A sputum vest

Abstract

This utility model relates to a sputum-clearing vest, including an inflatable vest, a sputum-clearing mechanism, and a control unit. The inflatable vest is connected to an air pump in the control unit via a trachea. The sputum-clearing mechanism includes a base plate and several ultrasonic probes and vibration modules arranged in an array on the base plate. The ultrasonic probes and vibration modules are electrically connected to the control unit via wires. Several sputum-clearing mechanisms are detachably connected to the front chest, back, and two sides of the inflatable vest. This design uses a small-volume base plate as a carrier. The base plate is small and lightweight, allowing for more flexible conforming to the curves of the human body, such as the curved area of ​​the waist, reducing the pressure on the chest and abdomen caused by traditional large-size rigid plates. It is especially suitable for postoperative or weak patients, reducing discomfort during treatment. By eliminating large mounting plates, the weight of the vest worn by the patient is reduced, and moderate positional adjustments such as side-lying are allowed during treatment, overcoming the limitations on movement imposed by traditional rigid sputum-clearing vests.

Description

Technical Field

[0001] This utility model relates to the field of medical sputum drainage equipment technology, specifically to a sputum drainage vest. Background Technology

[0002] Airway clearance techniques refer to treatment methods that clear obstructed secretions from the airways and maintain airway patency through manual, pharmacological, or mechanical means. These include lung expansion techniques, airway vibration techniques, and other clearance techniques (including assisted coughing, internal airway suction, and postural drainage). Airway clearance techniques have now evolved into a comprehensive treatment system encompassing treatment methods, techniques, and equipment. Among these, mechanical airway clearance is one of the most widely used respiratory therapy and rehabilitation techniques in clinical practice.

[0003] Mechanical airway clearance refers to a treatment method that uses mechanical means to remove accumulated secretions from the airways and maintain airway patency. The human body has the ability to actively clear its airways under physiological conditions. However, when the airway barrier, mucus clearance system, and ability to cough are impaired due to disease or other factors, mechanical airway clearance can effectively remove airway secretions, prevent and reduce respiratory infections, and promote the rapid recovery of respiratory function in patients.

[0004] In clinical practice, airway percussion technology, also known as a sputum clearance machine, is commonly used for mechanically assisted sputum clearance. This technique improves pulmonary blood circulation and assists in the removal of respiratory secretions through vibration and percussion. Currently available sputum clearance machines only have vibration and percussion functions. Before operation, medical personnel need to conduct a comprehensive assessment using auscultation and imaging results to determine the appropriate patient position and percussion range. They cannot automatically identify lesion sites and provide precise treatment.

[0005] This solution addresses the aforementioned problem in a previously filed patent application for a sputum-clearing vest and its sputum-clearing control method (patent number 2024117163122). However, because it includes a front panel, a back panel, and two side panels that are spliced ​​together, see [link to patent application]. Figure 6 and Figure 7 Because the front, back, and two side panels are large and have a certain degree of rigidity, they are not easy to fit according to physiological curves. When worn by people of different body types, the vibration module and ultrasound detection module on the front, back, or two side panels may not fit well, resulting in poor sputum expectoration. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a sputum-expelling vest to overcome the shortcomings of the prior art.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a sputum-clearing vest, including an inflatable vest, a sputum-clearing mechanism and a control host; the inflatable vest is connected to the air pump in the control host through a trachea; the sputum-clearing mechanism includes a base plate, and several ultrasonic probes and vibration modules arranged in an array on the base plate, the ultrasonic probes and vibration modules being electrically connected to the control host through wires respectively; several sputum-clearing mechanisms are detachably connected to the front chest, back and two sides of the inflatable vest respectively.

[0008] The beneficial effects of this utility model are as follows: This solution modularizes the sputum clearance mechanism, using a small-volume substrate as the carrier. The substrate is small in size and light in weight, and can more flexibly conform to the curves of the human body, such as the curved area on the side of the waist, reducing the pressure on the chest and abdomen caused by traditional large-size rigid boards. It is especially suitable for postoperative or weak patients, reducing discomfort during treatment. Since the large-volume mounting plate is eliminated, the weight of the patient's clothing is reduced, and moderate positional adjustments such as side lying are allowed during treatment, breaking through the limitations of traditional rigid sputum clearance vests on movement.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a first Velcro strap is attached to the substrate, and a second Velcro strap covers the inside of the inflatable vest. The substrate is detachably connected to the inside of the inflatable vest via the first and second Velcro straps.

[0011] Furthermore, each of the four edges of the substrate is provided with a fastener, and the first Velcro is provided in four sets, which are detachably connected to the fasteners on the four edges of the substrate.

[0012] Furthermore, the substrate is arrayed with several mounting holes, and the vibration module and ultrasonic probe are detachably mounted in these mounting holes.

[0013] Furthermore, both the ultrasonic probe and the vibration module have positioning posts on their backs, and magnetic rings are fixedly fitted on the positioning posts. The positioning posts and the mounting holes are connected by magnetic attraction and plugging of the magnetic rings.

[0014] Furthermore, it also includes a pulse oximeter clip, which is electrically connected to the control unit via a wire.

[0015] Furthermore, the inflatable vest has adjustable straps on both sides of the chest.

[0016] Furthermore, a heating wire is provided inside the substrate, and the heating wire is electrically connected to the control host through a wire. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1 to 8 As shown in Embodiment 1, a sputum-clearing vest includes an inflatable vest 1, a sputum-clearing mechanism 2, and a control host 3. The inflatable vest 1 is connected to an air pump in the control host 3 via a trachea 4. The sputum-clearing mechanism 2 includes a base plate 21, and several ultrasonic probes 22 and vibration modules 23 arranged in an array on the base plate 21. The ultrasonic probes 22 and vibration modules 23 are electrically connected to the control host 3 via wires 5. Several sputum-clearing mechanisms 2 are detachably connected to the front chest, back, and two sides of the waist of the inflatable vest 1.

[0021] This solution modularizes the sputum clearance mechanism 2, using a small-volume base plate 21 as the carrier. The base plate 21 is small and lightweight, allowing for more flexible conformation to the curves of the human body, such as the curved area on the side of the waist. This reduces the pressure on the chest and abdomen caused by traditional large-sized rigid plates, making it especially suitable for postoperative or weak patients and reducing discomfort during treatment. By eliminating the large mounting plates, the weight of the garment worn by the patient is reduced, and moderate positional adjustments such as side-lying are allowed during treatment, breaking through the limitations of traditional rigid sputum clearance vests on movement.

[0022] After the patient puts on the inflatable vest 1, the air pump built into the control unit 3 inflates the inflatable vest 1, so that the ultrasound probe 22 and vibration module 23 fit the patient's body. Then, multiple ultrasound probes 22 are activated to detect different parts of the patient's lungs. When lung secretions are detected in the area where a certain ultrasound probe 22 is located, the vibration intensity of the corresponding vibration module 23 is adjusted, making the entire sputum expectoration process more precise and the sputum expectoration efficiency higher.

[0023] In practice, the ultrasound probes 22 on the two lumbar base plates 21 can detect pulmonary secretions while also monitoring the diaphragm's mobility and thickness, facilitating medical staff's assessment of the airway clearance treatment effect. The sputum clearance mechanism 2 is configured with 6, 8, or 10 groups. If it has 6 groups, one group is installed on the middle of the left and right sides of the front of the inflatable vest 1, one group is installed on the middle of the left and right lumbar sides of the inflatable vest 1, and one group is installed on the middle of the left and right sides of the back of the inflatable vest 1. If it has 8 groups, one group is installed on the front of the inflatable vest 1... Two sets are set on each side of the chest; if there are 10 sets, two sets are also set on the middle of each side of the back of the inflatable vest 1. In addition, the air pipe 4 includes an air inlet pipe and an air outlet pipe. The two ends of the air inlet pipe are connected to the air pump in the inflatable vest 1 and the control host 3, respectively. The two ends of the air outlet pipe are connected to the solenoid valve or other conventional electrically controlled valve in the inflatable vest 1 and the control host 3, respectively. A one-way valve that allows air to enter is set at the air inlet end of the inflatable vest 1 or the air outlet end of the air inlet pipe. When the inflatable vest 1 is inflated, the solenoid valve is closed.

[0024] Example 2 is a further improvement based on Example 1, and its details are as follows: A first Velcro 24 is attached to the substrate 21, and a second Velcro 11 covers the inside of the inflatable vest 1. The substrate 21 is detachably connected to the inside of the inflatable vest 1 via the first Velcro 24 and the second Velcro 11. This arrangement allows the substrate 21 to be adaptively adjusted in position within the coverage area of ​​the second Velcro 11. In a specific implementation, the first Velcro 24 and the second Velcro 11 are male and female, respectively.

[0025] Example 3 is a further improvement based on Example 2, and its details are as follows: Each of the four edges of the substrate 21 is provided with a retaining ring 211. Four sets of first hook and loop fasteners 24 are provided, each detachably connected to one of the retaining rings 211 on the four edges of the substrate 21. In a specific implementation, the second hook and loop fastener 11 uses a new type of hookless hook and loop fastener. The rough surface of the first hook and loop fastener 24 may become unstable during long-term use. The retaining rings 211 allow the first hook and loop fastener 24 to be disassembled and replaced as needed.

[0026] Example 4 is a further improvement based on Example 1, and its details are as follows: The substrate 21 has an array of mounting holes 212, and the vibration module 23 and the ultrasound probe 22 are detachably mounted in the mounting holes 212. This allows for adaptive and precise adjustment of the vibration module 23 and the ultrasound probe 22 according to the patient's body size and lung position.

[0027] Example 5 is a further improvement on Example 4, and its details are as follows: Both the ultrasonic probe 22 and the vibration module 23 have positioning posts 2231 on their backs. A magnetic ring 2232 is fixedly sleeved on the positioning post 2231, and the positioning post 2231 is magnetically connected to the mounting hole 212 via the magnetic ring 2232. This allows for more convenient and faster adjustment and fixation of the ultrasonic probe 22 and the vibration module 23 according to actual needs.

[0028] Example 6 is a further improvement based on Example 1, and its details are as follows: It also includes a pulse oximeter clip, which is electrically connected to the control host 3 via wire 5. The pulse oximeter clip can monitor the patient's blood oxygen parameters in real time, and can promptly shut down the vibration module 23 when abnormal blood oxygen parameters occur during sputum expectoration.

[0029] Example 7 is a further improvement based on any one of Examples 1 to 6, and its details are as follows: The inflatable vest 1 has adjustable straps 12 on both sides of the chest for easy adjustment to suit different body types.

[0030] Example 8 is a further improvement based on any one of Examples 1 to 7, and its details are as follows: A heating wire is installed inside the substrate 21, and the heating wire is electrically connected to the control host 3 through the wire 5. The heating wire can heat the substrate 21, and the heating promotes the patient's blood circulation, which can not only help with sputum expectoration, but also make the patient more comfortable wearing the sputum expectoration vest.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
