Description

Technical field:

[0001] The invention relates to the field of medical decontamination equipment, in particular to a decontamination device. Background technology:

[0002] At present, some medical devices at home and abroad, such as endoscopes, surgical instruments, dental instruments, etc., cannot be sterilized at high temperatures and high pressures due to their own characteristics and material problems. However, due to the high prices of these medical devices in clinical practice, it is impossible to use them once, and these medical devices must be cleaned and disinfected, and then reused. At present, there are two main ways to disinfect endoscopes: manual disinfection and disinfection by fully automatic disinfection machines. The main disinfection steps are: cleaning - washing - rinsing - disinfection - final rinsing. Manual endoscope cleaning and disinfection mostly use the "five-step method" or "four-step method" of a five-slot or four-slot endoscope manual disinfection line. By implementing different cleaning steps of the endoscope in different sinks, the cleaning of the endoscope surface by the manual disinfection line is limited to soaking in water, cleaning solution, and disinfectant; the fully automatic endoscope disinfection machine can automatically perform the steps in sequence in the same sink. The disinfection step, but the fully automatic endoscope disinfection machine is also limited to two cleaning methods for the surface of the endoscope: immersion and spraying with water, cleaning liquid, and disinfectant. It is easy for biological tissues and secretions to remain on the surface of the endoscope, and cleaning liquid residues and disinfectant residues will lead to infection control risks of disinfection failure, and may threaten the health of patients and medical staff; and if the biological tissues and secretions attached to the surface of the endoscope are not cleaned, they are very easy to solidify into crystals during the disinfection process, which is difficult to clean, and it is very easy to cause cross infection of patients, and it will also affect the service life of the endoscope.

Specific implementation method:

[0026] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] The embodiments of the present invention are as follows Figure 1-10 As shown, in a first embodiment, a disinfection device includes a shell 1, a concave cavity in the shell 1 constitutes a disinfection space, a plurality of wave devices are provided on the inner wall of the shell 1, the outer end of each wave device extends out of the shell 1 and is connected to a driving device, and each wave device is sealed and connected to the shell 1 at the connection through a sealing component, a drain pipe 2 connecting the inside and outside of the shell 1 is provided at the bottom of the shell 1, and a first solenoid valve 3 is provided on the drain pipe 2; a plurality of disinfection basket assemblies for placing utensils to be disinfected are provided in the shell 1; a top cover 5 is movably buckled on the top of the shell.

[0028] like Figure 8 As shown, the wave device is a vertically arranged impeller 6, the connecting shaft of the impeller 6 horizontally passes through the shell 1 and is connected to the driving device; a plurality of stirring ribs 31 are evenly arranged along the circumference of the inner end face of the impeller 6, and a chamfered inclined surface 37 is respectively arranged on both sides of the front end face of each stirring rib 31.

[0029] The driving device includes a plurality of driving motors 4, and the output shafts of the driving motors 4 are respectively connected to the connecting shafts of the impellers 6 at their corresponding positions. Of course, in order to reduce the number of driving motors 4, only one driving motor can be provided, which is driven by a belt transmission mechanism or a gear transmission mechanism to drive the two impellers 6 to rotate.

[0030] In this embodiment, the first solenoid valve 3 and the drive motor 4 are both connected to an external power supply, and the first solenoid valve 3 and the drive motor 4 are provided with corresponding control switches, wherein the control switch of the drive motor 4 can also control the rotation speed of the drive motor 4. The drive motor 4 in this embodiment is preferably a direct-drive brushless drive motor. This part is an existing technical means commonly used by technicians in this field and will not be described in detail here.

[0031] In this embodiment, the wave device is a impeller 6, and five stirring ribs 31 are evenly arranged along the circumference of the inner end surface of the impeller 6. A chamfered slope 37 is provided on both sides of the front end surface of each stirring rib 31, and the outer end between the slope and the stirring rib 31 is 60 degrees, thereby enabling the wave device to have a stronger stirring effect on the liquid. Of course, the wave device can also be in other forms, such as a stirring rod, impeller, etc., which can produce different stirring effects. In addition, in order to achieve a better stirring effect on the liquid in the shell 1, in the present embodiment, two relatively arranged impellers 6 are provided, which are respectively arranged on two opposite side walls in the shell 1, and the two impellers rotate in the same direction, thereby enabling the two impellers 6 to have a stronger and more uniform stirring ability when rotating. In order to enable the impellers to fully stir the liquid in the shell, the rotating axes of the two impellers 6 may not be in the same straight line, for example, one high and one low, one left and one right; of course, in order to simplify the structure, only one impeller 6 may be arranged on any side wall in the shell 1; or, in order to further enhance the stirring effect, multiple impellers 6 may be arranged on the same side wall of the shell 1. Furthermore, impellers 6 may be arranged on adjacent side walls in the shell 1 at the same time to produce different stirring effects.

[0032] Therefore, when the outer surface of the endoscope is to be disinfected, the endoscope can be placed in the disinfection basket assembly, and the disinfection basket assembly can be placed in the concave cavity of the shell 1, so as to prevent the endoscope from being entangled with the wave device and the endoscopes from being entangled with each other. Moreover, when the wave device rotates, the top cover 5 can effectively prevent liquid from splashing, which is beneficial to keeping the disinfection room clean and preventing liquid from splashing onto the operator.

[0033] The decontamination basket assembly includes a first basket 7, and a second basket 8 is movably engaged with the top of the first basket 7 through a buckle 9. A fixed storage space for the decontamination equipment to be decontaminated is formed between the first basket 7 and the second basket 8. A plurality of holes for water flow are provided on the first basket 7 and the second basket 8. Thus, it is convenient to place the endoscope in the decontamination basket assembly, and the holes on the first basket 7 and the second basket 8 can facilitate the fluctuation of the liquid inside the decontamination basket assembly, which is conducive to the liquid impacting the surface of the endoscope, and can also timely flush the biological tissue and secretions washed off the endoscope from the inside of the decontamination basket assembly. In this embodiment, the first basket 7 and the second basket 8 are both hollowed-out baskets, and a buckle 9 is respectively provided on the top of the two opposite side walls of the first basket 7, and a hollow portion is respectively provided on the side wall of the second basket 8 corresponding to each buckle 9. When in use, the second basket 8 is buckled on the first basket 7, and each buckle 9 is respectively engaged in the hollow portion at the corresponding position. Of course, the first basket 7 and the second basket 8 can also be movably connected through other structures. For example, one end of the first basket 7 and the second basket 8 can be movably connected through a rotating shaft and the other end can be connected through a pin.

[0034] On one of the inner side walls of the shell 1, there are provided a plurality of first chutes 10 for fixing the washing and disinfection basket assembly. Either end of the washing and disinfection basket assembly is movably inserted into the first chutes 10, and the two side walls of the first chutes 10 are respectively in contact with the second basket 8 and the first basket 7 at the corresponding positions. Thus, the first chutes 10 can limit the movement of the washing and disinfection basket assembly, and can effectively prevent the washing and disinfection basket assembly from touching the wave device when moving in the shell 1. In this embodiment, there are two first chutes 10 in total, and the washing and disinfection basket assembly is vertically inserted into each chute. One of the side walls of the first chutes 10 is in contact with the first basket 7, and the other is in contact with the second basket 8. Thus, when the wave device rotates, the washing and disinfection basket assembly is placed vertically, and the liquid in the shell 1 can fully impact the endoscope in the washing and disinfection basket assembly, which has a better wave disinfection effect. Of course, in actual use, in order to lower the height of the shell 1 and reduce the amount of disinfectant, only one first chute 10 can be provided, and the disinfection basket assembly is placed flat in the first chute 10, and the two side walls of the first chute 10 respectively and simultaneously abut against the two sides of the disinfection basket assembly.

[0035] A second chute 11 cooperating with each first chute 10 is provided on the inner side wall of the housing 1 on the opposite side of each first chute 10. This can more stably limit the position of the disinfection basket assembly in the housing 1 and more effectively prevent the disinfection basket assembly from moving.

[0036] It should be noted that, in the present embodiment, the first slide groove 10 and the second slide groove 11 are formed by two oppositely arranged baffles on the inner wall of the shell 1 and the shell 1, thereby reducing the thickness of the shell 1 while ensuring the strength of the shell 1. Of course, the first slide groove 10 and the second slide groove 11 can also be formed by directly slotting on the inner wall of the shell 1.

[0037] A plurality of weighted barrels 12 are provided on one side of the housing 1, and each weighted barrel 12 can be slidably inserted in the first chute 10, and each weighted barrel 12 is provided with a flow hole for water to flow through. Therefore, when only one endoscope is to be decontaminated, the weighted barrel 12 can be filled with clean water, and the weighted barrel 12 can be placed in one of the chute, thereby reducing the amount of water used for decontamination, and in different decontamination steps, when the decontamination basket assembly needs to be placed in different housings 1, the weighted barrel 12 can be moved together, reducing the amount of decontamination liquid. In addition, since the weighted barrel 12 is provided with a flow hole 13 for water to flow through, the influence of the weighted barrel 12 on liquid fluctuations can be effectively reduced. In this embodiment, two flow holes 13 are provided in the middle of the counterweight barrel 12 for liquid to pass through. Of course, in actual use, in order to simplify the structure of the counterweight barrel 12, a notch can also be provided on both sides of the bottom of the counterweight barrel 12. When the counterweight barrel 12 is placed in the shell 1, the gap between the counterweight barrel 12 and the shell 1 can allow liquid to pass through.

[0038] In order to timely clean the biological tissues and body fluids washed off the surface of the endoscope from the housing 1, and further reduce the possibility of biological tissues and body fluids remaining on the surface of the endoscope and the washing basket assembly, a circulation pipe 14 connecting the inside and outside of the housing 1 is provided at the bottom of any inner side wall of the housing 1, and a second solenoid valve 15 is provided on the circulation pipe 14. The outer end of the circulation pipe 14 is connected to the water inlet of a filter 16, and the water outlet of the filter 16 is connected to a circulation pump 17 through a water pipe. A plurality of nozzles 18 are provided on the upper section of any inner side wall of the housing 1, and the spray pipes 19 corresponding to each nozzle 18 are respectively sealed and penetrate the side wall of the housing 1 and are connected to the water outlet of the circulation pump 17, and each spray pipe 19 is respectively provided with a one-way valve 20. The circulation pump 17 is connected to the external power supply through a wire, and the circulation pump 17 is provided with a corresponding switch. The filter 16 can preferably use a CGQ series strong magnetic pipeline filter. Therefore, the circulation pump 17 and the second solenoid valve 15 can be opened during the disinfection process, and the liquid in the shell 1 enters the filter 16 through the circulation pipe 14 for filtration. The filtered water is pressurized by the circulation pump 17 and then sprayed into the shell 1 through the nozzle 18. This can not only filter the liquid, but the nozzle 18 can also further enhance the impact force of the liquid in the shell 1 by spraying liquid, thereby improving the disinfection effect.

[0039] When the decontamination device of the present invention is used in a manual cleaning multi-slot assembly line, a total of five decontamination devices are provided, which are respectively used for cleaning, detergent washing, rinsing, disinfection, and final rinsing. When decontaminating an endoscope, the endoscope is first placed in the first basket 7, the second basket 8 is buckled on the first basket 7, the second basket 8 and the first basket 7 are buckled together by the buckle 9, the decontamination basket assembly is placed in the first chute 10, and then the counterweight bucket 12 is placed in another first chute, clean water is first injected into the inner side of the shell 1, the top cover 5 is buckled, and then the switch of the driving motor 4 is turned on. The drive motor 4 is controlled to rotate, thereby driving the impeller 6 to stir the clean water in the shell 1, so that the clean water continuously impacts the surface of the endoscope. At the same time, the circulation pump 17 and the second solenoid valve 15 are opened to filter the liquid in the shell. After the cleaning of the endoscope surface is completed, the water in the shell 1 is discharged by opening the first solenoid valve 3 switch; when the endoscope surface is washed, rinsed, disinfected, and finally rinsed with a detergent, the disinfection basket assembly with the endoscope is placed in the corresponding shell 1, and the corresponding liquid is injected. During the disinfection process, the impeller 6 rotates to complete the corresponding disinfection steps.

[0040] In this embodiment, the manual cleaning multi-tank assembly line includes five disinfection devices of the present invention, and each disinfection device is used for cleaning, detergent washing, rinsing, disinfection, and final rinsing. It should be noted that this embodiment is only an example of the application of the disinfection device of the present invention on the manual cleaning multi-tank assembly line. The disinfection steps, the number and functions of the disinfection devices in this embodiment are not limitations on the specific implementation of the present invention.

[0041] The second embodiment of the present invention is as follows Figure 9-10 As shown, it is a further improvement made on the basis of the first embodiment, specifically a fully automatic disinfection device. Compared with the disinfection device in the first embodiment, in this embodiment, a plurality of cavity perfusion joints 21 are provided on the upper section of any side wall of the shell 1, and the access pipes 36 of each cavity perfusion joint 21 are respectively sealed and pass through the side wall of the shell 1 and are connected with the liquid outlet end of a liquid inlet main pipe 22. A liquid inlet pipe 23 is provided on any inner side wall of the shell 1, and the outer end of the liquid inlet pipe 23 is sealed and passes through the side wall of the shell 1 and is connected with the liquid outlet end of the liquid inlet main pipe 22, and a third solenoid valve 24 is provided on the liquid inlet pipe 23; the water inlet end of the liquid inlet main pipe 22 is respectively connected with the water outlets of a plurality of liquid supply pumps through a multi-way pipe; a one-way valve 20 is respectively provided at the water outlet of each liquid supply pump; and a leak detection joint 29 is respectively provided on one side of each cavity perfusion joint 21. A leak detection tube is connected to each leak detection joint 29, and the outer end of each leak detection tube is sealed and extends out of the side wall of the housing 1. When leak detection is performed, an air pump or an electric pump can be connected to the outer end of the leak detection tube for leak detection.

[0042] In the present embodiment, there are two cavity perfusion joints 21 and two leak detection joints 29, which correspond to the two first chutes 10 respectively. When the number of the first chutes 10 changes, the number of the cavity perfusion joints 21 and the leak detection joints 29 changes accordingly. In addition, in the present embodiment, the liquid inlet main pipe 22 is connected to three liquid supply pumps through a four-way pipe 25. The three liquid supply pumps are a clean water pump 26, a disinfection pump 27, and a washing pump 28. In actual use, the number and type of liquid supply pumps can be selected according to demand. When only one liquid supply pump is provided, the disinfection device of the present invention can only perform a single disinfection step, such as cleaning or disinfection. Therefore, multiple devices of the present invention can be used to form a complete disinfection production line, and the staff only needs to manually transfer the disinfection basket assembly.

[0043] In this embodiment, since the liquid outlet end of the liquid inlet main pipe 22 is connected to each cavity perfusion joint 21 and the liquid inlet pipe 23 at the same time, when the decontamination liquid is injected into the housing 1, it can be injected from the outside of the endoscope and the endoscope cavity at the same time, and the surface and the inner cavity of the endoscope can be decontaminated at the same time, which reduces the workload of the staff to manually decontaminate the inner cavity of the endoscope. In addition, since a third electromagnetic valve 24 is provided on the liquid inlet pipe 23, when the liquid in the housing 1 is injected to a certain height, the liquid inlet pipe 23 can be closed by the third electromagnetic valve 24, and only the cavity perfusion joints 21 continue to inject liquid to flush the inner cavity of the endoscope, thereby improving the decontamination effect of the inner cavity of the endoscope and saving decontamination liquid. In addition, the water inlet end of the liquid inlet main pipe 22 is connected to the outer end of the endoscope cavity. The four-way pipe 25 is respectively connected with the water outlet of a clean water pump 26, the water outlet of a disinfection pump 27, and the water outlet of a washing pump 28. A one-way valve 20 is respectively provided at the water outlet of the clean water pump 26, the water outlet of the disinfection pump 27, and the water outlet of the washing pump 28. Therefore, when performing different disinfection steps, the liquid in the shell 1 can be discharged first, and then the disinfection liquid is injected into the concave cavity of the shell 1 through the corresponding pump. Multiple disinfection steps can be completed in one shell 1, which can reduce the workload of the staff, reduce the number of shells 1 and other components, and save space. The one-way valve 20 at the water outlet of each liquid supply pump can also prevent the disinfection liquid from flowing back, effectively avoiding the disinfection liquid from flowing into other pumps and preventing the disinfection liquid from mixing.

[0044] It should be noted that, in the present embodiment, the water inlet of the clean water pump 26 is connected to a container for storing clean water or a clean water pipeline, the water inlet of the disinfection pump 27 is connected to a container for storing disinfectant or a disinfectant pipeline, the water inlet of the washing pump 28 is connected to a container for storing washing liquid or a washing liquid pipeline, the third solenoid valve 24 and each liquid supply pump are connected to an external power supply through a wire and are provided with a corresponding switch, and the liquid outlet end of the liquid inlet main pipe 22 is simultaneously connected to each cavity perfusion joint 21 and the liquid inlet pipe 23 through a multi-way connector.

[0045] A liquid level sensor 30 is provided on the outer side of the bottom of the shell 1. The liquid level sensor 30, the first solenoid valve 3, the second solenoid valve 15, the third solenoid valve 24, the circulation pump 17, the clean water pump 26, the disinfection pump 27, the washing pump 28, and each driving motor 4 are electrically connected to the external universal control device through wires.

[0046] Thus, the decontamination device of the present invention can be fully automatically operated. The liquid level height in the housing 1 is monitored in real time by the liquid level sensor 30. Therefore, when the clean water pump 26 is running to inject clean water into the housing 1, when the liquid level in the housing 1 is higher than the height of the circulation pipe 14, the control device opens the second solenoid valve 15 and the circulation pump 17 to start filtering the liquid in the housing 1, and the water flow sprayed by the nozzle 18 can be directly sprayed to the endoscope in the decontamination basket assembly to wash the surface of the endoscope, which has a good decontamination effect; when the liquid level in the housing 1 reaches a preset value, the control device controls the third solenoid valve 24 to close, the liquid inlet pipe 23 to stop inletting liquid, and only the cavity perfusion joints 21 continue to inject liquid, and at the same time controls the drive motor 4 to start rotating to clean the surface of the endoscope; and, since the cavity perfusion joints 21 continuously inject decontamination liquid into the housing 1, the liquid level in the housing 1 will continue to increase. When the height in the housing 1 reaches the set warning height, the control device can also control the first solenoid valve 3 to open and discharge part of the liquid to effectively prevent the liquid in the housing 1 from overflowing. After the clean water cleaning is completed, enter the next disinfection step. The specific disinfection process is the same as the clean water cleaning process.

[0047] It should be noted that in this embodiment, the liquid level sensor 30 is an ultrasonic liquid level sensor, which can be arranged outside the housing 1 to avoid the influence of the liquid level sensor 30 on the decontamination effect. In actual use, other forms of liquid level sensors 30 can also be used, such as float liquid level sensors; the control device includes a central processing unit, a display screen, and control buttons. In this embodiment, the control device operates each pump and each solenoid valve according to the liquid level height monitored by the liquid level sensor 30, which is a prior art means.

[0048] The top of each side wall of the shell 1 extends outward from the shell 1 to form a support plate 32. An L-shaped step 33 is provided on the top of each side wall of the shell 1. The four sides of the cover plate are movably buckled on the steps at the corresponding positions. An overflow hole 34 is provided on any support plate 32. The upper end of a leakage pipe 35 is sealed and connected to the overflow port. In this way, when the liquid level in the shell 1 is too high, the liquid in the shell 1 can be discharged from the L-shaped step 33 through the overflow hole 34, avoiding the liquid from flowing out of the top of the shell 1 at will, and effectively preventing the cleaning liquid from polluting the entire working space.

[0049] When in use, the decontamination device in this embodiment is used as a fully automatic decontamination device. Specifically, the endoscope to be decontaminated is first connected to the leak detection connector 29 through a special connector for leak detection. After the leak detection is completed, the endoscope is placed in the decontamination basket assembly, and the decontamination basket assembly is placed in the slide slot. The endoscope is connected to the cavity irrigation connector 21 through the endoscope special connector, the top cover 5 is buckled, and the decontamination device is started by the control device. First, the cleaning operation is performed. The clean water pump 26 is turned to inject clean water into the liquid inlet main pipe 22. When the liquid level in the shell 1 is higher than the height of the circulation pipe 14, the control device opens the second solenoid valve 15 and the circulation pump 17, and starts to filter the liquid in the shell 1. In addition, the water flow sprayed by the nozzle 18 can be directly sprayed to the endoscope in the decontamination basket assembly to rinse the surface of the endoscope, which has a good decontamination effect. When the liquid level in the shell 1 reaches the preset value, The control device controls the third solenoid valve 24 to close, the liquid inlet pipe 23 stops inletting liquid, and only the perfusion joints 21 of each cavity continue to inject liquid, and at the same time controls the drive motor 4 to start rotating to clean the surface of the endoscope; and the liquid level in the shell 1 will continue to increase.
