Description

Technical Field

[0001] This application relates to the field of medical devices, and particularly to a multi-functional catheter. Background Art

[0002] In clinical anesthesia work, for establishing an artificial airway to manage respiration in difficult airways, the awake tracheal intubation technique is commonly used at present.

[0003] Awake tracheal intubation refers to performing tracheal intubation after topical anesthesia of the airway while the patient is awake and retains spontaneous respiration, which can establish a good airway before general anesthesia induction and avoid potential risks and poor prognosis caused by ventilation difficulties in the patient after anesthesia.

[0004] Awake tracheal intubation is preferably performed in the operating room and under routine vital sign monitoring because local anesthetics and sedative drugs used may interfere with heart rate and blood pressure. Clinically, end-tidal carbon dioxide is usually monitored, and an end-tidal carbon dioxide collection tube is required.

[0005] Although the patient's spontaneous respiration is retained during awake tracheal intubation, according to the data, the patient still has a risk of hypoxia. Therefore, it is recommended to perform pre-oxygenation before intubation, which requires an oxygen inhalation tube.

[0006] In addition, more importantly, before awake tracheal intubation, the doctor needs to first spray a sufficient amount of topical anesthetic on the patient's oral cavity and trachea, and then an experienced anesthesiologist can perform intubation. Currently, a spraying type dispenser is commonly used for airway topical anesthesia.

[0007] For establishing an artificial airway to manage respiration in difficult airways, a series of operations such as drug administration, oxygen supply, sputum suction, and collection need to be performed on the patient. Different tools are used for each step, and all the tools used need to be prepared. However, for different patients, the situations are different, and in some cases, some of these steps can be ignored to speed up the anesthesia progress.

[0008] The above series of operation specifications require medical staff to prepare various devices and catheters before performing intubation, which is very inconvenient, prone to omission, and time-consuming for preoperative preparation. Utility Model Content

[0009] The purpose of this application is to provide a multi-functional catheter for various operations before establishing an artificial airway during anesthesia, which can meet multiple functions such as airway drug administration, oxygen supply, sputum suction, and collection before anesthesia.

[0010] To solve the above technical problems, the following technical solutions are adopted:

[0011] In a first aspect, the present application provides a multi-functional catheter, including a main catheter, a horn interface, a sputum suction interface, an oxygen supply tube, and a sputum suction head. One end of the main catheter serves as a mechanical end, and the other end serves as a patient end. The mechanical end is detachably connected to the horn interface or the sputum suction interface, and the patient end is detachably connected to the oxygen supply tube or the sputum suction head to assemble catheters with different functions.

[0012] The mechanical end of the main catheter is connected to the horn interface through a Luer connector, and the patient end is connected to the oxygen supply tube through a Luer connector.

[0013] One end of the oxygen supply tube away from the main catheter is detachably connected to a spraying head.

[0014] The end of the spraying head away from the main catheter is provided with fine holes, and the fine holes enable the drug to be evenly sprayed onto the inner surface of the airway.

[0015] The catheter on the spraying head connected to the oxygen supply tube is curved.

[0016] The horn interface presents a horn shape. Its small diameter is connected to the mechanical end of the main catheter through a Luer connector, and its large diameter is used to connect to the device.

[0017] The sputum suction head is a flexible tube with multiple small holes on its tube wall.

[0018] The sputum suction interface is provided with a ventilation hole, and a plug body is provided on the sputum suction interface. The ventilation hole is opened and closed through the plug body.

[0019] Compared with the prior art, the beneficial effects achieved by the present application are as follows:

[0020] The multi-functional catheter provided by the present application can select a suitable connector according to the usage situation, including connectors with all functions. When in use, select the corresponding connector and install it on the main catheter for use. By configuring a multi-functional connector on one tube, multi-functional use is realized. The catheter connectors with multiple functions are aggregated into a catheter assembly, enabling multiple functions such as drug administration, oxygen supply, sputum suction, and collection to be achieved, making it faster to complete the preoperative instrument inventory and preoperative preparation. When in use, select according to the needs, and the operation is convenient and fast. Description of the Drawings

[0027] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of this application or its application or use. Embodiment

[0028] As Figure 1 shown, a multi-functional catheter provided by this application includes a main catheter 1, a Luer connector 2, a horn interface 301, a sputum suction interface 302, an oxygen supply tube 401, and a sputum suction head 402. Multiple main catheters are configured in the catheter assembly. One end of the main catheter 1 is used as a mechanical end and is connected to a mechanical device using a suitable connector, and the other end is used as a patient end and is inserted into the patient's airway using a suitable connector. Embodiment

[0029] As Figure 2 shown, based on the technical solution provided in Embodiment 1, the difference from Embodiment 1 is that the mechanical end is connected to the horn interface 301 through the Luer connector 2. When the patient end is connected to the oxygen supply tube 401 through the Luer connector and used, the horn interface 301 can be connected to an oxygen supply device, and the oxygen supply tube 401 is inserted into the patient's airway to realize the function of supplying oxygen to the patient.

[0030] As Figure 3 shown, the mechanical end is connected to the horn interface 301 through the Luer connector. One end of the oxygen supply tube 401 is connected to the patient end through the Luer connector, and the other end of the oxygen supply tube 401 is connected to the spraying head 403. The catheter connecting the spraying head 403 and the oxygen supply tube 401 is curved to better align with the surface of the patient's airway.

[0031] The horn interface 301 is connected to a drug delivery device, and the oxygen supply tube 401 with the spraying head 403 is inserted into the patient's airway. Drugs are sprayed onto the airway epidermis through the spraying head 403 for topical anesthesia of the airway.

[0032] As Figure 4As shown, the mechanical end is connected to the sputum aspiration interface 302 through a luer connector, and the patient end is connected to the sputum aspiration head 402 through a luer connector 2. The sputum aspiration head 402 is a flexible tube with fine holes on its side wall and is used to be inserted into the patient's airway. A through hole and a plug body are also provided on the side wall of the sputum aspiration interface 302. The through hole is opened and closed by the plug body or fingers to achieve pressure control during the sputum aspiration process.

[0033] The sputum aspiration interface 302 is connected to a negative pressure device, and the sputum aspiration head 402 is inserted into the patient's airway to achieve sputum aspiration.

[0034] The mechanical end of the main conduit 1 is connected to an end-tidal carbon dioxide monitor through a luer connector 2, and the patient end of the main conduit 1 is connected to a three-way connection on the patient's breathing pipeline through a luer connector 2 for collecting end-tidal carbon dioxide in the patient's body.

[0035] During use, different connectors are connected to both ends of the main conduit according to different usage requirements to achieve functions. During preoperative preparation, it is not necessary to prepare all the conduits. The conduit connectors and conduits that may be used before establishing an artificial airway are gathered together to speed up the preoperative instrument inventory, thereby accelerating preoperative preparation. The conduits and connectors are gathered together. The conduit assembly can be configured with multiple main conduits. During use, it can meet the usage tools for multiple operations and better handle the different tool usages for multiple operations.

[0036] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present application.
