Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a tool for opening and breaking the seal of a medical dialysis fluid container. Background Technology

[0002] There are currently two types of sealing caps for dialysis fluid containers. One type includes a sealing cap and an additional plastic film at the opening. The other type has an inward-locking knob and no plastic film inside, but the opening is completely opened after using tools. According to the requirements for bacteria / endotoxins related to dialysis fluid, there is a risk during treatment (at least 4 hours), and the risk is even greater for two people with a longer exposure time.

[0003] Current situation defects:

[0004] 1. Using non-specialized tools to open / unseal the container poses safety and contamination risks (there is a risk of contamination when opening the container; after the plastic seal is completely removed, too much of the opening of the dialysate container is exposed, making it easy for foreign objects to fall in and cause contamination).

[0005] 2. After treatment, the remaining dialysis fluid needs to be emptied and recycled. Due to the irregular opening of the non-specialized tools, the process of emptying the residual dialysis fluid is inefficient and poses safety risks (sharp scissors or knives must be used to cut off the remaining plastic film before emptying; some staff members have been injured while using utility knives to clean it).

[0006] 3. The special improved dialysate cap (pull ring type) often fails, and when recycling the dialysate container and emptying the residual dialysate, the efficiency is low due to the small opening, and the cap cannot be recycled.

[0007] Therefore, there is an urgent need to design a tool for opening and breaking the seal of medical dialysis fluid containers to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a tool for opening and breaking the seal of a medical dialysis fluid container, so as to solve the above-mentioned shortcomings in the prior art.

The film-opening assembly and the film-opening blade are used at least for opening the plastic film.

[0011] The retaining ring has several fixed retaining teeth inside, and the retaining ring has movable retaining teeth inside near the handle. The handle is provided with a clamping mechanism for pushing the movable retaining teeth.

[0012] Preferably, the handle has anti-slip grooves on both the front and back, and anti-slip protrusions with elastic structure on both sides.

[0013] Preferably, the film-opening assembly includes an end plate fixed to the tail end of the handle, and a limiting plate is provided on the outer side of the end plate, and a blade is fixedly provided on one side of the outer wall of the end plate.

[0014] Preferably, one of the limiting plates is provided with a notch, and a protective sleeve fitted onto the blade is engaged inside the notch.

[0015] Preferably, the film-opening tool includes a storage groove at the end of the handle, and a utility knife is slidably disposed inside the storage groove. A sealing plug is inserted into the storage groove. Both the handle and the utility knife are provided with positioning holes, and positioning pins are inserted into the positioning holes.
