Description

Technical Field

[0001] The utility model relates to the field of gastric lavage pipe joints, in particular to a disposable external gastric lavage machine filter joint. Background Art

[0002] Since the working nature of the gastric lavage machine determines that its interior will be exposed to various harmful substances, the filter joint needs to be cleaned and disinfected frequently to ensure the hygiene and safety of the equipment.

[0003] The filter mesh of the filter joint is small and easy to clog; it needs to be cleaned and replaced frequently, which increases the workload of medical staff; the filtration efficiency is limited and may cause harmful substances to remain; in the process of cleaning the traditional filter joint, chemical cleaning agents are needed. Since the existing gastric lavage machine cleaning fluid mainly uses three types of Jianzhisu, peracetic acid, and chlorine-containing disinfectant, and the gastric lavage machine system is closed and difficult to volatilize, substance residue is almost inevitable, and the above substances will have a certain impact on the human body. For example, "Study on the adverse effects of peracetic acid air disinfection on human health" clearly pointed out that after the comet experiment, peracetic acid was confirmed to cause damage to DNA and cause certain irritation to the skin and mucous membranes, and "Study on the stability of medical peracetic acid disinfectant during use_Sheng Bing (1)" showed that even after 14 days of testing, the decline rate of 0.15% and 0.18% peracetic acid solutions was only 33%, and the residual rate was relatively large. The same chlorine-containing disinfectant will remain on the surface of objects after use and evaporate into the air. Its pungent odor will irritate people's respiratory tract, and the chlorine in it will also pollute water sources, thereby increasing the risk of cancer and deformities. These cleaning agents may contain chemicals that are harmful to the environment and will also pollute water bodies and soil.

[0004] In summary, the filter connector of existing gastric lavage machines is difficult to clean and requires a lot of time and effort. This not only affects the work efficiency of medical staff, but may also lead to cross infection due to incomplete cleaning. Utility Model Content

[0005] The purpose of the present utility model is to solve the problem that the filter connector of the existing gastric lavage machine is difficult to clean, which requires a lot of time and energy; this not only affects the work efficiency of medical staff, but may also cause cross infection due to incomplete cleaning. The utility model proposes a disposable external gastric lavage machine filter connector.

[0006] The utility model is realized through the following scheme:

[0007] A disposable external gastric lavage machine filter connector, comprising a conical filter screen, an activated carbon filter element, a support structure, a filter screen, a housing, an upper end connection nozzle, and a lower end connection nozzle;

[0008] The upper end nozzle is connected to the upper part of the inner cavity of the shell, the lower end nozzle is connected to the upper part of the inner cavity of the shell, and a threaded interface is provided at the bottom of the lower end nozzle. The conical filter screen, activated carbon filter element and filter screen are arranged in the inner cavity of the shell from bottom to top. The inner cavity wall of the shell is provided with barbs for limiting the movement of the activated carbon filter element. A support structure is wrapped in the activated carbon filter element. The bottom end of the support structure is connected to the top end of the conical filter screen, and the top end of the support structure is connected to the bottom end of the filter screen.

[0009] Furthermore, the side portion of the support structure is fixedly connected to the inner cavity wall of the shell.

[0010] Furthermore, the vertical cross section and / or the horizontal cross section of the support structure is cross-shaped or P-shaped.

[0011] Furthermore, the outer circle of the top end of the upper end nozzle is provided with a circle of arc chamfer.

[0012] Furthermore, the conical filter screen is a stainless steel conical filter screen.

[0013] Furthermore, the activated carbon filter element is medical activated carbon.

[0014] Furthermore, the supporting structure is a frame-like structure made of PTFE.

[0015] Beneficial effects:

[0016] The use of a disposable external gastric lavage filter connector greatly reduces the difficulty of cleaning, saving cleaning personnel considerable time and energy, and avoiding the risk of cross-infection due to incomplete connector cleaning. The medical-grade activated carbon filter element is the only adsorbent on the market capable of removing 100% of residual chlorine, and is highly effective in removing both chlorine-containing disinfectants and peracetic acid. This external gastric lavage filter connector effectively removes both substances, safeguarding the health and well-being of residents and medical staff. The conical filter screen, designed with a conical funnel, increases the filtration area, resulting in faster, higher, and better filtration, while also minimizing filter clogging.

[0017] Specifically, the advantages include:

[0018] Disposable design: The filter connector is for one-time use and does not require repeated cleaning and disinfection, avoiding the risk of cross infection. It is easy to operate and safe to use.

[0019] High-efficiency filtration: The use of medical-grade activated carbon materials and conical structure design significantly improves the filtration efficiency and can effectively remove harmful substances in gastric lavage fluid.

[0020] Stable structure: The support structure ensures the stability of the filter screen and conical filter screen, and will not deform or fall off during use.

[0021] Environmentally friendly materials: The shell and filter are made of environmentally friendly materials. After use, they can be recycled through professional channels, which meets modern environmental protection requirements.

[0022] Through the above structural design and working principle, the present invention provides an efficient, safe and environmentally friendly disposable external gastric lavage machine filter connector, which can effectively solve many problems in the existing technology, improve the safety and convenience of the gastric lavage process, and has broad application prospects.

[0050] Other implementations are the same as the first specific implementation.

[0051] Working principle:

[0052] The gastric lavage machine interface is connected to the lower end nozzle. When the gastric lavage fluid enters the external filter connector through the gastric lavage machine, it first passes through the conical filter screen. The conical filter screen uses its unique conical structure and efficient filtering ability to initially remove larger particles of impurities in the liquid. Subsequently, the liquid passes through the medical activated carbon filter element to further adsorb and remove tiny harmful substances and impurities. Then, with the stable support of the support structure, the liquid flows to the upper filter screen. The filter screen further intercepts residual tiny particles with its fine mesh structure, ensuring that the filtered liquid meets safety and cleanliness standards. The filtered liquid is discharged from the upper end nozzle of the outer shell. The upper end nozzle is connected to the gastric lavage tube. After the entire filtration process is completed, the gastric lavage fluid flows out of the gastric lavage tube.

[0053] Variations and Alternatives

[0054] The design of the disposable external gastric lavage machine filter connector of the present invention can be modified and replaced according to specific needs. For example:

[0055] Filter material replacement: The filter material can be replaced according to different usage environments and needs, such as using more efficient nanomaterials or other materials with better biocompatibility.

[0056] Improved shell shape: The shell shape can be adjusted according to different gastric lavage machine models to ensure better compatibility and sealing.

[0057] Multi-layer filter design: Add multiple layers of filter screens to the existing structure to improve filtering accuracy and efficiency.
