Description

Technical Field

[0001] This utility model relates to the field of breathing tubes, and in particular to an exhaust sheet for breathing tubes. Background Technology

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation, are widely used in respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, occupying a very important position in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.

[0003] The ventilator tubing serves as the gas passage between the ventilator and other connecting devices such as artificial airways or masks. It is an important connection channel to ensure that the ventilator delivers air into the lungs and that air is expelled from the lungs. When connecting the ventilator tubing to the ventilator and artificial airways or masks, connectors are often used as a connection medium to facilitate the connection between the ventilator tubing and the ventilator and artificial airways or masks.

[0004] Some breathing tubes have vents to prevent negative pressure in the breathing channel, which could affect the smoothness of inhalation and exhalation. However, existing vents are located on arc-shaped structures (such as ovals or semicircles).

[0005] In practice, industry standards generally require three rows with eight holes per row. However, the actual number of holes and rows can be adjusted according to specific needs.

[0006] However, when directly molding the holes in the arc-shaped plastic structure, it is necessary to use molding pins distributed along the axis for integral injection molding (radial distribution, i.e., current products on the market cannot achieve venting outward from the center of the pipeline due to mold technology issues). Therefore, the gap between the ends of the molding pins is small, so the ejector pin structure of the mold requires high precision, resulting in higher production costs, poor stability and durability, and affecting the production efficiency of the product.

[0007] Of course, there are also structures that form the breathing tube first, and then laser-form it after precision drilling. In that case, the equipment cost and production process are longer. Also, as a medical product, the breathing tube has high hygiene requirements, so it also needs to be professionally cleaned. Therefore, the unit cost is higher, which affects production efficiency. Utility Model Content

[0008] The main purpose of this invention is to propose an exhaust sheet for a breathing tube, which aims to form holes while the sheet is horizontally formed, and then bend the horizontal sheet and integrally injection molded with the breathing tube, thereby reducing the difficulty of hole forming, while ensuring stable hole arrangement accuracy, effectively reducing production costs, and thus improving market competitiveness.

[0009] To achieve the above objectives, this utility model proposes an exhaust sheet for a breathing tube, comprising:

[0010] The sheet material is horizontal and integrally formed with spaced-distributed vent holes.

[0011] The sheet has a deformation groove recessed on its wall surface, and the sheet can be bent and formed into an arc shape by using the deformation groove as a fulcrum.

[0012] In practical design, the sheet material is first formed into a horizontal structure in the mold, while the ejector pins are parallel to each other and integrally formed with the horizontal sheet material. This ensures consistent spacing between the vent holes, resulting in stable vent hole forming accuracy. Furthermore, the mold structure is simple, effectively improving production efficiency.

[0013] Meanwhile, the deformation groove allows the sheet material to be bent at a fulcrum during secondary injection molding, and then filled with glue into a round or elliptical tubular structure during the second injection molding process. Finally, it can be integrally molded with a hose or installed detachably.

[0014] This structure effectively ensures that the spacing between the exhaust holes is consistent and that they are distributed at intervals along the axis of the connector, thus ensuring consistent flow pressure in the breathing tube. This effectively reduces exhaust noise and improves product stability. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0029] like Figures 1 to 7 As shown, an exhaust sheet for a breathing tube includes:

[0030] The sheet material is horizontal and integrally formed with spaced-distributed vent holes.

[0031] The sheet has a deformation groove recessed on its wall surface, and the sheet can be bent and formed into an arc shape by using the deformation groove as a fulcrum.

[0032] In practical design, the sheet material is first formed into a horizontal structure in the mold, while the ejector pins are parallel to each other and integrally formed with the horizontal sheet material. This ensures consistent spacing between the vent holes, resulting in stable vent hole forming accuracy. Furthermore, the mold structure is simple, effectively improving production efficiency.

[0033] Meanwhile, the deformation groove allows the sheet material to be bent at a fulcrum during secondary injection molding, and then filled with glue into a round or elliptical tubular structure during the second injection molding process. Finally, it can be integrally molded with a hose or installed detachably.

[0034] This structure effectively ensures that the spacing between the exhaust holes is consistent and that they are distributed at intervals along the axis of the connector, thus ensuring consistent flow pressure in the breathing tube and improving the stability of the product.

[0035] Specifically, the arc-shaped piece is semi-arc or semi-circular, and the shape of the deformation groove can be designed according to the actual shape of the breathing tube, with the deformation groove as the fulcrum for bending.

[0036] In this embodiment of the invention, the deformation groove is thin-walled, meaning that in terms of microstructure, the thickness at this location is less than the thickness at the location where the vent hole is located, thereby achieving the function of fulcrum deformation.

[0037] Specifically, the sheet is a rigid material, and the breathing tube includes a flexible tube and a rigid interface. The sheet portion is the connector, so this part is made of rigid material to prevent the sheet from deforming during breathing and causing blockage of the passage.

[0038] In this embodiment of the invention, the deformation groove is recessed into the inner wall and / or outer wall of the sheet. For example... Figure 1 as well as Figure 5 The upper and lower walls shown are preferably formed on the inner wall.

[0039] Specifically, the deformation groove is provided on the inner wall of the sheet, and its cross-section is triangular. The triangular shape can make the gap between the arc-shaped sheets smaller and improve the fit between the deformation grooves.

[0040] In this embodiment of the utility model, the deformation groove is provided in a group or spaced apart between the two exhaust holes, wherein the spaced arrangement can further ensure that the spacing between the two exhaust holes is consistent.

[0041] Specifically, the sheet is formed by mechanical bending or hot bending. In actual design, mechanical bending is preferred. For this type of rigid plastic material, hot bending will cause changes in the structure (especially changes in the inner diameter of the vent holes), which will affect the product quality.

[0042] In this embodiment of the utility model, the arc-shaped piece and the connector are formed by secondary injection molding.

[0043] Specifically, the connector is also connected to a flexible hose.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
