Description

Technical Field

[0001] This utility model relates to the field of mattresses, specifically to a pneumatically assisted patting mattress. Background Technology

[0002] In various pathological conditions, patients' ability to expel sputum spontaneously decreases significantly, leading to the accumulation of sputum in the respiratory tract. This can not only obstruct the airway and cause breathing difficulties, but may even be life-threatening when the patient is bedridden. Therefore, developing a device that can effectively assist patients in expelling sputum while lying down is of significant clinical importance. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatically assisted percussion mattress that integrates a multi-module pneumatic percussion system. It aims to simulate the percussion technique used in physical therapy to effectively promote the loosening and expulsion of sputum, while reducing the frequency of coughing caused by sputum irritation.

[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0005] A pneumatically assisted tapping mattress includes: a mattress body; a pneumatic tapping layer disposed within the mattress body, the pneumatic tapping layer including at least one tapping module, the tapping module comprising multiple inflatable and deflated tapping airbags; a pneumatic system including an air pump connected to the tapping airbags and a solenoid valve for controlling the air path, the pneumatic system being used to provide a pulsed air source to the tapping airbags to generate tapping action; and a controller for controlling the operation of the pneumatic system to drive the tapping airbags to apply a preset rhythmic tapping motion to the user's back.

[0006] Furthermore, the tapping module includes tapping airbags arranged in a matrix, and the tapping module is laid out according to the regions on both sides of the thoracic and lumbar vertebrae on the back of the human body.

[0007] Furthermore, the patting airbag is shaped like a disc with a concave central area, so that when it is inflated, the edge portion preferentially contacts the user's back.

[0008] Furthermore, the inside of the slapping airbag is provided with a pull strap connecting its upper and lower inner walls. The length of the pull strap near the center of the slapping airbag is shorter than the length of the pull strap near its edge, thereby forming a structure inwardly concave in the center when inflated.

[0009] Furthermore, it also includes a human-computer interaction module and at least one thin-film pressure sensor disposed on the mattress body for detecting the contact pressure distribution between the user's back and the mattress. The controller is electrically connected to the pressure sensor and the human-computer interaction module. When an improper user posture is detected, the controller instructs the human-computer interaction module to issue an audio-visual prompt.

[0010] Furthermore, the thin-film pressure sensor is disposed in the central recessed area of ​​the slapping airbag.

[0011] Furthermore, the solenoid valve is a three-way solenoid valve. The controller selectively establishes a "pump-blow airbag" path for rapid inflation or a "blow airbag-atmosphere" path for rapid deflation by controlling the three-way solenoid valve.

[0012] Furthermore, the mattress body comprises, from top to bottom, a surface layer, a pneumatic tapping layer, a support layer, an integrated pipeline layer, and a bottom layer.

[0013] Furthermore, the integrated piping layer is used to house pneumatic hoses and lines, and has guide grooves and / or fixing clips inside for fixing and guiding the piping.

[0014] Furthermore, the surface layer is removable.

[0015] Compared with the prior art, this application has the following advantages:

[0016] The embodiments of this utility model can rhythmically pat the patient's back, achieving multiple effects such as massage and phlegm removal. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 (Overall structure diagram) The mattress structure from top to bottom consists of: surface layer 1, pneumatic pounding layer 2, support layer 3, integrated pipeline layer 4 and bottom layer 5. Its core power system consists of an air pump 6 and a set of solenoid valves 7.

[0025] refer to Figure 1 and Figure 2 ( Figure 2 A patting module 21 is shown, each patting module 21 includes four patting airbags 22), and the pneumatic patting layer 2 is laid out according to the main areas of the human back (both sides of the thoracic and lumbar vertebrae), consisting of multiple sets of independently controllable patting modules 21. Each set of patting modules 21 consists of multiple patting airbags 22 arranged in a matrix to ensure that it can adapt to different body shapes and back curves.

[0026] The air pump 6 is connected to each patting airbag 22 via a solenoid valve 7 and a hose, which precisely controls its inflation and deflation to achieve rhythmic patting.

[0027] The solenoid valve 7 is designed as a three-way solenoid valve to precisely switch the air path, thereby selectively establishing the "air pump 6 - patting airbag 22" path (rapid inflation) or the "patting airbag 22 - atmosphere" path (rapid deflation), providing a basis for realizing high-frequency pulse patting.

[0028] Top layer 1 is made of medical-grade fabric, which is breathable, skin-friendly, antibacterial, waterproof, and easy to clean, ensuring hygiene and comfort for patients. Top layer 1 is designed to be removable for easy regular cleaning and disinfection.

[0029] Support layer 3 uses high-density medical-grade sponge or memory foam, combined with an independent pocket spring system. This design not only provides stable and comfortable basic support but also effectively distributes body pressure, playing a positive role in preventing pressure sores. Figure 1 The patting module 21 shown is embedded in the top of the support layer 3, and the surface 1 of the patting module 21 is flush with the surface 1 of the support layer 3.

[0030] The integrated piping layer 4 is located between the support layer 3 and the bottom layer 5. It is used to neatly and safely store all pneumatic hoses and sensor lines. It has prefabricated guide grooves and fixing buckles inside, which can effectively prevent the pipes from getting tangled or compressed, and simplify the subsequent maintenance and repair process.

[0031] The bottom layer 5 uses high-strength coconut fiber material to provide a stable foundation for the upper structure.

[0032] Furthermore, to simulate the efficiency and comfort of a physical therapist's "hollow palm" tapping technique, reference was made to... Figure 3 (3D view of the shock-absorbing airbag 22) The shock-absorbing airbag 22 is designed as a disc with a concave center.

[0033] When the airbag is rapidly inflated by a pulsed airflow, its edges expand first and contact the patient's back, while the central concave area instantly forms a sealed vibration chamber. This design can generate a shock wave-like effect, effectively loosening deep sputum, while avoiding the blunt pressure caused by traditional flat-plate percussion, significantly improving treatment effectiveness and patient comfort.

[0034] The principle behind this is that the airbag has several straps (or wires) connecting its upper and lower surfaces. By precisely designing the length of the straps so that the straps in the central area are shorter than those in the edge areas, the center point of the airbag is pulled inward when it is inflated, naturally forming a controllable concave shape.

[0035] Furthermore, the mattress is embedded with multiple thin-film pressure sensors 8 to monitor the contact pressure distribution between the patient's back and the mattress in real time. If the system detects that the patient's posture is incorrect (such as positional deviation or back not fully conforming), the controller will instruct the human-machine interaction module to guide the patient to adjust to the correct position through audio-visual prompts (such as flashing indicator lights and voice reminders), thereby ensuring the optimal therapeutic effect of the tapping function.

[0036] Preferred solution: The human-computer interaction module integrates voice recognition functionality, allowing users to operate the system using simple voice commands (such as "start" and "stop").

[0037] Preferred solution: To extend the life of the sensor and ensure measurement accuracy, the thin-film pressure sensor 8 is arranged in the central recess of the slapping airbag 22. This arrangement ensures that during the pulse slapping process, the high pressure mainly acts on the edge of the airbag, while the sensor is located in the low-pressure area, effectively avoiding direct mechanical impact and ensuring its long-term stability and reliability.

[0038] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of this utility model.
