Description

Technical Field

[0001] The invention relates to the technical field of medical expectoration equipment, and in particular to an expectoration vest and an expectoration control method thereof. Background Art

[0002] Airway clearance technology refers to a treatment method that clears airway secretions and maintains airway patency through artificial, drug or mechanical methods. It includes lung inflation technology, airway shock technology, assisted cough technology, airway suction and postural drainage. Airway clearance technology has now developed into a treatment system that includes treatment methods, technical means and application equipment. Among them, mechanical airway clearance technology is one of the most widely used respiratory treatment and respiratory rehabilitation medical technologies in clinical frontline.

[0003] Mechanical airway clearance technology refers to a treatment method that mechanically removes airway secretions and maintains airway patency. The human body has the ability to actively clear the airway under physiological conditions. However, when the airway barrier, mucus clearance system and active coughing ability of the human body are damaged due to various factors such as disease, mechanical airway clearance technology can effectively clear airway secretions, prevent and reduce respiratory infections, and promote the patient's respiratory function to recover as soon as possible.

[0004] In clinical practice, airway vibration technology, namely, expectoration machines, are often used for mechanical assisted expectoration. Vibration percussion is used to improve the patient's pulmonary blood circulation and assist in the removal of respiratory secretions. Currently, expectoration machines on the market only have vibration percussion functions. Before the operation is performed, medical staff need to conduct a comprehensive assessment through auscultation combined with imaging results to determine the position of the operation and the range of percussion. They cannot automatically identify the site of the lesion and provide precise treatment. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a sputum discharge vest and a sputum discharge control method thereof to overcome the deficiencies in the above-mentioned prior art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a sputum discharge vest, comprising a vest body, a sputum discharge mechanism and a control host; the inner side of the vest body is covered with a plurality of interconnected air bags, one of which is connected to an inflation interface, and the inflation interface is externally connected to an inflation device; the sputum discharge mechanism comprises a detachably connected front plate, a rear plate and two side plates respectively connected to the front plate and the rear plate on both sides, a plurality of ultrasonic probes are respectively arranged in an array on the inner sides of the front plate and the two side plates, a plurality of vibration modules are respectively arranged in an array on the inner sides of the front plate, the rear plate and the two side plates, and the ultrasonic probes and the vibration modules are respectively electrically connected to the control host through wires.

[0007] The beneficial effect of the present invention is that after the patient puts on the vest body, the airbag is inflated by the inflation device, so that the ultrasonic probe and the vibration module fit the patient's body, and then multiple ultrasonic probes are started to detect different parts of the patient's lungs respectively. When lung secretions are detected in the area where a certain ultrasonic probe is located, the vibration intensity of the vibration module in the corresponding area is adjusted, so that the vibration expectoration treatment is more precise and the expectoration efficiency is higher.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a plurality of mounting holes are arranged in an array on the front plate, the rear plate and the two side plates, and the vibration module and the ultrasonic probe are detachably arranged in the plurality of mounting holes.

[0010] Furthermore, a positioning column is provided on the back of the ultrasonic probe and the vibration module, a magnetic ring is fixed on the positioning column, and the positioning column is connected to the mounting hole by magnetic attraction and plugging of the magnetic ring.

[0011] Furthermore, it also includes a blood oxygen clamp, which is electrically connected to the control host through a wire.

[0012] Furthermore, a pickup is arranged above the front plate, and the pickup is electrically connected to the control host.

[0013] Furthermore, heating wires are provided in the front plate and the rear plate, and the heating wires are electrically connected to the control host.

[0014] The present invention also discloses a method for controlling sputum discharge of a sputum discharge vest, which is applied to the above-mentioned sputum discharge vest and comprises the following steps:

[0015] Step S01: activating the expectoration vest, inflating the airbag through an external inflation device, making the ultrasound probe and the vibration module fit the patient's body, activating all ultrasound probes, and examining the patient's lungs;

[0016] Step S02: When pulmonary secretions are detected in a certain area, the control host will start all vibration modules in sequence at the basic vibration frequency according to the preset program, and then increase the vibration intensity of the vibration modules corresponding to each area according to the degree of exudation of pulmonary secretions in different areas;

[0017] Step S03: The ultrasonic probe checks and determines the exudation degree of the pulmonary secretions in each area of ​​the lung in real time, and compares the current exudation degree with the previous exudation degree. If the exudation degree is reduced, the vibration intensity of the vibration module corresponding to the area is reduced; if the exudation degree is increased, the vibration intensity of the vibration module corresponding to the area is increased; if the exudation degree of the area is no, the vibration module corresponding to the area is adjusted to the basic vibration frequency;

[0018] Step S04: When all the ultrasound probes fail to detect pulmonary secretions, all the vibration modules and ultrasound probes are turned off, and the gas in the air bag is exhausted.

[0019] The beneficial effects of the present invention are as follows: the expectoration control method can automatically perform vibration expectoration according to the detection results of the ultrasonic probe, and the expectoration process does not require human intervention, thereby improving the therapeutic efficiency of expectoration and enhancing the effect of expectoration treatment.

[0020] Based on the above technical solution, the present invention can also be improved as follows.

[0021] Further, step S03 also includes starting the microphone to detect in real time whether the patient has a continuous cough. When it is detected that the patient has a continuous cough, the control host sends an instruction to stop the vibration module, otherwise the microphone continues to maintain continuous cough detection.

[0022] Further, step S03 also includes starting the blood oxygen clamp to detect in real time whether the patient's blood oxygen saturation is abnormal. When it is detected that the patient's blood oxygen saturation is abnormal, the control host sends an instruction to stop the vibration module, otherwise the blood oxygen clamp continues to maintain blood oxygen detection.

[0023] Further, step S02 also includes: controlling the host to record the location of the secretions in the lungs detected by the ultrasound probe in a built-in memory, generating a vibration sequence of several vibration modules according to the location of the secretions in the lungs, so that the vibration modules at the location of the secretions in the lungs vibrate from outside to inside and from bottom to top in turn.

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] like Figure 1 to Figure 5 As shown, Example 1, a sputum discharge vest, includes a vest body 1, a sputum discharge mechanism 2 and a control host; the inner side of the vest body 1 is covered with a plurality of interconnected airbags 101, one of the airbags 101 is connected to an inflation interface 102, and the inflation interface 102 is externally connected to an inflation device; the sputum discharge mechanism 2 includes a detachably connected front plate 201, a rear plate 202 and two side plates 203 respectively connected to the front plate 201 and the rear plate 202 on both sides, a plurality of ultrasonic probes 204 are respectively arranged in an array on the inner sides of the front plate 201 and the two side plates 203, a plurality of vibration modules 205 are respectively arranged in an array on the inner sides of the front plate 201, the rear plate 202 and the two side plates 203, and the ultrasonic probes 204 and the vibration modules 205 are respectively electrically connected to the control host through wires.

[0034] After the patient puts on the vest body 1, the airbag 101 is inflated through the inflation device to make the ultrasonic probe 204 and the vibration module 205 fit the patient's body, and then multiple ultrasonic probes 204 are started to detect different parts of the patient's lungs respectively. When the area where a certain ultrasonic probe 204 is located detects pulmonary secretions, the vibration intensity of the vibration module 205 in the corresponding area is adjusted, so that the entire expectoration process is more precise and the expectoration efficiency is higher.

[0035] The ultrasound probes 204 on the two side panels 203 can monitor the activity and thickness of the diaphragm while detecting secretions in the lungs, so that medical staff can evaluate the therapeutic effect of airway clearance.

[0036] In a specific implementation, two adjacent front panels 201, rear panel 202 and two side panels 203 are detachably connected by Velcro, and the ultrasonic probes 204 are arranged in 4 groups, 6 groups or 8 groups. If there are 4 groups, one group is arranged in the middle of the left and right sides of the front panel 201, and one group is arranged in the middle of the two side panels 203; if there are 6 groups, one group is arranged in the upper and lower parts of the left and right sides of the front panel 201, and one group is arranged in the middle of the two side panels 203; if there are 8 groups, one group is arranged in the upper and lower parts of the front panel 201, and one group is arranged in the upper and lower parts of the two side panels 203.

[0037] In addition, the front chest of the vest body 1 is fastened and adjusted by the buckle 103, which is conducive to adjusting the tightness according to patients of different body shapes; the vibration module 205 and the ultrasonic probe 204 are integrated. In specific implementation, part of the vibration module 205 can be combined with the ultrasonic probe 204 to reduce the number of ultrasonic probes 204, thereby reducing costs.

[0038] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0039] A plurality of mounting holes 206 are arranged in an array on the front plate 201, the rear plate 202 and the two side plates 203, and the vibration module 205 and the ultrasonic probe 204 are detachably arranged in the plurality of mounting holes 206. This facilitates adaptive and precise adjustment of the vibration module 205 and the ultrasonic probe 204 according to the patient's body shape and lung position. In a specific implementation, a wire channel is provided between adjacent mounting holes 206, and the wires of the ultrasonic probe 204 and the vibration module 205 are movably arranged in the wire channel.

[0040] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 2, and its details are as follows:

[0041] The back of the ultrasonic probe 204 and the vibration module 205 are both provided with a positioning column 207, a magnetic ring 208 is fixedly sleeved on the positioning column 207, and the positioning column 207 is connected to the mounting hole 206 by magnetic attraction and plugging through the magnetic ring 208. This allows the position of the ultrasonic probe 204 and the vibration module 205 to be adjusted and fixed more conveniently and quickly according to actual needs.

[0042] Embodiment 4: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0043] The device also includes a blood oxygen clamp which is electrically connected to the control host through a wire. The blood oxygen clamp can monitor the patient's blood oxygen parameters in real time, and when abnormal blood oxygen parameters occur during expectoration, the vibration module 205 can be turned off in time.

[0044] Embodiment 5, this embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0045] A microphone 209 is provided above the front panel 201 and is electrically connected to the control host. The microphone 209 can pick up sound in real time, so that the control host can monitor whether the patient has a continuous cough. If so, it indicates that the patient can cough voluntarily, and the vibration module 205 can be turned off to temporarily stop the sputum discharge treatment.

[0046] Embodiment 6: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0047] The front plate 201 and the rear plate 202 are both provided with heating wires 210, and the heating wires 211 are electrically connected to the control host. The heating wires 210 can heat the front plate 201, the rear plate 202 and the two side plates 203, and promote the patient's blood circulation by heating, which can not only play a role in assisting sputum discharge, but also make the patient more comfortable wearing the sputum discharge vest.

[0048] like Figure 6 As shown, in Example 7, a method for controlling sputum discharge of a sputum discharge vest is applied to the sputum discharge vest of any one of Examples 1 to 6, comprising the following steps:

[0049] Step S01: Start the expectoration vest, inflate the airbag 101 through an external inflation device, make the ultrasonic probe 204 and the vibration module 205 fit the patient's body, start all the ultrasonic probes 204, and examine the patient's lungs;

[0050] Step S02: When pulmonary secretions are detected in a certain area, the control host will start all vibration modules 205 in sequence at the basic vibration frequency according to the preset program, and then increase the vibration intensity of the vibration modules 205 corresponding to each area according to the degree of exudation of pulmonary secretions in different areas;

[0051] Step S03: The ultrasonic probe 204 checks and determines the exudation degree of the pulmonary secretions in each area of ​​the lung in real time, and compares the current exudation degree with the previous exudation degree. If the exudation degree is reduced, the vibration intensity of the vibration module 205 corresponding to the area is reduced (i.e., the gear is reduced); if the exudation degree is increased, the vibration intensity of the vibration module 205 corresponding to the area is increased (i.e., the gear is increased); if the exudation degree of the area is no, the vibration module 205 corresponding to the area is adjusted to the basic vibration frequency;

[0052] Step S04 : when all the ultrasonic probes 204 do not detect any secretions in the lungs, all the vibration modules 205 and the ultrasonic probes 204 are turned off, and the gas in the air bag 101 is exhausted.

[0053] The expectoration control method can automatically perform vibration expectoration according to the detection result of the ultrasonic probe 204, and the expectoration process does not require human intervention, thereby improving the efficiency of expectoration treatment and enhancing the effect of expectoration treatment.

[0054] Embodiment 8, this embodiment is a further improvement on the basis of embodiment 7, and its details are as follows:

[0055] Step S03 also includes starting the microphone 209 to detect in real time whether the patient has a continuous cough. When it is detected that the patient has a continuous cough, the control host sends an instruction to stop the vibration module 205, otherwise the microphone 209 continues to maintain the continuous cough detection. The microphone 209 performs real-time sound pickup, so that the control host can monitor whether the patient has a continuous cough. If so, it indicates that the patient can expectorate by coughing autonomously, and the vibration module 205 can be turned off to temporarily stop the expectoration treatment.

[0056] Embodiment 9: This embodiment is a further improvement on the basis of embodiment 7, and its details are as follows:

[0057] Step S03 also includes starting the blood oxygen clamp to detect in real time whether the patient's blood oxygen saturation is abnormal. When the patient's blood oxygen saturation is detected to be abnormal, the control host sends an instruction to stop the vibration module 205, otherwise the blood oxygen clamp continues to maintain blood oxygen detection. The blood oxygen parameters of the patient are monitored in real time by the blood oxygen clamp. When the blood oxygen parameters are abnormal during the expectoration process, the vibration module 205 is automatically turned off.

[0058] Embodiment 10: This embodiment is a further improvement on the basis of embodiment 7, and its details are as follows:

[0059] Step S02 also includes: controlling the host to record the location of the pulmonary secretions detected by the ultrasonic probe 204 in the built-in memory, generating a vibration sequence of several vibration modules 205 according to the location of the pulmonary secretions, and making the vibration modules 205 at the location of the pulmonary secretions vibrate from outside to inside and from bottom to top in sequence. Since the pulmonary secretions are distributed in different parts of the lungs, the vibration modules 205 vibrate from outside to inside and from bottom to top in sequence according to the lung contour and the direction of the bronchus (bronchiole-bronchus-trachea), that is, the vibration module 205 located at the edge of the lung contour vibrates first, so that the pulmonary secretions gather from the edge of the lung to the middle, and then move toward the bronchus, which is conducive to the discharge of the pulmonary secretions.

[0060] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
