The embodiment of the application discloses a device for lung expansion.

Referring to fig. 1, an embodiment of a device for inflating a lung provided in an embodiment of the present application includes:

a bronchofiberscope 100, a connector 300, and a respiratory balloon 200.

The bronchofiberscope 100 and the respiration balloon 200 are both of an existing structure, and the respiration balloon 200 may be a simple respiration balloon for children, and the like, which is not described herein again. One end of the connector 300 is connected to the air outlet of the respiratory balloon 200, and the other end is connected to the air injection port of the bronchofiberscope 100, so as to connect the air outlet of the respiratory balloon 200 to the air injection port of the bronchofiberscope 100.

The new lung expansion device is constructed by matching the bronchofiberscope 100 and the breathing saccule 200, so that the specific lung segment can be quickly and accurately expanded in about 1 minute without equipment such as a high-frequency jet respirator, and the device is simple, easy to implement and capable of accurately identifying the inter-segment plane. Compared with the traditional expansion collapse method, the method can shorten the operation and anesthesia time of more than ten minutes, and is beneficial to the rapid recovery of the patient; and medicines and equipment such as a fluorescent endoscope and a fluorescent tracer are not needed, so that the expenditure of patients and the investment of medical equipment are reduced. The oxygen supply device can also be used for oxygen supply to specific lung sections and lung lobes, can provide operation opportunities for patients with poor lung function and needing single lung ventilation in the operation, ensures the safety in the operation, can correct the imbalance of ventilation and blood flow of the patients with poor lung function and needing the single lung ventilation in the operation, and prevents and improves hypoxemia in the operation.

The above is an embodiment one of the lung inflating device provided in the embodiments of the present application, and the following is an embodiment two of the lung inflating device provided in the embodiments of the present application, please refer to fig. 1 to 2 specifically.

The scheme based on the first embodiment is as follows:

further, as shown in fig. 2, the connector 300 includes a connector body 1 and a connecting pipe 2. One end of the connector body 1 forms a first joint 11; the first connector 11 is detachably inserted and matched with the air outlet of the respiration sacculus 200; the other end of the connector body 1 forms a second joint 12. The connecting conduit 2 is sleeved on the second joint 12, and part of the connecting conduit extends out of the second joint 12; the portion of the connection tube 2 protruding out of the second joint is detachably fitted to the gas-injection port of the bronchofiberscope 100 by plugging. Specifically, the connecting conduit 2 of the connector 300 is made of PVC, and the connector body 1 is made of polypropylene. The connecting duct 2 has an outer diameter of 4.3mm and an inner diameter of 3.0mm. The first joint 11 of the connector body 1 has an outer diameter of 15mm and an inner diameter of 12mm, and the gas outlet of the respiration balloon 200 and the gas injection port of the bronchofiberscope 100 can be better connected by the design.

Furthermore, an integrally formed flange 13 is annularly arranged on the outer peripheral surface of the connector body 1, and a plurality of circumferentially uniformly distributed recesses are arranged on the flange 13. The flange 13 of this design provides a convenient grip for the user, and facilitates the user to manipulate the connector 300 to connect to the bronchoscope 100 and the respiratory balloon 200 by grasping the flange 13 structure.

In the case of the connector 300, it can be prepared by cutting a 3.0 # endotracheal tube, and specifically, in the case of the connector body 1, it is a structural portion of the endotracheal tube that can be fitted with the outlet port of the respiration balloon 200. In the case of the connecting tube 2, it is a tube segment of the endotracheal tube cut by a pair of sterilizing scissors. Care should be taken to trim the end of the tube smooth and burr-free during the tube cutting of the endotracheal tube to avoid small plastic drops in the working channel of the bronchofiberscope 100 and even in the patient. The connector 300 of the embodiment is simple and easy to design, can be prepared by cutting a 3.0 # tracheal cannula, is low in cost and is convenient for subsequent popularization.

Further, taking the above-described structural design of this connector 300 as an example, the length L of the pipe section of the connecting conduit 2 extending out of the second joint 12 may be 7mm. Specifically, if the length of the connecting conduit 2 extending out of the second connector 12 is too long, and the connecting conduit is detachably inserted into the gas injection port of the bronchofiberscope 100, a longer conduit section is left between the gas injection port and the respiration balloon 200, and since the gas injection port of the bronchofiberscope 100 is small in diameter and the whole gas injection channel is long and narrow, the anatomical void cavity is further increased, the gas injection resistance is increased, and the longer conduit is easily bent and folded. If the length of the pipe section extending out of the second connector 12 is short or the connection pipe 2 is not provided directly, the connector body 1 is inserted into the gas injection port too short, so that the entire connector 300 and the gas injection port are not connected tightly enough and are easy to fall off, and the operation of the respiration balloon 200 is not convenient. Therefore, researches show that when the length of the pipe section of the connecting conduit 2 extending out of the second joint 12 is 7mm +/-1 mm, the connecting conduit can be tightly connected with the air injection port and is not easy to fall off, the respiration balloon 200 can be operated well, and meanwhile, the increase of an anatomical invalid cavity and air injection resistance and the bending and folding of the connecting conduit 2 can be avoided as much as possible.

In addition, as for the design of the connector 300, the connector can also comprise a 5ml syringe barrel, namely, the existing 5ml syringe barrel is directly selected for use, the small-diameter end of the syringe barrel is inserted into the gas injection port of the bronchofiberscope 100, and the other end of the syringe barrel is tightly connected with the respiratory balloon 200 by winding adhesive tape. The connection between the respiration sacculus 200 and the bronchofiberscope 100 can be realized by the design method, and of course, other connection structures can be designed according to actual needs to realize the connection between the respiration sacculus 200 and the bronchofiberscope 100.

While the present application provides a device for lung inflation, it will be appreciated that those skilled in the art may still further adapt the concepts of the embodiments of the present application without departing from the scope and spirit of the present application.
