Description

Technical Field

[0001] This invention relates to the field of pharyngeal surgical ventilation technology, and more specifically to a multi-channel oropharyngeal ventilation device for anesthesiology. Background Technology

[0002] Anesthesia in the anesthesiology department can eliminate patients' mental tension before surgery, and at the same time, it can have sedative, analgesic, and muscle relaxant effects during the operation, thereby meeting the requirements of the operation and ensuring the patient's life safety during the operation. During anesthesia, the anesthesiology department usually uses a pharyngeal ventilation device to intubate the oropharynx. The ventilation device establishes a breathing channel in the oropharynx, which helps the patient exhale and inhale, and avoids the inability to breathe smoothly due to anesthesia or shock. In summary, the inventors have found that existing ventilation devices have the following main defects: because current ventilation devices usually use multiple channels to simultaneously intubate the oropharynx, they can deal with excessive saliva and phlegm in the oropharynx while establishing a breathing channel; Therefore, the temperature of a multi-channel ventilation device depends on the indoor temperature of the operating room. When the ventilation device is inserted into the patient's oropharyngeal area, the oropharynx is easily affected by the cold factor and will contract slightly. This will increase the ease of insertion of the ventilation device, but at the same time, it will not be able to balance the temperature of the cold air. When the patient inhales the cold air, he will feel uncomfortable inside his body, which will reduce the effectiveness of the ventilation device. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a multi-channel oropharyngeal ventilation device for anesthesiology, the structure of which includes: a wear body, a positioning block, a connecting group, a ventilation tube, a suction tube, and a suction tube. The upper center of the wear body overlaps with the positioning block. The connecting group is embedded in the central area of ​​the positioning block. The ventilation tube passes through the bottom center of the wear body and the positioning block and is connected to the central part of the connecting group. The suction tube and the suction tube pass through the left and right areas of the wear body and the positioning block in a left-right direction and are connected to the connecting group of the left and right areas.

[0004] As a further improvement of the present invention, the wearable body comprises a medical plastic block, a carrier layer, a battery block, a charging port, a control terminal, a power-conducting block, a fixing groove, and a thermostatic tube. The upper end of the medical plastic block is integrated with the carrier layer. The battery block is embedded in the inner left side of the surface layer of the carrier layer. The charging port is integrated with the top of the battery block. The control terminal is located on the right side of the carrier layer and is electrically connected to the battery block. The power-conducting block is installed at the center of the edge of the control terminal. The fixing groove extends from the center of the top of the medical plastic block. The thermostatic tube is positioned at the lower end of the fixed groove and is electrically connected to the control terminal via an energizing block. The thermostatic tubes overlap with the ventilation tube, suction tube, and suction tube, respectively. The medical plastic block is fitted with a medical rubber plate at the point of contact with the patient. The carrier layer is flattened. The charging hole on the battery block has an insulating wall at its edge. The control terminal has three sets of control components arranged on the left, center, and right. The energizing block is a solid square. The fixed groove is a rectangular recess with three through holes. There are a total of three thermostatic tubes.

[0005] As a further improvement of the present invention, the upper end of the constant temperature pipe is provided with a conductive block, a heating body, a diffuser block, a vertical sleeve, and a through hole. The conductive block is fixed to both sides of the upper end of the heating body. The lower edge of the heating body is connected to the diffuser block. The vertical sleeve is embedded in the top center of the heating body. The through hole passes through the central area of ​​the vertical sleeve and the heating body. The heating body is parallel to and attached to the lower part of the fixing groove. The conductive block is electrically connected to the control end. The diffuser block is embedded in the inner edge of the vent pipe. The conductive block is a small cylindrical shape. Four metal diffuser blocks are installed on the lower edge of the heating body. The diameter of the vertical sleeve is larger than the diameter of the conductive block and is located in the center of the heating body.

[0006] As a further improvement of the present invention, a temperature conducting rod, a connecting ring, a protrusion, and an anti-deviation block are newly provided at the lower center of the diffuser block. The upper end of the temperature conducting rod is fixedly connected to the connecting ring and is located at the same center point. The protrusion is vertically welded to the top area of ​​the connecting ring. The anti-deviation block is welded to the lower edge of the temperature conducting rod. The temperature conducting rod is fixed to the lower center of the diffuser block through the connecting ring and the protrusion. The anti-deviation block is fixedly connected to the lower inner edge of the vent pipe through the temperature conducting rod. The temperature conducting rod is made of graphene material. The diameter of the connecting ring is larger than the top diameter of the temperature conducting rod. The protrusion is a magnetic metal product. The anti-deviation block is cylindrical and fixed to the lower edge of the temperature conducting rod in a horizontal straight line.

[0007] As a further improvement of the present invention, the connecting ring is provided with a ring body, a parallel layer, and a limiting slot. The ring body and the parallel layer are an integrated structure. The limiting slot passes through the central area of ​​the ring body through the parallel layer. The upper part of the ring body is welded to the protrusion through the limiting slot of the parallel layer. The lower part of the ring body is fixedly connected to the top of the temperature conduction rod through the limiting slot. The ring body is solid and the inner wall of the limiting slot is finely polished.

[0008] As a further improvement of the present invention, a positioning body, an overlapping rail, a bearing ring, a telescopic shaft, and a push block are newly provided in the outer periphery of the middle section of the constant temperature pipe fitting. The center of the positioning body is penetrated by the overlapping rail, and the edge of the overlapping rail is penetrated by the bearing ring. The telescopic shaft is positioned in the edge area of ​​the bearing ring, and the push block is fixed to the top of the telescopic shaft. The push block is set below the fixing groove through the telescopic shaft and the positioning body. The telescopic shaft is electrically connected to the control terminal through a power block. The positioning body is set in the middle section of the outer layer of the vent pipe through the overlapping rail. The positioning body is circular in shape, and the diameter of the bearing ring is larger than the diameter of the overlapping rail. There are four sets of telescopic shafts and push blocks arranged in four directions.

[0009] As a further improvement of the present invention, the push block is provided with a connecting end, a solid block, an overlapping layer, and a medical rubber block. The connecting end and the solid block are an integrated structure. The top of the solid block is fixedly connected to the medical rubber block through the overlapping layer. The solid block is connected to the top of the telescopic shaft through the connecting end. The solid block is arc-shaped. The surface of the overlapping layer is finely polished. The shape of the medical rubber block is consistent with the shape of the solid block.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention further improves the wearable body by using a rechargeable battery block installed in a medical plastic block to provide electrical energy to the control end. Then, the control end controls the thermostatic tube, which uses a heating element and a diffuser to balance the temperature of the ventilation tube, suction tube, and suction tube. This raises the temperature of the inhaled oxygen, preventing excessive coldness that could irritate the oropharyngeal area, and thus ensuring the stability of the ventilation device in assisting the patient with oxygen inhalation.

[0011] 2. The present invention features a temperature conduction rod added to the lower end of the diffuser block, which can be made of graphene material. Utilizing the bendability and thermal conductivity of graphene, the rod is stably fixed to the inner layer of the thermostatic tubing via protrusions and anti-deviation blocks, preventing positional shifts that occur when the ventilation tube, suction tube, or suction tube is bent. Then, by covering and fixing the rod at the origin point, the temperature of the heating element is conducted downwards, improving the speed and uniformity of temperature control for the ventilation tube, suction tube, or suction tube by the thermostatic tubing. This replaces the slow and uneven temperature expansion caused by using the diffuser block alone.

[0012] 3. The present invention features a new positioning body added to the middle section of the outer layer of the constant temperature tube. This positioning body uses a bearing ring to determine the positions of four sets of telescopic shafts and push blocks. Thus, the telescopic shafts and push blocks can enter the patient's oropharynx according to the airway. When the patient's oropharynx is stimulated and contracts, the telescopic shafts can drive the push blocks to slowly push outward. This allows the medical rubber block of the push block to contact the oropharyngeal area, thereby forcibly opening the oropharynx and improving the convenience of treatment. At the same time, the use of medical rubber can avoid scratching and injury to the oropharynx during the pushing process, ensuring the integrity of the patient's oropharynx.

Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings: Example

[0022] Figures 1 to 5 As shown: This invention provides a multi-channel oropharyngeal ventilation device for anesthesiology. Its structure includes a wearable body 1, a positioning block 2, a connecting group 3, a ventilation tube 4, a suction tube 5, and a suction tube 6. The upper center of the wearable body 1 overlaps with the positioning block 2. The connecting group 3 is embedded in the central area of ​​the positioning block 2. The ventilation tube 4 passes through the bottom center of the wearable body 1 and the positioning block 2 and is connected to the central part of the connecting group 3. The suction tube 5 and the suction tube 6 pass through the left and right areas of the wearable body 1 and the positioning block 2 in a left-right direction and are connected to the connecting group 3 in the left and right areas.

[0023] The wearable device 1 includes a medical plastic block 11, a carrier layer 12, a battery block 13, a charging port 14, a control terminal 15, a power-conducting block 16, a fixing groove 17, and a thermostatic tube 18. The upper end of the medical plastic block 11 is integrated with the carrier layer 12. The battery block 13 is embedded in the left side of the surface of the carrier layer 12. The charging port 14 is integrated with the top of the battery block 13. The control terminal 15 is located on the right side of the carrier layer 12 and is electrically connected to the battery block 13. The power-conducting block 16 is installed at the center of the edge of the control terminal 15. The fixing groove 17 is located at the center of the top of the medical plastic block 11. The thermostatic tube 18 is positioned at the lower end of the fixing groove 17 and is electrically connected to the control terminal 15 through the energizing block 16. The thermostatic tube 18 overlaps with the ventilation tube 4, the suction tube 5, and the suction tube 6, respectively. The medical plastic block 11 is equipped with a medical rubber plate at the part that contacts the patient. The carrier layer 12 is flattened. The charging hole 14 on the battery block 13 has an insulating wall at its edge. The control terminal 15 is provided with three sets of control components arranged on the left, center, and right. The energizing block 16 is a solid square. The fixing groove 17 is a rectangular recessed shape and has three through holes. There are a total of three thermostatic tubes 18. The medical plastic block 11, with its underlying medical rubber plate, prevents scratching of the patient. The carrier layer 12, with its flattened shape, prevents tilting after the component is installed. The insulating wall around the charging port on the battery block 13 prevents leakage during charging. The three sets of control components on the control terminal 15 can electrically control the thermostatic tube 18 in the same position. The energizing block 16, with its solid square shape, improves the stability of power transmission. The fixing groove 17, with its rectangular recessed shape, can be adapted to the shape of the component, and its three through holes allow the thermostatic tube 18 to be inserted and fixed, achieving vertical alignment with the component.

[0024] The thermostatic fitting 18 is provided with a conductive block 181, a heating body 182, a diffuser block 183, a vertical sleeve 184, and a through hole 185 at its upper end. The conductive block 181 is fixed to both sides of the upper end of the heating body 182. The lower edge of the heating body 182 is connected to the diffuser block 183. The vertical sleeve 184 is embedded in the top center of the heating body 182. The through hole 185 passes through the central area of ​​the vertical sleeve 184 and the heating body 182. The heating body 182 is parallel to and attached to the lower part of the fixing groove 17. The conductive block 181 is electrically connected to the control terminal 15. The diffuser block 183 is embedded in the inner edge of the vent pipe 4. The conductive block 181 is a small cylindrical shape. Four metal diffuser blocks 183 are installed on the lower edge of the heating body 182. The diameter of the vertical sleeve 184 is larger than the diameter of the conductive block 181 and is located in the center of the heating body 182. The conductive block 181, with its small cylindrical shape, can be inserted vertically into the inner layer of the component to achieve stable electrical conductivity. The four metal diffusion blocks 183 on the lower edge of the heating body 182 can guide the temperature of the heating body 182 and then diffuse the heat energy according to its own shape. The vertical sleeve 184, through its own diameter and position, can ensure the vertical fixation of the origin of the heating body 182.

[0025] The diffuser block 184 is further equipped with a temperature conduction rod a1, a connecting ring a2, a protrusion a3, and an anti-deviation block a4 at its lower center. The upper end of the temperature conduction rod a1 is fixedly connected to the connecting ring a2 and is located at the same center point. The protrusion a3 is vertically welded to the top area of ​​the connecting ring a2. The anti-deviation block a4 is welded to the lower edge of the temperature conduction rod a1. The temperature conduction rod a1 is fixed to the lower center of the diffuser block 184 through the connecting ring a2 and the protrusion a3. The anti-deviation block a4 is fixedly connected to the lower inner edge of the vent pipe 4 through the temperature conduction rod a1. The temperature conduction rod a1 is made of graphene material. The diameter of the connecting ring a2 is larger than the top diameter of the temperature conduction rod a1. The protrusion a3 is a magnetic metal product. The anti-deviation block a4 is cylindrical and is fixed to the lower edge of the temperature conduction rod a1 in a horizontal straight line. The temperature conduction rod a1, enhanced by graphene material, achieves flexibility and easy thermal conductivity. Furthermore, fixing the temperature conduction rod a1 to the inner layer of the component improves the uniformity of temperature conduction and avoids the inability to bend after installation. The connecting ring a2, with its large diameter, can fix the top of the temperature conduction rod a1. Then, the magnetic attraction of the protrusion a3 limits the position of the top of the temperature conduction rod a1. The anti-deviation block a1, with its cylindrical shape and lateral fixation, can lock with the lower inner edge of the component, preventing damage to the bottom overlap during insertion and bending processes, thus ensuring the fixed position of the temperature conduction rod a1.

[0026] The connecting ring a2 comprises a ring body a21, a parallel layer a22, and a limiting slot a23. The ring body a21 and the parallel layer a22 are an integral structure. The limiting slot a23 passes through the parallel layer a22 and extends into the central area of ​​the ring body a21. The upper part of the ring body a21 is welded to the protrusion a3 through the limiting slot a23 of the parallel layer a22. The lower part of the ring body a21 is fixedly connected to the top of the temperature conduction rod a1 through the limiting slot a23. The ring body a21 is solid, and the inner wall of the limiting slot a23 is finely polished. The solid shape of the ring a21 can improve the load-bearing strength of the component through the limiting slot a23. The inner wall of the limiting slot a23 is finely polished to prevent tilting after the component is installed or edge jamming caused by the assembly process.

[0027] The specific functions and operation procedures of this embodiment are as follows: In this invention, First: The multi-channel oropharyngeal ventilation device for anesthesiology can determine the position of the positioning block 2 by using the center of the top of the wearer 1. The connecting group 3 on the positioning block 2 will then connect to external medical equipment using the threaded characteristics. The left, middle and right areas of the lower end of the connecting group 3 can be connected to the suction tube 5, the ventilation tube 4 and the suction tube 6, respectively. This allows the ventilation tube 4 to establish an assisted breathing channel after entering the patient's oropharyngeal area. Furthermore, the connecting group 3 in the center area of ​​the positioning block 2 can be connected to external oxygen cylinders and other components. At the same time, the suction tube 5 and the suction tube 6 located on the left and right sides of the ventilation tube 4 can be connected to the special suction components. When there is saliva or sputum at the edge of the oropharynx, excess saliva and sputum can be suctioned out through the corresponding tubes and suction components to avoid excessive accumulation and affect normal treatment. Second: The wearable device 1 can make contact with the patient's external environment through the medical plastic block 11. Then, the battery block 13 installed in the flattened carrier layer 12 of the medical plastic block 11 can be charged through the charging port 14. Thus, the control terminal 15, with the power of the battery block 13, can electrically control the thermostatic tube 18 at the lower end of the fixing groove 17 through the energizing block 16. As a result, the positioning block 2 and the connecting group 3 on the fixing groove 17 will overlap with the three thermostatic tubes 18 in the left, center, and right directions, forcing the thermostatic tubes 18 to connect with the ventilation tube 4, suction tube 5, and suction tube 6. Then, the control terminal 1... After the thermostatic fittings 18 are activated, they will be heated, which will raise the temperature of the ventilation tube 4. This will prevent the ventilation tube 4 from causing a low-temperature irritation reaction when it enters the patient's oropharynx at a warm temperature, thus improving the connection between the ventilation tube 4 and the oropharynx and enhancing the stability of establishing an assisted breathing channel. At the same time, it can raise the temperature of the inhaled oxygen, improving the reliability of oxygen intake to the patient's internal organs. Meanwhile, the suction tube 5 and the suction tube 6 can make direct contact with the patient's oropharynx during use because their temperatures are the same as those of the ventilation tube 4, preventing irritation to the edges of the oropharynx caused by temperature inconsistencies with the ventilation tube 4. Third: The heating element 182 of the constant temperature tube 18 can be embedded into the lower end area of ​​the fixing groove 17 through the conductive blocks 181 on both sides of the surface. Then, it is electrically connected to the power block 16 through the conductive blocks 181. Subsequently, the control end 15 can control the heating element 182 through the conductive blocks 181. After the temperature of the heating element 182 rises, it will use four sets of diffusion blocks 183 on the lower edge to diffuse the temperature. With the support of the diffusion blocks 183, the verticality of the connection to the ventilation tube 4, suction tube 5 or suction tube 6 can be improved, and the heat energy of the heating element 182 can be diffused into the tube body to achieve the effect of temperature balance. The vertical sleeve 184 in the center of the surface of the heating element 182 can be directly inserted into the lower end of the fixing groove 17. Then, the through hole 185 it carries coincides with the center of the tube body, so that the gas can flow through the through hole 185 area, improving the ventilation effect of the patient's oropharynx. Fourth: The newly added temperature conduction rod a1 at the lower center of the diffuser block 183 will be fixed to the lower center of the diffuser block 183 through the connecting ring a2 and the protrusion a3. Then, the anti-deviation block a4 at the lower edge of the temperature conduction rod a1 can be fixed to the lower edge of the ventilation tube 4, the suction tube 5 or the suction tube 6 by its own lateral direction, so as to improve the connection balance between the constant temperature tube 18 and the ventilation tube 4. Furthermore, the temperature conduction rod a1, with the flexibility and thermal conductivity of graphene material, can prevent the inability to bend caused by the connection between components, ensuring the normal establishment of the breathing channel of the components. At the same time, the thermal conductivity can conduct heat energy in a vertical direction, replacing the original diffusion process of the diffuser block 183. With the cooperation of the vertical temperature conduction rod a1, the temperature balance uniformity of the constant temperature tube 18 can be improved, ensuring that all corner areas can get a temperature rise, indirectly improving the speed of temperature balance. Fifth: The ring body a21 of the connecting ring a2 will be solid to improve the stability of the cross assembly with the temperature conduction rod a1. Then, the finely polished parallel layer a22 can fit with the lower center of the diffuser block 183 to prevent tilting. Finally, the upper and lower middle areas of the limiting slot a23 of the ring body a21 can restrain the center point of the protrusion a3 and the temperature conduction rod a1 respectively, ensuring that the protrusion a3 and the temperature conduction rod a1 can be kept on the same vertical line, improving the vertical fixation of the temperature conduction rod a1 and ensuring accurate temperature transmission. Example

[0028] Figures 6 to 7 As shown: This invention provides a multi-channel oropharyngeal ventilation device for anesthesiology. Its structure includes a positioning body b1, an overlapping rail b2, a bearing ring b3, a telescopic shaft b4, and a push block b5 newly added to the outer periphery of the middle section of the constant temperature pipe fitting 18. The center of the positioning body b1 is penetrated by the overlapping rail b2, and the edge of the overlapping rail b2 is penetrated by the bearing ring b3. The telescopic shaft b4 is positioned at the edge of the bearing ring b3, and the push block b5 is fixed to the top of the telescopic shaft b4. The push block b5 is set below the fixing groove 17 through the telescopic shaft b4 and the positioning body b1. The telescopic shaft b4 is electrically connected to the control terminal 15 through the power block 16. The positioning body b1 is circular, and the diameter of the bearing ring b3 is larger than the diameter of the overlapping rail b2. There are four sets of telescopic shafts b4 and push blocks b5 arranged in four directions. The positioning body b1 can be adapted to the shape of the component through its circular shape, and then it can be fixed to the middle section of the outer layer of the component through the overlapping rail b2. The bearing ring b3 can cover the edge of the overlapping rail b2 through its large diameter. Then the positions of the telescopic shaft b4 and the push block b5 are determined. The telescopic shaft b4 and the push block b5 can stably push the patient's oropharynx through the four-way fixation.

[0029] The push block b5 includes a connecting end b51, a solid block b52, an overlapping layer b53, and a medical rubber block b54. The connecting end b51 and the solid block b52 are integrated. The top of the solid block b52 is fixedly connected to the medical rubber block b54 through the overlapping layer b53. The solid block b52 is connected to the top of the telescopic shaft b4 through the connecting end b51. The positioning body b1 is set in the middle section of the outer layer of the ventilation tube 4 through the overlapping rail b2. The solid block b52 is arc-shaped, the surface of the overlapping layer b53 is finely polished, and the shape of the medical rubber block b54 is consistent with the shape of the solid block b52. The solid block b52 can be adapted to the shape of the component through its arc shape. The overlapping layer b53 can ensure that the medical rubber block b54 forms a gapless fit with the solid block b52 after being installed through surface polishing. The medical rubber block b54 can be precisely aligned and matched with the solid block b52 through its own arc shape.

[0030] The specific functions and operation procedures of this embodiment are as follows: In this invention, First: The newly added positioning body b1 in the middle section of the outer layer of the constant temperature tube 18 can cover the outer layer of the ventilation tube 4 through the overlapping rail b2. Then, the four sets of telescopic shafts b4 on the bearing ring b3 and the push block b5 can be used in the oropharyngeal region. It uses the insertion position of the ventilation tube 4 to contact the oropharyngeal region. When the oropharynx contracts due to other stimuli, the telescopic shaft b4 will drive the push block b5 to move out slowly through the control of the control end 15. Under the effect of slowly pushing the oropharynx, it can help the patient open the oropharynx, preventing the patient from being unable to control the opening and closing of the oropharynx during anesthesia, and improving the convenience of treatment. Second: The solid block b52 of the push block b5 can be connected to the telescopic shaft b4 through the connecting end b51. Then, the solid block b52 will be stably connected to the medical rubber block b54 using the finely polished overlapping layer b53, avoiding the generation of excessive gaps. Thus, the medical rubber block b54 can directly contact the oropharynx. Its own flexibility can prevent scratches to the oropharyngeal area during the pushing process, improving the safety factor of helping to open the oropharyngeal area.
