Description

Hygienic door system for delivery or receipt of articles, transport container for door system, and grabs for a lock

The gate system of the invention defines an opening in a partition between the hospital ward and a service ward. In today's hospitals, there will be divisions of various kinds between, for example, kitchen departments and actual treatment or care departments of the hospital, and in the walls there will also be openings such as doors or elevator shafts suitable for goods transport.

This also applies to separation between, for example, laboratory areas, storage areas and other places where patients and nursing or treatment staff do not stay. All types of articles and persons move between these areas, and there is a risk that contagious material is transported by persons or articles from one treatment area to another. It should be mentioned that the term "hospital ward" here means a place where patients are transported and receive care or actual treatment, where "service department" will denote a part of a hospital where patients and nursing or care staff have no reason to reside. include any type of warehouse, central kitchens, laboratories, laundries and similar support functions which are necessary for the operation of the hospital but do not require the presence of the patient.

According to the invention, the port system comprises a service port and a container, wherein the container has a container opening and associated removable lid, the outer opening edge of the container ending close to the inner edge of the service system port door when the container is held in the service port, and the port system comprises a detachable gripper gripper with the lid separating container and lid so that only the container's interior becomes accessible from the hospital ward via the service port.

With this gate system, it becomes possible to maintain a reasonable separation between actual treatment or care departments and all types of service departments in a hospital. The exterior surface of the container is thus defined as belonging to the service department and has no direct contact with the actual hospital departments, whereas the inner container is considered contaminated and as belonging to the actual hospital sections, where the patients must necessarily be at associated risk of infection. Thus, should it occur during transport of a container that it receives infectious material on its exterior, this material will not enter the hospital department itself but remain in the service department, and the container exterior is not available from the hospital department at any time.

When containers in a service department are emptied or filled, the interior will come from some contact with the service department, but special measures such as washing the container or other disinfection can be established here, ensuring that no contaminated material migrates from the interior of the container to the outside. on its exterior surfaces. The gripper automatically allows the container to be separated from the lid, without the hospital department coming into direct contact with either the inside or outside of the lid.

In one embodiment of the invention, the system comprises a movable tire panel with a front side facing a hospital ward, and a back side facing a service port where the gripper is provided the middle back of the tire panel and the service port and comprises at least one movable member which in a first position is detachably engaged with a latch. , and in another position releases the lid. This ensures that the gripper can take hold in the lid while the lid is in the service port, but is covered by the movable cover panel. This provides a very good protection of the lid, the outside of the seed is at no time directly exposed to the hospital ward.

In one embodiment of the invention, the gripper is secured to the back of the tire panel so that a lid upon engagement with the gripper is subsequently allowed to move along with the tire panel and so that the tire panel in a first position covers the service port and in a second position the service port. The cover panel can perform various movements, including tilting or turning movements, to expose the interior of the container, but it is preferred that a translational movement, such as longitudinal backing groove, be effected to simultaneously remove the lid from the container and expose the opening of the container.

In the event that the container arrives with material for delivery to the hospital ward, it is preferred that the lid is seated in a vertical container surface and that a natural substrate for material in the container is constituted by a container surface adjacent to the lid. Here, the deck panel with associated gripper and lid can be suitably displaced parallel to an area adjacent to the gate system. Conveniently, several service ports may be grouped into a section, for example, above each other and / or side by side. The interior of the container may be provided with shelves and / or vertical sections so that materials can be presented to the easiest possible pickup or outlet for use. Typically, a group of service ports will have an appropriate control panel, such as a computer screen or equivalent, so that staff can order a given item or item from a service area. Automatic orders can occur if a system is designed to respond automatically to state changes or planned state changes at the hospital ward, such as scheduled treatments or admissions.

In the event that the container arrives for receiving material from a hospital ward, be it waste or biological samples, it is preferred that the lid be formed of a horizontal surface and the bottom of the container is plane parallel to the lid and arranged to naturally support the received material. . This seems most natural as waste in particular can appear in a relatively chaotic state and even unpackaged. Here, the material will lie securely in the container, confined walls will be removed until the lid is returned and attached to the container. In a unitary embodiment of the service gate, the deck panel performs a combination combination from the horizontal to the vertical position along the adjacent partition, for example, by driving along a back-rail with both a horizontal and a vertical course.

In one embodiment of the invention, the release of the lid from the gripper will provide container-lid engagement, while at the same time there will be a one-packing between an opening edge of the container and the lid, thereby ensuring packing pressure. It is important to secure the material in the container, that there is a good connection between the container and the lid, and therefore there is established engagement between the two which is activated as the lid is released from the gripper.

It should be noted that activatable engagement means between the container and the lid can be established either in the container or in the lid or both places. However, it is important that as soon as the lid is released from the gripper, a firm connection to the opening edge of the container is ensured so that a safe packing pressure is established along the entire edge when the lid is attached to the container. This provides increased security against material coming from a hospital ward accidentally to contaminate the outer surface of a container.

It is also a part of the invention that the container may be released from the service system of the port system as retention of the container in the service port is releasable. At the same time, according to the invention, there is a transport unit for the ice service department which is connected to the service port. The transport unit comprises at least one movable support surface for transporting the container to and from the service port. This allows the automatic transport of containers to and from a service port. Conveniently, the transport unit coupled to a service port will establish an automatically controllable transport path to: - one or more storage units such as nearby and / or remote storage, - filling stations, - emptying stations, - laboratory facilities, - kitchen departments, - laundries, - workshops - service ports of other hospital departments.

Other possible service functions may also be conceived, but the key is that any container in the system can at any time in principle be called to any service port. However, with the restriction that there may be two types of containers, each with its own service port, and that ideally there is also a different transport system for each of the two types of containers. In principle, the two types of containers may well be handled by a separate transport system, but it is preferable to keep them separately, as one type of container contains materials which must be brought into contact with the patient and included in care or treatment where the other type of containers contains materials, which has been used or harmed part of a patient and should not be brought near a patient again.

There are quite a few exceptions to this general rule, eg blood transfusions, which must undergo treatment for subsequent delivery to another or the same patient from whom it was taken. Then you decide which of the two types of containers and associated door system you find most suitable for transport.

The invention also relates to a container and a lid for use in a gate system as stated. What is special about this is that at least one locking pawl is provided between the container and the lid, which locking pawl is movable between a position where it holds the lid of the container and a position where the lid is released relative to the container. Such a locking paw is just one of many possible methods of releasably holding a lid, but the movable locking paw has the advantage of being highly abrasion resistant. This is not immediately the case with alternatives such as screw or clamping devices between the lid and container, which tend to wear out and relax over time, so that sufficient packing force is not established.

According to the invention, the container has the further characteristic that the locking pawl engages a resilient element which in a neutral position holds the locking pawl in a position where it holds the lid of the container. The resilient member must then be moved toward the spring direction to move the locking pawl to release the lid. This helps to ensure that there is no accidental release of a lid from a container. At the same time, this means that the resilient element is only moved away from its neutral position when the lids are removed or when deposits are applied. This ensures the long life of the resilient element, because most of the time it is completely un-tensioned.

In one embodiment of container and lid, the resilient member is constituted by an integrally molded unit associated with either the lid or the container, wherein the resilient member also comprises an engaging surface which can engage a gripper member for movement of the resilient member counter-spring direction for movement of the locking pawl. and releasing the lid from the container. Integral casting of the resilient member has the clear advantage that an unbroken surface can be established between the remaining lid or container material. At the same time, it is extremely easy to establish the necessary engaging surface with this process, so that it is possible to externally influence or move the resilient element with a suitable gripper part. Also this engaging surface can be established without breaking the surface, but such that the surface is whole and only has smooth and continuous parts. In an integral molding, a first part of the workpiece is established in an injection mold, and then the reconfiguration injection mold and the remaining part of the workpiece are now injected with at least a boundary established by the first workpiece part. By appropriate choice of materials and process parameters, a highly effective and incomplete bond is achieved between the two blanks, so that there are no establishment gaps between them. One of the workpieces can be constituted by an elastomer which is resiliently resilient and is used here to generate the resilient element.

In one embodiment of the invention, the locking pawl is integrated into the lid and has a locking pin at one end and a connecting eye at the other end, so that the locking eye is in form-fitting engagement with the resilient element as the locking pawl is provided between an upper and a lower surface of the lid. when seated as part of the lid, effectively and securely affected by the gripper while gripping the lid. In addition, the locking pin in the one end has a connecting eye which a gripper part can be easily connected. Connection eyes as mentioned in form-fitting engagement with the resilient element, so that this will always try to pull the locking pawl toward its neutral position. At the same time, this construction allows the locking pawl to be moved by the influence of a surface part of the resilient element. There are significant advantages to this, in that the resilient element, as mentioned, can be formed with extremely clean-friendly surfaces.

According to the invention, the gripper for this has a pin adapted to engage the locking latch, the latch during engagement with the locking latch is movable between the position where the latching latch releases the lid from the container and a position where the latching latch secures engagement between the container and lid, and the gripper comprises at least one further movable element adapted for releasably retaining the lid in engagement with the gripper. Thereby, a physical separation of the two functions such as holding the lid against the gripper and releasing the lid from the container comprises. This means that the two functions can be established independently of each other and with each set of moving organs. It helps to ensure that errors occur, especially because the two sets of moving organs can be designed separately.

It is therefore an object of the invention to provide an application of a container system comprising a container and associated lids as essential elements of a hygienic goods transport system in a hospital.

The invention will then be explained in more detail with reference to the accompanying drawings, in which:

FIG. 10 is a sectional view similar to FIG. 7, but with the alternative embodiment of container and lid,

FIG. 11 is a 3d representation of the container / lid combination, but with a gripper shown ready for engagement with the lid and

FIG. 12 is a back view of the gripper corresponding to the gripper shown in FIG.

In FIG. 1, a front view of a hospital ward 100 is shown on the left of a sample port 1 system for either dispensing or receiving items. As seen in the sectional view on the right, the gate system 1 defines a port 2 in a partition 3 between a hospital ward 100 and a service ward 200 in a hospital. Partition 3 forms a physical separation between hospital ward 100 and service ward 200, which is essential for the port system as the hospital ward is the place where patients undergo treatment and where there will be a viscontamination with disease-causing substances such as bacteria, viruses and the like. The service department 200, on the other hand, is attempted with the system to prevent contamination of the pre-hospital ward. Ideally, the hospital ward100 supplies all of its daily necessities through the service department, and corresponds to all used items back to it as either waste or reusable items. To free the contamination service department, all transportation here takes place in closed containers 50. The port system thus comprises a service port 4 and a container 50, where the container 50 has a single-container opening 51 and associated removable lid 70, and the container outer opening edge 52 corresponds to the inner edge. 5 of the port system service port 4 when the container 50 is held in the service port 4. IFig. 1, the partition 3 is seen with three service ports 4, and in the upper 4 there is no container, while in the lower two there is one container 50.

When a container 50 is secured to a service port 4, a lid 70 can be removed from the hospital ward 100 and the interior of the container will be accessible from there without subjecting the outer surface of the container to formal contamination. This is achieved by the good fit of the inner edge 5 of the service port with the outer edge of the container opening 52 along the lid 70.

FIG. 3 depicts the situation shown in FIG. 1, but seen from service department 200. Here are two containers 50 shown in associated service ports 4 below, while the top service port is empty and without container. Here, the reciprocator 120 is viewed from its side facing the container.

FIG. 2 shows a container 50 with a lid in 3d representation.

The outside of the lid must be protected from being contaminated when it is removed from container 50. Therefore, the gate system comprises a gripper 120. The gripper 120 shown in FIG. 6 and FIG. 12 can be releasably engaged with the lid 70 so that container 50 and lid 70 can be separated. The gripper 120 is arranged so that only the interior of the container becomes accessible from the hospital ward 100 via the service port 4, whereas the lid 70 does not, at any time during normal operation, become accessible from the hospital ward 100.

As shown in FIG. 4, the system comprises a movable tire panel 210 with one-front side 211 facing a hospital ward, and a back side 212 facing a service port 4. In the embodiment presented as the ether, the gripper is positioned between the back 212 of the tire panel 210 and the service port 4, at least one movable member 121 which in a first position is releasably engaged by the lid 70 and in a second position releases the lid 70. The position shown by the lower cover panel 210 iFig. 4 is atypical of the system and indicates a possible position of the service switch 120.

In normal operation, as shown in FIG. 5, the tire panels 210 are sometimes displaced laterally with the lid 70 in engagement with the gripper 120. The gripper 120 is thus secured to the back of the tire panel 210. In normal operation, as shown in FIG. 5, then the interior of the container 50 will be accessible from the hospital ward when the cover panel 210 is displaced away from the service port 4, and at the same time no portion of the lid 70 will be available to receive contamination from the hospital ward 100.

213 denotes a cover plate which, in daily operation, cuts off users for reclining guides or other moving means necessary for the foot cover panel 210 and associated grippers 120 to make the prescribed movements.

Fig. 6 shows the gripper 120 with the moving elements 121 arranged to engage under a flange 71 at each end of the lid 70. Hereby the gripper 120 holds the lid 70 and the lid can then be moved together with the gripper and away from the container 50. The gripper also belongs four pins 122 which are movable in the plane of the lid.

As further shown in FIG. 7, the pins 122 are arranged to move locking pawls 75 in the lid so that the gripper 120 provides engagement between container 50 and lid 70 by displacing the locking pawls 75. Locking pawls or other interlocking means between container and lid can be integrated into either container or lid and here it is found appropriate to embed locking pawls. 75 is closed 70. A gasket 55 between an inner opening edge 60 of the container 50 and the lid 70 ensures a certain packing pressure by the engagement between container 50 and lid 70. This occurs by each locking pawl 75 engaging in corresponding lock openings 53 provided along the container rim.

It is an important element of the invention that the holding of the container 50 ice service port 4 is releasable and that there is a transport unit (not shown in FIG.

1, but shown in FIG. 8) in the service department which is coupled to the service port 4 and the transport unit comprising at least one movable support surface for transporting the container 50 to and from the service port 4. The transport unit can, for example, be a regular conveyor whose operation is controlled automatically via a computer system. The conveyor will then be connected to additional automatic transport paths, as known in, for example, storage systems such as automatic stacking bearings, so that the individual container 50 is automatically movable between several service ports, stack bearings and possible filling and emptying stations.

As further shown in FIG. 7, the locking pawl 75 is engaged by a resilient member 80 which in a neutral position holds the locking pawl 75 in a position whereby the lid 70 holds on the container 50. The resilient member 80 is in the exemplary example of the invention embodied as an elastomer which is molded the lid 70 The resilient member 80 comprises a blind hole 81 with an opening facing the top of the lid. The blind hole 81 has an engaging surface 82 which is arranged to be affected for deformation of the resilient element 80. This means that a pin 122 from the gripper 120 can just as well be accommodated in the blind hole81 so that the sides of the blind hole constitute an engaging surface 82 for movement of the resilient element 80. As the pin 122 during its engagement in the hole displaces in the plane of the cover, the resilient member 80 will deform resiliently, the blind hole 81 being displaced by the pin 122, while peripheral portions of the resilient member 80 remain stationary, being chemically or physically bonded to the other material of the cover. The blind hole is externally attached to the molding terminal to one end of the locking pawl via a connecting opening 76 therein, so that the locking pawl 75 is moved with as the blind hole 81 is moved back and forth by the pin122.

With this arrangement, movement of the resilient member 80 towards the spring direction is possible for movement of the locking pawl 75 and release of the lid 70 from the container 50. This is done by the locking pin 74 being thereby pulled out of the locking opening 53. As explained below, all four pins 122, for example, by a scissor device 140, are moved. is part of the gripper 120.

In the foregoing description, the container 50 has had the lid 70 seated in a single vertical side surface so that a horizontal side surface adjacent the container opening becomes the natural support surface or bottom of the container. As shown in FIG. 2, a box-shaped container is preferred, and the orientation with the lid in the vertical position is not changed during container transport, filling or emptying of containers 50.

However, this orientation is not suitable for transporting material such as waste away from a hospital ward, and thus is presented in the following a container and associated port system wherein the lid of the container is provided in a horizontally upwardly facing surface of the container and where a horizontal bottom opposite the lid forms the natural support surface. for material. An example of a service port which is capable of receiving the container and removing the horizontally stored lid and presenting the lower surface of the container to the hospital ward so that it can be filled naturally from scratch is presented below. The same reference numerals are used here for subjects having the same function as previously described notwithstanding that their design may differ from previously described.

In FIG. 8 is a sectional view through a port system comprising single-service port 4 and a container 50 with associated container opening 51 and lids70. The service port 4 has a tire panel 210 with a front side 211 facing the hospital ward 100 and a back side 212 facing the counter service ward 200, and on the side 212 facing the service ward a gripper 120. The tire panel 210 is movable from a position where it covers the service port 4 to a position as shown in FIG. 9, which exposes the service port. In the cover panel 210 there is a gripper 120 arranged to grip the cover 70, release it from the container 50 and move it with the cover panel in its movement away from the service foot 4.

A conveyer 201 is shown schematically in FIG. 8, comprising a movable support surface 202 as support for the container 50. Conveyor2011 allows the container to be advanced to its position in the container port, and also permits transport away from the container port 4. Typically, in connection with the conveyor in the service department 200, a branch network network of conveying units will be provided. , emptying and filling stations as well as a washing station for containers 50. Such a system is known from industrial production companies of various kinds and is not explained here. The conveyor 201 is also not explained in more detail, but may, for example, further comprise raising and lowering means (not shown) so that the container can be moved in a vertical direction, thereby closing closely all of its outer opening edge towards a corresponding opening in the service port 4. Hereby it can be ensured that only the interior of the container is accessible from the hospital ward, which is important as it ensures that the outside surface of the container is not contaminated and thus contaminant rich can migrate from the hospital ward and into the service ward. It should be noted that if, for example, a carrier surface such as a conveyor belt or a robotic gripper in the service department is contaminated with an infectious substance, it can in principle be deposited in small quantities on the outside of any container. Should this happen by accident, in the system shown there will be less risk of contaminant migration into a hospital section, so that the outside of the vessels does not come into direct contact with the hospital sections.

In FIG. 9, the cover panel 210 is seen in the position where it exposes the service port 4 and in the position where it covers a service port 4, with the two service ports placed side by side. Here is also seen the container 50, now open, with the lid 70 seated on the back panel 212 retained here by the gripper 120 and outwardly visible and inaccessible from the hospital ward 100. A backdrop track 6 is schematically shown, and serves as a guide for the deck panel 210's movement between the two positions.

FIG. 10 is a sectional view through the locking mechanism between the lid 70 and the container 50, but contrary to FIG. 7, the lid here is mounted horizontally on an upper edge of the container 50. Here, the locking pawl 75 has a hook-shaped bottle 77, comprising a locking pin 74, which is shown to engage the locking opening 53. The construction functions in the same manner as described with reference to FIG. 7, except that the locking pawl has to be moved opposite to release the lid 70 from the container 50.

The advantage of both the one shown in FIG. 7 and the one shown in FIG. 10, and in particular, the contiguous design of the resilient element 80 with the rest of the lid 70 provides security against various contaminants, such as biofilms or viruses, finding cracks and cracks in which they can be found and, where appropriate, attached. survive for a long time and spread the ice service department.

In the following, grippers for removing the lid on one and the other, respectively, of the two sample containers, will be reviewed. Common to the train rribers is that they comprise two sets of engagement means relative to the lid, wherein the first set of engagement means is arranged to hold the lid countermeasure, and the second set of engagement means is arranged to move one or more locking posts for releasing or holding the lid against container.

In FIG. 11, a gripper 120 is shown on its way to engagement with a cap of the type described with reference to FIG. 8. In this gripper, the pins 122 are moved by backing plate 130,131, so that they can move the resilient members 80 back and forth so as to pull the hook-shaped latch 75 out of or into engagement with the lock opening at the upper edge of the container 50.

In FIG. 12, the back of a gripper of the same type as shown in FIG. 6. Here the pivot movement is controlled by a scissor mechanism 140, and this sometimes has mechanical motion input a pin actuator 141. Such scissor mechanisms are well known and will not be described in detail here, but the man simultaneously permits the movement of the pegs in the gripper's plane, either towards one-way center line 145 or away from center line 145.

The movement of the movable member 121 which is arranged to engage below a protruding flange 71 on a lid 70 is controlled here by its center actuator 142.

Displacement of the gripper 120 itself to ensure proper engagement of intermediate pin 122 and blind holes 80 as well as between the movable member 121 and a lid flange 71 can be effected by raising lowering actuators 147, which are designed to move the entire gripper 120 in its entirety relative to the tire panel 210, on which the gripper 120 is mounted. This movement is necessary to ensure correct positioning of the moving members 121 relative to the flange 71 of a lid 70 and to lower the pins 122 into the blind holes of the lid 70.

Control from the hospital department of the container stock in an underlying transport and storage system can be effected, for example, via input to a computer screen or voice-controlled input to terminals arranged therefor. This is not shown in detail, but it makes sense to see all containers as part of a single warehouse, and thus any hospital department can call any container or subset of a warehouse to a given service port. Thus, the vast majority of supplies, such as nursing, medication, surgical equipment, linen, disinfectants and many other equipment for daily operation of treatment and care sections in a hospital can be supplied to the individual sections at the relevant time of use. Likewise, the gate system allows transporting materials and items away from a single-hospital ward. These are not just waste and used items, but also items such as samples of body fluids, biopsies, amputees or surgical organs or organs, imprints of body parts and many other items to be transported from a hospital ward and further treatment at eg a laundry. , a kitchen, a waste center or a laboratory. All of the types of transport mentioned here will be manageable with the port system and associated transport container as described above, and it should be emphasized that the transport is separate from the self-treatment area so that cross-contamination between hospital sections with pathogenic agents can be completely avoided. The logistical and bacteriological benefits are significant here, and in particular are due to the fact that the interior of the single container can be considered as part of the treatment area, and thus potentially contaminated, whereas the exterior of the container belongs to the service department and should be considered as uncontaminated. It sets special requirements for the gate system to maintain this separation, requirements that are honored with the disclosed invention.
