[0028] Example:

[0029] Reference Figures 1-4The embodiment of the utility model provides a sputum suction tube device, comprising a shell A1 and a shell B2 threadedly connected thereto, and further comprising: a piston 3, mounted in the shell A1, wherein the shell B2 is provided with a driving portion for driving the piston 3 to slide in the shell A1; a connecting nozzle 5, mounted on the shell A1, wherein the shell A1 is provided with a connecting piece, the connecting nozzle 5 is connected to the shell A1 through the connecting piece, a sputum suction pipe 7 is clamped on the connecting nozzle 5, and the sputum suction pipe 7 is made of polyurethane, which has good elasticity and strength, while maintaining good flexibility to ensure the use effect of the sputum suction pipe 7; a sputum suction head 8, fixedly connected to the end of the sputum suction pipe 7, and the sputum suction head 8 is connected to the sputum suction pipe 7, and the sputum suction head 8 is made of hard plastic to facilitate its insertion into the patient's airway;

[0030] Among them, a plurality of suction holes 9 are provided on the suction head 8, the number of the suction holes 9 is 3-6, and 5 are preferably provided in this solution. Two blades 10 are fixedly installed in the suction holes 9, and the two blades 10 are staggered and formed into a cross shape.

[0031] Specifically, during use, through the setting of the driving part, negative pressure can be generated in the shell A1, and the sputum in the patient's airway can be sucked out and cleaned, and the cleaned sputum can be collected centrally through the collection cup 12, so as to facilitate the user's subsequent unified processing. In addition, through the setting of multiple suction holes 9, the sputum sucked into the suction pipe 7 can be diverted, and the diverted sputum can be divided by the blade 10, which can greatly reduce the probability of the suction pipe 7 being blocked due to the patient's sputum being too large and viscous, thereby improving not only the suction effect of the device, but also the care efficiency for the patient.

[0032] In order to generate negative pressure in the housing A, the driving part includes a pull rod 31 slidably mounted on the piston 3 , one end of the pull rod 31 is fixedly connected to a pull plate 33 , and the piston 3 is fixedly connected to the other end of the pull rod 31 .

[0033] Specifically, when in use, by pulling the pull plate 33 and the pull rod 31, the piston 3 is driven to slide in the shell A1, and at the same time the spring 32 is compressed, so that negative pressure is generated in the shell A1. Under the action of the negative pressure, sputum can be sucked into the shell A1. By loosening the pull plate 33, the piston 3 is reset under the elastic force of the spring 32, and the sputum can be discharged into the collection cup 12.

[0034] In order to transport sputum, the above-mentioned connecting piece is designed with the following scheme; the above-mentioned connecting piece includes a tube shell 4 and a drainage pipe 6, the tube shell 4 is connected to the shell body A1, the connecting nozzle 5 is connected to the tube shell 4, and the bottom of the tube shell 4 is connected to the drainage pipe 6, wherein a first one-way valve is fixedly installed at the connection between the tube shell 4 and the connecting nozzle 5, and a second one-way valve is fixedly installed at the connection between the tube shell 4 and the drainage pipe 6, and a collecting part is provided on the drainage pipe 6.

[0035] Specifically, through the arrangement of the tube shell 4 and the drainage tube 6, sputum can be transported, and through the first one-way valve, sputum can only enter the tube shell 4 in one direction from the connecting nozzle 5, and through the second one-way valve, sputum can only enter the drainage tube 6 in one direction from the tube shell 4.

[0036] The above-mentioned collecting part includes a connecting cover 11 and a collecting cup 12. The connecting cover 11 is connected to the bottom end of the drainage pipe 6. The collecting cup 12 is threadedly connected to the connecting cover 11. The connecting cover 11 is equipped with an air release valve 13. The above-mentioned structural design is for centralized collection of sputum.

[0037] Specifically, by connecting the cover 11 and the collection cup 12, the sucked sputum can be collected centrally, so as to facilitate the user's subsequent unified processing, and by setting the air release valve 13, the gas entering the collection cup 12 can be discharged.

[0038] In order to facilitate the user to pull the pull plate, the pull plate 33 is provided with a plurality of finger grooves 34 , and the plurality of finger grooves 34 are arranged linearly on the surface of the pull plate 33 .

[0039] Specifically, the provision of the finger groove 34 can facilitate the user to apply force, thereby facilitating the user to pull the pull plate 33 .

[0040] The housing B2 is fixedly connected with a handle 15, which is located at an end of the housing B2 away from the sputum suction pipe 7. Specifically, the arrangement of the handle 15 makes it easier for the user to take the device.

[0041] In order to assist in supporting the palm of the user, a limit block 16 is installed on the handle 15. The limit block 16 is fixedly connected to the side of the handle 15 away from the housing B2.

[0043] The connection between the sputum suction pipe 7 and the connecting nozzle 5 is covered with an elastic sleeve 17, and the material of the elastic sleeve 17 is rubber.

[0044] Specifically, by providing the elastic sleeve 17 , the sputum suction pipe 7 can be reinforced, so that the sputum suction pipe 7 is more firmly connected to the connecting nozzle 5 .

[0045] The collecting cup 12 is provided with a plurality of scale lines 14 , and the plurality of scale lines 14 are longitudinally arranged on the surface of the collecting cup 12 .

[0046] Specifically, the setting of the scale lines 14 can facilitate the user to observe the collection capacity of the sputum in the collection cup 12. The shape of the sputum suction head 8 is oval, and the surface of the sputum suction head 8 is smooth.

[0047] Specifically, such a design enables the suction head 8 to be inserted into the patient's airway more smoothly, thereby improving the suction effect of the device.

At the same time, the spring 32 is compressed to generate negative pressure in the shell A1. Under the action of the negative pressure, sputum enters the sputum suction head 8 through multiple sputum suction holes 9, and the sputum entering the sputum suction head 8 is divided by the blade 10. The divided sputum is sucked into the shell A1 through the sputum suction pipe 7, the connecting mouth 5 and the tube shell 4. Then the pull plate 33 is released, and the piston 3 is reset under the elastic force of the spring 32, so that the sputum is discharged into the collection cup 12 through the tube shell 4 and the drainage pipe 6.

[0049] The device can divert the sputum sucked into the sputum suction pipe 7 by setting multiple sputum suction holes 9 on the sputum suction head 8, and divide the diverted sputum by two blades 10 staggered in each sputum suction hole 9, which can greatly reduce the probability of the sputum suction pipe 7 being blocked due to the patient's sputum being too large and viscous, thereby improving not only the sputum suction effect of the device, but also the nursing efficiency of the patient, which is beneficial to the patient's rehabilitation treatment.
