[0029] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See also Figures 1 to 6 This embodiment discloses a sputum suction device, which is mainly used by the elderly and children, and can perform convenient external force sputum suction operations without the aid of power supply.

[0031] The sputum suction device in this embodiment includes a barrel 1, a first pipe fitting 2, a first one-way valve joint 3, a protective member 4, a second pipe fitting 5, a second one-way valve joint 6, a third one-way valve joint 7 and a negative pressure driving member 8.

[0032] The barrel 1 is provided with a detachable cover 12, and the structure connected to the bottom of the cover 12 is a barrel 11, which is used to accommodate the sucked sputum. The barrel 11 is made of a transparent material, and scale lines are drawn on its outer wall for convenient observation of the amount of sucked sputum.

[0033] The cover body 12 is connected to a first one-way valve connector 3 and a second one-way valve connector 6, and the outer ends of the first one-way valve connector 3 and the second one-way valve connector 6 are respectively connected to a first pipe fitting 2 and a second pipe fitting 5. The first pipe fitting 2 is used to penetrate into the patient's mouth when in use, and the second pipe fitting 5 is used to connect to a negative pressure driving component 8.

[0034] The first one-way valve joint 3 and the second one-way valve joint 6 are both right-angle joints with one-way valve structures. The passing direction of the first one-way valve joint 3 is from the first pipe fitting 2 toward the barrel 1 side, and the passing direction of the second one-way valve joint 6 is from the barrel 1 toward the second pipe fitting 5 side, so that the first pipe fitting 2 can only transport sputum into the barrel 1, and the second pipe fitting 5 can only extract air from the barrel 1.

[0035] Furthermore, the first pipe 2 is a hose structure with a probe 21 connected to the outer free end, the probe 21 is provided with a suction hole, the first pipe 2 is sleeved with a protective member 4 to prevent the user's teeth from biting and pressing the first pipe 2, and the outer free end of the second pipe 5 is connected to a negative pressure driving member 8. When in use, the negative pressure driving member 8 performs negative pressure treatment on the inside of the barrel 1, so that the sputum on one side of the probe 21 can be sucked into the barrel 1.

[0036] It should be noted that, combined with Figure 6 As shown, the inner side of the cover body 12 of the barrel 1 is provided with a first inner tube 121 and a second inner tube 122 which are respectively connected to the first tube 2 and the second tube 5, and the port height of the first inner tube 121 located on the inner side of the barrel 1 is lower than the port height of the second inner tube 122 located on the inner side of the barrel 1. This structure is conducive to the misalignment and separation of the inner ports of the first inner tube 121 and the second inner tube 122, avoiding interference between the two during operation, and also helping to prevent sputum from being accidentally drawn to the negative pressure driving member 8.

[0037] Specifically, the negative pressure driving member 8 is a syringe body with a piston structure, which is convenient to operate and easy to replace.

[0038] The outer free end of the second pipe 5 is provided with a third one-way valve connector 7 of a T-shaped three-way structure, one interface of the third one-way valve connector 7 is fixedly connected to the second pipe 5, one interface is detachably plugged into the negative pressure driving member 8, and the other interface is provided with a one-way valve structure from the outer space toward the negative pressure driving member 8. This structure enables the piston-structured syringe body to reciprocate and pull the piston motion multiple times during operation, and ensures that the sputum suction process is continuous and stable.

[0039] It should be noted that the first pipe fitting 2 and the second pipe fitting 5 and the first one-way valve connector 3 and the second one-way valve connector 6 are detachable plug-in structures, which facilitates replacement of the pipe fittings and subsequent cleaning and maintenance.

[0040] Since the elderly and children may not cooperate when suctioning phlegm with the help of external force, the suction tube may be blocked due to the occlusion of the upper and lower teeth. Therefore, in this embodiment, the protective member 4 is composed of an integrally formed bite portion 41, a first flange 42 and a second flange 43. The first flange 42 and the second flange 43 are located on both sides of the axial direction of the bite portion 41, and a through hole 44 for passing the first pipe 2 is provided at the axial center of the protective member 4. Furthermore, the first flange 42 is close to one side of the probe 21, and the radial profile size of the second flange 43 is larger than the radial profile size of the bite portion 41 and the first flange 42, and in order to facilitate the protective member 4 to be inserted into the patient's mouth, a chamfered portion 421 is provided on the outer side of the first figure element. When in use, first pass the first tube 2 through the through hole 44, and then put the protective member 4 into the patient's mouth, so that the patient's upper and lower teeth abut against the upper and lower sides of the occlusal portion 41, and the first flange 42 and the second flange 43 can effectively control the position to avoid excessive stuffing into the mouth or falling out of the mouth, and then continue to push the first tube 2 to the target area of ​​the throat to perform the suction operation.

[0041] Combination Figure 3 and Figure 4 As shown, anti-skid flanges 45 are provided on the upper and lower side walls of the through hole 44 in the area of ​​the bite portion 41. During the sputum suction process, if the patient does not cooperate and struggles, he or she will often bite the protective member 4 tightly, and the provision of the anti-skid flanges 45 enables the anti-skid flanges 45 to properly clamp and fix the first pipe member 2 when under pressure, thereby preventing the first pipe member 2 from falling off from the mouth due to the patient's struggling action, thereby facilitating the smooth sputum suction and ensuring the sputum suction effect.

[0042] Furthermore, one side of the probe 21 is provided with a plug-in portion 211 connected to the first pipe 2, and the other side is a suction operation end. The probe 21 is provided with an inner hole 212 axially connected to the first pipe 2. The inner hole 212 is provided with a plurality of suction holes connected to the external space at the suction operation end. Figure 5 As shown, the suction holes in this embodiment include a first suction hole 213 located on the front and a second suction hole 214 located on the side. This structure is conducive to the all-round suction operation of the working end of the probe 21, which can further improve the suction effect.

[0043] In other embodiments, in order to improve the intelligence of the equipment, a control system including a counting module and a communication module is provided on the cover body 12, which is a prior art, and its specific structure and working principle are not described here in detail. Those skilled in the art can select and implement from the prior art according to actual operating conditions. For example, a counter structure driven by an impeller is provided at the place where the first pipe 2 passes through the cover body 12 to accurately convert and measure the suction volume, and send the data to a mobile terminal, such as a mobile phone, computer, etc., through the communication module for easy viewing.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
