Description

Technical Field

[0001] This utility model belongs to the technical field of respiratory patient care equipment, and in particular relates to a suction device with an easy-to-disassemble and assemble sputum collection cup. Background Technology

[0002] The human body relies on normal breathing to complete gas exchange, and sputum will continuously be produced in the respiratory tract. For patients with respiratory diseases, airway secretions will increase abnormally. Excessive sputum can easily block the airway, affect normal ventilation, and may also cause various complications. These patients cannot clear sputum smoothly on their own and need to use a professional sputum suction device to clear sputum. The sputum suction device usually relies on a negative pressure generator to generate negative pressure, which is applied to the patient's airway through the connecting tube to smoothly suction out the sputum and collect it in the sputum collection cup, ensuring that the patient's breathing is unobstructed.

[0003] However, existing suction devices are not convenient for securing the sputum collection cup during use. When moving the patient and the suction device, there will be a large amount of shaking, causing the center of gravity of the sputum collection cup to shift, which may cause it to detach from the connecting structure and result in sputum leakage. Utility Model Content

[0004] The purpose of this invention is to provide a sputum suction device with an easy-to-assemble and disassemble sputum collection cup. By setting up an assembly and disassembly part, the invention solves the problem that existing sputum suction devices are not easy to fix during use, and when the patient and the suction device are moved, there will be a large amount of shaking, which will cause the center of gravity of the sputum collection cup to shift, and thus it will fall off the connecting structure, causing sputum leakage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a suction device for easy assembly and disassembly of a sputum collection cup, comprising a negative pressure generator, and further comprising: an assembly / disassembly part installed on the left side of the negative pressure generator; a sealing part located on the left side of the negative pressure generator; the assembly / disassembly part includes a fixing component installed on the left side of the negative pressure generator; and a locking component located outside the negative pressure generator; the fixing component includes a connecting block fixedly connected to the left side of the negative pressure generator, a limiting groove being formed at the top of the connecting block, a slider being slidably connected to the inner wall of the connecting block, two spring telescopic rods being fixedly connected to the inner wall of the slider, the right sides of the two spring telescopic rods being fixedly connected to the connecting block, a locking block being provided in the limiting groove, a cup holder being fixedly connected to the left side of the locking block, a sputum collection cup being fixedly connected to the inner wall of the cup holder, the limiting groove being a T-shaped groove extending to the outside of the connecting block on the left, and the left side of the slider extending into the limiting groove.

[0006] Furthermore, the sealing portion includes a flow assembly installed on the top of the sputum collection cup; and a sealing assembly disposed on the sputum collection cup.

[0007] Furthermore, the locking assembly includes a handle 1 hinged to the front side of the connecting block, a spring fixedly connected to the inner wall of the handle 1, the rear side of the spring fixedly connected to the connecting block, a locking block 2 fixedly connected to the rear side of the handle 1, a limiting component provided inside the connecting block, the locking block 2 being a trapezoidal thin block, the limiting component including a limiting groove 2 opened on the front side of the slider, a limiting groove 3 opened on the front side of the connecting block, the locking block 2 being adapted to the limiting groove 3 and the limiting groove 2.

[0008] Furthermore, the circulation component includes a cup lid disposed above the sputum collection cup. The inner wall of the cup lid is provided with a connecting tube one, and a filter plate is fixedly connected to the inner wall of the connecting tube one. The cup lid is provided with a connecting member and has two through holes. The connecting tube one is made of rubber and is slightly larger than the inner diameter of the hole on the cup lid. The filter plate is used to block sputum from entering the connecting tube one and to ensure normal air circulation. The connecting member includes a connecting tube two disposed inside the connecting tube one, and a connecting tube three disposed inside the cup lid. Both the connecting tube two and the connecting tube three are made of rubber. The outer diameter of the end of the connecting tube two near the connecting tube one is slightly larger than the inner diameter of the connecting tube one. The outer diameter of the end of the connecting tube two near the negative pressure generator is slightly larger than the inner diameter of the air inlet of the negative pressure generator. The outer diameter of the end of the connecting tube three near the cup lid is slightly larger than the inner diameter of the hole on the cup lid.

[0009] Furthermore, the sealing assembly includes a rubber ring fixedly connected to the inner wall of the cup lid, and two handles are hinged to the outer wall of the cup lid. Each of the two handles has a snap-fit ​​component, and the two handles are mirror images of each other. The snap-fit ​​component includes a limiting groove four formed in the inner wall of the handle two. A locking block three is fixedly connected to the outer wall of the sputum storage cup, and the limiting groove four is adapted to the locking block three.

[0010] Furthermore, the negative pressure generator described in this application is the Sman Peak SXT-5A, which uses an oil-free, self-lubricating single-cylinder piston pump. The motor drives the piston to reciprocate within the pump cylinder. When the piston moves upward, the pump cylinder volume expands to form a low-pressure chamber, and the one-way valve opens to draw air from the reservoir side. When the piston moves downward, the pump cylinder volume shrinks and the pressure increases, the one-way valve closes, and the gas is discharged through the exhaust port. This continuous cycle achieves continuous air extraction to stably generate negative pressure. With a negative pressure regulating device, the negative pressure can be steplessly adjusted. The negative pressure gauge displays the pressure value in real time. The generated negative pressure will cause the sputum collection cup to generate negative pressure synchronously through the connecting pipe two. Under the action of this negative pressure, the sputum in the patient's respiratory tract will be drawn into the sputum collection cup through the connecting pipe three.

[0011] This utility model has the following beneficial effects: 1. By setting up a disassembly and assembly part, when in use, the first locking block is inserted into the first limiting groove to squeeze the slider. The spring telescopic rod is compressed to generate elastic force, and the slider is locked on the top of the first locking block under the action of elastic force to achieve initial limiting. In the locking assembly, the first handle is pulled to make the second locking block disengage from the second limiting groove. After the first handle is released, the spring drives the first handle to return to its original position, and the second locking block is locked into the second and third limiting grooves to complete the fixation of the slider. The reverse operation can unlock the slider and remove the sputum collection cup. This can achieve a stable installation of the sputum collection cup and prevent the sputum collection cup from falling off the connecting block due to the shift of the center of gravity when the suction device or the patient moves, thereby preventing sputum leakage. It also provides convenient conditions for disassembling the sputum collection cup. 2. By setting a sealing part, during assembly, connecting tube one is installed on the inner wall of the cup lid, connecting tube two is inserted into connecting tube one and connected to the negative pressure generator, and connecting tube three is installed inside the cup lid for access to the patient's airway; in the sealing assembly, the cup lid is closed on the sputum collection cup, and pressing handle two causes the locking block three to engage with the limiting groove four. The rubber ring undergoes elastic deformation after being squeezed. Through structural cooperation, the cup lid and the sputum collection cup are sealed and fixed, which can ensure the stability of sputum suction, effectively prevent sputum leakage during suctioning or movement, ensure the cleanliness and hygiene of the suctioning operation, and facilitate the disassembly of the cup lid for subsequent cleaning.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

By setting the disassembly part 2, the sputum cup 217 can be stably installed, avoiding the sputum cup 217 from falling off the connecting block 211 due to the shift of the center of gravity when the suction device or the patient moves, thereby preventing sputum leakage. It also provides convenient conditions for disassembling the sputum cup 217.

[0019] The sealing part 3 includes a flow assembly 31, which is installed on the top of the sputum collection cup 217; and a sealing assembly 32, which is disposed on the sputum collection cup 217. The flow assembly 31 includes a cup lid 311 disposed above the sputum collection cup 217. A connecting tube 312 is disposed on the inner wall of the cup lid 311. A filter plate 313 is fixedly connected to the inner wall of the connecting tube 312. A connecting member is disposed on the cup lid 311. The cup lid 311 has two through holes. The connecting tube 312 is made of rubber and is slightly larger than the inner diameter of the holes on the cup lid 311. The filter plate 313 is used to prevent sputum from entering the connecting tube 312 and to ensure normal air circulation. The connecting member includes a connecting tube 314 disposed inside the connecting tube 312 and a connecting tube 315 disposed inside the cup lid 311. Both the connecting tube 314 and the connecting tube 315 are made of rubber, and the outer diameter of the end of the connecting tube 314 near the connecting tube 312 is slightly larger than that of the connecting tube 312. The inner diameter of the first pipe 312 is slightly larger than the inner diameter of the air inlet of the second pipe 314 near the negative pressure generator 101. The outer diameter of the third pipe 315 near the cup lid 311 is slightly larger than the inner diameter of the hole on the cup lid 311. The sealing assembly 32 includes a rubber ring 321 fixedly connected to the inner wall of the cup lid 311. The outer wall of the cup lid 311 is hinged with two handles 322. Each handle 322 has a snap-fit ​​component. The two 322 are mirror images of each other. The snap-fit ​​part includes a limiting groove 323 on the inner wall of the handle 322. The outer wall of the sputum collection cup 217 is fixedly connected to the locking block 324. The limiting groove 323 and the locking block 324 are adapted to each other. By setting the sealing part 3, the stability of sputum suction can be ensured, and sputum leakage can be effectively prevented during sputum suction or movement, ensuring the cleanliness and hygiene of sputum suction operation. At the same time, it can facilitate the disassembly of the cup lid 311 for subsequent cleaning.

[0020] One specific application of this embodiment is as follows: When in use, the cup lid 311 can be placed on the sputum collection cup 217, and then the two handles 322 are aligned with the two locking blocks 324 respectively, and the handles 322 are pressed down to make the locking blocks 324 engage in the limiting groove 323. During this process, the rubber ring 321 will be squeezed and undergo elastic deformation, thereby generating elastic force. After the locking blocks 324 are engaged in the limiting groove 323, the deformation will be slightly reset under the action of part of the elastic force of the rubber ring 321, and the remaining elastic force will ensure the sealing between the cup lid 311 and the sputum collection cup 217. After installing the cup lid 311, you can insert the first connecting tube 312 into the cup lid 311 and make the filter plate 313 face the inside of the cup lid 311. Then, insert the second connecting tube 314 into the first connecting tube 312 and insert the other end of the second connecting tube 314 into the negative pressure generator 101. After that, you can insert the third connecting tube 315 into the cup lid 311. After inserting the connecting tube 1 312, connecting tube 2 314 and connecting tube 3 315, you can pull the handle 1 221 to make it rotate around the connection between the handle 1 221 and the connecting block 211. At this time, since the two ends of the spring 222 are fixedly connected to the connecting block 211 and the limiting groove 1 212 respectively, the spring 222 will be stretched and generate elastic force. During the process of pulling handle 1 221, it will also drive the block 2 223, which is fixedly connected to handle 1 221, away from the limit groove 2 224 and the limit groove 3 225. Finally, the limit groove 2 224 will lose the restriction of the block 2 223. At this time, the locking block 215 can be inserted into the limiting groove 212, thereby squeezing the slider 213 and causing it to slide into the connecting block 211. Since the two ends of the spring telescopic rod 214 are fixedly connected to the slider 213 and the connecting block 211 respectively, the spring telescopic rod 214 will compress and generate elastic force during the process of the slider 213 sliding into the connecting block 211. When the locking block 215 is completely slid into the limiting groove 212 and contacts the bottom of the limiting groove 212, the limiting groove 212 is completely away from the slider 213. At this time, under the action of the elastic force of the spring telescopic rod 214, the slider 213 will be driven to be locked on the top of the locking block 215, thereby completing the limiting. Then, the handle 221 can be released, allowing it to reset under the force of the spring 222, thereby causing the locking block 223 to engage with the limiting groove 224 and the limiting groove 325, thus completing the limiting of the slider 213; After installation, the connecting tube 315 can be inserted into the patient's airway. At the same time, the negative pressure generator 101 can be operated. It uses an oil-free self-lubricating single-cylinder piston pump. The motor drives the piston to reciprocate in the pump cylinder. When the piston moves upward, the volume of the pump cylinder expands to form a low-pressure chamber. The one-way valve opens to draw air from the reservoir side. When the piston moves downward, the volume of the pump cylinder shrinks and the pressure increases. The one-way valve closes and the gas is discharged through the exhaust port. The continuous cycle achieves continuous air suction to stably generate negative pressure. With the negative pressure regulating device, the negative pressure can be steplessly adjusted. The negative pressure gauge displays the pressure value in real time. The generated negative pressure will cause the sputum collection cup 217 to generate negative pressure synchronously through the connecting tube 214. Under the action of this negative pressure, the sputum in the patient's airway will be drawn into the sputum collection cup 217 through the connecting tube 315. When it is necessary to remove the sputum collection cup 217, the locking component 22 can be reversed to unlock the slider 213. Then, the first locking block 215 can be pulled out of the first limiting groove 212. Next, the first connecting tube 312, the second connecting tube 314, and the third connecting tube 315 can be removed from the cup lid 311. Then, the second handle 322 can be opened to open the cup lid 311. Then, the sputum collection cup 217 and the cup lid 311 and other components can be cleaned.
