Description

Technical Field

[0001] This invention relates to the field of respiratory drug inhalation equipment technology, and more specifically to a respiratory drug inhalation auxiliary device. Background Technology

[0002] Inhaled medication is the core and preferred method of drug administration in respiratory medicine for treating a variety of diseases. Inhaled medication can act directly on the target organ, and the local drug concentration is high, which can make it more effective and faster. Because it is delivered directly, the required drug dose is much smaller than that of oral or injected medication. Moreover, very little drug enters the bloodstream after being absorbed by the lungs, which greatly avoids systemic side effects. This is especially important for patients who need to use hormones for a long time. It can significantly reduce common side effects of oral hormones such as obesity, osteoporosis, and hyperglycemia. It is often used to treat diseases such as asthma, obstructive pulmonary disease, bronchiectasis, interstitial lung disease, and rhinitis.

[0003] When administering medication, patients typically need to wear a breathing mask to deliver the medication or clean air into their nasal cavity via airflow. However, observations have shown that patients may experience discomfort due to the elastic straps of the breathing mask constricting their ears. For patients such as children and the elderly who lack basic medical safety awareness, they may inadvertently pull off the breathing mask due to discomfort, resulting in insufficient inhalation and administration of the medication. Therefore, current technology lacks devices that can secure the breathing mask to the patient's face for assisted breathing.

[0004] Therefore, the present invention provides a respiratory drug inhalation aid device to solve the above-mentioned problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a respiratory drug inhalation assistance device to solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A respiratory medication inhalation aid device includes an inner coil, an outer coil, and a middle coil;

[0008] Outer ring: The outer ring is fixedly connected to the base;

[0009] Inner rotating ring: There are two inner rotating rings, each rotating inside the two ends of the outer ring. A headrest is fixedly connected between the lower inner ends of the two inner rotating rings, and an attachment ring is fixedly connected to the inner side of the inner rotating ring.

[0010] The middle rotating ring rotates inside the outer ring and is located between the two inner rotating rings. Both ends of the middle rotating ring are fixedly connected to an arc-shaped rod. The first sliding sleeve, the second sliding sleeve, and the third sliding sleeve are movably fitted on the outside of the arc-shaped rod from top to bottom. There is no less than one first sliding sleeve. The uppermost first sliding sleeve is fixedly connected to the end of the arc-shaped rod, the lowermost first sliding sleeve is fixedly connected to the second sliding sleeve, and the second sliding sleeve is fixedly connected to the third sliding sleeve. An elastic rope moves through the first sliding sleeve, the second sliding sleeve, and the third sliding sleeve. A breathing mask is fixedly tied between two elastic ropes.

[0011] A connecting rod is fixedly connected to the side of the second sliding sleeve, and a chin sleeve is fixedly connected between the two connecting rods;

[0012] The third sliding sleeve has a button on its outer movable sleeve. A second spring is fixedly connected between the third sliding sleeve and the button. A first locking block is integrally formed on the side of the button. The inner side of the outer ring, the outer edge of the attachment ring, and the outer edge of the central ring are all decorated with lace. The first locking block is movably inserted into the lace of the attachment ring and the central ring. A loop is installed at the end of the button. The inner edge of the loop moves around the center of the outer ring and passes through the end of the button. The center of the loop and the center of the outer ring are on the same straight line. A second locking block is integrally formed at the end of the loop. The second locking block is movably inserted into the lace of the outer ring.

[0013] With the above technical solution, when the button is pushed down, the first sliding sleeve, the second sliding sleeve, and the third sliding sleeve all move down. The third sliding sleeve pushes the elastic cord down, which can place the breathing mask on the patient's face. When the elastic cord continues to move down, it can keep the breathing mask tightly against the patient's face. Moreover, the elastic cord is not directly fixed to the patient's head, so as to avoid damage to the patient's ears and reduce the patient's discomfort. In addition, the height of the third sliding sleeve can be adjusted, so that the tightness and angle of the elastic cord can be adjusted according to the patient's face size, face height, etc., to improve the patient's comfort.

[0014] At the same time, the second sliding sleeve drives the connecting rod to move down, and the connecting rod drives the chin sleeve to move down, so that the chin sleeve is restricted on the patient's chin, reducing the risk of the patient breaking free of the device;

[0015] Furthermore, the lower end of the elastic cord is restricted in height by the third sliding sleeve, allowing the lower end of the elastic cord to reach the patient's earlobe, and the chin strap is restricted in height by the second sliding sleeve, allowing the height of the chin strap to reach the patient's chin. In other words, the lower end of the elastic cord is lower than the height of the chin strap, which is more in line with the position of the human facial organs.

[0016] Furthermore, the rotating ring allows for adjustment of the angle of the breathing mask and chin strap, ensuring that the breathing mask and chin strap remain stably worn on the patient's face even when the patient is lying on the headrest in different directions.

[0017] After the breathing mask is put on, the second spring pushes the button, causing the first locking block to engage with the lace trim of the inner and middle rotating rings, and the second locking block to engage with the lace trim of the outer ring. This fixes the button, the breathing mask, and the chin strap. Furthermore, the inner edge of the loop moves around the center of the outer ring and passes through the end of the button, allowing the inner and middle rotating rings to rotate relative to the outer ring at a certain angle. This allows the breathing mask, chin strap, and headrest to rotate at a certain angle, enabling the patient's head to rotate to a certain extent during medication inhalation, rather than being completely fixed, thus improving comfort.

[0018] Preferably, there is a gap between one of the inner and outer rings, and a connecting rod extends out from the gap and rotatably connects two turntables within the gap. The connecting rod passes through the turntables, and an organ plate is fixedly connected between the upper and lower ends of the two turntables. The organ plate moves within the gap between the inner and outer rings.

[0019] The above technical solution allows the turntable and accordion plate to cover the gap between the inner and outer rings without affecting the movement of the connecting rod.

[0020] Preferably, the outer ring is laterally movable into the base, and a locking assembly is installed at the end of the base. The outer ring is fixedly clamped between the base and the locking assembly. A buckle is fixedly connected to the lower side of the headrest. When the outer ring is inserted into the base, the other end of the buckle is laterally movable into the card holder, and the card holder is fixedly connected to the upper end of the base.

[0021] With the above technical solution, the buckle is fastened to the card holder, which can restrict the outer ring from moving up and down, and the locking component can restrict the outer ring from moving laterally. Thus, the outer ring can be detachably fixed to the base. When the patient is lying on the base, the outer ring can be put over the patient's head and then fixed.

[0022] Preferably, both the lower inner side of the buckle and the lower inner side of the card holder have rolling balls, the upper end of the base is arc-shaped and the center of the arc is on the same straight line as the center of the inner rotating circle, the balls inside the lower side of the buckle roll on the upper side of the base, the upper side of the buckle is arc-shaped and the center of the arc is on the same straight line as the center of the inner rotating circle, and the balls inside the lower side of the card holder roll on the upper end of the buckle.

[0023] Through the above technical solution, the buckle can rotate relative to the bracket and the base, and the ball bearings reduce friction, thereby supporting the headrest.

[0024] Preferably, the locking assembly includes a locking block and a third spring. The locking block is movably inserted into the upper side of the base, and the third spring is fixedly connected between the locking block and the base. The outer ring is fixedly clamped between the locking block and the base.

[0025] With the above technical solution, when medical staff press the locking block with their fingers, the third spring is compressed, and the locking block does not block the outer ring, so the outer ring can be moved. When medical staff remove their fingers from the locking block, the third spring extends, and the locking block blocks the outer ring, so the outer ring can be clamped and fixed, thereby realizing the fixation and movement of the outer ring.

[0026] Preferably, a fourth spring is fixedly connected between the upper end of the loop and the button, and between the lower end of the loop and the button;

[0027] Through the above technical solution, the fourth spring can push the button back to its original position, thereby driving the middle rotating ring and the inner rotating ring to rotate back to their original position. That is, after the patient's head moves the headrest, the headrest can have a tendency to rotate back to its original position, and the headrest can actively return to its original position when the patient's head returns to its original position.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. When the button is pushed down, the first, second, and third sliding sleeves all move down. The third sliding sleeve pushes the elastic cord down, which can place the breathing mask on the patient's face. As the elastic cord continues to move down, it can keep the breathing mask tightly against the patient's face. The elastic cord is not directly fixed to the patient's head, so as to avoid damage to the patient's ears and reduce the patient's discomfort. The height of the third sliding sleeve can be adjusted, so that the tightness and angle of the elastic cord can be adjusted according to the patient's face size, face height, etc., to improve the patient's comfort.

[0030] 2. At the same time, the second sliding sleeve drives the connecting rod to move downward, and the connecting rod drives the chin sleeve to move downward, so that the chin sleeve is restricted on the patient's chin, reducing the risk of the patient breaking free of the device;

[0031] 3. Furthermore, the lower end of the elastic cord is restricted in height by the third sliding sleeve, allowing the lower end of the elastic cord to reach the patient's earlobe, and the chin strap is restricted in height by the second sliding sleeve, allowing the height of the chin strap to reach the patient's chin. That is, the lower end of the elastic cord is lower than the height of the chin strap, which is more in line with the position of the human facial organs.

[0032] 4. Furthermore, the rotating ring can be used to adjust the angle of the breathing mask and chin cover, ensuring that the breathing mask and chin cover remain stably worn on the patient's face even when the patient is lying on the headrest in different directions.

[0033] 5. After the breathing mask is put on, the second spring pushes the button, causing the first locking block to engage with the lace trim of the attachment ring and the middle rotating ring, and the second locking block to engage with the lace trim of the outer ring. This fixes the button, the breathing mask, and the chin strap. Furthermore, the inner edge of the loop moves around the center of the outer ring and passes through the end of the button, allowing the inner and middle rotating rings to rotate relative to the outer ring at a certain angle. This allows the breathing mask, chin strap, and headrest to rotate at a certain angle, enabling the patient's head to rotate to a certain extent during drug inhalation, rather than being completely fixed, thus improving comfort.

[0034] In summary, this device allows for the administration of medication via respiration by placing a breathing mask over the patient's face without the elastic cord contacting the body, reducing patient discomfort. It also restrains the patient's head within the device, reducing the risk of the patient escaping the breathing mask. Furthermore, the tightness of the breathing mask, its orientation, and the rotation of the headrest can be adjusted to provide the patient with some head movement space, further reducing discomfort.

[0045] The following will refer to the attached reference. Figures 1 to 9 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0046] As attached Figure 1 - Appendix Figure 9 As shown, a respiratory medication inhalation aid device includes an inner rotating ring 5, an outer ring 6, and a middle rotating ring 21.

[0047] Outer Ring 6: Outer Ring 6 is circular, see Appendix Figure 1 and attached Figure 8 The lower end of the outer ring 6 moves laterally back and forth into the base 8. The end of the base 8 is equipped with a locking assembly 26. The outer ring 6 is clamped between the base 8 and the locking assembly 26, thereby making the outer ring 6 detachably fixed on the base 8.

[0048] Inner rotation 5: See appendix Figure 2 Appendix Figure 3 and attached Figure 8There are two inner rotating rings 5, which rotate within the front and rear ends of the outer ring 6 respectively. The centers of the inner rotating rings 5 ​​and the outer ring 6 are on the same straight line. A headrest 11 is fixedly connected between the lower inner ends of the two inner rotating rings 5. Two inner rotating rings 5 ​​are fixedly connected together by a headrest 11. The two inner rotating rings 5 ​​rotate synchronously. A soft pad 7 is fixedly connected to the upper side of the headrest 11. The soft pad 7 is made of latex or leather to increase the patient's comfort. A buckle 9 is fixedly connected to the lower side of the headrest 11. When the outer ring 6 is inserted into the base 8, the other end of the buckle 9 moves laterally into the card holder 10. The card holder 10 is fixedly connected to the upper end of the base 8. Rolling balls 29 roll on the lower side of both the buckle 9 and the card holder 10. The upper end of the base 8 is arc-shaped and its center is on the same straight line as the center of the inner rotating ring 5. The rolling balls 29 in the lower side of the buckle 9 roll on the upper side of the base 8. The upper side of the buckle 9 is arc-shaped and its center is on the same straight line as the center of the inner rotating ring 5. The rolling balls 29 in the lower side of the card holder 10 roll on the upper side of the end of the buckle 9. An attachment ring 20 is fixedly connected to the inner side of the inner rotating ring 5.

[0049] The intermediate rotating ring 21 rotates within the outer ring 6 and is located between the two inner rotating rings 5. Both ends of the intermediate rotating ring 21 are fixedly connected to an arc-shaped rod 15. The arc-shaped rod 15 is movably fitted with a first sliding sleeve 14, a second sliding sleeve 16, and a third sliding sleeve 19 from top to bottom. There is at least one first sliding sleeve 14. A first spring 17 is fixedly connected between the uppermost first sliding sleeve 14 and the end of the arc-shaped rod 15, between the lowermost first sliding sleeve 14 and the second sliding sleeve 16, and between the second sliding sleeve 16 and the third sliding sleeve 19. Each of the first sliding sleeve 14, the second sliding sleeve 16, and the third sliding sleeve 19 has a rope hole 27. An elastic rope 2 moves through the rope holes 27 of the first sliding sleeve 14, the second sliding sleeve 16, and the third sliding sleeve 19. A breathing mask 1 is fixedly tied between two elastic ropes 2.

[0050] A connecting rod 3 is fixedly connected to the side of the second sliding sleeve 16, and a chin sleeve 12 is fixedly connected between the two connecting rods 3.

[0051] The third sliding sleeve 19 has a button 13 movably mounted on its outer side. A second spring 18 is fixedly connected between the third sliding sleeve 19 and the button 13. A first locking block 22 is integrally formed on the side of the button 13. The inner side of the outer ring 6, the outer edge of the attachment ring 20, and the outer edge of the central rotating ring 21 are all decorated with lace 23. The first locking block 22 is movably locked into the lace 23 of the attachment ring 20 and the central rotating ring 21. A loop 24 is installed at the end of the button 13. The inner edge of the loop 24 moves around the center of the outer ring 6 and passes through the end of the button 13. The center of the loop 24 and the center of the outer ring 6 are on the same straight line. A fourth spring 28 is fixedly connected between the upper end of the loop 24 and the button 13, and between the lower end of the loop 24 and the button 13. A second locking block 25 is integrally formed at the end of the loop 24. The second locking block 25 is movably locked into the lace 23 of the outer ring 6.

[0052] In this embodiment, refer to the appendix. Figure 1 There is a gap between one of the inner rotating rings 5 ​​and the outer ring 6, through which the connecting rod 3 extends and rotates. Two turntables 4 are connected within the gap. The connecting rod 3 passes through the turntables 4. A bellows plate 30 is fixedly connected between the upper and lower ends of the two turntables 4. The bellows plate 30 can extend and retract, and moves within the gap between the inner rotating ring 5 and the outer ring 6.

[0053] In this embodiment, refer to the appendix. Figure 7 The locking assembly 26 includes a locking block 2601 and a third spring 2602. The locking block 2601 is movably inserted into the upper side of the base 8. The third spring 2602 is fixedly connected between the locking block 2601 and the base 8. The outer ring 6 is fixedly clamped between the locking block 2601 and the base 8.

[0054] The working principle of this device is as follows:

[0055] The patient lies down on the base 8, and medical staff simultaneously push the outer ring 6 forward, so that the patient's head rests on the soft cushion 7. The outer ring 6, inner rotating ring 5, and middle rotating ring 21 are then fitted over the patient's head, allowing for side-lying, flat-lying, or other reclining positions. Simultaneously pressing two buttons 13 compresses the second spring 18, disengaging the first locking block 22 from the lace 23 of the middle rotating ring 21 and the attached ring 20, and disengaging the second locking block 25 from the lace 23 of the outer ring 6. This allows the inner rotating ring 5 and the middle rotating ring 21 to rotate freely, and also allows for arbitrary adjustment of the headrest 11 angle. At the same angle as the breathing mask 1, press both buttons 13 downwards simultaneously, causing the first sliding sleeve 14, the second sliding sleeve 16, and the third sliding sleeve 19 to all move downwards. The third sliding sleeve 19 presses down on the elastic cord 2 to press the breathing mask 1 onto the patient's face. The tightness of the breathing mask 1 and the tightness and angle of the elastic cord 2 can be controlled according to the downward movement of the third sliding sleeve 19. At the same time, the second sliding sleeve 16 moves the connecting rod 3 downwards, and the connecting rod 3 moves the chin strap 12 downwards, placing the chin strap 12 on the patient's chin. (Refer to the appendix for details.) Figure 9 As can be seen, in order to ensure that the breathing mask 1 fits tightly to the patient's face, the lower end of the elastic rope 2 will be lower, while the chin strap 12 only needs to reach the height of the patient's chin, so that the lower end of the elastic rope 2 is lower than the height of the chin strap 12.

[0056] After wearing, release button 13 towards the center of outer ring 6, but still press button 13 vertically downwards so that button 13 does not move upwards, but moves towards the center of outer ring 6. The second spring 18 pushes button 13 back, so that the first locking block 22 is locked into the lace 23 of the middle rotating ring 21 and the attached ring 20, and the second locking block 25 is locked into the lace 23 of outer ring 6. This fixes the middle rotating ring 21, the attached ring 20 and the inner rotating ring 5 relative to the outer ring 6, and the drug inhalation can then begin.

[0057] When the patient's head makes small movements, the headrest 11, inner rotating ring 5, and middle rotating ring 21 all rotate, allowing the button 13 to rotate relative to the loop 24. Since the second locking block 25 is locked inside the lace 23 of the outer ring 6, the loop 24 does not move. Due to the limitation of the central angle of the loop 24 and the limitation of the fourth spring 28, the headrest 11, inner rotating ring 5, and middle rotating ring 21 can only rotate at a certain angle, rather than at any angle. That is, the patient's head is allowed to have some movements but not large movements, with a certain degree of tolerance within the restraint.

[0058] After the medication is inhaled, press button 13 and move button 13 upwards to move the elastic rope 2 upwards, and then remove the breathing mask 1 and chin strap 12.

[0059] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
