Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a lung clearing and expectoration device for respiratory nursing. Background Art

[0002] The lung clearing and expectoration device is a medical device used to assist in the treatment of respiratory diseases, especially patients with chronic obstructive pulmonary disease, bronchitis, etc. It can effectively reduce respiratory obstruction, promote airway patency, and relieve patients' breathing difficulties. The effect of lung clearing and expectoration is through improving lung function, etc.

[0003] In actual applications, existing motor-driven suction devices generally have the problem of not being able to work synchronously with the patient's natural breathing frequency. The natural breathing frequency of the human body changes significantly with different respiratory cycles, especially during inhalation and exhalation, when the pressure and flow rate of the airflow will be different. Traditional suction devices cannot sense the patient's breathing rhythm in real time, and usually work in a fixed suction mode, causing the patient to still be disturbed by the suction effect when inhaling, resulting in shortness of breath or discomfort. Especially for those patients who need to precisely control the intensity of suction, this fixed mode not only affects the patient's comfort, but may also cause excessive stimulation of the respiratory tract, increase the risk of dyspnea, and even cause severe respiratory damage or induce aspiration pneumonia. A suction device that is not synchronized with breathing cannot effectively alleviate the patient's symptoms, but may aggravate shortness of breath and affect the recovery effect.

[0011] The beneficial effects of the present invention are as follows:

[0012] When the patient inhales, the chest cavity of the patient expands, the squeezing airbag contracts, and the high-density gas in the inner cavity of the airbag drives the reset mechanism through the first catheter to push the hydraulic fluid on the right side of its inner cavity to flow to the bottom of the inner cavity of the extraction mechanism, so that the third driving plug pushes the first one-way valve to move upward through the third sliding rod. At this time, the air pressure between the first one-way valve and the second one-way valve in the inner cavity of the pump housing increases, and the high-pressure gas pushes the second one-way valve to close, so that the gas cannot flow to the top of the second one-way valve. The air pressure between the first one-way valve and the second one-way valve pushes the first one-way valve to open. At this time, the gas between the first one-way valve and the second one-way valve flows to the bottom of the first one-way valve and finally flows out of the pump housing through the outlet pipe. When the patient exhales, the first elastic member is reset, and the reset mechanism pushes the high-density gas on its left side to flow back to the inner curved surface of the airbag through the first catheter, so that the airbag recovers and continues to fit closely with the patient's chest cavity. The hydraulic fluid at the bottom of the inner cavity of the extraction mechanism flows back to the inner cavity of the reset mechanism On the right side, at this time, the third driving plug drives the first one-way valve downward through the third sliding rod, the first one-way valve is closed, and the second one-way valve is opened, and the sputum in the patient's trachea flows to between the first one-way valve and the second one-way valve in the inner cavity of the pump casing through the suction pipe and the second one-way valve. At this time, when the patient inhales again, in the same way, the first one-way valve moves upward, the first one-way valve is opened, and the second one-way valve is closed, and the sputum between the first one-way valve and the second one-way valve in the inner cavity of the pump casing flows through the first one-way valve to between the third sliding connection in the inner cavity of the pump casing and the first one-way valve, and finally flows out of the device through the air outlet pipe, thereby stopping the sputum suction for the patient when the patient inhales, and suctioning the patient when the patient exhales, and the operation frequency and intensity are actively and synchronously controlled by the patient himself, overcoming the problem that the existing motor-driven sputum suction device continuously suctions sputum, cannot keep synchronization with the patient's breathing frequency and cannot adjust the sputum suction intensity in time according to the patient's requirements, causing the patient to have difficulty breathing and discomfort.

[0013] 2. When the present invention is used, when the patient inhales, the chest cavity of the patient expands, the airbag is squeezed to contract, and the high-density gas in the airbag cavity flows to the left side of the first driving plug in the inner cavity of the drive shell through the first conduit and pushes the first driving plug to move to the right side. The first driving plug squeezes the first elastic member to contract, and the first driving plug pushes the first sliding plug to move to the right side through the first sliding rod. The first sliding plug pushes the hydraulic fluid on the right side of the first sliding plug in the inner cavity of the drive shell to flow to the extraction mechanism through the first connecting pipe, the coupler and the second conduit in sequence. Conversely, when the patient exhales, the first elastic member is reset, and the first elastic member pushes the first sliding member to move to the extraction mechanism. A driving plug moves to the left, and the first driving plug squeezes the high-density gas on the right side of the first driving plug in the inner cavity of the driving shell, which flows back to the inner curved surface of the airbag through the first conduit, so that the airbag is reset and continues to fit closely with the patient's chest cavity. At the same time, the first driving plug drives the first sliding plug to move to the left through the first sliding rod, and the hydraulic fluid at the bottom of the extraction mechanism flows back to the right side of the first sliding plug in the inner cavity of the driving shell through the second conduit, the connector and the first connecting pipe, thereby achieving complete freedom from dependence on electricity and electronic instruments when the device is used, reducing the production cost of the device while improving the safety performance of the device.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0022] like Figures 1 to 6As shown, an embodiment of the present invention provides a lung clearing and expectoration device for respiratory care, including a curved plate 1, which is made of a lightweight hard material, and the curved plate 1 is made of PVE plastic, thereby reducing the weight of the curved plate 1, reducing the chest pressure of the patient, and improving the comfort of the device when in use. At the same time, it reduces the elastic deformation of the airbag 3 when the patient's chest inhalation compresses the airbag 3 to contract, and increases the compression of the gas in the inner cavity of the airbag 3, thereby improving the working efficiency of the subsequent extraction mechanism 11. A buckle 101 is fixedly installed on the right side of the bottom of the curved plate 1, and a fixing belt 2 is fixedly installed on the left side of the bottom of the curved plate 1. The fixing belt 2 is slidably engaged with the middle part of the buckle 101. The fixing belt 2 is woven from a hard material, and the fixing belt 2 is made of polyester fiber, thereby reducing the elastic deformation of the fixing belt 2, and avoiding that when the chest inhalation compresses the airbag 3 to contract, the airbag 3 drives the fixing belt 2 to lengthen through the curved plate 1, resulting in a reduction in the compression of the airbag 3, causing the subsequent extraction mechanism 11 to work. The working efficiency is reduced, and a plurality of airbags 3 are fixedly installed at equal intervals on the circumference of the inner curved surface of the curved plate 1. The airbags 3 are made of hard rubber, thereby reducing the deformation of the airbag 3 when the patient's chest inhales and compresses the airbag 3 to contract, and improving the working efficiency of the subsequent extraction mechanism 11. The middle part of the airbag 3 is filled with high-density gas, thereby reducing the compression ratio of the gas in the inner cavity of the airbag 3 when the airbag 3 is compressed, and increasing the compression amount of the first elastic member 506 pushed by the first driving plug 505. The rear sides of the plurality of airbags 3 are fixedly sleeved with a first catheter 4, and a reset mechanism 5 is provided at the rear end of the first catheter 4.

A second catheter 10 is fixedly sleeved on the right side of the coupler 7, and an extraction mechanism 11 is provided at the right end of the second catheter 10;

[0023] The extraction mechanism 11 includes a pump housing 1101, the bottom of the pump housing 1101 is fixedly sleeved with the second conduit 10, the bottom of the inner curved surface of the pump housing 1101 is fixedly sleeved with a third sliding joint 1102, the middle of the third sliding joint 1102 is slidably sleeved with a third sliding rod 1103, the bottom end of the third sliding rod 1103 is fixedly installed with a third driving plug 1104, the third driving plug 1104 is slidably sleeved with the inner curved surface of the pump housing 1101, and the contact surface between the third driving plug 1104 and the pump housing 1101 is a smooth surface, thereby improving the contact between the third driving plug 1104 and the pump housing 1101. 1, thereby preventing the hydraulic oil at the bottom of the third driving plug 1104 in the inner cavity of the pump housing 1101 from flowing to the inner cavity of the pump housing 1101, between the third sliding connection 1102 and the third driving plug 1104, causing the subsequent upward movement of the third driving plug 1104 to be blocked, the top of the third sliding rod 1103 is fixedly installed with a first one-way valve 12, the upper part of the inner curved surface of the pump housing 1101 is fixedly installed with a second one-way valve 13, the top of the pump housing 1101 is fixedly installed with an air intake pipe 1105, and the right side of the outer curved surface of the pump housing 1101 is fixedly sleeved with an air outlet pipe 1106.

The right end of the first driving plug 505 is fixedly installed with a first elastic member 506. The right end of the first elastic member 506 is fixedly connected to the first sliding sleeve 502. The first elastic member 506 is made of a hard spring, so as to increase the elastic force of the first elastic member 506 when it is reset, and then the first elastic member 506 pushes the high-density gas on its left side to flow to the inner cavity of the airbag 3 through the first driving plug 505, so that the airbag 3 expands and fits closely with the chest cavity.

[0025] like Figures 1 to 3 As shown, the liquid regulating mechanism 9 includes a liquid pressure shell 901, the front end of which is fixedly sleeved with the second connecting pipe 8, a threaded sleeve 902 is fixedly installed on the rear side of the inner curved surface of the liquid pressure shell 901, and a threaded rod 903 is threadedly connected to the middle part of the threaded sleeve 902. The threaded sleeve 902 is made of self-locking threads, so as to avoid that when the reset mechanism 5 pushes the hydraulic oil to flow to the extraction mechanism 11 and pushes the third driving plug 1104 to move upward, the second driving plug 905 moves backward, causing the third driving plug 1104 to move forward with a reduced amplitude, resulting in reduced working efficiency of the device, a second sliding plug 904 is fixedly installed on the front end of the threaded rod 903, and the second sliding plug 904 is slidably sleeved with the liquid pressure shell 901, and a second driving plug 905 is fixedly installed on the rear end of the threaded rod 903, and the curved surface of the second driving plug 905 is provided with a rough coating, so as to avoid slipping when the second driving plug 905 is manually rotated.

[0026] like Figures 1 to 3 and Figure 5As shown, the first one-way valve 12 includes a first mounting seat 1201, the middle part of the bottom end of the first mounting seat 1201 is fixedly mounted on the top end of the third sliding rod 1103, the first mounting seat 1201 is slidably sleeved with the pump housing 1101, first mounting grooves are symmetrically provided on both sides of the first mounting seat 1201, a first sealing plug 1202 is slidably sleeved on the bottom of the mounting groove, a first connecting block 1203 is fixedly mounted on the middle part of the upper surface of the first sealing plug 1202, a first top block 1204 is fixedly mounted on the upper part of the inner curved surface of the two first connecting blocks 1203, a second elastic member 1205 is fixedly mounted on the bottom end of the first top block 1204, and the bottom end of the second elastic member 1205 is symmetrically sleeved with the top end of the first mounting seat 1201 Fixed connection. When in use, when gas or liquid flows from the top of the first mounting seat 1201 to the bottom of the first mounting seat 1201, the gas or liquid squeezes the first sealing plug 1202 to move downward, and the first sealing plug 1202 compresses the second elastic member 1205 to contract through the first connecting block 1203 and the first top block 1204. At this time, the first sealing plug 1202 is separated from the first mounting groove, allowing the gas or liquid to flow to the bottom of the first mounting seat 1201 through the first mounting groove. When the gas or liquid flows from the bottom of the first mounting seat 1201 to the top of the first mounting seat 1201, the gas or liquid pushes the first sealing plug 1202 upward to fit tightly with the first mounting groove to prevent the gas from flowing upward.

[0027] like Figures 1 to 3 and Figure 6 As shown, the second one-way valve 13 includes a second mounting seat 1301, a second mounting groove is opened in the middle of the second mounting seat 1301, a second sealing plug 1302 is slidably sleeved on the bottom of the second mounting groove, a second connecting block 1303 is fixedly installed in the middle of the upper surface of the second sealing plug 1302, the second connecting block 1303 is slidably sleeved with the second mounting seat 1301, and a gap is left between the curved surface of the second connecting block 1303 and the inner curved surface of the second mounting seat 1301, so that the gas and liquid flowing downward from the top of the second mounting seat 1301 can directly contact the upper surface of the second sealing plug 1302 through the gap between the second connecting block 1303 and the second mounting seat 1301, pushing the second sealing plug 1302 to move downward, a second top block 1304 is fixedly installed on the top of the second connecting block 1303, a third elastic member 1305 is fixedly installed on the bottom end of the second top block 1304, and the bottom end of the third elastic member 1305 is fixedly connected to the upper surface of the second mounting seat 1301.

[0028] Working principle:

[0029] When the present invention is used, the curved plate 1 is first placed in the middle of the patient's chest, and the airbag 3 is in contact with the patient's chest. Then, the fixing belt 2 is passed around the patient's back, and the fixing belt 2 is fixedly connected to the middle of the buckle 101. Then, the second driving plug 905 is rotated forward, and the second driving plug 905 drives the threaded rod 903 to rotate, and the threaded rod 903 moves forward. The threaded rod 903 drives the second sliding plug 904 to move forward, and the second sliding plug 904 squeezes the hydraulic fluid in the front side of the second driving plug 905 in the inner cavity of the pressure liquid shell 901 to flow to the coupler 7 through the second connecting pipe 8, and finally flows to the right side of the first sliding plug 504 in the inner cavity of the driving shell 501 through the first connecting pipe 6, and flows to the bottom end of the third driving plug 1104 in the inner cavity of the pump shell 1101 through the second conduit 10, and then the suction pipe 1105 is inserted into the patient's trachea;

[0030] At this time, when the patient inhales, the patient's chest cavity expands, squeezing the airbag 3 to contract, and the high-density gas in the inner cavity of the airbag 3 flows to the left side of the first driving plug 505 in the inner cavity of the driving shell 501 through the first conduit 4. At this time, the high-density gas pushes the first driving plug 505 to move to the right, and the first driving plug 505 squeezes the first elastic member 506 to contract. The first driving plug 505 pushes the first sliding plug 504 to move to the right through the first sliding rod 503, and the first sliding plug 504 pushes the hydraulic fluid on the right side of the first sliding plug 504 in the inner cavity of the driving shell 501 to flow to the bottom end of the third driving plug 1104 in the inner cavity of the pump shell 1101 through the first connecting pipe 6, the coupler 7 and the second conduit 10 in turn. At this time, the hydraulic fluid pushes the third driving plug 1104 to move upward, and the third driving plug 1104 pushes the first one-way valve 12 to move upward through the third sliding rod 1103. The air pressure between the first one-way valve 12 and the second one-way valve 13 in the cavity increases. At this time, the third elastic member 1305 drives the second sealing plug 1302 to fit tightly upward with the first mounting groove through the second top block 1304 and the second connecting block 1303, so that the second one-way valve 13 is closed, and the gas cannot flow to the top of the second one-way valve 13. The high-pressure air pressure between the first one-way valve 12 and the second one-way valve 13 pushes the first sealing plug 1202 to move downward through the upper part of the second mounting groove. The first sealing plug 1202 drives the first top block 1204 to move downward through the first connecting block 1203, and the first top block 1204 squeezes the second elastic member 1205 downward to contract. At this time, the first one-way valve 12 is opened, and the gas between the first one-way valve 12 and the second one-way valve 13 flows to the bottom of the first one-way valve 12, and finally flows out of the pump housing 1101 through the air outlet pipe 1106;

[0031] When the patient exhales, the first elastic member 506 is reset, and the first elastic member 506 pushes the first driving plug 505 to move to the left. The first driving plug 505 squeezes the high-density gas on the right side of the first driving plug 505 in the inner cavity of the driving shell 501, and flows back to the inner cavity of the airbag 3 through the first conduit 4, so that the airbag 3 is reset and continues to fit closely with the patient's chest cavity. At the same time, the first driving plug 505 drives the first sliding plug 504 to move to the left through the first sliding rod 503, and the hydraulic fluid at the bottom of the third driving plug 1104 in the inner cavity of the pump shell 1101 flows back to the right side of the first sliding plug 504 in the inner cavity of the driving shell 501 through the second conduit 10, the connector 7 and the first connecting pipe 6. At this time, the third driving plug 1104 moves downward, and the third driving plug 1104 drives the first one-way valve 12 to move downward through the third sliding rod 1103. The first one-way valve 12 is closed, and the second one-way valve 13 is opened. The sputum in the patient's trachea is sucked out. The trachea 1105 and the second one-way valve 13 flow to the inner cavity of the pump housing 1101, between the first one-way valve 12 and the second one-way valve 13. At this time, when the patient inhales again, similarly, the first one-way valve 12 moves upward, the first one-way valve 12 opens, and the second one-way valve 13 closes. The sputum between the first one-way valve 12 and the second one-way valve 13 in the inner cavity of the pump housing 1101 flows through the first one-way valve 12 to the inner cavity of the pump housing 1101, between the third sliding joint 1102 and the first one-way valve 12, and finally flows out of the device through the air outlet pipe 1106, thereby stopping the sputum suction of the patient when the patient inhales, and suctioning the patient when the patient exhales, and the operation frequency and intensity are actively and synchronously controlled by the patient himself, thereby overcoming the problem that the existing motor-driven sputum suction device continuously suctions sputum, cannot keep synchronization with the patient's breathing frequency and cannot adjust the sputum suction intensity in time according to the patient's requirements, causing the patient to have difficulty breathing and discomfort.
