For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.

FIG. 1 shows a titanium alloy connector (titanium head for short) 300 for connection to a peritoneal main catheter, which comprises a threaded connection section 301, a straight-wall outer contour section 302 and a reduced section 303; wherein, at the necking section 303, the peritoneal tube section of the peritoneal dialysis catheter, i.e. the flexible tube 200, is connected. The diameter of the straight-walled outer profiled section 302 is larger than the outer diameter of the hose 200 to which it is connected. The straight-wall outer contour section is circumferentially distributed with a plurality of flat tangent planes 304, and the flat tangent planes extend from the straight-wall outer contour section to a part of the reducing section 303 and are naturally tangent with the conical surface of the reducing section 303.

In the disinfection treatment for the titanium head, the threaded connection section 301 is a core disinfection area, and in order to ensure that the core disinfection area is sufficiently sterilized and avoid adjacent infection, the part of the straight-wall outer contour section 302 close to the threaded connection section 301 should be sufficiently disinfected.

Fig. 2 shows a schematic view of the structure of a disposable sterilization bag according to the first embodiment of the present invention. The disposable sterilization bag 100 comprises a bag body 101, wherein the bag body comprises two side sheets 101a and 101b with the same shape, and is manufactured by thermally pressing and bonding the edges of the sheets, and the sheets are made of thickened plastic or aluminum foil. The whole forms a cavity with a preset volume, and the cavity is suitable for containing 8-12 ml of liquid. When in actual use, 3-5 ml of liquid is filled in the disinfection bag.

Specifically, the shape of the sheet is a letter-convex. The head 102 is positioned at the top end of the convex shape, and a neck 103 is arranged between the bag body 101 and the head 102.

Specifically, a tearable opening 104 is formed in at least one of opposite side edges of the head portion 102 of the bag body. After tearing, the head 102 is separated from the bag 101 and the neck 103 forms an open mouth. The caliber of the bag mouth is suitable for the titanium head to pass through from top to bottom.

The inner surface of neck 103 is provided with a sealing engagement assembly around the circumference for sealingly engaging the inner wall of neck 103 with the outer wall of hose 200 after the titanium head has been threaded through the mouth of the bag.

closure assemblies

105 and 106 in an open state, from a top view, partially enlarged, to facilitate the insertion and removal of a titanium head into and from the sterilization bag; fig. 4 is a schematic diagram of the disposable sterilizing bag of the preferred embodiment of the present invention showing the

sealing strip assemblies

105 and 106 closed, and showing the closed state of the bag body in which the closed space for sterilizing the titanium head is formed.

As can be seen in connection with fig. 2, 3 and 4, the closure assembly is a sealing strip assembly comprising cooperating

sealing beads

105a, 106a and

sealing grooves

105b, 106b provided on the inner walls of the

necks

103a and 103b, respectively. The seal assemblies 105 and 106 are spaced apart by a distance equal to or slightly less than 3.14 r, where r is the radius of the outer wall of the peritoneal dialysis tubing.

In the spacing region between the two seal strip assemblies, the inner surfaces of the two opposite sheets are respectively provided with semi-cylindrical

elastic seal rings

107a and 107b, which together form a surrounding pipe assembly 107. Specifically, the elastic seal ring is made of felt, rubber or silicone material capable of holding a semi-cylindrical shape, preferably silicone. It can be seen that 3.14 × r

elastomeric seals

107a and 107b just encircle the hose 200 around its circumference, with the remainder of the mouth being sealed by means of a sealing strip assembly.

After the tip is inserted into the bag and immersed in the iodophor solution, the operator presses the sealing

strip assemblies

105 and 106 relatively to form a bag mouth seal, and the elastic sealing rings 107a and 107b enclose the flexible tube 200 and form a seal between the flexible tubes, so that the liquid in the bag body is prevented from leaking out from the outer wall of the peritoneal dialysis catheter.

When the titanium head is taken out, the sheets at the lower part or the upper part of the bag opening are pulled outwards to disengage the

convex strips

105a and 106a of the sealing strip assemblies 1051 and 1052 from the

concave grooves

105b and 106b, and no extra tool is needed for pressing or separating.

In an alternative embodiment, the seal engaging assembly comprises two sets, thereby forming a two-stage seal around the hose and forming a two-stage seal of the bag mouth.

Fig. 5 shows a longitudinal section along the longitudinal centre line of a preferred embodiment of the invention. In this preferred embodiment, as shown in figure 5, the sealing element of the pouch is heat sealed at the junction and incorporates a film 120 located within the pouch interior, the perimeter of which is heat and pressure bonded to the sealing structure of the neck of the pouch and has a bottom which sinks toward the bottom of the pouch. The film includes at least a thinned region 121 in the center of the base. The edges of the film are heat sealed to the bag sheet so that when the seal assembly is opened, the film is oriented above and below the sterile chamber 123 which is sealed to contain the sterile liquid. Thus, the membrane can block the flow of the disinfecting liquid to the bag opening. Thereby preventing the antiseptic solution from flowing out carelessly when the titanium head is not inserted into the bag body. When the titanium head is inserted from the bag opening, the thinning area 121 is damaged by being pressed by the titanium head, so that the titanium head enters the disinfection liquid cavity 123 for soaking disinfection.

In this preferred embodiment, as shown in fig. 6, the bag comprises a bottom sheet 108 for the bag to stand up, the peripheral edges of the bottom sheet being folded down and forming a downwardly extending heat-sealed edge with the inside of the bottom edge of the side sheets 101a, 101b, the heat-sealed edge being adapted to stand the bag on the object surface.

The center of the inner surface of the bottom sheet forms a film disrupting structure 109. The film disrupting structures 109 in fig. 6 have sharp corners that protrude upward. The film and the side wall and the bottom of the bag body form a sterilizing liquid cavity 123 with a lower middle part and a higher periphery. A titanium head accommodating cavity 122 surrounded by the disinfectant cavity is formed above the middle part of the film.

When the film 120 is pressed against by the titanium head, the sharp corner 109 punctures the film 120, and the disinfectant flows from the peripheral part of the disinfectant cavity to the titanium head accommodating cavity through the damaged part in the middle of the film, so that the disinfectant in the disinfectant cavity 123 flows into the titanium head accommodating cavity 122, and the titanium head is immersed therein.

The cusps piercing the film 120 may be accomplished by designing the thinned region 121 of the film 120 to be a distance from the cusps 109, such as when a titanium head is pressed against the film 120, the deformation of the film 120 may cause the thinned region 121 to contact the cusps 109. Alternatively, the sharp corner piercing the film 120 can be accomplished by pressing the bottom sheet, by which the sharp corner approaches the thinned region 121 of the film.

In a preferred embodiment, the bag mouth further comprises a tube clamp for temporarily blocking the passage of liquid in the hose, the tube clamp being disposed above the sealing engagement assembly.

The pipe clamp comprises a first clamping portion and a second clamping portion formed on the inner wall or the outer wall of the side sheets 101a and 101b, respectively, one end of the first clamping portion and the second clamping portion being connected to each other and the other end comprising an operable connection and a disconnection. When the two ends of the first clamping part and the second clamping part are connected with each other, the clamping force between the two parts can block the liquid channel in the hose between the two parts.

In a preferred embodiment, the sealing engagement assembly is disposed over a shoulder of the cam.

In a preferred embodiment, the bag body sheet is thickened aluminum foil paper, PE, PVC or a multi-layer composite waterproof material comprising metal, paper and/or high polymer materials.
