Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a respiratory tract clearing device for pediatrics. Background Art

[0002] At present, in order to keep the patient's respiratory tract unobstructed and conduct normal gas exchange, medical staff mostly need to use a suction device to remove sputum, foreign matter, etc. in the respiratory tract. The suction device is mainly composed of a main unit, a suction tube, a sputum storage bottle or a sputum storage bag, etc. It uses the negative pressure principle to generate negative pressure through an electric motor or a manual pump to suck the sputum out of the patient's respiratory tract.

[0003] In the prior art, a Chinese patent (patent publication number: CN115814178B) provides a pediatric respiratory tract clearing device, including a shell, a liquid suction component and a drug delivery component. One end of the shell is provided with a first adapter, a four-way tube, a third adapter and a Y-type hose. A micro negative pressure pump is provided inside the shell, a liquid suction channel and a drug delivery channel are provided in the Y-type hose, a liquid suction connector and a drug delivery connector are provided on the third adapter, and a tank body, a second adapter, a first quick-release mechanism and a second quick-release mechanism are provided in the liquid suction component and the drug delivery component. When cleaning the patient's respiratory tract, the present invention can adjust the angle and depth of the Y-type hose at will, so that the respiratory tract can be cleaned more thoroughly. At the same time, the drug delivery component can deliver the drug solution into the patient's respiratory tract through the drug delivery channel to achieve a better therapeutic effect. The quick-release mechanism is provided to make the assembly of the present invention faster and more convenient. If the liquid storage tank needs to be cleaned or replaced, the quick-release mechanism can make the replacement of the liquid storage tank more convenient.

[0004] Although the above-mentioned equipment has the advantages of simple and fast operation and diverse functions, the suction device only relies on the positive and negative pressures generated by the negative pressure pump to achieve the function of delivering medicine and suctioning sputum. There is no clear order between delivering medicine and suctioning sputum. When the device is delivering medicine, expectorant drugs are easily affected by the negative pressure generated by the suction tube, which will cause the drugs to be unevenly distributed in the patient's respiratory tract or be sucked out of the respiratory tract, making the sputum too viscous and difficult to suction out, causing the patient to feel uncomfortable. When suctioning sputum, the device will still continuously deliver drugs to the patient's respiratory tract. These drugs will affect the suction effect of the device, resulting in more sputum remaining in the patient's respiratory tract, and the problem of breathing difficulties cannot be solved.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the negative pressure pump inhales external air through the surface hole of input tube one and delivers it to the corresponding storage tank, delivers the internal medicine to the patient's respiratory tract, dilutes the sputum, and facilitates the device to suck out the sputum. Then the medical staff detents the rotating push plate to push the two control sleeves, and the gas inside the output tube one will be discharged through the surface hole, driving the device to stop delivering medicine. The sealed input tube one can draw the diluted sputum into another storage tank through the input tube two. The medical staff can control the device to deliver medicine and draw sputum according to the patient's actual condition, thereby improving the efficiency and treatment effect of sputum drawing, and preventing the poor expectoration effect, resulting in difficulty in sputum drawing, and increasing the pain of the patient when drawing sputum.

[0019] 2. In the present invention, medical staff can insert two support plates into the patient's mouth, and then rotate the adjusting wheel to drive the slider to move through the bidirectional screw, thereby increasing the distance between the two support plates and stretching the patient's mouth. This not only allows medical staff to observe the patient's respiratory tract more clearly and improve the suction effect, but also prevents the patient from closing his mouth due to tension and discomfort during suction, thereby affecting the suction effect.

[0020] 3. When the present invention is in use, when medical staff need to add medicine or pour out sputum, they only need to find the corresponding storage tank, and then press the card block 2 back into the installation groove in turn. At this time, the compressed compression spring 1 will drive the card block 1 to be pulled out from the storage tank, which is convenient for medical staff to remove the storage tank for medicine addition, cleaning or replacement, thereby effectively reducing the time for removing and installing the storage tank, thereby improving work efficiency and allowing them to spend more time on the treatment and care of patients.

There is a ventilation groove 214, a fixing rod 215 is fixedly installed between the inner surface walls of the ventilation groove 214, and a rotating push plate 216 is provided on the outer wall of the fixing rod 215. A spring fixing seat 217 is fixedly installed on one side of the outer wall of the rotating push plate 216, and a hook spring 218 is wound around the outer wall of the spring fixing seat 217, and a spring fixing seat 219 is wound around the outer wall of the hook spring 218. A positioning plate 220 is fixedly installed on one side of the outer wall of the spring fixing seat 219, and the inner surface walls of the ventilation groove 214 are fixedly connected to the outer wall of the positioning plate 220, the outer wall of the output pipe 204 is provided with a control sleeve 221, and the outer wall of the input pipe 209 is provided with a control sleeve 222. The control sleeve 222 is provided on the outer wall of the input pipe 209. A connecting plate 223 is fixedly installed on the outer wall of 22, and the outer wall of the connecting plate 223 is fixedly connected to the outer wall of the control sleeve 221, two tension springs 224 are fixedly installed on one side of the inner wall of the ventilation groove 214, and connecting pieces 225 are fixedly installed on one side of the outer walls of the two tension springs 224, and the outer wall of one of the two connecting pieces 225 is fixedly connected to the outer wall of the control sleeve 221, and the outer wall of the other of the two connecting pieces 225 is fixedly installed with a control sleeve 222, the input end of the input pipe 212 is fixedly connected to the connecting pipe 1 226, the output end of the output pipe 207 is fixedly connected to the connecting pipe 227, and the outer wall of the connecting pipe 1 226 is adhered to the outer wall of the connecting pipe 2 227.

[0039] In this embodiment, when extracting sputum from the patient's respiratory tract, the medical staff first inserts the two support plates 115 into the patient's mouth. At this time, the two silicone pads 102 are attached to the patient's face. Since the silicone pad 102 is relatively soft, it can prevent the hard mounting platform 101 or other devices from contacting the patient's skin, causing pain or injury to the patient. The honeycomb structure on the silicone pad 102 can improve the air permeability of the silicone pad 102, and prevent the temperature of the patient's skin that is in contact with the silicone pad 102 from rising due to airtightness. Then the medical staff wraps the Velcro hook surface band 103 and the Velcro velvet surface band 104 around the patient's head respectively, and makes the Velcro velvet surface band 104 stick to the surface of the Velcro hook surface band 103 behind the patient's head. The connection of the two straps can fix the position of the device to prevent the device from falling and injuring the patient or losing the opening effect. After the device is fixed, the rotating adjustment wheel 110 drives the bidirectional screw rod 109 to rotate, so that the two connecting seats 111 and the pulley 112 start to rotate. When the pulley 112 rotates, the connecting belt 113 drives another bidirectional screw rod 109 and the connecting seat 111 to rotate under the action of friction. When the four connecting seats 111 move, the four groups of sliders 108 are also driven to move together. The four guide rails 107 will cause the four groups of sliders 108 and the four connecting seats 111 to move in a straight line, and gradually open the patient's mouth through the two support plates 115, so that medical staff can observe the patient's respiratory tract more clearly, thereby improving the suction effect. The two opened support plates 115 can also prevent the patient from closing his mouth due to discomfort during suction, biting the suction tube, affecting the suction effect, and even causing damage to the suction tube.

[0040] Embodiment 2

[0041] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Fig.13As shown, the opening mechanism 1 includes a mounting platform 101, two silicone pads 102 are adhered to one side of the outer wall of the mounting platform 101, a Velcro hook surface band 103 is adhered to one side of the outer wall of the mounting platform 101, a Velcro velvet surface band 104 is adhered to one side of the outer wall of the mounting platform 101, two protective covers 105 are fixedly installed on one side of the outer wall of the mounting platform 101, a group of mounting holes 106 are opened on the outer walls of the two protective covers 105, a group of guide rails 107 are fixedly installed on the bottom of the inner walls of the two protective covers 105, two groups of sliders 108 are movably sleeved on the outer walls of the two groups of guide rails 107, and a bidirectional screw rod 109 is movably inserted between the inner walls of the two groups of mounting holes 106. An adjusting wheel 110 is fixedly installed on one side of the outer wall of one of the two bidirectional screw rods 109, the outer walls of the two bidirectional screw rods 109 are threadedly connected to two connecting seats 111, and the outer walls of the four sets of sliders 108 are fixedly connected to the outer walls of the connecting seats 111, and the inner walls of the two protective covers 105 are movably embedded with connecting seats 111, and pulleys 112 are fixedly installed on one side of the outer walls of the two bidirectional screw rods 109, and a connecting belt 113 is movably sleeved between the outer walls of the two pulleys 112, and a mounting hole 114 is opened on one side of the outer wall of the mounting platform 101, and a support plate 115 is fixedly installed between the outer walls of every two of the four connecting seats 111.

[0042] In this embodiment, the medical staff can first insert the connecting tube 1 226 and the connecting tube 2 227 into the patient's respiratory tract and start the negative pressure pump 203. At this time, the negative pressure pump 203 will extract the air inside the input tube 1 209, so that a negative pressure is formed inside. The outside air will continuously enter through the multiple holes on the outer wall of the input tube 1 209 under the action of pressure. The air extracted by the negative pressure pump 203 will be continuously transported to the inside of the output tube 1 204 and enter the corresponding storage tank 304 through the one-way valve 1 205. The storage tank 304 stores relevant drugs. The one-way valve 1 205 can prevent the drugs from flowing back through the output tube 1 204, thereby causing damage to the relevant device. When the gas enters the storage tank 304, the drugs inside the storage tank 304 will be under pressure. Under the action of the one-way valve 208, the medicine enters the output tube 207. The one-way valve 208 can prevent external pollutants from entering the medicine and causing the medicine to deteriorate. At the same time, both one-way valves require a certain pressure to open, which can prevent the medicine from flowing out when the device is not in use, causing medicine waste. Then the medicine enters the patient's respiratory tract through the connecting tube 227, diluting the relevant sputum, making it easier to be sucked out by the sputum extraction device, thereby improving the sputum extraction effect. After the sputum dilution is completed, the medical staff can detent the rotating push plate 216. When the rotating push plate 216 rotates, the spring fixing seat 217 pulls the hook spring 218. The hook spring 218 can reset the rotating push plate 216 without external force, thereby facilitating multiple uses of the device. When rotating, the top protrusion will push the connecting plate 223 to start moving forward, driving the control sleeve 1 221 and the control sleeve 2 222 to move forward together. The control sleeve 1 221 and the control sleeve 2 222 drive the two connecting pieces 225 to pull the two tension springs 224. The two tension springs 224 facilitate the reset of the control sleeve 1 221 and the control sleeve 2 222. When the control sleeve 1 221 moves forward, the multiple holes at the rear end will overlap with the holes on the surface of the output tube 1 204, causing the output tube 1 204 to start leaking. When the control sleeve 222 slides on the surface of the input tube 1 209, the holes opened at the front end will be staggered with the holes on the surface of the input tube 1 209. The sealed rear end starts to move forward to seal the corresponding holes, so that the input tube 1 209 is in a sealed state, and the negative pressure pump 203 works. When the negative pressure input tube 209 is in the state of lack of external air supplement, the air inside the corresponding storage tank 304 will be extracted through the one-way valve 210. The one-way valve 210 can prevent sputum from entering the input tube 209, causing leakage of viruses and bacteria. The gas extracted by the negative pressure pump 203 will be transported to the output tube 204. The air leaks through the holes on the surface of the output tube 204, and the medicine cannot be transported again. Due to the negative pressure generated inside the input tube 209, the air inside the corresponding storage tank 304 and the connecting tube 226 begins to flow to the negative pressure pump 203. At this time, the connecting tube 226 will extract the sputum inside the patient's respiratory tract. The one-way valve 213 can prevent the sputum from flowing back into the respiratory tract, causing cross contamination and affecting the efficiency of sputum suction.The device can be controlled by medical staff to freely choose the steps of delivering medicine and drawing sputum, which not only improves the flexibility, accuracy and efficiency of the device, but also avoids the simultaneous delivery of medicine and drawing sputum, which results in the inability of the medicine to dilute the sputum, increasing the difficulty of drawing sputum and the pain of the patient.

[0045] In this embodiment, when the medical staff needs to remove the two storage tanks 304, they first touch the two card blocks 2 310 at the same time with their hands, and then squeeze the two card blocks 2 310 hard, so that the card block 2 310 begins to squeeze the compression spring 2 309, so that it moves to the inside of the installation groove 308. When the card block 2 310 completely enters the inside of the installation groove 308, the compression spring 1 306 begins to reset, driving the card block 1 307 to rise and be pulled out from the quick release hole 305. The medical staff pulls out four card blocks 1 307 in succession in the same way, and then the storage tank 304 can be removed from the inside of the top cover 301. The storage tank 304 is easy and quick to remove and install, which can improve the work efficiency of medical staff and reduce the downtime of the device.

[0046] The working principle of the whole mechanism is as follows: when the medical staff needs to extract the sputum in the patient's respiratory tract, they can first insert the two closed support plates 115 into the patient's oral cavity and keep the two soft silicone pads 102 always in contact with the patient's cheeks. The medical staff then wraps the Velcro hook surface band 103 and the Velcro velvet surface band 104 around the patient's head respectively, so that the Velcro velvet surface band 104 is attached to the surface of the Velcro hook surface band 103, and fixes the relevant opening structure through the two Velcro strips to prevent the opening structure from falling due to the swinging of the patient's head. After the medical staff rotates the adjusting wheel 110, it will drive the bidirectional screw rod 109 to start rotating between the inner surface walls of a group of mounting holes 106. When the bidirectional screw rod 109 is driven to rotate, the outer wall 106 is rotated. The pulley 112 fixedly installed on the side starts to rotate in the same direction, and the connecting belt 113 sleeved on the outer wall of the pulley 112 and the part in contact with the pulley 112 begin to move due to the friction force, and this friction force is further transmitted to the other pulley 112 through the belt, so that the corresponding pulley 112 drives another bidirectional screw rod 109 to rotate. During the rotation of the two bidirectional screw rods 109, the surface threads will cause the four connecting seats 111 to move together, and the four connecting seats 111 will then drive the four groups of sliders 108 to slide on the surfaces of the four groups of guide rails 107. At the same time, the four groups of sliders 108 cooperate with the guide rails 107 to limit the four connecting seats 111, making it impossible to rotate and can only do linear motion. When the four connecting seats 111 move , the two support plates 115 begin to move away from each other, stretching the patient's mouth open. After the medical staff sees that the patient's mouth is open, they can hold the handheld shell 201 and move the handheld shell 201 forward, driving the two connecting tubes to move forward inside the second installation hole 114, pushing the connecting tube 1 226 and the connecting tube 2 227 into the patient's respiratory tract, and then the medical staff starts the negative pressure pump 203. The negative pressure pump 203 can inhale external air through the multiple holes on the outer wall of the input tube 1 209 and transport the air to the inside of the output tube 1 204. The air can enter a storage tank 304 through the one-way valve 1 205, so that the internal pressure of the corresponding storage tank 304 continues to increase, and the medicine will rise through the one-way valve 2 208 under the action of pressure and enter the output As the medicine continues to move forward inside the second tube 207, it will enter the sputum in the patient's respiratory tract through the second connecting tube 227 to dilute the sputum. When the sputum is diluted to an appropriate degree, the medical staff will detent the rotating push plate 216 to drive the rotating push plate 216 to rotate on the surface of the fixed rod 215. At this time, the spring fixing seat 217 on the outer wall side moves together, pulling the hook spring 218 to start stretching. When the rotating push plate 216 moves, the top protrusion starts to move to the left, contacts the connecting plate 223, and pushes the connecting plate 223 to start moving forward. The connecting plate 223 makes the control sleeve 1 221 and the control sleeve 2 222 fixedly installed on the outer wall slide on the surfaces of the two pipes. When the control sleeve 1 221 moves forward on the surface of the output tube 1 204,The multiple holes opened at the rear end of the control sleeve 221 will overlap with the holes on the surface of the output tube 204, causing the output tube 204 to be in a non-sealed state. When the control sleeve 222 slides on the surface of the input tube 209, the front end with the holes will be offset from the surface of the input tube 209, and the rear end sealing sleeve will cover the corresponding hole surface, thereby sealing the input tube 209. Since the outside air can no longer enter through the holes on the surface of the input tube 209, the negative pressure pump 203 started at this time causes negative pressure inside the input tube 209, and the air inside the other storage tank 304 is extracted and transported to the inside of the output tube 204. At this time, since the output tube 204 is in a non-sealed state, the corresponding air will pass through the output tube 204. The holes on the surface leak to the outside. Since negative pressure is generated inside the input tube 1 209, negative pressure will also be formed inside the other storage tank 304. The sputum inside the patient's respiratory tract will be drawn into the storage tank 304 through the connecting tube 1 226 and the input tube 2 212. When the medicine inside the two storage tanks 304 is exhausted and needs to be added, or when there is too much sputum and needs to be cleaned, the medical staff only needs to press the card block 2 310 at the same time, so that the card block 2 310 starts to squeeze the compression spring 2 309 and enters the installation groove 308. The compression spring 1 306 squeezed by the card block 1 307 starts to reset, thereby driving the card block 1 307 to be pulled out from the quick release hole 305, so that the medical staff can easily and quickly remove the storage tank 304.
