[0015] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0017] Example Please see Figures 1-8 This invention provides a medical aspiration device, including an aspiration component 1, a pus storage component 2, and a negative pressure generating component. The negative pressure generating component is connected to the pus storage component 2, and the pus storage component 2 is connected to the aspiration component 1. The aspiration component 1 extracts pus from the abscess site, and the pus storage component collects the extracted pus. The aspiration component 1 includes an aspiration head 12 and an incision component. The incision component is set on the aspiration head 12 to clean the surface of the abscess, facilitating the outflow of pus and the normal operation of the aspiration process.

[0018] Three incision components are provided, which are distributed circumferentially on the suction head 12. Each incision component includes a blade 11, which is located inside and on the upper part of the suction head 12. The incision is shallow, which can be easily used with the negative pressure generating device to suction pus, reducing the residue and blockage of pus in the abscess. A sealing element is provided at the connection between the blade 11 and the suction head 12. The blade 11 can easily break through the pus surface and expand the pus outflow area.

[0019] A medical soft silicone ring 13 is provided at the edge of the suction head 12. When the negative pressure is activated, a local negative pressure is formed inside the suction head 12, which tightly adheres the medical soft silicone ring 13 to the skin. At the same time, the softness of the silicone ring can avoid pressure sores caused by skin compression, and the sealing ensures that there will be no air leakage during the negative pressure suction process, maintaining a stable negative pressure environment.

[0020] The front end of the suction head 12 is set as a cylindrical structure, and the rear end of the suction head 12 is set as a cylindrical structure. The rear end of the suction head 12 is connected to the pus storage component 2. The pus storage component 2 includes a pus storage bottle 21 and a check valve. The check valve is set between the pus storage bottle 21 and the suction head 12. The end of the suction head 12 is provided with a trapezoidal thread 14 to connect with the check valve. The backflow of pus is prevented by the setting of the check valve.

[0021] The check valve and the pus collection bottle 21 are connected by threads. Rubber O-rings 15 are installed between the pus collection bottle 21 and the check valve, and between the check valve and the suction head 12, ensuring a tight seal. The double connection of threads and O-rings ensures airtightness. The pus collection bottle 21 is made of transparent material with graduation markings for easy and direct observation of the amount and characteristics of the pus, allowing for accurate measurement of the suctioned pus volume. Furthermore, disinfectant solutions such as iodine or anticoagulants such as heparin can be pre-placed in the container for thorough pus removal.

[0022] A filter screen 24 is installed at the connection end between the pus collection bottle 21 and the negative pressure generating component 3. The filter screen 24 is designed to filter pus clots and prevent blockage of the negative pressure conduit. The filter screen 24 is connected to the pus collection bottle 21 via a pressure ring 23. The end of the pus collection bottle 21 is provided with a filter screen mounting groove 22, which is threadedly connected to the pressure ring 23. The filter screen mounting groove 22 is designed as a stepped type. After the filter screen 24 is inserted, it is tightened by screwing the pressure ring 23 onto the internal thread of the filter screen mounting groove 22, pressing the filter screen 24 sealing gasket tightly onto the stepped surface, achieving a gapless seal around the filter screen 24 and preventing pus from bypassing the edge of the filter screen 24 and entering the conduit.

[0023] The negative pressure generating component 3 includes a telescopic motor 31 and a control unit. Doctors can precisely adjust the negative pressure intensity according to different abscess conditions, avoiding tissue damage due to excessive negative pressure or poor abscess suction due to insufficient negative pressure. The control unit is connected to the telescopic motor 31, which is connected to a push rod 33. The push rod 33 is located inside the negative pressure tube 34, which is connected to the abscess collection bottle 21.

[0024] The negative pressure generating component 3 has a negative pressure tube 34 and a negative pressure rod 32. The end of the negative pressure rod 32 is connected to the pull head 35, and the other end of the negative pressure rod 32 is set inside the negative pressure tube 34. The negative pressure tube 34 is also a pus collection bottle 21. The end of the negative pressure tube 34 is provided with a handle 36. By fixing it with the handle 36, the negative pressure rod 32 is pulled, and negative pressure is generated inside the negative pressure tube 34 to extract the pus.

[0025] Before using the suction device, medical staff should check that all components are securely connected and undamaged. Install the pus collection assembly 2 and ensure it is sealed. Set appropriate negative pressure parameters through the control unit; for initial use, the negative pressure can generally be set to around -200 mmHg. Slowly bring the suction head 12 close to the abscess, adjusting the angle according to the location and size of the abscess to ensure the suction head 12 is accurately aligned. Press down to allow the blade 11 to pierce the surface of the abscess, then lift it to activate the negative pressure generating component. The suction hole of the suction head 12 will begin to draw out the pus, which will flow into the pus collection bottle 21. During suction, the operator can observe the amount and characteristics of the pus in the collection bottle 21 and adjust the negative pressure as needed based on the patient's response. For example, if the pus is thick, the negative pressure can be increased; if the patient feels discomfort, the negative pressure can be decreased. After the suction operation is complete, turn off the negative pressure generating component. Disassemble the pus collection bottle 21 and dispose of it properly according to medical waste disposal regulations.

[0026] Therefore, this invention employs the aforementioned medical aspiration device, whose aspiration head can efficiently and comprehensively draw up pus, significantly shortening the aspiration time and improving treatment efficiency. The negative pressure generated can be precisely adjusted to suit different patients and abscess conditions, reducing the risk of tissue damage. It facilitates observation and cleaning; the transparent pus collection component and graduated markings allow medical staff to easily observe and measure the pus, and the convenient disassembly structure makes cleaning and disinfection easier.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
