Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a sputum suction device. Background Art

[0002] During routine sputum suction, tracheotomy, pediatric intensive care and clinical nursing for the wounded and sick, many patients cannot cough up sputum by themselves, resulting in excessive sputum. If not treated in time, it will threaten the patient's life and health. Therefore, artificial assisted sputum suction is often required to keep the airway open. The sputum suction device is one of the commonly used instruments in clinical practice. It can suck out sputum in time, allowing patients to breathe smoothly and prevent airway obstruction.

[0003] However, the commonly used sputum suction devices are mostly electric, and the matching suction tubes generally use the end of the suction tube as the terminal or are equipped with a plastic terminal. When in use, the sputum suction device lacks an oral support component. When caring for the patient, the suction tube is easily compressed by the patient's bite, resulting in failure of suction. Secondly, the resistance at the throat and trachea is large, and the hose is soft and may bend and deform. If the operation is too large, the hose will bend and easily hit the throat, causing discomfort to the patient. For this reason, an improved sputum suction device has been designed. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a sputum suction device to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A sputum suction device, comprising a suction device, a sputum suction tube and a sputum suction head, wherein the suction device is connected to the sputum suction head through the sputum suction tube, the suction device generates negative pressure to suck sputum from the sputum suction head, and further comprises a support member and a rotating joint;

[0007] The support member is trumpet-shaped, movably arranged on the sputum suction tube, and can be detached from the sputum suction tube;

[0008] The rotary joint comprises a rotating body and a fixed body, wherein the rotating body is rotary sealedly connected in the fixed body, one end of the rotary joint is connected to the sputum suction tube, and the other end is connected to the suction device, thereby realizing a rotary sealed connection between the sputum suction tube and the suction device.

[0009] By adopting the above structural design, a trumpet-shaped support member is provided. When in use, the patient is asked to open his mouth, and then the support member is supported in the patient's mouth. Then the suction head and the suction tube are inserted into the patient's mouth through the support member and penetrate into the sputum stuck area, thereby preventing the patient from biting the suction tube to cause sputum suction tube blockage and sputum suction failure. The other end of the suction tube is rotatably connected to the suction device through a rotating joint. In the process of inserting the suction head into the sputum stuck area, the suction tube can be rotated to allow the suction tube to slowly rotate and penetrate into the sputum stuck area, thereby preventing the sputum tube from excessively bending and deforming to squeeze the patient's throat and cause discomfort during the penetration process.

[0010] Furthermore, the rotating body is connected to the sputum suction tube, and the fixed body is connected to the suction device.

[0011] Furthermore, the internal hollow parts of the fixed body and the rotating body are both provided with channels for medium circulation, and the two channels are interconnected. The end of the rotating body connected to the fixed body is provided with a ball head, and the end of the fixed body connected to the rotating body is provided with a spherical cavity for accommodating the ball head. The inner wall of the spherical cavity is provided with a sealing seat, and the sealing seat is provided with a spherical first sealing ring that fits with the ball head.

[0012] Furthermore, the rotary joint further comprises:

[0013] An end cover is provided on the rotating body, connected to the end of the fixed body through a fastener, and pushes and squeezes the sealing seat and the first sealing ring so that the inner wall of the first sealing ring and the outer wall of the ball head are pressed against each other;

[0014] The second sealing ring is arranged between the end cover and the ball head. The second sealing ring is in a ring shape. The rotating body is provided with a straight extension section in a direction away from the ball head. The straight extension section and the rotating body are connected in a smooth transition manner.

[0015] By adopting the above structural design, one end of the suction tube is connected to the rotating body by an interference fit connection, and the suction nozzle of the syringe is connected to the fixed body by an interference fit connection, so that the suction head, the suction tube, the rotary joint and the suction device are connected to each other, and the movement of the piston in the suction device generates negative pressure to suck in sputum. Since the rotating body is connected to the inside of the fixed body through a rotary seal, it can rotate under the action of external force, and the medium sputum can flow through the channels of the fixed body and the rotating body.

[0016] Furthermore, the rotating body and the sputum suction tube are connected by interference fit, and the fixed body and the suction device are connected by interference fit.

[0017] Furthermore, the suction device comprises a syringe, the syringe is connected to a suction nozzle, the suction nozzle is connected to a connector, a push rod is movably provided in the syringe, and a piston is connected to the push rod.

[0018] Furthermore, the suction head includes an integrally connected shell and a connector, the connector is connected to the suction tube, a main suction hole is opened at the front end center of the shell, and a plurality of auxiliary suction holes are also opened at the front end of the shell, the auxiliary suction hole is located at the rear end of the main suction hole, and the plurality of auxiliary suction holes are arranged in a circular array with the main suction hole as the center.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. A trumpet-shaped support is provided. When in use, the patient is asked to open his mouth, and then the support is supported in the patient's mouth. Then the suction head and the suction tube are inserted into the patient's mouth through the support and penetrated into the sputum stuck area to prevent the patient from biting the suction tube, causing blockage of the suction tube and suction failure. The other end of the suction tube is rotatably connected to the suction device through a rotary joint. In the process of inserting the suction head into the sputum stuck area, the suction tube can be rotated to allow the suction tube to slowly rotate and penetrate into the sputum stuck area, thereby preventing the sputum tube from excessively bending and deforming during the penetration process to squeeze the patient's throat and cause discomfort.

[0021] 2. One end of the suction tube is connected to the rotating body by an interference fit connection, and the suction nozzle of the syringe is connected to the fixed body by an interference fit connection, so that the suction head, suction tube, rotary joint and suction device are connected to each other. The movement of the piston in the suction device generates negative pressure to suck the sputum. Since the rotating body is connected to the inside of the fixed body with a rotary seal, the medium sputum can flow through the channels of the fixed body and the rotating body. At the same time, the suction tube can rotate under the action of external force, and rotate deep into the throat where the sputum is stuck. BRIEF DESCRIPTION OF THE DRAWINGS
