Description

Technical Field

[0001] The invention belongs to the technical field of medical devices and relates to a coupling agent auxiliary device for ultrasonic examination. Background Art

[0002] During ultrasound examinations, medical staff need to apply coupling agent to the patient's skin because ultrasound waves have poor transmission efficiency in air. The coupling agent fills the gaps in the patient's skin so that the ultrasound probe can fit the patient's skin completely, thus avoiding the influence of air leakage and forming a clear image. In addition, the coupling agent helps the probe slide on the skin, reducing the discomfort caused by friction, and making the doctor's operation more flexible and comfortable.

[0003] The prior art also has the following deficiencies:

[0004] During an existing ultrasound examination, the patient needs to lie on the examination bed, exposing the examination area. The medical staff directly squeezes the coupling agent on the patient's area and spreads it evenly using an ultrasonic probe. This method of applying the coupling agent is the simplest, but the problem is that the patient's body sensation is extremely poor. Since the overall temperature of the coupling agent is significantly lower than the patient's body temperature, the patient's skin will be irritated and feel uncomfortable. In addition, since the coupling agents in hospitals are generally purchased in large-capacity bottles, it is very inconvenient to take them when used, and the time for heating the coupling agent inside in a water bath will also increase accordingly. Therefore, there is a need for a coupling agent auxiliary device for ultrasound examinations that can adapt to large-capacity coupling agent bottles and facilitate the application of the coupling agent inside.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] The following is combined with Figures 1 to 13 The specific embodiments of the present invention are described in further detail.

[0036] Depend on Figures 1 to 13As shown, the present invention includes a placement barrel 1 for accommodating a coupling agent bottle. To facilitate the application of the coupling agent and facilitate operation by medical personnel, a plurality of adapter plates 2 for adapting to coupling agent bottles of different thicknesses are provided inside the placement barrel 1. A connecting tube is connected to the lower side of the placement barrel 1. An elastic tube 4 is connected to the end of the connecting tube away from the placement barrel 1. An application brush 5 is connected to the end of the elastic tube 4. A heating mechanism 6 is provided inside the application brush 5. A broken line groove 7 is provided on the outside of the placement barrel 1. The middle portion of the elastic tube 4 is wound around the broken line groove 7. A fixing mechanism 8 is provided on the outside of the placement barrel 1, and a pressurizing mechanism 9 is provided inside the placement barrel 1.

[0037] During use, a coupling agent bottle can be placed inside the placement tube 1. Currently, hospitals mostly use 500ml medical ultrasonic coupling agent. The bottle can be directly inverted and placed in the placement tube 1. At this time, under the action of the adapter plate 2, the bottle can be ensured to be centered so that the bottle mouth can be connected to the connecting tube. After that, the pressure-applying mechanism 9 pressurizes the interior of the bottle, and the coupling agent flows out of the application brush 5 after passing through the connecting tube and the elastic tube 4. During this process, the heating mechanism 6 inside the application brush 5 can heat the coupling agent to reduce the discomfort caused by the low temperature of the coupling agent. The elastic tube 4 is stored in the folded rope groove 7. The fixing mechanism 8 is used to fix the device in a suitable position on the examination bed, making it convenient for medical staff to use.

[0038] In addition, through the pressurizing mechanism 9, gas can be filled into the interior of the bottle to pressurize the interior and discharge the coupling agent. Alternatively, a pipeline can be directly connected to pump the coupling agent in other containers directly into the coupling agent bottle placed inside the tube 1 through a peristaltic pump, which facilitates the operation of medical staff and makes the use scenarios of the device more diverse.

[0039] Furthermore, in order to facilitate medical personnel in replacing the coupling agent bottle, a tapered sleeve 10 is fixedly connected to the lower side of the placement cylinder 1, a connecting sleeve 11 is fixedly connected to the lower side of the tapered sleeve 10, a pressing block 12 is connected to the internal thread of the connecting sleeve 11, and a tapered pad 13 is fixedly connected to the side of the connecting tube close to the placement cylinder 1, and the tapered pad 13 is arranged between the pressing block 12 and the tapered sleeve 10;

[0040] During use, when connecting the connecting pipe and the tapered sleeve 10, the clamping block 12 can be directly tightened. Through the threaded connection between the clamping block 12 and the connecting sleeve 11, the tapered pad 13 is pressed against the outside of the tapered sleeve 10, thereby completing the connection and sealing between the tapered sleeve 10 and the connecting pipe.

[0041] Further, in order to be able to press the coupling agent bottle body tightly in the inside of the placing cylinder 1, each adaptive plate 2 is fixedly connected with the placing cylinder 1 near one side of the placing cylinder 1, and the adaptive plate 2 is obliquely arranged in the inside of the placing cylinder 1, and a spring sheet 14 is arranged between each adaptive plate 2 and the inner side wall of the placing cylinder 1;

[0042] It should be noted that the adaptive plate 2 is made of rubber structure and can be elastically deformed, and under the action of the spring sheet 14, it can adapt to the use of bottle bodies of coupling agents with different thicknesses.

[0043] Further, in order to facilitate the fixing of the coupling agent bottle body, an adaptive sleeve 15 is threadedly connected to the upper side of the placing cylinder 1, a plurality of adaptive rods 16 are fixedly connected in the inside of the adaptive sleeve 15, an end cover 17 is slidably connected in the inside of the adaptive sleeve 15, a plurality of adaptive holes 18 are formed in the end cover 17, each adaptive hole 18 is slidably connected with the corresponding adaptive rod 16 in the inside, an adaptive spring 19 is arranged on the upper side of the end cover 17, and a rubber ring 20 is arranged in the middle of the end cover 17;

[0044] In use, by arranging the adaptive spring 19, the end cover 17 can be pressed down to tightly press the coupling agent bottle body during the threaded connection of the adaptive sleeve 15 and the placing cylinder 1, so as to fix the bottle body of the coupling agent and the placing cylinder 1.

[0045] Further, in order to enable the elastic tube 4 to be automatically stored, a plurality of elastic wires 21 are embedded in the inside of the elastic tube 4;

[0046] In use, by arranging the elastic wire 21, the elastic tube 4 is consistent with the shape of the broken line rope groove 7 in a natural state, facilitating the storage thereof.

[0047] Further, in order to reduce the discomfort of the patient when applying the coupling agent, the warming mechanism 6 comprises a warming catheter 22 and an electric heating wire 23, the electric heating wire 23 is sleeved on the outside of the warming catheter 22, the warming catheter 22 and the electric heating wire 23 are embedded in the inside of the applicator brush 5, the upper end of the warming catheter 22 is communicated with the elastic tube 4, a dispersion groove 24 communicated with the warming catheter 22 is formed in the inside of the applicator brush 5, and a plurality of dispersion holes 25 are communicated with the lower side of the dispersion groove 24; the electric heating wire 23 is prior art, such as iron-chromium-aluminum, nickel-chromium electric heating alloy, and the two ends are connected with a power supply, which will not be described here;

[0048] In use, when the coupling agent flows in the inside of the warming catheter 22, under the action of the electric heating wire 23, the coupling agent can be heated to reduce the discomfort of the patient, and through the dispersion groove 24 and the dispersion holes 25, the coupling agent can flow out of the plurality of dispersion holes 25, facilitating the use of medical staff.

[0049] Furthermore, in order to facilitate the use of the device, the fixing mechanism 8 includes a rotating sleeve 26, a fixed sleeve 27 and a connecting plate 28. The rotating sleeve 26 is clamped with the tapered sleeve 10, and the connecting plate 28 is fixedly connected to the outside of the placement tube 1. The fixed sleeve 27 is arranged between the rotating sleeve 26 and the connecting plate 28. The upper and lower sides of the fixed sleeve 27 are rotatably connected to the connecting plate 28 and the rotating sleeve 26 through bearings respectively. A accommodating ring 29 is provided on the side of the rotating sleeve 26 close to the fixed sleeve 27. A coil spring 30 is provided inside the accommodating ring 29. The two ends of 30 are fixedly connected to the receiving ring 29 and the fixed sleeve 27 respectively. The side wall of the fixed sleeve 27 is provided with a through groove 31 for passing the elastic tube 4. The outer wall of the fixed sleeve 27 is fixedly connected with a fixing clip 32 for fixing the fixed sleeve 27 to the examination bed. The fixing clip 32 includes a fixing rod and a seat tube clamp. The two ends of the fixing rod are fixedly connected to the outer wall of the fixed sleeve 27 and the outer wall of the seat tube clamp respectively. The seat tube clamp is a prior art that can fix the device to the bed leg or bed guard by friction. It will not be described in detail here.

[0050] During use, the fixed sleeve 27 can be fixed to the appropriate position of the bed leg or bed guard or other tubular fixed structure of the examination bed through the seat tube clamp. At this time, the fixed sleeve 27 is fixed relative to the bed. In the process of pulling the elastic tube 4, the placement tube 1 and the tapered sleeve 10 will be driven to rotate. At this time, since the tapered sleeve 10 and the rotating sleeve 26 are connected by a snap buckle, the rotating sleeve 26 can be driven to rotate together with the tapered sleeve 10. Therefore, in the process of pulling the elastic tube 4, the rotating sleeve 26 will rotate relative to the fixed sleeve 27, thereby storing force in the coil spring 30. When the elastic tube 4 is relaxed, the placement tube 1 will be driven to rotate under the action of the coil spring 30, so that the elastic tube 4 rebounds and is stored in the folding rope groove 7.

[0051] Furthermore, in order to facilitate the operation of medical personnel, the pressurizing mechanism 9 includes a pressurizing sleeve 33, a connecting pipe and an air filling pipe 35. The upper side of the connecting pipe is rotatably connected to the air filling pipe 35, and the lower side of the connecting pipe is rotatably connected to the pressurizing sleeve 33. Two pressurizing holes 36 are provided inside the pressurizing sleeve 33, and a pressurizing channel 37 is provided inside the connecting pipe. The air filling pipe 35 is connected to the pressurizing holes 36 through the pressurizing channel 37. The end of the air filling pipe 35 away from the connecting pipe is connected to an air pump or a peristaltic pump.

[0052] It should be noted that the air pump is a micro positive and negative pressure air pump, which is a prior art, such as the basic small sampling air pump model D50, which will not be described in detail here. The outside of the smear brush 5 is provided with a start-stop switch of the air pump, which is connected to the air pump via communication to control the start and stop time of the air pump; the peristaltic pump is a prior art, and the coupling agent in other containers can be pumped into the pressurized sleeve 33 through the pipeline and the peristaltic pump, which is convenient for use; the air pump is fixedly connected to the outside of the fixed sleeve 27 when in use;

[0053] During use, the pressurizing sleeve 33 penetrates into the couplant bottle through the bottom of the couplant bottle. At this time, the rubber ring 20 can compress the gap between the couplant bottle and the pressurizing sleeve 33 to ensure its sealing performance.

[0054] During use, after starting the air pump, the air can be pumped into the coupling agent bottle through the gas filling pipe 35, the connecting tube, the pressurizing sleeve 33, and the pressurizing hole 36, thereby pressurizing the coupling agent bottle. Since the coupling agent bottle is in an inverted state, the coupling agent will flow downward into the interior of the connecting tube under the action of its own weight.

[0055] Furthermore, in order to facilitate the operation of medical personnel, an elastic block 38 is fixedly connected to the outer side of the pressurizing sleeve 33, and two limiting notches 39 are provided on the side of the connecting tube close to the elastic block 38. The elastic block 38 and the limiting notches 39 cooperate with each other to form a structure for limiting the rotation of the connecting tube relative to the pressurizing sleeve 33. The side wall of the fixing buckle 32 is rotatably connected to a connecting bent rod. Specifically, the side wall of the fixing rod is rotatably connected to a connecting bent rod, and the side of the connecting bent rod close to the pressurizing sleeve 33 is fixedly connected to a limiting buckle. A limiting block is fixedly connected to the outer side of the limiting sleeve, and the limiting block and the limiting buckle cooperate with each other to form a structure for the pressurizing sleeve 33 to rotate relative to the placement sleeve.

[0056] The side wall of the pressurizing sleeve 33 is provided with two receiving grooves 40, and a connecting rod 41 is rotatably connected to the interior of each receiving groove 40. A scraper plate 42 is rotatably connected to the end of the connecting rod 41 away from the receiving groove 40. A movable block 43 that can slide up and down is provided inside the pressurizing sleeve 33, and a sliding rod 44 is fixedly connected to the side of the movable block 43 close to each connecting rod 41. A sliding groove 45 is provided in the middle of each connecting rod 41, and each sliding rod 44 is slidably connected to the interior of the sliding groove 45. The interior of the pressurizing sleeve 33 is further provided with two sliding holes 46, and the interior of each sliding hole 46 is slidably connected to a sliding sleeve 47. The side wall of the pressurizing channel 37 is provided with two extension channels 48, and each extension channel 48 is communicated with the corresponding sliding hole 46;

[0057] When in use, the communication relationship between the air filling pipe 35 and the pressurized hole 36 and the sliding hole 46 can be adjusted by rotating the connecting pipe. When the coupling agent is normally used, the air filling pipe 35 is connected to the pressurized hole 36 through the pressurized channel 37. When the connecting rod 41 needs to be unfolded, the connecting pipe can be rotated, and the elastic block 38 is made to cooperate with another limiting notch 39 under the action of the elastic block 38. At this time, the air filling pipe 35 is connected to the sliding hole 46 through the extension channel 48. After starting the air pump, the interior of the sliding hole 46 will be pressurized, and then the moving block 46 will be pushed together through the two sliding sleeves 47. 43 moves. During the movement of the moving block 43, each sliding rod 44 slides inside the sliding groove 45, thereby pushing the connecting rod 41 to rotate and expand relative to the pressurizing sleeve 33. At this time, the scraping plate 42 will fit with the inner wall of the coupling agent bottle. At this time, when the elastic tube 4 is pulled again, under the action of the limit block and the limit buckle, the pressurizing sleeve 33 will not rotate relative to the placement tube 1, while the elastic tube 4 will pull the placement tube 1 to rotate, thereby causing the pressurizing sleeve 33 and the coupling agent bottle to rotate relative to each other, and the residual coupling agent inside the coupling agent bottle is scraped off by the scraping plate 42, reducing material waste.

[0058] When the present invention is used, first, a coupling agent bottle can be placed inside the placement tube 1. Currently, hospitals mostly use 500ml medical ultrasonic coupling agent. The bottle body can be directly inverted and placed in the placement tube 1. At this time, under the action of the adapter plate 2, the bottle body can be ensured to be centered, so that the bottle mouth can be connected to the connecting tube. After that, the inside of the bottle body is pressurized by the pressurizing mechanism 9, and the coupling agent flows out from the application brush 5 after passing through the connecting tube and the elastic tube 4. During this process, the heating mechanism 6 inside the application brush 5 can heat the coupling agent to reduce the discomfort caused by the low temperature of the coupling agent. The elastic tube 4 is stored in the folding rope groove 7, and the fixing mechanism 8 is used to fix the device in a suitable position on the examination bed, which is convenient for medical staff to use.

[0059] The present invention has a novel structure, an ingenious concept, and is simple and convenient to operate. The present invention effectively facilitates the operation of medical staff to replace the coupling agent bottle, reduces the discomfort of patients when applying the coupling agent, facilitates the application of the coupling agent by medical staff, facilitates the operation of medical staff, and reduces the waste of coupling agent.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
