DETAILED DESCRIPTION

[0021] The technical solution provided by the present invention is further described below in conjunction with the accompanying drawings and according to specific implementation methods.

[0022] like Figure 1 to Figure 7 As shown, it includes a supporting mechanism 2, a sputum suction mechanism 1 is fixedly installed at the front end of the supporting mechanism 2, the supporting mechanism 2 includes a pair of neck clamping brackets 203, the neck clamping brackets 203 are used to clamp the patient's throat, so that the patient's neck remains in a straight state, help the patient open the throat, and facilitate the discharge of sputum, the neck clamping brackets 203 are hinged to each other through connecting pins 212, and a plurality of baffle support frames 204 are fixedly installed on the neck clamping bracket 203, a first elastic baffle 201 is fixedly installed on the outer side of the baffle support frame 204, an air suction port 202 is fixedly installed on the outer side of the first elastic baffle 201, and the air suction port 202 is connected to the sputum suction mechanism 1 through a pipeline, the baffle support frames 204 are evenly arranged on the neck clamping bracket 203, a reset elastic plate 205 is fixedly installed between the front ends of two opposite baffle support frames 204, and a reset tension spring 213 is fixedly installed between the rear ends of two opposite baffle support frames 204, which is used to support the baffle support frame 204 and keep enough space inside the neck clamping bracket 203.

[0023] like Figure 1 to Figure 7As shown, the neck clamping bracket 203 has a second transmission short rod 210 at both ends of the upper and lower ball joints, and the supporting mechanism 2 includes a first transmission short rod 208. The first transmission short rod 208 has connecting end rods 209 installed at both ends for transverse rotation. The connecting end rod 209 is connected to the top of the second transmission short rod 210 by a ball joint. The top of the connecting pin 212 is hinged with a special-shaped transmission rod 207, and the special-shaped transmission rod 207 is a J-shaped rod. The front end of the first transmission short rod 208 is fixedly installed with a connecting key, and the middle section of the special-shaped transmission rod 207 is hinged with the connecting piece on the first transmission short rod 208. The top of the special-shaped transmission rod 207 is fixedly installed with an arc support plate 206. A second elastic baffle 214 is fixedly installed on the outside of the arc support plate 206, and the second elastic baffle 214 contacts and cooperates with the first elastic baffle 201. Arc support rods 211 are longitudinally rotatably installed at both ends of the arc support plate 206. A slide groove is provided on the top of the neck clamping bracket 203, and a ball bar is fixedly installed on the bottom of the arc support rod 211. The ball bar at the bottom of the arc support rod 211 is slidably installed in the slide groove on the top of the neck clamping bracket 203. The arc support plate 206 is used to contact the patient's lower jaw and chest position, and is used to control the clamping tightness of the neck clamping bracket 203 to ensure the stability of the equipment. When the patient uses it, the supporting mechanism 2 is placed on the pharynx. The patient then places the neck clamping bracket 203 on the throat and fits the two arc-shaped support plates 206 to the chin and chest respectively. The patient then lowers his head to push the arc-shaped support plate 206 down, and drives the special-shaped transmission rod 207 to rotate on the connecting pin 212 through the arc-shaped support plate 206. The special-shaped transmission rod 207 pulls the first transmission short rod 208, and the first transmission short rod 208 drives the second transmission short rod 210 to pull the neck clamping bracket 203 to rotate, clamping both sides of the throat, so that the device can be fixed on the patient's throat, allowing the patient to free his hands to perform other steps to clean the sputum by himself.

[0024] like Figure 1 to Figure 7 As shown, the sputum suction mechanism 1 includes a first air suction pipe 105, the rear end of the first air suction pipe 105 is fixedly connected to the air suction port 202, and a suction cylinder 103 is fixedly installed at the front end of the first air suction pipe 105. The suction cylinder 103 is used to extract the air in the neck clamping bracket 203, and the negative pressure in the neck clamping bracket 203 increases the opening amplitude of the patient's throat, which is helpful for the discharge of sputum and allows the patient to breathe more smoothly when clearing the sputum. A second air suction pipe 106 is fixedly installed at the front end of the suction cylinder 103, and a sputum suction outer pipe 101 is fixedly installed at the front end of the second air suction pipe 106. The sputum suction outer pipe 101 is semi-cylindrical, and an axial semicircular groove is provided on the plane of the sputum suction outer pipe 101. The sputum suction outer pipe 101 is used to extend into the throat from the side of the patient's oral cavity for suctioning sputum, and the sputum suction outer pipe 101 has a semicircular groove portion facing the patient's tongue, which reduces the nausea caused by foreign objects extending into the oral cavity when clearing sputum.

[0025] like Figure 1 to Figure 7 As shown, a limit baffle 111 is fixedly installed at the bottom of the sputum suction outer pipe 101, and the limit baffle 111 is used to limit the insertion depth of the sputum suction outer pipe 101 to prevent the sputum suction outer pipe 101 from extending too deeply and injuring the patient's throat. A sputum suction inner pipe 102 is fixedly installed in the sputum suction outer pipe 101, and the sputum suction inner pipe 102 is a detachable and replaceable component. An adsorption brush is fixedly installed on the inner wall of the sputum suction inner pipe 102, and the adsorption brushes in the sputum suction inner pipe 102 are evenly arranged inside. The adsorption brushes in the sputum suction inner pipe 102 are used to adsorb and fix the patient's sputum to prevent the sputum from flowing into the vacuum cylinder 103 through the sputum suction inner pipe 102 and affecting the vacuum effect. At the same time, the detachable sputum suction inner pipe 102 can improve the cleaning efficiency of the equipment.

[0026] like Figure 1 to Figure 7 As shown, the first exhaust pipe 105 and the second exhaust pipe 106 are respectively connected to the exhaust cylinder 103 with an exhaust check valve 109 fixedly installed inside, the exhaust cylinder 103 has an exhaust port 107 fixedly installed at the bottom, the exhaust port 107 is used to exhaust the air extracted from the neck clamping bracket 203 and the patient's mouth, the exhaust check valve 110 is fixedly installed in the exhaust port 107, a exhaust handle 104 is longitudinally slidably installed in the exhaust cylinder 103, the exhaust handle 104 and the bottom of the exhaust cylinder 103 are fixedly installed with a compression spring, the rear end of the second exhaust pipe 106 has a dehumidification filter tube 108 fixedly installed inside, the dehumidification filter tube 108 is used to absorb moisture in the extracted air to prevent moisture from adhering to the inside of the equipment and breeding bacteria.

[0027] Working principle: When a patient needs to clean sputum by himself, he first places the supporting mechanism 2 on the throat and makes the neck clamping bracket 203 fit on both sides of the throat. Then, he lowers his head to drive the neck clamping bracket 203 to clamp the neck, so that the supporting mechanism 2 is fixed on the patient's neck, freeing the patient's hands to clean sputum.

[0028] Then, the external suction pipe 101 is inserted into the throat through the side of the oral cavity, and then the suction handle 104 is pressed to slide back and forth in the suction cylinder 103, and the sputum in the patient's throat is sucked out by negative pressure. At the same time, the negative pressure in the neck clamping bracket 203 increases the opening degree of the patient's throat, thereby improving the discharge efficiency of sputum. At the same time, due to the gap between the second elastic baffle 214 and the first elastic baffle 201 when in contact, the external air enters the neck clamping bracket 203 through the gap, balancing the negative pressure in the neck clamping bracket 203, so that the negative pressure frequency inside the neck clamping bracket 203 matches the suction frequency of the sputum suction internal pipe 102, thereby reducing the patient's discomfort.

[0029] During the suction process, the suctioned sputum is fixed by the adsorption brush in the suction inner tube 102, and the sputum is fixed to the inner wall of the suction inner tube 102 by utilizing the surface tension of the liquid, and a space for air circulation is left in the center of the suction inner tube 102, thereby preventing the accumulation of sputum from causing the suction inner tube 102 to be unable to ventilate normally and affecting the sputum removal effect.
