[0039] A rotating handle 55 is rotatably connected inside the vertical part of the three-way pipe 5, and a ball valve 56 is fixed at the bottom of the vertical part of the rotating handle 55. The ball valve 56 is rotatably connected inside the horizontal part of the three-way pipe 5. Upper fixing frames 501 are fixed on both sides of the top of the horizontal part of the three-way pipe 5, and an upper sealing groove 502 is opened inside the upper fixing frame 501. A lower fixing frame 503 is fixed at the bottom of the horizontal part of the three-way pipe 5, and a lower sealing groove 504 is opened inside the lower fixing frame 503. A sputum suction tube 6 is slidably sleeved inside a conical groove 51 without a guide hose 4. The sputum suction tube 6 is inclined to the inner wall of the clamping part of the conical groove 51, and the inclined part is in contact with the inner wall of the conical groove 51.

[0040] A triangular plate 57 is fixed on the outside of the vertical part of the rotating handle 55, and a liquid injection pipeline 7 is opened on both sides of the vertical part of the three-way pipe 5, and the top of the liquid injection pipeline 7 is filled with a rubber plug. The liquid injection pipeline 7 is connected to the liquid storage tank 53, and a push rod 71 is slidably connected inside the sliding groove 54. A linkage plate 72 is fixed on one end of the push rod 71 close to the liquid injection pipeline 7. The linkage plate 72 is located inside the liquid storage tank 53, and the linkage plate 72 is L-shaped.

[0041] A sealing block 73 is clamped inside the sealing slot 52, and the sealing block 73 abuts against the linkage plate 72. A plurality of notches are provided on the surface of the horizontal portion of the rotating handle 55. A locking plate 8 is bonded to the outside of the vertical portion of the tee pipe 5 near the suction tube 6, and the top end of the locking plate 8 is clamped inside one of the notches.

[0042] During the specific operation, firstly, the two ends of the filter tube 23 are respectively sleeved on the outside of the air inlet pipe 21 and the air outlet of the sputum suction device main unit 1, so that the liquid storage tank 11 and the sputum suction device main unit 1 are connected to each other, and then one end of the guide hose 4 is sleeved on the outside of the air extraction pipe 22, and this end is simultaneously clamped on the inside of the outer support frame 3, and under the elastic force of the spring 31, the spring 31 drives the movable splint 32 to squeeze on the outside of the guide hose 4, thereby strengthening the sealing and stability of the sleeve connection between the guide hose 4 and the air extraction pipe 22, and improving the efficiency of the negative pressure sputum suction of the sputum suction device main unit 1;

[0043] Then, the tee pipe 5 is sleeved on the outside of the end of the guide hose 4 away from the exhaust pipe 22, so that the end of the guide hose 4 away from the exhaust pipe 22 is clamped into the inside of the tapered groove 51. Since the inner walls of the two tapered grooves 51 are tapered, and the inner walls of the tapered grooves 51 gradually reduce the inner diameter of the tapered grooves 51 from the two ends of the tee pipe 5 toward the center of the tee pipe 5, the guide hose 4 gradually fits with the inner wall of the tapered groove 51 after being clamped into the inside of the tapered groove 51, thereby ensuring the sealing and stability of the connection between the guide hose 4 and the tee pipe 5.

[0044] Subsequently, the sputum suction tube 6 is clamped into the inside of a conical groove 51 away from the guide hose 4. Since the end of the sputum suction tube 6 close to the conical groove 51 is inclined, when the sputum suction tube 6 is clamped into the inside of the conical groove 51, as the sputum suction tube 6 gradually goes deeper into the conical groove 51, until the sputum suction tube 6 is completely in contact with the inner wall of the conical groove 51, the sealing and stability of the connection between the sputum suction tube 6 and the conical groove 51 are ensured, and the assembly of the present invention is completed;

[0045] In actual use, it is necessary to moisten the inside of the guide hose 4 and the sputum suction tube 6 in advance, and test the negative pressure strength and sealing performance. First, adjust the sputum suction device main unit 1 to a suitable negative pressure through the air pressure adjustment knob on the surface of the sputum suction device main unit 1, and then start the sputum suction device main unit 1 through the switch provided on the surface of the sputum suction device main unit 1, and then immerse the end of the sputum suction tube 6 connected to the three-way pipe 5 in physiological saline, and then turn the locking plate 8 to release the locking plate 8 and the horizontal notch of the rotating handle 55. The locking plate 8 is torn off the surface of the three-way pipe 5, thereby unlocking the locking plate 8 from the rotating handle 55.

[0046] After the lock of the rotating handle 55 is released, the medical staff moves the rotating handle 55 by friction, so that the rotating handle 55 drives the ball valve 56 to rotate. After the ball valve 56 rotates 90 degrees, the ball valve 56 is completely connected with the horizontal part of the three-way pipe 5, that is, the guide hose 4, the three-way pipe 5 and the sputum suction tube 6 are connected, so that the sputum suction device host 1 performs negative pressure adsorption on the guide hose 4, the three-way pipe 5 and the sputum suction tube 6 through the filter tube 23, the air inlet pipe 21, the liquid storage tank 11 and the air suction pipe 22, so that the inside of the guide hose 4, the three-way pipe 5 and the sputum suction tube 6 are all moistened, ensuring the smoothness of sputum suction;

[0047] Furthermore, during the rotation of the ball valve 56, the ball valve 56 drives the triangular plate 57 to rotate synchronously. During the rotation, the triangular plate 57 gradually approaches and contacts the two push rods 71, so that the triangular plate 57 pushes the two push rods 71 ​​to slide inside the sliding groove 54 while following the rotation of the ball valve 56, and then the linkage push rod 71 pushes the linkage plate 72 to slide inside the liquid storage tank 53, and then the linkage plate 72 abuts against the sealing block 73, and the two sealing blocks 73 are respectively pushed out toward the direction of the guide hose 4 and the sputum suction tube 6, thereby making the sealing groove 52 lose the sealing of the sealing block 73, and then the liquid storage tank 53, the sealing groove 52 and the tapered groove 51 are interconnected;

[0048] As a result, the instant glue stored in the liquid storage tank 53 flows through the sealing card groove 52 and enters the tapered groove 51, so that the guide hose 4 and the sputum suction tube 6 are respectively bonded to the inner walls of the two tapered grooves 51, thereby further improving the sealing and stability of the connection between the guide hose 4 and the sputum suction tube 6 and the three-way tube 5, and reducing the loosening and air leakage at the connection between the guide hose 4, the three-way tube 5 and the sputum suction tube 6 when the medical staff pulls the sputum suction tube 6 or the guide hose 4, thereby improving the stability of the negative pressure and the efficiency of sputum suction during sputum suction of the present invention, and after the sealing test is completed, the sputum suction operation can be performed on the patient;

[0049] Furthermore, compared with the push-type valve in the traditional suction device, the present invention adopts a ball valve 56, which avoids the medical staff from applying force to press the valve for a long time to maintain the unobstructed state of the guide hose 4 and the suction tube 6, reduces the hand fatigue of the medical staff, and enables the medical staff to be more precise when operating the suction tube 6 to suction sputum in the patient's mouth, and reduces the discomfort to the patient's mouth caused by the shaking of the hands due to fatigue. After the ball valve 56 is opened, the medical staff can hold the guide hose 4 or the suction tube 6 in a comfortable posture, and when the suction force of the suction needs to be adjusted, the handle 55 can be turned to adjust the flow rate connecting the ball valve 56 with the guide hose 4 and the suction tube 6, and then the suction force of the suction can be adjusted more finely, thereby enhancing the efficiency of the suction.

[0050] It should be noted that the three-way pipe 5 is composed of two half bodies spliced ​​together, and the splicing part is the upper fixing frame 501 and the lower fixing frame 503. At the same time, the sealing strips are clamped inside the upper sealing groove 502 and the lower sealing groove 504, and the two half bodies of the three-way pipe 5 are spliced ​​into a whole by hot-melt connection. After the three-way pipe 5 is spliced ​​together, the instant glue is injected into the inside of the liquid storage tank 53 through the liquid injection pipeline 7, and the liquid injection pipeline 7 is sealed with a rubber plug, so that the instant glue is stored in the liquid storage tank 53, so as to be used after the present invention is unpacked;

[0051] At the same time, the thickness of the horizontal part of the sealing block 73 is lower than the opening thickness of the sealing slot 52, that is, after the linkage plate 72 pushes out the sealing block 73, the liquid storage tank 53 remains connected with the sealing slot 52 and the conical slot 51, ensuring that the instant glue can completely enter the interior of the conical slot 51 to seal and bond the guide hose 4 and the suction tube 6.

[0052] Embodiment 2:

[0053] A support plate 81 is fixed to the bottom of the locking plate 8, a slide bar 82 is slidably connected to the inside of one side of the support plate 81, a bottom plate 83 is fixed to the bottom of the slide bar 82, a lead screw 84 is rotatably connected to the top of the bottom plate 83 away from the slide bar 82, the lead screw 84 is threadedly connected to the support plate 81, a first extension plate 811 is fixed to the outside of one side of the support plate 81, and a second extension plate 831 is fixed to the outside of one side of the bottom plate 83;

[0054] A support frame 85 is fixed to the outside of the first extension plate 811 and the second extension plate 831 away from the locking plate 8, and the two support frames 85 are symmetrically arranged with the suction tube 6 as the center. The surface of the support frame 85 is provided with a bite groove 86, and the bottom of both sides of the bite groove 86 is provided with an embedded groove 87, and the inside of the embedded groove 87 is bonded with a sterilized cotton 88;

[0055] Specifically, on the basis of the first embodiment, when the locking plate 8 is torn off and the fixation with the three-way pipe 5 is released, the support plate 81 and the slide bar 82 are in an active state. Before the sputum suction operation is performed on the patient, the locking plate 8 is first moved to the patient's oral cavity, so that the locking plate 8 drives the support plate 81 and the slide bar 82 to move synchronously, so that the slide bar 82 drives the bottom plate 83 and the lead screw 84 to move synchronously, so that the first extension plate 811 and the second extension plate 831 drive the two mouth-supporting frames 85 to move synchronously to the patient's oral cavity;

[0056] Then, according to the size of the patient's oral opening, the lead screw 84 is rotated, so that the lead screw 84 links the support plate 81 and the first extension plate 811 to be raised and lowered on the surface of the lead screw 84 and the slide bar 82, and then the support plate 81 drives the first extension plate 811 and the mouth-opening frame 85 to be raised and lowered, and then the distance between the two mouth-opening frames 85 is adjusted. When the distance between the two mouth-opening frames 85 matches the size of the patient's mouth opening, the patient's upper and lower teeth are respectively engaged in the two bite grooves 86, thereby avoiding the patient from accidentally biting the sputum suction tube 6 during the subsequent sputum suction process, thereby improving the convenience and stability of sputum suction by the sputum suction tube 6;

[0057] Furthermore, after the patient bites the two mouth support frames 85, when the patient's mouth produces saliva, the sterilized cotton 88 is pressed against both sides of the biting teeth to absorb the patient's flowing saliva, thereby avoiding the discomfort caused by the overflowing saliva to the patient and reducing the labor of cleaning for the patient at a later stage.

[0058] Embodiment three:

[0059] The two opening support frames 85 are fixedly connected by the limiting strip 9. There are two limiting strips 9, which are symmetrically arranged on both sides of the opening support frame 85 with the opening support frame 85 as the center. The outside of the limiting strip 9 is slidably connected with a side support frame 91. The side of the side support frame 91 close to the limiting strip 9 is provided with a side card slot 92. The side of the side support frame 91 away from the limiting strip 9 is provided with a storage groove 93. A sponge block 94 is bonded inside the storage groove 93. A sponge sheet 95 is fixed on the surface of the sponge block 94. A sponge strip 96 is fixed on the outside of the sponge sheet 95 close to the side card slot 92.

[0060] During the specific operation, based on the second embodiment, when the mouth-supporting frame 85 moves to the patient's oral cavity, the mouth-supporting frame 85 drives the two limit bars 9 to move synchronously, and the limit bars 9 drive the side support frames 91 to move to the corners of the patient's mouth. When the patient bites the mouth-supporting frame 85, the corners of the patient's mouth are contained outside the two side support frames 91 and are stuck inside the two side slots 92, so that the patient's lips are supported from four directions at the same time. At the same time, the two sponge bars 96 are also contained in the patient's oral cavity, thereby preventing the patient from applying force to bite the mouth-supporting frame 85 and the side support frames 91 by himself, and the mouth of the patient is supported by the mouth-supporting frame 85 and the side support frames 91.

[0061] Furthermore, in order to ensure the efficiency of sputum suction during the actual sputum suction process, the patient needs to lie on his side, that is, the patient's face needs to be turned toward the bed surface. After turning over, the patient's face is in a horizontal state with the bed surface. After the patient turns over, the side support frame 91 is driven to turn over synchronously, so that one of the side support frames 91 is located below the corner of the patient's mouth.

[0062] During the suction process, the patient's mouth is in an open state for a long time, so saliva will accumulate in the mouth. Under the siphon principle of the sponge strip 96, the saliva in the patient's mouth is absorbed by the sponge strip 96 and transferred to the sponge sheet 95, and then to the sponge block 94 via the sponge sheet 95, thereby avoiding discomfort to the patient caused by the saliva accumulated in the patient's mouth, and at the same time avoiding the patient swallowing saliva and affecting the suction operation of the suction tube 6, thereby improving the suction stability of the suction tube 6.

[0063] It should be noted that the side support frame 91 is slidably sleeved on the outside of the limiting strip 9, so that when the patient is actually biting the mouth support frame 85 and the side support frame 91, the medical staff can further adjust the position of the side support frame 91 according to the patient's mouth shape, so that after the patient turns sideways, the side support frame 91 is accurately located below the corner of the patient's mouth to receive and absorb the patient's saliva. At the same time, the limiting strip 9 is made of spring sheet to ensure that the mouth support frame 85 is not hindered by the limiting strip 9 during adjustment.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
