Problems solved by technology

Since the existing hard medical barrel is replaced by a standable soft bag to hold the hemodialysis concentrate, it is convenient to flatten and store after use; however, in order to facilitate the extraction of the dialysis concentrate from the standable soft bag And without causing mechanical failure, the size of the suction port needs to be set to be much larger than the outer diameter of the suction tube, resulting in the risk of foreign matter falling into the bag during use, and there are bacteria in the air that enters the soft bag with suction , these bacteria present a risk of infection

Embodiment 1

[0044] see Figure 1 to Figure 11 , the soft bag 1 for the hemodialysis concentrate of the present invention comprises a standable soft bag body 2, a tube inlet 3 arranged on the soft bag body 2 for the suction tube to extend into, and a tube inlet 3 arranged on the soft bag body 2 is used to balance the air intake channel 4 of the air pressure inside and outside the bag body and the hand handle 10 that is located on the top of the soft bag body 2 during suction.

[0045] like figure 1 and figure 2 As shown, the soft bag body 2 includes a side panel 20 , a side panel 21 and a bottom panel 22 . The side panels 20 and the side panels 21 are fixedly bonded to form a shell structure at the overlapping points 201, 202; Places 208, 203, 204, 205, 206, and 207 are fixedly bonded by hot pressing to form hot-pressed strips, and the backsheet is formed at the overlapping joints 201 to be bounded by the hot-pressed strips at the overlapping joints 203 and 208. An upturned tip struct...

Embodiment 2

[0060] As a description of Embodiment 2 of the present invention, only the differences from the above-mentioned Embodiment 1 will be described below, that is, the soft bag structure and the airway opening and closing device in the above-mentioned Embodiment 1 are replaced with the following structures to form This example.

[0061] like Figure 12 and Figure 13 As shown, the soft bag body 2 is roughly a right triangular prism shell structure formed by hot-pressing three pieces of side panels at the lap joints. A gas-filled sealing membrane structure, that is, six sealing membrane structures 28 for assisting standing are arranged at the bottom of the soft bag 2 .

[0062] like Figure 12 , Figure 14 and Figure 15 As shown, the airway opening and closing device 6 includes a chute seat 60 fixedly connected to the soft bag body 2 and a slider 62 forming a drawer-type pull structure with the chute 61 on the chute seat 60 . The soft bag body 2 is provided with a vent hole, ...

Embodiment 3

[0068] As an explanation of Embodiment 3 of the present invention, only the differences from Embodiment 1 or Embodiment 2 above will be described below. That is, the gap opening and closing device in the above-mentioned embodiment 1 or embodiment 2 is replaced with the following structure to form this embodiment.

[0069] see Figure 16 to Figure 19 The gap closing device 5 installed in the port tube 30 is an iris-type aperture adjustment mechanism. During use, the blade 51 is driven to rotate by the knob 301 that can rotate relative to the port tube 30 to open the through hole 50. Then, the suction tube is extended. into the inner cavity of the soft bag, and then reversely rotate the knob 301 until the periphery of the through hole 50 is close to the pipe wall of the suction pipe, that is, the gap closing device 5 is used to close the gap between the suction pipe and the pipe inlet 3 , and the gap closing device can adapt to gaps formed by suction pipes of different diameter...

Abstract

The invention relates to a soft containing bag used for hemodialysis concentrates, and belongs to the technical field of medical devices. The soft containing bag used for the hemodialysis concentratescomprises a soft bag body which can stand and a pipe inlet which is formed in the soft bag body and used for allowing a suction pipe to stretch into; the pipe inlet is provided with a gap closing device used for closing a gap between the suction pipe and the pipe inlet; the soft bag body is provided with an air inlet channel which is sealed by an air filter element, and the air inlet channel is provided with an air channel opening and closing device which is used for opening and closing the air inlet channel. Based on an existing soft bag body, by adding the gap closing device and forming theair inlet channel with the air filter element and the air channel opening and closing device, while it is ensured that the hemodialysis concentrates are smoothly drawn from the bag body, the dialysistreatment safety is improved, and the soft containing bag can be widely used in hemodialysis and other medical technical fields.

Description

technical field [0001] The invention relates to a container for medical liquid, in particular to a soft container bag for hemodialysis concentrate. Background technique [0002] Hemodialysis is one of the most effective means for treating kidney diseases. The dialysate used in hemodialysis is usually prepared with hemodialysis concentrate and water according to a predetermined ratio. In order to ensure the quality of the dialysis concentrate, it is necessary to use a sealed container for packaging. For example, the PET container for the hemodialysis concentrate disclosed in the patent document CN204618983U is used, that is, the hemodialysis concentrate is shipped in a hard pharmaceutical cartridge. In order to meet the requirements of hard support, it not only consumes more materials and causes waste, but also is inconvenient to recycle after use. It also needs to occupy the storage space that is already in short supply in the hospital, and also brings heavy tidying work to ...
