Embodiment 1

A kind of mixing bag for tumor radiotherapy locating pad, which uses plastic material, since foamable reaction can produce Heat amount is melted in order to avoid plastics generate heat, and mixing bag uses heat resistant plastice, and heat resistant plastice described in the utility model refers to Under the action of the heat that foamable reaction generates, plastics have high antioxidant, creep resistance and the lasting characteristic of intensity, resistance to thermoplastic Material includes but is not limited to TPU, PET or nylon etc..Plastics eliminate Patients During Radiotherapy compared with aluminium foil material disclosed in original patent The interference effect of middle metallic element.

It is configured to closed bag chamber in mixing bag 1, is folded as shown in Figure 1, plastics are carried out middle part, excess-three is opened Mouth side seals processing forms closed bag chamber, forms 3 edge sealing 2 after 3 open side edges sealing, including one long Side sealing and two opposite short side edge sealing 21 form a closed bag chamber inside mixing bag after edge sealing.It can also be by two Layer plastic film surrounding carries out the bag chamber that edge sealing forms edge sealing, and there are four edge sealing for tool at this time.

Bag chamber is internally configured to two mutually independent material cavities, and the first area Qian Lian is configured between described two material cavities Domain 4 is configured with second one of in described two material cavities between the external world and shallowly connects region 3, sets mixing bag bag is intracavitary Lattice 5, the effect of lattice are that mixing bag bag chamber is separated into two independent material cavities, specifically, the realization of lattice 5 Mode are as follows: mixing bag includes opposite upper layer film and lower membrane, and by fitting up and down on the inside of upper layer film and lower membrane, joint place will be mixed Sealed bag chamber in material bag is divided into two.It is rectangle as shown in Figure 1, mixing bag 1 is whole, in inside rectangle mixing bag Between area be bonded to form lattice 5, wherein the intermediate region of lattice 5 using double faced adhesive tape be bonded, shallowly connect so as to form first The weaker region in region 4, i.e. bonding strength, remaining two side areas 51 are connect in succession by heat, in this way, applying lesser strength When, viscose glue fit area can be separated, and heat connects joint place and will not rupture, i.e., viscose glue fit area is by any material cavity side The first passage that conducting is formed when the extruding force transmitted, realizes the connection of mixing bag material cavity.

Enter in the outer bag of locating pad to guarantee that the foam of foamable reaction generation can go out mixing bag, the two of mixing bag One of a material cavity is configured with second between the external world and shallowly connects region 3；Specifically, as shown in Figure 1, one of them by mixing bag is short Side sealing 21 is arranged to rupturable edge sealing, and the intermediate region of the rupturable edge sealing is bonded by viscose glue realizes edge sealing, rupturable The two side areas heat of edge sealing connects edge sealing, and a remaining short side edge sealing and long side sealing connect realization edge sealing by heat, in this way, construction At in the extruding force transmitted by corresponding material cavity side, double faced adhesive tape mucilage glue surface is unfolded into the second channel of conducting, and its Remaining heat connects edge sealing and is connected firmly, and is not easy to be switched on.

As shown in Fig. 2, being equipped with clips at the lattice 5 and short side edge sealing 21 of mixing bag, i.e., by lattice 5 and short side Viscose glue region on edge sealing 21 is clamped by external clamping element 6, in this way, when in use, it is necessary first to open close in the external world Binder 6, after apply external force conducting first again and shallowly connect region 4 and second and shallowly connect region 3, as shown in figure 3, the utility model offer one Kind clips, for existing common seal food folder, clips include upper clamp plate 66 and lower clamp plate 67, and upper clamp plate and lower clamp plate are logical It crosses gusset 65 and connects the clamp port for forming V-type, clamp port clamps lattice and short side edge sealing 21；Sealing is equipped with inside upper clamp plate Item (diagram is not shown), lower clamp plate are equipped with the sealing strip 63 corresponding to seal groove, and upper clamp plate end is equipped with buckle 61, lower clamp plate End is equipped with card slot 62；And key 64 is additionally provided in the end of lower clamp plate.The clips can also take other forms, not Clips provided by the utility model are confined to, such as existing common shape food container folder or other resilient clamp members.In addition may be used To use simple elastic bookend, only will shallowly connect and be clamped at region, not necessarily must by include shallowly connect region lattice and Seal edge portion all uses clips to clamp.The use of the above clips, sealing clip or bookend can avoid shallowly connecting region easily quilt Mislead, raw material leak the case where generation.
