Problems solved by technology

[0003] Among them, the catheter suction operation needs to be realized with the help of the sputum suction catheter. The sputum suction catheter used in the prior art is mainly composed of a catheter and a connector for connecting a sputum suction device or a negative pressure suction device. Its structure and function are very simple. In the actual operation of sputum suction, when the catheter is inserted into the patient's respiratory tract, it often occurs that the catheter strays into the esophagus, causing discomfort such as nausea and vomiting, which virtually increases the psychological pressure on the patient and makes the patient more resistant. It is difficult and cumbersome for medical staff to perform sputum suction operation, time-consuming and labor-intensive, so it is necessary to improve the existing sputum suction catheter

Embodiment 1

[0028] refer to figure 1 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , a sputum suction catheter for thoracic surgery nursing, comprising a catheter 1 and a connector 2 installed with one end of the catheter 1, the end of the connector 2 away from the catheter 1 is externally connected with a negative pressure suction device or a sputum suction device, and the outer wall of the catheter 1 is covered A sleeve 3 is provided, which is a double-layer structure. The sleeve 3 includes an inner tube 302 and an outer tube 301. The sleeve 3 is sleeved on the outside of the catheter 1 through the inner tube 302. The inner tube 302 and the outer tube 301 previously existed The cavity 303, the two ends of the inner tube 302 and the outer tube 301 are closed, and the end of the outer tube 301 of the casing 3 near the connector 2 is installed with a connecting pipe 4, and the first valve 402 is installed on the connecting pipe 4, and the connecting pipe 4 A pressurizatio...

Embodiment 2

[0038] refer to figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The difference between the second embodiment and the first embodiment is that the pressurizing mechanism is the water injection syringe 403, and the water injection syringe 403 is connected with the communication pipe 4, and the small water bag 5 is injected with water through the water injection syringe 403.

[0039]The working principle and process of Embodiment 1 and Embodiment 2 are as follows: when the catheter 1 is inserted, the cannula 3 and the small water bladder 5 can follow the catheter 1 to move, and after reaching a certain depth, inject liquid through the large water bladder 401 or the water injection syringe 403 , the liquid enters the gap between the inner tube 302 and the outer tube 301 of 3 through the connecting tube 4, and finally enters the small water bag 5, and makes the small water bag 5 expand, and the expanded small water bag 5 continues to move down and expand T...

Abstract

The invention discloses a sputum suction catheter for thoracic surgery nursing. The catheter comprises a catheter body and a connector installed at one end of the catheter body. One end, far away fromthe catheter, of the connector is connected with a negative pressure aspirator or a sputum aspirator; the outer side wall of the catheter is sleeved with a sleeve. The sleeve has a double-layer structure and comprises an inner pipe and an outer pipe, the sleeve is arranged on the outer side of the catheter in a sleeving mode through the inner pipe, a cavity exists between the inner pipe and the outer pipe, the two ends of the inner pipe and the two ends of the outer pipe are closed, a communicating pipe is installed at the end, close to the connector, of the outer pipe of the sleeve, and a first valve is installed on the communicating pipe. The sleeve is arranged on the outer side of the catheter; meanwhile, an expandable small water bag is used for blocking the esophageal opening of a patient, the catheter can be prevented from accidentally entering the esophageal opening in the process of entering the respiratory tract, the discomfort feeling such as vomiting, nausea, and the like is avoided, the user experience of the patient during sputum suction is improved, and the catheter is more easily accepted by the patient.

Description

technical field [0001] The invention relates to the technical field of thoracic surgery nursing, in particular to a sputum suction catheter for thoracic surgery nursing. Background technique [0002] Respiratory care is the focus of postoperative care in thoracic surgery. Nebulization should be strengthened, sit up and pat your back, stimulate the carina, encourage expectoration, and if necessary, perform catheter suction or bronchoscope suction to discharge respiratory secretions in time and promote lung expansion , according to the condition, give catheter oxygen supply or mask oxygen supply. [0003] Among them, the catheter suction operation needs to be realized with the help of the sputum suction catheter. The sputum suction catheter used in the prior art is mainly composed of a catheter and a connector for connecting a sputum suction device or a negative pressure suction device. Its structure and function are very simple. In the actual operation of sputum suction, whe...
