Description

Technical Field

[0001] The utility model relates to the technical field of breathing circuits, and specifically relates to a disposable cover for a breathing circuit. Background Art

[0002] The breathing circuit connector is mainly used on anesthetic machines and ventilators to deliver the gas output by the anesthetic machine and the ventilator to the tracheal intubation or anesthetic mask, and can also deliver the gas exhaled by the tracheal intubation to the anesthetic machine or the ventilator for recirculation or discharge.

[0003] The covers on the breathing circuit are generally arranged on the breathing circuit connectors to prevent exposure to the air before use on patients, thus preventing contamination. However, the traditional breathing circuit covers are relatively inconvenient to disassemble, and the current round-hole covers made of plastic material are too thick and the material is too hard in clinical use, increasing the frictional resistance and causing inconvenience. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a disposable cover for a breathing circuit to solve the problems mentioned in the above background art, that is, the covers on the breathing circuit are generally arranged on the breathing circuit connectors to prevent exposure to the air before use on patients, thus preventing contamination. However, the traditional breathing circuit covers are relatively inconvenient to disassemble, and the current round-hole covers made of plastic material are too thick and the material is too hard in clinical use, increasing the frictional resistance and causing inconvenience.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A disposable cover for a breathing circuit, including a breathing circuit main body, a cover main body is installed at the upper end of the breathing circuit main body, a first fastening belt is fixedly installed on one side end face of the cover main body, a plurality of positioning holes are opened on the first fastening belt, and the plurality of positioning holes are linearly arrayed on the first fastening belt. A second fastening belt is fixedly installed at the other end of the cover main body, a raised block is fixedly installed at a position closer to the bottom on the inner end face of the second fastening belt, a rubber sealing ring is arranged at the inner end of the cover main body, and the material used for the cover main body is PVC material.

[0006] Adopting the above technical solution, by installing the cover body onto the breathing circuit body, then winding the first fastening belt and the second fastening belt around the breathing circuit body, and then inserting the raised block installed at the inner end of the second fastening belt into the positioning hole opened on the first fastening belt, the stability of the cover body can be improved after the cover body is installed onto the breathing circuit body. Then, due to the positioning holes arranged in a linear array on the first fastening belt, it can be better adjusted at the connection between the first fastening belt and the second fastening belt. Then, when it is necessary to disassemble the cover body for replacement, the raised block can be taken out from the positioning hole, so that the first fastening belt and the second fastening belt cancel the restriction on the cover body. The rubber sealing ring arranged in the cover body can better prevent gas leakage. At the same time, the material used for the cover body is PVC material, and the price of PVC material is relatively cheap. Therefore, the overall price of the cover body is also relatively cheap, which is convenient for the staff to use it disposable.

[0007] Preferably, a raised plate is fixedly installed on one end face of the cover body, and a through hole is opened at the top end of the cover body.

[0008] Adopting the above technical solution, by the medical staff pulling up the raised plate, the cover body can be easily removed from the breathing circuit.

[0009] Preferably, a connecting belt is fixedly installed on the rear end face of the cover body, an installation plate is fixedly installed on the connecting belt, and anti-slip layers are arranged on both end faces of the installation plate.

[0010] Adopting the above technical solution, the anti-slip layers arranged on both sides of the installation plate facilitate the staff to drive the installation plate to pull out the insertion block from the through hole, thus preventing the occurrence of slipping.

[0011] Preferably, a sealing plate is fixedly installed at the bottom of the installation plate, a connecting column is fixedly installed at the bottom of the sealing plate, an insertion block is fixedly installed at the bottom of the connecting column, the shape of the insertion block is conical, and a fillet is arranged at the upper edge position of the insertion block.

[0012] Adopting the above technical solution, since a fillet is arranged at the upper edge position of the insertion block, when the medical staff pulls out the insertion block from the through hole, it will not generate a large resistance. Therefore, the insertion block can be better pulled out from the through hole. Then, the sealing plate arranged at the bottom of the installation plate can perform secondary sealing on the through hole on the cover body, so as to better prevent bacteria from entering the breathing circuit body and causing infection in the breathing circuit body.

[0013] Preferably, the material used for the insertion block is silicone rubber material.

[0014] With the above technical solution, since the material used for the insertion block is silicone rubber, the insertion block has good plasticity, so that the insertion block can be better withdrawn from the through hole.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. For the disposable cover for the breathing circuit, by installing the cover body onto the breathing circuit body, then winding the first fastening band and the second fastening band around the breathing circuit body, and then inserting the raised block installed at the inner end of the second fastening band into the positioning hole opened on the first fastening band, the stability of the cover body can be improved after the cover body is installed onto the breathing circuit body. And because the positioning holes are arranged in a linear array on the first fastening band, the connection between the first fastening band and the second fastening band can be adjusted well.

[0017] 2. For the disposable cover for the breathing circuit, the upper edge position of the insertion block is provided with a rounded corner, so that when medical staff withdraw the insertion block from the through hole, there will be no great resistance, and the insertion block can be better withdrawn from the through hole. Then, the sealing plate arranged at the bottom of the mounting plate can perform secondary sealing on the through hole on the cover body, so as to better prevent bacteria from entering the breathing circuit body and causing infection in the breathing circuit body.
