[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1-2 As shown, a multifunctional spraying and alveolar lavage catheter includes a main catheter 1, the rear side of which is connected to a branch catheter 2. The main catheter 1 is responsible for the delivery path of the liquid medicine. The main catheter 1 is connected to the branch catheter 2, and spraying or alveolar lavage is performed at the front end, so that the spraying and alveolar lavage functions can be completed in an integrated manner. The function of the branch catheter 2 is to provide multiple channels, different channels can be used for delivery separately, and sputum suction operations can be performed at the same time. The branch catheter 2 increases versatility and reduces the trouble of catheter replacement.

[0022] The front end of the main catheter 1 is provided with a membrane 5 with spray holes 6. The membrane 5 is installed at the front end of the main catheter 1. It is soft and conformable. The spray holes 6 in the membrane 5 ensure uniform spraying of the target area, and the soft material reduces patient discomfort. Tear holes 7 are provided on the top and outside of the membrane 5. These holes are distributed on the outside of the top of the membrane 5, making it easy for medical staff to quickly remove the membrane 5 for subsequent spraying operations.

[0023] The following is a detailed description of the design of the above key components:

[0024] Two branch catheters 2 are connected to the rear side of the main catheter 1 via a tee, forming a Y-shaped connection with the main catheter 1. This Y-shaped structure allows for separate delivery of different functions, such as one catheter for spraying and another for alveolar lavage, avoiding mixing and cross-contamination of drug solutions, while also reducing the number of catheter replacement steps and simplifying the operation process.

[0025] The branch catheters 2 are provided with connecting sleeves 3, each equipped with a switch knob 4. The number of connecting sleeves 3 corresponds to the number of branch catheters 2. Each branch catheter 2 has an independent connecting sleeve 3, each equipped with a switch knob 4. Medical personnel can precisely control the opening and closing of each branch catheter 2 by rotating the switch knob 4. The spraying and irrigation functions can be flexibly switched without changing the catheter, reducing the risk of misoperation and improving operational convenience.

[0026] The sheath 5 is made of soft silicone, with a diameter ≤ the diameter of the main catheter 1. The soft silicone material offers excellent flexibility and biocompatibility, effectively reducing patient discomfort while ensuring the catheter's flexibility and tightness during use. Furthermore, the soft silicone material of the sheath 5 effectively reduces mucosal scratches and bleeding caused by manipulation.

[0027] The diameter of the mantle 5 is designed to be no larger than the diameter of the main catheter 1. This design ensures smooth operation of the mantle 5 and avoids blocking the trachea.

[0028] The tear holes 7 are evenly and densely distributed around the top outer side of the mantle 5. This design allows medical personnel to quickly and easily tear the mantle 5 when subsequent irrigation procedures are required, reducing operation time and steps. This even and dense distribution ensures that the mantle 5 can be torn smoothly throughout the entire operation without causing localized excessive stretching or tearing.

[0029] A color mark 8 is provided on the outer side of the sleeve 5 at the location of the tear hole 7. The color mark 8 is provided on the outer side of the tear hole 7 as a visual cue to help medical staff quickly locate the location of the tear hole 7, thereby improving the intuitiveness and accuracy of operation. Especially in emergency situations, it helps to reduce the probability of misoperation and improve the safety and efficiency of operation.

[0030] Note: This product is a one-time use product and must be discarded as medical waste after use and cannot be reused.

[0031] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology and will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
