below the push plate is changed, thereby improving the flow rate of the disinfectant solution above the partition plate by exhausting air. And the gas will generate bubbles after passing through the one-way valve, and the continuously emerging bubbles will burst when they reach the disinfectant solution surface or contact with the medicine basket, thereby enhancing the cleaning effect on the medicine basket.

[0023] Furthermore, electric heating tubes are installed on the bottom of the cover body and the upper surface of the lifting plate.

[0024] With the above settings, the electric heating tubes can quickly dry the medicine basket, thereby effectively keeping the medicine basket dry.

[0025] Furthermore, a liquid discharge pipe is provided on the partition plate. One end of the liquid discharge pipe passes through the side wall of the disinfection cylinder, and a control valve is provided on the liquid discharge pipe.

[0026] With the above settings, the control valve and the liquid discharge pipe can quickly discharge the waste liquid after disinfection, which is beneficial to the continuous use of this disinfection device.

[0027] Further, the medicine basket limiting mechanism includes a plurality of L-shaped limiting hooks, each of which is rotatably connected to the upper cavity. A torsion spring is connected between the limiting hook and the inner wall of the disinfection cylinder. When the flexible pad is flush with the lifting plate, the lowest part of the limiting hook is close to the flexible pad and the flexible pad is not deformed.

[0028] Further, when the bottoms of the plurality of limiting hooks are flush, the torsional forces of the plurality of torsion springs are different when they are twisted by the same angle.

[0029] Through the above settings, by means of the different acting forces generated during the contact between the medicine basket and the plurality of limiting hooks, the posture of the medicine basket can be adjusted differently, so as to thoroughly clean the medicine basket.

[0030] Further, a protective sleeve is provided at the end of the limiting hook.

[0031] Through the above settings, by means of the protective sleeve, the impact force on the medicine basket can be reduced when the limiting hook contacts the medicine basket, avoiding the situation of the medicine basket being damaged.

[0032] Compared with the prior art, the beneficial effects of this solution are as follows:

[0033] 1. Through the dynamic cyclic intermittent impact structure of the disinfectant solution, the present invention makes the disinfectant solution form a jet flow with a certain pressure and cooperate with the circumferential eddy current, significantly enhancing the penetration ability of the disinfectant solution into the high-density grid structure of the medicine basket, effectively removing stubborn residues in hidden areas such as the mesh hole angle and grid intersection, and solving the deep pollution problem existing in traditional spray disinfection.

[0034] 2. The present invention adopts a disinfectant solution guiding structure composed of a flexible pad and a water collecting pad, forming a directional circulation during the lifting process, so that the disinfectant solution generates a continuous flushing effect between the stacked sandwich layers of the medicine basket, completely solving the problem of insufficient penetration of the spray medium caused by the stacking of medicine baskets in traditional equipment, and avoiding areas such as grid intersections becoming disinfection dead corners.

[0035] 3. The medicine basket limiting mechanism of the present invention has a variable torque design, enabling the medicine basket to automatically adjust its posture according to the fluid acting force during the disinfection process, forming a dynamic angle change, ensuring that the disinfection medium is in full contact with the inner wall of the medicine basket, breaking through the limitations of traditional fixed or single-direction disinfection modes, and significantly improving the disinfection uniformity of complex geometric surfaces.

[0044] Embodiment

[0045] As Figures 1 to 6 shown, a cleaning and disinfection device for medicine baskets in a static drug dispensing center includes:

[0046] Disinfection cylinder 1, the disinfection cylinder 1 has an opening only at the top, and a through hole for installing the electric push rod 5 is opened at the center of the bottom of the disinfection cylinder 1.

[0047] Cover body 2, the cover body 2 covers the opening of the disinfection cylinder 1. In this embodiment, electric heating tubes 3 are installed on the bottom of the cover body 2 and the upper surface of the lifting plate 6, and a controller 4 electrically connected to the electric push rod 5 and the electric heating tube 3 is installed on the upper surface of the cover body 2. The controller 4 can control the opening or closing of the electric push rod 5 and the electric heating tube 3.

[0048] Electric push rod 5, the electric push rod 5 is arranged at the through hole at the center of the inner bottom of the disinfection cylinder 1, and the bottom of the electric push rod 5 is not lower than the bottom of the through hole. In this embodiment, a push plate 18 located below the partition plate 13 is fixedly connected to the push rod of the electric push rod 5. The push plate 18 is slidably and sealingly connected to the lower cavity. A hose 19 is communicated between the push plate 18 and the partition plate 13. A third one-way valve 20 is provided on the hose 19. An air inlet pipe 21 is communicated with the side wall of the lower cavity, and a fourth one-way valve 22 located outside the disinfection cylinder 1 is installed on the air inlet pipe 21.

[0049] The lifting plate 6 is welded to the top of the electric push rod 5. A plurality of liquid outlet holes 7 are formed in the lifting plate 6 outside the upper push rod of the electric push rod 5.

[0050] The first one-way valve 8 is installed at the liquid outlet hole 7, so that the disinfectant can move from below the lifting plate 6 to above the lifting plate 6 through the liquid outlet hole 7 and the first one-way valve 8.

[0051] The flexible pad 9 is provided with a connection hole in the middle having the same size as the lifting plate 6. The inner wall of the connection hole of the flexible pad 9 is fixedly connected between the side wall of the lifting plate 6 and the inner wall of the disinfection cylinder 1. The disinfection cylinder 1 can be divided into an upper cavity and a lower cavity by the flexible pad 9 and the lifting plate 6. In this embodiment, a plurality of circulation holes 10 are circumferentially formed on one side of the flexible pad 9 close to the inner wall of the disinfection cylinder 1. A circulation pipe 11 is inserted into each circulation hole 10.

[0052] A partition plate 13 is adhered in the lower cavity. A through hole for the electric push rod 5 to pass through is formed in the partition plate 13. The electric push rod 5 is slidably and sealingly connected with the through hole in the partition plate 13. An annular water collecting pad 14 is adhered to the partition plate 13. The inner diameter of the water collecting pad 14 is slightly larger than the diameter of the lifting plate 6. The height of the water collecting pad 14 gradually decreases from the side close to the inner wall of the disinfection cylinder 1 to the center of the disinfection cylinder 1. An annular slag collecting groove 15 is formed in the water collecting pad 14. The slag collecting groove 15 is closer to the center of the disinfection cylinder 1 than the second one-way valve 12. A slag discharging hole 16 penetrating through the side wall of the water collecting pad 14 and the inner wall of the disinfection cylinder 1 is formed in the slag collecting groove 15. A sealing plug 17 is plugged at the slag discharging hole 16. By opening the sealing plug 17, the impurities in the slag collecting groove 15 can be discharged by means of discharging waste water or injecting clean water. A liquid discharging pipe 23 with one end located outside the disinfection cylinder 1 is communicated with the bottom of the partition plate 13. One end of the liquid discharging pipe 23 penetrates through the side wall of the disinfection cylinder 1. A control valve 24 is arranged on the liquid discharging pipe 23, and the disinfected waste liquid can be quickly discharged through the control valve 24.

[0053] The second one-way valve 12 is installed on the circulation pipe 11. The second one-way valve 12 can enable the disinfectant on the flexible pad 9 to flow into the upper part of the partition plate 13 through the circulation pipe 11 and the second one-way valve 12.

[0054] Medicine basket limiting mechanism, the medicine basket limiting mechanism is arranged in the upper cavity, and the medicine basket limiting mechanism is used to limit the position of the medicine basket. In this embodiment, the medicine basket limiting mechanism includes four concave-shaped fixing blocks 25. A rotating shaft 26 is rotatably connected to the opening of each fixing block 25. An L-shaped limiting hook 27 is provided on each rotating shaft 26. A protective sleeve 29 is provided at the free end of the limiting hook 27, and the protective sleeve 29 will not react with the disinfectant. The lowest part of the limiting hook 27 is located above the flexible pad 9. A torsion spring 28 is connected between the rotating shaft 26 and the inner wall of the fixing block 25. When the flexible pad 9 is flush with the lifting plate 6, the lowest part of the limiting hook 27 is close to the flexible pad 9, and the flexible pad 9 is not deformed. When the bottoms of the four limiting hooks 27 are flush, the torsion forces of the four torsion springs 28 are different when they are twisted by the same angle.

[0055] The working process of this embodiment is as follows:

[0056] The first working mode: Put the medicine basket into the disinfection cylinder 1. In this working mode, when the size of the medicine basket is larger than the area range initially enclosed by the adjacent ends of the four limiting hooks 27, directly place the medicine basket on the four limiting hooks 27. At this time, the inner wall of the medicine basket abuts against the protective sleeves 29 on the four limiting hooks 27 and does not contact the flexible pad 9.

[0057] After the medicine basket is placed, inject disinfectant into the disinfection cylinder 1 by opening the cover body 2. The amount of disinfectant needs to submerge half of the height of the medicine basket when the lifting plate 6 and the flexible pad 9 are on the same plane. During cleaning and disinfection, the controller 4 controls the electric push rod 5 to drive the lifting plate 6 to reciprocate up and down within a certain range. During the upward movement of the lifting plate 6, the lifting plate 6 drives the flexible pad 9 to move upward, and the flexible pad 9 drives the four limiting hooks 27 and the medicine basket to move upward. At this time, the flexible pad 9 bulges upward through its own deformation, so that the disinfectant on the flexible pad 9 enters the space between the flexible pad 9 and the partition plate 13 through the circulation holes 10, the circulation pipe 11 and the second one-way valve 12. At the same time, since the electric push rod 5 drives the push plate 18 to move upward, the space below the push plate 18 increases, so that the outside air is sucked into this space through the air inlet pipe 21 and the fourth one-way valve 22, realizing the air suction operation.

[0058] When the electric push rod 5 drives the flexible pad 9 to move downward through the lifting plate 6, the flexible pad 9 will gradually change from bulging upward to being flush with the lifting plate 6, and finally achieve a concave shape change, making the space between the flexible pad 9 and the water collecting pad 14 smaller. The disinfectant liquid in the space will be quickly sprayed towards the medicine basket through the liquid outlet hole 7 and the first one-way valve 8, thereby enhancing the cleaning and disinfection effect on the medicine basket. At the same time, since the push plate 18 moves downward, the volume of the space below the push plate 18 shrinks, so that the air in this space enters the space between the partition plate 13 and the lifting plate 6 through the hose 19 and the third one-way valve 20, accelerating the ejection of the disinfectant liquid from the liquid outlet hole 7. And because bubbles will be generated after the air passes through the liquid outlet hole 7, the bubbles will quickly rise in the disinfectant liquid. The bubbles will burst after contacting the medicine basket or the liquid surface of the disinfectant liquid, and the impact force generated by the bursting of the bubbles will continuously clean the medicine basket deeply, which is beneficial to achieving deep cleaning and disinfection of the medicine basket. For stacked medicine baskets, the impact force generated by the bursting of the bubbles is also beneficial to improving the cleaning effect inside the stack.

[0059] In this method, through the thrust generated during the circulation of the disinfectant liquid, as well as the different supporting forces provided by the limit hooks 27 and the torsion springs 28, the angle of the medicine basket can be continuously changed, which is beneficial to achieving deep and comprehensive cleaning of the medicine basket. During the circulation of the disinfectant liquid, the disinfectant liquid will carry the cleaned impurities to the slag collecting tank 15 and deposit them at the bottom of the slag collecting tank 15. Finally, after the cleaning and disinfection are completed, the impurity in the slag collecting tank 15 can be discharged together when the disinfected waste liquid is drained by unplugging the sealing plug 17. In order to improve the efficiency of waste liquid discharge and achieve rapid internal cleaning, the control valve 24 can be opened to drain the liquid pipe 23, so that the waste liquid, clean water, and impurities can be quickly discharged from the slag discharge hole 16 and the drain pipe 23.

[0060] The second working method: The difference between this working method and the first working method is only that: in this working method, when the size of the medicine basket is smaller than the range initially enclosed by the adjacent ends of the four limit hooks 27, the medicine basket can be abutted between the adjacent side walls of the four limit hooks 27, and the medicine basket is placed on the flexible pad 9. During the process of the flexible pad 9 and the lifting plate 6 driving the medicine basket to move up and down, the attitude of the medicine basket will also be changed due to the different forces exerted on the medicine basket by the four limit hooks 27. At this time, the degree of deformation of the flexible pad 9 will also vary greatly in different regions. The circulating flow process of the disinfectant liquid and the inhalation and exhaust path of the air are the same as those in the first working method.

[0061] The above are only embodiments of the present invention, and common knowledge such as specific structures and / or characteristics known in the solution is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
