[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3This utility model provides an embodiment of a U-shaped negative pressure toothbrush device for the care of critically ill patients, including a handle 1. A connecting arm 2 is fixedly connected to the front surface of the handle 1. A cavity is provided between the handle 1 and the connecting arm 2, and the cavities are connected. A connecting seat 7 is fixedly connected to the end of the handle 1 away from the connecting arm 2. By providing the connecting seat 7, an external negative pressure device can be connected to generate suction to connect to the cleaning head 5 through the gap between the handle 1 and the connecting arm 2. The cleaning head 5 can absorb secretions and liquids in the patient's mouth through multiple sets of negative pressure holes on its surface. The cleaning head 5 is detachably installed on the end of the connecting arm 2 away from the handle 1 through a connecting component 4. The cleaning head 5 is integrally formed into a U-shape, and inner arc surfaces are provided on both the upper and lower sides, which are aligned with the upper and lower gums of the human mouth. Negative pressure holes are provided on the inner arc surfaces on both the upper and lower sides, and a cavity is provided inside the cleaning head 5. This allows secretions and liquids drawn in through the negative pressure port to enter the cavity of the cleaning head 5 and be drawn out through the cavity of the connecting arm 2 from the connecting seat 7. The inner side wall of the cleaning head 5 is provided with a brush 6, and the inner wall of the connecting arm 2 away from the handle 1 is provided with a vibration motor 8. The vibration motor 8 is existing technology. When the cleaning head 5 is installed on the surface of the connecting arm 2 through the connecting component 4, the vibration motor 8 can make the cleaning head 5 vibrate as a whole, which can save the operation time and effort of medical staff and improve the overall cleanliness. The inner side wall of the connecting arm 2 is provided with an adjustment component 3, and there is a connecting channel between the handle 1, the connecting arm 2 and the cleaning head 5 during installation, so that the secretions drawn in by the negative pressure will enter the cavity of the cleaning head 5 through the negative pressure port of the cleaning head 5 and be absorbed by the negative pressure device connected to the connecting seat 7 along the interior of the connecting arm 2 and the handle 1.
[0034] Reference Figure 4The adjusting component 3 includes an adjusting block 31. The surface of the adjusting block 31 has two sets of through holes of different sizes, one on the left and one on the right, which correspond to the ball groove at the bottom. The surface of the connecting arm 2 has a guide groove. The adjusting block 31 passes through and slides along the inner wall of the guide groove of the connecting arm 2. A square guide block is provided at the top of the adjusting block 31, which fits into the inner side of the connecting arm 2, allowing the adjusting block 31 to move laterally only along the inner wall of the connecting arm 2. The bottom end of the inner wall of the connecting arm 2 is elastically connected to a limiting ball 33 via a return spring 32. One end of the return spring 32 is fixedly connected to the bottom end of the outer wall of the limiting ball 33. The other end of 32 is fixedly connected to the bottom end of the inner wall of the connecting arm 2. The function of the return spring 32 is to automatically reset the position of the spherical surface of the upper end of the limit ball 33 after it is squeezed and moved by the arc surface of the bottom end of the adjusting block 31. The bottom end of the adjusting block 31 is provided with two sets of ball grooves. The outer wall of the top end of the limit ball 33 is in contact with the inner wall of the ball groove at the bottom end of the adjusting block 31. The contact between the two makes the adjusting block 31 not move under the influence of external force, so that the two sets of through holes of different sizes can be fixed at the position of the movement of the inner wall of the connecting arm 2, thereby achieving the adjustment of the negative pressure. The limit ball 33 is slidably connected to the bottom end of the inner wall of the connecting arm 2.
[0035] Reference Figure 2 and Figure 3 The connecting component 4 includes a fixing sleeve 41. A guide block 42 is fixedly connected to the inner side wall of the fixing sleeve 41. The guide block 42 is provided with two sets, upper and lower, and fits into the guide groove on the outer arc surface of the connecting arm 2. A cavity is opened on the outer side of the fixing sleeve 41. A plastic elastic block 43 is provided on the inner wall of the cavity of the fixing sleeve 41. A guide groove is opened at the end of the connecting arm 2. The outer wall of the guide block 42 contacts the inner wall of the guide groove. The outer wall of the fixing sleeve 41 contacts the outer wall of the end of the connecting arm 2. A slot is opened on the side wall of the end of the connecting arm 2. The outer wall of the plastic elastic block 43 engages with the inner wall of the slot. The engagement between the two allows the cleaning head 5 to be fixedly installed at the end of the connecting arm 2, so that the brush 6 on the surface of the cleaning head 5 can be replaced when it is worn. The fixing sleeve 41 is fixedly connected to the outer arc surface of the rear end of the cleaning head 5.
[0036] Working principle: When the patient brushes their teeth, toothpaste is first evenly applied to the brush 6 on the surface of the cleaning head 5. The vibration motor 8 works, and the vibration generated is transmitted to the cleaning head 5, so that the entire cleaning head 5 has a vibration effect. Under the action of vibration, the brush 6 on the inner side wall of the cleaning head 5 can more effectively clean the teeth and the inner wall of the mouth, saving medical staff's operation time and effort and improving the cleanliness.
[0037] Simultaneously, the external negative pressure device connected to the connecting seat 7 generates suction. The suction is transmitted to the cleaning head 5 through the cavity of the handle 1 and the connecting arm 2. The negative pressure holes on the surface of the cleaning head 5 draw secretions and liquids from the patient's mouth into the cavity of the cleaning head 5, and then through the cavity of the connecting arm 2 and the handle 1, and finally extracted from the connecting seat 7 by the negative pressure device, thus removing foreign objects from the mouth. When the negative pressure needs to be adjusted, the adjusting block 31 is pushed to move laterally on the inner wall of the connecting arm 2. When the adjusting block 31 moves, the arc surface at its bottom end squeezes the limiting ball 33, causing the limiting ball 33 to compress the return spring 32 and move downward. When the adjusting block 31 moves to the appropriate position, the limiting ball 33 is re-locked into the ball groove at the bottom end of the adjusting block 31 under the action of the return spring 32, fixing the position of the adjusting block 31. At this time, the through holes of different sizes on the adjusting block 31 are at different positions on the inner wall of the connecting arm 2, changing the cross-sectional area of the negative pressure channel, thereby realizing the adjustment of the negative pressure.
[0038] When installing the cleaning head 5, align the guide block 42 on the fixing sleeve 41 with the guide groove at the end of the connecting arm 2 and insert it so that the outer wall of the fixing sleeve 41 contacts the outer wall at the end of the connecting arm 2. At this time, the plastic elastic clip 43 is inserted into the slot at the end of the connecting arm 2 to fix the position of the cleaning head 5. When the brush 6 on the surface of the cleaning head 5 is worn and needs to be replaced, press the plastic elastic clip 43 to disengage it from the slot, and then pull the fixing sleeve 41 out from the end of the connecting arm 2 to remove the cleaning head 5 for replacement.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
