技术领域Technical Field
本实用新型涉及医疗装置技术领域，更具体地，涉及一种用于重症患者的双面负压牙刷。The utility model relates to the technical field of medical devices, and more specifically, to a double-sided negative pressure toothbrush for critically ill patients.
背景技术Background Art
现有技术中，由于重症监护室(Intensive Care Unit，ICU)患者病情严重，往往需要长时间的卧床休息，导致口腔卫生状况不佳，容易引发一系列口腔感染和并发症状，因此口腔护理是ICU中非常重要的一项护理工作。In the prior art, since patients in the Intensive Care Unit (ICU) are in serious condition, they often need to stay in bed for a long time, which leads to poor oral hygiene and easily causes a series of oral infections and complications. Therefore, oral care is a very important nursing work in the ICU.
目前在ICU中对于昏迷或镇静患者较为常用的是“冲洗式口护吸痰管”，俗称“负压吸引牙刷”，可实现口内冲洗、吸痰的操作。冲洗式负压吸引牙刷在口腔护理中应用冲洗与擦拭结合的方法，使口腔护理液在口腔内流动，加之冲击、擦拭，使寄居附着于口腔黏膜、齿缝中的微生物脱落，并利用连接的负压随着冲洗液被吸出，达到清洁口腔的作用。整个操作简单方便，可冲、可吸、可控，还可以减少患者呛咳、误吸风险的发生。At present, the "rinsing mouth protection suction tube", commonly known as "negative pressure suction toothbrush", is commonly used in ICU for comatose or sedated patients. It can realize the operation of oral flushing and suction. The flushing negative pressure suction toothbrush uses a combination of flushing and wiping in oral care, so that the oral care liquid flows in the mouth, and the impact and wiping make the microorganisms living and attached to the oral mucosa and the teeth fall off, and the negative pressure is used to suck them out with the flushing liquid to achieve the effect of cleaning the mouth. The whole operation is simple and convenient, and it can be flushed, sucked, and controlled. It can also reduce the risk of choking and aspiration of patients.
目前市面上应用较为普遍的负压吸引牙刷分为两种材质，一种为“海绵头”式负压吸引牙刷。由于重症患者多数留置胃管、气管套管等，或伴有吞咽障碍等情况，口咽部分泌物通常较多。在完成一次口腔护理后，很难对海绵头进行清洁。由于海绵本身缺乏硬度，对于患者牙齿上的一些污垢(牙菌斑、软垢和牙结石)，难以做到深层清洁。At present, the more commonly used negative pressure suction toothbrushes on the market are divided into two materials. One is the "sponge head" type negative pressure suction toothbrush. Since most critically ill patients have indwelling gastric tubes, tracheal tubes, etc., or have swallowing disorders, etc., there are usually more secretions in the oropharynx. After completing an oral care, it is difficult to clean the sponge head. Due to the lack of hardness of the sponge itself, it is difficult to achieve deep cleaning of some dirt on the patient's teeth (plaque, soft scale and tartar).
另外一种为“硬质”材质的带毛牙刷头，牙刷头为硬质塑料并附带医用硅胶。尽管硬质带毛牙刷头具备了更深层的清洁功能，能够对患者的牙齿咬合面、牙外侧面、齿缝等起到清洁作用。但对于患者舌根部、舌下面及侧颊等部位，牙刷头因为质地偏硬会容易损伤黏膜。并且硬质牙刷头与患者舌面、侧颊部分也不能很好的贴合，从而影响口腔护理效果。若用牙刷头毛面清洁完齿缝等，再单独用棉球擦拭，也会增加医护人员的工作量。The other type is a "hard" toothbrush head with bristles. The toothbrush head is made of hard plastic and comes with medical silicone. Although the hard bristled toothbrush head has a deeper cleaning function and can clean the patient's occlusal surface, outer surface of the teeth, and interdental spaces, etc. However, for the root of the patient's tongue, under the tongue, and side cheeks, the toothbrush head can easily damage the mucosa due to its hard texture. In addition, the hard toothbrush head cannot fit well with the patient's tongue and side cheeks, thus affecting the oral care effect. If the bristle side of the toothbrush head is used to clean the interdental spaces, etc., and then wiped with a cotton ball alone, it will also increase the workload of medical staff.
“硬质牙刷头”式负压吸引牙刷在牙刷柄内设置开放式小孔，通过连接负压装置，同时用手指封住开放式小孔，在牙刷管腔内形成密闭负压。在操作过程中，医护人员不仅要随时调整牙刷角度，还需要控制口腔护理液在口腔中能边冲洗边吸引。过程中若由于各种原因导致人为封住开放式小孔不到位，导致吸引的负压压力不理想，冲洗液极易造成患者呛咳、误吸，从而影响患者的治疗效果。此外，“硬质牙刷头”式负压吸引牙刷的冲洗和吸引至少部分路段共用一个管腔，容易导致冲洗液和吸引的废液混在一起，难以控制，不方便同步进行冲洗和负压吸引。一般操作是边冲洗边吸引，冲洗和吸引交叉进行，一定程度上会同时影响冲洗和吸引效果。The "hard toothbrush head" type negative pressure suction toothbrush has an open hole in the toothbrush handle. By connecting a negative pressure device and sealing the open hole with fingers, a closed negative pressure is formed in the toothbrush lumen. During the operation, medical staff must not only adjust the angle of the toothbrush at any time, but also control the oral care solution to be able to rinse and suck in the mouth. If the open hole is not sealed properly due to various reasons during the process, resulting in unsatisfactory negative pressure for suction, the flushing liquid can easily cause the patient to choke and aspirate, thereby affecting the patient's treatment effect. In addition, the flushing and suction of the "hard toothbrush head" type negative pressure suction toothbrush share a lumen at least in part, which can easily cause the flushing liquid and the waste liquid of the suction to mix together, making it difficult to control and inconvenient to perform flushing and negative pressure suction simultaneously. The general operation is to flush and suck at the same time, and flushing and suction are carried out alternately, which will affect the flushing and suction effects to a certain extent.
CN215271107U公开了一种适用于重症患者的牙刷，包括牙刷柄和牙刷头，所述牙刷头固定于牙刷柄顶部，所述牙刷头包括进液腔与排液腔，所述进液腔与排液腔固定连接，所述进液腔与排液腔上均设置有孔洞，所述进液腔上可拆卸连接有医用海绵，所述牙刷柄内设置有进液管与排液管，所述进液管与进液腔贯通，所述排液管与排液腔贯通，本实用新型具有以下优点和效果：U型锯齿形医用海绵缩短清洁时间的同时提升清洁效果，设置进液管和排液管保证良好的卫生状况。CN215271107U discloses a toothbrush suitable for critically ill patients, comprising a toothbrush handle and a toothbrush head, wherein the toothbrush head is fixed to the top of the toothbrush handle, the toothbrush head comprises a liquid inlet chamber and a liquid discharge chamber, the liquid inlet chamber and the liquid discharge chamber are fixedly connected, holes are arranged on the liquid inlet chamber and the liquid discharge chamber, a medical sponge is detachably connected to the liquid inlet chamber, a liquid inlet pipe and a liquid discharge pipe are arranged in the toothbrush handle, the liquid inlet pipe is communicated with the liquid inlet chamber, and the liquid discharge pipe is communicated with the liquid discharge chamber. The utility model has the following advantages and effects: the U-shaped serrated medical sponge shortens the cleaning time and improves the cleaning effect at the same time, and the liquid inlet pipe and the liquid discharge pipe are arranged to ensure good sanitary conditions.
该牙刷可拆卸连接有医用海绵，为“海绵头”式负压吸引牙刷。由于海绵本身缺乏硬度，对于患者牙齿上的一些污垢(牙菌斑、软垢和牙结石)，无法像硬质带毛牙刷头具备了更深层的清洁功能，不能对患者的牙齿咬合面、牙外侧面、齿缝等起到清洁作用。此外，该牙刷需要在清洁完毕后，再连接负压装置进行排液，不能边冲洗边排液，容易导致患者口腔中废液溢出口腔，弄脏全身并且不便于清洁。The toothbrush is detachably connected to a medical sponge and is a "sponge head" type negative pressure suction toothbrush. Since the sponge itself lacks hardness, it cannot have a deeper cleaning function for some dirt (plaque, soft scale and tartar) on the patient's teeth like a hard bristled toothbrush head, and cannot clean the patient's tooth occlusal surface, outer surface of the teeth, and interdental spaces. In addition, the toothbrush needs to be connected to a negative pressure device for drainage after cleaning, and cannot be rinsed and drained at the same time, which can easily cause the waste liquid in the patient's mouth to overflow from the mouth, dirtying the whole body and making it inconvenient to clean.

本实用新型在使用时，冲洗接口连接冲洗装置，比如输液器，能够输入用于清洁口腔的冲洗液对患者口腔进行清洗。冲洗液由冲洗接口输入，经过冲洗腔，最后由海绵牙刷头渗出进入患者口腔。负压接口连接负压装置，用于吸引患者口腔内的废液。废液由硬质牙刷头的吸引孔进入，经过吸引腔，最后由负压接口输出。When the utility model is in use, the flushing interface is connected to a flushing device, such as an infusion device, and a flushing liquid for cleaning the oral cavity can be input to clean the patient's oral cavity. The flushing liquid is input through the flushing interface, passes through the flushing cavity, and finally seeps out from the sponge toothbrush head into the patient's oral cavity. The negative pressure interface is connected to a negative pressure device, which is used to suck the waste liquid in the patient's oral cavity. The waste liquid enters through the suction hole of the hard toothbrush head, passes through the suction cavity, and is finally output from the negative pressure interface.
本实用新型的牙刷头包括硬质牙刷头和海绵牙刷头，其中硬质牙刷头具备深层的清洁功能，能够对患者的牙齿咬合面、牙外侧面、齿缝等起到清洁作用。海绵牙刷头能够用于清洁患者舌根部、舌下面及侧颊等部位，不会因为质地偏硬而容易损伤黏膜，并且海绵牙刷头与患者舌面、侧颊部分能够很好的贴合，具有很好的口腔护理效果，无需用棉球擦拭，节省医护人员的工作量。The toothbrush head of the utility model includes a hard toothbrush head and a sponge toothbrush head. The hard toothbrush head has a deep cleaning function and can clean the occlusal surface, outer surface of the teeth, and interdental spaces of the patient's teeth. The sponge toothbrush head can be used to clean the patient's tongue root, under the tongue, and cheeks. It will not easily damage the mucosa due to its hard texture. The sponge toothbrush head can fit well with the patient's tongue surface and cheeks, and has a good oral care effect. There is no need to wipe with a cotton ball, which saves the workload of medical staff.
牙刷柄的内部设有冲洗腔和吸引腔，冲洗腔和吸引腔彼此间隔，因此可以避免冲洗和吸引共用一个管腔，避免冲洗液和吸引的废液混在一起而难以控制，方便同步进行冲洗和负压吸引，互不影响。由于很难对海绵牙刷头进行清洁，将海绵牙刷头与冲洗腔的一端可拆卸固定，方便在完成一次口腔护理后，能够对海绵牙刷头进行更换。海绵牙刷头可以做一次性使用，操作简单方便，使用安全卫生。The inside of the toothbrush handle is provided with a flushing cavity and a suction cavity, and the flushing cavity and the suction cavity are separated from each other, so that flushing and suction can avoid sharing the same lumen, and flushing liquid and suction waste liquid can avoid mixing and being difficult to control, so that flushing and negative pressure suction can be performed simultaneously without affecting each other. Since it is difficult to clean the sponge toothbrush head, the sponge toothbrush head is detachably fixed to one end of the flushing cavity, so that the sponge toothbrush head can be replaced after completing an oral care. The sponge toothbrush head can be used once, which is simple and convenient to operate, safe and hygienic to use.
此外，牙刷柄的外部设有负压孔和活动块，所述负压孔与吸引腔连通，所述活动块活动打开或封闭负压孔。使用时，医护人员可以灵活控制活动块打开或封闭负压孔，从而控制吸引腔内是否形成密闭负压。医护人员在操作过程中不需要手动封住负压孔，可以根据需要灵活控制负压吸引。机械结构控制相比用手指封住更为稳定可靠，避免导致吸引的负压压力不理想，进而避免冲洗液造成患者呛咳、误吸而影响患者的治疗效果，使用安全可靠。In addition, a negative pressure hole and a movable block are provided on the outside of the toothbrush handle, and the negative pressure hole is connected to the suction chamber, and the movable block is movable to open or close the negative pressure hole. During use, medical staff can flexibly control the movable block to open or close the negative pressure hole, thereby controlling whether a closed negative pressure is formed in the suction chamber. Medical staff do not need to manually seal the negative pressure hole during operation, and can flexibly control the negative pressure suction as needed. Mechanical structure control is more stable and reliable than sealing with fingers, avoiding unsatisfactory negative pressure of suction, thereby avoiding the flushing fluid causing the patient to choke and aspirate, thereby affecting the patient's treatment effect, and is safe and reliable to use.
在一个优选实施方式中，所述牙刷柄的外部设有滑动座，所述滑动座设有滑槽，所述滑槽与负压孔连通，所述活动块与滑槽滑动固定并能够相对滑槽滑动。利用活动块与滑槽的滑动来打开或封闭负压孔，原理类似于美工刀，可以灵活控制活动块。当然，在其他实施方式中，也可以采用转动或者弹性复位等活动方式控制活动块打开或封闭负压孔。In a preferred embodiment, a sliding seat is provided on the outside of the toothbrush handle, and the sliding seat is provided with a slide groove, and the slide groove is connected to the negative pressure hole, and the movable block is slidably fixed to the slide groove and can slide relative to the slide groove. The negative pressure hole is opened or closed by sliding the movable block and the slide groove, and the principle is similar to that of a utility knife, and the movable block can be flexibly controlled. Of course, in other embodiments, the movable block can also be controlled to open or close the negative pressure hole by means of rotation or elastic reset.
更优选地，所述活动块背向滑槽的一面设有防滑纹。防滑纹可以增加活动块背面的摩擦力，方便医护人员手动控制，避免手滑不好操作。More preferably, the movable block is provided with anti-skid patterns on one side facing away from the slide slot, which can increase the friction force on the back of the movable block, facilitate manual control by medical staff, and avoid slipping and difficult operation.
在一个优选实施方式中，所述冲洗腔的一端设有冲洗管，所述冲洗管突出于冲洗腔，所述海绵牙刷头设有冲洗管槽，所述冲洗管相对冲洗管槽能够拆卸固定。海绵本身可以收缩膨胀，将冲洗管插入冲洗管槽即可将海绵牙刷头固定，固定后冲洗管四周的海绵会包紧冲洗管。海绵牙刷头吸水后会进一步与冲洗管紧密贴合。完成口腔护理后，即可将冲洗管从冲洗管槽中用力拔出，从而将海绵牙刷头拆卸。等下次使用时再更换新的海绵牙刷头，装拆方便。In a preferred embodiment, a flushing tube is provided at one end of the flushing cavity, the flushing tube protrudes from the flushing cavity, the sponge toothbrush head is provided with a flushing tube groove, and the flushing tube can be detachably fixed relative to the flushing tube groove. The sponge itself can shrink and expand, and the sponge toothbrush head can be fixed by inserting the flushing tube into the flushing tube groove. After fixation, the sponge around the flushing tube will wrap the flushing tube tightly. After absorbing water, the sponge toothbrush head will further fit tightly with the flushing tube. After completing oral care, the flushing tube can be pulled out of the flushing tube groove with force, thereby disassembling the sponge toothbrush head. Replace the sponge toothbrush head with a new one when it is used next time, which is convenient for assembly and disassembly.
更优选地，所述冲洗管远离冲洗腔的一端设有定位块，所述冲洗管槽包括定位槽和卡位槽，所述定位槽设于冲洗管槽远离冲洗腔的一端，所述定位槽的宽度与定位块的宽度相同并大于卡位槽的宽度。海绵本身可以收缩膨胀，由于定位块的宽度大于卡位槽的宽度，将冲洗管插入冲洗管槽时，冲洗管最前端的定位块会挤压卡位槽，卡位槽受到挤压后会向两侧收缩使得宽度变宽。定位块继续向前推进，直到卡入定位槽。定位块卡入定位槽后，卡位槽没有受到定位块的挤压就会向中间膨胀而恢复宽度，从而在定位块后方卡住定位块，这样定位块就不容易退出冲洗管槽，使得整个海绵牙刷头能够进一步稳固固定。完成口腔护理后，需要将冲洗管从冲洗管槽中用力拔出，其中定位块脱离定位槽后进入卡位槽，卡位槽受到挤压后会向两侧收缩使得宽度变宽。定位块继续退出，直到完全退出冲洗管槽，从而将海绵牙刷头拆卸。More preferably, a positioning block is provided at one end of the flushing tube away from the flushing cavity, and the flushing tube groove includes a positioning groove and a clamping groove. The positioning groove is provided at one end of the flushing tube groove away from the flushing cavity, and the width of the positioning groove is the same as the width of the positioning block and is greater than the width of the clamping groove. The sponge itself can shrink and expand. Since the width of the positioning block is greater than the width of the clamping groove, when the flushing tube is inserted into the flushing tube groove, the positioning block at the front end of the flushing tube will squeeze the clamping groove, and the clamping groove will shrink to both sides after being squeezed to make the width wider. The positioning block continues to move forward until it is clamped into the positioning groove. After the positioning block is clamped into the positioning groove, the clamping groove will expand toward the middle and restore the width without being squeezed by the positioning block, so that the positioning block is clamped behind the positioning block, so that the positioning block is not easy to exit the flushing tube groove, so that the entire sponge toothbrush head can be further firmly fixed. After completing oral care, the flushing tube needs to be pulled out of the flushing tube groove with force, wherein the positioning block enters the clamping groove after being separated from the positioning groove, and the clamping groove will shrink to both sides after being squeezed to make the width wider. The positioning block continues to be withdrawn until it is completely withdrawn from the flushing tube groove, thereby removing the sponge toothbrush head.
更优选地，所述冲洗管靠近冲洗腔的一端设有固定块，所述冲洗管槽还包括固定槽，所述固定槽设于冲洗管槽靠近冲洗腔的一端，所述固定槽的宽度与固定块的宽度相同并大于卡位槽的宽度。增加固定块与固定槽的配合，方便冲洗管与冲洗管槽之间的相对固定，也进一步提高固定后的稳固性。More preferably, a fixing block is provided at one end of the flushing tube close to the flushing cavity, and the flushing tube slot further comprises a fixing slot, which is provided at one end of the flushing tube slot close to the flushing cavity, and the width of the fixing slot is the same as the width of the fixing block and is greater than the width of the positioning slot. Increasing the coordination between the fixing block and the fixing slot facilitates the relative fixation between the flushing tube and the flushing tube slot, and further improves the stability after fixation.
更优选地，所述固定槽的宽度与定位槽的宽度相同。固定槽的宽度与定位槽的宽度相同，固定块与定位块的宽度也相同，既方便生产制造，也方便装拆固定，还能保持稳固。More preferably, the width of the fixing groove is the same as the width of the positioning groove. The width of the fixing groove is the same as the width of the positioning groove, and the width of the fixing block is the same as the positioning block, which is convenient for production and manufacturing, and is also convenient for assembly and disassembly, and can also maintain stability.
更优选地，所述定位块远离冲洗腔的一端设有第一倾斜面。定位块远离冲洗腔的一端设有第一倾斜面，使得定位块在前进方向形成宽度较窄的尖头，方便卡入卡位槽，进而方便安装固定。More preferably, the end of the positioning block away from the flushing cavity is provided with a first inclined surface. The end of the positioning block away from the flushing cavity is provided with a first inclined surface, so that the positioning block forms a narrow tip in the forward direction, which is convenient for snapping into the positioning groove, thereby facilitating installation and fixing.
更优选地，所述定位块朝向冲洗腔的一端设有第二倾斜面。定位块朝向冲洗腔的一端设有第二倾斜面，使得定位块在后退方向形成宽度较窄的尖头，方便退出卡位槽，进而方便将冲洗管从冲洗管槽中用力拔出。More preferably, the end of the positioning block facing the flushing cavity is provided with a second inclined surface, so that the positioning block forms a narrow tip in the backward direction, which is convenient for exiting the positioning groove, and then convenient for pulling the flushing tube out of the flushing tube groove.
在一个优选实施方式中，所述冲洗管的周面设有冲洗孔阵列。冲洗孔阵列便于冲洗液快速且全面地湿润海绵牙刷头，进而便于清洁患者口腔，提高工作效率。In a preferred embodiment, the circumferential surface of the flushing tube is provided with a flushing hole array, which facilitates the flushing liquid to quickly and comprehensively wet the sponge toothbrush head, thereby facilitating cleaning of the patient's oral cavity and improving work efficiency.

具体实施方式DETAILED DESCRIPTION
下面结合附图和具体实施例，对本实用新型做进一步详细说明。The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
如图1至图4所示，本实用新型的一种用于重症患者的双面负压牙刷100，包括牙刷头和牙刷柄，所述牙刷头设于牙刷柄的一端。As shown in FIG. 1 to FIG. 4 , a double-sided negative pressure toothbrush 100 for critically ill patients of the present invention comprises a toothbrush head and a toothbrush handle, wherein the toothbrush head is arranged at one end of the toothbrush handle.
所述牙刷头包括硬质牙刷头101和海绵牙刷头102。所述硬质牙刷头101与牙刷柄固定为一体，所述硬质牙刷头101的一面设有牙刷毛103和吸引孔104，所述海绵牙刷头102设于硬质牙刷头101的另一面。The toothbrush head comprises a hard toothbrush head 101 and a sponge toothbrush head 102. The hard toothbrush head 101 is fixed to a toothbrush handle as a whole, one side of the hard toothbrush head 101 is provided with toothbrush bristles 103 and suction holes 104, and the sponge toothbrush head 102 is provided on the other side of the hard toothbrush head 101.
硬质牙刷头101具备深层的清洁功能，能够对患者的牙齿咬合面、牙外侧面、齿缝等起到清洁作用。海绵牙刷头102能够用于清洁患者舌根部、舌下面及侧颊等部位，不会因为质地偏硬而容易损伤黏膜，并且海绵牙刷头102与患者舌面、侧颊部分能够很好的贴合，具有很好的口腔护理效果，无需用棉球擦拭，节省医护人员的工作量。The hard toothbrush head 101 has a deep cleaning function and can clean the patient's occlusal surface, outer surface of the teeth, and interdental spaces. The sponge toothbrush head 102 can be used to clean the patient's tongue root, under the tongue, and cheeks. It will not easily damage the mucosa due to its hard texture. The sponge toothbrush head 102 can fit well with the patient's tongue and cheeks, and has a good oral care effect. There is no need to wipe with a cotton ball, which saves the workload of medical staff.
所述牙刷柄的内部设有冲洗腔105和吸引腔106，所述冲洗腔105和吸引腔106彼此间隔。因此可以避免冲洗和吸引共用一个管腔，避免冲洗液和吸引的废液混在一起而难以控制，方便同步进行冲洗和负压吸引，互不影响。牙刷柄优选采用浅色透明或者半透明材质制成，这样可以看见冲洗腔105和吸引腔106中液体的颜色、流量以及性状等，方便医护人员调节控制。The inside of the toothbrush handle is provided with a flushing cavity 105 and a suction cavity 106, and the flushing cavity 105 and the suction cavity 106 are spaced from each other. Therefore, flushing and suction can be prevented from sharing a lumen, and the flushing liquid and the suction waste liquid can be prevented from mixing together and being difficult to control, so that flushing and negative pressure suction can be performed simultaneously without affecting each other. The toothbrush handle is preferably made of a light-colored transparent or translucent material, so that the color, flow rate and properties of the liquid in the flushing cavity 105 and the suction cavity 106 can be seen, which is convenient for medical staff to adjust and control.
所述冲洗腔105的一端与海绵牙刷头102能够拆卸固定。由于很难对海绵牙刷头102进行清洁，将海绵牙刷头102与冲洗腔105的一端可拆卸固定，方便在完成一次口腔护理后，能够对海绵牙刷头102进行更换。海绵牙刷头102可以做一次性使用，操作简单方便，使用安全卫生。海绵牙刷头102生产成本低，可以批量生产作为配件使用。One end of the rinsing cavity 105 can be detachably fixed to the sponge toothbrush head 102. Since it is difficult to clean the sponge toothbrush head 102, the sponge toothbrush head 102 is detachably fixed to one end of the rinsing cavity 105, so that the sponge toothbrush head 102 can be replaced after completing an oral care. The sponge toothbrush head 102 can be used once, is simple and convenient to operate, and is safe and hygienic to use. The sponge toothbrush head 102 has a low production cost and can be mass-produced for use as an accessory.
所述冲洗腔105的另一端设有冲洗接口107。使用时，冲洗接口107连接冲洗装置，比如输液器，能够输入用于清洁口腔的冲洗液对患者口腔进行清洗。冲洗液由冲洗接口107输入，经过冲洗腔105，最后由海绵牙刷头102渗出进入患者口腔。The other end of the flushing cavity 105 is provided with a flushing interface 107. When in use, the flushing interface 107 is connected to a flushing device, such as an infusion device, and can input a flushing liquid for cleaning the oral cavity to clean the patient's oral cavity. The flushing liquid is input through the flushing interface 107, passes through the flushing cavity 105, and finally seeps out from the sponge toothbrush head 102 into the patient's oral cavity.
所述吸引腔106的一端与吸引孔104连通，所述吸引腔106的另一端设有负压接口108。使用时，负压接口108连接负压装置，用于吸引患者口腔内的废液。废液由硬质牙刷头101的吸引孔104进入，经过吸引腔106，最后由负压接口108输出。One end of the suction chamber 106 is connected to the suction hole 104, and the other end of the suction chamber 106 is provided with a negative pressure interface 108. When in use, the negative pressure interface 108 is connected to a negative pressure device to suck the waste liquid in the patient's oral cavity.

所述牙刷柄的外部设有负压孔109和活动块110，所述负压孔109与吸引腔106连通，所述活动块110活动打开或封闭负压孔109。使用时，医护人员可以灵活控制活动块110打开或封闭负压孔109，从而控制吸引腔106内是否形成密闭负压。医护人员在操作过程中不需要手动封住负压孔109，可以根据需要灵活控制负压吸引。机械结构控制相比用手指封住更为稳定可靠，避免导致吸引的负压压力不理想，进而避免冲洗液造成患者呛咳、误吸而影响患者的治疗效果，使用安全可靠。The outside of the toothbrush handle is provided with a negative pressure hole 109 and a movable block 110, the negative pressure hole 109 is connected to the suction chamber 106, and the movable block 110 is movable to open or close the negative pressure hole 109. During use, medical staff can flexibly control the movable block 110 to open or close the negative pressure hole 109, so as to control whether a closed negative pressure is formed in the suction chamber 106. Medical staff do not need to manually seal the negative pressure hole 109 during operation, and can flexibly control the negative pressure suction as needed. Mechanical structure control is more stable and reliable than sealing with fingers, avoiding unsatisfactory negative pressure caused by suction, thereby avoiding the flushing fluid causing the patient to choke and aspirate, thereby affecting the patient's treatment effect, and is safe and reliable to use.
本实施例中，所述牙刷柄的外部设有滑动座111，所述滑动座111设有滑槽112，所述滑槽112与负压孔109连通，所述活动块110与滑槽112滑动固定并能够相对滑槽112滑动。利用活动块110与滑槽112的滑动来打开或封闭负压孔109，原理类似于美工刀，可以灵活控制活动块110。当然，在其他实施例中，也可以采用转动或者弹性复位等活动方式控制活动块打开或封闭负压孔。In this embodiment, a sliding seat 111 is provided on the outside of the toothbrush handle, and the sliding seat 111 is provided with a slide groove 112, and the slide groove 112 is connected to the negative pressure hole 109, and the movable block 110 is slidably fixed with the slide groove 112 and can slide relative to the slide groove 112.

Of course, in other embodiments, the movable block can also be controlled to open or close the negative pressure hole by means of rotation or elastic reset.
本实施例中，所述活动块110背向滑槽112的一面设有防滑纹113。防滑纹113可以增加活动块110背面的摩擦力，方便医护人员手动控制，避免手滑不好操作。In this embodiment, the movable block 110 is provided with anti-skid patterns 113 on one side facing away from the slide slot 112. The anti-skid patterns 113 can increase the friction force on the back of the movable block 110, facilitate manual control by medical staff, and avoid slipping and difficult operation.
如图4至图8所示，本实施例中，所述冲洗腔105的一端设有冲洗管114，所述冲洗管114突出于冲洗腔105，所述海绵牙刷头102设有冲洗管槽115，所述冲洗管114相对冲洗管槽115能够拆卸固定。海绵本身可以收缩膨胀，将冲洗管114插入冲洗管槽115即可将海绵牙刷头102固定，固定后冲洗管114四周的海绵会包紧冲洗管114。海绵牙刷头102吸水后会进一步与冲洗管114紧密贴合。完成口腔护理后，即可将冲洗管114从冲洗管槽115中用力拔出，从而将海绵牙刷头102拆卸。等下次使用时再更换新的海绵牙刷头102，装拆方便。As shown in FIGS. 4 to 8 , in this embodiment, a flushing tube 114 is provided at one end of the flushing cavity 105, and the flushing tube 114 protrudes from the flushing cavity 105. The sponge toothbrush head 102 is provided with a flushing tube groove 115, and the flushing tube 114 can be detached and fixed relative to the flushing tube groove 115. The sponge itself can shrink and expand, and the sponge toothbrush head 102 can be fixed by inserting the flushing tube 114 into the flushing tube groove 115. After fixing, the sponge around the flushing tube 114 will wrap the flushing tube 114 tightly. After absorbing water, the sponge toothbrush head 102 will further fit closely with the flushing tube 114. After completing oral care, the flushing tube 114 can be pulled out from the flushing tube groove 115 by force, so as to disassemble the sponge toothbrush head 102. When it is used next time, a new sponge toothbrush head 102 can be replaced, which is convenient for assembly and disassembly.
本实施例中，所述冲洗管114的周面设有冲洗孔阵列116。冲洗孔阵列116便于冲洗液快速且全面地湿润海绵牙刷头102，进而便于清洁患者口腔，提高工作效率。In this embodiment, a flushing hole array 116 is provided on the circumferential surface of the flushing tube 114. The flushing hole array 116 facilitates the flushing liquid to quickly and comprehensively wet the sponge toothbrush head 102, thereby facilitating cleaning of the patient's oral cavity and improving work efficiency.
本实施例中，所述冲洗管114远离冲洗腔105的一端设有定位块117，所述冲洗管槽115包括定位槽118和卡位槽119，所述定位槽118设于冲洗管槽115远离冲洗腔105的一端，所述定位槽118的宽度与定位块117的宽度相同并大于卡位槽119的宽度。海绵本身可以收缩膨胀，由于定位块117的宽度大于卡位槽119的宽度，将冲洗管114插入冲洗管槽115时，冲洗管114最前端的定位块117会挤压卡位槽119，卡位槽119受到挤压后会向两侧收缩使得宽度变宽。定位块117继续向前推进，直到卡入定位槽118。定位块117卡入定位槽118后，卡位槽119没有受到定位块117的挤压就会向中间膨胀而恢复宽度，从而在定位块117后方卡住定位块117，这样定位块117就不容易退出冲洗管槽115，使得整个海绵牙刷头102能够进一步稳固固定。完成口腔护理后，需要将冲洗管114从冲洗管槽115中用力拔出，其中定位块117脱离定位槽118后进入卡位槽119，卡位槽119受到挤压后会向两侧收缩使得宽度变宽。定位块117继续退出，直到完全退出冲洗管槽115，从而将海绵牙刷头102拆卸。In this embodiment, a positioning block 117 is provided at one end of the flushing tube 114 away from the flushing cavity 105, and the flushing tube groove 115 includes a positioning groove 118 and a clamping groove 119. The positioning groove 118 is provided at one end of the flushing tube groove 115 away from the flushing cavity 105, and the width of the positioning groove 118 is the same as the width of the positioning block 117 and is greater than the width of the clamping groove 119. The sponge itself can shrink and expand. Since the width of the positioning block 117 is greater than the width of the clamping groove 119, when the flushing tube 114 is inserted into the flushing tube groove 115, the positioning block 117 at the front end of the flushing tube 114 will squeeze the clamping groove 119, and the clamping groove 119 will shrink to both sides after being squeezed, so that the width becomes wider. The positioning block 117 continues to move forward until it is clamped into the positioning groove 118. After the positioning block 117 is inserted into the positioning groove 118, the positioning groove 119 will expand toward the middle and restore its width without being squeezed by the positioning block 117, thereby squeezing the positioning block 117 behind the positioning block 117. In this way, the positioning block 117 is not easy to withdraw from the flushing tube groove 115, so that the entire sponge toothbrush head 102 can be further firmly fixed. After completing oral care, the flushing tube 114 needs to be pulled out from the flushing tube groove 115 with force, wherein the positioning block 117 is separated from the positioning groove 118 and enters the positioning groove 119. After being squeezed, the positioning groove 119 will shrink to both sides to make the width wider. The positioning block 117 continues to withdraw until it completely withdraws from the flushing tube groove 115, thereby disassembling the sponge toothbrush head 102.
本实施例中，所述定位块117远离冲洗腔105的一端设有第一倾斜面120。定位块117远离冲洗腔105的一端设有第一倾斜面120，使得定位块117在前进方向形成宽度较窄的尖头，方便卡入卡位槽119，进而方便安装固定。In this embodiment, the end of the positioning block 117 away from the flushing cavity 105 is provided with a first inclined surface 120. The end of the positioning block 117 away from the flushing cavity 105 is provided with a first inclined surface 120, so that the positioning block 117 forms a narrow tip in the forward direction, which is convenient for snapping into the positioning groove 119, thereby facilitating installation and fixing.
本实施例中，所述定位块117朝向冲洗腔105的一端设有第二倾斜面121。定位块117朝向冲洗腔105的一端设有第二倾斜面121，使得定位块117在后退方向形成宽度较窄的尖头，方便退出卡位槽119，进而方便将冲洗管114从冲洗管槽115中用力拔出。In this embodiment, the end of the positioning block 117 facing the flushing cavity 105 is provided with a second inclined surface 121. The end of the positioning block 117 facing the flushing cavity 105 is provided with a second inclined surface 121, so that the positioning block 117 forms a narrow tip in the backward direction, which is convenient for exiting the positioning groove 119, and further convenient for forcibly pulling out the flushing tube 114 from the flushing tube groove 115.
本实施例中，所述冲洗管114靠近冲洗腔105的一端设有固定块122，所述冲洗管槽115还包括固定槽123，所述固定槽123设于冲洗管槽115靠近冲洗腔105的一端，所述固定槽123的宽度与固定块122的宽度相同并大于卡位槽119的宽度。增加固定块122与固定槽123的配合，方便冲洗管114与冲洗管槽115之间的相对固定，也进一步提高固定后的稳固性。In this embodiment, a fixing block 122 is provided at one end of the flushing tube 114 close to the flushing cavity 105, and the flushing tube groove 115 further includes a fixing groove 123, which is provided at one end of the flushing tube groove 115 close to the flushing cavity 105, and the width of the fixing groove 123 is the same as the width of the fixing block 122 and is greater than the width of the positioning groove 119. Increasing the cooperation between the fixing block 122 and the fixing groove 123 facilitates the relative fixation between the flushing tube 114 and the flushing tube groove 115, and further improves the stability after fixation.
本实施例中，所述固定槽123的宽度与定位槽118的宽度相同。固定槽123的宽度与定位槽118的宽度相同，固定块122与定位块117的宽度也相同，既方便生产制造，也方便装拆固定，还能保持稳固。In this embodiment, the width of the fixing groove 123 is the same as the width of the positioning groove 118. The width of the fixing groove 123 is the same as the width of the positioning groove 118, and the width of the fixing block 122 is the same as the width of the positioning block 117, which is convenient for production and manufacturing, and is also convenient for assembly and disassembly, and can also maintain stability.
