Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a storage and access device for medical sanitary products with an access port. Background Art

[0002] The sterile containers used for storing existing medical sanitary products usually need to be sterilized again after opening. Or the sterile containers are equipped with sterilization equipment, which makes the containers expensive and bulky. For medical sanitary products that are stored in large quantities and frequently used, the above two solutions have defects and need to be improved.

[0003] Many medical hygiene products have different degrees of sterility requirements for their storage environment. For example, masks are medical products that come into contact with the human mouth and nose, and they have specific regulations for sterility and hygiene. In order to meet the sterility and hygiene requirements, existing high-standard masks are packaged individually. This is not economical and environmentally friendly for large-scale mask production.

[0004] In some specific scenarios or special circumstances (such as during the outbreak of infectious diseases), a large number of masks are needed. Figure 1-3 This type of mask is packaged in a roll, like a large roll of toilet paper. Many masks are rolled together, and each roll can contain 500-2000 masks. When in use, the masks can be separated for use by cutting the contact line between the masks with scissors. This type of mask is an emergency mask, which only has a mask body. The mask body is not equipped with ear ropes. The left and right ends of the mask body are respectively provided with ear rope holes for the ear ropes to pass through when in use; the mask body is also not equipped with a nose bridge. The mask body is provided with a nose bridge insertion and a cutout in the middle position for the nose bridge to pass through when in use.

[0005] However, for this type of roll-type mask, due to its large storage capacity, the possibility of long-term storage and the characteristic of frequent use, when using it, the sterile environment for long-term storage of the mask and the prevention of bacterial contamination during the use of the mask should be considered. In the prior art, there is neither a storage and retrieval device matching this type of roll-type mask nor a technical solution to prevent bacterial contamination. Summary of the invention

[0049] Roll-type mask 200 DETAILED DESCRIPTION

[0050] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0051] like Figure 4-10 As shown, the storage and retrieval device for medical sanitary products of the present invention comprises a sealed shell 100, wherein a storage compartment 1 and an retrieval compartment 2 are provided inside the sealed shell 100, and a sealing valve 3 is provided between the storage compartment 1 and the retrieval compartment 2. When the sealing valve 3 is closed, the storage compartment 1 and the retrieval compartment 2 form two independent sealed spaces isolated from each other, thereby effectively preventing external bacteria and other contaminants from entering the storage compartment 1 from the retrieval compartment.

[0052] The storage compartment 1 is used for sealed storage of medical sanitary products. In the present embodiment, the medical sanitary products are specifically masks. Of course, preferably, what is sealed and stored is a roll-type mask 200. The roll-type mask 200 is the mask of a roll-type structure formed by rolling together a plurality of simple masks as described in the above background technology part. Of course, what is sealed and stored in the storage compartment 1 is not limited to the roll-type mask 200, and other types of existing masks can also be sealed and stored in the storage compartment 1.

[0053] Specifically for the roll-type mask 200, a roll fixing shaft 11 is provided in the storage compartment 1, at least one end of the roll fixing shaft 11 is fixedly connected to the storage compartment 1, the roll fixing shaft 11 is used to place the roll-type mask 200, and the roll of the roll-type mask 200 can rotate around the roll fixing shaft 11. Considering the fixation of the mask storage and access device with the outside world in this case, it can be set as follows: the roll fixing shaft 11 and the shell of the storage compartment 1 are integrally formed, and the roll fixing shaft 11 is a hollow columnar structure, one end of the roll fixing shaft 11 is hollow and open to the outside, and the other end is sealed, so that the external fixed shaft can penetrate the hollow part of the roll fixing shaft 11 to play a role in fixing the entire mask storage and access device, so that the body of the entire mask storage and access device can be kept relatively stable to a great extent, making the process of taking the mask smoother.

[0054] In the specific implementation process, the storage cabin 1 is specifically provided with a hatch entrance, and the roll-type mask 200 can be placed in the storage cabin 1 through the hatch entrance for storage. The storage cabin 1 also includes a hatch 12, and the hatch 12 seals the hatch entrance through a snap-fit ​​structure. The hatch entrance can be seen when the hatch 12 is opened, and preferably, a sealing strip is also affixed at the boundary position of the hatch 12 to further improve the sealing effect.

[0055] And preferably, the shell of the storage cabin 1 can also be provided with a transparent window 13, and a chemical indicator card 131 is attached to the transparent window 13, and the chemical indicator card 131 has at least the function of indicating the sterilization index. In this way, the sterile conditions in the storage cabin 1 can be monitored through the transparent window 13 and the chemical indicator card 131. Once the chemical indicator card 131 shows that the sterility requirement is lower than the storage of the mask, it means that the sterile conditions in the storage cabin 1 do not meet the requirements at this time. At this time, you can choose to stop using the roll-up mask 200 or take sterilization measures in the storage cabin 1 to avoid the occurrence of mask contamination incidents; in view of this situation, a sterilization nozzle 14 with an inner opening one-way valve can be pre-embedded in the storage cabin 1. When the chemical indicator card 131 indicates that the sterility requirement is lower than the storage of the mask, the sterilization nozzle 14 can be connected to an external disinfectant delivery pump to spray the disinfectant in the storage cabin 1 for sterilization and disinfection. The disinfectant is specifically not limited to chemical liquid disinfectants, and can also be chemical gas disinfectants such as ozone.

[0056] The mask storage and access device specifically also includes a mask retrieval mechanism, which is used to take the mask out of the storage compartment through the sealing valve into the retrieval compartment; and the retrieval compartment 2 can be provided with an access port, through which the user takes the mask from the retrieval compartment 2. Specifically, an access port can be opened on the side of the retrieval compartment 2 and sealed by a retrieval compartment door 21. When the retrieval compartment door 21 is closed, the entire retrieval compartment 2 is sealed, and when the retrieval compartment door 21 is opened, the access port is exposed.

[0057] In the present embodiment, specifically, the mask taking mechanism is used to first open the sealing valve 3, transfer the mask from the roll-type mask 200 to the taking cabin 2, and then close the sealing valve 3, and the sealing valve 3 is also used to fix the contact line between the mask in the taking cabin 2 and the adjacent mask (i.e., the connecting line between the two masks) when closed, and the user tears the mask off from the taking cabin 2 and takes it out for use, or the sealing valve 3 is used to directly cut off the contact line between the mask in the taking cabin 2 and the adjacent mask when closed. In this case, it is preferred to set a blade 31 at the end of the sealing valve 3, and use the blade 31 to cut off the contact line, so that the mask can fall directly into the taking cabin 2, and the user can directly take the mask from the taking cabin 2. Of course, the specific setting position and setting method of the blade 31 can be set according to actual needs.

[0058] In the specific implementation process of the present invention, the mask taking mechanism may include a first transmission mechanism and a second transmission mechanism, wherein the first transmission mechanism is connected to the sealing valve 3, and the second transmission mechanism is connected to the roll of the roll-type mask 200;

[0059] The first transmission mechanism is used to drive the sealing valve 3 to open or close, and the second transmission mechanism is used to drive the roll of the roll-type mask 200 to rotate only when the sealing valve 3 is opened to transfer the mask to the taking compartment 2.

[0060] Preferably, the first transmission mechanism may include a cam mechanism 42, the cam mechanism 42 includes a cam 421 and a follower 422, the cam 421 is used to drive the follower 422 to reciprocate between a first position and a second position when rotating, and the follower 422 is used to open the sealing valve 3 when reaching the first position and close the sealing valve 3 when reaching the second position; specifically, the follower 422 and the sealing valve 3 can be integrally formed or fixedly connected, so that the follower 422 can drive the sealing valve 3 to move.

[0061] The second transmission mechanism may include a gear mechanism 43, the gear mechanism 43 includes a driving gear 431 and a driven gear 432, the driving gear 431 is a structure with teeth on one side and smooth on the other side, when the sealing valve 3 is opened, the toothed side of the driving gear 431 contacts and engages with the driven gear 432 to drive the driven gear to rotate, when the sealing valve 3 is closed, the smooth side of the driving gear 431 contacts and engages with the driven gear 432 and does not play a transmission role;

[0062] When the toothed side of the driving gear 431 contacts and engages with the driven gear 432, the driving gear 431 is used to drive the driven gear 432 to rotate when rotating. The driven gear 432 is specifically fixedly connected to the roll of the roll-type mask 200, thereby driving the roll of the roll-type mask 200 to rotate, and then driving at least one mask in the roll-type mask 200 to enter the taking cabin 2.

[0063] Of course, the cam mechanism 42 and the gear mechanism 43 are only one possible implementation of the first transmission mechanism and the second transmission mechanism. The specific structural composition of the first transmission mechanism and the second transmission mechanism in the present invention is not limited thereto. Those skilled in the art should understand that as long as the structure can perform the actions of the first transmission mechanism and the second transmission mechanism and realize the corresponding functions, it falls within the protection scope of the present invention. In addition, the mask access mechanism can be set in the storage compartment 1 or in the access compartment 2 in specific practice. Those skilled in the art can make corresponding settings according to actual conditions.

[0064] In the present invention, it is preferred that a corresponding control mechanism be used to control the cam mechanism (i.e., the first transmission mechanism) and the gear mechanism (i.e., the second transmission mechanism). In the present invention, it is preferred that the control mechanism is a rocker arm 41, and the rocker arm 41 can be connected to the cam 421 of the cam mechanism 42 and used to drive the cam 421 to rotate when rotating, and then the cam 421 can drive the follower 422 of the cam mechanism to reciprocate between the first position and the second position when rotating;

[0065] In addition, the rocker arm 41 can also be connected to the driving gear 431 of the gear mechanism 43, so that the driving gear 431 is driven to rotate through the rocker arm 41; in this way, when the sealing valve 3 is opened (that is, when the driven member is in the first position), the toothed side of the driving gear 431 begins to contact and mesh with the driven gear 432, so that the driving gear 431 is driven to rotate through the rocker arm 41, and the driving gear 431 can drive the driven gear 432 to rotate at this time, and then the driven gear 432 can drive the roll of the roll-type mask to rotate, so as to realize the transmission of the mask; when the sealing valve is closed (that is, when the driven member is in the second position), the smooth side of the driving gear 431 contacts the driven gear 432 (that is, the driving gear 4 The toothed side of 31 is disengaged from the driven gear 432), and at this time, the driving gear 431 cannot drive the driven gear 432 to rotate; the gear mechanism 43 is used to drive at least one mask in the roll-type mask 200 to enter the access cabin 2 through the rotation of the driven gear 432. In this embodiment, it is preferred to drive only one mask into the access cabin 2 at a time, and when the driven gear 432 drives the roll-type mask 200 to rotate the length of one mask, the driven member 422 just reaches the second position from the first position, that is, as one mask is transferred from the storage cabin 1 to the access cabin 2, the sealing valve 3 also slowly changes from an open state to a closed state, and when one mask is just completely located in the access cabin 2, the sealing valve 3 is completely closed. When the rocker arm 41 drives the follower 422 of the cam mechanism from the second position back to the first position, since the smooth side of the driving gear 431 is in contact with the driven gear 432 at this time, even if the rocker arm 41 drives the driving gear 431 to rotate, the driven gear 432 remains stationary during this process, and thus will not drive the roll of the roll-type mask to rotate, until the follower 422 of the cam mechanism reaches the first position, the sealing valve 3 opens again, and the toothed side of the driving gear 431 begins to contact and engage with the driven gear 432 again. At this time, the driving gear 431 can be driven by the rocker arm 41, and the driving gear 431 drives the driven gear 432 to rotate, so as to take out a mask from the roll-type mask again into the taking cabin 2, and this cycle is repeated, so that each mask in the roll-type mask 200 can be continuously transferred from the storage cabin 1 to the taking cabin 2 for taking.

[0066] Of course, the rocker arm 41 is only one possible implementation of the control mechanism. Those skilled in the art should understand that as long as the control structure or control switch can control or drive the cam mechanism (i.e., the first transmission mechanism) and the gear mechanism (i.e., the second transmission mechanism) to perform corresponding operations, it belongs to the control mechanism of the present invention and thus falls within the protection scope of the present invention.

[0067] Among them, the above-mentioned rocker arm 41, cam mechanism 42 and gear mechanism 43 are all very mature existing technologies in this field, and their specific implementation methods are no longer repeated here. Those skilled in the art can carry out specific structural implementation based on the above description of the working process of the mutual coordination of several components.

[0068] Of course, the storage compartment 1 and the access compartment 2 are both arranged in the sealed shell 100 to achieve sealing, which is only a possible implementation method, and the present invention is not limited to this. Specifically, as long as the structural setting that can ensure that the storage compartment 1 and the access compartment 2 form a sealed space falls within the protection scope of the present invention; for example, the storage compartment 1 and the access compartment 2 can also be split structures, and the two are two separate sealed structures. In this case, the storage compartment 1 and the access compartment 2 can be detachably sealed and docked. The advantage of this setting method is that the storage compartment 1 and the sanitary products stored therein can be produced as a whole, and their sterility requirements are better guaranteed, and the requirements for the shell material of the storage compartment 1 can also be slightly reduced, and the access compartment 2 can be reused. And, in this case, considering the reduction of production costs, the access mechanism for accessing sanitary products can be placed separately in the storage compartment 1.

[0069] In this embodiment, the above-mentioned structure is used to realize the step-by-step actions of transferring the mask from the storage cabin 1 to the access cabin 2 and taking the mask out from the access cabin 2. First, the roll-type mask 200 located in the storage cabin 1 is taken out to the access cabin 2, and then the sealing valve 3 is closed to seal the storage cabin 1. Then the user takes the mask out of the access cabin 2. Considering that the user may bring in external contamination when taking out the mask from the access cabin 2, the storage cabin 1 has been sealed by the sealing valve 3 between the two cabins at this time. This can minimize the risk of the user bringing external contamination into the storage cabin when taking out the mask from the access cabin 2.

[0070] The action process of the mask access mechanism of this embodiment specifically includes: 1) opening the sealing valve between the storage compartment and the access compartment; 2) taking out at least one mask from the roll-type mask to the access compartment and then closing the sealing valve; 3) transferring the mask to the access compartment, wherein the mask in the access compartment may be separated from the adjacent masks on the roll-type mask, or may not be separated from the adjacent masks.

[0071] In actual working process, the user can realize the above-mentioned action process by operating the rocker arm, and then the user can take out the mask in the access cabin.

[0072] In this embodiment, considering that the masks on the roll-type masks are all simple masks, additional ear ropes and nose clips may be needed as accessories. Therefore, the mask storage and access device may also include an accessory access box (not shown in the figure), in which the accessories of the mask are placed, and the accessories include ear ropes and nose clips; because the ear ropes and nose clips do not have strict sterility requirements, for easy access, the accessory access box can be attached to the sealed shell or located around the sealed shell, that is, it can be integrated with the body of the mask storage and access device or can be installed separately. In this way, after the user takes out the mask from the access cabin, and then takes out the ear ropes and nose clips from the accessory access box, the ear ropes and nose clips can be installed on the mask by themselves, and then the mask can be used normally.

[0073] In order to achieve the maximum degree of sterility, all materials of the mask storage and access device of the present invention are made of antibacterial materials as much as possible. From the perspective of cost saving, in the specific implementation process, only the parts or mechanisms inside the device that come into contact with the mask can be made of antibacterial materials. Preferably, the materials of the storage cabin and the access cabin are antibacterial materials, and the specific antibacterial materials are already in the prior art. The specific type of material can be selected according to actual needs.

[0074] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
