It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the utility model provides a sputum suction device, include negative pressure ball 1, inhale phlegm pipe 2 and three-way valve 3, three-way valve 3's import 31 with inhale phlegm pipe 2 and be linked together, be connected with negative pressure ball 1 on three-way valve 3's first export 32 and/or the second export 33, the gas circuit between import 31 and the first export 32 and the gas circuit between import 31 and the second export 33 block and open through three-way valve 3's control valve clack. The suction pressure is provided by adopting the negative pressure ball 1, so that the sputum suction step is greatly simplified, when the sputum suction device is used, the negative pressure is formed by extruding the negative pressure ball 1, the sputum is sucked out to one negative pressure ball 1 through the sputum suction pipe 2, when the negative pressure ball 1 connected to the first outlet 32 works, the air passage between the second outlet 33 and the inlet 31 needs to be blocked, the sucked sputum can only enter the negative pressure ball 1 connected to the first outlet 32 through the air passage between the inlet 31 and the first outlet 32, when the sputum in the negative pressure ball 1 is full, the air passage between the first outlet 32 and the inlet 31 is blocked, the air passage between the second outlet 33 and the inlet 31 is opened, the sucked sputum can only enter the negative pressure ball 1 connected to the second outlet 33 through the air passage between the inlet 31 and the second outlet 33, more sputum can be sucked, and the sputum suction device is more convenient to use, the sputum suction device can be operated by one hand, and the sputum suction time and the intermittence time can be conveniently controlled in the using process; the negative pressure can be formed by continuous extrusion without a power supply, and the negative pressure value is always in a safe range, so that the use is very safe; and the structure is simple, the manufacture is convenient and the cost is low. Additionally, the utility model provides a negative pressure ball and inhale preferably adopt between phlegm pipe and the three-way valve to dismantle and be connected, be convenient for like this change negative pressure ball and inhale the phlegm pipe, but the three-way valve reuse saves the resource, practices thrift the cost.

Inhale and seted up in the middle part of the terminal surface of keeping away from three-way valve 3 on the phlegm pipe 2 and inhale the phlegm hole, inhale and seted up the supplementary phlegm hole 4 of inhaling on the lateral wall of keeping away from the tip of three-way valve 3 on the phlegm pipe 2, the supplementary phlegm hole 4 of inhaling's setting has improved and has inhaled the phlegm effect for it is less to remain the sputum, and the drainage is unobstructed.

As an optional implementation mode, the number of the auxiliary sputum suction holes 4 in the embodiment is 3-4, and the auxiliary sputum suction holes 4 are uniformly arranged around the circumference of the sputum suction tube 2 at intervals. The auxiliary sputum suction hole 4 is circular and the diameter of the auxiliary sputum suction hole 4 is 1-2 mm.

As an optional implementation, the sputum suction tube 2 comprises a sputum suction tube 2 body and a head end, the sputum suction tube 2 body and the head end are both of a fixed connection or an integrated structure, and preferably, the sputum suction tube 2 body and the head end are integrated, so that the cost of the mold can be saved, and the cost can be reduced. The head end sets up the one end of keeping away from three-way valve 3 on inhaling phlegm pipe 2 body, has seted up supplementary phlegm hole 4 of inhaling on the head end.

Considering that the injury of oral mucosa of the conventional negative pressure sputum suction of the conventional sputum suction apparatus can reach 8.6%, the tip 5 at the head end of the sputum suction tube 2 is designed into a round and smooth structure, so that the trachea of a patient can be effectively protected, and the injury rate of the oral mucosa is reduced.

As an optional implementation mode, the sputum suction hose body is made of medical PVC materials, and the head end is made of starch-based bioplastic or silica gel. The user inserts the sputum suction tube 2 into the respiratory tract of a patient, the head end of the sputum suction tube 2 is starch-based bioplastic or silica gel which can be softened when meeting water, and the material can be softened when meeting water, so that the discomfort and foreign body sensation of the patient are obviously reduced, and the sputum suction tube is particularly suitable for infants. In addition, the negative pressure ball 1 in the utility model can be used repeatedly after disinfection, and the suction tube is disposable, so as to avoid cross infection; is not only suitable for neonate to suck phlegm, but also suitable for children and adults.

As an optional embodiment, a first one-way valve is arranged between the sputum suction pipe 2 and the inlet 31, and a second one-way valve is arranged on the negative pressure ball 1. In addition, the surface of the negative pressure ball 1 is provided with scale marks, and the negative pressure ball 1 adopts a transparent suction ball. Therefore, when the negative pressure ball 1 is pressed, the scale mark position reached by the rear end of the negative pressure ball 1 can be clearly seen, so that the operation is more convenient, the force during the pressing operation can be ensured to be in a controllable range, and the pressure requirement in the negative pressure ball 1 is less than 300mmhg when the negative pressure ball is used for a newborn or an infant. When used by children or adults, the negative pressure ball 1 with different pressure ranges can be replaced. When the sputum suction device is used specifically, the sputum suction tube 2 is slowly conveyed into the oral cavity and the nasal cavity of a patient, and then the negative pressure ball 1 is pressed to start to suck sputum. The surface of the negative pressure ball 1 is provided with scale lines and is a transparent suction ball, so that the condition of the sucked liquid is conveniently observed and measured. Simultaneously, because be provided with first check valve and second check valve on the sputum suction device, so can press many times and absorb the sputum in, still guaranteed that the sputum in the negative pressure ball 1 can not flow out.

In addition, the sputum suction tube 2 of the embodiment is further provided with a protective cover 6, and the protective cover 6 can slide along the axial direction of the sputum suction tube 2, so that the medical staff can be prevented from being infected by the substance choked.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention.
