Detailed ways

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.

A throat sprayer for anesthesia that can effectively reduce oral discomfort, as shown in Figures 1, 2, 3 and 5, includes a medicine storage bin 1, an inner liquid storage bin 10 installed inside the medicine storage bin 1, a catheter body 20 installed at the front end of the medicine storage bin 1, and a nozzle 23 installed on the front end side wall of the catheter body 20. A discharge port 8 is opened upward at the bottom of the medicine storage bin 1, and a discharge cover 9 is installed at the bottom of the discharge port 8 through a thread. Since the liquid medicine is stored in the inner liquid storage bin 10 and the remaining liquid medicine needs to be poured out after use, making the opening of the discharge port 8 larger is more convenient for discharging the liquid medicine, and after the discharge cover 9 is opened from the discharge port 8 through a threaded manner, the larger opening makes it more convenient for medical staff to sterilize and clean the interior of the inner liquid storage bin 10, and an introduction port 7 is fixed on the upper half of the front end of the medicine storage bin 1, and the discharge port 8 is connected with the inner liquid storage bin 10 and the introduction port 7. A handle body 2 is fixed to the upper half of the end surface of the medicine storage bin 1 away from the introduction port 7, and there is a certain angle between the entire handle body 2 and the medicine storage bin 1. When in use, medical staff need to hold the handle body 2, and a button area 3 is provided on the upper half of the surface of the handle body 2, and the button area 3 is operated by the thumb. A battery 4 is provided on the surface of the medicine storage bin 1 and below the handle body 2, and a bin cover 5 is installed on the port of the battery 4 through bolt closure. The battery 4 is electrically connected to the button area 3, and the device is powered by the battery 4. The battery 4 is closed between the bin cover 5 and the medicine storage bin 1, and the bin cover 5 can be opened when the battery 4 needs to be replaced. A base body 6 is fixedly installed at the bottom of the medicine storage bin 1 and on both sides of the discharge cover 9, and an electric pump 24 is installed through the front end of the medicine storage bin 1 and below the introduction port 7, and the electric pump 24 is connected to the inner liquid storage bin 10.

As shown in Figures 1 and 3, an oral support mechanism is arranged above the medicine storage bin 1, and the oral support mechanism includes a support connecting rod 16, a support pad body 18 and a reinforcement body 19. The support connecting rod 16 is inserted into the inner side of the slot body of the storage slot 12, and the support pad body 18 is fixed to the front end of the support connecting rod 16. The support pad body 18 adopts a U-shaped structure, and the reinforcement body 19 is columnar and fixed to the U-shaped inner wall of the support pad body 18. A rod shaft 17 is installed at one end of the support connecting rod 16 away from the support pad body 18, and the rod shaft 17 is rotatably connected to the support connecting rod 16. The support pad body 18 is symmetrically distributed about the rod shaft 17, and the outer wall of the support pad body 18 is wrapped and fitted with a rubber sleeve layer 15. The entire discharge port 8 is U-shaped and needs to be placed directly in the patient's oral cavity and located at the position of the teeth when in use. The support pad body 18 of the U-shaped structure further assists the structure on both sides of the oral teeth, and the overall distribution is symmetrical. The two groups of support pad bodies 18 are respectively located on both sides of the support connecting rod 16, and the middle parts of the two groups of support connecting rods 16 are in an open state, so that the entire oral cavity has a large set of operable spaces, which makes it convenient to insert the catheter body 20 into the oral cavity. In order to improve the comfort of tooth occlusion, a rubber sleeve layer 15 is covered on the surface of the support pad body 18. The rubber sleeve layer 15 made of rubber material can provide a certain buffer during the patient's tooth occlusion process, thereby protecting the teeth.

As shown in Figures 1, 3 and 4, a storage groove 12 for accommodating an oral support mechanism is downwardly opened on the upper end surface of the medicine storage bin 1. The upper end side wall of the medicine storage bin 1 is rotatably connected to a groove body shaft 13, and the outer wall of the shaft body of the groove body shaft 13 is fixedly fitted with a groove body closing plate 14. The storage groove 12 adopts a recessed structure, and the shape is consistent with the folded support pad body 18 combined with the support connecting rod 16. Before use, in order to ensure the hygiene and safety of the entire support connecting rod 16 and the support pad body 18, it is generally necessary to seal the support pad body 18 and install it before use. The folded support connecting rod 16 is vertically inserted into the inner side of the groove of the storage groove 12 so that the arc-shaped end of the storage groove 12 can accommodate the arc-shaped support pad body 18. The long strip groove of the storage groove 12 can be used to accommodate two groups of support connecting rods 16.

As shown in FIG1 , the end of the electric pump 24 away from the drug storage bin 1 is connected to the reinforcement body 19 by a thread, and the end of the reinforcement body 19 away from the electric pump 24 is connected to the rear port of the catheter body 20 by a thread, and the front port of the catheter body 20 is installed with a plug 21 by a thread, and the plug 21 adopts a truncated cone structure of silicone. Since the sprayer needs to contact the patient's mouth, it has high requirements for its hygiene and safety. After each patient uses the sprayer to apply medicine, the equipment generally needs to be cleaned. In order to facilitate sterilization, a group of reinforcement bodies 19 connected by threads are designed at the connection between the catheter body 20 and the electric pump 24. After using the catheter body 20 once, it can be continued to be used by removing the catheter body 20 and replacing it with another group of catheter bodies 20. In this way, the catheter body 20 that is in direct contact with the patient is more convenient to disassemble quickly, which can increase the number of single uses of the equipment and reduce the frequency of replacement.

As shown in Figures 1 and 6, a spray slot 22 is provided inwardly on the front end side wall of the catheter body 20, and the spray slot 22 is a V-shaped inward annular structure. The nozzle 23 is fixed to the side wall of the slot 22. The spray slot 22 is provided with two groups, and the two groups of nozzles 23 are relatively distributed. The angle between the orientation angle of the two groups of nozzles 23 and the outer wall of the catheter body 20 is 30°-45°. A glass plate 11 is installed on the side wall of the medicine storage bin 1. The nozzles 23 are designed relatively so that the liquid medicine sprayed by the nozzles 23 is sprayed obliquely and has an intersection. In this way, the irritation of the liquid medicine sprayed into the throat is less, and the air retained in the catheter body 20 before the liquid medicine is sprayed can also offset part of the impact force, thereby reducing the irritation to the throat.

As shown in Figures 1, 7 and 8, the side wall of the groove body of the reinforcement body 19 is fixed with an adjustment bin body 27, and the inner side of the adjustment bin body 27 is provided with a drive adjustment mechanism, the inner side of the groove body of the reinforcement body 19 is provided with a slider connector 30, and the side wall of the reinforcement body 19 away from the drive adjustment mechanism is provided with a limited slide groove 26, and the side wall of the slider connector 30 located in the limited slide groove 26 is provided with a stopper 35 slidably connected with the limited slide groove 26, and the drive adjustment mechanism includes an adjustment column shaft 28, a meshing toothed disc 29, and a sliding tooth groove 31. The adjusting column shaft 28 is rotatably connected to the bottom of the adjusting bin body 27, the meshing toothed disc 29 is annularly distributed on the outer wall of the adjusting column shaft 28, the sliding toothed groove 31 is opened on the side wall of the slider connector 30 away from the stop block 35, the sliding toothed disc 34 is fixed to the inner wall of the slot body of the sliding toothed groove 31, and the sliding toothed disc 34 is distributed along the long end surface spacing of the slot body of the sliding toothed groove 31, the meshing toothed disc 29 is meshed with the sliding toothed disc 34, and the top of the adjusting column shaft 28 is downwardly opened with a slot, reinforcing the slot body of the body 19 A limited fixing square hole 25 is provided at the bottom, and the limited fixing square holes 25 are distributed along the long end surface spacing of the bottom of the reinforcement body 19. A limited position plug hole 32 is provided inside the slider connector 30, and the opening size of the limited position plug hole 32 is consistent with the limited position fixing square hole 25. A limited position plug block 33 is installed on the top of the slider connector 30 by plugging with the limited position plug hole 32, and the limited position plug block 33 adopts a U-shaped structure. The end of the slider connector 30 away from the reinforcement body 19 is fixedly connected to the inner wall of the support pad body 18. Since the support pad body 18 is made of aluminum alloy or other metals with a certain deformation ability, when it is clamped between the upper and lower teeth, the bending angle of the support pad body 18 can be adjusted by driving the adjustment mechanism. When the bending angle of the support pad body 18 is large, the oral cavity of the patient supported by the support pad body 18 is small. When the bending angle of the support pad body 18 is small, the entire support pad body 18 has a large opening angle to the patient's oral cavity. Such a large oral opening angle is suitable for older patients or, conversely, for younger patients, so that the device can be used for people of different age groups.

Working principle: For this type of sprayer, when in use, the battery 4 needs to be installed on the inner side of the compartment cover 5, and the entire device is powered by the compartment cover 5. Then the medical staff will pour the prepared medicine into the interior of the internal liquid storage tank 10 through the inlet 7, and keep the bottom to the discharge port 8 closed with the discharge cover 9, and then hold the handle rod body 2 with one hand, and naturally fit the thumb on the key area 3, and connect one end of the catheter body 20 with the front end of the reinforcement body 19 through a thread, and connect the rear end of the plug 21 with the front end of the catheter body 20 through a thread, and then use the rotation structure of the groove body shaft 13 to unfold the groove body closing plate 14 closed above the storage groove 12, and then take out the supporting connecting rod 16 and the supporting pad body 18 attached to the inner side of the storage groove 12, and use the rotation structure of the rod body shaft 17 to unfold the supporting connecting rod 16 and the supporting pad body 18 in the folded state, and then use the outer side of the two groups of rubber sleeve layers 15 to connect a group of disposable rubber The rubber sleeve layer 15 is then placed on the upper and lower teeth position of the patient's oral cavity, so that the support pads 18 on both sides support the upper and lower teeth and the oral cavity. When the bending angle of the support pad 18 needs to be adjusted, the limiting plug 33 of the U-shaped structure is pulled out from the inside of the limiting plug hole 32, and then a flat knife is used to insert it into the flat interface position of the upper end of the adjusting column shaft 28, and then the flat knife is rotated to rotate the adjusting column shaft 28. After the adjusting column shaft 28 rotates, the meshing toothed disc 29 fixedly connected on the surface drives the meshing sliding toothed disc 34 to move, and the sliding toothed disc 34 is fixed to the slider connector 30, so that the entire slider connector 30 can be driven to move back and forth at the inner position of the reinforcement body 19. By shortening the overall distance between the reinforcement body 19 and the slider connector 30, the bending of the support pad body 18 becomes larger. Conversely, by lengthening the overall distance between the reinforcement body 19 and the slider connector 30, the bending of the support pad body 18 becomes smaller.

Then the medical staff can use the tongue depressor to depress the patient's tongue, insert the plug 21 into the throat of the oral cavity, and push it downward into the throat to push the plug 21 to the specified depth, and then operate the key area 3 with the thumb to start the electric pump 24 electrically connected to the key area 3, extract the medicine inside the internal liquid storage tank 10 and introduce it into the catheter body 20. Before the medicine is sprayed out from the nozzle 23, a part of the space is retained inside the catheter body 20. Since the nozzles 23 are relatively distributed and the sprays have an intersection, the sprayed air produces a certain offsetting effect at the intersection, so that the air has less stimulation to the patient's throat, and then the medicine is sprayed from the nozzle 23 to the throat.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
