Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a multifunctional visual suction catheter. Background Art
[0002] Clinically, many comatose and patients with weak expectoration ability have difficulty in discharging sputum due to the decline of their cough and swallowing functions. The increase in sputum production, sputum discharge disorder and sputum retention are likely to cause many harms, such as: dyspnea, aggravated infection, prolonged rehabilitation time, hypoxia-induced cardiovascular and cerebrovascular related diseases, etc., and can cause asphyxia and death in severe cases. It is common in patients with chronic obstructive pulmonary disease, after major surgery anesthesia, cerebrovascular accident, chronic neurological diseases affecting respiratory muscles, severe pulmonary infection, and long-term tracheal intubation population, etc., and the incidence rate remains high.
[0003] The current solution mainly uses a suction catheter for negative pressure suction. However, the existing suction catheters have the following disadvantages: they have no visual function or the visual structure is poor, it is very difficult to enter the specific bronchi on the left and right sides specifically, and medical staff need to rely on experience to master the sputum aspiration situation in the patient's body, which not only easily damages the airway, is inconvenient to operate, but also increases the operation difficulty of medical staff.
[0004] Therefore, designing a brand-new multifunctional visual suction catheter has become one of the important research directions in this field. Content of the Utility Model
[0005] The purpose of the utility model is to provide a multifunctional visual suction catheter.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is specifically as follows:
[0007] A multifunctional visual suction catheter includes a catheter. The catheter has a double-cavity structure, including a visual channel and a suction channel that are parallel to each other; the upper part of the catheter is connected to a connector seat, and a fixed connector is provided on the connector seat, and the fixed connector is communicated with the visual channel; a Luer connector and a suction tube are installed on the side of the connector seat, and both the Luer connector and the suction tube are communicated with the suction channel; an aspiration connector is provided on the upper part of the suction tube, and an aspiration outlet is provided at the top of the aspiration connector.
[0008] Further, a visual window is provided at the lower part of the visual channel.

[0012] Further, the hardness of the material of the lower part of the catheter is less than that of the middle and upper parts of the catheter, and the lower part of the catheter is the part with a length of 3-8 cm from the end of the catheter.
[0013] Further, the fixed joint includes two or more boss joints for fixing the conical plug of the endoscope insertion part.
[0014] Further, the material of the visual window is a highly transparent flexible material.
[0015] Compared with the prior art, the outstanding effects of the present utility model are as follows:
[0016] (1) The catheter of the multifunctional visual suction catheter is of a double-chamber structure. The endoscope can be inserted through the fixed joint and the visual channel to the bottom of the suction catheter, and the suction port can be guided to suck under visual observation. Suction under visual observation ensures cleaner and more thorough cleaning.
[0017] (2) The catheter of the multifunctional visual suction catheter of the present utility model is made of two kinds of soft and hard tube materials, upper and lower.

Detailed Embodiments
[0022] Such as Figure 1As shown in the figure, a multi-functional visible sputum aspirator tube includes a catheter 1. The catheter 1 has a double-lumen structure and includes a visible channel 13 and a suction channel 14 that are parallel to each other. The upper part of the catheter 1 is connected to a connector seat 2. A fixed connector 3 is provided on the connector seat 2, and the fixed connector 3 is communicated with the visible channel 13. A Luer connector 4 and a suction tube 6 are installed on the side of the connector seat 2. Both the Luer connector 4 and the suction tube 6 are communicated with the suction channel 14. An aspiration connector 7 is provided at the upper part of the suction tube 6, and an aspiration outlet 12 is provided at the top of the aspiration connector 7.
[0023] A visible window 10 is provided at the lower part of the visible channel 13. An aspiration inlet 11 is provided at the lower part of the suction channel 14.
[0024] The fixed connector 3 includes two or more boss connectors, which are used to firmly hold the conical plug of the endoscope insertion part, making it convenient and fast.
[0025] A Luer connector cap 5 is provided on the outer wall of the Luer connector 4. An aspiration adjustment cap 8 and an aspiration cap 9 are provided on the outer wall of the aspiration connector 7.
[0026] The hardness of the material of the lower part of the catheter 1 is less than that of the middle and upper parts of the catheter 1. The lower part of the catheter 1 is the part with a length of 3 - 8 cm from the end of the catheter 1.
[0027] During use, the endoscope is inserted through the fixed connector 3 and the visible channel 13 to the visible window 10 at the bottom of the sputum aspirator tube. The visible window 10 is made of a highly transparent flexible material, which meets the light transmission of the lens and can also meet the perfect fit between the endoscope lens and the window to achieve a better visible image effect.
[0028] The hardness of the material of the middle and upper parts of the catheter 1 is moderate, which is convenient for the sputum aspirator tube to have sufficient supporting force during the catheter insertion process and is convenient for catheter insertion. Since some patients need to insert the sputum aspirator tube into the bronchus for sputum aspiration, and since there are certain angular inclinations between the inlets of the left and right bronchi and the main trachea, it is very difficult to insert the sputum aspirator tube into the bronchus in the normal direction under normal non-visible conditions. Therefore, the lower part of the catheter of the sputum aspirator tube (the part with a length of 3 - 8 cm from the end of the catheter 1) is made of a flexible material with a lower hardness, which matches the curved part of the front-end snake bone of the endoscope, so as to facilitate driving the flexible outer wall of the sputum aspirator tube covered by the front-end snake bone of the endoscope. In this way, the sputum aspirator tube can be easily inserted into the bronchial inlet that needs to be inserted under the observation of the visible endoscope.
[0029] The suction channel 14 of the catheter 1 is connected to the Luer connector 4 and the suction tube 6 through the connector seat 2. During use, when the visible sputum aspirator tube is inserted into the correct position, the Luer connector cap 5 is covered, and the aspiration outlet 12 on the aspiration connector 7 is connected to a negative pressure aspirator to perform negative pressure aspiration. The aspiration speed can be adjusted by pressing the size of the aspiration adjustment cap 8 with fingers, which can achieve the effect of fast and convenient sputum aspiration.
[0030] When the visual window 10 is blocked by secretions or sputum, it can be rinsed by connecting a syringe through the Luer connector 4, which can clean the window to avoid blocking the visual field. When the secretions are relatively viscous and block the suction channel 14, the suction outlet 12 can be covered by the suction cap 9, and it can be cleaned by inflating or flushing physiological saline in a sealed state through the Luer connector 4 to achieve an ideal suction effect.
[0031] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. It should not be understood as a limitation of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
