Description

Alarm system and method for manual cleaning and perfusion of soft endoscope

Technical Field

The invention relates to the technical field of medical auxiliary instruments, in particular to an alarm system and method for manually cleaning perfusion of a soft endoscope.

Background

According to the WS 507 and 2016 soft endoscope cleaning and disinfection technical specification, the soft endoscope manual cleaning step comprises the steps of bedside pretreatment, side leakage, manual cleaning, rinsing, disinfection, final rinsing and drying. The three steps of rinsing, disinfecting and final rinsing all relate to a perfusion procedure of 3 minutes or 5 minutes, if perfusion faults occur, cleaning workers do not find the perfusion faults in time, the endoscope cleaned manually cannot reach the cleaning and disinfecting standard, and cross infection is easily caused after the endoscope is reused.

According to statistics, most domestic endoscope centers adopt two concurrent modes of manual cleaning and endoscope cleaning and sterilizing machines to carry out disinfection and sterilization treatment on soft endoscopes at present. Investigation also shows that during the manual cleaning process, once perfusion is failed, endoscope clearance is not up to the standard. For partial perfusion faults, such as perfusion pipeline cutoff, washing and disinfecting workers can find the faults through visual observation, but the manual monitoring is easy to generate an inattentive phenomenon, and no related alarm device is used for reminding; for perfusion faults which are difficult to find visually, such as the cutoff of an enzyme adding pipeline and a dilution pipeline, cleaning liquid can not reach the standard and does not meet the clearing standard, so that the clearing is incomplete; during the clearing process of the workers, the appearance of the perfusion faults is not limited to the cutoff of the perfusion pipeline, and various perfusion faults which may occur cannot be monitored in real time.

Because of the above problems in practice and the advent of products that do not solve these problems, there is a need for improvement.

The designation of the design orientation merely indicates the relative positional relationship between the respective members, not the absolute positional relationship.

The first embodiment is as follows:

according to a first aspect of the present invention, there is provided a flow chart of an alarm method for manually cleaning perfusion of a soft endoscope, as shown in fig. 1, comprising:

step S101: the interfaces of the perfusion pipelines are connected with the cavity interfaces one by one, and perfusion is started manually by workers to enter a perfusion state.

In the embodiment of the invention, the endoscope can comprise an insertion end and an exposed end, wherein the insertion end is used for being inserted into a corresponding position in a patient body and is of a long catheter structure; the exposed end is used for connecting related equipment and is provided with a plurality of inner cavities. Expose the end and contain a plurality of inner chambers, alone carry out the perfusion to the interface of a chamber way, the perfusate can only fill and can't circulate in a plurality of chamber ways, reach not reaching the washing, the effect and the standard of killing, consequently, carry out the washing of scope, when killing, can be simultaneously to the perfusion that carries out of every inner chamber, only keep an export of the long pipe of scope, the perfusate does not flow out from the chamber way of inner chamber, when the perfusate enters from every inner chamber, can wash away the chamber way, the bulk velocity of flow of perfusate is great, can play good killing effect.

Specifically, the perfusion equipment can be provided with a plurality of pools that kill, and the perfusion pipeline in every pond that kills includes a trunk line at least, and the trunk line can be said according to each chamber on the scope and is provided with a plurality of branch pipes, and the tip of branch pipe sets up the inner joint, and each chamber is said and is set up the external tapping, and the inner joint can form unified cooperation relation with the external tapping that corresponds for the position that the chamber was said is different, but the interface cooperation structure is the same, all can connect, has the universality. The inner diameters of the branched pipes for shunting can be set according to the corresponding cavity channels, and the branched pipes are in one-to-one correspondence.

Before the perfusion operation of the endoscope, all the channel interfaces of the endoscope need to be connected with a perfusion pipeline, so that the internal cavity is cleaned and sterilized in all directions, and omission is avoided. The perfusion operation can be started by manual operation of workers, and meanwhile, a shutdown button is arranged.

In the embodiment of the invention, the starting of perfusion in the current killing pool specifically comprises the following steps:

connecting the inner interfaces of the branch pipes with the outer interfaces of the corresponding cavity channels in a one-to-one correspondence manner, so that the perfusion liquid in the branch pipes can enter the corresponding cavity channels; the branch pipe is connected with the cavity, and perfusion liquid can directly enter the cavity, and filling, washing, sterilizing and the like of the perfusion liquid are carried out on the corresponding cavity.

The perfusion liquid in each cavity channel can only be converged to flow to a long catheter of the endoscope and is discharged out of the endoscope, so that the internal structure which is internally connected is cleaned and sterilized in all directions; it can be understood that each cavity is connected with the branch pipe, and only the port of the long conduit of the endoscope is reserved as the water outlet, so that the perfusion liquid in each cavity can be gradually converged, flows to the long conduit of the endoscope and is discharged from the port of the long conduit of the endoscope. The inner chambers of the endoscopes are filled with flowable perfusion liquid, so that all-around cleaning and disinfection can be realized, and the cleaning and disinfection of the endoscopes are ensured to meet the standard.

After the connection of the perfusion pipeline and the endoscope is finished, placing the endoscope in a disinfection tank, controlling the perfusion start of the disinfection tank by a worker, perfusing the endoscope, and enabling the disinfection tank to enter a perfusion state; it can be understood that after the connection of the perfusion pipeline and the endoscope is completed, the endoscope can be completely placed in the disinfection tank to prepare for perfusion operation, the current perfusion starting of the disinfection tank can be carried out by a worker, the endoscope in the current disinfection tank is perfused, and the current disinfection tank enters a perfusion state.

In the embodiment of the invention, the starting/stopping button can be arranged aiming at each sterilizing pool to form independent control of the perfusion state in the sterilizing pools, and the sterilizing pools do not mutually influence. When the start button is pressed, the current killing pool enters a perfusion state, and perfusion operation can be executed; after the perfusion operation is finished, automatically ending the perfusion state, entering a standby state and waiting for starting; when the stop button is pressed, the current killing pool enters a temporary stop state, and the perfusion operation is stopped. It is understood that after the perfusion state is automatically ended, the worker may clean the current killing tank.

In the embodiment of the invention, as the required content of the perfusion liquid is large and the storage is troublesome, the effective substances can be concentrated into the mother liquid for storage, and when the perfusion liquid is used, the mother liquid is diluted by the diluent and is mixed according to different requirements in proportion, so that a large amount of required perfusion liquid is quickly formed.

Therefore, before entering into the perfusion state, still should carry out the mother liquor self-checking, detect whether the mother liquor content of current perfusion equipment is sufficient, avoid influencing the perfusion, mother liquor self-checking specifically includes:

predefining a lower limit liquid level, marking the lower limit position of the lowest stock of the mother liquid in the mother liquid storage tank, and if the lower limit position is lower than the lower limit position, directly perfusing is not recommended and the mother liquid should be filled first.

Predefining an upper limit liquid level, marking the upper limit position of the stock of the mother liquid in the mother liquid storage tank, and limiting the filling of the full stock of the mother liquid.

if the initial liquid level is higher than the lower limit liquid level, starting operation of a worker is waited, and the perfusion state is directly entered; the stock of the mother liquor is sufficient, the request of the disinfection pool for entering the perfusion state can be responded, and when a worker presses a start button, the disinfection pool can directly enter the perfusion state.

If the initial liquid level is lower than the lower limit liquid level, an enzyme adding warning is directly sent out, and an enzyme adding operation can be carried out by a worker; if the stock of the mother liquor is not enough, the mother liquor should be added first. Can send out and add enzyme warning, the suggestion staff is current not enough in mother liquor content, can add the enzyme operation by the staff.

Detecting the current liquid level of the mother liquor in the enzyme adding operation process, and sending an enzyme full prompt to prompt a worker that the enzyme adding is finished when the current liquid level is detected to reach the upper limit liquid level; it can be understood that in the process of enzyme adding operation, the stock of the mother liquor is increased, when the liquid level in the mother liquor storage tank reaches the upper limit liquid level, the mother liquor can be considered to be full, and an enzyme full prompt can be sent to prompt a worker to stop adding the enzyme.

It will be appreciated that the type of response to the enzyme addition alert and the enzyme full prompt may include a voice announcement, and flashing lights.

In the embodiment of the invention, the total consumption of the perfusion liquid required by one-time sterilization can be estimated according to the total number of the sterilization tanks and the consumption of the single-time sterilization perfusion, the total consumption of the perfusion liquid required by one-time sterilization is completed under the condition that all the sterilization tanks perform perfusion, the proportion of the mother liquid required by the perfusion liquid of the total consumption is calculated according to the total consumption in proportion, and the lower limit liquid level is set according to the proportion.

Step S102: obtaining the residual amount of the current perfusion liquid, outputting a recommended clearing amount according to an endoscope in the killing pool, sending out a current shortage warning when detecting that the recommended clearing amount is smaller than the lower limit value of the residual amount, entering an automatic liquid adding state, and responding to the request of entering the perfusion state of the next killing pool after completing automatic liquid adding.

In the embodiment of the invention, the perfusion liquid is prestored in the perfusion tank, after the perfusion is started, the perfusion liquid in the perfusion tank is continuously consumed, and when the residual quantity of the perfusion liquid in the perfusion tank is insufficient, a current shortage warning is sent to indicate that the current residual quantity of the perfusion liquid is insufficient, which can affect the subsequent perfusion, so that the perfusion liquid needs to be filled and the residual quantity of the perfusion liquid in the perfusion tank needs to be replenished.

In an embodiment of the present invention, the perfusion fluid filling specifically includes:

pre-defining a standard perfusion value; the standard perfusion value is the consumption of perfusion liquid when the endoscope perfusion is completed in a disinfection tank.

After the perfusion pipelines perfuse each cavity of the endoscope, detecting the residual amount of the current perfusion liquid, and calculating the recommended clearing amount of the residual amount according to the standard perfusion value so as to help the staff to estimate the clearing amount of the endoscope; and calculating the surplus of the perfusion liquid and the number value multiplied by the standard perfusion value, and rounding, wherein the rounded value can be used as the recommended clearing amount to represent the number of times of endoscope perfusion which can be carried out, and the evaluation of the follow-up workload by workers is facilitated.

Determining a lower limit value according to the using number of the killing pools in the perfusion state, and judging whether the recommended clearing amount is less than the lower limit value:

if the recommended clearing amount is not less than the lower limit value, normal perfusion in each current disinfection pool is continued; the residual amount of the perfusion liquid is enough at present, and perfusion can be continued.

If the recommended clearing amount is smaller than the lower limit value, sending a current shortage warning to remind a worker that the residual amount of the perfusion liquid is insufficient, and automatically entering a liquid adding state; the residual amount of the perfusion liquid is insufficient at present, and the perfusion liquid needs to be filled. Can send out the warning of short-flow to the staff, the surplus of perfusion liquid is not enough, gets into automatic liquid feeding state.

In the embodiment of the invention, the lower limit value can be determined according to the using number of the killing pools which enter the perfusion state, and the lower limit value is slightly larger than the using number of the killing pools, so that the residual amount of the perfusion liquid can complete the current perfusion of the current killing pools in the perfusion state.

In the embodiment of the present invention, the liquid adding state specifically includes:

s11: the request of the next killing pool entering the perfusion state is not responded, and the perfusion operation of the current killing pool in the perfusion state is continuously executed;

s13: conveying the perfusion liquid into a perfusion liquid tank, detecting the residual amount of the perfusion liquid in the perfusion liquid tank, calculating recommended clearing amount, and judging whether the recommended clearing amount is larger than the upper limit value of the residual amount;

in the embodiment of the invention, when the perfusion tank enters the liquid adding state, in order to prevent the excessive consumption of the residual perfusion liquid and influence the cleaning and killing of the endoscope, the response to the request of the next killing tank for entering the perfusion state can be suspended, but the perfusion operation of the killing tank which has already entered the perfusion state is kept to be continuously executed, and the perfusion is not influenced.

In the embodiment of the invention, after the liquid adding state is entered, because the stock of the perfusion liquid tank is large, half-bin filling of the primary mixing bin cannot fill the perfusion liquid tank, and meanwhile, each killing pool entering the perfusion state still continuously consumes the perfusion liquid, in the filling process, an upper limit value can be set as a comparison standard, the allowance in the perfusion liquid tank after single filling is detected in real time, the recommended clearing amount is calculated, and when the recommended clearing amount is smaller than the upper limit value, half-bin filling of the primary mixing bin is performed again; and when the recommended clearing amount is larger than the upper limit value, stopping filling, and judging that filling is finished.

It can be understood that, half storehouse mixes, and the stirring dynamics can set up great, is favorable to fast, all with mix, forms the perfusion liquid.

In the embodiment of the invention, after filling is completed, the request of the next killing pool for entering the perfusion state can be responded again.

It can be understood that the upper limit value can be formulated according to the total number of the killing pools, and the upper limit value can be a multiple of the total number of the killing pools so as to meet the actual perfusion requirement of the endoscope center; the lack of flow warning comprises flashing of an indicator light and voice broadcasting.

In an embodiment of the present invention, after entering the liquid adding state, the step S12 specifically includes:

and predefining a theoretical proportion, namely the theoretical proportion of the mother liquor and the diluent, and mixing the mother liquor and the diluent according to the theoretical proportion to form the perfusion fluid.

Predefining an error range; an allowable error range is set to limit an error between the injection amount of the mother liquid and the injection amount of the diluent within the allowable range.

Detecting the mother liquor flow in the mother liquor pipeline in unit time, and detecting the dilution flow in the dilution pipeline in unit time; and acquiring the flow in the mother liquor pipeline and the flow in the dilution pipeline in unit time, wherein the flow is related to the inner diameter of the pipeline and the flowing speed of liquid.

if the error range is within, directly and uniformly mixing; the proportion is proper, and the uniform mixing can be directly carried out.

If the error value does not belong to the error range, calculating a compensation amount according to the error value, and uniformly mixing after compensation; when the proportion is not suitable, a large shortage exists in one party, and the compensation amount can be calculated according to the error value, so that the targeted compensation is made, and after the compensation is made, the uniform mixing is carried out.

Step S103: when the liquid level in the tank rises to the standard liquid level, the drainage pipeline is started, and the drainage quantity of the drainage pipeline is adjusted according to the inflow quantity of the perfusion pipeline, so that the perfusion liquid in the tank is dynamically circulated for a standard time.

In the embodiment of the invention, the inner cavity of the endoscope needs to be sterilized, the outer surface of the endoscope also needs to be filled with a certain perfusion liquid, so that the outer surface of the endoscope can be completely soaked in the perfusion liquid, a drainage pipeline can be arranged for preventing the perfusion liquid from overflowing, the perfusion liquid in the sterilization tank is continuously discharged, and when the discharge amount is the same as the inlet amount, the perfusion liquid in the sterilization tank is in dynamic circulation.

In the embodiment of the invention, the dynamic circulation of the perfusion liquid in the disinfection tank specifically comprises the following steps:

predefining a standard liquid level, and marking a basic submerging liquid level in the sterilizing pool, so that an endoscope can be completely submerged; different standard liquid levels can be set according to different endoscopes, or a covering type unified submerged liquid level can be set.

The standard time is predefined, and the corresponding killing time is formulated according to the components of the perfusion liquid, so that the method can be suitable for the buried killing standard and the flushing type killing standard.

Pre-defining standard flow; the basic flow of the perfusion liquid for generating the flushing and sterilizing effects can be limited according to the inner diameter of the pipeline and the flow rate of the liquid.

Detecting the total inflow rate of the perfusion pipeline in unit time, and judging whether the total inflow rate is smaller than the standard flow rate:

if the total inflow is smaller than the standard flow, initiating a delay warning to prompt that the current flow in the disinfection pool is smaller for a worker, and suggesting maintenance; the total input flow has certain defects, the flow is too small to meet the killing standard, and the corresponding killing effect cannot be achieved. And a delay warning can be sent to indicate that the perfusion is continuously carried out at the current total inflow, the required time is long, the sterilization standard does not reach the standard, and a worker needs to intervene to overhaul or replace the sterilization pool. It will be appreciated that the total inflow may be zero, in a flow cutoff condition; the filling effect and the flow rate of the perfusion liquid do not reach the standard, and the sterilization at the moment is not qualified.

If the total inflow is not less than the standard flow, continuing to perform filling perfusion of the current killing pool; the total inflow rate is up to the standard, and perfusion can be normally carried out. The perfusion liquid can be rapidly accumulated in the disinfection tank, so that the liquid level in the disinfection tank reaches a standard liquid level, and the process can be defined as filling perfusion.

Detecting the killing liquid level in the killing tank, finishing filling perfusion when the killing liquid level reaches the standard liquid level, starting a drainage pipeline, and keeping the opening state of the perfusion pipeline; and detecting the liquid level of the killing pool in real time, defining the liquid level as a killing liquid level, finishing filling and perfusion when the killing liquid level reaches a standard liquid level, and entering a dynamic circulation stage. And (5) opening the drainage pipeline and simultaneously keeping the perfusion state of the perfusion pipeline.

Detecting the flow rate of the perfusion liquid of the perfusion pipeline, and adjusting the drainage speed of the drainage pipeline in real time according to the flow rate to enable the perfusion liquid in the sterilizing tank to be in dynamic circulation; the water discharge and inflow are adjusted to be the same, so that dynamic circulation of the perfusion liquid can be formed in the sterilizing pool.

It is understood that the duration of the dynamic cycle may be a standard time to complete the criteria for a flood kill. The inner diameters of the perfusion pipelines and the drainage pipelines are the same, so that only the flow rates of the perfusion pipelines and the drainage pipelines are detected, the flow rate of the drainage pipelines is adjusted, the quantity of influencing variables is controlled, and errors are reduced.

In the embodiment of the invention, after the duration time of the dynamic circulation is detected to reach the standard time, the perfusion liquid in the current disinfection tank is emptied, and the connection between the perfusion pipeline and the cavity channel is disconnected.

Specifically, when the perfusion liquid in the disinfection tank is in a dynamic circulation process, the duration time of the dynamic circulation is detected, and after the duration time reaches the standard time, the perfusion liquid in the tank is drained, and the connection between a perfusion pipeline and a cavity channel is disconnected.

It can be understood that the perfusion liquid in the disinfection tank, the perfusion liquid in the endoscope cavity, the perfusion liquid in the perfusion pipeline and the drainage pipeline are all emptied. The connection between the perfusion pipeline and the cavity interface is not disconnected, the valve of the perfusion pipeline is closed, the perfusion liquid is not conveyed, air conveying is carried out, after continuous bubbles are discharged from the long catheter port of the endoscope, the perfusion liquid in the endoscope cavity is considered to be completely emptied, and the endoscope is taken out to carry out the next operation; and then, opening a drain valve of the sterilizing tank, discharging the perfusion liquid in the sterilizing tank through the drain valve and a drainage pipeline together, and automatically draining the perfusion liquid in the drainage pipeline after the discharge of the perfusion liquid in the sterilizing tank is finished.

Step S104: during the duration of the dynamic cycle, a shut down alarm is issued when a stop of the dynamic cycle is detected.

In the embodiment of the invention, the flow rates of the perfusion pipeline and the drainage pipeline are dynamically followed in the duration of dynamic circulation, and once a fault occurs, the dynamic circulation is destroyed, which can be regarded as dynamic circulation stagnation, and at this time, the liquid level in the disinfection tank may be lowered or raised. When the temperature is reduced, the endoscope is easily exposed out of the liquid level and does not meet the disinfection requirement; when the height of the patient is increased, the perfusion liquid is easy to overflow, so that the environment is polluted and potential safety hazards are caused.

In the embodiment of the invention, when the perfusion liquid in the sterilizing tank is in the dynamic circulation process, when any one of the following conditions is detected: the perfusion pipeline is cut off, the drainage pipeline is cut off, the perfusion pipeline and the drainage pipeline are both cut off, and the flow difference exists between the perfusion pipeline and the drainage pipeline; the dynamic circulation of the current disinfection tank is considered to be stopped, a cutoff alarm is sent out, a worker is warned that the perfusion liquid in the current disinfection tank is cut off, and the worker overhauls or replaces the disinfection tank to carry out perfusion again.

It can be understood that, when the flow rates in the perfusion pipeline and the drainage pipeline are less than the standard flow rate, the current pipeline is considered to be in a cutoff state, and the flow rate of the perfusion liquid in the current pipeline is not enough to complete sterilization meeting the standard, so that pollution residue and cross infection can be caused.

It is understood that the shut off alarm includes flashing of an indicator light, and voice broadcast.
