Description

Technical Field

[0001] The invention relates to the technical field of laryngoscopes, in particular to a medication device for pediatric throat. Background Art

[0002] The role of the video laryngoscope in throat examination includes clear examination of the throat, diagnosis of throat diseases, and guidance of clinical endotracheal intubation operations. The video laryngoscope consists of a handheld part, a cannula, and a camera at the end of the cannula. Based on the ability of the video laryngoscope to clearly examine the throat, a drug delivery structure is provided at the end of the cannula to directly cover the lesion site with drugs, facilitating rapid regression of the lesion site.

[0003] However, the drug delivery structure designed at the end of the existing video laryngoscope has many disadvantages, such as:

[0004] The "electronic laryngoscope" disclosed in the patent number "CN105662326B" includes a drug injection hole on the rear sealing end, through which the drug delivery catheter is connected to the sputum channel of the hollow tube, or the drug delivery catheter passes through the drug injection hole and extends to the periphery of the camera module; in this embodiment, the specific position of the drug injection hole is not recorded, but combined with common sense, the drug injection hole can be designed on the end face or the side, and in actual operation: the drug injection hole designed on the side will not be convenient for the camera mechanism to observe whether the drug is accurately sprayed to the lesion site, thereby failing to achieve the expected therapeutic effect; the drug injection hole designed on the end face will inevitably increase the range of the drug so that the sprayed drug can enter the shooting range of the camera mechanism, but the internal structure of the throat is complex and close to the trachea. Excessive drug spraying range will have certain potential hazards, such as drug splashing to other locations, causing physiological reactions, which will undoubtedly increase the risk during the operation.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0040] Combination Figure 1-Figure 16 A pediatric throat medication device comprises a handheld portion 10, a cannula 11, and a tip mechanism 20 mounted at the end of the cannula 11 for photographing and medication, wherein the tip mechanism 20 comprises a jacket 30, and a camera unit 40 and a medication spraying mechanism 50 are mounted inside the jacket 30;

[0041] One side of the outer jacket 30 is provided with an inclined surface A31;

[0042] The camera unit 40 includes a mounting seat A41, a camera module 42, and a lighting unit. The mounting seat A41 is embedded in the inner side of the outer jacket 30 near the protruding portion of the inclined surface A31. The camera module 42 and the lighting unit are mounted on the surface of the mounting seat A41. The camera mirror surface of the camera module 42 is coplanar with the inclined surface A31, and the camera range of the camera module 42 tends to be on the concave side of the inclined surface A31.

[0043] The spraying mechanism 50 includes a mounting seat B51, a transparent plate 52 and a spraying assembly 53. A liquid pipe 56 for supplying liquid to the spraying assembly 53 is connected to one side of the mounting seat B51. The spraying assembly 53 is embedded in the surface of the mounting seat B51. The spraying assembly 53 sprays medicine obliquely downward and enters the camera range of the camera module 42. The mounting seat B51 is provided with a cooperative assembly 57 for controlling the transparent plate 52 to rotate and open on its surface. The opened transparent plate 52 covers one side of the spraying assembly 53.

[0044] In the conventional drug spraying treatment using the drug delivery structure at the end of the visual laryngoscope, there are problems such as blind spots in observation and too large a coverage area of ​​the drug spraying. In this embodiment, the tilted shooting module 42 is used to make the shooting range of the shooting module 42 tilted to one side, but still able to cover the circumferential inner wall of the human nose and throat cavity, such as the attached Figure 4 In the figure, the dotted line on one side of the shooting module 42 is shown, and when the transparent plate 52 is closed on the surface of the mounting seat B51, the end face of the outer sleeve 30 is ensured to be closed, and when it is opened, the spray component 53 is exposed to spray medicine at an angle. This method can reduce the range of drug spraying, and the transparent plate 52 opened on one side of the spray component 53 can also block the outside of the drug spraying range to avoid drug splashing and cause physiological reactions.

[0045] Furthermore, one side of the mounting seat A41 is coplanar with the inclined surface A31, and one side of the mounting seat B51 is provided with an inclined surface B511 coplanar with the inclined surface A31, and the transparent plate 52 is embedded in the surface of the mounting seat B51. This design makes the end surface of the end mechanism 20 flat and without protrusions, which is convenient for inserting the cannula 11 through the nasal and throat cavities. In addition, one side of the mounting seat A41 is coplanar with the inclined surface A31, which facilitates the reduction of obstacles when the shooting module 42 is shooting, and the inclined surface B511 facilitates the increase of the space under the spray component 53 and the increase of the coverage area of ​​the medicine.

[0046] Furthermore, the lighting unit includes a second lighting module 44 parallel to the inclined plane A31, and a first lighting module 43 perpendicular to the propulsion direction of the end mechanism 20. A cover body 45 is provided on the outside of the first lighting module 43 and the second lighting module 44. The first lighting module 43 illuminates the propulsion direction of the shooting module 42, and the second lighting module 44 illuminates the shooting area of ​​the shooting module 42, so as to clearly observe the spray component 53 covering the lesion position with medicine.

[0047] In the previous embodiment: the lower side of the mounting seat B51 is also provided with a phlegm removing assembly 54 for clearing phlegm in the spraying area of ​​the spraying assembly 53, the phlegm removing assembly 54 comprises a first phlegm collecting groove 512 opened inwardly from the lower side of the mounting seat B51, and a second phlegm collecting groove 513 inclined to one side from the lower side of the first phlegm collecting groove 512, an air inlet 542 is opened at the bottom of the side of the second phlegm collecting groove 513, a phlegm suction port 541 is also opened on the side surface of the inclined surface B511 and above the first phlegm collecting groove 512, and the outer cover 30 is provided with an inclined groove opening 32 inwardly at the lower edge of the first phlegm collecting groove 512;

[0048] During the application of medicine to the lesion, there is a situation where sputum covers the lesion, which will cause the medicine sprayed by the spray assembly 53 to be unable to directly act on the lesion, thereby affecting the treatment. The present embodiment is as follows: the end mechanism 20 is pushed toward the lesion, and the inclined groove 32, the first sputum collecting groove 512, and the second sputum collecting groove 513 are combined to form an open mouth for sputum to gather toward the air inlet 542. The sputum gathers at the position of the air inlet 542 and is sucked away. The setting of the sputum suction port 541 is used to add sterile air to the open mouth where sputum gathers, so as to prevent the suction force of the air inlet 542 from sucking away part of the air in the open mouth, resulting in local negative pressure. The tissue wall at the position of the end mechanism 20 in the laryngeal cavity, which is easily caused by the negative pressure, contracts, causing discomfort.

[0049] Further, a reflector 522 is rotatably embedded in the outer surface of the transparent plate 52, and an embedding groove 523 for embedding the reflector 522 is provided on the surface of the transparent plate 52. A pull wire 524 is eccentrically connected to one end of the connecting shaft between the reflector 522 and the transparent plate 52, and one end of the pull wire 524 is fixedly connected to the surface of the inclined surface B511. When the transparent plate 52 is rotated and opened on the surface of the inclined surface B511, the pull wire 524 rotates and pulls up the reflector 522 on the surface of the transparent plate 52, and the shooting module 42 observes the area where the first sputum collecting groove 512 is located through the reflector 522. When the reflector 522 is opened on the transparent plate 52, the shooting module 42 can observe the spraying area corresponding to the spraying assembly 53 through the embedded groove 523, and when the first sputum collecting groove 512 is pushed over the lesion area and the sputum covering the surface of the lesion is pushed into the inner side of the first sputum collecting groove 512, the shooting module 42 can observe the sputum being absorbed in the first sputum collecting groove 512 through the refraction of the reflector 522, so as to accurately grasp the time to pull back the coat 30 so that the spraying area of ​​the transparent plate 52 is aimed at the lesion again.

[0050] In the previous embodiment: a connector 55 is connected between the liquid passage 56 and the medicine spraying assembly 53, and one side of the connector 55 is provided with: a drug delivery tube 551 connected to the medicine spraying assembly 53, a sputum suction tube 552 connected to the air inlet 542, and an air outlet tube 553 connected to the sputum suction port 541. A one-way valve for one-way connection to the medicine spraying assembly 53 is provided in the drug delivery tube 551, and a butt joint tube A554 connected to the liquid passage 56 is provided on the other side. A first partition plate 555 and a second partition plate 556 for dividing the cavity into three channels A are provided in the butt joint tube A554 cavity. The three channels A are respectively connected to the drug delivery tube 551, the sputum suction tube 552, and the air outlet tube 553. A first diaphragm 561 and a second diaphragm 562 for dividing the cavity into three channels B are provided on the inner wall of the liquid passage tube 56. The first diaphragm 561 is sealedly connected to the first partition plate 555, and the second diaphragm 562 is sealedly connected to the second partition plate 556.

[0051] The liquid passing tube 56 is connected to the hand-held part 10 through the insertion tube 11, and one end is also connected to a docking tube B58. The docking tube B58 has the same structure as the docking tube A554 and is connected to the liquid passing tube 56 in the same way. The side surface of the docking tube B58 is respectively opened with a drug passing port 581 connected to the drug administration tube 551, an air suction port 582, a sputum discharge port 583 connected to the sputum suction tube 552, and an air supply port 584 connected to the air outlet pipe 553 through the liquid passing tube 56.

[0052] The medicine port 581 is externally connected to a structure for supplying medicine through a metering pump, the air suction port 582 is externally connected to a negative pressure pump, the sputum discharge port 583 is externally connected to a liquid suction pump, and the air supply port 584 is externally connected to a pressurized pump for providing sterile air. In response to the need for the cannula 11 to pass through the nose and throat cavities of the human body, the liquid supply tube 56 can simultaneously meet the needs of supplying medicine, supplying air, and sputum discharge, without the need for multiple catheters, greatly reducing the cross-sectional diameter of the cannula 11 and reducing the discomfort of the patient. The operation method is as follows: when the cannula 11 passes through the nose and throat cavities of the human body, the cannula 11 is connected to the air suction port 582, and the sputum discharge port 583 is externally connected to a liquid suction pump, and the air supply port 584 is externally connected to a pressurized pump for providing sterile air. When the laryngeal lesion site is observed to be covered with sputum through the shooting module 42, the cannula 11 is continuously pushed to make the oblique groove 32 scrape the lesion site. It should be noted here that the lesions in the throat are often manifested as congestion, swelling, and edema. A single slight scraping will not aggravate the condition. The outer surface of the oblique groove 32 can be provided with a flexible material to reduce foreign matter and discomfort, and the sputum is concentrated in the first sputum collecting groove 512. Then, the negative pressure pump connected to the suction port 582 is started first to promote the first diaphragm inside the liquid tube 56 to 561 is attached to the inner wall of one side and the negative pressure of the negative pressure pump is maintained, so that the second diaphragm 562 is in a taut state to separate the inner cavity of the liquid tube 56, which makes the channel cross-section for transmitting sterile air and sputum in the liquid tube 56 larger, and increases the transmission speed. Then, the liquid extraction pump connected to the sputum discharge port 583 and the pressure pump connected to the air supply port 584 are started again, so that the air inlet 542 sucks the sputum collected in the first sputum collecting groove 512, and the sputum suction port 541 discharges sterile air to replenish it. The first sputum collecting groove 512 is then observed through the reflector 522. After the sputum inside the first sputum collecting groove 512 is completely sucked away and discharged through the sputum discharge port 583, the negative pressure pump connected to the air suction port 582 is closed, and liquid medicine is injected through the drug outlet 581. The liquid medicine will squeeze the first diaphragm 561 to one side, thereby increasing the cross-section of the channel for transmitting liquid medicine in the liquid outlet pipe 56. Finally, the liquid medicine is sprayed out from the spray assembly 53 to cover the lesion site.

[0053] In the previous embodiment: the medicine spraying assembly 53 includes a rotating medicine spraying barrel 531, and a plurality of different spray heads 5311 are arranged on the circumference of the surface of the medicine spraying barrel 531. A directional liquid inlet barrel 532 is sealed and rotatably connected to one side of the medicine spraying barrel 531. A curved cover 5321 is fixedly provided on one side of the directional liquid inlet barrel 532 and is inserted into the inner side of the medicine spraying barrel 531. The liquid outlet 5322 provided on the surface of the curved cover 5321 corresponds to the spraying angle of the medicine spraying assembly 53. One side of the directional liquid inlet barrel 532 is fixedly connected to the drug delivery tube 551 through a connector 533.

[0054] Different nozzles 5311 spray the medicine in different modes, such as umbrella shape, direct spray shape, atomization shape, etc., so that according to the characteristics of the lesion, the appropriate nozzle 5311 can be selected and rotated to the position corresponding to the liquid outlet 5322, and the medicine injected into the arc cover 5321 can be sprayed through the nozzle 5311. This method provides a variety of different options for adapting to the treatment of lesions of different areas and characteristics.

[0055] In the previous embodiment: the cooperative component 57 includes a fixed rail 571 fixedly assembled in the mounting seat B51, a U-shaped movable frame 572 slidably mounted is connected to the lower side of the fixed rail 571, a rack 573 rotatably connected is provided at the lower side of the U-shaped movable frame 572, a one-way one-way tooth B574 is provided at the lower side of the rack 573, a first limit block 5711 for limiting the movement of the U-shaped movable frame 572 and a tension spring 578 for pulling it by elastic force are provided on the lower surface of the fixed rail 571, a coaxial rotating shaft B5312 is fixedly provided on one side of the spray barrel 531, a positioning component 5313 and a one-way bearing 5314 are respectively provided on the surface of the rotating shaft B5312, and a one-way tooth A5315 cooperating with the one-way tooth B574 is also circumferentially arranged;

[0056] (As attached Fig.12 As shown in the figure, when the U-shaped movable frame 572 is pulled to the right, the rack 573 pulls the rotating shaft B5312 to rotate clockwise through the one-way gear A5315, so as to achieve the purpose of adjusting and rotating the nozzle 5311. When the U-shaped movable frame 572 is moved to the left, the one-way gear B574 slides on the one-way gear A5315, and does not drive the rotating shaft B5312 to rotate counterclockwise, and the one-way bearing 5314 also limits the rotating shaft B5312 to rotate counterclockwise, so as to achieve the rotation of the adjusting rotating shaft B5312. The rack 573 is rotatably connected to the U-shaped movable frame 572, preferably through a retaining spring hinge, so as to promote the elastic rotation trend of the rack 573 downward, so that the one-way gear B574 and the one-way gear A5315 fit closely.

[0057] A movable block 575 is slidably installed on the side of the fixed rail 571, and a rotating lever 576 is rotatably installed on the side of the movable block 575. The lower side of the rotating lever 576 is movably connected to the U-shaped movable frame 572. A clutch line 577 for pulling it is connected to one side of the movable block 575. The transparent plate 52 is rotatably connected to the mounting seat B51 through a rotating seat 521 on the back. One side of the rotating seat 521 is provided with a retaining spring that elastically drives the rotating seat 521 to rotate, so as to cause the transparent plate 52 to be close to the surface of the inclined surface B511. A rotating shaft A525 is fixedly connected to the coaxial side of the rotating seat 521, and a pull rope 526 is connected to the arc surface of the rotating shaft A525. One end of the pull rope 526 is connected to the upper end of the rotating lever 576. A second limit block 5712 is provided on the upper side of the fixed rail 571 to limit the upper end position of the rotating lever 576. One end of the clutch line 577 passes through the cannula 11 to reach the handheld part 10, and is connected to the output end of the electric telescopic rod arranged in the cannula 11. The pulling distance of the clutch line 577 is precisely controlled by an electric telescopic rod;

[0058] Combined with Fig.12The elastic potential energy of the tension spring 578 is greater than the clip spring provided on one side of the rotating seat 521. When the movable block 575 is pulled to move rightward by the clutch line 577, the upper end of the movable block 575 moves first, thereby pulling the rotating shaft A525 to rotate to a preset angle through the pull rope 526. At the same time, the upper end of the rotating lever 576 is limited by the second limit block 5712. This implementation realizes the transparent plate 52 being rotated and opened from the side of the inclined surface B511.

[0059] When the above operation continues, the movable block 575 is pulled to the right by the clutch line 577. Since the upper end of the rotating lever 576 is limited by the second limit block 5712, the lower end of the rotating lever 576 will swing to the right, thereby pushing the U-shaped movable frame 572 to move to the right. The rack 573 moving to the right can pull the rotating shaft B5312 to rotate, so as to achieve the purpose of adjusting and rotating the nozzle 5311. Repeating the process of pulling the clutch line 577 for the second time can achieve multiple adjustments of the nozzle 5311.

[0060] Through the above operation, the transparent plate 52 and the spray cartridge 531 can be controlled separately via a clutch line 577, thereby once again reducing the cross-sectional diameter required for the cannula 11.

[0061] Furthermore, the positioning component 5313 includes an inner fixing ring 53132 fixedly sleeved on the surface of the rotating shaft B5312, a plurality of arc-shaped spring pieces 53133 are arranged circumferentially on the surface of the inner fixing ring 53132, a positioning circular frame 53131 is sleeved on the outer side of the plurality of arc-shaped spring pieces 53133, an arc-shaped sliding groove corresponding to the arc-shaped spring pieces 53133 is arranged on the inner wall of the positioning circular frame 53131, and the positioning circular frame 53131 is fixedly installed in the mounting seat B51, and the plurality of arc-shaped spring pieces 53133 and the plurality of nozzles 531 1, when the rotating shaft B5312 is driven to rotate by the rack 573, the arc-shaped spring piece 53133 will slide on the inner wall of the positioning circular frame 53131. When the middle part of the arc-shaped spring piece 53133 is squeezed and deformed and slides over the peak of the inner wall of the positioning circular frame 53131, it will automatically slide to the bottom of the newly entered arc-shaped groove, so that the nozzle 5311 on the surface of the spray cartridge 531 will be automatically positioned to the side of the liquid outlet 5322, which ensures the accuracy of the alignment of the nozzle 5311 and the liquid outlet 5322.

[0062] Working principle: first push the end mechanism 20 through the nasal cavity through the cannula 11 and advance it into the laryngeal cavity, and at the same time observe the inner wall of the laryngeal cavity according to the video picture fed back by the camera unit 40 to find the lesion site. After finding the lesion site, rotate the cannula 11 so that the oblique slot 32 of the jacket 30 is aligned with the lesion site. Then, if the lesion site is not covered with sputum and is exposed, continue to push the end mechanism 20 to make the lesion point be located within the spray range of the nozzle 5311, then pull the clutch line 577 for the first time to make the transparent plate 52 rotate and open, and select the appropriate nozzle 5311 according to the characteristics and area of ​​the lesion by pulling the clutch line 577 again, and then start the metering pump so that the nozzle 5311 sprays the medicine onto the lesion site;

[0063] If the lesion is covered with sputum, the cannula 11 is pushed to make the inclined slot 32 scrape the lesion to collect the sputum in the first sputum collecting groove 512, and then the negative pressure pump connected to the air suction port 582 is started to make the first diaphragm 561 inside the liquid tube 56 fit to the inner wall on one side, and the negative pressure of the negative pressure pump is maintained to make the second diaphragm 562 in a taut state to separate the inner cavity of the liquid tube 56, which makes the channel cross-section used for transmitting sterile air and sputum in the liquid tube 56 larger, and increases the transmission speed, and then it is started again and connected to the sputum discharge port 583. The suction pump and the pressure pump connected to the air supply port 584 enable the air inlet 542 to suck the sputum collected in the first sputum collecting groove 512, and the sputum suction port 541 discharges sterile air to replenish the first sputum collecting groove 512. Then, the inside of the first sputum collecting groove 512 is observed through the reflector 522. After the sputum in the first sputum collecting groove 512 is sucked away and discharged through the sputum discharge port 583, the negative pressure pump connected to the air suction port 582 is closed, and liquid medicine is injected through the medicine port 581. The liquid medicine is sprayed from the nozzle 5311 to cover the lesion site.
