Detailed Description

The invention is further illustrated with reference to the following figures and examples.

Example 1: a cleaning device for medical instruments is shown in figure 1, which can be seen to comprise a base 1 which can be placed on a workbench or the ground or fixed, a central shaft 2 is vertically fixed at the center of the base 1 on the basis of the base 1, and a rotary drum 3 is sleeved on the central shaft.

Specifically, as can be seen in fig. 11, one form of the drum includes a cylindrical body 30 and a central hub 38, with the annular region between the inner wall of the cylindrical body 30 and the outer wall of the central hub 38 being further divided into a plurality of functional zones by a plurality of radially spaced partitions 39, respectively. The drum form, as exemplified in fig. 11, is divided into four functional zones, namely an access zone 31, a foam wash zone 32, a decontamination zone 33 and a sterilization zone 34. According to actual use requirements, the diameter of the rotary drum is generally within the range of 30-80cm, and the base, the cover plate and the corresponding isolation area are correspondingly designed according to the type of the rotary drum.

In the present embodiment, the central shaft is fixed up and down, and the rotary drum 3 is sleeved outside the central shaft 2 to rotate. The power for driving the rotary drum to rotate can be driven by manual stirring, but also can be driven by power, for example, a driven gear or a belt wheel is arranged on a central shaft sleeve of the rotary drum and is driven by a motor, or a gear is arranged on the outer circumference of the rotary drum and is driven by the motor.

One of the purposes of the rotation of the rotary drum is to meet the sequence of the instrument cleaning process, transfer various cleaning steps to subsequent processes after finishing, and realize continuous and continuous cleaning operation. The other purpose of the rotation of the rotary drum is to facilitate the manual operation of the cleaned instrument in the corresponding area, and when the rotary drum rotates to enable each functional area to approach the operator, the operator performs corresponding operation on each functional area. The third purpose of the rotation of the rotating drum is to facilitate the corresponding functional subareas to be connected with external mechanisms, such as the butt joint of a foam washing area and a breathing mechanism.

The vertical columns 4 are vertically fixed on the edge of the base 1, and in the figure, at least two vertical columns 4 are needed, and the tops of the vertical columns 4 are fixed through top beams 13 to form a stable frame structure.

The upper side of the middle shaft is sleeved with a cover plate 5, as can be seen from fig. 3, the center of the cover plate 5 is provided with a center sliding sleeve 54, and the center sliding sleeve 54 is sleeved outside the middle shaft 2. The edge of the cover plate 5 is connected with edge sliding sleeves 6, and each edge sliding sleeve is sleeved on the corresponding upright post 4 in a matching way and can slide. Meanwhile, a vertical push-pull mechanism 7 is connected between the upper side of the cover plate 5 and the top beam 13, and the cover plate 5 is driven by the vertical push-pull mechanism 7 to be capable of covering the upper edge of the rotary drum in a sealing manner or being separated from the rotary drum. The state of the cover plate and the rotating cylinder which are tightly buckled after being acted by the vertical driving mechanism 7 is shown in figure 2.

In this embodiment, the interior of the drum 3 is divided into a plurality of functional zones by the partition wall 39, including at least a foam washing zone and a sterilization zone, and a cleaning zone, i.e., at least three functional zones are required. When the three partitions are divided into equal parts by 120 degrees, and when the 4 partitions are divided into equal parts by 90 degrees, the three partitions are divided into equal parts by 120 degrees. In the four subareas of fig. 11, the rotating drum rotates clockwise or counterclockwise when rotating, so that the four subareas are distributed to pass through the four stations and turn to an operator in sequence, and the operation is convenient. As can be seen from fig. 3, the cover plate includes a support ring 51, a hollow area 52 and a blocking area 53 (the fourth station corresponds to four sub-areas of the cover plate, and the positions of the four functional areas of the rotary drum are changed, but the fourth station is unchanged), because the cover plate does not rotate along with the rotary drum, when the access area or the cleaning area of the rotary drum is rotated to the operating position, the cover plate should not seal the sub-area, so that the cover plate operates through the hollow area, and when the foam cleaning area and the sterilization area of the rotary drum are rotated to the corresponding positions, the cover plate should seal the corresponding sub-area.

In order to improve the sealing performance of the cover plate and the corresponding functional area, an upper sealing ring 55 may be fixed at the edge of the cover plate sealing area 53, and a lower sealing ring 56 may be fixed at the upper edge of the corresponding functional area.

When the rotary drum rotates to the position opposite to the corresponding subarea, the rotary drum is prevented from deflecting by taking the scribed line as a reference or restraining the rotary drum by a stop component. When the rotating drum is driven to rotate by power, a position sensor can be installed at the corresponding position of each functional area, and the controller detects the signal of the position sensor to drive the rotating drum to rotate and stop or lock (for example, lock the rotating drum by an electromagnetic lock).

As can be seen from the schematic appearance of the device shown in fig. 1, the corresponding pipes or power lines applied to the functional regions can be disposed at the corresponding positions on the cover plate.

The cover is capable of enclosing at least the foam wash zone and the sterilization zone. Regarding the foam washing area, the cover plate closes the area to form a sealing area, and a transverse interlayer is arranged in the middle of the foam washing area, so that the foam washing area is divided into an upper chamber and a lower chamber, as shown in fig. 5 and 9, the interlayer is in the form that a supporting grate 816 or a keel assembly is fixed in the middle of the inner wall of the foam washing area, a net layer is arranged on the upper side of the supporting grate or the keel assembly, and the cleaned instrument is arranged on the net layer.

An upper through hole and a lower through hole are sequentially arranged on the upper part and the lower part of the outer circumferential side wall of the foam washing area, the upper through hole and the lower through hole respectively correspond to the upper cavity and the lower cavity, as shown in fig. 6, a connecting seat 809 is fixed on the outer wall of the foam washing area, an upper conical socket 810 is arranged on the upper side of the connecting seat 809, and a lower conical socket 811 is arranged on the lower side of the connecting seat 809. The self-sealing blocking piece 833 is designed inside the upper cone socket 810 and the lower cone socket 811, for example, a plane is arranged at the position of the hole of the inner wall of the upper cone socket 810 and the lower cone socket 811, the plane area is covered with a cover plate, the upper side of the cover plate is hinged in a shaft hole at the upper side of the hole through a pin shaft, the cover plate sags downwards under the action of self weight to close the hole, but can be pushed away by the upper cone plug 807 and the lower cone plug 808. Since the diameter of the aperture does not need to be large, the area of the cover plate does not need to be large to cover the aperture. The upper cone socket 810 and the lower cone socket 811 may also have self-sealing valves mounted therein.

A breathing mechanism 8 is shown in figure 7 and comprises an upper piston cylinder 801 and a lower piston cylinder 802, wherein the two piston cylinders are fixed into a whole. Each piston barrel is internally sleeved with a piston 806, the front ends (left ends) of the upper piston barrel and the lower piston barrel are respectively provided with a hole and are provided with an upper conical plug 807 and a lower conical plug 808, and the upper conical plug 807 and the lower conical plug 808 at the positions can be matched and inserted into the corresponding upper conical socket 810 and the corresponding lower conical socket 811, are sealed and can be pulled out. In this embodiment, the upper and lower piston cylinders can move laterally in a small range, specifically, a screw sleeve 803 is fixed at the bottom of the lower piston cylinder, a screw 804 capable of rotating is installed on the base through a shaft sleeve, and a rotating shaft of a motor 805 is connected with the screw 804, so that the motor can rotate to drive the conjoined piston cylinder to approach or leave to one side of a connecting seat 809 simultaneously, and the upper cone plug 807 and the lower cone plug 808 can be inserted into and pulled out of a corresponding upper cone socket 810 and a corresponding lower cone socket 811 in a matching manner.

The reciprocating driving mechanism for driving the up-and-down piston to move can be a linear driving mechanism, such as an electric push rod or an air cylinder, and the like, which are respectively arranged on the up-and-down piston, or a cylinder oil path control system as shown in fig. 7 can be adopted. The oil pump 813 draws oil from the oil tank 812 into the reversing valve 814, and the controller controls the valve rod of the reversing valve to reciprocate to supply and return oil to the oil pipe 815. Therefore, the front side chamber of the piston is a detergent chamber, the rear side chamber of the piston is an oil chamber (which can also be a water chamber or an air chamber, and the water chamber or the air chamber is similar to the oil cylinder oil circuit control system), and the piston can also be a conjoined double piston.

Based on the above structural form of the medical instrument cleaning device shown in fig. 1-8, an instrument to be cleaned is placed in the access area 31, an instrument with a larger volume should be disassembled for placement, the device is rotated or started, the instrument to be cleaned is stopped after being rotated to a position corresponding to the washing area 32, the vertical driving mechanism 7 works to seal and press the cover plate 5 on the upper edges of the washing area and the sterilization area, then the controller controls and drives the breathing mechanism to approach to one side of the connecting seat 809, the upper cone plug 807 and the lower cone plug 808 are inserted into the corresponding upper cone socket 810 and lower cone socket 811 in a matching way, the upper piston and the lower piston are driven to respectively reciprocate by the reciprocating driving mechanism, and then the foam detergent in the foam washing area is driven, so that the foam detergent in the foam washing area can reciprocate in the net layer between the upper cavity and the lower cavity, and further the instruments on the upper side of the net layer are repeatedly washed. The repeated washing mode of the foam detergent with pressure can press the foam detergent into the interior of the instrument or the groove of the open area, so that the interior and the exterior of the instrument can be fully washed by the foam. The arrangement of the reciprocating cleaning times is based on thorough cleaning, and when the foam washing area is cleaned in a sealing way, the next batch of appliances to be cleaned in the access area 31 is not influenced, or the appliances are taken out. The pipe for injecting the foam washing liquid or the clean water into the foam washing area can be fixed on the cover plate, such as the first liquid inlet pipe 9 in fig. 1. After the foam washing, the washing liquid in the foam washing zone is discharged through a drain pipe 12 at the bottom. When the medical instruments in the same group are washed, the washing liquid can be discharged after the last batch of washing is finished, so that waste is avoided.

The upper side of the purification area 33 is open, so that the foam cleaning solution in the process can be washed by clean water to keep the surface of the utensil clean. The sterilization zone 34 should also be sealed by a cover plate, and the sterilization means of the sterilization zone can be spraying sterilization liquid, or sterilizing by steam, or sterilizing by ultraviolet lamp and ozone. The upper side of the cover plate corresponding to the sterilization area can be fixedly connected with corresponding pipelines, such as a second liquid inlet pipe 10 and a power line 11 in the figure 1.

After the rotary drum of the device rotates, the inside and outside all-around cleaning of the medical appliance can be realized, and the continuous batch circulating cleaning is realized, so that the operation is simple, the use is convenient, and the cleaning process cannot be omitted.

Compared with the cover plate with the hollow structure shown in fig. 3, the present embodiment does not exclude the fully-enclosed disc-shaped cover plate, when the disc-shaped cover plate is used, the cover plate needs to be operated in a lifted state when the cover plate is used for storing and taking out and washing with clean water, the cover plate needs to be opened after the washing and sterilization are completed, the cover plate is not as efficient as the hollow cover plate can be used for storing and taking out and washing with clean water while washing and sterilization are performed, and obviously, the efficiency is low.

Example 2: the improved scheme based on the embodiment is that the rotary drum is divided into more subareas, and the sealing cover is matched with the rotary drum and is also matched with a plurality of hollowed or blocked areas. As shown in fig. 12, a form of dividing the drum into six sections, each section being, in order from (r), (c), and (c), a put-in section 37, a washing section 32, a cleaning section 33, a drying section 35, a sterilizing section 34, and a take-out section 36. The embodiment is suitable for application of more detail division and more detailed cleaning process. The present embodiment can also be applied to the washing, sterilization and packaging processes of the corresponding appliance production process. The device is butted with packaging equipment, namely the packaging equipment is arranged at the position of the taking-out area 36, or the taking-out area 36 is butted with an inlet of the packaging equipment, so that the automatic continuous production and application of cleaning, drying, sterilizing and packaging of corresponding appliances are realized.

Example 3: on the basis of the embodiment 1, the partition layer positioned in the washing area comprises the partition plate 818 and the net layer 817, the partition plate is positioned at the outer edge, the net layer is positioned at the middle part, and the structure is applied to ensure that the foamed washing liquid in the upper cavity and the lower cavity must pass through the passage area which is only the net layer, so that the instruments positioned on the net layer can obtain more concentrated and pressure-enhanced foamed washing liquid, and the washing efficiency and the washing effect can be improved.

Based on the above structural form, on the basis of all the mesh layers in embodiment 1, a partition plate with a hollow-out structure in the middle is fixedly sleeved, so that the blocking area of the partition plate is positioned at the outer edge, the hollow-out area of the partition plate is positioned at the middle, and the foam cleaning solution in the upper cavity and the lower cavity can pass through the channel area which is only the mesh layer.

Example 4: in addition to example 1, the compartment located in the wash zone includes a partition 818 and a mesh cage 820. Specifically, as shown in fig. 9, the partition 818 includes a blocking area at the outer edge and a rectangular through hole 819 (a hollow-out area) at the middle portion, a reinforcing frame 822 is fixed at the edge of the rectangular through hole 819, shaft seats or shaft holes are respectively fixed at two ends (two radial ends) of the reinforcing frame 822, a rotating shaft is installed at the center of each of two ends of one mesh cage 820, and the rotating shafts at the two ends are respectively sleeved in the corresponding shaft seats or shaft holes in a matching manner and can rotate freely. The net cage is a rectangular body or a cylinder, one side of the net cage is provided with a cover, and the cover is arranged on the net cage main body in a turnover or drawing mode. After the utensil is placed in the net cage and the locking cover is sealed, the net cage rotates to carry the utensil inside the net cage to turn over. Therefore, the embodiment can provide the function of overturning the appliance, so that the appliance can be repeatedly subjected to foam washing from multiple angles according to the overturning condition of the appliance in the process of making the foam washing liquid to and fro the net cage.

Example 5: on the basis of the embodiment 4, compared with the installation mode of the unpowered mesh cage in the embodiment 4, a power component can be installed on the mesh cage rotating shaft to drive the mesh cage to be installed at a certain rotating speed and turn over at a constant speed.

One of the modes for driving the cylinder mould to rotate is that a speed reduction motor or a stepping motor is arranged on the outer side wall of a rotary drum of the washing area, and a rotating shaft of the motor extends into the washing area and is in transmission connection with the rotating shaft of the cylinder mould. The mounting area of the motor is located in the area between the upper cone receptacle 810 and the lower cone receptacle 811 and does not interfere with the mating insertion of the upper cone plug 807 and the lower cone plug 808 into the corresponding upper cone receptacle 810 and lower cone receptacle 811.

The second way of driving the rotation of the netpen is to adopt the structural form as shown in fig. 10, that is, a spiral blade 823 is fixedly sleeved on the rotating shaft 821 of the netpen 820, and the outer edge length of the spiral blade 823 can cover the inner ports of the upper cone socket 810 and the lower cone socket 811, so that when the breathing mechanism 8 works, the foam detergent from the upper cone socket 810 and the lower cone socket 811 drives the spiral blade 823 to rotate when pushing the whole washing liquid to flow, and further drives the netpen 820 to rotate. This regular reciprocating motion from the upper cone 810 and lower cone 811 receptacles enables the helical vane 823 to rotate in only one direction and continue to rotate. Therefore, the foam washing liquid comes and goes to the process of the net cage, so that the appliance is regularly overturned, and the foam washing liquid is continuously pressurized and washed from the upper part and the lower part of the overturned appliance, and the function of repeatedly washing the appliance from multiple angles is achieved.

Example 6: another medical instrument cleaning device is shown in fig. 13 and comprises a base 1 which can be placed on the ground and fixed, a plurality of columns 4 are vertically fixed on the periphery of the base, and a top plate 15 is fixed on the top of each column 4.

The center of the base 1 is provided with a shaft seat and a lower bearing, and the center of the top plate 15 is provided with a shaft hole and an upper bearing. A middle shaft 2 is fixed at the center of the rotary drum 3, and the upper end and the lower end of the middle shaft 2 are respectively arranged in the upper bearing and the lower bearing. The rotating drum can be driven by people to rotate, and a motor 18 can be arranged on the upper side of the top plate 15 and drives the central shaft 12 to rotate through the motor.

There is apron 5 at the rotary drum upside, and the periphery of apron 5 is fixed with the marginal sliding sleeve, and each marginal sliding sleeve respectively the suit can be followed vertical slip on corresponding stand. The center of the cover plate is provided with a middle sliding sleeve which can be sleeved on the outer side of the middle shaft 2. The cover plate 5 can be driven by the vertical driving mechanism to slide up and down.

The structure of the drum is as in example 1 or example 2, and is not described in detail. The breathing mechanism on the side of the drum washing zone may also take the form of embodiment 1 and will not be described in detail. The structural form of the cover plate used in the present embodiment may also be the structural form of embodiment 1 or embodiment 2, and will not be described in detail.

Example 7: on the basis of

embodiment

1 or 6, another form of breathing mechanism is used. The breathing mechanism is shown in fig. 14 and comprises a closed housing 824, on the inside of which is mounted by means of bearings a crank 825, which, as can be seen, comprises a central shaft and two eccentric shafts which are symmetrical about the center. The positions which are positioned on one side of the closed shell and correspond to the two eccentric shafts are provided with mounting holes and are respectively provided with an upper piston cylinder 801 and a lower piston cylinder 802, the upper piston cylinder and the lower piston cylinder are respectively sheathed with a piston 806 in a matching way, the rear ends of the upper piston and the lower piston are respectively hinged with a swing rod 826, the rear ends of the upper swing rod and the lower swing rod are respectively hinged with a connecting rod 827, and the rear ends of the upper connecting rod and the lower connecting rod are respectively hinged on the upper eccentric shaft and the lower eccentric shaft. Therefore, after the central shaft rotates, the upper eccentric shaft and the lower eccentric shaft alternately move back and forth, and the upper piston and the lower piston are driven by the corresponding connecting rods and the corresponding swing rods, so that the upper piston and the lower piston respectively reciprocate back and forth in the upper piston cylinder and the lower piston cylinder alternately.

The breathing mechanism can be in sealing abutment with corresponding upper cone socket 810 and lower cone socket 811 on the outer wall of the washing zone in two ways. One way is that: an upper cone plug 807 and a lower cone plug 808 are respectively fixed at the front ends of the upper piston cylinder and the lower piston cylinder, a slide rail is installed at the bottom of the closed shell and is driven to move in a reciprocating manner by a straight line, and the upper cone plug 807 and the lower cone plug 808 are inserted into and pulled out of a corresponding upper cone socket 810 and a corresponding lower cone socket 811 in a matching manner. The other mode is as follows: the sealing housing 824 is fixed and immovable, but a combined sliding sleeve as shown in fig. 14 is sleeved on the outer sides of the upper and lower piston cylinders, the combined sliding sleeve comprises a conical plug sleeved on the outer side of the upper piston cylinder and a conical plug sleeved on the outer side of the lower piston cylinder, the middle parts of the upper and lower conical plugs are fixed together and connected by an electric push rod 823, the combined sliding sleeve can be driven to move back and forth by the electric push rod 823, and then the upper conical plug and the lower conical plug are inserted into the corresponding upper conical socket 810 and lower conical socket 811 in a matching manner and are pulled out.

The above-mentioned rotation mode of the central shaft can be directly connected with the motor in a transmission way, or a driven gear 830 is arranged on the central shaft as shown in the figure, and a driving gear 829 is arranged on the rotating shaft of the motor 828, so that the driving gear is meshed with the driven gear.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. For example, in embodiment 1, in order to drive the conjoined piston cylinder to approach or depart from the side of the connecting seat 809, a slide rail may be provided between the bottom of the lower piston cylinder and the base, and the upper tapered plug 807 and the lower tapered plug 808 are driven by an electric push rod tool to be inserted into and pulled out of the corresponding upper tapered socket 810 and lower tapered socket 811 in a matching manner. For example, on the basis of embodiment 1, the upper side of the cover plate 5 is not provided with a vertical driving mechanism, the manner of driving the cover plate 5 to move up and down is driven by manpower, the edge sliding sleeve is fixed at a specific height of the upright column by installing a locking wire on the edge sliding sleeve, and the cover plate is locked after being sealed on the upper side of the cylinder body. For example, a sewage buffer tank 19 (as shown in fig. 13) fixed to the base may be disposed outside the rotary drum, and the sewage outlets located in the functional areas of the rotary drum are controlled to be discharged into the sewage buffer tank 19, and then the sewage is discharged from the total sewage outlet of the sewage buffer tank in a unified manner, so that the self-sealing blocking pieces are not necessarily designed inside the upper cone socket 810 and the lower cone socket 811 based on the design basis.
