[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments; in the drawings or descriptions, similar or identical parts are denoted by the same reference numerals, and in actual applications, the shapes, thicknesses or heights of the components can be enlarged or reduced. The various embodiments listed in the present invention are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modification or change made to the present invention does not depart from the spirit and scope of the present invention.

[0032] Embodiment 1:

[0033] As Figures 1 - 4 shown, a sputum suction catheter disinfector provided by the present invention includes a catheter body 1, a disinfection cylinder 2 connected to the catheter body 1, and an ultraviolet lamp assembly disposed around the catheter body 1. The disinfection cylinder 2 is provided at one end of the catheter body 1 away from the sputum suction main body and is detachably and butt-connectedly connected to two sections of the catheter body 1. A ring seat 31 is coaxially and slidably disposed in the disinfection cylinder 2, a rotating shaft 32 is coaxially rotatably disposed on the ring seat 31, a plurality of obliquely disposed fan blades 33 are fixedly connected to the periphery of the rotating shaft 32, a plurality of liquid spraying holes 21 are provided on the inner wall of the disinfection cylinder 2, and the plurality of liquid spraying holes 21 are commonly connected to a disinfection bottle 22 filled with a disinfectant. A liquid supply mechanism for supplying liquid to the liquid spraying holes 21 is provided on the disinfection bottle 22. The liquid supply mechanism is a micro pump or an atomizing pump, and the liquid supply mechanism is connected to the plurality of liquid spraying holes 21 through a hose. Specifically, a connecting ring 26 is fixedly connected to the outer peripheral wall of the disinfection cylinder 2, an annular channel 27 communicating with the plurality of liquid spraying holes 21 is formed in the connecting ring 26, and the output end of the liquid supply mechanism is communicated with the annular channel 27 through a pipeline.

[0034] After being arranged like this, after connecting the catheter body 1 of the present application to the sputum suction device main body, when the sputum suction device is started, an air flow in the suction direction is generated in the catheter body 1. This air flow can drive the plurality of obliquely disposed fan blades 33 on the rotating shaft 32 to rotate on the ring seat 31. The rotating plurality of fan blades 33 can break the sputum in the catheter body 1 to a certain extent to increase the outer surface area of the sputum; at the same time, after starting the liquid supply mechanism to pump the disinfectant into the disinfection cylinder 2 through the plurality of liquid spraying holes 21, the disinfectant can be in full contact with the broken sputum to more fully kill the pathogenic bacteria in the sputum; then the ultraviolet light emitted by the ultraviolet lamp assembly can also perform secondary sterilization, effectively improving the disinfection effect of the disinfector of the present application on the inside of the sputum suction catheter.

[0035] Moreover, the rotation of the plurality of fan blades 33 on the rotating shaft 32 is driven by the suction force generated by the sputum suction device, without an external power source, which is easier to modify the existing sputum suction catheter, has a lower application cost, and is more suitable for popularization.

[0036] Specifically, referring to Figure 2 and Figure 3, a control mechanism for detecting the residual sputum volume inside and controlling the ring base 31 to shield and open multiple liquid spraying holes 21 is provided in the disinfection cylinder 2. Specifically, when the residual sputum volume in the disinfection cylinder 2 increases, the ring base 31 is automatically controlled to expose the liquid spraying holes 21 for disinfection operations. In actual setting, the control mechanism includes multiple control cylinders 41 fixedly connected to the circumferential side of the end of the rotating shaft 32. A counterweight column 42 is elastically connected inside the control cylinder 41. The counterweight column 42 is slidably arranged inside the control cylinder 41. Specifically, a second elastic member is fixedly connected between the counterweight column 42 and the side wall of the rotating shaft 32. The second elastic member is a tension spring.

[0037] And a slant groove 23 and an annular groove 24 communicating with each other are circumferentially formed on the inner peripheral wall of the disinfection cylinder 2;

[0038] When the counterweight column 42 aligns with the annular groove 24, the ring base 31 shields multiple liquid spraying holes 21;

[0039] When the counterweight column 42 aligns with the slant groove 23, the ring base 31 does not block the liquid spraying holes 21;

[0040] A first elastic member 34 for driving the ring base 31 to drive the counterweight column 42 to move away from the annular groove 24 is further provided in the disinfection cylinder 2. The first elastic member 34 is a tension spring embedded on the inner wall of the disinfection cylinder 2. The first elastic member 34 is located on the side of the ring base 31 facing the suction direction inside the catheter body 1.

[0041] After such setting, when the residual sputum in the disinfection cylinder 2 is less, or the sputum adhered to the fan blades 33 is less, the airflow sucked in the disinfection cylinder 2 can push the multiple fan blades 33 to drive the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it can drive the multiple control cylinders 41 to rotate accordingly. Then, the counterweight column 42 inside the control cylinder 41 moves away from the rotating shaft 32 under the action of its own centrifugal force. At this time, the counterweight column 42 abuts against the inclined surface of the slant groove 23. Thus, with the guiding effect of the slant groove 23, the ring base 31 can move towards the direction close to the annular groove 24 and finally keep the counterweight column 42 rotating in the annular groove 24 following the rotating shaft 32. In this state, the ring base 31 shields the liquid spraying holes 21 and pulls the first elastic member 34 to deform. At this time, there is no need to over-disinfect the small amount of sputum in the disinfection cylinder 2, and basic disinfection operations can be carried out relying on the ultraviolet lamp assembly.

[0042] Once there is a lot of residual sputum in the disinfection barrel 2, the resistance of the fan blade 33 to the rotation of the shaft 32 increases, so that the rotation speed of the shaft 32 decreases. At this time, the centrifugal force of the counterweight column 42 in the control barrel 41 is not enough to drive the ring seat 31 to overcome the elastic force of the first elastic member 34 and move toward the direction close to the ring groove 24, that is, the ring seat 31 does not cover the spray hole 21. At this time, the liquid supply mechanism can spray the disinfectant in the disinfection bottle 22 into the disinfection barrel 2 through the multiple spray holes 21 to fully disinfect the residual sputum, and realize the automatic start disinfection effect when the residual sputum in the disinfection barrel 2 is large. In addition, controlling the spray direction of the spray hole 21 and controlling the liquid supply pressure of the liquid supply mechanism can also achieve the flushing effect of the residual sputum on the fan blade 33.

[0043] At the same time, in order to achieve the self-start and stop effect of the liquid supply mechanism, in another feasible embodiment, a position switch, an infrared sensor, etc. can be installed in the disinfection cylinder 2 to detect the position of the ring seat 31, and the travel switch is controlled and connected with the liquid supply mechanism so that when the ring seat 31 moves to the alignment of the counterweight column 42 and the ring groove 24, the liquid supply mechanism is controlled to be closed, and when the ring seat 31 moves to the alignment of the counterweight column 42 and the inclined groove 23, the liquid supply mechanism is controlled to be started.

[0044] In order to prevent sputum from adhering to the outlet of the control cylinder 41 and affecting the moving effect of the counterweight column 42, Figure 2 and Figure 3 A shielding cylinder 43 for shielding the inclined groove 23 and the annular groove 24 is fixedly connected to the circumferential side of one end of the multiple control cylinders 41 away from the rotating shaft 32, and no matter the ring seat 31 moves to align with the counterweight column 42 with the annular groove 24 or with the inclined groove 23, the shielding cylinder 43 can shield the annular groove 24 and the inclined groove 23.

[0045] In addition, refer to Figure 1 and Figure 2 The above-mentioned ultraviolet lamp assembly includes a lamp holder 51 fixedly connected to the outer periphery of the disinfection tube 2 and an annular ultraviolet lamp 52 installed on the lamp holder 51. A reflector 53 surrounding the annular ultraviolet lamp 52 is fixedly connected to the lamp holder 51. The disinfection tube 2 can be made of transparent hard plastic such as PE or PEEK; and both ends of the disinfection tube 2 are fixedly connected with pagoda connectors 25 for connecting to the catheter body 1 to facilitate the installation and disassembly of the disinfection tube 2.

[0046] Embodiment 2:

[0047] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that:

[0048] The inner wall of the annular seat 31 is arranged in a converging shape along the suction direction inside the catheter body 1, so that the sputum passing through the annular seat 31 can preferably cross the positions where the annular groove 24 and the inclined groove 23 are located, reducing the influence on the moving performance of the counterweight column 42 in the control cylinder 41. Moreover, a plurality of cutting blades 311 arranged along its axis are fixedly connected to the inner wall of the annular seat 31. The plurality of cutting blades 311 protrude from the inner wall of the annular seat 31 and are circumferentially arrayed at equal intervals around the axis of the annular seat 31. There is a gap between the outer periphery of the fan blade 33 and the cutting blade 311.

[0049] After such setting, even if the sputum passing through the disinfection cylinder 2 is scattered under the action of the rotating plurality of fan blades 33, the converging annular seat 31 can gather the outward-expanding sputum to a certain extent, so that the disinfectant liquid sprayed from the liquid spraying holes 21 can be mixed more fully with the sputum, ensuring the disinfection effect; at the same time, the setting of the plurality of cutting blades is also to further promote the separation of the agglomerated sputum, so that the sputum can better contact with the disinfectant liquid, and can also improve the disinfection effect to a certain extent.

[0050] The specific working effect of the present invention is as follows:

[0051] After connecting the catheter body 1 of the present application to the sputum aspirator main body and starting the sputum aspirator, the airflow generated in the catheter body 1 can drive the plurality of fan blades 33 inclinedly arranged on the rotating shaft 32 to rotate on the annular seat 31. The rotating plurality of fan blades 33 can break the sputum in the catheter body 1 to a certain extent to increase the outer surface area of the sputum; at the same time, after starting the liquid supply mechanism to pump the disinfectant liquid into the disinfection cylinder 2 through the plurality of liquid spraying holes 21, the disinfectant liquid can be in full contact with the broken sputum to more fully kill the pathogenic bacteria in the sputum; then the ultraviolet light emitted by the ultraviolet lamp assembly can also perform secondary sterilization, effectively improving the disinfection effect of the disinfector of the present application on the inside of the sputum aspiration catheter.

[0052] Moreover, the rotation of the plurality of fan blades 33 on the rotating shaft 32 is driven by the suction force generated by the sputum aspirator, without an additional power source, which is easier to modify the existing sputum aspiration catheter, with a lower application cost and more suitable for popularization.
