技术领域Technical field
本申请涉及医用牙椅领域，具体而言，涉及一种带有干式水气分离装置的医用牙椅。The present application relates to the field of medical dental chairs, specifically, to a medical dental chair with a dry water and gas separation device.
背景技术Background technique
医用牙椅是牙科口腔手术及口腔疾病检查和治疗中不可或缺的医用器械，医用牙椅在工作时，需要将口腔内液体进行吸附排出口腔外部，因此牙椅内部包含了多组复杂水路管道及相关气动管道、水路管道，长时间的使用容易存在残留液，会滋生细菌或者生物膜附着在管道内，易对患者和医生造成感染、危害健康。The medical dental chair is an indispensable medical instrument in dental oral surgery and oral disease examination and treatment. When the medical dental chair is working, it needs to adsorb intraoral fluid and discharge it from the outside of the mouth. Therefore, the interior of the dental chair contains multiple sets of complex water pipes. And related pneumatic pipelines and water pipelines. After long-term use, residual liquid is likely to exist, which can breed bacteria or biofilm attached to the pipelines, which can easily cause infection and harm the health of patients and doctors.
现有的牙科治疗椅使用的抽吸方式多为负压抽吸方式，由于负压抽吸的管路与牙科手机是连通的，因此在每次强弱吸手机使用完毕之后，含有患者口腔内部病菌飞沫的气体，都会受到强弱吸手机的回吸，排入到诊室整体环境中，增加了交叉感染的风险。Most of the suction methods used in existing dental treatment chairs are negative pressure suction. Since the negative pressure suction pipeline is connected to the dental handpiece, after each use of the strong and weak suction handpiece, it contains the inside of the patient's mouth. The gas droplets of germs will be sucked back by strong and weak suction phones and discharged into the overall environment of the clinic, increasing the risk of cross-infection.

It should be noted that, In the initial state, the sealing state is between the plug 84 and the air inlet 722 .
进一步的，挡板844的位移长度和密封块83的位移长度一致，确保了密封块83和堵头84同时发生位移。Furthermore, the displacement length of the baffle 844 is consistent with the displacement length of the sealing block 83, ensuring that the sealing block 83 and the plug 84 are displaced simultaneously.
下面参考附图描述根据本申请实施例的一种带有干式水气分离装置的医用牙椅的使用过程：The following describes the use process of a medical dental chair with a dry water vapor separation device according to an embodiment of the present application with reference to the accompanying drawings:
使用的时候，通过外接负压设备向负压舱72内提供吸力，此时因堵头84和进气嘴722处形成密封，故负压舱72靠近单向阀721的一侧吸力增大，在吸力作用下，将迫使密封块83沿着导向杆82向挡块81方向位移，而挡板844的位移长度和密封块83的位移长度一致，故密封块83将直接带动挡板844进行位移，即带动堵头84沿T形槽723位移，此时堵头84和进气嘴722之间密封状态解除，干式过滤器6和强弱吸手机5之间形成连通的通路，强弱吸手机5可完成对患者口腔内液体的吸取，并传输向干式过滤器6，由干式过滤器6进行处理，并将含有病菌的液体通过排水管62排向下水道内，当对患者口腔内处理完成之后，将强弱吸手机5卡接在微动开关41上，此时强弱吸手机5停用，同时关闭外接负压设备，在单向阀721的作用下，此时负压舱72并不能从干式过滤器6方向回吸，而在负压舱72内，位于远离单向阀721的一端，因密封块83向挡块81方向的位移，造成该处空腔内产生新的负压，而外接负压停止以后，且负压舱72和过滤舱73之间此时为连通状态，故在此负压作用下，将迫使密封块83复位，继而对过滤舱73内造成新的吸力，直至堵头84重新和进气嘴722之间形成密封状态为止，而此吸力，将会使得进路管71和强弱吸手机5内部残留的含有病菌的飞沫被吸取向过滤舱73以及负压舱72内部，避免了因强弱吸手机5停用而造成回流，使得含有病菌的飞沫弥漫向治疗空间内，增加交叉感染的风险。When in use, external negative pressure equipment is used to provide suction into the negative pressure chamber 72. At this time, since the plug 84 and the air inlet 722 form a seal, the suction force increases on the side of the negative pressure chamber 72 close to the one-way valve 721. Under the action of suction, the sealing block 83 will be forced to move along the guide rod 82 in the direction of the stopper 81, and the displacement length of the baffle 844 is consistent with the displacement length of the sealing block 83, so the sealing block 83 will directly drive the baffle 844 to move. , that is, the plug 84 is driven to move along the T-shaped groove 723. At this time, the sealing state between the plug 84 and the air inlet 722 is released, and a connected passage is formed between the dry filter 6 and the strong and weak suction handpiece 5. The mobile phone 5 can complete the absorption of the liquid in the patient's oral cavity, and transmit it to the dry filter 6, which will process it, and discharge the liquid containing bacteria into the sewer through the drain pipe 62. When the liquid in the patient's oral cavity is After the processing is completed, the strong and weak suction handpiece 5 is connected to the micro switch 41. At this time, the strong and weak suction handpiece 5 is deactivated, and the external negative pressure equipment is closed at the same time. Under the action of the one-way valve 721, the negative pressure chamber 72 cannot suck back from the direction of dry filter 6, and in the negative pressure chamber 72, located at the end far away from the one-way valve 721, due to the displacement of the sealing block 83 towards the stopper 81, new fluid is generated in the cavity there. After the external negative pressure stops, and the negative pressure cabin 72 and the filter cabin 73 are connected at this time, the sealing block 83 will be forced to reset under the action of this negative pressure, which will cause damage to the filter cabin 73. The new suction force is until a sealing state is formed between the plug 84 and the air inlet 722, and this suction force will cause the droplets containing germs remaining inside the inlet pipe 71 and the strong and weak suction handpiece 5 to be sucked toward the filter. The interior of the cabin 73 and the negative pressure cabin 72 avoids backflow caused by deactivation of the strong and weak suction devices 5, causing droplets containing germs to diffuse into the treatment space and increase the risk of cross-infection.
在相关技术中，该一种带有干式水气分离装置的医用牙椅，在对患者口腔内液体进行吸取的时候，难免会因患者口腔内含有异物，而导致异物和液体一起被吸向干式过滤器6方向，如不对异物进行处理，可能会导致强弱吸手机5到干式过滤器6之间的管道产生堵塞，影响该医用牙椅的正常使用。In the related art, when this kind of medical dental chair with a dry water vapor separation device sucks the liquid in the patient's oral cavity, it is inevitable that the foreign body will be sucked together with the liquid because the patient's oral cavity contains foreign matter. In the direction of dry filter 6, if foreign matter is not dealt with, the pipeline between the strong and weak suction handpiece 5 and the dry filter 6 may be blocked, affecting the normal use of the medical dental chair.

具体的，防堵件91包含固接于过滤舱73内壁朝向出口端一侧的凸环911，凸环911内壁上固接有支架912，支架912上转动连接有桨叶913，可以理解的是，当负压舱72方向提供吸力的时候，在吸力(气流)的作用下，将使得桨叶913发生转动。Specifically, the anti-blocking member 91 includes a convex ring 911 fixed on the inner wall of the filter cabin 73 toward the outlet end. A bracket 912 is fixed on the inner wall of the convex ring 911, and a paddle 913 is rotatably connected to the bracket 912. It can be understood that , when the negative pressure cabin 72 provides suction, the blades 913 will rotate under the action of the suction (air flow).
其中，过滤件92包含和过滤舱73内壁滑动配合的滤网921，滤网921上固接的连杆922，连杆922另一端固接的挡片923。The filter element 92 includes a filter screen 921 that is slidably matched with the inner wall of the filter cabin 73 , a connecting rod 922 fixed on the filter screen 921 , and a baffle 923 fixed on the other end of the connecting rod 922 .

进一步的，挡片923远离滤网921的一端抵接有第二弹性件924，第二弹性件924可使得滤网921和凸环911之间形成抵接，增强桨叶913转动时对滤网921上提供的清除效果。Furthermore, one end of the baffle 923 away from the filter 921 is in contact with a second elastic member 924. The second elastic member 924 can cause the filter 921 to contact the convex ring 911, thereby enhancing the impact of the blade 913 on the filter when rotating. The clearing effect provided on 921.
进一步的，过滤舱73的入口端位于滤网921和挡片923之间，且过滤舱73靠近挡片923的一端呈可拆卸的密封式设置，便于对过滤舱73内部进行拆卸清洗。Furthermore, the inlet end of the filter cabin 73 is located between the filter screen 921 and the baffle 923, and the end of the filter cabin 73 close to the baffle 923 is detachably sealed to facilitate disassembly and cleaning of the interior of the filter cabin 73.
由此，在具体使用的时候，随着吸力输送到过滤舱73内的液体以及其中混合的异物，将受到滤网921的过滤，其中异物将被阻隔在滤网921和挡片923之间，液体继续向干式过滤器6内输送，在第二弹性件924的作用下，使得滤网921和凸环911之间形成抵接，而在负压吸力的作用下，使得桨叶913发生转动，转动的桨叶913将对滤网921上黏连的异物进行一定程度的清理，避免异物将滤网921造成堵塞，影响液体的输送，而过滤舱73靠近挡片923的一端呈可拆卸的密封式设置，使得过滤舱73内的滤网921可以取出，进行清理消毒。Therefore, during specific use, the liquid transported to the filter cabin 73 with the suction force and the foreign matter mixed therein will be filtered by the filter screen 921, and the foreign matter will be blocked between the filter screen 921 and the baffle 923. The liquid continues to be transported into the dry filter 6. Under the action of the second elastic member 924, the filter screen 921 and the convex ring 911 are in contact, and under the action of negative pressure suction, the paddle 913 is rotated. , the rotating blades 913 will clean the foreign matter adhering to the filter screen 921 to a certain extent to prevent the foreign matter from clogging the filter screen 921 and affecting the transportation of the liquid. The end of the filter cabin 73 close to the baffle 923 is detachable. The sealed arrangement allows the filter screen 921 in the filter cabin 73 to be taken out for cleaning and disinfection.
在相关技术中，该一种带有干式水气分离装置的医用牙椅，在使用过程中，难免会有较细小的异物穿过滤网921进入负压舱72内，而进入负压舱72内的异物在二次负压的时候可能会被吸附向挡块81远离单向阀721的一侧，对导向杆82造成黏连，影响密封块83和导向杆82之间的正常滑动，同时也会对第一弹性件846造成黏连，影响第一弹性件846的正常弹性伸缩，故而，对二次负压提供的吸力大小会造成一定的影响。In the related art, during use of this medical dental chair with a dry water vapor separation device, it is inevitable that smaller foreign matter will pass through the filter 921 and enter the negative pressure chamber 72, and then enter the negative pressure chamber 72. Foreign matter inside may be adsorbed to the side of the stopper 81 away from the one-way valve 721 during the secondary negative pressure, causing adhesion to the guide rod 82 and affecting the normal sliding between the sealing block 83 and the guide rod 82. At the same time, It will also cause adhesion to the first elastic member 846 and affect the normal elastic expansion and contraction of the first elastic member 846. Therefore, it will have a certain impact on the suction force provided by the secondary negative pressure.
根据本申请的一些实施例，如图4和图5所示，负压舱72的内壁上圆周均匀设置有凹槽724，凹槽724和凸缘811滑动配合，对挡块81进行限位，并使得挡块81在负压舱72内可滑动插接，其中相邻凸缘811之间的凹陷处和负压舱72的内壁不抵触，便于挡块81和密封块83之间空间内的液体回流向单向阀721方向，凹槽724延伸至负压舱72远离强弱吸管61一端的端面，便于挡块81从负压舱72内拆卸。According to some embodiments of the present application, as shown in Figures 4 and 5, the inner wall of the negative pressure cabin 72 is evenly provided with grooves 724 around the circumference. The grooves 724 and the flange 811 are in sliding cooperation to limit the stopper 81. And the stopper 81 can be slidably inserted in the negative pressure cabin 72, and the depression between the adjacent flanges 811 does not conflict with the inner wall of the negative pressure cabin 72, which facilitates the space between the stopper 81 and the sealing block 83. The liquid flows back toward the one-way valve 721 , and the groove 724 extends to the end surface of the negative pressure chamber 72 away from the strong and weak suction pipe 61 , making it easier for the stopper 81 to be removed from the negative pressure chamber 72 .
进一步的，导向杆82上套接有第三弹性件85，第三弹性件85位于挡块81和密封块83之间，对密封块83提供一定的复位弹力，促进密封块83复位。Further, a third elastic member 85 is sleeved on the guide rod 82. The third elastic member 85 is located between the stopper 81 and the sealing block 83, and provides a certain reset elastic force to the sealing block 83 to promote the reset of the sealing block 83.
由此，在具体使用的时候，当密封块83从挡块81方向进行复位的时候，通过第三弹性件85提供的弹力，可加强密封块83的复位能力，同时提升密封块83的复位速度，即提升二次负压对过滤舱73方向提供的吸力大小(可以理解的是，当密封块83缓慢复位的时候，过滤舱73进口端所产生的吸力并没有快速复位时所产生的吸力大)，且减弱了进入负压舱72内的异物对导向杆82造成黏连，影响密封块83和导向杆82之间的正常滑动，以及减弱了异物对第一弹性件846造成黏连，影响第一弹性件846的正常弹性伸缩的能力，同时，挡块81在负压舱72内和凹槽724的滑动配合，使得挡块81可拆卸，便于对负压舱72、挡块81、导向杆82、密封块83等相关配件进行清理消毒，进一步减少残留异物在管道内产生病菌，增加交叉感染的风险。Therefore, during specific use, when the sealing block 83 is reset from the direction of the stopper 81 , the elastic force provided by the third elastic member 85 can enhance the resetting ability of the sealing block 83 and at the same time increase the resetting speed of the sealing block 83 . , that is, the amount of suction provided by increasing the secondary negative pressure in the direction of the filter cabin 73 (it can be understood that when the sealing block 83 is slowly reset, the suction force generated by the inlet end of the filter cabin 73 is not as large as when the seal block 83 is reset quickly. ; The normal elastic expansion and contraction ability of the first elastic member 846 and the sliding cooperation of the stopper 81 with the groove 724 in the negative pressure cabin 72 make the stopper 81 detachable, which facilitates the adjustment of the negative pressure cabin 72, the stopper 81, and the guide. The rod 82, sealing block 83 and other related accessories should be cleaned and disinfected to further reduce the residual foreign matter that generates germs in the pipeline and increase the risk of cross-infection.
需要说明的是，牙椅1、电源开关2、漱口池4、微动开关41、强弱吸手机5、干式过滤器6、单向阀721、第一弹性件846、第三弹性件85、桨叶913和第二弹性件924具体的型号规格需根据该装置的实际规格等进行选型确定，具体选型计算方法采用本领域现有技术，故不再详细赘述。It should be noted that dental chair 1, power switch 2, mouthwash basin 4, micro switch 41, strong and weak suction handpiece 5, dry filter 6, one-way valve 721, first elastic member 846, third elastic member 85.
