Description

Technical Field

[0001] The invention relates to the technical field of sputum suction nursing devices, in particular to a sputum suction device used for pediatric nursing. Background Art

[0002] Suction pumps are mainly divided into two categories: electric multifunctional negative pressure suction pumps and simple manual suction pumps. When in use, the operating end needs to be connected to a suction tube or a sponge suction tube to work properly. Generally, it is recommended to use an electric suction pump because it is equipped with a power switch and a manual control button. It uses the negative pressure principle to achieve an efficient and safe suction process and oral care, and its operation is simple and easy to understand. The suction tube of the suction pump is inserted into the respiratory tract and uses negative pressure to suck out respiratory secretions. This type of equipment is widely used in daily suction treatment of the wounded and sick, post-tracheotomy care, and other scenarios. It is not only suitable for military field medical environments, but also very suitable for emergency treatment of excessive respiratory secretions or vomiting in hospitals and even home environments; The current suction devices are relatively simple in function, especially when the suction tube is inserted into the respiratory tract, which may cause varying degrees of irritation to the throat and tracheal mucosa. For children, this discomfort is particularly obvious, causing them to be irritable and uncooperative, thus affecting the efficiency of suction. In addition, when there is dry and highly viscous sputum in the throat of a child patient, this type of sputum tends to adhere to the throat wall and is not easy to fall off. Existing sputum suction equipment has certain limitations when dealing with this type of sputum. It is usually necessary to dilute the sputum first through expectorants and local atomization treatment, so that the sputum can be cleared more effectively. However, the expectorant drugs inhaled by atomization cannot directly reach the location of the sputum, and will be partially absorbed by the respiratory tract, resulting in unsatisfactory treatment effects. In addition, young children have a low degree of cooperation during the treatment process, and the complex treatment process may increase their discomfort, leading to restlessness during the suction process, further reducing the suction effect; In actual operation, the operator mainly relies on the sound changes when the stethoscope is running and the difference in resistance to judge whether the sputum is successfully sucked out. However, this method cannot accurately evaluate the specific effect of each suction. Considering safety factors, it is recommended that the single suction time should not exceed 15 seconds, and the entire continuous suction process should not exceed 3 minutes to avoid causing hypoxia and other problems. Therefore, how to efficiently locate and remove sputum in a limited time, at the same time, a technical means that can provide real-time feedback on the suction effect is also needed, so that medical staff can adjust the operation strategy in time to improve the efficiency and safety of suction.

The micro camera generates data according to the image of the throat in real time, and then the controller transmits the data to the control panel for display, so that medical staff can observe the insertion of the suction hose in time. When the suction hose contacts the throat mucosa, the suction hose can be rotated to adjust the position to minimize the contact time of the suction hose on the throat mucosa and reduce the discomfort of the child patient's throat, thereby solving the problem that when the suction tube is inserted into the respiratory tract, it may cause different degrees of stimulation to the throat and tracheal mucosa, which will cause the child patient to be irritable and poorly cooperative, thereby affecting the suction efficiency.

When the sputum is dry, it is only necessary to inject warm sputum diluting liquid into the inner cavity of the liquid storage shell. When the temperature is appropriate, the controller controls the electric control valve to open to allow the liquid medicine to flow. At the same time, the controller controls the flow of the liquid medicine through the electronic flow valve. The liquid medicine flows to the medical capillary plate through the connecting tube. When the liquid medicine in the inner cavity of the medical capillary plate flows out, it will directly act on the sputum. At the same time, the medical staff observes the dilution degree of the sputum in real time through the micro camera, so as to efficiently suck out the sputum, thereby solving the problem that the sputum in the throat is relatively dry and has high viscosity, which is more likely to adhere to the throat wall and is not easy to fall off, further reducing the sputum suction effect.

[0018] The present invention can realize timely cleaning of the sputum suction device used for pediatric care by arranging a cleaning component in the sputum suction device. When the magnetic fixing block fixes the liquid storage bottle on the inner wall of the magnetic base, it is only necessary to pull the flexible metal conduit to drive the high-pressure nozzle to move to one side of the liquid storage bottle, so that the control panel controls the liquid pump to operate, and then the high-pressure nozzle sprays the liquid, which will cause the liquid to flush the bottle body, making it convenient to clean the liquid storage bottle in time. At the same time, the flushed waste liquid flows to the connecting groove through the guide shell, and then the waste liquid flows into the inner cavity of the waste liquid shell for collection. The ultraviolet disinfection lamp will disinfect the sputum suction hose, and the constant temperature plate will heat the sputum suction hose at a constant temperature, so that the sputum suction device has better practicality.

A disinfection lamp 507 is provided, a constant temperature plate 508 is provided directly below the suction hose 506 and on the inner wall of the storage shell 501, a flexible partition 509 is provided on the inner wall of the suction hose 506, and the flexible partition 509 divides the inner cavity of the suction hose 506 into a suction cavity 510 and a closed cavity 511, a connector 512 is installed at one end of the suction hose 506, a liquid storage shell 513 is installed on the outer wall of the connector 512, a connecting conduit 514 is installed on the outer wall of the liquid storage shell 513, and a controller 514 is embedded and installed on one side of the connector 512 and on the outer wall of the suction hose 506 5. A wireless antenna 516 is embedded in the outer wall of the controller 515. A connecting tube 517 is installed on the outer wall of the controller 515. One end of the connecting tube 517 is connected to the connecting catheter 514. The other end of the connecting tube 517 passes through the suction hose 506 and extends to the inner cavity of the suction hose 506. The connecting tube 517 is located in the inner cavity of the closed cavity 511. The other end of the suction hose 506 is connected to the flexible shell 519 through the threaded tube 518. A medical capillary plate 520 is embedded in the outer wall of the flexible shell 519. The medical capillary plate 520 is in a ring structure. The medical capillary plate 520 is in a ring structure. The inner wall of the medical capillary plate 520 is connected to a connecting tube 517, an electronic flow valve 521, an electric control valve 522 and a temperature sensor 523 are sequentially arranged on one side of the medical capillary plate 520 and on the outer wall of the connecting tube 517, a connecting hole 524 is arranged on one side of the medical capillary plate 520 and on the outer wall of the flexible shell 519, the connecting holes 524 are arranged in multiple groups and form a ring array structure, positive electrode contacts 525 and negative electrode contacts 526 are respectively arranged on the opposite inner walls of the connecting holes 524, and a micro camera 527 is embedded and installed on one side of the connecting hole 524 and on the top outer wall of the flexible shell 519; Based on the above structural features and the connection relationship, the micro camera 527 has a ring-shaped lighting structure. When the micro camera 527 is in use, the lighting of the micro camera 527 can better observe the affected area. At the same time, because the ultraviolet disinfection lamps 507 are arranged in an array from left to right just above the suction hose 506 and on the inner wall of the cover plate 502, and the constant temperature plate 508 is arranged just below the suction hose 506 and on the inner wall of the storage shell 501, when not in use, the ultraviolet disinfection lamps 5 07 will disinfect the suction hose 506, and the constant temperature plate 508 will heat the suction hose 506 at a constant temperature. Under the action of the wireless antenna 516 embedded in the outer wall of the controller 515, the controller 515 and the control panel 6 are connected through the wire for electrical signal transmission. At the same time, the controller 515 and the control panel 6 can also be connected through the wireless antenna 516 for wireless transmission. The medical capillary plate 520 is a polymer porous structure, so that the liquid medicine can be saturated through the capillary porous structure to dilute the sputum, which is more practical. Among them, the connection method between the suction hose 506 and the threaded tube 518 is threaded connection, the connection method between the suction hose 506 and the flexible shell 519 is threaded connection, and the control panel 6 is connected to the negative pressure suction pump 2, the liquid pump 407, the controller 515, the electronic flow valve 521, the electric control valve 522, the temperature sensor 523 and the micro camera 527 through wires and the connection method is electrical connection, so that the device is powered on, and then the control panel 6 controls the negative pressure suction pump 2, the liquid pump 407, the controller 515, the electronic flow valve 521, the electric control valve 522, the temperature sensor 523 and the micro camera 527 to power on and operate.

[0025] When the sputum suction device for pediatric care of the present invention is in operation, the handle 504 is pulled to cause the handle 504 to drive the cover plate 502 to move upward, thereby opening the cover plate 502, and then the sputum suction hose 506 is taken out, and one end of the sputum suction hose 506 is inserted into the port of the liquid inlet pipe 94 through the connecting piece 512 for fixing. When the device is assembled, only the other end of the sputum suction hose 506 needs to be inserted into the patient's throat. When the sputum suction hose 506 is inserted, its micro camera 527 generates data in real time according to the image of the throat, and then the micro camera 527 transmits the data to the patient through the wire. Controller 515, then controller 515 transmits data to control panel 6 for display, so that medical staff can timely observe the insertion status of suction hose 506. When suction hose 506 contacts throat mucosa, suction hose 506 can be rotated to adjust the position, so as to minimize the contact time of suction hose 506 on throat mucosa and reduce the discomfort of throat of child patients, thereby solving the problem that when suction tube is inserted into respiratory tract, it may cause different degrees of stimulation to throat and tracheal mucosa, which may cause irritability and poor cooperation of child patients, thus affecting suction efficiency. The micro camera 527 is used to observe the throat in real time, so that the sputum suction hose 506 can directly reach the position of the sputum. At the same time, when the sputum suction tube assembly 5 contacts the sputum, the sputum will first contact the flexible shell 519. When the sputum flows to the connecting hole 524, when the sputum completely fills the inner wall of the connecting hole 524, the sputum will contact the positive electrode contact 525 and the negative electrode contact 526 at the same time, thereby forming a path between the positive electrode contact 525 and the negative electrode contact 526. At this time, the electrical signal sent by the controller 515 can be transmitted between the positive electrode contact 525 and the negative electrode contact 526. On the contrary, when there is no sputum on the inner wall of the connecting hole 524, the positive electrode contact 525 and the negative electrode contact 526 are disconnected, which will prevent the electrical signal of the controller 515 from being transmitted between the positive electrode contact 525 and the negative electrode contact 526. By providing a plurality of groups of connecting holes 524 in a circular array on the outer wall of the flexible shell 519, it is possible to infer whether the electric signal emitted by the controller 515 can be conducted through the positive electrode contact piece 525 and the negative electrode contact piece 526, and whether the sputum suction tube assembly 5 is in contact with the sputum. Meanwhile, the connecting holes 524 with sputum can conduct signals, while the connecting holes 524 without sputum cannot conduct signals. The controller 515 only needs to judge the on-off status of the plurality of groups of positive electrode contact pieces 525 and negative electrode contact pieces 526 to infer the approximate contact area between the sputum suction tube assembly 5 and the sputum. Then, the controller 515 generates an electric signal which is conducted to the control panel 6 through the wire. To turn on the sputum suction switch of the control panel 6, the control panel 6 will control the negative pressure suction pump 2 to operate. When the negative pressure suction pump 2 is in operation, the negative pressure suction pump 2 will suck out the gas in the inner cavity of the liquid storage bottle 9 through the filter 3, thereby creating a negative pressure environment in the inner cavity of the liquid storage bottle 9. Subsequently, the gas in the inner cavity of the sputum suction hose 506 is also sucked out to generate negative pressure, which will cause the sputum suction tube assembly 5 at the end of the sputum suction hose 506 to suck out the sputum. At the same time, when the sputum in the inner cavity of the connecting hole 524 of the outer wall of the flexible shell 519 is sucked away, the positive electrode connector 525 and the negative electrode connector 526 at the connecting hole 524 will also be disconnected, thereby timely judging the sputum suction effect. The micro camera 527 is used to observe the throat in real time, so that the sputum suction hose 506 can directly reach the position of the sputum. At the same time, the connecting hole 524 with sputum can transmit signals, and the connecting hole 524 without sputum cannot transmit signals. The controller 515 only needs to judge the on-off status of multiple groups of positive electrode contacts 525 and negative electrode contacts 526 to infer that the sputum suction tube assembly 5 is in contact with the sputum. When the sputum at the connecting hole 524 of the flexible shell 519 is sucked away, the positive electrode contact 525 and the negative electrode contact 526 at the connecting hole 524 will also be disconnected, and then the sputum suction effect can be timely judged, thereby solving the problem of how to efficiently locate and remove sputum within a limited time. At the same time, a method that can provide real-time feedback on the sputum suction effect is also needed; By using the image transmitted by the micro camera 527, the medical staff can determine whether the sputum in the patient's throat is dry. When the sputum is dry, it is only necessary to inject warm sputum-diluting liquid into the inner cavity of the liquid storage shell 513, so that the liquid in the inner cavity of the liquid storage shell 513 flows into the inner cavity of the connecting tube 517 through the connecting conduit 514 in turn. At the same time, when the temperature sensor 523 generates an electrical signal in real time according to the temperature of the liquid, the electrical signal generated by the temperature sensor 523 is transmitted to the controller 515 through the wire. When the set value is reached, the controller 515 controls the electric control valve 522 to open, so that the liquid medicine flows to one side of the connecting tube 517. At the same time, the controller 515 controls the electric control valve 522 to open, so that the liquid medicine flows to one side of the connecting tube 517. 21 controls the flow of the liquid medicine, which then flows through the connecting tube 517 to the medical capillary plate 520. When the suction tube assembly 5 is in contact with the sputum, the medical capillary plate 520 is also located on one side of the sputum. When the liquid medicine in the inner cavity of the medical capillary plate 520 flows out, it will directly act on the sputum. Compared with the inhaled atomized liquid medicine, it has a better dilution and lubrication effect on dry sputum, and also prevents the liquid medicine from irritating the mucous membrane of the throat. At the same time, the medical staff observes the dilution degree of the sputum in real time through the micro camera 527, so as to efficiently suck out the sputum, thereby solving the problem that the sputum in the throat is relatively dry and has high viscosity, which is more likely to adhere to the throat wall and is not easy to fall off, further reducing the suction effect.
