Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sterile flat disposable article entrapment protector used in particular in the medical and laboratory fields and a dispenser for storing and discharging any disposable article. .

In the medical and pharmaceutical fields and in laboratories, it is often necessary to work in completely sterile conditions. Auxiliary parts used at this time must also be sterilized. This is especially true for auxiliary components that are packaged and protected, such as diaphragm filters, culture cardboard discs, finger pads, shoe covers, gloves and plastic sheet caps5, which pose the greatest danger. This means that when taking out sterilized flat disposable items, secondary contamination occurs. Furthermore, the removal of a large number of individually packaged disposable items is extremely tedious, for example in the case of mass medical examinations, and no advantageous solutions have yet been found that reduce the hassle of removing from disposable 8-packs. Not yet.

Therefore, the first object of the present invention is to provide sterile flat disposables such as shoe covers, gloves, caps, sterile cloths and similar traps, bandages, finger pads, diaphragm filters and culture cardboard discs. The objective is to provide protective equipment for products that can be easily removed without risk of cross-contamination. In order to solve this problem, in the first aspect of the invention, a protective device for sterilized flat disposable items is provided with a hose-shaped protective sheet that covers both sides of disposable items arranged at a distance t. The longitudinal edges of the protective sheets are such that the opposing protective sheets can be completely separated, and the protective sheets can be continuously separated between two disposable items or between two groups of disposable items. The protective sheet section has a connecting point that allows the two opposing protective sheets to be completely separated and extends perpendicularly to the longitudinal axis of the protective sheet, and has one sealing section for accommodation in the four gauges of the dispenser. A hose-like protective sheet with a disposable product is wound into a spiral or spiral shape that is formed into a zigzag folded folding unit.

The object of the present invention is to provide a dispenser that allows for complete dispensing.

In order to completely solve this problem, in the construction of the second invention,
A sterile flat disposable product receiving and discharging dispenser is divided into all internal compartments and is spirally rolled or zigzag folded around the disposable product.

A hose-shaped protective sheet? Consists of a magazine for accommodating, and the outlet of the magazine is a sealed disposable item? Is there a width that allows the protective sheet to pass through? at least one opening with an outlet on each side of the outlet;
Pairs of conveying rollers are provided to grasp one side of each of the two protective sheets facing each other and forming the entire hose, and the pairs of conveying rollers are arranged to grip each other for the purpose of separating and spreading the two facing protective sheets. Driven in opposite directions and synchronously, both protective sheets are pulled apart from each other at the longitudinal and transverse joining points, so that the disposable article can be released and removed from the protective sheet (1). There is.

The invention will now be described in detail with reference to the drawings.

The protective device shown in FIG. 1 consists of two layers of protective sheets 1.2 which are joined to each other at their longitudinal edges and thereby form a sheet hose assembly. Disposable articles 5, for example culture cardboard discs G or diaphragm fills 7F, are arranged at full intervals inside the hose, and both protective sheets 1.2 extend at right angles to the longitudinal axis of the protective sheet. They are joined to each other at the joining point. The result is that each toilet item 5 or 8 pairs of disposable items or group of disposable items is placed in every sidetone closed pocket. Figure 1 shows gloves A1.

D - A sterile cloth E, a diaphragm filter F and a culture cardboard disc G are shown schematically, but these items are not normally packed together and are shown together only as an example of disposable items. It's just that. Normally, the same type of each disposable item 5 is designated as a sales unit.

The longitudinal edge 3 and the joint location are configured such that both strip-shaped protective sheets 1#2 facing each other can be easily separated. This may be caused by the fact that the longitudinal edge 3 as well as the connection point 4 is formed by welding or gluing and the connection point structure is weakly constructed as a predetermined separation point. This is achieved by virtue of the fact that the coupling is formed by a sawtooth-shaped coupling indentation in cross-section which facilitates this. However, it is also possible to construct the longitudinal edge 3 without predetermined cutting points and to cut it off using a cutting member 4C arranged on the dispenser of the longitudinal edge 3t.

The hose start has two start tongues 1 which are already separated.
．． 2, and these starting tongues 1 and 2
facilitates insertion into a dispenser (see FIGS. 2 and 3), which will be described later.

A large number of flat disposable items 5, as described above, are folded in a protective sheet 1.2 as a protective device. Connection point Φ when protective sheet 1.2 is folded
It is advantageous if the folding edges are formed and the folding unit is formed in this way. The surface structure shape, ie the spiral body or the folding unit, is the handling unit housed in the dispenser shown in FIGS. 2 and 3. is forming.

The dispenser shown in FIGS. 2 and 3 consists of a box-shaped magazine 6 which is constructed as a folding unit 17 with a protective sheet (1.2) or a spirally wound protective sheet. It accommodates 2. The bottom of the magazine can also be constructed in the form of a slider as a charging opening. However, it is also possible to construct the entire transport device so that it can be pivoted away from the entire magazine 6 in its upper region, and to introduce it into the magazine 6 from above into the folding unit 17'. As shown in FIG. 3, the magazine 6 of FIG. 2 is closed on the front side by a pivot door 6' which facilitates the loading of the folding unit 17. Magazine 6
The outlet 9 is formed by two deflection bodies δ which are horizontally arranged, define an opening range, and are chamfered, and the protective sheets 1 and 2 are respectively moved and pass through the snacking of the two transport roll pairs 10 and 11 that are driven in opposite directions to each other and pass through the two transport roll pairs 10 and 1.

In order to ensure reliable transport, the spreading of the two-wheeled protective sheets 1, 2, which are provided with corrugated grooves or a rubber coating, is carried out and facilitated by specially shaped spreading bodies. This expansion body is formed on two opposing protrusions of the magazine walls which are held in the multi-feed roll pair 10. It may also have the shape of a pair of cutters that cut off the opposing longitudinal edges 3 by internal force.

The transport roll pair 10.11 is connected to a transmission.

In the illustrated embodiment, this transmission is intermeshing with Φ
It consists of two transmission gears 13, 14, 15.1el-, which are driven by an electric drive motor MK, which is schematically shown. However, Nacala, transmission gears meshing with each other 13.14.1

In this case, each disposable item 5 which has been sealed at the same time is at least released so that it can be removed and used according to its intended purpose by means of a sterilized trapping auxiliary element, such as a bottle set (see FIG. 2). In the example, the disposable item 5, which is a culture cardboard disk or a diaphragm filter, is
In this way the filtration device does not require Li without the risk of secondary contamination.
d. Can be placed in a petri dish or similar trap.

A cutter 1δ is preferably provided at the outlet of the two transport roll pairs 10.11, with which the released protective sheet 2 can be cut off.

The dispenser of FIG. 2 may be used suspended, standing or lying down in the illustrated embodiment. For certain disposable products 5, it is advantageous to position the dispenser outlet 9v down m. This is the case, for example, if the disposable item 5 is a thin glove used in the medical field. In this case, it is advantageous if the opening of each glove is directed downwards and emerges from the outlet 9. In this way, the user can put on the gloves one after the other without having to rely on anyone else's help and thus without the risk of cross-contamination. In this case, it is assumed that the user's hands are already in a sterile state based on thorough disinfection. For this purpose, a switch which is not actuated by switching the drive motor M is advantageous. The step-type switching I/C of the drive motor M ensures that only one disposable item 5 is always taken out, and that the separation of the connection point of the subsequent disposable item 5 is carried out at the next switching point and the next one. It can be ensured that the protective sheet 1.2 is unfolded as reserved for the switch operation.

In order to ensure the strength of protection sheet 1.2 and the adaptation to different dimensions of the disposable article 5, the roll gap, ゛ and the pressing force of the rolls located one above the other in the transport roll pair 10.11 are adjusted. It is possible. Similarly, the position of the deflector 8 can also be adjusted by the adjustment member 19.
