Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically, to a handheld dual-channel ear cleaning and flushing operation instrument. Background Art

[0002] Ear cleaning and flushing are common otological treatment measures. For patients with secretory otitis media, tympanocentesis and flushing are effective measures to relieve symptoms. Usually, puncture is performed in the anterior inferior or posterior inferior quadrant of the tympanic membrane. After aspirating the middle ear effusion, drugs such as dexamethasone are injected into the middle ear to reduce the inflammatory reaction. In addition, for patients in the acute stage of chronic suppurative otitis media, cleaning the secretions and flushing the ear can effectively control the purulent symptoms, thereby providing an opportunity for middle ear surgery and improving the success rate of the surgery.

[0003] Ear flushing can usually be completed in the clinic. However, for some patients, pain and fear may cause difficulties or inappropriate operations during the procedure, especially when the currently used instruments need to repeatedly enter and exit the ear canal, which will prolong the treatment time and further increase the patient's fear. Therefore, reducing the number of operations of the instrument entering and exiting the ear canal and shortening the treatment time are necessary measures to improve the effectiveness of the operation and the sense of medical experience.

[0043] The following specifically describes the present utility model in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0044] The utility model provides a handheld dual-channel ear cleaning and flushing operation instrument, which includes a support shell 1, an air pump, and a dual-channel catheter 4. The support shell 1 has a handle end 11 and a connection end. An accommodation space is provided inside the support shell 1. The connection end is provided with a first connection port 12 and a second connection port 13. A first button 111 and a second button 112 are arranged on the handle end 11. The support shell 1 is preferably in a 7-shaped structure, similar to the shape of a pistol. The air pump is arranged in the accommodation space. When holding the handle end 11 and pressing the first button 111, the air pump starts and draws air from the first connection port 12 and the second connection port 13. When pressing the second button 112, the air pump starts and blows air into the first connection port 12 and the second connection port 13. The air pump in the utility model can be realized by controlling its forward or reverse rotation. For example, when pressing the first button 111, the air pump rotates forward, and when pressing the second button 112, the air pump rotates in reverse, achieving the effects of blowing or drawing air. It should be noted that the power supply of the air pump can be achieved in various ways. It can be powered by a rechargeable battery arranged inside the support shell 1, or designed to be powered by connecting to an external power source through a wire.

[0045] As Figure 1 shown, the dual-channel catheter 4 includes a first pipe 41, a second pipe 42, and a third pipe 43 respectively connected to the first pipe 41. The dual-channel catheter 4 is preferably in a Y-shaped structure. As Figure 2 shown, the second pipe 42 and the third pipe 43 are respectively connected to the first connection port 12 and the second connection port 13 through a first cylinder 2 and a second cylinder 3. Among them, a first one-way valve 421 and a second one-way valve 431 are respectively arranged in the second pipe 42 and the third pipe 43. The first one-way valve 421 allows fluid to flow from the first cylinder 2 to the second pipe 42, but does not allow reverse flow; the second one-way valve 431 allows fluid to flow from the third pipe 43 to the second cylinder 3, but does not allow reverse flow.

[0046] It should be noted that the first one-way valve 421 and the second one-way valve 431 can be designed to be detachably connected to the second pipe 42 and the third pipe 43 respectively, which can meet the requirement of replacing the one-way valve at any time when it is damaged.

[0047] Specifically, the first pipe 41, the second pipe 42, and the third pipe 43 are all of rigid structures. For the convenience of operation, the second pipe 42 and the first cylinder 2, and the third pipe 43 and the second cylinder 3 are both connected by disposable hoses, which neither affect the adjustment of the posture of the dual-channel catheter 4 nor affect the removal of the disposable hoses after use. When using it next time, a new disposable hose can be replaced.

[0048] Both the first measuring cylinder 2 and the first connection port 12, and the second measuring cylinder 3 and the second connection port 13 are detachably connected. The first measuring cylinder 2 and the second measuring cylinder 3 both include a syringe barrel 21 and a piston body 22 slidably arranged inside the syringe barrel 21. As Figure 3 shown, the two ends of the syringe barrel 21 are respectively a connection head 211 and an assembly head 212. The piston body 22 divides the interior of the syringe barrel 21 into a liquid storage space and a force application space. The liquid storage space is connected to the second pipeline 42 or the third pipeline 43 through the connection head 211, and the force application space is connected to the first connection port 12 or the second connection port 13 through the assembly head 212. In practical applications, when holding the handle end 11 by hand and pressing the first button 111, the air pump starts and draws air from the first connection port 12 and the second connection port 13. The force application space is in a negative pressure state, and the piston body 22 moves towards the end of the assembly head 212. The fluid is drawn into the liquid storage space through the connection head 211, thereby realizing the inhalation of the fluid. When pressing the second button 112, the air pump starts and blows air into the first connection port 12 and the second connection port 13. The piston body 22 moves towards the direction of the connection head 211, and the fluid in the liquid storage space is pushed out through the connection head 211, thereby realizing the output of the fluid.

[0049] To ensure the quality of use, a scale is provided on the syringe barrel 21, and the volume of the internal liquid can be directly read. In addition, when the hand holds the handle end 11 for use, the first connection port 12 and the second connection port 13 face directly downward. At this time, after installing the first measuring cylinder 2 or the second measuring cylinder 3, the measuring cylinder can be in the Figure 3 vertical state shown, which is beneficial to the operations of sucking and pushing out the fluid.

[0050] The working principle of the present utility model is as follows:

[0051] After clicking the first button 111, the air pump starts to draw air. A negative pressure lower than the atmospheric pressure is formed inside the second connection port 13, and a negative pressure state is simultaneously formed in the force application spaces of the first measuring cylinder 2 and the second measuring cylinder 3. However, the inside of the first pipeline 41 is in a positive pressure state. Since a first one-way valve 421 and a second one-way valve 431 are respectively arranged inside the second pipeline 42 and the third pipeline 43, the pus in the ear can only flow into the liquid storage space inside the second measuring cylinder 3 through the first pipeline 41 and the third pipeline 43, and will not flow into the first measuring cylinder 2 through the second pipeline 42 and be mixed with the liquid medicine, which can avoid contaminating the liquid medicine.

[0052] When the second button 112 is clicked, the air pump starts and blows air into the first connection port 12 and the second connection port 13. A positive pressure greater than the atmospheric pressure is formed in the force application spaces of the first measuring cylinder 2 and the second measuring cylinder 3. Due to the setting of the one-way valve, the piston body 22 in the first measuring cylinder 2 moves towards the connector 211, and the liquid medicine in the liquid storage space of the first measuring cylinder 2 is pushed out and enters the inner ear through the second pipeline 42 and the first pipeline 41 in sequence. However, since the second one-way valve 431 allows the fluid to flow from the third pipeline 43 to the second measuring cylinder 3 and does not allow reverse flow, the pus stored in the second measuring cylinder 3 will not enter the second pipeline 42 and the inner ear through the third pipeline 43, while the liquid medicine in the first measuring cylinder 2 can enter the second pipeline 42, the first pipeline 41 and then enter the inner ear through the first one-way valve 421.
