Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, and in particular to a fixation device for nebulization of children. Background Technology

[0002] Nebulized inhalation therapy uses a nebulizer to disperse medication into tiny droplets or particles, suspending them in a gas and delivering them into the respiratory tract and lungs to humidify the airways and treat respiratory inflammation. Children with symptoms such as coughing often receive nebulized medication. Currently, when children undergo nebulization therapy, parents typically hold the nebulizer and cover the child's mouth and nose with the mask. However, children have poor self-control and may be afraid of new things, requiring parents to hold the child with one hand and hold the nebulizer with the other, which is not conducive to calming the child and leads to poor treatment effectiveness. Alternatively, the elastic straps on the mask can be used to secure it to the child's cheeks, but single elastic straps are not only unstable but can also excessively compress the child's cheeks, causing discomfort, increasing resistance, and affecting treatment. Therefore, there is an urgent need for a nebulization fixation device for children to solve these problems. Summary of the Invention

[0003] The present invention aims to provide a fixing device for children's nebulization, so as to solve the problem of poor fixing effect of existing nebulizers.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A fixing device for children's nebulization includes a fixing block and an elastic clamp. The elastic clamp is connected to the fixing block via an adjusting component. A gear column and a rack are respectively installed in the cavity of the fixing block. Two sets of racks are arranged opposite each other. The gear column is located between the two sets of racks and meshes with each other. A worm gear is provided at the bottom end of the gear column and meshes with a worm. The worm passes through the fixing block. A fixing frame is provided at the end of the rack. A movable frame is installed on the fixing frame. A compression spring is sleeved on the movable frame and is located between the fixing frame and the movable frame. The end of the movable frame is connected to a first arc-shaped plate. A head clamp is provided on the first arc-shaped plate. A second arc-shaped plate and a positioning pin are respectively installed in the first arc-shaped plate. Multiple sets of positioning holes are opened on the second arc-shaped plate. A positioning spring is sleeved on the positioning pin, and one end of the positioning pin passes through one set of positioning holes.

[0006] Furthermore, the adjustment assembly includes a lead screw and a moving block. The lead screw passes through the base on the top surface of the fixed block, and the moving block is sleeved on the lead screw with its bottom surface in contact with the top surface of the fixed block. Two sets of compression springs and connecting rods are respectively inserted into the moving block. One end of the compression spring is connected to the connecting rod, and the other end of the connecting rod is connected to the elastic clamp.

[0007] Furthermore, knobs are provided at the ends of both the lead screw and the worm gear.

[0008] Furthermore, the movable frame is rotatably connected to the first arc-shaped plate via a connecting shaft. The first arc-shaped plate is provided with an adjusting bolt, the end of which passes through the connecting shaft.

[0009] Furthermore, a sponge pad is provided on the head clamp, and elastic bands are provided at both ends of the head clamp. The elastic bands are connected to the first arc plate, and soft pads are provided on both the first arc plate and the second arc plate.

[0010] Furthermore, the head clip is equipped with decorative ears, and a magnetic block is placed between the decorative ears and the head clip. A support rod is inserted through one of the movable frames, and a kaleidoscope is placed at the top of the support rod.

[0011] The principles and beneficial effects of the technical solution are as follows:

[0012] This invention provides a fixation device for nebulization of children. An elastic clip secures the nebulizer to the device. Adjusting the worm gear, under the action of the worm wheel and gear column, causes relative movement of two sets of racks, thereby changing the width between the two sets of first arc-shaped plates to adapt to the width of the child's cheeks. The second arc-shaped plate can extend and retract within the first arc-shaped plate, thus changing the total length formed by the first and second arc-shaped plates, allowing the second arc-shaped plate to better fit the back of the child's head. Pulling the first arc-shaped plate moves the moving frame, compressing the first compression spring, thereby widening the distance between the two sets of first arc-shaped plates, making it easier for the operator to put the device on the child's head. After releasing the first arc-shaped plate, the first compression spring returns to its original position, allowing the first and second arc-shaped plates to fit against the child's cheeks. The head clip clamps onto the child's head, forming a two-way fixation, improving stability. Furthermore, the device is adjustable to accommodate children of different sizes, avoiding excessive pressure on the child's cheeks and improving the fixation effect. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-4 As shown, a fixing device for children's nebulization includes a fixing block 1 and an elastic clip 26. The elastic clip 26 is connected to the fixing block 1 through an adjusting component. A gear column 17 and a rack 20 are respectively installed in the cavity inside the fixing block 1. Two sets of racks 20 are arranged opposite each other. The gear column 17 is located between the two sets of racks 20 and meshes with each other. A worm gear 18 is provided at the bottom end of the gear column 17. The worm gear 18 meshes with a worm 19. The worm 19 is installed inside the fixing block 1. Through the unidirectional transmission of the worm gear 18 and the worm 19, the position of the rack 20 can be easily adjusted, and displacement when not adjusted can be avoided, which facilitates adjustment and improves stability. A fixing frame 21 is provided at the end of the rack 20. A movable frame 24 is installed on the fixing frame 21. A compression spring 25 is fitted onto the fixed frame 21 and the movable frame 24. The compression spring 25 compresses the movable frame 24, thereby providing clamping force to the first arc plate 2, making it fit better against the child's cheek and preventing loosening. The end of the movable frame 24 is connected to the first arc plate 2. A head clamp 4 is provided on the first arc plate 2. A second arc plate 3 and a positioning pin 5 are respectively inserted into the first arc plate 2. Multiple sets of positioning holes 7 are opened on the second arc plate 3. A positioning spring 6 is fitted over the positioning pin 5. One end of the positioning pin 5 is inserted into one set of positioning holes 7. By cooperating with the positioning hole 7, the extension length of the second arc plate 3 can be easily adjusted, thereby adjusting the total length of the device.

[0020] In use, firstly, the nebulizer cartridge on the nebulizer is clamped and fixed by the elastic clip 26, so that the nebulizer mask is located in the center of the fixing block 1. Then, the worm gear 19 is rotated, which drives the worm wheel 18 to rotate. The worm wheel 18 drives the gear column 17 to move in opposite directions within the fixing block 1, thereby changing the width between the two sets of first arc plates 2 to roughly adapt to the width of the child's face. After stopping the rotation of the worm gear 19, the gear column 17 cannot be rotated due to the unidirectional transmission between the worm wheel 18 and the worm gear 19. This fixes the positions of the two sets of first arc-shaped plates 2. Then, the positioning pin 5 is lifted out of the positioning hole 7, releasing the lock on the second arc-shaped plate 3. The second arc-shaped plate 3 is then extended or retracted into the first arc-shaped plate 2, changing its length and thus altering the total length formed by the first arc-shaped plate 2 and the second arc-shaped plate 3, allowing it to better fit the back of the child's head. Under the action of the positioning spring 6, the positioning pin 5 is reinserted into the corresponding positioning hole 7, fixing the second arc-shaped plate 3. After adjustment, the two sets of first arc-shaped plates 2 are pulled to move... The moving frame 24 moves on the fixed frame 21 and compresses the first compression spring 25, opening the two sets of first arc-shaped plates 2. This allows the operator to easily place the device over the child's cheek. After slowly releasing the two sets of first arc-shaped plates 2, the moving frame 24 returns to its original position under the action of the first compression spring 25, causing the two sets of first arc-shaped plates 2 to move towards each other and clamp onto the child's cheek. At this time, the nebulizer mask is positioned over the child's mouth and nose, and the head clip 4 is also attached to the child's head. This replaces the traditional handheld or single-rope fixation method, freeing the parents' hands. It can better soothe the child's emotions, and fix the device through bidirectional support, improving the stability of the fixation and preventing the device from falling off due to the child's movement, thus affecting the treatment. At the same time, after the device is clamped and fixed on the child's cheek, the operator can rotate the worm gear 19 to move the rack 20, and make fine adjustments to the position of the two sets of first arc plates 2, so that the clamping force of the first arc plates 2 on the child's cheek is kept within a suitable range, avoiding excessive clamping that may cause pressure on the child, leading to discomfort, increasing the child's resistance, and affecting the treatment effect.

[0021] In this embodiment, the adjustment component includes a lead screw 9 and a movable block 28. The lead screw 9 passes through a base on the top surface of the fixed block 1, and the movable block 28 is sleeved on the lead screw 9 with its bottom surface in contact with the top surface of the fixed block 1. Two sets of compression springs 29 and connecting rods 27 are respectively inserted into the movable block 28. One end of the compression spring 29 is connected to one end of the connecting rod 27, and the other end of the connecting rod 27 is connected to the elastic clip 26. After the device is worn on the child's cheek, the compression spring 29 ensures that the nebulizer mask on the elastic clip 26 is always pressed tightly against the child's mouth and nose, thus improving the nebulization treatment effect. By rotating the lead screw 9, the position of the movable block 28 on the top surface of the fixed block 1 can be adjusted, thereby adjusting the compression force of the compression spring 29 on the connecting rod 27. This prevents the mask from being pressed too tightly against the child's mouth and nose, which could lead to excessive leakage of nebulized drug gas or excessive pressure from the mask on the child's mouth and nose, causing discomfort.

[0022] In this embodiment, both the lead screw 9 and the worm gear 19 are equipped with knobs 8 at their ends. The knobs 8 allow operators to easily adjust the lead screw 9 and the worm gear 19, saving time and effort.

[0023] In this embodiment, the movable frame 24 is rotatably connected to the first arc-shaped plate 2 via a connecting shaft 22. An adjusting bolt 23 is provided on the first arc-shaped plate 2, with its end passing through the connecting shaft 22. By loosening the adjusting bolt 23, the first arc-shaped plate 2 is locked, allowing it to rotate around the connecting shaft 22. This adjusts the angle of the first arc-shaped plate 2 relative to the fixed block 1, thereby adjusting the clamping angle so that the nebulizer mask is positioned at the child's mouth and nose, ensuring the therapeutic effect. After adjustment, tightening the adjusting bolt 23 locks the device in place.

[0024] In this embodiment, the head clip 4 is provided with a sponge pad 12, and elastic bands 15 are provided at both ends of the head clip 4. The elastic bands 15 are connected to the first arc-shaped plate 2, and soft pads 16 are provided on both the first arc-shaped plate 2 and the second arc-shaped plate 3. The sponge pad 12 can increase the comfort of the head clip 4 when it is fixed on the child's head. The ends of the elastic bands 15 are attached with Velcro. Adjusting the length of the elastic bands 15 can adjust the position of the head clip 4 so that it is used at the height of the child's head, thereby improving wearing comfort. The soft pads 16 are made of skin-friendly material and come into direct contact with the child's cheeks, which can avoid allergies and increase comfort while reducing the child's resistance.

[0025] In this embodiment, the head clip 4 is provided with decorative ears 13, and a magnetic block 14 is provided between the decorative ears 13 and the head clip 4. A support rod 10 is inserted through a set of movable frames 24. The bottom of the support rod 10 is also fixed in the movable frame 24 by magnetic attraction. The support rod 10 is a shaped tube that can be bent at will and maintain its corresponding shape. A kaleidoscope 11 is provided at the top of the support rod 10. The decorative ears 13 can beautify the device, attract the child's attention, and reduce their resistance. They are also magnetically fixed by the magnetic block 14, allowing for quick assembly and disassembly. Different styles of decorative ears 13 can be changed according to the child's preferences. When the child wears the device for nebulization treatment, the support rod 10 is bent so that the kaleidoscope 11 is located at the child's eyes, allowing the child to observe the scene inside the kaleidoscope 11 and attracting their attention. When not in use, the support rod 10 can be removed. Through multiple sets of interesting decorations, the child's acceptance of the device is improved, making treatment more convenient.
