Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Embodiment 1

[0035] In order to solve the problem that the oral care solution in the existing sealed oral care device may precipitate or stratify after being placed for a long time, medical staff need to manually shake the oral care solution before use to mix it. However, manual shaking is difficult to fully and evenly mix the oral care solution, thus affecting the care effect. Figure 1-Figure 5 The present invention provides a disposable closed liquid storage oral care device for critical pediatrics, comprising a handle 1 and a thin rod body 2 integrally formed at the end of the handle 1, wherein a liquid storage chamber 101 for storing oral care liquid is provided in the handle 1, and a piston 102 is provided in the liquid storage chamber 101; a liquid outlet chamber 201 connected to the liquid storage chamber 101 is provided in the thin rod body 2, and a one-way valve 203 is provided in the liquid outlet chamber 201, the liquid outlet chamber 201 extends to the end of the thin rod body 2, and a plurality of evenly distributed liquid outlet micropores 202 are provided on the inner surface, a sponge 3 is provided at the end of the thin rod body 2, and the sponge 3 completely wraps the liquid outlet micropores 202, the oral care liquid flows into the sponge 3 through the liquid outlet chamber 201, and the oral care liquid is applied through the sponge 3. The handle 1 is also provided with a mixing component 4 and a liquid outlet component 5 which are distributed axially along the liquid storage chamber 101 and are sleeved around the liquid storage chamber 101. The mixing component 4 is used to use compressed gas to stir the oral care liquid before use, and the liquid outlet component 5 is used to use compressed gas to push the oral care liquid out. The compressed gas can be set to compressed air or other medical non-toxic gas.

[0036] The mixing component 4 includes a first annular storage bin 401 for storing compressed gas. A certain amount of compressed gas for disposable use is pre-filled inside the first annular storage bin 401. The design of the annular first annular storage bin 401 surrounding the liquid storage chamber 101 makes full use of the space inside the handle 1, making the structure of the entire oral care device more compact. A plurality of evenly distributed branch pipes 402 are provided on the inner surface of the first annular storage bin 401. The branch pipes 402 spray compressed gas to stir the oral care liquid. A plurality of air inlet holes 103 corresponding to the branch pipes 402 are provided around the liquid storage chamber 101 located at the mixing component 4. The extension line of the air inlet hole 103 is tangent to the edge of the liquid storage chamber 101. The compressed gas enters the liquid storage chamber 101 through the air inlet hole 103. Due to the tangential setting, the care liquid in the liquid storage chamber 101 can be driven to rotate. The end of the branch pipe 402 is closed, and the mixing assembly 4 also includes a cutting unit for cutting off the closed end of the branch pipe 402; the cutting unit includes a cutting frame 403 and an arc-shaped ring body 404 for driving the cutting frame 403 to rotate, and a plurality of cutting bodies are arranged on the cutting frame 403. The arc-shaped ring body 404 is fixed at the end of the cutting frame 403 and is rotatably arranged in the groove on the outer surface of the handle 1. A clamping column 405 is arranged at the end of the arc-shaped ring body 404, and a clamping groove matching the clamping column 405 is arranged in the groove.

[0037] Before using the oral care device, manually rotate the arc ring body 404, the arc ring body 404 rotates along the groove, and drives the cutter frame 403 to rotate, and the cutter frame 403 drives the cutter body therein to rotate, cuts off the closed end of the branch pipe 402, and then reverses the arc ring body 404 to reset the cutter body. At this time, the compressed gas in the first annular storage bin 401 loses its restraint, and rushes into the liquid storage chamber 101 through the branch pipe 402 and the air inlet 103 in the form of high-speed airflow, driving the care liquid to rotate and forming a large number of tiny bubbles in the care liquid, producing a stirring and mixing effect, and achieving uniform mixing of the care liquid. A certain amount of space needs to be left in the liquid storage chamber 101 for the care liquid pre-filled, that is, it does not need to be filled, so that the compressed gas can It smoothly enters the liquid storage chamber 101, and is stirred evenly to form a gas-liquid mixture, which is then pushed out through the liquid outlet component 5, and mixed using the powerful impact of the compressed gas. Compared with traditional mixing methods such as manual shaking, it can achieve uniform mixing of the care liquid in a very short time, greatly improve the use efficiency, meet emergency care needs, avoid precipitation or stratification of the care liquid after long-term storage, ensure that the care liquid remains in a uniform state during use, and make the proportion of the care liquid sprayed each time stable, thereby improving the care effect. After mixing is completed, rotate the arc ring body 404 again to block the air inlet 103 through the cutter body. At this time, the cutter body acts as a baffle to prevent the oral care liquid from flowing out of the air inlet 103.

[0038] The liquid outlet component 5 includes a second annular storage bin 501 for storing compressed gas, and a certain amount of compressed gas for one-time use is pre-filled inside the second annular storage bin 501; a first gas pipe 502 is provided on the second annular storage bin 501, and the end of the first gas pipe 502 extends to the end of the liquid storage chamber 101 away from the thin rod body 2, which is used to push the piston 102 to move to achieve liquid discharge, and a first regulating valve 503 for controlling the gas flow is provided on the first gas pipe 502, and the regulating part of the first regulating valve 503 extends to the outer end surface of the handle 1.

[0039] When in use, open the first regulating valve 503. At this time, the compressed gas in the second annular storage bin 501 is input into the liquid storage chamber 101 through the first air pipe 502, pushing the piston 102 to move. The piston 102 pushes the care liquid into the liquid outlet chamber 201, and finally flows into the sponge 3 from the liquid outlet micropores 202, and is smeared into the oral cavity of the critically ill child through the sponge 3.

[0040] In order to reduce the fear and discomfort of critically ill children during the nursing process, Figure 1 , Figure 7 As shown, the handle 1 is also provided with a soothing component 6 which is sleeved around the liquid storage chamber 101. The soothing component 6 is used to use compressed gas to drive the children's toy to rotate to soothe critically ill children. The soothing component 6 includes a third annular storage bin 601 for storing compressed gas. The third annular storage bin 601 is pre-filled with a certain amount of compressed gas for one-time use. The third annular storage bin 601 is provided with a second gas pipe 602. The second gas pipe 602 is provided with a second regulating valve 603 for controlling the gas flow. The regulating part of the second regulating valve 603 also extends to the outer end surface of the handle 1 for the convenience of use by medical staff. The end of the second gas pipe 602 extends to the end of the handle 1 close to the thin rod body 2 and is fixedly provided with an annular tube 604; the soothing component 6 also includes a plurality of windmill toy units 606 that are evenly distributed and rotatably arranged on the end surface of the handle 1, and the annular tube 604 is provided with a plurality of air outlet pipes 605 for driving the windmill toy units 606 to rotate.

[0041] When in use, open the second regulating valve 603. At this time, the compressed gas in the third annular storage bin 601 is input into the annular tube 604 through the second air supply pipe 602, and finally ejected from the multiple air outlet pipes 605 to drive the windmill toy unit 606 to rotate. The windmill toy unit 606 can be set to colorful colors and have a variety of animal shapes, etc. The windmill toy unit 606 can be used to attract the attention of critically ill children, relieve their tension, and make the oral care process smoother. The rotation speed of the windmill toy unit 606 can be adjusted by the second regulating valve 603. At the same time, the breeze ejected from the air outlet pipe 605 also has a certain soothing effect, reducing the fear and discomfort of critically ill children during the care process.

[0042] Embodiment 2

[0043] On the basis of the first embodiment, in order to make the oral care device disposable and avoid the problem of infection caused by repeated use, as Figure 1 , Figure 6 As shown, the end of the liquid storage cavity 101 near the thin rod body 2 is provided with a self-destruct component 7 for blocking the liquid outlet cavity 201 so that the nursing device cannot discharge liquid normally. After use, the liquid outlet cavity 201 can be automatically blocked by the self-destruct component 7 to avoid infection caused by repeated use.

[0044] The self-destruct component 7 includes two first spring support columns 701 symmetrically fixed on the inner wall of the liquid storage chamber 101, and the ends of the two first spring support columns 701 are fixed with clamping members 702, a blocking block 703 is provided between the two clamping members 702, and a magnetic attraction sheet 704 is provided below the blocking block 703 and is attracted to the blocking block 703 and fixed on the end surface of the liquid storage chamber 101; one end of the clamping member 702 is provided with a lap portion 702b for lap-joining the blocking block 703, and the other end is provided with a wedge portion 702a, and the bottom of the piston 102 is fixedly provided with a conical portion 104 that matches the wedge portion 702a.

[0045] When the piston 102 moves to the lower end of the liquid outlet chamber 201, the conical portion 104 squeezes the wedge portion 702a to drive the clamping member 702 to move, and the blocking block 703 loses its support and falls off, and is attracted to the magnetic sheet 704 to block the liquid outlet chamber 201, so that the care device cannot discharge liquid normally again.

[0046] Embodiment 3

[0047] On the basis of the first and second embodiments, in order to improve the safety of the oral care device, Figure 8-Figure 9 As shown, the outer end inner cavity of the thin rod body 2 is provided with an anti-choking component 8 for automatically sensing the airflow velocity in the oral cavity of the critically ill child to block the liquid outlet microhole 202 to prevent the critically ill child from choking. When the critically ill child chokes during the nursing process, the liquid outlet microhole 202 can be automatically and quickly closed based on the airflow changes in the child's mouth to ensure the safety of the child.

[0048] The anti-choking component 8 includes an inner ring body 801 rotatably arranged in the liquid outlet cavity 201 and a fan unit 805 for driving the inner ring body 801 to rotate, the inner ring body 801 is provided with a plurality of through holes 802 corresponding to the liquid outlet micropores 202, and two symmetrically distributed levers 803 are fixedly arranged at the end of the inner ring body 801; a bearing seat 804 for supporting the rotation of the rotating shaft of the fan unit 805 is fixedly arranged in the inner cavity at the end of the thin rod body 2, two symmetrically distributed second spring support columns 806 are fixedly arranged on the rotating shaft of the fan unit 805, and a lever plate 807 is fixedly arranged at the end of the second spring support column 806.

[0049] During normal care, the airflow in the oral cavity of the critically ill child is stable, and the fan unit 805 rotates slightly or does not rotate. At this time, the paddle 807 and the paddle rod 803 are in a separated state. Once the child chokes, the strong airflow generated will cause the fan unit 805 to rotate rapidly, and the fan unit 805 drives the second spring support column 806 and the paddle 807 to rotate. Under the action of centrifugal force, the paddle 807 overcomes the spring tension and is thrown out. The paddle 807 needs to have a certain weight so that it can be thrown out under the action of centrifugal force. At the same time, it also avoids excessive weight and loss of airflow monitoring effect. It can be made of lightweight metal alloy materials, such as aluminum alloy. Generally speaking, the airflow velocity during normal oral breathing is relatively small, while the airflow velocity will increase significantly during coughing and choking. In order to effectively distinguish between normal and abnormal airflow states, the second spring support The spring coefficient of column 806 should not be too large, otherwise it will be difficult for a weak abnormal airflow to cause a significant deformation, but it should not be too small to prevent false triggering of normal breathing airflow. After research on oral airflow dynamics and simulation tests, a spring coefficient of 0.5-2N / m is more appropriate. The dial plate 807 contacts the dial rod 803 during rotation to drive the dial rod 803 to rotate, and the dial rod 803 drives the inner ring body 801 to rotate. A rotation limiting groove that cooperates with the dial rod 803 is provided in the liquid outlet cavity 201, so that the inner ring body 801 can be fixedly rotated at a certain angle and stop rotating, so that the liquid outlet micropore 202 is staggered with the through hole 802 to achieve the blocking of the liquid outlet micropore 202, and can promptly and quickly stop the care solution from continuing to flow out, thereby preventing the care solution from flowing into the respiratory tract of the child and achieving the function of preventing choking.

[0050] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
