Description

Technical Field

[0001] The utility model relates to the technical field of medical gas supply, in particular to a medical gas terminal plug. Background Technique

[0002] At present, gas equipment belts are usually equipped on the indoor walls of medical institutions. Medical gas terminals are loaded on the gas equipment belts to provide medical gas for medical equipment that needs to connect to a gas source, such as providing oxygen for a ventilator. The medical equipment that needs to connect to the gas source is connected to the medical gas terminal through a hose. When in use, the medical gas terminal plug installed at one end of the hose is inserted into the medical gas terminal socket on the wall to connect the hose to the medical gas terminal, and the medical gas terminal supplies the required medical gas to the medical equipment through the hose.

[0003] The manufacturing standards of medical gas terminals are usually divided into multiple standards such as national standard, German standard, American standard, Japanese standard, Korean standard, French standard, etc. In a large medical institution, the medical gas terminals equipped in each building and each department usually have different standards due to different construction and decoration times. The socket shapes of medical gas terminal sockets with different standards are different; even if the equipped medical gas terminals have the same standard, the socket shapes of medical gas terminal sockets with the same standard will also have slight differences due to different brands and production batches. Therefore, when the medical equipment that needs to connect to the gas source is transferred and used among different departments, the medical gas terminal plug usually cannot be inserted into the medical gas terminal socket, or after being inserted into the medical gas terminal socket, gas leakage, loose gas source interface and other situations may occur due to different standards of the medical gas terminal plug and the medical gas terminal socket, or the same standard but different brands and production batches, resulting in the medical equipment that needs to connect to the gas source being unable to be used normally, or there being potential medical safety hazards during use.

[0004] In view of the above situation, the traditional clinical solution is to replace the medical gas terminal plug on the hose. The engineer cuts off the original medical gas terminal plug on the hose and then fixes a medical gas terminal plug that exactly matches the socket shape of the medical gas terminal socket on the hose with a hose clamp. However, the medical gas terminal plug must be replaced by an engineer. When the socket shape of the medical gas terminal plug does not match that of the medical gas terminal socket, an engineer needs to be called temporarily for replacement, and it usually takes 5 to 15 minutes to replace the medical gas terminal plug. In an emergency, it may cause the medical gas not to be supplied to the medical device for a short time, resulting in medical safety risks. Another solution is to connect the medical gas terminal plug and the medical gas terminal socket through an adapter. Although the adapter is easy to install, one adapter can only connect a medical gas terminal plug of one specified standard to a medical gas terminal socket of another specified standard. If the medical gas terminal plug or the medical gas terminal socket is different from the standard specified by the adapter, another adapter needs to be replaced. Therefore, it is necessary to prepare various types of adapters according to the standards of the medical gas terminal plug and the medical gas terminal socket, and the unit price of the adapter is relatively high, and a large number of configurations will increase the use cost. Summary of the Invention

[0005] The purpose of the present invention is to provide a medical gas terminal plug to solve at least one of the above technical problems existing in the prior art.

[0006] To solve the above technical problems, a medical gas terminal plug provided by the present invention includes: a connection seat and medical gas source connectors of various standards;

[0007] The connection seat is arranged at one end of a hose for supplying medical gas to a medical device, and the medical gas source connector is connected to the hose through the connection seat;

[0008] One end of the connection seat is provided with a female quick connector structure, and one end of the medical gas source connector is provided with a male quick connector structure. The medical gas source connector is detachably connected to the female quick connector structure of the connection seat through the male quick connector structure, and the medical gas source connector can be quickly connected to or separated from the connection seat;

[0009] When replacing the medical gas source connector, the medical gas source connector can be quickly unplugged from or inserted into the female quick connector structure of the connection seat through the male quick connector structure. The operation is simple and convenient, there is no need to cut the hose, and the medical gas source connector can be reused, thus avoiding waste of resources and having a lower use cost;

[0010] The other end of the medical gas source connector is provided with a medical gas terminal plug structure for connecting to a medical gas terminal socket of a corresponding standard. When in use, it is inserted into the medical gas terminal socket of the corresponding standard to connect the hose to the medical gas terminal. Then, the medical gas terminal supplies the required medical gas to the medical device through the hose;

[0011] In the case where the medical gas terminal plug structure of the medical gas source connector does not match the socket shape of the medical gas terminal socket, there is no need to call an engineer. Medical staff can quickly replace the medical gas source connector within 5 seconds, making the medical gas terminal plug structure of the medical gas source connector completely match the socket shape of the medical gas terminal socket, ensuring that the medical device that needs to be connected to the gas source can be put into normal use at the fastest speed and avoiding potential medical safety risks.

[0012] In this application, a quick-connect female head structure is provided on the connection seat, and a quick-connect male head structure is provided on the medical gas source connector. The medical gas source connector can be quickly inserted onto or removed from the quick-connect female head structure of the connection seat through the quick-connect male head structure. The operation is simple and convenient. In the case where the medical gas terminal plug does not match the socket shape of the medical gas terminal socket, medical staff can quickly replace the medical gas source connector by themselves, thus greatly improving the replacement efficiency and avoiding potential medical safety risks.

[0013] Further, the quick-connect female head structure includes: a female head structure body and a sliding sleeve;

[0014] The sliding sleeve is slidably sleeved on the female head structure body for locking the quick-connect female head structure;

[0015] When the quick-connect male head structure is connected to the quick-connect female head structure, the sliding sleeve automatically or manually slides the sliding sleeve along the central axis of the female head structure body in a direction away from the quick-connect male head structure, inserts the quick-connect male head structure into the quick-connect female head structure, the sliding sleeve automatically or manually resets the sliding sleeve, and the quick-connect female head structure is locked by the sliding sleeve, fixing the quick-connect male head structure and the quick-connect female head structure, thereby connecting the medical gas source connector to the connection seat;

[0016] When the male structure of the quick connector is separated from the female structure of the quick connector, the sliding sleeve automatically or manually slides the sliding sleeve along the body of the female structure away from the male structure of the quick connector, pulling out the male structure of the quick connector from the female structure of the quick connector, thereby pulling out the medical gas source connector from the connection seat. After pulling out the male structure of the quick connector, the sliding sleeve automatically or manually resets the sliding sleeve, and the female structure of the quick connector is locked by the sliding sleeve.

[0017] Furthermore, a pin structure is provided on the female structure of the quick connector. The pin structure includes: a pin head and a pin hole;

[0018] The pin head is provided on the body of the female structure;

[0019] The pin hole is provided on the sliding sleeve;

[0020] The sliding sleeve can rotate circumferentially along the body of the female structure. By rotating the sliding sleeve, the pin hole is misaligned with the pin head, and the sliding sleeve abuts against the pin head and cannot slide. Furthermore, the female structure of the quick connector is always locked, and the medical gas source connector cannot be separated from the connection seat in the connected state;

[0021] When the pin hole on the sliding sleeve is aligned with the pin head on the body of the female structure, the sliding sleeve can slide axially along the body of the female structure, and the male structure of the quick connector can be connected to or separated from the female structure of the quick connector. Thus, the medical gas source connector can be inserted into or pulled out from the connection seat;

[0022] When the pin hole on the sliding sleeve is misaligned with the pin head on the body of the female structure, the sliding sleeve abuts against the pin head on the body of the female structure, and the sliding sleeve cannot slide along the central axis of the body of the female structure away from the male structure of the quick connector. The female structure of the quick connector is always locked, and the male structure of the quick connector cannot be inserted into or pulled out from the female structure of the quick connector. Thus, the medical gas source connector cannot be inserted into or pulled out from the connection seat, preventing the medical gas source connector from being accidentally separated from the connection seat in the connected state and avoiding medical accidents.

[0023] Preferably, the male structure of the quick connector is the male structure of a self-locking quick connector, and the female structure of the quick connector is the female structure of a self-locking quick connector, facilitating the quick connection or separation of the medical gas source connector from the connection seat.

[0024] Optionally, the quick connector male structure is connected to the medical gas terminal plug structure by welding or threading;

[0025] Of course, the quick connector male head structure and the medical gas terminal plug structure may also be an integrated component.

[0026] Furthermore, the medical gas source connectors of various standards are provided with the medical gas terminal plug structures of corresponding standards;

[0027] The medical gas terminal plug structure includes: a national standard medical gas terminal plug structure, a German standard medical gas terminal plug structure, a Hong Kong standard medical gas terminal plug structure, an American standard medical gas terminal plug structure, a Japanese standard medical gas terminal plug structure and a Korean standard medical gas terminal plug structure;

[0029] Furthermore, a first annular structure is provided on the connecting seat, and a second annular structure is provided on the medical gas source connector. The first annular structure and the second annular structure are connected via a flexible connecting component, and then the connecting seat and the medical gas source connector are connected via the flexible connecting component.

[0030] Furthermore, the connection seat is connected to one or more medical gas source connectors of different standards through the flexible connection component, which facilitates the screening and taking of the medical gas source connectors corresponding to the standard of the medical gas terminal socket, reduces the time required for screening and taking of the medical gas source connectors of the corresponding standard, further improves the replacement efficiency, and avoids medical safety risks;

[0031] The number of standard types of the medical gas source connectors to which the connecting socket is connected via the flexible connecting component is determined according to the number of standard types of medical gas terminal sockets provided on the indoor walls of the medical institution.

[0032] Preferably, the flexible connecting member is a thin chain or a rope made of other flexible material.
