Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sputum suction tubes, in particular to a sputum suction tube. Background Art
[0002] The suction tube is used to extract sputum and other secretions from the patient's respiratory tract. Its main function is to help clear sputum from the respiratory tract, and it is particularly suitable for patients on mechanical ventilation, patients with neuromuscular diseases, patients in coma or impaired consciousness, and patients after surgery. The suction tube is usually composed of a pipe, a connector, and a suction head, and its structural design is simple and practical. When in use, medical staff need to insert the suction tube into the patient's oral or nasal cavity, along the endotracheal intubation or tracheotomy tube into the deep airway, and then use a manual or mechanical suction device to generate appropriate negative pressure so that the sputum in the tube is sucked into the suction device. During operation, care should be taken not to generate excessive suction to avoid damaging the patient's respiratory tissue; for example, a sputum suction tube disclosed in the authorization announcement number CN219646374U includes a sputum cup and a sputum suction tube body, a sputum cover is fixedly connected to the top of the sputum cup, a sputum suction tube body and a negative pressure tube are respectively sealed and connected to the top of the sputum cover, a sputum suction tube contact is connected to the side of the sputum suction tube body away from the sputum cover, a side suction hole is provided on the outer surface of the sputum suction tube body, a suction port is provided on the surface of the sputum suction tube contact, and the sputum suction tube contact is tilted downward along the sputum suction tube body at an inclination angle of 50°-6 0°, a negative pressure joint is provided on the side of the negative pressure tube away from the sputum cover, and two side suction holes are provided on the outer surface of the suction tube body away from the sputum cover, which are respectively located on both sides of the suction tube body to speed up the suction efficiency. However, the suction tube body of this technical solution still adopts an "O"-shaped nozzle and tube design. The smaller the nozzle and the smaller the suction force, the more restricted the flow rate of the extracted sputum is. Especially for users with thick or large amounts of sputum in their bodies, insufficient flow will make it difficult to effectively clear the secretions in the respiratory tract, resulting in incomplete clearing or a longer extraction process. Utility Model Content
[0003] The utility model aims to provide a sputum suction tube, at the end of which a double-channel flat-mouth liquid suction structure is designed so that the sputum suction tube forms two liquid suction points at its end to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-5 The utility model provides an embodiment: a sputum suction tube, comprising a connector 1 and external threaded joints 2 and a sputum suction hose 3 respectively installed at both ends of the connector 1, the external threaded joint 2 is connected to a sputum suction device, a sputum suction hose 3 is installed at one end away from the connector 1 with a rotary joint 4, and a conducting tube 5 is installed at the rotating end of the rotary joint 4, and a double-channel flat-mouth liquid suction structure is installed at one end of the conducting tube 5 away from the rotary joint 4;
[0019] A bag receiving spout 101 is installed on one side of the top of the connector 1. The bag receiving spout 101 is connected to the sputum bag through a hose, which provides a special collection container for conveniently collecting and storing sputum, thereby preventing the sputum from being directly exposed to the outside world.
[0020] The surface of the sputum suction hose 3 is provided with a corrugated expansion joint 301, which enables the sputum suction hose 3 to be more capable of bending and twisting during use, thereby enhancing its flexibility, which is very important for situations where sputum suction is required in complex locations, such as when a comatose patient or a ventilator is connected, so that the position and angle of the tube can be adjusted more easily, ensuring effective sputum extraction without affecting the patient's comfort;
[0021] The double-channel flat-mouth liquid suction structure includes a Y-shaped connecting tube 6 threadedly installed at one end of the guide tube 5 and a straight-mouthed flat tube 7 fixed on the outer peripheral surface of the Y-shaped connecting tube 6. Two symmetrical sputum suction nozzles 8 are installed inside the straight-mouthed flat tube 7. The sputum suction nozzle 8 is concentric and colinear with the tube mouth of the Y-shaped connecting tube 6, and one end of the sputum suction nozzle 8 extends to the inside of the Y-shaped connecting tube 6. A liquid storage cavity 701 is arranged inside the straight-mouthed flat tube 7. A plurality of connecting holes 801 arranged in an array and interconnected with the liquid storage cavity 701 are arranged on the outer wall of the sputum suction nozzle 8. The staff pushes the Y-shaped connecting tube 6, the straight-mouthed flat tube 7, and the sputum suction nozzle 8 from the patient's mouth into his respiratory tract. Compared with the traditional circular tube mouth, the flat mouth of the straight-mouthed flat tube 7 can more effectively adapt to the patient's oral shape, reduce the discomfort and stimulation to the oral soft tissue, improve the comfort during use, and better fit the sealing around the lips, ensuring that the negative pressure generated during the sputum suction operation can fully extract sputum;
[0022] Both ends of the surface of the sputum suction nozzle 8 are provided with an enlarged diameter portion 802, and the outer diameter of the tube opening of the sputum suction nozzle 8 is equal to the inner diameter of the tube opening of the Y-shaped connecting tube 6. When the sputum suction hose 3 generates negative pressure, the sputum suction nozzle 8 extracts sputum and sends the sputum into the liquid storage cavity 701 of the straight flat tube 7. The connecting hole 801 makes the liquid storage cavity 701 and the interior of the sputum suction nozzle 8 in a conducting state, and finally the extracted sputum is sent to the sputum suction hose 3 through the Y-shaped connecting tube 6 to complete the sputum extraction operation;
[0023] The suction hose 3 and the suction nozzle 8 are both made of silicone material. The silicone material is very soft and can better fit the patient's mouth and lips, reducing the discomfort and irritation that may be caused by hard materials.
[0024] When the embodiment of the present application is in use, the staff first connects the external threaded connector 2 to a sputum suction device, such as a manual suction device or a mechanical suction device, so as to generate negative pressure inside the external threaded connector 2, the sputum suction hose 3 and other structures to suction sputum, and the bag receiving nozzle 101 is connected to the sputum bag through a hose. Then the staff ensures that the patient's head is in an appropriate position to avoid accidental aspiration, inserts the double-channel flat-mouth suction structure at the end of the sputum suction hose 3 into the patient's mouth, enters the deep part of the airway along the respiratory tract, and gently pushes the pipe until it reaches the target position, and then generates appropriate negative pressure through a manual or mechanical suction device to cause the sputum in the sputum suction hose 3 and the double-channel flat-mouth suction structure to be sucked out. When suctioning, be careful not to generate too much suction to avoid damaging the patient's respiratory tissue. After the suction is completed, carefully remove the tube from the patient's airway. During this process, the double-channel flat-mouth suction structure forms two suction points at the end of the suction hose 3, which can effectively improve the extraction efficiency. By increasing the number of suction points, the suction tube can extract more sputum more quickly at the same time, thereby improving the extraction efficiency and shortening the operation time. With two suction points working at the same time, it is easier to ensure the contact between the suction point and the sputum. For first aid and emergency situations that require fast and accurate operations, the operating efficiency of medical staff can be improved.
[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
