Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a drug spraying device for clinical medical use. Background Art

[0002] A drug sprayer is a medical device that sprays drugs in a specific form (such as liquid atomization or aerosol) and delivers them precisely to the target area. It directly applies drugs to lesions (such as the nasal cavity, mouth, and throat), thereby reducing systemic side effects. Compared with oral medication, which relies on blood circulation, drug spraying is more convenient and labor-saving.

[0003] Taking throat spraying as an example, during the spraying process, the patient should sit on a chair, lean forward slightly, lower the head slightly, open the mouth, and make an "ah" sound to expose the throat. Then place the nozzle of the spray device in the front of the patient's mouth, so that it is a certain distance away from the throat, generally 1-2 cm. Then aim at the area that needs spraying and press the start button to spray the medicine on the mucosal surface of the throat. After spraying, in order to ensure the efficacy of the medicine, the patient needs to keep his mouth open for a while so that the medicine can take effect in the throat.

[0004] During the spraying process, since the amount of medicine sprayed each time is fixed, it is difficult to adjust the amount of medicine sprayed according to the patient's condition. For example, the dosage of medicine required by young children is lower than the standard dosage, which affects the treatment effect. In addition, during the spraying process, when the sprayed medicine is continuously directed at the same part, especially when the spraying force is too strong, the friction generated when the medicine is sprayed may cause damage to the throat mucosa, thereby causing pain or inflammation to worsen, affecting the treatment effect.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making any creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 8As shown, this embodiment proposes a medical clinical spray device, including a device housing 1, a liquid storage tank 2 is installed on the upper part of the device housing 1, and also includes a spray pipe 3, a nozzle housing 4, a homogenizing spray component, a liquid pushing component and a quantitative adding component. The spray pipe 3 is fixedly installed inside the device housing 1, and the nozzle housing 4 is fixedly installed at the end of the spray pipe 3. The inner diameter of the nozzle housing 4 is the same as that of the spray pipe 3. The homogenizing spray component is installed inside the nozzle housing 4 for spraying liquid medicine. The homogenizing spray component includes a rotating cover 5, a mist The atomizing nozzle 6, the first bevel gear 7, the second bevel gear 8 and the driving part, the rotating cover 5 is rotatably and sealedly installed inside the nozzle housing 4, the atomizing nozzle 6 is fixed and eccentrically installed on the rotating cover 5, the input end of the atomizing nozzle 6 is inside the nozzle housing 4, the first bevel gear 7 is coaxially fixedly installed on the rotating cover 5, the second bevel gear 8 is rotatably installed inside the nozzle housing 4, the first bevel gear 7 is engaged with the second bevel gear 8, and the driving part is installed inside the nozzle housing 4, for driving the rotating cover 5 to rotate when spraying medicine.

[0024] Specifically, during use, first unscrew the inlet on the top of the liquid storage tank 2, pour the required liquid into the liquid storage tank 2, then cover the lid, take out the required amount of liquid in the liquid storage tank 2 through the quantitative adding component, and then send it to the inside of the spray pipe 3. At this time, the liquid medicine is between the liquid pushing component and the nozzle shell 4 at the end of the spray pipe 3, and then the liquid pushing component is used to push the liquid medicine into the nozzle shell 4. Under the action of the liquid pushing component, the air in the space between the nozzle shell 4 and the liquid pushing component is discharged, and then the patient's affected area can be sprayed.

[0025] Taking the throat spray as an example, first let the patient sit on a chair, lean forward slightly, lower the head slightly, open the mouth to expose the throat, and then put the nozzle shell 4 into the patient's mouth, so that it is a certain distance away from the throat, generally 1-2 cm, and then aim at the part where the spray is required, and push the liquid in the spray tube 3 through the liquid pushing component to make it spray out in the form of water mist through the atomizing nozzle 6. When spraying, the second bevel gear 8 is driven to rotate by the driving part, and the second bevel gear 8 drives the first bevel gear 7 to rotate, and the first bevel gear 7 drives the rotating cover 5 to rotate the nozzle shell. 4 axis is the center of rotation, thereby driving the atomizing nozzle 6 to rotate around the axis of the nozzle housing 4, and as the medicine liquid is sprayed out, the medicine is sprayed on the mucosal surface of the affected part of the throat. By rotating the cover 5 to drive the rotation of the atomizing nozzle 6, when spraying the medicine on the patient's throat, the spraying area can be expanded, and the medicine liquid can be avoided from being continuously directed to the same part for administration, which relieves the patient's discomfort and reduces the irritation to the affected part. After spraying the medicine, in order to ensure the efficacy of the medicine, the patient is also required to keep his mouth open for a period of time so that the medicine can take effect in the throat.

[0026] The above, such as Figure 3 、 Figure 4 As shown, the driving part includes a driving motor 9, a connecting tube 10 and a transmission component 12. The driving motor 9 is fixedly installed inside the device housing 1, and the connecting tube 10 is fixedly installed between the device housing 1 and the nozzle housing 4. A transmission shaft 11 is rotatably installed inside the connecting tube 10, and the transmission shaft 11 is fixedly connected to the output end of the driving motor 9. The transmission component 12 is installed between the transmission shaft 11 and the second bevel gear 8 for transmitting power.

[0027] Specifically, when it is necessary to drive the rotary cover 5 to rotate, the driving motor 9 is turned on, and the driving motor 9 drives the transmission shaft 11 to rotate in the transmission cylinder, thereby driving the second bevel gear 8 to rotate through the setting of the transmission component 12, thereby realizing the rotation of the driving rotary cover 5.

[0028] Among them, the transmission component 12 includes two meshing helical gears, one of which is coaxially fixed on the second helical gear 8, and the other helical gear is coaxially rotatably installed on the connecting cylinder 10 and fixedly connected to the transmission shaft 11. When the driving motor 9 drives the transmission shaft 11 to rotate, the power can be transmitted to the second helical gear 8 through the meshing of the two helical gears.

[0029] like Figure 5 、 Figure 6 As shown, the liquid pushing assembly is installed inside the spray pipe 3, and is used to deliver the liquid to be sprayed to one end of the spray pipe 3 close to the nozzle housing 4, and fill the nozzle housing 4 with the liquid. The liquid pushing assembly includes a fixed frame 13, a liquid pushing cylinder 14, a driving member 16 and a positioning portion. The fixed frame 13 is fixedly installed on one end of the device housing 1 away from the nozzle housing 4, and the liquid pushing cylinder 14 is slidably installed inside the spray pipe 3. The interior of the liquid pushing cylinder 14 includes a liquid pushing area and a sliding area. Two strip protrusions 15 are symmetrically arranged inside the sliding area. The driving member 16 is fixedly installed in the liquid pushing area. The output end of the driving member 16 is fixedly mounted with a first piston 17, which is sealed and slidably matched with the inner wall of the spray pipe 3. The positioning portion is installed inside the liquid pushing cylinder 14 to push the liquid pushing cylinder 14 to move in the spray pipe 3.

[0030] Specifically, after the liquid medicine is sent into the spray tube 3, it is necessary to send the liquid medicine to the inside of the nozzle housing 4. At this time, the adjustment part is adjusted. Through the setting of the adjustment part, the liquid pushing cylinder 14 is driven to move in the spray tube 3, thereby pushing the first piston 17 to move. Under the action of the first piston 17, the liquid medicine is pushed into the nozzle housing 4. The first piston 17 is adapted to the inner diameter of the nozzle housing 4. When spraying, Figure 2 As shown in FIG, the switch on the handle portion at the bottom of the device housing 1 starts the driving member 16 to move, thereby pushing the first piston 17 to move through the driving member 16, thereby pushing the liquid medicine out.

[0031] The driving member 16 is generally configured as an electric cylinder. An external switch is connected to the electric cylinder control box via a terminal block and is directly associated with the control of the electric cylinder, thereby controlling the extension and reset of the electric cylinder by adjusting the switch.

[0032] The above, such as Figure 5 、 Figure 6 As shown, the adjustment portion includes a slide rail 18, an adjustment screw 19 and an adjustment nut 21. Two slide rails 18 are symmetrically and fixedly installed inside the fixed frame 13. The two slide rails 18 are both located inside the liquid pushing cylinder 14. The slide rails 18 slide with the strip protrusion 15. The adjustment screw 19 is rotatably installed on the fixed frame 13. The adjustment screw 19 is located inside the sliding area. The adjustment screw 19 is coaxially arranged with the liquid pushing cylinder 14. A knob 20 is fixedly installed on the end of the adjustment screw 19. A threaded sleeve is provided with an adjustment nut 21 on the adjustment screw 19, and the adjustment nut 21 is fixedly connected to the liquid pushing cylinder 14.

[0033] Specifically, when adjusting the position of the liquid pushing cylinder 14, hold the knob 20 and rotate the knob 20, thereby driving the adjustment screw 19 to rotate, and the adjustment screw 19 pushes the adjustment nut 21 to rotate. At this time, through the cooperation between the slide rail 18 and the strip protrusion 15, since the slide rail 18 is installed on the fixed frame 13, when the liquid pushing cylinder 14 moves, the strip protrusion 15 inside it slides relative to the slide rail 18, thereby maintaining stability during movement.

[0034] like Figure 7 、 Figure 8 As shown, the quantitative addition component is installed inside the liquid storage tank 2, and is used to quantitatively deliver the liquid medicine to the spray pipe 3. The quantitative addition component includes a feeding cylinder 22, a feeding cylinder 23, a first one-way valve 24, a second one-way valve 25, a material taking part and a feeding part. The feeding cylinder 22 is fixedly installed on the device housing 1, and the feeding cylinder 23 is fixedly installed inside the liquid storage tank 2. The feeding cylinder 23 is located in a corner inside the liquid storage tank 2, wherein the side of the feeding cylinder 23 is located outside the liquid storage tank 2, and the side of the feeding cylinder 23 is set to be transparent. The material is bright, the first one-way valve 24 is connected to the bottom of the feeding cylinder 23, and there is a gap between the input end of the first one-way valve 24 and the inner bottom wall of the liquid storage tank 2. The input end of the second one-way valve 25 is connected to a position near the bottom of one side of the feeding cylinder 23, and the output end of the second one-way valve 25 is connected to a position near the middle of one side of the feeding cylinder 22. The material taking part is installed inside the feeding cylinder 23, and is used to quantitatively take out the medicine liquid and send it into the feeding cylinder 22. The feeding part is installed inside the feeding cylinder 22, and is used to send the medicine liquid into the spray pipe 3.

[0035] Specifically, when spraying medicine into the patient's throat, due to the design of the pump head, the amount of medicine sprayed each time is fixed, and it is difficult to adjust the amount of medicine sprayed according to the patient's actual situation. First, if the amount of medicine sprayed each time is too much, it will lead to drug waste, increase treatment costs, and increase the risk of drug side effects. However, if the amount of medicine sprayed is too small, it will affect the treatment effect. Furthermore, when spraying medicine into the throat for young children and elderly patients, the dosage of the medicine needs to be controlled more carefully. In order to ensure good treatment effects, the amount of medicine also needs to be controlled.

[0036] When adding a certain amount of liquid medicine, it is necessary to first confirm that there is liquid medicine in the liquid storage tank 2, and then pull the material taking part upwards, so that the liquid medicine is sucked into the feeding cylinder 23 through the first one-way valve 24 at the bottom of the feeding cylinder 23. Since the side of the feeding cylinder 23 is made of transparent material and a scale is also provided on this side, it is convenient to read the liquid medicine sucked into the feeding cylinder 23. When the liquid medicine reaches the required amount, the material taking part can be pressed downwards. At this time, the first one-way valve 24 is cut off and the second one-way valve 25 is opened. The liquid medicine enters the feeding cylinder 22 under the action of the material taking part, and the second one-way valve 25 is opened. The output end is connected to a position near the middle of one side of the feeding barrel 22, that is, the liquid medicine entering the feeding barrel 22 will first be retained at the bottom of the feeding barrel 22, and the liquid level of the liquid medicine is still some distance away from the feeding part. The bottom of the feeding barrel 22 is set to be conical to gather the liquid medicine. When the liquid medicine in the feeding barrel 22 needs to be fed into the spray pipe 3, the feeding part is pressed down to deliver the liquid medicine to the spray pipe 3. Since the liquid level of the liquid medicine is still some distance away from the feeding part, there is air in this interval. Under the action of this part of air, the possibility of the liquid medicine being retained in the feeding barrel 22 is reduced.

[0037] The above, such as Figure 7 、 Figure 8 As shown, the material taking part includes a connecting rod 26 and a second piston 27. The connecting rod 26 is slidably installed inside the feeding barrel 23. The second piston 27 is fixedly installed at the bottom of the connecting rod 26. The second piston 27 is sealed and slidably matched with the side wall of the feeding barrel 23.

[0038] Specifically, when sucking the liquid medicine, hold and pull the connecting rod 26 upwards, thereby driving the second piston 27 to move until a certain amount of liquid medicine is sucked out, then press the connecting rod 26 downwards until the second piston 27 moves to the inner bottom wall of the feeding barrel 23, and through the setting of the second piston 27, the first one-way valve 24 and the second one-way valve 25 are blocked.

[0039] The above, such as Figure 7 、 Figure 8As shown, the feeding part includes a feeding pipe 28, a control rod 29, a fixed disk 31, a movable disk 32 and a spring 33. The feeding pipe 28 is connected between the spray pipe 3 and the bottom of the feeding barrel 22. The position where the feeding pipe 28 is connected to the spray pipe 3 is located between the first piston 17 and the nozzle housing 4. The control rod 29 is slidably installed inside the feeding barrel 22. The third piston 30 is fixedly installed at the bottom of the control rod 29. The third piston 30 is located on the upper part of the second one-way valve 25. The fixed disk 31 is fixedly installed inside the feeding barrel 22. The bottom of the fixed disk 31 abuts against the third piston 30. The fixed disk 31 slides with the control rod 29. The movable disk 32 is fixedly installed on the control rod 29. A spring 33 is fixedly installed between the fixed disk 31 and the movable disk 32.

[0040] Specifically, when a fixed amount of liquid medicine is delivered to the feed barrel 22 through the second one-way valve 25, the third piston 30 is located above the second one-way valve 25. When the liquid medicine needs to be delivered to the spray pipe 3, the control rod 29 is held and pressed downward to push the third piston 30 to move, thereby delivering the liquid medicine to the spray pipe 3 through the feed pipe 28. During the movement of the control rod 29, the control rod 29 drives the movable disk 32 to move. At this time, under the action of the fixed disk 31, the spring 33 is compressed. After the medicine is delivered to the spray pipe 3, under the action of the spring 33, the spring 33 releases the pressure, and the control rod 29 is reset by the setting of the movable disk 32, which is more labor-saving.

[0041] like Figure 2 、 Figure 4 As shown, in order to prevent the patient's tongue from affecting the homogenizing spray assembly, a bite block 34 is also included. The bite block 34 is set on the spray tube 3, and a mounting bracket 35 is rotatably mounted on the bottom of the bite block 34. A groove is set inside the mounting bracket 35.

[0042] Specifically, when the nozzle shell 4 at the end of the spray tube 3 needs to be delivered to the patient's mouth, before that, since the distance between the lips and the throat of different patients is different, the position of the bite block 34 is first adjusted according to the patient's condition to ensure that the atomizing nozzle 6 is at a certain distance from the affected part of the patient's throat to avoid contact with the throat, and then the tongue depressor 36 is installed in the groove of the mounting bracket 35. At this time, the tongue depressor 36 is located at the lower part of the nozzle shell 4. When the nozzle shell 4 at the end of the spray tube 3 is delivered to the patient's mouth, the patient bites the bottom of one end of the mounting bracket 35 away from the atomizing nozzle 6, so that the tongue depressor 36 presses the tongue through the lever action to prevent the tongue from pressing against the atomizing nozzle 6 and affecting the drug administration, and makes the affected part better exposed to the spraying position.

[0043] It should be added that the tongue depressor 36 is disposable, and the length of the tongue depressor 36 is determined according to the patient's condition.

[0044] The working principle or usage process of this application is as follows: During use, first unscrew the inlet on the top of the liquid storage tank 2, pour the required medicine into the liquid storage tank 2, and then cover the lid. When sucking the medicine, hold and pull the connecting rod 26 upwards, thereby driving the second piston 27 to move, so that the medicine is sucked into the feeding cylinder 23 through the first one-way valve 24 at the bottom of the feeding cylinder 23. Since the side of the feeding cylinder 23 is made of transparent material and a scale is also provided on this side, it is convenient to read the medicine sucked into the feeding cylinder 23. When a certain amount of medicine is sucked out, the connecting rod 26 can be pressed down. At this time, the first one-way valve 24 is cut off and the second one-way valve 25 is opened. The medicine enters the feeding cylinder 22 under the action of the material taking part until the second piston 27 moves to the inner bottom wall of the feeding cylinder 23, and the first one-way valve 24 and the second one-way valve 25 are blocked by the setting of the second piston 27, and the medicine can be added to the spray pipe 3.

[0045] When a certain amount of liquid medicine is sent to the feeding barrel 22 through the second one-way valve 25, since the third piston 30 is located on the upper part of the second one-way valve 25, the output end of the second one-way valve 25 is connected to a position near the middle of one side of the feeding barrel 22, that is, the liquid medicine entering the feeding barrel 22 will first be retained at the bottom of the feeding barrel 22, and the liquid level of the liquid medicine is still a distance away from the feeding part, that is, there is air in this interval. Under the action of this part of air, the possibility of the liquid medicine being retained in the feeding barrel 22 is reduced. The bottom of the feeding barrel 22 is set to be conical to gather the liquid medicine. When the feeding barrel 22 needs to be opened, When the liquid medicine in the medicine spray pipe 3 is fed into the medicine spray pipe 3, hold and press the control rod 29 downward, thereby pushing the third piston 30 to move, and thus feeding the liquid medicine into the medicine spray pipe 3 through the feeding pipe 28. At this time, the liquid medicine is between the first piston 17 and the nozzle housing 4 at the end of the medicine spray pipe 3. During the movement of the control rod 29, the control rod 29 drives the movable disk 32 to move. At this time, under the action of the fixed disk 31, the spring 33 is compressed. When the medicine is fed into the medicine spray pipe 3, under the action of the spring 33, the spring 33 releases the pressure, and the control rod 29 is reset by the setting of the movable disk 32.

[0046] Then push the medicine into the inside of the nozzle housing 4. At this time, hold the knob 20 and rotate it, thereby driving the adjusting screw 19 to rotate, and the adjusting screw 19 pushes the adjusting nut 21 to rotate. At this time, through the cooperation of the slide rail 18 and the strip protrusion 15, since the slide rail 18 is installed on the fixed frame 13, when the liquid pushing cylinder 14 moves, the strip protrusion 15 inside it slides relative to the slide rail 18 until the first piston 17 is pushed to the specified position. Under the action of the first piston 17, the medicine is pushed into the nozzle housing 4. The first piston 17 is adapted to the inner diameter of the nozzle housing 4. At this time, the air in the space between the nozzle housing 4 and the liquid pushing component is discharged, and then the patient's affected area can be sprayed with medicine.

[0047] At this time, the position of the bite block 34 is adjusted according to the patient's condition to ensure that the atomizing nozzle 6 is at a certain distance from the affected part of the patient's throat to avoid contact with the throat. Then the tongue depressor 36 is installed in the groove of the mounting frame 35. At this time, the tongue depressor 36 is located at the lower part of the nozzle shell 4. Then the nozzle shell 4 is sent into the patient's mouth so that it is at a certain distance from the throat. At this time, the patient bites the bottom of one end of the mounting frame 35 away from the atomizing nozzle 6, so that the tongue depressor 36 is pressed on the tongue through the lever action to avoid the tongue pressing against the atomizing nozzle 6 to affect the drug administration, and to make the affected part better exposed to the spraying position. Then, aim at the part where the medicine needs to be sprayed, start the drive part 16 to push the first piston 17 to move, so that it is sprayed out in the form of water mist through the atomizing nozzle 6.

[0048] When spraying medicine, turn on the driving motor 9, and the driving motor 9 drives the transmission shaft 11 to rotate in the transmission cylinder, thereby driving the second bevel gear 8 to rotate through the setting of the transmission component 12, and the second bevel gear 8 drives the first bevel gear 7 to rotate, and the first bevel gear 7 drives the rotating cover 5 to rotate with the axis of the nozzle shell 4 as the center, thereby driving the atomizing nozzle 6 to rotate around the axis of the nozzle shell 4. As the medicine liquid is sprayed out, the medicine is sprayed on the mucosal surface of the affected part of the throat. By rotating the cover 5 to drive the rotation of the atomizing nozzle 6, when spraying the patient's throat, the spraying area can be expanded, and the medicine liquid can be avoided from being continuously administered to the same part, which relieves the patient's discomfort and reduces the irritation to the affected part. After spraying, in order to ensure the efficacy of the medicine, the patient is also required to keep his mouth open for a period of time so that the medicine can take effect in the throat.
