Description

Technical Field

[0001] The invention belongs to the technical field of oral care, and in particular relates to an oral care tool for critically ill patients. Background Art

[0002] In clinical medicine, critically ill patients have a significantly reduced ability to clean their mouths due to their severe condition, long-term bed rest, unconsciousness or mechanical ventilation, which makes it very easy for bacteria, fungi and other microorganisms to breed, leading to complications such as oral infection and ventilator-associated pneumonia.

[0003] Traditional oral care methods for critically ill patients mostly rely on manual operations by medical staff, using simple tools such as cotton balls and gauze for wiping and cleaning. Not only is the operation cumbersome, time-consuming and labor-intensive, but the cleaning effect is limited, and it is difficult to conduct comprehensive and effective care deep inside the oral cavity. In addition, during the care process, additional auxiliary tools are needed to open the patient's mouth, which increases the operation steps and the workload of medical staff. Although there are some oral care devices in the prior art, most of them have a single function and cannot realize the linkage operation of opening the mouth and flushing care, which makes it difficult to meet the efficient, convenient and comprehensive oral care needs of critically ill patients. Summary of the invention

[0004] In order to solve the above-mentioned problems, the present invention provides an oral care tool for critically ill patients, which realizes the seamless connection between stretching the oral cavity and flushing care. The operation process is coherent and smooth, and there is no need for medical staff to perform complicated step-by-step operations. At the same time, the delay effect of the delay part ensures that the care liquid is not sprayed until the mouth is fully stretched, thereby ensuring the effectiveness and accuracy of the care, and greatly improving the quality and efficiency of oral care for critically ill patients.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: an oral care tool for critically ill patients includes a casing, an opening component is connected to the outside of the casing, which can open the patient's oral cavity, and a flushing and care component is arranged on the casing. After the patient's oral cavity is opened, flushing and care are performed. The opening component is transmission-connected to the flushing and care component. After the patient's oral cavity is opened, flushing and care operations are performed, which is convenient for operation; the flushing and care component includes a push rod, a delay part and a flushing head, the push rod slides through the top wall and the bottom wall of the casing, the delay part is arranged in the casing, the delay part is connected to the push rod, the flushing head is connected to the bottom end of the push rod, the flushing head is connected to the bottom of the casing by a connecting pipe, the sliding of the push rod drives the flushing head to move, and at the same time, the delay part performs delayed extrusion control on the cavity care liquid stored in the casing; both side ends of the flushing head are fixedly connected with wedge blocks.

[0006] As a preferred technical solution of the present invention, the delay part includes a piston plate, a delay plate and a delay spring. The piston plate is slidably arranged in the casing, the piston plate is fixedly sleeved with the push rod, the delay plate is slidably arranged in the casing, the delay plate is slidably sleeved with the push rod, and the delay plate is located below the piston plate. The delay spring is connected between the delay plate and the piston plate. The push rod drives the piston plate to compress the delay spring first, and only after the spring reaches the limit compression state, the delay plate is driven to squeeze the care solution, thereby ensuring that the care solution enters the flushing head at the right time and accurately controlling the release rhythm of the care solution.

[0007] As a preferred technical solution of the present invention, a valve is installed on the connecting pipe. An initially closed valve is set on the connecting pipe. The valve will only open when the push rod drives the piston plate to compress the delay spring to the limit and generates sufficient pressure, thereby ensuring that the care liquid is sprayed out smoothly as planned after the mouth is stretched open and ready, avoiding leakage and accidental spraying.

[0008] As a preferred technical solution of the present invention, the expansion assembly includes an expansion frame and a expansion plate. The expansion frames are arranged in two groups relatively to each other and are located on both sides of the casing. A hinge shaft is arranged on the outer wall of the casing. The two groups of expansion frames are hinged to the hinge shaft, and a torsion spring is connected between the two groups of expansion frames. The inclined surface at the bottom end of the expansion frame is slidably connected to the inclined surface of the wedge block, and the expansion plate is fixedly connected to the bottom end of the expansion frame. The hinged expansion frame and the expansion plate are used in conjunction with the torsion spring and the wedge block to achieve automatic oral expansion when the push rod is pressed down.

[0009] As a preferred technical solution of the present invention, a plurality of nozzles are evenly arranged at the bottom of the flushing head, so that the patient's oral cavity can be fully covered and flushed from different angles during flushing care.

[0010] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects:

[0011] 1. The opening component is connected to the flushing and nursing component by transmission. Medical staff only need to operate the push rod to realize the continuous operation of oral opening and flushing nursing for patients. There is no need to use different tools respectively, which greatly simplifies the nursing process, saves operation time and improves nursing efficiency.

[0012] 2. There are multiple groups of nozzles at the bottom of the flushing head in the flushing care component, which can flush the patient's mouth from multiple angles to ensure that all parts of the mouth can be fully cleaned;

[0013] 3. The design of the delay part enables the oral care solution to be squeezed into the rinse head at the right time, ensuring the effective spraying and cleaning effect of the care solution;

[0014] 4. The automatic opening and flushing functions reduce the manual operation steps and labor intensity of medical staff during nursing, reduce the work pressure of medical staff, and also reduce the risk of oral injury to patients caused by improper manual operation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1-6 As shown, the oral care tool for critically ill patients provided by the present invention comprises a housing 1, an opening component 2 is connected to the outer side of the housing 1, and the oral cavity of the patient can be opened. A flushing care component 3 is arranged on the housing 1, and after the oral cavity of the patient is opened, flushing care is performed. The opening component 2 is connected to the flushing care component 3 by transmission, and after the oral cavity of the patient is opened, flushing care is performed, which is convenient for operation; the flushing care component 3 comprises a push rod 31, a delay part 32 and a flushing head 33, and the push rod 31 slides through the housing 1 The top and bottom walls of the housing 1, the delay part 32 is arranged in the housing 1, the delay part 32 is connected to the push rod 31, the flushing head 33 is connected to the bottom end of the push rod 31, the flushing head 33 is connected to the bottom of the housing 1 through a connecting pipe 4, a valve 41 is installed on the connecting pipe 4, a plurality of groups of nozzles 331 are evenly arranged at the bottom of the flushing head 33, the sliding of the push rod 31 drives the flushing head 33 to move, and at the same time, the delay part 32 performs delayed extrusion control on the cavity care liquid stored in the housing 1; both side ends of the flushing head 33 are fixedly connected with wedge blocks 5.

[0025] like Figures 5-6 As shown, the delay part 32 includes a piston plate 321, a delay plate 322 and a delay spring 323. The piston plate 321 is slidably arranged in the housing 1. The piston plate 321 is fixedly sleeved with the push rod 31. The delay plate 322 is slidably arranged in the housing 1. The delay plate 322 is slidably sleeved with the push rod 31, and the delay plate 322 is located below the piston plate 321. The delay spring 323 is connected between the delay plate 322 and the piston plate 321. The cavity care liquid is filled between the delay plate 322 and the housing 1, pushing the push rod 31 downward. The push rod 31 drives the piston plate 321 to move downward, and the piston plate 321 first squeezes the delay spring 323. When the delay spring 323 is compressed to the limit, it can drive the delay plate 322 to move downward to squeeze the oral care liquid through the connecting tube 4 into the flushing head 33, thereby playing a delay role. In the initial state, the valve 41 is in a closed state. After the push rod 31 drives the piston plate 321 to squeeze the delay spring 323 to the limit compression state, its pressure can push open the valve 41, and the cavity care liquid can pass smoothly.

[0026] As shown Figures 1-5 in the figure, the spreading component 2 includes a spreading frame 21 and a supporting plate 22. Two sets of spreading frames 21 are oppositely arranged and located on both sides of the casing 1. A hinge shaft 23 is provided on the outer side wall of the casing 1. Both sets of spreading frames 21 are hinged to the hinge shaft 23, and a torsion spring 24 is connected between the two sets of spreading frames 21. The bottom inclined surface of the spreading frame 21 is slidably connected to the inclined surface of the wedge block 5. The supporting plate 22 is fixedly connected to the bottom end of the spreading frame 21. While the pushing rod 31 moves downward, it drives the wedge blocks 5 on both sides of the flushing head 33 to move downward. The wedge blocks 5 move downward to push open the spreading frames 21 on both sides. The two sets of spreading frames 21 drive the supporting plate 22 to open the patient's oral cavity so that the flushing head 33 can penetrate for flushing and nursing.

[0027] During specific use, an appropriate amount of oral care solution is injected into the casing 1 to make the care solution fill the space between the delay plate 322 and the casing 1. Check whether the valve 41 on the connecting pipe 4 is in a closed state to ensure that the care solution will not leak under the initial state;

[0028] Place the care tool in a suitable position. The medical staff holds the casing 1 and pushes the pushing rod 31 downward. The pushing rod 31 drives the wedge blocks 5 on both sides of the flushing head 33 to move downward. The wedge blocks 5 contact and slide on the bottom inclined surface of the spreading frame 21, pushing open the spreading frames 21 on both sides, driving the supporting plate 22 to open the patient's oral cavity to a suitable opening size. At the same time, during the continuous downward pushing of the pushing rod 31, the pushing rod 31 drives the piston plate 321 to move downward. The piston plate 321 first compresses the delay spring 323. When the delay spring 323 is compressed to the limit, the piston plate 321 drives the delay plate 322 to move downward, squeezing the oral care solution in the casing 1. At this time, the pressure of the care solution pushes open the valve 41 on the connecting pipe 4, and the care solution enters the flushing head 33 through the connecting pipe 4 and is sprayed out from multiple groups of nozzles 331 arranged uniformly at the bottom of the flushing head 33 to conduct a comprehensive flushing of the patient's oral cavity;

[0029] After completing the flushing and nursing, slowly pull the pushing rod 31 upward to make the spreading frame 21 reset under the action of the torsion spring 24, and the supporting plate 22 releases the patient's oral cavity. At the same time, the piston plate 321 and the delay plate 322 reset under the elastic force of the delay spring 323, and the valve 41 closes, completing an oral care operation. Clean the care tool to prepare for the next use.

[0030] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
