Description

Technical Field

[0001] This utility model relates to a wearable sputum-assisted expectoration device. Background Technology

[0002] Respiratory diseases are a major public health problem with high morbidity and mortality rates worldwide, and prevention and control efforts face considerable challenges. Among these challenges, hypostatic pneumonia caused by the accumulation of airway secretions in long-term bedridden patients is a key issue requiring close attention in clinical nursing.

[0003] Related studies show that the incidence of hypostatic pneumonia is high among elderly patients who are bedridden for a long time, and the proper use of back percussion and sputum drainage equipment can reduce the mortality rate of such patients, which demonstrates the important value of efficient sputum drainage methods in improving patient prognosis.

[0004] Currently, commonly used clinical methods for assisted sputum clearance involve manually and regularly tapping the patient's back to loosen the sputum, combined with inhaled nebulized medication to reduce sputum concentration and promote expectoration. However, this method relies heavily on manual operation, which is inconvenient in practice and requires a high level of experience and skill from medical staff. While existing electric vibration sputum clearance devices can replace some manual operations and improve sputum clearance efficiency to a certain extent, they are bulky, difficult to move, and require specific patient positioning, making them difficult to flexibly adapt to different patient care scenarios. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a compact and portable wearable sputum-assisted expectoration device that can improve the expectoration effect.

[0006] This utility model relates to a wearable assisted sputum expectoration device, comprising a vibration and tapping mechanism, a drug nebulization inhalation mechanism, and a vest. The vest includes a main body worn on the back and straps that hold the main body in place on the patient's back. The vibration and tapping mechanism includes multiple vibration and tapping modules disposed on the main body of the vest, which are evenly spaced along the transverse and longitudinal directions of the main body. The drug nebulization inhalation mechanism is connected to the straps and is positioned in front of the patient's chest when worn. The drug nebulization inhalation mechanism includes a drug storage bottle for storing medication and an airflow generation module connected to the drug storage bottle.

[0007] When in use, the main body of the vest is fixed to the patient's back with straps. The vibrations generated by multiple vibration and tapping modules can act on the patient's back, which helps to loosen the sputum in the patient's abdomen. Since multiple vibration and tapping modules are arranged in the longitudinal and transverse directions, the coverage area is wide and has a better fit for people of different body types, and can cover the area where the sputum is located. In addition, the medicine nebulizer located in front of the chest allows the patient to inhale medicine that can reduce the concentration of sputum, and together with the tapping of relevant parts of the back by multiple vibration and tapping modules, it can promote the expulsion of sputum and improve the expectoration effect.

[0008] Furthermore, the strap includes two shoulder straps and two chest straps. One end of each shoulder strap is connected to the upper part of the main body, and one end of each chest strap is connected to the upper sides of the main body. The other ends of the two chest straps are connected together in a tightening manner. The other ends of the two shoulder straps are also connected to the chest straps in a tightening manner. This allows for convenient and reliable wearing, ensuring that the main body fits snugly against the patient's back. The medication atomizing inhalation mechanism is connected to the chest strap or shoulder strap, making it convenient for medical staff or patients to operate. It also helps to balance the center of gravity from front to back, improving wearing comfort.

[0009] Furthermore, the other ends of the two chest straps are connected by Velcro, and the other ends of the two shoulder straps are connected to the two chest straps by Velcro, which can be tightened as needed, thus improving the fit for people of different body types.

[0010] Furthermore, the liquid medication atomization inhalation mechanism includes a housing fixed to the strap and a mask. An airflow generation module is installed inside the housing and is connected to the liquid medication storage bottle and the mask in sequence through a pipeline. The airflow generation module can generate airflow, which enters the liquid medication storage bottle through the pipeline and atomizes the liquid medication stored inside. The atomized liquid medication can be inhaled by the patient through the mask.

[0011] Furthermore, the main body of the vest includes a fabric layer on the front side and a rigid layer on the back side of the fabric layer. The vibration and impact module includes a housing embedded and fixed on the main body, a contact on the front side of the main body, a push rod that is movably inserted between the main body and the housing and connected to the rear end of the contact, and a movable iron core movably disposed in the housing. The housing also includes a coil winding that forms an electromagnetic drive with the movable iron core, and first and second springs respectively used to drive the push rod and the movable iron core to reset.

[0012] When the coil winding is energized, it generates magnetic force, causing the movable iron core to move forward. As the movable iron core moves forward, it strikes the rear end of the push rod, producing a slapping effect on the patient's back. After the coil winding is de-energized, the first and second springs drive the push rod and the movable iron core to return to their original position. Continuous slapping action can be achieved through the cyclic control of energizing and de-energizing. In addition, by increasing the energizing and de-energizing frequency of the coil winding, a higher frequency reciprocating motion of the movable iron core can be achieved, causing the center of gravity of the vibration and slapping module to constantly change to achieve a vibration effect. The front end of the movable iron core can also enhance the vibration effect by moderately impacting the rear end of the push rod.

[0013] Furthermore, the vibration and tapping modules distributed longitudinally are triggered one by one in a bottom-up order to generate tapping actions, which can help sputum to be expelled from the throat from bottom to top.

[0014] This utility model is small in size and easy to carry. It can be worn on the patient like a vest, with low requirements on the patient's body position and a wide range of applications. It is especially convenient for bedridden patients who have difficulty moving. Attached Figure Description

Detailed Implementation

[0016] Embodiments of the wearable sputum-clearing device of this utility model, such as Figure 1-4 As shown, the device includes a vibration and tapping mechanism, a drug nebulization inhalation mechanism, and a vest. The vest includes a main body 11 worn on the back and straps that hold the main body 11 to the patient's back. The vibration and tapping mechanism includes multiple vibration and tapping modules 2 disposed on the main body 11 of the vest. The multiple vibration and tapping modules 2 are arranged at uniform intervals along the transverse and longitudinal directions of the main body 11 (e.g., ...). Figure 2 , Figure 3 As shown), the liquid medication atomizing inhalation mechanism is connected to the strap and is positioned in front of the patient's chest when worn (e.g., Figure 1 As shown, the liquid atomization inhalation mechanism includes a liquid storage bottle 53 for storing liquid medicine and an airflow generation module connected to the liquid storage bottle 53.

[0017] The strap includes two shoulder straps 31 and two chest straps 32. One end of each shoulder strap 31 is connected to the upper end of the main body 11, with a gap between them. One end of each chest strap 32 is connected to the upper sides of the main body 11, and the other ends of the chest straps 32 are fastened together with Velcro. The other ends of each shoulder strap 31 are fastened together with the two chest straps 32 with Velcro. This allows for convenient and reliable wearing, and the straps can be tightened as needed, improving adaptability to different body types and ensuring that the main body 11 fits snugly against the patient's back. The medication atomizing inhalation mechanism is connected to the chest straps 32 or shoulder straps 31, facilitating operation by medical personnel or patients and improving front-to-back balance and wearing comfort.

[0018] In this embodiment, the shoulder straps 31 and chest straps 32 are made of elastic fabric with a napped surface. Figure 3 In the view shown, the front side of the left chest strap 32 is provided with a barbed surface 4, which is used to cooperate and adhere to the rear side of the right chest strap 32. The upper rear side of the two shoulder straps 31 is provided with barbed surfaces, which are respectively cooperated and adhered to the front side of the two chest straps 32.

[0019] The main body 11 of the vest includes fabric layers 111 on the front and back sides, and a rigid layer 112 between the two fabric layers 111. The fabric layers 111 are preferably made of a skin-friendly material, and the rigid layer 112 is made of plastic. The rigid layer 112 helps maintain the structural stability of the main body 11, thereby better ensuring that the vibration and striking modules 2 are pressed firmly against the patient's back. When unfolded, the main body 11, shoulder straps 31, and chest strap 32 resemble the shape of a "manta ray" (e.g., ...). Figure 3 (As shown).

[0020] like Figure 4 As shown, the vibration and striking module 2 includes a housing 21 embedded and fixed on the main body 11, a contact 22 disposed on the front side of the main body 11, a push rod 23 movably passing between the main body 11 and the housing 21 and connected to the rear end of the contact 22, a movable iron core 24 movably disposed within the housing 21, and a coil winding 25 disposed within the housing 21 to form an electromagnetic drive cooperation with the movable iron core 24, a first spring 26 and a second spring 27 respectively used to drive the push rod 23 and the movable iron core 24 to reset. Spring 27, wherein the contact 22 has a flat structure and is made of skin-friendly silicone material. The front end of the contact 22 has an arc-shaped surface, so that there is no abrupt feeling when it comes into contact with the skin. The rear end of the contact 22 is connected to the front end of the push rod 23. The rear end of the push rod 23 has an abutment part that abuts against the first spring 26. This abutment part is also used to withstand the impact of the movable iron core 24. The second spring 27 abuts against the front edge of the movable iron core 24. After the push rod 23 and the movable iron core 24 are reset, there is a certain distance between them.

[0021] When the coil winding 25 is energized, it generates magnetic force, causing the movable iron core 24 to move forward. As the movable iron core 24 moves forward, it strikes the rear end of the push rod 23, producing a slapping effect on the patient's back. After the coil winding 25 is de-energized, the first and second springs drive the push rod 23 and the movable iron core 24 to return to their original position. Continuous slapping action can be achieved through the cyclic control of energizing and de-energizing. In addition, by increasing the energizing and de-energizing frequency of the coil winding 25, the movable iron core 24 can achieve a higher frequency of reciprocating motion, causing the center of gravity of the vibration and slapping module 2 to constantly change to achieve a vibration effect. The front end of the movable iron core 24 can also enhance the vibration effect by moderately impacting the rear end of the push rod 23.

[0022] By connecting to the controller and combining it with a simple and universal programming, it is possible to achieve the following: the vibration and tapping modules 2 distributed along the longitudinal direction are triggered one by one in order from bottom to top to generate tapping action, which can produce a wave-like surging effect, making it easier to help phlegm be expelled from the throat from bottom to top.

[0023] The medication atomization inhalation mechanism includes a housing 51 fixed to the straps and a mask 52. An airflow generation module is disposed inside the housing 51 and connected to the medication storage bottle 53 and the mask 52 sequentially via tubing. The airflow generation module generates airflow, which enters the medication storage bottle 53 through the tubing and atomizes the stored medication. The atomized medication is then inhaled by the patient through the mask 52. The airflow generation module includes an air pump. In addition to the airflow generation module, the housing 51 can also house a power module, powered by an external power supply or a built-in battery. The power module can power the airflow generation module and also the vibration and tapping module 2. The housing 51 can also accommodate the controller. The power cord for powering the vibration and tapping module 2 can be arranged along the surface or inside the main body 11 and the shoulder strap 31 / chest strap 32.

[0024] In use, the main body 11 of the vest is fixed to the patient's back with straps, and the mask 52 is worn on the face. The vibration and tapping mechanism starts working first, generating vibration. The vibration acts on the patient's back, loosening the sputum in the patient's abdomen. In conjunction with the nebulized medication inhalation mechanism, the patient inhales nebulized medication to reduce the concentration of sputum. After the nebulized inhalation is completed, the mask is removed, and multiple vibration and tapping modules 2 tap the relevant parts of the back to promote sputum discharge and improve the expectoration effect.

[0025] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
