Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cannulation guide. Background Technology

[0002] Endotracheal intubation is an emergency procedure in which a specially designed endotracheal tube is inserted into the trachea through the mouth or nose and through the glottis. Its purpose is to provide ventilation and oxygen supply, airway suction to prevent aspiration, maintain airway patency, and provide effective conditions for assisted breathing.

[0003] Current endotracheal intubation procedures require the use of a guidewire. The guidewire must first be inserted into the target site, and then the tubular instrument is advanced along the guidewire to the predetermined position. Existing guidewires are thin, long metal wires with a relatively simple structure, providing only a guiding function and lacking other features, thus limiting their practicality. Furthermore, they lack sufficient shaping ability and stability, making them prone to deviating from the target position during intubation. They also have shortcomings in judging intubation depth and position, increasing the difficulty and risk of the procedure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] The cannulation guide includes: a guide tube, on which a multifunctional shaping guide structure is mounted;

[0006] The multifunctional shaping and guiding structure includes: a guiding cavity, an inserting groove, a shaping memory metal strip, a multifunctional combination sleeve, and a cannula insertion head;

[0007] The guide cavity is opened through the inside of the guide tube, the insertion groove is opened on the outer wall of the guide tube, the shaped memory metal strip is wrapped and installed in the insertion groove, the multi-functional combination sleeve is installed at the top of the guide tube, and the insertion head is installed as an integral part at the lower end of the guide tube.

[0008] Preferably, the outer wall of the guide tube is provided with graduation lines.

[0009] Preferably, the multi-functional combination sleeve is equipped with a locking ring.

[0010] Preferably, a locking groove is provided at the top of the inner wall of the guide cavity.

[0011] Preferably, the end of the cannula insertion head is provided with an arc-shaped chamfer.

[0012] Preferably, the cannula insertion head has a flexible, curved structure.

[0013] Beneficial effects

[0014] This utility model provides a cannulation guide, which has the following beneficial effects:

[0015] This solution utilizes a multifunctional shaping guide structure, departing from the traditional single-wire structure. It employs a shape-adjustable tubular structure that is both flexible and harmless to the body while providing shaping guidance, ensuring stability during treatment. The internal cavity allows for multiple treatment functions, and external graduations allow for observation of insertion depth. This solution addresses the problems of existing endotracheal intubation guide wires, which are thin, long wires with simple structures, offering only a single guiding function and lacking other features, thus limiting their practicality. Furthermore, they lack sufficient shaping ability and stability, leading to easy deviation from the target position during intubation and inadequate judgment of intubation depth and position, increasing the difficulty and risk of the procedure.

[0021] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a cannulation guide. Considering that the existing metal wire guide wires provide relatively simple functions and have poor shaping effects, which affect the cannulation treatment effect, this solution sets up the following technical means based on the above.

[0023] Specifically, this device includes at least a guide tube 1, a guide cavity 2, an insert groove 3, a shape memory metal strip 4, a multi-functional combination sleeve 5, and an insertion head 6;

[0024] The guide tube 1 serves as the device base and connects to other device components. During use, it is inserted into the patient's trachea with the curved intubation head 6 at the front end. The guide tube 1 is shaped and adjusted according to the patient's internal condition through the shaping memory metal strip 4 installed in the mounting groove 3, making it easier for the device to be inserted into the trachea. This ensures that the device is not harmed to the patient's body while enabling rapid operation. The intubation head 6 at the front end of the guide tube 1 is an integral flexible tube to prevent injury to the patient. When the guide tube 1 is inserted, the insertion length is observed according to the scale line 7 on the outer wall to determine the insertion position. After insertion, the shaping and guiding function of the guide tube 1 can guide the medical device (such as endotracheal tube) into the patient's trachea for operation.

[0025] When oxygen supply is required, the multifunctional combination sleeve 5 is fixed into the clamping groove 9 by the clamping ring 8 installed on it. The multifunctional combination sleeve 5 is connected to the oxygen supply equipment, and oxygen supply is achieved through the guide cavity 2. Alternatively, the multifunctional combination sleeve 5 can be removed, and optical fibers can be inserted through the guide cavity 2 for temporary lighting. Temporary negative pressure suction can also be achieved through the guide cavity 2, thereby realizing multifunctional guided therapy.

[0026] More specifically, the guide cavity 2 is opened through the inside of the guide tube 1, the mounting groove 3 is opened on the outer wall of the guide tube 1, the shaped memory metal strip 4 is wrapped and installed in the mounting groove 3, the multi-functional combination sleeve 5 is assembled and installed at the top position of the guide tube 1, and the insertion head 6 is integrated and installed at the lower end of the guide tube 1.

[0027] In the specific implementation process, furthermore, a scale line 7 is provided on the outer wall of the guide tube 1, so that the insertion depth can be observed in real time when the guide tube 1 is inserted, thereby controlling the insertion position.

[0028] In the specific implementation process, the multi-functional combination sleeve 5 is further provided with a clamping ring 8, and a clamping groove 9 is opened at the top of the inner wall of the guide cavity 2, so as to increase the connection stability between the multi-functional combination sleeve 5 and the guide tube 1 through the combination connection.

[0029] In the specific implementation process, the end of the cannula insertion head 6 is further provided with an arc-shaped chamfer. The cannula insertion head 6 is a flexible bending structure. The flexible bending structure can ensure different guiding insertion angles while preventing harm to the patient. At the same time, the arc-shaped chamfer at the end further protects the patient and prevents medical accidents.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
