Detailed Description

Example 1: the embodiment provides a cleaning system, which mainly aims at the centralized and classified cleaning treatment of ultrasonic probes which are responsible for a supply and guarantee center (or similar functional departments) of medical institutions such as hospitals and the like.

As described above, the ultrasound probes collected and processed by the supply and security center come from different departments and are used for different patients, and a part of the probes are common external probes which do not need to be disinfected deeply, such as physical examination probes, and some probes are external, but the probes need to be disinfected deeply for infectious diseases of skin surfaces of patients, and some probes are used in interventional therapy, so that the pollution degree is high, the infection risk is high, and the probes need to be cleaned and disinfected strictly according to standards. At present, the mature scheme of efficient batch and classified cleaning of the ultrasonic probes aiming at different pollution conditions is not well carried out on the market. In addition, in some cases, even the same ultrasound probe may change the cleaning and disinfecting criteria depending on the subsequent therapeutic use changes.

Based on the above needs, the staff of the medical institution may manually clean different ultrasonic probes according to the use condition identification information of the ultrasonic probes, and may also perform uniform deep disinfection cleaning on all the ultrasonic probes, where the former working mode is time-consuming and laborious, and the latter working mode not only increases the operation time and the consumption of disinfectant, but also increases the potential risk of damage of the ultrasonic probes, and the probability of glutaraldehyde disinfectant residue used for deep disinfection may be increased, and clinical indication shows that some patients' bodies have adverse reactions on glutaraldehyde residues.

The chain type step cleaning equipment is a cleaning equipment with large treatment capacity and easy automatic operation, has no application precedent in the cleaning treatment of an ultrasonic probe, is used for simply modifying the existing cleaning working line, can be used for liberating the labor intensity of workers in a supply and guarantee center, is not flexible in application when the general chain type step cleaning equipment is used for treating ultrasonic probes with different pollution degrees or is used for treating different ultrasonic probes to different sanitary standards (colony indexes), cannot meet the requirements of treatment capacity and efficiency, for example, is used for treating a low-pollution probe with larger treatment capacity and does not need aldehyde killing flushing, and is time-consuming and unnecessary if the low-pollution probe is also queued on a flushing line.

The overall working principle of the solution provided by the embodiment is shown in fig. 1, and the embodiment realizes centralized and classified collection and efficient and high-quality cleaning treatment of the ultrasonic probe by providing a cleaning system comprising a classified collection device and a step cleaning device. In the treatment process, after simple pretreatment, different ultrasonic probes are classified into general cleaning and deep cleaning by using one cleaning line, and finally, the ultrasonic probes are collected and packaged.

Specifically, in conjunction with fig. 2, 5 and 6, the cleaning system of the present embodiment includes a sort collection device 10 as shown in fig. 2 and a step cleaning device 20 as shown in fig. 5 and 6.

The sorting and collecting apparatus 10 should generally comprise a sorting and collecting container 11, and in this embodiment the sorting and collecting apparatus 10 comprises a sorting and collecting container 11 and a collecting vehicle 12, a plurality of sorting and collecting containers 11 being loaded on the collecting vehicle 12, each sorting and collecting container 11 having a plurality of separate receiving chambers 111.

The classifying and collecting device 10 is the basis of the work of the utility model, and ultrasonic probes used by different departments/departments are concentrated, classified and marked by the classifying and collecting device 10 for subsequent cleaning treatment. The manner of marking can be various, but in order to strictly ensure safe use and transportation and to prevent mixed use risks, the soft package auxiliary marking is carried out on each ultrasonic probe, and the soft package auxiliary marking is that the soft package auxiliary marking adopts a soft package (a disposable plastic packaging bag) with different marks (colors, marks, labels and the like) to contain each ultrasonic probe and then is placed into the accommodating cavity 111 of the classified collection container 11, so that the disposable soft package not only reduces the risk of pollution of the classified collection container 11, but also plays the role of the classified marking, and of course, the use of the soft package cannot replace the disinfection treatment of the classified collection container 11.

As shown in fig. 5 and 6, the step-by-step cleaning apparatus 20 includes a cleaning table 21 and a conveyor chain 22, wherein the cleaning table 21 has a plurality of cleaning stations, the conveyor chain 22 adopts a general circulating conveyor belt structure (existing structure, not shown in the drawings) and has a conveying surface 221, and as shown in the drawing, a loading grate plate 23 is mounted on the conveying surface 221, and the loading grate plate 23 can at least accommodate the ultrasonic probe of the cleaning object of the present utility model, and of course, from the technical proposal of the present application, the cleaning apparatus can also be extended for cleaning other similar medical components.

One loading grate plate 23 should accommodate only one ultrasonic probe, which is sized to accommodate all or most of the ultrasonic probes currently used in each department/department that require frequent cleaning, preferably circular in shape, and the operator can easily place the ultrasonic probes or coiled probes and connecting wires into the loading grate plate 23.

The chain belt of the conveyor chain 22 itself is of a spaced-apart structure, and the charging grate plate 23 is also hollow, so as to allow water flow through at a subsequent flushing and cleaning station.

As further shown in fig. 5, the conveyor chain 22 is a unitary conveyor chain, but its conveying surface 221 is divided in the width direction into a first conveying zone i and a second conveying zone ii, each of which is fitted with at least one row of loading grate plates 23, and accordingly, the cleaning station 21 is divided in the width direction into a general cleaning zone and a deep cleaning zone, each of which includes a cleaning rinse station a and a sanitizing rinse station, and the deep cleaning zone has a sanitizing rinse station different from the general cleaning zone. Thus, during the cyclic operation of the conveyor chain 22, the loading grate plate 23 mounted on the first conveyor section I can be stepped through the various stations of the general cleaning section, and the loading grate plate 23 mounted on the second conveyor section II can be stepped through the various stations of the deep cleaning section. The stepwise advancing direction of the conveyor chain 22 is indicated with black arrow symbols in fig. 5.

Further, as shown in fig. 6, each of the stations of the above-mentioned general cleaning zone and deep cleaning zone has unsealed through-holes which are adjacent to each other to function as mutual support, and the conveyor chain 22 entirely passes through the through-holes in the middle of these holes.

Specifically, as shown in fig. 6 (a), the cavities of the three stations of the general cleaning area are connected from side to side, and as can be seen from fig. 5, the three cavities are also connected to the front and rear of the three cavities of the rear deep cleaning area, the front side panels of the cavities of the three stations of the general cleaning area can be provided with transparent panels, so that an operator can observe the cleaning operation condition inside the cleaning area in front, and a middle partition plate can be arranged between the cavities of the adjacent stations to reduce the risk of sputtering of the flushing liquid across the stations, but the middle partition plate is transparent at least in the central part to allow the conveying chain 22 and the loading grate 23 loaded with the ultrasonic probe to pass through without obstruction.

As shown in fig. 6 (b), the cavities of five stations of the deep cleaning area are connected left and right, and as can be seen from fig. 5, the three cavities on the right side are also connected front and back to the three cavities of the general cleaning area in front, the front of the two cavities on the left side can be in an open structure, so that the conveying chain 22 can pass through, and the middle partition plates can be arranged between the cavities of the adjacent stations and can be penetrated at the central part.

An important innovation of the embodiment is that the main liquid medium cleaning procedure in the cleaning operation is unified into a flushing procedure (few probes are subjected to enzyme leaching treatment in advance), and flowing liquid is sprayed under pressure during flushing, so that the cleaning and disinfecting components can be fully circulated and flow, and the cleaning and disinfecting components can be quickly contacted with the surfaces of the probes, so that the cleaning and disinfecting efficiency is better than that of static soaking.

Further, the cleaning stations of the general cleaning zone and the deep cleaning zone of the present embodiment are designed in conjunction with the process flow shown in fig. 3 and 4 after optimizing and standardizing the operation standard in the cleaning operation. Thus, in this embodiment, the foregoing general cleaning zone disinfection and rinse station includes an alcohol disinfection and rinse station B, the deep cleaning zone disinfection and rinse station includes an alcohol disinfection and rinse station B and an aldehyde disinfection and rinse station located before the alcohol disinfection and rinse station B, and the general cleaning zone disinfection and rinse station and the deep cleaning zone disinfection and rinse station are followed by an irradiation treatment station C, and ultraviolet irradiation and drying after the irradiation treatment station C completes the rinse cleaning.

The cleaning and flushing station a in this embodiment has cleaning and flushing nozzles 211, preferably, the cleaning and flushing nozzles 211 are arranged at the upper and lower sides, the used flushing liquid is pure water, and the water flow can pass through the gaps of the charging grate plate 23 and the conveying chain 22 and then is directly discharged into the waste water pipeline below the cavity, so that the waste water pipeline is not recycled.

In order to conserve water resources, when the clean rinse time has reached the minimum rinse time required by the process but has not reached the overall stepping cycle time set uniformly by the conveyor chain 22, the water valve or power pump to that station may be temporarily shut down to halt the rinse, which may be automated by programmed timing.

The alcohol sterilization rinse station B in this embodiment has an alcohol sterilization rinse nozzle 212, and preferably, the alcohol sterilization rinse nozzle 212 is disposed above and below, the rinse liquid used is a high-concentration ethanol solution with a volume concentration of 50% or more, such as a 75% ethanol solution, and alcohol sterilization rinse is strictly performed on two types of ultrasonic probes in the alcohol sterilization rinse station B, so as to meet the minimum sterilization time requirement. Unlike the cleaning and flushing station a, the flushing liquid stream of the alcohol killing and flushing station B is discharged into a liquid storage tank for recycling after passing through the gaps of the charging grate plate 23 and the conveying chain 22.

Since the aldehyde killing rinse step in deep cleaning is usually not less than 25 minutes, and typically more than 30 minutes, according to the operation guidance requirements and the sanitary standard after cleaning, a more important solution in the present utility model is to decompose the aldehyde killing rinse process in deep cleaning into a primary aldehyde killing rinse process and a secondary aldehyde killing rinse process as illustrated in fig. 4, and the aldehyde killing rinse stations shown in fig. 5 and 6 also include a primary aldehyde killing rinse station D1 and a secondary aldehyde killing rinse station D2. In the stepping process of the conveying chain 22, the preset residence time of the ultrasonic probe at each station is the same, and after the aldehyde killing washing step which takes longer time for decomposition, the uniformly arranged stepping residence time is not obviously overlong because the aldehyde killing washing time standard is obviously higher than the other step time standard.

The primary aldehyde killing and flushing station D1 and the secondary aldehyde killing and flushing station D2 in this embodiment are respectively provided with a primary aldehyde killing and flushing nozzle 214 and a secondary aldehyde killing and flushing nozzle 215, and each stage of nozzle is also preferably arranged at two positions up and down, the flushing liquid used is glutaraldehyde solution, and the volume concentration is not lower than 1.8%, and is generally about 2.0%.

And the aldehyde killing flushing station strictly executes aldehyde killing flushing on the ultrasonic probe needing deep cleaning, so that the minimum killing time requirement is met. The flushing liquid flow of the aldehyde killing flushing station B is discharged into a liquid storage tank for circulating and extracting after passing through the gaps of the charging grate plate 23 and the conveying chain 22. If the accumulated aldehydic rinse time criteria has been reached in advance at the secondary aldehydic rinse station D2 during a stepped dwell time period of the conveyor chain 22, the circulating power pump of that station can be automatically turned off by programming, but since the rinse liquid of that station is recycled, there is generally no waste of sterilizing liquid, it is also possible to eliminate the need to set an automatic shut-down program for the circulating power pump to subject the ultrasonic probe to aldehydic rinse continuously throughout the dwell period of the aldehydic rinse station B. Preferably, the system sets a selection program for the user to select among automatic shut-down programs of whether to turn on the circulation power pump through the operation interface.

The irradiation treatment station C in this embodiment at least includes the ultraviolet irradiation lamp 213, the ultraviolet irradiation treatment time is short, and a good sterilization effect can be achieved in about 5 minutes, and the long time is unfavorable for protecting sensitive components such as the ultrasonic probe and the connecting wire, so that the ultraviolet irradiation lamp 213 should be turned on intermittently or in a delayed manner in one step residence time period of the conveying chain 22, instead of being turned on in the whole step residence time period. The ultrasonic probe is preferably dried at the irradiation treatment station C with the aid of a normal heat source (a resistive heat source or a lamplight heat source), the cavity temperature at the time of drying is higher than room temperature but not more than 45℃, and the ultraviolet irradiation lamp 213 is preferably turned on after a period of time from the start of drying of the ultrasonic probe or after completion of drying of the ultrasonic probe.

In this embodiment, as an optimal design, in order to reasonably install the irradiation treatment apparatus, the irradiation treatment space is optimally arranged, the irradiation treatment stations C common to the general cleaning area and the deep cleaning area are aligned at least as shown in fig. 5, and more preferably, as shown in fig. 7, the irradiation treatment stations C common to the general cleaning area and the deep cleaning area are made into an integral module, that is: the same irradiation treatment equipment is compatible with a front station and a rear station.

Similarly, in order to facilitate the construction of the cleaning table 21 and the connection and arrangement of the flushing pipes, the alcohol-killing flushing stations B shared by the general cleaning area and the deep cleaning area are also aligned at least as shown in fig. 5, and it is also preferable to make the alcohol-killing flushing stations B of the general cleaning area and the alcohol-killing flushing stations B of the deep cleaning area as an integral module as shown in fig. 7, and the same circulating liquid supply system can be used for the alcohol-killing flushing heads 212 of the two stations in addition to the cavity structure itself.

Example 2: the present embodiment provides a cleaning method based on the cleaning system provided in embodiment 1, including the steps of:

s1, ultrasonic probes with different pollution degrees are classified and collected by using a classification and collection container 11 of the classification and collection device 10. As described above, in order to strictly ensure safe use and transportation and to prevent mixed use risk, each ultrasonic probe is flexibly packaged for auxiliary identification, and a disposable flexible package with different identifications (color, sign, label, etc.) is used to hold each ultrasonic probe and then placed into the accommodating cavity 111 of the classified collection container 11, so that the risk of pollution of the classified collection container 11 is reduced and the classified identification function is also achieved.

S2, a cleaning staff determines whether the cleaning mode of the ultrasonic probe is general cleaning or deep cleaning according to the collected classification information, and the ultrasonic probe which needs to be preprocessed is preprocessed before different ultrasonic probes are placed on the conveying chain 22 of the step cleaning device 20. Depending on the specific use of the ultrasound probe, the pretreatment may include couplant erasure and/or enzymatic leaching, which is a prior cleaning treatment for an ultrasound probe, for example for in vivo or interventional therapy.

S3, placing an ultrasonic probe which needs to be subjected to general cleaning on the charging grate plate 23 of the first conveying area I of the conveying surface 221, placing an ultrasonic probe which needs to be subjected to deep cleaning on the charging grate plate 23 of the second conveying area II of the conveying surface 221, enabling the ultrasonic probe which needs to be subjected to general cleaning to step through a cleaning flushing station A, an alcohol killing flushing station B and an irradiation treatment station C of the general cleaning area, performing corresponding cleaning flushing, alcohol killing flushing and irradiation treatment, enabling the ultrasonic probe which needs to be subjected to deep cleaning to step through the cleaning flushing station A, the primary aldehyde killing flushing station D1, the secondary aldehyde killing flushing station D2, the alcohol killing flushing station B and the irradiation treatment station C of the deep cleaning area, and performing corresponding cleaning flushing, multistage aldehyde killing flushing, alcohol killing flushing and irradiation treatment.

In this step, the residence time of the ultrasound probe at each station can be extended to 10-25min, preferably controlled to 15-20min as described in example 1. As described above, the residence time of the ultrasonic probe at each station does not necessarily represent the processing time at each station, because the processing time at each station may be controlled by a program and there are cases of time-out, delay or intermittent operation, which are described in embodiment 1 and will not be repeated.

And S4, collecting, information marking and packaging the ultrasonic probe which is subjected to the general cleaning and the deep cleaning.

In this step, the information mark of the ultrasonic probe which completes cleaning should at least contain the probe type, attribution or coding information, the cleaning state and cleaning standard information corresponding to the probe, the information of the probe type, attribution or coding information and the like can be further matched with a packaging container, the packaging container is preferably a rigid sanitary container, and the packaging container can be placed in the accommodating cavity 111 of the classified collecting container 11, transported by the collecting vehicle 12 and distributed to various departments/departments for use.

Since the use of the flexible package cannot replace the sterilization process of the sorting collection container 11, the cleaning of the sorting collection container 11 should also be completed before the cleaned and packaged ultrasonic probe is again collected using the sorting collection container 11, and preferably during the implementation of step S2 or S3 of the present embodiment, the sorting collection container 11 is cleaned, preferably the sorting collection container 11 is a stainless steel container, and can be sterilized at a high temperature of 100 ℃ or higher.

Example 3: this embodiment provides a cleaning line for an ultrasonic probe based on the cleaning system provided in embodiment 1, as shown in fig. 8, comprising a pretreatment station E, a collection and packaging station F, and an optional container treatment station G in addition to the partial modules of the cleaning system described in embodiment 1.

Wherein the pretreatment station E is disposed before the loading station of the step cleaning apparatus 20 described above, for performing couplant wiping and/or enzyme-immersed treatment of the ultrasonic probe, a stainless steel operation table with an enzyme-immersed treatment tank may be used.

The collecting and packaging station F is used for collecting, information marking and packaging the ultrasonic probe which completes general cleaning and deep cleaning, and a common intermediate operation table can be used. Wherein, after the ultrasonic probe on the charging grate plate 23 leaves the irradiation treatment station C after the irradiation is finished, in order to avoid collision and confusion of the probe during unloading, manual unloading can be adopted, and the probe can be directly collected, information marked and packaged during manual unloading. In order to reduce the operation burden of the operator, the operator may be prompted to collect and subsequently process the ultrasonic probes by means of photoelectric recognition and signal alarm when the ultrasonic probes leaving the irradiation treatment station C accumulate to a certain number or are about to be conveyed to the turning position of the conveyor chain 22.

The container treatment station G is used for high-temperature sterilization of the sorting containers 11, and the sterilizing cabinet used may be heated by means of heating pipes or steam.

The pretreatment of the ultrasonic probe, the collection packaging of the ultrasonic probe after cleaning, and the treatment of the classification collection container 11 are also described in detail in embodiment 2, and will not be described again.

As can be seen from fig. 8, the pretreatment station E, the step cleaning apparatus 20 of the cleaning system, the collection and packaging station F, and the container treatment station G (and also the seating station of the sorting and collecting apparatus 10) can be connected end to end and form a closed loop in the operation room, thereby greatly improving the compactness of the production line and the space utilization in the operation room.

It can be seen from the above embodiments that, according to the cleaning system, the cleaning method and the cleaning line for an ultrasonic probe provided by the present utility model, the classifying and collecting device 10 and the step cleaning device 20 are adopted, so that the ultrasonic probes with different pollution levels are classified and collected by using the classifying and collecting device 10, and the cleaning mode of the ultrasonic probe is determined according to the collecting and classifying information, so that the cleaning operation of the ultrasonic probes with different pollution levels or different cleaning standard requirements by using one cleaning flushing line is realized on the basis of optimizing the cleaning processing mode and improving the cleaning processing capacity by means of the multi-mode cleaning process of the step cleaning device 20, and the cleaning effect is further ensured by optimizing the process and the station connection, and the cleaning efficiency is improved.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the scope of the present utility model are intended to be included in the scope of the present utility model.
