Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a disposable ventilator condensate collection component. Background Technology

[0002] When using existing ventilators, a traditional Y-shaped condenser cup is typically suspended between the two ends of the tubing, and the Y-shaped condenser cup must always be at the lowest point of the tubing.

[0003] However, in actual clinical practice, the Y-type condenser cup does not have a dedicated gas-liquid separation structure. The condensate collection efficiency is low and it is easily affected by the tube position, which can lead to condensate leakage or accumulation in the tube. This can affect respiratory mechanics monitoring and lead to unplanned respiratory support, or even cause condensate backflow, resulting in serious airway risks and increasing the possibility of ventilator-associated pneumonia. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a disposable ventilator condensate collection component to solve the above problems.

[0005] The technical solution of this utility model is as follows: a disposable ventilator condensate collection component includes a tube body, which is inverted Ω shape, including a connection port one and a connection port two located at its two ends, and an arc-shaped connecting part connecting the connection port one and the connection port two.

[0006] The arc-shaped connection includes:

[0007] Curved pipe;

[0008] A water collection container has an opening at its upper end and is located below an arc-shaped pipe. The lower end of the arc-shaped pipe is connected to an extension that extends into the opening and engages with the water collection container.

[0009] The curved pipe also includes:

[0010] The water inlet is located along the length of the arc-shaped pipe at the lower edge of the inner wall of the arc-shaped pipe, with one end extending downwards to the lower end of the extension.

[0011] A water-permeable but air-impermeable layer covers the upper edge of the water inlet to seal it and forms a condensate collection area between it and the bottom of the water collection container.

[0012] Furthermore, the water collection container includes a mounting portion that mates with the extension portion and a water collection portion connected to the lower end of the mounting portion, with the opening located at the upper end of the mounting portion. The water collection portion is a flexible water collection bag.

[0013] Furthermore, the inner edge of the opening of the mounting part is adapted to and sealed to the outer contour of the extension part.

[0014] Furthermore, the mounting section has through slots on both sides, and the extension section has hooks on both sides that cooperate with the slots.

[0015] Furthermore, the water-permeable but air-impermeable layer is a PES hydrophilic membrane.

[0016] Furthermore, the permeable opening is an arc-shaped, elongated strip.

[0017] Furthermore, both connection port one and connection port two have annular slots on their radially outer sides.

[0018] Furthermore, a drain outlet is provided on one side of the lower end of the flexible water collection bag.

[0019] Furthermore, the flexible water collection bag is made of transparent material, and water level markings are provided on its outer side.

[0020] The beneficial effects of this utility model are as follows:

[0021] The tube body adopts an inverted Ω-shaped structure, which, combined with the weight of the tube body itself, allows the arc-shaped connection part to be effectively kept at the lowest position in the ventilator tubing. This makes it less susceptible to external factors when condensate is automatically collected, solving the problem that traditional condenser cups are easily affected by the tube position.

[0022] The arc-shaped pipe, water collection container, and extension form an integrated collection structure with high integration and structural stability, providing a stable carrier for condensate collection.

[0023] A water-permeable opening is made on the lower edge of the inner wall of the arc-shaped pipe and covered with a water-permeable but air-impermeable layer to achieve gas-liquid separation that is water-permeable but air-impermeable. The condensate can flow smoothly into the collection area, and the ventilator gas can flow normally, which can efficiently collect the condensate.

[0024] The water inlet extends to the lower end of the extension section to ensure that condensate is completely directed into the water collection container without any residue in the pipes. Attached Figure Description

[0034] The arc-shaped connecting part 4 includes:

[0035] Curved pipe 401;

[0036] The water collection container 402 has an opening at its upper end and is located below the arc-shaped pipe 401. The lower end of the arc-shaped pipe 401 is connected to an extension 403 that extends into the opening and engages with the water collection container 402.

[0037] The curved pipe 401 also includes:

[0038] The water inlet 404 is opened along the length of the arc-shaped pipe 401 at the lower edge of the inner wall of the arc-shaped pipe 401, and one end extends downward through the lower end of the extension 403.

[0039] A water-permeable but air-impermeable layer 405 covers the upper edge of the water inlet 404 to seal the water inlet 404 and forms a condensate collection area between it and the bottom of the water collection container 402.

[0040] In the above technical solution, in order to ensure structural strength, the connection port 1 2, the connection port 2 3, the arc-shaped pipe 401 and the extension 403 are integrally injection molded;

[0041] By adopting the above technical solution, the tube body adopts an inverted Ω-shaped structure. Combined with the weight of the tube body itself, the arc-shaped connection part can be effectively kept at the lowest position of the ventilator tubing. When the condensate is automatically collected, it is not easily affected by external factors, thus solving the problem that traditional condenser cups are easily affected by the position of the tube.

[0042] Secondly, the arc-shaped pipe, water collection container, and extension form an integrated collection structure with high integration and structural stability, providing a stable carrier for condensate collection.

[0043] A water-permeable opening is made on the lower edge of the inner wall of the arc-shaped pipe and covered with a water-permeable but air-impermeable layer to achieve gas-liquid separation that is water-permeable but air-impermeable. The condensate can flow smoothly into the collection area, and the ventilator gas can flow normally, which can efficiently collect the condensate.

[0044] The water inlet extends to the lower end of the extension section to ensure that condensate is completely directed into the water collection container without any residue in the pipes.

[0048] Furthermore, the inner edge of the opening of the mounting portion is adapted to and sealed to the outer contour of the extension portion 403;

[0049] In the above scheme, specifically, the mounting part is an arc-shaped kit that adapts to the outer contour of the extension part 403. The mounting part is integrally injection molded, and the opening is set through the mounting part from top to bottom. The water collection bag can be connected and fixed to the mounting part by hot melt bonding. In addition to being a flexible water collection bag, the water collection part can also be a rigid water collection box, preferably a flexible water collection bag.

[0050] By adopting the above technical solution, the inner edge of the installation opening and the outer contour of the extension are matched and sealed to ensure the airtightness of the connection, prevent gas leakage and condensate from seeping from the gap, avoid affecting respiratory mechanics monitoring, and improve the safety of use.

[0051] By using a water collection bag, the weight of the pipe can be reduced appropriately, preventing the pipe from bending under pressure after the condensate fills up.
