[0038] The present utility model provides an ENT aspirator and its suction head that are easy to disassemble, as Figures 1 to 4 shown, aiming to solve the problems that in the prior art, it is time-consuming and laborious to manually push out the aspirator and the suction head, and there is an easy risk of iatrogenic infection.

[0039] An ENT aspirator that is easy to disassemble includes a first housing 100, a second housing 200, and a pushing assembly. One end of the first housing 100 is provided with a suction connector 140, and the suction connector 140 is in the shape of a sleeve. The suction connector 140 is used for inserting the suction head 300; the other end of the first housing 100 is provided with a tracheal connector 110, and the tracheal connector 110 is also in the shape of a sleeve. The tracheal connector 110 is used for detachably connecting with a suction device 500; see Figure 1 shown, the front end of the first housing 100 is conical, and the rear end is cylindrical, and the whole is in the shape of a bullet. A cavity is provided inside the first housing 100, and the cavity is used to communicate the suction connector 140 and the tracheal connector 110, so that the suction device 500 can pass gas through the tracheal connector 110 and suck objects through the suction head 300 on the suction connector 140; the second housing 200 is arranged on the first housing 100, and a channel 220 is provided on the second housing 200. The second housing 200 is used for installing the pushing assembly; the pushing assembly is slidably arranged in the channel 220, and the pushing assembly extends along the axial direction of the first housing 100, and the end is connected to the suction connector 140. The pushing assembly is used to push the suction head 300 along the axial direction of the first housing to separate the suction connector 140.

[0040] It should be noted that both the first housing 100 and the second housing 200 are made of heat-resistant materials, such as metal stainless steel and plastic polypropylene (PVC), to facilitate high-temperature disinfection and repeated use. The first housing 100 can be cylindrical or rectangular. In this embodiment, the first housing 100 is preferably cylindrical.

[0041] In the above embodiments, by providing the second housing 200 on the first housing 100 and providing a pushing component on the second housing 200, and the pushing component is connected to the suction joint 140, the pushing component is used to push the suction head 300 to disengage from the suction joint 140, so as to realize contactless pushing of the suction head 300, avoid iatrogenic infection caused by direct contact with the suction head 300, reduce the replacement time, and improve work efficiency.

[0042] In some embodiments, as Figures 1 to 3 shown, the pushing component includes a push rod 410, a connecting rod 440, a push ring 450 and a spring 430. The push rod 410 is movably arranged on the channel 220. A contact block 420 is arranged on the push rod 410, and the contact block 420 is located in the channel 220; one end of the connecting rod 440 is arranged on the push rod 410; the push ring 450 is arranged at the other end of the connecting rod 440 and sleeved on the suction joint 140 for abutting and pushing the suction head 300; the spring 430 is sleeved on the push rod 410, one end is connected to the inner wall of the channel 220, and the other end abuts against the contact block 420.

[0043] In specific implementation, as Figure 2 and Figure 3 shown, taking the left side and the right side of Figure 2 as an example, the pushing component includes a push rod 410, a connecting rod 440, a push ring 450 and a spring 430. When a medical staff presses the push rod 410, the contact block 420 on the push rod 410 compresses the spring 430, and the spring 430 stores elastic potential energy under the action of an external force. The push rod 410 extends out of the left side of the channel 220, that is, a corresponding through hole is opened on the left side of the channel 220 for the push rod 410 to extend out, driving the connecting rod to move to the left, and the push ring 450 on the connecting rod also moves to the left. The push ring 450 abuts against the suction head 300 and pushes the suction head 300 to disengage from the suction joint 140, so as to realize contactless pushing of the suction head 300; when the medical staff releases the pressed hand, the elastic potential energy of the spring 430 is released to urge the push rod 410 to return to the right, driving the connecting rod 440 and the push ring 450 to return to the right. At this time, there is still a large part of the space on the suction joint 140 for the suction head 300 to be inserted, so as to avoid affecting the insertion effect of the suction head 300 on the suction joint 140; when the medical staff needs to use the device again, only need to insert the suction joint 140 into the corresponding suction head 300 and repeat the above steps.

[0044] It can be understood that the diameter of the connecting rod 440 is smaller than the diameter of the push rod 410. The connecting rod 440 is of an irregular shape and does not contact the outer wall of the first housing 100 to avoid affecting the moving path of the connecting rod 440.

[0045] Furthermore, in some embodiments, as Figure 2As shown, a handwheel 460 is provided at one end of the push rod 410 facing away from the connecting rod 440, and the handwheel 460 is detachably connected to the push rod 410. Specifically, the handwheel 460 is cylindrical in shape, and the handwheel 460 is threadedly connected to the push rod 410. The diameter of the handwheel 460 is larger than that of the push rod 410 to increase the contact area of the medical staff's hand, making it more comfortable for the medical staff to press the push rod 410.

[0046] Furthermore, in another embodiment, a soft pad is provided at one end of the handwheel 460 facing away from the push rod 410, and the soft pad is adhesively connected to the handwheel 460. Specifically, in this embodiment, the soft pad is adhesively connected to the handwheel 460, such as by double-sided tape, glue, Velcro, etc. The soft pad is not shown in the figure. More specifically, the soft pad and the handwheel 460 are preferably connected by Velcro for easy replacement; when the medical staff presses the handwheel 460, they first contact the soft pad and then the handwheel 460, further improving the comfort when pressing the push rod 410.

[0047] In some embodiments, as Figure 1 shown, an airtight groove 120 is provided on the first housing 100, and the airtight groove 120 communicates with the cavity. When the suction device 500 sucks air through the first housing 100, due to the existence of the airtight groove 120, holding the airtight groove 120 can cause the lesion to be sucked into the suction device 500 through the suction head 300 and the first housing 100. At this time, the suction force is the largest; when the airtight groove 120 is not completely covered, at this time, the suction force will be diverted by the airtight groove 120, so that the size of the suction force can be adjusted by the covering size of the airtight groove 120, and the adjustment is quick and convenient.

[0048] Further, in some embodiments, as Figure 1 shown, the cross-sectional shape of the airtight groove 120 is teardrop-shaped to conform to the finger shape of the medical staff, making it more convenient for the medical staff to press and facilitating the adjustment of the suction force of the aspirator, improving the operation convenience and accuracy.

[0049] Furthermore, in some embodiments, as Figure 1 shown, a flat portion 130 is provided on the first housing 100, the flat portion 130 is a smooth plane, and the airtight groove 120 is provided on the flat portion 130.

[0050] In specific implementation, the first housing 100 is cylindrical in shape and the surface is an arc surface. When pressing, due to the easy existence of gaps on the arc surface, the airtight groove 120 cannot be completely covered. Based on this, when the medical staff presses on the airtight groove 120, since the smooth plane is provided on the first housing 100, the fingers of the medical staff can completely fit on the flat portion 130, and there are no gaps easily when pressing, further improving the operation convenience.

[0051] In some embodiments, such as Figure 1 and Figure 2 shown, a fixator 210 is provided on the second housing 200. The fixator 210 is arranged to be bent at a predetermined angle. The fixator 210 is in the shape of a bent hook, which is used to facilitate medical staff to pick up the first housing 100. The fixator 210 is made of a metal material, such as stainless steel, to improve toughness and strength.

[0052] In some embodiments, a threaded portion is provided on the tracheal connector 110. The threaded portion is threadedly connected to the suction device 500. It can be understood that, as Figure 4 shown, the suction pipe of the suction device 500 is also provided with a thread corresponding to the threaded portion, so that the first housing 100 can be threadedly connected and installed with the suction device 500, and the disassembly is convenient.

[0053] The present utility model also provides a suction head 300, which includes the otorhinolaryngology aspirator described in any one of the above embodiments. The suction head 300 is connected to the otorhinolaryngology aspirator, as specifically described above.

[0054] It should be noted that the suction head 300 and the inhalation connector 140 of the otorhinolaryngology aspirator are in a plug-and-play connection manner, and those skilled in the art can select and set according to actual needs.

[0055] The suction head 300 provided by the present utility model has all the above beneficial effects because it is provided with the otorhinolaryngology aspirator described in any one of the above technical solutions, and will not be elaborated here.

[0056] In summary, the present utility model provides an otorhinolaryngology aspirator and its suction head that are easy to disassemble. By providing a second housing on the first housing and providing a pushing assembly on the second housing, the pushing assembly is used to push the suction head to disengage from the inhalation connector, so as to realize non-contact pushing out of the suction head, avoid iatrogenic infection caused by direct contact with the suction head, reduce the replacement time, and improve work efficiency; by providing an airtight groove, the magnitude of the suction force can be manually adjusted to improve the operation convenience; by providing a fixator, it is convenient to grasp the first housing and the use is more convenient.

[0057] It should be understood that the application of the present utility model is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
