Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to anti-aspiration tableware for patients with moderate to severe respiratory failure. Background Technology

[0002] Respiratory failure is a serious respiratory dysfunction commonly seen in patients with stroke, pneumonia, and asthma. Moderate to severe cases are at extremely high risk of aspiration due to weakened airway protection, impaired swallowing coordination, and a diminished cough reflex. Aspiration, the entry of food, liquids, or oropharyngeal secretions into the airway below the glottis, is the main cause of aspiration pneumonia. Aspiration pneumonia can drastically worsen a patient's condition, prolong hospital stays, and increase mortality, making it a serious complication that urgently needs to be prevented in clinical practice.

[0003] Currently, clinical feeding for such patients mainly relies on nasogastric tubes or parenteral nutrition, completely avoiding oral feeding. However, this non-physiological feeding method not only causes significant physical and psychological suffering for patients (such as nasal discomfort and loss of the pleasure of eating), but may also lead to a series of complications (such as catheter-related infections, intestinal flora imbalance, and mucosal atrophy), and fails to meet the patients' intrinsic need to improve their nutritional status, maintain swallowing function, and enhance their quality of life through oral feeding.

[0004] When patients are in stable condition, conscious, and attempting oral feeding, existing ordinary tableware has significant defects and risks: First, its capacity and depth are not suitable for the small, safe bolus size of food for patients, making it easy to feed too much at once; second, patients have requirements for the food they eat, requiring it to be viscous to avoid choking; third, patients also need to pay attention to the flow rate of the liquid when drinking water to avoid choking.

[0005] Therefore, there is a need for a type of tableware designed specifically for patients with moderate to severe respiratory failure to prevent aspiration. This tableware should be able to adjust the capacity of the spoon head while filtering the water in the food to prevent choking, and the straw should have a reduced flow rate to facilitate drinking. This will help patients rebuild their confidence and ability to eat orally and improve their nutritional status and quality of life. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing tableware mentioned in the background art cannot adjust the capacity of the spoon head and the viscosity of the food, which leads to patients choking due to excessive consumption.

[0007] To address the aforementioned technical issues, an anti-aspiration tableware design for patients with moderate to severe respiratory failure is proposed. This is achieved through the following technical solution: Anti-aspiration tableware for patients with moderate to severe respiratory failure includes a spoon, a straw, a control component, and an adjustment component. The straw is mounted on the spoon, and the control component is located at one end of the spoon handle and connected to the adjustment component located inside the handle. The adjustment component can adjust the capacity of the spoon head under the action of the control component.

[0008] In this invention, the capacity of the spoon head can be adjusted by the adjustment component, so as to take out the appropriate amount of food according to the actual needs of the patient. At the same time, the water in the food can be removed through the hole in the spoon head, so as to avoid the patient choking due to taking too much food at one time and containing too much water. This helps the patient rebuild confidence and ability to eat orally, and improves their nutritional status and quality of life.

[0009] In a preferred embodiment of the present invention, the control component includes a knob, a first transmission rod, and a first bevel gear. The first transmission rod is disposed inside the spoon handle, the knob is disposed at the end of the spoon handle and connected to the first transmission rod, and the first bevel gear is disposed on the first transmission rod. Rotating the knob can drive the first bevel gear to rotate. With this configuration, the adjustment component can be adjusted through the control component.

[0010] In a preferred embodiment of the present invention, the adjusting assembly includes an adjusting plate, a second transmission rod, and a second bevel gear. The second transmission rod is disposed inside the spoon handle, and the second bevel gear is disposed on the second transmission rod. One end of the adjusting plate is connected to the second transmission rod, and the other end extends into the spoon head. When the second bevel gear rotates, it can drive the adjusting plate to rotate inside the spoon head. By adjusting the adjusting plate, the capacity of the spoon head can be adjusted.

[0011] In a preferred embodiment of the present invention, the adjusting plate is made of polypropylene (PP), which is safe and non-toxic when in contact with food inside the spoon.

[0012] In a preferred embodiment of the present invention, the spoon includes a spoon head, a spoon handle, and a limiting device. The spoon head and the spoon handle are connected to each other, and the limiting device is disposed inside the spoon handle. The limiting device limits the position of the adjusting plate. By setting the limiting device, the position of the adjusting plate is limited, preventing the position of the adjusting plate from changing due to scooping food.

[0013] In a preferred embodiment of the present invention, the limiting device includes a push block, a limiting strip, and a limiting plate. The limiting strip is disposed on the first transmission rod, and the limiting plate is connected to the push block and disposed on the spoon handle. Pushing the push block can cause the limiting plate and the limiting strip to engage and disengage. When the push block engages with the limiting strip, it prevents the first transmission rod from rotating, thereby limiting the position of the adjusting plate and limiting the capacity of the spoon head.

[0014] In a preferred embodiment of the present invention, the spoon handle is cylindrical, which makes it easy for patients to hold.

[0015] In a preferred embodiment of the present invention, the spoon head and spoon surface are semi-circular. This design allows the adjusting plate to rotate around the second transmission rod, thereby adjusting the capacity of the spoon head.

[0016] In a preferred embodiment of the present invention, the spoon head is provided with a sieve hole to facilitate the filtration of water and increase the viscosity of the food.

[0017] In a preferred embodiment of the present invention, the straw is made of food-grade silicone, which is soft and food-grade, making it convenient for patients to use.

[0018] The advantages of this utility model compared with the prior art are: The capacity of the spoon head can be adjusted by adjusting the components, so that the appropriate amount of food can be served according to the patient's actual needs. At the same time, the water in the food can be removed through the holes in the spoon head, so as to avoid the patient choking due to too much food or too much water in the food served at one time. This helps patients rebuild their confidence and ability to eat orally, and improve their nutritional status and quality of life. Attached Figure Description

Detailed Implementation

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0021] Definition: The spoon head 11 is located on the left, and the spoon handle 12 is located on the right.

[0022] like Figure 1 As shown, the anti-aspiration tableware designed for patients with moderate to severe respiratory failure includes a spoon 1, a straw 2, a control component 3, and an adjustment component 4. The straw 2 is set on the spoon 1, and the control component 3 is set at one end of the spoon handle 12 and connected to the adjustment component 4 set in the spoon handle 12.

[0023] The main function of spoon 1 is to scoop food for the patient to eat.

[0024] The main function of straw 2 is to provide water for the patient, while preventing patients with moderate to severe respiratory failure from choking when drinking water.

[0025] The main function of the control component 3 is to act as the control end of the adjustment component 4. The control component 3 can drive the adjustment component 4 to adjust the adjustment plate 41.

[0026] The adjustment component 4 works in conjunction with the control component 3. The adjustment component 4, as the adjustment end, is controlled by the control component 3, which drives the adjustment component 4 to adjust the adjustment plate 41. The main function of the adjustment component 4 is to limit the amount of food scooped at one time, so as to prevent the patient from choking due to excessive food scooping at one time.

[0027] like Figure 3 , 4 As shown, the spoon 1 includes a spoon head 11, a spoon handle 12 and a limiting device 13. The spoon head 11 and the spoon handle 12 are connected. The spoon handle 12 is cylindrical in shape, which is convenient for patients to hold. A cavity is opened in the center of the spoon handle 12 and an installation groove 121 is opened on the surface. The right side of the spoon handle 12 is open. The limiting device 13 limits the adjustment plate 41.

[0028] like Figure 2 , 3 As shown, the control component 3 includes a knob 31, a first transmission rod 32, and a first bevel gear 33. One end of the first transmission rod 32 is rotatably connected to the inner wall of the cavity on the left side of the spoon handle 12, and the other end is fixedly connected to the knob 31 along the right side of the spoon handle 12. The knob 31 matches the shape of the spoon handle 12 and is rotatably connected to the open right side of the spoon handle 12. The first bevel gear 33 is fixed on the first transmission rod 32. The control component 3 is the control end. The control component 3 adjusts the first bevel gear 33 by rotating the knob 31 to form a control engagement with the adjustment component 4.

[0029] The adjusting assembly 4 includes an adjusting plate 41, a second transmission rod 42, and a second bevel gear 43. The second transmission rod 42 is vertically and rotatably connected to the inner wall of the spoon handle 12. The second bevel gear 43 is fixed to one end of the second transmission rod 42 and meshes with the first bevel gear 33. The other end of the second transmission rod 42 is fixedly connected to a section of the adjusting plate 41 made of polypropylene (PP). The other end of the adjusting plate 41 extends into the spoon head 11, and the adjusting plate 41 cooperates with the spoon head 11.

[0030] The control component 3 controls the adjustment component 4 as follows: When the knob 31 is rotated, the first transmission rod 32 is driven to rotate, and the first bevel gear 33 fixed on the first transmission rod 32 will also rotate. The second bevel gear 43 meshing with the first bevel gear 33 will also rotate at this time, driving the second transmission rod 42 to rotate. The second transmission rod 42 synchronously drives the adjustment plate 41 to rotate in a semi-circular motion around the second transmission rod 42. The knob 31 controls the adjustment plate 41 to cooperate with the spoon head 11.

[0031] The working relationship between the adjusting plate 41 and the spoon head 11 is achieved as follows: the adjusting plate 41 is placed vertically to divide the inside of the spoon head 11 into two spaces. When the adjusting plate 41 rotates in a semi-circular motion around the second transmission rod 42, the size of the two spaces inside the spoon head 11 is changed at the same time. The size of the two spaces inside the spoon head 11 can be adjusted according to actual needs.

[0032] In order to enable the adjusting plate 41 to cooperate with the spoon head 11, the end of the adjusting plate 41 that extends into the spoon head 11 has the same shape as the vertical cross-section of the entire spoon head 11. The vertical dimension of the adjusting plate 41 is slightly higher than the depth of the spoon head 11, and the adjusting plate 41 is in contact with the inner wall of the spoon head 11.

[0033] In order for the adjusting plate 41 to achieve semi-circular rotation within the spoon head 11, the spoon surface of the spoon head 11 is semi-circular with a semi-circular gap at the center, which is connected to the spoon handle 12. The diameter edge of the semi-circular shape of the spoon head 11 is perpendicular to the spoon handle 12. The center of the semi-circular shape of the spoon head 11 coincides with the center of the second transmission rod 42, and the radius of the spoon head 11 is the same as the dimension of the adjusting plate 41 in the left and right directions. This allows the adjusting plate 41 to cooperate with the spoon head 11 when it rotates semi-circularly around the second transmission rod 42.

[0034] A groove 123 is provided at the extension of the spoon handle 12 on the adjusting plate 41. The groove 123 allows the adjusting plate 41 to rotate semi-circularly along the second transmission rod 42 without obstruction.

[0035] To avoid cleaning difficulties after use due to the above structure, the spoon head 11 and the spoon handle 12 are detachably connected by screws, making it easy to disassemble the spoon head 11 and clean its interior.

[0036] like Figure 2 , 3 As shown, the limiting device 13 includes a push block 131, a limiting strip 132, and a limiting plate 133. The cuboid limiting strip 132 is fixed on the first transmission rod 32. The push block 131 and the limiting plate 133 are made of polypropylene (PP). The push block 131 is a cube, and the limiting plate 133 is in the shape of a "7". The whole is snapped into the mounting groove 121 on the spoon handle 12. Pushing the push block 131 can drive the limiting plate 133 to engage and disengage with the limiting strip 132.

[0037] A hole 122 is provided in the mounting groove 121 of the spoon handle 12. The hole 122 has a structure with slightly larger space on the left and right sides and slightly smaller space in the middle. The left and right sides are "open" and "closed" respectively. A limit device 13 is installed in the mounting groove 121.

[0038] The limiting device 13 achieves its limiting engagement with the adjusting plate 41 as follows: In the "closed" state, one end of the limiting plate 133 engages with the limiting strip 132 to restrict the rotation of the first transmission rod 32, while the other end passes through the hole 122 and is fixedly connected to the push block 131. Pushing the push block 131 causes the limiting plate 133 to be squeezed to the "open" position. Since the diameter of the hole 122 is slightly smaller, the push block 131 will remain at the "open" position to prevent unplanned movement. At this time, the limiting plate 133 leaves the limiting strip 132 and releases the engagement. Rotating the knob 31 can drive the first transmission rod 32 to rotate. The limiting device 13 restricts the angle of the adjusting plate 41 by preventing the first transmission rod 32 from rotating.

[0039] In order to enable the limiting device 13 to limit the adjustment plate 41 at multiple angles, a plurality of limiting strips 132 that cooperate with the limiting plate 133 are fixed at intervals on the surface of the first transmission rod 32.

[0040] like Figure 2 As shown, in order to facilitate the installation of the limiting device 13, the adjusting component 4 and the control component 3, an installation port is provided in the horizontal direction of the spoon handle 12, dividing the spoon handle 12 into two parts. After installation, the two parts can be fixed with screws.

[0041] like Figure 3 As shown, to prevent patients from choking while eating, a perforation is provided at the bottom of the spoon head 11 to facilitate the filtering of water from the food and increase the viscosity of the food.

[0042] The straw 2 is made of food-grade silicone and is placed in the cavity on the lower surface of the spoon handle 12. When using it, the straw 2 is pulled out of the cavity and used to drink water. The silicone material is soft and safe, and the straw 2 is preferably 5mm in diameter. This small diameter design reduces the flow rate of water and avoids choking.

[0043] The working principle and usage process of this utility model: When using this tableware, the patient adjusts the limiting device 13 to the "on" state, rotates the knob 31 to adjust the capacity of the spoon head 11 according to their actual needs, and after adjustment, pushes the push block 131 to adjust the limiting device 13 to the "off" state. Then, the patient scoops up food and eats. When the patient needs to drink water, the straw 2 is pulled out and placed in the cup to drink water.

[0044] This device allows the capacity of the spoon head 11 to be divided by rotating the knob 31, so that patients can choose the appropriate side to eat from according to their needs. The limiting device 13 can prevent the adjustment plate 41 from moving during the process of scooping food, which would cause changes in the capacity of the spoon head 11. At the same time, the leakage hole of the spoon head 11 can filter water to ensure the viscosity of the food. The straw 2 is made of small-diameter food-grade silicone material, which limits the flow rate of water for patients to drink, making it more practical and safe. This device can be used by patients who are left- or right-handed, and it can also help exercise finger dexterity, help patients rebuild their confidence and ability to eat orally, and improve their nutritional status and quality of life.

[0045] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
