[0031] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0032] Currently, the commonly used percussion head on the market is an eccentric wheel percussion head. The principle is to transmit the force inside the sputum removal machine to the eccentric wheel mechanism of the percussion head through a flexible shaft, and the percussion head generates vibration through the mechanism of the eccentric wheel. This mechanical transmission method of the percussion head has more parts and higher costs. Moreover, mechanical transmission will generate relatively large noise, which will have a greater impact on patients. In addition, the transmission method using the eccentric wheel mechanism results in a relatively large assembly gap between parts, which will generate relatively large noise, and there are many machined parts in the eccentric wheel, resulting in an increase in the overall weight of the sputum removal percussion head.

[0033] Please refer to Figures 1 to 4 , and now the sputum removal percussion head provided by the present utility model will be described. The sputum removal percussion head is used for a sputum removal machine. The sputum removal percussion head includes a treatment assembly 1 and a pipeline assembly 2. The treatment assembly 1 includes a handle 11, a treatment head 12, and a ventilation piston 13. The handle 11 is provided with a receiving groove 112, as well as a working port 113 and a ventilation channel 111 that communicate with the receiving groove 112. The treatment head 12 is installed in the receiving groove 112 and can extend out of the working port 113. The ventilation piston 13 includes a housing 131 and a piston rod 133 that is slidably connected inside the housing 131. The housing 131 is installed in the receiving groove 112, and the piston rod 133 is connected to the treatment head 12. The pipeline assembly 2 is installed in the ventilation channel 111 and communicates with the inner cavity of the housing 131. During the process of the pipeline assembly 2 ventilating the inner cavity of the housing 131, the piston rod 133 can perform telescopic movement inside the housing 131, and the telescopic movement of the piston rod 133 can drive the treatment head 12 to perform telescopic movement.

[0034] It can be understood that the treatment head 12 of this sputum removal percussion head is installed in the receiving groove 112 and can extend out of the working port 113. The housing 131 is installed in the receiving groove 112, the piston rod 133 is connected to the treatment head 12, the pipeline assembly 2 is installed in the ventilation channel 111 and communicates with the inner cavity of the housing 131. During the process of the pipeline assembly 2 ventilating the inner cavity of the housing 131, the piston rod 133 can perform telescopic movement inside the housing 131, and the telescopic movement of the piston rod 133 can drive the treatment head 12 to perform telescopic movement, enabling the treatment head 12 to achieve the percussion function. Compared with the existing eccentric wheel percussion head, the pneumatic percussion method has lower noise, thereby improving the patient experience.

[0035] In addition, compared with the sputum removal percussion head of the prior art, most of the percussion heads in the prior art are eccentric wheel mechanisms. This transmission method requires a relatively large counterweight, and a too heavy percussion head will affect the doctor's use experience. Therefore, the pneumatic percussion method has a simple structure, the sputum removal percussion head is relatively light, and the doctor's use experience is improved.

[0036] It should be noted that the utility model is suitable for an expectorant with an air vibration expectoration function. The air vibration expectoration function is achieved by simulating the normal physiological coughing process. The treatment component 1 is connected to a high-speed pulse pump with a pipeline component 2. After rapid inflation and deflation of the high-speed pulse pump, the treatment component 1 is placed on the patient's chest or back. The treatment head 12 at the front of the treatment component 1 causes the patient's chest wall to undergo regular relaxation movements. The patient's airway and lungs produce autonomous vibration airflow and directional drainage force, which promotes the relaxation, liquefaction, and shedding of respiratory mucus and deep metabolites of each lung lobe, and discharges them from the body under the action of the directional drainage force. This technology is called "chest wall oscillation technology."

[0037] In this embodiment, the vent piston 13 further includes a plug connector 132, which is connected to the housing 131 and plugged with the pipeline assembly 2 to connect the inner cavity of the housing 131 with the inner cavity of the pipeline assembly 2. By providing the plug connector 132, the housing 131 can be more firmly connected to the pipeline assembly 2.

[0038] In one embodiment, the plug connector 132 may be a protrusion disposed on the housing 131 , and the protrusion is interference fit with the inner wall of the pipe assembly 2 , so that the housing 131 can be stably connected to the pipe assembly 2 .

[0039] In another embodiment, the plug connector 132 may be a snap-fit ​​groove provided on the shell 131 , and the pipeline assembly 2 is provided with a buckle, and the buckle and the groove wall of the snap-fit ​​groove are snap-fitted, so that the shell 131 can be stably connected to the pipeline assembly 2 .

[0040] In one embodiment, if Figure 2 and Figure 3 As shown, the treatment head 12 is a structural member made of silicone rubber material. In this way, the treatment head 12 made of silicone rubber material can be softer during operation, and is more comfortable to contact with the human body without causing damage to the human body, thereby increasing the user experience.

[0041] In this embodiment, the head of the piston rod 133 is rubber-encapsulated in the treatment head 12. Specifically, the treatment head 12 has a connection groove 121, and the head of the piston rod 133 is arranged in the connection groove 121. Since the treatment head 12 is a structural member made of silicone rubber material, the head of the piston rod 133 can be firmly fixed to the treatment head 12, and the telescopic movement of the piston rod 133 can drive the telescopic movement of the treatment head 12, thereby increasing the reliability of the treatment head 12.

[0042] Further, the treatment assembly 1 further includes an adhesive member. The treatment head 12 is provided with an elastic connecting member 122. The groove wall of the accommodating groove 112 is provided with a mounting groove 114. The elastic connecting member 122 is inserted into the mounting groove 114. The adhesive member is filled in the mounting groove 114 and is used to connect the elastic connecting member 122 with the groove wall of the mounting groove 114. Specifically, the adhesive member can be a strong glue. By providing the adhesive member, the elastic connecting member 122 can be connected to the groove wall of the mounting groove 114, so that the assembly of the treatment head 12 is simple and the installation efficiency of the staff is improved. By providing the mounting groove 114, the elastic connecting member 122 can increase the connection area with the adhesive member, thereby improving the connection stability of the elastic connecting member 122.

[0043] In one embodiment, continue as Figure 2 and Figure 3 shown, the handle 11 is a structural member made of plastic material. The handle 11 is processed from plastic material, which can reduce the overall weight of the sputum drainage percussion head, making it more convenient for doctors during use. Prolonged use will not increase the fatigue of the doctor's wrist, thereby improving the doctor's usage experience.

[0044] In one embodiment, as Figure 2 and Figure 4 shown, the pipeline assembly 2 includes an air duct 21 and a sheath 22. The sheath 22 is sleeved on the air duct 21. One end of the air duct 21 is communicated with the ventilation piston 13, and the other end is used to be communicated with a high-speed pulse pump. Specifically, the air duct 21 and the sheath 22 are integrally formed by extrusion of soft rubber of different materials. The hardness of the soft rubber material of the sheath 22 is greater than that of the soft rubber material of the air duct 21. The harder sheath 22 can effectively protect the internal air duct 21.

[0045] In this embodiment, the pipeline assembly 2 further includes a clamp 23. The clamp 23 can be sleeved on the sheath 22 and press the sheath 22 and the air duct 21 onto the ventilation piston 13. By providing the clamp 23, the sheath 22 and the air duct 21 can be stably installed on the ventilation piston 13, thereby preventing the sheath 22 and the air duct 21 from falling off the ventilation piston 13.

[0046] Further, the pipeline assembly 2 further includes a pipe sleeve 24. The pipe sleeve 24 is sleeved on the sheath 22, and the pipe sleeve 24 is threadedly connected to the inner wall of the ventilation passage 111. Specifically, the pipe sleeve 24 is formed of soft rubber material. By sleeving the pipe sleeve 24 on the sheath 22 and connecting it to the inner wall of the ventilation passage 111, the bending radius of the air duct 21 can be increased, so that the air duct 21 is not easily bent and damaged, thereby effectively protecting the air duct 21.

[0047] In one embodiment, the sleeve 24 has external threads, and the inner wall of the ventilation passage 111 has internal threads. The external threads are threadedly connected to the internal threads, so that the sleeve 24 can be installed on the inner wall of the ventilation passage 111.

[0048] The present utility model also provides a sputum aspirator, which includes the sputum aspiration percussion head of any one of the above embodiments.

[0049] In this embodiment, the sputum aspirator of the present utility model uses the above-mentioned sputum aspiration percussion head, so that

[0050] The treatment head 12 of the sputum aspiration percussion head is installed in the accommodation groove 112 and can extend out of the working port 113. The housing 131 is installed in the accommodation groove 112. The piston rod 133 is connected to the treatment head 12. The pipeline assembly 2 is installed in the ventilation passage 111 and is communicated with the inner cavity of the housing 131. During the process of ventilating the inner cavity of the housing 131 by the pipeline assembly 2, the piston rod 133 can perform telescopic movement in the housing 131. The telescopic movement of the piston rod 133 can drive the treatment head 12 to perform telescopic movement, so that the treatment head 12 realizes the percussion function. Compared with the existing eccentric wheel percussion head, the pneumatic percussion method has lower noise, thereby improving the patient experience.

[0051] In addition, compared with the sputum aspiration percussion head of the prior art, most of the percussion heads in the prior art are eccentric wheel mechanisms. This transmission method requires a large counterweight. If the percussion head is too heavy, it will affect the doctor's use experience. Therefore, the pneumatic percussion method is adopted, which has a simple structure and the sputum aspiration percussion head is lighter in weight, improving the doctor's use experience.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
